Europeans constituted their post‐Second World War political identities in terms shaped by the Cold War but matters took an unexpected turn when the events of 1989/91 required acknowledgement of the hitherto largely unremarked existence of the project of the European Union. The question of the identity of Europe/Europeans moved into mainstream debate: how can the variety of 'national pasts' be reconciled, how might ideas of Europe/Europeans fit within the range of identities affirmed by Europeans, and can the project present a clear image within the international community? The European Union is the only game in town for Europeans but it is also deficient; reform is made more difficult by the struggle to define the post bloc world: reform for what becomes the issue ‐ upgraded US ally, loose free trade area or federal polity? These are awkward questions but the continent is recovering from the catastrophe of its twentieth century and one can feel optimistic for the future. 相似文献

We investigate the informal bilateral transgovernmental relations between equivalent ministries of EU member states during the preparation of the Intergovernmental Conference 1996. Starting point of this analysis is the hypothesis of a growing importance of transnational and transgovernmental relations as a cause and a result of European integration. Whereas these proclaimed tendencies have been extensively researched with regard to economic interdependencies and transnational relations of societal actors, networks of the administrative and bureaucratic elites have been rather neglected. Applying diverse concepts of network analysis, we identify the hitherto latent informal network structures of the governments. The overall configuration can be described as a mixture of a centre-periphery structure and cohesive blocks. The gradual center-periphery structure consists of a “triumvirate” of the powerful member states (Germany — France — Great Britain) and smaller states, and is characterized by a clear north-south dimension. The costs of informal coordination are mainly borne by the large member states as well as by “brokers” (Austria, BeNeLux, Finland, Sweden). 相似文献

Explaining differences in productive efficiency: An application to Belgian municipalities 总被引:3,自引:0,他引:3
The purpose of this paper is to measure and explain variations in productive efficiency of municipal governments in Belgium. Technical efficiency is evaluated using a non-parametric method based on the Free Disposal Hull (FDH) reference technology. We first calculate input, output, and graph Farrell efficiency measures for a cross-section of all 589 Belgian municipalities. In a second stage of the analysis we explain the calculated differences in efficiency in terms of variables related to the structural characteristics of municipalities and to the institutional environment. 相似文献

Interpreting a myocardial inflammation as causal, contributory or as of no significance at all in the cause of death can be challenging, especially in cases where other pathologic and/or medico-legal findings are also present. To further evaluate the significance of myocardial inflammation as a cause of death we performed a retrospective cohort study of forensic and clinical autopsy cases. We revised the spectrum of histological inflammatory parameters in the myocardium of 79 adult autopsy cases and related these to the reported cause of death. Myocardial slides were reviewed for the distribution and intensity of inflammatory cell infiltrations, the predominant inflammatory cell type, and the presence of inflammation-associated myocyte injury, fibrosis, edema and hemorrhage. Next, the cases were divided over three groups, based on the reported cause of death. Group 1 (n = 27) consisted of all individuals with an obvious unnatural cause of death. Group 2 (n = 29) included all individuals in which myocarditis was interpreted to be one out of more possible causes of death. Group 3 (n = 23) consisted of all individuals in which myocarditis was reported to be the only significant finding at autopsy, and no other cause of death was found. Systematic application of our histological parameters showed that only a diffuse increase of inflammatory cells could discriminate between an incidental presence of inflammation (Group 1) or a potentially significant one (Groups 2 and 3). No other histological parameter showed significant differences between the groups. Our results suggest that generally used histological parameters are often insufficient to differentiate an incidental myocarditis from a (potentially) significant one. 相似文献
