Abstract We study the degree of convergence or divergence in fiscal decentralization in the European Union over the period 1995–2015 using a club convergence approach. First, we analyze non-central expenditure and revenue as percentages of GDP, of total expenditure and of total revenue. The results for the EU-15 countries indicate some clustering, with three clubs formed when using GDP and four to five when using total revenue or expenditure. Second, we study the gap between expenditure and revenue as a proxy of fiscal responsibility. This results in three and two clubs respectively, with Denmark as the divergent country with the highest gap. Finally, we analyze potential unions of clubs and transitions. We also interpret our results taking into account variables found in the literature as determinants of fiscal decentralization. These results show how European countries are quite heterogeneous in terms of fiscal federalism and decentralization, with greater convergence in fiscal responsibility than in the other magnitudes. 相似文献

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes. 相似文献

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method. 相似文献

ABSTRACTRight-wing Eurosceptic political groups gained ground in the elections for the European Parliament in May 2014. The electoral victory of right-wing Euroscepticism was accompanied by a concern that populism is (once again) spreading in Europe. Associating right-wing Eurosceptics with populism raises the question of whether critiques of populism can be directly extended to right-wing Euroscepticism. By reconstructing the right-wing Eurosceptic concept of ‘the people,’ this article demonstrates that the Eurosceptic concept of the people has a dual meaning that encompasses both a transnational and a national concept of the people. The article concludes that while Euroscepticism shares ideological features with populism, it is problematic, due to the internal structure of the promoted concept of the people and the European political environment, directly to extend recent critiques of populism to right-wing Euroscepticism. 相似文献

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers. 相似文献

ABSTRACTThis paper offers some reflections on the possible consequences of Brexit for legal education in Scotland. Scotland’s small and distinctive legal system is bolstered by devolved legislative powers and characterised by a tradition of openness to external influences. Scotland’s legal system and relatedly, its legal education system, will be poorer for Brexit. That said, this paper argues that the features and traditions of the legal system and legal higher education system in Scotland make them well placed (and perhaps better placed than those in the other domestic jurisdictions) to resist such dampening pressures and indeed to embrace EU legacies and other European and international influences. 相似文献

AbstractDoes European soft law matter? In order to answer this question, the article investigates the processes through which the European Union (EU) affects domestic politics and policies in the eHealth sector in France, Austria and Ireland. More precisely, it shows how the hardening of EU soft law creates a new rationale for the use of European instruments by domestic actors, thus expanding their strategic opportunities for policy making at the national level. Despite the empirical diversity of the cases, similar patterns of variation in Europeanisation mechanisms emerge over time, and the data show how the varying structure of European soft instruments (i.e. their degrees of ‘hardness’) accounts for these changes. This comparative analysis includes multiple process-tracing cases of eHealth public policy making in France, Austria and Ireland in which Europeanisation processes are at work. 相似文献
