水资源短缺一直制约着京津唐地区经济和社会的发展。20世纪70年代,因缺水引发的经济、社会问题逐渐凸显,促使中央和地方政府开始考虑实施跨流域调水工程。引滦工程作为北方最大的跨流域调水工程,其决策经历了曲折的过程。1958年,北京和唐山曾分别提出引滦河水的设想,唐山还实施了引滦入还和引还入陡工程。1972年,海河流域大旱促使中央做出加快实施引滦工程的决定,但由于地质情况复杂等原因,引滦工程设计方案被反复修改。1981年,天津提出了单独引滦济津路线并得到了中央的支持。引滦工程对缓解京津唐用水紧张发挥了重要作用,天津是引滦工程受益最大的地区。  相似文献

James Hamilton, duke of Hamilton and the Scots jacobites are generally linked in analyses of the final years of the Scots polity. Indeed, Hamilton is often presented as the leader of the jacobite party in the Scottish parliament. Yet both contemporaries and historians have been unsure what to make of his on-again, off-again, conduct with respect to the exiled Stuarts and France. This has fuelled an ongoing debate about Hamilton's erratic and highly enigmatic behaviour during the winter of 1706–7, when the Union was passing the Scottish parliament. Was he genuinely opposing the Union? Was he duped by the court? Or was he, ‘bought and sold for English gold ’? This essay takes a fresh look at the duke and his part in the Union crisis in the light of new and previously underused jacobite sources with a view to better understanding Hamilton's aims, objectives, and influence with this crucial group. Only the jacobites and the Cameronians were potentially willing to take their opposition to the Union to God's Acre. But neither party immediately flew to arms in response to passage of a union they both believed was a betrayal of everything they held dear, and Hamilton was a major factor in their failure to do so. This essay thus takes a close look at the duke's part in preventing a major national uprising against the Union in the winter of 1706–7 and advances a new interpretation of his conduct and significance throughout the Union crisis.  相似文献

This article examines relations in thirteenth-century Tuscany between the minor rural aristocracy and great rural lords, that is, those based outside cities. The subject is approached through a study based on three families, with special emphasis on the way they were bound to the extended family of the Guidi counts, who were prominent at the highest level in the thirteenth-century kingdom of Italy. In the thirteenth century, attendance on the counts was not attractive to families of the minor aristocracy: it was universally acknowledged that the great rural lords of Tuscany had little to offer their adherents in terms of wealth, power and prestige, incentives which could be obtained from the cities of the region. Minor aristocrats who chose to live as professional soldiers were particularly attracted to the cities, which were always in need of soldiers for their armies.  相似文献

Eastern North America in late Pleistocene times was characterized by two major environmental regions: a periglacial tundra or open spruce parkland and an extensive complex boreal/deciduous forest in the unglaciated, lower latitudes. These environments selected for different adaptive strategies on the part of human foraging groups—known archaeologically as Paleoindians. Those in the tundra and tundra-forest region were highly mobile, possibly specialized hunters, exploiting caribou; those in the forest were generalists, exploiting a variety of subsistence resources with a less mobile settlement system. There is little evidence in either area for hunting of Pleistocene megafauna. These differences in adaptive strategies are reflected in the record of sites and isolated fluted points scattered throughout the region, as well as aspects of tool technology, function, and patterns of stone use.  相似文献

This article introduces our themed section on The Left(s) and Nationalism(s), which provides a comparative analysis of the relationship between nationalism and different left-wing parties in Western Europe. It highlights the innovative comparative perspectives offered by this themed section, which not only concerns a series of different geographical cases studies but also involves the ideological plurality of the Left. The larger research question that our contributors address is how different left-wing parties have dealt with the inherent ideological tension between the universality claimed by the Left and the particularism inherent in nationalism, as a doctrine and a principle of political legitimacy. The article stresses three main contributions of our themed section: (1) Western European left-wing parties do engage with the themes of nationalism and nationhood, but they often rely on convenient silence to solve some of the contradictions with their progressive ideology. (2) None of these parties have formulated thick versions of the respective national identities. (3) State-wide left-wing parties have used instrumental conceptions of nationhood to address the challenge of separatist parties, but only with mixed results.  相似文献

This paper is based on the 2018 Neil Smith Lecture presented at the University of St Andrews. It considers the plantation past/futures of Sapelo Island, Georgia, one of the Sea Islands forming an archipelago along the US Southeastern coast. I work through the abolitionist efforts of the Saltwater Geechee’s who have resided there since at least 1803 to better understand how we can mobilise an emancipatory politics of land and property and to produce commons that work to repair and heal the violence done through enslavement and ongoing displacement. I weave together a series of historical threads to better situate linked ideas of abolition democracy and abolition geography, and to extend the notion of abolition ecology as a strategic notion to connect Eurocentric based political ecologies with the emancipatory tradition of Black geographies.  相似文献

古人发型是文化界长期关注的一个重要现象。发型不仅是时代的特征与时尚的符号,也是各个族群的辨识标志。从北朝到隋唐的中古社会,"剪头胡雏"的文物图像屡屡出现,一般来说,此类胡人形象是剪发而不是束发,在当时以"高髻为尚"的社会习俗中,"剪头胡雏"发型是有着"阶级感"的存在,是有关底层胡人的直观艺术产物。也说明当时入华胡人还没有彻底"汉化",仍然保留着本族群的发型特征。该发式是胡人与汉人的区别,也是其身份归属的象征。  相似文献

The site of Kharaib al-Dasht, located on the northern coast of Failaka, is a late Islamic settlement with an extensive fishing infrastructure. It has been excavated since 2013 by the Kuwaiti-Polish Archaeological Mission. The ceramic assemblage collected so far exceeds 18,000 fragments. The sherds underwent technological and typological analyses, which demonstrated a wide diversity of local common kitchen wares, consistent with the needs of households specialised in fishing. A considerable percentage of imported vessels was brought to Failaka from the Arabian Gulf and Persia, though Far Eastern luxury tableware was also attested. This paper demonstrates the socioeconomic role of Kharaib al-Dasht in the context of trade exchange on the microregional (Kuwait) and macroregional (the Gulf, South and Eastern Asia) scales in the eighteenth and nineteenth centuries.  相似文献

Cattle slaughter and beef consumption are barely mentioned in the literature on Chinese economic, food, or animal history. This is possibly due to the widely held popular and scholarly assumption that beef was avoided and even considered taboo in the daily diet of Chinese people in premodern times. This article investigates the tangible regulation and practice of cattle slaughter in Qing China—the period when the beef taboo was argued to be formally subsumed into Chinese morality. I ask the following questions: To what extent did the Qing state ban cattle slaughter? How was the ban enforced in the localities? Did Chinese people slaughter cattle for consumption? Were there lawful beef markets in Qing China proper? How did increasing beef-eating Western sojourners since the mid-19th century impact this sector? Accordingly, I demonstrate that with the leeway provided by the state, the cattle slaughter industry developed in many regions of China proper, especially large cities. In this sector, Chinese Muslim merchants played a dominant role, even though the Han merchants could outnumber them. Their efforts have prepared the state and Chinese merchants to better cope with new circumstances since the mid-19th century. Broadly, this paper sheds light on how different religious, ethnic, and national groups affected the economy and the practice of law in the Qing dynasty.  相似文献
