The aim of this article is to present a panoramic view of the Basque Country's capacity and competence for self-government. We have analysed the historical process of industrialization, the effects of the industrial crisis and new possibilities for development of the area's own regional policy based on new institutions (Government and Provincial Councils) that emerged from administrative decentralization in Spain after 1980. In the following section, we analyse the scope of authority in EU regions. Some of the cultural and transport infrastructure projects backed by these Basque institutions are studied. These projects have had a considerable impact on the Bilbao Metropolitan Area. The changes observed in the nation state, specifically in Europe, show contradictory effects. However, they have reduced the State's sovereignty but at the same time have prompted the State to retain powers rather than transfer them to lower institutional levels. This clashes with the desire of some regions or historical nations to access greater shares of self-government, such as the case of the Basque Country.  相似文献

Aperlae was a small remote maritime city in ancient Lycia with a millennial floruit (late 4th century BC through the late 7th century AD). The harsh terrain of its hinterland forced a reliance on the Mediterranean from its founding to its demise. The Aperlites stabilized and enhanced their urban waterfronts in modest ways over the centuries, but basically they maintained and sustained their intimate relationship with the sea without elaborate docking or harbour installations. Fishing, probably a primary industry, centred on the harvest of murex trunculus , the marine mollusk from which purple dye was made. This valuable commodity appears to have been produced in Aperlae for export to Andriake, the international emporium of nearby Myra, for transshipment to textile centres throughout the Mediterranean. There, coastal traders also acquired the necessities and luxuries the city needed but did not produce. Proxy evidence, impressive archaeological features on land and under the sea, speaks to moments of prosperity for Aperlae well beyond mere subsistence. Cabotage was this secondary port's enduring lifeline.  相似文献

为了遏制共产主义在东南亚的扩张,维护美国的全球霸权,1961年5月,美国总统肯尼迪公然发动了对越南的“特种战争”。面对美国在“南大门”的战争挑衅,中国政府从无产阶级的国际主义和维护越南独立和统一的立场出发,在政治、经济、外交和军事等方面积极支持越南人民的抗美爱国斗争,并应越南党和政府的请求,开始了“援越抗美”的初步酝酿,最终确立了“美国走一步,中国走一步;美国出兵,中国也出兵”的基本原则和立场。  相似文献

The examination of isotope ratios from multiple tissues offers new life to interpretations of commingled assemblages where information regarding individual biological history has been lost. Here, life histories from a commingled sample of Byzantine monks were reconstructed using enamel and bone δ13C and δ15N values. The δ13C values suggest a diet dominated by C3 products, while the δ15N ratios indicate variable contributions of animal protein. After correcting for tissue‐specific enrichment factors, bone δ13C values were significantly enriched over enamel; this may be due to an increase in protein consumption, but could also reflect structural differences between tissues or correction factors used to compare these data.  相似文献
