The Vikings Wayfaring Way

In the last century, Vikings have been perceived in numerous different ways – vilified as conquerors and romanticised as adventurers. How Vikings have been employed in nation-building is a topic of some interest.

In English, Vikings are also known as Norse or Norsemen. Their language greatly influenced English, with the nouns, ‘Hell’, ‘husband’, ‘law’, and ‘window’, and the verbs, ‘blunder’, ‘snub’, ‘take’, and ‘want’, all coming from Old Norse. However, the origins of the word ‘Viking’, itself, are obscure: it may mean ‘a Scandinavian pirate’, or it may refer to ‘an inlet’, or a place called Vik, in modem-day Norway, from where the pirates came. These various names – Vikings, Norse, or Norsemen, and doubts about the very word ‘Viking’ suggest historical confusion.

Loosely speaking, the Viking Age endured from the late eighth to the mid-eleventh centuries. Vikings sailed to England in AD 793 to storm coastal monasteries, and subsequently, large swathes of England fell under Viking rule – indeed several Viking kings sat on the English throne. It is generally agreed that the Battle of Hastings, in 1066, when the Norman French invaded, marks the end of the English Viking Age, but the Irish Viking age ended earlier, while Viking colonies in Iceland and Greenland did not dissolve until around AD 1500.

How much territory Vikings controlled is also in dispute – Scandinavia and Western Europe certainly, but their reach east and south is uncertain. They plundered and settled down the Volga and Dnieper rivers, and traded with modem-day Istanbul, but the archaeological record has yet to verify that Vikings raided as far away as Northwest Africa, as some writers claim.

The issue of control and extent is complex because many Vikings did not return to Scandinavia after raiding but assimilated into local populations, often becoming Christian. To some degree, the Viking Age is defined by religion. Initially, Vikings were polytheists, believing in many gods, but by the end of the age, they had permanently accepted a new monotheistic religious system – Christianity.

This transition from so-called pagan plunderers to civilised Christians is significant and is the view promulgated throughout much of recent history. In the UK, in the 1970s for example, schoolchildren were taught that until the Vikings accepted Christianity they were nasty heathens who rampaged throughout Britain. By contrast, today’s children can visit museums where Vikings are celebrated as merchants, pastoralists, and artists with a unique worldview as well as conquerors.

What are some other interpretations of Vikings? In the nineteenth century, historians in Denmark, Norway, and Sweden constructed their own Viking ages for nationalistic reasons. At that time, all three countries were in crisis. Denmark had been beaten in war and ceded territory to what is now Germany. Norway had become independent from Sweden in 1905 but was economically vulnerable, so Norwegians sought to create a separate identity for themselves in the past as well as the present. The Norwegian historian, Gustav Storm, was adamant it was his forebears and not the Swedes’ or Danes’ who had colonised Iceland, Greenland, and Vinland, in what is now Canada. Sweden, meanwhile, had relinquished Norway to the Norwegians and Finland to the Russians; thus, in the late nineteenth century, Sweden was keen to boost its image with rich archaeological finds to show the glory of its Viking past.

In addition to augmenting nationalism, nineteenth-century thinkers were influenced by an Englishman, Herbert Spencer, who described peoples and cultures in evolutionary terms similar to those of Charles Darwin. Spencer coined the phrase ‘survival of the fittest’, which includes the notion that, over time, there is not only technological but also moral progress. Therefore, Viking heathens’ adoption of Christianity was considered an advantageous move. These days, historians do not compare cultures in the same way, especially since, in this case, the archaeological record seems to show that heathen Vikings and Christian Europeans were equally brutal.

Views of Vikings change according to not only to forces affecting historians at the time of their research but also according to the materials they read. Since much knowledge of Vikings comes from literature composed up to 300 years after the events they chronicle, some Danish historians cal1 these sources ‘mere legends’.

Vikings did have a written language carved on large stones, but as few of these survive today, the most reliable contemporary sources on Vikings come from writers from other cultures, like the ninth-century Persian geographer, Ibn Khordadbeh.

In the last four decades, there have been wildly varying interpretations of the Viking influence in Russia. Most non-Russian scholars believe the Vikings created a kingdom in western Russia and modern-day Ukraine led by a man called Rurik. After AD 862, Rurik’s descendants continued to rule. There is considerable evidence of this colonisation: in Sweden, carved stones, still standing, describe the conquerors’ journeys; both Russian and Ukrainian have loan words from Old Norse; and, Scandinavian first names, like Igor and Olga, are still popular. However, during the Soviet period, there was an emphasis on the Slavic origins of most Russians. (Appearing in the historical record around the sixth century AD, the Slavs are thought to have originated in Eastern Europe.) This Slavic identity was promoted to contrast with that of the neighbouring Viking Swedes, who were enemies during the Cold War.

These days, many Russians consider themselves hybrids. Indeed recent genetic studies support a Norse-colonisation theory: western Russian DNA is consistent with that of the inhabitants of a region north of Stockholm in Sweden.

The tools available to modern historians are many and varied, and their findings may seem less open to debate. There are linguistics, numismatics, dendrochronology, archaeozoology, palaeobotany, ice crystallography, climate and DNA analysis to add to the translation of runes and the raising of mighty warships. Despite these, historians remain children of their times.

The Future Never Dies?

The prospects for humanity and for the world as a whole are somewhere between glorious and dire. It is hard to be much more precise.

A By ‘glorious’, I mean that our descendants – all who are born on to this Earth – could live very comfortably and securely, and could continue to do so for as long as the Earth can support life, which should be for a very long time indeed. We should at least be thinking in terms of the next million years. Furthermore, our descendants could continue to enjoy the company of other species – establishing a much better relationship with them than we have now. Other animals need not live in constant fear of us. Many of those fellow species now seem bound to become extinct, but a significant proportion could and should continue to live alongside us. Such a future may seem ideal, and so it is. Yet I do not believe it is fanciful. There is nothing in the physical fabric of the Earth or in our own biology to suggest that this is not possible.

B ‘Dire’ means that we human beings could be in deep trouble within the next few centuries, living but also dying in large numbers in political terror and from starvation, while huge numbers of our fellow creatures would simply disappear, leaving only the ones that we find convenient – chickens, cattle – or that we can’t shake off, like flies and mice. I’m taking it to be self-evident that glory is preferable.

C Our future is not entirely in our own hands because the Earth has its own rules, is part of the solar system and is neither stable nor innately safe. Other planets in the solar system are quite beyond habitation, because their temperature is far too high or too low to be endured, and ours, too, in principle could tip either way. Even relatively unspectacular changes in the atmosphere could do the trick. The core of the Earth is hot, which in many ways is good for living creatures, but every now and again, the molten rock bursts through volcanoes on the surface. Among the biggest volcanic eruptions in recent memory was Mount St Helens, in the USA, which threw out a cubic kilometre of ash – fortunately, in an area where very few people live. In 1815, Tambora (in present-day Indonesia) expelled so much ash into the upper atmosphere that climatic effects seriously harmed food production around the world for the season after season. Entire civilisations have been destroyed by volcanoes.

D Yet nothing we have so far experienced shows what volcanoes can really do. Yellowstone National Park in the USA occupies the caldera (the crater formed when a volcano collapses) of an exceedingly ancient volcano of extraordinary magnitude. Modem surveys show that its centre is now rising. Sometime in the next 200 million years, Yellowstone could erupt again, and when it does, the whole world will be transformed. Yellowstone could erupt tomorrow. But there’s a very good chance that it will give us another million years, and that surely is enough to be going on with. It seems sensible to assume that this will be the case.

E The universe at large is dangerous, too: in particular, we share the sky with vast numbers of asteroids, and now and again, the come into our planet’s atmosphere. An asteroid the size of a small island, hitting the Earth at 15,000 kilometres an hour (a relatively modest speed by the standards of heavenly bodies), would strike the ocean bed like a rock in a puddle, send a tidal wave around the world as high as a small mountain and as fast as a jumbo jet, and propel us into an ice age that could last for centuries. There are plans to head off such disasters (including rockets to push approaching asteroids into new trajectories), but in truth, it’s down to luck.

F On the other hand, the archaeological and the fossil evidence shows that no truly devastating asteroid has struck since the one that seems to have accounted for the extinction of the dinosaurs 65 million years ago. So again, there seems no immediate reason for despair. The Earth is indeed an uncertain place, in an uncertain universe, but with average luck, it should do us well enough. If the world does become inhospitable in the next few thousand or million years, then it will probably be our own fault. In short, despite the underlying uncertainty, our own future and that of our fellow creatures are very much in our own hands.

G Given average luck on the geological and the cosmic scale, the difference between glory and disaster will be made and is being made, by politics. Certain kinds of political systems and strategies would predispose us to long-term survival (and indeed to comfort and security and pleasure of being alive), while others would take us more and more frenetically towards collapse. The broad point is, though, that we need to look at ourselves – humanity – and at the world in general in a quite new light. Our material problems are fundamentally those of biology. We need to think, and we need our politicians to think, biologically. Do that, and take the ideas seriously, and we are in with a chance. Ignore biology and we and our fellow creatures haven’t a hope.

Cosmetics In Ancient Past

A Since cosmetics and perfumes are still in wide use today, it is interesting to compare the attitudes, customs and beliefs related to them in ancient times to those of our own day and age. Cosmetics and perfumes have been popular since the dawn of civilization; it is shown by the discovery of a great deal of pertinent archaeological material, dating from the third millennium BC. Mosaics, glass perfume flasks, stone vessels, ovens, cooking-pots, clay jars, etc., some inscribed by the hand of the artisan. Evidence also appears in the Bible and other classical writings, where it is written that spices and perfumes were prestigious products known throughout the ancient world and coveted by kings and princes. The written and pictorial descriptions, as well as archaeological findings, all show how important body care and aesthetic appearance were in the lives of the ancient people. The chain of evidence spans many centuries, detailing the usage of cosmetics in various cultures from the earliest period of recorded history.

B In antiquity, however, at least in the onset, cosmetics served in religious ceremonies and for healing purposes. Cosmetics were also connected with cultic worship and witchcraft: to appease the various gods, fragrant ointments were applied to the statuary images and even to their attendants. From this, in the course of time, developed the custom of personal use, to enhance the beauty of the face and the body, and to conceal defects.

C Perfumes and fragrant spices were precious commodities in antiquity, very much in demand, and at times even exceeded silver and gold in value. Therefore they were luxury products, used mainly in the temples and in the homes of the noble and wealthy. The Judean kings kept them in treasure houses (2 Kings 20:13). And the Queen of Sheba brought to Solomon “camels laden with spices, gold in great quantity and precious stones.” (1 Kings 10:2, 10). However, within time, the use of cosmetics became the custom of that period. The use of cosmetics became widespread among the lower classes as well as among the wealthy; in the same way, they washed the body, so they used to care for the body with substances that softened the skin and anoint it with fragrant oils and ointments.

D Facial treatment was highly developed and women devoted many hours to it. They used to spread various scented creams on the face and to apply makeup in vivid and contrasting colors. An Egyptian papyrus from the 16th century BC contains detailed recipes to remove blemishes, wrinkles, and other signs of age. Greek and Roman women would cover their faces in the evening with a “beauty mask” to remove blemishes, which consisted mainly of flour mixed with fragrant spices, leaving it on their face all night. The next morning they would wash it off with asses’ milk. The very common creams used by women in the ancient Far East, particularly important in the hot climate and prevalent in that area of the globe, were made up of oils and aromatic scents. Sometimes the oil in these creams was extracted from olives, almonds, gourds, sesame, or from trees and plants; but, for those of limited means, scented animal and fish fats were commonly used.

E Women in the ancient past commonly put colors around their eyes. Besides beautification, its purpose was also medicinal as covering the sensitive skin of the lids with colored ointments that prevented dryness and eye diseases: the eye-paint repelled the little flies that transmitted eye inflammations. Egyptian women colored the upper eyelid black and the lower one green and painted the space between the upper lid and the eyebrow gray and blue. The women of Mesopotamia favored yellows and reds. The use of kohl for painting the eyes is mentioned three times in the Bible, always with disapproval by the sages (2 Kings, 9:30; Jeremiah 4:30; Ezekiel 23:40). In contrast, Job named one of his daughters “Keren Happukh”- “horn of eye paint” (Job 42:14)

F Great importance was attached to the care for hair in ancient times. Long hair was always considered a symbol of beauty, and kings, nobles and dignitaries grew their hair long and kept it well-groomed and cared for. Women devoted much time to the style of the hair; while no cutting, they would apply much care to it by arranging it skillfully in plaits and “building it up” sometimes with the help of wigs. Egyptian women generally wore their hair flowing down to their shoulders or even longer. In Mesopotamia, women cherished long hair as a part of their beauty, and hair flowing down their backs in a thick plait and tied with a ribbon is seen in art. Assyrian women wore their hair shorter, braiding and binding it in a bun at the back. In Ancient Israel, brides would wear their hair long on the wedding day as a sign of their virginity. Ordinary people and slaves, however, usually wore their hair short, mainly for hygienic reasons, since they could not afford to invest in the kind of treatment that long hair required.

G From the Bible and Egyptian and Assyrian sources, as well as the words of classical authors, it appears that the centers of the trade-in aromatic resins and incense were located in the kingdoms of southern Arabia, and even as far as India, where some of these precious aromatic plants were grown. “Dealers from Sheba and Rammah dealt with you, offering the choicest spices…” (Ezekiel 27:22). The Nabateans functioned as the important middlemen in this trade; Palestine also served as a very important component, as the trade routes crisscrossed the country. It is known that the Egyptian Queen Hatsheput (15th century BC) sent a royal expedition to the Land of Punt (Somalia) in order to bring back myrrh seedlings to plant in her temple. In Assyrian records of tribute and spoils of war, perfumes and resins are mentioned; the text from the time of Tukulti-Ninurta II (890-884 BC) refers to balls of myrrh as a part of the tribute brought to the Assyrian king by the Aramaean kings. The trade-in spices and perfumes are also mentioned in the Bible as written in Genesis (37:25-26), “Camels carrying gum tragacanth and balm and myrrh”.

The role of accidents in business

In 1894 Dr John Kellogg and his brother. Will, were supervising a hospital and health spa in Michigan. The patients were on a restricted diet. One day, the brothers left cooked wheat untended for more than 24 hours. When they returned, they saw what they had done. It was no good to eat, but they decided to run the stale wheat through rollers, just to see how it would turn out. Normally, the process produced long sheets, but they were surprised to discover that this time the rollers created flat flakes. They baked them, and then tried the same thing with corn. From this accidental discovery came the cornflakes that generations have now been eating for breakfast.

Accidents happen; there is nothing predictable and orderly about innovation. Nobel laureate Sir Alan Hodgkin, who discovered how nerve cells transmit electrical impulses between the skin and the brain, commented: ‘I believe that the record of my published papers conveys an impression of directedness and planning which does not at all coincide with the actual sequence of events.’

The same rule applies in business. The mistake that gave US cornflakes keeps repeating itself in the history of disruptive innovation, the kind that transforms markets. Louis Daguerre, for, instance, discovered the technique that gave US photography in the 1830s, when drops of mercury from a shattered thermometer produced a photographic image. The microwave was discovered when Peroy Spender, a scientist with Raytheon, was testing a new vacuum tube and discovered that the sweet in his pocket had melted. The artificial sweetener, saccharin, was the unintentional result of a medical scientist’s work on a chemical treatment for gastric ulcers. While working for the firm 3M, researcher Art Fry had no idea he was taking the first steps towards Post- It Notes when he used bits of adhesive office paper that could be easily lifted off the page to replace the scrap paper bookmarks that kept falling out of his hymn book.

Breakthrough and disruptive innovation are rarely driven by orderly process. Usually they come out of a chaotic, haphazard mess, which is why big companies, full of managers schooled in business programmes designed to eliminate random variation and mistakes, struggle with them. In these sorts of environments, accidents are called failures and are discouraged.

It is no surprise then that research from the late British economist Paul Geroski and London Business School’s Constantinos Markides found that companies that were skilled at innovation were usually not that skilled when it came to commercialisation, and vice versa. Their book, Fast Second, divides businesses into ‘colonists’ and ‘consolidators’. Small and nimble, colonists are adept at creating market niches but are terrible institution builders. Consolidators, with their strong cultures of discipline and cost control, know how to take clever ideas from other firms and turn them into mass­market items. Microsoft is a prime instance of this.

With companies spending hundreds of billions of dollars on research and development, US academics Robert Austin and Lee Devin examined how managers can encourage productive slip-ups. In their article Accident, Intention and Expectation in the Innovation Process, they argue that business processes actually prevent helpful mis-steps from occurring. According to their catalogue of accidents, not all false steps and mishaps are equal. Accidents, they say, come from unlikely mental associations such as memories and vague connections, looking for something and finding it in an unexpected way, looking for one thing and finding something else, and not looking for anything but finding something valuable.

Accident-prone innovation, they say, requires companies to get outside the ‘cone of expectation’. It means throwing together groups from diverse backgrounds, and combining ideas in unpredictable ways, other strategies also include having systems that watch out for accidents and examine them for value, generating them when they do not happen often enough, seizing oil the useful ones, capturing their valuable features, and building on them to add value and give potential for useful accidents.

