Policymakers have actively pursued urban renewal and dispersal programs to deconcentrate poverty in urban neighborhoods. Relocation strategies lead to new housing opportunities and may encourage employment opportunities for relocated residents if resourceful contacts and job information become more easily available after the move. This study provides an innovative evaluation of the early impacts of involuntary relocation programs in the Netherlands on the housing careers, earnings and employment rates of forced relocatees. It establishes a quasi-experimental design by employing unique longitudinal individual-level population registry data from Statistics Netherlands: forced relocatees are tracked and matched to a control group consisting of similar residents that were not forced to move. A difference-in-difference design shows that forced relocatees are living in less deprived neighborhoods after the move. However, we find no conclusive evidence that this upgrade in housing leads to more socioeconomic opportunities for the forced relocatees. 相似文献

In times of perception politics, the credibility of electoral candidates is a crucial asset in political marketing. This raises the question to which political leaders citizens attribute credibility and how political credibility is gained and lost through media performance. We analyze and compare two contrasting cases during the Dutch parliamentary election campaign of 2010. Whereas in this campaign Mark Rutte—leader of the liberal party VVD—gained credibility, the credibility of Job Cohen—at the time, leader of the social-democratic PvdA—waned substantially. To understand this we extend the source credibility approach with a dramaturgical approach, and as such we shed light on what happens in the dynamic, interactive process between leaders and audiences in which credibility is constructed. 相似文献

AbstractThe cross-country empirical evidence for the natural resource curse is ample, but unfortunately fraught with econometric difficulties. A recent wave of studies on measuring the impact of natural resource windfalls on the economy exploits novel datasets such as giant oil discoveries to identify effects of windfalls, uses natural experiments and within-country econometric analysis, and estimates local impacts. These studies offer more hope in the search of quantitative evidence. 相似文献

This article compares strategic public sector HRM practices between 10 small countries that have consistently shown extraordinary economic, social, and governance performance. The fact that these small countries, which are traditionally considered to be disadvantaged, have become benchmarks of good government suggests they have uniquely maximized and leveraged their key resource: people. In search of novel lessons, we assess through secondary data how their public sectors have organized and institutionalized four key HRM activities: 1) selection, 2) appraisal, 3) training, and 4) compensation, and whether they engage in strategic, centralized efforts to architect and “bundle” these activities. Our exploratory case study findings show that these high performing countries employ various integrated efforts to attract the best and brightest into their public sectors, and train and reward them well, although they differ in terms of their centralization dynamics. We conclude our article with seven propositions for future research and implications for emerging small countries. 相似文献

Faced with pressing climatic changes, scientific and industrial interests are vying to develop crops that can survive drought, floods and shifting pest regimes. Increasingly, they look for solutions in an unlikely place: the gene pools of wild plants. Crop wild relatives (CWR) – species closely related to crops, including their ancestors – offer breeders the allure of retracing the domestication bottleneck, infusing genomes of modern crops with ‘lost’ genetic variety. Yet wild relatives also confront threats from climate change, urbanization and expansion of industrial agri-food. Thus, CWR, seen as both salvational and threatened, have become an international conservation and food-security priority. It is my contention that, in their common project to harness wild-relative potential, conservation and breeding science are co-evolving to extend seed commodity relations into new spheres. I examine enclosures along two fronts: first within ‘systematic CWR conservation’, where ‘in situ’ approaches, typically regarded as empowering and sustainable alternatives to ‘ex situ’, instead may support a complementary system of value extraction; second, in breeding and biotechnology research, which produces new value for CWR while profoundly shaping upstream conservation priorities. An important finding is that although today’s ‘ex situ-centric’ complementarity favors dispossession, an ‘in situ-centric’ approach could foster democratic renewal of biocultural diversity. 相似文献

Governments at all levels buy mission‐critical goods and services whose attributes and performance requirements are hard to define and produce. Many governments—and the public managers who lead them—lack experience and knowledge about how to contract for complex products. The contract management counsel provided to public managers is thin. Missing is a conceptual managerial framework to guide purchasing the complex products that are often so critical to public organizations' core missions. Drawing on perspectives from across the social sciences, the framework presented in this article provides guidance on how managers can harness the upsides of complex contracting while avoiding its pitfalls. The framework helps identify conditions that increase the likelihood of positive outcomes for the purchasing government and the vendor—the win‐win. To illustrate the framework, the article provides examples of successful and failed acquisitions for complex products such as transportation projects, social service systems, and information technology systems. 相似文献

Although the relation between family relationships and the timing of sexual debut has been the focus of many studies, research
on mediating factors is scarce. This study examines whether low levels of family cohesion result in an earlier onset of romantic
and sexual experiences, and whether the link between family cohesion and an early sexual debut is mediated by early romantic
initiation. A longitudinal sample of 314 adolescent girls and 222 boys, aged 12–17 at Wave 1, completed questionnaires at
three measurement points with three year intervals. The results showed that sexual debut followed romantic initiation for
77% of the participants. For early adolescent females (aged 12–14), high levels of family cohesion resulted in a later sexual
debut and this association was fully mediated by a delay of romantic initiation. Among boys and older girls, timing of romantic
initiation did not mediate the link between family cohesion and timing of sexual initiation. Early adolescent girls who have
negative relationships with their parents turn to romantic relationships for intimacy and support, which subsequently provide
the opportunity for an early sexual debut. Low levels of family cohesion thus primarily precipitate romantic initiation and
sexual initiation appears to be secondary to this process among girls in this age group. 相似文献

This article draws on a biographical case study of the first women to obtain doctorates in economics at the University of Berlin between 1900 and 1925. Their educational opportunities and experiences were linked to the networks that tied the women’s and social reform movements, as well as to the disciplinary differentiation of the German social sciences and the development of social work. These connections allowed them to exploit particular employment niches before and during the First World War, but the foundations of the expertise upon which women economists could call did not hold in the new political and institutional context of the Weimar Republic. What these early graduates patched together in response reveals a complex of opportunities and limitations presented by their simultaneous exploitation of essentialist and expertise‐based arguments. 相似文献
