Technological characteristics of the factory of the future will be influenced by both "science push" and "market pull". Science push relates to the many scientific developments that are being announced from laboratories around the world. ①The manufacturing community is alert to these developments and when creative people visualize opportunities to solve major problems with new scientific developments, they are responsive to initiate major project to attempt to capture a competitive edge. Market pull is the other dimension. The manufacturing community sees opportunities to gain a competitive edge by drawing existing or emerging technologies on to the shop floor, and they are willing to invest in the future. The driving force in both cases is the desire to increase productivity and quality. History has demonstrated that both phenomena are at work in the manufacturing environment. ②Underlying the future of the manufacturing environment of tomorrow are the strategic technologies that the we recognize today as playing an important role in our planning in industrial and university research laboratories. Let me elaborate on what I consider the strategic technologies in the laboratory with both medium and long-range perspectives on the future. My strategic technologies include: new materials (including polymers, alloys, ceramics and composites, and superconductors ), computer engineering, microelectronics, micro-fabrication, photonics, and manufacturing system (automation for machines and processes, new processes, engineering management). The reality of the impact of the strategic technologies which I have mentioned is not an issue. What are the issues include: how rapidly will their impact be left, how will the capital investments required be justified, and how will we educate the workforce to implement and manage them. I believe these issues will be resolved in an evolutionary way rather than as a new industrial revolution. There are already unfortunate examples of failure in attempts to implement individual views of factories of the future. ③The underlying problems will surface when we attempt too much, too soon, and without a thorough knowledge of all of the important features of strategic technologies and of whether they are fit for an effective manufacturing facility: The lack of standards has been recognized as a major deterrent to integration, and major steps have been taken on a national and worldwide basis to correct the situation. We cannot overestimate the power of the human being to adapt and to succeed. We have not yet duplicated this power with the computer. However, we have achieved the ability to use the computer to make the human more productive, more reliable and more powerful. This is perhaps the beginning for developing a more focused view of what we mean by the factory of the future. The issue of strategic technologies is of great importance to the development of the factory of the future. It is a matter of survival. The word "deterrent" (Line 10, Par
A. 4) most probably refers to ______.A. advantageB. shortcomingC. disadvantageD. handicap
For one thing, tightness in the job market seems to have given men an additional incentive to take jobs where they can find them. Although female dominated office and service jobs for the most part, rank lower in pay and status, "they’re still there," says June O’Neill, director of program and policy research at the institute. Traditionally mate blue-collar jobs, meanwhile, "aren’t increasing at all". At the same time, she says, "The outlooks of young people are different." Younger men with less rigid views on what constitutes male or female work "may not feel there’s such a stigma to work in a female dominated field." Although views have softened, men who cross the sexual segregation line in the job market may still face discrimination and ridicule. David Anderson, a 36-year-old former high school teacher, says he found secretarial work "a way out of teaching and into the business world". He had applied for work at 23 employment agencies for "management training jobs that didn’t exist", and he discovered that "the best skill ! had was being able to type 70 words a minute". He took a job as a secretary to the marketing director of a New York publishing company. But he says he could feel a lot of people wondering what he was doing there and if something was wrong with him. Mr. Anderson’s boss was a woman. When she asked him to fetch coffee, he says, "The other secretaries’ eyebrows went up." Sales executives who came in to see his boss, he says, "couldn’t quite believe that I could and would type, take dictation, and answer the phones." Males sometimes find themselves mistaken for higher status professionals. Anthony Shee, a flight attendant with U.S. Air Inc., has been mistaken for a pilot. Mr. Anderson, the secretary, says he found himself being "treated in executive tones whenever I wore a suit". In fact, the men in traditional female jobs often move up the ladder fast. Mr. Anderson actually worked only seven months as a secretary. Then he got a higher level, better paying job as a placement counselor at an employment agency. "I got a lot of encouragement to advance," he says, "including job tips from male executives who couldn’t quite see me staying a secretary." Experts say, for example that while men make up only a small fraction of elementary school teachers, a disproportionate number of elementary principals are men. Barbara Bergmann, an economist at the University of Maryland who has studied sex segregation at work, believes that’s partly because of "sexism in the occupational structure" and partly because men have been raised to assert themselves and to assume responsibility. Men may also feel more compelled than women to advance, she suspects. Why was Anthony Shee, a flight attendant with U.S. Air Inc., mistaken for a pilot
A. Because he always wore a pilot’s uniform.
Because he told people he was a pilot instead of a flight attendant.
C. Because he wants to be a pilot.
D. Because people tend to mistake men for higher status professionals.