All this, however, requires thinking that is often counter-intuitive to the way businesses operate. In other words, it is the kind of thinking that goes against the beliefs of most business managers. It runs counter to the notion frequently pushes by consultants that you can ‘harness’ creativity and direct it to line up with intention. ‘The cost of accidents business, people tend to call such efforts failure.’

There are tentative signs that more companies are starting to realise that failure can lead to commercial gain, and that this is part or the risk-talking that underpins innovation. Australia’s largest brewing company, for example, made a bad error when it launched a new beer called Empire Lager, pitched at younger consumers. Having spent a fortune creating a beer with a sweeter taste, designing a great-looking bottle and a television campaign, Foster’s was left with a drink that no-one wanted to buy. The target market was more interested in brands built up by word of mouth.

Instead of wiping the unsuccessful product launch, Fosters used this lesson learned to go on and develop other brands instead. One of them, Pure Blonde, is now ranked as Australia’s fifth-largest beer brand. Unlike Empire Lager, there has been almost no promotion and its sales are generated more by word of mouth.

Other companies are taking similar steps to study their own slip-ups. Intuit, the company behind financial tools such as Quicken, holds regular ‘When Learning Hurts’ sessions. But this sort of transformation is never easy. In a market that focuses on the short-term, convincing employees and shareholders to tolerate failure and not play it safe is a big thing to ask.

Olive Oil Production

Olive oil has been one of the staples of the Mediterranean diet for thousands of years and its popularity is growing rapidly in other parts of the world. It is one of the most versatile oils for cooking and it enhances the taste of many foods. Olive oil is the only type of vegetable/fruit oil that can be obtained from just pressing. Most other types of popular oils (corn, canola, etc.) must be processed in other ways to obtain the oil. Another important bonus is that olive oil has proven health benefits. Three basic grades of olive oil are most often available to the consumer: extra Virgin, Virgin and Olive Oil. In addition to the basic grades, olive oil differs from one country or region to another because of the types of olives that are grown, the harvesting methods, the time of the harvest, and the pressing techniques. These factors all contribute to the individual characteristics of the olive oil.

Olive trees must be properly cared for in order to achieve good economic yields. Care includes regular irrigation, pruning, fertilizing, and killing pests. Olives will survive on very poor sites with shallow soils but will grow very slowly and yield poorly. Deep soils tend to produce excessively vigorous trees, also with lower yields. The ideal site for olive oil production is a clay loam soil with good internal and surface drainage. Irrigation is necessary to produce heavy crops and avoid alternate bearing. The site must be free of hard winter frosts because wood damage will occur at temperatures below 15°F and a lengthy spell of freezing weather can ruin any chances for a decent crop. The growing season also must be warm enough so fruits mature before even light fall frosts (usually by early November) because of potential damage to the fruit and oil quality. Fortunately, olive trees are very hardy in hot summer temperatures and they are drought tolerant.

The best olive oils hold a certificate by an independent organization that authenticates the stone ground and cold pressed extraction process. In this process, olives are first harvested by hand at the proper stage of ripeness and maturity. Experts feel that hand harvesting, as opposed to mechanical harvesting, eliminates bruising of the fruit which causes tartness and oil acidity. The olives harvested are transferred daily to the mill. This is very important because this daily transfer minimizes the time spent between picking and pressing. Some extra virgin olive oil producers are known to transfer the olives by multi-ton trucks over long distances that expose the fragile fruit to crushing weight and the hot sun, which causes the olives to begin oxidizing and thus becoming acidic. In addition to the time lapse between harvesting and pressing, olive oil must be obtained using mechanical processes only to be considered virgin or extra virgin. If heat and/or chemical processes are used to produce the olive oil or if the time lapse is too long, it cannot be called virgin or extra virgin.

Once at the mill, the leaves are sucked away with air fans and the olives are washed with circulating potable water to remove all impurities. The first step of extraction is mashing the olives to create a paste. The oil, comprising 20% to 30% of the olive, is nestled in pockets within the fruit’s cells. The olives are crushed in a mill with two granite millstones rolling within a metal basin. Crushing and mixing the olives releases the oil from the cells of the olive without heating the paste. A side shutter on the mill’s basin allows the mixed olive paste to be discharged and applied to round mats. The mats are stacked and placed under the head of a hydraulic press frame that applies downward pressure and extracts the oil. The first pressing yields the superior quality oil, and the second and third pressings produce inferior quality oil. Some single estate producers collect the oil that results from just the initial crushing while many other producers use an additional step to extract more oil. The olive pulp is placed on mats constructed with hemp or polypropylene that are stacked and then pressed to squeeze the pulp. Oil and water filter through the mats to a collection tank below. The water and oil are then separated in a centrifuge.

Regardless of the method used for the first pressing, the temperature of the oil during production is extremely important in order to maintain the distinct characteristics of the oil. If the temperature of the oil climbs above 86ºF, it will be damaged and cannot be considered cold-pressed.

The first pressing oil contains the most “polyphenols”, substances that have been found to be powerful antioxidants capable of protecting against certain types of disease. The polyphenols are not the only substances in the olive with health-promoting effects, but they are quite unique when compared to other commonly used culinary oils such as sunflower and soy. It is these polyphenols that really set extra virgin olive oils apart from any other oil and any other form of olive oil. The more refined the olive oil is, the smaller the quantity of polyphenols.

The result of the producers’ efforts is a cold pressed extra virgin olive oil with high quality standards and organoleptic characteristics, which give the oil its health-protective and aromatic properties.

UNDOING OUR EMOTIONS

A. Three generations ago, 180 young women wrote essays describing why they wanted to join a convent (a religious community of nuns). Years later, a team of psychological researchers came across these autobiographies in the convent’s archives. The researchers were seeking material to confirm earlier studies hinting at a link between having a good vocabulary in youth and a low risk of Alzheimer’s disease in old age. What they found was even more amazing. The researchers found that, although the young women were in their early twenties when they wrote their essays, the emotions expressed in these writings were predictive of how long they would live: those with upbeat autobiographies lived more than ten years longer than those whose language was more neutral. Deborah Danner, a psychologist at the University of Kentucky who spearheaded the study, noted that the results were particularly striking because all members of the convent lived similar lifestyles, eliminating many variables that normally make it difficult to interpret longevity studies. It was a phenomenal finding’, she says. ‘A researcher gets a finding like that maybe once in a lifetime.’ However, she points out that no one has been able to determine why positive emotions might have such life-extending effects.

B. Barbara Fredrickson, Professor of Psychology at the University of Michigan, believes that part of the answer is the ‘undo effect’. According to this theory, positive emotions help you live longer by shutting down the effects of negative ones. Fredrickson’s theory begins with the observation that negative emotions, like fear and stress, enhance our flight-or-fight response to very real threats. However, even when the emergency is gone, negative emotions produce lingering effects. Brooks Gump, a stress researcher at the State University of New York, explains that one of these effects is excessive cardiovascular reactivity. Behaviourally, Gump says, this reactivity is related to excessive vigilance: the state of being constantly on guard for potential dangers. Not only is it physically draining to live in a perpetual state of high vigilance, but high cardiovascular reactivity could be linked to increased chances of a heart attack.

C. Fredrickson believes positive emotions work their magic by producing a rapid unwinding of pent-up tension, restoring the system to normal. People who quickly bounce back from stress often speed the process by harnessing such emotions as amusement, interest, excitement, and happiness, she says. To test her theory, Fredrickson told a group of student volunteers that they had only a few minutes to prepare a speech that would be critiqued by experts. After letting the students get nervous about that, Fredrickson then told them they wouldn’t actually have to deliver their speeches. She monitored heart rates and blood pressure. Not surprisingly, all students got nervous about their speeches, but those who viewed the experiment with good-humored excitement saw their heart rates return to normal much more quickly than those who were angry about being fooled. In a second experiment, Fredrickson reported that even those who normally were slow to bounce back could be coached to recover more quickly by being told to view the experiment as a challenge, rather than a threat.

D. Fredrickson believes that positive emotions make people more flexible and creative. Negative emotions, she says, give a heightened sense of detail that makes us hypersensitive to minute clues related to the source of a threat. But that also produces ‘tunnel vision’ in which we ignore anything unrelated to the danger. Fredrickson speculated that just as positive emotions can undo the cardiovascular effects of negative ones, they may also reverse the attention-narrowing effects of negative feelings: broadening our perspectives.

E. To verify her theory, Fredrickson showed a group of students some film clips- some saw frightening clips, some saw humorous ones or peaceful ones. They then did a matching test in which they were shown a simple drawing and asked which of two other drawings it most resembled. The drawings were designed so that people would tend to give one answer if they focused on details, and another answer if they focused on the big picture. The results confirmed Fredrickson’s suspicion that positive emotions affect our perceptions. Students who had seen the humorous or peaceful clips were more likely to match objects according to broad impressions.

F. This fits with the role that positive emotions might have played in early human tribes, Fredrickson says. Negative emotions provided focus, which was important for surviving in life-or-death situations, but the ability to feel positive emotions was of long-term value because it opened the mind to new ideas. Humour is a good example of this. She says: ‘The emotions are transient, but the resources are durable. If you building a friendship through being playful, that friendship is a lasting resource.’ So while the good feelings may pass, the friendship remains. On an individual level, Fredrickson’s theory also says that taking time to do things that make you feel happy isn’t simply self-indulgent. Not only are these emotions good for the individual, but they are also good for society.

G. Other researchers are intrigued by Fredrickson’s findings. Susan Folkman, of the University of California, has spent two decades studying how people cope with long-term stresses such as bereavement, or caring for a chronically ill child. Contrary to what one might expect, she says, these people frequently experience positive emotions. ‘These emotions aren’t there by accident’, she adds. ‘Mother Nature doesn’t work that way, I think that they give a person time out from the intense stress to restore their resources and keep going. This is very consistent with Fredrickson’s work.’

Twin Study: Two of a kind

A. THE scientific study of twins goes back to the late 19th century, when Francis Galton, an early geneticist, realised that they came in two varieties: identical twins born from one egg and non-identical twins that had come from two. That insight turned out to be key, although it was not until 1924 that it was used to formulate what is known as the twin rule of pathology, and twin studies really got going.

B The twin rule of pathology states that any heritable disease will be more concordant (that is, more likely to be jointly present or absent) in identical twins than in non-identical twins – and, in turn, will be more concordant in non-identical twins than in non-siblings. Early work, for example, showed that the statistical correlation of skin-mole counts between identical twins was 0.4, while non-identical twins had a correlation of only 0.2. (A score of 1.0 implies a perfect correlation, while a score of zero implies no correlation.) This result suggests that moles are heritable, but it also implies that there is an environmental component to the development of moles, otherwise, the correlation in identical twins would be close to 1.0.

C Twin research has shown that whether or not someone takes up smoking is determined mainly by environmental factors, but once he does so, how much he smokes is largely down to his genes. And while a person’s religion is clearly a cultural attribute, there is a strong genetic component to religious fundamentalism. Twin studies are also unraveling the heritability of various aspects of human personality. Traits from neuroticism and anxiety to thrill – and novelty-seeking all have large genetic components. Parenting matters, but it does not determine personality in the way that some had thought.

D More importantly, perhaps, twin studies are helping the understanding of diseases such as cancer, asthma, osteoporosis, arthritis and immune disorders. And twins can be used, within ethical, for medical experiments. A study that administered vitamin C to one twin and a placebo to the other found that it had no effect on the common cold. The lesson from all of today’s twin studies is that most human traits are at least partially influenced by genes. However, for the most part, the age-old dichotomy between nature and nurture is not very useful. Many genetic programs are open to input from the environment, and genes are frequently switched on or off by environmental signals. It is also possible that genes themselves influence their environment. Some humans have an innate preference for participation in sports. Others are drawn to novelty. Might people also be drawn to certain kinds of friends and types of experience? In this way, a person’s genes might shape the environment they act in as much as the environment shapes the actions of the genes.

E In the past, such research has been controversial. Josef Mengele, a Nazi doctor working at the Auschwitz extermination camp during the second world war, was fascinated by twins. He sought them out among arrivals at the camp and preserved them from the gas-chambers for a series of brutal experiments. After the war, Cyril Burt, a British psychologist who worked on the heredity of intelligence, tainted twin research with results that appear, in retrospect, to have been rather too good. Some of his data on identical twins who had been reared apart were probably faked. In any case, the prevailing ideology in the social sciences after the war was Marxist and disliked suggestions that differences in human potential might have underlying genetic causes. Twin studies were thus viewed with suspicion.

F The ideological pendulum has swung back; however, as the human genome project and its aftermath have turned genes for abstract concepts to real pieces of DNA. The role of genes in sensitive areas such as intelligence is acknowledged by all but a few die-hards. The interesting questions now concern how nature and nurture interact to produce particular bits of biology, rather than which of the two is more important. Twin studies, which are a good way to ask these questions, are back in fashion, and many twins are enthusiastic participants in this research.

G Research at the Twinsburg festival began in a small way, with a single stand in 1979. Gradually, news spread and more scientists began turning up. This year, half a dozen groups of researchers were lodged in a specially pitched research tent. In one corner of this tent, Paul Breslin, who works at the Monell Institute in Philadelphia, watched over several tables where twins sat sipping clear liquids from cups and making notes. It was the team’s third year at Twinsburg. Dr Breslin and his colleagues want to find out how genes influence human perception, particularly the senses of smell and taste and those (warmth, cold, pain, tingle, itch and so on) that result from stimulation of the skin. Perception is an example of something that is probably influenced by both genes and experience. Even before birth, people are exposed to flavours such as chocolate, garlic, mint and vanilla that pass intact into the bloodstream, and thus to the fetus. Though it is not yet clear whether such pre-natal exposure shapes taste-perception, there is evidence that it shapes preferences for foods encountered later in life.

H However, there are clearly genetic influences at work, as well – for example in the ability to taste quinine. Some people experience this as intensely bitter, even when it is present at very low levels. Others, whose genetic endowment is different, are less bothered by it. Twin studies make this extremely clear. Within a pair of identical twins, either both, or neither, will find quinine hard to swallow. Non-identical twins will agree less frequently.

I On the other side of the tent Dennis Drayna, from the National Institute on Deafness and Other Communication Disorders, in Maryland, was studying hearing. He wants to know what happens to sounds after they reach the ear. It is not clear, he says, whether the sound is processed into sensation mostly in the ear or in the brain. Dr Drayna has already been involved in a twin study which revealed that the perception of musical pitch is highly heritable. At Twinsburg, he is playing different words, or parts of words, into the left and right ears of his twinned volunteers. The composite of the two sounds that an individual reports hearing depends on how he processes this diverse information and that, Dr Drayna believes, may well be influenced by genetics.

J Elsewhere in the marquee, Peter Miraldi, of Kent State University in Ohio, was trying to find out whether genes affect an individual’s motivation to communicate with others. A number of twin studies have shown that personality and sociability are heritable, so he thinks this is fertile ground. And next to Mr Miraldi was a team of dermatologists from Case Western Reserve University in Cleveland. They are looking at the development of skin disease and male-pattern baldness. The goal of the latter piece of research is to find the genes responsible for making men’s hair fall out.

K The busiest part of the tent, however, was the queue for forensic-science research into fingerprints. The origins of this study are shrouded in mystery. For many months, the festival’s organisers have been convinced that the Secret Service – the American government agency responsible for, among other things, the safety of the president – is behind it. When The Economist contacted the Secret Service for more information, we were referred to Steve Nash, who is chairman of the International Association for Identification (IAI) and is also a detective in the scientific investigations section of the Marin Country Sheriff’s Office in California. The IAI, based in Minnesota, is an organisation of forensic scientists from around the world. Among other things, it publishes the Journal of Forensic Identification.

Facial Expression

A A facial expression is one or more motions or positions of the muscles in the skin. These movements convey the emotional state of the individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information among aliens, but also occur in most other mammals and some other animal species. Facial expressions and their significance in the perceiver can, to some extent, vary between cultures with evidence from descriptions in the works of Charles Darwin.

B Humans can adopt a facial expression to read as a voluntary action. However, because expressions are closely tied to emotion, they are more often involuntary. It can be nearly impossible to avoid expressions for certain emotions, even when it would be strongly desirable to do so; a person who is trying to avoid insulting an individual he or she finds highly unattractive might, nevertheless, show a brief expression of disgust before being able to reassume a neutral expression. Microexpressions are one example of this phenomenon. The close link between emotion and expression can also work in the order direction; it has been observed that voluntarily assuming an expression can actually cause the associated emotion.

C Some expressions can be accurately interpreted even between members of different species – anger and extreme contentment being the primary examples. Others, however, are difficult to interpret even in familiar individuals. For instance, disgust and fear can be tough to tell apart. Because faces have only a limited range of movement, expressions rely upon fairly minuscule differences in the proportion and relative position of facial features, and reading them requires considerable sensitivity to the same. Some faces are often falsely read as expressing some emotion, even when they are neutral because their proportions naturally resemble those another face would temporarily assume when emoting.

D Also, a person’s eyes reveal much about hos they are feeling, or what they are thinking. Blink rate can reveal how nervous or at ease a person maybe. Research by Boston College professor Joe Tecce suggests that stress levels are revealed by blink rates. He supports his data with statistics on the relation between the blink rates of presidential candidates and their success in their races. Tecce claims that the faster blinker in the presidential debates has lost every election since 1980. Though Tecce’s data is interesting, it is important to recognize that non-verbal communication is multi-channelled, and focusing on only one aspect is reckless. Nervousness can also be measured by examining each candidates’ perspiration, eye contact and stiffness.

