The purpose of this study was to investigate the relationship between authentic leadership, job enrichment, and employee turnover among university staff, conducted through a descriptive-correlational research method. The statistical population consisted of all 659 employees of the Islamic Azad University, Zahedan Branch. Using the Krejcie and Morgan (1971) sample size table, a sample of 247 individuals was determined, and simple random sampling was employed. Data were collected using the Authentic Leadership Questionnaire by Walumbwa et al. (2008), the Job Enrichment Questionnaire by Dehghan et al. (2010), and the Employee Turnover Questionnaire by Ghasemkhani (2013). The results indicated a significant relationship between authentic leadership and its dimensions (self-awareness, relational transparency, internalized moral perspective, and balanced processing) with job enrichment and employee turnover. Furthermore, the regression results showed that 78% of the variance in job enrichment and 48% of the variance in employee turnover could be predicted by the authentic leadership variable. 

Objective: Insomnia, marked by difficulty falling or staying asleep, affects many students and contributes to increased worry, cognitive distortions, and depression, exacerbating their overall well-being and academic performance. This study evaluates the effectiveness of Mindfulness-Based Stress Reduction (MBSR) in reducing worry, cognitive distortions, and depression in students with insomnia symptoms. Method: The research utilized a quasi-experimental design with a pretest-posttest control group. The statistical population consisted of university students in Ardabil Province during the 2023-2024 academic year. A total of 34 students were purposefully selected based on predefined criteria (e.g., insomnia symptoms) and then randomly assigned to either the intervention group (n = 17) or the control group (n = 17). The research instruments included the Insomnia Severity Index (2001), the Penn State Worry Questionnaire (1990), the Cognitive Distortions Questionnaire (2004), and the Beck Depression Inventory (1996). The intervention group participated in eight weekly sessions of 90-minute MBSR, while the control group received no intervention. Data were analyzed using multivariate analysis of covariance with SPSS-27. Results: The results indicated that MBSR significantly reduced worry (F = 46.86), rejection in interpersonal relationships (F = 30.07), unrealistic expectations in relationships (F = 41.54), misperception in interpersonal relationships (F = 30.38), and depression (F = 41.20) among students with insomnia symptoms (P < 0.001). Conclusion: The results highlight the potential of MBSR as a valuable non-pharmacological intervention for managing insomnia and associated psychological challenges in academic settings. Given its effectiveness, further research could explore long-term benefits and applicability across diverse student populations and settings.

  Objective : Autism spectrum disorder is a complex neurodevelopmental disorder characterized by communication problems, limited social interactions, and repetitive behaviors. The present study aimed to investigate the effectiveness of play therapy education with a parent-child approach in improving social skills in children with autism spectrum disorder. Methods: This study was a quasi-experimental study with a pre-test-post-test design, a control group, and a follow-up phase. The statistical population of the study included children with autism at the Justice Center in Isfahan. The sample of the present study included 30 children with autism, including 30 children with autism, who were selected using purposive sampling and were divided into two experimental and control groups. The research instrument used was the Autism Social Skills Profile (ASSP), and play therapy education sessions with a parent-child approach were implemented in ten 90-minute sessions once a week on the experimental group. The research data were analyzed using repeated measures analysis of variance and Bonferroni post hoc test and SPSS version 24 software. Results: The research findings showed that the difference between the experimental and control groups in terms of the mean scores of social skills variables in all stages of the experiment was significant (P<0.001). Conclusion: The results of this study show that play therapy education with a parent-child approach can help improve children's social skills. Therefore, its use is recommended to strengthen social skills in children with autism spectrum disorder.

Aims: The present study aimed to validate the Persian Emoji Lexicon (PEL) and examine gender and cultural differences in the perception of the affective properties of selected emojis. Method: The study consisted of two phases: emoji selection and an online survey. First, we identified the 109 most frequently used emojis on Twitter. In the second phase, we assessed emotion and valence ratings from a sample of 200 X users (140 females; 27.3 ± 3.5 years). Results: Of the 109 selected emojis, 90 were perceived as having a positive valence. Gender comparisons revealed that women rated significantly higher emotional intensity across all eight emotion dimensions compared to men. We also compared our findings with a similar database validated among Canadians. The inter-rater reliability for emoji valence ratings between Iranian and Canadian participants showed a fair level of agreement (Kappa coefficient = 0.357), while also highlighting significant cultural differences in emotion perception. Conclusion: This database serves as a valuable resource for sentiment analysis of social media texts containing emojis, as well as for practical applications where emojis function as emotional cues to influence behavior (e.g., in marketing and education).
