The History of African Village Chickens: an Archaeological and Molecular Perspective

The history of the introduction and dispersal of village chickens across the African continent is a subject of intense debate and speculation among scholars. Here, we synthesize and summarise the current scientific genetic and nongenetic knowledge in relation to the history of the species on the continent. Sociocultural, linguistic, archaeological and historic data all suggest a complex history for the species in Africa, characterized by multiple maritime and/or terrestrial introductions over time and several dispersal routes towards and within Africa. Molecular genetics information supports these observations and in addition suggests possible Asian centers of origin for African domestic chickens, including South Asia and Island Southeast Asia. However, both sets of data were until now too limited in their geographic scope, both within Africa and in comparison with chickens from Asia, to unravel the history of the species in detail. We anticipate that further continent-wide studies combining archaeological, ancient and/or modern genetic information may shed new insights on the history of the species. These will contribute to a deeper understanding of the history of trading networks and human interactions within Africa and between African and Asian societies, at the root of the development and expansion of African civilizations.     

清代垦殖政策与陕北长城外的生态环境

陕北长城外地区位于蒙陕农牧交错带,属于典型的脆弱生境地带。清代中央和地方两级政府针对当地汉民承租蒙民土地从事农牧业生产这一环节,在不同时期制定了不同的垦殖政策,经历了封禁、招垦、禁垦、拓垦四个阶段,这既是清政府对陕北长城外地区逐步认识和开发的过程,同时也是该地区生态环境变化的过程。在政策—人—环境相互作用的关系过程中,制度、政策与权力的结合对区域环境变化的影响具有根本性的驱动作用。     

中国共产党人对马克思主义中国化的理论贡献

中国共产党90年的历史,就是不断推进马克思主义中国化的历史。党的几代领导集体把马克思主义普遍真理同中国革命、建设和改革实际相结合,实现了马克思主义中国化两次历史性飞跃,形成了毛泽东思想和中国特色社会主义理论体系两大理论成果,推进了马克思主义中国化的理论创新。     

西安市汉长安城长乐宫六号建筑遗址

2005～2006年,中国社会科学院考古研究所汉长安城工作队对长乐宫六号宫殿遗址的主体建筑及其附属建筑进行了发掘。附属建筑分两部分,均由殿堂、廊道、散水和院落组成。从出土遗物看,该建筑始建于西汉初期并一直沿用到王莽时期。根据发掘资料并结合文献记载,六号宫殿遗址应是长乐宫的前殿旧址。     

Seismic Rotational Displacements of Gravity Quay Walls Considering Excess Pore Pressure in Backfill Soils

The effect of excess pore pressure developed in backfill soil during earthquake is an important consideration in rotational displacement prediction of gravity quay walls. Based on Newmark’s sliding block concept and stress-based excess pore pressure model, a new method is proposed to predict the critical rotational acceleration and angular acceleration time histories considering the development process of excess pore pressure in earthquake events. Then, the rotational displacement of gravity quay walls is predicted according to the calculated angular acceleration time histories. By using the proposed method, the effects of various parameters involved in the calculation have been studied by carrying out a parameter study. Analysis results reveal that the influence of excess pore pressure on the rotational displacement of gravity quay walls with saturated backfill soil is significant, so, can not be ignored; and rotational displacement is sensitive to the magnitude of earthquake, horizontal and vertical seismic accelerations of ground motion, wall and soil friction angle, and soil relative density. When the rotation and sliding of wall occur simultaneously, rotation and sliding will be inhibited by each other.     

甲骨文“瓠”“瓢”“卣”考辨

甲骨文■三种形体不同之字,前辈学者考释其为卣字的繁简之异。然三字所从文字偏旁有异,在甲骨卜辞中的语境和用法完全不同,说明这是三个有相互关联、而字义完全不同之字。把三字所从■偏旁与自然界实物对比后发现,■尽管形态有异,但它是匏(匏、葫芦)的象形文字。从瓠从皿的■字,是葫芦瓢漂在盛水器皿中之形,它是瓢的会意字。从瓠从倒立庐形的■字,殷商时期其材质由木质转变为青铜,盛放专用鬯酒,是为卣字。对瓠、瓢、卣三字的考订,证实了文字形体的细微差异与甲骨文字义关系密切的观点。     

基于Amos的环境地方性与游客地方感之间的关系机理分析——以西安大明宫国家考古遗址公园为例

本文以西安大明宫国家考古遗址公园为例,基于空间形态要素、公园景观要素、服务配套要素、地方性、地方感5个潜在变量,构建地方性与地方感之间的因果关系结构方程模型.通过预设观测变量因子设计量表,发放200份调查问卷,回收181份有效问卷,再运用SPSS建立有效分析数据库,并基于Amos7.0平台进行结构方程模型的验证性分析,从而探讨大明宫国家考古遗址公园空间环境营造的地方性特征与游客地方感之间的关系路径及运行机理.     

从壁画砖看南京西善桥宫山墓的年代

从南京西善桥宫山南朝"竹林七贤与荣启期"大型拼镶砖印壁画墓出土壁画砖的砖面标记文字、砖的拼装方法以及砖的尺寸规格等方面来看,该墓的年代应该在丹阳金家村墓和吴家村墓之前。一向被认为是陈朝墓的西善桥罐子山墓也应该与此墓年代相仿。     

关于中小型汉墓研究的思考

随着中小型汉墓资料的日益丰富,其研究思路和体系需要拓展和创新。研究广度方面,汉墓的分区研究需要完善,要用更广阔的视野进行对比研究;研究高度方面,需要对中小型汉墓进一步解读,上升至对社会制度和历史发展规律的探讨;研究深度方面,对中小型汉墓的研究需更加细致化,科技分析方法要更多地应用其中。
