西江流域两广开发利用的博弈策略及其仿真

针对西江流域开发过程中出现的水源林面积减少、水土流失严重、移民安置、水体污染严重等由经济发展带来的负面生态文明问题,采用演化博弈方法探究西江流域两大治理主体广西政府与广东政府的策略与可能产生的改变与均衡。结果表明,传统情况下两广政府博弈系统将朝着(过度开发,不合理加速)的帕累托最劣稳定状态演化,不利于西江流域生态的绿色可持续发展；引入问责机制对广西政府“过度开发”和广东政府“不合理加速”进行惩罚,博弈系统存在9种演化情景,当且仅当满足特定条件时,系统会收敛到(适度开发,合理加速)的帕累托最优状态；数值仿真模拟下根据惩罚值高低设计9种不同情景,分析惩罚值对博弈结果的影响,发现在中央政府及上级相关部门给予两广政府的问责惩罚都较高时,博弈系统朝着帕累托最优状态演化；为促进西江流域生态经济与治理的均衡发展,在问责机制设计上,要给予两广政府满足相应条件的较高惩罚值。

The multibody system transfer matrix method (MSTMM), a novel dynamics approach developed during the past three decades, has several advantages compared to conventional dynamics methods. Some of these advantages include avoiding global dynamics equations with a system inertia matrix, utilizing low-order matrices independent of system degree of freedom, high computational speed, and simplicity of computer implementation. MSTMM has been widely used in computer modeling, simulations, and performance evaluation of approximately 150 different complex mechanical systems. In this paper, the following aspects regarding MSTMM are reviewed: basic theory, algorithms, simulation and design software, and applications. Future research directions and generalization to more applications in various fields of science, technology, and engineering are discussed.     

Order effect of multi-touchpoints on Generation Z consumers

Abundant user-generated content has increasingly driven consumers to form or modify their purchasing decisions based on interactions with other consumers, although the extant research overlooks the customer-to-customer (C2C) interaction touchpoints. Based on the customer journey characteristics of cross-channel and multi-frequency interactions, this study explores the impact of interaction valence and interaction channel sequence on Generation Z consumers' purchase attitudes from the perspective of attitude modification process. Using a scenario-based experimental design in a restaurant setting, we sample 616 Generation Z students. Findings suggest that C2C interactions that have the same valence at each touchpoint strengthen Generation Z consumers' initial purchase attitude, whereas inconsistent valences modify purchase attitudes. Our results reveal that a negative-to-positive ordering is more conducive to the formation of a positive purchase attitude than a positive-to-negative ordering. Moreover, the cross-channel sequence of a customer journey moderates the inconsistent valence order such that the positive-to-negative order improves purchase attitude more than the negative-to-positive order. This study explains theoretically the difference of ambivalent experiences on Generation Z consumer attitudes. We provide practical suggestions for multi-channel restaurant enterprises to successfully employ customer journey touchpoint management.
