基于系统动力学的银行卡刷卡消费价格策略研究

银行卡刷卡消费系统是一个由网络运营商、发卡行、收单行、商户和消费者五个主体及相互作用组成的网络系统。为了使刷卡消费系统的定价策略能够有益于系统的长期发展,解决对刷卡消费价格的分析仅限于静态方面研究的局限,运用VENSIM软件,建立银行卡刷卡消费定价策略的系统动力学模型,并对模型的运行和模拟结果进行了动态分析,实证分析了银行卡刷卡消费各主体不同价格策略对刷卡消费主要指标的影响。     

Attaining Status at the Expense of Likeability: Pilfering Power Through Conversational Interruption

Do status expectations affect how we interpret interruption in conversation? Two experiments examined how interrupters and their targets are perceived in same- and mixed-gender dyads. In Experiment 1, participants listened to a brief audiotaped conversation in which one person interrupted the other five times. In Experiment 2, four confederates (two men and two women) systematically interrupted naïve participants while discussing an article. In general, interrupters gained in status and targets of interruption lost status. In addition, participants who were interrupted rated themselves as less influential than those who were not interrupted. As expected, interrupters, especially female interrupters, were liked less than those who did not interrupt. Theoretical implications are discussed.     

一种实用的混沌保密编码方法

基于实用符号动力学的基础理论,提出了一种实用的混沌保密编码方法,该方法借助于单峰的logistic映射处于混沌吸引子状态时产生的符号序列作为密钥,对信源编码信号进行加密。使用数字可编程芯片TMS320VC5402实现了实时保密编码,并对混沌符号密钥的相似性作了分析。研究表明,该方法在实际应用中具有推广价值。     

完全的广义变分原理在分析动力学中的应用

本文提出并证明了分析动力学中的各级不完全的广义变分原理和一个完全的广义变分原理.文中首次把开关函数应用于变分原理,使论述简洁明了.在这些变分原理中,动力学方程、初始位置条件、终了位置条件和几何约束条件,全部或者部分地不是事先必须满足的,即它们已成为变分原理的自然条件,因此给试函数的设计和分析力学的变分计算提供了一种新的有效的方法.

Stability and Complexity of Inter-Firm Co-operation:: The case of Multi-Point Alliances

The authors examine alliances involving inter-firm co-operation which they term ‘multi-point alliances’. These are first defined and considered in varying degrees of complexity. A typology of multi-point alliances is produced, and interviews conducted with French and Spanish corporations followed by a two-stage questionnaire survey of France's largest corporations. The dynamics of multi-point co-operation were then examined. The results include support for the authors' research hypothesis that both business complexity (scope) and organizational complexity (structure) impact the evolution of co-operation: the higher the complexity, the more likely the co-operative arrangement will diverge from its initial objective.

Governance dynamics in inter-organizational networks: A meta-ethnographic study

Governance has been a pervasive theme in the discussions of strategy and management in the context of inter-organizational networks. To date, network researchers call for a dynamic theory of governance to deal with increased uncertainty in the network environment. In response to this call, this study aims to generate a better understanding of how and why governance in inter-organizational networks can change over time and what implications these governance dynamics have for the network and its members. A meta-ethnographic analysis of 15 longitudinal case studies reveals that network actors can combine relational and formal governance in different ways over time, thereby constituting three governance patterns: the relational celebration pattern, the competitive protection pattern, and the forced facilitation pattern. The relational celebration and competitive protection patterns can generate favorable outcomes for the network and its members if disagreement about the formal governance terms is eliminated by revising these terms and/or repeating the pattern with a subset of the network members. In the case of the forced facilitation pattern, favorable network outcomes emerge if different types of relational governance are balanced. By detailing how and why governance patterns emerge and can generate favorable outcomes for the network and its members, the present research creates a better understanding of governance dynamics for researchers, business practitioners, and policymakers.
