Statistical population for this study is two groups of listed companies in Tehran Stock Exchange and also Tehran Stock Exchange investors. 319 investors and also 319 employees of the companies were chosen to be studied out of these two Statistical populations. Structural equation modeling techniques and LISREL software was used to study the correlations between variables. The analysis results obtained suggest that the dimensions of knowledge management have a direct and significant impact on the attitude of investors and attitude of investors also has a direct effect on the behavior of investors.

In the lieu of electronic technology، mobile learning has considered in management studies and education. The diversity and complex competencies of mobile equipment and its infrastructure make it very difficult to generalize the result of research. Hence، in this research we investigate the effectiveness of mobile learning in training and education. We have taken advantage of Kirkpatric training model into first level. The research population was Mehr Alborz virtual university and the sampling method was in order of simple random. The result of quantitative research indicates that there is no significant difference in learning effectiveness in intervention and control group. In the other hand The result of qualitative research indicates that SMS learning has satisfaction for respondents. The findings have a meaningful implication for higher education policy makers in student – professor''s relationship.

The purpose of this paper is to investigate the relationship between human capital (HC) and new product development performance (NPDP) efficiency and in this relationship، organizational learning capability (OLC) is a mediator. Managers، super experts and experts of automobile industry in Iran are elected as statistical society. In this study، results are obtained by path model. Also for better description of results، we use other deducible statistic such as binamial test and one-Sample Kolmogorov-Smirnov Test. The results of this study bode that human capital can improve NPDP efficiency by organizational learning capability. Also the provided model in this research is supported by data.

The goal of present study is review on the relationship and impact of leadership style on purposeful organizational forgetting and organizational performance by using Structural equation modeling. Research method is descriptive and correlation and from the purpose aspect is applied one. The statistical population includes administrators and academic faculty members of Payame Noor University، and the sample size is selected 220 individuals by using the formula and stratified random sampling. Tools include 3 questionnaires consist of the transactional and transformational leadership، purposeful organizational forgetting and organizational performance with optimal validities and reliabilities. Data analyses are done by structural equation modeling and with Lisrel Software and fitness of model is checked by fitness’s indexes. The main results of model with optimum fitness show that leadership styles (transformational and transactional) have direct and significant impact on purposeful organizational forgetting. Leadership styles (transactional and transformative) have direct and positive effect on organizational performance and leadership style has indirect impact on organizational performance by mediating of purposeful organizational forgetting.

The purpose of this paper is to apply entrepreneurial thinking to develop strategies that lead the traditional fisheries activities to innovative and Wealth-generating activities. Therefore، by considering the strengths، weaknesses، opportunities and threats analysis (SWOT)، some strategies for entrepreneurial development in fisheries activities are suggested. To identify strengths and weaknesses، opportunities and threats، relevant documents and interviews have been applied. Finally، after screening the internal and external factors، 5 strengths and 6 weaknesses as internal factors and 5 Opportunities and 6 threats as external factors were identified. Despite the simplicity، SWOT model do not report the importance and priority of the factors. To remove this objection، SWOT analysis has been combined with Analytic Hierarchy Process (AHP) to prioritize the strategic factors، by using comparison matrix. Then، a scale rating mechanism was used to assess the strategic relationship between the SWOT factors and provide the best strategies to develop entrepreneurship in the fishery industry in Boushehr province. The results indicate that the most practical strategy to develop entrepreneurship in fisheries is to assign production subsidies and grants for creative and innovative people.

The Necessity of having an active & diligent management over current organizations & redesigning organization structure is very critical. Contemporary organizations have constantly extended their attempts to design & improve their structures according to fuzzy model. The experience shows that، active sense overwhelming an organization may lead the managers and also the organization to succeed in obtaining designed goals. Accordingly، to estimate contextual dimensions effects on selecting organization structure for a research center associated with aerial industries، a fuzzy multi criteria decision making model is provided. The structures appropriate for the research center are initially considered as the examples، their contextual dimensions also assumed as measuring criteria. The value of each criterion is then estimated using Extent Analysis«and organization structure of under study research centers are prioritized using Fuzzy ELECTRE approach considering their size، environment، control & potency، technology and strategy supply. To confirm the results، decision making model is re-analyzed using Fuzzy Simple Additive weighting models are compared. It is concluded that modular structure is the optimum organization structure for intended research center.
