A new method for determining the maximum firing temperature of ceramics and burnt clay is presented. The technique relies on measuring the magnetic susceptibility on a step-wise re-fired sample. The validity of the method has been tested by determining firing temperatures of two sets of clay samples fired at temperatures ranging from 400 to 1000 °C. Aliquots of the same samples have been studied petrographically by optical microscopy on thin sections and analyzed by powder X-ray diffraction in order to monitor structural and mineralogical changes as a function of temperature. The method is demonstrated on samples from four geographically widely different sites and it is applied to a larger set of ceramics of Late (ca. AD 900–AD 1450) and Inca (ca. AD 1480–AD 1532) periods from the Northwestern Argentine region, dating to a limited period of time prior to the fall of the Inca Empire. The method is shown to be a powerful tool in revealing archaeological information about the change in firing technologies in the pre-Hispanic societies in the Andean area through time. 相似文献

Public authority does not always fall within the exclusive realm of government institutions; in some contexts, institutional competition is intense and a range of ostensibly a‐political situations become actively politicized. Africa has no shortage of institutions which attempt to exercise public authority: not only are multiple layers and branches of government institutions present and active to various degrees, but so‐called traditional institutions bolstered by government recognition also vie for public authority, and new emerging institutions and organizations also enter the field. The practices of these institutions make concepts such as public authority, legitimacy, belonging, citizenship and territory highly relevant. This article proposes an analytical strategy for the understanding of public authority in such contexts. It draws on research from anthropologists, geographers, political scientists and social scientists working on Africa, in an attempt to explore a set of questions related to a variety of political practices and their institutional ramifications. 相似文献

We report on energy-dispersive X-ray fluorescence (EDXRF) sourcing of 807 basalt artifacts and 34 basalt ecofacts recovered from stratified midden at Nu‘alolo Kai, Kaua‘i. These data are compared with EDXRF analyses of 473 alluvial pebbles from Waimea Canyon, 34 adzes from the Kaua‘i Museum, and published geochemical data for Kaua‘i basalts. Formal tools, such as adzes, chisels, and mirrors were predominantly manufactured from sources not available at Nu‘alolo Kai. Most adzes and chisels are consistent with sources available elsewhere on Kaua‘i, but two basalt mirrors are outside the expected geochemical range of Kaua‘i basalts. In contrast, almost all expedient tools were manufactured from basalts available at Nu‘alolo Kai. These findings support the existence of an island-wide distribution system for adze material on Kaua‘i, and challenges extant models of pre-contact Hawaiian economics to consider the mechanisms through which specialized commodities were produced and distributed. 相似文献

The increasing international mobility of labor and the inability of the state to control immigration flows completely have forced labor union leaders to reconsider their attitudes toward immigration from a more global perspective. The result is a tacit alliance between labor leaders and employers in favor of moderately open immigration policies. In Spain, this unusual alliance manifested itself in the 1996 Spanish immigration reform. 相似文献

The aim of this study is to find out whether bromide was able to cause conversion of epilepsy to psychosis i.e., so-called paradoxical normalization such as has been seen in treatment with modern antiepileptic drugs. Spontaneous conversion has been known for three hundred years. Locock introduced bromide in the treatment of epilepsy in 1857. Belgrave wrote in 1868 on its effect on epileptic attacks and concommitant insanity. In 1868 Holm observed reduction of the frequency of seizures at the same time as psychotic symptoms or just dysphoria. In 1875 Voisin described a dose-dependent intoxication with psychosis and/or neurological signs. Stark in 1875 and Bannister in 1881 were the first to clearly describe the antagonism between epileptic seizures and psychotic symptoms, an antagonism or conversion described by many authors, both in cases with high and low dosage, and with and without intoxication. Thus, the title of this paper should be answered in the affirmative. Bromide has been used as a sedative and has rarely caused intoxication. Thus the presence of epilepsy is not a condition for the development of bromide intoxication. A case with epilepsy and fatal massive bromide intoxication is reported. It is discussed whether the pathological findings give support to Wolf's hypothesis of latent epileptic activity in subcortical pathways during "normalization". 相似文献

We examine evidence for prehistoric diet in the Fiji Islands through the analysis of stable isotope ratios (δ13C and δ15N) for 26 samples of human and animal bones from various archaeological sites, time periods, and local environments. The oldest individuals in this study, dating to about 2700 BP and living on the small island of Waya, consumed a predominantly marine-based diet. Subsequent populations on this island showed reduced consumption of marine resources, with greater reliance on terrestrial ones, throughout the cultural sequence. In contrast, populations of humans and pigs living inland on Viti Levu, the largest island, relied on terrestrial resources since at least 1500 BP. Thus, our results suggest that human and pig diets throughout Fijian prehistory relied variably on marine or terrestrial resources, and this distinction is largely a product of geography. This finding and our analyses provide a model for understanding ancient diets in Remote Oceania. 相似文献
