The proposed study is performed among 240 employees who work for Allameh Tabataba’i University in Iran. The study designs a questionnaire in Likert scale and distributes it among selected employees and, using structural equation modeling, investigates the role of social capital on job satisfaction as well as citizenship behavior. The preliminary results of our survey indicate that social capital positively influences on both mentioned variables.

Job satisfaction plays an essential role on the success of any organizations. In this paper, we present an empirical study to measure the effects of five factors including work conditions, pay, promotion, supervisor and co-worker on job satisfaction. The proposed study is performed among 130 employees who work for one of Iranian transmission electricity in Iran. The study designs a questionnaire in Likert scale and distributes it among selected employees and, at the same time, measured overall job satisfaction from other method. The results of testing different hypotheses indicate that all employees are satisfied from their job (t-student=3.243, P-value=0.01). The study also presents a method to find desirable weights for each component of job satisfaction.

Accounting conservatism limits managerial incentive and ability to overstate performance and hide bad news from investors, which, in turn, reduces stock price crash risk. This study examines relationship between conservatism on financial reports and risk of stock price crash. Using a sample of 54 listed firms in Tehran Stock Exchange over the period of 2006–2010 and panel logistic regression, we examine different hypotheses. The results indicate that accounting conservatism, as measured by Khan and Watts (2009) CSCORE [Khan, M., & Watts, R. L. (2009). Estimation and empirical properties of a firm-year measure of accounting conservatism. Journal of Accounting and Economics, 48(2), 132-150.], reduces the likelihood of a firm experiencing stock price crashes. The finding holds after controlling other variables such as: negative skewness of firm-specific-weekly return, standard deviation of firm-specific-weekly return, the mean of firm-specific-weekly return, detrend share turnover, size, market to book value of equity ratio, total debt ratio and return on asset ratio, but we did not observe any relationship between these variables during stock price crash.

Brands are considered as valuable assets of a company both economically and strategically. Thus, having customers who are loyal to a brand is one of the main goals of businesses companies. Identifying and anticipating the customers’ needs are vital to the enterprises gaining competitive advantage and market segmentation. Maintaining and enforcing customers’ loyalty is a strategic challenge for companies seeking to keep and promote their competitive status in the market. High brand loyalty of the customers generates competitive advantage for the company and it increases the income and decreases the costs of marketing. In addition to increasing the market share, loyalty allows to ask for higher prices compared with its competitors. This study seeks to investigate the factors influencing customer loyalty to sport brands. The statistical population of this research was Tehran city. Using simple cluster sampling, 502 customers of four known brand sports, i.e. Nike, Puma, Adidas, Reebok, and Fila were chosen. Furthermore, a questionnaire, which assessed seven variables including reputations, brand name, brand image, brand loyalty, customer satisfaction, promotion and the price was used and the hypotheses were analyzed using statistical tests such as Kolmogorov-Smirnov test (K-S test), Spearman correlation, simultaneous linear regression and binomial test. The findings suggested that the brand name has a strong correlation with brand loyalty. Moreover, variables such as reputation, brand image, customer satisfaction, price and promotions also have positive and significant effect on the brand loyalty.

Collaboration can be a very challenging process precisely because it is a highly intense way of working, requiring new ways of thinking, behavior and ways of operating. Cultural Intelligence (CI) is an antecedent for collaboration . The primary goal of this survey is to investigate the relationship between cultural intelligence of managers and their employees’ collaboration. This research is a descriptive-correlation study where 119 managers and 175 employees are selected by stratified random sampling from the Social Security organization managers and their workers. To measure cultural intelligence, the Iranian version of the cultural intelligence questionnaire is implemented and collaboration is measured using a questionnaire developed by the researcher. The Cronbach & apos; s alpha reliability coefficient respectively for cultural intelligence and collaboration questionnaires are 0.933 and 0.813, respectively, which are well above the minimum acceptable limit. Data collected using SPSS 19 and they are analyzed using LISREL 8.54 software packages. The results indicate a significant and positive relationship between cultural intelligence among managers and their employees’ collaboration. As the relationship between motivational and behavioral CI dimensions and collaboration is also determined to be positive and significant. Based on demographic factors such as gender, age and education we cannot comment on the cultural intelligence of managers and employee’s collaboration but having inter-cultural experiences has had a positive impact on the cultural intelligence of managers. Based on the findings obtained we can say that Cultural Intelligence is a key factor, influencing and determining for collaboration.

We used a researcher-made questionnaire for data gathering. The Cronbach's alpha for this questionnaire was .88 and split-half reliability was .80, which represents for a reliable questionnaire. Furthermore, we used content validity and confirmatory factor analysis to confirm the validity of questionnaire. Data analysis was accomplished by structural equation modeling using the LISREL software v 8.7. Research results indicate that the effect of role ambiguity on work-family conflict is statistically significant (p-value = 62.40). Furthermore, the effect of role ambiguity on job stress was confirmed with significance of 1.83. On the other hand, the effect of role conflict on work-family conflict was not confirmed, because its significance value was negative. However, it was found that the job stress is influenced by role conflict (p-value = 2.35). And finally, the effect of work-family conflict on job stress was confirmed with the number of .93 for its significance value.
