经济学原理英文版Economics is the study of how individuals, businesses, and governments allocate resources to satisfy their wants and needs. It is a social science that seeks to understand the behavior of individuals and organizations in making choices about how to use scarce resources. The principles of economics are fundamental to understanding how the world works, and they can be applied to a wide range of real-world issues.One of the key principles of economics is the concept of scarcity. Scarcity refers to the limited nature of resources in the world. This means that there are not enough resources to produce everything that people want and need. As a result, individuals, businesses, and governments must make choices about how to allocate resources in the most efficient way.Another important principle of economics is the concept of opportunity cost. Opportunity cost refers to the value of the next best alternative that is given up when a choice is made. For example, if a student chooses to spend an hour studying for an exam rather than watching a movie, the opportunity cost of studying is the enjoyment that could have been gained from watching the movie. Understanding opportunity cost is crucial for making informed decisions about how to allocate resources.In addition to scarcity and opportunity cost, economics also examines how individuals and organizations make decisions at the margin. This means that they consider the additional benefits and costs of a decision, rather than just the total benefits and costs. For example, a business might consider whether it is worth it to produce one more unit of a product, taking into account the additional revenue and the additional costs of production.The study of economics also involves examining how markets work to allocate resources. Markets are systems that bring buyers and sellers together to exchange goods and services. The forces of supply and demand determine the prices of goods and services in a market, and these prices play a crucial role in allocating resources.Understanding how markets work is essential for understanding how the economy as a whole functions.Economics also explores the role of government in the economy. Governments play a key role in regulating markets, providing public goods and services, and redistributing income. The study of economics helps to understand the impact of government policies on the economy, and how these policies can be used to address issues such as inequality, unemployment, and inflation.In conclusion, the principles of economics are essential for understanding how individuals, businesses, and governments make decisions about how to allocate resources. By studying economics, we can gain insights into a wide range of real-world issues, and develop the analytical skills needed to make informed decisions in our personal and professional lives. Whether it is understanding the concept of scarcity, opportunity cost, or how markets work, the principles of economics provide a valuable framework for understanding the world around us.。

