The strontium isotope ratio (87Sr/86Sr) is used in archaeological studies to identify major events of population movement in prehistory such as migration, conquest, and inter-marriage. This study shows that the strontium isotope method can be expanded to identify more subtle shifts in prehistoric human mobility. 87Sr/86Sr isotope ratios were analyzed in dental enamel from human and faunal specimens from the Late Neolithic and Copper Age on the Great Hungarian Plain. The archaeological record indicates that several aspects of life changed during the transition from the Late Neolithic to the Copper Age (ca. 4500 BC) in Hungary; evidence for increased interaction over a wide geographical area, less resource pooling and the use of secondary products has been used to support the idea that local populations became more mobile, perhaps due to the adoption of an agro-pastoral economy. Results from this study identify a change in the range of strontium isotope values from the Late Neolithic to the Copper Age from a very narrow range of values to a much broader range of values, which suggests that changes in how land and resources were utilized on the Great Hungarian Plain affected incorporation of strontium into the skeletal system. This study indicates that the strontium isotope ratio is a valuable tool for identifying more subtle changes in prehistoric behavior such as a shift to a more pastoral economy. 相似文献

Extraordinarily well-preserved organic remains from mortuary and settlement sites, including mummified bodies, are scattered along the outer, oasis-laden rim of the Tarim Basin in Xinjiang Province, China, ranging in date from about 1400 BC to the late first millennium BC. Specimens of textile finds from Chärchän, dated at about 1000 BC were selected for dye analysis using newly developed protocols employing high performance liquid chromatography with spectrophotometric and mass spectrometric detection. A single blue (from an indigo plant), a red (from madder, a Rubia species) and two yellow dyes were detected, although the exact plant source for none of them could be identified with certainty. This research offers new insights in the interpretation of textile finds from prehistoric Xinjiang, and more generally, of early Bronze Age Eurasia. 相似文献

Xeropolis is a tell site on the island of Euboea, Greece just to the east of the village of Lefkandi, and was occupied from the Early Bronze Age to the Early Iron Age. Excavations in recent years have provided an opportunity to investigate site formation processes using geoarchaeological and geochemical techniques. Sediments derived from the tell on the southern side have been lost by coastal erosion whilst those on the north mantle the flanking slope. Of particular interest is a homogeneous and unstratified deposit of over 2 m which overlies the archaeology near the southern perimeter of the summit area. The soil structure as evident in thin sections indicates a high degree of bioturbation, probably stimulated by recent manuring and cultivation. The implication is that tillage erosion has had a major impact on the morphology as well as on the surface soils of the tell. Despite such reworking and redeposition of near surface materials, it is still possible from multi-element analysis to identify the geochemical distinctiveness of six archaeological contexts (pit, house, plaster floor, alley, road and yard); pits and floors have high loadings of all elements except Pb; in contrast pits and floors have the lowest elemental concentrations. 相似文献

Neo-liberal ideas have resulted in a planning practice characterized by an informal phase in which early agreements are reached in closed negotiations between municipal planners and private developers. This challenges norms of legitimacy and accountability found in traditional democratic theories, as well as deliberative planning and network governance theories. Input-based legitimacy may be weakened by the lack of participation as well as by asymmetry in resources available for participation (voice). The representative democracy's (vote) responsiveness to the electorate may be weakened due to the lack of knowledge of the views of those affected, early lock-in to agreements and weak meta-governance due to the lack of adherence to overall plans. Throughput legitimacy is reduced by the lack of transparency, and thus accountability, in the informal phase. Output legitimacy might justify the privileged position of developers if tangible results are achieved. However, lack of participation weakens the quality and long-term lastingness of decisions, and lack of deliberation weakens the acceptability of justifications for those burdened by the decisions. We argue that two different types of reforms are necessary to increase the input legitimacy of planning practices: representative democracy reforms that strengthen the role of politicians and reforms that strengthen the direct participation of stakeholders in planning. 相似文献

This paper discusses the out of school routines of a group of ‘literature-devoted’ children of the city of Madrid (Spain). The children and families were recruited for the study at a library, a children's bookstore and a puppet show in a park. Participants provided information on their weekly routines through several procedures: surveys, photographs of their daily lives, interviews based on the photographs and interviews with parents. We develop a spatially based model that allows us to identify four styles of activity in children's out of school lives: homebound children, non-scheduled children, outdoor and scheduled children, and fully scheduled children. Our results suggest that there is significant diversity in the ways in which children's after-school time is organized, even within a middle-class and socially homogeneous sample as the one in this study. Also, the range of activities our participants engage in seems to contradict current portraits of Western urban children's lives as constrained. 相似文献
