ABSTRACT
Crisis information dissemination plays a key role in the development of emergency responses to epidemic-level public health events. Therefore, clarifying the causes of crisis information dissemination and making accurate predictions to effectively control such situations have attracted extensive attention. Based on media richness theory and persuasion theory, this study constructs an index system of crisis information dissemination impact factors from two aspects: the crisis information publisher and the published crisis information content. A multi-layer perceptron is used to analyze the weight of the index system, and the prediction is transformed into a pattern classification problem to test crisis information dissemination. In this study, COVID-19 is considered a representative event. An experiment is conducted to predict the crisis information dissemination of COVID-19 in two megacities. Data related to COVID-19 from these two megacities are acquired from the well-known Chinese social media platform Weibo. The experimental results show that not only the identity but also the social influence of the information publisher has a significant impact on crisis information dissemination in epidemic-level public health events. Furthermore, the proposed model achieves more than 95% test accuracy, precision rate, recall value and f1-score in the prediction task. The study provides decision-making support for government departments and a guide for correctly disseminating crisis information and public opinion during future epidemic-level public health events.
ABSTRACT
During the COVID-19 pandemic, the use of social media platforms for working online has become a global phenomenon. For female employees, social media usage has made it easier to balance work and family, but the pressures have also multiplied. Especially in China, the COVID-19 prevention policies led to dramatic changes in working patterns, which significantly affected the emotions, cognitions, and behaviors of female employees. Based on the job demands resource theory, this study explores the double-edged effect of social media usage on job crafting for female employees. Survey data were collected from 563 female employees in Chinese enterprises. Hierarchical regression analysis and the bootstrap method by SPSS and AMOS software were used to test the hypotheses. The results show that work-related social media usage has a negative effect on job crafting, while social-related social media usage has a positive effect. Moreover, job autonomy and workplace friendship mediate the relationship between them. This study extends the research on the double-edge effect of female employees' social media usage and enriches the antecedents and influencing mechanisms of job crafting. It also provides theoretical and practical guidance for managers on how to promote the sustainability of human capital during the COVID-19 pandemic.
ABSTRACT
Remote work has become a new way of working due to the influence of the COVID-19 pandemic, which inevitably aggravates team conflicts caused by cognitive differences given the lack of face-to-face communication. With a team climate perspective, this paper investigates the impact of the team leader's conflict management style on team innovation performance in remote R&D teams in China based on social cognition theory and two-dimension theory. A theoretical model is constructed which describes the mediating effect of team psychological safety and the moderating impact of team trust. Paired data from 118 remote R&D teams in China including 118 leaders and 446 members were collected. The results show that team leader's cooperative conflict management style is conducive to enhancing team psychological safety and further effectively improves team innovation performance. Therefore, team psychological safety has a mediating effect between team leader's cooperative conflict management style and team innovation performance. In addition, team trust has a negative moderating effect between team leader's cooperative conflict management style and team psychological safety. Besides, this study obtains some valuable culture-related insights and provides more views for conflict management research in the cross-cultural context since the samples in this study are from China, a society with high collectivism, which is different from the western cultural context from which many conflict management theories develop.