Digest Of The. Economist. 2006(6-7)欧阳光明（2021.03.07）Hard to digestA wealth of genetic information is to be found in the human gutBACTERIA, like people, can be divided into friend and foe. Inspired by evidence that the friendly sort may help with a range of ailments, many people consume bacteria in the form of yogurts and dietary supplements. Such a smattering of artificial additions, however, represents but a drop in the ocean. There are at least 800 types of bacteria living in the human gut. And research by Steven Gill of the Institute for Genomic Research in Rockville, Maryland, and his colleagues, published in this week's Science, suggests that the collective genome of these organisms is so large that it contains 100 times as many genes as the human genome itself.Dr Gill and his team were able to come to this conclusion by extracting bacterial DNA from the faeces of two volunteers. Because of the complexity of the samples, they were not able to reconstruct the entire genomes of each of the gut bacteria, just the individual genes. But that allowed them to make an estimate of numbers.What all these bacteria are doing is tricky to identify—the bacteria themselves are difficult to cultivate. So the researchers guessed at what they might be up to by comparing the genes they discovered withpublished databases of genes whose functions are already known.This comparison helped Dr Gill identify for the first time the probable enzymatic processes by which bacteria help humans to digest the complex carbohydrates in plants. The bacteria also contain a plentiful supply of genes involved in the synthesis of chemicals essential to human life—including two B vitamins and certain essential amino acids—although the team merely showed that these metabolic pathways exist rather than proving that they are used. Nevertheless, the pathways they found leave humans looking more like ruminants: animals such as goats and sheep that use bacteria to break down otherwise indigestible matter in the plants they eat.The broader conclusion Dr Gill draws is that people are superorganisms whose metabolism represents an amalgamation of human and microbial attributes. The notion of a superorganism has emerged before, as researchers in other fields have come to view humans as having a diverse internal ecosystem. This, suggest some, will be crucial to the success of personalised medicine, as different people will have different responses to drugs, depending on their microbial flora. Accordingly, the next step, says Dr Gill, is to see how microbial populations vary between people of different ages, backgrounds and diets.Another area of research is the process by which these helpful bacteria first colonise the digestive tract. Babies acquire their gut flora asthey pass down the birth canal and take a gene-filled gulp of their mother's vaginal and faecal flora. It might not be the most delicious of first meals, but it could well be an important one.Zapping the bluesThe rebirth of electric-shock treatmentELECTRICITY has long been used to treat medical disorders. As early as the second century AD, Galen, a Greek physician, recommended the use of electric eels for treating headaches and facial pain. In the 1930s Ugo Cerletti and Lucio Bini, two Italian psychiatrists, used electroconvulsive therapy to treat schizophrenia. These days, such rigorous techniques are practised less widely. But researchers are still investigating how a gentler electric therapy appears to treat depression.Vagus-nerve stimulation, to give it its proper name, was originally developed to treat severe epilepsy. It requires a pacemaker-like device to be implanted in a patient's chest and wires from it threaded up to the vagus nerve on the left side of his neck. In the normal course of events, this provides an electrical pulse to the vagus nerve for 30 seconds every five minutes.This treatment does not always work, but in some cases where it failed (the number of epileptic seizures experienced by a patient remaining the same), that patient nevertheless reported feeling much better after receiving the implant. This secondary effect led to trials for treating depression and, in 2005, America's Food and DrugAdministration approved the therapy for depression that fails to respond to all conventional treatments, including drugs and psychotherapy.Not only does the treatment work, but its effects appear to be long lasting. A study led by Charles Conway of Saint Louis University in Missouri, and presented to a recent meeting of the American Psychiatric Association, has found that 70% of patients who are better after one year stay better after two years as well.The technique builds on a procedure called deep-brain stimulation, in which electrodes are implanted deep into the white matter of patients' brains and used to “reboot” f aulty neural circuitry. Such an operation is a big undertaking, requiring a full day of surgery and carrying a risk of the patient suffering a stroke. Only a small number of people have been treated this way. In contrast, the device that stimulates the vagus nerve can be implanted in 45 minutes without a stay in hospital.The trouble is that vagus-nerve stimulation can take a long time to produce its full beneficial effect. According to Dr Conway, scans taken using a technique called positron-emission tomography show significant changes in brain activity starting three months after treatment begins. The changes are similar to the improvements seen in patients who undergo other forms of antidepression treatment. The brain continues to change over the following 21 months. Dr Conway says that patients should be told that the antidepressant effects could be slow in coming.However, Richard Selway of King's College Hospital, London,found that his patients' moods improved just weeks after the implant. Although brain scans are useful in determining the longevity of the treatment, Mr Selway notes that visible changes in the brain do not necessarily correlate perfectly with changes in mood.Nobody knows why stimulating the vagus nerve improves the mood of depressed patients, but Mr Selway has a theory. He believes that the electrical stimulation causes a region in the brain stem called the locus caeruleus (Latin, ironically, for “blue place”) to flood the brain with norepinephrine, a neurotransmitter implicated in alertness, concentration and motivation—that is, the mood states missing in depressed patients. Whatever the mechanism, for the depressed a therapy that is relatively safe and long lasting is rare cause for cheer.The shape of things to comeHow tomorrow's nuclear power stations will differ from today's THE agency in charge of promoting nuclear power in America describes a new generation of reactors that will be “highly economical” with “enhanced safety”, that “minimise wastes” and will prove “proliferation resistant”. No doubt they will bake a mean apple pie, too.Unfortunately, in the world of nuclear energy, fine words are not enough. America got away lightly with its nuclear accident. When the Three Mile Island plant in Pennsylvania overheated in 1979 very little radiation leaked, and there were no injuries. Europe was not so lucky. The accident at Chernobyl in Ukraine in 1986 killed dozens immediatelyand has affected (sometimes fatally) the health of tens of thousands at the least. Even discounting the association of nuclear power with nuclear weaponry, people have good reason to be suspicious of claims that reactors are safe.Yet political interest in nuclear power is reviving across the world, thanks in part to concerns about global warming and energy security. Already, some 441 commercial reactors operate in 31 countries and provide 17% of the planet's electricity, according to America's Department of Energy. Until recently, the talk was of how to retire these reactors gracefully. Now it is of how to extend their lives. In addition, another 32 reactors are being built, mostly in India, China and their neighbours. These new power stations belong to what has been called the third generation of reactors, designs that have been informed by experience and that are considered by their creators to be advanced. But will these new stations really be safer than their predecessors?Clearly, modern designs need to be less accident prone. The most important feature of a safe design is that it “fails safe”. For a re actor, this means that if its control systems stop working it shuts down automatically, safely dissipates the heat produced by the reactions in its core, and stops both the fuel and the radioactive waste produced by nuclear reactions from escaping by keeping them within some sort of containment vessel. Reactors that follow such rules are called “passive”. Most modern designs are passive to some extent and some newer onesare truly so. However, some of the genuinely passive reactors are also likely to be more expensive to run.Nuclear energy is produced by atomic fission. A large atom (usually uranium or plutonium) breaks into two smaller ones, releasing energy and neutrons. The neutrons then trigger further break-ups. And so on. If this “chain reaction” can be controlled, the energy released can be used to boil water, produce steam and drive a turbine that generates electricity. If it runs away, the result is a meltdown and an accident (or, in extreme circumstances, a nuclear explosion—though circumstances are never that extreme in a reactor because the fuel is less fissile than the material in a bomb). In many new designs the neutrons, and thus the chain reaction, are kept under control by passing them through water to slow them down. (Slow neutrons trigger more break ups than fast ones.) This water is exposed to a pressure of about 150 atmospheres—a pressure that means it remains liquid even at high temperatures. When nuclear reactions warm the water, its density drops, and the neutrons passing through it are no longer slowed enough to trigger further reactions. That negative feedback stabilises the reaction rate.Can business be cool?Why a growing number of firms are taking global warming seriously RUPERT MURDOCH is no green activist. But in Pebble Beach later this summer, the annual gathering of executivesof Mr Murdoch's News Corporation—which last year led to a dramatic shift in the mediaconglomerate's attitude tothe internet—will be addressed by several leading environmentalists, including a vice-president turned climatechangemovie star. Last month BSkyB, a British satellite-television company chaired by Mr Murdoch and run by hisson, James, declared itself “carbon-neutral”, having taken various steps to cut or offset its discharges of carboninto the atmosphere.The army of corporate greens is growing fast. Late last year HSBC became the first big bank to announce that itwas carbon-neutral, joining other financial institutions, including Swiss Re, a reinsurer, and Goldman Sachs, aninvestment bank, in waging war on climate-warming gases (of which carbon dioxide is the main culprit). Last yearGeneral Electric (GE), an industrial powerhouse, launched its “Ecomagination” strategy, aiming to cut its output ofgreenhouse gases and to invest heavily in clean (ie, carbon-free) technologies. In October Wal-Mart announced aseries of environmental schemes, including doubling the fuel-efficiency of its fleet of vehicles within a decade.Tesco and Sainsbury, two of Britain's biggest retailers, are competing fiercely to be the greenest. And on June 7thsome leading British bosses lobbied Tony Blair for a more ambitious policy on climate change, even if that involvesharsher regulation.The greening of business is by no means universal, however. Money from Exxon Mobil, Ford and General Motorshelped pay for television advertisements aired recently in America by the CompetitiveEnterprise Institute, with thedaft slogan “Carbon dioxide: they call it pollution; we call it life”. Besides, environmentalist critics say, some firmsare eng aged in superficial “greenwash” to boost the image of essentially climate-hurting businesses. Take BP, themost prominent corporate advocate of action on climate change, with its “Beyond Petroleum” ad campaign, highprofileinvestments in green energy, andev en a “carbon calculator” on its website that helps consumers measuretheir personal “carbon footprint”, or overall emissions of carbon. Yet, critics complain, BP's recent record profits arelargely thanks to sales of huge amounts of carbon-packed oil and gas.On the other hand, some free-market thinkers see the support of firms for regulation of carbon as the latestattempt at “regulatory capture”, by those who stand to profit from new rules. Max Schulz of the ManhattanInstitute, a conservative think tank, not es darkly that “Enron was into pushing the idea of climate change, becauseit was good for its business”.Others argue that climate change has no more place in corporate boardrooms than do discussions of other partisanpolitical issues, such as Darfur or gay marriage. That criticism, at least, is surely wrong. Most of the corporateconverts say they are acting not out of some vague sense of social responsibility, or even personal angst, butbecause climate change creates real business risks and opportunities—from regulatory compliance to insuringclients on flood plains. And although theseconcerns vary hugely from one company to the next, few firms can besure of remaining unaffected.Testing timesResearchers are working on ways to reduce the need for animal experiments, but new laws mayincrease the number of experiments neededIN AN ideal world, people would not perform experiments on animals. For the people, they are expensive. For theanimals, they are stressful and often painful.That ideal world, sadly, is still some way away. People need new drugs and vaccines. They want protection fromthe toxicity of chemicals. The search for basic scientific answers goes on. Indeed, the European Commission isforging ahead with proposals that will increase the number of animal experiments carried out in the EuropeanUnion, by requiring toxicity tests on every chemical approved for use within the union's borders in the past 25years.Already, the commission has identified 140,000 chemicals that have not yet been tested. It wants 30,000 of theseto be examined right away, and plans to spend between €4 billion-8 billion ($5 billion-10 billion) doing so. Thenumber of animals used for toxicity testing in Europe will thus, experts reckon, quintuple from just over 1m a yearto about 5m, unless they are saved by some dramatic advances in non-animal testing technology. At the moment,roughly 10% of European animal tests are forgeneral toxicity, 35% for basic research, 45% for drugs andvaccines, and the remaining 10% a variety of uses such as diagnosing diseases.Animal experimentation will therefore be around for some time yet. But the hunt for substitutes continues, and lastweekend the Middle European Society for Alternative Methods to Animal Testing met in Linz, Austria, to reviewprogress.A good place to start finding alternatives for toxicity tests is the liver—the organ responsible for breaking toxicchemicals down into safer molecules that can then be excreted. Two firms, one large and one small, told themeeting how they were using human liver cells removed incidentally during surgery to test various substances forlong-term toxic effects.PrimeCyte, the small firm, grows its cells in cultures over a few weeks and doses them regularly with the substanceunder investigation. The characteristics of the cells are carefully monitored, to look for changes in theirmicroanatomy.Pfizer, the big firm, also doses its cultures regularly, but rather than studying individual cells in detail, it counts cellnumbers. If the number of cells in a culture changes after a sample is added, that suggests the chemical inquestion is bad for the liver.In principle, these techniques could be applied to any chemical. In practice, drugs (and, in the case of PrimeCyte,food supplements) are top of the list. But that might change if the commission has its way: those 140,000screenings look like a lucrative market, although nobody knowswhether the new tests will be ready for use by2009, when the commission proposes that testing should start.Other tissues, too, can be tested independently of animals. Epithelix, a small firm in Geneva, has developed anartificial version of the liningof the lungs. According to Huang Song, one of Epithelix's researchers, the firm'scultured cells have similar microanatomy to those found in natural lung linings, and respond in the same way tovarious chemical messengers. Dr Huang says that they could be used in long-term toxicity tests of airbornechemicals and could also help identify treatments for lung diseases.The immune system can be mimicked and tested, too. ProBioGen, a company based in Berlin, is developing anartificial human lymph node which, it reckons, could have prevented the near-disastrous consequences of a drugtrial held in Britain three months ago, in which (despite the drug having passed animal tests) six men sufferedmultiple organ failure and nearly died. The drug the men were given made their immune systems hyperactive.Such a response would, the firm's scientists reckon, have been identified by their lymph node, which is made fromcells that provoke the immune system into a response. ProBioGen's lymph node could thus work better than animaltesting.Another way of cutting the number of animal experiments would be tochange the way that vaccines are tested, according to CoenraadHendriksen of the Netherlands Vaccine Institute. At themoment, allbatches of vaccine are subject to the same battery of tests. DrHendriksen argues that this is over-rigorous. When new vaccine culturesare made, belt-and-braces tests obviously need to be applied. But if abatch of vaccine is derived from an existing culture, he suggests that itneed be tested only to make sure it is identical to the batch from which itis derived. That would require fewer test animals.All this suggests that though there is still some way to go before drugs,vaccines and other substances can be tested routinely on cells ratherthan live animals, useful progress is being made. What is harder to see ishow the use of animals might be banished from fundamental research.Anger managementTo one emotion, men are more sensitive than womenMEN are notoriously insensitive to the emotional world around them. At least, that is the stereotype peddled by athousand women's magazines. And a study by two researchers at the University of Melbourne, in Australia,confirms that men are, indeed, less sensitive to emotion than women, with one important and suggestiveexception. Men are acutely sensitive to the anger of other men.Mark Williams and Jason Mattingley, whose study has just been published in Current Biology, looked at the way aperson's sex affects his or her response to emotionally charged facial expressions. People from all cultures agreeon what six basic expressions of emotion look like. Whether the face before you is expressing anger, disgust, fear,joy,sadness or surprise seems to be recognised universally—which suggests that the expressions involved areinnate, rather than learned.Dr Williams and Dr Mattingley showed the participants in their study photographs of these emotional expressions inmixed sets of either four or eight. They asked the participants to look for a particular sort of expression, andmeasured the amount of time it took them to find it. The researchers found, in agreement with previous studies,that both men and women identified angry expressions most quickly. But they also found that anger was morequickly identified on a male face than a female one.Moreover, most participants could find an angry face just as quickly when it was mixed in a group of eightphotographs as when it was part of a group of four. That was in stark contrast to the other five sorts of expression,which took more time to find when they had to be sorted from a larger group. This suggests that something in thebrain is attuned to picking out angry expressions, and that it is especially concerned about angry men. Also, thishighly tuned ability seems more important to males than females, since the two researchers found that men pickedout the angry expressions faster than women did, even though women were usually quicker than men to recognizeevery other sort of facial expression.Dr Williams and Dr Mattingley suspect the reason for this is that being able to spot an angry individual quickly hasa survival advantage—and, since anger is more likely to turn into lethal violence in men than inwomen, the abilityto spot angry males quickly is particularly valuable.As to why men are more sensitive to anger than women, it is presumably because they are far more likely to getkilled by it. Most murders involve men killing other men—even today the context of homicide is usually aspontaneous dispute over status or sex.The ability to spot quickly that an alpha male is in a foul mood would thus have great survival value. It would allowthe sharp-witted time to choose appeasement, defence or possibly even pre-emptive attack. And, if it is right, thisstudy also confirms a lesson learned by generations of bar-room tough guys and schoolyard bullies: if you wantattention, get angry.The shareholders' revoltA turning point in relations between company owners and bosses?SOMETHING strange has been happening this year at company annual meetings in America:shareholders have been voting decisively against the recommendations of managers. Until now, mostshareholders have, like so many sheep, routinely voted in accordance with the advice of the people theyemploy to run the company. This year managers have already been defeated at some 32 companies,including household names such as Boeing, ExxonMobil and General Motors.This shareholders' revolt has focused entirely on one issue: the method by which members of the boardof directors are elected. Shareholder resolutions on other subjects have mostly been defeated, asusual.The successful resolutions called for directors to be elected by majority voting, instead of by thetraditional method of “plurality”—which in practice meant that only votes cast in favour were counted,and that a single vote for a candidate would be enough to get him elected.Several companies, led by Pfizer, a drug giant, saw defeat looming and pre-emptively adopted a formalmajority-voting policy that was weaker than in the shareholder resolution. This required any director whofailed to secure a majority of votes to tender his resignation to the board, which would then be free todecide whether or not to accept it. Under the shareholder resolution, any candidate failing to secure amajority of the votes cast simply would not be elected. Intriguingly, the shareholder resolution wasdefeated at four-fifths of the firms that adopted a Pfizer-style majority voting rule, whereas it succeedednearly nine times out of ten at firms retaining the plurality rule.Unfortunately for shareholders, their victories may prove illusory, as the successful resolutions were all“precatory”—meaning that they merely advised management on the course of action preferred byshareholders, but did not force managers to do anything. Several resolutions that tried to imposemajority voting on firms by changing their bylaws failed this year.Even so, wise managers should voluntarily adopt majority voting, according to Wachtell, Lipton, Rosen &Katz, a Wall Street law firm that has generally helped managers resist increases in shareholder powerbutnow expects majority voting eventually to “become universal”. It advises that, at the very least,managers should adopt the Pfizer model, if only to avoid becoming the subject of even greater scrutinyfrom corporate-governance activists. Some firms might choose to go further, as Dell and Intel have donethis year, and adopt bylaws requiring majority voting.Shareholders may have been radicalised by the success last year of a lobbying effort by managersagainst a proposal from regulators to make it easier for shareholders to put up candidates in boardelections. It remains to be seen if they will be back for more in 2007. Certainly, some of the activistshareholders behind this year's resolutions have big plans. Where new voting rules are in place, they plancampaigns to vote out the chairman of the compensation committee at any firm that they think overpaysthe boss. If the 2006 annual meeting was unpleasant for managers, next year's could be far worse.Intangible opportunitiesCompanies are borrowing against their copyrights, trademarks and patentsNOT long ago, the value of companies resided mostly in things you could see and touch. Today it liesincreasingly in intangible assets such as the McDonald's name, the patent for Viagra and the rights toSpiderman. Baruch Lev, a finance professor at New York University's Stern School of Business, puts theimplied value of intangibles on Americancompanies' balance sheets at about $6 trillion, or two-thirds ofthe total. Much of this consists of intellectual property, the collective name for copyrights, trademarksand patents. Increasingly, companies and their clever bankers are using these assets to raise cash.The method of choice is securitisation, the issuing of bonds based on the various revenues thrown off byintellectual property. Late last month Dunkin' Brands, owner of Dunkin' Donuts, a snack-bar chain, raised$1.7 billion by selling bonds backed by, among other things, the royalties it will receive from itsfranchisees. The three private-equity firms that acquired Dunkin' Brands a few months ago have used thecash to repay the money they borrowed to buy the chain. This is the biggest intellectual-propertysecuritisation by far, says Jordan Yarett of Paul, Weiss, Rifkind, Wharton & Garrison, a law firm that hasworked on many such deals.Securitisations of intellectual property can be based on revenues from copyrights, trademarks (such aslogos) or patents. The best-known copyright deal was the issue in 1997 of $55m-worth of “Bowie Bonds”supported by the future sales of music by David Bowie, a British rock star. Bonds based on the films ofDreamWorks, Marvel comic books and the stories of John Steinbeck have also been sold. As well asDunkin' Brands, several restaurant chains and fashion firms have issued bonds backed by logos andbrands.Intellectual-property deals belong to a class known as operating-asset securitisations. These differ fromstandard securitisations of future revenues, such as bonds backed by the payments on a 30-yearmortgage or a car loan, in that the borrower has to make his asset work. If investors are to recoup theirmoney, the assets being securitised must be “actively exploited”, says Mr Yarett: DreamWorks mustcontinue to churn out box-office hits.The market for such securitisations is still small. Jay Eisbruck, of Moody's, a rating agency, reckons thataround $10 billion-worth of bonds are outs tanding. But there is “big potential,” he says, pointing out thatlicensing patented technology generates $100 billion a year and involves thousands of companies.Raising money this way can make sense not only for clever private-equity firms, but also for companieswith low (or no) credit ratings that cannot easily tap the capital markets or with few tangible assets ascollateral for bank loans. Some universities have joined in, too. Yale built a new medical complex withsome of the roughly $100m it raised securitising patent royalties from Zerit, an anti-HIV drug.It may be harder for investors to decide whether such deals are worth their while. They are, after all,highly complex and riskier than standard securitisations. The most obvious risk is that the investorscannot be sure that the assets will yield what borrowers promise: technology moves on, fashions changeand the demand for sugary snacks may collapse. Valuing intellectual property—an exercise based。

