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

Recent articles on the gifted self are characterized by theoretical confusion and lack of definitional clarity. This article, anchored in current self psychology theory, defines the self experience as the person's subjective experience of organization and meaning, the maintenance of which is crucial to normal functioning. Interactions with others are a formative part of the self experience. Traits of giftedness, and the reactions of others to these, contribute to the gifted self experience. Social and emotional problems of giftedness, such as those that arise with asynchronous development and perfectionism, are based on a compromised sense of cohesion and unity of the self experience.  相似文献

Previous attempts to examine the effects of different types of text format on reading have focused on the improvement of reading. The present study investigated the effect of using a text format that might be predicted to disrupt reading. In this study 56 individuals were presented with reading material presented in right-justified format and in'ragged'uneven line format. Subjects performed significantly worse on right-justified material. Subjects who were classified as good readers on the basis of a pretest were more affected than poor readers. It is suggested that this may result from differences in the reading style of good and poor readers.  相似文献

Persistent school shootings have generated ongoing pressure to assess and enhance crisis communication effectiveness via strategies such as resilience-building and post-crisis restoration. A network perspective offers a robust, multilevel approach for examining complex information flows among community, campus, and individual actors affected by crises. Drawing on relational and structural embeddedness and Uncertainty Management Theory, we offer nine propositions that help explain structural and relational changes in a network over time. Although theoretically driven, these propositions are primarily functional, offering practical implications for safety officials and administrators trying to understand, prepare for, and respond to crises. Thus, we suggest measures and recommendations to improve information flow, uncertainty management, and resilience before, during, and after a crisis.  相似文献
