The research method was Structural Equation Modelling (SEM) and the statistical population included all employees of Tehran Payame Noor University in 2022 where 301 people were randomly selected and completed questionnaires. For data collection, the researcher-made questionnaire was used with acceptable reliability and validity. The findings showed that internal control systems have a significant direct and indirect impact on the intensity of organizational performance and innovation at an error level of 0<0.05.

Abstract Abstract
The aim of the present study was to investigate the mediating role of organizational justice in the relationship between transformational leadership and succession planning in higher education. The research method was descriptive correlational. The statistical population of this study included all administrators (200 people) of Kharazmi University were selected by convenience sampling method. For data collection were used the three Questionnaire of succession planning (Kim, 2006), Bass & Avolio (2004) transformational leadership, and organizational justice (Niehoff, and Moorman1993). Data analysis was done by using structural equation modeling in AMOS And Spss-22 software. The results of structural equation modeling showed that the conceptual model of research with experimental data fits very well and organizational justice plays the role of a complete mediator in the relationship between transformational leadership and succession planning. Accordingly, the variable relationship between transformational leadership and succession planning through organizational justice was confirmed in the form of path analysis. Thus, the variable of organizational justice showed a facilitating role in the relationship between leadership and transformational leadership and succession planning. Also, the leading variable of transformational leadership had a direct and positive effect on the succession planning of administrators. It can be concluded from the results of the study that organizational justice in the university has a facilitating role in the development of succession planning programs. Thus, by adopting a transformational leadership approach at the university, organizational justice will be established at the university, and eventually the process of succession planning will be upgraded and developed.

Abstract The purpose of this study was to investigate the role of trust and collective efficacy mediators on the relationship between transformational leadership and teamwork. This research is applied in terms of the purpose and from the perspective of the method is a descriptive correlation. The statistical population consisted of all the staff of the General Directorate of Education in Hormozgan province, which was selected using the Cochran formula of 176 people and selected by stratified random sampling method in the form of 10 working teams. For collecting data, Boston Leadership Style Leadership Questionnaire, Michael West Teamwork Questionnaire, Zarei & Associates Organizational Trust Inventory and Chen Individual and Individual Self-Efficacy Questionnaire were used for data analysis. Structural Equation Methodology was used with PLS software. The results indicate that collective self-efficacy has a moderating role on the relationship between transformational leadership and team performance, but no such role was found for organizational trust.
