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

This paper argues for a rediscovery and reassessment of the contributions that humanistic approaches can make to critical and radical geographies. Based on an exploration of the archives of Anne Buttimer (1938–2017) and drawing upon Paulo Freire's notion of conscientização (awareness of oppression accompanied by direct action for liberation), a concept that inspired the International Dialogue Project (1977–1988), I explore Buttimer's engagement with radical geographers and geographies. My main argument is that Buttimer's notions of “dialogue” and “catalysis”, which she put into practice through international and multilingual networking, should be viewed as theory‐praxes in a relational and Freirean sense. In extending and putting critically in communication literature on radical pedagogies, transnational feminism and the “limits to dialogue”, this paper discusses Buttimer's unpublished correspondence with geographers such as David Harvey, William Bunge, Myrna Breitbart, Milton Santos and others, and her engagement with radical geographical traditions like anarchism, repositioning “humanism” vis‐à‐vis the fields of critical and radical geography. 相似文献

This article compares and contrasts the approaches of the NewDeal Federal Writers' Project and the Columbia Oral HistoryProgram in an effort to reconsider the paradoxical history oforal history research in the United States and its relationshipto how many oral historians today look at their work and thehistory of their field. As it turns out, the theoretical andsocial concerns of the FWP projects are closer to current theoreticalconcerns of oral historians than the work Allan Nevins conductedin the early years of the Columbia project. The article alsoshows how awareness of the history of the intellectual and culturalcurrents that affect oral history projects in general, and theFWP's work in particular—interviews with former slaves,tenant farmers, industrial workers, and members of ethnic minorities—canhelp us analyze and use those materials. It argues that an awarenessof continuity and discontinuity in the history of oral historymakes it possible for today's oral historians to have a productivedialogue with their predecessors in the field. 相似文献

One of the most important phases of case‐oriented research is identifying the relevant population of cases. The best practice scheme suggests first identifying the positive and then the negative cases, based on the assumption that the population is small and known. This scheme is inapplicable when the population is unknown, as is the case with many public administration and public policy outcomes, which are often less visible. However, most research either ignores this difficulty or recommends a single case study. This article suggests that when the population is unknown scholars can apply the possibility principle to identify the relevant population of cases. In order to do so, a large dataset is required. In policy studies, the Comparative Agendas Project (CAP) can serve this aim. This article highlights CAP's applicability for case selection based on the possibility principle in two less visible policy outcomes: conversion and drift. In that, it not only addresses an overlooked challenge but also promotes both CAP as a useful tool for qualitative researchers and the expansion of comparative work on conversion and drift. 相似文献

21世纪以来,中国考古学呈现出新的学科特点和发展趋势。中国社会科学院考古研究所王巍所长认为,中国考古学随着自身的发展特别是在以"中华文明探源工程"及其各项阶段性成果的推进与影响下,形成了中国气派和中国特色,正朝着科学化、国际化、社会化、大众化的趋势和方向发展;中国考古学需要与国际考古界加强交流,博采众长,走向世界;作为一级学科的考古学的学科建设应是从文物管理机构到文物考古研究机构所共同担负的责任,需要形成一整套既符合中国实际,又顺应中国考古学发展的二级学科的设置,同时培养能够满足考古学发展需要的人才;公众考古是目前考古学新的发展走向,考古界需要转换意识和机制,培养专业人才,坚持考古的纯洁性和道德规范,以更好地服务社会与遗产保护事业。 相似文献

The value of communications skills in geographical education is briefly discussed. In particular the lack of interview and interviewing practice is noted. The use of realistic interviews as part of small-group project work has been developed at Salford over 10 years. The elements include the drafting of job and person specifications, the writing of a cv and covering letter, and the organisation and running of interview panels. Detail is given of how the whole process is assessed. Negotiation skills are also developed. An important element is the realism of the process. The principal down-side is the amount of staff time involved, but this is more than compensated for by the students' perceived value of the skills developed. 相似文献

AbstractWell preserved ancient shipwrecks are rare in the archaeological record, but when discovered, they can provide valuable information on a wide range of research issues if analyzed and documented properly. In this paper we discuss the significance, potential, and constraints of mapping methods applied during the underwater excavation of shipwreck sites with special emphasis on stratigraphy, documentation of finds, and reconstruction of site formation processes. As a case study, we present the digital photogrammetry and computer vision software programs used in the excavation of the 4th-century b.c. shipwreck at Mazotos, Cyprus. Our goal is to develop a targeted documentation and mapping method of ongoing shipwreck excavations so that others can address complex research questions concerning this unique discipline of archaeology. 相似文献
