A major investment in educational television programmes by the federal government led the United States Department of Education to seek ways to extend the audience size for these programmes beyond public television by placing them on commercial broadcast stations in America. This article describes the programmes, the marketing organization and strategies used to promote programming to the commercial marketplace, and the successes achieved in persuading commercial broadcasters to accept educational children's programming, particularly programmes aimed at minority audiences.  相似文献

The aim of this study is to elicit from staff members and from postgraduate students their personal constructs of research effectiveness. Based on Kelly's Personal Construct Theory, the repertory grid technique was used to elicit, analyse, discuss, and negotiate individual and group constructs of research with the result of arriving at a greater group consensus and a clearer picture of shared criteria for research effectiveness.  相似文献

This study examines the influence of the opportunity costs of school attendance, educational quality attributes, and household socioeconomic status on the educational demand of Mexican Americans, African Americans, and non-Hispanic whites using the 1988–1990 surveys of the National Education Longitudinal Study. Implementing a utility-maximizing framework, educational demand assumes the form of schools' average daily attendance rates and student dropout decisions between the 8th and 10th grades. The basic results suggest that a school's attendance rate is sensitive to educational quality and student characteristics. Moreover, the demand for education measured by student attrition inversely relates to unexplained school attendance, and is positively affected by household socioeconomic status. Some policy recommendations based on the results are discussed.  相似文献

Kindergarten, third-grade, and sixth-grade children were told 2 stories about a group of children who made artwork that was subsequently sold at a craft fair. The characters in one story were described as friends, while the characters in the other story were described as strangers (relationship condition). 1 character in each story was presented as the oldest in the group, 1 as the most productive, and 1 as the poorest. Children were asked to allocate 9 dollars to the 3 characters under each relationship condition, provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children allocated more money to needy friends than to needy strangers and more to productive strangers than to productive friends. Kindergartners' allocations and fairness ratings did not vary with relationship. Rationales for allocation judgements suggested that equality was the most salient principle for decisions at all ages, but the older children provided rationales based on benevolence more often than younger children when characters were presented as friends.  相似文献

The present study aims at assessing faculty attitudes toward institutional competitive strategies in U.S. research universities and at exploring some of the correlates of these attitudes.

A stratified random sample of 40 U.S. research university departments, 10 each in physics, sociology, electrical engineering, and education was surveyed by means of a questionnaire.

The major findings of this study suggest that faculty members at research universities express non‐receptive attitudes toward university generic strategies, although, more productive,more satisfied and more committed faculty members are relatively more receptive toward university strategies than less productive, less satisfied and less committed faculty members.

The meaning and the implications of these findings are discussed.  相似文献
