After the 2008 global financial crisis, both the United States and the United Kingdom introduced austerity policies targeted at particular elements of their national budgets. The purpose of this article is to compare the nature of this retrenchment; the similarities and differences in how it was implemented; and its initial impacts on one of the expenditure areas particularly affected: affordable rental housing programs and housing support for low-income households. Using a wide range of data sources, we find evidence of political and fiscal policy analogies in the timing and forms of the initial policy choices and how these were modified in the face of economic and political pressures. There are considerable similarities both in the instruments used to reduce housing expenditures and in the early impacts on support mechanisms and recipients. However, we find different histories and trajectories of support between the two countries that suggest that the longer term differences in outcomes may be more important.  相似文献

社会保障权责配置有政府与市场和政府间之横纵两个层级。滞后的社会保障法制导致权责横纵配置的失衡-政府与市场之间配置的偏倚,政府之间配置的粗疏,这严重制约该制度功效的彰显。横向配置矫正的关键在于寻求政府责任的确定性与实现方式的多样性之间的平衡,并在发挥政府基础性作用时,倡导个人责任的回归、市场机制的引进及民间力量的渗透。纵向关系的细化要求以宪法层面原则性规定与法律层面具体性条款相结合的方式进一步规范各级政府的事权及其支出责任;从责任分担上做出更具操作性的制度安排,完善政府间社会保障支出责任分担法律机制。  相似文献

面对充满不确定性的世界。个体通常通过一种被称为归因的心理机制从不完全的信息中解释他人做出某种行为的原因。类似但更为特殊的心理机制也会发生在当一个国家的决策者需要理解另一个国家的行为以采取某种应对之策的时候。当外交决策者们在试图解释他国的行为时,他们会将哪些变量纳入他们的考虑范畴?他们对他国行为进行归因的方式是否会因情境的不同而有所变化?如果确实有所变化,那么他们在归因时将会存在哪些倾向和偏见?外交决策者通常从能力、决心、利益、意图和该国所处的战略环境五个维度来认知另一个国家行为的原因。而恐惧和族群中心主义均会作用于这五个维度,并且在不同的情境下,两者在各维度的作用方式有所差异。为了验证唐世平提出的行为归因理论,作者采用了一种特殊的内容分析技术——逐字解释文本分析——对1945-1947年间的美国外交档案进行了分析和编码,试图利用二战结束至冷战开始这段时间内美国的主要决策者对苏联行为所进行的数以百计的归因,并对上述归因理论进行经验上的探索。验证结果表明,描述性的证据分析部分支持了这一新的归因理论,但也挑战了这一理论中关于能力、决心和环境维度的部分推断。  相似文献

目的 探讨木丹颗粒对高糖环境下人血管内皮细胞核转录因子E2相关因子2(neclear factor erythroid 2-related factor 2,Nrf2)/抗氧化反应元件(antioxidant response element,ARE)信号通路及血管内皮生长因子(vascular endothelial growth factor,VEGF)的影响。方法 将健康雄性Wistar大鼠30只随机分为正常组、模型组、木丹颗粒组,每组10只,制备含药血清;将正常组含药血清加入正常糖浓度培养内皮细胞,模型组及木丹颗粒组分别加入高糖培养内皮细胞;采用RT-PCR、Western blot分别检测Nrf2、血红素氧合酶-1(heme oxygenase-1, HO-1)的mRNA及蛋白表达水平;采用ELISA法检测各组细胞上清液中VEGF含量。结果 与正常组比较,模型组Nrf2、HO-1的mRNA及蛋白表达均显著上调(P<0.05),VEGF的含量显著增加(P<0.05);与模型组比较,给药组Nrf2、HO-1的mRNA及蛋白表达水平均显著上调(P<0.05),VEGF的含量显著减少(P<0.05)。结论 〖JP2〗木丹颗粒对高糖环境下人血管内皮细胞的保护作用机制可能与上调Nrf2/ARE信号通路的表达、降低VEGF含量有关。  相似文献

ABSTRACT

The article highlights the rationale of the special issue in terms of its objectives and guiding principles. It maps different evolutions and challenges within three analytical streams (1) regarding the field of policy analysis, (2) concerning the interaction between domestic and international affairs, and (3) with regards to the transformation of European Union governance in troubled times. These three research avenues highlight how not only European governance itself has evolved in a changing world, but also how the analysis of interests, institutions, and policy-making has morphed, oftentimes transgressing disciplinary and methodological boundaries.  相似文献

In the debate on minimal media effects and their causes, methodological concerns about measurement are rarely discussed. We argue that even in state-of-the-art media-effects studies that combine measures of media messages and media use (i.e., linkage analyses), measurement error in both the media content analysis and the media use self-reports will typically lead to severely downward-biased effect estimates. We demonstrate this phenomenon using a large Monte Carlo simulation with varying parameters of the content analysis and the survey study. Results show that measurement error in the content analysis and media use variables does indeed lead to smaller effect estimates, especially when the media messages of interest are relatively rare. We discuss these findings as well as possible remedies and implications for future research.  相似文献

Why do some peace agreements end armed conflicts whereas others do not? Previous studies have primarily focused on the relation between warring parties and the provisions included in peace agreements. Prominent mediators, however, have emphasised the importance of stakeholders at various levels for the outcome of peace agreements. To match the experience of these negotiators we apply a level-of-analysis approach to examine the contextual circumstances under which peace agreements are concluded. While prominent within the causes of war literature, level-of-analysis approaches are surprisingly scant in research about conflict resolution. This article compares two Sudanese Peace Agreements: the Comprehensive Peace Agreement (2005) that ended the North–South war and led to the independence of South Sudan, and the Darfur Peace Agreement (2006) which failed to end fighting in Darfur. We find that factors at the local, national and international level explain the different outcomes of the two agreements. Hence, the two case studies illustrate the merit of employing a level-of-analysis approach to study the outcome of peace agreements. The main contribution of this article is that it presents a new theoretical framework to understand why some peace agreements terminate armed conflict whereas others do not.  相似文献

The investment approach to public service provision is now receiving considerable attention worldwide. By promoting data‐intensive assessments of baseline conditions and how government action can improve on them, the approach holds the potential to transform policy development, service implementation, and program evaluation. Recently, variations on the investment approach have been applied in Australia to explore the effectiveness of specific programs in employment training, criminal justice, and infrastructure development. This article reviews the investment approach, presents a Public Investment Checklist to guide such work, and discusses three examples. It concludes by considering the implications of investment thinking for the work of policy designers and public managers.  相似文献

Using the Princeton nuptiality index Im, we analyzed historical developments in the proportion of married women of reproductive age in Spain. We show the internal diversity in nuptiality patterns and offer an explanatory statistical model based on panel data analysis to identify the main variables influencing these changes over more than a century (1887–1991). We found that Spain has been the developed country with the greatest contrasts in its provincial nuptiality patterns (measured by Im), although this diversity has lessened over the course of time. We also found that some socioeconomic variables (the gross domestic product per capita and the percentage of population living in cities) do not have a linear relationship with female nuptiality but rather have a U shape or an inverted U shape. This may partly account for some of the controversy that has raged on this topic over the past few decades on an international level.  相似文献
