Identity-based conceptualizations of sexual orientation may not account adequately for variation in young women’s sexuality. Sexual minorities fare worse in psychosocial markers of wellbeing (i.e., depressive symptoms, anxiety, self esteem, social support) than heterosexual youth; however, it remains unclear whether these health disparities exclusively affect individuals who adopt a sexual minority identity or if they also may be present among heterosexually-identified youth who report same-sex attractions. We examined the relationship between sexual attraction, sexual identity, and psychosocial wellbeing in the female only subsample (weighted, n = 391) of a national sample of emerging adults (age 18–24). Women in this study rated on a scale from 1 (not at all) to 5 (extremely) their degree of sexual attraction to males and females, respectively. From these scores, women were divided into 4 groups (low female/low male attraction, low female/high male attraction, high female/low male attraction, or high female/high male attraction). We explored the relationship between experiences of attraction, reported sexual identity, and psychosocial outcomes using ordinary least squares regression. The results indicated sexual attraction to be predictive of women’s psychosocial wellbeing as much as or more than sexual identity measures. We discuss these findings in terms of the diversity found in young women’s sexuality, and how sexual minority status may be experienced by this group.  相似文献

传统的手枪射击训练模式只注重训练技术和技术练习的结果,不重视练习的过程是否符合公安执法特点,导致手枪射击练习模式是"为打靶而训练",这是严重脱离实战的,必然严重影响警察战斗力的提升。要扭转这一现实就必须转变观念,要建立"为实战而训练"的观念,使训练紧紧围绕"实战"这个核心思想,注重训练警察执法实战所需的技能、意识、程序以及规范性。  相似文献

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are discussed.  相似文献

Investigating why people use the hospital emergency department (ED) for visits considered medically nonurgent can enhance our understanding of people's expectations of health care services, of their conceptions of prudent lay judgment, and of difficulties in negotiating the logistics of primary care services. This study identified reasons for such ED use from users' perspectives in both pediatric and adult visits. Respondents were asked to explain what brought them to the ED and to define an emergency. The study was conducted in two northeastern U.S. hospital EDs. The analysis drew on a convenience sample of 408 (331 pediatric, 77 adult users) face-to-face interviews that employed both open- and closed-ended questions. Findings indicate most patients had medical insurance and a regular place of care and most arrived by car or taxi. Twelve main themes emerged under three main categories: conceptions of needs, appropriateness, and preference for the ED. The findings indicate that various reasons for ED use may be construed as access issues. These include beliefs regarding limited availability of after-hour consultation services and of timely appointments at one's primary care site. Drawing on the findings, a typology that distinguishes between groups of users according to their preference for the ED, a level of congruence between their own reason and their definition of an emergency was developed. The typology suggests that people's concerns that influence their decision to come to the ED cannot be solved simply by expanding primary care services or by educational interventions. Its application yields recommendations for services and interventions.  相似文献

为响应公安部提出的:“向教育要警力,向教育要战斗力”的号召,目前各地公安院校都开设了查缉战术课。查缉战术课要贴近实战,要出战斗力就必须改革教学观念;改变教师知识结构,扩大知识面;加强校际交流,建立教学与实践结合机制;加强教学器材与设施建设。  相似文献

影像模糊问题,是警务现场照相工作中需要解决的一个基本的、关键的问题。目前,我国对于影像模糊的后期处理方法,还没有太多的对策,因此,前期影像录入过程中确保避免影像模糊现象的出现,成了警务现场照相工作中亟待解决的重要课题。本文旨在分析径向模糊、抖动模糊形成原因的基础上.讨论了如何有效地避免上述影像模糊的途径与方法,对于影像模糊现象的专项研究具有一定的参考价值。  相似文献
