This paper investigates the impact of the main criterion employed by the European Commission for the allocation of the largest portion of Structural Funds, based on the threshold of the 75% of European Union (EU) average gross domestic product (GDP) per capita. We focus on the 2014–2020 programming period and on EU-15 regions to analyze if this criterion has penalized some of them, as a consequence of the 2004 EU enlargement, which has represented an exogenous shock in the allocation process, due to the economic backwardness of new member states. Through the application of Synthetic Control Methods and Difference-in-Differences estimators at different geographical scales, we show that regions that did not obtain the less developed status in both the programming period 2007–2013 and 2014–2020, but that would have obtained it in the period 2014–2020 without the 2004 EU enlargement, experienced a significantly lower GDP per capita growth between −10.5% and −5.7%. Conversely, territories that in the period 2014–2020 lost the less developed status, previously obtained in the time frame 2007–2013, were not characterized by a significantly lower economic growth, providing some evidence of the effectiveness of the safety net. 相似文献

Between the first (1952) and the third (1980) editions of psychiatry's Diagnostic and Statistical Manual of Mental Disorders, depression emerged as a specific disease category with concrete criteria. In this article, I analyze this change over time in psychiatric theory and diagnosis through an examination of medication trials and category formation. Throughout, I pay particular attention to the ways in which psychiatrists and researchers invoked science in their clinical trials and disease theories, as well as the ways in which gender played an important but largely unspoken role in the formation of a category of depression. 相似文献

The habitat preferences of fauna found at palaeontological and archaeological sites can be used to investigate ancient environments and hominin habitat preferences. Here we present a discriminant function model linking astragalus morphology to four broadly defined habitat categories (open, light cover, heavy cover, and closed) using modern bovids of known ecology. Twenty-four measurements were taken on a sample of 286 astragali from 36 extant African antelope species. These measurements were used to generate ratios reflecting shape. An 11 variable discriminant function model was developed that had high classification success rates for complete astragali. Resubstitution analysis, jackknife analysis, and the classification of several “test samples” of specimens suggest that the predictive accuracy of this model is around 87%. The total classification success rates of 87% (jackknifed) or 93% (resubstitution) are considerably higher than those derived in another study of bovid astragalus ecomorphology (67%; [DeGusta, D., Vrba, E.S., 2003. A method for inferring palaeohabitats from the functional morphology of bovid astragali. J. Archaeol. Sci. 30, 1009–1022]) that used a more limited measurement scheme and a smaller sample of bovids than the present study. Different approaches to operationalizing ecomorphic analyses are considered in order to best extract accurate palaeoenvironmental information from palaeontological and archaeological datasets. 相似文献

Paid work was important to women’s identity formation in post war Britain, especially as they returned to work after having children. The changed economic and social climate in Britain after 1945 expanded the employment and education opportunities available to some women. Class and material conditions guided women’s reasons for returning to work. They increasingly did so part-time, and in lower skilled jobs than before they had children. Understanding the self that women construct must be situated within the circumstances of women’s lives and the social and economic structures in force at that moment of returning. 相似文献
