"This paper questions the plausibility of the assumption of interregional equilibrium in recent research into migration and the valuation of amenities in the United States. It is shown that it is difficult to develop a satisfactory explanation for continuing net migration which is compatible with the equilibrium assumption, and that recent relevant research generally fails to support the idea that the U.S. economy is in equilibrium. The association of higher rent levels with in-migration is explained as a short-run phenomenon. If the spatial economy is in disequilibrium, then the valuations of amenities assuming equilibrium will be biased, being probably too low in areas of net in-migration and too high in areas of net out-migration."  相似文献

The chemical and mineralogical characterization of seven ceramic fragments produced within Tiwanaku state (c.500–1000 ce ) is reported. The instrumental techniques used included X‐ray elemental and mineralogical chemical analysis, Raman spectroscopy, and scanning and light microscopy. The results indicate there are several clay types, although they show similarities, such as the use of a plant‐based temper. The red colour of the decoration is hematite, and manganese oxides such as jacobsite are present in the black. The white colour is a mixture of gypsum and clay, and the orange is a mixture of hematite and clay. The use of colours, the quality of the clays and the temperatures reached during pottery firing point to expertise in ceramic production and to complex decision‐making processes. The multi‐elemental archaeometric approach documented here could become an important tool to shed a light on ancient ceramic technology and the internal variance of Tiwanaku pottery.  相似文献

Tel Megiddo is a major type-site for the Middle Bronze in the Levant. During this period a new burial custom appeared in which the dead were interred beneath occupied houses. This tradition is well attested in Area K at the site. Area H, near the palatial complex, revealed a monumental masonry-constructed chamber tomb. This article presents the results of residue analysis conducted on ceramic vessels placed in these tombs as burial offerings. Hundreds of intramural Middle Bronze tombs with ceramic offerings were excavated in the Levant, but this is the first time the content of the vessels is revealed.  相似文献

This study aims to provide a comprehensive examination of the evolution of regional science, a scholarly domain in the social sciences that applies analytical and quantitative approaches and methods to understand and address urban, rural, or regional problems. We conducted a bibliometric analysis of 8509 articles published in six regional science flagship journals (including the Journal of Regional Science, Annals of Regional Science, Regional Science and Urban Economics, Papers in Regional Science, Regional Science Policy and Practice, and International Regional Science Review) from 1958 to 2021. The analysis presents an objective data-driven and unprecedented visualization of the field's intellectual, social, and conceptual structure and trends from the beginning to the present. It also provides a rich portrayal of the epistemology of regional science and illuminates matters related to regional science education and training. We find that regional science has moved well beyond its origins, shifting away from a heavy focus on theory and abstraction to modeling/simulation, empirical analysis, and policy research. We also find that there has been increasing attention to “people” in regions and the spatial characteristics of social problems, and some important shifts in the regional science community itself, particularly in terms of patterns of collaboration and the geography of scholarship. The findings of this paper provide implications for future directions of research and education for regional science.  相似文献

What might anthropology offer to our understanding of mutualistic relations? In making sense of these interspecies interactions, which, despite some costs, are ultimately beneficial to each partner species, zoological approaches operate at the level of populations on an adaptive scale. Anthropologists bring focus on individual actors and their subjective experiences within far more condensed temporospatial ethnographic timescales. This guest editorial brings a multispecies anthropological approach into dialogue with zoological understandings of mutualism. It examines the practical and theoretical potential of mutuality to make sense of relations of domestication. Materialistic profit and market-oriented forms of engagement in the domestic sphere are often detrimental to more-than-human communities. The persistence of different kinds of mutual co-existences, as shown in different forms of care of orphaned animals in Mongolia, Pakistan and Australia, offers an alternative and perhaps more hopeful model of more-than-human engagement in the Anthropocene.  相似文献

Limestone from quarries known to medieval craftsmen and from the monuments they built and embellished, as well as from carvings now in museum collections, has been characterized by neutron activation analysis. Specimens from 38 quarries in the Lutetian and Jurassic limestone formations of France and from sculptures in American and French museums have been tested, and the results have been compiled in a data base to which art historians may refer when attempting to determine provenance for sculptures. Multivariate statistical analysis of concentration data shows stone from a particular quarry in the Paris basin to be compositionally homogeneous and distinguishable from other quarries in the same formation. The same approach to data related to quarries near the Burgundian abbey of Cluny finds general agreement between classifications based on compositional and on petrographic data, but the number of samples available for analysis at the time of writing was insufficient to achieve the finer distinctions reported for the Paris basin.  相似文献