E As Charles Darwin noted in his book The Expression of the Emotions in Man and Animals: the young and the old of widely different races, both with man and animals, express the same state of mind by the same movements. Still, up to the mid-20th century, most anthropologists believed that facial expressions were entirely learned and could, therefore, differ among cultures. Studies conducted in the 1960s by Paul Ekman eventually supported Darwin’s belief to a large degree.

F Ekman’s work on facial expressions had its starting point in the work of psychologist Silvan Tomkins. Ekman showed that contrary to the belief of some anthropologists including Margaret Mead, facial expressions of emotion are not culturally determined, but universal across human cultures. The South Fore people of New Guinea were chosen as subjects for one such survey. The study consisted of 189 adults and 130 children from among a very isolated population, as well as twenty-three members of the culture who lived a less isolated lifestyle as a control group. Participants were told a story that described one particular emotion; they were then shown three pictures (two for children) of facial expressions and asked to match the picture which expressed the story’s emotion.

G While the isolated South Fore people could identify emotions with the same accuracy as the non-isolated control group, problems associated with the study include the fact that both fear and surprise were constantly misidentified. The study concluded that certain facial expressions correspond to particular emotions and can not be covered, regardless of cultural background, and regardless of whether or not the culture has been isolated or exposed to the mainstream.

H Expressions Ekman found to be universally included those indicating anger, disgust, fear, joy, sadness, and surprise (not that none of these emotions has a definitive social component, such as shame, pride, or schadenfreude). Findings on contempt (which is social) are less clear, though there is at least some preliminary evidence that this emotion and its expression are universally recognized. This may suggest that the facial expressions are largely related to the mind and each part on the face can express specific emotion.

The Can – A Brief History Lesson

A. The story of the can begins in 1795 when Nicholas Appert, a Parisian, had an idea: why not pack food in bottles like wine? Fifteen years later, after researching and testing his idea, he published his theory: if food is sufficiently heated and sealed in an airtight container, it will not spoil. In 1810 Peter Durand, an Englishman, wanted to surpass Appert’s invention, so he elected to try tin instead of glass. Like glass, tin could be sealed airtight but tin was not breakable and was much easier to handle. Durand himself did no canning, but two other Englishmen, Bryan Donkin and John Hall, used Durand’s patent. After experimenting for more than a year, they set up a commercial canning factory and by 1813 they were sending tins of food to British army and navy authorities for trial.

B. Perhaps the greatest encouragement to the newborn canning industry was the explosion in the number of new colonial territories. As people and goods were being transported to all parts of the world, the can industry itself was growing in new territories. Englishmen who emigrated to America brought their newfound knowledge with them. One of these was Thomas Kensett, who might fairly be called the father of the can manufacturing industry in the United States. In 1812 he set up a small plant on the New York waterfront to can the first hermetically sealed products in the United States.

C. Just before the Civil War, a technical advance by canners enabled them to speed up production. Adding calcium chloride to the water in which cans were cooked raised the water temperature, speeding up the canning process. Also for almost 100 years, tin cans were made by artisans by hand. It was a laborious process, requiring considerable skill and muscle. As the industrial revolution took hold in the United States, the demand for cans increased and machines began to replace the artisans’ handiwork. A good artisan could make only 10 cans a day. True production progress in can-making began in 1922, when American engineers perfected the body-making process. New methods soon increased production of cans to as many as 250 a minute.

D. As early as 1940, can manufacturers began to explore the possibility of adapting cans to package carbonated soft drinks. The can had to be strengthened to accommodate higher internal can pressures created by carbonation (especially during warm summer months), which meant increasing the thickness of the metal used in the can ends. Another concern for the new beverage can was its shelf life. Even small amounts of dissolved tin or iron from the can could impair the drinking quality of drinks. Also the food acids, including carbonic, citric and phosphoric, in soft drinks presented a risk for the rapid corrosion of exposed tin and iron in the can. At this point the can was upgraded by improving the organic coatings used to line the inside. The can manufacturers then embarked on a program of material and cost savings by reducing both the amount of steel and the amount of coating used in can making. These efforts were in part inspired by a new competitor – aluminum.

E. Beverage cans made from aluminum were first introduced in 1965. This was an exciting innovation for the packaging industry because the aluminum can was made with only two pieces – a body and an end. This made production easier. Some of the reasons for the aluminum can’s acceptance were its ductility, its support of carbonation pressure, its lighter weight and the fact that aluminum does not rust. Both steel and aluminum cans used an easy-open end tab but the aluminum tab was much easier to make. Perhaps the most critical element in the aluminum can’s market success was its recycling value. Aluminum can recycling excelled economically in the competition with steel because of the efficiencies aluminum cans realized in making new cans from recycled materials compared with 100 percent virgin aluminum. Steel did not realize similar economies in the recycling process.

F. Prior to 1970, can makers, customers and consumers alike were unaware of the impact that the mining and manufacturing of steel or aluminum had on the environment. The concept of natural resource preservation was not an issue of great importance and the low growth of population during these early years further de-emphasized concerns for resource depletion. Both industries, however, came to realize the importance of reducing their impact on the environment in the late 1960s and early 1970s as a new environmentally conscious generation emerged. Manufacturers began to recognize the economics of recycling, namely lower manufacturing costs from using less material and less energy. By the 1980s and 1990s, recycling had become a way of life. Aluminum can recycling has become a billion-dollar business and one of the world’s most successful environmental enterprises. Over the years, the aluminum can has come to be known as America’s most recyclable package, with over 60 percent of cans being recycled annually.

G. Advances in can manufacturing technology have also brought us lighter aluminum cans. In 1972, one pound of aluminum yielded only 21.75 cans. Today, by using less material to make each can, one pound of aluminum makes approximately 32 cans – a 47 percent improvement. Just the lightening of can ends makes a huge difference. When you multiply the savings by the 100 billion cans that are made each year, the weight and savings are phenomenal – over 200 million pounds of aluminum!

Biology of Bitterness

A. There is a reason why grapefruit juice is served in little glasses: most people don’t want to drink more than a few ounces at a time. aringin, a natural chemical compound found in grapefruit, tastes bitter. Some people like that bitterness in small doses and believe it enhances the general flavor, but others would rather avoid it altogether. So juice packagers often select grapefruit with low naringin though the compound has antioxidant properties that some nutritionists contend may help prevent cancer and arteriosclerosis.

B. It is possible, however, to get the goodness of grapefruit juice without the bitter taste. I found that out by participating in a test conducted at the Linguagen Corporation, a biotechnology company in Cranbury, New Jersey. Sets of two miniature white paper cups, labeled 304and 305, were placed before five people seated around a conference table. Each of us drank from one cup and then the other, cleansing our palates between tastes with water and a soda cracker. Even the smallest sip of 304 had grapefruit ‘s unmistakable bitter bite. But 305 was smoother; there was the sour taste of citrus but none of the bitterness of naringin. This juice had been treated with adenosine monophosphate, or AMP, a compound that blocks the bitterness in foods without making them less nutritious.

C. Taste research is a booming business these days, with scientists delving into all five basics-sweet, bitter, sour, salty, and umami, the savory taste of protein. Bitterness is of special interest to industry because of its untapped potential in food. There are thousands of bitter -tasting compounds in nature. They defend plants by warning animals away and protect animals by letting them know when a plant may be poisonous. But the system isn’t foolproof. Grapefruit and cruciferous vegetable like Brussels sprouts and kale are nutritious despite-and sometimes because of-their bitter-tasting components. Over time, many people have learned to love them, at least in small doses. “Humans are the only species that enjoys bitter taste,” says Charles Zuker, a neuroscientist at the University of California School of Medicine at San Diego. “Every other species is averse to bitter because it means bad news. But we have learned to enjoy it. We drink coffee, which is bitter, and quinine [in tonic water] too. We enjoy having that spice in our lives.” Because bitterness can be pleasing in small quantities but repellent when intense, bitter blockers like AMP could make a whole range of foods, drinks, and medicines more palatable-and therefore more profitable.

D. People have varying capacities for tasting bitterness, and the differences appear to be genetic. About 75 percent of people are sensitive to the taste of the bitter compounds phenylthiocarbamide and 6-n-propylthiouracil. and 25 percent are insensitive. Those who are sensitive to phenylthiocarbamide seem to be less likely than others to eat cruciferous vegetables, according to Stephen Wooding, a geneticist at the University of Utah. Some people, known as supertasters, are especially sensitive to 6-n-propylthiouraci because they have an unusually high number of taste buds. Supertasters tend to shun all kinds of bitter-tasting things, including vegetable, coffee, and dark chocolate. Perhaps as a result, they tend to be thin. They’re also less fond of alcoholic drinks, which are often slightly bitter. Dewar’s scotch, for instance, tastes somewhat sweet to most people. ” But a supertaster tastes no sweetness at all, only bitterness,” says Valerie Duffy, an associate professor of dietetics at the University of Connecticut at Storrs.

E. In one recent study, Duffy found that supertasters consume alcoholic beverages, on average, only two to three times a week, compared with five or six times for the average nontasters. Each taste bud, which looks like an onion, consists of 50 to 100 elongated cells running from the top of the bud to the bottom. At the top is a little clump of receptors that capture the taste molecules, known as tastants, in food and drink. The receptors function much like those for sight and smell. Once a bitter signal has been received, it is relayed via proteins known as G proteins. The G protein involved in the perception of bitterness, sweetness, and umami was identified in the early 1990s by Linguagen’s founder, Robert Margolskee, at Mount Sinai School of Medicine in New York City. Known as gustducin, the protein triggers a cascade of chemical reactions that lead to changes in ion concentrations within the cell. Ultimately, this delivers a signal to the brain that registers as bitter. “The signaling system is like a bucket brigade,” Margolskee says. “It goes from the G protein to other proteins.”

F. In 2000 Zuker and others found some 30 different kinds of genes that code for bitter-taste receptors. “We knew the number would have to be large because there is such a large universe of bitter tastants,” Zuker says. Yet no matter which tastant enters the mouth or which receptor it attaches to, bitter always tastes the same to us. The only variation derives from its intensity and the ways in which it can be flavored by the sense of smell. “Taste cells are like a light switch,” Zuker says. “They are either on or off.”

G. Once they figured put the taste mechanism, scientists began to think of ways to interfere with it. They tried AMP, an organic compound found in breast milk and other substances, which is created as cells break down food. Amp has no bitterness of its own, but when put it in foods, Margolskee and his colleagues discovered, it attaches to bitter-taste receptors. As effective as it is, AMP may not be able to dampen every type pf bitter taste, because it probably doesn’t attach to all 30 bitter-taste receptors. So Linguagen has scaled up the hunt for other bitter blockers with a technology called high-throughput screening. Researchers start by coaxing cells in culture to activate bitter-taste receptors. Then candidate substances, culled from chemical compound libraries, are dropped onto the receptors, and scientists look for evidence of a reaction.

H. Tin time, some taste researchers believe, compounds like AMP will help make processed foods less unhealthy. Consider, for example, that a single cup of Campbell’s chicken noodle soup contains 850 milligrams of sodium chloride, or table salt-more than a third of the recommended daily allowance. The salt masks the bitterness created by the high temperatures used in the canning process, which cause sugars and amino acids to react. Part of the salt could be replaced by another salt, potassium chloride, which tends to be scarce in some people’s diets. Potassium chloride has a bitter aftertaste, but that could be eliminated with a dose of AMP. Bitter blockers could also be used in place of cherry or grape flavoring to take the harshness out of children’s cough syrup, and they could dampen the bitterness of antihistamines, antibiotics, certain HIV drugs, and other medications.

I. A number of foodmakers have already begun to experiment with AMP in their products, and other bitter blockers are being developed by rival firms such as Senomyx in La Jolla, California. In a few years, perhaps, after food companies have taken the bitterness from canned soup and TV dinners, they can set their sights on something more useful: a bitter blocker in a bottle that any of us can sprinkle on our brussels sprouts or stir into our grapefruit juice.

The Dinosaurs Footprints and Extinction

A EVERYBODY knows that the dinosaurs were killed by an asteroid. Something big hit the earth 65 million years ago and, when the dust had fallen, so had the great reptiles. There is thus a nice if ironic, symmetry in the idea that a similar impact brought about the dinosaurs’ rise. That is the thesis proposed by Paul Olsen, of Columbia University, and his colleagues in this week’s Science.

B Dinosaurs first appeared in the fossil record 230m years ago, during the Triassic period. But they were mostly small, and they shared the earth with lots of other sorts of reptile. It was in the subsequent Jurassic, which began 202 million years ago, that they overran the planet and turned into the monsters depicted in the book and movie “Jurassic Park”. (Actually, though, the dinosaurs that appeared on screen were from the still more recent Cretaceous period.) Dr Olsen and his colleagues are not the first to suggest that the dinosaurs inherited the earth as the result of an asteroid strike. But they are the first to show that the takeover did, indeed, happen in a geological eyeblink.

C Dinosaur skeletons are rare. Dinosaur footprints are, however, surprisingly abundant. And the sizes of the prints are as good an indication of the sizes of the beasts as are the skeletons themselves. Dr Olsen and his colleagues, therefore, concentrated on prints, not bones.

D The prints in question were made in eastern North America, a part of the world the full of rift valleys to those in East Africa today. Like the modern African rift valleys, the Triassic/Jurassic American ones contained lakes, and these lakes grew and shrank at regular intervals because of climatic changes caused by periodic shifts in the earth’s orbit. (A similar phenomenon is responsible for modern ice ages.) That regularity, combined with reversals in the earth’s magnetic field, which are detectable in the tiny fields of certain magnetic minerals, means that rocks from this place and period can be dated to within a few thousand years. As a bonus, squishy lake-edge sediments are just the things for recording the tracks of passing animals. By dividing the labour between themselves, the ten authors of the paper were able to study such tracks at 80 sites.

E The researchers looked at 18 so-called ichnotaxa. These are recognizable types of the footprint that cannot be matched precisely with the species of animal that left them. But they can be matched with a general sort of animal, and thus act as an indicator of the fate of that group, even when there are no bones to tell the story. Five of the ichnotaxa disappear before the end of the Triassic, and four march confidently across the boundary into the Jurassic. Six, however, vanish at the boundary, or only just splutter across it; and there appear from nowhere, almost as soon as the Jurassic begins.

F That boundary itself is suggestive. The first geological indication of the impact that killed the dinosaurs was an unusually high level of iridium in rocks at the end of the Cretaceous when the beasts disappear from the fossil record. Iridium is normally rare at the earth’s surface, but it is more abundant in meteorites. When people began to believe the impact theory, they started looking for other Cretaceous-and anomalies. One that turned up was a surprising abundance of fern spores in rocks just above the boundary layer – a phenomenon known as a “fern spike”.

G That matched the theory nicely. Many modern ferns are opportunists. They cannot compete against plants with leaves, but if a piece of land is cleared by, say, a volcanic eruption, they are often the first things to set up shop there. An asteroid strike would have scoured much of the earth of its vegetable cover, and provided a paradise for ferns. A fern spike in the rocks is thus a good indication that something terrible has happened.

H Both an iridium anomaly and a fern spike appear in rocks at the end of the Triassic, too. That accounts for the disappearing ichnotaxa: the creatures that made them did not survive the holocaust. The surprise is how rapidly the new ichnotaxa appear.

I Dr Olsen and his colleagues suggest that the explanation for this rapid increase in size may be a phenomenon called ecological release. This is seen today when reptiles (which, in modern times, tend to be small creatures) reach islands where they face no competitors. The most spectacular example is on the Indonesian island of Komodo, where local lizards have grown so large that they are often referred to as dragons. The dinosaurs, in other words, could flourish only when the competition had been knocked out.

J That leaves the question of where the impact happened. No large hole in the earth’s crust seems to be 202m years old. It may, of course, have been overlooked. Old craters are eroded and buried, and not always easy to find. Alternatively, it may have vanished. Although the continental crust is more or less permanent, the ocean floor is constantly recycled by the tectonic processes that bring about continental drift. There is no ocean floor left that is more than 200m years old, so a crater that formed in the ocean would have been swallowed up by now.

K There is a third possibility, however. This is that the crater is known, but has been misdated. The Manicouagan “structure”, a crater in Quebec, is thought to be 214m years old. It is huge – some 100km across – and seems to be the largest of between three and five craters that formed within a few hours of each other as the lumps of a disintegrated comet hit the earth one by one.

A leap into history

A. Between the Inishowen peninsula, north west of Derry, and the Glens of Antrim, in the east beyond the Sperrin Mountains, is found some of Western Europe’s most captivating and alluring landscape.

B. The Roe Valley Park, some 15 miles east of Derry is a prime example. The Park, like so many Celtic places, is steeped in history and legend. As the Roc trickles down through heather bogs in the Sperrin Mountains to the South, it is a river by the time it cuts through what was once called the ‘garden of the soul’ – in Celtic ‘Gortenanima’.

C. The castle of O’Cahan once stood here and a number of houses which made up the town of Limavady. The town takes its name from the legend of a dog leaping into the river Roe carrying a message, or perhaps chasing a stag. This is a wonderful place, where the water traces its way through rock and woodland; at times, lingering in brooding pools of dark cool water under the shade of summer trees, and, at others, forming weirs and leads for water mills now long gone.

