We report the results of LA-ICP-MS analysis of 402 quartzite samples representing 48 collection loci in the Upper Gunnison Basin (UGB), Colorado and determine the extent to which the sources can be geochemically discriminated from one another using this non-destructive technique. The ability to differentiate among the sources would open the door to provenance studies of the quartzite chipped-stone tools and debitage that constitute 95% or more of most of the 3000-plus prehistoric site assemblages documented in the UGB. Our samples represent prehistorically quarried and non-quarried quartzite sources, including outcrop (primary) and gravel (secondary) deposits. The results reveal spatial and chronological trends in quartzite elemental composition that can be exploited for provenance determinations of quartzite artifacts from UGB sites, albeit using an assemblage-based sourcing strategy that differs from the familiar approach of “matching” obsidian artifacts to their statistically likeliest geological source. We offer a preliminary version of a sourcing protocol for UGB quartzite. 相似文献

The author examines the role played by the economic geography of the former Soviet Union in the evolution of labor relations in Russian industry, using the iron and steel industry as a case study. More specifically, three regional factors are analyzed as they affect enterprise economic strategies, organization, and management-labor relations: (1) the inherited industrial structure; (2) the degree of product specialization at the regional level; and (3) the level and sophistication of regional political and labor structures combined with the presence (or lack of same) of a “regional agenda.” These factors are examined within the context of a model predicting several possible variants of post-communist labor relations at the enterprise level. 36 references. 相似文献

Hermann Oppenheim was influential in many areas of neurology, but his ideas about music are relatively unknown. In 1888, he published a paper that outlined how the assessment of music skills in patients with aphasia could lead to a better understanding of aphasia and language. Oppenheim conducted the first comprehensive music assessment as part of a neurologic examination and presented the first case series of music in aphasia. His paper was widely cited and had significant influence over the next 30 years. Although largely unrecognized as such, Oppenheim was an important historical figure in the study of music and neurology. 相似文献

In this paper we use a small number of in-depth interviews with parents with primary school children to examine social mixing and friendship practices in two super-diverse North London boroughs. In these complex geographical contexts, characterized by gentrification processes and old and new migrations, we suggest that primary schools are convergent places where adults and children from different backgrounds are likely to meet and interact, and the paper explores the extent to which adults and children, thrown together in and through these sites, negotiate relationships with those who are differently socially and culturally situated to themselves. Informed by the interview narratives, the paper highlights the importance of focusing on the micro, quotidian ways in which differences in social and/or ethnic background shape those relationships and it explores some instances of the ways in which those differences are routinely encountered, managed and/or avoided. In this way the paper contributes theoretical and empirical nuance to current concerns around difference and diversity and the interactions of complex urban populations by ‘adding’ social class to everyday multiculture perspectives and everyday multiculture perspectives to urban middle class debates. 相似文献

This paper focuses on the process of negotiating standards of reliable performance in the introduction of a new technology as a way to explain the eventual success of one device over its competitors. Using the introduction of the antilock braking system as a case study, the author examines three systems, produced by Dunlop, Kelsey‐Hayes, and Bendix, which failed to achieve success on the market and contrasts them with the work of engineers at Robert Bosch, GmbH, whose ABS became the dominant antilock technology by the 1980s. An important aspect of the social construction of technology, the problem of reliability is one only addressed through a network of social and technical factors. 相似文献