Suddenly it has arrived in many countries in Europe, triggering widespread alarm. The detection of the virus in wild birds across Europe is certainly a cause for concern, particularly to Europe's poultry farmers▲, wh o are rightfully worried that the presence of the virus in wild birds will increase the risk to their flocks. However, in the m_________②of a European debate about the benefits of vaccinating chickens and whether or not poultry should be brought indoors, there is a danger that far more significant events elsewhere will be ★overlooked[1].In particular, most attention should be f________③on the fact that bird flu is now widespread in the poultry flocks of two nations in Africa—Egypt and Nigeria—and in India. And on the fact that, in Nigeria, the disease is continuing to spread despite great efforts undertaken by the government. An outbreak in Afghanistan also appears to be inevitable.Arguably, these matter much more than the (also inevitable) arrival of the disease in Europe▲. Poor countries with large rural populations are in a far weaker position to handle, and ★stamp out[2], outbreaks of bird flu in poultry, through both ★culling[3] and the prevention of the movement of animals in the surrounding areas. In Africa and India, chickens and ducks are far more likely to be found ★roaming[4] in people's backyards, where they can mingle with humans, other d________④ animals and wildlife, thus spreading the disease. In Europe, by c_______⑤, most poultry are kept in regulated commercial farms.The opening up of a new African front for the bird-flu virus▲ is a problem because eradication there will be tremendously difficult. There is a high risk that the disease will spread to other countries on the continent and it could easily become endemic—as it has in Asia. This offers the virus huge new scope to mutate▲ and become a disease that can pass between humans. The virus is certainly mutating—genetic changes have already affected its biological behaviour, although apparently not yet its transmission between humans. Experts are unsure as to how much, and what kind, of genetic changes would be required for the virus to become a globalhealth threat. N_____⑥ do they know how long this process might take. But to ★dwell o n[5] the increased risk of a pandemic of influenza is to miss a serious point about the direct risks posed by the loss of a large numbers of chickens and ducks across Africa. For some time, the United Nations Food and Agriculture Organisation has been warning that if avian flu gets out of c_______⑦ in Africa, it will have a devastating impact on the livelihoods of millions of people. Poultry is a vital source of protein. For example, it provides almost 50% of the protein in the diet of Egyptians. The spread of a disease that is highly lethal to poultry, and requires culling, could have a ★dire[6] nutritional impact, there as elsewhere▲. Africa would also have to contend with huge economic losses. People who ★scratch out[7] a living in poor African nations simply cannot a_______⑧to lose their chickens. Most of the world's poor live in rural areas and depend on agriculture. In Africa, rather a lot of these poor people depend heavily on their poultry. It is easy to see why some believe that bird flu could turn out to be primarily a development—rather than just a health—issue for the whole African continent.No game of chickenWhat can be done? It is clear that the movement and trade of poultry is making a big contribution to the spread of the virus. That trade needs tighter regulation, as does the movement of live birds from countries with H5N1 infections. In such places trade should be suspended u_______⑨ flocks have been cleaned up.In addition, Nigeria and surrounding countries need seriouspublic-education campaigns about the danger of contact with dead birds. When outbreaks o______⑩, governments should immediately offer realistic compensation to farmers for birds lost to disease and culling▲. Without this, poor farmers will be tempted to hide bird-flu outbreaks and continue to sell poultry that should be culled. Farming practices that mix poultry species in farms or live animal markets are a danger too, and must be addressed—although that might take longer. The effort would be helped if those in the poultry industry and governments in poultry-exporting nations would stop simply pointing to the risks posed by wild birds and start paying more attention to the movement of animals, products and people from infected to un-infected regions and countries.Unusually for a complex probl em with international ★ramifications[8], money is available to make a serious attempt at tackling it▲—$1.9 billion was pledged by the world's wealthier nations last month in Beijing.

The fake fingernails on Ms Wu's right hand ★pluck[2] the strings, while her left hand fingers the ★frets[3]. （1）She produces an (B) (astonish) range of colours and moods from a 2,000-year-old instrument which produces a sound, observed a poet from the Tang dynasty, like “pearls falling into a jade plate”.Ms Wu is a ★virtuoso[4] interpreter of traditional music, creating (C) （haunt）exotic waves of sound with ★pi zzicatos and tremolos[5] (the plucking of one string with all five fingers consecutively).

She was the first to partner the pipa with an endongo (an eight-stringed Ugandan instrument), an Appalachian banjo and a string quartet6.

从太空采集太阳能Solar power from space,Beam it down 从太空采集太阳能,传送电力到地球吧Harvesting solar power in space, for use on Earth, comes a step closer to reality将太空收获的太阳电能在地球上利用，这种理想又向现实迈出了一大步。

THE idea of collecting solar energy in space and beaming it to Earth has been around for at least 70 years. In "Reason", a short story by Isaac Asimov that was published in 1941, a space station transmits energy collected from the sun to various planets using microwave beams.从太空中收集太阳能并将其传送到地球的想法已经存在了至少70年。

艾萨克·阿西莫夫(Isaac Asimov )在1941年出版的短篇小说Reason中曾设想利用微波束将空间站收集到的太阳能传送到各类行星上。

The advantage of intercepting sunlight in space, instead of letting it find its own way through the atmosphere, is that so much gets absorbed by the air. By converting it to the right frequency first (one of the so-called windows in the atmosphere, in which little energy is absorbed) a space-based collector could, enthusiasts claim, yield on average five times as much power as one located on the ground.从太空直接截获太阳光而不任由它们穿过大气层的优点是大部分光能量不会被大气吸收。

