TheEconomist《经济学人》常用
《Economist》常用词汇总结
◆The Economist 《经济学人》常用原理解释●蝴蝶效应:上个世纪70年代，美国一个名叫洛伦兹的气象学家在解释空气系统理论时说，亚马逊雨林一只蝴蝶翅膀偶尔振动，也许两周后就会引起美国得克萨斯州的一场龙卷风。
蝴蝶效应是说，初始条件十分微小的变化经过不断放大，对其未来状态会造成极其巨大的差别。
有些小事可以糊涂，有些小事如经系统放大，则对一个组织、一个国家来说是很重要的，就不能糊涂。
●鳄鱼法则：其原意是假定一只鳄鱼咬住你的脚，如果你用手去试图挣脱你的脚，鳄鱼便会同时咬住你的脚与手。
你愈挣扎，就被咬住得越多。
所以，万一鳄鱼咬住你的脚，你唯一的办法就是牺牲一只脚。
譬如在股市中，鳄鱼法则就是：当你发现自己的交易背离了市场的方向，必须立即止损，不得有任何延误，不得存有任何侥幸。
●鲇鱼效应：以前，沙丁鱼在运输过程中成活率很低。
后有人发现，若在沙丁鱼中放一条鲇鱼，情况却有所改观，成活率会大大提高。
这是何故呢?原来鲇鱼在到了一个陌生的环境后，就会“性情急躁”，四处乱游，这对于大量好静的沙丁鱼来说，无疑起到了搅拌作用;而沙丁鱼发现多了这样一个“异已分子”，自然也很紧张，加速游动。
这样沙丁鱼缺氧的问题就迎刃而解了，沙丁鱼也就不会死了。
●羊群效应：头羊往哪里走，后面的羊就跟着往哪里走。
羊群效应最早是股票投资中的一个术语，主要是指投资者在交易过程中存在学习与模仿现象，“有样学样”，盲目效仿别人，从而导致他们在某段时期内买卖相同的股票。
●刺猬法则：两只困倦的刺猬，由于寒冷而拥在一起。
可因为各自身上都长着刺，于是它们离开了一段距离，但又冷得受不了，于是凑到一起。
几经折腾，两只刺猬终于找到一个合适的距离：既能互相获得对方的温暖而又不至于被扎。
刺猬法则主要是指人际交往中的“心理距离效应”。
●手表定律：手表定律是指一个人有一只表时，可以知道现在是几点钟，而当他同时拥有两只时却无法确定。
两只表并不能告诉一个人更准确的时间，反而会使看表的人失去对准确时间的信心。

2013厦门大学考研状元笔记 金融学 考研复试 英语词汇
育明教育【温馨提示】现在很多小机构虚假宣传，育明教育咨询部建议考生一定要实地考察，并一定要查看其营业执照，或者登录工商局网站查看企业信息。
目前，众多小机构经常会非常不负责任的给考生推荐北大、清华、北外等名校，希望广大考生在选择院校和专业的时候，一定要慎重、最好是咨询有丰富经验的考研咨询师！the Economist 《经济学人》常用词汇总结育明教育解析：这一部分，对于准备考研英语和专业课复习会有一定的帮助。
101、市场（Market）市场是指为了买和卖某些商品而与其他厂商和个人相联系的一群厂商和个人。
102、市场需求曲线（Market demand curve）市场需求曲线表示在整个市场中产品的价格和它的需求量之间的关系。
103、市场周期（Market period）市场周期是指一种商品的供给量保持不变的一段时期。
104、市场结构（ Market structure）四种一般的市场类型是完全竞争、垄断、垄断竞争和寡头垄断。
一个市场的结构依赖于买者和卖者的数量以及产品差别的大小。
105、市场供给表（ Market supply schedule）市场供给表表示在各种价格下一种商品所能够供给的数量。
106、加成定价（Markup pricing）加成定价是指，为了确定一种产品的价格而把一个百分比（或绝对的）数量加到所估计的产品平均（或边际的）成本上，这就意味着该数量要计入某些无法化归任何具体产品中去的成本，并且旨在维持厂商的某一投资回报率。
107、最大最小策略（Maximin strategy)最大最小策略是指局中人使得能够获得的最小收益最大化的策略。
108、微观经济学（Microeconomics）微观经济学是经济学的一部分，它分析像消费者、厂商和资源所有者这些个体的经济行为（宏观经济学与之相反，它分析像国内总产品这样的经济总体行为）。
109、工厂的最小有效规模（Minimum efficient size of plant）在长期中平均成本处于或接近其最小值的最小的工厂规模。
2013北京外国语大学考研状元笔记 金融学 考研复试 英语词汇
官方网址 北大、人大、中财、北外教授创办 集训营、一对一保分、视频、小班、少干、强军 北京外国语大学the Economist 《经济学人》常用词汇总结育明教育解析：这一部分，对于准备考研英语和专业课复习会有一定的帮助。
387、Excise tax vs ． sales tax 消费税和销售税消费税是对某种或某组商品，如酒和烟草的购买所课征的税。
销售税是对除少数特定商品（如食品）以外的所有商品所课征的税。
388、Exclusion principle 排他原则私人品区别于公共品的一种性质。
当生产者将一种商品卖给A 后，若能很容易地将B 、C 、D 等人排除在该商品益处享用过程之外，则排他原则就在发生作用，该商品也因此是一项私人品。
若不能轻易地把其他人排除在分享过程之外，如公共卫生或国防，则我们称该商品具有公共品的特征。
389、Exogenous vs ． induced variables 外生变量和引致变量外生变量是那些由经济体系以外的因素来决定的变量。
与外生变量相对应的是引致变量，后者是由经济体系的内在运行所决定的。
例如，天气变化是外生变量，而消费的变化则常常由收入变动所引致。
390、Expectations 预期对于不确定因素（如未来利率、价格或税率）的看法或意见。
如果预期没有系统性错误（或偏差）并应用了所有可能获得的信息，则称为理性的（rational ）预期。
如果人们根据过去的行为来形成他们的预期，则这种预期称为是适应性的（adaptive ）。
391、Expenditure multiplier 支出乘数参见乘数（multiplier ）。
392、Exports 出口在本国生产而卖给别国的商品或服务。
包括商品（如汽车）、服务（如运输）和贷款及投资的利息。
进口正好是一种反方向的流动--商品和服务从别国流入本国。
393、External diseconomies 外部不经济指生产或消费给其他人造成损失而其他人却不能得到补偿的情况。
TheEconomist《经济学人》常用词汇总结
The Economist《经济学人》常用词汇总结1、绝对优势(Absolute advantage)如果一个国家用一单位资源生产的某种产品比另一个国家多，那么，这个国家在这种产品的生产上与另一国相比就具有绝对优势。
2、逆向选择(Adverse choice)在此状况下，保险公司发现它们的客户中有太大的一部分来自高风险群体。
3、选择成本(Alternative cost)如果以最好的另一种方式使用的某种资源，它所能生产的价值就是选择成本，也可以称之为机会成本。
4、需求的弧弹性(Arc elasticity of demand)如果P1和Q1分别是价格和需求量的初始值，P2和Q2为第二组值，那么，弧弹性就等于-(Q1-Q2)(P1+P2)/(P1-P2)(Q1+Q2)5、非对称的信息(Asymmetric information)在某些市场中，每个参与者拥有的信息并不相同。
例如，在旧车市场上，有关旧车质量的信息，卖者通常要比潜在的买者知道得多。
6、平均成本(Average cost)平均成本是总成本除以产量。
也称为平均总成本。
7、平均固定成本(Average fixed cost)平均固定成本是总固定成本除以产量。

TheEconomist经济学人高频词汇详解汇总
TheEconomist经济学人高频词汇详解汇总1、绝对优势(Absolute advantage)如果一个国家用一单位资源生产的某种产品比另一个国家多，那么，这个国家在这种产品的生产上与另一国相比就具有绝对优势。
2、逆向选择(Adverse choice)在此状况下，保险公司发现它们的客户中有太大的一部分来自高风险群体。
3、选择成本(Alternative cost)如果以最好的另一种方式使用的某种资源，它所能生产的价值就是选择成本，也可以称之为机会成本。
4、需求的弧弹性( Arc elasticity of demand)如果P1和Q1分别是价格和需求量的初始值，P2 和Q2 为第二组值，那么，弧弹性就等于 -(Q1-Q2)(P1，P2)/(P1-P2)(Q1，Q2)5、非对称的信息(Asymmetric information)在某些市场中，每个参与者拥有的信息并不相同。
例如，在旧车市场上，有关旧车质量的信息，卖者通常要比潜在的买者知道得多。
6、平均成本(Average cost)平均成本是总成本除以产量。
也称为平均总成本。
7、平均固定成本( Average fixed cost)平均固定成本是总固定成本除以产量。

全国气候：政治搭台，科学唱戏Climate change 气候变化heated debate 激辩Nov 26th 2009From The Economist print editionWhy political orthodoxy must not silence scientific argument为何有了政治说法，还应有科学的辩论？Illustration by Claudio Munoz“WHAT is truth?” That was Pontius Pilate’s answer to Jesus’s assertion that “Everyone that is of the truth heareth my voice.” It sounds suspiciously like the modern argument over climate change.“真理是什么？”耶稣说完“相信真理的人都能听到我”之后，彼拉多随即如此问道。
听起来耳熟？在当代，气候变化引起的争辩就与此有相似之处。
A majority of the world’s climate sc ientists have convinced themselves, and also a lot of laymen, some of whom have political power, that the Earth’s climate is changing; that the change, from humanity’s point of view, is for the worse; and that the cause is human activity, in the form of excessive emissions of greenhouse gases such as carbon dioxide.国际上，大多数气候科学家不但说服了自己，也说服了很多门外汉（其中包括一些有政治影响力的人）--地球的气候正在改变；这种改变，从人道主义角度来看，是消极的；这种改变的始作俑者是人类，是他们通过排放超量的诸如二氧化碳的温室气体而造成的。
