The population of the study, 470 employees of Payame Noor University in Kermanshah province, are included. Using Cochran formula, 212 people were selected. Materials and method: Data collection tools, questionnaires Diamond Levitt, and knowledge management researcher, and organizational effectiveness Parsons (1969). Questionnaire, approved three professors, and reliability with Cronbach's alpha for diamonds Levitt, knowledge management and organizational effectiveness, respectively (86%, 82% and 77%) are. Findings: By SPSS and LISREL, research data were analyzed. The results of the analysis and stepwise linear regression, 95% indicated that the diamond Levitt knowledge management variables (0.226), and organizational effectiveness (0.227) and knowledge management and organizational effectiveness (0.178), have a significant positive effect. The results of the study showed that, in effect Diamond Levitt knowledge management, organizational effectiveness as a mediator (0.263) is. Discussion: Also in this study to test the conceptual model, structural equation modeling was used, the results of direct effects diamond variable Levitt, knowledge management, (0.87) and organizational effectiveness (0.66), and the direct effect of knowledge management on organizational effectiveness (0.52), and the indirect effect and the effect of variable diamond-Levitt, organizational effectiveness, respectively (0.69) and (0.11) is indicated and the t-statistic is also witness to the significance of the results is. Finally, the mediating role of knowledge management, the relationship between the Diamond-Levitt, and was supported organizational effectiveness, so that the diamond Levitt indirect impact on organizational effectiveness, with the role of knowledge management (indirect effect = 0.69), Levitt diamonds larger than the direct impact on organizational effectiveness (direct effect = 0.66) is. The above results indicate fit (RMSEA = 0.072 and GFI=0.93) was the optimal model.

Purpose: The purpose of this study was to investigate the relationship between the job intelligence, job burnout and happiness among the high school principals in Zahedan City, district 1. Methodology: The research method is descriptive-correlational and the statistical population of this study is all the principals of district 1 high schools who worked in the academic year 2012-2013. The sample size was also equal to the population size (100 ones). To collect the data, Schering's Emotional Intelligence Questionnaire, Maslow Job Burnout Questionnaire and Oxford Happiness Questionnaire were used. One-sample t-test, Pearson correlation coefficient and stepwise multivariate regression were used for data analysis. Findings: It was concluded that there was a significant negative relationship between the emotional intelligence and job burnout, and there is a significant positive relationship between emotional intelligence and happiness. There is a significant negative relationship between all components of emotional intelligence of principals with their burnout. Among all components of emotional intelligence, two components of self-control and social skills had a significant positive relationship with the happiness of school principals. Among the components of emotional intelligence, the components of social consciousness and social skills can predict the job burnout of school principals. Also, among the components of emotional intelligence, social skills, self-awareness, self-control and self-motivating, can predict the happiness of school principals. Conclusion: The mean scores of all three emotional, happiness and burnout variables were less than the hypothetical mean among the principals.

The purpose of this study was to determine the efficacy of acceptance-based treatment and commitment to interdependence, loneliness and Attributional styles of addicts' wives. The present study was a quasi-experimental design with a pretest-posttest with control group and from the perspective of the purpose, the research was applied. The statistical population of the study consisted of all wives of drug addicts in Tehran. The sample of the present study was based on objective sampling based on available sampling including 30 subjects (15 subjects in each group, 15 in the experimental group and 15 in the control group). The research instruments were Spen-Fisher questionnaire (1991), loneliness questionnaire, Attributional style styles, and adherence-based therapy package. Data were analyzed by repeated measures of covariance and Bonferrini test. Findings showed that considering the fact that the level of significance is smaller than α, also considering that the effect of pre-test was covariate by covariance test, it can be concluded that in the context of the variables of dependency, loneliness and Attributional styles, Treatment based on admission and commitment has been significantly effective. Also, considering all the three variables, we can conclude that the experimental intervention has led to changes in the experimental group. So the treatment affected the decrease in dependency and loneliness and the change in the Attributional style.
