Obsessive-compulsive Disorder

Obsessive-compulsive disorder (OCR) is clinically diagnosed as ananxietydisorder and affects up to 4 percent of adults and children. People who suffer from this debilitating disorder have distressing and obsessive thoughts, which usually cause them to performrepetitivebehaviors such as counting silently or washing their hands. Though OCR sufferers understand that their obsessions are unrealistic, they find it stressful to put these intrusive thoughts out of their minds. Those who suffer from obsessive-compulsive disorder develop strict behavioral patterns that become extremely time-consuming and begin to interfere with daily routines. Many people with OCR delay seeking treatment because they are ashamed of their own thoughts and behavior.

OCD sufferers experience worries that are both unreasonable and excessive and that act as a constant source of internal stress. Fear of dirt and contamination are very commonobsessive thoughts. The obsession with orderliness and symmetry is also common. In other cases, persistent thoughts are centered on doubts, such as whether or not a door is locked or a stove is turned off. Impulses, such as the urge to swear in public or to pull a fire alarm, are other types of OCR symptoms. to order to be diagnosed with OCR, a sufferer must exhibit obsessions and/or compulsions that take up a considerable amount of time (at least one hour per day).

To combat excessive thoughts and impulses, most OCR sufferers perform certain repetitive rituals that they believe willrelievetheir anxiety. These compulsions can be either mental or behavioral in nature. Common rituals include excessive checking, washing, counting, and praying. Over time, OCR sufferers attach strict rules to their compulsions. For example, a woman who is obsessed with cleanliness might wash her hands three times before having a meal in order to get the thought of the dirty dishes or silverware out of her mind. However, in many cases, the compulsions aren't related to the obsession at all. A man obsessed with the image of dead animals might count silently up to 500 or touch a specific chair over and over in order to block the images.Holdingonto objects that would normally be discarded, such as newspapers and empty containers, is another common compulsion.

OCR symptoms generally begin between the age of 10 and 24 and continue indefinitely until a person seeks treatment. A child's upbringing does not seem to be part of the cause of the disorder, though stress can make the symptoms stronger. The underlying causes of OCR have been researched greatly and point to a number of different genetic factors. While studies show that OCR and its related anxiety disorders are often passed down through families, the specific symptoms for each family member are rarely the same. For example, a mother who is obsessed with order may have a son who can't stop thinking about a single word or number.

Research on OCR sufferers has found certain physiological trends. In particular, many studies show an overactivity of blood circulation in certain areas of the brain. As a result of this increase in blood flow, the serotoninergic system, which regulates emotions, is unable to function effectively. Studies have also shown that OCR sufferers have less serotonin than the average person. This type of abnormality is also observed in Tourette syndrome and Attention Reficit Hyperactive Disorder. People who developed tics as children are found to be more susceptible to OCR as well. Many reports of OCR point to infections that can trigger the disorder, namely streptococcal infections. It is believed that a case of childhood strep throat can elicit a response from the immune system that produces certain neuropsychiatric disorders, such as OCR.

Because OCR sufferers tend to be so secretive about their symptoms, they often put off treatment for many years. The average OCR sufferer waits about 17 years before receiving medical attention. As with many anxiety disorders, early diagnosis and proper medication can lessen many of the symptoms and allow people to live fairly normal lives. Most treatment plans for OCR involve a combination of medication and psychotherapy. Both cognitive and behavioral therapies are used to teach patients about their disorder and work through the anxiety. Serotonin reuptake inhibitors are prescribed to increase the brain's concentration of serotonin. This medication successfully reduces the symptoms in many OCR sufferers in a short amount of time. For cases when OCR is linked to streptococcal infection,antibiotic therapyis sometimes all that is needed.736

Show Answer-Hide AnswerMaking time for science

Chronobiology might sound a little futuristic like something from a science fiction novel, perhaps but its actually a field of study that concerns one of the oldest processes life on this planet has ever known: short-term rhythms of time and their effect on flora and fauna.

This can take many forms. Marine life, for example, is influenced by tidal patterns. Animals tend to be active or inactive depending on the position of the sun or moon. Numerous creatures, humans included, are largely diurnal that is, they like to come out during the hours of sunlight. Nocturnal animals, such as bats and possums, prefer to forage by night. A third group are known as crepuscular: they thrive in the low-light of dawn and dusk and remain inactive at other hours.

When it comes to humans, chronobiologists are interested in what is known as the circadian rhythm. This is the complete cycle our bodies are naturally geared to undergo within the passage of a twenty-four hour day. Aside from sleeping at night and waking during the day, each cycle involves many other factors such as changes in blood pressure and body temperature. Not everyone has an identical circadian rhythm. Night people, for example, often describe how they find it very hard to operate during the morning, but become alert and focused by evening. This is a benign variation within circadian rhythms known as a chronotype.

Scientists have limited abilities to create durable modifications of chronobiological demands. Recent therapeutic developments for humans such as artificial light machines and melatonin administration can reset our circadian rhythms, for example, but our bodies can tell the difference and health suffers when we breach these natural rhythms for extended periods of time. Plants appear no more malleable in this respect; studies demonstrate that vegetables grown in season and ripened on the tree are far higher in essential nutrients than those grown in greenhouses and ripened by laser.

Knowledge of chronobiological patterns can have many pragmatic implications for our day-to-day lives. While contemporary living can sometimes appear to subjugate biology after all, who needs circadian rhythms when we have caffeine pills, energy drinks, shift work and cities that never sleep? keeping in synch with our body clock is important.

The average urban resident, for example, rouses at the eye-blearing time of 6.04 a.m., which researchers believe to be far too early. One study found that even rising at 7.00 a.m. has deleterious effects on health unless exercise is performed for 30 minutes afterward. The optimum moment has been whittled down to 7.22 a.m.; muscle aches, headaches and moodiness were reported to be lowest by participants in the study who awoke then.

