Archaeomagnetic dating of samples from a brick kiln discovered at Dogmersfield Park has been achieved using both field direction and intensity. Detailed rock-magnetic properties and microwave archaeointensities have already been studied and published elsewhere [Ll. Casas, J. Shaw, M. Gich, J.A. Share, High-quality microwave archaeointensity determinations from an early 18th century brick kiln, Geophys. J. Int. 161 (2005) 653–661]. The archaeomagnetic measurements were assigned time-probability distributions by comparing with predictions from a global model at the sampling site, this procedure suppresses errors arising from relocation to a common central reference location. All three probability distributions consistently indicate the same age (∼AD 1700). Once the probability distributions are combined a narrower probability distribution is obtained, stressing the importance of pursuing combined (directional and intensity) archaeomagnetic analyses. The inferred age is also highly consistent with available historical evidence. 相似文献

We present the results of faunal analyses from the recently excavated site of Kuidas Spring in north-western Namibia. The site includes rock shelters, stone circles and stone cairns. Stone circles, which were built during the last 1500 years, are widely distributed over much of Namibia and parts of the Northern Cape Province of South Africa. Current interpretations suggest that after the introduction of livestock 2300 years ago, hunter-gatherers who became herders built stone circle settlements. However, our results based on the faunal remains indicate that Kuidas Spring was exploited as a hunting resource, and whether or not herders with (or without their) livestock occupied or visited the site remains unconfirmed. We also found that gemsbok made use of stone circles at Kuidas Spring when these features were not inhabited and show how such activity might impact the interpretation of archaeological material. 相似文献

A microfluidic device has been developed for the sex identification of ancient DNA samples and works by manipulating liquids within an environment of micrometer dimensions. In this work a range of microfluidic DNA extraction methods were evaluated for their compatibility with ancient DNA samples, and the use of streptavidin-coated super paramagnetic particles to isolate biotin-labeled abasic sites within damaged DNA was shown to be the most reproducible. Polymerase chain reaction-based DNA amplification was possible on the microfluidic device when less than 50 pg of template DNA was added. As a proof-of-principle, powdered bone samples were analysed using the integrated methodology developed. Following conventional capillary gel electrophoresis, two out of the three samples produced positive amplification results and were successfully identified as female. These sex identifications were corroborated by independent Amelogenin, anthropological and Y chromosome analysis. The work reported here is the first step in the development of a complete miniaturized microfluidic system that would enable on-site ancient DNA analysis. 相似文献

This paper compares and contrasts Russian frontier experiences on the northern and southern parts of the European plain during the Romanov era (1613-1917). Both were “open” frontiers, in Turner's sense of a frontier as the “hither edge of free land,” but their environments and the settlement processes which affected them were very different. It is suggested that the character of a frontier society is decisively influenced by the process whereby settlers must adapt to their new environment, the features which attract them to that environment, and the character of the pre-existing inhabitants. The northern frontier formed part of what Meinig has called a “boreal riverine empire” with a harsh environment, to which paradoxically the Russians found it relatively easy to adapt, the great attraction of fur-bearing animals and reasonably benign relations with native peoples. By contrast, the southern frontier was a “frontier of exclusion,” following Lattimore's phrase, with hostile indigenes, a natural environment demanding special methods of adaptation, but with many more attractions than the north. Such contrasts gave rise to considerable differences in the settlement process, in the character of land allocation and in the type of society evolving subsequently, with long-term consequences for emerging human landscapes. 相似文献

Abstract: This paper provides a critical analysis of how and why US‐led drone warfare is conducted in the Federally Administered Tribal Areas (FATA) of Pakistan. First, we provide detailed statistics on the scale and funding of US drone operations, noting a rapid acceleration of its adoption by the military. This is then situated within an overarching narrative of the logic of “targeting”. Second, we study a legal document called the “Frontier Crimes Regulation” of 1901 that defines the relationship of FATA to the rest of Pakistan as an “exceptional” place. In the third section, we argue that the drone is a political actor with a fetishized existence, and this enables it to violate sovereign Pakistani territory. In this sense, the continued violence waged by robots in Pakistan's tribal areas is a result of the deadly interaction between law and technology. The paper concludes by noting the proliferation of drones in everyday life. 相似文献