Digest Of The. Economist. 2006(8-9)The mismeasure of womanMen and women think differently. But not that differentlyIN THE 1970s there was a fad for giving dolls to baby boys and fire-engines to baby girls. The idea was that differences in behaviour between the sexes were solely the result of upbringing: culture turned women into ironers, knitters and chatterboxes, and men into hammerers, drillers and silent types. Switching toys would put an end to sexual sorting. Today, it is clear why it did not. When boys and girls are born, they are already different, and they favour different toys from the beginning.That boys and girls—and men and women—are programmed by evolution to behave differently from one another is now widely accepted. Surely, no one today would think of doing what John Money, of Johns Hopkins University, did in 1967: amputating the genitalia of a boy who had suffered a botched circumcision, and advising the parents to bring him up as a girl. The experiment didn't work, and the consequences were tragic. But which of the differences between the sexes are “biological”, in the sense that they have been honed by evolution, and which are “cultural” or “environmental” and might more easily be altered by changed circumstances, is still fiercely debated.The sensitivity of the question was shown last year by a furore at Harvard University. Larry Summers, then Harvard's president, caused a storm when he suggested that innate ability could be an important reason why there were so few women in the top positions in mathematics, engineering and the physical sciences.Even as a proposition for discussion, this is unacceptable to some. But biological explanations of human behaviour are making a comeback as the generation of academics that feared them as a covert way of justifying eugenics, or of thwarting Marxist utopianism, is retiring. The success of neo-Darwinism has provided an intellectual underpinning for discussion about why some differences between the sexes might be innate. And new scanning techniques have enabled researchers to examine the brain's interior while it is working, showing that male and female brains do, at one level, operate differently. The results, however, do not always support past clichés about what the differences in question actually are.Differences in behaviour between the sexes must, in some way, be reflections of systematic differences between the brains of males and females. Such differences certainly exist, but drawing inferences from them is not as easy as it may appear.For a start, men's brains are about 9% larger than those of women. That used to be cited as evidence of men's supposedly greater intelligence. Actually, the difference is largely (and probably completely) explained by the fact that men are bigger than women. In recent years, more detailed examination has refined the picture. Female brains have a higher percentage of grey matter (the manifestation, en bloc, of the central bodies of nerve cells), and thus a lower percentage of white matter (the manifestation of the long, thin filaments that connect nerve cells together), than male brains. That, plus the fact that in some regions of the female brain, nerve cells are packed more densely than in men, means that the number of nerve cells in male and female brains maybe similar.Oddly, though, the main connection between the two hemispheres of the brain, which is known as the corpus callosum and is made of white matter, is proportionately smaller in men than women. This may explain why men use only one side of the brain to process some problems for which women employ both sides.These differences in structure and wiring do not appear to have any influence on intelligence as measured by IQ tests. It does, however, seem that the sexes carry out these tests in different ways. In one example, where men and women perform equally well in a test that asks them to work out whether nonsense words rhyme, brain scanning shows that women use areas on both the right and the left sides of the brain to accomplish the task. Men, by contrast, use only areas on the left side. There is also a correlation between mathematical reasoning and temporal-lobe activity in men—but none in women. More generally, men seem to rely more on their grey matter for their IQ, whereas women rely more on their white matter.American exceptionalismThe world's biggest insurance market is too splinteredKANSAS CITY, Missouri, is known more for its historical role as a cattle town than as a financial hub. But it is to this midwestern city, America's 26th largest, that regulators and insurance executives from around the globe head when they want to make sense of the world's largest—and one of its weirdest—insurance markets.For it is in Kansas City that the National Association of Insurance Commissioners (NAIC) is housed. It oversees a market accounting for one-third of premiums written worldwide. Outside Kansas City, the market becomes a regulatory free-for-all. Each of America's 50 states, plus the District of Colombia, governs its insurance industry in its own way.In an increasingly global insurance market, America's state-based system is coming under strong pressure to reform. Insurance has changed dramatically since the NAIC was set up in 1871, with growing sophistication in underwriting and risk management. Premiums in America have ballooned to $1.1 trillion and market power is increasingly concentrated in the hands of big players (some of them foreign-owned) that are pushing for an overhaul of the state-based system. “It's an extremely expensive and Byzantine process,” says Bob Hartwig, an economist with the Insurance Information Institute, a research group.Though a fiercely political issue, congressional support for simplifying the system is gaining ground. Both houses of Congress are looking at proposals to change the state-based system. Big insurers favour a version that would implement an optional federal charter allowing them to bypass the state-bystate regulatory process if they choose. A similar system already exists for banks.Proponents of the changes see more efficiency, an ability to roll out products more quickly nationally and, ultimately, better offerings for consumers as a result. Yet some consumer groups favour state-based regulation. They believe it keeps premiums lower than they otherwise would be. Premiums as a percentage of gross output are lower in America than in several other countries.The political headwinds are strong: insurance commissioners are elected officials in some states (California, for instance) and appointed by the governor in others. The industry is also split: most of the country's 4,500 insurers are small, and many of them have close ties with state-based regulators, whose survival they support. But even these forces may eventually be overcome.Elsewhere in the industry in America, there are other calls for reform. In a backdoor form of protectionism, American reinsurance firms have long benefited from a regulation that requires foreign reinsurers writing cross-border business into America to post more collateral than they do. “If you operate outside the borders of the US, they don't trust you one inch,” laments Julian James, head of international business at Lloyd's of London, which writes 38% of its business in America.The collateral requirement was established because of worries about regulatory standards abroad, and the financial strength of global reinsurers. Today regulatory standards have been tightened in many foreign markets. A majority of America's reinsurance cover now comes from firms based abroad, including many that have set up offshore in Bermuda (for tax reasons) primarily to serve America.Too hot to handleDell's battery recall reveals the technology industry's vulnerabilitiesTHERE is the nail test, in which a team of engineers drives a large metal nail through a battery cell to see if it explodes. In another trial, laboratory technicians bake the batteries in an oven to simulate the effects of a digital device left in a closed car on a sweltering day—to check the reaction of the chemicals inside. On production runs, random batches of batteries are tested for temperature, efficiency, energy density and output.But the rigorous processes that go into making sophisticated, rechargeable batteries—the heart of billions of electronic gadgets around the world—were not enough. On August 14th Dell, a computer company, said it would replace 4.1m lithium-ion batteries made by Sony, a consumer-electronics firm, in laptop computers sold between 2004 and last month. A handful of customers had reported the batteries overheating, catching fire and even exploding—including one celebrated case at a conference this year in Japan, which was captured on film and passed around the internet. The cost to the two companies is expected to be between $200m and $400m.In some ways, Dell is a victim of its success. The company was a pioneer in turning the personal computer into a commodity, which meant squeezing suppliers to the last penny, using economies of scale by placing huge orders, and running efficient supply chains with little room for error. It all created a volatile environment in which mistakes can have grave effects.Since lithium-ion batteries were introduced in 1991, their capacity to overheat and burst into flame has been well known. Indeed, in 2004 America banned them as cargo on passenger planes, as a fire hazard. But the latest problems seem to have arisen because of the manufacturing process, which demands perfection. “If there is even a nano-sized particle of dust, a small metal shard or water condensation that gets into the battery cell, it can overheat and explode,” says Sara Bradford of Frost & Sullivan, a consultancy. As the energy needs of devices have grown rapidly, so have the demands on batteries.The computing industry's culture is also partly to blame. Firms have long tried to ship products as fast as they possibly can, and they may have set less store by quality. They used to mock the telecoms industry's ethos of “five-nines”—99.999% reliability—because it meant long product cycles. But now they are gradually accepting it as a benchmark. That is partly why Microsoft has taken so long to perfect its new operating system, Windows Vista.Compared with other product crises, from contaminated Coca-Cola in 1999 to Firestone's faulty tyres in 2000, Dell can be complimented for quickly taking charge of a hot situation. The firm says there were only six incidents of laptops overheating in America since December 2005—but the internet created a conflagration.Keeping the faithMixing religion and development raises soul-searching questionsWORLD Bank projects are usually free of words like “faith” and “soul.” Most of its missions speak the jargon of development: poverty reduction, aggregate growth and structural adjustments. But a small unit within the bank has been currying favour with religious groups, working to ease their suspicions and use their influence to further the bank's goals. In many developing countries, such groups have the best access to the people the bank is trying to help. The programme has existed for eight years, but this brainchild of the bank's previous president, James Wolfensohn, has spent the past year largely in limbo as his successor, Paul Wolfowitz, decides its future. Now, some religious leaders in the developing world are worried that the progress they have made with the bank may stall.That progress has not always been easy. The programme, named the Development Dialogue on Values and Ethics, faced controversy from the start. Just as religious groups have struggled to work with the bank, many people on the inside doubted if the bank should be delving into the divine. Critics argued that religion could be divisive and political. Some said religion clashes with the secular goals of modernisation.Although the bank does not lend directly to religious groups, it works with them to provide health, educational and other benefits, and receives direct input from those on the ground in poor countries. Katherine Marshall, director of the bank's faith unit, argues that such groups are in an ideal position to educate people, move resources and keep an eye on corruption. They are organised distribution systems in otherwise chaotic places. The programme has had success getting evangelical groups to fight malaria in Mozambique, improve microcredit and water distribution in India, and educate people about AIDS in Africa. “We started from very different viewpoints. The World Bank is looking at the survival of a country, we look at the survival of a patient,” says Leonardo Palombi, of the Community of Sant'Egidio, an Italian church group that works in Africa.Although the work continues, those involved in Mr Wolfensohn's former pet project now fret over its future. Some expect the faith unit to be transferred to an independent organisation also set up by Mr Wolfensohn, the World Faiths Development Dialogue, which will still maintain a link with the bank. Religious groups are hoping their voices will still be heard. “If we are going to make progress, faith institutions need to be involved. We believe religion has the ability to bring stability. It will be important for the bank to follow through,” says Agnes Abuom, of the World Council of Churches for Africa, based in Kenya.Like religious groups, large institutions such as the bank can resist change. Economists and development experts are sometimes slow to believe in new ideas. One positive by-product of the initiative is that religious groups once wary of the bank's intentions are less suspicious. Ultimately, as long as both economists and evangelists aim to help the poor attain a better life on earth, differences in opinion about the life hereafter do not matter much.Stand and deliverFor the first time since the epidemic began, money to fight AIDS is in plentiful supply. It isnow time to convert words into actionKEVIN DE COCK, the World Health Organisation's AIDS supremo, is not a man to mince his words. He reckons that he and his colleagues in the global AIDS establishment have between five and seven years to make a real dent in the problem. If they fail, the world's attention span will be exhausted, charitable donors and governments will turn to other matters and AIDS will be relegated in the public consciousness to being yet another intractable problem of the poor world about which little or nothing can be done.For now, though, the money is flowing. About $8.9 billion is expected to be available this year. And, regardless of Dr De Cock's long-term worries, that sum should rise over the next few years. Not surprisingly, a lot of people are eager to spend it.Many of those people—some 24,000 of them—have been meeting in Toronto at the 16th International AIDS Conference. An AIDS conference is unlike any other scientific meeting. In part, it is a jamboree in which people try to out-do each other in displays of cultural inclusiveness: the music of six continents resonates around the convention centre. In part, it is a lightning conductor that allows AIDS activists to make their discontent known to the world in a series of semi-official protests. It is also what other scientific meetings are, a forum for the presentation of papers with titles such as “Differing lymphocyte cytokine responses in HIV and Leishmania co-infection”. But mostly, it is a giant council of war. And at this one, the generals are trying to impose a complete change of military strategy.When AIDS was discovered, there was no treatment. Existing anti-viral drugs were tried but at