Once youre up and ready to go, what then? If youre trying to shed some extra pounds, dieticians are adamant: never skip breakfast. This disorients your circadian rhythm and puts your body in starvation mode. The recommended course of action is to follow an intense workout with a carbohydrate-rich breakfast; the other way round and weight loss results are not as pronounced.

Morning is also great for breaking out the vitamins. Supplement absorption by the body is not temporal-dependent, but naturopath Pam Stone notes that the extra boost at breakfast helps us get energised for the day ahead. For improved absorption, Stone suggests pairing supplements with a food in which they are soluble and steering clear of caffeinated beverages. Finally, Stone warns to take care with storage; high potency is best for absorption, and warmth and humidity are known to deplete the potency of a supplement.

After-dinner espressos are becoming more of a tradition we have the Italians to thank for that but to prepare for a good nights sleep we are better off putting the brakes on caffeine consumption as early as 3 p.m. With a seven hour half-life, a cup of coffee containing 90 mg of caffeine taken at this hour could still leave 45 mg of caffeine in your nervous system at ten oclock that evening. It is essential that, by the time you are ready to sleep, your body is rid of all traces.

Evenings are important for winding down before sleep; however, dietician Geraldine Georgeou warns that an after-five carbohydrate-fast is more cultural myth than chronobiological demand. This will deprive your body of vital energy needs. Overloading your gut could lead to indigestion, though. Our digestive tracts do not shut down for the night entirely, but their work slows to a crawl as our bodies prepare for sleep. Consuming a modest snack should be entirely sufficient.

Introducing dung1 beetles into a pasture is a simple process: approximately 1,500 beetles

are released, a handful at a time, into fresh cow pats2 in the cow pasture. The beetles

immediately disappear beneath the pats digging and tunnelling and, if they successfully

adapt to their new environment, soon become a permanent, self-sustaining part of the

local ecology. In time they multiply and within three or four years the benefits to the

pasture are obvious.

Dung beetles work from the inside of the pat so they are sheltered from predators such

as birds and foxes. Most species burrow into the soil and bury dung in tunnels directly

underneath the pats, which are hollowed out from within. Some large species originating

from France excavate tunnels to a depth of approximately 30 cm below the dung pat.

These beetles make sausage-shaped brood chambers along the tunnels. The shallowest

tunnels belong to a much smaller Spanish species that buries dung in chambers that hang

like fruit from the branches of a pear tree. South African beetles dig narrow tunnels of

approximately 20 cm below the surface of the pat. Some surface-dwelling beetles,

including a South African species, cut perfectly-shaped balls from the pat, which are

rolled away and attached to the bases of plants.

For maximum dung burial in spring, summer and autumn, farmers require a variety of

species with overlapping periods of activity. In the cooler environments of the state of

Victoria, the large French species (2.5 cms long), is matched with smaller (half this size),

temperate-climate Spanish species. The former are slow to recover from the winter cold

and produce only one or two generations of offspring from late spring until autumn. The

latter, which multiply rapidly in early spring, produce two to five generations annually.

The South African ball-rolling species, being a sub-tropical beetle, prefers the climate of

northern and coastal New South Wales where it commonly works with the South African

tunneling species. In warmer climates, many species are active for longer periods of the

year.

Academic Reading sample task Identifying information

A There are now over 700 million motor vehicles in the

world - and the number is rising by more than 40 million

each year. The average distance driven by car users is

growing too - from 8km a day per person in western Europe

in 1965 to 25 km a day in 1995. This dependence on motor

vehicles has given rise to major problems, including

environmental pollution, depletion of oil resources,

traffic congestion and safety.

B While emissions from new cars are far less harmful than

they used to be, city streets and motorways are becoming

more crowded than ever, often with older trucks, buses

and taxis which emit excessive levels of smoke and fumes.

This concentration of vehicles makes air quality in urban

areas unpleasant and sometimes dangerous to breathe.

Even Moscow has joined the list of capitals afflicted by

congestion and traffic fumes. In Mexico City, vehicle

pollution is a major health hazard.

C Until a hundred years ago, most journeys were in the 20km

range, the distance conveniently accessible by horse.

Heavy freight could only be carried by water or rail.

Invention of the motor vehicle brought personal mobility

to the masses and made rapid freight delivery possible

over a much wider area. In the United Kingdom, about 90

per cent of inland freight is carried by road. The world

cannot revert to the horse-drawn wagon. Can it avoid

being locked into congested and polluting ways of

transporting people and goods?

D In Europe most cities are still designed for the old

modes of transport. Adaptation to the motor car has

involved adding ring roads, one-way systems and parking

lots. In the United States, more land is assigned to car

use than to housing. Urban sprawl means that life

without a car is next to impossible. Mass use of motor

vehicles has also killed or injured millions of people.

Other social effects have been blamed on the car such as

alienation and aggressive human behaviour.

E A 1993 study by the European Federation for Transport and

Environment found that car transport is seven times as

costly as rail travel in terms of the external social

costs it entails - congestion, accidents, pollution, loss

of cropland and natural habitats, depletion of oil

resources, and so on. Yet cars easily surpass trains or Academic Reading sample task Identifying information

buses as a flexible and convenient mode of personal

transport. It is unrealistic to expect people to give up

private cars in favour of mass transit.Technical solutions can reduce the pollution problem and

increase the fuelled efficiency of engines. But fuel

consumption and exhaust emissions depend on which cars

are preferred by customers and how they are driven. Many

people buy larger cars than they need for daily purposes

or waste fuel by driving aggressively. Besides, global

car use is increasing at a faster rate than the

improvement in emissions and fuel efficiency which

technology is now making possible.

G Some argue that the only long-term solution is to design

cities and neighbourhoods so that car journeys are not

necessary - all essential services being located within

walking distance or easily accessible by public

transport. Not only would this save energy and cut

carbon dioxide emissions, it would also enhance the

quality of community life, putting the emphasis on people

instead of cars. Good local government is already

bringing this about in some places. But few democratic

communities are blessed with the vision and the capital

to make such profound changes in modern lifestyles.

