宋代官员墓葬相关问题刍议

从现有考古材料来看,与前代相比,宋代墓葬体现的等级制度并不明显,而官员墓葬似恰是造成这一状况的原因.原本应当尊奉制度、为民表率的官员群体中,有很大一部分官员并未向下传递上层的丧葬文化,反而被出身之地或归葬之所的富裕平民阶层同化.由此使其地下墓葬部分呈现出“地方化”的特征.而这一情形,所反映的可能是两宋时期,民间经济力量...     

Ecosystemic politics: Analyzing the consequences of speaking for adjacent nature on the global stage

This article introduces a conceptual framework for analysing and comparing the broader or unintended effects of cooperation anchored in border-crossing ecosystems. The importance of addressing this lacuna in our scholarship on such sub-global cooperation is underscored by research in political geography that has demonstrated how the creation of scale is an important expression of power relations and how interaction with the materiality of different kinds of spaces necessitates distinct political technologies (and thus may have distinct effects). The article introduces three key analytical angles central to policy field studies in international sociology and demonstrates their utility through a case of the Arctic/Arctic Council. These analytical angles – networks (what are the relationships shaping the field?), hierarchies (who leads and how does leadership work?), and norms for political behavior – capture key consequences and dynamics of ecosystemic politics in a concise fashion that lends itself to cross-case comparison. The Arctic case focuses on the changing network positions and roles of non-Arctic actors over time, as an initial exploration of the broader ordering effects of such forms of cooperation. The findings suggest that most non-Arctic actors have experienced a decline in their centrality in Arctic cooperation, even as the Arctic has received intensified global interest and the number of participants in Arctic Council work has increased. Further comparative work along these lines would leave us better equipped to assess whether states speaking for their own immediate environs is better – and if so, in which ways – than seeking common solutions to global challenges.     

Evaluation of Strength Hierarchy of Beam-Column Joints of Existing RC Structures under Seismic Type Loading

To evaluate the strength hierarchy, three different types of exterior beam-column joint, i.e., gravity load designed, non ductile and ductile, following two different codes are considered. Strength of different components of beam-column joint, i.e., column, beam, and joint core, is individually calculated from different failure criteria. Shear strength of the joint is evaluated from softened strut and tie model. Strength hierarchy, ultimate strength, and critical failure modes of the specimens are analytically estimated and found to be well corroborated with the experimental results. The study will help in designing the earthquake resistant RC structures in a more rational way.

Strength Hierarchy at Reinforced Concrete Beam-Column Joints and Global Capacity

Strength hierarchy assessment is a method that can be utilized to identify the weakest structural element at a reinforced concrete (RC) beam-column joint. The method was extensively used in various research activities at the University of Canterbury, which mainly involved beam-column joint subassembly tests. However, this method required improvements and refinements in order to be adopted in multi-story building applications. In this paper, the improvements made to the method are reported. In the improved method, capacity of the weakest element at every beam-column joint in an RC frame building can be related to the corresponding global base shear demand. The method has been illustrated via two example applications: an RC frame lacking joint shear reinforcement and a modern RC frame with adequate joint shear reinforcement. The case study examples confirmed the accuracy and the effectiveness of the method.     

战国秦汉觯、卮、樽辨析

樽、卮(含觯、卮两种器物)很容易被混淆,我们通过综合传世文献、出土文献、考古出土实物三方面材料,认为觯、卮共存且器形有别,觯附三足,卮为平底,且觯的等级高于卮,目前考古出土的玉卮应为玉觯。通过数据分析,我们发现樽与觯的区分要点是容器的径高比差异,樽口大腹浅,便于盛取液体,而觯口小腹深,便于饮用液体。
