Method: The research method chosen was meta-analysis in which all research reports were collected by using internal and external information data bank. Some twelve studies from throughout of Iran (2004-2013) involving some 3015 participants were used in this meta-analysis. Data were analyzed using Pearson coefficient effect size method for fixed effect model. All statistical operations accomplished by Comprehensive Meta-Analysis, Version 2.0. Results: results showed that the mean of mixed- model of effect size was 0/496 for fixed effect model and 0/497 for random effect model in which both were significant in 0/001 level. The mean of mixed- model of effect size (0/496) in this research showed the moderate to high on creativity. Conclusions: Also the results showed that there is significant effect size between cognitive styles, internal and external motivation, gender, emotional intelligence, epistemological believes, dimensions of goal direction, mental well-being, personality characters, teacher’s activity and characteristics, intelligence, age, parent’s marital satisfaction, critical thinking, happiness, thinking styles, and direction goal with creativity.

One problem associated with our contemporary modern life is the appearance of job stress in terms of the work environment. Meta-analysis creates a better understanding of the similarities and dissimilarities of the previous studies conducted in this field and hence allows for a more comprehensive perspective on the research subject. In the present study, the previous studies on the job stress have been classified in terms of such criteria as statistical society, the involved variables, and type of job, and finally 12 studies have been selected as the statistical society of the research. In our proposed meta-analysis, for investigation of the magnitude of the effect of the independent variables on the job stress, the criteria for the effect size of coefficients r and d of Cohen have been used. Our findings show that the variables for age (d = 0.49), gender (d = 0.56), and job experience (d = 0.35) have an intermediate importance in the amount of job stress. Besides, variables for organizational atmosphere (d = 0.62), organizational justice (d = 0.98), work ethic (d = 0.95), and job satisfaction (d = 0.8), each of which used in a separate study, have great importance in determination of the amount of job stress.

The research population comprised 50 dissertations, thesis and articles out of which a sample of 13 was purposefully selected to be analyzed. Expert consensus was employed to verify the identification reliability of the selection, categorization of the research data and the reliability of the coding system used. The significance and effect size reliability was checked via expert agreement of two meta-analyzers on effect size calculation. The results of the met-analysis revealed that intellectual capital was correlated with human resource productivity as a moderator variable. It was also found that among the 26 effect size figures calculated, 15 were high (< 0.5), four were low (from 0.1 to 0.3) and 7 were medium (from 0.3 to 0.5). Also, the results indicated that structural and human dimensions had respectively the greatest effect size with regard to their relationship with human resource productivity. Manuscript profile -

In order to identify the cause of this heterogeneity, by dividing the research based on different criteria for measuring information disclosure and market reaction and calculating statistics within the group, we found that these different measurement criteria used in research is one of the contradictory factors in research results. In the following study, observation of mandatory disclosure of financial and non-financial information as well as voluntary disclosure of financial information has a significant and positive relationship with market reaction.

Therefore, the purpose of this study is to use a meta-analytical research model to combine and integrate the results of studies on the relationship between social capital and crime prevention.Method: In order to perform the present meta-analysis, by examining the background of all the researches related to the relationship between social capital and crime prevention that were published in prestigious scientific journals between 1390 and 1399, 17 studies that It was methodologically acceptable, selection and meta-analysis were performed on them. The research tool was a meta-analysis checklist and Cohen's effect size method was used to achieve the overall correlation value.Finding and Conclusion: The results showed that the effect size or coefficient of effect of social capital on crime prevention is equal to 0.48 which by converting the mean d to the value of z in a normal distribution curve according to Cohen's interpretive system, this amount is considered a high effect. Be. In general, the results showed that social capital has a significant effect on crime prevention at the level of (P <0.001). Also, the magnitude of the effects of social capital variables can indicate their importance in crime prevention and guide future research and policy-making in this area. Manuscript profile -
