Social networks and opportunity recognition: A cultural comparison between Taiwan and the United States

This paper investigates the moderating effect of national cultural contexts on the relationship between social networks and opportunity recognition. Data obtained from Taiwan and the United States support the proposition that cultural contexts, specifically the individualism‐collectivism dimension, moderate the relationship between tie strength, structural holes, and opportunity recognition. Results indicate that in the United States, tie strength is negatively associated with opportunity identification and structural holes are positively associated with opportunity identification; whereas in Taiwan we find the opposite. The results also show that the interaction effect between bridging ties and tie strength on opportunity recognition varies depending on the cultural context.

Political Tie Heterogeneity and the Impact of Adverse Shocks on Firm Value

Past research has recognized the contingent value of corporate political ties but largely neglects their heterogeneity. Drawing on the political embeddedness perspective and literature on emerging economy political institutions, we develop hypotheses regarding how political networks comprising managerial and government ownership ties may have different valuation effects in the face of adverse political shocks. Examining stock market responses to an unanticipated, high‐profile political event in China, we find a negative valuation effect of managerial ties to municipal government, but an insignificant effect of government ownership ties. Further, companies combining managerial and ownership ties experienced less post‐shock reduction in market value than those holding only managerial political ties. These findings shed light on the values of different configurations of corporate political ties and inform firms of potential ways to manage ubiquitous political hazards in emerging economies.     

Knowledge Cooperation Diversification Strategy for Tourism Scholar Creativity: The Moderating Role of Tie Strength

This study proposes a novel theoretical framework for studying different perspectives on knowledge diversity and creativity, including both the benefits and costs of knowledge searching across different fields of expertise. Data on 1,340 tourism scholars over 31 years show a consistent horizontal S-shaped relationship between knowledge diversity and creativity. Furthermore, tourism scholars who invested more effort in maintaining good relationships with partners, such as through network ties, achieved greater profitability gains from cooperation diversification strategies and scholar creativity. Our framework and findings highlight the complexity and temporal dynamics among tourism cooperation networks.     

The Service Industries Journal: Its Ethos and Emphases

This study investigates the dynamics of customer affection and customer trust on customer loyalty intention after cases of service failure and recovery. The results demonstrate that after customers experience service failure and recovery, customer affection has a greater influence on customer trust but less in loyalty intention, whereas customer trust becomes more influential in loyalty intention in comparison to the time prior to a service failure. The findings suggest that the rebuilding of loyalty after a service failure and recovery relies primarily on the recovery of trust and that the key determinant of trust recovery is customer affection. Theoretical and managerial implications are also discussed.     

网络关系强度与组织学习：环境动态性的调节作用

本文以环境动态性为调节变量,构建了网络关系强度对组织学习影响的概念模型。通过多元线性回归分析,对网络关系强度如何影响组织学习的问题进行了实证研究,得出以下结论：弱关系有利于探索式学习,环境动态性对网络关系强度与探索式学习的关系调节效应不显著;强关系有利于利用式学习,环境动态性对网络关系强度与利用式学习的关系具有调节效应,在稳定的环境下,强关系对企业利用式学习具有更大的影响作用。本文的结论对企业组织学习理论和实践具有一定的指导意义。
