The Impact of Rainfall on the First Out-Migration: A Multi-level Event-History Analysis in Burkina Faso 总被引:2,自引:0,他引:2
Using event history analyses, we investigate the impact of rainfall conditions — a crucial environmental factor in the livelihood of Sahelian households— on the risk of the first village departure in Burkina Faso. The distinction of migrations by destination and duration proves critical in studying this relationship. Findings suggest that people from the drier regions are more likely than those from wetter areas to engage in both temporary and permanent migrations to other rural areas. Also, short-term rainfall deficits tend to increase the risk of long-term migration to rural areas and decrease the risk of short-term moves to distant destinations. 相似文献

ABSTRACTThe article assesses and analyzes different dimensions of the current configuration of North/South dialogues within gay-lesbian and queer studies, with particular attention to the interrelations between the United States and South America. It looks into how gay-lesbian and queer studies relate to the global division and hierarchy of intellectual labor traditionally embedded in academic practices, and it asks whether the scope of its radical program includes a revision of unequal academic dynamics. Its concerns are both ethical and epistemological, as they speak not only to the moral and political dimensions of academic practice, but also to how these modes affect the knowledge produced in the United States and in South America today. By offering a view from the South conversant with South American as well as Northern production, we hope to contribute to both local and international debates regarding the present and future of the field. 相似文献

ABSTRACTThe anthropocene is often discussed as an era of ‘new’ environmental changes that require unprecedented forms of societal adaptation, one example being climate-induced resettlement. Yet discussions of the anthropocene can also be better contextualized in terms of their featuring certain phenomena as ‘new’ that are really much more longstanding phenomena. For example, many Indigenous peoples have ancient traditions of environmental ‘mobility.’ This essay reviews some of the history of Indigenous philosophies, especially Anishinaabe, of mobility, migration, and resettlement. Often these philosophies focus on fluid and transformative relationships as constituting the fabric of resilient societies. Indigenous traditions of mobility are critically relevant for climate justice. They put into relief how colonial power can operate as a containment strategy that works to curtail mobility. In this way, looking at Indigenous mobility in the anthropocene involves unraveling layers of colonialism where containment has been widely imposed. This claim can be used to signal some of the dangers of centering the causal role of climate change in certain cases societal movement. To further support our claims, the essay concludes with a brief analysis of some of the literature and testimonies on resettlement in the Gulf of Mexico and Alaska. 相似文献

The last century has seen extraordinary growth in human populations and economies. This growth has imposed huge and ever-increasing
pressures on Earth’s ecosystems, prompting fears concerning the integrity of their life-supporting functions and the high
rate of extinction of species. Quite simply, ecological degradation threatens the interests and possibly the survival of future
human populations. By the criterion of ecological sustainability, and given our current consumption rates and technologies,
Earth is now overpopulated. In such times of great and threatening change it is important to reconsider human goals and enabling
strategies. A fundamental goal is the sustained quality survival of human populations. Achieving this requires new paradigms
of understanding and management, especially the realization that the human economic and social spheres are dependent on healthy,
functioning ecosystems, and that most forms of growth are unsustainable. Socio-economic development must become ecologically
sustainable with the maintenance of Earth’s life-support systems assuming priority. Developing integrated ecosystem management,
cutting consumption, and negotiating optimum population sizes would be useful. This paper discusses these issues with emphasis
on the Australian situation. 相似文献

Many foster parents are ill prepared to meet the behavioral needs of children placed in their homes. Research suggests they lack training in evidence-based behavioral interventions and feel unsupported by child welfare professionals. Given the complex needs of foster children and increased rates of placement disruption for foster children with behavior problems, implementation of effective interventions is essential. However, little is known about foster parents' receptivity to these types of interventions. In this qualitative study, we examine urban foster parents' perceptions of the specific elements of parent management training (PMT), an evidence-based treatment for disruptive behaviors that teaches parents to improve desired behaviors and decrease oppositional behaviors by rewarding positive behaviors (positive reinforcement) and responding to negative behaviors with mild, consistent punishments such as timeout or a privilege removal. We present data from four focus groups (N = 38). While the questions focused on parent's perceptions of PMT, responses often related to parent interactions with agency staff. Four strong themes emerged from the data. First, foster parents discussed a need for more support and training in how to address children's behaviors, but also had concerns that some PMT discipline techniques would be ineffective based on their past experiences with foster children. Second, they described how staff communication skills and allegations of child abuse could affect parents' motivation to continue fostering. Third, they expressed a need for more detailed information about children's histories and visits with biological families as the lack of information contributed to difficulty in meeting foster children's needs. They suggested that joint training of foster parents and staff in the intervention could improve their ability to work together to support the child's positive behaviors. Finally, parents reported little involvement in child mental health services and doubted the effectiveness of the mental health services their foster children received. 相似文献