《经济学人》杂志原版英文(The Economist整理版4-5)
Digest Of The. Economist. 2006(4-5)Hot to trotA new service hopes to do for texting what Skype did for voice callsTALK is cheap—particularly since the appearance of voice-over-internet services such as Skype. Such services, which make possible very cheap (or even free) calls by routing part or all of each call over the internet, have forced traditional telecoms firms to cut their prices. And now the same thing could be about to happen to mobilephone text messages, following the launch this week of Hotxt, a British start-up.Users download the Hotxt software to their handsets, just as they would a game or a ringtone. They choose a user name, and can then exchange as many messages as they like with other Hotxt users for £1 ($1.75) per week. The messages are sent as data packets across the internet, rather than being routed through operators' textmessaging infrastructure. As a result, users pay only a tiny data-transport charge, typically of a penny or so per message. Since text messages typically cost 10p, this is a big saving—particularly for the cost-conscious teenagers at whom the service is aimed.Most teenagers in Britain, and elsewhere in Europe, pay for their mobile phones on a “pre-paid” basis, rather than having a monthly contract with a regular bill. Pre-paid tariffs are far more expensive: bundles of free texts and other special deals, which can reduce the cost of text messaging, are generally not available. For a teenager who sends seven messages a day, Hotxt can cut the cost of texting by 75%, saving £210 per year, says Doug Richard, the firm's co-founder. For really intensive text-messagers, the savings could be even bigger: Josh Dhaliwal of mobileYouth, a market-research firm, says that some teenagers—chiefly boys aged 15-16 and girls aged 14-15—are “supertexters” who send as many as 50 messages per day.While this sounds like good news for users, it could prove painful for mobile operators. Text-messaging accounts for around 20% of a typical operator's revenues. With margins on text messages in excess of 90%, texting also accounts for nearly half of an operator's profits. Mr Richard is confident that there is no legal way that operators can block his service; they could raisedata-transport costs, but that would undermine their own efforts to push new services. Hotxt plans to launch in other countries soon.“The challenge is getting that initial momentum,” says Mr Dhaliwal. Hotxt needs to persuade people to sign up, so that they will persuade their friends to sign up, and so on. Unlike Skype, Hotxt is not free, so users may be less inclined to give it a try. But as Skype has also shown, once a disruptive, low-cost communications service starts to spread, it can quickly become very big indeed. And that in turn can lead to lower prices, not just for its users, but for everyone.A discerning viewA new way of processing X-rays gives much clearer imagesX-RAYS are the mysterious phenomenon for which Wilhelm Röntgen was awarded the first Nobel prize in physics, in 1901. Since then, they have shed their mystery and found widespread use in medicine and industry, where they are used to revealthe inner properties of solid bodies.Some properties, however, are more easily discerned than others. Conventional Xray imaging relies on the fact that different materials absorb the radiation to different degrees. In a medical context, for example, bones absorb X-rays readily, and so show up white on an X-radiograph, which is a photographic negative. But Xrays are less good at discriminating between different forms of soft tissue, such as muscles, tendons, fat and blood vessels. That, however, could soon change. For Franz Pfeiffer of the Paul Scherrer Institute in Villigen, Switzerland, and his colleagues report, in the April edition of Nature Physics, that they have manipulated standard X-ray imaging techniques to show many more details of the inner body.The trick needed to discern this fine detail, according to Dr Pfeiffer, is a simple one. The researchers took advantage not only of how tissues absorb X-rays but also of how much they slow their passage. This slowing can be seen as changes in the phase of the radiation that emerges—in other words of the