WOLFGANG KEMPF 《Reviews in Anthropology》2013,42(4):217-238
Global climate change and its consequences for humankind opens up a research field for exploring the diverse dimensions and forces of change through time. Chief among the objects of inquiry is how climatic shifts impact on ecological and social structures and developments and what human agencies are able to unfold under given conditions. Conclusions from such reciprocities can help to deliver a differentiated approach to the inroads of anthropogenic climate change. Central to this enterprise are such analytic perspectives as the discipline of anthropology can bring to researching the impact of climate change on human societies. 相似文献

How does major policy change come about? This article identifies and rectifies weaknesses in the conceptualization of innovative policy change in the Advocacy Coalition Framework. In a case study of policy belief change preceding an innovative reform in the German subsystem of old‐age security, important new aspects of major policy change are carved out. In particular, the analysis traces a transition from one single hegemonic advocacy coalition to another stable coalition, with a transition phase between the two equilibria. The transition phase is characterized (i) by a bipolarization of policy beliefs in the subsystem and (ii) by state actors with shifting coalition memberships due to policy learning across coalitions or due to executive turnover. Apparently, there are subsystems with specific characteristics (presumably redistributive rather than regulative subsystems) in which one hegemonic coalition is the default, or the “normal state.” In these subsystems, polarization and shifting coalition memberships seem to interact to produce coalition turnover and major policy change. The case study is based on discourse network analysis, a combination of qualitative content analysis and social network analysis, which provides an intertemporal measurement of advocacy coalition realignment at the level of policy beliefs in a subsystem. 相似文献

Research on media framing of policy issues has flourished. Yet the varied approaches to conceptualizing and operationalizing issue frames that make this literature rich also hinder its advancement. Here, we document the benefits of a two‐tiered method: the first level accounts for issue‐specific frames, while the second level tracks frames that generalize across issues. For this study, we draw on generalizable frames from prospect theory (loss vs. gain frames) and social identity theory (self‐referential vs. other‐referential frames). We discuss the theoretical merits of a two‐tiered approach, arguing that it should yield compound insights greater than the sum of its parts. Applying this method to newspaper coverage of the war on terror, we find a strong trend at the generalizable level: media framing of the war shifted over time from a predominant use of “fear” (self‐referential loss) frames to an increasing use of “charity” (other‐referential gain) frames. Our approach further reveals that the fear frames used in the lead‐up to the Iraq War were not driven by issue‐specific frames related to terrorism or weapons of mass destruction as we might have thought, but rather by frames related to the anticipated threats to U.S. troops. This study sharpens our understanding of how framing of the war evolved, but more broadly it suggests that a two‐tiered approach could be applied both within and across policy issues to advance our understanding of the framing process. 相似文献

This paper looks at two figures in the modern, European, eighteenth-century debate on luxury. It claims to better understand the differences between Francis Hutcheson and Bernard Mandeville by exploring how Hutcheson treated the topic of luxury as a distinction between two desires, thus differing from Mandeville's concept of luxury, and a concept of temperance based on moral sense. It explores why Hutcheson believed that luxury was a moral, social and political issue and particularly why he considered Mandeville the embodiment of a threat that went beyond simple considerations of the content of The Fable of the Bees to touch on reflections on the equilibrium of a social and political system. It aims to show how the psychological and the moral dimension were connected to Hutcheson's political theory and how luxury was one of the key points of this connection. 相似文献

