The increased risk of violent victimization for adolescents relative to other age groups has recently become a major public health concern. The current study uses data from a multisite study of eighth grade youths attending public schools in 11 cities to determine the extent and nature of youth general and serious violent victimization among both sexes and five racial/ethnic groups in 11 diverse communities. This study explores differences in sex, race/ethnicity, and community independently and explores interactions between sex and community and race/ethnicity and community. Our findings suggest important differences in victimization prevalence and individual victimization rates by sex and community of residence. Racial differences were found to be closely tied to community. Policy implications resulting from our findings are discussed.  相似文献

We examined the DSM-IV criteria for pathological gambling as assessed with the DSM-IV-based Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002). We first analyzed the psychometric properties of the DIGS, and then assessed the extent to which performance on two judgment and decision-making tasks, the Georgia Gambling Task (Goodie, 2003) and the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994), related to higher reports of gambling pathology. In a sample of frequent gamblers, we found strong psychometric support for the DSM-IV conception of pathological gambling as measured by the DIGS, predictive relationships between DIGS scores and all cognitive performance measures, and significant differences in performance measures between individuals with and without pathological gambling. Analyses using suggested revisions to the pathological gambling threshold (Stinchfield, 2003) revealed that individuals meeting four of the DSM-IV criteria aligned significantly more with pathological gamblers than with non-pathological gamblers, supporting the suggested change in the cutoff score from five to four symptoms. Discussion focuses on the validity of the DSM-IV criteria as assessed by the DIGS and the role of cognitive biases in pathological gambling.  相似文献

ABSTRACT

Undertaking an examination of the precarious places of the movies and movie theaters in queer lives in the 20th century, this article takes up a series of anecdotal episodes and feature-length films to consider how the space-related stakes of LGBT health have been best understood in literal cinema houses and the narrative cinema projections inside of them. The author argues for an appreciation of LGBT-themed motion pictures as oscillating between perpetuator of queer pathology and its potential solution.  相似文献

This article examines the effects of undocumented Mexican immigrants on the earnings of other workers in geographical labor markets in the Southwest. The number of undocumented Mexicans included in the 1980 census in southwestern SMSAs is estimated. We then estimate the parameters of three specifications of a generalized Leontief production function with various demographic groups as substitutable factors. The statistically significant effects of undocumented Mexicans on the earnings of other groups are positive, but of slight magnitude. Legal immigrants' effects on native white earnings, however, are small and negative. The results are consistent with the possibility that undocumented Mexican immigrants' jobs complement those of other workers. The implications for public policy concerns about the effects of illegal Mexican immigration are discussed.  相似文献

In forecasting the effects of large-scale development projects on small town communities there is a need to consider the Aboriginal component of the population separately, not least to ensure the success of government policies regarding social welfare and Aboriginal advancement. This paper outlines some of the methodological and conceptual issues associated with the estimation of Aboriginal population change in the rapidly growing town of Katherine, in the Northern Territory, and reports on selected social and economic impacts of recent in-migration. Attention is drawn to the inappropriateness ofde facto population figures as a basis for planning and the need to estimate service requirements in the context of high population mobility.  相似文献

Public perception research in different countries has suggested that real and perceived periods of high temperature strengthen people's climate change beliefs. Such findings raise questions about the climate change beliefs of people in regions with moderate climates. Relatively little is known about whether public concerns about climate change may also be associated with perceived changes in other weather‐related events, such as precipitation or flooding. We examine the relationship between perceived changes in weather‐related events and climate change beliefs among U.K. residents at a time of below‐average winter temperatures and recent flooding. National survey data (n = 1,848) revealed that heat waves and hot summers were perceived to have become less common during respondents’ lifetimes, while flooding, periods of heavy rainfall, coastal erosions, and mild winters were perceived to have increased in frequency and cold winters were perceived to be unchanged. Although perceived changes in hot‐weather‐related events were positively associated with climate change beliefs, perceived changes in wet‐weather‐related events were found to be an even stronger predictor. Self‐reported experience of “flooding in own area” and “heat‐wave discomfort” also significantly contributed to climate change beliefs. These findings highlight the importance of salient weather‐related events and experiences in the formation of beliefs about climate change. We link our findings to research in judgment and decision making, and propose that those wishing to engage with the public on the issue of climate change should not limit their focus to heat.  相似文献

Researchers often use social indicators in their analysis of community problems and the subsequent proposals. However these researchers rarely consider the constraints placed on these indicators by construction and measurement problems. Some of these indicators are reviewed with particular reference to conceptualization of social phenomena and the intrusion of values. In the latter regard comment is made on the use of social indicators by political decision makers and policy planners.  相似文献

It is increasingly recognized that social work has a vital role to play in shaping effective responses to environmental degradation, climate change and disasters. Innovative teaching and learning strategies can be used to facilitate understanding of complex, interrelated and systemic social, economic and environmental challenges. This article shares the development and design of a new social work course entitled ‘Social work and sustainable social development’. Teaching methods and strategies are provided including individual and group mind maps, case studies and presentations, guest speakers and evaluation methods. Implications for social work education and the profession are discussed in order to build capacity to address environmental justice and sustainability.  相似文献

Anonymisation processes are an embedded, if contested, element of ethical research practice. Current debates, highlighting various challenges to anonymity, suggest the importance of situated ethics and negotiated solutions. However, the strategies adopted are necessarily mediated by the researcher’s epistemological positions. Longitudinal studies with their extended timeframes and intensive research relationships tend to amplify ethical dilemmas and highlight the contingency and fluidity of ethical processes. Here we explore how temporality intersects with epistemology in a qualitative longitudinal (QL) study of organisations located in a contemporary policy context. We reflect on the confidentiality and anonymity dilemmas that develop and change over time, the strategies adopted and the implications of these for the type of knowledge produced. We suggest that QL studies entail flexibility within epistemological frameworks. These issues have particular resonance and consequences for researchers in light of contemporary pressures around public scrutiny of academic performance and wider debates around public sociology.  相似文献
