The European structural and investment funds (ESIF) constitute the prime instrument of EU regional policy. We study the ESIF's effectiveness in terms of fostering intra‐EU income convergence through investment support to lagging regions. Our empirical results for the period 1997–2007 indicate that the ESIF's contribution to income growth is insignificant or even negative for several peripheral EU regions. We argue that the negative link between funding and regional growth is mainly attributable to spatial spillovers. While the latter may reflect the intensified competition for scarce production factors among highly funded regions in geographical proximity, we also discuss the role played by structural backwardness in a macro‐regional context to explain this sobering result. As such, we show that negative funding effects significantly correlate with lower levels of regional institutional quality. Taken together, our findings indicate that unintended distortionary effects restrain EU regional policy from working effectively to foster income convergence. 相似文献

This study investigated the relationship between chronological age and pulp tooth area ratio (PTR) in maxillary central teeth using cone‐beam computed tomography (CBCT) images in the Turkish population. The sample consisted of CBCT images of 120 male and female subjects between 14 and 75 years old. The PTR of the maxillary central teeth was calculated using inVivo 5 software (Anatomage, San Jose, CA). Data were analyzed with independent t‐test and Pearson's rank correlation test. There was a significant negative correlation between chronological age and PTR (r = ?0.615). The results showed that the PTR of maxillary central teeth is a reliable method for age estimation in the Turkish population. 相似文献

Ethnicity coding means that threat‐based views of ethnic minority members spur opposition to specific welfare programmes. To advance knowledge of the influence of political parties on ethnicity coding, we apply a dynamic approach. Longitudinal analyses show that: a) because right‐wing political parties persistently frame state pensions as benefitting native majority members, a perceived ethnic threat increases support for this welfare scheme, and b) a perceived ethnic threat reduces support for social assistance when right‐wing political parties frame it as favouring immigrants. Extending these findings, we show that opposition to immigrant welfare rights prompts electoral realignment, as left‐wing voters increasingly switch to right‐wing parties. More generally, political parties are capable of stimulating opposition to parts of the welfare state, including electoral mobilization against immigrant welfare rights. We utilize unusually rich mass‐level survey data from Denmark, covering a 25‐year period (1990?2015). The broader implications of our findings for theories of ethnicity coding, political elite persuasion, and welfare state development are discussed in the conclusion. 相似文献

This article provides an encompassing analysis of how economic crises affect social regulation. The analysis is based on an innovative dataset that covers policy output changes in 13 European countries over a period of 34 years (1980–2013) in the areas of pensions, unemployment, and child benefits. By performing a negative binomial regression analysis, we show that economic crises do matter for social policymaking. Our main empirical finding is that crises impinge on social regulation by opening a window of opportunity that facilitates the dismantling of social policy standards. Yet crisis‐induced policy dismantling is restricted to adjustments based on existing policy instruments. We do not find significant variation in policymaking patterns across different macroeconomic conditions for the more structural elements of social policy portfolios, such as the envisaged social policy targets or the policy instruments applied. This suggests that economic crises do not lead to a profound transformation of the welfare state but to austerity. 相似文献

ABSTRACTReading Félix Guattari’s concept of ecology through feminist accounts of care and solidarity, and vice versa, in this article, we propose the concept of feminist technoecology as a speculative mode of thinking with borders. Rather than considering borders as lines on maps or primarily as physical arrangements, we argue that feminist technoecology allows for an understanding of borders as multispecies matters of care where cuts that matter are enacted, and precisely therefore calls for transversal solidarity and care that goes beyond the human. Turning to two stories revolving around the naturalisation of borders, bodies, and territories, we demonstrate that a technoecological take on borders not only fundamentally questions an a-priori distinction between technology, ecology, geology, politics, bodies, and a more-than-human world, but also foregrounds different modes of attentiveness with regard to questions of care, nativity, and mattering. 相似文献
