Several samples of pyramids from Giza were obtained. The samples were analysed by scanning electron microscopy, electron diffraction by X-rays, powder X-ray diffraction, inductively coupled plasmography, Fourier-transform infrared spectroscopy and other techniques. Some scientists who have recently studied the pyramids have suggested that the pyramids were poured into place, stone by stone. The prevailing theory among Egyptologists is, of course, that the pyramids were built from blocks of natural stone. All of the results obtained during this study directly support the concept that the pyramids are made of limestone and are not cementitious in nature.  相似文献

Lillian Ball's art project WATERWASH creates a new ecological imaginary in the South Bronx. Building on a tradition of ‘maintenance art’, the work exhibits the power of soil, plants and microorganisms to clean water – in effect maintaining urban water. An overarching goal of WATERWASH is to educate local people about the metabolism of urban water, causes of river pollution, and to familiarize them with the capacity of soil and plants to respond to that problem. As part of its creation, the project provided diverse groups of people with opportunities to participate, including a group of Bronx youth who assisted in planting the wetland. Several of these apprentices will be involved in future monitoring of the effectiveness of the wetland in mitigating parking lot runoff. I use Isabelle Stengers' notion of ‘diplomacy’ to interrogate the efforts of the artist in negotiating and creating an occasion in which people with divergent interests can both recognize and maintain the relationships of care that sustain them. In effect, this effort extends the feminist discourse of maintenance work to include that undertaken by the ‘other-than-human’.  相似文献

This article analyses Dabiq magazine to explore the strategic logic of Islamic State (IS) appeals to English-speaking Muslims. It offers the field a conceptual framework through which to analyse IS’s communications strategy and a top-down empirical study of Dabiq’s contents. This paper argues that Dabiq appeals to its audiences by strategically designing in-group identity, Other, solution and crisis constructs which it leverages via value-, crisis- and dichotomy-reinforcing narratives. By fusing identity- and rational-choice appeals, IS provides its audiences with a powerful ‘competitive system of meaning’ that is designed to shape its readership’s perceptions, polarise their support and drive their radicalisation.  相似文献

Seasonal patterns of Native American residence and use of shell mounds of the San Francisco Bay area, California are of great interest. This work investigates seasonal occupation by means of a new method for interpretation of geochemical data from Mytilus trossulus specimens recovered from one of these structures, the Ellis Landing Shell Mound (CA-CCO-295). The approach, which is suitable for relatively small shell fragments from a variety of archaeological contexts, is used to infer the environmental conditions (temperature and salinity of ambient water) at harvest time, compared with average conditions for the period, and thus estimate the season during which the shells were harvested. This information, in turn, is employed to evaluate current models about the growth and construction of prehistoric shell mounds in San Francisco Bay. The method was applied to seven different lenses in the shell mound ranging in age from ∼240 cal yr BP to ∼3510 cal yr BP. We found that, although seasonal occupation varied over time, it generally was confined to summer through late fall, with little indication of winter gathering. Our findings suggest that California shell mounds, such as Ellis Landing, were constructed in a very different manner than some other mounded places used by contemporaneous hunter-gatherers elsewhere in North America.  相似文献

Abstract: Access to treatment for HIV/AIDS became a flashpoint for global justice struggles in the late 1990s. An expanding international response, premised to a significant extent on the idea of HIV/AIDS as an exceptional global problem, has since delivered treatment, care and prevention to growing numbers of people. HIV/AIDS exceptionalism, however, has increasingly been questioned, many aspects of the response have been critiqued and donor funding has started to decline. I argue that, having been framed as an exceptional humanitarian emergency, the question of HIV/AIDS as a global problem is increasingly located within a discourse of scarcity. Tracking the growing entanglement of global HIV/AIDS relief with neoliberal governmentality and the emergence of something I term therapeutic neoliberalism, I argue that the shift from a rationality of salvation to one of administration poses new challenges for global health activism. Questioning the discourse of scarcity remains essential to an alternative global health agenda.  相似文献
