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. The subject under discussion in the passage is about______.

In 1798 the political economist Malthus predicted that in time mankind would face starvation, having outgrown the available food supplies. Today, a century and a half later, there are still experts who forecast the same global disaster unless urgent measures are taken to prevent it. By the end of the present century there may well be over five thousand million people living on this globe, ail increase of over fifty per cent of today’s figure. In order to keep pace with this increase in mankind the farmers of the world would have to step up their production of food by at least two per cent every year. Such a rate of increase has never been maintained in any country by conventional methods of agriculture, despite modern mechanization and the widespread use of fertilizers. There are no large worthwhile reserves of potential farmland, remaining, and good fertile land is continually being diverted to industrial use. Moreover, erosion of the soil takes a constant toll. Intensive research, carried out over many years in all manner of climatic conditions, has produced a revolutionary method of growing crops without using any soil at all. Hydroponics, as this technique is called, may well be the answer to all our food worries. Already it has accomplished wonders in producing huge crops. Hydroponics was once a complicated and expensive business; now it is well out of the experimental stage. Labor costs are far lower than when normal methods of agriculture are employed. In fact, it is a completely automatic system. There is no hard manual work, no digging or plowing, and no weeding to speak of. Yields can be far higher than they are in soil. Judging from the passage, the most important advantage of hydroponics should be______.
When I decided to quit my full time employment it never occurred to me that I might become a part of a new international trend.A lateral movethat hurt my pride and blocked my professional progress prompted me to abandon my relatively high profile career although, in the manner of a disgraced government minister, I covered my exit by claiming "I wanted to spend more time with my family". Curiously, some two-and-a-half years and two novels later, my experiment in what the Americans term "downshifting" has turned my tired excuse into an absolute reality, I have been transformed from a passionate advocate of the philosophy of "having it all" preached by Linda Kelsey for the past seven years in the page of She magazine, into a woman who is happy to settle for a bit of everything. I have discovered, as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build up of stress, that abandoning the doctrine of "juggling your life" and making the alternative move into "downshifting" brings with it far greater rewards than financial success and social status. Nothing could persuade me to return to the kind of life Kelsey used to advocate and I once enjoyed: 12 hour working days, pressured deadlines, the fearful strain of office politics and the limitations of being a parent on "duality time". In America, the move away from juggling to a simpler, less materialistic lifestyle is a well-established trend. Downshifting — also known in America as "voluntary simplicity" — has, ironically, even bred a new area of what might be termed anticonsumerism. There are a number of best-selling downshifting self-help books for people who want to simplify their lives. There are newsletters, such as The Tightwad Gazette, that give hundreds of thousands of Americans useful tips on anything from recycling their ding-film to making their own soap. There are even support groups for those who want to achieve the mid-1990s equivalent of dropping out. While in America the trend started as a reaction to the economic decline — after the mass redundancies caused by downsizing in the late-1980s—and is still linked to the politics of thrift, in Britain, at least among the middle-class down-shifters of my acquaintance, we have different reasons for seeking to simplify our lives. For the women of my generation who were urged to keep juggling through the 1980s, downshifting in the mid-1990s is not so much a search for the mythical good life — growing your own organic vegetables, and risking turning into one — as a personal recognition of your limitations. The writer quit her full-time job because______.
