Analyzing the impact of psychological capital and work pressure on employee job engagement and safety behavior

The effects of psychological capital, work engagement and job autonomy on job performance in platform flexible employees

The performance of platform flexible employees is a core element that contributes to the rapid growth of the sharing economy platform. It is crucial to explore strategies to improve employees' performance with the growing competition among these platforms. Only a handful of research evidence has been found evaluating platform flexible employees' psychological capital and work engagement to improve their performance. In order to remedy the gap, we draw on self-determination theory to develop a moderated mediation model, which examines how psychological capital affects platform flexible employees' job performance. We employed hierarchical regression analysis to test the theoretical model and carried out two rounds of surveys, resulting in 474 valid paired questionnaires. The questionnaire assessed the psychological capital, work engagement, job performance, and job autonomy of flexible platform employees. The results indicate that work engagement plays a mediating role between psychological capital affects platform flexible employees' job performance. Moreover, job autonomy moderates the mediating effect. The findings not only contribute to the literature on employees' psychological capital and job performance, but also broaden the research scope of self-determination theory, and provide new ideas for improving the job performance of platform flexible employees.

How does workplace support promote postdoctoral career growth? A conservation of resources perspective

Background

Postdoctoral researchers are critical to scholarly advancements, and promoting postdoctoral career growth is an endogenous path to help postdocs break through the "encircled city of scientific research". However, further research is needed to fully explore the mechanisms that connect workplace support to postdoctoral career growth.

Methods

Drawing from the Conservation of Resources theory, this study proposes a chain mediation model that demonstrates how workplace support enhances career growth by connecting psychological capital with work-life balance. To understand the motivation and career growth of postdocs in China, we conducted two questionnaires in 2021 and 2023 with the support of relevant stations.

Results

Analyzing 367 questionnaires from Chinese postdocs, our research indicates that workplace support has a positive impact on career growth. Additionally, both psychological capital and work-life balance are key factors that contribute to career growth, serving as separate mediators and as part of a chain of mediators.

Discussion

This study validates the appropriateness of the Conservation of Resources theory in the study of the influence mechanism of postdoctoral career growth and proposes targeted strategies for academic institutions to improve support systems, promoting more effective career development pathways.

Impact of Teachers’ Commitment to the Relationship between Transformational Leadership and Sustainable Teaching Performance

In the field of education, ongoing processes, and optimal schoolwork outcomes require educational leadership, especially in developing countries, due to the lack of sustainable teaching performance and effective leadership. The present study aims to examine the mediating role of teachers’ commitment to transformational leadership and sustainable teaching performance. The sample of the study was selected using a stratified random sampling technique. Out of the 450 copies distributed to the participants, only 374 were retrieved as valid. The hypotheses of the study were tested using PLS–SEM. The findings showed a positive effect of transformational leadership on teachers’ commitment. Moreover, transformational leadership was also found to positively impact teachers’ performance. In contrast, the teachers’ commitment was revealed to positively affect sustainable teaching performance. Finally, the study showed that the teachers’ commitment mediated the relationship between transformational leadership and sustainable teaching performance. This study is unique for being among the few studies that examine the effects of principals’ transformational leadership. It provides educational leaders and policymakers with significant insights by providing a roadmap that aids in understanding the most influential factors on teaching performance sustainability. Consequently, this study holds significant practical relevance for leaders in the field of education and policymakers, as they provide valuable insights into policies and practices that can be implemented to foster sustainability in the school environment.
