Purpose: the aim of the present research was to present an aggression prediction model in teenagers based on family cohesion and communication patterns with the mediating role of resilience. Methodology : this cross-sectional study was of correlation type. The research population consisted of second grade high school students of Tehran city in academic year 2019-2020. The research sample consisted of 500 individuals chosen through multistage cluster sampling method. They responded to the following instruments: Novaco Anger Scale and Provocation (Novaco, 1986), communication patterns (Ritchie and Fitz Patrick, 1990), family cohesion (Olson et al., 1985), and resilience (Connor and Davidson, 2003). The data were analyzed by Pearson correlation coefficient and structural equations modeling in SPSS and AMOS 22. Findings : the results showed that the aggression prediction model in teenagers based on family cohesion and communication patterns with the mediating role of resilience had good fit. Further, conformity-oriented communication pattern did not have a direct significant effect on resilience and aggression in teenagers and indirect significant effect with the mediating role of resilience on aggression in them (P>0.05). However, the conversation-oriented communication pattern and family cohesion had a direct significant effect on resilience and aggression in teenagers as well as indirect significant effect with the mediating role of resilience on aggression in them (P<0.05). Conclusion : according to the obtained results, for reducing aggression in teenagers, the extent of conversation communication pattern and family cohesion can be promoted in them through organizing educational workshops.

Purpose: The purpose of this study was to design a biorhythm management model for Iranian public school principals with a fuzzy Delphi approach. Methodology: The design of the present study was qualitative with fuzzy Delphi method. Statistical population, professors of organizational behavior management in universities of Mazandaran province and senior managers of education departments in cities of Mazandaran province were selected and four rounds of fuzzy Delphi technique were performed with their cooperation. This selection and interviewing continued until the theoretical saturation was reached. Using the "rich information" sampling method with 15 professors of organizational behavior management in the universities of Mazandaran province and senior managers of education departments in the cities of Mazandaran province, the required information with semi-structured questionnaires Collected in four rounds. SPSS software was used to analyze the data. Findings: The results showed that the biorhythm management model of Iranian public school principals has four cycles and 28 dimensions of physical cycle (physical) (high mobility and energy, high physical strength, physical endurance and stability, physical weakness (negative), decreased physical ability (negative), inactivity and lethargy (negative), doing useful work and extreme fatigue (negative) ), Emotional cycle (interest in work and life, kindness, immorality and temper (negative), irritability (negative), confusion and mental weakness (negative), love of others, the power of creativity in affairs and mobility in Against the behavior of others (negative), intellectual cycle (mental) (rational) (promotion of intelligence, comprehension and memory, forgetfulness (negative), mental laziness (negative), poor decision-making power (negative), thinking power in affairs , Gaining new ideas and not focusing on personal and work affairs (negative) and intuitive cycle (inner inspiration, strong sixth sense, absorbing negative energy (negative) and attracting the spiritual forces of nature). Conclusion: Investigating the effect of biorhythm and different situations of employees on their job performance is an important issue and should be considered to prevent problems and increase performance, so identifying the explanatory dimensions of biorhythm management among managers of educational organizations, according to their critical tasks, is very important. And it seems necessary
