The authors assessed the influences of several risk factors—self‐esteem, history of unwanted sexual contact (USC), depression, and sorority membership—on eating‐related and weight‐related attitudes and behaviors. Findings provide support for the roles of self‐esteem, depression, and USC on restricting attitudes. According to the authors' model, these independent variables predicted restricting attitudes that then predicted restricting behaviors. Implications for preventive interventions and the study's limitations are discussed.  相似文献

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

It has been suggested that the field of Mind, Brain, and Education (MBE) requires a stable infrastructure for translating research into practice. Hinton and Fischer (2008) point to the academic medical center as a model for similar translational work and suggest a similar approach for linking scientists to research schools. We propose expanding their model to include a formal role for clinicians. Including clinicians who work with children with learning problems brings an important perspective to the translational work. For example, the integration of the concept of “differential diagnosis,” a core precept in clinical medicine, would bring needed diagnostic specificity to the field of MBE. We describe a virtual infrastructure for collaboration, or “collaboratory,” consisting of research scientists, educators, and clinicians, linked to an academic institution. We anticipate that MBE graduates can play a critical role in the collaboratory model. With additional training, they can become “neuroeducators” capable of moving comfortably among the disciplines, building linkages, fostering communication, and facilitating collaboration.  相似文献

Abstract

Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable.  相似文献
