通过对河南焦作聂村商代晚期遗址出土的人骨进行观察、测量和数据统计分析,结果表明,聂村商代晚期墓地所出人骨的死亡年龄主要集中在中年期,颅骨种族特征与古中原类型的殷墟中小墓(2)组最近似,成年男性居民平均身高为165.41厘米。在聂村商代晚期人骨上还发现筛状眶与多孔性骨肥厚、骨性关节炎等骨骼病理,两性在龋病患齿率上存在显著差异,女性明显高于男性。  相似文献

南宋时,圣政修纂完毕后,须进呈皇帝和太上皇。在进呈过程中,宋廷制定了一套庄严肃穆而又极其烦琐的仪式。进呈皇帝之仪在皇帝和大臣处理日常政务的垂拱殿中完成。进呈给太上皇帝之仪在太上皇帝居所完成。在迎奉圣政和皇帝赴太上皇帝居所的环节中,秘书省道山堂和祥曦殿成为与进呈仪式紧密相关的空间。圣政的进呈仪式是由太上皇帝、皇帝、臣僚面向公众共同完成的两场表演,这种可视化表演具有浓厚的象征意义:对皇帝而言,是向天下臣民宣示自己总结和继承先朝的政治遗产,开启本朝的治道,并且以自身的实践教化臣民,传递"孝"的理念,倡导"孝";对臣僚而言,通过仪式表演,表达了他们致君"贤能"的愿望。圣政这种史籍的进书仪式为我们考察南宋官修史籍进书仪式提供了一个典型案例。  相似文献

大凼子墓群位于重庆市云阳县青龙街道复兴社区4组,重庆市文化遗产研究院等于2014年、2015年对该墓群进行了抢救性考古发掘,发掘面积共计805平方米,清理汉墓7座、隋墓1座、明墓3座,出土陶器、铜器、瓷器等近百件。此次发掘属三峡工程消落区发掘项目,是三峡工程文物保护工作的补充和完善。发现的东汉中晚期墓葬分布较为密集,疑似家族墓地。通过对这批墓葬的发掘为探讨这一地区东汉时期墓地选择、墓葬排列及在此基础上开展的人口规模、社会政治、经济发展状况等方面提供重要实物资料,另外墓葬中出土了完整的筒形排水管,为汉代墓葬排水系统研究提供重要实物资料。  相似文献

成都及周边地区东汉晚期墓葬中出土有一种明显为仙山造型的陶质插座,倾向于为摇钱树的树座。其整体的三山、平台、洞穴造型及其上较为丰富的人物、羽人、伏羲、女娲、西王母形象应是当时观念中以昆仑、西王母为中心的神仙信仰的表现。将其制作为专门的丧葬用品,一方面反映了当时丧葬文化中的神仙信仰成分和超越死亡的升仙愿望,另一方面也再次印证了西南地区流行的摇钱树的主要内涵应与升仙有关。  相似文献

前秦时关中氐人分布的武都是指侨置武都郡。侨置武都郡始于曹魏。曹魏为与蜀汉争夺陇右,将武都氐人迁徙至关中,并先后在小槐里和美阳设置武都郡以进行管理。西晋江统的《徙戎论》反映出此时关中武都氐聚居的地方未置武都郡。十六国初期屠各刘氏和羯族石氏先后统治关中,将大量氐羌迁往关东,因此这一时期在关中侨置武都郡缺乏现实基础。苻健立国关中后,在战略要地宝鸡附近侨置武都郡,是其氐人本位政策的体现。北魏时侨置武都郡始领县级行政单位,统治范围扩大,标志着氐人的关中化,同时它也是太武帝平定盖吴叛乱时分化关中南道氐人的重要战略举措。西魏北周立国关中后受政区滥置影响,武都郡领县减少。隋开皇间侨置武都郡在当权者废郡、保留州县的地方行政政策的影响下消失于历史舞台。  相似文献

This paper engages with the concept of territorialization through telling the story of the transformation of Chinese former Kuomintang (KMT) soldiers of Yunnanese origin and their descendants living in northern Thailand, from being opium and heroin traders and smugglers, to becoming mercenaries fighting against the Communist Party of Thailand in northern Thailand on behalf of the Thai military, to finally transforming into tea farmers and traders through receiving development aid support provided from the Republic of China (Taiwan). Taiwan's development aid was ostensibly only for humanitarian purposes, but in reality also had important underlying political objectives. We argue territorialization is a more-than-human political technology. In particular, it is argued that territorialization frequently combines both military politics and development politics, even though the literature often separates these two elements, as if they are not frequently intertwined and interrelated. Here, we show how these two forms of politics, one explicit and one much less so, can come together to create new social and economic realities, ones with important geographical and geopolitical implications.  相似文献

