The article scrutinizes the emergence and expansion of EU-related professions and forms of occupation from a field-analytical perspective. Starting from the observation that the EU is not just an influential political actor, but also an expanding area of work, expert involvement and job specialization the paper discusses various forms, dimensions and loci of the ongoing “professionalization” of Europe. It is shown that the expansion of EU-related professional activities is not just a phenomenon of Brussels and the “Eurocracy”, but has expanded into the member states and various areas of occupational activity and expertise. The EU professionalization is conceptualized as a transnational field of specialization and professionalization which produces own principles, forms of knowledge and resources which are used and reproduced by experts and specialists. The field perspective allows identifying common principles, but also the variance and transnational dimension of EU affairs. 相似文献

Many adolescents living in contexts characterized by adversity achieve positive outcomes. We adopt a protection–risk conceptual framework to examine resilience (academic achievement, civic participation, and avoidance of risk behaviors) among 1,722 never-married 12–19 year olds living in two Kenyan urban slums. We find stronger associations between explanatory factors and resilience among older (15–19 years) than younger (12–14 years) adolescents. Models for prosocial behavior and models for antisocial behavior emerge as key predictors of resilience. Further accumulation of evidence on risk and protective factors is needed to inform interventions to promote positive outcomes among youth situated in an ecology of adversity. 相似文献

Most research on the impact of Welfare Reform has been upon the employment status of parents and trends in declining caseloads. Recent research has examined how children in Temporary Assistance to Needy Families (TANF) program families are faring, with growing interest in the effects upon children of the disruptions to cash benefits that result from program sanctions, the policies that are intended to motivate parents to comply with work requirements. Adding to the body of knowledge on children and TANF sanctions, this study used administrative data to examine school attendance rates and disruptions to enrollment, for children from families with at least one sanction. Findings indicate that there are important probable connections between the factors that contribute to challenges to employment that relate to parenting and the school engagement of children in TANF families. 相似文献

AbstractWatershed development (WSD) projects in India are key to meeting a range of human development goals in rain-fed agrarian landscapes. However, outcomes are often observed to be partial and short-lived. We offer a novel perspective on the reasons. Our analysis shows that the dominant ‘water narratives’ of WSD policy and practice and the lived experience of local people contribute to a naturalisation of water scarcity, resulting in widespread views that WSD is primarily a means for increasing irrigation water supply. We show how this over-simplifies the complex problem of agricultural water use and perversely contributes to a continuing experience of water scarcity rather than its resolution. 相似文献

AbstractBeyond all the material and economic losses that natural disasters produce, post-disaster environments can alter the social capital of a community by affecting social norms, attitudes, and people’s behaviour. To analyse this issue, we empirically investigate the effect that the aftermath of a disaster can have on trust and reciprocity of people within communities. We do this by comparing outcomes of trust games conducted in earthquake-affected and non-affected rural villages one year after the 2010 Chilean earthquake. Our findings show that while trust levels do not differ across cases, reciprocity is lower in earthquake-affected areas. 相似文献

AbstractThis article employs an innovative methodology to study causal mechanisms in the oil–conflict link by combining a systematic approach with taking into account country details. Engaging in a deductive test of causal mechanisms in a controlled comparison of four major oil exporters, results show that no oil-related causal mechanism can fully explain the differences in violence. A more inductive analysis complemented by process tracing suggests a more comprehensive mechanism: oil contributes to the formation of opposition through grievances. Levels of violence, however, vary largely according to non-oil conditions – particularly the cohesiveness of opposition and the reaction of government to challengers. 相似文献

AbstractRural producer associations are considered a potential community-driven solution to the problems of smallholder agriculture. This article evaluates the impact of organising female farmers into producer associations in Gujarat, India. The initiative provided training, information, access to inputs, risk mitigation, and market linkages. Over 18 months, the programme weakly increased members’ non-farm income and access to output markets. It had stronger impacts on members’ awareness and utilisation of financial services. Impacts were heterogeneous, varying by pre-existing socioeconomic conditions. These findings suggest that producer associations can lower transaction costs for smallholders, but that poverty alleviation may be a longer-term prospect. 相似文献
