Metropolitan governance arrangements and their policy purposes have been a matter of debate among researchers and practitioners around the globe. While we may trace three broad schools of metropolitan governance – reform school, public choice theory and new regionalism – with each still having its proponents, we are interested to learn whether there are assumptions on metropolitan governance that have today become general knowledge among urban political elites. By investigating the attitudes and perceptions of city mayors across Europe, we show that functional multipurpose governance bodies are indeed more generally associated with equitable service distribution, whereas the preconditions for cost-efficiency and sustainable development are more equivocally placed at different modes of governance. Moreover, we show that a perceived general lack of problem-solving capacities does not automatically translate into pressures for metropolitan reform, but it is only in combination with a general disaffection with the governance structures currently in place.  相似文献

Abstract

This Special Issue explores macroeconomic effects of aid from various perspectives through a blend of studies, both conceptual and empirical in nature. The overall aim is to enhance the understanding of the macroeconomic dimensions of aid in the policy and research communities, and to inspire further innovative work in this important area. This opening article provides a scene setting summary of five generations of aid research, with a particular focus on how the JDS has contributed to this literature, and ends with an overview of the papers included in this Issue.  相似文献

This article seeks to explain the combined political effects of international sanctions against Iran and Tehran's domestic responses on the power structure of the targeted regime. It contends that although sanctions have contributed to elite infighting in Iran, they have not weakened the targeted regime. The Iranian leadership's modified reading of the imposed sanctions from targeted United Nations, US and European Union (EU) nonproliferation sanctions as an opportunity to develop indigenous nuclear capabilities to the perception of comprehensive and coordinated US and EU sanctions as regime change efforts marked a critical juncture. Tehran's adjusted responses to these sanctions, shaped by the interplay between Supreme Leader Ayatollah Ali Khamenei and President Mahmud Ahmadinejad, affected Iran's balance of power to the detriment of the outgoing president and his faction. This impact sheds a light on the workings of a targeted hybrid regime under intensive sanction pressure.  相似文献

Within the current debates about Euro‐constitutionalism, the conventional options are either to defend a vision of the European Union (EU) which separates global economic law from national sovereignty, and thus relies on the legitimizing powers of free markets, or to regard the legitimation problem (at least under current conditions) as beyond solution: This view argues that any further progress towards an ever closer Union would inevitably increase the legitimation deficit and that therefore the capacity for political action of the nation state should be protected or restored. This paper seeks to break the stranglehold of the, as is argued, false dichotomy (global markets vs. national democracy), and it argues that an extension of democracy beyond the nation state is possible.  相似文献

Stamp marks are used as a unique identification for a range of items, but these can be erased for criminal activities. Erased marks can sometimes be recovered by etching or magnetic means. The present study looked at the application of Fry's reagent to recover erased marks from steel. The investigation also demonstrated that Fry's reagent can deteriorate on storing and will require a longer etching time. The effect of different applied forces of stamping was investigated, and the depth of the underlying deformation was determined by etching after varying degrees of metal removal. The amount of metal needing to be removed depends on the force applied to the die. Metal removal also affects the time needed for recovery. The underlying structural change remains as a hidden identification mark, and could potentially be used by manufacturers as an unseen identifier. A model for the underlying deformation is proposed.  相似文献

Intergroup Prejudice in Multiethnic Settings   总被引:7,自引:0,他引:7  
This article examines how out-group perceptions among Asian Americans, blacks, Latinos, and whites vary with the racial composition of their surroundings. Previous research on the contextual determinants of racial attitudes offers mixed expectations: some studies indicate that larger percentages of proximate out-groups generate intergroup conflict and hostility while others suggest that such environments promote interracial contact and understanding. As most of this research has been directed at black-white relations, the applicability of these theories to a multiethnic context remains unclear. Using data that merge the 1992–1994 Multi-City Study of Urban Inequality and 1990 Census, we find that in neighborhood contexts, interethnic propinquity corresponds with lower levels of out-group prejudice and competition, although intergroup hostility is higher in metropolitan areas with greater minority populations. Further tests suggest that these results do not occur from individual self-selection; rather ethnic spatial and social isolation bolster negative out-group perceptions. These findings suggest the value of residential integration for alleviating ethnic antagonism .  相似文献

In a previous study, a survey‐based analysis of pathologist diagnoses of patterned injury in which participants were asked makes diagnoses from photographs in the absence of history or context. The level of consensus was low. A follow‐up survey was created to ask those who responded to the first survey why they answered as they did or why they were unsure of their answers. The most common reason for lack of consensus was that the lesion was nonspecific. Responses invoking ambiguity were more common than those that indicated a confident difference in diagnosis. There were differences between demographic groups, with age and experience being most prominent. These findings suggest that differences in image interpretation do not generally reflect firm differences in diagnosis as much as differing ways of dealing with ambiguity in the absence of history and context. A third survey will study the effect of the addition of contextual information.  相似文献
