A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.  相似文献

Recent contributions by geographers on the relationships between states and citizens have documented the rise of rolled‐out neoliberalism. Development agendas are, it is argued, increasingly dominated by the principles of market‐driven reforms, social inequality, and a drive towards enhancing the economic competitiveness of the supply side of the economy. However, at the same time, a parallel set of discourses has emerged in the development literature which argues that it is principles of sustainable development that have, in practice, become dominant. The emphasis is, instead, on democratic empowerment, environmental conservation, and social justice. This paper examines the relationships between these ostensibly very different interpretations of contemporary development with an assessment of one of the Labour government's most ambitious planning agendas—the publication in February 2003 of the document Sustainable Communities: Building for the Future . The proposals are promoted as a "step change" in the planning system with a new emphasis on tackling shortages of housing in the South East and reviving the economy of the Thames Gateway area. The paper assesses the different ways in which such programmes can be interpreted and argues that contemporary development practices in countries such as Britain are constituted by a hybridity of approaches and rationalities and cannot be reduced to simple characterisations of rolled‐out neoliberalism or sustainable development.  相似文献

The Early Bronze Age round barrows at Irthlingborough, Northamptonshire and Gayhurst, Buckinghamshire contained remarkably large quantities of cattle (Bos taurus) remains. At Irthlingborough, at least 185 skulls with smaller numbers of mandibles, shoulder blades and pelves were found together with a small number of skeletal elements from aurochs (Bos primigenius). In contrast, the remains from Gayhurst are dominated by the limb bones from more than 300 animals. This study employed strontium isotope ratio analysis of cattle tooth enamel from 15 cattle and one aurochs to investigate the diversity of the animals' origins at both sites and provide insights into Early Bronze Age funerary practices. Although strontium results show that most of the cattle and the aurochs included in this study were consistent with local origins, one animal from each barrow was born remotely, most likely in western Britain. In addition, a second Gayhurst animal was consistent with origins in a region of chalk rather than the local Jurassic sediments.  相似文献
