We review the existing data sets for the production and consumption of copper-base objects at Indus sites, outline a working typology for metal objects, and provide new data from on-going analytical work on the copper assemblage from Harappa. The role of metals in the economic and social networks of the Indus tradition is examined in terms of patterns of use and technological style. We note that Indus metalsmiths apparently relied more on procurement of metal ingots or scrap than on primary ingot production through smelting, which would have affected other aspects of Indus metallurgy. Object production did not involve elaborate forms, but may have involved complex alloying. Finally, we conclude that there is no evidence for elite control of metal production, and that access to metals was relatively widespread.  相似文献

ABSTRACT Aviation noise is a harmful pollutant, which has yet to be studied in the environmental justice literature. This paper uses Tobit and logit multivariate regression analyses to analyze noise pollution exposure from a major commercial‐service airport. It addresses the issue of whether people moved to the aviation noise‐impacted areas or the noise encroached on the people, and controls for economic and political costs as well as the possibility of racial and ethnic prejudice. The results indicate that ethnicity is the primary cause of the disproportionate burden of aviation noise pollution borne by Hispanics in the area analyzed.  相似文献

According to economic theory, regional migration is a primary mechanism through which regional wage convergence is predicted to occur. However, this does not necessarily imply that regional migration has an equalizing effect on regional inequality. Despite considerable literatures on regional migration and regional wage inequality, little attention has focused on the relationship between the two. This paper investigates one of the primary mechanisms through which migration affects individual region's wage distributions. It adopts a semiparametric procedure to examine how the regional wage distributions in Great Britain have changed as a result of migration using British Household Panel Survey data for 1991–2007.  相似文献

Vertebrate remains from two stratified sites, the Quebrada Jaguay site (QJ-280) and the Ring Site, reveal details about economic strategies practiced between 13,145 and 7500 cal yr BP on the southern coast of Perú. The near absence of terrestrial resources, a broad continuity in economic activities focused on marine resources, and flexibility within the overall strategy, are among the most interesting aspects of these data. Although they reflect economic and social decisions driven, in part, by fluctuations in environmental conditions, they demonstrate that people were sophisticated strategists actively responding to dynamic environmental conditions.  相似文献

Analyses of fluted point technology and Paleoindian technological risk have contributed to our understanding of human adaptation across North America in the late Pleistocene and early Holocene. However, poor chronological control has dissuaded similar studies of fluted points found in Alaska and northern Yukon and our understanding of their adaptive role in early arctic adaptations remains unclear. Two new archeological sites have provided reliable radiocarbon data and for the first time, a comprehensive analysis of northern fluted points is possible. Here, technological and morphological analyses of northern fluted points are presented, including variables statistically evaluated and compared to a collection of fluted Folsom artifacts serving as a reference. Variation in tool shape was measured using geometric morphometrics, and a new approach to landmark placement designed to characterize basal morphology and allow the analysis to include tool fragments is presented. Results confirm that northern fluted points represent a cohesive technological strategy and are used to formulate hypotheses suggesting its service as a risk-management system promoting ease-of-replacement-after-failure to offset transport costs and reduce risk during long-distance travel.  相似文献
