单选题A close analogy to study design is the rough sketch made by an artist before he commits his vision to canvas. The broad outlines are drawn, the proper perspective achieved, and the total impact of the picture-to-be can be partially appreciated in advance. So it is with the design of research; it specifies in advance the kinds of statements that can be made on the basis of its findings and fix the perspectives against which these findings are to be evaluated. One major purpose of this study was to demonstrate whether or not the newer social research techniques could help in broadening and deepening knowledge concerning juvenile delinquency. Construction of the design was guided by this goal of exploring new methods in the analysis of juvenile delinquency. However, research technique developed in one content cannot be mechanically transferred to another. A new application of a research technique requires substantial changes and it is these innovative modifications that this study offers as its contribution. Juvenile delinquency has been the subject of many previous studies using a variety of research techniques. This study makes an additional contribution by using a design specially planned to permit a comparison of several approaches. The drawing up of the study design profited greatly from an extensive survey of previous researches on crime, undertaken during the earliest stage of the project. It was found that most studies could be classified as belonging study and personal motivation study. Each type has its characteristic design and mode of interpretation and each has produced information of considerable importance. Yet no attempt was made in any of the studies to integrate one or more of these three design types. It became apparent that one of the major contributions a pilot study could make to both method and substantive findings would be to bring all three study types together in one design for the purpose of correlating their findings and evaluating their relative importance in producing data of use to the practitioner.

单选题The miserable fate of Enron's employees will be a landmark in business history, one of those awful events that everyone agrees must never be allowed to happen again. This urge is understandable and noble: thousands have lost virtually all their retirement savings with the demise of Enron stock. But making sure it never happens again may not be possible, because the sudden impoverishment of those Enron workers represents something even larger than it seems. It's the latest turn in the unwinding of one of the most audacious promise of the 20th century. The promise was assured economic security — even comfort essentially everyone in the developed world. With the explosion of wealth, that began in the 19th century it became possible to think about a possibility no one had dared to dream before. The fear at the center of daily living since caveman days-lack of food warmth, shelter — would at last lose its power to terrify. That remarkable promise became reality in many ways. Governments created welfare systems for anyone in need and separate programs for the elderly(Social Security in the U. S.). Labor unions promised not only better pay for workers but also pensions for retirees. Giant corporations came into being and offered the possibility — in some cases the promise — of lifetime employment plus guaranteed pensions. The cumulative effect was a fundamental change in how millions of people approached life itself, a reversal of attitude that most rank as one of the largest in human history. For millennia the average person's stance toward providing for himself had been. Ultimately I'm on my own. Now it became, ultimately I'll be taken care of. The early hints that this promise might be broken on a large scale came in the 1980s. U. S business had become uncompetitive, globally and began restructuring massively, with huge layoffs. The trend accelerated in the 1990s as the bastions of corporate welfare faced reality. IBM ended its no-layoff policy. AT&T fired thousands, many of whom found such a thing simply incomprehensible, and a few of whom killed themselves. The other supposed guarantors of our economic security were also in decline. Labor-union membership and power fell to their lowest levels in decades. President Clinton signed a historic bill scaling back welfare. Americans realized that Social Security won't provide social security for any of us. A less visible but equally significant trend a affected pensions. To make costs easier to control, companies moved away from defined benefit pension plans, which obligate them to pay out specified amounts years in the future, to define contribution plans, which specify only how much goes into the play today. The most common type of defined-contribution plan is the 401(k). the significance of the 401(k)is that it puts most of the responsibility for a person's economic fate back on the employee. Within limits the employee must decide how much goes into the plan each year and how it gets invested — the two factors that will determine how much it's worth when the employee retires. Which brings us back to Enron? Those billions of dollars in vaporized retirement savings went in employees' 401(k)accounts. That is, the employees chose how much money to put into those accounts arid then chose how to invest it. Enron matched a certain proportion of each employee's 401(k)contribution with company stock, so everyone was going to end up with some Enron in his or her portfolio, but that could be regarded as a freebie, since nothing compels a company to match employee contributions at all. At least two special features complicate the Enron case. First, same shareholders charge top management with illegally covering up the company's problems, prompting investors to hang on when they should have sold. Second, Enron's 401(k)accounts were lacked while the company changed plan administrators in October, when the stock was failing, so employees could not have closed their accounts if they wanted to. But by far the largest cause of this human tragedy is that thousands of employees were heavily overweighed in Enron stock. Many had placed 100% of their 401(k)assets in the stock rather than in the 18 other investment options they were offered. Of course that wasn't prudent, but it's what some of them did. The Enron employees" retirement disaster is part of the larger trend away from guaranteed economic security. That's why preventing such a thing from ever happening again may be impossible. The huge attitudinal shift to I'll-be-taken-care-of took at least a generation. The shift back may take just as long. It won't be complete until a new generation of employees see assured economic comfort as a 20th-century quirk, and understand not just intellectually but in their bones that, like most people in most times and places, they're on their own.

单选题According to Paragraph 2, which of the following statements is NOT true?

