单选题Over the past decade, American companies have tried hard to find ways to discourage senior managers from feathering their own nests at the expense of their shareholders. The three most popular reforms have been recruiting more outside directors in order to make boards more independent, linking bosses' pay to various performance measures, and giving bosses share options, so that they have the same long-term interests as their shareholders. These reforms have been widely adopted by America's larger companies, and surveys suggest that many more companies are thinking of following their lead. But have they done any good? Three papers presented at the annual meeting of the Academy of Management in Boston this week suggest not. Start with those independent boards. On the face of it, dismissing the boss's friends from the board and replacing them with outsiders looks a perfect way to make senior managers more accountable. But that is not the conclusion of a study by Professor James Westphal. Instead, he found that bosses with a boardroom full of outsiders spend much of their time building alliances, doing personal favors and generally pleasing the outsiders. All too often, these seductions succeed. Mr. Westphal found that, to a remarkable degree, "independent" boards pursue strategies that are likely to favor senior managers rather than shareholders. Such companies diversify their business, increase the pay of executives and weaken the link between pay and performance. To assess the impact of performance-related pay, Mr. Westphal asked the bosses of 103 companies with sales of over $1 billion what measurements were used to determine their pay. The measurements varied widely, ranging from sales to earnings per share. But the researcher's big discovery was that bosses attend to measures that affect their own incomes and ignore or play down other factors that affect a company's overall success. In short, bosses are quick to turn every imaginable system of corporate government to their advantage--which is probably why they are the people who are put in charge of things. Here is a paradox for the management theorists: any boss who cannot beat a system designed to keep him under control is probably not worth having.

单选题Many American colleges permit foreign students to live in college housing or housing not owned by the university, such as an apartment. College housing is usually in a dormitory, or dorm for short. Many foreign students say that the dorms are less costly than apartments. They say dorms offer quiet study areas and areas for social activities or sports. They say dorms are close to places they go every day, like the library, computer center and classrooms. They also say that living in the room provides the best chance to get to know other students. Dormitories may have as few as twelve students or as many as one thousand. Some dorms are organized into areas called suites. Suites have several bedrooms, a large, living area and a bathroom. Six or more people may live in one suite. Other dorms have many rooms along a hallway. Two students usually live in each room. On each floor there is a large bathroom for all the students who live on that floor. Sometimes there is also a kitchen for preparing food. In most universities, males and females live in the same dorm. They may even live on the same floor. But they usually may not live in the same room or suite. Most universities have some dorms for men and women.

单选题Discoveries in science and technology are thought by "untaught minds" to come in blinding flashes or as the result of dramatic accidents. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. He experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error. Innovation is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score. The point is that the players who score most are the ones who take the most shots at the goal — and so it goes with innovation in any field of activity. The prime difference between innovators and others is one of approach. Everybody gets ideas, but innovators work consciously on theirs, and they follow them through until they prove practicable or otherwise. What ordinary people see as fanciful abstractions, professional innovators see as solid possibilities. "Creative thinking may mean simply the realization that there's no particular virtue in doing things the way they have always been done," wrote Rudolph Flesch, a language authority. This accounts for our reaction to seemingly simple innovations like plastic garbage bags and suitcases on wheels that make life more convenient: "How come nobody thought of that before?" The creative approach begins with the proposition that nothing is as it appears. Innovators will not accept that there is only one way to do anything. Faced with getting from A to B, the average person will automatically set out on the best-known and apparently simplest route. The innovator will search for alternate courses, which may prove easier in the long run and are bound to be more interesting and challenging even if they lead to dead ends. Highly creative individuals really do march to a different drummer.
