Grassroots football is a fundamental and essential part of professional football; therefore, the current research was conducted with the aim of presenting a grassroots football development model in Iran. The current research is applied in terms of purpose and mixed in terms of data collection. In the qualitative part, the systematic approach of grounded theory methods was conducted, and structural equation modeling was used to evaluate and validate the qualitative model. To conduct the interviews, faculty members and sports managers were studied through purposeful approach. In the quantitative part, the research samples included sports managers, coaches and players selected via convenience sampling. Based on the results, causal conditions include factors related to facilities and resources, human resources and managerial factors; context includes factors related to family, education and motivational factors; Intervening factors include economic-political and legal factors; the strategies include human resource management strategies, development of scientific management and coaching, synergy of related organizations and the use of income generation strategies. The consequences include the development of professional football and sustainable development through sports. According to the results of quantitative part, the validity of the research model was approved. the proposed model can be presented as a scientific framework and guidance based on the knowledge of experts for the country's sports managers in line with the development of grassroots football.

Purpose: The primary objective of this study was to develop a comprehensive model to enhance adjunct faculty collaboration at Islamic Azad University. The research focused on identifying key factors influencing adjunct faculty collaboration by exploring professional, organizational, and individual competencies. Methods and Materials: This study used a quantitative, descriptive-survey research design. The statistical population comprised all adjunct faculty members at Islamic Azad University, with a sample of 404 participants selected using multi-stage cluster random sampling, calculated through Cochran's formula. A researcher-made questionnaire with 95 items across three dimensions—professional competencies, organizational competencies, and individual competencies—was used for data collection. The reliability of the questionnaire was confirmed with a Cronbach’s alpha of 0.7. Data were analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to validate the proposed model. Findings: The results from EFA identified 12 key factors across the three dimensions, including service delivery skills, job commitment, teaching technology, scientific production, educational innovation, self-efficacy, job identity, foresight, service to society, organizational ethics, participation in scientific development, and support and backing. The CFA confirmed these findings, with self-efficacy and teaching technology emerging as the most significant factors within individual and professional competencies, respectively. The R² values indicated strong correlations between the identified factors and adjunct faculty collaboration. Conclusion: The

Background and Theoretical Foundations: During natural and man-made crises and hazards, global pharmaceutical supply chains have experienced fluctuations in demand, production capacity issues, and distribution problems. The prevention and management of these challenges are crucial for maintaining public health, as the scarcity of essential medicines, vaccines, and blood products can pose severe health risks and hinder medical care. The present research aimed to develop a model of pharmaceutical cold logistics management during and facing maritime crises. Following a practical objective, this study is exploratory-descriptive in nature and benefits from a mixed methods design. Methodology: The statistical population of the research includes academic and military experts in the field of Supply Chain Management and Maritime Crisis Management. They involve 20 in the qualitative phase using purposive sampling and 120 constitute samples in the quantitative phase using convenience sampling. The qualitative phase was run through conducting semi-structured interviews, and a questionnaire was administered in the quantitative part. Data were qualitatively analyzed through thematic analysis, and a partial least squares (PLS) structural equation was run to quantitatively analyze the questionnaire. Findings and conclusion: Results showed that the drug cold logistics management during the crisis includes the main themes of the application of emerging technologies, information and communication management, pharmaceutical supply and distribution management, quality and trust management, and pharmaceutical supply chain audit. Based on the quantitative findings, the structural model of the research was approved, possessing sufficient validity according to the quality indices. Finally, the results of ranking the dimensions of the research based on the Friedman test showed that the application of emerging technologies in the management of maritime crises had the highest importance, and the pharmaceutical supply chain audit was found to be the lowest priority in the management of maritime crises.

Background and Theoretical Foundations: One of the dual challenges in the world of organization and management is job engagement versus job burnout. Some believe that job engagement is the positive antithesis of job burnout. Job burnout is a problem in modern societies related to living in an advanced world, particularly in the modern work environment. Researchers have identified some consequences of this phenomenon as decreased motivation, dissatisfaction, and the intention to leave the job. The main objective of this research is to examine and compare the impact of job engagement and burnout (based on the Job Demands-Resources model) on the turnover intention among seafarers. Methodology: This research is applied in terms of its objective and descriptive-survey in nature. The statistical population consists of 300 employees working in maritime organizations in Mazandaran province, with a sample size of 169 selected through random sampling based on the Krejcie and Morgan table. To measure the research variables, questionnaires were used for job demands (role conflict, job conditions, and work-home interference) from Rizzo et al. (1970), Mohammadi et al. (2011), and Wagena & Geurts (2000) with 15 questions; job resources (supervisor support, self-esteem, and feedback) from HSE, Rosenberg (1965), Hackman & Oldham (1975) with 11 questions; job burnout (exhaustion, cynicism, and professional efficacy) from Maslach (1996) with 10 questions; job engagement (vigor, dedication, and absorption) with 12 questions; and turnover intention from Cammann et al. (1979) with 3 questions. Their validity was calculated using content and face validity methods, and their reliability was confirmed by calculating Cronbach's alpha. For data analysis, demographic information (descriptive statistics) was used, and for inferential analysis, correlation tests and structural equation modeling were employed. Findings and conclusion: Statistical data analysis indicates that the impact of job resources, job demands, and job engagement on job burnout are 0.81, 0.60, and 0.30 respectively; the impact of job resources on job demands and job engagement are 0.92 and 0.70 respectively; the impact of job engagement on job burnout is 0.30; and the impact of job engagement and burnout on employees' intention to leave are 0.30 and 0.72 respectively. The research results showed that job burnout and engagement affect seafarers' turnover intention. Additionally, job engagement and demands impact burnout, while job resources influence engagement. Job demands affect seafarers' burnout, and the relationship between demands and resources as well as the impact of job resources on job burnout was confirmed.
