A series of crania from the site of Huamelulpan, Oaxaca, Mexico (400 BC to AD 800), were examined. Four showed notable cultural modifications. One exhibited a healed trephination, while the other three were perforated through the frontal. The cultural context and significance of these modifications is discussed, especially in relationship to the site of Monte Albán, where trephination was more common than anywhere else in Mesoamerica. The post-mortem cranial perforations appear to be connected with the practice of ancestor veneration. © 1997 John Wiley & Sons, Ltd. 相似文献

社会进化的考古学证据
社会文化进化的研究始于19世纪中叶。这些研究难免立足于世界各地有限的民族志轶闻。早期进化论者(如摩尔根、斯宾塞和泰勒)提出过诸如“蒙昧”、“野蛮”和“文明”等术语。 相似文献

Due to the construction of a new North-South subway in Cologne, Roman time harbour sediments were exposed and were sampled
for luminescence dating. A very good independent age control was given by the precise knowledge of the chronology of Roman
activity and by radiocarbon ages of charcoal samples. Hence, different methodological approaches within luminescence dating
were applied for Holocene heterogeneously bleached fluvial samples and were compared to the known ages. For one sample, optically
stimulated luminescence (OSL) dating was applied to coarse-grained quartz using a single aliquot regenerative-dose (SAR) protocol.
After De-measurements, different statistical approaches were tested (i.e. arithmetic mean, median, minimum age model, finite mixture
model, leading edge method and the Fuchs and Lang approach). It is demonstrated that the Fuchs and Lang approach along with
the leading edge method yielded the best matching OSL ages with respect to the known ages. 相似文献

Since the late 17th century, two physical concepts of space exist. Isaac Newton's theory of an immovable ‘absolute space’ made it possible to explain motion and force by the quality of material elements. Less influential was Gottfried Wilhelm Leibniz's concept of space as an ‘order of coexistence’, which focuses, contrary to Newton, on the relationship between material bodies. The author argues that both concepts not only concern physical notions, but also include general models to explain cause, effect and relation. In an analogy to Newton's ‘absolute space’, theories of natural law employ the state of nature to explain society according to the anthropological quality of human beings. Leibniz's concept, in contrast, is used to elaborate theories of complex dynamic interactions and relationships. This essay attempts to illustrate the application of Leibniz's concept with examples of 18th century natural history, demography, economic theory and Charles Bonnet's natural law. 相似文献

There has been an intense scholarly debate about what caused the unprecedented Islamist mass demonstrations in Indonesia in late 2016. Some scholars have argued that increasing intolerance and conservatism among the Muslim population are responsible, while others have disputed such notions, claiming that there is no evidence of widespread support for an Islamist agenda. In this article, we analyse a unique set of polling data to show that a) conservative attitudes among Indonesian Muslims were declining rather than increasing prior to the mobilisation, but that b) around a quarter of Indonesian Muslims do support an Islamist socio-political agenda. Importantly, we demonstrate that this core constituency of conservative Muslims has grown more educated, more affluent and better connected in the last decade or so, increasing its organisational capacity. We argue that this capacity was mobilised at a time when conservative Muslims felt excluded from the current polity, following the end of a decade of accommodation. 相似文献

Discussions on the politics of Chinese engagement with African development have been marked by increasing concern over Chinese use of aid in exchange for preferential energy deals. Normative liberal discourse criticizes the Chinese for disbursing ‘rogue aid’ and undermining good governance in the African continent. These criticisms not only ignore the longer‐term motivations and modalities of Chinese aid and the historical diversity of Chinese relations with Africa, but also uncritically assume ‘Western’ aid to be morally ‘superior’ and ‘more effective’ in terms of development outcomes. This paper consists of three parts. First, it will discuss the debates surrounding Chinese engagement in Africa, especially around aid and development issues. Second, the paper maps the historical development of China–Africa engagement and investigates the impacts of the changing modalities of Chinese aid with reference to case studies of two countries: Angola and Ghana. It then offers a comparative analysis of the similarities and differences between these two cases. The principal argument is that Chinese and Western donors employ different ideologies and practices of governance to conceal their own interests and political discourses in the African continent. 相似文献

Despite the importance of the Clovis–Folsom transition for understanding the history of western North America, its spatiotemporal dynamics remains unclear. Here we report a three-part study in which we investigated the transition using radiocarbon dates from Clovis and Folsom sites. In the first part of the study, we used dates from Folsom site-phases to determine when and where Folsom originated. In the second part of the study, we employed Clovis and Folsom dates in analyses designed to determine whether Folsom spread via demic diffusion or cultural diffusion. In the third part of the study we investigated the velocity of the Clovis–Folsom transition. The analyses suggest that Folsom first appeared around 12,800 calBP in the northern High Plains and spread north and south from there. They also suggest that the spread of Folsom was, at least in part, the result of population expansion. In addition, the analyses indicate that the spread of Folsom was relatively fast for a prehistoric diffusion but well below the maximum velocity that has been estimated for such events. These findings, in turn, have implications for the hypotheses that have been put forward to explain the Clovis–Folsom transition. They refute the idea that the Clovis–Folsom transition resulted from an extraterrestrial impact over northern North America at 12,900 ± 100 calBP but are consistent with the alternative proposal that the transition was a response to climate-driven environmental change. 相似文献
