George Woodcock was anarchism's most influential historian and an important public intellectual in Canada. This article focuses on his engagement with Canadian nationalism in the 1960s and 1970s. It argues that a ‘philosophical anarchism’ was at the heart of his intellectual project, and this informed his reading of Canadian cultural development and subsequent political challenge to Pierre Elliott Trudeau's civic nationalism. Woodcock decoupled the concepts of ‘nation’ and ‘state’ in order to develop a radically different model for Canada—the ‘anti-nation’—defined by regionalism, federalism and direct democracy. His reading of Canada's cultural history supporting this position was therefore part of a strategy to repurpose nationalist rhetoric towards anti-state ends.  相似文献

The United Arab Emirates (UAE) has sought to establish a national identity among its nationals since its inception in 1971. Contrary to the pessimism in its first few years, the UAE was able to create a national identity among its nationals despite their initially differing loyalties. The UAE has now embarked on a phase of creating a new national identity that includes non-nationals, encompassing migrants and expats. This study argues that this new identity aims to include, at least discursively, non-nationals, presenting them as an integral part of society. It should be noted that this new identity does not seek to standardize or assimilate the whole population, in contrast to the first identity, which aimed to standardize the nationals. Its primary aim is rather to express its appreciation of the migrant population through the notions of tolerance, diversity, and multiculturalism, while also preventing complaints from the nationals. This study analyses the ways of including non-nationals in a new national identity through national gatherings (national days), institutional activities (heritage festivals, cultural gatherings, cultural center visits and activities), media analyses (state-sponsored media), and foreign policy initiatives that emerged (or presented) due to domestic diversity, such as Pope's visit.  相似文献

全球化进程下,跨国移民成为不同地域间文化交流、冲突和再协商的主要载体,其在地饮食适应问题尤为凸显。本文回顾了国内外跨国移民饮食适应的研究,发现由营养学等范式主导的早期研究偏重对饮食适应水平的直接观测,较少探究饮食适应的身体属性、地方关系以及文化意涵。文化地理学视角下的跨国移民饮食适应的相关研究进展主要包括以下三个方面:身体尺度下的动态饮食适应过程、地方尺度下跨国饮食景观的生产与重构,以及身体与地方交互尺度下饮食适应与身份认同的复杂关系。本文最后针对当前研究的主要不足提出未来跨国移民饮食适应研究的可能议题。  相似文献

聚醋酸乙烯酯(PVAc)乳液是常见的彩绘类文物保护材料。采用激光粒度仪、热重/差热分析、红外光谱、X-射线衍射、扫描电镜、透射电镜等表征了PVAc乳液的粒径以及胶膜的热稳定性、结构和形貌;采用粘度计、表面张力仪、pH计、电导率仪等研究了乳液浓度与其粘度、表面张力、pH、电导率的关系;通过冻融、室温-高温放置、离心分离研究了乳液的稳定性;同时用PVAc乳液对模拟起甲和酥碱的壁画进行了修复。结果表明,PVAc乳液粒径呈双峰分布,小粒子的平均粒径为380 nm,大粒子的平均粒径为5.85μm;乳液胶膜为非结晶物质,胶膜热重的最终质量残留为1.54%,335℃出现放热峰。PVAc乳液的电导率随浓度的增大而增大,pH随浓度的增大而下降;相同温度下表面张力随浓度的增大而基本呈现低浓度下降,高浓度上升的趋势。相同浓度下,表面张力随温度升高而无显著变化,表明PVAc乳液的表面张力受温度变化影响不大。相同温度下,乳液粘度随浓度的增大而增大;相同浓度下,乳液的粘度随温度的升高而降低。冻融、离心分离和不同温度下静置发现,该乳液出现分层。用该乳液对模拟起甲和酥碱壁画修复后,再分别老化20个循环和12个循环,发现颜料层再次空鼓、起甲。综合分析,说明实验中所使用的该种PVAc稳定性和抗老化能力较弱,在修复彩绘类文物中应慎重选择PVAc的种类,综合考虑PVAc的使用浓度、环境因素对其性能的影响,以达到最佳使用效果。  相似文献

