信誉主体及其产权基础

经济学视域中的信誉是坚持诚实交易、信守合约所获得的声誉。经济学所分析的信誉主体是指那些诚实交易、信守合约的个人和组织。从现实社会看,经济学的信誉主体仅仅是市场主体之一部分。由市场主体必须是产权主体的命题,可以逻辑地推导出信誉主体必须是产权主体的命题。产权是信誉主体确立的基础,原因在于第一,置信的承诺显然与主体履约能力的大小密切相关;第二,交易性互动必须建立在交易各方的产权基础之上;第三,有恒产者追求的已不再是短期利益的最大化,而是长期利益的最大化,如果失信将面临巨大的风险。     

计算中国男性人体环节体积的二元回归方程的研究

采用CT—图像分析法,在尸体研究的基础上,对50例中国男性样本(18～23岁)进行了全身CT横断层扫描、影像分析和测算,获得了样本各环节的长度和体积等惯性数据。进而确定了中国男性青年人体体积的分布,并据此建立了以身高、体重为自变量的直接计算中国青年人体各环节体积的二元回归方程。     

Queers,Bodies and Postmodern Sexualities: A Note on Revisiting the “Sexual” in Symbolic Interactionism

This article reflects on the linkage between developments in symbolic interactionist theory over the past thirty years and the sociological study of the social construction of sexualities. After some personal reflections on the development of the theory, four main themes are highlighted: the links to postmodernism and queer theory; the paths to new research styles; some internal problems with the theory; and the need to reinstall the importance of the body. The article concludes that symbolic interactionism remains a major approach to the study of sexuality.     

Predicting body fat using weight–height indices

While body fat is the most accurate measure of obesity, its measurement requires special equipment that can be costly and time consuming to operate. Attention has thus typically focused on the easier to calculate body mass index (BMI). However, the ability of BMI to accurately identify obesity has been increasingly questioned. This paper focuses attention on whether more general body mass indices are appropriate measures of body fat. Using a data set of body fat, height, and weight measurements, general models are estimated which nest a wide variety of weight–height indices as special cases. In the absence of a race and gender categorisation, the conventional BMI was found to be the appropriate index with which to predict body fat. When such a categorisation was made, however, the BMI was never selected as the appropriate index. In general, predicted female body fat was some 10 kg higher than that of a male of identical build and predicted % body fat was over 11 percentage points higher, but age effects were smaller for females. Considerable racial differences in predicted body fat were found for males, but such differences were less marked for females. The implications of this finding for interpreting recent research on the effect of obesity on health, society, and economic factors are considered.

基于模仿者动力学模型的外在制度实施过程研究

外在制度在大群体组织中的实施是个复杂的过程.这一过程中,组织成员的理性程度较低而且行为相似,较适合用对称的模仿者动力学模型来分析.外在制度虽具有一定的自实施功能,但实施过程中实施者的主动性和创造性也很重要.借助于模型和案例分析,实施者可在现实中通过适当操作来控制实施环境,增强外在制度的实施效果.

身体的澄明之途——对西方哲学中的“身体性”问题的思考

从身体的维度出发,揭示了西方哲学对“身体性”问题两种截然不同的解答：其一,传统西方哲学将肉体和心灵的关系置于一种对立二元论的基本构架中,使肉体在意识哲学中一直处于一种隐匿和遮蔽的状态。其二,后现代哲学家用“肉体”来反抗意识哲学的独断性。展开了所谓的“哲学肉身化”运动,又将肉体以及与肉体相关的一切推上了至高无上的地位。以上这两种哲学在“身体性”问题上仍然是一种“非此即彼”的、“独白式”的主体性哲学,而要真正解决“身体性”问题,只有坚持的一种“身体间性”维度的现象学精神,才可能达到“身心合一”的完美之境。     

The Evolution of Knowledge and the Dynamics of an Industry Network

The paper moves a step forward in the direction of establishing a connection between the structure and evolution of knowledge bases and the structure and evolution of organizational forms in innovative activities in a science-intensive industry. The paper has an explicit focus on the dynamics of the network of collaborative agreements in R&D in the pharma/biotech industry after the “molecular biology revolution”. Using a comprehensive dataset, built by the authors integrating several sources in the industry, the dynamics of the network over time is extensively analyzed. With regards to network structure, it is found that, while the size of the network increases over time due to net flows of entry, its topological properties remain relatively unchanged. The evolution of the network has occurred without relevant deformations in the core-periphery profile. With regards to age-dependent propensity to collaborate, the paper finds that the extent of inter-generational collaboration is much more significant than intra-generational collaboration. In addition, the propensity of firms of a given generation to enter into collaboration with firms of a different generation increases with the distance between the two, while the total number of intra-generational collaborations decreases over time and, moreover, tends to decrease for most recent generations. In the paper a unitary and coherent explanation of the evidence is developed, coming to reveal the existence of a striking isomorphism between structural properties of the dynamics of knowledge and of the evolution of network structure. This revised version was published online in July 2006 with corrections to the Cover Date.     

从身心到艺术：魏晋名士艺术境界的形成路径

魏晋名士艺术境界的形成路径清晰而富于哲理,他们通过心身外在表现的审美追求以获得艺术对象审美外观的人格化,通过“远”之本体追问与“远”之身体探寻来实现人生和艺术的玄远境界,使得“心”臻至“无”之境与“美”臻至“无我”之境在人生与艺术层面完美融通。如此,魏晋名士与肉身以及欲望存在的自我渐行渐远,而生命精神却始终作为不可或缺的逻辑线索,延续于人生、艺术之中,成为艺术精神和人格蕴含的内在逻辑线索。