D. The Roe, like all rivers, is witness to history and change. To Mullagh Hill, on the west bank of the River Roe just outside the present day town of Limavady, St Columba came in 575 AD for the Convention of Drumceatt. The world is probably unaware that it knows something of Limavady; but the town is, in fact, renowned for Jane Ross’s song Danny Roy, written to a tune once played by a tramp in the street. Limavady tow n itself and many of the surrounding villages have Celtic roots but no one knows for sure just how old the original settlement of Limavady is.

E. Some 30 miles along the coast road from Limavady, one comes upon the forlorn, but imposing ruin of Dunluce Castle, which stands on a soft basalt outcrop, in defiance of the turbulent Atlantic lashing it on all sides. The jagged­-toothed ruins sit proud on their rock top commanding the coastline to east and west. The only connection to the mainland is by a narrow bridge. Until the kitchen court fell into the sea in 1639 killing several servants, the castle was fully inhabited. In the next hundred years or so, the structure gradually fell into its present dramatic state of disrepair, stripped of its roofs by wind and weather and robbed by man of its caned stonework. Ruined and forlorn its aspect may­be yet, in the haunting Celtic twilight of the long summer evenings, it is redolent of another age, another dream.

F. A mile or so to the east of the castle lies Port na Spaniagh, where the Neapolitan Galleas, Girona, from the Spanish Armada went down one dark October night in 1588 on its way to Scotland, of the 1500-odd men on board, nine survived.

G. Even further to the east, is the Giant’s Causeway stunning coastline with strangely symmetrical columns of dark basalt – a beautiful geological wonder. Someone once said of the Causeway that it was worth seeing, but not worth going to see. That was in thê days of horses and carriages, when travelling was difficult. But it is certainly well worth a visit. The last lingering moments of the twilight hours are the best lime to savour the full power of the coastline s magic; the time when the place comes into its own. The tourists are gone and if you are very lucky you will be alone. A fine circular walk will take you down to the Grand Causeway, past amphitheatres of stone columns and formations. It is not frightening, but there is a power in the place – tangible, yet inexplicable. The blackness of some nights conjure up feelings of eeriness and unease. The visitor realises his place in the scheme of the magnificent spectacle. Once experienced, it is impossible to forget the grandeur of the landscape.

H. Beyond the Causeway, connecting the mainland with an outcrop of rock jutting out of the turbulent Atlantic, is the Carrick-a-Rede Rope Bridge, when first constructed, the bridge was a simple rope handrail with widely spaced slats which was used mainly by salmon fishermen needing to travel from the island to the mainland. In time, the single handrail was replaced with a more sturdy caged bridge, however, it is still not a crossing for the faint- hearted. The Bridge swings above a chasm of rushing, foaming water that seems to drag the unwary- down, and away. Many visitors who make the walk one way are unable to return resulting in them being taken off the island by boat.

TV Addiction

A The amount of time people spend watching television is astonishing. On average, individuals in the industrialized world devote three hours a day to the pursuit – fully half of their leisure time, and more than on any single activity save work and sleep. At this rate, someone who lives to 75 would spend nine years in front of the tube. To some commentators, this devotion means simply that people enjoy TV and make a conscious decision to watch it. But if that is the whole story, why do so many people experience misgivings about how much they view? In Gallup polls in 1992 and 1999, two out of five adult respondents and seven out of 10 teenagers said they spent too much time watching TV. Other surveys have consistently shown that roughly 10 percent of adults calls themselves TV addicts.

B To study people’s reactions to TV, researches have undertaken laboratory experiments in which they have monitored the brain waves (using an electroencephalograph, or EEG) to track behavior and emotion in the normal course of life, as opposed to the artificial conditions of the lab. Participants carried a beeper, and we signaled them six to eight times a day, at random, over the period of a week; whenever they heard the beep, they wrote down what they were doing and how they were feeling using a standardized scorecard.

C As one might expect, people who were watching TV when we beeped them reported feeling relaxed and passive. The EEG studies similarly show less mental stimulation, as measured by alpha brain-wave production, during viewing than during reading. What is more surprising is that the sense of relaxation ends when the set is turned off, but the feelings of passivity and lowered alertness continue. Survey participants say they have more difficulty concentrating after viewing than before. In contrast, they rarely indicate such difficulty after reading. After playing sports or engaging in hobbies, people report improvements in mood. After watching TV, people’s moods are about the same or worse than before. That may be because of viewers’ vague learned sense that they will feel less relaxed if they stop viewing. So they tend not to turn the set-off. Viewing begets more viewing which is the same as the experience of habit-forming drugs. Thus, the irony of TV: people watch a great deal longer than they plan to, even though prolonged viewing is less rewarding. In our ESM studies the longer people sat in front of the set, the less satisfaction they said they derived from it. For some, a twinge of unease or guilt that they aren’t doing something more productive may also accompany and depreciate the enjoyment of prolonged viewing. Researchers in Japan, the U.K. and the U.S. have found that this guilt occurs much more among middle-class viewers than among less affluent ones.

D What is it about TV that has such a hold on us? In part, the attraction seems to spring from our biological ‘orienting response.’ First described by Ivan Pavlov in 1927, the orienting response is our instinctive visual or auditory reaction to any sudden or novel stimulus. It is part of our evolutionary heritage, a built-in sensitivity to movement and potential predatory threats. In 1986 Byron Reeves of Stanford University, Esther Thorson of the University of Missouri and their colleagues began to study whether the simple formal features of television – cuts, edits, zooms, pans, sudden noises – activate the orienting response, thereby keeping attention on the screen. By watching how brain waves were affected by formal features, the researchers concluded that these stylistic tricks can indeed trigger involuntary responses and ‘derive their attentional value through the evolutionary significance of detecting movement… It is the form, not the content, of television that is unique.’

E The natural attraction to television’s sound and the light starts very early in life. Dafna Lemish of Tel Aviv University has described babies at six to eight weeks attending to television. We have observed slightly older infants who, when lying on their backs on the floor, crane their necks around 180 degrees to catch what light through yonder window breaks. This inclination suggests how deeply rooted the orienting response is.

F The Experience Sampling Method permitted us to look closely at most every domain of everyday life: working, eating, reading, talking to friends, playing a sport, and so on. We found that heavy viewers report feeling significantly more anxious and less happy than light viewers do in unstructured situations, such as doing nothing, daydreaming or waiting in line. The difference widens when the viewer is alone. Subsequently, Robert D. McIlwraith of the University of Manitoba extensively studies those who called themselves TV addicts on surveys. On a measure called the Short Imaginal Processes Inventory (SIPI), he found that the self-described addicts are more easily bored and distracted and have poorer attentional control than the non-addicts. The addicts said they used TV to distract themselves from unpleasant thoughts and to fill time. Other studies over the years have shown that heavy viewers are less likely to participate in community activities and sports and are more likely to be obese than moderate viewers or non-viewers.

G More than 25 years ago psychologist Tannis M. MacBeth Williams of the University of British Columbia studied a mountain community that had no television until cable finally arrived. Over time, both adults and children in the town became less creative in problem-solving, less able to persevere at tasks, and less tolerant of unstructured time.

H Nearly 40 years ago Gary A. Steiner of the University of Chicago collected fascinating individual accounts of families whose set had broken. In experiments, families have volunteered or been paid to stop viewing, typically for a week or a month. Some fought, verbally and physically. In a review of these could-turkey studies, Charles Winick of the City University of New York concluded: ‘The first three or four days for most persons were the worst, even in many homes where the viewing was minimal and where there were other ongoing activities. In over half of all the households, during these first few days of loss, the regular routines were disrupted, family members had difficulties in dealing with the newly available time, anxiety and aggressions were expressed…. By the second week, a move toward adaptation to the situation was common.’ Unfortunately, researchers have yet to flesh out these anecdotes; no one has systematically gathered statistics on the prevalence of these withdrawal symptoms.

I Even though TV does seem to meet the criteria for substance dependence, not all researchers would go so far as to call TV addictive. McIlwraith said in 1988 that ‘displacement of other activities by television may be socially significant but still fall short of the clinical requirement of significant impairment.’ He argued that a new category of ‘TV addiction’ may not be necessary if heavy viewing stems from conditions such as depression and social phobia. Nevertheless, whether or not we formally diagnose someone as TV-dependent, millions of people sense that they cannot readily control the amount of television they watch.

Organic Farming and Chemical Fertilisers

A The world’s population continues to climb. And despite the rise of high-tech agriculture, 800 million people don’t get enough to eat. Clearly, it’s time to rethink the food we eat and where it comes from. Feeding 9 billion people will take more than the same old farming practices, especially if we want to do it without felling rainforests and planting every last scrap of prairie. Finding food for all those people will tax farmers’ – and researchers’ – ingenuity to the limit. Yet already, precious aquifers that provide irrigation water for some of the world’s most productive farmlands are drying up or filling with seawater, and arable land in China is eroding to create vast dust storms that redden sunsets as far away as North America. “Agriculture must become the solution to environmental problems in 50 years. If we don’t have systems that make the environment better – not just hold the fort-then we’re in trouble,” says Kenneth Cassman, an agronomist at the University of Nebraska at Lincoln. That view was echoed in January by the Curry report, a government panel that surveyed the future of farming and food in Britain.

B It’s easy to say agriculture has to do better, but what should this friendly farming of the future look like? Concerned consumers come up short at this point, facing what appears to be an ever-widening ideological divide. In one corner are the techno-optimists who put their faith in genetically modified crops, improved agrochemicals and computer-enhanced machinery; in the other are advocates of organic farming, who reject artificial chemicals and embrace back-to-nature techniques such as composting. Both sides cite plausible science to back their claims to the moral high ground, and both bring enough passion to the debate for many people to come away thinking we’re faced with a stark choice between two mutually incompatible options.

C Not so. If you take off the ideological blinkers and simply ask how the world can produce the food it needs with the least environmental cost, a new middle way opens. The key is sustainability: whatever we do must not destroy the capital of soil and water we need to keep on producing. Like today’s organic farming, the intelligent farming of the future should pay much more attention to the health of its soil and the ecosystem it’s part of. But intelligent farming should also make shrewd and locally appropriate use of chemical fertilisers and pesticides. The most crucial ingredient in this new style of agriculture is not chemicals but information about what’s happening in each field and how to respond. Yet ironically, this key element may be the most neglected today.

D Clearly, organic farming has all the warm, fuzzy sentiment on its side. An approach that eschews synthetic chemicals surely runs no risk of poisoning land and water. And its emphasis on building up natural ecosystems seems to be good for everyone. Perhaps these easy assumptions explain why sales of organic food across Europe are increasing by at least 50 per cent per year.

E Going organic sounds idyllic – but it’s native, too. Organic agriculture has its own suite of environmental costs, which can be worse than those of conventional farming, especially if it were to become the world norm. But more fundamentally, the organic versus-chemical debate focuses on the wrong question. The issue isn’t what you put into a farm, but what you get out of it, both in terms of crop yields and pollutants, and what condition the farm is in when you’re done.

F Take chemical fertilisers, which deliver nitrogen, an essential plant nutrient, to crops along with some phosphorus and potassium. It is a mantra of organic farming that these fertilisers are unwholesome, and plant nutrients must come from natural sources. But in fact, the main environmental damage done by chemical fertilisers as opposed to any other kind is through greenhouse gases-carbon dioxide from the fossil fuels used in their synthesis and nitrogen oxides released by their degradation. Excess nitrogen from chemical fertilisers can pollute groundwater, but so can excess nitrogen from organic manures.

G On the other hand, relying solely on chemical fertilisers to provide soil nutrients without doing other things to build healthy soil is damaging. Organic farmers don’t use chemical fertilisers, so they are very good at building soil fertility by working crop residues and manure into the soil, rotating grain with legumes that fix atmospheric nitrogen, and other techniques.

H This generates vital soil nutrients and also creates a soil that is richer in organic matter, so it retains better and is hospitable to the crop’s roots and creatures such as earthworms that help maintain soil fertility. Such soil also holds water better and therefore make more efficient use of both rainfall and irrigation water. And organic matter ties up CO2 in the soil, helping to offset emissions from burning fossil fuels and reduce global warming.

I Advocates of organic farming like to point out that fields managed in this way can produce yields just as high as fields juiced up with synthetic fertilisers. For example, Bill Liebhardt, research manager at the Rodale Institute in Kutztown, Pennsylvania, recently compiled the results of such comparisons for corn, wheat, soybeans and tomatoes in the US and found that the organic fields averaged between 94 and 100 per cent of the yields of nearby conventional crops.

J But this optimistic picture tells only half the story. Farmers can’t grow such crops every year if they want to maintain or build soil nutrients without synthetic fertilisers. They need to alternate with soil-building crops such as pasture grasses and legumes such as alfalfa. So in the long term, the yield of staple grains such as wheat, rice and corn must go down. This is the biggest cost of organic farming. Vaclav Smil of the University of Manitoba in Winnipeg, Canada, estimates that if farmers worldwide gave up the 80 million tonnes of synthetic fertiliser they now use each year, total grain production would fall by at least half. Either farmers would have to double the amount of land they cultivate – at catastrophic cost to natural habitats – or billions of people would starve.

K That doesn’t mean farmers couldn’t get by with less fertiliser. Technologically advanced farmers in wealthy countries, for instance, can now monitor their yields hectare by hectare, or even more finely, throughout a huge field. They can then target their fertiliser to the parts of the field where it will do the most good, instead of responding to average conditions. This increases yield and decreases fertiliser use. Eventually, farmers may incorporate long-term weather forecasts into their planning as well, so that they can cut back on fertiliser use when the weather is likely to make harvests poor anyway, says Ron Olson, an agronomist with Cargill Fertilizer in Tampa, Florida.

L Organic techniques certainly have their benefits, especially for poor farmers. But strict “organic agriculture”, which prohibits certain technologies and allows others, isn’t always better for the environment. Take herbicides, for example. These can leach into waterways and poison both wildlife and people. Just last month, researchers led by Tyrone Hayes at the University of California at Berkeley found that even low concentrations of atrazine, the most commonly used weedkiller in the US, can prevent frog tadpoles from developing properly.

The History of Building Telegraph Lines

A The idea of electrical communication seems to have begun as long ago as 1746 when about 200 monks at a monastery in Paris arranged themselves in a line over a mile long, each holding ends of 25 ft iron wires. The abbot, also a scientist, discharged a primitive electrical battery into the wire, giving all the monks a simultaneous electrical shock. “This all sounds very silly, but is in fact extremely important because, firstly, they all said ‘ow’ which showed that you were sending a signal right along the line; and, secondly, they all said ‘ow’ at the same time, and that meant that you were sending the signal very quickly, “explains Tom Standage, author of the Victorian Internet and technology editor at the Economist. Given a more humane detection system, this could be a way of signaling over long distances.

B With wars in Europe and colonies beyond, such a signaling system was urgently needed. All sorts of electrical possibilities were proposed, some of them quite ridiculous. Two Englishmen, William Cooke and Charles Wheatstone came up with a system in which dials were made to point at different letters, but that involved five wires and would have been expensive to construct.

C Much simpler was that of an American, Samuel Morse, whose system only required a single wire to send a code of dots and dashes. At first, it was imagined that only a few highly skilled encoders would be able to use it but it soon became clear that many people could become proficient in Morse code. A system of lines strung on telegraph poles began to spread in Europe and America.

D The next problem was to cross the sea. Britain, as an island with an empire, led the way. Any such cable to be insulated and the first breakthrough came with the discovery that a rubber-like latex from a tropical tree on the Malay peninsula could do the trick. It was called gutta-percha. The first attempt at a cross channel cable came in 1850. With thin wire and thick installation, it floated and had to be weighed down with a lead pipe.

E It never worked well as the effect of water on its electrical properties was not understood, and it is reputed that a French fisherman hooked out a section and took it home as a strange new form of seaweed. The cable was too big for a single boat so two had to start in the middle of the Atlantic, join their cables and sail in opposite directions. Amazingly, they succeeded in 1858, and this enabled Queen Victoria to send a telegraph message to President Buchanan. However, the 98-word message took more than 19 hours to send and a misguided attempt to increase the speed by increasing the voltage resulted in the failure of the line a week later.

F By 1870, a submarine cable was heading towards Australia. It seemed likely that it would come ashore at the northern port of Darwin from where it might connect around the coast to Queensland and New South Wales. It was an undertaking more ambitious than spanning an ocean. Flocks of sheep had to be driven with the 400 workers to provide food. They needed horses and bullock carts and, for the parched interior, camels. In the north, tropical rains left the teams flooded. In the centre, it seemed that they would die of thirst. One critical section in the red heart of Australia involved finding a route through the McDonnell mountain range and the finding water on the other side.

G The water was not only essential for the construction team. There had to be telegraph repeater stations every few hundred miles to boost the signal and the staff obviously had to have a supply of water. Just as one mapping team was about to give up and resort to drinking brackish water, some aboriginals took pity on them. Altogether, 40,000 telegraph poles were used in the Australian overland wire. Some were cut from trees. Where there were no trees, or where termites ate the wood, steel poles were imported.

