George Woodcock was anarchism's most influential historian and an important public intellectual in Canada. This article focuses on his engagement with Canadian nationalism in the 1960s and 1970s. It argues that a ‘philosophical anarchism’ was at the heart of his intellectual project, and this informed his reading of Canadian cultural development and subsequent political challenge to Pierre Elliott Trudeau's civic nationalism. Woodcock decoupled the concepts of ‘nation’ and ‘state’ in order to develop a radically different model for Canada—the ‘anti-nation’—defined by regionalism, federalism and direct democracy. His reading of Canada's cultural history supporting this position was therefore part of a strategy to repurpose nationalist rhetoric towards anti-state ends. 相似文献

Cooling centres provide respite, safety, and social support during extreme heat events for populations that do not have the resources to own or operate in-home air conditioning. The objective of this study was to measure the spatial accessibility of cooling centres and analyze the associations between cooling centre access and marginalization in Montreal, Toronto, and Vancouver, Canada. The potential spatial accessibility of cooling centres within a 15-minute walk was measured at the dissemination area scale using the two-step floating catchment area method. A two-stage modelling approach was used to analyze the associations between cooling centre access and marginalization. Approximately 62%, 58%, and 54% of the populations in Montreal, Toronto, and Vancouver had access to at least one cooling centre. In Montreal and Vancouver, high marginalization areas were more likely to have cooling centre access than low marginalization areas. Of the areas with cooling centre access, smaller access scores were observed in areas with high residential instability. Approximately one-fifth of the areas in each city had no cooling centre access and high marginalization, and may be considered for future cooling centres or programs that improve accessibility to existing centres. 相似文献

Solution strategies are presented to address three potential problems in the empirical derivation of fragility functions from empirical data using the maximum likelihood method. The first strategy addresses the case of fragility curves that cross, the second strategy incorporates demand uncertainty in fragility derivation from post-earthquake reconnaissance data, and the third strategy provides a framework for the resolution of conflict between empirical data and expert opinions. The advantages and disadvantages of the proposed solution strategies are discussed and their use is demonstrated by way of suitable illustrative examples. 相似文献

It is the era of decolonisation in central Africa: angry mobs in the streets; authorities struggling to contain agitation by communists and other subversives; reports of Africans strangled to death or dragged behind cars by European settlers; whites arming themselves. One might presume these scenes of disorder and abuse took place during the Congo crisis from 1960 to 1965, when events appeared to spin out of control in central Africa. In fact, they occurred during the years after the Second World War, when Belgians seemed to have affairs well in hand in their central African colony. The Congo crisis is almost always viewed in sharp contrast to the peaceful era that preceded it—as if the lifting of Belgian rule unleashed chaos—and the relative stability post-1965 that came with the Mobutu dictatorship. There is broad agreement that Congo’s independence was a fiasco, with the former colonial ruler, Belgium, largely to blame. This essay argues that the Belgian authorities were not as in control as has been believed. Historians have known for years now that things were not as rosy as they might have seemed at the time, in the years leading up to independence in 1960, but recently available archival documents reveal the situation was even more fluid than previously thought. Bula Matari was not as far-reaching as believed, and many controls signalled a nervousness inherent in the late colonial state more than they did its strength. Reports by administrators reveal a lack of domination in the 1950s and underlying tensions in the colony, even conflicts. The public impression that Belgians had affairs well in hand is due in part to post-Second World War propaganda depicting an idyllic Congo. Belgians wanted to build support for colonialism, bolster their authority, forestall foreign interference and combat their own anxieties. Images produced persuaded many that the Congo was more peaceful than it was. The shock at independence ought to be attributed less to events unfolding as of June 1960 and more to the impressions of tranquillity projected by the authorities beforehand. 相似文献
