This paper aims to explore the influence of social support and the repatriation intention of expatriates in international constructions in the postpandemic era of COVID-19. Furthermore, test the mediation effect of team climate and individual resilience in this relationship. A survey of 347 expatriates in international construction projects was conducted. A cross-level chain mediation model was employed to test the moderating effect of social support and repatriation intention. Then, statistical analysis with a bootstrap sample was used to test the mediation effect of the model. The empirical results support that team climate, individual resilience and the chain mediating effect of team climate to individual resilience is significant among the influences of social support on repatriation intention. Social support can enhance the team climate of construction expatriates, promoting their resilience to reduce the repatriation intention further. This study provides guidelines for international construction enterprises and managers to decide when and which expatriates should return home and formulate a series of policies to support expatriates and maintain a good team climate. This study contributes to expatriate management literature by establishing the relationship between social support and repatriation intention. It provides a better understanding of how team-level factors impact individual thought. It takes team climate as one of the protective factors affecting individual psychological resilience. Also it takes social support as the antecedents of team atmosphere in case of emergencies.

Purpose: This study aims to investigate the relationship between individual-level psychological resources and team resilience in the context of expatriate project management teams. It seeks to understand how personal psychological resources contribute to team resilience and explore the dynamic evolution mechanism of team resilience. The goal is to enhance team resilience among expatriates in a BANI (Brittle, Anxious, Nonlinear, and Incomprehensible) world, where organizations face volatile and uncertain conditions. Design/methodology/approach: An online survey was applied for data collection, and 315 valid samples from Chinese expatriates in international construction projects were utilized for data analysis. A structural equation model (SEM) examines the relationships between personal psychological resources and team resilience. The study identifies five psychological factors influencing team resilience: Employee Resilience, Cross-cultural Adjustment, Self-efficacy, Social Support, and Team Climate. The hypothesized relationships are validated through the SEM analysis. Additionally, a fuzzy cognitive map (FCM) is constructed to explore the dynamic mechanism of team resilience formation based on the results of the SEM. Findings: The SEM analysis confirms that employee resilience, cross-cultural adjustment, and team climate positively impact team resilience. Social support and self-efficacy also have positive effects on team climate. Moreover, team climate is found to fully mediate the relationship between self-efficacy and team resilience, as well as between social support and team resilience. The FCM model provides further insights into the dynamic evolution of team resilience, highlighting the varying impact effects of antecedents during the team resilience development process and the effectiveness of different combinations of intervention strategies. Originality/value: This study contributes to understanding team resilience by identifying the psychological factors influencing team resilience in expatriate project management teams. The findings emphasize the importance of social support and team climate in promoting team resilience. Interventions targeting team climate are found to facilitate the rapid development of team resilience. In contrast, interventions for social support are necessary for sustainable, long-term high levels of team resilience. Based on the dynamic simulation results, strategies for cultivating team resilience through external intervention and internal adjustment are proposed, focusing on social support and team climate. Implementing these strategies can enhance project management team resilience and improve the core competitiveness of contractors in the BANI era.

The current method’s e‐commerce credit risk assessment is prone to poor data balance and low evaluation accuracy. An RB‐XGBoost algorithm‐based e‐commerce credit risk assessment model is proposed in this study. The adaptive random balance (RB) method is used to sample and process the obtained data to improve the balance degree of the data. An assessment index system is constructed based on the processed data. Based on the risk evaluation index system and the XGBoost algorithm, this paper constructed an e‐commerce risk assessment model and assessed the e‐commerce credit risk using this model. The experimental results show that the proposed method has good data balance, a high kappa coefficient, and a large receiver operating characteristic (ROC) curve area, which can effectively improve e‐commerce credit risk assessment accuracy.

Coopetition is a revolutionary mindset that combines competition and cooperation. This paper aims to determine and to explore the critical factors affecting contractors’ coopetition relationship (CR) in international construction projects (ICPs). In order to improve CR between international contractors in ICPs, a comprehensive literature review was performed to identify the potential variables affecting the CR. A questionnaire survey of 151 professionals in both academia and industry, which included 53 variables, was conducted to explore the critical factors affecting international contractors’ CR in ICPs. Structural equation modeling (SEM) was employed to evaluate the multivariate interrelationships among those variables. As a result, nine underlying factors, including six internal factors and three external factors, were extracted and interpreted. The findings can help international contractors to understand more accurately how the coopetition relationship between contractors is affected and can provide a basis for follow‐up research on how to evaluate the coopetition status of contractors and the coopetition strategies adopted in ICPs.

Introduction: The rapid increase in international students in China underscores the imperative to understand their successful adaptation. This study investigates the roles of identity and psychological resilience in facilitating college adjustment among international students confronting culture shock in China.Methods: Drawing upon Social Identity Theory and Identity Consolidation Theory, we hypothesized that a strong sense of identity would positively influence psychological resilience, mediating the relationship between identity and college adjustment. A quantitative survey was conducted with 2,097 international students in various universities across China.Results: The findings indicate that identity significantly predicted higher levels of psychological resilience, and psychological resilience, in turn, was a strong predictor of better college adjustment. Furthermore, psychological resilience significantly mediates the relationship between identity and college adjustment, suggesting that a well-defined identity contributes to resilience, equipping students to navigate the challenges of culture shock and adapt successfully to university life.Discussion: These results provide valuable insights for developing targeted support programs and interventions to enhance international students’ well-being and successful integration in China.
