以选民范围急剧扩大为主要的直接由来,中、西欧国家政治在19世纪末至20世纪初年普遍转变为现代大众政治。与此相伴,公众舆论对国家对外政策的影响变得显和频繁;各类(特别是殖民、经济和军事三类)利益集团积极干预甚至操纵对外政策的形成;很大程度上植根于大众非理性情感、并且多半由大众传媒表述和助长的极端民族主义和帝国主义则构成欧洲及世界政治中的一大恶性力量。总之,现代大众政治的兴起是欧洲传统外交和国际政治变更的一项重要原因。  相似文献

Ceramic production, exchange and consumption in the Banda area, west central Ghana has been affected by historical developments ranging from recent competition with alternative vessels (made of metal and plastic) to political economic upheavals that altered community relationships within and outside the region. In this study, we explore spatial and temporal patterning in pottery production, exchange and consumption using a combination of analytical techniques. Instrumental neutron activation analysis (INAA) of a large sample (491 specimens) of archaeological and ethnographic pottery, clay and temper samples from sites across the Banda area has led to the identification of seven compositional groups whose differential distribution implies shifts in resource selection through the last thousand years. Laser ablation-ICP-MS analysis was used to explore the effects of distinctive tempering agents (crushed slag) on the bulk chemical signature of a subset of Banda ceramics, while petrographic analysis provides insight into the preparation of ceramic fabrics. We integrate insights from these diverse physical studies to investigate the dynamics of pottery production, exchange and consumption over the course of the last millennium in the Banda area and explore potential linkages with broader political economic transformations.  相似文献

The present paper focuses on 85 colourless glass samples selected among the recycling cullet found in the Roman ship Iulia Felix, wrecked off the town of Grado (province of Udine, North Italy) in the first half of the 3rd century AD, with the aim of examining their chemical composition, investigating similarities within and between the three established group types (cups, plates, bottles), and comparing the chemical compositions of the Iulia Felix glass samples with groups reported in the literature for colourless glasses. Chemical analyses, performed by X-ray fluorescence and electron microprobe, indicate that the samples were all soda-lime–silica in composition, with natron as flux, according to typical Roman production technologies. Chemical data are treated by multivariate statistical tools, such as cluster analysis and the NPC test. Statistical analyses allow us to conclude that the Iulia Felix colourless glasses were produced by at least two different production technologies related to group type, confirming the trend recently identified in the literature. In addition, the trace element patterns (particularly those of Sr, Zr and Ba) suggest that beach sand with differing amounts of alkali feldspars was predominantly used as raw material, like those specifically mentioned by Pliny for glass production.  相似文献

以丝绸之路经济带暨第二亚欧大陆桥沿线的我国境内西北地区城市群为研究对象,构建城市综合竞争力指标,运用修正的引力模型、隶属度模型及潜力模型等对西北地区城市群空间联系特征进行实证分析,得出结论:伴随该区域城市群的迅速发育,城市间最短时间距离缩短,通达性大为改观;城市群城市空间联系强度水平较差,空间分异呈由东向西逐渐递减的趋势,受最短时间距离影响明显;城市群内城市受其中心城市的辐射带动作用不足;西北地区城市群潜力值整体呈东西两头好、中间凹陷的"哑铃型"状态,各城市群内城市集聚能力差异明显。  相似文献

考古发掘现场腐蚀微生物的鉴定与防治一直是考古学家和文物保护工作者面临的难点问题。截至目前,国内外对于文物出土现场微生物腐蚀信息和资料获取的研究还十分有限。本研究以山西翼城大河口西周墓地为例,探讨了考古发掘现场遗址表面腐蚀真菌的快速检测技术与可能的防治对策;通过现场直接镜检结合后期分子生物学检测技术,确定造成大河口西周墓地土遗址大量污染真菌的群落组成。研究发现,造成山西大河口墓地出土现场腐蚀的优势真菌类群主要隶属于假散囊菌属(Pseudeurotium)、链格孢属(Alternaria)和小不整球壳属(Plectosphaerella),它们分别占据了整个出土现场腐蚀真菌克隆文库中的23%、21%、和18%。竖直墓道发掘坑道内较高的温度和相对湿度以及较低的空气交换速率是造成发掘现场微生物大面积污染的主要环境因子。该研究为快速获取出土文物腐蚀微生物的群落信息提供了技术支撑,为后期腐蚀微生物的防治提供了理论依据。  相似文献

Many of the most prominent US interest groups have formal or informal relationships with Canadian groups. Yet groups in the two countries often have little incentive to share political strategies – to learn from each other. This article proposes that such learning can take place only when four factors are present: a stable relationship with governmental institutions; the resources to acquire useful political information; shared issues of concern; and a sense of being part of a well-defined cross-border region. The presence of these factors can promote the creation of enduring group networks, which in turn make cross-border political learning possible. The article presents case studies of environmental and business organizations in the New England/Atlantic Canada region to show the relationship between these determinants.  相似文献

本文通过对秦文化的考察认为,秦文化面貌在战国中期发生巨变,此前、此后器物风格迥异;秦文化的转型,证明在一定条件下,一个古代人群共同体也可以先后创造或使用两支考古学文化。这一实例,必将引发关于考古学文化与古代人群共同体关系的再思考。  相似文献

《夷坚志》是南宋文学家、史学家洪迈所编的一部志怪小说集,它虽以"鸠异崇怪"为主旨,却全面展现了宋宁宗嘉泰二年(1202)以前宋代社会的世俗百态。其间保存了大量的医药史料和医疗故事,这些故事反映了当时民众独特、复杂的医疗观念,体现了宋代医学的发展、医职群体的壮大以及民间行医队伍的庞杂,也生动地描绘了当时民众的卫生习惯与保健意识。  相似文献

This study examines whether advocacy coalitions are stable over time by examining legislative hearings data concerning U.S. foreign policy and the creation of Israel. It uses content analysis of 19 different policy core and deep core belief components applied to testimonies given in 1922 and in 1944. These belief components are used to identify members of advocacy coalitions and to test the coalitions' relative stability of membership over time. In addition, this research examines the stability of the belief systems of these advocacy coalitions. It finds that the structures of the advocacy coalitions remained relatively stable, yet new components of policy core beliefs emerged among all three advocacy coalitions, and such components are converging toward the belief system of the coalition advocating for the creation of Israel.  相似文献

Abstract

This review article investigates the state and development of overseas Chinese studies, in both its global and South African context. It points to the common difficulties related to research in this field and indicates how these have been addressed. It argues that only since the latter half of the twentieth century, both the reading population and publishers in South Africa, have become more receptive to the voice of the ‘other’. While comparatively little work has been published on the Chinese in South Africa, the three major works that have appeared reflect on a little known but integral part of our multicultural society. A brief outline of the range of work done on this topic provides the context for a closer assessment of the most recently published sociological study.  相似文献