单选题He built a hut on a piece of rough land near a rock fall. In the wet season there was a plentiful stream, and ever the years he encouraged the dry forest to surround him with a thick screen. The greener it became the easier it was to forget the outside. In time Melio (not without some terrible mistakes) learnt how to live in spite of the difficulties up on that mountain shelf. His only neighbors were a family group of Parakana Indians who, for reasons known only to themselves, took a liking to Melio. Their Chief never looked closely at Melio and said to himself that this white man was as mad as a snake which chews off its own tail. The Parkanas taught Melio to catch fish with the help of a wild plant which made them senseless in the stream. It gave off a powerful drug when shaken violently through the water. They showed him how to hunt by laying traps and digging. In time Melio's piece of land became a regular farm. He had wild birds, fat long-legged ones and thin nearly featherless chickens, and his corn and salted fish was enough to keep him stocked up through the wet season. The Parakanas were always around him. He'd never admit it but he could feel that the trees were like the bars of a prison: they were watching him. It was as if he was there by courtesy of the Chief. When they came to him, the Indians never entered his house with its steeply sloping roof of dried grass and leaves. They had a delicate way of behaving. They showed themselves by standing in the shade of the trees at the clearing's edge. He was expected to cross the chicken strip towards them. Then they had a curious but charming habit of taking a pace back from him, just one odd step backwards into their green corridors. Melio never could persuade them to come any closer. The group guessed at Melio's hatred for his civilized brothers in the towns far away. They knew Melio would never invite any more white men up here. This pleased the Parakanas. It meant that traders looking for rubber and jewels would never reach them. Their Melio would see to that. They were safe with this man and his hatred.

单选题 It happened in the late fall of 1939 when, after a Nazi submarine had penetrated the British sea defense around the Firth of Forth and damaged a British cruiser, Reston and a colleague contrived to get the news past British censorship. They cabled a series of seemingly harmless sentences to The Times's editors in New York, having first sent a message instructing the editors to regard only the last word of each sentence. Thus they were able to convey enough words to spell out the story. The fact that the news of the submarine attack was printed in New York before it had appeared in the British press sparked a big controversy that led to an investigation by Scotland Yard and British Military Intelligence. But it took the investigators eight weeks to decipher The Times's reporters' code, an embarrassingly slow bit of detective work, and when it was finally solved the incident had given the story very prominent play, later expressed dismay that the reporters had risked so much for so little. And the incident left Reston deeply distressed. It was so out of character for him to have. become involved in such a thing. The tactics were questionable and, though the United States was not yet in the war, Britain was already established as America's close ally and breaking British censorship seemed both an irresponsible and unpatriotic thing to do.

单选题Writers nowadays who value their reputation among the more sophisticated hardly dare to mention progress without including the word in quotation marks. The implicit confidence in the beneficence of progress that during the last two centuries marked the advanced thinker has come to be regarded as the sign of a shallow mind. Though the great mass of the people in most parts of the world still rest their hopes on continued progress, it is common among intellectuals to question whether there is such a thing, or at least whether progress is desirable. Up to a point, this reaction against the exuberant and naive belief in the inevitability of progress was necessary. So much of what has been written and talked about it has been indefensible that one may well think twice before using the word. There never was much justification for the assertion that "civilization has moved, is moving, and will move in a desirable direction", nor was there any ground for regarding all changes as necessary or progress as certain and always beneficial. Least of all was there warrant for speaking about recognizable "laws of progress" that enable us to predict the conditions toward which we were necessarily moving, or for treating every foolish thing men have done as necessary and therefore right. But if the fashionable disillusionment about progress is not difficult to explain, it is not without danger. In one sense, civilization is progress and progress is civilization. The preservation of the kind of civilization that we know depends on the operation of forces which, under favorable conditions, produce progress. If it is true that evolution does not always lead to better things, it is also true that, without the forces which produce it, civilization and all we value—indeed, almost all that distinguishes man from beast—would neither exist nor could long be maintained. The history of civilization is the account of a progress which, in short space of less than eight thousand years, has created nearly all we regard as characteristic of human life. After abandoning hunting life, most of our direct ancestors, at the beginning of Neolithic culture, took to agriculture and soon to urban life perhaps less than three thousand years or one hundred generations ago. It is not surprising that in some respects man's biological equipment has not kept pace with that rapid change, that the adaptation of his non-rational part has lagged somewhat, and that many of his instincts and emotions are still more adapted to the life of a hunter than to life in civilization. If many features of our civilization seem to us unnatural, artificial, or unhealthy, this must have been man's experience ever since he first took to town life, which is virtually since civilization began. All the familiar complaints against industrialism, capitalism, or over-refinement are largely protest against the new way of life that man took up a short while ago after more than half a million years' existence as a wandering hunter, and that created problems still unsolved by him. When we speak of progress in connection with our individual endeavors or any organized human effort, we mean an advance toward a known goal. It is not in this sense that social evolution can be called progress, for it is not achieved by human reason striving by known means toward a fixed aim. It would be more correct to think of progress as a process of formation and modification of the human intellect, a process of adaptation and learning in which not only the possibilities known to us but also our values and desires continually change. Its consequences must be unpredictable, it always leads into the unknown, and the most we can expect is to gain an understanding of the kind of forces that bring it about. Yet, though such a general understanding of the character of this process of cumulative growth is indispensable if we are to try to create conditions favorable to it, it can never be knowledge which will enable us to make specific predictions. The claim that we can derive from such insight necessary laws of evolution that we must follow is an absurdity. Human reason can neither predict nor deliberately shape its own future. Its advances consist in finding out where it has been wrong.
