Three Natufian base camps in Israel—el-Wad, Hayonim and Eynan—have nearby basalt sources, but K/Ar ages indicate that their inhabitants obtained implements, made of Miocene-Pliocene and Quaternary basalts, further afield. The nearest locations, in which raw material sources representing the whole range of dated basalts occur within a relatively restricted area, are to be found east of the Jordan Valley, suggesting movement of the material some 100 km to el-Wad, 60 km to Hayonim and 20 km to Eynan. The exact nature of these longdistance contacts and the underlying social and economic systems and mechanisms are yet to be determined.  相似文献

This paper tests for possible effects of the implementation of the British National Health Service (NHS) upon the health of the British population. Although analysis does reveal statistically significant improvements in Great Britain's infant mortality rate concurrent with the implementation of the NHS, a comparison with other western European nations reveals similar improvements simultaneously with the British policy intervention. Thus, we cannot conclude that the NHS had a significant effect upon British health. A more important result, however, is the demonstration of the utility of both the Box-Jenkins techniques and, in conjunction, the nonequivalent control group quasi-experimental design as important tools for performing policy evaluations.  相似文献

Few archaeological sites can claim a more celebrated position than Megiddo, the Armageddon of biblical revelation. Guardian to a strategic pass on the ancient land bridge that traverses the region, it has long been known that Megiddo played a prominent role in the emergence of the Iron Age nation‐states of biblical fame. Given its pivotal location, Megiddo provides an ideal opportunity to examine the experience of a community that found itself at the centre of these developments. The archaeological and textual evidence indicates a community that enjoyed extensive contact with an array of culturally distinct sociopolitical groups emerging in its hinterland. To further explore the nature and extent of this interaction, an assemblage of 86 ceramic sherds was analysed by instrumental neutron activation analysis (INAA). This paper presents the results of this analysis, together with an evaluation of potential geochemical and archaeological interconnections. Based on this comparative analysis, implications are drawn regarding Megiddo's role in the changing cultural and political landscape of this formative period in the history of the region.  相似文献

Plasters and mortars from Lardirago Castle (Pavia, northern Italy) have been characterized by means of petrographical and chemical analyses in order to achieve technical and historical evidence of material production. The study focused on the oldest nucleus of the structure, where hidden plastered masonry has been discovered recently. Textural and compositional data of the binder and the aggregate fractions were collected by means of optical microscopy and electron microscopy coupled with microanalysis. These data permit the identification of building materials with similar technical and compositional characteristics, which can be related to different building phases.  相似文献

The phenomenon of inner-city revitalization has recently stimulated attention in a number of advanced nations. The argument is extended to the Canadian city through a discussion of the housing market in Vancouver's inner neighbourhoods. The problem of the erosion of modestly priced accommodation in the inner city is emphasized, suggesting that present trends may reinstitute a zone of privilege adjacent to the downtown core, substantially modifying the residential morphology and land use models inherited from the industrial city. Le phénomène de la revivification de l' intérieur urbain, depuis peu, attire l'attention dans certains pays avancés. L'exposé en vient au case de la ville canadienne par une discussion du marché de l'habitation des quartiers centraux de Vancouver. Le problème de l'érosion du logement de prix abordable est mis en relief. Les tendances actuelles se mblent évoluer vers le rétablissement d'une zone privilégiée adjacente au centre ville, modifiant sensiblement la morphologie résidentielle et les modéles d'utilisation du sol hérités de la ville industrielle.  相似文献

In March 2013, a group of German, Nepalese, and Swiss historians, Indologists, and an architectural historian gathered for a workshop in Nepal to develop a new approach to the understanding of South Asian historiography, especially the Nepalese chronicles from the nineteenth century. The outcome is the present collaboratively written article. It is argued that, in the past, the analysis of South Asian historiography has been preoccupied by arguments based on an understanding of history that highlights facts and events. A transcultural and multidisciplinary approach, however, would overcome the common dichotomies of factuality and fictionality, history and myth, or evidence and truth. Recognizing the specificity of South Asian historiography, the article develops an approach to bridge asymmetries and entanglements in the academic use of the past in a way that also opens up a new perspective on Western historiography. By analyzing the religious, spatial, literary, and historical, and contemporary or context‐related aspects of a nineteenth‐century chronicle and by using “fieldwork” as a methodological tool for studying historiography, it is proposed to understand the framing of time and the making of sequences and historical periods as an open process that results in the constant and synchronic creation of chronological spaces.  相似文献

ABSTRACT At the regional level in-migrant and indigenous workers are likely to have different income levels and consumption propensities. The effects that these differences have upon a local economy are explored within an extended input-output modeling framework. Two iterative input-output models, due to Miernyk et al. and Blackwell, are recast as systems of simultaneous equations and are shown to produce identical results. A detailed analysis is made of model structure and a method is outlined for the decomposition of income multipliers. Empirical versions of the two models, for Boulder and Cork, are reconstructed with data from the original studies and are used to make comparisons of the two local economies.  相似文献