The Early to Middle Bronze Age transition in Northern Mesopotamia has received great attention for the apparent concurrence of aridification, deurbanisation, and the end of the Akkadian empire around 2200 BCE. Our understanding of the “crisis” has been almost exclusively shaped by ceramics, demography, and subsistence. Exchange and the associated social networks have been largely neglected. Here we report our sourcing results for 97 obsidian artefacts from Urkesh, a large urban settlement inhabited throughout the crisis. Before the crisis, six obsidian sources located in Eastern Anatolia are represented among the artefacts. Such a diversity of Eastern Anatolian obsidians at one site is hitherto unknown in Mesopotamia. It implies Urkesh was a cosmopolitan city with diverse visitors or visitors with diverse itineraries. During this crisis, however, obsidians came from only two of the closest sources. Two to three centuries passed before varied obsidians reappeared. Even when an obsidian source reappears, the raw material seems to have come from a different collection spot. We discuss the likely exchange mechanisms and related social networks responsible for the arrival of obsidians at Urkesh and how they might have changed in response to climatic perturbations and regional government collapse. 相似文献

气候对中国古代塔砖材料性能劣化影响的研究 总被引:2,自引:1,他引:1
在气候影响下,塔砖材料性能的劣化加剧了中国古塔结构的损伤,减少了古塔的结构寿命。为此,课题选择两个极具代表性的中国古代砖塔—1500年历史的嵩岳寺塔和1200年历史的法王寺塔进行同一性研究,欲证明两塔在地理位置、环境气候、形制、塔体古砖制造原料和制造工艺等方面均具有很强的相似性和同一性。采用X射线荧光光谱法分析了两塔塔砖的材料成分,采用压汞法对两塔塔砖材料的孔隙率、孔隙结构和孔隙分布特征进行了实验。两塔塔砖材料实验结果的差异证明:在公元5世纪到公元8世纪的300年气候影响下(该气候为自然营力而非实验室人工模拟),塔砖材料孔隙率的增大是导致中国古代塔砖性能劣化的主要原因,大约30%左右的孔隙从小于1000nm孔径发展扩大到10000~50000nm孔径是塔砖材料孔隙率增大的主要表现形式。因此,预防小孔径孔隙(小于1000nm)在气候影响下发展扩大的防治措施应该成为中国古代砖塔保护工作的研究重点。同时,对因塔砖材料性能劣化而产生的古塔塔体的表观特征进行了分析,分析结果有利于中国古代砖塔的保护。 相似文献

The 30-year story of the geography department at Oxford Brookes University is presented as an oral history in the words of the experienced full-time staff. The department has gained a reputation in the UK and beyond for innovative active-learning methods and its story is an example of how a pedagogic culture can develop in a geography department. The story can also be read as a case study of a workplace in higher education, or as a contribution to the history of education. Most importantly, though, it offers insight into the key factors concerning the development of innovative teaching practice. 相似文献

“以禅喻诗”是一种经验性的类比思维,“禅”与“诗”都是复杂的范畴,难以笼统论之。前者涉及禅语、禅法、禅理、禅趣、禅宗有关宗派、参禅的活动(态度、方法等)、禅家之妙谛和禅宗公案故事等;而后者则涉及诗人、诗派、作品、读者四大方面,进而包容构思、写作、赏析和评论等活动。”所谓“喻”则取譬喻之意,表现为一种通过将“禅”与“诗”进行类比,最后诉诸于“诗”的思维方式。本文主要分“何以以禅论诗”、“何为以禅喻诗”、“如何以禅喻诗”和“从《沧浪诗话》看以禅喻诗”四个部分,分析了“以禅喻诗”的存在原因、意义内涵、思维方法和在严羽《沧浪诗话》中的具体表象,以实现对其较为全面的理解和阐释。 相似文献

宋代金石学家薛尚功著有《历代钟鼎彝器款识法帖》二十卷和《广钟鼎篆韵》七卷。《款识法帖》以摹录铭文为主,并做释文和考说,逐一对器物的制作年代进行断定,开创了后世考释类金文著作的通例。考释文字方面,基本使用了对照法、推勘法和偏旁分析法,已经能释出大部分常用金文,对金文构形特点和古文字发展的一些普遍规律也有所认识。古器物学方面,提出了器物断代的几个标准,对器物的用途也有比较准确的认识,表现出了比较高明的识见。 相似文献