H A more likely scenario seems to be a combination of mass

transit systems for travel into and around cities, with

small low emission cars for urban use and larger hybrid

or lean burn cars for use elsewhere. Electronically

tolled highways might be used to ensure that drivers pay

charges geared to actual road use. Better integration of

transport systems is also highly desirable - and made

more feasible by modern computers. But these are

solutions for countries which can afford them. In most

developing countries, old cars and old technologies

continue to predominateStaff trainingStaff training is verybeneficialfor companies but some staff still remain unconvinced. This is a difference in beliefs between departments aboutthe generaleffectiveness of training. Our company goal has always been to integrate consistent training into all our departments because it creates a more favourable environment in which to work. In fact, we have been rated as the industrys number five work place solely on the basis of our positive and encouraging company culture, much of which is connected to staff development.

Motivationis a common reason for providing training. Our board of directors have always believed thatjob satisfactionand happy staff who enjoy their job should work better and more efficiently than unsatisfied employees. Problems of unmotivated or even demotivated staff are common in the current economic climate as many fear redundancy or have no hope of promotion. Therefore, we continue to invest in growth opportunities and internal promotion.

Technologyrepresents another rational behind our staff training.New computers, networks and evolving working habits all need to be explained to new and existing staff alike. Nevertheless, time for training seems scarce and as a result certified online courses are being introduced at all levels due to their flexibility.Online language courseshave increased in popularity with employees who can study online at lunch or after work.Mobile internet accessalso means we can now offer employee training 24 hours a day.

Not allemployerssupport staff training. There are valid reasons for a lack of stafftraining departments. HR company Guptar associates revealed that a substantial percentage of both in-house and out-house training is actually unproductive. As an alternative they propose moreeffective trainingwith specific measurable goals as opposed to more qualitative and hard to assess personal improvement aims. They additionally point to the need for whole team involvement from the top of the department all the way down to theshop floor. We have taken this onboard and are devising new courses to be offered on a larger scale.

Training has become a largemarketas greater numbers of companiesoutsourceto training experts. One important fact that remains is that it is still on the bottom of most managers priorities, possibly in fear ofhighly trainedemployees who have received expensive training resigning and taking their expensive skills with them. To tackle both these issues we have started a mentoring system for new staff which brings larger benefits than external trainers and coupled with our online training provides a more effective solution with lower costs. As a result, we no longer need to tie employees to the company with set contracts to recover training costs.

This part of the test should take 17 -20 minutesWhat is music?A.Music has probably existed for as long as man has been human, and it certainly predates civilization by tens of millenia. Yet even today there is no clear definition of exactly what music is. For example, birdsong is certainly melodic, but it is not tuneful, and it is not created with the intention of being musical (in fact it is sometimes meant to sound threatening) - therefore does it count as music?

B.On the other hand, some modern composers have been challenging the idea that music should be arranged in a pleasant manner with the notes falling in an orderly succession. Others, famously the avant guarde composer John Cage have even used silence and called the result music. As a result there is no one definition of music. Perhaps it should be said that music, like beauty, is what the person who sees or hears it believes it to be.

C.Music is divided in many ways. Music itself is split into notes, clefts, quavers, and semi-demi quavers. Ancient and medieval musicologists believed that these notes could be arranged 'horizontally' into melody (making notes that match on the same scale) and 'vertically' (going up and down the scales to create harmony). Another very basic measurement of music is the 'pulse'. This is present in almost all forms of music, and is particularly strong in modern popular music. The pulse is the regular beat which runs through a tune. When you tap your foot or clap your hands in time to a song, you are beating out the pulse of that song.

D.Another way of dividing music is by genre. Even a child who does not know that (for example) rock and roll and classical music are different genres will be instantly aware that these are very different sounds; though he will not be aware that one is a percussion-led melody while the other emphasizes harmony over rhythm and timbre. Each genre of music has numerous sub-divisions. Classical music is divided by type - for example symphonies, concertos and operas, and by sub-genre, for example baroque and Gregorian chant. Just to make it more fun, modern musicians have also been experimenting with crossover music, so that we get Beatles tunes played by classical orchestras, and groups like Queen using operatic themes in songs such as 'Bohemian rhapsody'.

E.Almost all music is a collaboration between the composer, and the performer, while song requires a lyricist to write the words as well. Sometimes old tunes are adapted for new lyrics - for example the song 'Happy Birthday' is based on a tune originally called 'Have a nice Day'. At other times a performer might produce a song in a manner which the original composer would not recognize. (A famous example is the punk rock band the Sex Pistols performing the British national anthem 'God save the Queen'.)

F.This is because the composer and lyricist have to leave the performer some freedom to perform in the way that suits him or her best. While many classical compositions have notes stressing how a piece should be performed (for example a piece played 'con brio' should be light and lively) in the end, what the listener hears is the work of the performer. Jazz music has fully accepted this, and jazz performers are not only expected to put their own interpretation on a piece, but are expected to play even the same piece with some variation every time.

G.Many studies of music do not take into account where the music is to be played and who the audience will be. This is a major mistake, as the audience is very much a part of the musical experience. Any jazz fan will tell you that jazz is best experienced in small smoky bars some time after midnight, while a classical fan will spend time and money making sure that the music on his stereo comes as close as possible to the sound in a large concert hall. Some music, such as dance music, is designed to be interactive, while other music is designed to remain in the background, smoothing out harsh sounds and creating a mood. This is often the case with cinema music - this powerfully changes the mood of the audience, yet remains so much in the background that many cinemagoers are unaware that the music is actually playing.