H On Thursday, August 22, 1872, the overland line was completed and the first messages could be sent across the continent; and within a few months, Australia was at last in direct contact with England via the submarine cable, too. The line remained in service to bring news of the Japanese attack on Darwin in 1942. It could cost several pounds to send a message and it might take several hours for it to reach its destination on the other side of the globe, but the world would never be the same again. Governments could be in touch with their colonies. Traders could send cargoes based on demand and the latest prices. Newspapers could publish news that had just happened and was not many months old.

Biodiversity

A It seems biodiversity has become a buzzword beloved of politicians, conservationists, protesters and scientists alike. But what exactly is it? The Convention on Biological Diversity, an international agreement to conserve and share the planet’s biological riches, provides a good working definition: biodiversity comprises every form of life, from the smallest microbe to the largest animal or plant, the genes that give them their specific characteristics and the ecosystems of which they are apart.

B In October, the World Conservation Union (also known as the IUCN) published its updated Red List of Threatened Species, a roll call of 11,167 creatures facing extinction – 121 more than when the list was last published in 2000. But the new figures almost certainly underestimate the crisis. Some 1.2 million species of animal and 270,000 species of plant have been classified, but the well-being of only a fraction has been assessed. The resources are simply not available. The IUCN reports that 5714 plants are threatened, for example, but admits that only 4 per cent of known plants has been assessed. And, of course, there are thousands of species that we have yet to discover. Many of these could also be facing extinction.

C It is important to develop a picture of the diversity of life on Earth now so that comparisons can be made in the future and trends identified. But it isn’t necessary to observe every single type of organism in an area to get a snapshot of the health of the ecosystem. In many habitats, there are species that are particularly susceptible to shifting conditions, and these can be used as indicator species.

D In the media, it is usually large, charismatic animals such as pandas, elephants, tigers and whales that get all the attention when a loss of biodiversity is discussed. However, animals or plants far lower down the food chain are often the ones vital for preserving habitats – in the process saving the skins of those more glamorous species. There are known as keystone species.

E By studying the complex feeding relationships within habitats, species can be identified that have a particularly important impact on the environment. For example, the members of the fig family are the staple food for hundreds of different species in many different countries, so important that scientists sometimes call figs “jungle burgers”. A whole range of animals, from tiny insects to birds and large mammals, feed on everything from the tree’s bark and leaves to its flowers and fruits. Many fig species have very specific pollinators. There are several dozen species of the fig tree in Costa Rica, and a different type of wasp has evolved to pollinate each one. Chris Lyle of the Natural History Museum in London – who is also involved in the Global Taxonomy Initiative of the Convention on Biological Diversity – points out that if fig trees are affected by global warming, pollution, disease or any other catastrophe, the loss of biodiversity will be enormous.

F Similarly, sea otters play a major role in the survival of giant kelp forests along the coasts of California and Alaska. These “marine rainforests” provide a home for a wide range of other species. The kelp itself is the main food of purple and red sea urchins and in turn, the urchins are eaten by predators, particularly sea otters. They detach an urchin from the seabed then float to the surface and lie on their backs with the urchin shell on their tummy, smashing it open with a stone before eating the contents. Urchins that are not eaten tend to spend their time in rock crevices to avoid the predators. This allows the kelp to grow – and it can grow many centimetres in a day. As the forests form, bits of kelp break off and fall to the bottom to provide food for the urchins in their crevices. The sea otters thrive hunting for sea urchins in the kelp, and many other fish and invertebrates live among the fronds. The problems start when the sea otter population declines. As large predators they are vulnerable – their numbers are relatively small to disease or human hunters can wipe them out. The result is that the sea urchin population grows unchecked and they roam the seafloor eating young kelp fronds. This tends to keep the kelp very short and stops forests developing, which has a huge impact on biodiversity.

G Conversely, keystone species can also make dangerous alien species: they can wreak havoc if they end up in the wrong ecosystem. The cactus moth, whose caterpillar is a voracious eater of prickly pear was introduced to Australia to control the rampant cacti. It was so successful that someone thought it would be a good idea to introduce it to Caribbean islands that had the same problem. It solved the cactus menace, but unfortunately, some of the moths have now reached the US mainland – borne on winds and in tourists’ luggage – where they are devastating the native cactus populations of Florida.

H Organisations like the Convention on Biological Diversity work with groups such as the UN and with governments and scientists to raise awareness and fund research. A number of major international meetings – including the World Summit on Sustainable Development in Johannesburg this year – have set targets for governments around the world to slow the loss of biodiversity. And the CITES meeting in Santiago last month added several more names to its list of endangered species for which trade is controlled. Of course, these agreements will prove of limited value if some countries refuse to implement them.

I There is cause for optimism, however. There seems to be a growing understanding of the need for sustainable agriculture and sustainable tourism to conserve biodiversity. Problems such as illegal logging are being tackled through sustainable forestry programmes, with the emphasis on minimising the use of rainforest hardwoods in the developed world and on rigorous replanting of whatever trees are harvested. CITES is playing its part by controlling trade in wood from endangered tree species. In the same way, sustainable farming techniques that minimise environmental damage and avoid monoculture.

J Action at a national level often means investing in public education and awareness. Getting people like you and me involved can be very effective. Australia and many European countries are becoming increasingly efficient at recycling much of their domestic waste, for example, preserving natural resources and reducing the use of fossil fuels. This, in turn, has a direct effect on biodiversity by minimising pollution, and an indirect effect by reducing the number of greenhouse gases emitted from incinerators and landfill sites. Preserving ecosystems intact for future generations to enjoy is obviously important, but biodiversity is not some kind of optional extra. Variety may be “the spice of life”, but biological variety is also our life-support system.

What are you laughing at?

A We like to think that laughing is the height of human sophistication. Our big brains let us see the humour in a strategically positioned pun, an unexpected plot twist or a clever piece of wordplay. But while joking and wit are uniquely human inventions, laughter certainly is not. Other creatures, including chimpanzees, gorillas and even rats, chuckle. Obviously, they don’t crack up at Homer Simpson or titter at the boss’s dreadful jokes, but the fact that they laugh in the first place suggests that sniggers and chortles have been around for a lot longer than we have. It points the way to the origins of laughter, suggesting a much more practical purpose than you might think.

B There is no doubt that laughing typical involves groups of people. ‘Laughter evolved as a signal to others – it almost disappears when we are alone,’ says Robert Provine, a neuroscientist at the University of Maryland. Provine found that most laughter comes as a polite reaction to everyday remarks such as ‘see you later’, rather than anything particularly funny. And the way we laugh depends on the company we’re keeping. Men tend to laugh longer and harder when they are with other men, perhaps as a way of bonding. Women tend to laugh more and at a higher pitch when men are present, possibly indicating flirtation or even submission.

C To find the origins of laughter, Provine believes we need to look at the play. He points out that the masters of laughing are children, and nowhere is their talent more obvious than in the boisterous antics, and the original context plays,’ he says. Well-known primate watchers, including Dian Fossey and Jane Goodall, have long argued that chimps laugh while at play. The sound they produce is known as a panting laugh. It seems obvious when you watch their behavior – they even have the same ticklish spots as we do. But remove the context, and the parallel between human laughter and a chimp’s characteristic pant laugh is not so clear. When Provine played a tape of the pant laughs to 119 of his students, for example, only two guessed correctly what it was.

D These findings underline how chimp and human laughter vary. When we laugh the sound is usually produced by chopping up a single exhalation into a series of shorter with one sound produced on each inward and outward breath. The question is: does this pant laughter have the same source as our own laughter? New research lends weight to the idea that it does. The findings come from Elke Zimmerman, head of the Institute for Zoology in Germany, who compared the sounds made by babies and chimpanzees in response to tickling during the first year of their life. Using sound spectrographs to reveal the pitch and intensity of vocalizations, she discovered that chimp and human baby laughter follow broadly the same pattern. Zimmerman believes the closeness of baby laughter to chimp laughter supports the idea that laughter was around long before humans arrived on the scene. What started simply as a modification of breathing associated with enjoyable and playful interactions has acquired a symbolic meaning as an indicator of pleasure.

E Pinpointing when laughter developed is another matter. Humans and chimps share a common ancestor that lived perhaps 8 million years ago, but animals might have been laughing long before that. More distantly related primates, including gorillas, laugh, and anecdotal evidence suggests that other social mammals nay do too. Scientists are currently testing such stories with a comparative analysis of just how common laughter is among animals. So far, though, the most compelling evidence for laughter beyond primates comes from research done by Jaak Panksepp from Bowling Green State University, Ohio, into the ultrasonic chirps produced by rats during play and in response to tickling.

F All this still doesn’t answer the question of why we laugh at all. One idea is that laughter and tickling originated as a way of sealing the relationship between mother and child. Another is that the reflex response to tickling is protective, alerting us to the presence of crawling creatures that might harm us or compelling us to defend the parts of our bodies that are most vulnerable in hand-to-hand combat. But the idea that has gained most popularity in recent years is that laughter in response to tickling is a way for two individuals to signal and test their trust in one another. This hypothesis starts from the observation that although a little tickle can be enjoyable if it goes on too long it can be torture. By engaging in a bout of tickling, we put ourselves at the mercy of another individual, and laughing is a signal that we laughter is what makes it a reliable signal of trust according to Tom Flamson, a laughter researcher at the University of California, Los Angels. ‘Even in rats, laughter, tickle, play and trust are linked. Rats chirp a lot when they play,’ says Flamson. ‘These chirps can be aroused by tickling. And they get bonded to us as a result, which certainly seems like a show of trust.’

G We’ll never know which animal laughed the first laugh, or why. But we can be sure it wasn’t in response to a prehistoric joke. The funny thing is that while the origins of laughter are probably quite serious, we owe human laughter and our language-based humor to the same unique skill. While other animals pant, we alone can control our breath well enough to produce the sound of laughter. Without that control, there would also be no speech – and no jokes to endure.

The reconstruction of community in Talbot Park, Auckland

A. An architecture of disguise is almost complete at Talbot Park in the heart of Auckland’s Glen Innes. The place was once described as a state housing ghetto, rife with crime, vandalism and other social problems. But today after a $48 million urban renewal makeover, the site is home to 700 residents — 200 more than before — and has people regularly inquiring whether they can buy or rent there. “It doesn’t look like social housing,” Housing New Zealand housing services manager Dene Busby says of the tidy brick and weatherboard apartments and townhouses which would look just as much at home in “there is no reason why public housing should look cheap in my view,” says Design Group architect Neil of the eight three-bedroom terrace houses his firm designed.

B. Talbot Park is a triangle of government-owned land bounded by Apirana Ave, Pilkington Rd and Point England Rd. In the early 1960s it was developed for state housing built around a linear park that ran through the middle. Initially, there was a strong sense of a family-friendly community. Former residents recall how the Talbot Park reserve played a big part in their childhoods — a place where the kids in the block came together to play softball, cricket, tiggy, leapfrog and bullrush. Sometimes they’d play “Maoris against Pakehas” but without any animosity. “It was all just good fun”, says Georgie Thompson in Ben Schrader’s We Call it Home: A History of State Housing in New Zealand. “We had respect for our neighbours and addressed them by title Mr. and Mrs. soand-so,” she recalls.

C. Quite what went wrong with Talbot Park is not clear. We call it Home Records that the community began to change in the late 1970s as more Pacific Islanders and Europeans moved in. The new arrivals didn’t readily integrate with the community, a “them and us” mentality developed, and residents interacted with their neighbours less. What was clear was the buildings were deteriorating and becoming dilapidated, petty crime was on the rise and the reserve — focus of fond childhood memories — had become a wasteland and was considered unsafe.

D. But it wasn’t until 2002 that Housing New Zealand decided the properties needed upgrading. The master renewal plan didn’t take advantage of the maximum accommodation density allowable (one unit per 100 sq metres ) but did increase density to one emit per 180 sq m by refurbishing all 108 star flat units, removing the multis and building 111 new home. The Talbot strategy can be summed up as mix, match and manage. Mix up the housing with variety plans from a mix of architects, match house styles to what7 s built by the private sector, match tenants to the mix, and manage their occupancy. Inevitably cost comes into the equation.” If you’re going to build low cost homes, you’ve got to keep them simple and you can’t afford a fancy bit on them. ” says Michael Thompson of Architectus which designed the innovative three level Atrium apartments lining two sides of a covered courtyard. At $300,000 per two bedroom unit, the building is more expensive but provides for independent disabled accommodation as well as offering solar hot water heating and rainwater collection for toilet cisterns and outside taps.

E. The renewal project budget at $1.5 million which will provide park pathways, planting, playgrounds, drinking fountains, seating, skateboard rails, a half-size basketball hard court, and a pavilion. But if there was any doubt this is a low socio-economic area, the demographics for the surrounding Tamaki area are sobering. Of the 5000 households there, 55 percent are state houses, 28 per cent privately owned (compared to about 65 percent nationally) and 17 percent are private rental. The area has a high concentration of households with incomes in the $5000 to $15,000 range and very few with an income over $70,000. That’s in sharp contrast to the more affluent suburbs like Kohimarama and St John’s that surround the area.

F. “The design is for people with different culture background,” says architect James Lunday of Common Ground which designed the 21 large family homes. “Architecturally we decided to be relatively conservative — nice house in its own garden with a bit of space and good indoor outdoor flow.” There’s a slight reflection of the whare and a Pacific fale, but not overplayed “The private sector is way behind in urban design and sustainable futures,” says Bracey. “Redesigning sheets and parks is a big deal and very difficult to do. The private sector won’t do it, because It’s so hard.”

G. There’s no doubt good urban design and good architecture play a significant part in the scheme. But probably more important is a new standard of social control. Housing New Zealand calls it “intensive tenancy management”. Others view it as social engineering. “It’s a model that we are looking at going forward,” according to Housing New Zealand’s central Auckland regional manager Graham Bodman.1 The focus is on frequent inspections, helping tenants to get to know each other and trying to create an environment of respect for neighbours, ” says Bodman. That includes some strict rules — no loud parties after 10 pm, no dogs, no cats in the apartments, no washing hung over balcony rails and a requirement to mow lawns and keep the property tidy. Housing New Zealand has also been active in organising morning teas and sheet barbecues for residents to meet their neighbours. “IVs all based on the intensification,” says Community Renewal project manager Stuart Bracey. “We acknowledge if you are going to put more people living closer together, you have to actually help them to live closer together because it creates tension — especially for people that aren’t used to it.”

The problem of climate change

A. The climate of the Earth is always changing. In the past it has altered as a result of nat­ural causes. Nowadays, however, the term ‘climate change’ is generally used when referring to changes in our climate which have been identified since the early part of the twentieth century. The changes we’ve seen over recent years and those which are predicted to occur over the next 100 years are thought by many to be largely a result of human behavior rather than due to natural changes in the atmosphere. And this is what is so significant about current climactic trends; never before has man played such a significant role in determining long-term weather patterns – we are entering the unknown and there is no precedent for what might happen next.

B The greenhouse effect is very important when we talk about climate change as it relates to the gases which keep the Earth warm. Although the greenhouse effect is a naturally occurring phenomenon, it is believed that the effect could be intensified by human activity and the emission of gases into the atmosphere. It is the extra green­house gases which humans have released which are thought to pose the strongest threat. Certain researchers, such as Dr Michael Crawley, argue: ‘even though this nat­ural phenomenon does exist it is without a doubt human activity that has worsened its effect; this is evident when comparing data regarding the earth’s temperature in the last one hundred years with the one hundred years prior to that.’ Some scientists, however, dispute this as Dr Ray Ellis suggests: ‘human activity may be contributing a small amount to climate change but this increase in temperature is an unavoidable fact based on the research data we have compiled.

C Scientists around the globe are look­ing at all the evidence surrounding climate change and using advanced technology have come up with pre­dictions for our future environment and weather. The next stage of that work, which is just as important, is looking at the knock-on effects of potential changes. For example, are we likely to see an increase in precip­itation and sea levels? Does this mean there will be an increase in flooding and what can we do to protect ourselves from that? How will our health be affected by climate change, how will agricultural practices change and how will wildlife cope? What will the effects on coral be? Professor Max Leonard has suggested, ‘while it may be controversial some would argue that climate change could bring with it positive effects as well as negative ones’.

D There are many institutions around the world whose sole priority is to take action against these environmental problems. Green Peace is the organisation that is probably the most well-known. It is an international organisation that campaigns in favour of researching and promoting solutions to climate change, exposes the companies and governments that are blocking action, lobbies to change national and international policy, and bears witness to the impacts of unnecessary destruction and detrimental human activity.

E The problem of climate change is without a doubt something that this generation and the generations to come need to deal with. Fortunately, the use of renewable energy is becoming increasingly popular, which means that less energy is consumed as renewable energy is generated from natural resources—such as sunlight, wind, rain, tides, and geo­thermal heat—which can be naturally replenished. Another way to help the environment, in terms of climate change, is by travelling light. Walking or riding a bike instead of driv­ing a car uses fewer fossil fuels which release carbon dioxide into the atmosphere. In addi­tion, using products that are made from recycled paper, glass, metal and plastic reduces carbon emissions because they use less energy to manufacture than products made from completely new materials. Recycling paper also saves trees and lets them continue to limit climate change naturally as they remain in the forest, where they remove carbon from the atmosphere. Professor Mark Halton, who has completed various studies in this field, has stated: ‘with all this information and the possible action that we can take, it isn’t too late to save our planet from over-heating and the even worse side-effects of our own activity.

