分享经济: 研究评述与未来展望

目的/意义 互联网的迅速发展使分享经济成为一种新型商业模式,分享经济增长的潜力在于参与者的增长。拥有物质资源的消费者作为提供者参与分享经济,对经营分享经济的企业发展,提高资源利用率、减少浪费及环境可持续发展等有重要意义。 设计/方法 基于社会交换理论,构建了消费者物质主义对提供资源参与分享经济的关系假设模型,并通过问卷收集数据,运用结构方程对模型及假设进行分析与检验。 结论/发现 （1）经济价值、社会价值及情感价值在消费者物质主义与参与分享经济的关系具有中介作用。（2）不同的物质主义对参与分享经济意愿的作用机制存在差异：工具性物质主义通过经济价值、社会价值及情感价值的完全中介作用,对参与分享意愿产生显著的正向影响;而终极性物质主义对分享意愿有显著的负向直接效应,但通过经济、社会及情感价值的遮掩效应,对参与分享经济意愿产生正向的增强作用。     

Semantic Analysis of the Theoretical Foundations of Biology

生物学理论作为科学哲学研究中的一个另类一直受到关注。它与传统科学模式间的差异是造成这种现象的原因之一。解读这种差异的根源,需要对生物学的理论基础以及理论结构给予充分的关注。生物学特有理论结构所表现出的多元语境与语义结构的复杂性,决定了对生物学理论基础的研究应当重视语义分析的方法,尤其是对理论本身进行语义分解并研究其中的语义关联问题,从而解读生物学模式作为一种不同于理化科学的特殊科学解释观的合理性。     

对创新高校思想政治理论课实践环节的思考

思想政治理论课实践教学环节是理论课教学体系的重要部分,是提升教学效果的有效途径之一。目前,实践教学存在着思想认识上有偏差、缺乏规范有效的组织管理、缺少资金和基地保障、缺乏科学的考核和评价体系等诸多问题,需要通过转变观念、建立和完善组织管理机制、设立专项经费和实践基地、建立健全实践教学评价体系等途径,使理论课实践教学更具有可操作性和实效性。     

论辞格理论与辞格发展之间的互动

古代修辞理论与辞格发展之间存在着复杂的互动关系。本文通过个案分析,证实了三点:其一,辞格的发展、演变本质上依赖于语言、文体本身提供的可能性,辞格理论的影响只是在发展方向上的诱导,并且这种诱导并不是总能成功;其二,这种诱导以理论被辞格使用者认同为前提,而特定文化背景或文学思潮可增强这种认同感,从而强化诱导;其三,当辞格使用者面对关于这一辞格的不同的甚至对立的理论主张时,他们会作出折中或取舍;而理论创造者面对辞格的发展变化,也有可能作出新的概括或补充。     

Some theory and practical uses of trimmed L-moments

Trimmed L-moments, defined by Elamir and Seheult [2003. Trimmed L-moments. Comput. Statist. Data Anal. 43, 299–314], summarize the shape of probability distributions or data samples in a way that remains viable for heavy-tailed distributions, even those for which the mean may not exist. We derive some further theoretical results concerning trimmed L-moments: a relation with the expansion of the quantile function as a weighted sum of Jacobi polynomials; the bounds that must be satisfied by trimmed L-moments; recurrences between trimmed L-moments with different degrees of trimming; and the asymptotic distributions of sample estimators of trimmed L-moments. We also give examples of how trimmed L-moments can be used, analogously to L-moments, in the analysis of heavy-tailed data. Examples include identification of distributions using a trimmed L-moment ratio diagram, shape parameter estimation for the generalized Pareto distribution, and fitting generalized Pareto distributions to a heavy-tailed data sample of computer network traffic.     

“联系说”视角下商标俗称抢注案的法律思考

商标权的客体为相关公众所认知的商标与商标所标识的商品或服务之间的联系,以此为基础可以认定商标俗称的抢注构成对商标权的侵犯,同时,商标俗称可以被认定为近似商标的一种形式,从而适用《商标法》第52条的规定。此外,在商标俗称的问题上,不能适用法律对驰名商标的特殊保护。     

Path(ological) Dependency? Core Competencies from an Organizational Perspective

The development of the 'resource-based theory of the firm' has helped to reorient the field of strategic management towards a focus on the organizational processes and structures which produce 'core competencies'. By challenging previous assumptions of market determinism this approach seems to open up the prospect of a greater dialogue with the theories and concerns of organization studies. This paper aims to determine the scope of such a dialogue by developing an appreciation and critique of the core competencies framework from an organizational perspective. In this context, the key feature of resource-based theories is seen to be their focus on organizational knowledge rather than decision-making processes as the engine of competitive performance. This focus has a powerful resonance with studies of knowledge in organizations, particularly those forms of knowledge which are linked to product and process design.
However, despite the important shift towards a knowledge-based view of competition, the core competencies approach fails to follow the logic of its own argument as far as the organizational appropriation of knowledge is concerned. In their pursuit of an ontological model of competitive performance –defining the essential causes of firm competitiveness – resource-based approaches neglect the socially embedded qualities of organizational knowledge. As a result, the social construction of knowledge, encompassing the dilemmas posed by the employment relationship and the pitfalls of institutionalization, is neglected. Instead, a smoothly linear model is developed linking skills, competence and competitiveness. This mechanistic view is further reinforced by reliance on a command and control model of the management process. Organizational knowledge is not a biddable resource at the disposal of top management.

静电电子回旋脉塞的单粒子理论

本文用单粒子理论研究了静电电子回旋脉塞。通过对静电电子回旋脉塞中的电子运动的分析,导出了电子与波互作用的非线性摆方程。文中用二阶扰动方法求解非线性摆方程,得到了TE_(mn)和TM_(mn)两种工作模式的静电电子回旋脉塞不稳定性线性增益公式,进一步证实了静电电子回旋脉塞不稳定性是存在的。
