In recent years the urban question in the European Union has been a matter of deep focus and intensive debate, contributing to the European Community environmental, spatial and sustainability policies approach, however not entirely reflected in the current version of the 6th European Environmental Action Programme. The POLIS programme, initiated in Portugal at the time of the last Portuguese Presidency of the European Union (January–June 2000), illustrates the Portuguese urban environmental policy approach in that period, in response to contemporary trends and priorities regarding the improvement of urban life and governance. This article describes the POLIS programme, its current status and how it meets current challenges. The expetience acquired so far with the POLIS programme may be useful in the broader context of the discussion of an European urban policy.  相似文献

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献

There were from the very beginning two ways of conceptualising the events of 1956 in Hungary, labelling it as a revolution or a national uprising. There also emerged a third way of conceptual definition when what occurred in 1956 was named an anti-totalitarian movement. From the theoretical perspective of Begriffsgeschichte the Hungarian events of 1956 cannot simply be assumed under the notion of ‘revolution’, the term first applied to what took place in France in 1789, since it was not the kind of a forceful collective effort leading to an unknown future. The notion of ‘revolutio’ works better to describe the analytical meaning of the Hungarian anti-Soviet and anti-Communist disturbance. The reason has been that the main thrust of the Hungarian situation in 1956 was similar to the seventeenth-century English and the eighteenth-century American ‘revolutions’, to return definitively to a point of departure by regaining some of the formerly lost social and political liberties.  相似文献

This paper examines the spatial distribution of the Internet in the European regions. To achieve this aim, our analysis combines a set of non-parametric techniques proposed in the context of the economic growth literature, with various spatial econometric instruments. The results reveal that regional disparities in Internet adoption are greater than territorial inequalities in gross domestic product (GDP) per capita. In addition, our findings show that the distribution under consideration is characterized by the presence of positive spatial dependence, which implies that physically adjacent regions register a similar degree of Internet adoption. Finally, the analysis carried out allows us to assess the role played by variables such as GDP per capita, unemployment rate, stock of human capital and population density, in explaining the spatial distribution of the Internet in the European Union.  相似文献

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.  相似文献

This paper discusses the impact of the conference ‘Las Olvidadas: Gender and Women's History in Post‐Revolutionary Mexico’ that took place at Yale University in May 2001, into my own work on women's political mobilisations. It points out from where I departed and how it changed my perspective from women's history to gender history by focusing on women workers in the tortilla industry, a union cacicazgo (political bossism), civic culture, narratives, cultural memory and female political trajectories after the granting of women's suffrage in 1953 in Jalisco.  相似文献