PRIVATE SCHOOLS

Most countries’ education systems have had what you might call educational disasters, but, sadly, in many areas of certain countries these ‘disasters’ are still evident today. The English education system is unique due to the fact that there are still dozens of schools which are known as private schools and they perpetuate privilege and social division. Most countries have some private schools for the children of the wealthy; England is able to more than triple the average number globally. England has around 3,000 private schools and just under half a million children are educated at them whilst some nine million children are educated at state schools. The over­whelming majority of students at private schools also come from middle-class families.

The result of this system is evident and it has much English history embedded within it. The facts seem to speak for themselves. In the private system almost half the students go on to University, whilst in the state sys­tem only about eight per cent make it to further educa­tion. However, statistics such as these can be deceptive due to the fact that middle-class children do better at examinations than working class ones, and most of them stay on at school after 16. Private schools therefore have the advantage over state schools as they are entirely ‘middle class’, and this creates an environment of success where students work harder and apply them­selves more diligently to their school work.

Private schools are extortionately expensive, being as much as £18,000 a year at somewhere such as Harrow or Eton, where Princes William and Harry attended, and at least £8,000 a year almost everywhere else. There are many parents who are not wealthy or even comfortably off but are willing to sacrifice a great deal in the cause of their children’s schooling. It baffles many people as to why they need to spend such vast amounts when there are perfectly acceptable state schools that don’t cost a penny. One father gave his reasoning for sending his son to a private school, ‘If my son gets a five-percent-better chance of going to University then that may be the dif­ference between success and failure.” It would seem to the average person that a £50,000 minimum total cost of second level educa­tion is a lot to pay for a five-percent-better chance. Most children, given the choice, would take the money and spend it on more enjoyable things rather than shelling it out on a school that is too posh for its own good

However, some say that the real reason that parents fork out the cash is prejudice: they don’t want their little kids mixing with the “workers”, or picking up an undesirable accent. In addition to this, it wouldn’t do if at the next din­ner party all the guests were boasting about sending their kids to the same place where the son of the third cousin of Prince Charles is going, and you say your kid is going to the state school down the road, even if you could pocket the money for yourself instead, and, as a result, be able to serve the best Champagne with the smoked salmon and duck.

It is a fact, however, that at many of the best private schools, your money buys you something. One school, with 500 pupils, has 11 science laboratories; another school with 800 pupils, has 30 music practice rooms; another has 16 squash courts, and yet another has its own beach. Private schools spend £300 per pupil a year on invest­ment in buildings and facilities; the state system spends less than £50. On books, the ratio is 3 to 1.

One of the things that your money buys which is difficult to quantify is the appearance of the school, the way it looks. Most private schools that you will find are set in beautiful, well-kept country houses, with extensive grounds and gardens. In comparison with the state schools, they tend to look like castles, with the worst of the state schools looking like public lavatories, perhaps even tiled or covered in graffiti. Many may even have an architectural design that is just about on the level of an industrial shed.

Martin Luther King

A Martin Luther King was born on January 15, 1929, in Atlanta, Georgia. He was the son of the Reverend Martin Luther King, Sr. and Alberta Williams King. He had an older sister, Willie Christine King, and a younger brother Alfred Daniel Williams King. Growing up in Atlanta, King attended Booker T. Washington High School. He skipped ninth and twelfth grade, and entered Morehouse College at age fifteen without formally graduating from high school. From the time that Martin was born, he knew that black people and white people had different rights in certain parts of America. If a black family wanted to eat at a restaurant, they had to sit in a separate section of the restaurant. They had to sit at the back of the cinema, and even use separate toilets. Worse, and perhaps even more humiliating still, in many southern states, if a black man was on a bus and all the seats were taken, he would have to endure the indignity of relinquishing his own seat to a white man. King could never understand the terrible injustice of this.

In 1948, he graduated with a Bachelor of Arts degree in sociology. Later, King began doctoral studies in systematic theology at Boston University and received his Doctor of Philosophy on June 5, 1955. King married Coretta Scott, on June 18, 1953 and they had four children.

B Returning to the South to become pastor of a Baptist Church in Montgomery, Alabama, King first achieved national renown when he helped mobilise the black boycott of the Montgomery bus system in 1955. This was organised after Rosa Parks, a black woman, refused to give up her seat on the bus to a white man – in the segregated south, black people could only sit at the back of the bus. The 382-day boycott led the bus company to change its regulations, and the Supreme Court declared such segrega­tion unconstitutional.

C In 1957 King was active in the organisation of the Southern Leadership Christian Conference (SCLC), formed to co-ordinate protests against discrimination. He advocated non-violent direct action based on the methods of Gandhi, who led protests against British rule in India culminating in India’s independence in 1947. In 1963, King led mass protests against dis­criminatory practices in Birmingham, Alabama, where the white population were violently resisting desegregation. The city was dubbed ‘Bombingham’ as attacks against civil rights protesters increased, and King was arrested and jailed for his part in the protests.

D After his release, King participated in the enormous civil rights march, in Washington, in August 1963, and delivered his famous ‘I have a dream’ speech, predicting a day when the promise of freedom and equality for all would become a reality in America. In 1964 he was awarded the Nobel Peace Prize. In 1965, he led a campaign to register blacks to vote. The same year the US Congress passed the Voting Rights Act out­lawing the discriminatory practices that had barred blacks from voting in the south.

E As the civil rights movement became increasingly radicalised, King found that his message of peaceful protest was not shared by many in the younger generation. King began to protest against the Vietnam War and poverty levels in the US. On March 29, 1968, King went to Memphis, Tennessee, in support of the black sanitary public works employees who had been on strike since March 12 for higher wages and better treat­ment. In one incident, black street repair­men had received pay for two hours when they were sent home because of bad weath­er, but white employees had been paid for the full day. King could not bear to stand by and let such patent acts of racism go unno­ticed. He moved to unite his people, and all the peoples of America on the receiving end of discriminatory practices, to protest for their rights, peacefully but steadfastly.

F On his trip to Memphis, King was booked into room 306 at the Lorraine Motel, owned by Walter Bailey. King was shot at 6:01 p.m. April 4, 1968 while he was standing on the motel’s second-floor balcony. King was rushed to St. Joseph’s Hospital, where doc­tors opened his chest and performed manu­al heart massage. He was pronounced dead at 7:05 p.m. King’s autopsy revealed that although he was only 39 years old, he had the heart of a 60-year-old man.

Maori Fish Hooks

A. Maori fish hooks, made from wood, bone, stone and flax, are intended to have the best possible design and function. The hooks are designed to target specific species with precision. In the industry of commercial long-line fishing, there are some Maori hook designs which are making a splash.

B. When Polynesians first came New Zealand sometime within the years 1100-1300 AD, they didn’t have the technology necessary to heat and manipulate metal out of rocks. Meanwhile, fish was the settlers’ main food source at the time, so fishermen made their hooks and fishing gear out of wood, bone, stone and shells. Other plants native to the island of New Zealand, like as flax (harakeke), cabbage tree (ti) and astelia (kiekie) gave the necessary fibrous material to make fishing lines and nets of greater or equal strength to the jute, which was being used by the Europeans at the time. However, as a material, metal is more malleable, and can be changed into any shape, while natural materials are limited in the shapes they can take on. The Maori fish hooks needed to be more innovative in the ways that they dealt with these limitations.

C. Early accounts of Europeans who settled and explored New Zealand claimed that Maori hooks, known as matau, were “odd”, “of doubtful efficacy”, “very clumsy affairs” or “impossible looking.” Archaeologists from more recent times have also mentioned the round hook appearing as odd, with comments such as, “shaped in a manner which makes it very difficult to imagine could ever be effective in catching a fish.” William Anderson, who was aboard the Resolution during Cook’s third voyage in 1777 as the ship’s surgeon, commented that the Maori “live chiefly by fishing, making use…of wooden fish hooks pointed with bone, but so oddly made that a stranger is at a loss to know how they can answer such a purpose.”

D. The Museum of New Zealand Te Papa Tongarewa did their own recent study on Maori fish hooks two hundred and thirty years later, and were able to demonstrate that the unique hook design was a matter of function. The hook’s design allowed it to catch fish by spinning away from the direction of the point and catching their jaws, instead of poking a hole through the fish or by being used as a lever, which some archaeologists also suggested. It seems that the design of the Maori fish hook is, perhaps, the world’s most efficiently and masterfully designed fish hook, likely superior to any modern metal fish hook of today.

E. To make larger hooks, Maori used shanks made of strong wood, with stout points made of bone or shell. They tied tree branches and saplings together to grow them into the ideal shapes for building, then harvested the plants when they grew to the appropriate size. They hardened wood by carefully drying it and burying underground with fires lit above it. Human bone was often used for bone points, which they lashed securely to a groove at the end of the shank with pre-made flax materials (muka). When they wanted to catch larger species like sharks, groper and ling, they used composite hook. However, average the traditional hook was usually not longer than a three finger breadth (128 mm length).

F. To capture seabirds for food and feathers, like albatross, the islanders used slender hooks which can be differentiated from other hooks intended to catch fish by their lighter build and lack of an inturned point. Many of these hooks were collected by early explorers, suggesting that the taking of seabirds with hook and line was an important source of food and feathers for Maori. (105 mm length). Slender hooks with wide gapes were used to capture albatross and other seabirds for food and feathers, and can be distinguished from hooks intended to catch fish by the lighter construction and lack of an inturned point. Early explorers collected many of these hooks which could indicated that catching seabirds with a hook and line provided significant amounts of food and feathers for the Maori. (105 mm length)

G. Maori adopted new materials quickly once they became available with European explorers, sealers and whalers who began to arrive towards the end of the 1700s. At this point, the Maori were still making their fish hooks, but now using metals and imported materials. Wooden and flax parts of old, abandoned fish hooks decomposed quickly as traditional hooks were cast away in favor of new ones. Tools made of luxury materials such as ivory or greenstone may have been kept around as decorations items, with stylized Maori fish hooks seen today as a symbol of cultural revitalization.

H. The Maori kept recreating traditional designs even as new materials poured in, preferring hook shapes which were introduced by Pakeha into the 1800s. By following the tradition of the rotating hook design, they remained connected with a part of their traditional culture. In the end, though, it was only a matter of time before the amount of mass-produced metal European hooks finally overwhelmed the area, highlighting the difficulty of making hooks from nails, horseshoes and other metal objects, and finally the use of the traditional designs fell out of favor.

I. By the end of the 19th and beginning of the 20th century, tourists and collectors’ demands for Maori artifacts had grown, leading manufacturers to produce large quantities of forged hooks. These replicas were then traded with both Maoris and Europeans to use as forgeries of the real thing, sometimes directly commissioned by artifact dealers themselves. Fake hooks can be spotted by their cheap construction, inconsistent materials, rudimentary lashings, odd or over-elaborate decorative carvings, and finally, by the lack of in-turned points or angled grooves used to actually attach the fishing line.

J. The ways that matau have changed throughout their history is somewhat symbolic of how Maori have adapted to use European tools, materials and technology to their purposes over time, as well as the ways that European influence and technology contributed to, rather overtook, generally compatible Maori skills, and traditional materials were replaced or complemented by metals and, more recently, artificial materials. Commercial longline fishermen everywhere have begun using the circle hook design today, one that is nearly the same as the traditional matau in both its appearance and functionality. It seems that the advantages and improved catch rates of this Maori technology have been recognized once more.

Fossil Files “The Paleobiology Database”

A. Are we now living through the sixth extinction as our own activities destroy ecosystems and wipe out diversity? That’s the doomsday scenario painted by many ecologists, and they may well be right. The trouble is we don’t know for sure because we don’t have a clear picture of how life changes between extinction events or what has happened in previous episodes. We don’t even know how many species are alive today, let alone the rate at which they are becoming extinct. A new project aims to fill some of the gaps. The Paleobiology Database aspires to be an online repository of information about every fossil ever dug up. It is a huge undertaking that has been described as biodiversity’s equivalent of the Human Genome Project. Its organizers hope that by recording the history of biodiversity they will gain an insight into how environmental changes have shaped life on Earth in the past and how they might do so in the future. The database may even indicate whether life can rebound no matter what we throw at it, or whether a human induced extinction could be without parallel, changing the rules that have applied throughout the rest of the planet’s history.

B. But already the project is attracting harsh criticism. Some experts believe it to be seriously flawed. They point out that a database is only as good as the data fed into it, and that even if all the current fossil finds were catalogued, they would provide an incomplete inventory of life because we are far from discovering every fossilised species. They say that researchers should get up from their computers and get back into the dirt to dig up new fossils. Others are more sceptical still, arguing that we can never get the full picture because the fossil record is riddled with holes and biases.

C. Fans of the Paleobiology Database acknowledge that the fossil record will always be incomplete. But they see value in looking for global patterns that show relative changes in biodiversity. “The fossil record is the best tool we have for understanding how diversity and extinction work in normal times,” says John Alroy from the National Center for Ecological Analysis and Synthesis in Santa Barbara. “Having a background extinction estimate gives US a benchmark for understanding the mass extinction that’s currently under way. It allows us to say just how bad it is in relative terms.”

D. To this end, the Paleobiology Database aims to be the most thorough attempt yet to come up with good global diversity curves. Every day between 10 and 15 scientists around the world add information about fossil finds to the database. Since it got up and running in 1998, scientists have entered almost 340,000 specimens, ranging from plants to whales to insects to dinosaurs to sea urchins. Overall totals are updated hourly at www.paleodb.org. Anyone can download data from the public part of the site and play with the numbers to their heart’s content. Already, the database has thrown up some surprising results. Looking at the big picture, Alroy and his colleagues believe they have found evidence that biodiversity reached a plateau long ago, contrary to the received wisdom that species numbers have increased continuously between extinction events. “The traditional view is that diversity has gone up and up and up,” he says. “Our research is showing that diversity limits were approached many tens of millions of years before the dinosaurs evolved, much less suffered extinction.” This suggests that only a certain number of species can live on Earth at a time, filling a prescribed number of niches like spaces in a multi-storey car park. Once it’s full, no more new species can squeeze in, until extinctions free up new spaces or something rare and catastrophic adds a new floor to the car park.

E. Alroy has also used the database to reassess the accuracy of species names. His findings suggest that irregularities in classification inflate the overall number of species in the fossil record by between 32 and 44 per cent. Single species often end up with several names, he says, due to misidentification or poor communication between taxonomists in different countries. Repetition like this can distort diversity curves. “If you have really bad taxonomy in one short interval, it will look like a diversity spike—a big diversification followed by a big extinction-when all that has happened is a change in the quality of names,” says Alroy. For example, his statistical analysis indicates that of the 4861 North American fossil mammal species catalogued in the database, between 24 and 31 per cent will eventually prove to be duplicates.

F. Of course, the fossil record is undeniably patchy. Some places and times have left behind more fossil-filled rocks than others. Some have been sampled more thoroughly. And certain kinds of creatures—those with hard parts that lived in oceans, for example–are more likely to leave a record behind, while others, like jellyfish, will always remain a mystery. Alroy has also tried to account for this. He estimates, for example, that only 41 per cent of North American mammals that have ever lived are known from fossils, and he suspects that a similar proportion of fossils are missing from other groups, such as fungi and insects.

G. Not everyone is impressed with such mathematical wizardry. Jonathan Adrain from the University of Iowa in Iowa City points out that statistical wrangling has been known to create mass extinctions where none occurred. It is easy to misinterpret data. For example, changes in sea level or inconsistent sampling methods can mimic major changes in biodiversity. Indeed, a recent and thorough examination of the literature on marine bivalve fossils has convinced David Jablonsky from the University of Chicago and his colleagues that their diversity has increased steadily over the past 5 million years.

H. With an inventory of all living species, ecologists could start to put the current biodiversity crisis in historical perspective. Although creating such a list would be a task to rival even the Palaeobiology Database, it is exactly what the San Francisco-based ALL Species Foundation hopes to achieve in the next 25 years. The effort is essential, says Harvard biologist Edward o. Wilson, who is alarmed by current rates of extinction. “There is a crisis. We’ve begun to measure it, and it’s very high,” Wilson says. “We need this kind of information in much more detail to protect all of biodiversity, not just the ones we know well.” Let the counting continue.

Decision, Decision !

Research explores when we can make a vital decision quickly and we need to proceed more deliberately

A A widely recognised legend tells us that in Gordium (in what is now Turkey) in the fourth century BC an oxcart was roped to a pole with a complex knot. It was said that the first person to untie it would become the king of Asia. Unfortunately, the knot proved impossible to untie. The story continues that when confronted with this problem, rather than deliberating on how to untie the Gordian knot. Alexander, the famous ruler of the Greeks in the ancient world, simply took out his sword and cut it in two – then went on to conquer Asia. Ever since the notion of a ‘Gordian solution’ has referred to the attractiveness of a simple answer to an otherwise intractable problem.

B Among researchers in the psychology of decision making, however, such solutions have traditionally held little appeal. In particular, the ‘conflict model’ of decision making proposed by psychologists Irving Janis and Leon Mann in their 1977 book, Decision Making, argued that a complex decision-making process is essential for guarding individuals and groups from the peril of ‘group-think’. Decisions made without thorough canvassing, surveying, weighing, examining and reexamining relevant information and options would be suboptimal and often disastrous. One foreign affair decision made by a well-known US political leader in the 1960s is typically held us as an example of the perils of inadequate thought, whereas his successful handling of a water crisis is cited as an example of the advantages of careful deliberation. However, examination of these historical events by Peter Suedfield, a psychologist at the University of British Columbia, and Roderick Kramer, a psychologist at the Stanford Graduate School of Business, found little difference in the two decision-making processes; both crises required and received complex consideration by the political administration, but later only the second one was deemed to be the effective.

