This paper aims to investigate the effects of job autonomy, psychological empowerment and distributive justice on commitment to productivity of principals in Lorestan state schools. The Statistical population comprises current and former principals. Using random method, 357 out of them were selected. For measuring the research variables, we used 3 different questionnaires. For measuring commitment to productivity, job autonomy, psychological empowerment and distributive justice, a researcher-made, Breaugh (1985), Thomas & Velthouse (1990) and Price & Muller (1986) questionnaires were used, respectively. All of the questions in the questionnaires have 5-point Liker-scale. For analyzing data, covariance-based structural equations modeling-path analysis and AMOS software were applied. The results show that all of job autonomy, psychological empowerment and distributive justice have positive and direct effects on commitment to productivity of principals in Lorestan state. Also, among all of the dependent variables, distributive justice has the highest effect on psychological empowerment. Furthermore, among all the dependent variables, distributive justice has the lowest effect on commitment to productivity.

The continuity of every business depends on rational economic profit, and the amount of economic profit is directly related to efficiency. For management and comparison of similar decision making units (DMUS), relative efficiency is usually used. Tow methods are generally used for efficiency measurement, ratio Analysis and Efficiency Bound Analysis. In the Efficiency Bound Analysis method, at first a boundary is made via the information from the best producers or service providers, so that any activity above this boundary is considered the best performance, and any activity below it is viewed as inefficiency. One of the methods of estimating Efficiency Bound and measuring Relative Efficiency is Linear Programming, which is also called Data Envelopment Analysis (DEA). In this research at first by obtaining the views of the extperts and using pairwise comparisons, the researchers determined the indexes effective on the relative efficiency of toll switched exchanges (Sc/Pcs). Next, the relative efficiency of 39 Sclpc was measured in the constant and variable Return to Scale (CRS, VRS) conditions. Also, additional measurements of DEA and Anderson Piterson (AP), Multi Criteria Decision Making (MCDM) and fuzzy MCDM (FMCDM) were used for ranking Sc/Pcs. The results indicate that in CRS conditions, the average of relative efficiency is 80.23 percent, and that 11 sc/pcs out of 39 Sc/Pcs have 100 percent efficiency. Likewise, in VRS conditions, the average of relative efficiency is 97.77 percent, and 25 Sc/Pcs out of 39 Sc/Pcs have 100% efficiency. An other results of this research indicates that, the moment coefficients of Manpower, Quality of Services and Maintenace have been calculated. The amounts of them are ranked with 0.424, 0.334 and 0.242.

Unemployment is classified as one of the most serious obstacles to economic and social progress. So to avoid the negative effects of unemployment, reducing the rate of unemployment should be considered as one of the leading development goals in developing countries. One characteristic of developing countries is the low rate of productivity growth, and the increase in productivity is the result of reducing the use of resources, reducing costs, using better methods of production or improving the ability of production factors, especially the labor-force. So, the Objective of this research is to study the effect of productivity of labor-force on unemployment in Iran from 1978 to 2010. For the theoretical analysis of the topic, ordinary least squares method was used, and the data were collected by the annual time series coefficients data. The research results of this method indicate that the impact of all variable coefficients has been expected based on the theoretical frame work, the coefficients for all variables are significant, and productivity of labor has a negative effect on unemployment.

Sanctions are coercive contrivances that are applied by a country or a group of countries against another one which transgresses the international laws or contravenes the accepted ethical standards. The aim of sanction is to force the offender to cease its actions or at least to force the country to negotiate for ending its unaccepted actions. This study has been carried out to assess the effects of economic sanctions on the function of internal factors of small and medium size industries of Lorestan Province during 2001-2012. The study was performed in terms of five hypotheses. In order to collect data, the researchers used a questionnaire, the validity and reliability of which were confirmed by related tests. The questionnaire was distributed among the statistical population (managers of the small and medium industries of Lorestan Province), and 127 acceptable questionnaires were received. The data were analyzed by spss software and by using regression method. The results assert the existence of both positive and negative effects of economic sanctions on internal factors. While the sanctions have negatively influenced the performance of production, marketing and finance, they have improved the function of other internal factors such as management and research and development in the sample industries.

In this paper, the impact of mental pressure and its parameters on the performance efficiency of the staff in Islamic Azad University, Tabriz, has been explored. In order to assess the dependent and independent variables of mental pressure, the researchers have used mental pressure questionnaire as well as the labor force efficiency questionnaire. The present research was conducted in the spring of 2012. Regarding the purpose, this study assumed an applied approach to find solution for the existing problems in the organization on the basis of the findings of this research. In addition, this research is considered to be of correlation – descriptive nature. The research population consists of all 776 staff members in Islamic Azad University, Tabriz, from among whom 183 participants were included in the research sample. The study used descriptive statistics for data collection, and parametric and non-parametric analysis for data analysis. The results indicated that mental pressure and its components have a significant impact on the efficiency of labor force in Islamic Azad University, Tabriz.

This research aimed at investigating the function of the educational components in the development of entrepreneurship education programs from the view of the students. The research method was a descriptive-survey with a practical goal. The study population included students of all levels (Ph.D., Masters, and Bachelor). For this study, 220 students of Kharazmi University were selected by using random- stratified method .The research instrument for gathering data was a researcher-made questionnaire, the validity of which was assessed by studying sources and taking views of entrepreneurship education professionals and professors. Its reliability was tested through Cronbachõs alpha test, which was calculated α=0. 93. For data analysis, structural equation modeling approach was used. According to the results, the impact of policies on the development of entrepreneurship education programs has been approved and a direct and positive relation has been verified between the educational components- course performance, ­content of the program, and assessment-and the development of entrepreneurship education programs. Moreover, the findings indicate that the primary fitness indicators verifying the policy and educational factors affecting the development of entrepreneurship education programs confirm the appropriateness of the model.

The Purpose of this study was to identify the factors affecting the quality improvement and productivity of Islamic Azad University centers and branches in Region 2. The study is a survey, and the data were gathered by a researcher – made questionnaire consisting of 50 questions based on the objectives and indices of quality in higher education centers. The statistical population included all faculty members (1778) and non-academic staff (1517) who worked in west Azerbaijan, Zanjan, and Ardebil Provinces during 2012. A sample of 350 (161 faculty members and 189 non-academic staff members) was selected through random stratified multi-stage cluster sampling method and by using Morag's Table. The data were analyzed by mean rank test and Friedman test, and for the comparison of the views of the two groups, t-test and one-way variance analysis were used. The results indicated that among the effective factors, the educational-cultural factors, the management and structural factors, the student factors, and the research factors are ranked in order of importance, respectively. Furthermore, the result showed that there is not a significant difference between the views of the sample groups.

The purpose of the present research is to use a combination of Fuzzy AHP and BSC approaches in order to evaluate the business environment in East Azerbaijan Province. First, the business environment in East Azerbaijan Province was surveyed, and then the results of the studies of the Economic Studies Institute based on Balanced Score Card in four categories-financial , customer , internal processes , and learning and growth-were analyzed.The parameters extracted from the analysis of the business environment and the challenges facing the sector were weighted through the use of fuzzy analysis hierarchy process.Accordingly , the financial area , with a priority weight of 0.126 , was identified as the most important ; the second most important area was learning and growth with a priority weight of 0.068; customer preference, with the weight of 0.057 was ranked third; and the fourth priority was assigned to internal processes , with the weight of o.o47.According to the above priorities , by taking advice from designing experts, 36 strategies were identified to promote the business environment and after further consultation, 14 major strategies were selected, for which guidelines have been presented.
