This study delved into the dynamics between social capital and human capital and their influence on the knowledge management practices of teachers in Tehran, Iran. The researchers adopted a random sampling method, selecting 214 participants, and administered three standardized questionnaires to collect data. Data analysis was conducted using the Structural Equation Modeling approach. The findings of the study revealed that social capital did not have a significant impact on knowledge management. The researchers attributed this to the presence of a weak culture of teamwork among Iranians, a subject they elaborated on extensively in their article. However, the second hypothesis indicated that social capital significantly influenced human capital, while the third hypothesis demonstrated that human capital had a substantial effect on knowledge management. The fourth hypothesis proposed that social capital influenced knowledge management through the mediating role of human capital, and this effect was found to be significant. These research findings highlight the distinct roles played by social and human capital in knowledge management, with human capital emerging as the more influential factor. Moreover, the study not only explored the direct relationship between social capital and human capital but also emphasized the mediating function of knowledge management within these associations. This novel perspective can enhance our comprehension of methods to enhance human capital within organizations by harnessing the potential of social capital and effective knowledge management

Purpose: The present research was conducted with the aim of expressing the challenges of transformational leaders in schools.Method: The approach of the current research is qualitative and the strategy used is narrative research.The researched population was all school principals of Kermanshah city.Sampling was purposeful and 13 people were studied until reaching theoretical saturation. Data collection was semi-structured interview and document review. Validation in the present research was examined and confirmed based on the process of verifiability, transferability, believability and reliability.Findings: The analysis showed that the challenges of transformational leaders in schools include different aspects. The participants reflected the challenges in the form of challenges of different definitions and perceptions, the need for capabilities and competences, and finally structural challenges, and these results were drawn in three graphs. Challenges related to the definition and characteristics include the following: common goals, planning, creating a professional work team, creating change and transformation and inspiring employees. In the challenges related to the necessary competencies of transformational leaders, we also found five main categories including: scientific support, emotional support, clear and two-way communication, organizational foresight, creating a creative and dynamic environment.In the structural challenges faced by transformational leaders, we also found four categories including: organizational issues, individual issues, socio-cultural issues and lack of resources and facilities.

Objectives: The present study aimed to investigate the relationship between active work behaviors, transformational leadership style, and work engagement of vocational school teachers with the mediating role of innovation culture using Structural Equation Modeling(SEM). Methods & Materials: This research is applied and correlational. The study population consisted of teachers of vocational school in Urmia city during the academic year 2021-2022, totaling 309 individuals. A sample of 200 teachers was selected using stratified random sampling and Cochran's formula. The data were collected using the Zopiatis et al. work engagement questionnaire (2014), Tornau and Ferse's active work behaviors scale (2013), Bass and Avolio's transformational leadership style scale (1995) and Dobni's innovation culture scale (2008). The validity and reliability of the instruments were confirmed. Structural equation modeling (SEM) was used to analyze the data using SPSS and AMOS24 software. Results: In this study, a model of relevant variables affecting work engagement was examined. The findings showed that innovation culture and active job behaviors have a direct, positive, and significant effect on work engagement. The direct effect of active job behaviors, transformational leadership style on innovation culture is positive and significant. Moreover, the mediating roles of innovation culture on work engagement were confirmed. Active job behaviors, transformational leadership style, affect work engagement through the mediating variable of positive and meaningful innovation culture.
