This paper presents an empirical study to investigate the effect of organizational climate on organizational citizenship behavior in one of Iranian automakers. The proposed study uses a standard questionnaire for measuring organizational citizenship behavior, which is adopted from Podsakoff et al. (2000) [Podsakoff, P. M., MacKenzie, S. B., Paine, J. B., & Bachrach, D. G. (2000). Organizational citizenship behaviors: A critical review of the theoretical and empirical literature and suggestions for future research. Journal of management, 26(3), 513-563.]. The study also uses another questionnaire, which measures organizational climate, which is adopted from Arabac? (2010) [Arabac?, I. B. (2010). Academic and administration personnel & apos; s perceptions of organizational climate (Sample of Educational Faculty of F?rat University). Procedia-Social and Behavioral Sciences, 2(2), 4445-4450.] and both questionnaires are designed in Likert scale. Cronbach alphas for organizational citizenship behavior and organizational climate are measured as 0.78 and 0.84, respectively, which are above the acceptance level of 0.70. Therefore, we can confirm the validity of both questionnaires. The study is implemented among 200 experts in Iranian automaker, randomly and using Spearman correlation ratio as well as stepwise regression techniques, the study has detected a meaningful relationship between components of organizational climate and organizational citizenship behavior.

This paper investigates the effects of different factors influencing on supplement of currency in Iran and the likelihood of currency crises.

The study designs a questionnaire in Likert scale, distributes it among some experts in tile industry. Using Pearson correlation test, the study has detected that there was a positive and meaningful relationship between marketing planning and the success of tile industry (r = 0.312 Sig. = 0.001). However, there is not any meaningful relationship between low cost production and success of tile industry (r = 0.13 Sig. = 0.12) and, there is a positive and meaningful relationship between organizational capabilities and success of tile industry (r = 0.635 Sig. = 0.000). Finally, our investigation states that technology and distributing systems also influence on the success of tile industry, positively.