H.Music is very much a part of human existence, and we are fortunate today in having music of whatever kind we choose instantly available at the touch of a button. Yet spare a thought for those who still cannot take advantage of this bounty. This includes not only the deaf, but those people who are somehow unable to understand or recognize music when they hear it. A famous example is United President Ulysses Grant, who famously said 'I can recognise two tunes. One is 'Yankee doodle' and the other one isn't.'

Choose which of these sentences is closest to the meaning in the text.

1. Modern composers do not always want their music to sound pleasantSome modern composers do not want their music to be enjoyableA modern musical composition should not be orderly2. Crossover music is when classical orchestras play modern tunesCrossover music moves between musical genresCrossover music is a modern musical genre

Zoo Conservation Programmes

One ofLondonZoos recent advertisements caused me some irritation, so patently did it distort reality. Headlined Without zoos you might as well tell these animals to get stuffed, it was bordered with illustrations of severalendangered speciesand went on to extol the myth that without zoos like London Zoo these animals will almost certainly disappear forever. With thezoo worlds rather mediocre record on conservation, one might be forgiven for being slightly skeptical about such an advertisement.

Zoos were originally created as places of entertainment, and their suggested involvement with conservation didnt seriously arise until about 30 years ago, when theZoological Societyof London held the first formal international meeting on the subject. Eight years later, a series of world conferences took place, entitled The Breeding of Endangered Species, and from this point onwards conservation became the zoo communitys buzzword. This commitment has now been clear defined in The World ZpoConservation Strategy(WZGS, September 1993), which although an important and welcome document does seem to be based on an unrealistic optimism about the nature of the zoo industry.

The WZCS estimates that there are about 10,000 zoos in the world, of which around 1,000 represent acoreof quality collections capable of participating in co-ordinated conservationprogrammes. This is probably the documents first failing, as I believe that 10,000 is a serious underestimate of the total number of places masquerading as zoological establishments. Of course it is difficult to getaccurate databut, to put the issue into perspective, I have found that, in a year of working in Eastern Europe, I discover fresh zoos on almost a weekly basis.

The second flaw in the reasoning of the WZCS document is the naive faith it places in its 1,000 core zoos. One would assume that the calibre of these institutions would have been carefully examined, but it appears that the criterion for inclusion on this select list might merely be that the zoo is a member of a zoo federation or association. This might be a goodstarting point, working on the premise that members must meet certain standards, but again the facts dont support the theory. The greatly respectedAmerican Associationof Zoological Parks and Aquariums (AAZPA) has had extremely dubious members, and in the UK the Federation of Zoological Gardens of Great Britain and Ireland has

Occasionally had members that have been roundly censured in the national press. These includeRobin HillAdventure Parkon theIsle of Wight, which many considered the most notorious collection of animals in the country. This establishment, which for years was protected by the Isles local council (which viewed it as a tourist amenity), was finally closed down following a damning report by a veterinary inspector appointed under the terms of the Zoo Licensing Act 1981. As it was always a collection of dubious repute, one is obliged to reflect upon the standards that the Zoo Federation sets when granting membership. The situation is even worse in developing countries where little money is available for redevelopment and it is hard to see a way of incorporating collections into the overall scheme of the WZCS.

Even assuming that the WZCSs 1,000 core zoos are all of a high standard complete with scientific staff and research facilities, trained and dedicated keepers, accommodation that permits normal or natural behaviour, and a policy of co-operating fully with one another what might be the potential for conservation? Colin Tudge, author of Last Animals at the Zoo (Oxford University Press, 1992), argues that if the worlds zoos worked together in co-operative breeding programmes, then even without further expansion they could save around 2,000 species of endangered land vertebrates. This seems an extremely optimistic proposition from a man who must be aware of the failings and weaknesses of the zoo industry the man who, when a member of the council of London Zoo, had to persuade the zoo to devote more of its activities to conservation. Moreover, where are the facts to support such optimism?

Today approximately 16 species might be said to have been saved by captive breeding programmes, although a number of these can hardly be looked upon as resounding successes. Beyond that, about a further 20 species are being seriously considered for zoo conservation programmes. Given that the international conference at London Zoo was held 30 years ago, this is pretty slow progress, and a long way off Tudges target of 2,000.

A Workaholic EconomyFor The first century or so of theindustrialrevolution,increased productivityled to decreases in working hours. Employees who had been putting in 12-hour days, six days a week, found their time on the job shrinking to 10 hours daily, then, finally, to eight hours, five days a week. Only a generation ago social planners worried about what people would do with all this new-found free time. In the US, at least, it seems they need not have bothered.

Although theoutputper hour of work has more than doubled since 1945, leisure seems reserved largely for the unemployed and underemployed. Those who work full-time spend as much time on the job as they did at the end ofWorld WarII. In fact,working hourshave increased noticeably since 1970 perhaps because real wages have stagnated since that year. Bookstores now abound with manuals describing how to manage time andcope with stress.

There are several reasons for lost leisure. Since 1979, companies have responded to improvements in thebusiness climateby having employees work overtime rather than by hiring extra personnel, says economist Juliet B. Schor of Harvard University. Indeed, the current economic recovery has gained a certain amount of notoriety for its jobless nature: increased production has been almost entirely decoupled from employment. Some firms are even downsizing as their profits climb. All things being equal, we'd be better off spreading around the work, observes labour economist Ronald G. Ehrenberg of Cornell University.

Yet ahostof factors pushes employers to hire fewer workers for more hours and, at the same time, compels workers to spend more time on the job. Most of those incentives involve what Ehrenberg calls the structure of compensation: quirks in the way salaries and benefits are organised that make it more profitable to ask 40 employees to labour an extra hour each than to hire one more worker to do the same 40-hour job.

Professional and managerial employees supply the most obvious lesson along these lines. Once people are on salary, their cost to a firm is the same whether they spend 35 hours a week in theofficeor 70. Diminishing returns may eventually set in as overworked employees lose efficiency or leave for more arable pastures. But in the short run, the employers incentive is clear. Evenhourly employeesreceive benefits -such aspension contributionsandmedical insurance- that are not tied to the number of hours they work. Therefore, it is more profitable for employers to work their existing employees harder.