relative positions of the peaks and troughs of the waves of which X-rays are composed.Subtle changes in phase are easily picked up, so doctors can detect even small variations in the composition of the tissue under investigation, such as might be caused by the early stages of breast cancer. Indeed, this trick—known as phase-contrast imaging—is already used routinely in optical microscopy and transmission electron microscopy. Until now, however, no one had thought to use it for medical X-radiography.To perform their trick, the researchers used a series of three devices called transmission gratings. They placed one between the source of the X-rays and the body under examination, and two between the body and the X-ray detector that forms the image. The first grating gathers information on the phases of the X-rays passing through it. The second and third work together to produce thedetailed phase-contrasted image. The approach generates two separate images—the classic X-ray image and the phase-contrasted image—which can then be combined to produce a high-resolution picture.The researchers tested their technique on a Cardinal tetra, a tiny iridescent fish commonly found in fish tanks and aquariums. The conventional X-ray image showed the bones and the gut of the fish, while the phase-contrasted image showed details of the fins, the ear and the eye.Dr Pfeiffer's technique would thus appear to offer a way to get much greater detail for the same amount of radiation exposure. Moreover, since it uses standard hospital equipment, it should be easy to introduce into medical practice. X-rays may no longer be the stuff of Nobel prizes, but their usefulness may just have increased significantly.Here be dragonsWith luck, you may soon be able to buy a mythological petPAOLO FRIL, chairman and chief scientific officer of GeneDupe, based in San Melito, California, is a man with a dream. That dream is a dragon in every home.GeneDupe's business is biotech pets. Not for Dr Fril, though, the mundane cloning of dead moggies and pooches. He plans a range of entirely new animals—or, rather, of really quite old animals, with the twist that even when they did exist, it was only in the imagination.Making a mythical creature real is not easy. But GeneDupe's team of biologists and computer scientists reckon they are equal to the task. Their secret is a new field, which they call “virtual cell biology”.Biology and computing have a lot in common, since both are about processing information—in one case electronic; in the other, biochemical. Virtual cell biology aspires to make a software model of a cell that is accurate in every biochemical detail. That is possible because all animal cells use the same parts list—mitochondria for energy processing, the endoplasmic reticulum for making proteins, Golgi body for protein assembly, and so on.Armed with their virtual cell, GeneDupe's scientists can customise the result so that it belongs to a particular species, by loading it with a virtual copy of that animal's genome. Then, if the cell is also loaded with the right virtual molecules, it will behave like a fertilised egg, and start dividing and developing—first into an embryo, and ultimately into an adult.Because this “growth” is going on in a computer, it happens fast. Passing from egg to adult in one of GeneDupe's enormous Mythmaker computers takes less than a minute. And it is here that Charles Darwin gets a look in. With such a short generation time, GeneDupe's scientists can add a little evolution to their products.Each computer starts with a search image (dragon, unicorn, gryphon, etc), and the genome of the real animal most closely resembling it (a lizard for the dragon, a horse for the unicorn and, most taxingly, the spliced genomes of a lion and an eagle for the gryphon). The virtual genomes of these real animals are then tweaked by random electronic mutations. When they have matured, the virtual adults most closely resembling the targets are picked and cross-bred, while the others are culled.Using this rapid evolutionary process, GeneDupe's scientists have arrived at genomes for a range of mythological creatures—in a computer, at least. The next stage, on which they are just embarking, is to do it for real.This involves synthesising, with actual DNA, the genetic material that the computer models predict will produce the mythical creatures. The synthetic DNA is then inserted into a cell that has had its natural nucleus