Castilianization of Catalonia is often thought to be most intensive in the most accessible and central areas. With the help of Geographical Information Systems and characteristics of the road and railway networks, centrality scores for urban municipalities and municipalities near the city of Barcelona have been calculated. The analysis of language characteristics does not show any significant relationship of accessibility on the one hand and the distribution of language characteristics on the other. Instead, Catalonia's linguistic geography is strongly linked with massive in-migration of Castilian-speaking minorities. This conclusion may even be valid in a retrospective sense.  相似文献

A successful outcome of the 2010 Nuclear Non-Proliferation Treaty (NPT) Review Conference is widely seen as vital if the NPT is to continue to play an important role in preventing nuclear proliferation. Focusing on the concept of trust, this article offers a novel perspective on the treaty and its future prospects. Too often dismissed as impossible or dangerous in international politics, trust has received little attention from both academics and practitioners. This article challenges this predominant view by making a case that the NPT establishes and embodies a series of trusting relationships between states. Trusting relationships are analysed as a way in which states relate to each other, taking into account both interests as well as promises. It does not make the case that once such relationships are established they will remain constant, but rather that trusting relationships are dynamic. They can be strengthened or weakened depending on the choices of actors. The article shows how trusting relationships have underpinned the NPT from its beginning and charts their evolution by reference to three key sets of relationships. These are, first, the relationships between the recognized nuclear weapon powers and the non-nuclear weapon states; second, those among the recognized nuclear weapon states; and third, those between the NPT signatories and those states remaining outside of the treaty. For each set of relationships the problems and issues that have eroded trust are outlined and the steps that might lead to the overcoming of these strains and the strengthening of the trusting relationships are discussed. By understanding the NPT through the prism of trust, the article sheds new light on both the achievements of the treaty as well as its potential fragility. At the same time, such an analysis opens up the directions of policy crucial to strengthening the treaty at the Review Conference and beyond.  相似文献

Summary. A number of settlements and other traces of occupation have been identified in the mountainous areas near to tin and copper deposits in the Erzgebirge, and some of them excavated. The newly collected evidence seems to suggest that many small sources of metals, both tin and copper, were exploited, the former metal by washing from the river and creek beds. Though these sources were more modest than the British and Spanish tin supply, they seem to have served the Bohemian and Saxon Bronze Age cultures well.  相似文献

Representations of ships, sailors and seafarers are common in many ancient societies. They were carved, drawn or painted on a great variety of raw materials – stone, wood, metal, textiles and pottery – and can be found in settings such as caves, tombs or royal palaces. Their presence at these sites raises the possibility that these images of maritime life have symbolic or ritual connotations. This paper presents examples of representations of Phoenician and Punic ships from the first millennium BC, in an attempt to understand the role of both their creators and their audiences. These images are subsequently analysed in more detail, focusing on their technical features and their historical contexts. This paper concludes with a consideration of the social and religious aspects of ancient Mediterranean navigation.  相似文献
