基于精确模态参数的桥梁损伤识别

利用系统动力参数进行土木工程结构的损伤识别已经成为了一个非常重要的研究领域,因此需要一种利用损伤前后动力参数的变化进行损伤评估和定位的有效方法,系统的动力参数必须尽可能的精确。本文通过有限元方法对一简支梁桥进行动力分析,利用壳单元对桥面进行离散化,通过降低刚度来模拟损伤,进行损伤前后动力参数计算,可以发现损伤前后固有频率的变化。利用位移模态提取的曲率模态进行损伤定位要比位移模态更敏感。

Rethinking Money as an Institution of Capitalism and the Theory of Monetary Circulation: What Can Modern Heterodox Economists/Institutionalists Learn from Karl Polanyi?

Modern heterodox theories of money reject the neoclassical conception of money as primarily a medium to facilitate exchange. These heterodox theories of money all have as common starting point an analysis of credit-debt relations in which production is a central feature, with these economies organized along capitalistic design. The Keynesian-Marxian framework describing the process of monetary circulation, traditionally referred to as the theory of the monetary circuit (TMC), perhaps best represents this comprehensive vision. This broad TMC analytical framework is compatible with institutionalist theories of money that also point to the importance of credit-debt relations. The question, however, is whether this more unified heterodox theory of money, which describes sequentially monetary relations under capitalism, can be used to understand pre-capitalistic monetary institutions. By conceptualizing money as a means of payment rather than medium of exchange, Karl Polanyi’s analysis offers social scientists crucial insights to understanding monetary relations in all types of societies in which credit-debt relations have emerged historically.     

关于“苏州评弹口述史（百年）”的构想

评弹口述史不仅能够呈现一部多元、全息、个人化的评弹史，而且还为江南文化社会研究提供重要视角和资料。评弹百年口述史构建以艺人史为中心，旁及艺术发展史、书目传承史、流派演变史、书场史、社团史等部门或专题，以从多侧面呈现百年来评弹经历的风云变幻，以及与江南社会之间的因应、互动关系。     

从走出家庭看西丽的成长

艾丽斯.沃克的《紫色》是一部著名的反映黑人女性成长问题的成长小说,主人翁西丽的走出家庭独立谋生是小说的重要情节。西丽没有重蹈娜拉可能走的两条路,而是在物质上和精神上彻底独立起来,重新找回了自我,实现了人生的价值,为自己赢得了平等与尊重,终于完成了成长。西丽这一形象在当下社会对广大女性依然具有启迪作用和教育意义。     

On the efficiency of the negligence rule

The three versions of the negligence rule discussed in the literature differ regarding whether a negligent injurer is liable for the entire loss or only for the incremental loss; or regarding whether negligence is defined as failure to take at least due care or failure to take a cost‐justified precaution. It is shown in the paper that the incremental version with untaken precaution notion of negligence is not efficient; not even for the unilateral case. The paper also establishes, for the bilateral case, the efficiency of the incremental version with the shortfall‐from‐due‐care way of defining negligence.     

紫铜脉冲整形器的设计研究

利用ANSYS/LS-DYNA程序,采用Lagrange方法,对紫铜脉冲整形器的设计进行研究,结果表明:只要合理的控制脉冲整形器直径,撞击杆的撞击速率,就可以使反射脉冲平台处应变等于入射脉冲上升段的第一拐点处应变,此时混凝土就会以近恒应变率发生形变;对于同一尺寸的混凝土试件,混凝土试件能够达到近恒应变率值与紫铜脉冲整形器的直径之间呈线性增长关系。     

论吉利斯的长趋势性向解释

吉利斯的长趋势性向解释从批判频率解释的操作主义入手，以自然科学中关于概念更新的非操作主义理论为基础。为了使概率恰好地与频率相联系，吉利斯提出了概率陈述的可证伪规则，并运用这个规则推导出概率的统计频率稳定性定律和排斥赌博规律定律。     

Schooling in a Corporate Society

This article defines a measure of the quality of life in the regional capitals of Poland and compares the results. This taxonomic measure is based on a set of diagnostic traits, including housing conditions, state of the natural environment, labor market, personal safety, and range of cultural services available. For this purpose, a set of variables from 2011 was observed for each regional capital. This research is important in defining the difference between our target cities from the standpoint of social development. It also allows us to classify the cities into groups based on the quality of life of their inhabitants.