慈利白公城遗址历史悠久,具有重要的考古价值。该遗址出土了大量木质井壁及少量其他木质文物,为了解这些木材的特点,以及为木材保护提供相关的参考,通过徒手切片,并利用光学显微镜对该遗址出土的10件木质样品进行鉴定。结果表明其中1件为无患子(Sapindus. mukorossi Gaertn.),1件为冷杉(Abies fabri(Mast.)Craib),2件为湖南杨桐(Adinandra. acutifolia Hand.-Mazz.),2件为香椿(Toona sinensis A. Juss.),4件为润楠(Machilus pingii Cheng ex Yang)。通过实验结果,初步推测井壁的制作在当时是比较重要的工作,此时已经在选择性地使用木质井壁原料。从树种适宜生长的环境上看,同时期该遗址附近可能是以阔叶材为主的针阔叶混交林,气候温暖湿润。  相似文献

In recent decades, there has been a noticeable increase in the use of quantitative techniques in the study of ethnicity and nationalism, without, however, a sufficient amount of reflection on how these techniques have contributed to our understanding of ethnic and national identities. As such, in this exchange three sets of authors answer questions about the degree to which it is possible to use quantitative data to measure ethnic and national identities, which types of methods are most suitable in measuring these identities and what the major research findings of this quantitative research are that were not possible using qualitative approaches.  相似文献

A major theme of current archaeological research in the Middle Atlantic region of Eastern North America is the recognition of cultural variability across space and through time. The most significant culture change experienced during the entire time frame of regional prehistory occurred ca. 5000 B.P., when there were major changes in regional environments. Before 5000 B.P., adaptations were characterized by small groups of mobile hunters and gatherers. After 5000 B.P., there were continued growth in regional populations and increases in sedentism, intensive use of a limited range of food resources, social group size, and social complexity.  相似文献

The Pacific Coast of North America was occupied by many distinctive groups of coastal hunter-gatherers at the times of early contacts with Europeans. Despite significant cultural diversity, Pacific Coast peoples shared lifeways oriented toward generally similar marine, nearshore, littoral, and estuarine habitats. In this paper, we examine some major issues that guide much of the archaeology done along the Pacific Coast, then discuss some of the theoretical and methodological problems that limit the efficacy of archaeological reconstructions. Most archaeological research conducted on North America's Pacific Coast has been oriented toward the search for the origins and development of a variety of cultural patterns. A comparative review of California and Northwest Coast sequences provides interesting parallels and discrepancies in the approaches taken in studying some of the major issues in Pacific Coast prehistory.  相似文献

Radiocarbon Chronology of the Siberian Paleolithic   总被引:2,自引:0,他引:2  
We have compiled 462 C-14 determinations for 120 Paleolithic and Mesolithic sites from Siberia and the Russian Far East. The Mousterian sites are dated to ca. 46,000–28,500 BP. The Middle–Upper Paleolithic transition dates to ca. 43,300–28,500 BP. Although there are a few earlier sites, most of the Upper Paleolithic sites are dated to the time interval between ca. 34,000 BP and 10,000 BP. The earlier Upper Paleolithic stage is characterized by macroblade technology and is radiocarbon-dated to ca. 34,000–20,000 BP. The earliest microblade technology occurs in the late stage of the Upper Paleolithic, dated to ca. 23,000–20,000 BP, but the majority of microblade sites is dated to ca. 20,000–11,000 BP. The Final Paleolithic (Mesolithic) sites date to ca. 12,000–6000 BP. At ca. 13,000–11,000 BP, the earliest Neolithic appeared in both the Russian Far East (Amur River basin) and the Transbaikal. The Paleolithic–Neolithic transition occurred ca. 13,000–6000 BP.  相似文献
