日本史学中“近世”一词,出现于江户时代,原是当时人自指,即“最近时代”之义。明治维新之后,“近世”所指时代仍为江户时代,其涵义则与近代对立,以至于被归入中世"第二次世界大战后史学的发展使近世得以脱离中世范畴,被视为一个独立时代概念。而在地域研究和近代化论兴起的背景下,近世与当代的关系得到强调,近世的内涵又出现了“最近时代”的意味。“近世”概念出现至今,经历了变义、独立而回归的过程" 相似文献

We develop the concept of a policy bubble to capture the notion of long‐term overinvestment in a policy. In sketching the relation of policy bubbles to economic bubbles, we describe how these two concepts have similar origins but different trajectories because they are filtered by different institutions. We examine in some detail three likely instances of ongoing policy bubbles: crime policy, school reform (charter schools and private education vouchers), and the contracting and privatization of public services. We show how these cases differ from the housing bubble of 1997–2007, how they differ from each other, and the extent to which they can be considered policy bubbles. Last, we suggest this concept can help unify the policy process literature with the practice of policy evaluation and outline testable hypotheses for future research. 相似文献

Abstract. In this paper, we suggest a framework that allows testing simultaneously for temporal heterogeneity, spatial heterogeneity, and spatial autocorrelation in β‐convergence models. Based on a sample of 145 European regions over the 1980–1999 period, we estimate a Seemingly Unrelated Regression Model with spatial regimes and spatial autocorrelation for two sub‐periods: 1980–1989 and 1989–1999. The assumption of temporal independence between the two periods is rejected, and the estimation results point to the presence of spatial error autocorrelation in both sub‐periods and spatial instability in the second sub‐period, indicating the formation of a convergence club between the peripheral regions of the European Union. 相似文献

The issue of site function rarely has been a main focus in the study of Portuguese Upper Paleolithic. This fact may be related to a lack of interest in this research area. More likely, however, it is due to the fact that there are relatively few Paleolithic sites with data that allow a serious study of site function. At Picareiro Cave, central Portugal, there are various data sets from level F/G dated to the latter Magdalenian that are adequate for this type of research. These are habitat structures, lithic artifacts, macro- and mesofauna, as well as 3D location of all artifacts and fauna larger than 1 cm. Based on the interpretation of the analytical results of each data set, it is possible to reconstruct site function of this particular level of Picareiro Cave. The morphology of one of the hearths, being very large in size, with the base prepared and a pavement surrounding it, as well as the condition and diversity of fauna, indicates that it was used for processing the meat of rabbits, red deer, and wild boar, probably through smoking and grilling. All of the evidence from the different types of data (lithic artifacts, habitat structures, use of space, and fauna) indicate that Layers F/G of Picareiro Cave are the result of a specific task, that of processing animal carcasses of rabbits, red deer, and wild boar. 相似文献

We explore diet and mobility in Middle Archaic Florida using human burials and faunal remains from the Harris Creek archaeological site (8Vo24) on Tick Island. We conducted stable carbon and oxygen isotopic (δ13C, δ18O) analyses of 50 human enamel samples and strontium isotopic (87Sr/86Sr) analysis of a subset of 10. Most individuals (46/50) subsisted on local freshwater and terrestrial resources, with relatively depleted δ13C values (C3) and δ18O values matching those of central and north Florida water resources within the St. Johns River valley. Eight of 10 burials have local, within valley 87Sr/86Sr values. Two human burials yield marine δ13C and 87Sr/86Sr values, which we interpret as evidence for across valley movement from the coast. Another two individuals show depleted δ18O values, likely obtained from northern rivers. We also identified potential food resources and non-local foods from the Harris Creek faunal assemblage. We found six species with estuarine and marine habitat preferences; two of which, whelk and quahog, indicate that people of Harris Creek traveled to or traded with coastal areas. 相似文献
