The processes of modernisation that re-capitalised London in the post-war period can be located in both dominant and resistant movements. Many aspects of the city's discursive fabric in the 1950s and 1960s were underpinned by a similar geographical imagination. This geographical imagination was characterised by a desire to visualise and represent nature and the real afresh and can be found in modernist architecture and planning aesthetics, Pop Art, Op Art, Angry realist writing, the style of Swinging London, and the tactics of counter-cultural rebellion in the city. Acknowledged geographies of modernity and anti-modernity are therefore questionable. Similarly, the geographies of power and resistance are constituted by more than spatial tactics and moral or behavioural boundaries as they are often rendered. An approach that understands hegemonic processes in terms of geographical imaginations allows an analysis that moves beyond outward manifestations of resistance and enables an engagement with the less palpable aspects of dissent such as ideology and aesthetics. 相似文献

This paper contributes to our understandings of the geographies of science through an analysis of nineteenth–century natural history and, in particular, of the provincial natural history society. Focusing on nineteenth–century Cornwall and one of the main natural history societies operating in the county at that time – the Penzance Natural History and Antiquarian Society – it is argued that a set of key spaces were integral to the operations and outputs of such societies. The paper details the significance of the Penzance Society's museum, field sites and lecture hall as sites for communal work of local natural historians. They were also important, it is argued, in their construction of West Cornwall as a site of national natural scientific importance. Lastly, these spaces defined an agenda for regional scientific study. In particular, they promoted a taxonomic method that would transform local people into rigorous scientists and the local region into a 'book of nature'. 相似文献

‘Black Economic Empowerment’ (BEE) has been a major policy thrust of the democratic governments in South Africa since 1994 in attempting to redress the effects of apartheid. In this article, we explore the historical precedents to BEE in South Africa, review the different steps taken in promoting it, and assess some of its outcomes to date. We argue that BEE can take only limited forms because of the economic policy constraints in which it has been incorporated. Moreover, these forms have an increasingly managerial logic that further restricts what can be achieved. Short of a major shift in conceptions of — and policy for — BEE, meaningful ‘empowerment’ is unlikely to take place. 相似文献

This study characterizes the degree of calcination of lime in lime plaster samples from Teotihuacan, the capital of a regional state in prehispanic Central Mexico. Lime plaster production consists of multiple steps, from the firing of raw materials to the mixing of lime and aggregate and the final application. While previous studies have focused on the compositional variability, specifically the recipe of lime plasters and mortars, the characterization of lime itself has not been sufficiently addressed. In this study, cathodoluminescence analysis coupled with petrographic and image analyses were employed to examine the degree of calcination of lime. The results of cathodoluminescence petrography were further examined through stable carbon isotope and 14C measurements. It appeared that the results of cathodoluminescence analysis are consistent with those of other analytical methods and that there are diachronic changes in the degree of calcination of lime among lime plaster samples. This implies changes in the organization of lime production, specifically the consistency in the control of firing temperature. 相似文献

This work emphasizes the incentives for vertical integration in a spatial model. A downstream monopoly will both strategically increase its transport costs and locate inefficiently relative to its customers. This forces the upstream monopolist to lower its input price rather than permit sales to decline. The excess costs and the inefficient location lower total profit in the vertical stream generating an incentive for vertical integration. 相似文献
