The pervasive growth of ICT has had a huge impact on the banking industry. Providing banking services to customers via mobile phone is one of the newest technologies. Accordingly, in this study, the intention is to investigate the effect of perceived convenience, usefulness and risk, trust and social effects on the intention to use mobile banking in the customers of Bank Melli Mobarakeh. The statistical population of customers of Bank Melli is Mobarakeh. Sample size was selected using Morgan table of 381 people based on available sampling method. A standard questionnaire was used to measure the variables. The validity of the questionnaire was evaluated diagnostically, convergently and divergently and the reliability of the questionnaire was assessed using Cronbach's alpha coefficient. The research model was tested based on structural equation method and pls software. The results showed that perceived convenience, usefulness and risk, trust and social effects had a positive and significant effect on the intention to use mobile banking.

As policy interventions in financing higher education system in Iran lacks the adequate effectiveness and efficiency, it is necessary to redefine the role of government and other actors in higher education industry. In this study, based on the individual utility and social utility of disciplines, an expert model was developed to determine the appropriate financing mechanism for humanities in bachelor degree. Using the experts’ knowledge along with the literature and fuzzy inference system, an expert model was designed by MATLAB software 2020a. Priority of the field in the “comprehensive scientific map of Iran” and indicators of social and individual utility of disciplines (extracted by research team) were used as inputs of model. A software was developed which presents the final model to determine mechanism of financing disciplines. Study of two sample disciplines resulted in “Market” group mechanisms for Law and “Government” mechanisms for Persian Language and Literature. The results show that simultaneous attention to individual and social utility of disciplines can improve prioritization and policy-making in financing. It can also increase the productivity of investment in higher education. Therefore, using this approach, it is possible to redefine the role of government and regulate the relations between actors in the higher education industry in order to increase the efficiency and effectiveness of government investment in higher education, implement Development Programs, keep a balance in higher education market, extend market-oriented disciplines, avoid mass production of graduates, and prevent the excessive development of universities and higher education institutes.

Because of the importance of observing disciplinary rules as one of the serious demands of commanders, recently, there has been an emphasis on the need to develop a well-defined mechanism for assessing disciplinary principles in the Naja. On the other hand, the effectiveness of implementing disciplinary codes, like any other objective measure, needs to be grounded and made appropriate by changing attitudes. Research aims to test police officers' attitude to discipline in the armed forces. In order to design a questionnaire for measuring employees' attitude to discipline codes, based on the existing literature, the primary tool was designed and for content validity, the Relative Content Validity Ratio (CVR) was calculated 0.98 with 10 experts. The reliability of the instrument was confirmed by Cronbach's alpha of 0.97. The statistical population of the study consisted of the staff of the five command staffs of the NAJA mission.Then the data were analyzed by t-test and Friedman tests using SPSS software. The research showed that police officers' attitude toward disciplinary codes was positive and moderate. Among the attitude dimensions, emotional, behavioral and cognitive attitudes are in good order, respectively. This result shows that the behavioral orientation of employees to comply with the Code is more emotional than cognitive, which confirms the need for investment to improve the employees' understanding of the usefulness of the Disciplinary Code.

Given the variety of factors influencing on financial decision making and subjective nature of the most decisions is only part of their features associated with Multi-Criteria Decision Making. The aim of study is the rating of companies at TSE based on fundamental analysis and the appraisal of investor’s utility during the period of 1390 to 1396 years. So first, after determining the weights of indicators used based on the opinion the experts and using the ARAS method, the companies have been ranked and then their utility basis on stochastic dominance method have been investigated. The findings of research show that the first-order stochastic dominance cannot be identified. However the result ofThe Davidson test for the stochastic dominance of the second and third order indicate that the high-rating stocks has dominance to low-rating stocks.

TOPSIS is located in compensatory decision-making methods. The basic principle is that the chosen alternative should have the shortest distance from the positive ideal solution and the longest distance from the negative ideal solution. The existence of incremental and decreasing uniform trend in positive and negative criteria is one of the TOPSIS characteristics in determining positive and negative ideal points. While the utility assigned to the decision maker after a certain level in each criterion will be less tangible. Therefore, in the ranking of alternatives in addition to the value of each alternative in each indicator, the balance among criteria of each alternative should be considered so the alternative that has an appropriate place in an important indicator, but does not have an appropriate place in other criteria, not to be the first chance for selecting. For this purpose, in this paper by adding virtual dimension to the decision matrix that comes from the deviations among criteria of each alternative, we have tried to compensate the mentioned weakness. To evaluate the proposed method, three different examples are presented. Thus, each of the three provided examples, solved by proposed method, TOPSIS, VIKOR, Deng and SAW and then by using the Spearman correlation coefficient the number of significant correlation relationships between the proposed method and TOPSIS with the other three methods were compared. Then, the rating similarity percentage of the proposed method and TOPSIS were compared with VIKOR, Deng and SAW.
