Evolving retail landscapes: power retail in Canada   总被引:1,自引:1,他引:0  
During the last fifteen years the Canadian retail landscape has been transformed by the growth and clustering of big box retailers into a range of 'power retail' developments. This has brought new retailers into Canada (predominantly U.S. retailers) with different business strategies that have lead to different consumer behaviour. The power retail phenomenon encompasses all aspects of the retail offer (price, product, service, etc.) and is not simply about the size of stores. These developments have led to new types of commercial clusters—power centres and power nodes—that have challenged both planning policy and the existing retail hierarchy across Canada, and conversely, provided substantial scope for retailers and developers to exploit market opportunities. The article discusses the alternate definitions of power retail, estimates the magnitude of this activity, and examines the spatial pattern and preferences of these new retail locations. The development of power retail is tracked across Canada and regional variations examined. The key trends in power retail growth are identified and potential directions for future development suggested.  相似文献

There is a disharmonious resonance between the lifecycle of the human immunodeficiency virus and that of its human host. In heavily affected countries, many people live long enough to reproduce and then die, leaving behind numerous orphans. This process has implications that we do not understand. While some foresee social disorder arising from legions of poorly socialized and unruly children grown to adulthood, the evidence is far from clear. These arguments and the evidence are reviewed in this article, particularly in relation to the links between premature death and electoral processes in southern Africa.  相似文献

Traditionally divided on security matters, France and Britain broke new ground when they signed the 1998 Saint‐Malo agreement, promising to collaborate on defence and security, and pledging to cooperate bilaterally and in a ‘bi‐multi’ fashion on Africa. This Anglo‐French collaboration is the focus of this article, which begins by setting out the lack of UK–French security cooperation in Africa from the colonial to the early post‐Cold War era. It then shows how there has been a degree of institutionalization of Anglo‐French relations, alongside greater cooperation in terms of ESDP missions and the training of African peacekeepers. Next, this study explains the recent evolution of UK–French security relations in terms of neo‐classical realist theory. Finally, it assesses the likelihood of closer Anglo‐French security collaboration in the future.  相似文献

Contemporary and later commentators emphasized the Supreme Court's forceful affirmation of its own authority in Cooper v. Aaron (1958). The case was the Court's first significant test of states' rights opposition denying that Brown v. Board of Education (1954) (Brown I) and the Brown II (1955) decree permitting gradual implementation were legitimate constitutional law. Indeed, following the Court's announcement of Cooper v. Aaron in September 1958, Arkansas Governor Orval Faubus and his followers closed the very same Little Rock schools the Supreme Court had ordered desegregated. Black students' rights did not prevail until summer 1959. In Arkansas and elsewhere, defiance initially triumphed over the Supreme Court's self‐assertive power. 1  相似文献

A method is described which can be used to calculate the number of tumours that might be expected to occur in a group of skeletons. The method of calculation is based on published data that relate to the frequency with which various primary tumours metastasize to bone and on the number of deaths from malignant disease at the turn of the century. The method has been applied to one archaeological site and the results indicate that the number of tumours found—although very small—is within the limits suggested by the model.  相似文献