removed. The result, Dr Fril and his commercial backers hope, will be a real live dragon, unicorn or what have you.Tales of the unexpectedWhy a drug trial went so badly wrongIN ANY sort of test, not least a drugs trial, one should expect the unexpected. Even so, on March 13th, six volunteers taking part in a small clinical trial of a treatment known as TGN1412 got far more than they bargained for. All ended up seriously ill, with multiple organ failure, soon after being injected with the drug at a special testing unit at Northwick Park Hospital in London, run by a company called Parexel. One man remains ill in hospital.Small, preliminary trials of this sort are intended to find out whether a drug is toxic. Nevertheless, the mishap was so serious that Britain's Medicines and Healthcare products Regulatory Agency (MHRA), a government body, swiftly launched a full inquiry. On April 5th it announced its preliminary findings. These were that the trial was run correctly, doses of the drug were given as they were supposed to have been, and there was no contamination during manufacturing. In other words, it seems that despite extensive tests on animals and human-cell cultures, and despite the fact that the doses in the human trial were only a five-hundredth of those given to the animals, TGN1412 is toxic in people in a way that simply had not shown up.This is a difficult result for the drug business because it raises questions about the right way of testing medicines of this kind. TGN1412 is unusual in that it is an antibody. Most drugs are what are known as “small molecules”. Antibodies are big, powerful proteins that are the workhorses of the immune system. A mere 20 of them have been approved for human therapy, or are in latestage clinical trails, in America and Europe, but hundreds are in pre-clinical development, and will soon need to be tried out on people.Most antibody drugs are designed to work in one of three ways: by recruiting parts of the immune system to kill cancer cells; by delivering a small-molecule drug or a radioactive atom specifically to a cancer; or by blocking unwanted immune responses. In that sense, TGN1412 was unusual because it worked in a fourth way. It is what is called a “superagonistic” antibody, designed to increase the numbers of a type of immune cell known as regulatory T-cells.Reduced numbers, or impaired function, of regulatory T-cells has been implicated in a number of illnesses, such as type 1 diabetes, multiple sclerosis and rheumatoid arthritis. Boosting the pool of these antibodies seemed like a good treatment strategy. Unfortunately, that strategy fell disastrously to pieces and it will take a little longer to find out why.The result highlights concerns raised in a paper just published by the Academy of Medical Sciences, a group of experts based in London. It says there are special risks associated with novel antibody therapies. For example, their chemical specificity means that they might not bind to their targets in humans as they do in other species.Accidence and substanceTwo possible explanations for the bulk of realityTHE unknown pervades the universe. That which people can see, with the aid of various sorts of telescope, accounts for just 4% of the total mass. The rest, however, must exist. Without it, galaxies would not survive and the universe would not be gently expanding, as witnessed by astronomers. What exactly constitutes this dark matter and dark energy remains mysterious, but physicists have recently uncovered some more clues, about the former, at least.One possible explanation for dark matter is a group of subatomic particles called neutrinos. These objects are so difficult to catch that a screen made of lead a light-year thick would stop only half the neutrinos beamed at it from getting through. Yet neutrinos are thought to be the most abundant particles in the universe. Some ten thousand trillion trillion—most of them produced by nuclear reactions in the sun—reach Earth every second. All but a handful pass straight through the planet as if it wasn't there.According to the Standard Model, the most successful description of particle physics to date, neutrinos come in three varieties, called “flavours”. These are known as electron neutrinos, tau neutrinos and muon neutrinos. Again, according to the Standard Model, they are point-like, electrically neutral and massless. But in recent years, this view has been challenged, as physicists realised that