Epidemiological studies have found that young men who have sex with men (YMSM) represent the majority of young people infected with HIV annually in the United States. Further, they are one of the few risk groups to show an increase in the rate of infections in recent years. In addition to these disparities in prevalence and infection rates, there is an inequity in prevention and intervention research on this population. The purpose of this article is to review the existing YMSM literature on HIV epidemiology, correlates of risk, and intervention research. The article concludes that promising future directions for basic research include a focus on multiple clustering health issues, processes that promote resiliency, the role of family influences, and the development of parsimonious models of risk. In terms of intervention research, the article suggests that promising future directions include Internet-based intervention delivery, integration of biomedical and behavioral approaches, and interventions that go beyond the individual level to address partnership, structural, community, and network factors.  相似文献

Abstract

This paper outlines the limitations of a technical rationalist approach to HRD practice without seeking to negate it. It then offers a complementary view based on Schon's notion of the reflective practitioner which exhorts HRD practitioners to embrace complexity and reflection. We outline, first, a number of dimensions of diversity which confer complexity upon HRD practice, and, second, a series of suggested questions that may aid the framing of practical problems in a more effective way than might be the case with a purely technical rationalist approach. We urge novice (and expert) HRD practitioners to adopt a mind set that is contemplative of the diversities that they may encounter in practice and which is conjectural with regard to how these diversities may impact upon problems and their solutions.  相似文献

This study found that moral reasoning predicts intention to act in an ethical dilemma, but that this behavior is not modified by gender differences. Fishbein and Ajzen’s Reasoned Action model was used to predict intention to act in ethical dilemmas, while the Kohlberg and Gilligan paradigms of moral reasoning were introduced as exogenous variables. The theory of reasoned action model was found to be a good predictor of intention as hypothesized. Suggestions for further research are included. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Objectives. The purpose of this study is to assess if students enter charter schools at an academic disadvantage compared to students who make other types of school‐choice decisions, such as transferring between district schools, from a charter to a district school, or staying in the same school. We assess the demographic and academic characteristics of students prior to choosing to attend a charter school in comparison to students who made other types of school‐choice decisions and broaden the operational definition of a “disadvantaged” student when exploring differences between charter and district students to include academic achievement prior to entering a school. Methods. The analysis is conducted with student‐level panel data and a progressive series of ANCOVA models that were estimated using ordinary least squares (OLS) regression. This methodology allows for a comparison of the mean differences in academic achievement among students who made different types of school‐choice decisions while controlling for student‐level covariates. Results. Students who transferred from district to charter schools had the lowest levels of prior academic achievement compared to students who made other types of choice decisions. Conclusions. When Arizona charter authorizers face the deluge of renewal decisions that are approaching, the quality of education available to the next generation of charter school students is at stake. Renewal decisions will impact what choices are available going forward and, given the comparative academic disadvantage of charter school students prior to entering, those decisions should take into consideration the starting point for students entering charter schools.  相似文献

This study examines the determination of wage rates for nurses in hospital employment. Of particular concern is the effect of the recent increase in unionization by nurses on their wages, both directly and indirectly via threats from competing hospitals’ unionization. To improve on earlier work, the data are disaggregated and gathered from only one state to standardize for the legal, licensing, and reimbursement systems. We also look at the difference between highly skilled professional nurses, RN’s, and more general and less professional nurses, LPN’s. The results show that working conditions and competition in the market influence the wage rate as one would expect. The unionization of nurses, however, affects the wage levels differently for the two groups. We would like to thank Professors Robert Higgs and Alan Childs of Lafayette College, Professor David Fairris of Williams College, Professor James C. Luzier of Muhlenberg College, and an anonymous referee for their helpful comments and suggestions.  相似文献
