The characterization of a ceremonial bronze axe is described. The axe is assigned to the Santamarian culture of north‐west Argentina, c. 1000–1470 ad, and was selected to increase presently limited knowledge of prehistoric metallurgy in the Andean region of Argentina. The characterization methods used were electron probe microanalysis, gamma radiography, X‐ray diffraction, optical metallography and microhardness testing. The axe was well cast in a bivalve mould, with the only defects in the area of an ancient fracture. The analysis showed that it is made from a tin bronze with a, probably, accidental addition of lead. Arsenic was found as a surface contamination, probably deriving from arsenic in the water of the stream in which the axe was found. The axe shows that Santamarian craftsmen had the skill to decorate the axe in an artistic style with a strong local accent while providing a functional, annealed and cold‐worked cutting edge. 相似文献

‘Black Economic Empowerment’ (BEE) has been a major policy thrust of the democratic governments in South Africa since 1994 in attempting to redress the effects of apartheid. In this article, we explore the historical precedents to BEE in South Africa, review the different steps taken in promoting it, and assess some of its outcomes to date. We argue that BEE can take only limited forms because of the economic policy constraints in which it has been incorporated. Moreover, these forms have an increasingly managerial logic that further restricts what can be achieved. Short of a major shift in conceptions of — and policy for — BEE, meaningful ‘empowerment’ is unlikely to take place. 相似文献

Anthropologists are chronologically only the latest to have adopted justice (and injustice) as an object of (critical) inquiry. Even among anthropologists, however, the radical critical cry that law is the instrument par excellence of control and repression, has today fallen out of fashion. Starting from the Afghan case, in this paper I reflect on law as a potential source of violence and as an anti‐value – in the sense of being in antithesis with accepted social values – in the contemporary global scenario. My focus here is neither on the uses that can be made of law nor on the outcomes of its interpretation and application. Rather, I am interested in what law can generate when it betrays social values and sentiments of justice. 相似文献

Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage. 相似文献

In the literature, the ‘Overview Maps of Imperial Territories’ or Huangyu quanlan tu 皇輿全覽圖, is mostly referred to as ‘the Jesuit atlas of China’. The reason is that this early eighteenth-century atlas of all Qing China’s territories plus Korea and Tibet is assumed to have resulted from European missionaries importing European cartographic practices. In this essay, I argue that this view is outdated and can no longer be sustained. By revisiting the background of the missionaries’ involvement in cartographic exchanges between Asia and Europe, the techniques used for surveying Qing territories and the production of the resulting atlases, I show that the mapping project behind the ‘Overview Maps of Imperial Territories’ is best understood as a creative answer to the unique needs of Qing frontier management and imperial control, made possible by the integration, in mensurational and in representational terms, of European and East Asian cartographic practices. 相似文献
