This study characterizes the degree of calcination of lime in lime plaster samples from Teotihuacan, the capital of a regional state in prehispanic Central Mexico. Lime plaster production consists of multiple steps, from the firing of raw materials to the mixing of lime and aggregate and the final application. While previous studies have focused on the compositional variability, specifically the recipe of lime plasters and mortars, the characterization of lime itself has not been sufficiently addressed. In this study, cathodoluminescence analysis coupled with petrographic and image analyses were employed to examine the degree of calcination of lime. The results of cathodoluminescence petrography were further examined through stable carbon isotope and 14C measurements. It appeared that the results of cathodoluminescence analysis are consistent with those of other analytical methods and that there are diachronic changes in the degree of calcination of lime among lime plaster samples. This implies changes in the organization of lime production, specifically the consistency in the control of firing temperature.  相似文献

In this paper, I focus on Minnesota's unsuccessful attempt to site a hazardous waste stabilization and containment facility, but argue that this should not be seen as another siting failure due to irrational and self-interested citizens who subverted a well-conceived and essential disposal facility, Through a detailed comparison of citizen and elite claims about the facility, I show that many of the sources of disagreement between citizens and siting officials involve value trade-offs rather than technical issues, and contend that state officials' views on these matters should not take precedence. Through "partisan probing," citizens actually contribute to effective policymaking rather than detract from it.  相似文献

Abstract

Folklore research in the United States typically is completed either through academic departments or in organisations designed to create public presentations of traditional expressive culture. These two approaches are termed ‘academic folklore’ and ‘public folklore’. The intellectual history of both approaches has recently been critiqued. One result of this deconstruction is an ambivalence over the historical legacy of key concepts in the study of folklore. Assessing elements of the critical study of folklore’s history – in both academe and the public sector – suggests opportunities for reconstituting the study of traditional culture to establish a more socially responsive approach that is relevant to ways that heritage professionals assess folklore as intangible culture heritage.  相似文献

This paper argues that there were a number of writers in Australia from the late 1880s to the early 1930s who developed what is best described as an economic critique of the workings of democracy. The three writers considered by this paper, Bruce Smith, Edward Shann and W.K. Hancock, all developed critiques of Australian democracy along similar lines. The central feature of their argument was that Australian majoritarian democracy was making poor policy decisions because it attempted to override the laws of economics in the name of the popular will and ethics. They seemed to have believed that this problem would only be resolved once Australia possessed a mature and economically literate population.  相似文献

Excavations at Cladh Hallan, a Bronze Age-Iron Age settlement on South Uist in the Outer Hebrides off the west coast of Scotland, revealed the skeletons of two adults, a sub-adult and a child buried beneath the foundations of three roundhouses. Osteological and isotopic evidence has shown that the male adult skeleton is a composite made up of parts of at least three different individuals. To test the hypothesis that the female skeleton was also a composite we examined ancient DNA from four of its components: the skull, mandible, right humerus and right femur. Seven polymerase chain reactions (PCRs) were attempted, these covering positions 15,996–16,420, 16–132 and 232–368 of the mitochondrial DNA hypervariable I and II regions. Three PCRs were successful for each sample and a total of 55 sequences were obtained from the cloned products. After exclusion of possible contaminating sequences, the remaining 34 were compared. It was concluded that the mandible, humerus and femur come from different individuals. Insufficient data were obtained to draw conclusions regarding the origin of the skull. The presence of two composite skeletons at Cladh Hallan indicates that the merging of identities may have been a deliberate act, perhaps designed to amalgamate different ancestries into a single lineage.  相似文献
