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

In this paper the excise tax policy of U.S. state governments is analyzed with special attention to how this policy is influenced by the level of excise taxation in neighboring states, "border-tax effects," and the relative size of the market located across state boundaries. Using a panel data set, state policies towards the taxation of cigarettes, all alcoholic beverages, beer, distilled liquor, motor fuel, and insurance are investigated within the context of a vote-maximizing model of collective decision making. The role of the industry in that state whose goods and services are singled out for special taxation is also examined.  相似文献

For all the recent attention to the problems of child abuse and neglect, this specific policy area has rarely been examined as belonging to the more general area of social service policy. This article begins to remedy this omission. First, the article examines child abuse policy in terms of the conflicts of value faced in the formation of social service policy. Next, the relationship between child abuse and other recent social service issues responding to familial violence or childhood dependency is discussed. Here the article shows that governmental response to child abuse has been used to encourage governmental interest in adoption reform, sexual exploitation of children, domestic violence, and day care.  相似文献

Research around the world has been nearly unanimous about the positive impacts of Indigenous‐led health organizations on Indigenous peoples' qualitative experiences in health care, in the face of often negative experiences in non‐Indigenous‐led health care settings. Urban environments, including health care environments, are areas of increasing attention with regard to Indigenous peoples' health in Canada. In this study, which took place in the northern city of Prince George, British Columbia, 65 Indigenous community members and health services workers participated in interviews and focus groups, describing their experiences with urban Indigenous‐led health organizations—defined in this study as non‐governmental organizations that prioritize the values and practices of local Indigenous communities. Employing perspectives on place and relationships drawn from Indigenous critical theory and Indigenous community resurgence to analyze the findings of this qualitative study leads to a focus on how relationships impact and can even constitute places, enabling new understandings of the roles of Indigenous‐led health organizations in urban Indigenous community resurgence.  相似文献

Many translations of ?āntideva's Bodhicaryāvatāra, a Sanskrit Mahāyāna Buddhist text of seventh/eighth‐century India, have been published since 1892. ?āntideva's Bodhicaryāvatāra is one of the few Indian Mahāyāna Buddhist texts available in Sanskrit and it was influential in Tibetan Buddhist schools. This article explores how translation of the Bodhicaryāvatāra is no longer the preserve of scholars but has moved to being carried out by Buddhist practitioners influenced by Tibetan schools of Buddhism. It shows how translators’ motives for translating the text have reflected changing attitudes to Buddhism and its texts. ?āntideva's Bodhicaryāvatāra has been translated as a source of information, a literary work, an inspirational work and, with the rise of Western interest in Tibetan Buddhism in the late twentieth century, as a vehicle for the transmission of Buddhist teachings. Nevertheless, further scholarly investigation of the Sanskrit text of the Bodhicaryāvatāra remains to be done.  相似文献