C In general, however, organizational and political science offers little evidence that complex decisions fare better than simpler ones. In fact, a growing body of work suggests that in many situations simply ‘snap’ decisions with being routinely superior to more complex ones – an idea that gained widespread public appeal with Malcolm Gladwell’s best-selling book Blink (2005).

D An article by Ap Dijksterhuis of the University of Amsterdam and his colleagues, Making the Right Choice: the Deliberation-without-attention Effect’, runs very much in the spirit of Gladwell’s influential text. Its core argument is that to be effective, conscious (deliberative) decision making requires cognitive resources. Because increasingly complex decisions place increasing strain on those resources, the quality of our decisions declines as their complexity increases. In short, complex decisions overrun our cognitive powers. On the other hand, unconscious decision making (what the author refer to as ‘deliberation without attention’) requires no cognitive resources, so task complexity does not Effectiveness. The seemingly counterintuitive conclusion is that although conscious thought enhances simple decisions, the opposite holds true for more complex decisions.

E Dijksterhuis reports four Simple but elegant studies supporting this argument. In one, participants assessed the quality of four hypothetical cars by considering either four attributes (a simple task) or 12 attributes (a complex task). Among participants who considered four attributes, those who were allowed to engage in undistracted deliberative thought did better at discriminating between the best and worst cars. Those who were distracted and thus unable to deliberate had to rely on their unconscious thinking and did less well. The opposite pattern emerged when people considered 12 criteria. In this case, conscious deliberation led to inferior discrimination and poor decisions.

F In other studies, Dijksterhuis surveyed people shopping for clothes (‘simple’ products) and furniture (‘complex’ products). Compared with those who said they had deliberated long and hard, shoppers who bought with little conscious deliberation felt less happy with their simple clothing purchase but happier with the complex furniture purchases. Deliberation without attention actually produced better results as the decisions became more complex.

G From there, however, the researchers take a big leap. They write: There is no reason to assume that the deliberation-without-attention effect does not generalize to other types of choices – political, managerial or otherwise. In such cases, it should benefit the individual to think consciously about simple matters and to delegate thinking about more complicated matters to the unconscious.

H This radical inference contradicts standard political and managerial theory but doubtless comforts those in politics and management who always find the simple solution to the complex problem an attractive proposition. Indeed, one suspects many of our political leaders already embrace this wisdom.

I Still, it is there, in the realms of society and its governance, that the more problematic implications of deliberation without attention begin to surface. Variables that can be neatly circumscribed in decisions about shopping lose clarity in a world of group dynamics, social interaction, history and politics. Two pertinent questions arise. First, what counts as a complex decision? And second, what counts as a good outcome?

J As social psychologist Kurt Lewin (1890 – 1947) noted, a ‘good’ decision that nobody respects is actually bad, his classic studies of decision making showed that participating in deliberative processes makes people more likely to abide by the results. The issue here is that when political decision-makers make mistakes, it is their politics, or the relationship between their politics and our own, rather than psychology which is at fault.

K Gladwell’s book and Dijksterhuis’s paper are invaluable in pointing out the limitations of the conventional wisdom that decision quality rises with decision-making complexity. But this work still tempts us to believe that decision making is simply a matter of psychology, rather than also a question of politics, ideology and group membership. Avoiding social considerations in a search for general appeal rather than toward it.

Multitasking Debate

A Talking on the phone while driving isn’t the only situation where we’re worse at multitasking than we might like to think we are. New studies have identified a bottleneck in our brains that some say means we are fundamentally incapable of true multitasking. If experimental findings reflect real-world performance, people who think they are multitasking are probably just underperforming in all – or at best, all but one – of their parallel pursuits. Practice might improve your performance, but you will never be as good as when focusing on one task at a time.

B The problem, according to René Marois, a psychologist at Vanderbilt University in Nashville, Tennessee, is that there’s a sticking point in the brain. To demonstrate this, Marois devised an experiment to locate it. Volunteers watch a screen and when a particular image appears, a red circle, say, they have to press a key with their index finger. Different coloured circles require presses from different fingers. Typical response time is about half a second, and the volunteers quickly reach their peak performance. Then they learn to listen to different recordings and respond by making a specific sound. For instance, when they hear a bird chirp, they have to say “ba”; an electronic sound should elicit a “ko”, and so on. Again, no problem. A normal person can do that in about half a second, with almost no effort.

C The trouble comes when Marois shows the volunteers an image, and then almost immediately plays them a sound. Now they’re flummoxed. “If you show an image and play a sound at the same time, one task is postponed,” he says. In fact, if the second task is introduced within the half-second or so it takes to process and react to the first, it will simply be delayed until the first one is done. The largest dual-task delays occur when the two tasks are presented simultaneously; delays progressively shorten as the interval between presenting the tasks lengthens.

D There are at least three points where we seem to get stuck, says Marois. The first is in simply identifying what we’re looking at. This can take a few tenths of a second, during which time we are not able to see and recognise a second item. This limitation is known as the “attentional blink”: experiments have shown that if you’re watching out for a particular event and a second one shows up unexpectedly any time within this crucial window of concentration, it may register in your visual cortex but you will be unable to act upon it. Interestingly, if you don’t expect the first event, you have no trouble to respond to the second. What exactly causes the attentional blink is still a matter for debate.

E A second limitation is in our short-term visual memory. It’s estimated that we can keep track of about four items at a time, fewer if they are complex. This capacity shortage is thought to explain, in part, our astonishing inability to detect even huge changes in scenes that are otherwise identical, so-called “change blindness”. Show people pairs of near-identical photos – say, aircraft engines in one picture have disappeared in the other – and they will fail to spot the differences. Here again, though, there is disagreement about what the essential limiting factor really is. Does it come down to a dearth of storage capacity, or is it about how much attention a viewer is paying?

F A third limitation is that choosing a response to a stimulus – braking when you see a child in the road, for instance, or replying when your mother tells you over the phone that she’s thinking of leaving your dad – also takes brainpower. Selecting a response to one of these things will delay by some tenths of a second your ability to respond to the other. This is called the “response selection bottleneck” theory, first proposed in 1952.

G But David Meyer, a psychologist at the University of Michigan, Ann Arbor, doesn’t buy the bottleneck idea. He thinks dual-task interference is just evidence of a strategy used by the brain to prioritise multiple activities. Meyer is known as something of an optimist by his peers. He has written papers with titles like “Virtually perfect time-sharing in dual-task performance: Uncorking the central cognitive bottleneck”. His experiments have shown that with enough practice – at least 2000 tries – some people can execute two tasks simultaneously as competently as if they were doing them one after the other. He suggests that there is a central cognitive processor that coordinates all this and, what’s more, he thinks it used discretion: sometimes it chooses to delay one task while completing another.

H Marois agrees that practice can sometimes erase interference effects. He has found that with just 1 hour of practice each day for two weeks, volunteers show a huge improvement at managing both his tasks at once. Where he disagrees with Meyer is in what the brain is doing to achieve this. Marois speculates that practice might give us the chance to find less congested circuits to execute a task – rather like finding trusty back streets to avoid heavy traffic on main roads – effectively making our response to the task subconscious. After all, there are plenty of examples of subconscious multitasking that most of us routinely manage: walking and talking, eating and reading, watching TV and folding the laundry.

I It probably comes as no surprise that, generally speaking, we get worse at multitasking as we age. According to Art Kramer at the University of Illinois at Urbana- Champaign, who studies how ageing affects our cognitive abilities, we peak in our 20s. Though the decline is slow through our 30s and on into our 50s, it is there; and after 55, it becomes more precipitous. In one study, he and his colleagues had both young and old participants do a simulated driving task while carrying on a conversation. He found that while young drivers tended to miss background changes, older drivers failed to notice things that were highly relevant. Likewise, older subjects had more trouble paying attention to the more important parts of a scene than young drivers.

J It’s not all bad news for over-55s, though. Kramer also found that older people can benefit from the practice. Not only did they learn to perform better, but brain scans also showed that underlying that improvement was a change in the way their brains become active. While it’s clear that practice can often make a difference, especially as we age, the basic facts remain sobering. “We have this impression of an almighty complex brain,” says Marois, “and yet we have very humbling and crippling limits.” For most of our history, we probably never needed to do more than one thing at a time, he says, and so we haven’t evolved to be able to. Perhaps we will in future, though. We might yet look back one day on people like Debbie and Alun as ancestors of a new breed of true multitaskers.

A decibel Hell (The Effects of Living in a Noisy World)

Section A decibel Hell:

It’s not difficult for a person to encounter sound at levels that can cause adverse health effects. During a single day, people living in a typical urban environment can experience a wide range of sounds in many locations, even once-quiet locales have become polluted with noise. In fact, it’s difficult today to escape sound completely. In its 1999 Guidelines for Community Noise, the World Health Organization (WHO) declared, “Worldwide, noise-induced hearing impairment is the most prevalent irreversible occupational hazard, and it is estimated that 120 million people worldwide have disabling hearing difficulties.” Growing evidence also points to many other health effects of too much volume.

Mark Stephenson, a Cincinnati, Ohio-based senior research audiologist at the National Institute for Occupational Safety and Health (NIOSH), says his agency’s definition of hazardous noise is sound that exceeds the time-weighted average of 85 dBA, meaning the average noise exposure measured over a typical eight-hour workday. Other measures and definitions are used for other purposes.

Section B Growing Volume

In the United States, about 30 million workers are exposed to hazardous sound levels on the job, according to NIOSH. Industries having a high number of workers exposed to loud sounds include construction, agriculture, mining, manufacturing, utilities, transportation, and the military.

Noise in U.S. industry is an extremely difficult problem to monitor, acknowledges Craig Moulton, a senior industrial hygienist for the Occupational Safety and Health Administration (OSHA). “Still,” he says, “OSHA does require that any employer with workers overexposed to noise provide protection for those employees against the harmful effects of noise. Additionally, employers must implement a continuing, effective hearing conservation program as outlined in OSHA’s Noise Standard.”

Section C Scary Sound Effects

Numerous scientific studies over the years have confirmed that exposure to certain levels of sound can damage hearing. Prolonged exposure can actually change the structure of the hair cells in the inner ear, resulting in hearing loss. It can also cause tinnitus, a ringing, roaring, buzzing, or clicking on the ears.

NIOSH studies from the mid to late 1990s show that 90% of coal miners have hearing impairment by age 52 – compared to 9% of the general population – and 70% of male metal/nonmetal miners will experience hearing impairment by age 60 (Stephenson notes that from adolescence onward, females tend to have better hearing than males). Neitzel says nearly half of all construction workers have some degree of hearing loss. “NIOSH research also reveals that by age twenty-five, the average carpenter’s hearing is equivalent to an otherwise healthy fifty-year-old male who hasn’t been exposed to noise,” he says.

William Luxford, medical director of the House Ear Clinic of St. Vincent Medical Center in Los Angeles, points out one piece of good news: “It’s true that continuous noise exposure will lead to the continuation of hearing loss, but as soon as the exposure is stopped, the hearing loss stops. So a change in environment can improve a person’s hearing health.”

Research is catching up with this anecdotal evidence. In the July 2001 issue of Pediatrics, researchers from the Centers for Disease Control and Prevention reported that, based on audiometric testing of 5,249 children as part of the Third National Health and Nutrition, Examination Survey, an estimated 12.5% of American children have noise-induced hearing threshold shifts – or dulled hearing – in one or both ears. Most children with noise-induced hearing threshold shifts have only limited hearing damage, but continued exposure to excessive noise can lead to difficulties with high-frequency sound discrimination. The report listed stereos, music concerts, toys (such as toy telephones and certain rattles), lawnmowers, and fireworks as producing potentially harmful sounds.

Section D Beyond the Ears

The effects of sound don’t stop with the ears. Nonauditory effects of noise exposure are those effects that don’t cause hearing loss but still can be measured, such as elevated blood pressure, loss of sleep, increased heart rate, cardiovascular constriction, labored breathing, and changes in brain chemistry.

The nonauditory effects of noise were noted as early as 1930 in a study published by E.L. Smith and D.L. Laird in volume 2 of the Journal of the Acoustical Society of America. The results showed that exposure to noise caused stomach contractions in healthy human beings. Reports on noise’s nonauditory effects published since that pioneering study have been both contradictory and controversial in some areas.

Bronzaft and the school principal persuaded the school board to have acoustical tile installed in the classrooms adjacent to the tracks. The Transit Authority also treated the tracks near the school to make them less noisy. A follow-up study published in the September 1981 issue of the Journal of Environmental Psychology found that children’s reading scores improved after these interventions were put in place.

Section E Fighting for Quiet

Anti-noise activists say that Europe and several countries in Asia are more advanced than the United States in terms of combating noise. “Population pressure has prompted Europe to move more quickly on the noise issue that the United States has,” Hume says. In the European Union, countries with cities of at least 250,000 people are creating noise maps of those cities to help leaders determine noise pollution policies. Paris has already prepared its first noise maps. The map data, which must be finished by 2007, will be fed into computer models that will help test the sound impact of street designs or new buildings before construction begins.

Activists in other countries say they too want the United States to play a more leading role on the noise issue. But as in other areas of environmental health, merely having a more powerful government agency in place that can set more regulations is not the ultimate answer, according to other experts. Bronzaft stresses that governments worldwide need to increase funding for noise research and do a better job coordinating their noise pollution efforts so they can establish health and environmental policies based on solid scientific research. “Governments have a responsibility to protect their citizens by curbing noise pollution,” she says.

Is Graffiti Art or Crime

A The term graffiti derives from the Italian graffito meaning ‘scratching’ and can be defined as uninvited marking or writing scratched or applied to objects, built structures and natural features. It is not a new phenomenon: examples can be found on ancient structures around the world, in some cases predating the Greeks and Romans. In such circumstances it has acquired invaluable historical and archaeological significance, providing a social history of life and events at that time. Graffiti is now a problem that has become pervasive, as a result of the availability of cheap and quick means of mark-making.

B It is usually considered a priority to remove graffiti as quickly as possible after it appears. This is for several reasons. The first is to prevent ‘copy-cat’ emulation which can occur rapidly once a clean surface is defaced. It may also be of a racist or otherwise offensive nature and many companies and councils have a policy of removing this type of graffiti within an hour or two of it being reported. Also, as paints, glues and inks dry out over time they can become increasingly difficult to remove and are usually best dealt with as soon as possible after the incident. Graffiti can also lead to move serious forms of vandalism and, ultimately, the deterioration of an area, contributing to social decline.

C Although graffiti may be regarded as an eyesore, any proposal to remove it from sensitive historic surfaces should be carefully considered: techniques designed for more robust or utilitarian surfaces may result in considerable damage. In the event of graffiti incidents, it is important that the owners of buildings or other structures and their consultants are aware of the approach they should take in dealing with the problem. The police should be informed as there may be other related attacks occurring locally. An incidence pattern can identify possible culprits, as can stylised signatures or nicknames, known as ‘tags’, which may already be familiar to local police. Photographs are useful to record graffiti incidents and may assist the police in bringing a prosecution. Such images are also required for insurance claims and can be helpful in cleaning operatives, allowing them to see the problem area before arriving on site.

D There are a variety of methods that are used to remove graffiti. Broadly these divide between chemical and mechanical systems. Chemical preparations are based on dissolving the media; these solvents can range from water to potentially hazardous chemical ‘cocktails’. Mechanical systems such as wire-brushing and grit-blasting attempt to abrade or chip the media from the surface. Care should be taken to comply with health and safety legislation with regard to the protection of both passers-by and any person carrying out the cleaning. Operatives should follow product guidelines in terms of application and removal, and wear the appropriate protective equipment. Measures must be taken to ensure that run-off, aerial mists, drips and splashes do not threaten unprotected members of the public. When examining a graffiti incident it is important to assess the ability of the substrate to withstand the prescribed treatment. If there is any doubt regarding this, then small trial areas should be undertaken to assess the impact of more extensive treatment.

E A variety of preventive strategies can be adopted to combat a recurring problem of graffiti at a given site. As no two sites are the same, no one set of protection measures will be suitable for all situations. Each site must be looked at individually. Surveillance systems such as closed-circuit television may also help. In cities and towns around the country, prominently placed cameras have been shown to reduce anti-social behavior of all types including graffiti. Security patrols will also act as a deterrent to prevent recurring attacks. However, the cost of this may be too high for most situations. A physical barriers such as a wall, railings, doors or gates can be introduced to discourage unauthorized access to a vulnerable site. However, consideration has to be given to the impact measures have on the structure being protected. In the worst cases, they can be almost as damaging to the quality of the environment as the graffiti they prevent. In others, they might simply provide a new surface for graffiti.

F One of the most significant problems associated with graffiti removal is the need to remove it from surfaces that are repeatedly attacked. Under these circumstances, the repeated removal of graffiti using even the most gentle methods will ultimately cause damage to the surface material. There may be situations where the preventive strategies mentioned above do not work or are not a viable proposition at a given site. Anti-graffiti coatings are usually applied by brush or spray leaving a thin veneer that essentially serves to isolate the graffiti from the surface.

