This note analyses a recent case of the English Court of Appeal in which the applicant, R.G., a gay, H.I.V. positive Colombian claimed asylum on grounds of persecution due to his sexuality. Both the Asylum and Immigration Tribunal and the Court of Appeal rejected R.G.’s claim for asylum. The Court of Appeal’s first and most significant reason was that the alleged persecution was not sufficiently serious or life threatening, since R.G. had not suffered actual physical violence throughout the 13 years that he had lived as a closeted gay man in Colombia. Secondly, the court considered the real reason for R.G.’s seeking asylum was his desire to access free health care in order to manage his H.I.V. His allegations of persecution on the grounds of sexuality were viewed as a sham. This note is critical of the approach taken by the Court, which, it is argued, displays an insensitivity to the complexity of sexual identity and its performance and has the effect of perpetuating and legitimating discrimination against lesbians and gay men.  相似文献

Data were collected from three studies over an eight–year period, which produced a sample of 868 female college students at a southern university. The three data sets were combined to permit an assessment of the extent to which reported victimization occurred among students before coming to the university rather than during their college experience, and to examine the nature of force in intimate relationships among maturing adolescents. About half of the subjects reported that their last victimization occurred while in high school, thus they were younger and less mature at the time of their victimizations. The researchers note that these two factors raise concern as adolescent girls may not be prepared to adequately define or protect themselves from inappropriate use of force in dating relationships, as the literature reports that both the development of sexuality and a redefinition of the use of force in childhood play are occurring at this point in their development, increasing the potential for victimization.  相似文献

This paper considers the morally relevant ways in which population-based research is a distinct type of human subjects research that have unique moral considerations relevant for public health practitioners and researchers. By defining population-based research, the authors distinguish it from public health practice and then consider, in more detail, the ways in which population-based research differs from clinical human subjects research. Based upon the distinctions between these types of research and practice, they identify five important issues that arise in the design and conduct of certain kinds of population-based research. The authors hope that public health practitioners find these distinctions useful in determining when their work may actually be population-based research and that public health researchers use them to identify the areas where ethical issues in their research may arise.  相似文献

Water conservation policy is a natural laboratory for addressing general issues of relevance to policy analysis and public administration, particularly the relative effectiveness of policies in changing human behavior. Using multivariate regression analysis of a dataset comprised of more than 200,000 monthly observations of more than 19,000 household accounts over six years, this paper makes three main contributions. First, it contributes to the substantive area of water conservation policy by analyzing what works. Second, it contributes to our understanding of generic policy instruments. Third, it raises an important issue regarding standard assumptions about selection bias. The results support earlier work warning that offsetting behavior can negate engineering solutions to policy problems, but further indicate that adding communication to engineering solutions can create cooperation that overcomes offsetting behavior. They also provide evidence that appropriate regulation can be effective, and that pricing can be effective even when price elasticities of demand are low.  相似文献
