The lead isotope compositions of many different samples from lead ingots of Roman age from two relicts (from Cabrera, and from Saintes‐Maries‐de‐la‐Mer) of the Western Mediterranean have been measured. Other lead isotope analyses of ores, metals or lead ingots from mines of Sierra Morena and from Cartagena and Sardinia have been accomplished. All the lead isotope measurements have been performed at the Joint Research Centre of the European Union, Ispra (Va), Italy. The samples have been prepared in a class 100 clean room, using only ultrapure reagents and FEP materials. In view of the archaeological arguments, it was possible to believe that the Roman lead ingots of the Saintes‐Maries‐de‐la‐Mer 1 wreck came from Spanish lodes, as well as those of the Cabrera 5 wreck. In fact, while the comparison between the first group of ingots (Cabrera 5) and the lead from Sierra Morena is consistent, the correspondence between the second group of ingots (Saintes‐Maries‐de‐la‐Mer 1) and the Cevennes ores (southern France) gives rise to several problems concerning the archaeological and physical origins. These problems are discussed. 相似文献

China’s economic reforms have exacerbated the problems of over‐grazing and desertification in the country’s pastoral areas. In order to deal with rangeland degradation, the Chinese government has resorted to nationalization, or semi‐privatization. Since the implementation of rangeland policy has proved very difficult, however, experiments with alternative rangeland tenure systems merit our attention. In Ningxia, in northwest China, local attempts have been undertaken to establish communal range management systems with the village as the basic unit of use and control. Some of these management regimes are under severe stress, due to large‐scale digging for medicinal herbs in the grasslands. This digging has resulted in serious conflicts between Han and Hui Muslim Chinese, during which several farmers have been killed. It is against this backdrop that this article explores the institutional dynamics of range management in two different villages. 相似文献

解放太原战役期间战争双方均需在当地动用大量民力、物资,民众动员起着至关重要的作用。中国共产党与阎锡山集团往复争斗近十五年,彼此已相当熟悉,二者的动员模式、技术极其相似,但实践效果却判若两途。通过比较双方在政治宣传、民众保障、组织发动、思想教育等方面的动员活动,可见中国共产党的民众动员更贴合人们的需求,能够获得民众的自觉支持;反观阎锡山方面却是官民区隔、上下离心,浩大的动员声势常流于表面。二者迥异的组织能力和政党文化影响了实际动员效果。太原战役期间双方在动员中呈现的差异不啻是当时国共之别的重要缩影,也折射出左右两党最终胜败的内在原因。 相似文献

This paper describes wheel-made wares of the Late Bronze Age found in the Iberian Peninsula, including Mycenaean imports, and considers their origins and possible meaning for the introduction of the technology of wheel-turning. Such an innovation is documented in metal vessels and in jewellery of 'Villena-Estremoz' before the phase of Phoenician colonization in the eighth century BC. 相似文献

Southeastern Central Europe is quite rich in finds of progressive Neandertals from Middle Paleolithic contexts and early modern humans associated with evolved Upper Paleolithic (Aurignacian and Pavlovian). There are no human fossils that can be related to the transitional Middle-Upper Paleolithic units (the Bohunician and the Szeletian); thus, from anthropology we know only that the transitional period began with Neandertals and ended with modern humans. The archaeological record is more complex. The Jankovichian industries of Hungary differ from the mostly non-Levallois Middle Paleolithic of Central Europe in the presence of some Levallois; they seem to be technologically related to the Levallois-Leptolithic Bohunician industries of Moravia, dated to 43,000–38,000 B.P., which are the first transitional Upper Paleolithic unit. The appearance of the Szeletian before 42,000 B.P. in Hungary and at about 39,000 in Moravia represents a technological variation of the transition, although retaining marked local Middle Paleolithic elements. The date of the appearance of the typical Aurignacian, the first culture clearly related to modern humans, is unclear, but it certainly developed after 36,000 B.P. and has several dates between 35,000 and 30,000 B.P. 相似文献
