Purpose: The aim of this study was to compare the effectiveness of transcranial magnetic stimulation (tms) and cognitive-behavioral therapy (cbt) in patients with depression in Tehran. Methodology: The purpose of the present study is to apply the pre-test and post-test with control group in terms of semi-experimental research method. The study sample consisted of 60 clients with depression who had been diagnosed by the Psychiatric Commission and admitted to psychology clinics in 2015. They were selected by random sampling and were randomly divided into three groups (two experimental and one control group) in each group of 20 persons. . Experimental groups in one group underwent cognitive-behavioral therapy for 12 sessions and the other group underwent transcranial magnetic stimulation for 20 sessions. Control group received no intervention. Data were analyzed using covariance analysis. Findings: The results showed that there was a significant difference between transcranial magnetic stimulation and cognitive-behavioral therapy in reducing depression in clients (P <0.01). Conclusion: Transcranial magnetic stimulation therapy and cognitive-behavioral therapy are effective in reducing depression in patients referred to psychiatric clinics.

Purpose: The purpose of this study was to investigate the causal relationship between parenting styles and academic self-handicapping by mediating role of meta-cognitive and perfectionism skills. Methodology: The statistical population of the study consisted of all the second grade secondary school students in studying the academic year of 2017-18, in Bojnourd. A sample of 350 students was selected using multi-stage cluster sampling. To collect the data,(a) Alabama Parenting Questionnaire (APQ),(b) Metacognitive Skills Questionnaire(MCSQ)(Dowson,Mcinerney, 2004), (c) Perfectionism Scale (Hewitt, Flett (1991) and (d) Academic self-handicapping Scale (ASHS) (Schwinger, 2014) were used. Pearson correlation coefficient and Structure Equation Modeling were used to analyze the data. Findings: Findings showed that parenting styles directly to academic self-handicapping was not significant, But through the mediating role of meta-cognitive skills and perfectionism was significant. and the hypothetical model had good fit. Conclusion: teaching of the metacognitive skills to students will reduce the academic self-handicapping, and the increaseing of perfectionism will increase the likelihood of academic self-handicapping in the students.

Purpose: The purpose of this study was to present a model of organizational empowerment based on knowledge management among employees of Sepah Bank branches in Tehran. Methodology: The present study was applied in terms of purpose, and in terms of data collection, it was a mixed research (qualitative and quantitative). The statistical population consisted of academic and organizational experts including senior managers of Sepah Bank in Tehran and the quantitative department included all employees of Sepah Bank in Tehran. Sample size was estimated in theoretical saturation (20) in qualitative section and 343 in quantitative section. Purposeful sampling and stratified random sampling were used for quantitative sampling. Data were collected through qualitative interviews and quantitative researcher-made questionnaires based on 5-point scale. The face and content validity of the questionnaire was confirmed by several experts, validity was calculated by means of variance mean and divergent validity was calculated by AVE. The reliability of the questionnaire was 0.968 through Cronbach's alpha. Data were analyzed using Cronbach's alpha, AVE, AVE root matrix, Kolmogorov-Smirnov test, confirmatory factor analysis, and one-sample t-test. Findings: The results resulted in the identification of 17 components and 66 indicators, including 14 affective components including trust, motivation, commitment, emotional intelligence, participation, communication, structure, education, culture, leadership, technology and reward and 3 affective learning components. Organizational, organizational entrepreneurship and performance, a moderating variable (personality traits) and knowledge management as independent variables affect organizational empowerment based on knowledge management. Other results showed that the status of identified components in organizational empowerment based on knowledge management is desirable. In addition, mechanisms, facilitators, and barriers to organizational empowerment based on knowledge management were also presented. Finally, a research model consisting of influencing factors, content phenomena (constituents, facilitators, barriers, and effective mechanisms for organizational empowerment based on KM) was presented and the degree of fit was confirmed by experts with 95% confidence. Conclusion: Choosing important and effective knowledge and capabilities in the organizational field and enhancing organizational skills is a very effective way of empowering organizational personnel that can lead to enhancing organizational efficiency and organizational integrity of an organization's personnel.
