The study examines selected roles of the information sector in the national economy. Among the findings are the following: (1) the information sector conducts relatively little international trade, in comparison to its domestic activity. Roughly 12% of U.S. exports are attributable to the information sector; over 97% of the sector's output is sold within the U.S.; and the sector's exports account for only a small fraction of 1% of GNP. (2) The historical pattern of employment shows that the portion of information workers has risen from 8% of the U.S. work force in 1870 to 41% in 1970. Relatively little of this growth is the result of new technological innovations such as telephones, radio, television and, more recently, computers. Rather, the growth of public and private bureaucracies, which now total 26% of our total work force, largely explains the growth of the sector. (3) Unemployment within the information sector has consistently been lower than in either the manufacturing or agricultural sectors of the national economy. (4) Since 1967, the high technology elements of the information sector, such as electronic components, computers and telecommunications equipment have experienced appreciably less price rise than has the economy as a whole. However, over the same time period, the service elements of the sector, including finance and insurance, education and medical care, have experienced greater rates of inflation than has the economy as a whole. 相似文献

Portfolio assessment has become a standard mechanism for the evaluation of prior learning for experienced students. The assessment of such learning in terms of the traditional liberal arts disciplines raises basic questions about the relationship of liberal learning to lived experience and about liberal learning outcomes. An informal survey of portfolio narratives receiving faculty approval for credit at various post-secondary institutions indicates a wide range of declarative, analytical, and interpretive assertions recognized as learning in these disciplines.I wish to thank the following institutions: Sinclair Community College, Clark University, the University of Alabama, and Indiana University who were kind enough to share materials on record while preserving the confidentiality through the removal of names, dates, etc. 相似文献
