This paper explores the materiality of social power relationally through study of social interactions with artifacts. Specifically, it is argued that acquisition of an artifact instantiates social power by imposing interactions on groups taking part in that artifact's life-history activities. We introduce the “performance-preference matrix,” an analytic tool for systematically studying the effects of such acquisition events on activity groups. The use of the performance-preference matrix is illustrated through an example: the acquisition of electric-arc lights for lighthouses in the 19th century. Suggestions are offered for analyzing culture-contact situations and for handling singularized artifacts such as heirlooms and monuments.

Pronghorn (Antilocapra americana) fetal remains are sometimes recovered from archaeological contexts. Pronghorn have consistent reproductive schedules so their remains may provide information on seasonality of site occupation and number of mortality events. To investigate the reliability of fetal remains for seasonality and mortality event assessment, bone size and tooth eruption were measured in a sample of modern fetal pronghorn remains with known mortality dates. Results indicate a strong correlation between bone size and mortality date, but no significant correlation between tooth eruption level and mortality date. Fetal bone size was used to estimate a late April or early May mortality date at both the Oyster Ridge (48UT35) and Trappers Point (48SU1006) archaeological sites. The number of mortality events at Trappers Point was also investigated. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Field schools are a rite of passage for archaeologists, the first experience of what for many is the defining activity of the discipline: fieldwork. While teaching competence in practical techniques is the minimum goal of any field school, this technical training must be situated within the broader goals that drive the fieldwork. The University of Denver Archaeological Field School provides the fieldwork for the Colorado Coal Field War Archaeological Project. This project is an experiment in archaeology as political action in the present. It explores the possibility of an emancipatory archaeology through engagement with contemporary audiences and struggles. In this paper we discuss some of the ways we try to link technical training with the admittedly unusual theoretical and political goals of the project, teaching not only skills but an awareness of the responsibilities these skills should bring.  相似文献

India's and Pakistan's nuclear tests have dismayed the international community. However, they can be seen as a culmination of the deterioration of international nuclear relations that has taken place since the mid-1990s. The author examines the reasons for this deterioration which he finds in US–Russian relations, the Middle East and South Asia, in disputes over arms control objectives, and in normative and procedural dilemmas that emerged as the number of countries with nuclear weapon programmes was reduced to a 'hard core' of eight states. This discussion provides the background for an assessment of the consequences of the actions of India and Pakistan. Despite the dangers, the author stresses the opportunities that could lie ahead. If key states act positively and cooperatively, the climate and processes of nuclear arms control could be transformed.  相似文献

The INTIMATE (Integration of ice-core, marine and terrestrial records) project, the successor to the North Atlantic Seaboard Programme of International Geological Correlation Programme (IGCP-253) ‘Termination of the Pleistocene’, began in 1995 with the aim of integrating proxy climate records from around the North Atlantic during the Last Termination (18–8?ka BP). The INTIMATE remit has since expanded geographically to include the entire Atlantic basin and Australasia, while an extended temporal framework now covers the early Holocene and the Last Glacial cycle. This short paper outlines the principal achievements of the INTIMATE research community, which include the development of an event stratigraphy for the North Atlantic region; the establishment of protocols for ice–land–ocean correlation; important contributions to geochronology, most notably to tephrochronology, and to palaeoenvironmental and palaeoclimatic reconstructions; and the designation of the Greenland ice-core record as the global stratotype for the Pleistocene–Holocene boundary. Future directions of the INTIMATE programme are also briefly considered.  相似文献

Tensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand, especially during the dry season. The arguments are illustrated with a detailed examination of the Mae Uam catchment, located in Chiang Mai province, where the development of dry–season soybean cultivation appears to have tested the hydrological limit of the catchment, and even exceeded this limit in drier years. The author argues that a shift in focus from water supply to water demand has fundamentally important political implications. As long as the focus of public debate is on water supply, the regulatory focus will be on those resident in the forested upland areas that are seen as being crucial in securing downstream flows. But if the water management focus is shifted to water demand, then regulatory attention must shift to the diverse sources of demand that exist throughout the hydrological system.  相似文献
