Large numbers of groundstone tools have been uncovered from archaeological sites in the Early Neolithic period in China. Traditionally they are often regarded as agricultural tools for processing cereals. In this paper we report preliminary starch grain analysis of groundstone tools from Baiyinchanghan site to gain a better understanding of use of these tools in the Northeast China. We found that starch grains on these groundstone tools are most likely from Quercus sp. The result of this study indicates that many groundstone tools for the Early Neolithic period were used to process wild and domesticated plants alike.  相似文献

Copán, a major Classic Maya center in western Honduras, has been the focus of archaeological investigation for over a century. An intense period of research since 1975, involving projects and scholars from many institutions, has resulted in a comprehensive understanding of the origin, maturation, and decline of this major Maya polity.  相似文献

The analysis presented in this paper explores the similarities and differences between the services selected as priorities for funding by the Baltimore Ryan White CARE Act Title I Planning Council during the first 2 years of the program in this metropolitan area, and services perceived by HIV/AIDS service providers and people living with HIV/AIDS to be unmet needs. The data used for these analyses were collected as part of a study to assess the implementation and impact of the CARE Act legislation in the Baltimore eligible metropolitan area( EMS ). This project includes three interrelated components: (a) a case study of the legislatively mandated Planning Council, (b) a survey of providers representing HIV/AIDS service organizations, and (c) a qualitative field study of the perceptions of people living with HIV/AIDS about the service delivery system. Taken together, the data from these three sources describe the similarities and differences among these three groups involved in HIV/AIDS care in Baltimore, in terms of their perceptions of services needed by people living with HIV / AIDS. The conclusions drawn from this study can be used to strengthen needs assessments in Title I-EMAs throughout the United States.  相似文献

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.  相似文献

The paper considers the geographies of scientific knowledge produced around a pool dug at Long Gores, Hickling, Norfolk, England in 1953. Designed by ecologist and artist Marietta Pallis as a swimming pool and symbolic site, the pool also became a scientific experiment in landscape, through which Pallis pursued general ecological principles and specific theories on the landscape history and ecology of the Norfolk Broads. The digging of the pool coincided with the publication of research establishing the broads' artificial origin in medieval peat diggings. The paper begins by developing arguments concerning the cultural geographies of scientific knowledge. We then trace Pallis's presentation of the pool as equivalent for the broads in its origins and development, her discussion of the relationship between pool, marsh and North Sea, the connection between Pallis and local scientific culture, and the pool's place in a landscape of ecological succession. The paper concludes with further theoretical discussion, and reflection on the remains of Pallis and her reputation.  相似文献