neutrinos might have mass.The first strong evidence came in 1998, when researchers at an experiment called SuperKamiokande, based at Kamioka, in Japan, showed that muon neutrinos produced by cosmic rays hitting the upper atmosphere had gone missing by the time they should have reached an underground detector. SuperKamiokande's operators suspect that the missing muon neutrinos had changed flavour, becoming electron neutrinos or—more likely—tau neutrinos. Theory suggests that this process, called oscillation, can happen only if neutrinos have mass.Since then, there have been other reports of oscillation. Results from the Sudbury Neutrino Observatory in Canada suggest that electron neutrinos produced by nuclear reactions in the sun change into either muon or tau neutrinos on their journey to Earth. Two other Japanese experiments, one conducted at Kamioka and one involving the KEK particle-accelerator laboratory in Tsukuba, near Tokyo, also hint at oscillation.Last week, researchers working on the MINOS experiment at Fermilab, near Chicago, confirmed these results. Over the coming months and years, they hope to produce the most accurate measurements yet. The researchers created a beam of muon neutrinos by firing an intense stream of protons into a block of carbon. On the other side of the target sat a particle detector that monitored the number of muon neutrinos leaving the Fermilab site. The neutrinos then traveled 750km (450 miles) through the Earth to a detector in a former iron mine in Soudan, Minnesota.Myths and migrationDo immigrants really hurt American workers' wages?EVERY now and again America, a nation largely made up of immigrants and their descendants, is gripped by a furious political row over whether and how it should stem the flood of people wanting to enter the country. It is in the midst of just such a quarrel now. Congress is contemplating the erection of a wall along stretches of the Mexican border and a crackdown on illegalworkers, as well as softer policies such as a guest-worker programme for illegal immigrants. Some of the arguments are plain silly. Immigration's defenders claim that foreigners come to do jobs that Americans won't—as if cities with few immigrants had no gardeners. Its opponents say that immigrants steal American jobs—succumbing to the fallacy that there are only a fixed number of jobs to go around.One common argument, though not silly, is often overstated: that immigration pushes down American workers' wages, especially among high-school dropouts. It isn't hard to see why this might be. Over the past 25 years American incomes have become less equally distributed, typical wages have grown surprisingly slowly for such a healthy economy and the real wages of the least skilled have actually fallen. It is plausible that immigration is at least partly to blame, especially because recent arrivals have disproportionately poor skills. In the 2000 census immigrants made up 13% of America's pool of workers, but 28% of those without a high-school education and over half of those with eight years' schooling or less.In fact, the relationship between immigration and wages is not clear-cut, even in theory. That is because wages depend on the supply of capital as well as labour. Alone, an influx of immigrants raises the supply of workers and hence reduces wages. But cheaper labour increases the potential return to employers of building new factories or opening new valet-parking companies. In so doing, they create extra demand for workers. Once capital has fully adjusted, the final impact on overall wages should be a wash, as long as the immigrants have not changed the productivity of the workforce as a whole.However, even if wages do not change on average, immigration can still shift the relative pay of workers of different types. A large inflow of low-skilled people could push down the relative wages of low-skilled natives, assuming that they compete for the same jobs. On the other hand, if the immigrants had complementary skills, natives would be relatively better off. To gauge the full effect of immigration on wages, therefore, you need to know how quickly capital adjusts and how far the newcomers are substitutes for local workers.Roaming holidayThe EU hopes to slash the price of cross-border mobile calls“TODAY it is only when using your mobile phone abroad that you realise there are still borders in Europe,” lamented Viviane Reding, the European commissioner responsible