The purpose of the research is to analyze the effects of ethical leadership and organizational politics on individual and team creativity, focusing on the mediating role of knowledge hiding. The study is a descriptive-correlational survey and is applied in terms of purpose. The statistical population included employees of selected public organizations in the Eqlid County, totaling 950 individuals. 270 individuals were selected using a non-probability convenience sampling method based on the rule of thumb for SEM as the sample. To collect data, the following measures were used: Brown's et al. (2005) Ethical Leadership scale, the Organizational Politics scale by Kacmar and Carlson (1997), the Knowledge Hiding scale by Serenko and Bontis (2016), the Individual Creativity scale by Zhou and George (2001), and the Hanke's (2006) Team Creativity scale. The validity of scales was confirmed using the content validity, and the reliability was examined using Cronbach's alpha, yielding values of 0.89 for the Ethical Leadership, 0.82 for the Organizational Politics, 0.92 for the Knowledge Hiding, 0.87 for the Individual Creativity, and 0.85 for the Team Creativity. For data analysis, SEM and the AMOS software were used. The results of the study fitted the research model, indicating that ethical leadership and organizational politics have a significant negative impact on knowledge hiding. Additionally, knowledge hiding has a significant negative effect on both individual and team creativity of employees. By reducing knowledge hiding behaviors through ethical leadership and organizational politics, the level of creativity among employees at both individual and team levels increases.

Objective: This study aimed to examine the effectiveness of neurofeedback in reducing symptoms of depression, anxiety, and stress in high school deaf girls. Method: A total of 24 deaf female students were randomly assigned to experimental (n=12) and control (n=12) groups. The experimental group received 15 neurofeedback training sessions targeting the F3 and F4 regions. Both groups completed the DASS-21 questionnaire before and after the intervention.. Results: Multivariate analysis of covariance indicated significant reductions in depression (F = 15.680, p<.05), anxiety (F = 5.991, p<.05), and stress (F = 6.100, p<.05) scores in the experimental group compared to the control group. Conclusion: Neurofeedback appears to be an effective intervention for improving mental health among deaf adolescents.

Multiple sclerosis (MS) is one of the most common neurological diseases. The disease is clinically defined by the involvement of different parts of the central nervous system (CNS) at various times. Its peak incidence is between the ages of 20 and 40. The experience of pain plays an important role in the mental health and quality of life of MS patients. Research also shows that if MS patients have high levels of self-compassion, they can more easily manage negative situations. This research aims to determine the effectiveness of mindfulness training programs on the perception of pain experience and self-compassion in MS patients. Method: >The current research is an experiment with available sampling methods. The sample includes 40 MS patients, 20 in the experimental group and 20 in the control group. Mindfulness training programs (Kabat—Zinn), the McGill Pain Experience Scale (MPQ), and the NF Self-Compassion Questionnaire (SCS-LF) were used to collect data. The data were analyzed through the statistical test of multivariate analysis of covariance (MANCOVA). Results: >The results showed that the average difference between the groups regarding pain experience (F=49.270) and self-compassion (F=51.249) is significant. Therefore, it can be said that increasing self-compassion leads to higher efficiency in facing stressful situations. Conclusion >: Enhancing cognitive processes, particularly self-compassion, through mindfulness training can significantly influence individuals’ perception of pain. It is recommended that families receive appropriate training to develop strategies aimed at strengthening mindfulness skills in individuals.
