Abstract

An empirical examination of accredited American higher education institutions was conducted to obtain baseline data regarding distance education copyright, intellectual property, and antitrust concerns. Additionally, a multiple‐case study involving ten of the top thirty accredited distance education institutions in America was conducted. Policy approaches were examined for all institutions, and differences were discussed between public and private institutions as well as between the following Carnegie Classification institutions: Research I and II, Doctorate I and II, and Master's I and II. Data indicated that, out of the schools surveyed, 22% of the institutions in these Carnegie Classification categories published copyright and intellectual property policies on their institution's Web site. In the case study, it was found that 90% of the institutions centrally controlled their distance education program administration as well as the copyright and intellectual property policies related to it.  相似文献

The Older Americans Act and its network of state and area agencies are dynamic mechanisms for human services. The “aging network” has entered a period of expanded policy arenas which require broader agendas and applications, from long‐term‐care systems development to assisting employers who are creating flexible work and retirement programs. It is appropriate for the aging and developmental disabilities networks to explore the intersections of their operations with respect to their methods of administration, advocacy, service systems development, and policies.  相似文献

ABSTRACT

This paper considers the examination results of TVEI and non TVEI pupils in the database established at the University of Newcastle in 1985‐87. The pupils took national exams in the summer of 1987, when they were about 16 years old. Their average grades (Exam Means) and their accumulated grades (Exam Totals) were considered separately.

The Exam Mean and Exam Total scores were generally worse for TVEI than non TVEI pupils, even when pupils with the same ability test scores and aspirational scores were compared. However, it is possible that non TVEI factors caused the discrepancy in results and it is these factors which are the subjects of this paper.

The paper considers firstly whether the differences are an artefact of regression analysis. Secondly, the data are considered using various multilevel models. Both analyses suggest that there was no TVEI effect on the Exam Mean score and a negative TVEI effect on the Exam Total. Various explanations for these findings, concerning internal school allocational and curriculum policies, are considered and discussed.  相似文献

The teaching of a foreign language before ten or eleven years of age has always existed, but it is only since the second world war, and with the object of promoting better international understanding, among other things, that it has undergone extensive development, especially in the United States, Great Britain and France. As far as Europe is concerned, a meeting of all the European ministers of education was held in Hamburg in 1962; on this occasion the ministers stated that the teaching of languages was not giving satisfactory results, and they made recommendations intended to encourage  相似文献
