To review and analyze the scope of practice of health promotion services and draft standards of quality indicators for higher education communities, the American College Health Association (ACHA) initiated a Task Force on Health Promotion in Higher Education in May 1996. Members of the task force developed a National Survey on Health Promotion and Education in Institutions of Higher Education and mailed the survey to a stratified random sample of 600 ACHA member institutions, as well as to 97 key "best-practice health promotion leaders". The larger sample produced a 75.3% response rate, and 90.7% of the key informants returned usable surveys. The authors report selected findings from both groups that chronicle the state of health promotion practice in higher education at the close of the 20th century. The task force used the findings to establish a data-driven framework for the Year 2001 Standards of Practice for Health Promotion in Higher Education. 相似文献

We present a new biclustering algorithm to simultaneously discover tissue classes and identify a set of genes that well-characterize
these classes from DNA microarray data sets. We employ a combinatorial optimization approach where the object is to simultaneously
identify an interesting set of genes and a partition of the array samples that optimizes a certain score based on a novel
color island statistic. While this optimization problem is NP-complete in general, we are effectively able to solve problems
of interest to optimality using a branch-and-bound algorithm. We have tested the algorithm on a 30 sample Cutaneous T-cell Lymphoma data set; it was able to almost perfectly discriminate short-term survivors from long-term survivors and normal
controls. Another useful feature of our method is that can easily handle missing expression data. 相似文献

A distribution function is estimated by a kernel method with a poinrwise mean squared error criterion at a point x. Relation- ships between the mean squared error, the point x, the sample size and the required kernel smoothing parazeter are investigated for several distributions treated by Azzaiini (1981). In particular it is noted that at a centre of symmetry or near a mode of the distribution the kernei method breaks down. Point- wise estimation of a distribution function is motivated as a more useful technique than a reference range for preliminary medical diagnosis. 相似文献

Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self‐labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV‐seropositive men who have sex with men. The majority of participants (88%) identified as a “top, “ a “bottom, “ or “versatile. “ Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self‐labels, sexual behaviors of self‐label groups were greatly overlapping. Differences were found among self‐label groups in gay self‐identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self‐labels in addition to asking about sexual behavior. 相似文献

Abstract The authors examined the relationship between binge drinking and other substance use among US college students, using nationally representative data from the 1995 National College Health Risk Behavior Survey implemented by the Centers for Disease Control and Prevention. Compared with nonbinge drinkers, current binge drinkers were significantly more likely to report “ever” using and current use of cigarettes, marijuana, cocaine, and other illegal drugs. The researchers also found that the more often students binge drank, the more likely they were to have ever used cigarettes, marijuana, cocaine, and other drugs, and the more likely they were to report current use of cigarettes and marijuana. Those who design programs to prevent binge drinking and use of other substances should take into account the reality that many students use more than one substance and that the more frequently students report binge drinking, the more likely they are to be using other substances as well. 相似文献

In this article we explore the role of differentiation of self in facilitating forgiveness in the context of couple and family relationships. Differentiation is defined from the Bowen perspective as the ability to connect with others without being excessively emotionally reactive to the ebb and flow inherent in all significant relationships (being able to connect to others yet also being able to self‐regulate). Forgiveness is described as the releasing of an emotional injury via a complex psychological and relational process that is less an act of will than a discovery or possibility through understanding and empathy. Differentiation of self is related to emotional intelligence and empathy. The developmental and relational benefits of such are illustrated and discussed. A rationale for viewing differentiation and forgiveness in a contextual, historical, and relational attachment paradigm is suggested. Relevant clinical cases illustrate the dynamics of differentiation and forgiveness as discovery in the context of an understanding and empathic relational environment. 相似文献

This paper uses longitudinal survey data to assess factors affecting the duration of unemployment in Russia. We examine four
types of marginalised labour force participants, according to ILO guidelines and survey responses, and we estimate duration
models for each type. It turns out that the sets of characteristics with the strongest effects on the duration are remarkably
similar across the different unemployment definitions and model specifications. Therefore, despite the formidable practical
measurement problems, problematic groups of individuals can actually be identified.
