The purpose of the present study is to review the effect of using social media on the social identity and job performance of employees in the sport organization of Tehran municipality. This is a descriptive-correlational study which was conducted as field research by questionnaires. According to the obtained information, there are 1360 employees in the sport organization of Tehran municipality in 2021. Based on the Morgan Table, 302 members were chosen as the research sample. For data collection, Jahānbāni’s questionnaire (2018), Richard Jenkins’ social identity survey (2008), and job performance questionnaire designed by Kumpz et al. were used. Descriptive statistics was used to classify raw scores, design frequency distribution tables and measure dispersion indexes such as average, standard deviation, and frequency. The results showed that using social media is effective on the social identity and job performance of employees in the sport organization of Tehran municipality. Thus, it is recommended to create a special database and register the employees’ requests with the purpose of understanding their needs and expectations in social networking. Besides, it is suggested to have dialogue with the employees through practical programs in social media in order to improve their performance.

The aim of this research was to predict procrastination based on empowerment among the employees of sports and youth departments in Kermanshah province. The statistical population included all employees of sports and youth departments of Kermanshah province (400 people), among whom 123 people were randomly selected based on Morgan's table. Badie et al.'s procrastination questionnaire (2011) and Marquardt's employee empowerment questionnaire (2018) were used to collect the data required for the research. Independent t-test and one-way analysis of variance were also used for comparison between groups, Pearson's correlation coefficient test was used to examine the relationship between variables, and standard regression test was used to predict procrastination based on ability at a significant level (p≤0.05). Based on the results of the research, the average score related to procrastination was significantly lower than the hypothetical average value and the average score related to empowerment was significantly higher than the hypothetical average value. The difference in the scores of empowerment, procrastination and its sub-scales, taking into account the gender, marital status and age of the employees, was not significant (p≤0.05). There was a significant negative relationship between empowerment, procrastination and its subscales (p=0.001). Also, the results showed that part of the employees' procrastination can be predicted based on their empowerment. The results showed that the amount of procrastination decreases with the increase of ability. The findings show that the employees of sports and youth departments avoid procrastination in their behavior in a relatively appropriate manner and are in a good and appropriate situation in terms of empowerment.

The purpose of the present study is to review the condition of Sarāy-e Mahallat's utility indexes from the view of citizens in Tehran. The research statistical sample consisted of all 101 male and 117 female participants in the gyms of Mahallat. The research method was descriptive and its purpose was practical. The measurement instrument was a research-made questionnaire distributed among the statistical population after receiving the expert comments about its validity. After collection, its reliability was reported to be (–r 0.89.9) by Cronbach's alpha test. The research results showed that the citizens rated the sport equipment's safety to be weak. They had more expectations of the gym halls, equipment's safety and variation, expert coaches, and sport groups. Furthermore, the population under study evaluated the total satisfaction of Sarāy-e Mahallat to be less than average and it decreases as more participants join the gyms. No significant difference was observed between men and women in this regard. The most important obstacles and limitations for the participation in Sarāy-e Mahallat include the participants' lack of time and the fact that all classes were not active there.

The purpose of the present study is to compare resting levels of Interleukin-6, Tumor Necrosis Factor-Alpha, and some portions in the immune system of athletes and non-athletes with spinal cord injury. Convenience sampling was used in this study and accordingly 10 non-athletes and 10 athletes from different fields were chosen. For testing the immune system, the number of white blood cells (lymphocytes, monocytes, and neutrophils), and for testing inflammatory indexes, resting levels of Interleukin-6 and Tumor Necrosis Factor-Alpha in the blood serum sample were measured. For measurement of blood parameters, ELSA method and the special kit were used. Descriptive statistics was used for data explanation/description and inferential statistics was used to explore the research results. Independent t-test was applied for the comparison between the research variables related to two athletic and non-athletic groups. The results revealed that there is no significant difference between athletes and non-athletes in Interleukin-6 (p=0.859), Tumor Necrosis Factor-Alpha (p=0.539), and the number of white blood cells (p=0.942). It seems that exercising is not considered as a threat for the immune system of those who have spinal cord injury although more research is needed to explore the effect of sport on the immune system of such patients.

The purpose of the present study is to review the correlation between organizational learning and organizational entrepreneurship through work engagement among workers in the administration of sport and youth in Fars province. The statistical population under study consisted of 114 workers in the administration of sport and youth in Fars province among whom 90 members were chosen as the sample of study by total sampling. In terms of nature and purpose, this research was practical. For data collection, three questionnaires including Margaret Hill's Organizational Entrepreneurship (2013), Neefe's Organizational Learning (2001), and Schaufeli & Salanova's Work Engagement (2001) were used.  Using Cronbach's alpha coefficient, the reliability of the questionnaires was calculated to be 0.926, 0.873, and 0.851 respectively which were all confirmed. The research method was practical, descriptive, and correlational. The collected data were analyzed by Pearson correlation, regression analysis, structural equations, and some software like SPSS and PLS. The results of Pearson's correlation showed that there is a significantly positive relation between organizational learning, work engagement, organizational entrepreneurship, and their components. Besides, the results of regression analysis revealed that learning culture form among organizational learning components and energy from among work engagement components have the highest power to predict organizational entrepreneurship. Furthermore, learning culture form among organizational learning components has the highest power to predict work engagement. Finally, the interdisciplinary role of work engagement in the relationship between organizational learning and entrepreneurship was confirmed.

The purpose of the present study is to review the effect of self-management on the quality of life with the intervention variable of sport participation of male high school students. The purpose of this research was practical and it had causal methodology conducted through field method. The research population under study consisted of all male high school students in Mobarakeh (5000 members) among whom 357 students were chosen by Cochran formula and stratified random sampling. Data collection instruments were standard questionnaires including Parental Monitoring Scale (1991) and World Health Organization Quality of Life Scale (1996) as well as sport participation variables. Data analysis was conducted in both descriptive and inferential sections by SPSS (version 26) and SmartPLS 3. The results showed that there is a significantly positive correlation between parental monitoring and quality of life (p=0.000) and sport participation and quality of life (p=0.001); however, no relation was observed between parental monitoring and sport participation (p=0.907). Furthermore, the research conceptual model indicated the direct effect of parental monitoring on the students’ quality of life although the intervening role of sport participation was not confirmed in this model.
