The purpose of this study was to develop a better understanding of why college students seek psychological treatment by examining indicators of psychological distress. A secondary goal was to assess the utility of screening for treatment need via a brief self‐report measure of distress. Two samples (1 clinical, 1 nonclinical; N= 8,380) were examined via logistic regression analyses to identify meaningful predictors of treatment‐seeking behavior. Clinical applications are discussed. 相似文献

本文以聚醚砜(PES)为膜材料,聚乙烯吡咯烷酮(PVP)、聚乙二醇(PEG)-400为添加剂,N,N-二甲基乙酰胺(DMAC)为溶剂,用非溶剂致相分离法制备了超滤膜——聚醚砜中空纤维超滤膜。通过正交试验法探索喷丝头距离水面的高度、凝固浴的温度、PES浓度、PEG-400浓度等因素对膜性能的影响,同时进一步研究了三个因素对成膜性能的影响规律,分析并确定了制备PES中空纤维超滤膜的最佳实验条件为:喷丝头距离水面的高度20cm,凝固浴温度318K-328K,PES浓度为18%。 相似文献

对目标污泥进行试验分析,获得最佳工艺条件后将含油污泥在经搅拌后静置分离,原油回收,泥水经机械脱水过滤。过滤后油泥利用氧化钙将除油后污泥在干燥反应器内发生的热化学反应,将细胞水在反应器内大部分蒸发,达到脱水、杀菌等目的。利用微波加热器将部分低温蒸汽加热至250℃以供再次强化干燥。经试验测定,经增钙干化后处理污泥含水率控制在35%以内。 相似文献

Along with informed consent, anonymization is an accepted method of protecting the interests of research participants, while allowing data collected for official statistical purposes to be reused by other agencies within and outside government. The Decennial Census, carried out in a number of countries, including the United Kingdom, is a major event in the production of research data and provides an important resource for a variety of organizations. This article combines ethical evaluation, a review of relevant law and guidance, and analysis of 30 qualitative interviews (carried out during the period of the 2001 UK Census), in order to explore the adequacy of the current framework for the protection of informational privacy in relation to census data. Taking account of Nissenbaum's concept of “contextual integrity,” Vedder's concept of “categorical privacy,” and Sen's call to heed of the importance of “actual behavior,” it will be argued that the current “contractarian” view of the relationship between an individual participant and the organization carrying out the Census does not engage sufficiently with actual uses of data. As a result, people have expectations of privacy that are not matched by practice and that the current normative—including the governance—framework cannot capture. 相似文献

The Institute of Education Sciences has funded more than 100 experiments to evaluate educational interventions in an effort to generate scientific evidence of program effectiveness on which to base education policy and practice. In general, these studies are designed with the goal of having adequate statistical power to detect the average treatment effect. However, the average treatment effect may be less informative if the treatment effects vary substantially from site to site or if the intervention effects differ across context or subpopulations. This article considers the precision of studies to detect different types of treatment effect heterogeneity. Calculations are demonstrated using a set of Institute of Education Sciences funded cluster randomized trials. Strategies for planning future studies with adequate precision for estimating treatment effect heterogeneity are discussed. 相似文献

Health professions are increasingly focusing on the development of integrity and professionalism in students of Health disciplines. While it is expected that Health students will develop, and commit to, the highest standards of conduct as undergraduates, and henceforth through their careers, the pressures of assessment and external commitments may lead to both unintentional and intentional plagiaristic behaviours. Exponential growth in Internet resources and new information technologies, as well as individual belief systems or naivety about the authorship attribution convention, suggest complexity in understanding the risks and factors associated with academic plagiarism. This paper reviews the education literature to provide an insight for academics into reasons for student plagiarism and, where possible, management of these risks. Our review refers to the health professions as a discipline in which academic conduct in students should be at the highest possible standard. 相似文献
