余家寨遗址位于湖北麻城市,面积8300平方米。1991年,麻城市修建106国道将余家寨遗址西部边缘破坏,省、市、县文物部门对该遗址进行了全面调查勘探。遗址包含有新石器时代和西周两个时代的文化堆积。新石器时代标本中的主体是石家河文化,还兼有屈家岭文化、薛家岗文化及樊城堆文化等多种文化因素。在新石器时代遗址之上筑有一座面积约15000平方米的西周城堡,夯土城墙及护城河大部分保存完整。余家寨遗址为研究长江中下游原始文化之间的关系及南方商周文化与中原商周文化的关系提供了重要资料。 相似文献

汉代郡治之县,在同郡属县中秩级最高。由张家山汉简《二年律令·秩律》载录的各郡辖县秩级,可探知西汉初年某些郡的治所: 陇西郡治所为上邽县;上郡治所为高奴县;北地郡治所为彭阳县。此外,西汉初年汉中、河东、河内三郡治所也可以凭借《秩律》得到进一步限定。《秩律》在西汉初年郡治研究上的价值需要得到重视。 相似文献

建国初期"联苏抗美"的国防战略是"一边倒"外交战略的延伸,但不能将两者混淆。"一边倒"外交战略着眼点在于社会制度的一致和意识形态的价值取向,"联苏抗美"的国防战略着眼于国家安全和国防巩固,它的提出既有历史经验的因素,更取决于新中国国家安全环境;它经受了历史的检验,证明是一个符合当时新中国国家安全利益的正确的决策,应给予充分的肯定。 相似文献

西安理工大学汉墓壁画人物服饰辨析 总被引:1,自引:0,他引:1
通过对西安理工大学西汉壁画墓人物服饰、服色及人物发式进行探讨,认为西汉晚期长安城内的中下级官吏在日常生活中并不总是戴着标志身份地位的冠,仅裹帻巾甚至只盘发髻,所穿上衣主要为袍、襦,颜色以青、红和浅灰为主,下裳多穿大裤,颜色多为白色,男女服色差别不大,均以青、红和浅灰为主,男性多主鲜艳的红色,其次为青色,女性以青色为多,红色则相对较少。男子发式相对较为简单,在头顶梳一圆髻或扁平髻,女性流行高髻,有的在高大髻上插笄,笄之一端饰以垂梢。 相似文献

The biocultural effects of European contact varied considerably throughout the Americas. Some populations were decimated by colonialism, while others benefited from trade relationships and access to new technologies. It has been suggested that initial contact with European fur traders and explorers was economically favourable for Plains village populations, thereby facilitating a period of cultural florescence. In this study, we evaluate the hypothesis that Plains groups were better off than their predecessors during the initial contact period by comparing frequencies of enamel hypoplasia, cribra orbitalia, and porotic hyperostosis in pre‐ and post‐contact Arikara skeletal assemblages. We included both juveniles and adults in our sample to capture variation in the stress experience of different segments of the population. Our analysis revealed similarly low frequencies of cribra orbitalia in the pre‐ and post‐contact groups and no observed cases of porotic hyperostosis. Enamel hypoplasia, however, was significantly more prevalent among post‐contact Arikara villagers when compared to their pre‐contact counterparts, which suggests that stress levels were higher after European contact. Additionally, enamel hypoplasia was most common among post‐contact juveniles. The elevated frequency of enamel hypoplasia in the post‐contact sample combined with the low frequencies of cribra orbitalia and porotic hyperostosis suggests that disease stress, rather than nutritional deficiencies, was likely responsible for the decline in overall health following European contact. These results also suggest that juveniles are sensitive indicators of systemic stress within a population and should be included in bioarchaeological analyses of prehistoric health when available.

The term avian osteopetrosis is used to describe alterations to the skeletal elements of several species of domestic bird, most typically the chicken, Gallus gallus domesticus (L. 1758). Such lesions are routinely identified in animal bones from archaeological sites due to their distinctive appearance, which is characterised by proliferative diaphyseal thickening. These lesions are relatively uncomplicated for specialists to differentially diagnose and are caused by a range of avian leucosis viruses in a series of subgroups. Only some avian leucosis viruses cause the development of such characteristic lesions in osteological tissue. Viraemia is necessary for the formation of skeletal pathology, and avian osteopetrosis lesions affect skeletal elements at different rates. Lesion expression differs by the age and sex of the infected individual, and environmental conditions have an impact on the prevalence of avian leucosis viruses in poultry flocks. These factors have implications for the ways in which diagnosed instances of avian osteopetrosis in archaeological assemblages are interpreted. By integrating veterinary research with archaeological evidence for the presence of avian leucosis viruses across Western Europe, this paper discusses the nature of these pathogens, outlines criteria for differential diagnosis, and offers a fresh perspective on the human‐aided movement of animal disease in the past through investigation of the incidence and geographic distribution of avian osteopetrosis lesions from the first century BC to the post‐medieval period. © 2017 The Authors International Journal of Osteoarchaeology Published by John Wiley & Sons Ltd. 相似文献

This article offers a critical account of Spanish high-speed rail (HSR) through the lens of the spatial fix. I designate the integration of Spanish HSR into a European-wide process of circulation of finance capital as the HSR-finance complex. The analysis of the inner workings of the HSR-finance complex reveals the way in which European finance has laid the conditions of possibility for the development of the project and offers a forewarning about the dangers of leveraging finance capital toward green infrastructure. The analysis of the Spanish HSR-finance complex shows that the particular form of capital circulation that has made it possible has not brought about new productive combinations but has instead deepened traditional relations of economic dependency and magnified their socioenvironmental consequences. 相似文献

中俄交往始于蒙古西征和金帐汗国时代(1238-1480年),中国学人撰写俄国史自1878年刊印的鹭江奇迹人的《俄国志略》,到今天已经有整整140年的历史。中国的俄国史学科伴随民族命运、国家危机以及世界形势的变化而生,自诞生之日起即负有学人情怀、民族重任和学术职责三重使命。因此,俄国史学科在中国一直发挥着“知夷”和“盗火”的两大作用。中华人民共和国成立后,俄国史(包括苏联时期和俄罗斯联邦时期)研究获得了70年的巨大发展,主要成就有:1985年中国苏联东欧史研究会成立(1992年英文更名为中国俄罗斯东欧中亚史研究会),高等院校、社会科学院、党校、国家有关部委及党政机构纷纷设立俄国史或俄罗斯问题研究机构,建立了从历史学学士、俄国史硕士到俄国史博士的三级专业人才培养体系,俄国史和俄罗斯问题研究的专业期刊创立并连续出版,大量的俄国通史、中俄(中苏)关系史、专题著作、各类教科书、翻译著作(来自俄文、英法、法文、德文、波兰文等)出版,中国俄国史学者积极参与国际学术会议和国际合作研究,具有中国特色的中国“俄罗斯学”新学科正在建立过程中。 相似文献
