This article is the result of a master's thesis about children and their universal right to be included in a family environment. This is not only protected under international law, but also intuitive to human beings. HIV‐AIDS continues to threaten lives of children, particularly in sub‐Saharan Africa in the form of orphaning. Looking at a case study from Kenya, it is revealed that, while legal protection is yet to be fully realized in the state, strong cultural norms of value are alive. Currently, the extended family system is the greatest protection to children orphaned or at risk of being orphaned. However, this system was made invisible in the domestic laws of Kenya under the Children Act 2001. This neglect calls for questions not only regarding the protection cultural norms may offer, according to the best interests of children, but also as to the cultural environment being created with the new law.  相似文献

North American research on the policing of ‘domestic violence’ has been very influential among policy makers in Great Britain. In particular, research which purports to verify the deterrence value of arrest has prompted the establishment of over thirty domestic violence units in London and similar initiatives elsewhere in Britain. The paper will outline the nature of the traditional police response to ‘family violence’ in London and the nature of the experimental innovations. Changes in police practice with regard to this type of violence will be put in the context of the organizational constraints and possibilities of policing. Finally, changing police responses to domestic violence will be evaluated in terms of the debate over the possibility of using the state or its organs to achieve social change.  相似文献

Prior studies of recidivism have focused almost exclusively on individual‐level characteristics of offenders and their offenses to explore the correlates of reoffending. Notably absent from these studies are measures reflecting the neighborhood contexts in which individuals live. The current research addresses this shortcoming. Using data on a sample of ex‐offenders in Multnomah County, Oregon (Portland and surrounding area) in conjunction with 2000 census data, we answer two questions. First, which individual‐level factors influence rates of recidivism? Second, to what extent does neighborhood socioeconomic status account for variation in the reoffending behavior of ex‐prisoners that is not explained by their individual‐level characteristics? We find that those who return to disadvantaged neighborhoods recidivate at a greater rate while those who return to resource rich or affluent communities recidivate at a lesser rate, controlling for individual‐level factors.  相似文献

The results of additional validation studies of a sensitive microplate hemagglutination assay for ABO reverse grouping of bloodstains are presented. The results of the validation study demonstrate the reliability of the microplate assay for use in routine serological casework. Based on these studies, the microplate assay has now replaced the Lattes crust test for ABO reverse grouping of bloodstains in the FBI Laboratory.  相似文献
