Displacement Ductility Limits for Pile Foundations in Cohesionless Soils

The displacement ductility limit for seismic design of concrete piles is determined for the range of cohesionless soils expected in practice. The curvature ductility capacity associated with specified performance limit states, namely, the “serviceability” and “damage-control” limits, is determined based on the current provisions for confining steel. An analytical model is applied to assess the displacement ductility factor at the specified curvature ductility level. The investigated parameters include the soil stiffness, pile diameter, longitudinal reinforcement ratio, axial force level, and pile above-ground height. A set of design displacement ductility factors is recommended and verified to ensure the satisfactory seismic performance.     

The bronze artifacts from the Yejiashan site and the political presence of the Zhou dynasty in the middle Yangtze Plain: an application of lead isotope analysis

Lead isotope ratios of 15 Chinese bronze artifacts from the Yejiashan site (Suizhou City, Hubei Province) were analyzed and compared with copper ores across China. This study attempts to provide a new perspective to discuss the role that Zeng State played among all the vassal states in the early Zhou dynasty (ca. 1046–977 BC). The political presence of the Zhou dynasty in the middle Yangtze Plain is another main content of this paper. The lead isotopic characteristics of Chinese bronze artifacts between different historical periods are also in the scope of the study. By comparison, the lead isotopic ratios of the tested bronzes and copper deposits in the north Jiangxi Province show numerous overlaps. It indicates that the tested bronzes might have a single ore source, and this source was in the south of the Zhou dynasty. Combined with history and archaeological records, it is highly likely that the middle Yangtze Plain might be a part of the Zhou dynasty since the very beginning. Moreover, Zeng State might have a great influence in the ancient middle Yangtze Plain, and the nobles of Zeng State might even have authority to supervise certain area extending to Jiujiang. As lead isotopes of the bronzes appear to show a clear relation to chronology, the change of lead isotope patterns across times may further serve to distinguish the bronzes of the Western Zhou dynasty from the late Shang ones.     

基于手机数据可靠性分析的旅游城市功能空间识别研究

随着移动通信和移动互联网的普及,带有地理空间信息的“大数据”受到人文地理学者的关注。本文关注手机移动数据的旅游研究价值,以张家界市武陵源区、慈利县为例,首先分析了通信公司漫游用户数、基站网流量和话务量代表实际游客量的可靠性程度,然后探讨了漫游用户数波动对大尺度行政区的功能空间反映,最后挖掘了网流量波动对小尺度基站区的功能空间识别。结果显示,漫游用户数仅在旅游区对实际游客量具有可靠性,基站网流量比话务量的可靠性更强;漫游用户数在旅游区的波动幅度更大;基站网流量的空间因子分析识别出日常居住区、重点旅游区等功能空间。     

长株潭城市群城镇化进程与水资源利用响应关系研究

采用层次分析法与熵权法相结合的方法,构建长株潭城市群城镇化综合发展水平和水资源开发利用综合潜力评价指标体系及响应关系模型,对2001-2015年间研究区域城镇化发展进程与水资源利用之间的动态过程进行定量研究,分析主要影响因素、变化特征以及两者响应特征。结果表明：长株潭城市群处于快速城镇化和规模扩张阶段,人口城镇化和空间城镇化水平高于经济城镇化和社会城镇化水平,城镇化发展质量有待提升;区域用水负荷逐年增加,虽然水资源利用效率和管理水平稳步提升,但水资源自然禀赋和开发利用程度受区域水文条件的影响显著。在2001、2005、2007、2009、2011年,长株潭区域城镇化的发展在一定程度上受到水资源系统的约束。协调好城镇化与水资源之间的关系,必须改变规模外延扩张模式,以控制水资源总量、有效提高水资源利用效率为目标,减弱水资源系统对城镇化发展的制约,提高水资源保障能力。

热带海岛型目的地情境下旅游者地方依恋：心理归因及其形成机理

地方依恋是国内外研究热点，但热带海岛型目的地情境下旅游者地方依恋的心理归因及其形成机理未被系统考察。选取海南岛的重游型及同质偏好型旅游者的网络游记为文本分析资料，基于扎根理论构建旅游者地方依恋整合模型。结果表明：①地方心理认知、地方情感象征、地方依恋倾向是旅游者地方依恋的心理归因，构成地方依恋的“认知—情感—行为倾向”概念模型；②由心理归因的内部响应路径与个体影响因素的外部调节路径构成的“响应—调节”系统机制是旅游者地方依恋的形成机理。具体来看，地方心理认知、地方情感象征、地方依恋倾向三个心理归因的响应顺序，构成了类比学习机制、刺激反应机制和符号消费机制三种典型层级。     

论坚持马克思主义在意识形态领域的指导地位

意识形态工作是党的一项极端重要的工作,事关党的前途命运、国家长治久安和中华民族的凝聚力与向心力。A中共十九届四中全会通过的《决定》,首次把“坚持马克思主义在意识形态领域指导地位”明确为一项根本制度。B这一根本制度根源于马克思主义科学揭示人类社会发展规律,集中反映了党在中国革命、建设和改革中发展社会主义先进文化的前进方向、发展道路与基本经验,是建设具有强大凝聚力和引领力的社会主义意识形态、巩固党和人民共同思想基础的根本政治前提、制度基础与保障。     

Ostracods of the Late Devonian Frasnian/Famennian transition from Western Junggar,Xinjiang, NW China

Song, J., Crasquin, S. & Gong, Y., September 2016. Ostracods of the Late Devonian Frasnian/Famennian transition from western Junggar, Xinjiang, NW China. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Ostracods are described for the first time from the Late Devonian of western Junggar in Xinjiang, NW China. Fifty-two species belonging to 30 genera are recognized, and seven are new: Arcuaria hebukesarensis sp. nov., Bairdia shaerbuertiensis sp. nov., Cribroconcha honggulelengensis sp. nov., Microchelinella bulongourensis sp. nov., M. hoxtolgayensis sp. nov., Pribylites wulankeshunensis sp. nov. and P. junggarensis sp. nov. The ostracod fauna indicates a probable late Frasnian age for the lower member of the Hongguleleng Formation, and the Frasnian/Famennian boundary may exist in the basal part of the formation. The ostracod assemblages are referable to the Eifelian Mega-Assemblage, incorporating both the palaeocopid and smooth-podocopid associations. The fauna implies deposition in a nearshore–offshore environment during a transgression when the lower member of the Hongguleleng Formation was being deposited in western Junggar.

反思与重构:遗产、博物馆再审视——劳拉简·史密斯教授专访

随着批评遗产研究的兴起,国际学界对遗产、博物馆实践进行了深刻的反思.澳大利亚国立大学劳拉简·史密斯教授认为,考古学家和其他学科的专家都需要重新审视自己在遗产实践中的角色及其学术话语带来的政治影响,倾听社区和其他利益相关者的声音;博物馆工作也应寻求与相关利益群体更深层的互动,认识到参观者往往有着复杂的身份认同与情感诉求,避免将之视为简单的被教育对象,要为他们提供激发情感共鸣和自我反思的资源;描述和探讨不同文化语境中的遗产话语是迫切需要的研究课题,亚洲的遗产活动和思维对于遗产的多样性发展具有重要意义,批评遗产研究的"批评"概念需要多元文化思考,遗产理论发展和遗产学专业教育也需要对遗产的多元化理解.
