The link between shared leadership and employee creativity has been consistently labeled as positive in prior studies, discounting a possible negative relationship. A parallel mediation model was constructed to establish the favorable and unfavorable outcomes of shared leadership on employee creativity. The model is based on the job demands–resources model that originates from conservation of resource theory. Psychological safety and role stress play positive and negative mediating roles, respectively. The theoretical model was validated using data collected from 232 employees of 42 teams in China. Empirical results demonstrate (a) a positive association between shared leadership and employee creativity through psychological safety and (b) a negative one through role stress. These relationships have theoretical and practical implications.

Teachers' professional learning community, as an effective path to promote teachers' professional development and elevate teaching quality, has been widely used in school contexts. In preschools, the practice of teachers' professional learning community mainly focuses on the curriculum in early childhood education. The revision and adaptation of the scale of the professional learning community for preschool teachers in the Chinese cultural context are of great significance for understanding the current situation of the professional learning community for preschool teachers and improving the quality of collaboration within the community. Teachers' Professional Learning Community scale was revised into the Curriculum-Based Professional Learning Community scale according to the characteristics of the curriculum in early childhood education in the Chinese context. Based on the data from a sample of 2,823 teachers, the study conducted an item analysis and exploratory factor analysis (EFA) on participants from sample A (N = 1,410) and confirmatory factor analyses (CFAs) on participants from sample B (N = 1, 413). Short-form Teacher Self-Efficacy scale was used as the criteria-related validity instrument. Sample A and sample B were used to explore the relationship between various dimensions of teachers' professional learning community and teachers' teaching efficacy. The results showed that instead of the five-factor structure of the original PLC scale, the Chinese version of the CBPLC scale consists of four factors: Shared Sense of Purpose, Collective Focus on Children Learning and Development, Collaborative and Reflective Activity, and Deprivatized Practice. The revised scale has high reliability and validity and can be used as an effective tool to measure the curriculum-based professional learning community of preschool teachers in China. The results of CFA indicated that the four-factor CFA model fit the data well, and the CBPLC significantly and positively predicted teachers' self-efficacy including instructional strategies, students' engagement, and classroom management.

Based on work-family border theory and work-home resource theory (W-HR), this paper examines the impact of border keeper’s support (organizational support and family support) on work-family enrichment and whether or how work-family boundary flexibility mediates the relationship between border keeper’s support and work-family enrichment. A sample of 504 preschool teachers in Guangdong province, China completed questionnaires. The research results show a two-way process of work-family enrichment for preschool teachers in China. Organizational support was directly and significantly correlated with work-to-family enrichment (WFE), and family support was significantly and directly correlated with family-to-work enrichment (FWE). Organizational support had no significant positive predictive effect on work boundary flexibility which has a significant positive predictive effect on WFE. Family support had a significant positive predictive effect on family boundary flexibility which had a significant positive predictive effect on the FWE. In addition, the study found that family boundary flexibility mediates the relationships between family support and FWE whereas work boundary flexibility did not mediate the relationships between organizational support and WFE. The above research results are partly consistent with the existing research, and partly inconsistent, which is related to the profound influence of traditional culture in Chinese society and the current situation of preschool teachers in China. Such findings have important implications for improving the work-family enrichment of preschool teachers.