best they delayed the inevitable, and at worst they failed completely. Prevention, then, was not merely better than cure, it was the only thing to talk about. Condoms were distributed. Posters were posted exhorting the advantages of safe sex. Television adverts were run that showed theconsequences of carelessness.Ten years ago, though, a new class of drugs known as protease inhibitors was developed. In combination with some of the older drugs, they produced what is now known as highly active anti-retroviral therapy or HAART. In most cases, HAART can prolong life indefinitely.That completely changed the picture. Once the AIDS activists had treated themselves, they began to lobby for the poor world to be treated, too. And, with much foot-dragging, that is now happening. About 1.6m people in low- and middle-income countries, 1m of them in sub-Saharan Africa, are now receiving anti-AIDS drugs routinely. The intention, announced at last year's G8 meeting in Scotland, is that the drugs should be available by 2010 to all who would benefit from them.However, those on drugs remain infected and require treatment indefinitely. To stop the epidemic requires a re-emphasis of prevention, and it is that which the organisers have been trying to do.Man, deconstructedThe DNA that may have driven the evolution of the human brainONE of the benefits of knowing the complete genetic sequences of humans and other animals is that it becomes possible to compare these blueprints. You can then work out what separates man from beast—genetically speaking, at least.The human brain sets man apart. About 2m years ago it began to grow in size, and today it is about three times larger than that of chimpanzees, man's closest relative. Human intelligence and behavioural complexity have far outstripped those of its simian cousins, so the human brain seems to have got more complex, as well as bigger. Yet no study has pinpointed the genetic changes that cause these differences between man and chimp.Now a group of scientists believe they have located some interesting stretches of DNA that may have been crucial in the evolution of the human brain. A team led by David Haussler of the Howard Hughes Medical Institute in California, compared the human genome with that of mammals including other primates. They reported the results in Nature.The researchers looked at the non-human genomes first, seeking regions that had not changed much throughout evolutionary history. Regions that are untouched by normal random changes typically are important ones, and thus are conserved by evolution. Next the researchers found the equivalent regions in the human genome to see if any were very different between humans and chimps. Such a sudden change is a hallmark of a functional evolutionary shift.They found 49 regions they dubbed “human accelerated regions” (HARs) that have shown a rapid, recent evolution. Most of these regions are not genes as commonly understood. This is because they code for something other than the proteins that are expressed in human cells and that regulate biological processes. A number of the HARs are portions of DNA that are responsible for turning genes on and off.Intriguingly, the most rapidly changing region was HAR1, which has accumulated 18 genetic changes when only one would be expected to occur by chance. It codes for a bit of RNA (a molecule that usually acts as a template for translating DNA into protein) that, it is speculated, has some direct function in neuronal development.HAR1 is expressed before birth in the developing neocortex—the outer layer of the brain that seems to be involved in higher functions such as language, conscious thought and sensory perception. HAR1 is expressed in cells that are thought to have a vital role in directing migrating nerve cells in the developing brain. This happens at seven to 19 weeks of gestation, a crucial time when many of the nerve cells are establishing their functions.Without more research, the function of HAR1 remains mere speculation. But an intriguing facet of this work is that, until now, most researchers had focused their hunt for differences on the protein-coding stretches of the genome. That such a discovery has been made in what was regarded as the less interesting parts of the human genome is a presage of where exciting genomic finds may lie in the future.Keeping it realHow to make digital photography more trustworthyPHOTOGRAPHY often blurs the distinction between art and reality. Modern technology has made that blurring easier. In the digital darkroom photographers can manipulate images and threaten the integrity of endeavours that rely on them. Several journalists have been fired for such activity in recent months, including one from Reuters for faking pictures in Lebanon. Earlier this year, the investigation into Hwang Woo-suk showed the South Korean scientist had changed images purporting to show cloning. In an effort to reel in photography, camera-makers are making it more obvious when images have been altered.One way of doing this is to use image-authentication systems to reveal if someone has tampered with a picture. These usecomputer programs to generate a code from the very data that comprise the image. As the picture is captured, the code is attached to it. When the image is viewed, software determines the code for the image and compares it with the attached code. If the image has been altered, the codes will not match, revealing the doctoring.Another way favoured by manufacturers is to take a piece of data from the image and assign it a secret code. Once the image file is transferred to a computer, it is given the same code, which will change if it is edited. The codes will match if the image is authentic but will be inconsistent if tampering occurred.The algorithm is the weapon of choice for Hany Farid, a computer scientist at Dartmouth College in New Hampshire. Digital images have natural statistical patterns in the intensity and texture of their pixels. These patterns change when the picture is manipulated. Dr Farid's algorithms detect these changes, and can tell if pixels have been duplicated or removed. They also try to detect if noise—the overexposed pixels within the image that create a grainy effect—was present at the time the photograph was taken or has been added later.However, forgers have become adept at printing and rescanning images, thus creating a new original. In such cases, analysing how three-dimensional elements interact is key. Long shadows at midday are a giveaway. Even the tiny reflections in the centre of a person's pupil tell you about the surrounding light source. So Dr Farid analyses shadows and lighting to see if subjects and surroundings are consistent.For its part, Adobe, the maker of Photoshop software, has improved its ability to record the changes made to an image by logging how and when each tool or filter was used. Photoshop was the program used by the journalist fired by Reuters; his handiwork left a pattern in the smoke he had added that was spotted by bloggers. Thus far the internet has proven an effective check on digital forgery. Although it allows potentially fake images to be disseminated widely, it also casts many more critical eyes upon them. Sometimes the best scrutiny is simply more people looking.Collateral damageWhy the war in Iraq is surprisingly bad news for America's defence firmsWHEN Boeing announced on August 18th that it planned to shut down production of the C-17, a huge military cargo plane, the news sent a shiver through the American defence industry. As it winds down its production line at Long Beach, California, over the next two years, Boeing will soon begin to notify suppliers that their services will no longer be needed. It had to call a halt, because orders from America's Defence Department had dried up and a trickle of export deals could not take their place. The company would not support the cost of running the production line for the C-17 (once one of its biggest-selling aircraft) on the off-chance that the Pentagon might change its mind and place further orders.The wider worry for the defence industry is that this could be the first of many big programmes to be shut down. A big part of the problem is that America is at war. The need to find an extra $100 billion a year to pay for operations in Iraq means there is pressure to make cuts in the defence budget, which has been provisionally set at $441 billion for the fiscal year beginning in October. American defence budgets involve a complicated dance starting with what the Pentagon wants, what the White House thinks it should get and, finally, what Congress allows it to get away with. Although the armed forces' extra spending on ammunition, fuel, provisions, medicines and accommodation in Iraq does not strictly come out of the same budget as new weapons, the heavy bill for fighting eventually leads to calls to save money on shiny new equipment.Earlier this month, for example, the Congressional Budget Office expressed “major concerns” about Future Combat Systems, a $165 billion project to upgrade all of the army's vehicles and communications networks. The scheme is the Pentagon's second-biggest development programme and is intended to give the soldiers on the ground access to real-time battlefield information from sources such as satellites and unmanned aircraft. But the programme was initially expected to cost about $82 billion, half the latest estimate, and critics are also worried about how well it will work and whether it will be delivered on time.Last week the army issued a glowing progress report on the project and insisted that Boeing and Science Applications International Corporation, the lead contractors, are on schedule. This was welcome news to defence contractors worried that the grandiose project might fall victim to pressure for budget cuts. Even so, the prospects for many other big weapons programmes are less rosy.The problem is not just the cost of the fighting in Iraq, but also its nature. The shift in the style of warfare, towards such “asymmetric” conflicts, means that there is now less demand for big-ticket weapons systems. Things were simpler in the cold war, when the Pentagon spent about $150 billion a year on new weapons. That fell to around $50 billion after the fall of the Berlin Wall. America's 15 main defence contractors reacted by consolidating into today's top five. When he became president, George Bush promised to increase defence spending, and he has done so: the procurement budget is back up to nearly $160 billion, despite thelack of a Soviet Union.As a result, the five main defence contractors—Lockheed Martin, Boeing, Northrop Grumman, General Dynamics and Raytheon—have had a wonderful five years. Since the terrorist attacks in September 2001, their sales have risen by around 10% a year. Last year their combined profits increased by 25% to almost $13 billion. Although most of the defence budget is spent on big weapons systems that are of little or no use in the fight against terrorists, the political climate after the attacks of September 11th 2001 made it impossible to oppose the administration's desire to increase defence spending. Besides, such spending means more jobs, often in areas where there is little other manufacturing.More media, less newsNewspapers are making progress with the internet, but most are still too timid, defensive orhigh-mindedTHE first thing to greet a visitor to the Oslo headquarters of Schibsted, a Norwegian newspaper firm, is its original, hand-operated printing press from 1856, now so clean and polished it looks more like a sculpture than a machine. Christian Schibsted, the firm's founder, bought it to print someone else's newspaper, but when the contract moved elsewhere he decided to start his own. Although Schibsted gives pride of place to its antique machinery, the company is in fact running away from its printed past as fast as it can. Having made a loss five years ago, Schibsted's activities on the internet contributed 35% of last year's operating profits.News of Schibsted's success online has spread far in the newspaper industry. Every year, says Sverre Munck, the executive vice-president of its international business, Schibsted has to turn away delegations of foreign newspaper bosses seeking to find out how the Norwegians have done it. “Otherwise we'd get several visits every month,” he says. The company has used its established newspaper brands to build websites that rank first and second in Scandinavia for visitors. It has also created new internet businesses such as Sesam, a search engine that competes with Google, and FINN.no, a portal for classified advertising. As a result, 2005 was the company's best ever for revenues and profits.Unfortunately for the newspaper industry, Schibsted is a rare exception. For most newspaper companies in the developed world, 2005 was miserable. They still earn almost all of their profits from print, which is in decline. As people look to the internet for news and young people turn away from papers, paid-for circulations are falling year after year. Papers are also losing their share of advertising spending. Classified advertising is quickly moving online. Jim Chisholm, of iMedia, a joint-venture consultancy with IFRA, a newspaper trade association, predicts that a quarter of print classified ads will be lost to digital media in the next ten years. Overall, says iMedia, newspapers claimed 36% of total global advertising in 1995 and 30% in 2005. It reckons they will lose another five percentage points by 2015.Even the most confident of newspaper bosses now agree that they will survive in the long term only if, like Schibsted, they can reinvent themselves on the internet and on other new-media platforms such as mobile phones and portable electronic devices. Most have been slow to grasp the changes affecting their industry—“remarkably, unaccountably complacent,” as Rupert Murdoch put it in a speech last year—but now they are making a big push to catch up. Internet advertising is growing rapidly for many and is beginning to offset some of the decline in print.Newspapers' complacency is perhaps not as remarkable as Mr Murdoch suggested. In many developed countries their owners have for decades enjoyed near monopolies, fat profit margins, and returns on capital above those of other industries. In the past, newspaper companies saw little need to experiment or to change and spent little or nothing on research and development.Changing connectionsFatherhood alters the structure of your brain—if you are a marmosetPARENTING has obvious effects on mothers, but fathers appear to be affected, too. A study published this week shows that fatherhood increases the nerve connections in the region of the brain that controls goal-driven behaviour—at least, it does in marmosets.Pregnancy and motherhood have long been known to bring about changes—many of them positive—to the female brain. Pregnant and nursing rats have a greater number of neural connections, particularly in the region of the brain that controls hormones and maternal behaviour. The brain changes coincide with improvements in spatial memory and speedier foraging skills, which might help a mother rat protect and feed her young.Just what effect parenting might have on the brains of fathers has remained an open question, however. Male rats sometimes eat their young rather than nurture them, which makes them a poor model for studying how fatherhood affects the brains of species that frown on infanticide. Marmoset fathers on the other hand are a model of paternal devotion. They carry their babies for more。

