Proceedings of the 1971 Career Seminar for M.I.T. Alumni are presented in this volume for the purpose of providing information about changes in career orientation in the engineering, scientific, and managerial fields. The material is given in the style of discussions between speakers and audience. The headings are: Opening Remarks; The Effect of Changing Federal Spending on Employment Opportunities; Forecast of Overall Needs in the Coming Decade; Changing Careers in Electronics, Aerospace, and Reprography; Career Opportunities in Computers and Information Processing; Career Opportunities in the Medical Fields; Career Opportunities in Ocean Engineering and Electric Power Engineering; Career Opportunities in Finance, Consumer Goods, and Housing; and Changing Careers. Emphases are placed on long-range personal career planning and training rather than on immediate job placement. Personal adjustment problems of shifting careers are also dealt with. The volume indicates that new opportunities appear for engineers and scientists in such fields as environmental protection, urban affairs, housing, education, health care, and ocean engineering. Included are illustrations of recent employment trends and a list of invited speakers. (CC)
