Introduction: The purpose of this study was to compare the resilience and responsibility of juvenile offenders in Tehran. Methods: The research method in this research is comparative Ali and the type of applied research. The statistical population of the study is delinquent and non-delinquent adolescents in Tehran (age range of 14 to 17 years). In this research, one of the centers for the upkeep of juvenile delinquents in Tehran was selected as the Rehabilitation Center of Tehran's Rehabilitation Center through sampling available to 85 offenders. The sample size was obtained by using Cochran formula for both non-delinquent perpetrators of a group of 70, of which 140 were in total. For data analysis, descriptive statistics and inferential statistics were used by SPSS software. Result: The results of the U-Mann-Whitney test showed that the level of resilience and responsibility among juvenile offenders is different. In other words, the average resilience outcomes show that delinquent adolescents have higher levels of resilience than non-delinquent adolescents. Conclusion: The average results of the delinquent adolescents' responsibility were lower than non-decent adolescents, thus it can be inferred that juvenile offenders are more responsible.

Background and Objective: Adolescence is a period characterized by numerous social, psychological, behavioral and physical changes that can lead to some social problems such as delinquency. The purpose of this study was to compare the cognitive emotion regulation and identity styles among delinquent and nondelinquent adolescents. Materials and Methods: The present study was of causal-comparative design. The statistical population of this study included all delinquent and non-delinquent adolescents in the city of Rasht in northern Iran in 2017, among which 120 adolescents were selected by convenience sampling method. Data were gathered via questionnaires of cognitive-emotion regulation and identity styles for data analysis. Data were analyzed using multivariate analysis of variance by SPSS version 20. Results: The mean (SD) age of the delinquent group was 16. 9 (3. 5) and the normal group 17. 1 (4. 6). The mean (SD) score of the cognitive emotion adjustment components was higher among the delinquent group: 18. 1 (2. 2) vs. 15. 6 (3. 6) for rumination and 12. 1 (1. 5) vs. 8. 9 (2. 5) for blaming others (P<0. 05). However, the mean (SD) scores of focus on planning and self-blame were higher among the normal group: 36. 1 (2. 6) vs. 30. 1 (4. 5) and 9. 1 (1. 6) vs. 7. 1 (2. 6), respectively (P<0. 05). There was no significant difference between the two groups in terms of other components of cognitive emotion regulation and identity styles. Conclusion: The study showed that the rumination and blaming others was more frequent among the delinquent group, while self-blame was more frequent among the normal group. The delinquent and normal group did not differ significantly in terms of other components of cognitive emotion regulation and identity styles.

The aim of the current study was to investigate and compare the family structure, parental monitoring and affiliation with delinquent peers among the male delinquent and non-delinquent adolescents. It has also considered the interactions between these factors. In this Cross-sectional study, 96 delinquent adolescents and 91 non-delinquent adolescents, chosen through a convenient sampling in Tehran, completed family structure, parental monitoring and affiliation with delinquent peers questionnaires. Data was analyzed using independent sample T-test, Chi square test and Pearson correlation coefficient. Given the results of the independent sample Ttest, the two groups were significantly different in terms of parental monitoring and affiliation with delinquent peers.Using Chi square test, the findings revealed that there was a significant difference between the delinquent and nondelinquent adolescents in terms of family structure.Moreover, adolescents in broken families in comparison to the adolescents in intact families reported less monitoring by their parents. The results obtained from the current study were in line with the results of the previous research and showed that distress in family structure, that weak parental monitoring and that affiliation with delinquent peers had a significant role in the delinquency phenomenon. Therefore, it seems necessary to consider these factors as the influential factors promoting delinquency.

Economic analysis of criminal law seeks to explain decision-making and behaviour of criminals and potential criminals so as to suggest strategies and mechanisms to decrease criminal behaviour. The thesis of this approach is that the criminals, because of uncertainty of consequences of criminal behaviour, seek to maximize their expected utility and use cost-benefit analysis. So increasing the severity or certainty of punishment can decrease crime rate. In this paper, this claim will be explained and criticized. I conclude that despite of empirical observations, economic man can explain happening of some crimes. Furthermore although the proportional effects of severity and certainty on crime reduction are not certain, in the battle against the crime, economic model can be a punishment-based complement to some of the criminology theories, specially, situational deterrence theory.
