Recently, two problems have been recognized with the United States Southwest archaeomagnetic master curve (Eighmy, 1991; LaBelle & Eighmy, 1997; Sternberg, 1989). One of these problems, the damping problem, is inherent to the moving window method of curve construction proposed by Sternberg (1989). The other is due to the fact that the small number of independently dated virtual geomagnetic pole determinations available for the period between 900–1100 are not representative of secular variation during this period. The analyses presented here confirm the existence of these two problems and suggest that they distort the curve by less than 1·0° and between 1·0° and 2·0° respectively. Based on these findings, a new curve is proposed for the U.S. Southwest.  相似文献

In late nineteenth- and early twentieth-century America, the consumption of American-made goods was seen as an expression of one’s patriotism and loyalty to the nation. According to a number of historical archaeological case studies, racialized groups, such as African Americans and Chinese Americans, used consumption as a way of gaining access to the full benefits of American citizenship typically reserved for individuals deemed “white” by law. The material culture of Mexican immigrants living in early twentieth-century Los Angeles tells a slightly different tale. Despite being ascribed a legal whiteness, archaeological and documentary data suggest that Mexican immigrants expressed ambivalence toward their consumption of American goods and outright rejected the notion that exerting such buying power would lead to a broader acceptance in Anglo American society.  相似文献

This paper presents 19 AMS radiocarbon dates from nine pre-Hispanic Caribbean (Taíno/Lucayan) wooden sculptures in the British Museum collections, provenanced to Jamaica, Hispaniola and the Bahamas. Together with strontium isotope results and wood and resin identifications, these data build a material and chronological context for some of the most recognised examples of Taíno art – from duhos (ceremonial seats) and cemís (free standing depictions of deities, ancestors and spirits) to canopied stands used to hold hallucinogenic drugs during the cohoba ceremony. Each sculpture widens our understanding of Caribbean carving traditions, stylistic variation, chronologies and material resource utilisation. A group of three sculptures recovered from Carpenters Mountains, Jamaica, carved by AD 1300 and brought together as a ceremonial ‘set’, each appear to have had their inlays renewed over a century later, suggesting long-term use. Three key examples of the main Caribbean duho categories (high-back, low-back and extended), provide insights into the diversity of styles present in the region post-AD 1100. The British Museum's corpus enables an exploration of regional styles, and potentially the work of individual artists.  相似文献

Few contemporary issues have received as much sustained attention as the deterioration of the quality of our natural environment and, particularly, the need to manage the trade-off between economic growth and the quality of that environment. This paper discusses research currently under way to develop a land-use planning methodology that will help planners address the trade-offs between environmental quality and economic development. The methodology is used to evaluate the social, economic, and environmental impact of alternative land-use plans. The methodology consists of a regional analysis submodel and a site analysis submodel. The first component is based on an expanded input-output analysis incorporating land use, resource inputs, and waste-emission outputs. The second component is an empirical analysis based on the specific suitability and compatibility of proposed land-use development packages. The land-use planning model developed is applied to a case-study area centered on Charleston, South Carolina.  相似文献

A set of 104 independently dated archaeomagnetic directions was used to extend the U.S. Southwest reference curve back to 375 cal BC and to calculate isolated mean VGPs centered on 960 cal BC and 2390 cal BC. Prior to this study, most U.S. Southwest reference curves extended to only ca. AD 585. This study employed Sternberg’s moving window technique with variably sized windows, rather than fixed windows, to smooth the dataset into a continuous curve. The size of each averaging window was determined by the density of data captured by the window, such that each window had a minimum data density of 5.0 and a minimum window size of 50 years. This approach differs from previous studies in the U.S. Southwest, which have applied a uniformly sized averaging window to a dataset regardless of the temporal distribution of the data.  相似文献

Coarse earthenware production at the Dutch East India Company (VOC) Cape settlement began shortly after the Company established its mercantile entrepôt on the shores of Table Bay in 1652. Made by European Company potters, these vessels reproduced the forms of the homeland in the raw materials of the colony. A history of VOC pottery manufacture and a typological examination of the products illustrates how the global movements of mercantile capitalism combined with the local circumstances of the Cape settlement to create a material form reminiscent of Europe, but purely colonial in the dynamics of its production and use.  相似文献

Abstract: After almost 30 years of Federal retraction from anti‐poverty initiatives, many American cities have been left with the dual burden of intensified poverty and far fewer resources to combat the problem. At the same time, such devolution has afforded cities the authority to forge poverty policy at the local level, such that the familiar neoliberal imperatives of state retraction and the mobilization of territory for capitalist expansion are frequently tempered by more progressive political imperatives at the local scale. What has thus emerged is a deeply ambivalent policy landscape, of which “kinder and gentler” poverty management strategies are a central feature. Using the example of a recent homeless program in San Francisco, “Care Not Cash”, this paper argues that such poverty management strategies, while less punitive than their revanchist predecessors, nonetheless introduce a new set of exclusions to the service delivery system, many of which are obscured by the language of compassion. In order to illustrate those new exclusions, I describe the city's homeless geographies—the public spaces, shelters, service sites, and housing models—that have been produced and reconfigured according to a logic of managing homelessness through the provision of care.  相似文献
