To collect data, Beliefs in a Just World Scale (BJWS) and Life Orientation Test (LOT-R) were applied. To analyze the obtained data, the Pearson correlation coefficient and stepwise regression analysis were used.
The obtained results indicated that optimism (a dimension of life orientation) was significantly and positively correlated with beliefs in a just world for self (P Overall, the results of the current study showed that beliefs in a just world for selfwas significantly and positively correlated with optimism and was a predictor of optimism among university students.

The sample size was n=750 of which 352 (47%) were female and 395 (52.7%) were male, which were selected via multistage cluster sampling. But as a result of improper answering to some questionnaires the number decreased to 270 for females and 283 for males. In order to collect the data a demographics questionnaire, Millard and Joseph's (2000) bullying victims scale, Atashi's (1387) parenting styles scale, and Offer's (1989) Self-image scale were used.
Results from hierarchical regression analysis showed that in females there was a significant negative relationship between all the subscales of dealing with bullying except the “relational violence” subscale with age, and in males there was a negative relationship only between the “teasing” subscale and age. Parenting styles had significant relationships with Self-image and had a negative relationship with dealing with peer bullying

Data collection tools consisted of the Inventory of perfectionism, Measure of guilt and shame proneness and forgiveness questionnaire. For analyzing the research model, path analysis in Amos software was used. Results showed that positive and negative perfectionism predicted self forgiveness both directly and indirectly through shame and guilt feeling. Components of perfectionism predict self forgiveness through guilt feeling positively and through shame feeling negatively. Conclusively, results of this study showed that guilt feeling has a compatible role in moral behavior like self forgiveness.

In order to validating this scale, methods of Cronbach's alpha and test-retest reliability in 3 weeks were used for reliability and ostensible validity, concurrent convergent and divergent validity and finally confirmatory factor analysis were used by SPSS-21 and Amos-21.
Findings: internal consistency of items by Cronbach's alpha was 0.83, test-retest reliability was equal to 0.90. Convergent validity with prosocial behavior scale was 0.50 and divergent validity with loneliness scale was 0.42. Goodness of fit indicators of confirmatory factor analysis was desirable (X2= 22.63, df= 9, RMSEA= 0.07, GFI= 0.96).

The instruments which used in this research were workplace ostracism Ferris (2008), psychological capital Luthans (2007), job stress Parker & De Cotiis (1983), turnover intention Camman, Fichman, Jenkins & Klesh (1979) and job performance Paterson (1970) Questionnaires. Data were analyzed by Pearson correlation and moderated hierarchical regression. Finding: Results showed that workplace ostracism positively correlated with job stress and turnover intention, and negatively correlated with job performance. Furthermore, moderated regression analysis showed that psychological capital moderated these relationships significantly. On the other hand the moderator role in the analysis of the results showed that workplace ostracism in staff that has lower-level on psychological capital, compared with employees who have higher psychological capital, has a stronger relationship with job stress. Also workplace ostracism in staff that has lower-level on psychological capital, compared with employees who have higher psychological capital, has a stronger relationship with turnover intention. And also workplace ostracism in staff that has higher-level on psychological capital, compared with employees who have lower psychological capital, has a weaker relationship with job performance. human is a social creature and a healthy and successful human characteristics, is skills and ability to communicate effectively and constructively with others.
