The argument of this paper is that a deeper appreciation of the nature of the power relationships between firms and the circuits of power that bind them together is key to understanding how clusters function — including how they might emerge and how they might decline. We begin to develop a conceptualization that allows us to generate a deeper understanding of the processes that enable the production and reproduction of enterprise clusters under some combinations of circumstances but not others. The sections of the paper explore: (1) concepts of power and circuits of power including their spatialities; (2) the temporarily stabilized relationships which occur in clusters of economic activity; (3) the openness and permeability of clusters as a way of understanding conditions that foster cluster growth; (4) a tentative integration of concepts. From this reading of the concepts of clustering and power we draw the conclusion that clusters are, at any particular point in time, temporary and transient conjunctures of interfirm relationships. They depend on specific circumstances in 'time–space' and, because of their very transience and specificity, those conditions might be very difficult if not impossible to create through the blunt instruments of policy.  相似文献

More and more teams around the globe are gaining ethical clearance to perform face transplant surgery. The operation is a highly experimental medical treatment and patients who are otherwise healthy are dying as a consequence of submitting themselves to the operation. This article is concerned with the quiet deaths and ethical slippages that are emerging in this new medical terrain. It suggests that an examination of the relationship between nationalism and medical advancement is necessary to understand this slippage, because inter alia the surgery has been afforded national significance.  相似文献

ABSTRACT

China’s Scenic and Historic Interest Areas are a major contributor to the State’s World Heritage lexicon. However, understanding of their values has led to confusion internationally and in China, not least with controversy over China’s latest promotion of the Natural Protected Areas System. This paper discusses values of China’s Scenic and Historic Interest Areas from the cultural landscape perspective through an in-depth case study of Lushan. A theoretical framework for recognising values of China’s Scenic and Historic Interest Areas has been set up and tested at Lushan, including exploring stakeholders’ understanding of its values as a world heritage site by using semi-structured interviews and questionnaires. The findings reveal that Lushan clearly represents cultural values inextricably associated with Scenic and Historic Interest Areas, and also need for supplementary advice on its Outstanding Universal Value (OUV). It suggests that the ideology driving management of China’s Scenic and Historic Interest Areas as national parks or natural parks focusing mainly on objective nature-related conservation without regard to the traditional Chinese philosophy of the culture-nature binary will adversely affect China’s Scenic and Historic Interest Areas as cultural landscapes and their community values.  相似文献

This essay takes a new look at the destruction and the rebuilding of the house of commons during the 1940s. It argues that behind the home front bravado of the Palace of Westminster steadfastly enduring the blitz lay secret plans for rehousing MPs away from aerial bombardment, contingency scenarios that were then updated after 1945 in the event of attack on London by atomic weapons. The essay also suggests that threats to the security of parliament, together with the necessity to rebuild the Commons, were turned by the coalition government into an opportunity to refashion parliamentary politics in such a way that the two‐party system was restored, along the traditional lines of government and opposition that had become blurred since 1931.  相似文献