For all that employees complain aboutlong hours, they, too, have reasons not totrade moneyfor leisure. People who work reduced hours pay a huge penalty in career terms, Schor maintains. It's taken as a negative signal about their commitment to the firm. [Lotte] Bailyn [of Massachusetts Institute of Technology] adds that many corporate managers find it difficult to measure the contribution of their underlings to a firms well-being, so they use the number of hours worked as a proxy for output. Employees know this, she says, and they adjust their behavior accordingly.

Although the image of the good worker is the one whose life belongs to the company, Bailyn says, it doesn't fit the facts. She cites both quantitative and qualitative studies that show increased productivity for part-time workers: they make better use of the time they have, and they are less likely to succumb to fatigue in stressful jobs. Companies that employ more workers for less time also gain from the resulting redundancy, she asserts. The extra people can cover the contingencies that you know are going to happen, such as when crises take people away from the workplace. Positive experiences with reduced hours have begun to change the more-is-better culture at some companies, Schor reports.

Larger firms, in particular, appear to be more willing to experiment with flexible working arrangements...

It may take even more than changes in the financial and cultural structures of employment for workers successfully to trade increased productivity andmoneyfor leisure time, Schor contends. She says the U.S. market for goods has become skewed by the assumption of full-time, two-careerhouseholds. Automobile makers no longer manufacture cheap models, and developers do not build the tiny bungalows that served the first postwar generation of home buyers. Not even the humblest household object is made without a microprocessor. As Schor notes, the situation is a curious inversion of the appropriate technology vision that designers have had for developing countries: U.S. goods are appropriate only for high incomes and long hours. ----- Paul WalluhQuestions 27-32Do the following statements agree with the views of the writer in reading passage 4?

Alarming rate of loss of tropical rainforests

Adults andchildrenare frequently confronted with statements about the alarming rate of loss oftropical rainforests.For example, onegraphic illustrationto which children might readily relate is the estimate that rainforests are being destroyed at a rate equivalent to one thousand football fields every forty minutes about the duration of a normal classroom period. In the face of the frequent and often vividmedia coverage, it is likely that children will have formed ideas about rainforests what and where they are, why they are important, what endangers them independent of any formal tuition. It is also possible that some of these ideas will be mistaken. Many studies have shown that children harbour misconceptions about pure, curriculum science. These misconceptions do not remain isolated but become incorporated into a multifaceted, but organised, conceptual framework, making it and the component ideas, some of which are erroneous, more robust but also accessible to modification. These ideas may be developed by children absorbing ideas through the popular media. Sometimes this information may be erroneous. It seems schools may not be providing an opportunity for children to re-express their ideas and so have them tested and refined by teachers and their peers.

Despite the extensive coverage in the popular media of the destruction ofrainforests, little formal information is availableabout childrens ideas in this area. The aim of the present study is to start to provide such information, to help teachers design their educational strategies to build upon correct ideas and to displace misconceptions and to plan programmes in environmental studies in their schools.

The studysurveyschildrensscientific knowledgeand attitudes to rainforests. Secondaryschool childrenwere asked to complete a questionnaire containing five open-form questions. The most frequent responses to the first question were descriptions which are self-evident from the term rainforest. Some children described them as damp, wet or hot. The second question concerned the geographical location of rainforests. The commonest responses were continents or countries: Africa (given by 43% of children), South America (30%), Brazil (25%). Some children also gave more general locations, such as being near the Equator.

Responses to question three concerned the importance of rainforests. The dominant idea, raised by 64% of the pupils, was that rainforests provide animals with habitats. Fewerstudentsresponded that rainforests provide plant habitats, and even fewer mentioned the indigenous populations of rainforests. More girls (70%) than boys (60%) raised the idea of rainforest as animal habitats.

Similarly, but at alower level, more girls (13%) than boys (5%) said that rainforests provided human habitats. These observations are generally consistent with our previous studies of pupils views about the use and conservation of rainforests, in which girls were shown to be more sympathetic to animals and expressed views which seem to place an intrinsic value on non-human animal life.

The fourth question concerned the causes of the destruction of rainforests. Perhaps encouragingly, more than half of the pupils (59%) identified that it is human activities which are destroying rainforests, some personalising the responsibility by the use of terms such as we are. About 18% of the pupils referred specifically to logging activity.

One misconception, expressed by some 10% of the pupils, was that acid rain is responsible for rainforest destruction; a similar proportion said that pollution is destroying rainforests. Here, children are confusing rainforest destruction with damage to the forests of Western Europe by these factors. While two fifths of the students provided the information that the rainforests provide oxygen, in some cases this response also embraced the misconception that rainforest destruction would reduce atmospheric oxygen, making the atmosphere incompatible with human life on Earth.

In answer to the final question about the importance of rainforest conservation, the majority of children simply said that we need rainforests to survive. Only a few of the pupils (6%) mentioned that rainforest destruction may contribute to global warming. This is surprising considering the high level of media coverage on this issue. Some children expressed the idea that the conservation of rainforests is not important.

The results of this study suggest that certainideaspredominate in the thinking of children about rainforests. Pupils responses indicate some misconceptions in basic scientific knowledge of rainforests ecosystems such as their ideas about rainforests as habitats for animals, plants and humans and the relationship between climatic change and destruction of rainforests.

Pupils did not volunteer ideas that suggested that they appreciated the complexity of causes of rainforest destruction. In other words, they gave no indication of an appreciation of either the range of ways in which rainforests are important or the complex social, economic and political factors which drive the activities which are destroying the rainforests. One encouragement is that the results of similar studies about other environmental issues suggest that older children seem to acquire the ability to appreciate, value and evaluate conflicting views. Environmental education offers an arena in which these skills can be developed, which is essential for these children as future decision-makers.

