Radiocarbon Chronology of the Siberian Paleolithic 总被引:2,自引:0,他引:2
We have compiled 462 C-14 determinations for 120 Paleolithic and Mesolithic sites from Siberia and the Russian Far East. The Mousterian sites are dated to ca. 46,000–28,500 BP. The Middle–Upper Paleolithic transition dates to ca. 43,300–28,500 BP. Although there are a few earlier sites, most of the Upper Paleolithic sites are dated to the time interval between ca. 34,000 BP and 10,000 BP. The earlier Upper Paleolithic stage is characterized by macroblade technology and is radiocarbon-dated to ca. 34,000–20,000 BP. The earliest microblade technology occurs in the late stage of the Upper Paleolithic, dated to ca. 23,000–20,000 BP, but the majority of microblade sites is dated to ca. 20,000–11,000 BP. The Final Paleolithic (Mesolithic) sites date to ca. 12,000–6000 BP. At ca. 13,000–11,000 BP, the earliest Neolithic appeared in both the Russian Far East (Amur River basin) and the Transbaikal. The Paleolithic–Neolithic transition occurred ca. 13,000–6000 BP. 相似文献

Abstract. In the text some questions about the genesis of radical nationalism on the former Yugoslav territory are discussed. The author's main thesis is that what happened during the outburst of nationalism was an alteration in the status of national identification, particularly in its relation to ‘supranational’ Yugoslav identification; that is, the eruption of radical nationalism was the result of reorganisation within an identification matrix. This thesis is first clarified by a short historical survey of the status of national identification before the outburst of nationalism, and secondly by an analysis of the main changes in the identification matrix during the outbreak of nationalism. Additionally, some of the main characteristics of political socialisation in the Yugoslav socialist state (especially the function of the value ‘brotherhood and unity’), as well as the possibility for future non-conflictual relations between the nations of former socialist Yugoslavia are discussed. 相似文献

ABSTRACT. In Wren (1994) I find that industrial subsidies have significantly greater employment effects in small firms, and interpret this as arising from the poorer access that these firms have to private funds. Holden and Swales (1996) criticize this interpretation, arguing that financial constraints typically limit the effectiveness of subsidies. In this paper I show that their results arise from the particular properties of the homogeneous production function. More generally, I show that the effectiveness of assistance increases with the marginal cost of private funds and is greater in those firms facing financial constraints. As such, differential access to private funds can explain the greater effectiveness of assistance found in small firms. 相似文献

ABSTRACT. Total cleared area in a von Thünen land-use model drives an atmosphere externality which depresses agricultural productivity uniformly throughout the region. Exogenous events that encourage clearance and use of a larger cultivated area (output price or population increase) exacerbate the externality. Imposition of a simple, corrective tax on land rents does not reverse these patterns but does mitigate the increase in the externality and leaves cultivators with higher incomes than they would obtain without the tax. We examine an optimal tax on land rents, designed to maximize the social value of land rents in the region, and an output tax. 相似文献

In skeletons excavated from Woodland sites, copper and barium levels are found to have been contaminated by influx from the soil environment. Electron microprobe scans for both elements show build-up along the outer surface of femur cross sections. Elemental levels for Cu and Ba are lower in the femur or fibula than in the more porous rib. The distribution of Cu in the immediately surrounding soil is highly anisotropic. These observations indicate that Cu and Ba should not be used for dietary inferences about ancient populations without independent evidence that diagenesis is not important. 相似文献
