• Most scientists and engineers find careers in three general sectors of society: colleges and universities, industries, and federal and stale agencies. Their work includes an array of activities, from the conduct of basic and applied research to the design and application of new commercial products to the operation and maintenance of large engineering systems.

  You can make your planning more effective by appreciating the direction in which professional careers are shifting within that larger picture.【66】But more than half the students who receive PhDs in science and engineering obtain work outside academe—a proportion that has increased steadily for 2 decades. And full-time academic positions in general are more difficult to find than they were during the 1960s and 1970s, when the research enterprise was expanding more rapidly. 【67】The end of the Cold War has removed some incentive for the federal government to fund defense-oriented basic research. Increased national and global competition has forced many industries to reduce expenses and staff. That means that there are fewer research and development positions in universities, industries, and government laboratories than there are qualified scientists and engineers looking for them. 【68】For example, there are strong public pressures for universities to shift their emphasis toward teaching and toward undergraduate education; the number of positions for permanent faculty has decreased; professors are no longer required to retire at a particular age; and more part-time and temporary faculty are being employed.【69】In engineering, careers are being transformed by several intersecting trends.【70】Companies value multilingual workers with a breadth of competencies—managerial as well as technical—and the ability to access and apply new scientific and technologic knowledge. The more flexible and mobile you can be, the more opportunities you will have and the greater will be your control over the shape of your career. A. Powerful changes have swept through the universities. B. All those trends 'affect the universities' ability to hire scientists and engineers. C. For example, increasing numbers of physicists, mathematicians, and engineers find their skills valued in the financial arena. D. International companies now draw employees from many nations, seeking out valued experts from a global pool of labor to work project by project. E. For example, for many students, a PhD will mean a career as an academic researcher. F. As our society changes, so too do the opportunities for careers in science and engineering. (66)
