The aim of this paper is examine the moderating role of organization commitment, organization climate and job satisfaction as organization internal factors on the relationship between organizational citizenship behavior and organization performance, using organ’s model in Tehran general office of physical educations. Organizational citizenship behavior is a useful set of behavior that is not listed in the job description but employees perform it while doing their tasks to help others. The method used in this paper is cross- sectional survey. The required in formation for the research were gathered in two ways: Library and questionnaire. The statistical population of the research are the employees of Tehran general office of physical education (472), from them 147 employees were selected randomly as sample. Spss was used to analyze data and to study the relationship between variables hierarchical regression analyze was used. The results indicate that organization internal factors moderate the relationship between OCB and of, collectively and individually.

In this research, it has been attempted to model the production line of reinforcement bars using discrete simulation modeling to determine the number of cranes required, considering the relevant factors such as, production line speed, failure rates of each machine and the space requirement. To achieve this, the production process was first investigated and an appropriate simulation model was formulated using the Enterprise Dynamics (ED) simulation package. The relevant data were then collected for each entity through time study. The sample size and the statistical distributions were identified. To check for model validation, the simulation results were compared with actual data using statistical tests. To determine the desired number of cranes and improve the production line performance, three indices i.e. output rate, productivity factor and mean waiting time were determined through expert opinion and eight different layouts were constructed as alternatives considering the space constraint. All three indices were determined through simulation taking a reproducible approach. The weights of the criteria were computed using the Entropy technique and the alternatives were ranked using the TOPSIS methodology.

Objective Influence dimensions of service quality in online stores (website design, reliability, trust, personalization, responsiveness) on the overall service quality, customer satisfaction and customer’s perception which lead to purchase intentions, was reviewed.Methodology descriptive (type of survey) study, society is people who have experienced online shopping. Sampling method was simple random sample, and sample volume was 385 person. Data collection tool was a questionnaire, and Cronbach’s alpha coefficient and Lisrel software is used For analyzing.Research results website design and Personalization in online store, have not influence on purchase intention. Trust, reliability, and responsiveness in an online store positively influences purchase intentions.Research Limitations non- cooperation some online shops for insert questionnaire in their stores, and Not commonly online shopping among people.Managerial Implications Managers of online stores to set up an online shop mostly focused to put customer’s confidence. Recommended to administrators of online stores is more attention on the security of their ownsaleswebsite.Originality/Value All stages of the research on the web and have been done online form.

This research empirically examines association between IT investment and Tehran stock market firm financial performance. This research to study of financial performance, adopts tow types of measurement, namely return on asset (ROA) and return on sales (ROS) and IT capability are classified in three groups as IT infrastructure, human-IT resource and IT-enabled intangibles.In this study, we focus on enterprises which have listed on the Tehran stock market that selected by group sampling method and based industrial group’s bourse firms that selected 79 firms. In the study used by questionnaire and used spss software to data analyze and correlation ship statistics testes.The results suggest that IT investment has positive contribution to IT capability and IT infrastructure have positive contribution to IT-enabled intangibles but human-IT resource didn’t indicate relationship with IT-enabled intangibles. IT infrastructure and IT-enabled intangibles have positive contribution to firm financial performance but human-IT resource didn’t indicate relationship with firm financial performance.

In this paper, relationship between earning persistence and accrual Reliability is studied. At first a comprehensive balance sheet categorization of accruals is presented and then each category according to the reliability of the underlying accruals is classified.The statistical population of this paper includes all the accepted companies in Tehran stock exchange and statistical sample contains 70 companies that have been chosen by stratified random sampling among statistical population, a period from 2002-2008. This paper includes 4 hypotheses. To examine the hypothesis, panel analysis has been used. The results indicate that less reliable categories of accruals lead to lower earning persistence and those investors do not fully anticipate the lower earning persistence, leading to significant security mispricing.

This paper sets out to investigate the link between distributed leadership (DL), self- efficacy and organizational citizenship behaviors. For this purpose, a standard questionnaire was developed based on seven-point Likert scale and its reliability and validity was tested .Then 198 teachers in Tehran was randomly selected and collected data were analyzed using correlation test and regression equation. The findings show that all 2 hypotheses were confirmed and using DL have positive impact on improving the level of self- efficacy and organizational citizenship behaviors.