Changing OurUnderstanding of HealthAThe concept of health holds different meanings for different people and groups. These meanings of health have also changed over time. This change is no moreevidentthan in Western society today, when notions of health and health promotion are being challenged and expanded innew ways.

BFor much of recent Western history, health has been viewed in the physical sense only. That is,good healthhas been connected to the smooth mechanical operation of the body, while ill health has been attributed to a breakdown in this machine. Health in this sense has been defined as the absence of disease or illness and is seen in medical terms. According to this view, creating health for people means providing medical care to treat or prevent disease and illness. During this period, there was an emphasis on providing clean water, improved sanitation and housing.

CIn the late 1940s theWorld Health Organisationchallenged this physically and medically oriented view of health. They stated that 'health is a complete state of physical, mental and social well-being and is not merely the absence of disease' (WHO, 1946). Health and the person were seen more holistically (mind/body/spirit) and not just in physical terms.

DThe 1970s was a time of focusing on theprevention of diseaseand illness by emphasising the importance of the lifestyle and behaviour of the individual. Specific behaviours which were seen to increase risk of disease, such as smoking, lack of fitness and unhealthy eating habits, were targeted. Creating health meant providing not onlymedical health care, but health promotion programs and policies which would help people maintain healthy behaviours and lifestyles. While this individualistic healthy lifestyles approach to health worked for some (the wealthy members of society), people experiencing poverty, unemployment, underemployment or little control over the conditions of their daily lives benefited little from this approach. This was largely because both the healthy lifestyles approach and the medical approach to health largely ignored the social and environmental conditions affecting the health of people.

EDuring 1980s and 1990s there has been a growing swing away from seeing lifestyle risks as the root cause of poor health. While lifestyle factors still remain important, health is being viewed also in terms of the social, economic and environmental contexts in which people live. This broad approach to health is called the socio-ecological view of health. The broad socio-ecological view of health was endorsed at the first InternationalConferenceof Health Promotion held in 1986, Ottawa, Canada, where people from 38 countries agreed and declared that:The fundamental conditions and resources for health are peace, shelter, education, food, a viable income, a stable eco-system, sustainable resources, social justice and equity. Improvement in health requires a secure foundation in these basic requirements. (WHO, 1986).

It is clear from this statement that the creation of health is about much more than encouraging healthy individual behaviours and lifestyles and providing appropriate medical care. Therefore, the creation of health must include addressing issues such as poverty, pollution, urbanisation, natural resource depletion, social alienation and poor working conditions. The social, economic and environmental contexts which contribute to the creation of health do not operate separately or independently of each other. Rather, they are interacting and interdependent, and it is the complex interrelationships between them which determine the conditions that promote health. A broad socio-ecological view of health suggests that the promotion of health must include a strong social, economic and environmental focus.

FAt the Ottawa Conference in 1986, acharterwas developed which outlined new directions for health promotion based on the socio-ecological view of health. This charter, known as the Ottawa Charter for Health Promotion, remains as the backbone of health action today. In exploring the scope of health promotion it states that:Good health is a major resource for social, economic and personal development and an important dimension of quality of life. Political, economic, social, cultural, environmental, behavioural and biological factors can all favour health or be harmful to it. (WHO, 1986) .The Ottawa Charter brings practical meaning and action to this broad notion of health promotion. It presents fundamental strategies and approaches in achieving health for all. The overall philosophy of health promotion which guides these fundamental strategies and approaches is one of 'enabling people to increasecontrolover and to improve their health' (WHO, 1986).

NOT GIVENA.D.D. - Missing Out on LearningStudy requires a student's undivided attention. It is impossible to acquire a complex skill or absorb information about a subject in class unless one learns to concentrate without undue stress forlong periodsof time.StudentswithAttention Deficit Disorder(A.D.D.) are particularly deficient in this respect for reasons which are now known to be microbiological and not behavioral, as was once believed. Of course, being unable to concentrate, and incapable of pleasing the teacher and oneself in the process, quickly leads to despondence and low self-esteem. This will naturally induce behavioral problems. It is estimated that 3 - 5 % of all children suffer from Attention Deficit Disorder. There are three main types of Attention Deficit Disorder: A.D.D. without Hyperactivity, A.D.D. with Hyperactivity (A.D.H.D.), and Undifferentiated A.D.D.

The characteristics of a person with A.D.D. are as follows: has difficulty paying attention does not appear to listen is unable to carry out given instructions avoids or dislikes tasks which require sustained mental effort has difficulty with organization is easily distracted often loses things is forgetful indaily activitiesChildren with A.D.H.D. alsoexhibitexcessive and inappropriatephysical activity, such as constant fidgeting and running about the room. This boisterousness often interferes with theeducational developmentof others. Undifferentiated A.D.D. sufferers exhibit some, but not all, of the symptoms of each category.

It is important tobaseremedial action on an accurate diagnosis. Since A.D.D. is a physiologicaldisordercaused by some structural or chemically-based neurotransmitter problem in thenervous system, it responds especially well to certain psycho stimulant drugs, such as Ritalin. In use since 1953, the drug enhances the ability to structure and complete a thought without being overwhelmed by non-related and distracting thought processes.

Psycho stimulants are the most widely usedmedicationsfor persons with A.D.D. and A.D.H.D. Recent findings have validated the use of stimulant medications, which work in about 70 - 80% of A.H.D.D.children and adults(Wilens and Biederman, 1997). In fact, up to 90% of destructibility in A.D.D. sufferers can be removed by medication. The specific dose of medicine varies for each child, but such drugs are not without side effects, which include reduction in appetite,loss of weight, and problems with falling asleep.

