Network data envelopment analysis models and dynamic network data envelopment analysis models cannot evaluated the future performance of the internal structure of decision-making units .In other words, all NDEA and DNDEA models evaluate the past performance of their DMUs and their internal structure, and measure their efficiency and inefficiency, and ultimately rank them based on that assessment .In this paper, we are going to evaluation the future efficiency of deposit and lending sections in bank branches. In order to notified inefficiencies in the internal structure of a unit before the occurrence, we will prevent it.This approach can change the role of managers from the evaluator to the planner .First, using the literature of the subject and opinion of the experts, the structure of the bank branches and the network variables were determined .Then, the values of variables are forecasted using the artificial neural network for the next two periods.Finally, a DNDEA model is formulated using the values of past periods and predicted values.Using its efficiency, its branches and its internal structure have been evaluated in the past, present and future.

In the current study, identification and analysis of the factors affecting the electronic signature effect on the prosperity of the job area between the institutions (case study: oil industry) had been studied.In this study, in order to analyze the resulted data, the descriptive and deductive statistical methods have been used, and the SPSS Software is used in this regard. For choosing the test of the hypotheses, first, the data normality test (Kolmogrov-Smirnov) was used for the calculation. The results of the normality test showed that there is no condition for the equality of the variances and the data are not normal. Therefore, in order to perform the test, the non-parametric tests were used, because the conditions related to the parametric tests were not available. For performing the test of the mean difference between the education and using the digital (electronic) signature, regarding the fact that the education level was in the form of categories, and it was higher than two categories, the one-way variance analysis test was used. To compare the means with each other and to determine the level of the meaningfulness of the differences, Tookie Test was used. Regarding the point that all the persons are inside two categories from the viewpoint of the job backgrounds, the T-Test of the independent groups is used in order to review the job backgrounds of the people. Eventually, the final result of the test of the hypotheses showed that considering all the variables, excluding verifying the identity and being undeniable in the process of job units, the effect of utilizing the electronic signature in juicing up the job in two institutes is too much, and the effect of these two ingredients is lower than the average.

Abstract: Aim: The present study was the effect of professional ethics model of higher education managers on their performance. This research was applied in terms of purpose and descriptive (survey) in terms of data collection. Methods: The statistical population studied in this study included specialists, academic and organizational experts including officials of the central organization, heads and deputies of departments, heads of faculties and group managers and experts and directors of higher education of the Islamic Azad University of Tehran. Based on morgan table and simple random sampling method, 300 of them were selected as the sample size. To collect data, the professional ethics questionnaire of higher education managers and the performance questionnaire were used. Results: The path coefficients, which are interpreted as “standardized regression beta coefficients”, were used to test the research and to determine the effect of the two variables, and the t-value was used to evaluate the significance of the effect. The value of coefficient of significance (t-statistic) for the two research variables is more than 1.96 and the calculated t-test is larger than the critical t-test at the level of error of 1%. Therefore, the professional ethics of managers is effective on their organizational efficiency and its effect is 0.913 and its direction is positive. Conclusion: The results showed that the professional ethics model of higher education managers has a positive and significant effect on improving their efficiency. Therefore, improving the efficiency of employees depends on having a knowledgeable, competent and artistic manager with professional ethics. An efficient and effective manager will be able to improve the level of efficiency of employees by removing obstacles and creating the necessary conditions. Manuscript profile

Establishment of the modern managerial systems is one of the most important steps for the excellence of organizations. The European Foundation of Quality Management (EFQM) is one of the technics that has started from Europe during the two recent decades and nowadays many organizations are in the process of implementing this model with- in their managerial domain. Data Envelopment Analysis (DEA) is a known nonparametric tool for evaluating the organization’s efficiency. In addition to having the capability to measure the total efficiency of a system, network DEA is able to calculate the efficiency of system components. Since EFQM can be considered as a multi-stage system, existence of network DEA along with it can improve the analysis. In this paper, an integrated model has been suggested based on EFQM and Network DEA for assessing the organization’s operation. For this purpose, at first the EFQM has been considered as a ‘four-stage system’ including leadership (the first stage), activities related to employees, policy, strategy and partnership (the second stage), processes (the third stage), and results (the fourth stage). Then considering 32 sub-criteria in EFQM, input and output variables have been determined for each one of the four stage s and on this basis math form for Network DEA model has been developed for this 4-satge system.
