HIV/AIDS is having profound impacts on livelihoods in sub-Saharan Africa. These include the deaths of working-age adults, the diversion of resources to caring, and the rupture of traditional chains of knowledge transmission. NGOs are responding by providing assistance to communities affected by the epidemic in the fields of agriculture, skills training, and microfinance, as well as by offering home care and support. A key feature of such initiatives is the focus on previously neglected groups such as women, school dropouts, and orphans. Factors of success include the use of participatory processes to identify target groups, and the involvement of local political leaders and adults trusted by young people in project activities. Challenges include improving monitoring systems, effectively disseminating lessons learned, and persuading donors, whose responses to the epidemic are currently focused on preventive and curative health services, to support livelihoods interventions as a matter of urgency.  相似文献

This article examines the rise of various representations of postcolonial states to highlight how thinking and practice that arose and prevailed during the Cold War still persists in the present ostensibly post-cold war era. After initially outlining the historical construction of the social sciences, it is shown how the annexation of the social sciences evolved in the early post-World War II and cold-war era as an adjunct of the world hegemonic pretensions of the USA. A critique is then developed of various representations of post-colonial states that arose in the making of the 'Third World' during the cold-war annexation of the social sciences. Yet such practices still persist in the present, as evidenced by more contemporary representations of post-colonial states commonly revolving around elements of deficiency or failure, eg 'quasi-states', 'weak states', 'failed states' or 'rogue states'. A more historicised consideration of post-colonial statehood, that recasts conceptions of state-civil society antagonisms in terms of an appreciation of political economy and critical security concerns, offers an alternative to these representations of 'failed states'. By historicising various representations of 'failed states' it becomes possible to open up critical ways of thinking about the political economy of security and to consider alternative futures in world order.  相似文献

The frequency of serial sexual murder has been widely discussed, and estimates of the number of victims in the United States range from 500 to 6000 per year. This study attempted to quantify the number of serial sexual murder victims in Virginia for a ten-year period. Multiple sources of data were utilized, including Federal Bureau of Investigation (FBI) case files, FBI's Violent Criminal Apprehension Program (ViCAP) reports, Virginia State Police ViCAP reports, Virginia Homicide Investigators Association, and the Virginia Division of Forensic Science DNA database, to effectively cull out all the known serial sexual murder victims for the given time period. Review of these records revealed a total of 28 victims of serial sexual murder, compared with a total of 5183 murder victims for the same ten-year period. The frequency of serial sexual victimization was 0.5% of all homicides for the given period. These results highlight the unusual frequency of serial sexual murder.  相似文献

Global climate change is now one of the biggest challenges facing humankind in the twenty-first century. It is occurring at a time when China's economic rise is leading to substantial environmental problems combined with escalating demands on global resources. Many commentators have warned of impending economic collapse, rising social conflicts, and large-scale public health disasters. 1 It is not only China's modernisation drive that is at stake. The spill-over effects across borders also present security concerns at the regional and global levels. From a global security perspective, the emerging environmental crisis is generally cast in highly negative terms. Limited attention has been given to the question of whether China can adapt. In the case of climate change this is now an urgent task. On the Qinghai–Tibetan plateau climate impacts pose significant security risks for China and the Asia region. The ability to adapt is of critical importance to the future sustainability of these ecosystems as well as the millions of people they serve.  相似文献

Bolsa Família, the world's largest conditional cash transfer, provides welfare payments to 13 million Brazilian households – and creates dilemmas for Brazil's rural landless movement, the MST. Through ethnographic analysis in two villages, this paper explores the daily practices and political conceptions of the program's beneficiaries. Bolsa Família does not, as is often believed, create a de-radicalizing sense of contentment. Instead, the program generates a temporality that makes the benefit feel unreliable to beneficiaries. These beneficiaries must mediate the tension between ‘citizen’ and ‘manager’ identities, the latter being a salient subject-position produced by Bolsa Família. The precarity of this position helps explain why Bolsa Família has not inspired significant mobilization by social movements.  相似文献

The safety of foster children and youth is the primary concern of the U.S. Department of Human Services. Yet, not all certified foster care homes offer the safety children need. This article reports the findings of a phenomenological study of foster youth reporting maltreatment occurring at the hands of foster parents. With a scarcity of studies on the abuse occurring at the hands of foster care providers, this study offers an important glimpse into the realities of life in care. Through in-depth interviews, this study reveals the harm perpetrated by foster care providers and the probable connection between maltreatment in care and barriers to academic achievement.  相似文献