Not all students who are inattentive in class have AttentionDeficit Disorder. Many are simply unwilling to commit themselves to the task at hand. Others might have aspecific learning disability(S.L.D.). However, those with A.D.D. have difficulty performing in school not usually because they have trouble learning 1 , but because of poor organization, inattention, compulsion and impulsiveness. This is brought about by an incompletely understood phenomenon, in which the individual is, perhaps, best described as 'tuning out' for short to long periods of time. The effect is analogous to the switching of channels on a television set. The difference is that an A.D.D. sufferer is not 'in charge of the remote control'. The child with A.D.D. is unavailable to learn - something else has involuntarily captured his or her whole attention.

It is commonly thought that A.D.D. only affects children, and that they grow out of the condition once they reach adolescence. It is now known that this is often not the case. Left undiagnosed or untreated, children with all forms of A.D.D. risk a lifetime of failure to relate effectively to others at home, school, college and at work. This brings significant emotional disturbances into play, and is very likely to negatively affect self-esteem. Fortunately, early identification of the problem, together with appropriate treatment, makes it possible for many victims to overcome the substantial obstacles that A.D.D. places in the way of successful learning.

BENEATH THE CANOPY

1.The world'stropical rainforestscomprise some 6% of the Earth's land area and contain more than half of all known life forms, or a conservative estimate of about 30 million species ofplants and animals. Some experts estimate there could be two or even three times as many species hidden within these complex and fast- disappearing ecosystems; scientists will probably never know for certain, so vast is the amount of study required.

2.Time is running out forbiological research.Commercial developmentis responsible for the loss of about 17 million hectares of virgin rainforest each year - a figure approximating 1% of what remains of the world's rainforests.

3.The current devastation of once impenetrable rainforest is of particular concern because, althoughnew treegrowth may in time repopulate felled areas, the biologically diverse storehouse offlora and faunais gone forever. Losing this bountiful inheritance, which took millions of years to reach its present highly evolved state,would be an unparalleled act of human stupidity.

4.Chemical compoundsthat might be extracted from yet-to-be-discovered species hidden beneath the tree canopy could assist in thetreatment of diseaseor help to control fertility. Conservationists point out that important medical discoveries have already been made from material found in tropical rainforests. The drug aspirin, now synthesised, was originally found in the bark of a rainforest tree. Two of the most potent anti- cancer drugs derive from the rosy periwinkle discovered in the 1950s in the tropical rainforests of Madagascar.

5.Therewardsof discovery are potentially enormous, yet the outlook is bleak. Timber-rich countriesmired in debt, view potential financial gain decades into the future as less attractive than short-term profit from logging. Cataloguing species and analysing newly-found substances takes time and money, both of which are in short supply.

6.The developed world takes every opportunity tolecturecountries which are the guardians of rainforest . Rich nations exhort them to preserve and care for what is left, ignoring the fact that their wealth was in large part due to theexploitationof their ownnatural world.

7.It is often forgotten that forests once covered most of Europe. Large tracts of forest were destroyed over the centuries for the same reason that the remainingrainforestsare now being felled - timber. As well as providing material for housing, it enabled wealthy nations to build large navies and shipping fleets with which to continue their plunder of the world's resources.

8.Besides, it is not clear thatdeveloping countrieswould necessarily benefit financially from extended bioprospecting of their rainforests. Pharmaceutical companies make huge profits from the sale of drugs with little return to the country in which an original discovery was made.

9.Also, cataloguing tropical biodiversity involves much more than a search for medically useful and therefore commercially viable drugs. Painstaking biological fieldwork helps to build immense databases of genetic, chemical and behavioural information that will be of benefit only to those countries developed enough to use them.

10.Reckless logging itself is not the only danger to rainforests. Fires lit to clear land for further logging and for housing and agricultural development played havoc in the late 1990s in the forests of Borneo. Massive clouds of smoke from burning forest fires swept across the southernmost countries of South-East Asia choking cities and reminding even the most resolute advocates of rainforest clearing of the swiftness of nature's retribution.

11.Nor are the dangers entirely to the rainforests themselves. Until very recently, so-called "lost" tribes - indigenous peoples who have had no contact with the outside world - still existed deep within certain rainforests. It is now unlikely that there are any more truly lost tribes. Contact with the modern world inevitably brings with it exploitation, loss of traditional culture, and, in an alarming number of instances, complete obliteration.

12.Forest-dwellers who have managed to live in harmony with their environment have much to teach us of lifebeneaththe treecanopy. If we do not listen, the impact will be on the entire human race. Loss of biodiversity, coupled with climate change and ecological destruction will have profound and lasting consequences.

The Danger of ECSTASY

Use of theillegal drugnamed Ecstasy (MDMA) has increased alarmingly in Britain over the last few years, and in 1992 theBritish Medical Journalclaimed that at least seven deaths and many s,evere adverse reactions have followed its use as a dance drug. 14 deaths have so far been attributed to the drug in Britain, although it is possible that other drugs contributed to some of those deaths. While it is true that all drugs by their very nature change the way in which the body reacts to its environment and are therefore potentially dangerous, it is still unclear whether casual use of Ecstasy is as dangerous as authorities believe. What is certain is that the drug causes distinct changes to the body which, unless understood, may lead to fatal complications in certain circumstances.

In almost all cases of MDMA-related deaths in Britain, overheating of the body and inadequate replacement of fluids have been noted as the primary causes of death. Yet in theUnited States, studies appear to implicate other causes since no deaths from overheating have yet been reported. It seems that normal healthy people are unlikely to die as a result of taking MDMA, but people with pre-existing conditions such as a weak heart or asthma may react in extreme ways and are well-advised not to take it.

Not all physical problems associated with the drug are immediate. Medium term andlong term effectshave been reported which are quite disturbing, yet not all are conclusively linked to the drug's use. Medium term effects include the possibility of contracting theliver disease hepatitis, or risking damage to the kidneys. However, animal studies show no such damage (although it is readily admitted by researchers that animal studies are far from conclusive since humans react in different ways than rats and monkeys to the drug), and cases of human liver or kidney damage have so far only been reported in Britain. Nonetheless, evidence to date suggests that alcohol and Ecstasy taken at the same time may result in lasting harm to bodily organs.

