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

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

A growing body of evidence shows that minorities are disproportionately the targets of police brutality, but important theoretical questions about the causes of that inequity remain unanswered. One promising line of research involves structural‐level analyses of the incidence of police brutality complaints; however, existing studies do not incorporate variables from alternative theoretical explanations. Drawing on the community accountability hypothesis and the threat hypothesis, we tested the predictions of two prominent structural‐level explanations of police brutality in a study of civil rights criminal complaints. The study included cities of 150,000+ population (n = 114). The findings reveal that two community accountability variables—ratio percent Hispanic citizens to percent Hispanic police officers and the presence of citizen review—were related positively to police brutality complaints, partially supporting that perspective. Two threat hypothesis measures of threatening people—percent black and percent Hispanic (in the Southwest)—were related positively to complaints, as predicted. The relative degree of support for the two hypotheses is assessed. 相似文献

Physical violence occurs in 11–12% of same‐gender couples, which suggests that domestic violence is an abuse of power that can happen in any type of intimate relationship, regardless of gender or sexual orientation. Although incidents of violence occur at the same rate in same‐gender couples and cross‐gender couples, the violence appears to be milder in same‐gender couples and it is unclear what percentage of same‐gender violence should be characterized as abuse or intimate terrorism. Same‐gender victims also suffer from the additional stress of severe isolation and the abuser's threats to expose the victim's sexual orientation in a hostile manner. 相似文献

This research note builds on recent results of the literature on presidentialism to develop a new measure of presidential power. The Index of Presidential Power (IPP) differentiates three dimensions: legitimacy, legislative and non‐legislative powers. The IPP can be used for all types of governmental systems in different political regimes. For the first time the IPP estimates presidential power granted by the constitution in all 28 post‐communist countries. This information is collected in the IPP data set, which is used to carry out analyses at the aggregate level as well as at the level of the individual presidential power dimensions. Results show that the semi‐presidential category is of little use. The comparison of the IPP with alternative indices of presidential power in post‐communist countries indicates that political analysis should give more attention to presidential power structures. 相似文献