1.Whopper to go至尊汉堡，打包带走Will Burger King be gobbled up by private equity?汉堡王是否会被私人股本吞并？Sep 2nd 2010 | NEW YORKSHARES in Burger King (BK) soared on September 1st on reports that the fast-food company was talking to several private-equity firms interested in buying it. How much beef was behind these stories was unclear. But lately the company famous for the slogan “Have It Your Way” has certainly not been having it its own way. There may be arguments about whether BK or McDonald’s serves the best fries, but there is no doubt which is more popular with stockmarket investors: the maker of the Big Mac has supersized its lead in the past two years.有报道披露，快餐企业汉堡王（BK）正在与数个有收购意向的私人股本接洽，9月1日，汉堡王的股值随之飙升。

这些报道究竟有多少真材实料不得而知。

汉堡王的著名口号是“我选我味”，但如今显然它身不由己，心中五味杂陈。

汉堡王和麦当劳哪家薯条最好吃，食客们一直争论不休，但股票投资人更喜欢哪家股票，却一目了然：过去两年里，巨无霸麦当劳一直在扩大自己的优势。

人声是最佳乐器大问题系列：爱德华·卡尔认为最好的乐器是我们大家都拥有的……From INTELLIGENT LIFE magazine, May/June 2012最好的乐器我们人人都有，时时携带，那就是人声。

几年之前，在爱尔兰临大西洋的当风海岸上，有几位老农拜访了我家的小屋。

那晚家里有茶有酒，火炉里还有干草在燃烧。

待到深夜屋外又黑又冷之时，一个老农突然开始唱歌。

寂静之中只有他的声音在空气中回荡，高亢且刺耳，悲伤地吟咏着班纳海滩的民谣。

在那样的时刻，歌声变成了我们生命的配乐。

所有一切都始于我们最早听到的音乐——母亲的声音。

在世界各地，每周六在体育场的看台上，每周日在教堂的长椅中，人们合声高唱。

正是人们张嘴歌唱赋予生日、婚礼和葬礼庄重的典礼感。

一旦音乐中混有声音，不管你所喜欢的是卡拉斯还是阿黛尔，抑或是皇后乐队，乐器都变成了陪衬。

声音如同指纹一般在音乐上加入了个性化的标记，且能够带出无尽的变化。

借用口语中的爆破音和摩擦音，人声赋予音乐一层感觉、一种情绪或是一个故事，这个故事可能涉及到一位负心人，也可能讲述着为爱尔兰复活节起义运送枪弹却最终无缘抵达班纳海滩的船只。

几乎所有形式的音乐都带有人声的痕迹。

当你倾听肖邦委婉的序曲时，你所听到的是模仿人声的钢琴。

当你倾听弦乐四重奏时，你所听到的是女高音、女低音、男高音和男低音的合唱。

我的小提琴老师克莱伦斯·梅亚斯克福想要让我理解如何为一首旋律分节时，他并不会用他那架精美的17世纪马吉尼来做示范，相反他会用自己平淡无奇的20世纪声音演唱示范。

歌唱对我们有很大的益处。

集中精神用力歌唱可以赋予头脑和身体活力。

唱歌过程中的呼吸吐气清通我们的气管，可以预防咳嗽和感冒。

大声高歌也可以发泄心中的不平。

为什么不试试这是否有效呢？如果你没有足够的信心加入本地合唱团，那你至少可以在家里无人的情况下，把自己安全地关在浴室里淋个浴，同时张开嘴，深吸一口气，释放一下你自己的灌耳魔音。

