Diffuse idiopathic skeletal hyperostosis (DISH) is common condition and its prevalence increases markedly with age. This paper describes the pathology and aetiology of the condition; DISH seems to be related to obesity and type II diabetes and is probably a multisystem hormonal disorder. DISH occurs frequently in human skeletal remains, particularly in those recovered from monastic sites. Evidence is presented to confirm this association and the causes are discussed. We also present criteria for the diagnosis of DISH in human remains, which we suggest would permit valid inter‐study comparisons. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

Set within the context of the global food supply system, this paper examines the growing trade in fresh horticultural produce between Kenya and the UK. The links between UK retailers and Kenyan producers are investigated using the concept of the marketing chain. Two major chains are identified - wholesale and supermarket – and, whilst having no direct investment in Kenya, it is the supermarkets who control production there, through intermediaries who ensure that standards of quality and presentation are met. Importers play a crucial role in facilitating this trade, acting as a vital link between farmers and exporters in Kenya and supermarkets in the UK. The need for quality and traceability dictates that contractual arrangements are made predominantly with large-scale farms using productivist farming methods. The irony is that it is post-productivist demands by 'new consumers' in the UK that are encouraging these productivist horticultural systems in Kenya.  相似文献

The ways the British planning system fosters racial disadvantage and the initiatives taken by local authorities to address such bias have been subject to a number of studies over the last 17 years. This body of research has revealed isolated examples of progressive professional practice within a general pattern of inaction and ignorance. This paper looks at how the needs of ethnic minorities have been accommodated by the planning system in Northern Ireland that has a very different institutional and political context than other parts of the UK. The nature of 'race' relations in Northern Ireland is examined and the concept of 'policy processes' is used to explain why ethnic minorities in the region face similar difficulties to those in Britain. The influence of the political and cultural context is shown to play a key role in framing the policy processes that shape patterns of discrimination. The paper suggests that a full understanding of this context is required if multiculturalism is to be fully accommodated by planning in Europe.  相似文献

Three cases of meningioma are described from a single site in Hertfordshire yielding a total of 83 male and 84 female burials. The lesions were present in the parietal and frontal bones, and were bilateral in one case. All presented as a defect in the inner table of the skull and were supplied by a large aberrant artery; in two instances the lesion had eroded completely through the skull but no hyperostosis was present. The unusually high prevalence of this tumour is discussed in the light of other palaeopathological findings. © 1998 John Wiley & Sons, Ltd.  相似文献

Abstract

Two German maps of southern Africa, one official, the other private, came to the attention of the British government in the 1890s and raised questions of boundary delineation. In both instances, they provoked a response—diplomatic dispute and internal policy decision—but in neither case did the maps do more. They actively initiated contention but were passive devices thereafter.  相似文献

This article analyses South Africa's current postapartheid transition in the light of earlier transformations of its social and economic order. The first of these prior transformations is the abolition of slavery and the shift to liberal capitalism, which took place in the early nineteenth century. The second is the rapid industrialization of the late nineteenth and early twentieth centuries. Each of these transformations, as well as the current transition, is explained as being partly the outcome of a broad shift in capitalist practice, innovated in the metropoles of the global economy. Due to South Africa's situation within global economic networks, each of these shifts, at different times, raised the threat of a dislocation in South Africa's prevailing social order. However, each prior transformation and, it will be argued, the current transition, has been 'managed' by established elites so as to ensure minimal change to the overall distribution of privilege. This conservative 'management' of shifts in capitalist practice, it is suggested, has been facilitated through South African elites' historic engagement with cultural discourses circulating across a global terrain. In this article then, contemporary South Africa is located within both material and discursive networks which have historically influenced the country's distribution of privilege.  相似文献
