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

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

青海大通县出土汉代玻璃的研究 总被引:1,自引:0,他引:1
本文共对12件玻璃样品进行化学组成分析.其中,部分样品还进行了密度测定,X 射线衍射分析和显微镜观察.此外,还对一颗黄色玻璃珠的表面层进行 SEM-EDX 分析.结果表明,该玻璃珠表面有金箔涂层.根据分析结果,青海大通县出土玻璃的基础成分可归为三类,即铅钡玻璃(Na_2O-PbO-BaO-SiO_2系统玻璃),钠钙玻璃和钾硅玻璃(K_2O-SiO_2系统)。此外,还对玻璃的来源进行了探讨. 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

明人追求通过修谱与祠祭表达祖先崇拜和宗族共同体的意识。明人的祖先祭祀,依据祭祖地点,可以划分为墓祭、家祭、祠祭。娄坚《徐氏宗谱序》分析了明代江南故家大族与谱牒不盛的问题,认为吴人不能聚族在于习俗的鄙、奢所造成的,强调通过宗族建设移风易俗。明代族谱更加盛行,表现出强烈的以谱法接济宗法的观念。苏州士大夫发扬光大了宋代范仲淹设置义田、义庄的传统,以此赡族进行宗族建设,官府倡导并保护义田与义庄,形成了不同于其他地区宗族形态的特色。明代苏州处于宗族组织化的新阶段。 相似文献

部落构成了中东社会生活的一个重要层面,是理解中东国家必不可少的视角。1953年,法国在摩洛哥发动政变,废黜了支持民族主义力量的苏丹穆罕默德五世。格拉维部落在此期间经历了兴衰起落。此次政变集中反映了摩洛哥国内部落和民族主义力量对国家政权的竞逐,是观察中东地区部落和国家间复杂逻辑关系的典型个案。摩洛哥传统势力的代表格拉维部落与国家间关系表现出复杂形态:部落利用国家力量实现崛起,部落对抗民族主义力量发动政变企图控制国家,最后部落被国家抛弃而衰落。在部落和民族主义竞逐国家政权的过程中,法国殖民者成为二者沉浮的决定性因素和制衡力量。由于部落对国家认同的脆弱性,殖民主义政权得以通过玩弄部落认同对殖民地进行分而治之。 相似文献