Digest Of The. Economist. 2006(2-3)Moving marketsShifts in trading patterns are making technology ever more importantAN INVESTOR presses a button, sending 1,000 small “buy” orders to a stock exchange. The exchange's computer system instantly kicks in, but a split second later, 99% of the orders are cancelled. Having found the best price, the investor makes his trade discreetly, leaving no visible trace on the market—all in less time than it takes to blink. His stealth strategy remains intact.Events like this happen many times a day, as floods of orders from active hedge funds and “algorithmic” traders—who use automated programs to buy and sell—rush through the information-technology systems of the world's exchanges. The average transaction size on leading stock exchanges has fallen from about 2,000 shares in the mid-1990s to fewer than 400 today, although total trading volume has soared. But exchanges' systems have to cope with more than just a growing onslaught of “buy” and “sell” messages. Customers want to trade in more complicated ways, combining different types of assets on different exchanges at once. Then, as always, there is regulation. All this is pushing technology further to the fore.Recent embarrassments at the Tokyo Stock Exchange have illustrated what can happen when systems fail to keep up with the times. In just the past few months, the importance of technology has been plain in mergers (those of the New York Stock Exchange and Archipelago, and NASDAQ and INET); collaborations (the decision by the New York Board of Trade to use the Chicago Board of Trade's trading platform); and the creation of off-exchange trading networks (including one unveiled recently by Citigroup).Technology is hardly a new element in financial markets: the advent of electronic trading in the 1980s (first in Europe, later in America) helped to globalise financial markets and drove up trading volumes. But having slowed after the dotcom bubble it is now demanding ever more of exchanges' and intermediaries' attention. Investors can now deal more easily with exchanges or each other, bypassing traditional routes. As customers' demands and bargaining power have increased, so the exchanges have had to ramp up their own systems. “Technology created the monster that has to be ad dressed by more technology,” says Leslie Sutphen of Calyon Financial, a big futures broker.Aite Group, a research firm, reckons that in America alone the securities and investment industry spent $26.4 billion last year on IT (see chart), and may spend $30 billion in 2008. Sell-side firms spend most: J.P. Morgan Chase and Morgan Stanley each splashed out more than $2 billion in 2004, while asset-management firms such as State Street Global Advisors, Barclays Global Investors and Fidelity Investments spent between $250m and $350m apiece. With brokerage fees for trades whittled down, many have concluded that better technology is one way to cut trading costs and keep customers.Testing all enginesGlobal growth is looking less lopsided than for many yearsLARR Y SUMMERS, a Treasury secretary under Bill Clinton, once said that “the world economy is flying on one engine” to describe its excessive reliance on American demand. Now growth seems to be becoming more even at last: Europe and Japan are revving up, as are most emerging economies. As a result, if (or when) the American engine stalls, the global aeroplane will not necessarily crash.For the time being, America's monetary policymakers think that their economy is still running pretty well. This week, as Alan Greenspan handed over the chairmanship of the Federal Reserve to Ben Bernanke, the Fed marked the end of Mr Greenspan's18-year reign by raising interest rates for the 14th consecutive meeting, to 4.5%. The central bankers also gave Mr Bernanke more flexibi lity by softening their policy statement: they said that further tightening “may be needed”rather than “is likely to be needed”, as before.Most analysts expect the Fed to raise rates once or twice more, although the economy slowed sharply in late 2005. Real GDP growth fell to an annual rate of only 1.1% in the fourth quarter, the lowest for three years. Economists were quick to ascribe this disappointing number to special factors, such as Hurricane Katrina and a steep fall in car sales—the consequence of generous incentives that had encouraged buyers to bring purchases forward to the third quarter. The consensus has it that growth will bounce back to an annual rate of over 4% in the first quarter and stay strong thereafter.This sounds too optimistic. A rebound is indeed likely in this quarter, but the rest of the year could prove disappointing, as a weakening housing market starts to weigh on consumer spending. In December sales of existing homes fell markedly and the stock of unsold homes surged. Economists at Goldman Sachs calculate that, after adjusting for seasonal patterns, the median home price has fallen by almost 4% since October. Experience from Britain and Australia shows that even a soft landing for house prices can cause an acute slowdown in consumer spending.American consumers have been the main engine not just of their own economy but of the whole world's. If that engine fails, will the global economy nose-dive? A few years ago, the answer would probably have been yes. But the global economy may now be less vulnerable. At the World Economic Forum in Davos last week, Jim O'Neill, the chief economist at Goldman Sachs, argued convincingly that a slowdown in America need not lead to a significant global loss of power.Start with Japan, where industrial output jumped by an annual rate of 11% in the fourth quarter. Goldman Sachs has raised its GDP growth forecast for that quarter (the official number is due on February 17th) to an annualized 4.2%. That would pushyear-on-year growth to 3.9%, well ahead of America's 3.1%. The bank predicts average GDP growth in Japan this year of 2.7%. It thinks strong demand within Asia will partly offset an American slowdown.Japan's labour market is also strengthening. In December the ratio of vacancies to job applicants rose to its highest since 1992 (see chart 1). It is easier to find a job now than at any time since the bubble burst in the early 1990s. Stronger hiring by firms is also pushing up wages after years of decline. Workers are enjoying the biggest rise in bonuses for over a d ecade.Pass the parcelOnline shoppers give parcels firms a new lease of lifeTHINGS must be going well in the parcels business. At $2.5m for a 30-second TV commercial during last weekend's Super Bowl, an ad from FedEx was the one many Americans found the most entertaining. It showed a caveman trying to use a pterodactyl for an express delivery, only to watch it be gobbled up on take-off by a tyrannosaur. What did the world do before FedEx, the ad inquired? It might have asked what on earth FedEx did before the arrival of online retailers, which would themselves be sunk without today's fast and efficient delivery firms.Consumers and companies continue to flock in droves to the internet to buy and sell things. FedEx reported its busiest period ever last December, when it handled almost 9m packages in a single day. Online retailers also set new records in America. Excluding travel, some $82 billion was spent last year buying things over the internet, 24% more than in 2004, according to comScore Networks, which tracks consumer behaviour. Online sales of clothing, computer software, toys, and home and garden products were all up by more than 30%. And most of this stuff was either posted or delivered by parcel companies.The boom is global, especially now that more companies are outsourcing production. It is becoming increasingly common for products to be delivered direct from factory to consumer. In one evening just before Christmas, a record 225,000 international express packages were handled by UPS at a giant new air-cargo hub, opened by the American logistics firm at Cologne airport in Germany. “The internet has had a profound effect on our business,” says David Abney, UPS's international president. UPS now handles more than 14m packages worldwide every day.It is striking that postal firms—once seen as obsolete because of the emergence of the internet—are now finding salvation from it. People are paying more bills online and sending more e-mails instead of letters, but most post offices are making up for that thanks to e-commerce. After four years of profits, the United States Postal Service has cleared its $11 billion of debt.Firms such as Amazon and eBay have even helped make Britain's Royal Mail profitable. It needs to be: on January 1st, the Royal Mail lost its 350-year-old monopoly on carrying letters. It will face growing competition from rivals, such as Germany's Deutsche Post, which has expanded vigorously after partial privatisation and now owns DHL, another big international delivery company.Both post offices and express-delivery firms have developed a range of services to help ecommerce and eBay's traders—who listed a colossal 1.9 billion items for sale last year. Among the most popular services are tracking numbers, which allow people to follow the progress of their deliveries on the internet.A question of standardsMore suggestions of bad behaviour by tobacco companies. MaybeANOTHER round has just been fought in the battle between tobacco companies and those who regard them as spawn of the devil. In a paper just published in the Lancet, with the provocative title “Secret science: tobacco industry research on smoking behaviour and cigarette toxicity”, David Hammond, of Waterloo University in Canada and Neil Collishaw and Cynthia Callard, two members of Physicians for a Smoke-Free Canada, a lobby group, criticise the behaviour of British American Tobacco (BAT). They say the firm considered manipulating some of its products in order to make them low-tar in the eyes of officialdom while they actually delivered high tar and nicotine levels to smokers.It was and is no secret, as BAT points out, that people smoke low-tar cigarettes differently from high-tar ones. The reason is that they want a decent dose of the nicotine which tobacco smoke contains. They therefore pull a larger volume of air through the cigarette when they draw on a low-tar rather than a high-tar variety. The extra volume makes up for the lower concentration of the drug.But a burning cigarette is a complex thing, and that extra volume has some unexpected consequences. In particular, a bigger draw is generally a faster draw. That pulls a higher proportion of the air inhaled through the burning tobacco, rather than through the paper sides of the cigarette. This, in turn, means more smoke per unit volume, and thus more tar and nicotine. The nature of the nicotine may change, too, with more of it being in a form that is easy for the body to absorb.According to Dr Hammond and his colleagues, a series of studies conducted by BAT's researchers between 1972 and 1994 quantified much of this. The standardised way of analysing cigarette smoke, as laid down by the International Organisation for Standardisation (ISO), which regulates everything from computer code to greenhouse gases, uses a machine to make 35-millilitre puffs, drawn for two seconds once a minute. The firm's researchers, by contrast, found that real smokers draw 50-70ml per puff, and do so twice a minute. Dr Hammonds's conclusion is drawn from the huge body of documents disgorged by the tobacco industry as part of various legal settlements that have taken place in the past few years, mainly as a result of disputes with the authorities in the United States.Dr Hammond suggests, however, the firm went beyond merely investigating how people smoked. A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design.A research report from 1979 puts it thus: “There are three major design featur es which can be used either individually or in combination to manipulate delivery levels; filtration, paper permeability, and filter-tip ventilation.” A conference paper from 1983 says, “The challenge would be to reduce the mainstream nicotine determined by standard smoking-machine measurement while increasing the amount that would actually be absorbed by the smoker”. Another conference paper, from 1984, says: “We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...It should also be capable of delivering up to 100% more than its machine delivery.”Thanks to the banksCollege students learn more about market ratesA GOOD education may be priceless, but in America it is far from cheap—and it is not getting any cheaper. On February 1st Congress narrowly passed the Deficit Reduction Act, which aims to slim America's bulging budget deficit by, among other things, lopping $12.7 billion off the federal student-loan programme. Interest rates on student loans will rise while subsidies fall.Family incomes, grant aid and federal loans have all failed to keep pace with the growth in the cost of tuition. “The funding gap between what students can afford and what higher education costs has got wider and wider,” says Claire Mezzanotte of Fitch, a ratings agency. Lenders are rushing to bridge the gap with “private” student loans—loans that are free of government subsidies and guarantees.Virtually non-existent ten years ago, private student loans in the 2004-05 school year amounted to $13.8 billion—a compound annual growth rate of almost 30%—and they are expected to double in the next three years. According to the College Board, an association of schools and colleges, private student loans now make up nearly 22% of the volume of federal student loans, up from a mere 5% in 1994-95.The growth shows little sign of slowing. Education costs continue to climb while pressure on Congress to pare down the budget deficit means federal aid will, at best, stay at current levels. Meanwhile, the number of students attending colleges and tradeschools is expected to soar as the children of post-war baby-boomers continue matriculating.Private student loans are popular with lenders because they are profitable. Lenders charge market rates for the loans (the rates on federal student loans are capped) before adding up-front fees, which can themselves be around 6-7% of the loan. Sallie Mae, a student-loan company and by far the biggest dispenser of private student loans, disclosed in its most recent report that the average spread on its private student lending was 4.75%, more than three times the 1.31% it made on its federally backed loans.All of this is good news when lenders are hungry for new areas of growth in the face of a cooling mortgage market. Private student loans, says Matthew Snowling of Friedman, Billings, Ramsey, an investment bank, are probably “the fastest-growing segment of consumer finance—and by far the most profitable one—at a time when finding asset growth is challenging.” Last December J.P. Morgan, which already had a sizeable education-finance unit, snapped up Collegiate Funding Services, a Virginia-based provider of federal and private student loans. Companies from Bank of America to GMAC, the financing arm of General Motors, have jumped in. Other consumer-finance companies, such as Capital One, are whispered to be eyeing the market.In the beginning...How life on Earth got going is still mysterious, but not for want of ideasNEVER make forecasts, especially about the future. Samuel Goldwyn's wise advice is well illustrated by a pair of scientific papers published in 1953. Both were thought by their authors to be milestones on the path to the secret of life, but only one has so far amounted to much, and it was not the one that caught the public imagination at the time.James Watson and Francis Crick, who wrote “A structure for deoxyribose nucleic acid”, have become as famous as rock stars for asking how life works and thereby starting a line of inquiry that led to the Human Genome Project. Stanley Miller, by contrast, though lauded by his peers, languishes in obscurity as far as the wider world is concerned. Yet when it appeared, “Production of amino acids under possible primitive Earth conditions” was expected to begin a scientific process that would solve a problem in some ways more profound than how life works at the moment—namely how it got going in the first place on the surface of a sterile rock 150m km from a small, unregarded yellow star.Dr Miller was the first to address this question experimentally. Inspired by one of Charles Darwin's ideas, that the ingredients of life might have formed by chemical reactions in a “warm, little pond”, he mixed the gases then thought to have formed the atmosphere of the primitive Earth— methane, ammonia and hydrogen—in a flask half-full of boiling water, and passed electric sparks, mimicking lightning, through them for several days to see what would happen. What happened, as the name of the paper suggests, was amino acids, the building blocks of proteins. The origin of life then seemed within grasp. But it has eluded researchers ever since. They are still looking, though, and this week several of them met at the Royal Society, in London, to review progress.The origin question is really three sub-questions. One is, where did the raw materials for life come from? That is what Dr Miller was asking. The second is, how did those raw materials spontaneously assemble themselves into the first object to which the term “alive” might reasonably be applied? The third is, how, having once come into existence, did it survive conditions in the early solar system?The first question was addressed by Patrick Thaddeus, of the Harvard-Smithsonian Centre for Astrophysics, and Max Bernstein, who works at the Ames laboratory, in California, part of America's space agency, NASA. As Dr Bernstein succinctly put it, the chemical raw materials for life, in the form of simple compounds that could then be assembled into more complex biomolecules, could come from above, below or beyond.Full to burstingRising levels of carbon dioxide will dump even more water into the oceansTHE lungs of the planet, namely green-leafed plants that breathe in carbon dioxide and breathe out oxygen, also put water vapour into the atmosphere. Just as people lose water through breathing (think of the misted mirror used to check for vital signs), so, too, do plants. The question is, what effect will rising concentrations of carbon dioxide have on this? The answer, published in this week's Nature by Nicola Gedney of Britain's Meteorological Office and her colleagues, would appear to be, less water in the atmosphere and more in the oceans.Measurements of the volume of water that rivers return to the oceans show that, around the world, rivers have become fuller over the past century. In theory, there are many reasons why this could be so, but some have already been discounted. Research has established, for example, that it is not, overall, raining—or snowing, hailing or sleeting—any more than it used to. But there are other possibilities. One concerns changes in land use, such as deforestation and urbanisation. The soil in rural areas soaks up the rain and trees breathe it back into the atmosphere, whereas the concrete in urban areas transfers rainwater into drains and hence into rivers. Another possibility is “solar dimming”, in which aerosol particles create a hazy atmosphere that holds less water. And then there is the direct effect of carbon dioxide on plant transpiration.Dr Gedney used a statistical technique called “optimal fingerprinting” or “detection and attribution” to identify which of these four factors matter. Her team carried out five simulations of river flow in the 20th century. In the first of these they allowed all four explanations to vary: rainfall, haze, atmospheric carbon dioxide and land use. They then held one of them constant in each of the next four simulations. By comparing the outcome of each of these with the first simulation, the team gained a sense of its part in the overall picture. So, for example, they inferred the role of land use by deducting the simulation in which it was fixed from the simulation in which it varied.As with any statistical analysis, the results are only as good as the model, the experimental design and the data. Dr Gedney and her colleagues acknowledge that their model does not fully take into account the use of water to irrigate crops—particularly important in Asia and Europe—nor the question of urban growth. They argue, however, that these aspects, taken together, would remove water from rivers, which makes their conclusion all the more striking. And it is this: fuller rivers cannot be explained by more rainfall or haze or changes in land use, but they can be explained by higher concentrations of atmospheric carbon dioxide.The mechanism is straightforward. A plant breathes through small holes, called stomata, found in its leaves. Plants take in carbon dioxide, and when the atmosphere is relatively rich in this gas, less effort is needed. The stomata stay closed for longer, and less water is lost to the atmosphere. This means that the plant doesn't need to draw as much moisture from the soil. The unused water flows into rivers.The great tech buy-out boomWill the enthusiasm of private-equity firms for investing in technology and telecoms end in tears, again?PRIME COMPUTERS, Rhythm NetConnections and XO Communications—all names to drain the blood from the face of a private-equity investor. Or so it was until recently, when investing in technology and telecoms suddenly became all the rage for private-equity companies. These investment firms—labelled “locusts” by unfriendly Europeans—generally make their money by buying big controlling stakes in companies, improving their efficiency, and then selling them on.In the late 1980s, Prime Computers became private equity's first great “tech wreck”, humiliating investors who thought they understood the technology business and could nurture the firm back to health away from the shorttermist pressures of the public stockmarket. After Prime failed, private-equity firms spent the best part of a decade focusing solely on the old economy. Only in the late 1990s, when the new economy was all the rage, did they pluck up the courage to return to tech and telecoms—a decision some of the grandest names in the industry were soon to regret. Hicks, Muse, Furst and Tate (Rhythm NetConnections) and Forstmann Little (XO) have both been shadows of their old selves since losing fortunes on telecoms.Now, investing in technology and telecoms is once again one of the hottest areas in the super-heated privateequity market. The multi-billion-dollar question is: will this round of investment end any less horribly than the previous two?Last month TDC, a Danish phone company, was finally acquired after a bid of $15.3 billion by a consortium including European giants Permira Advisors and Apax Partners, and American veterans Kohlberg Kravis Roberts (KKR), Blackstone Group and Providence Equity Partners. In the past five years, there has been private-equity involvement in about 40% of telecoms deals in Europe.On the other side of the Atlantic, the action has focused mainly on technology, rather than telecoms. Last summer, a consortium including Silver Lake Partners and KKR completed the biggest private-equity tech deal to date, buying SunGard Data Systems, a financial-technology firm, for $11.3 billion. Since then the deals have continued to flow. The $1.2 billion acquisition of Serena Software by Silver Lake is due to be completed by the end of March. Blackstone and others are said to be circling two IT outsourcing firms—Computer Sciences and ACS.There are reasons to hope that this time will be different. In telecoms, for instance, private-equity firms are mostly trying to buy established firms—often former national monopolists—that, while they might be threatened by internet telephony, have strong cash flow, physical assets and plenty of scope to improve the quality of management. These are the sorts of characteristicsprivate-equity investors thrive on. By contrast, the disastrous investments in the late 1990s were in new telecoms firms that were building their operations.In technology, private-equity interest has grown as the industry has matured, and cash-flow and profitability have become more predictable. Until recently, it has been the norm for tech firms to plough back all their profit and cashflow into investing in the business. They have carried no debt and paid no dividends. Now private-equity firms see the opportunity to pursue their classic strategy of buying firms by borrowing against cashflow, and then returning money to shareholders. Glenn Hutchins of Silver Lake thinks the tech sector is now in a similar condition to the old economy in America in the early 1980s, which is when private equity first started to have an impact, by restructuring and consolidating many industries.How to live for everThe latest from the wacky world of anti-senescence therapyDEATH is a fact of life—at least it has been so far. Humans grow old. From early adulthood, performance starts to wane. Muscles become progressively weaker, cognition fails. But the point at which age turns to ill health and, ultimately, death is shifting—that is, people are remaining healthier for longer. And that raises the question of how death might be postponed, and whether it might be postponed indefinitely.Humans are certainly living longer. An American child born in 1970 could expect to live 70.8 years. By 2000, that had increased to 77 years. Moreover, an adult still alive at the age of 75 in 2002 could expect a further 11.5 years of life.Much of this change has been the result of improved nutrition and better medicine. But to experience a healthy old age also involves maintaining physical and mental function. Age-related non-pathological changes in the brain, muscles, joints, immune system, lungs and heart must be minimised. These changes are called “senescence”.Research shows that exercise can help to maintain physical function late in life and that exercising one's brain can limit the progression of senescence. Other work—on the effects of caloric restriction, consuming red wine and altering genes in yeast, mice and nematodes—has shown promise in slowing senescence.The approach advocated by Aubrey de Grey of the University of Cambridge, in England, and presented at last week's meeting of the American Association for the Advancement of Science, is rather more radical. As an engineer, he favours intervening directly to repair the changes in the body that are caused by ageing. This is an approach he dubs “strategies for engineered negligible senescence”. In other words, if ageing humans can be patched up for 30 years, he argues, science will have developed sufficiently to make further repairs more effective, postponing death indefinitely.Dr de Grey's ideas, which are informed by literature surveys rather than experimental work, have been greeted with scorn by those working at developing such repair kits. Steven Austad, a gerontologist based at the University of Texas, warns that such therapies are many years away and may never arrive at all. There are also the side effects to consider. While mice kept onlow-calorie diets live longer than their fatter friends, the skinny mice are less fertile and are sometimes sterile. Humans wishing both to prolong their lives and to procreate might thus wish to wait until their child-bearing years were behind them before embarking on such a diet, although, by then, relatively more age-related damage will have accumulated.No one knows exactly why a low-calorie diet extends the life of mice, but some researchers think it is linked to the rate at which cells divide. There is a maximum number of times that a human cell can divide (roughly 50) before it dies. This is because the ends of chromosomes, structures called telomeres, shorten each time the cell divides. Eventually, there is not enough left for any further division.Cell biologists led by Judith Campisi at the Lawrence Berkeley National Laboratory in California doubt that every cell has this dividing limit, and believe that it could be only those cells that have stopped dividing that cause ageing. They are devising an experiment to create a mouse in which senescent cells—those that no longer divide—are prevented from accumulating. They plan to activate a gene in the mouse that will selectively eliminate senescent cells. Such a mouse could demonstrate whether it is。