for telecoms and media regulation, as she announced plans to slash the cost of mobile roaming last month. It is a laudable aim: European consumers typically pay €1.25 ($1.50) per minute to call home from another European country, and €1 per minute to receive calls from home while abroad. With roaming margins above 90%, European mobile operators make profits of around €10 billion a year from the trade, the commission estimates.Ms Reding's plan, unveiled on March 28th and up for discussion until May 12th, is to impose a “home pricing” scheme. Even while roaming, callers would be charged whatever they would normally pay to use their phones in their home countries; charges for incoming calls while roaming would be abolished. That may sound good. But, as the industry is understandably at pains to point out, it could have some curious knock-on effects.In particular, consumers could sign up with operators in foreign countries to take advantage of lower prices. Everyone would take out subscriptions to the cheapest supplier and bring them back home, says John Tysoe of the Mobile World, a consultancy. “You'd end up with a complete muddle. An operator might have a network, bu t no customers, because they've all migrated.”Another problem with Ms Reding's plan, he says, is that operators would compensate for the loss of roaming fees— thought to account for around 3% of their revenues and 5% of profits—by raising prices elsewhere. This would have the perverse effect of lowering prices for international business travellers, a big chunk of roaming traffic, while raising prices for most consumers.The commission's proposals are “economically incoherent”, says Richard Feasey of Vodafo ne, which operates mobile networks in many European countries. Imposing price caps on roaming is legally questionable, he says, and Vodafone has, in any case, been steadily reducing its roaming charges. (European regulators prevented it from doing so for three years on antitrust grounds after its takeover of Mannesmann in 2000.) Orange, another multinational operator, says it is planning to make price cuts, too. “Of course, now everybody's got price cuts,” says Stefano Nicoletti of Ovum, a consultancy.But perhaps Ms Reding's unspoken plan is to use the threat of regulation as a way to prompt action. Operators are right that her proposals make no sense, but they are charging too much all the same. So expect them to lobby hard against the proposals over the next couple of years, while quietly cutting their prices—an outcome that would, of course, allow both sides to claim victory.Devices and their desiresEngineers and chemists get togetherTHERE used to be a world of difference between treating a patient with a device—such as a fake hip or a pacemaker—and using biology and biochemistry. Different ailments required wholly different treatments, often with little in common. But that is changing as medical advances—such as those being trumpeted at the biotechnology industry's annual gathering this week in Chicago—foster combinations of surgical implants and other hardware with support from medicines. Drug-releasing stents were one of the first fruits of this trend, which increasingly requires vastly different sorts of health-care firms to mesh their research efforts.That will be a challenge. While pharmaceutical and biotech firms are always in search of the next big thing, devicemakers prefer gradual progress. Instead of hanging out with breathless entrepreneurs near America's east and west coasts, where most drug and biotechnology firms are based, many of the device-makers huddle in midwestern cities such as Minneapolis, Indianapolis and Kalamazoo. And unlike Big Pharma, which uses marketing blitzes to tell ailing consumers about its new drugs, medical-device sales teams act more as instructors, showing doctors how to install their latest creations.Several companies, however, are now trying to bring these two business cultures together. Earlier this year, for example, Angiotech Pharmaceuticals, a Canadian firm, bought American Medical Instruments (AMI). Angiotech's managers reckon their company has devised a good way to apply drug coatings to all sorts of medical paraphernalia, from sutures and syringes to catheters, in order to reduce the shock to the body. AMI makes just the sorts of medical supplies to which Angiotech hopes to apply its techniques.One of America's biggest makers of medical devices, Medtronic, has been doing joint research