Ronald Coase's Method of Building More Realistic Models of Choice

This paper argues that Ronald Coase's major contributions to economic theory are best understood in terms of the distinct method he used to build more realistic models of choice. We call his method the benchmark-comparison method. It consists of building models of choice and then using them as benchmarks in the further investigation of economic interaction, either by comparing the benchmark models with observed interaction or by building additional models of choice, which may themselves function as benchmarks. The paper first describes the method then demonstrates how Coase used it in his two most famous papers. We go on to show how an understanding of the method confirms Coase's own statements about the continuity of his thought. Finally, we assess Coase's critique of Milton Friedman's positivist methodology and discuss a recent paper on Coase's methodology.     

Fostering mutual gains: Explaining the influence of high‐performance work systems and leadership on psychological health and service performance

Despite the growing importance of sustainable management of human resources, human resource management and leadership research on mutuality in the employment relationship has proceeded in a parallel fashion. Drawing on self‐determination theory, this study proposes an integrative model of human growth by addressing two interrelated questions: (a) how and why experienced service‐oriented high‐performance work systems (HPWS) and unit service leadership relate to psychological health and service performance and (b) whether thriving at work and psychological health serially mediate the relationships between the two contextual antecedents and service performance. Our findings revealed that experienced service‐oriented HPWS and unit service leadership related to service performance but indirectly through thriving at work. However, experienced service‐oriented HPWS but not unit service leadership related to psychological health through thriving at work. Furthermore, thriving at work and psychological health serially mediated the relationship between experienced service‐oriented HPWS (but not unit service leadership) and service performance.

Direct broadcasting by satellite in the USA: Interim regulations and implications

Technological advances in satellite communications and changes in regulatory philosophy in the USA came together at the end of the 1970s to foster a new medium — direct broadcasting by satellite (DBS). DBS, similar to other new television distribution systems, holds the promise not only of serving the people who cannot be reached by conventional television systems, but also of offering diverse programming to existing television audiences. However, the potential problems raised by the FCC's interim DBS regulations might jeopardize the economic viability and the development of future DBS systems in the USA, and might affect the interests of DBS audiences.     

Guanxi: Personal connections in Chinese society

Guanxi is known to be an important feature of Chinese society, and while studies of the subject are voluminous, the present study attempts to explore two critical aspects that tend to be neglected. First, previous studies have mostly dealt with guanxi in business activities, but we analyze the meanings of guanxi in the context of ordinary people. More importantly, even though guanxi has routinely been attributed to Confucianism, it begs the more fundamental question of why Chinese society has developed Confucianism and why the latter has become the dominant ideology over the centuries. We provide a plausible account of this important question from both sociological and economic perspectives. Secondly, we illustrate the general implications of guanxi in Chinese society, in particular relating guanxi to the development of democracy and of the rule of law. Consequently, its significance in Chinese society is actually more important than what has been suggested in the literature. Finally, we present some preliminary empirical evidence, based on survey results, of the importance of guanxi in contemporary Chinese society.

一般位置上的双摄像头立体视觉测距

本文基于一般位置上的双普通摄像头通过立体视觉的方法进行测距研究。为了减少错误匹配点对的个数,先采用Harris角点检测法对双摄像头捕获的两幅图像进行角点检测,然后将检测出的角点作为候选特征点,结合SIFT立体匹配算法实现对应点的匹配,从而进一步进行测距,该方法提高了测距的精度。     

数字媒体并行开发中的柔性调度模型的研究

基于第二代VBE的城市应急物流联盟协作框架

针对我国城市突发事件应急物流活动特点以及应急物流协作中存在的主要问题,可建立一种基于第二代虚拟组织培养环境模式,由政府主管部门领导,吸纳各类社会机构参与,立足于长期合作的城市应急物流联盟协作框架。该框架主要包括应急物流联盟的组织模型、智能化信息平台模型、生命周期模型等三个组成部分。该框架不仅可以降低应急物流团队构建的资金与时间成本,支持应急物流团队的配置评估与动态调整,提高应急物流活动中指挥与协调的效率,而且可以充分利用当前空闲服务能力获取额外利益或实现自身社会价值,提高联盟参与机构之间在应急物流领域之外进行合作的可能性,优化参与机构自身组织结构、业务流程、资源分配与管理原则,提高成员机构信息管理与交换水平以及知识管理水平。从经济角度看,该框架的实施既有政府专项资金支持,又有应急物流社会参与机构投资;从技术角度看,支持应急物流联盟/团队信息平台的相关技术已经比较成熟了;从管理与组织角度看,绝大部分与管理相关的问题都在框架考虑之中,具备可行性。但是,由于该城市应急物流协作框架尚处于早期发展阶段,对某些结构和功能,还需要进一步研究和扩展,以更好地适应复杂、多变的真实救援环境。