In this paper, I suggest that the category of ‘ward,’ a designation used for Aboriginal Australians in the 1950s and 1960s, has re-emerged in contemporary Northern Territory (NT) life. Wardship represents an in-between status, neither citizens nor non-citizens, but rather an anticipatory citizenship formation constructed by the Australian state. The ward is a not-yet citizen, and the deeds, acts, and discourses that define the ward's capacities to act as a political subject can maintain their anticipatory nature even as people ‘achieve’ formal citizenship. Wardship can be layered on top of citizen and non-citizen status alike. Rather than accounting for the grey areas between ‘citizen’ and ‘non-citizen,’ therefore, wards exist beyond this theoretical continuum, demanding a more nuanced accounting of political subjectivities and people's relationships to the state.I trace the emergence of the category ‘ward’ in the 1950s and 1960s in Australia and its re-emergence for Aboriginal Australians impacted by the 2007 Northern Territory Emergency Response legislation. The promise of citizenship offered by the status of ‘ward’ is built upon expectations about family life, economic activity, and appropriate behaviour. These assumptions underscore an implicit bargain between individuals and the state, that neoliberalised self-discipline will lead to both formal citizenship rights and a sense of belonging. Built-in impediments, however, ensure that this bargain is difficult, if not impossible, to fulfil.  相似文献

古建筑三维重建已成为历史遗迹保护与修复的重要内容。为了探讨三维激光扫描数据的获取流程、数据处理方法,以三维激光扫描获取的大雁塔海量点云数据为例,研究了古建筑三维重建中点云数据获取与处理的详细过程。联合Cyclone、AutoCAD和3D-Max软件的优点构建了大雁塔真实的横面、剖面、立面模型,其中重点研究了海量点云数据在Cyclone软件中分块建模的方法。结果表明:将拼接好的大雁塔海量点云数据分块建模,不仅加快了数据处理的速度,而且符合精度要求。在点云数据拼接时采用标靶拼接和同名点拼接相结合及测站间两两拼接之后再整体拟合平差的方法,减少了拼接中的误差,使每站拼接误差都不超过3cm。在建模过程中的墙体拟合是上万个点云经过平差计算得到,精度高达2mm。最后在3D-Max软件中组合、渲染和贴图,真实地构建了大雁塔三维立体模型。为古建筑数字化存档和后期的修缮工作提供了重要的依据。  相似文献

Federalism often creates additional decisions for interest groups in determining how best to advocate for their policy recommendations in the legislative process. Should they focus their advocacy at the local, state, or national level of government? This article examines interest group behaviors in water quality policy in the Great Lakes region from 1960 to 2000. I evaluate the reasons for interest group decisions about which level of government to target, using historical analysis of Great Lakes water quality policy in the United States and Canada. The results of this analysis show that in many cases groups are influenced in their decision-making based on the level of government that has the greatest jurisdiction over the policy, supporting a neoinstitutional argument.  相似文献

This paper presents the findings arising from neutron activation analysis (NAA) of northern Chilean domestic ceramic samples from Caleta Vitor (n = 38) and clay samples (n = 15) from nearby valley, coast and highland contexts. This study presents the first NAA data set of ceramics spanning a temporal period of 1500 years (c.2000 to c.476 bp ) from the Vitor Valley as well as the first attempt to use NAA to characterize potential clay sources in the region. On the basis of this study, we argue that the majority of domestic ceramics from Caleta Vitor share compositional similarities with clay samples collected from nearby valleys, allowing us to infer that the Caleta Vitor populations primarily procured their clay for domestic ceramics from local sources throughout a 1500‐year period. Thus, despite the fact that there were inter‐regional interactions during this period that included the influence of powerful Andean polities, it would appear that domestic ceramics continued to be produced locally, and by implication it can be argued that such interactions did not substantially affect this sphere of material culture production. Further, the apparent continuities in domestic ceramic production allow us to reflect on local decision‐making processes throughout the cultural phases considered in this research.  相似文献