with Genzyme, a biotechnology company that is also keen on broader approaches to health care. Genzyme says that it was looking for better ways to treat ailments, such as coronary and kidney disease, and realised that it needed to understand better how electro-mechanical devices and information technology work. But combining its efforts with those of Medtronic “on a cultural level is very hard”, the company says. Biotechnology firms are used to much more risky projects and far longer development cycles.Another difference is that device-makers know that if a problem emerges with their hardware, the engineers will tinker around and try to resolve the glitch. Biotech and pharmaceutical firms have no such option. If a difficulty emerges after years of developing and testing a new pill, as with Merck's Vioxx, there may be little they can do about it. “You can't futz with a molecule”, says Debbie Wang, a health-care industry analyst.Strangely, says Ms Wang, some of the most promising engineering outfits were once divisions of pharmaceutical andhealth-care companies, which got rid of them precisely because they did not appear to offer the rapid growth that managers saw in prescription drugs. Guidant, a maker of various cardiovascular devices, was spun off by Eli Lilly in 1994 and a decade later became the prize in a bidding war between Johnson & Johnson and Boston Scientific, which Boston won earlier this year.Pfizer sold Howmedica, which makes joint replacements and prosthetics, to Kalamazoo-based Stryker in 1998. Anotherjoint-replacement maker, Zimmer, was spun off from Bristol-Myers Squibb in 2001. Now both those companies are looking for ways to add “anti-interactive coatings”—ie, drugs—to their business. One of the most troublesome complications in joint replacement is infection.The big drug companies might be tempted to reacquire the firms that they let go. But, given the potential for cultural and strategic clashes, it may make more sense for a few big and broad medical-device makers, such as Medtronic, Boston Scientific and St Jude Medical, to continue consolidating their own industry while co-operating, along the lines of the Medtronic-Genzyme venture, with biotech and pharmaceutical firms as they see fit. There would still be irritation; but probably less risk of wholesale rejection.Eat less, live moreHow to live longer—maybeDIETING, according to an old joke, may not actually make you live longer, but it sure feels that way. Nevertheless, evidence has been accumulating since the 1930s that calorie restriction—reducing an animal's energy intake below its energy expenditure—extends lifespan and delays the onset of age-related diseases in rats, dogs, fish and monkeys. Such results have inspired thousands of people to put up with constant hunger in the hope of living longer, healthier lives. They have also led to a search for drugs that mimic the effects of calorie restriction without the pain of going on an actual diet.Amid the hype, it is easy to forget that no one has until now shown that calorie restriction works in humans. That omission, however, changed this month, with the publication of the initial results of the first systematic investigation into the matter. Thisstudy, known as CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy), was sponsored by America's National Institutes of Health. It took 48 men and women aged between 25 and 50 and assigned them randomly to either a control group or a calorie-restriction regime. Those in the second group were required to cut their calorie intake for six months to 75% of that needed to maintain their weight.The CALERIE study is a landmark in the history of the field, because its subjects were either of normal weight or only slightly overweight. Previous projects have used individuals who were clinically obese, thus confusing the unquestionable benefits to health of reducing obesity with the possible advantages of calorie restriction to the otherwise healthy.At a molecular level, CALERIE suggests these advantages are real. For example, those on restricted diets had lower insulin resistance (high resistance is a risk factor for type 2 diabetes) and lower levels of low-density lipoprotein cholesterol (high levels are a risk factor for heart disease). They showed drops in body temperature and blood-insulin levels—both phenomena that have been seen in long-lived, calorie-restricted animals. They also suffered less oxidative damage to their