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

The paper offers a geographical interpretation of the evolving technical, political, and economic intricacy of large dams. It incorporates existing hydropolitical scholarship and the notion of the Chinese Water Machine to reframe dams as assemblages built by specific political, financial and technical processes in particular socioenvironmental regions. The paper examines the continuity of hydropolitical relationships through a genealogical inquiry into the formulation and materialisation of Ghana's three dams: the Akosombo and Kpong dams built during the Cold War, backed by Western lenders and engineering companies; and the Bui dam commissioned in the 2010s, with support from China. Based on fieldwork in Ghana and China, as well as documentary evidence, the paper argues that the thinking, planning and building of dams interconnect the host regime and external techno-financial actors with their floating political-economic interests, but in a durable way. Sometimes, even if little concrete is actually poured, the symbolic power of dams endures, transforms, and at certain times and places expands, through events and discourses of national and international interest groups pursuing their own purposes, albeit with the replacement of influential individuals and powerful institutions, and regardless of the involvement of Western, Chinese and/or other actors. Ruptures exist but do not necessarily break the continuity of dam assemblages. The emergence of an opposition assemblage that battles against dams is a more recent complexity.  相似文献

This article presents a survey of Neolithic economy, land use, trade, natural environment, and usage of plant and animal resources in central Europe, 5415–2240 B.C. (4500–1800 bc). Early, Middle A and B and Late Neolithic materials are summarized and compared. The earliest farmers expanded from southern Hungary and adjacent areas into central Europe over a relatively short time period, 100–200 years. They occupied areas only with good soils; thus probably hunters and gatherers continued to exist in many regions of central Europe. There is an increase in population and more upland areas are exploited for farming during the Middle Neolithic A and B periods. By the Middle Neolithic B period, low-level hierarchical or ranked societies appear in some regions of central Europe. The Late Neolithic may represent a modification of the mixed farming strategy observed during the earlier periods. Perhaps the herding of domestic animals became more important.  相似文献

Considerable progress has been made in recent years in the study of the Lower and Middle Paleolithic of northern Asia. There is growing evidence for initial human occupation before 700,000 years ago—as early as elsewhere in Asia—and for a very early adaptation to the arctic desert environment. New models of Lower Paleolithic settlement involve expansion and reduction of occupation in response to climatic variation, rather than simple colonization followed by steady occupation. The Middle Paleolithic of northern Asia is better documented, including actual finds of archaicHomo sapiens. The transition to the Upper Paleolithic seems to involve the survival of earlier cultural traits, but the mechanisms and processes are not well understood. Further significant knowledge concerning these periods awaits the development of common methodologies for classification and analysis.  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 article focuses on Finnish national identities because they expressed the shared experiences of newly established Finnish communities, and they were crucial in constructing a new nation. It also explores created images of the Finnish and Finland, as well as community construction in Republican China, especially after Finland gained independence in 1917. Another aim is to examine those Finnish political, cultural and economic activities that supported their identity construction in China. The specific emphasis will be on analysing the largest and sometimes cross-functioning Finnish groups in China: the governmental officials and the commercial community. By using qualitative methods, namely, discourse analysis and historical analysis, this study shows how the Finnish community created alternative, sometimes imaginative and frequently anti-imperialist national identities in the new Republican China. Indeed, by signing the Treaty Principles of Reciprocity and Equal Treatment, it was agreed that Finland and China ‘shall enjoy same rights, privileges, favours, immunities and exemptions which [might] be accorded to similar foreign agents in accordance with the principles of international law’. This article argues that Finnish aspirations were positively regarded by many Chinese, and they respected this quite unique national connection with Finland.  相似文献

In the aftermath of several decades of neoliberalism in Eastern Europe, the social fabric of post-socialist societies is frayed. In this context, nationalist cultural policies and everyday displays of national belonging have emerged as key instruments of social solidarity. There has recently been a drive of state initiatives in Latvia in the field of cultural policy aimed at strengthening national identity. In this paper, we focus our attention on one particular cultural policy initiative, Latvian Films for Latvian Centenary. Drawing on qualitative interviews with 16 film directors who participated in the Centenary film programme, the paper explores how artists and cultural operators involved in this programme are mobilised as national(ist) subjects and how they see their work within such a framework. We argue that nationalist cultural policy can be successfully implemented because the artists, themselves formed as responsible political and moral subjects in the tradition of Latvian cultural nationalism, share a regard for culture and the arts as a resource for sustaining the political statehood and the national community. However, the artists also recognise the limitations of their work as a source of social cohesion and solidarity in a society that is ethnically divided.  相似文献

In order to carry out strontium (Sr) isotope analysis, glass artefacts from South Asia were sampled with portable laser ablation (pLA), a relatively novel sampling technique that leaves damage invisible to the naked eye. Subsequently, thermal ionization mass spectrometry (TIMS) was used to obtain Sr isotope ratios after sample dissolution and separation. In this study, the goal was twofold: to determine whether the measurements of Sr isotope ratios were impacted by using a portable laser as a sample tool; and to assess the pertinence of using Sr isotope ratios to provenance Indian glass. Despite a deterioration in the precision of the measurement of the Sr isotope ratios for artefacts sampled with pLA compared with the traditional sampling method, the Sr isotope ratios of certain Indian glass are so different that this does not affect their separation but a comparison of data sets obtained using standard methods and pLA might be challenging.  相似文献

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .  相似文献
