Since Professor Sp. Marinatos linked the eruption of Thera with the destruction of Cretan sites, difficulties have been met in reconciling the dates of the two incidents which, based on pottery, were c. 1520 BC and 1450 BC, respectively, giving a “time gap” of 70 years. None of the mechanisms proposed for the Cretan site destructions-tsunamis, ash fallout, earthquakes, civil disturbances or invasion can be reconciled with the magnitude of the simultaneous site destructions. Therefore, an alternative theory is proposed that the Cretan holocaust was caused by “nuées ardentes” emanating from Thera. It is postulated that these were released through a “split” in the cone wall, of limited area, generating a high velocity jet of tephra fluidized in a red hot gas stream. Such a jet is immensely destructive and lethal, causing death by pulmonary oedema. The shape (like a blowtorch) and course of the ash fallout, as measured by deep sea cores, shows that these nuées ardentes passed over the eastern part of Crete, causing severe destruction and depopulation. The geological record confirms that tephra deposits from such Peléan eruptions have travelled for 160km, or more, and that normally the main eruption is preceded by a preliminary one of lesser intensity, with a time gap ranging from 51 to 203 years. Settlements on or at the base of the volcano would have been abandoned at the time of the preliminary eruption/earthquakes (c. 1520 BC). A time gap of 70 years would be reasonable, fitting with the Cretan catastrophe around 1450 BC. In the meantime, reoccupation had commenced, but was terminated by the final eruption. Apparently, Knossos on the periphery of the blast was severely damaged by fire (possibly again in LM II) and rebuilt, being finally destroyed in late LM IIIB. During this time span some “blurring” of pottery dating may be attributed to recovery and use of pottery “heirlooms”. The nuée ardente theory explains the simultaneous destruction of sites by fire and blast, the Cretan depopulation, as well as the time gap. In general 14C results confirm the dates proposed. So far tephra deposits have not been identified on Crete itself, but grains of it have been found at Pyrgos. It is suggested that cores from lake bottoms should be examined for the area, and that Cretan soil samples should be checked for tephra particles by employing the flotation technique, used in mining, for separating them. 相似文献

We document the geographic concentration patterns of Russian manufacturing using detailed microgeographic data. About 80% of three-digit industries are significantly agglomerated, and a similar share of three-digit industry pairs is significantly coagglomerated. Industry pairs with stronger buyer–supplier links—as measured using Russian input–output tables—tend to be slightly more coagglomerated. This result is robust to instrumental variable estimation using either Canadian or US instruments. Using Canadian ad valorem transport costs as a proxy for transport costs in Russia, we further find that industries with higher transport costs are more dispersed, and industry pairs with higher transport costs are less coagglomerated. 相似文献

信息权力的出现源于信息资本主义的深刻变革。本文认为,信息权力是指行为体运用自身掌握的信息资源对其它行为体施加影响的能力。信息资源包括信息内容、信息基础设施、信息和通信技术,行为体对这三者的综合运用形成信息生产力、信息获取力、信息控制力等不同维度的信息权力。信息资源的分布组合定义了信息权力的基本格局,而行为体基于其道德取向、实际利益的互动关系包括协作、对抗等,对已有的信息权力格局进行再定义。展望地理学对于信息权力的研究,可运用于地缘政治、城市网络与地方建构等,信息权力空间格局的演化、信息权力要素及其作用机制、不同行为体之间的信息权力博弈等将成为今后信息权力研究的新课题。 相似文献

This article examines conflicts concerning urban space, focusing on relationships between autonomous space and neoliberal urbanism through the empirical example of the cultural centre AKC Metelkova Mesto in Ljubljana, Slovenia. Through a thematic discourse analysis of activist interviews and collective statements by activist groups connected to Metelkova, research questions concern how urban conflict is constructed from the vantage point of autonomous space; what role autonomous space is assigned in relation to such conflict; and how tensions and antagonisms within the autonomous space can be understood. Theoretically we engage in a reinterpretation of the notion of heterotopia in conjunction with critical urban theory, analysing Metelkova as an autonomous heterotopia. Further, we argue that theoretisations of autonomous spaces need to consider experiences from Central and Eastern Europe, in which the conditions are shaped and constructed in conjunction with particular configurations of abruptly implemented neoliberal governance and the rise of the authoritarianism. 相似文献