G Removal of graffiti from a surface that has been treated in this way is much easier, usually using low-pressure water which reduces the possibility of damage. Depending on the type of barrier selected it may be necessary to reapply the coating after each graffiti removal exercise.

Traditional Farming System in Africa

A. By tradition land in Luapula is not owned by individuals, but as in many other parts of Africa is allocated by the headman or headwoman of a village to people of either sex, according to need. Since land is generally prepared by hand, one ulupwa cannot take on a very large area; in this sense land has not been a limiting resource over large parts of the province. The situation has already changed near the main townships, and there has long been a scarcity of land for cultivation in the Valley. In these areas registered ownership patterns are becoming prevalent.

B. Most of the traditional cropping in Luapula, as in the Bemba area to the east, is based on citemene, a system whereby crops are grown on the ashes of tree branches. As a rule, entire trees are not felled, but are pollarded so that they can regenerate. Branches are cut over an area of varying size early in the dry season, and stacked to dry over a rough circle about a fifth to a tenth of the pollarded area. The wood is fired before the rains and in the first year planted with the African cereal finger millet (Eleusine coracana).

C. During the second season, and possibly for a few seasons more the area is planted to variously mixed combinations of annuals such as maize, pumpkins (Telfiria occidentalis) and other cucurbits, sweet potatoes, groundnuts, Phaseolus beans and various leafy vegetables, grown with a certain amount of rotation. The diverse sequence ends with vegetable cassava, which is often planted into the developing last-but-one crop as a relay.

D. Richards (1969) observed that the practice of citemene entails a definite division of labour between men and women. A man stakes out a plot in an unobtrusive manner, since it is considered provocative towards one’s neighbours to mark boundaries in an explicit way. The dangerous work of felling branches is the men’s province, and involves much pride. Branches are stacke by the women, and fired by the men. Formerly women and men cooperated in the planting work, but the harvesting was always done by the women. At the beginning of the cycle little weeding is necessary, since the firing of the branches effectively destroys weeds. As the cycle progresses weeds increase and nutrients eventually become depleted to a point where further effort with annual crops is judged to be not worthwhile: at this point the cassava is planted, since it can produce a crop on nearly exhausted soil. Thereafter the plot is abandoned, and a new area pollarded for the next citemene cycle.

E. When forest is not available – this is increasingly the case nowadays – various ridging systems (ibala) are built on small areas, to be planted with combinations of maize, beans, groundnuts and sweet potatoes, usually relayed with cassava. These plots are usually tended by women, and provide subsistence. Where their roots have year-round access to water tables mango, guava and oil-palm trees often grow around houses, forming a traditional agroforestry system. In season some of the fruit is sold by the roadside or in local markets.

F. The margins of dambos are sometimes planted to local varieties of rice during the rainy season, and areas adjacent to vegetables irrigated with water from the dambo during the dry season. The extent of cultivation is very limited, no doubt because the growing of crops under dambo conditions calls for a great deal of skill. Near towns some of the vegetable produce is sold in local markets.

G. Fishing has long provided a much needed protein supplement to the diet of Luapulans, as well as being the one substantial source of cash. Much fish is dried for sale to areas away from the main waterways. The Mweru and Bangweulu Lake Basins are the main areas of year-round fishing, but the Luapula River is also exploited during the latter part of the dry season. Several previously abundant and desirable species, such as the Luapula salmon or mpumbu (Labeo altivelis) and pale (Sarotherodon machochir) have all but disappeared from Lake Mweru, apparently due to mismanagement.

H. Fishing has always been a far more remunerative activity in Luapula that crop husbandry. A fisherman may earn more in a week than a bean or maize grower in a whole season. I sometimes heard claims that the relatively high earnings to be obtained from fishing induced an ‘easy come, easy go’ outlook among Luapulan men. On the other hand, someone who secures good but erratic earnings may feel that their investment in an economically productive activity is not worthwhile because Luapulans fail to cooperate well in such activities. Besides, a fisherman with spare cash will find little in the way of working equipment to spend his money on. Better spend one’s money in the bars and have a good time!

I. Only small numbers of cattle or oxen are kept in the province owing to the prevalence of the tse-tse fly. For the few herds, the dambos provide subsistence grazing during the dry season. The absence of animal draft power greatly limits peoples’ ability to plough and cultivate land: a married couple can rarely manage to prepare by hand-hoeing. Most people keep freely roaming chickens and goats. These act as a reserve for bartering, but may also be occasionally slaughtered for ceremonies or for entertaining important visitors. These animals are not a regular part of most peoples’ diet.

J. Citemene has been an ingenious system for providing people with seasonal production of high quality cereals and vegetables in regions of acid, heavily leached soils. Nutritionally, the most serious deficiency was that of protein. This could at times be alleviated when fish was available, provided that cultivators lived near the Valley and could find the means of bartering for dried fish. The citemene/fishing system was well adapted to the ecology of the miombo regions and sustainable for long periods, but only as long as human population densities stayed at low levels. Although population densities are still much lower than in several countries of South-East Asia, neither the fisheries nor the forests and woodlands of Luapula are capable, with unmodified traditional practices, of supporting the people in a sustainable manner.

Overall, people must learn to intensify and diversify their productive systems while yet ensuring that these systems will remain productive in the future, when even more people will need food. Increasing overall production offood, though a vast challenge in itself, will not be enough, however. At the same time storage and distribution systems must allow everyone access to at least a moderate share of the total.

Psychology of new product adoption

A In today’s hypercompetitive marketplace, companies that successfully introduce new products are more likely to flourish than those that don’t. businesses spend billions of dollars making better “mousetraps” only to find consumers roundly rejecting them. Studies show that new products fail at the stunning rate of between 40% and 90%, depending on the category, and the odds haven’t changed much in the past 25 years. In the U.S. packaged goods industry, for instance, companies introduce 30,000 products every year, but 70% to 90% of them don’t stay on store shelves for more than 12 months. Most innovative products – those that create new product categories or revolutionize old ones – are also unsuccessful. According to one study, 47% of first movers have failed, meaning that approximately half the companies that pioneered new product categories later pulled out of those businesses.

B After the fact, experts and novices alike tend to dismiss unsuccessful innovations as bad ideas that were destined to fail. Why do consumers fail to buy innovative products even when they offer distinct improvements over existing ones? Why do companies invariably have more faith in new products than is warranted? Few would question the objective advantages of many innovations over existing alternatives, but that’s often not enough for them to succeed. To understand why new products fail to live up to companies’ expectations, we must delve into the psychology of behavior change.

C New products often require consumers to change their behavior. As companies know, those behavior changes entail costs. Consumers costs, such as the activation fees they have to pay when they switch from one cellular service provider to another. They also bear learning costs, such as when they shift from manual to automatic automobile transmissions. People sustain obsolescence costs, too. For example, when they switch from VCRs to DVD players, their videotape collections become useless. All of these are economic switching costs that most companies routinely anticipate.

D What businesses don’t take into account, however, are the psychological costs associated with behavior change. Many products fail because of a universal, but largely ignored, psychological bias: People irrationally overvalue benefits they currently possess relative to those they don’t. The bias leads consumers to value the advantages of products they own more than the benefits of new ones. It also leads executives to value the benefits of innovations they’ve developed over the advantages of incumbent products.

E Companies have long assumed that people will adopt new products that deliver more value or utility than existing ones. Thus, businesses need only to develop innovations that are objectively superior to incumbent products, and consumers will have sufficient incentive to purchase them. In the 1960s, communications scholar Everett Rogers called the concept “relative advantage” and identified it as the most critical driver of new-product adoption. This argument assumes that companies make unbiased assessments of innovations and of consumers, likelihood of adopting them. Although compelling, the theory has one major flaw: It fails to capture the psychological biases that affect decision making.

F In 2002, psychologist Daniel Kahneman won the Nobel Prize in economics for a body of work that explores why and when individuals deviate from rational economic behavior. One of the cornerstones of that research, developed with psychologist Amos Tversky, is how individuals value prospects, or choices, in the marketplace. Kahneman and Tversky showed, and others have confirmed, that human beings’ responses to the alternatives before they have four distinct characteristics.

G First, people evaluate the attractiveness of an alternative based not on its objective, or actual, value but on its subjective, or perceived value. Second, consumers evaluate new products or investments relative to a reference point, usually the products they already own or consume. Third, people view any improvements relative to this reference point as gains and treat all shortcomings as losses. Fourth, and most important, losses have a far greater impact on people than similarly sized gains, a phenomenon that Kahneman and Tversky called “loss aversion.” For instance, studies show that most people will not accept a bet in which there is a 50% chance of winning $100 and a 50% chance of losing $100. The gains from the wager must outweigh the losses by a factor of between two and three before most people find such a bet attractive. Similarly, a survey of 1,500 customers of Pacific Gas and Electric revealed that consumers demand three to four times more compensation to endure a power outage – and suffer a loss – than they are willing to pay to avoid the problem, a potential gain. As Kahneman and Tversky wrote, “losses loom larger than gains.”

H Loss aversion leads people to value products that they already possess – those that are part of their endowment – more than those they don’t have. According to behavioral economist Richard Thaler, consumers value what they own, but many have to give up, much more than they value what they don’t own but could obtain. Thaler called that bias the “endowment effect.”

I In a 1990 paper, Thaler and his colleagues describe a series of experiments they conducted to measure the magnitude of the endowment effect. In one such experiment, they gave coffee mugs to a group of people, the Sellers, and asked at what price point – from 25 cents to $9.25 – the Sellers would be willing to part with those mugs. They asked another group – the Choosers – to whom they didn’t give coffee mugs, to indicate whether they would choose the mug or the money at each price point. In objective terms, all the Sellers and Choosers were in the same situation: They were choosing between a mug and a sum of money. In one trial of this experiment, the Sellers priced the mug at $7.12, on average, but the Choosers were willing to pay only $3.12. In another trial, the Sellers and the Choosers valued the mug at $7.00 and $3.50, respectively. Overall, the Sellers always demanded at least twice as much to give up the mugs as the Choosers would pay to obtain them.

J Kahneman and Tversky’s research also explains why people tend to stick with what they have even if a better alternative exists. In a 1989 paper, economist Jack Knetsch provided a compelling demonstration of what economists William Samuelson and Richard Zeckhauser called the “status quo bias.” Knetsch asked one group of students to choose between an attractive coffee mug and a large bar of Swiss chocolate. He gave a second group of students the coffee mugs but a short time later allowed each student to exchange his or her mug for a chocolate bar. Finally, Knetsch gave chocolate bars to a third group of students but much later allowed each student to exchange his or her bar for a mug. Of the students given a choice at the outset, 56% chose the mug, and 44% chose the chocolate bar, indicating a near even split in preferences between the two products. Logically, therefore, about half of the students to whom Knetsch gave the coffee mug should have traded for the chocolate bar and vice versa. That didn’t happen. Only 11% of the students who had been given the mugs and 10% of those who had been given the chocolate bars wanted to exchange their products. To approximately 90% of the students, giving up what they already had seemed like a painful loss and shrank their desire to trade.

K Interestingly, most people seem oblivious to the existence of the behaviors implicit in the endowment effect and the status quo bias. In study after study, when researchers presented people with evidence that they had irrationally overvalued the status quo, they were shocked, skeptical, and more than a bit defensive. These behavioral tendencies are universal, but awareness of them is not.

Memory Decoding

Try this memory test: Study each face and compose a vivid image for the person’s first and last name. Rose Leo, for example, could be a rosebud and a lion. Fill in the blanks on the next page. The Examinations School at Oxford University is an austere building of oak-paneled rooms, large Gothic windows, and looming portraits of eminent dukes and earls. It is where generations of Oxford students have tested their memory on final exams, and it is where, last August, 34 contestants gathered at the World Memory Championships to be examined in an entirely different manner.

A In timed trials, contestants were challenged to look at and then recite a two-page poem, memorize rows of 40-digit numbers, recall the names of 110 people after looking at their photographs, and perform seven other feats of extraordinary retention. Some tests took just a few minutes; others lasted hours. In the 14 years since the World Memory Championships was founded, no one has memorized the order of a shuffled deck of playing cards in less than 30 seconds. That nice round number has become the four-minute mile of competitive memory, a benchmark that the world’s best “mental athletes,” as some of them like to be called, is closing in on. Most contestants claim to have just average memories, and scientific testing confirms that they’re not just being modest. Their feats are based on tricks that capitalize on how the human brain encodes information. Anyone can learn them.

B Psychologists Elizabeth Valentine and John Wilding, authors of the monograph Superior Memory, recently teamed up with Eleanor Maguire, a neuroscientist at University College London to study eight people, including Karsten, who had finished near the top of the World Memory Championships. They wondered if the contestants’ brains were different in some way. The researchers put the competitors and a group of control subjects into an MRI machine and asked them to perform several different memory tests while their brains were being scanned. When it came to memorizing sequences of three-digit numbers, the difference between the memory contestant and the control subjects was, as expected, immense. However, when they were shown photographs of magnified snowflakes, images that the competitors had never tried to memorize before, the champions did no better than the control group. When the researchers analyzed the brain scans, they found that the memory champs were activating some brain regions that were different from those the control subjects were using. These regions, which included the right posterior hippocampus, are known to be involved in visual memory and spatial navigation.

C It might seem odd that the memory contestants would use visual imagery and spatial navigation to remember numbers, but the activity makes sense when their techniques are revealed. Cooke, a 23-year-old cognitive-science graduate student with a shoulder-length mop of curly hair, is a grand master of brain storage. He can memorize the order of 10 decks of playing cards in less than an hour or one deck of cards in less than a minute. He is closing in on the 30-second deck. In the Lamb and Flag, Cooke pulled out a deck of cards and shuffled it. He held up three cards – the 7 of spades, the queen of clubs, and the 10 of spades. He pointed at a fireplace and said, “Destiny’s Child is whacking Franz Schubert with handbags.” The next three cards were the king of hearts, the king of spades, and the jack of clubs.

D How did he do it? Cooke has already memorized a specific person, verb, and object that he associates with each card in the deck. For example, for the 7 of spades, the person (or, in this case, persons) is always the singing group Destiny’s Child, the action is surviving a storm, and the image is a dinghy. The queen of clubs is always his friend Henrietta, the action is thwacking with a handbag, and the image is of wardrobes filled with designer clothes. When Cooke commits a deck to memory, he does it three cards at a time. Every three-card group forms a single image of a person doing something to an object. The first card in the triplet becomes the person, the second the verb, the third the object. He then places those images along a specific familiar route, such as the one he took through the Lamb and Flag. In competitions, he uses an imaginary route that he has designed to be as smooth and downhill as possible. When it comes time to recall, Cooke takes a mental walk along his route and translates the images into cards. That’s why the MRIs of the memory contestants showed activation in the brain areas associated with visual imagery and spatial navigation.

E The more resonant the images are, the more difficult they are to forget. But even meaningful information is hard to remember when there’s a lot of it. That’s why competitive memorizers place their images along an imaginary route. That technique, known as the loci method, reportedly originated in 477 B.C. with the Greek poet Simonides of Ceos. Simonides was the sole survivor of a roof collapse that killed all the other guests at a royal banquet. The bodies were mangled beyond recognition, but Simonides was able to reconstruct the guest list by closing his eyes and recalling each individual around the dinner table. What he had discovered was that our brains are exceptionally good at remembering images and spatial information. Evolutionary psychologists have offered an explanation: Presumably, our ancestors found it important to recall where they found their last meal or the way back to the cave. After Simonides’ discovery, the loci method became popular across ancient Greece as a trick for memorizing speeches and texts. Aristotle wrote about it, and later a number of treatises on the art of memory were published in Rome. Before printed books, the art of memory was considered a staple of classical education, on a par with grammar, logic, and rhetoric.

F The most famous of the naturals was the Russian journalist S.V. Shereshevski, who could recall long lists of numbers memorized decades earlier, as well as poems, strings of nonsense syllables, and just about anything else he was asked to remember. “The capacity of his memory had no distinct limits,” wrote Alexander Luria, the Russian psychologist who studies Shereshevski also had synesthesia, a rare condition in which the senses become intertwined. For example, every number may be associated with a color or every word with a taste. Synesthetic reactions evoke a response in more areas of the brain, making memory easier.

G K. Anders Ericsson, a Swedish-born psychologist at Florida State University, thinks anyone can acquire Shereshevski’s skills. He cites an experiment with S. F., an undergraduate who was paid to take a standard test of memory called the digit span for one hour a day, two or three days a week. When he started, he could hold, like most people, only about seven digits in his head at any given time (conveniently, the length of a phone number). Over two years, S. F. completed 250 hours of testing. By then, he had stretched his digit span from 7 to more than 80. The study of S. F. led Ericsson to believe that innately superior memory doesn’t exist at all. When he reviewed original case studies of naturals, he found that exceptional memorizers were using techniques – sometimes without realizing it – and lots of practice. Often, exceptional memory was only for a single type of material, like digits. “If we look at some of these memory tasks, they’re the kind of thing most people don’t even waste one hour practicing, but if they wasted 50 hours, they’d be exceptional at it,” Ericsson says. It would be remarkable, he adds, to find a “person who is exceptional across a number of tasks. I don’t think that there’s any compelling evidence that there are such people.”
