Opinion dynamics and wisdom under conformity

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors’ expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an agent׳s social influence on the long-run group opinion is increasing in network centrality and decreasing in conformity. Concerning efficiency of information aggregation or “wisdom” of the society, it turns out that misrepresentation of opinions need not undermine wisdom, but may even enhance it. Given the network, we provide the optimal distribution of conformity levels in the society and show which agents should be more conforming in order to increase wisdom.     

Network games with incomplete information

We consider a network game with strategic complementarities where the individual reward or the strength of interactions is only partially known by the agents. Players receive different correlated signals and they make inferences about other players’ information. We demonstrate that there exists a unique Bayesian-Nash equilibrium. We characterize the equilibrium by disentangling the information effects from the network effects and show that the equilibrium effort of each agent is a weighted combinations of different Katz–Bonacich centralities.     

协作型企业供应链管理

供应链管理作为一种新型的企业关系管理模式在现代市场竞争中为企业生存与发展提供了一种工具。本文针对协作型企业供应链管理进行了研究。协作型企业供应链由于其业务联系上的紧密性与其他供应链有所不同，在生产计划制定上强调生产计划的一致性与协调性，核心企业与供应企业在生产计划制定方面的信息共享；在销售管理上强调企业与销售商集成式管理。     

论供应链管理环境下的物流管理

供应链管理是随着全球制造、全球化经营趋势的迅猛发展孕育而生的一种新的物流管理模式和思想，是物流管理的一场革命。与此同时，物流管理在此大环境下，又呈现出许多新的特点和规律。本文对此问题从供应链管理的科学内涵、供应链管理与物流管理的内在关系以及供应链管理下的物流管理三个方面进行了论述。     

供应链管理中的协调机制设计

本文首先指出协调问题是供应链管理中的核心问题,阐述了协调机制的理论背景,基于博弈论和机制设计理论给出了协调机制的形式化描述,在此基础上提出协调机制设计的思路和方法,并指出委托代理理论是协调机制设计中的一个重要理论工具。     

A replication and extension of quality management into the supply chain

As competition moves beyond a single firm into the supply chain, researchers are beginning to explore quality management (QM) in a supply chain context. The literature suggests that supply chain management (SCM) consists of internal practices, which are contained within a firm, and external practices, which cross organizational boundaries integrating a firm with its customers and suppliers. Supplier quality management and customer focus are two QM practices that are also clearly in the domain of SCM. In this study we investigate how these two supply chain management-related quality practices lead to improved performance and examine the practices that precede and mediate those relationships. In doing so, we replicate and extend the relationships among the QM practices and their effects on firm performance suggested in Kaynak [Kaynak, H., 2003. The relationship between total quality management practices and their effects on firm performance. Journal of Operations Management 21, 405–435] using survey data gathered from firms operating in the U.S. The inclusion of customer focus and supplier quality management in the QM model supports the importance of internal and external integration for quality performance. Implications of the results for researchers and practitioners are discussed, and further research implications are suggested.     

Managing five paradoxes of knowledge exchange in networked organizations: new priorities for HRM?

The life‐blood of most organizations is knowledge. Too often, the very mechanisms set up to facilitate knowledge flow militate against it. This is because they are instituted in a top‐down way, they are cumbersome to manage and the bridges of trust fail to get built. In their thirst for innovation, the tendency is for firms to set up elaborate transmission channels and governance systems. As a result, staff are drowned in a deluge of mundane intranet messages and bewildered by matrix structures, while off‐the‐wall ideas and mould‐breaking insights are routinely missed. Added to this is the challenge of operating across professional, cultural, regional and linguistic boundaries, where ways of sharing knowledge differ markedly, even within the same project team. Drawing upon extensive research with scientists in the ATLAS collaboration (a high‐energy particle physics experiment comprising 3,500 scientists from 38 countries), we explore five paradoxes associated with knowledge exchange in global networks. Each paradox leads to a proposition which takes the theory and practice of knowledge management in a fresh direction. We conclude by outlining a number of HRM priorities for international knowledge‐intensive organizations.     

Sustainable humanitarian supply chain management – exploring new theory

Disaster response operations aim at helping as many victims as possible in the shortest time, with limited consideration of the socio-economic context. During the disaster rehabilitation phase, the perspective needs to broaden and comprehensively take into account the local environment. We propose a framework of sustainable humanitarian supply chain management (SCM) that facilitates such comprehensive performance. We conceptualise the framework by combining literature from the fields of sustainable and humanitarian SCM. We test the framework through an analytic induction process by means of multiple case studies of four relief organisations. Our framework suggests that supply chain design needs to be aligned not only to relief organisations’ enablers, but also to the population's long-term requirements as well as any socio-economic and governmental contingency factors. A good fit between these dimensions leads to sustainable performance. The framework provides an instrument for relief organisations to achieve sustainable performance in the disaster rehabilitation phase.     

Success factors for continuous supply chain process improvement: evidence from Japanese manufacturers

This study explores how firms can realise ‘continuous’ supply chain process improvement. Specifically, this study proposes the success factors of routinised activities (also called ‘repeated activities’) in the supply chain process improvement. Eight Japanese manufacturers are selected for the case studies. These firms are selected based on their supply chain process operation capabilities. From the case studies, we find that the planning of supply chain process improvement depends on the existing stage of the firm’s Supply Chain Management reform. In addition, even firms with high scores for supply chain process operation capabilities do not have supply chain performance systems. Furthermore, quite surprisingly, many Japanese manufacturers tend to improve their supply chain processes in the absence of such systems.     

Does obligational contracting lead to better performance? A comparison of global carmakers’ supply chain management approaches in Australia

Supply chain management (SCM) has been recognised as key to automobile manufacturers’ (‘buyers’) competitive advantage. However, the performance implication of two different approaches towards SCM, obligational contracting (OCR) vs. arm’s length contracting (ACR), remains inconclusive in the current literature. By focusing on examining how multiple global automobile manufacturers’ SCM practices result in different performance outcomes in the one-country setting of Australia, we are able to ascertain the direct impact of SCM approaches on buyers’ performance. We also provide detailed analysis on the specific influence of each distinguishing feature of the OCR/ACR approaches on different aspects of performance. Through a more nuanced investigation of the links between SCM approaches and automobile manufacturers’ performance at the firm level, this research contributes to a better understanding of the topic with managerially applicable insights.
