A summary is given of the geological, faunal and archaeological information obtained during excavations in the Stanton Harcourt Channel Deposits from 1990 to 1995. The channel deposits underlie the ‘cold-climate’ Stanton Harcourt Gravel Member of the Summertown– Radley Terrace Formation. The Channel sediments are attributed to Oxygen Isotope Stage 7, when the Thames was undergoing down-dip migration and eroding the Weymouth Member of the Oxford Clay (Upper Jurassic), the contemporary Jurassic (Corallian) escarpment being near to Stanton Harcourt at that time. Abundant large vertebrate remains have been recovered, mainly from the base of the Channel deposits, where a cobble and boulder bed rests on thin silt or sand horizons or in scour hollows in the clay bedrock. Smaller bones occur throughout the deposits, which are mainly poorly sorted gravels, but especially at erosive horizons. Several palaeolithic artefacts have been found in the same contexts; many of the bones and some of the artefacts appear not to have been transported far. Although the artefacts cannot be linked directly with the bones, a study of them adds to our knowledge of the Middle Pleistocene human settlement of the Upper Thames Valley. It is of interest that mammoth is abundant as part of the interglacial faunal assemblage, and the significance of this is discussed. The environment clearly included substantial areas of open grassland, although there was also some forest in the vicinity. Evidence appears to be accumulating for important faunal and floral differences between particular interglacial events during the British Middle and Late Pleistocene. 相似文献

Post-colonial critiques of development reveal the neo-colonial potential of the development project, embedded in the imbalances of power in relations between West and East, First World and Third World. One of the core responses to the challenge of such a critique has been to turn to new participatory approaches that privilege local knowledges, locally defined needs and priorities, above the vagaries of aid agencies or the 'expertise' of development professionals. In this paper I argue that such a shift in development discourse and method has had a significant impact on the discursive practices of professionalism and professional responsibility. Drawing on ethnographic research with development professionals in northern Thailand, I argue that participation has emerged as a new orthodoxy among development professionals who seek to identify themselves as ethical and moral agents of an emancipatory development project. The rise of such orthodoxy has had clear impacts in terms of fostering the emergence of local organization and advocacy groups. At the same time, however, this paper considers how a 'pro-local' orthodoxy may also be having dis-enabling effects for the very project of emancipation that professionals wish to carry out. 相似文献
