在茂密纷乱的植被下面.某采砂场的土面被一道黑色的水平带所打断,那是一条窄窄的灰烬层。这个采砂场布满了不规则的台阶和断崖.它的出现打断了摩拉维亚南部葡萄庄园微微起伏的地形。冰川风经由中欧河谷平原携带来细细的沉积物。几千年来形成了数十米厚的地层堆积。这些堆积中埋藏着人类的偶然行为遗留的踪迹:几块燧石、捕获动物的骨骼。或是那来自火塘边的薄薄的灰烬层。它们为人类学家克洛德·列维·斯特劳斯提出的人类区别于世界上其他生物的一种活动——“炊煮”提供了很早的证据.  相似文献

Seasonality determination using stable oxygen isotope (δ18O) analyses in archaeological mollusk shell has been largely limited to aquatic settings where one of the two factors that control shell δ18O – water δ18O (or salinity) and temperature – is assumed to be constant. Open coastal marine environments reflect the former situation, and tropical estuaries constitute the latter. In an effort to expand stable isotope seasonality to an ecological setting where neither variable remains constant, we present a model of annual shell δ18O cycle of aragonite deposition derived from instrumental data on salinity and temperature from San Francisco Bay, California. The predicted range of modeled shell δ18O is consistent with observed δ18O values in prehistoric and modern shells when local conditions are considered. Measurements of δ18O taken at 0 mm and 2 mm from the terminal growth margin were made on 36 archaeological specimens of Macoma nasuta from a late Holocene hunter-gatherer site CA-ALA-17, and season of collection was inferred using the shell δ18O model. We conclude that shellfish exploitation occurred through the year with the exception of fall, which may indicate scheduling conflicts with acorn harvesting or other seasonally abundant resources elsewhere. The model supports the feasibility of stable isotope seasonality studies in temperate estuaries, provided that instrumental records are available to quantify the relevant water conditions at appropriate spatial and temporal scales.  相似文献

In this paper we provide a critical evaluation of the campaign for bilingual road traffic signs in late 1960s and 1970s Wales, examining how Cymdeithas yr Iaith Gymraeg (the Welsh Language Society) came to see English language road signs as mundane, ubiquitous and oppressive symbols of anglicisation and of British/English government authority in Wales. We suggest a rethinking of Michael Billig's concept of ‘banal nationalism’, arguing that while English language road signs may appear as banal symbols and technologies of government authority and control, their banality is only ever experienced from particular perspectives by partial constituencies. For Welsh language campaigners, English language road signs were experienced and criticised as eruptive and disruptive symbols of oppression, rule and colonisation, and in the paper we trace the genesis of the bilingual road signs campaign, British government reactions to proposals for bilingual signs, and the shift in policy which followed the very public support of hundreds of respectable Welsh professionals for the campaign from December 1970. We conclude the paper by examining the work of the Welsh Office's Committee of Inquiry into Bilingual Traffic Signs (the Bowen Committee), and the subsequent disagreements between language campaigners, government scientists and politicians on the issue of language order. Throughout the paper we suggest that it was the ubiquity, functionality and materiality of road signs which made this one of the most effective campaigns carried out by the Welsh Language Society.  相似文献

Islam came to China via the Silk Road, the great trading route beginning in the ancient Chinese capital of Xian. Islam flourished during the brutal but religiously tolerant Mongol Yuan dynasty. Harsh repressive measures were employed against the rebellious Muslims of the Qing dynasty. Islam has survived the tumultuous 20th century and has experienced a revival in the new millennium. Following a brief historical overview, including some of China's relevant history of insurrection, rebellion and reforms, the nature of the Muslim community in China, along with pressing contemporary issues, will be outlined and discussed.  相似文献

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.  相似文献

Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation has in examining the elemental composition of lithic raw materials. Two pXRF instruments, Delta and Omega models both manufactured by Olympus Innov-X Systems, were utilized to obtain the trace element signatures of five fine-grained volcanic sources and four obsidian sources in the Great Basin. We compared the two portable instruments to a wavelength-dispersive instrument extensively calibrated with geologic standards and to a commercial benchtop energy-dispersive system. Our results suggest that the relationships between the data produced by these different instruments are complex, and as we look to the future of pXRF use in archaeological analysis we argue that that the same strict protocols applied in laboratory-based XRF analyses, involving instrument calibration, evaluation of inter-instrument performance, and comparison to accepted geologic standards, need to be applied in pXRF analysis.  相似文献
