Knowledge management plays an essential role on developing efficient systems in educational systems. However, there are different factors influencing the success of knowledge management. In this paper, we present an empirical study to measure the impact of six cultural based factors including management support, organizational affiliation, employee participation in decision-making, staff welfare organization and establishment, adaptation of new policies and organizational and internal organizational climate on establishment of knowledge management. The proposed study of this paper is implemented in 114 selected educational organizations in city of Tehran, Iran. A questionnaire is designed in Likert scale, it is distributed among experts, and using regressions analysis and structural equation modeling, we have analyzed the data. The results of regression analysis indicate that management support, staff welfare organization and internal organizational climate are among the most important factors while other component did not represent any significance on knowledge management implementation.

Cultural variety is a behavioral characteristic of investors and evaluating the cultural influences in the area of financial management on the decisions of investors plays an important role.

In this paper, a questionnaire was designed including 22 cultural items in three criteria of values, facilities and behavior in order to measure the cultural factors affecting investment in stock exchange. Experts’ comments were used on the design of items and quintet Likert spectrum was applied for the answers. Structural equation modeling, or multivariable analysis with latent variables, is a comprehensive statistical approach for testing the hypotheses about relationships between observed and latent variables. Such analyzes have been done by LISREL software and the results showed that there was a significant relationship between investment and its triple factors and also between the items and triple factors affecting on investment.