DNA.Eric Ravussin, of Louisiana State University in Baton Rouge, who is one of the study's authors, says that such results provide support for the theory that calorie restriction produces a metabolic adaptation over and above that which would be expected from weight loss alone. (He also points out that it will be a long time before such work reveals whether calorie restriction actually extends life.) Nevertheless, such metabolic adaptation could be the reason why calorie restriction is associated with longer lifespans in other animals—and that is certainly the hope of those who, for the past 15 years, have been searching for ways of triggering that metabolic adaptation by means other than semi-starvation.The search for a drug that will stave off old age is itself as old as the hills—as is the wishful thinking of the suckers who finance such efforts. Those who hope to find it by mimicking the effect of calorie restriction are not, however, complete snake-oil salesmen, for there is known to be a family of enzymes called sirtuins, which act both as sensors of nutrient availability and as regulators of metabolic rate. These might provide the necessary biochemical link between starving and living longer.Universal service?Proponents of “software as a service” say it will wipe out traditional softwareSOMETHING momentous is happening in the software business. Bill Gates of Mi crosoft calls it “the next sea change”. Analysts call it a “tectonic shift” in the industry. Trade publications hail it as “the next big thing”. It is software-as-a-service (SaaS)—the delivery of software as an internet-based service via a web browser, rather than as a product that must be purchased, installed and maintained. The appeal is obvious: SaaS is quicker, easier and cheaper to deploy than traditional software, which means technology budgets can be focused on providing competitive advantage, rather than maintenance.This has prompted an outbreak of iconoclasm. “Traditional software is dead,” says Jason Maynard, an analyst at Credit Suisse. Just as most firms do not own generators, but buy electricity from the grid, so in future they will buy software on the hoof, he says. “It's the end of software as we know it. All software is becoming a service,” declares Marc Benioff of , thebest-known proponent of the idea. But while SaaS is growing fast, it still represents only a tiny fraction of the overall software industry—a mere $3.35 billion last year, estimates Mr Maynard. Most observers expect it to be worth around $12 billion by 2010—but even that is equal only to Microsoft's quarterly sales today. There is no denying that SaaS is coming. But there is much debate, even among its advocates, about how quickly it will grow, and how widely it will be adopted.At the moment, small and medium-sized businesses are the most enthusiastic adopters of SaaS, since it is cheaper and simpler than maintaining rooms of server computers and employing staff to keep them running. Unlike the market for desktop software, which is dominated by Microsoft, or for high-end enterprise software, which is dominated by SAP and Oracle, the middle ground is still highly f ragmented, which presents an opportunity. “This is the last great software market left—the last unconsolidated market,” says Zach Nelson of NetSuite, which provides a suite of software services including accounting, sales-force automation and customer service. His firm is targeting small and medium-sized businesses by providing “verticalised” services—that is, versions of its software adapted to particular types of company, such as professional-service firms, wholesale distributors and software firms.Large companies, says Mr Nelson, have already made big investments in traditional software. “They've already been through the pain,” he says. So they will not be in a hurry to ditch their existing investments in traditional software from the likes of SAP and Or acle. “I have no fantasy of replacing those guys,” says Mr Nelson. But Mr Benioff of disagrees. His firm provides customer-relationship management (CRM) software as a service, which is already used by many big firms including Cisco, Sprint a nd Merrill Lynch. “The world's largest companies are now using for the world's largest CRM implementations,” he says. “It's the future of our industry that everything will be a service.”Even so, Mr Maynard reckons it will be some time before large companies fully embrace the service model. However,。
