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

This study explores whether a synthesis of clinical and statistical data taken from the psychoeducational reports completed on a group of 42, 9- to 11-year-old boys referred to a Child Psychiatric Outpatient Department for school-learning problems, would yield discrete clinical categories or clusters of children. An amalgamated hierarchical clustering technique which formed clusters by subjects based on a measure of euclidean distance was used. Forty-two reports were evaluated by licensed educational psychologists in five input areas: Developmental History, School History, Cognitive Functioning, Sensorimotor/Perceptual Functioning, and Academic Achievement. One of three educational placement recommendations was identified for each subject: No Educational Placement Intervention Necessary, Special Tutoring or Remediation, and Special Class Placement. Using clinical characteristic ratings given by the evaluators on each variable, a similarity-dissimilarity matrix was formed which classified subjects into four discrete clusters based on their clinical profiles. A χ2 test determined that there was a significant association (p < .01) between cluster membership and educational placement recommendations. 相似文献

The present study seeks to identify factors among university students that may be associated with homophobic attitudes and whether homophobia may be reduced by educational interventions, such as knowledge-based curricula found in college sexuality courses. Participants were 128 undergraduate students attending a small, private university in the northwestern region of the United States. At the beginning and end of the fall semester 2004, survey packets consisting of a demographic questionnaire, the Sexual Opinion Survey, the Homophobia Scale, a sexual knowledge survey, and the Bem Sex Role Inventory were administered to students attending a human sexuality class and a comparison group of students enrolled in professional and social science introductory courses. Relative to the comparison group, homophobia levels significantly decreased over the course of the semester among students attending the sexuality class. The effect of attending the class on reducing homophobia was partially mediated by an increase in self-reported knowledge about sexual matters. Taken together, these results suggest that the knowledge-based curriculum of sexuality courses may play an important role in affecting broader attitudes about sexuality among college students, including attitudes about homosexuality. 相似文献

This qualitative study applied methods used in discourse analysis to investigate how a consultant's questioning supported the goal of group consultation to empower beginning teachers to become effective problem solvers in their work environment. The focus of the study was on the process of questioning and communicative coherency as the group evolved over the course of the school year. The participants in this study were 7 White elementary school teachers in their first year of teaching. There were 12 sessions held over an 8-month period. The investigators found evidence of a parallel process between the coordinate consultation process and coherency in consultative discourse, such that as the coordinate process developed and improved, so did the coherency of group discourse. Implications for practice, training, and future research are discussed. 相似文献
