Cluster analysis of randomly sampled soil materials on the basis of their detailed particle size properties shows that the materials form statistical clusterings–called here ‘textural groups’. Soil materials comprising the textural groups are also clustered spatially, and are hence mappable. Textural groups with geomorphic significance are recognizable at two hierarchical levels in the Q-mode cluster dendrograms, and indicate that the spatial variability of soil particle size can be envisaged as existing at two levels of scale. All textural groups demonstrate a consistent relationship to five landform types of crests, hillslopes, pediments, flood plain and infilled channels. At the higher hierarchical level, two major groups divide valley-side slopes at the pediment head into two topographically and genetically distinct zones–one of crests and hillslopes, and the other occupying pediments and flood plain system. At the lower hierarchical level, soil materials from crests, hillslopes and infilled channels form largely separate groups, while the pediment and flood plain deposits combine to form a further group. Boundaries between groups at both higher and lower hierarchical levels represent major and minor discontinuities respectively in the downslope variation in soil particle size properties.  相似文献

ABSTRACT. The study of minorities is central to research in ethnicity and nationalism. But there are cases where the precise nature of the minority is not easy to determine. One view of Southern Irish Protestants is that in the decades after independence they transformed themselves (or were transformed) from British nationals to Irish nationals or, alternatively, from a British ethnic to an Irish religious minority. This paper argues that treating the (past) British dimension of Irish Protestant identity as ethnic or national misconceives it and overlooks the historically deep Irish context of Protestant identity. One consequence of this is the neglect of the specifically Irish roots of residual tensions in Catholic–Protestant relationships. The themes of the paper are exemplified with case material drawn from research on Protestants and Catholics in rural West Cork.  相似文献

“Theory” is all the rage among religious studies scholars generally. But with the tiniest number of exceptions, this is not true in American religious history. American history in general has not proven receptive to theoretically oriented scholarship, and American religious history may epitomize this aversion; most histories of religion in America follow the classic forms of narrative history. yet the study of religion in modern urban America illustrates the desirability and perhaps even the inevitability of rethinking both religion and modernity. Without rethinking modernity, especially the assumption of its secularity, our histories cannot explain or even adequately describe the remarkable resilience of religion in so seemingly secular a place as Manhattan. And without rethinking religion we may not be able to comprehend its ability to thrive and to embrace uncertainty and spiritual pluralism alike.  相似文献

This article examines the justification for the existence of nuclear weapons. For many they were the saviour that brought an implacable foe to its knees in 1945 and held another at bay for nearly a half‐century. The belief that superior technology brought strategic advantage, that greater numbers meant strong security, and that the end of containment justified whatever means were necessary to achieve them prevailed. The author was an adherent to this point of view for several years. But these beliefs, Lee Butler contents, have proved dangerous. They account for the most severe risks and most extravagant costs of the US–Soviet confrontation; they intensified and prolonged an already acute ideological animosity; and they continue to entail enormous costs and expose humankind to unconscionable dangers. The author discusses how his convictions have evolved, and concludes that we have no greater responsibility than to bring the nuclear era to a close.  相似文献