中国城市旅游集散中心模式的对比分析——兼论旅游集散中心的功能与形成机制 总被引:5,自引:0,他引:5
中国的大型城市为了解决巨量散客出游的问题,由上海率先建立了“旅游集散中心”的散客旅游服务模式,目前已经被证明适用于中国现行体制下的特大型城市,符合城市旅游发展之需。国内其它许多城市也跟着建设了名为“旅游集散中心”的机构,但是仔细比较可以发现,这些机构虽然表面名称一致,在体制和运行机制上却存在较大差异,实际运行效果也很是不同。文章比较分析了上海、杭州、成都、北京以及其它若干城市的旅游集散中心在体制、机制与运行效果上的异同点,并探讨了旅游集散中心的本质特征与形成机制,强调了它的准公共产品属性。 相似文献

In an era of globalisation the 'global' is very much implicated in the 'local'. Local events like conflicts therefore need to be understood in the context of the dynamics of globalisation. This paper argues that neoliberal globalisation undergoes a thorough grounding in accordance with the pre-existing socio-cultural and economic specificities of places, which impact upon inter-community alienation and conflict. Using four case studies from a Hindu–Muslim conflict in a neoliberalising city, Ahmedabad, India, this paper illustrates how open market policies are implicated in local industrial restructuring and urban renewal that simultaneously utilise place-specific ethnocentrism to exclude and fragment the poor. 相似文献

Searching for the Promised Land: Examining Dr Martin Luther King's Concept of the Beloved Community1
Joshua F.J. Inwood 《对极》2009,41(3):487-508
Abstract: 4 April 2008 marked the 40th anniversary of Dr King's assassination in Memphis, Tennessee. Since his murder we have seen Dr King's message of social justice, the growing threat of militarism, the threat the USA's burgeoning empire posed, and his goal of ending injustice boiled down to a few words spoken in Washington DC when he declared his dream to see his children grow up in a society free of race prejudice. This paper engages with Dr King's work and presents a more geographically sophisticated understanding of King's legacy than the oft repeated Washington speech. Through an analysis of Dr King's concept of the Beloved Community, I argue that Dr King's work stems from the experiences of the Black Atlantic world. Consequently, we should see Dr King's social theory as part of a larger anti‐colonial struggle which sought to integrate African American and Western notions of community, which holds contemporary importance as a counterpoint to current neoliberal conceptions of community. 相似文献

Coalitions have always played an advocacy role in policymaking, but they are increasingly regarded as a form of community capacity that can be harnessed to civic ends. As explored in this study of urban school reform in Oakland, California, this civic view of coalitions confronts a tension between the cohesiveness and the inclusiveness of coalitions. Coalitions unified around cohesive goals and beliefs are often narrowly based, which can encourage the formation of rival coalitions. By contrast, reform coalitions that build broad-based support across the community may have difficulty developing coherent reform strategies. Using a social network analysis of key stakeholders to analyze the challenges of building civic capacity in Oakland, we find that the school district's recent reform experience more closely resembles an advocacy coalition than a broad civic coalition. The article then explores strategies for developing a broad civic coalition by expanding the existing advocacy coalition. We use the network analysis to identify opportunities for brokerage across individuals, institutions, and issues. 相似文献

Abstract: This article is concerned with the politics of inclusion. It analyzes the institutionalization of participatory citizenship as the formation of regimes of "civic governmentality". Through the study of key civil society organizations such as SPARC and Hezbollah, it studies three dimensions of civic governmentality: an infrastructure of populist mediation; technologies of governing (for example, knowledge production); and norms of self-rule (for example, concepts of civility and civicness). However, such regimes of civic governmentality operate within frontiers of urban renewal and indeed often facilitate and manage such types of development. The article examines the limits and contradictions of the politics of inclusion in the context of the bourgeois city and also studies radical forms of citizenship that emerge to challenge these limits. 相似文献
