Previous research studies and anecdotal evidence portray shooting galleries as locales that place injection drug users at great risk for HIV infection, drug use and violence. Collectively, these studies highlight the need to intervene with injectors who frequent shooting galleries. However, few researchers have studied an often-forgotten risk group – women injecting drug users who frequent shooting galleries – and compared their risk behaviors to their male counterparts. To address this gap in the research literature and to evaluate the functionality of the shooting gallery as a setting for HIV prevention, we collected data on risk practices from 201 injectors (101 men and 100 women) who were recruited from eight shooting galleries in Miami, Florida. Results indicate that, compared with men, women injectors engaged in a similar variety and frequency of injection risk behaviors and had more shooting companions. While only minor gender differences were apparent, relatively few injectors – male or female – adhered to current recommendations for needle hygiene practices. Needle hygiene practices existed equally among injectors of both sexes, however very few adhered to current recommendations. Furthermore, contrary to common images of shooting galleries, use of other drugs was infrequently reported, episodes of violence or victimization were uncommon, and sexual contact almost never occurred. Operators of shooting galleries, both men and women, indicated their willingness to participate in HIV prevention efforts. Implications of these findings for HIV intervention indicate that (1) there is a great need to intervene with both men and women IDUs who frequent shooting galleries and that (2) shooting galleries can be an optimal setting for HIV prevention. 相似文献

The current poverty rate and the persistent poverty rate are both included in the European Union’s (EU's) portfolio of primary indicators of social inclusion. We show that there is a near-linear relationship between these two indicators across EU countries drawing on empirical analysis of EU-SILC and ECHP data. Using a prototypical model of poverty dynamics, we explain how the near-linear relationship arises and show how the model can be used to predict persistent poverty rates from current poverty information. In the light of the results, we discuss whether the EU's persistent poverty measure and the design of EU-SILC longitudinal data collection require modification. 相似文献

This article performs a sensitivity analyses of the synthetic T2 chart using fractional factorial design, which integrates the interaction effects. We are interested in the effects of the input parameters on the optimal cost, chart's parameters, and average run lengths. We also look at the input parameters responsible for the increase in cost and improvement in statistical performance under statistical constraints, and investigate how the input parameters influence the binding effect of the statistical constraints. The sensitivity analyses of the synthetic T2 chart are compared with that of the Hotelling's T2 chart, and parameters responsible for the cost advantage of the synthetic T2 chart are identified. 相似文献

The paper explores the relationship between the demographic transition and international migration, that is, between population dynamics and direct connectivity between peoples. The first part examines how ideas conveyed by migrants to non‐migrants of their community of origin are susceptible to impact on practices that lead to the reduction of birth rates in source countries of migration and concludes that international migration may be one of the mechanisms through which demographic transition is disseminated. The second part shows that declining birth rates in origin countries generate a new profile of the migrant and suggests that future migrants will typically leave no spouses or children in the home country and therefore their objective will no longer be to improve the family’s standing at home for the mere reason that there is no longer such a family, but to increase opportunities for themselves. Migration policies of origin countries on remittances as well as those of destination countries on family reunification will have to be reconsidered. 相似文献

We build a simple model of secession crises where a majority of voters may wish to accommodate a minority in order to prevent a secession attempt. We first show the existence of a majority voting equilibrium, where the median voter is decisive and most prefers a government’s type that is biased in favor of the minority. We propose a measure of the secession risk at equilibrium, which depends upon the comparison of the willingness to secede by the minority and to accommodate by the majority. We show that focusing only on the willingness to secede, as previous literature has done, is misleading when studying the impact on the risk of secession of the size of the minority region, the probability that a secession attempt by the minority is successful, and the cultural heterogeneity in the country. 相似文献

A range of studies have revealed the interrelatedness of identity construction, community formation and media among diasporas, mostly focusing on domestic contexts. Seeking to add further nuance to the understanding of the social lives of diasporas, we concentrate on media culture in the public environment of the film theatre. The significance of diasporic film consumption is investigated through a local audience study of Turkish film screenings in Antwerp. The phenomenon of the screenings was analysed through a multi-method approach, including 536 questionnaires among audiences, 19 in-depth interviews and 3 group interviews, along with previous findings (on distribution and exploitation) of the same project. The results show that Turkish films are almost exclusively attended by people with Turkish roots, creating a Turkish diasporic space within the boundaries of the urban and the public. The audience study shows that the screenings fulfil a major social role but also affect understandings of community. 相似文献
