Micromorphological analysis of sediments from the Middle Stone Age site of Sibudu Cave, KwaZulu-Natal, South Africa, provides
a high-resolution sequence and evidence of site formation processes of predominantly anthropogenic deposits. This methodology
allows for a detailed interpretation of individual anthropogenic activities, including the construction of hearths and bedding
and the maintenance of occupational surfaces through the sweep out of hearths and the repeated burning of bedding. This analysis
also provides a context for evaluating other studies at the site relating to magnetic susceptibility, paleobotany, paleozoology,
anthracology, and studies of ochre. 相似文献

Research on past human diets in the southern Lake Titicaca Basin has directed us to investigate the carbon and nitrogen stable isotopes of an important dietary element, fish. By completing a range of analyses on modern and archaeological fish remains, we contribute to two related issues regarding the application of stable isotope analysis of archaeological fish remains and in turn their place within human diet. The first issue is the potential carbon and nitrogen isotope values of prehistoric fish (and how these would impact human dietary isotopic data), and the second is the observed changes in the fish isotopes through time. Out of this work we provide quantitative isotope relationships between fish tissues with and without lipid extraction, and a qualitative analysis of the isotopic relationships between fish tissues, allowing archaeologists to understand these relationships and how these values can be applied in future research. We test a mathematical lipid normalization equation to examine whether future researchers will need to perform lipid extraction procedures for Lake Titicaca fish. We also analyze a number of aquatic plants to better understand the range of isotopic signatures of the Lake Titicaca ecosystem. We use these data to better understand prehistoric human diet and the role that fish may have played in the past as well as potential changes in local lake ecology through time. 相似文献

Abstract: This article takes issue with a mode of argumentation advanced by a number of left-leaning, radical scholars, including those associated with China's New Left, about the causes of the Tibetan unrest in China in spring 2008. According to this stance, the Tibetan protests were the result of external manipulation by neoconservative, reactionary forces, ranging from the CIA to the Dalai Lama. The unstated premise of this response is that taking a critical stance against western imperialism and neoliberal globalization necessitates a defense of China's policies in Tibet. Such arguments take the form of unfavorable comparisons between Tibetans and Palestinians especially because the former are often romanticized, suggestions that Tibetans are unfortunate ideological victims of US-funded propaganda, and claims that they should be grateful for Chinese state-funded development. This response renders Tibetans incapable of being authentic political subjects. A radical stance on Western imperialism and capitalism should reject such reductionism. 相似文献

We conducted experiments to compare the micromorphological signatures of modern burnt sedge and grass bedding to laminated layers of carbonized material and phytoliths in Middle Stone Age deposits at the shelter, Sibudu. The experiments were designed to clarify the formation processes associated with the laminated layers and to investigate whether these previously identified layers of bedding were deliberately burned or not. The results indicate that the laminated layers were most likely produced by human activity related to the construction, maintenance and burning of bedding. Furthermore, our experiments demonstrate that large volumes of vegetal material could have produced the relatively thin, archaeological deposits of burnt bedding. 相似文献

In the spring of 2006, Tibetans in China set fire to more than a million dollars worth of otter, leopard and tiger pelts. The numerous bonfires were a response to the 14th Dalai Lama's statement, made at the Kalachakra Initiation Ceremony in India, that Tibetans should cease wearing such pelts. The Chinese state interpreted this as an act of loyalty to the Dalai Lama and this evidence of multiple overlapping sovereignties as a threat to its exclusive territorial sovereignty. An effort to clarify this space invited a sovereign invocation of the exception, as salaried employees were forced to wear endangered animal pelts, violating Chinese national law. A conjunctural analysis of the Dalai Lama's speech and the subsequent burnings demonstrates that contrary to prevailing narratives, transnational environmental advocacy played a key role. The conjuncture in which these events took place was shaped by multiple competing entanglements of Chinese, Indian, and Tibetan sovereignties with nature protection and transnational activism. Two distinct assemblages, shaped by power relations and the politics of sovereignty, formed around protecting the tiger across the Himalayas, with dramatically different effects. The case shows that far from post-sovereign environmental governance, nature and sovereignty remain inextricably entangled, and illustrates how multiple modes to construct and defend state sovereignty come into conflict with each other. 相似文献

Sourcing ceramics with portable XRF spectrometers? A comparison with INAA using Mimbres pottery from the American Southwest 总被引:1,自引:0,他引:1

Seventy-five intact Mimbres and Jornada pottery sherds from the American Southwest were analyzed by portable XRF and instrumental neutron activation analysis (INAA). Examination of the data demonstrates that INAA and portable XRF results for elements common to both analyses can be used to construct similar compositional groups. When individual compositional groups are compared to one another, it is apparent that unambiguous separation of compositional groups is challenging by portable XRF given (1) the limited number of key discriminating elements that can be measured relative to INAA, and (2) the relative analytical precision and accuracy of portable XRF for measurements of intact heterogeneous ceramics. We conclude that sourcing intact ceramics by portable XRF is challenging and that bulk analytical measurements, such as INAA, remain a better approach for sourcing archaeological pottery. 相似文献

This article explores the efforts of French Catholic, Protestant, and Jewish women to morally, spiritually, and physically protect immigrant and migrant women and girls in the late nineteenth and early twentieth centuries. Women of faith worried about the dangers posed by the white slave trade, and they feared the loss of spiritual consciousness among women living far from their families and their places of worship. In response to these concerns, they developed numerous faith-based international organizations aimed at protecting vulnerable working-class immigrants. Upper-class women's work in immigrant aid societies allowed them to take on much greater social and religious leadership roles than they had in the past. Likewise, the intricate, international networks that these women developed contributed to the building of international cooperation throughout Europe. 相似文献
