Objective: To analyze the overlap of nonsuicidal self-injury (NSSI) and suicide-related behaviors (SRB) among college students with regard to demographics, mental health, and coping styles. Participants: Respondents were 572 undergraduate students at a southwestern public university. Methods: Data were collected in 2015. Respondents completed a demographic survey and assessments of NSSI, SRB, internalizing symptoms (ie, anxiety, stress, and depression), aggression, and negative coping strategies. The survey was administered via a Web-based procedure. Results: Women reported more frequent cutting behaviors than men. Endorsement of NSSI was also associated with an increased likelihood of lifetime SRB. A subgroup of students endorsing both NSSI and SRB demonstrated poorer mental health, more negative coping, and self-reported female sex. Conclusions: College healthcare providers may benefit from competency-based training in techniques for the combination treatment of NSSI and SRB, as well as culturally based models of suicide. 相似文献

Expressions for the entropy, the Kullback-Leibler information, and the I α-information are established for distributions of progressively Type-II censored order statistics. These results are used to identify minimum and maximum information censoring plans. In particular, we find minimum and maximum entropy plans for DFR, exponential, Pareto, reflected power, and Weibull distributions. The results for Kullback-Leibler and I α-information hold for any continuous distribution. 相似文献

Uniform order statistics generated by two simulation methods are compared by means of Pitman’s measure of closeness. This measure, as a probability, is shown to be asymptotically 1/2. Some results are also established for fixed points of the cumulative distribution function (CDF) for a uniform order statistic. These fixed points are important for calculations involving the joint distribution of these order statistics. 相似文献

In the model of progressive type II censoring, point and interval estimation as well as relations for single and product moments are considered. Based on two-parameter exponential distributions, maximum likelihood estimators (MLEs), uniformly minimum variance unbiased estimators (UMVUEs) and best linear unbiased estimators (BLUEs) are derived for both location and scale parameters. Some properties of these estimators are shown. Moreover, results for single and product moments of progressive type II censored order statistics are presented to obtain recurrence relations from exponential and truncated exponential distributions. These relations may then be used to compute all the means, variances and covariances of progressive type II censored order statistics based on exponential distributions for arbitrary censoring schemes. The presented recurrence relations simplify those given by Aggarwala and Balakrishnan (1996) 相似文献

Carol Cramer and Ellen Daugman of Wake Forest University discussed faculty attitudes toward ebooks in the library collection. Cramer and Daugman shared communication strategies based on their experience balancing the print book preferences of some faculty with the budgetary and collection development needs of the library. 相似文献

This article describes an investigation of the effects of a short-term educational intervention on graduate social work students’ attitudes toward lesbians and gay men, their knowledge about lesbian identity development and disclosure, and their anticipated professional behavior with lesbian clients. The author describes the importance of reducing homophobia among social work students and presents a theoretical framework for the educational intervention used in this study. Although knowledge acquisition significantly increased among students in both of the study’s treatment groups relative to the comparison group, and although students from one treatment group showed significant improvement in their attitudes toward gay men relative to the comparison group, neither treatment group significantly improved in their attitudes toward lesbians or their anticipated professional behavior with lesbian clients relative to the comparison group. 相似文献

ABSTRACTIn this article, we describe Food Landscapes, an interdisciplinary program involving youth who live in an urban community identified as a food desert. Food Landscapes combined socially engaged art-making, cooking, community engagement, and community service to open dialogue with youth about food justice and equity, the meaning of community, and the formation of meaningful relationships between youth and community members who have disabilities. We describe the program and discuss the theory and model bases for the program and lessons learned during program implementation. 相似文献

Quality of Life in a City: The Effect of Population Density 总被引:1,自引:0,他引:1
There exist a number of concepts andoperational definitions of quality of life. Inthe present study the aim has been to develop acomprehensive, global index of quality of life,and relate the sub-indexes and global index tovarious socio-demographic variables, somatichealth and density of population in theresidential area. The sample consisted of 2066individuals between 18 and 65 years old fromthe common population. Seven sub-indexes weredeveloped. They constituted one factor withmoderate intercorrelations between thesub-indexes. Good somatic health, living in astable relationship with a partner, preferablymarried, in a less densely populated area,having a good education, a good income andbeing a younger female were the independentstatistical determinants of global quality oflife. However, various sub-indexes were relatedto different socio-demographic variables. Agewas oppositely related to differentsub-indexes. The study shows the importance ofwhat type of quality of life is investigated.To our knowledge, this is the first study ofthe effect of population density on quality oflife. 相似文献
