Purpose: The quality of education and research is one of the concerns that academic systems always strive to achieve. Undoubtedly, the existence of leading professors with appropriate scientific and ethical competencies is one of the effective fundamental factors in the quality of higher education systems. Methodology: The general purpose of the present study is to examine the dimensions of leading professors and determine the importance and priority of these goals. In terms of purpose, this research is an application that was done with a mixed approach (qualitative and quantitative) with an exploratory design. In the qualitative approach, the content analysis method was used and in the quantitative approach, the descriptive survey method was used. The statistical population consisted of 20 professors of Babol University of Medical Sciences in the qualitative department and 348 faculty members of Babol University of Medical Sciences in the quantitative department. Taking the saturation law, 10 people and in the quantitative part, based on Cochran's formula, 183 people were selected as a statistical sample using stratified random sampling method based on scientific rank. By analyzing the qualitative data, a researcher-made questionnaire designed by leading professors with 80 questions was designed. Data were analyzed by structural equation modeling in SPSS-23 and PLS-2 software. Findings: The results showed that; Leading professors have three dimensions: "educational, research and individual". Conclusion: Educational dimension with five components (teaching skills, educational technology, education management, evaluation skills and observance of educational rules), research dimension with two components (scholarship and research ethics) and individual dimension with five components (characteristics Appearance is professional ethics, honesty, creativity and discipline) which has a greater impact on the educational dimension with a factor load of 0.963 and a research dimension with a factor load of 0.894.

Purpose: The concept of teacher competency is one of the key concepts in the document of the fundamental transformation of education. Different researchers have presented three approaches in various terms for modeling competency such as adaptive approach, adaptive-design approach, and design approach. Top-down and bottom-up approach is another division of competency modeling. Methodology: The present study is operational in terms of purpose and the method of collecting its data, is mixed. In this way, the first part of the present study is descriptive-correlation because this study aimed to collect the necessary information for determining the teachers' competency indicators and is qualitative research method such as content analysis method to extract the components from the top-level documents contained in the document of the fundamental transformation of education. Findings: On the other hand, since one of the research goals is to extract a questionnaire to determine the indicators and attributes of teachers based on the high education documents, quantitative research methods and factor analysis methods such as exploratory and confirmatory factor analysis were used. Conclusion: Overall, the result of the present study shows that each competency is a complex combination of motivation, mental ability, practical knowledge and practical skill that increases the probability of a person's success in a certain role, which is clearly tangible, and the existence of it ensures him for the acceptance of responsibility of that role.

The purpose of the present study was to model the structural relationships of job stressors and teachers' autonomy support with mediation of emotional exhaustion. This research was descriptive of the correlation type by the method of structural equations. The statistical population included all the teachers of first and second grade of secondary schools in Noor’s and Chamestan’s public schools in the academic year of 2019-2020, that based on Cochran’s formula and stratified random sampling method, 240 people were selected. The tools of this research were the job stressor factors questionnaire of Otero-Lopez et al. (2006), the teacher as social context questionnaire Welborn et al. (1992) and the teachers’ burnout inventory of Maslach et al. (1996). All analyzes were done by structural equation modeling method. The findings indicated that the structural relationship model of job stressors and teachers' autonomy support with the mediation of emotional exhaustion in teachers of first and second grade of secondary schools has favorable fit and significance. In this research, all the direct and indirect paths that lead to the prediction of teachers' autonomy support have been significant. The research’s results indicate that job stressors have a direct and indirect effect, through emotional exhaustion, on teachers' autonomy support and also emotional exhaustion directly affects autonomy support. Addressing these variables can be effective in solving the problems of teachers' autonomy support and increasing it.

Purpose: Today, the issue of academic failure is one of the most important and scrutinized factors in educational systems and examining the effective factors on it can help in better understanding this phenomenon and providing solutions to its reduce. Therefore, the current research was conducted with the aim of modeling the academic failure of senior students based on the socio-economic position and family social capital with the mediation of family chaos. Methodology: This study in terms of purpose was applied and in terms of implementation method was quantitative from type of correlational. The population of the present research was the senior students of Mazandaran province, which 170 people of them were selected as a sample by cluster sampling method. The research tool was a researcher-made questionnaire of effective social factors on academic failure, which had four components of academic failure, socio-economic position, family social capital and family chaos. The face validity of the questionnaire was confirmed by education specialists and experts and its reliability was obtained with Cronbach's alpha method above 0.70. The data were analyzed with tests of regression and structural equation modeling from type of path analysis in SPSS and LISREL software. Findings: The findings showed that all three variables of socio-economic position, family social capital and family chaos separately had a significant correlation with the academic failure of senior students and were able to predict the 31.0%, 20.2% and 22.9% of the changes of their academic failure, respectively. Also, all the three mentioned variables together could predict 51.6% of the changes of academic failure of senior students. In addition, the academic failure model of senior students based on the socio-economic position and family social capital with the mediation of family chaos had a good fit, and in this model, the variables of socio-economic position and family social capital on family chaos and academic failure and the variable of family chaos on academic failure had a direct and significant effect and the variables of socio-economic position and family social capital with the mediation of family chaos had an indirect and significant effect on academic failure (P<0.001). Conclusion: According to the results of this study, in order to reduce the academic failure of senior students can provide the basis for improving the socio-economic position, increasing the family social capital and reducing the family chaos.
