单选题The statistics I've cited and the living examples are all too familiar to you. But what may not be so familiar will be the increasing number of women who are looking actively for advancement of for a new job in your offices. This woman may be equipped with professional skills and perhaps valuable experience, she will not be content to be Executive Assistant to Mr. Seldom Seen of the Assistant Vice President's Girl Friday, who is the only one who comes in on Saturday. She is the symbol of what I call the Second Wave of Feminism. She is the modern woman who is determined to be. Her forerunner was the radical feminist who interpreted her trapped position as a female as oppression by the master class of men. Men, she believed, had created a domestic, servile role for women in order that men could have the career and the opportunity to participate in making the great decisions of society. Thus the radical feminist held that women through history had been oppressed and dehumanized, mainly because man chose to exploit his wife and the mother of his children. Sometimes it was deliberate exploitation and sometimes it was the innocence of never looking beneath the pretensions of life. The radical feminists found strength in banding together. Coming to recognize each other for the first time, they could explore their own identities, realize their own power, and view the male and his system as the common enemy. The first phases of feminism in the last five years often took on this militant, class-warfare tone. Betty Friedan, Gloria Steinem, Germaine Greer, and many others hammered home their ideas with a persistence that aroused and intrigued many of the brightest and most able women in the country. Consciousness-raising groups allowed women to explore both their identities and their dreams — and the two were often found in direct conflict. What is the stereotyped role of American women? Marriage. A son. Two daughters. Breakfast. Ironing. Lunch. Bowling, maybe a garden club of for the very daring, non-credit courses in ceramics. Perhaps an occasional cocktail party. Dinner. Football or baseball on TV. Each day the same. Never any growth in expectations — unless it is growth because the husband has succeeded. The inevitable question: "Is that all there is to life?" The rapid growth of many feminist organizations attests to the fact that these radical feminists had touched some vital nerves. The magazine "Ms. " was born in the year of the death of the magazine "Life. " But too often the consciousness-raising sessions became ends in themselves. Too often sexism reversed itself and man-hating was encouraged. Many had been with the male chauvinist. It is not difficult, therefore, to detect a trend toward moderation. Consciousness-raising increasingly is regarded as a means to independence and fulfillment, rather than a ceremony of fulfillment itself. Genuine independence can be realized through competence, through finding a career, through the use of education. Remember that for many decades the education of women was not supposed to be useful.

单选题Industrial production managers coordinate the resources and activities required to produce millions of goods every year in the United States. Although their duties vary from plant to plant, industrial production managers share many of the same major responsibilities. These responsibilities include production scheduling, staffing, procurement and maintenance of equipment, quality control, inventory control, and the coordination of production activities with those of other departments. The primary mission of industrial production managers is planning the production schedule within budgetary limitations and time constraints. They do this by analyzing the plant's personnel and capital resources to select the best way of meeting the production quota. Industrial production managers determine, often using mathematical formulas, which machines will be used, whether new machines need to be purchased, whether overtime or extra shifts are necessary, and what the sequence of production will be. They monitor the production run to make sure that it stays on schedule and correct any problems that may arise. Industrial production managers also must monitor product standards. When quality drops below the established standard, they must determine why standards are not being maintained and how to improve the product. If the problem relates to the quality of work performed in the plant, the manager may implement better training programs, reorganize the manufacturing process, or institute employee suggestion or involvement programs. If the cause is substandard materials, the manager works with the purchasing department to improve the quality of the product's components. Because the work of many departments is interrelated, managers work closely with heads of other departments such as sales, procurement, and logistics to plan and implement company goals, policies, and procedures. For example, the production manager works with the procurement department to ensure that plant inventories are maintained at their optimal level. This is vital to a firm's operation because maintaining the inventory of materials necessary for production ties up the firm's financial resources, yet insufficient quantities cause delays in production. A breakdown in communications between the production manager and the purchasing department can cause slowdown and a failure to meet production schedules. Just-in-time production techniques have reduced inventory levels, making constant communication among the manager, suppliers, and purchasing departments even more important. Computers play an integral part in this coordination. They also are used to provide up-to-date information on inventory, the status of work in progress, and quality standards. Production managers usually report to the plant manager or the vice president for manufacturing, and may act as liaison between executives and first line supervisors. In many plants, one production manager is responsible for all aspects of production. In large plants with several operations, there are managers in charge of each operation, such as machining, assembly, or finishing.

单选题The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, but this is largely because, 1 animals, we stand upright. This means that our noses are 2 to perceiving those smells which float through the air, missing the majority of smells which stick to surfaces. In fact, though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of 3 human smells even when these are 4 to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, whereas others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate 5 smell receptors in the nose. These receptors are the cells which sense smells and send 6 to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when 7 to it often enough. The explanation for insensitivity to smell seems to be that brain finds it inefficient to keep all smell receptors working all the time but can 8 new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not 9 of the usual smell of our own house but we notice new smells when we visit someone else"s. The brain finds it best to keep smell receptors 10 for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.

单选题 In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, the era of digital convergence goes better than yesterday's celebrated "information superhighway". Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each other. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media. The problems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable. Even once global standards are assured, however, a further obstacle lies in wait. The Internet is plagued by long, erratic response times because it is a pull-technology, driven by patterns of user demands. Push technology, on the other hand, reverses the relationship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom. Besides the issue of consumer habits, infrastructure costs are set to be immense, and will have to be met by national states or the private sector before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coerced through clever marketing to upgrade to newer phones with more features to reinforce their dependence. Whatever the outcome, it is obvious that technology will play an increasing part in our everyday lives. Beyond technology, digital convergence embraces the services, industrial practices and social behavior that form modern society. We have in our hands the technology to construct the most sophisticated machines ever built, but if they are unusable, simply because of their operating instructions, then recent lessons have taught us they will not survive. Whatever we design must be simple, reliable and useful. Perhaps this is where artificial intelligence will come in.

单选题Ironically, the intellectual tools currently being used by the political right to such harmful effect originated on the academic left. In the 1960s and 1970s a philosophical movement called postmodernism developed among humanities professors (26) being deposed by science, which they regarded as right-leaning. Postmodernism (27) ideas from cultural anthropology and relativity theory to argue that truth is (28) and subject to the assumptions and prejudices of the observer. Science is just one of many ways of knowing, they argued, neither more nor less (29) than others, like those of Aborigines, Native Americans or women. (30) , they defined science as the way of knowing among Western white men and a tool of cultural (31) . This argument (32) with many feminists and civil-rights activists and became widely adopted, leading to the "political correctness" justifiably (33) by Rush Limbaugh and the "mental masturbation" lampooned by Woody Allen. Acceptance of this relativistic worldview (34) democracy and leads not to tolerance but to authoritarianism. John Locke, one of Jefferson's "trinity of three greatest men," showed (35) almost three centuries ago. Locke watched the arguing factions of Protestantism, each claiming to be the one true religion, and asked. How do we know something to be true? What is the basis of knowledge? In 1689 he (36) what knowledge is and how it is grounded in observations of the physical world in An Essay Concerning Human Understanding. Any claim that fails this test is "but faith, or opinion, but not knowledge. " It was this idea—that the world is knowable and that objective, empirical knowledge is the most (37) basis for public policy that stood as Jefferson's foundational argument for democracy. By falsely (38) knowledge with opinion, postmodernists and antiscience conservatives alike collapse our thinking back to a pre-Enlightenment era, leaving no common basis for public policy. Public discourse is (39) to endless warring opinions, none seen as more valid than another. Policy is determined by the loudest voices, reducing us to a world in which might (40) right—the classic definition of authoritarianism.
