单选题Today, a high-level finance manager is just as likely to be a casual-looking 21-year-old as a balding executive. They have all either started their own companies or head a division within an existing firm. Most are under 30. Many of them share a tendency to think, speak and act fast. A detailed psychological study carried out recently on young business start-uppers aged over 25 revealed some common characteristics. The head psychologist at the University of Northumbria, Dr. Martyn Dyer-Smith, says "We found that they are opportunists. They have that entrepreneurial ability to take whatever is in front of them and turn it to their advantage. Any fool can make US $ 2 if they are in the right place at the right time, what is much harder is to actually plan their business. Originally I had a hypothesis that they planned a long time ahead, but I was wrong. What came across was a surprisingly short planning time. They took the opportunities as and when they came up." What cannot be underestimated, though, is self-confidence. "There is an amazing, almost abnormal, belief in themselves and (they) go very much on intuition." Says Dyer-Smith. While there is no typical pattern to what puts someone in the fast lane, there are some common threads: living up to the expectations of parents, channeling excessive amounts of energy into business, or finding a way to overcome personal barriers such as dyslexia (a reading disability) or learning difficulties, for example. The biggest surprise was the lack of young women. This was particularly unexpected, given the recent publicity about how girls are performing better than boys at school and becoming more confident and ambitious. But young women are opting for more secure careers rather than gambling with their future. With only a handful of female role models, some girls are not even considering being their own boss, let alone working on a concept fresh out of school, according to Dr Susan Vinnicombe, director of the center for the Development of Women Business Leader. "Women are going more into the corporate structure and doing well there. But perhaps the reason that they are not doing business for themselves at an earlier age is because women"s attitudes are different. They perceive risk in a different way to men, who are not worried about borrowing huge amounts of money if it"s going to help their business in the long term. Women are more cautious and more hesitant ," she says. Vinnicombe sees the lack of female entrepreneurs as part of a larger problem about women and the IT industry. Given that the computer world is one of the key areas for growth, where youth is an asset, it is "remarkable" that so many women are missing out on it. "The number of women in IT has actually dropped in the past 10 years. There is a real problem with attracting them to the IT industry, as girls don"t seem to want to do it at university. It"s become such a worrying issue that I know the government is looking into ways to attract them."

单选题Protection of the environment is based on a principle that is beginning to be used in the field of jurisprudence. The principle has to do with property rights. The idea is that we all have a property right in the air and water around us. If a business firm pollutes that air or water, their act in so doing constitutes damage to something we own—just as if the firm had dropped a smoke bomb down our chimney. Our legal ease against such a firm is then baaed on the complaint that we deserve compensation for an infringement of our right to use our private property as we please ( provided we don' t interfere with the same rights of a neighbor). Assuming we win the case, the offending firm then has to pay us for damaging our property—the air or water we "own". And so protection of the environment, specifically the control of pollution, now rests on the idea that we, as members of the public, share a right to clean air and water and to the good health that clean air and water quality can give us. But, as always, costs and benefits are involved in any decision to improve the environment. In an Adam Smithian, self-interested world, entrepreneurs or businessmen are expected to increase their profits as much as possible. The natural way to do this is to produce at the lowest possible cost. But at whose cost? It is obviously cheaper for entrepreneurs to dump waste into the nearest stream or into the atmosphere than to truck it to some waste disposal facility or to filter it as it comes out of smokestacks. Therefore, what may be sensible for entrepreneurs may not be desirable for the community. Here is a classic trade-off: When the government intervenes to force entrepreneurs to stop polluting, entrepreneurs have to adopt more expensive means of production or waste disposal. Inevitably, they will charge higher prices, and, given no change in demand, the quantity demanded will drop and workers will be laid off. The trade-off is therefore cleaner air and water or more unemployment. This is how economists view this problem.
