Through an analysis of 100 asylum decisions and 10 interviews with 20 asylum officers at the Swedish Migration Agency this article reveals two intricate processes through which children’s rights are displaced in the Swedish asylum process; by overlooking children’s individual claims for asylum through a circle of neglect, and negating children’s best interests. The article demonstrates how the balancing act between migration control on one hand and children’s rights on the other hand plays out in the asylum process, which results in a double displacement; the children are not adult enough to be addressed as asylum seekers and not children enough to deserve qualification as bearer of children’s rights. An in-depth analysis of everyday practices at institutions applying children’s rights is essential both to understand the reproduction of discrepancies between rights on paper and rights in practice, and to explore the potential of rights to disrupt oppressive vehicles of power.  相似文献

Punctuated equilibrium theory (PET) suggests that the policy process is characterized by long periods of incremental change and short periods of punctuated change. The impetus for the latter is usually a focusing event that breaks open policy monopolies, allowing for major changes in legislative decision making. While a burgeoning body of literature, a shortcoming in the PET literature is that it has yet to explain why focusing events and subsequent breakdowns in policy monopolies sometimes fail to result in punctuated policy. We integrate theories on cultural change with punctuated equilibrium to explain why focusing events do not always result in the dramatic policy changes that we might expect. Specifically, we use the context of national energy policy and the lexical database, Google Ngram Viewer, to trace punctuating energy‐related events and the occurrence or lack thereof subsequent policy change from 1952 to 2000.  相似文献

The complexity of decentralized regulatory contexts can threaten program fidelity, particularly if it results in divergence between program goals and the intents of regulatory inspectors. This paper investigates how inspectors negotiate the conflicting demands of a decentralized program by examining how they perceive their regulatory roles – the primary responsibilities that inspectors ascribe to their functions and the entities to which they feel responsible – and how these role orientations are related to inspectors' attitudes toward the use of discretion. The study findings indicate that in the decentralized administration of United States organic food regulations, inspectors experience multiple, and sometimes conflicting, role orientations. The presence of multiple role orientations, however, does not seem to affect how inspectors approach their responsibilities. The combined strengths of quantitative and qualitative data are leveraged to offer explanations for the study findings and identify avenues for future research.  相似文献

About half of the nations that experience civil war eventually relapse into renewed conflict within a few years after the original war ends. This observation has motivated a stream of research into the factors that affect the risk of peace failure in the aftermath of civil war. While the outcome of the previous civil war—for example, military victory versus peace agreement—structures the post-war environment in ways that affect the risk of peace failure, the capacity of the post-war state to enact and implement policies that affect the incentives for and capacity of groups to undertake armed violence as a means of advancing their interests should also affect the risks of peace failure. Using Geddes’ categories of nondemocratic regime types, we will present a theory of how different regime types have varying capacities to repress and/or implement accommodative policies that affect the risk of peace failure. We test propositions derived from this theory with a series of event history models. Our findings suggest that while peace agreements significantly increase the duration of post-civil war peace, peace agreements involving some types of nondemocratic regimes actually increase the risk of post-civil war peace failure.  相似文献

In federal systems, both state governments and firms have incentives to strategically locate polluting facilities where the environmental and health consequences will be borne as much as possible by residents of other jurisdictions. We analyze air polluter location in the United States using a spatial point pattern model, which models where events occur in latitude and longitude. Our analyses indicate that major air polluters are significantly more likely to be located near a state's downwind border than a control group of other industrial facilities, results that are robust to a wide variety of model specifications and measurement strategies. This effect is particularly pronounced for facilities with toxic air emissions. The observed pattern of polluter location varies systematically across states and time in ways that suggest it is responsive to public policy at both the national and state levels.  相似文献

The study of political conflict in legislatures is fundamental to understanding the nature of governance, but also difficult because of changes in membership and the issues addressed over time. Focusing on the enduring issue of civil rights in the United States since Reconstruction, we show that using current methods and measures to characterize elite ideological disagreements makes it hard to interpret or reconcile the conflicts with historical understandings because of their failure to adequately account for the policies being voted upon and the consequences of the iterative lawmaking process. Incorporating information about the policies being voted upon provides a starkly different portrait of elite conflict—not only are contemporary parties relatively less divided than is commonly thought, but the conflict occurs in a smaller, and more liberal, portion of the policy space. These findings have important implications for a broad range of work that uses elite actions to compare political conflict/polarization across time.  相似文献