A survey published this week by the National Law Journal found that they now go as high as 1,800.美国法律期刊刊登的一项调查表明，现在的律师费用已经高达1800美元/时，But the general counsels of large businesses are increasingly finding that they can ignore these extravagant rates, and insist on big discounts.但是那些为大公司效力的法律顾问却逐渐发现，他们忽视高额酬金，并坚持较大折扣。

Price-discounting tends to be associated more with used-car lots than with posh law firms.There was a time when a lawyer could submit his bill and be confident of receiving a cheque for the same amount.价格折扣渐渐常见于二手车交易，并非光鲜的律师律师事务所。

TEXT 1Rebuilding the American dream machine重建美国梦机器Jan 19th 2006 | NEW YORKFrom The Economist print editionFOR America's colleges, January is a month ofreckoning. Most applications for the next academicyear beginning in the autumn have to be made by theend of December, so a university's popularity is put toan objective standard: how many people want toattend. One of the more unlikely offices to have beenflooded with mail is that of the City University ofNew Y ork (CUNY), a public college that lacks,among other things, a famous sports team, bucoliccampuses and raucous parties (it doesn't even havedorms), and, until recently, academic credibility.对美国的大学而言，一月是一个清算的月份。

大多数要进入将于秋季开学的下一学年学习的申请必须在12月底前完成，因此一所大学的声望就有了客观依据：申请人的多少。

纽约城市大学，一所公立学院，与其他学校相比，它没有一支声名显赫的运动队，没有田园诗一般的校园，也没有喧嚣嘈杂的派对——甚至连宿舍都没有，而且，直到最近也没取得学术上的可信度，可就是这所大学的办公室塞满了学生们寄来的申请函，这简直有些令人难以置信。

Stuff of dreams梦想的精粹（译者注：本文是关于画展的评论。

）Two exhibitions show how a pair of 18th-century painters, James Barry and Henry Fuseli, inspired the modern visual ★romance with[1] the gothic两个画展展示的是，两位18世纪画家——詹姆斯•巴里和亨利•富塞利——如何唤起了现代人从视觉上对哥特式艺术的憧憬。

THIS spring the bad boys of British art are ★making a comeback[2]. Not Damien Hirst and his friends, but the original ★enfants terribles[3]—★Henry Fuseli[4] (1741-1825) and James Barry (1741-1806)—who aimed, above all, to depict extremes of passion and terror in what they called the new art of the Sublime.今春，英国艺术界的坏孩子再次粉墨登场了。

我们说的不是达米恩•赫斯特和他的朋友们，而是亨利•富塞利（1741-1825）和詹姆斯•巴里（1741-1806），这两位“莽撞少年”的始作俑者，他们的首要目标就是要用所谓的“新派高尚艺术”去描绘极度激情与恐怖。

Barry and Fuseli are hardly household names; indeed since Victorian times they have been virtually ignored. But in the late 18th century, Fuseli, and for a short time Barry also, were prominent members of the young Royal Academy of Arts (RA) and influential professors of painting there. Barry's ★fall from grace[5] was the most dramatic, but there is much to admire in this irascible Irish artist who, like Fuseli, once taught William Blake. Barry's prolific historical paintings demonstrate his ambition to rival the painters of antiquity and the Renaissance and to practise what the then president of the RA, Sir Joshua Reynolds, always preached—that history painting was the noblest form of art. （1）But Barry found it hard to be bound by rules, and he turned history and myth into a series of ★tableaux[6] that were at once oddly expressionistic and deeply personal.巴里和富塞利这两个名字算不上家喻户晓，实际上自维多利亚时代以来，世人对他们已经不闻不问。

Which of the following are factors of production? Capital and Land2. Which of the following is an example of using physical capital to save time and money? Building extra space in a factory to simplify production3. To what part of an industry does a worker’s education contribute? Human capital4. Which of the following is an entrepreneur? a person who starts an all-organic cleaning supplies business that employs others5. What is the difference between a shortage and scarcity? A shortage can be temporary or long-term, but scarcity always exists.6. What does an economist mean by the term land? All natural resources used to produce goods and servicesSection 1.2 – Opportunity CostMaking Economic Decisions●The most desirable of the options you pass up is called the Opportunity Cost●Rank sleep, studying, and playing video games 1st, 2nd, and 3rd on a list for whatyou value the most●1st Place is what you would choose to do●2nd Place is your opportunity cost (you give it up to do option 1)What other option do you have other than using 3 hours for one task?●You could split your time among multiple activities!●Thinking at the Margin –decision involving adding one unit and subtractingone unit, rather than all or nothing●There is a point at which you are paying the same increase in cost, but seeinglower benefits●You must make the decision as to whether the cost is worth it●This same process is used by businesses and consumers to make decisions Quiz Review1. The economic concept of guns or butter means that? a government must decide whether to produce more or less military or consumer goods2. If a person who wants to buy a compact disc (CD) has just enough money to buy one, and chooses CD A instead of CD B, then CD B is the opportunity cost3. A decision-making grid is a visual way of: examining opportunity costs.4.

A production possibilities curve shows the relationship between the productions of: any two categories of goods2. The line on a production possibilities curve showing the relative amounts of two types of goods produced using all resources is called the production possibilities frontier3. The law of increasing costs means that as production shifts from one item to another, more and more resources are necessary to increase production of the second item4. The curve usually seen in a production possibilities frontier can be explained by: the law of increasing costsAn economy that is efficient is producing the maximum amount of goods and services.。

经济学家》读译参考（第12篇）:并非科幻小说——《直觉》畅销书书评From The Economist print edition[size=4][b]Not science fictionTHE recent stem-cell scandal in South Korea may have made front-page news across the world, but（1）few readers are likely to bet that a literary novel set in a laboratory and based on scientific research might end up being a ★page-turner[1]. Readers of “Intuition”, however, will battle with themselves over whether to savour Allegra Goodman's exquisite★filleting[2] of character, as the scientists are themselves dissected like their experimental mice, or to rush ★headlong[3] to find out what h________① next.In an under-funded Harvard laboratory, the ★dogged[4], unglamorous★slog[5] towards finding a cure for cancer is u_______② way. Suddenly one research assistant's experiment ★bears [6]fruit. After mice infected with human breast-cancer cells are injected with Cliff's R-7 virus, their tumours melt away in 60% of the population. But are Cliff's results too good to be true? （2）The question of whether the R-7 results were★fiddled[7] powers the remainder of the book.Ms Goodman follows the good novelist's ★credo[8] that plot ★proceeds from[9] character; and （3）she follows the good scientist's credo that objective truth is inexorably ★coloured[10] by whoever ★stands[11] to lose or gain by it. All the researchers in “Intuition” are sympathetic, and they are all ★screwed up[12]. Sandy, co-director of the lab, is a ★charismatic[13] dynamo[14], but too enamoured with worldly glory. His brilliant, shy partner Marion has ★impeccable[15] research standards, but is undermined by chronic self-doubt. By contrast, Cliff is ★glibly[16] over-c_________③. Robin, R-7's ★whistle-blower[17] (also Cliff's former girlfriend), is a natural scientist, but her determination to uncover fraud may be driven by romantic disappointment. Robin is heeding her intuition, and “young researchers had their intuition ★tamped down[18] lest, like the ★sorcerer's[19] apprentice, they flood the lab with their conceits.”What a relief to find a novel that does not take place in the literary salons of London or New York. （4）Ms Goodman manages fully to inhabit another profession's world. Her characters so live and breathe on the page that they could get up and m_______④you a cup of coffee while you finish another chapter. （5）Her writing is rich, so rich it would be easy tomiss how skilful is the prose itself. Exciting and, for most, exotic as well, “Intuition” is a ★stunning[20] achieve ment.参考译文（TRANSLATED BY CHENJILONG）并非科幻小说韩国最近发生的干细胞丑闻或许已成为世界各地的头条新闻，不过几乎没有读者会相信，一本以实验室为背景、基于科学研究的小说到头来竟然让他们爱不释手。

还算公道——中美洲咖啡与“啡农”Fair enough（还算公道）MAKING good coffee is not a simple business. Coffee bushes must be grown in shade—neither too much, nor too little. A hillside is best—but it mustn't be too s______①. After three years, the bushes will start to produce bright-red coffee “cherries”, which are picked, processed to remove the pulp, and spread out to dry for days, ideally on concrete. They are m_______②again to separate the bean, which needs to rest, preferably for a few months. （1）Only then can it be roasted, ground and brewed into the stuff that dreams are ★quelled with[1].In Mexico and parts of Central America, as in Colombia and Peru further south but not in Brazil, most coffee farmers are smallholders. （2）They found it especially hard to deal with the recent ★slump[2] in the coffee price. The price has since recovered: the benchmark price applied to m________③ coffee now ranges from $1.11 to $1.14 per pound. That is roughly double its ★rock-bottom[3] level of August 2002.But the v_________④ of their income makes it hard for farmers to invest to sustain their crop, says Fernando Celis of the Mexican National Organisation of Coffee Growers. The slump forced many small farmers to switch to other crops, or migrate to cities. Mexico's exports of coffee are less than half of what they were six years ago.（3）For farmers, one way out of this dilemma is to decouple the price they are paid from the international commodities markets. This is the a_______⑤ of Fairtrade, a London-based organisation which certifies products as “responsibly” sourced. Fairtrade determines at what price farmers make what it considers a reasonable profit. Its current calculation is that the appropriate figure is 10% above the market price.W________⑥, sales of Fairtrade-certified coffee have increased from $22.5m per year to $87m per year since 1998. This is still only a tiny fraction of the overall world coffee trade, worth $10 billion annually. But there are plenty of other ★niche markets[4] for high-quality coffee. Some small producers can c_________⑦ more by marketing their coffee as organic—a switch which takes five years or so—or “bird-friendly” （4）because, unlike large, mechanised plantations, they have retained shade trees.Starbucks, the Seattle-based coffee-bar c________⑧, says it uses a similar formula to that of Fairtrade in buying its coffee. All is bought at a “fair price”, says Peter Torrebiarte, who manages Starbucks' buying operation in Costa Rica.（5）Some niches can be large. Only 6% of world o________⑨ is of top quality, but in Costa Rica and Guatemala the figure rises to 60%, says Mr Torrebiarte. Starbucks bought 37% of Costa Rica's entire coffee crop in the 2004-05 season, according to Adolfo Lizano of the country's coffee institute.Mexico lags behind its neighbours in extracting higher prices. But 95% of the coffee in Mexico is arabica—the type of bean demanded by connoisseurs—rather than lower-grade robusta. Almost all of it is grown at a________⑩, which also improves quality. So Mexico, too, has the potential to compete on quality rather than price. Only by following the path forged by Costa Rica and Guatemala, says Mr Celis, can Mexico's coffee growers survive in the world market. （6）For their part, discerning coffee drinkers can satisfy their palate and their conscience at the same time.[QUIZ]（下列2题任选其一即可，认真答题者即给予80沪元奖励。
