Micro-CT-assisted determination of the shattering and non-shattering phenotypes of charred rice spikelet bases from archaeological sites: a new methodological approach

The selection of a non-shattering phenotype is a pivotal change in the process of rice domestication. However, current research is heavily restricted by the preservation conditions of macro-plant remains in early and middle Neolithic sites, as very limited well-preserved rice spikelet bases could be retrieved. We present a non-destructive method based on micro-computed tomographic (CT) scanning, which could provide detailed visualization of the internal structures of charred spikelet bases and efficiently discriminate the shattering and non-shattering phenotypes of rice spikelet bases according to the abundance of fusiform echinate phytoliths. It could be widely applied in different contexts, especially those poorly preserved specimens and tempers in pottery sherds, greatly improving our knowledge of rice domestication.     

济贫与规训:16世纪英国社会转型时期的布赖德威尔

布赖德威尔(感化院)在英国社会转型进程中发挥了重要作用。英国布赖德威尔体系的形成经历了城市试验与国家推广两个阶段,是地方创造力与中央意志力合力的结果。布赖德威尔具有公共雇佣和规训惩罚等多重功能。围绕功能的定位,布赖德威尔的性质有一个从雇佣机构向规训机构的明显变迁,这反映出理想与现实之间的纠结和平衡。     

Reconnaissance Report on Geotechnical Engineering Aspect of the 2015 Gorkha,Nepal, Earthquake

An earthquake of moment magnitude M_w 7.8 struck Nepal at 06:11 UTC on April 25, 2015. Field reconnaissance focused on the geotechnical engineering aspect of the earthquake was carried out in the Kathmandu Valley and regions near the epicenter. This paper presents briefly the geology of Nepal, the accelerogram, and results of standard penetration tests at selected sites in the valley. The study shows the failure case histories including landslides, road embankment settlement, bridge foundations and abutment damage, and liquefaction. The paper also highlights the impact of local soil properties and basin and ridge effect on the severity of damage.     

明清北京通州古城研究

通州是明清时期运河北端漕运枢纽城市。随着漕运的发展,通州城池自明初以来也日益扩展和完善。本文利用文献档案、古地图、实地考察和访谈等多种研究方法研究了通州城垣、护城河以及城内街巷分布和功能区布局,并重点论述了通州城的主要职能。明清通州城的发展演变与漕运有着密切的关系,古城城垣扩展受到仓储职能的较大影响,城池巧妙地利用运河水系集城防与漕运于一体,城市职能随着漕运发展而日渐扩充和完善。明清通州古城集中反映了北京地区的运河文化,是重要的运河文化遗产地,应加以深入研究并实施保护。     

Development of Collaborative Structure Analysis (CSA) System and Its Application to Investigate Effects of Soil-Structure Interaction

In this article, a collaborative structure analysis (CSA) system is developed for integrating different finite-element simulation programs. In this system, a simulated structure is divided into multiple substructures, and the interaction between the substructures is considered. Interfaces for the commercial finite-element program ABAQUS and for an open-source framework for structure analysis, OpenSees, are developed to achieve CSA integration. The CSA system is applied to analysis of a soil-structure interaction (SSI) problem, and the effects of SSI are investigated, and the efficiency and accuracy of the system are demonstrated.     

岷江上游新石器时代的文化景观与环境动因

岷江上游位于我国西南横断山脉东缘,自然和人文地理特征鲜明,是藏彝民族走廊中最独特的一个区域。本文以岷江上游新石器时代为时间断面,从文化景观的角度,探讨文化源流、聚落建筑、生产生活、文化习俗以及文化传播等要素的呈现,并分析背后的环境机制以及景观呈现对环境的响应。

郑玄《仪礼注》训诂术语释义例刍议

郑玄作为两汉古献学的集大成,对汉代训诂学的发展起了很大的推动作用。其所《仪礼注》是汉代以来随释义的典范之作,训诂内容丰富,训诂方法也较完备。本通过全面收集整理《仅礼注》之训诂术语释义的用例,对其加以归类分析。力求较准确地反映出郑玄注《仪礼》一书所体现出来的各种训诂条例和训诂方法,使能有裨于阅读古注;并力图通过这种钩稽分析。能从总体上把握郑玄运用训诂术语简明扼要释义的方法,从而从一个侧面反映出郑玄注书的训释特色。     

以赛亚·伯林和中国法律正当化问题的一种片面性——以《中国法学向何处去》为例

对照以赛亚.伯林的多元论思想可以发现:我国法理学界对中国法律正当性问题的论证大多局限于必要论证,而不成其为一种充分论证。这种片面性论证只说明了一种主张自身的合理之处或其它理论的不足之处,未能就自身主张相较于其它主张的优越性作出进一步比较分析,因此必定欠缺说服力。《中国法学向何处去》即为此种片面性论证之典型例子。
