To date, most obsidian sourcing studies in the Andes have concentrated on the highlands and Titicaca Basin of far southern Peru and northern Bolivia. Toward achieving a more complete understanding of the region, this paper offers new data on the long-term prehistoric obsidian procurement and consumption patterns in the Andahuaylas region of the south-central Peruvian highlands. Obsidian sourcing data from Andahuaylas are particularly interesting since the area is centrally located among several important regional obsidian sources. A total of 94 obsidian samples from a range of sites of different temporal periods were chemically analyzed using portable X-ray fluorescence (PXRF), as well as laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). The results demonstrate a number of interesting trends, the first of which is the long-term importance of the Potreropampa obsidian source to populations of the Andahuaylas region from at least the early Formative period (∼2500 BCE). Secondly, the results indicate that procurement strategies by local populations in Andahuaylas were primarily reliant on nearby (<150 km) obsidian sources. Finally, the paucity of more distant, yet widely exchanged, high quality obsidian (i.e., Chivay, Alca) confirm that as a region, Andahuaylas was more heavily connected economically (and likely culturally) with local areas to the south (Apurímac) and to the west (Ayacucho).  相似文献

Many attributes of present day soils can only be explained by reference to land management in the historic past. This is particularly well expressed in the plaggen soils which occur extensively on the north European plain. These deepened soils owe their dominant characteristics to the application from the 12th century of turf materials, often impregnated with dung. Similar deepening of soils can result from the disposal of urban waste. This paper discusses the results of soil research focused on a small Scottish town (Nairn). A soil survey revealed topsoils of over 1 m overlying fluvioglacial sands and gravels; such deepening is explained by the use of town waste on the burgh's arable lands from at least the 17th century up until the mid-19th century when an integrated sewerage system was installed. Micromorphological study of this deepened topsoil revealed the presence of many small black carbonaceous particles. Oxygen:carbon ratios were calculated from microprobe results as a means of confirming the carbonaceous nature of these particles. Soil phosphorus was primarily concentrated on the perimeter of these particles. The high quality of present day soils on the edge of the town is explained by the disposal of waste material, which included much carbonised material. This paper is the first to highlight the importance and potential of examining the gradation in soils from urban to rural contexts.  相似文献

The intersections between the concepts of space, place and resistance have recently received increasing attention from geographers dedicated to the study of social movements. Space and place are not merely seen as providing a physical background for mobilisations but as mutually constitutive of social movement agency. Yet, critics of theoretical frameworks drawn up by geographers have often rightly pointed to the lack of convincing empirical evidence presented in their support.This paper addresses these critiques by offering a theoretically informed and empirically grounded account of recent mobilisations by the social movement of black communities in the Pacific coast region of Colombia. Drawing on both the objective aspects of place and the subjective feelings that are derived from living in a place, I will show how these mechanisms have impacted on the specific spatial organising forms adopted by black communities. In particular, I will propose the concept of ‘aquatic space’ as a set of spatialised social relationships among Afro-Colombians, and show how these concrete everyday geographies have been drawn upon by black communities in the establishment of community councils along river basins.The paper argues that to make a strong point for more spatially sensitive analyses of social movements, geographers have to sustain their theoretical frameworks with concrete empirical data that not only illustrate spatial processes at play, but also convincingly demonstrate their very embeddedness in social practice. I thus argue for a strong consideration of ethnographies as a privileged research methodology to flesh out the geographies of social movements.  相似文献

The key concerns in work on the politics of the Middle East in the past decade have been economic and political liberalization/democratization (or the absence thereof) and security, both domestic and international, along with a continued focus on the Arab‐Israeli conflict. There has been an increasing recognition that these issues are strongly interrelated. Europe cannot avoid concerns over economic and political stability in the region affecting its own interests. Together with economic reasons for engagement with the region, this has brought about a desire to see economic and political reform take place. The Euro‐Mediter‐ranean Partnership Initiative (EMPI) is one result of this. The background against which these policies, concerns and hopes are evolving is ‘globalization’, both of the discourse of ‘democracy’ and in the growing hold of liberal market economics internationally. Recent research on the politics and political economy of the region, and on EMPI, however, shows that a combination of political‐economic and related political‐cultural factors, along with the Arab‐Israeli conflict, continue to hamper political and economic reform in the Middle East, and that European policy as currently conceived is unlikely to affect this greatly. Yet such recent work also shows that aspects of globalization are changing the environment in which Middle Eastern regimes are having to function, while at the same time offering civil society new tools. Middle Eastern societies do, to varying extents, possess the necessary ‘spaces’ and traditions for human ‘agency’ to escape the constraints of domestic and international ‘structures’ and evolve new political cultures‐including democratic ones. Existing judicial or legislative institutions may acquire volition of their own and reinforce this process. There is nothing in ‘Islam’ that necessarily obstructs such possibilities. And supposedly ’obsolete‘ monarchies might yet be among the most successful types of regime in coping with such change.  相似文献
