In this paper we apply earnings equations for U.K. regions over 1982–1997. We find evidence of rapid convergence across regions regarding the determinants of individual wages (i.e., regional fixed-effects, gender gaps, and returns to education and experience). In contrast, data on average regional earnings point to a worsening of U.K. regional inequalities and a rise in the North-South gap. Education accounts for most of the discrepancy between aggregate divergence and disaggregated convergence. First, London gained because its workforce became relatively more educated over the period. Second, returns to education increased nationwide, which favored the most educated regions (i.e., London). Third, returns to education were initially lower in London but they (partially) caught up with the rest of the country. Had returns to education and their distribution across U.K. regions remained stable over the period, the U.K. North-South divide would have decreased.  相似文献

Résumé  Les progrès les plus récents de la physique contemporaine, en particulier la convergence de la physique des particules et de la cosmologie en une authentique cosmogonie scientifique, avivent les enjeux philosophiques de l'entreprise scientifique, mais les rapports conflictuels entre physique et philosophie ne s'en trouvent pas apaisés; un fossé semble même en train de se creuser entre science et philosophie. L'œuvre du philosophe suisse Ferdinand Gonseth qui s'est attaché à élaborer une philosophie qui so it et qui puisse rester au ni veau de la connaissance scientifique peut fournir une aide particulièrement adéquate à ceux qui voudraient contribuer à combler ce fossé. GillesCohen-Tannoudji, né en 1938, est conseiller scientifique auprès du directeur des Sciences de la matière du Commissariat à l'énergie atomique. Il est retraité de cet organisme, dans lequel il a fait toute sa carrière comme physicien théoricien dans le domaine de la physique des particules. Actuellement, il prépare une thèse de philosophie, sous la direction de Dominique Lecourt, sur la philosophie de Ferdinand Gonseth.  相似文献

Since the early 1990s, excavations of a protohistoric lakeside settlement in the Korça basin carried out by a French–Albanian archaeological team have induced geomorphological and palynological studies about the sedimentary records of Lake Maliq. These studies allow us to distinguish a series of centennial-scale high and low lake level events between 4200 and 4000 cal BP (2899–2637 BC/2843–2416 BC) and 2600 cal BP (822–671 BC), probably due to large-scale climate changes (in the Mediterranean basin). In addition, the sediment sequence also gives evidence of a millennial-scale trend of lake level rise. It appears to be an interplay between lake level rises and falls against tectonic subsidence of the basin allowing accommodation space for sediment deposition.The variations of the lake's level and the lake's surface area influenced the development and the abandonment of the nearby lakeside settlements (like the tell of Sovjan). In order to prepare an archaeological survey around the now dried up lake, we made a 3D model of the Holocene deposit from the lake including these lake level results, geomorphological mapping, excavation data, numerous core logs, AMS 14C dating and SRTM DEM data. The GIS model allowed us to propose four palaeogeographical reconstructions of the extension of Lake Maliq: around 14,000 BP, during the Mesolithic (around 9000 BP – 8781–8542 BC), the Early/Middle Bronze Age transition (around 3800 BP – 2310–2042 BC) and the Iron Age (2600 BP – 822–671 BC). A map of the thickness of the sediments above potential archaeological layers is also proposed.  相似文献

Is world‐systems analysis of any relevance to present‐day economic flows? By using methods in line with the world‐system and dependence theories, we show that economic flows – trade and foreign direct investment – still deeply separate core and peripheries. On the one hand, through the analysis of the trade by products, we show that core countries hold on to a higher position in the international division of labour. On the other hand, by using network method, we highlight that core countries are still characterized by the intensity of their reciprocal relations while peripheral countries have few economic relations with a limited number of core countries. Moreover, the article demonstrates that this core–periphery division of the world has not lost its pertinence; it is as relevant as at the end of the sixties. In the current era of globalization, economic flows are still deeply structured by basic power relations between core and peripheries. However, the article also develops a theoretical framework to understand dynamics of the world‐system and insists on the emergence of Eastern Asia as a new core area, notably by showing the rising position of some East Asian countries in the international division of labour. We conclude by underlying the necessity to integrate world‐system and global network theoretical frameworks.  相似文献