Evidence that MDMA causes long termcellulardamageto the brain has, until recently, been based on experiments with animals alone; the most common method of detection is to cut out a section of the brain, and measure the level of the chemical serotonin. This is performed weeks ormonths after use of a suspect drug. If theserotonin level, which is lowered as a result of the use of many drugs, fails to return to normal, then it is probable that the drug in question has caused damage to the cells of that part of the brain. Ecstasy has been implicated in causingbrain damagein this way, but in most cases the serotonin level returns to normal, albeit after a long time.

Early experiments with monkeys, in which they were found to havepermanentbrain damage as a result of being administered MDMA, were used to link brain damage in humans toEcstasyuse.These earlyconcernsled to the drug being classified as extremely dangerous, and although the results of the research were doubted by some and criticised as invalid, no attempt was made to change the classification. However, the latest available data regarding permanent brain damage in humans who have taken Ecstasy regularly over many years (as little as once a week for four years) seem to justify the cautious approach taken in the past. The psychological effects of taking Ecstasy are also a major cause for concern. It is clear that the mind is more readily damaged by the drug than is the body. It is not difficult to find occasional or regular users of the drug who will admit to suffering mental damage as a result. Paranoia, depression, loss of motivation and desire, bouts of mania - all are common, and not unusual side effects of the drug.

To be fair to those who claim that Ecstasy frees the personality by removing one's defenses against psychological attack, it is true that the drug can be liberating for some users. Unfortunately, the experience is likely to be short-lived, and there is always thedangeris that one's normal life might seem dull by comparison. .*

Perhaps the most damning evidence urging against the use of Ecstasy is that it is undoubtedly an addictive substance, but one that quickly loses its ability to transport the mind, while it increases its effect upon the body. Yet, unlike the classic addictive drugs, heroin, opium, morphine and so on, Ecstasy does not produce physical withdrawal symptoms. In fact, because one becomes quickly tolerant of its effect on the mind, it is necessary to forgo its use for a while in order to experience again its full effect. Any substance which produces such a strong effect on the user should be treated with appropriate respect and caution.

Creating Artificial ReefsIn thecoastal watersof the US, a nation's leftovers have been discarded. Derelict ships,concrete blocks, scrapped cars, army tanks, tyres filled with concrete and redundant planes litter the sea floor. However, this is notwaste disposal, but part of a coordinated, state-run programme. To recently arrived fish, plants and other sea organisms, theseartificial reefsare an ideal home, offering food and shelter.

Sea-dumping inciteswidespreadcondemnation. Little surprise when oceans are seen as 'convenient' dumping grounds for the rubbish we have created but would rather forget. However, scientific evidence suggests that if we dump the right things, sea life can actually be enhanced. And more recently, purpose-built structures of steel or concrete have beenemployed- some the size ofsmall apartmentblocks -principally to increase fish harvests.

Strong currents, for example, the choice of design and materials for an artificial reef depends on where it is going to be placed. In areas of a solid concrete structure will be more appropriate than ballasted tyres. It also depends on what species are to be attracted. It is pointless creating high-rise structures for fish that prefer flat or low-relief habitat. But the most important consideration is the purpose of the reef.

In the US, where there is a national reef plan usingcleanedup rigs and tanks, artificial reefs have mainly been used to attract fish forrecreational fishingor sport-diving. But there are many other ways in which they can be used to manage themarine habitat. For as well as protecting existing habitat, providing purpose-built accommodation for commercial species (such as lobsters and octupi) and acting as sea defences, they can be an effective way of improving fish harvests.

Japan, for example, has created vast areas of artificial habitat - rather than isolated reefs - to increase its fishstocks. In fact, the cultural and historical importance of seafood in Japan is reflected by the fact that it is aworld leaderin reef technology; what's more, those who construct and deploy reefs have sole rights to the harvest.

In Europe, artificial reefs have been mainly employed toprotect habitat. Particularly so in the Mediterranean where reefs have been sunk as physical obstacles to stop illegal trawling, which is destroyingsea grassbeds and the marine life that depends on them. If you want to protect areas of the seabed, you need something that will stop trawlers dead in their tracks,' says Dr Antony Jensen of the Southampton Oceanography Centre.

Italy boasts considerable artificial reef activity. It deployed its first scientifically planned reef using concrete cubes assembled in pyramid forms in 1974 to enhance fisheries and stop trawling. And Spain has built nearly 50 reefs in its waters, mainly to discourage trawling and enhance the productivity of fisheries. Meanwhile,Britainestablished its first quarried rock artificial reef in 1984 off the Scottish coast, to assess its potential for attractingcommercialspecies.

But while thescientific studyof these structures is a little over a quarter of a century old, artificial reefs made out of readily available materials such as bamboo and coconuts have been used by fishermen for centuries. And the benefits have been enormous. By placing reefs close to home, fishermen can save time and fuel. But unless they are carefully managed, these areas can become over- fished. In the Philippines, for example, where artificial reef programmes have been instigated in response to declining fish populations, catches are often allowed to exceed the maximum potential new production of the artificial reef because there is no proper management control.

There is no doubt that artificial reefs have lots to offer. And while purpose-built structures are effective, the real challenge now is to develop environmentally safe ways of using recycled waste to increase marine diversity. This will require more scientific research. For example, the leachates from one of the most commonly used reef materials, tyres, could potentially be harmful to the creatures and plants that they are supposed to attract. Yet few extensive studies have been undertaken into the long- term effects of disposing of tyres at sea. And at the moment, there is little consensus about what is environmentally acceptable to dump at sea, especially when it comes to oil and gas rigs. Clearly, the challenge is to develop environmentally acceptable ways of disposing of our rubbish while enhancing marine life too. What we must never be allowed to do is have an excuse for dumping anything we like at sea.
