AbstractFamines in the years immediately after World War II occurred during a period of global flux, as international famine response evolved from its ambitious, early twentieth century goals toward more modest, technocratic objectives during the second half of the century. For economists, social scientists and politicians immersed in the world of emergency food aid, these were uncertain, awkward years for famine relief. Herbert Hoover’s idealistic large-scale projects of famine relief that had dominated the first three decades of the century had been proven to be expensive and of limited efficacy, but Cold War loyalties had not yet taken over as the primary logic behind large-scale humanitarian assistance projects. Ultimately, when faced with famine conditions between 1944 and 1947, states and experts balanced a call to action against pragmatism that recognized famines were also politically expedient events that could weaken rural resistance to governance and simplify wartime and postwar administration. Ultimately, both science and humanitarian concerns learned to orient themselves toward economic expediency in these awkward years. 相似文献

Home range is commonly understood to be the distance from home that children are allowed to go in the outdoor environment with the term being used within various academic disciplines. Different factors influence children's home range including traffic, age, parental fears and understandings of what it means to be a good parent. Research addressing home range over different generations has identified a context of changes in the built environment, demography and technology. This paper reports results from three generations of two families in Sheffield in the north of England and confirms a reduction in four major domains: home range, variety of outdoor spaces visited, range of activities undertaken and the number of companions. 相似文献

The contributions to the collection under review offer a wide range of treatments of ways in which German colonialism intersected with aspects of domestic German culture and politics, with particular attention to the larger global setting in which the German colonial empire existed between 1884 and 1918—or was remembered up to 1945. The review situates and critiques the contributions in interpretive contexts based on general suggestions by one of the editors, Geoff Eley. These include a context in which “colonialism” and “imperialism” are recognized as specific discursive constructions of the late nineteenth and early twentieth centuries, another in which the causal focus in interpreting colonial phenomena is placed on exchanges that constituted an accelerating globality with which available conceptual modes (including colonialism and imperialism) could not keep pace, a third that complicates the categorical distinctions usually made between types of imperial program, and a fourth that aims at replicating on a much broader and more flexible basis something like the concept of “social imperialism” that forty years ago dominated interpretations of German imperialism. The essay ends with a view of how such an interpretive framework might be constructed. 相似文献
