  The measurement of organizational efficiency has always been discussed by various researchers. Data envelopment analysis, taking the inputs and outputs of the decision-making units into account, makes it possible to calculate the relative efficiency for each unit. Many organizations have a two-stage structure, and their performance in successive periods depends on each other. In evaluating such a structure, partial and periodic efficiency must be calculated. Early models and network and dynamic models are not able to calculate this performance alone. Models of existing dynamic networks are also unable to provide a projection for inefficient units or solve all challenges. In this study, by defining the PPS, an input-oriented dynamic two-stage DEA was developed. In this model, the optimal value of the intermediate and carryover variables is determined by the next stage and period, and the stages and periods become efficient backward from the last stage of the last period. In addition to the total structure, the model makes efficient all stages and periods and only becomes an efficient unit if it is efficient in all stages and periods. It was also proved that the projection of the unit to be evaluated is partial, periodic, and total efficient. How to use the model to calculate efficiency was expressed by a practical three periodical example. Manuscript profile

  In the today’s world wherein every routine is based on economic factors, there is no doubt that theoretical sciences are driven by their capabilities and affordances in terms of economy. As a mathematical tool, data envelopment analysis (DEA) is provided to economics, so that one can investigate associated costs, prices and revenues of economic units. Data Envelopment Analysis (DEA) is a linear programming technique used for measuring the relative efficiency of decision making units based on input and output data. One of the applications of this technique is calculation of revenue efficiency. Methods of revenue efficiency calculation in DEA are generally presented for obtaining maximum revenue from output selling, these methods are not sufficiently efficient for evaluation of all system including network systems due to ignoring the internal structure of units and their middle products. Therefore, in this article, in addition to introduction of inverse linear programming in DEA and its application in calculating revenue efficiency, a new method is presented which considers the network structure of units, the ability to determine the optimal price and appropriate costs for efficiency of the unit. The proposed numerical examples demonstrated the superiority of the proposed methods over the traditional data envelopment analyses. Manuscript profile

  Data Envelopment Analysis (DEA) as a non–parametric method is used to measure relative performance of organizational units. The aim of this paper is to develop a new model to evaluate the efficiency of a general two-stage network structures proposed by Li et al. (2012) for measuring the performance of Decision Making Units (DMUs). In addition, this paper expands the work of Li et al. (2012) and improves the heuristic search procedure to estimate the optimal solutions of non-linear centralized models. In order to evaluate the proposed model of this study, it has been applied to a case of regional Research and Development (R&D) system related to 30 provincial level regions in China. The experimental results compared with method developed by Li et al. (2012) show that the proposed method is efficient and has much lower computational complexity. Manuscript profile

  Mutual funds and investment companies are very important institutions for investing in capital markets. Hence, measuring their performance with the aim of identifying efficient investment firms and providing a corrective remedy for inefficient firms is essential. The purpose of the present study is to propose a new approach to assessing the performance and classification of investment firms in terms of uncertainty. Considering the two-stage structure of investment firms, in this research, the approach of network data envelopment analysis (NDEA) is used to evaluate the performance of each stage and the entire investment company. Also, in order to take into account, the uncertainty of the data, the interval network data envelopment analysis (INDEA) model for a two-stage structure is presented. Using the data of 10 active investment companies in Tehran Stock Exchange, the proposed research approach has been implemented and all companies have been evaluated and classified. The results of INDEA model based on non-cooperative approach indicating on the efficacy and effectiveness of the proposed approach of research for performance measurement of investment firms under uncertain data.

  Evaluation of Tehran metro stations based on multiple indices has been studied in this paper. Subway stations have always been considered one of the service centers. Considering that the design and construction of the metro station focuses on the creation of infrastructure, facilities and equipment and then the operational part uses it for the first service, it therefore has two stages of construction and operation. Data envelopment analysis with two-step structure is designed for this topic. The data were collected over five years and attacked four Tehran metro stations. Based on the results of the designed model, the progress and remission of all stations were calculated at each stage and its relationship with financial investment in each metro station was investigated.

  Nowadays, environmental awareness as one of the weaknesses in the management of municipal solid waste is considered. The study was a cross-sectional study was conducted in 1393. For the combined method (method, field, library and documentary, analytical and descriptive) was used. To investigate the contribution of Abadan in the management of solid waste questions in the questionnaire items and Likert five spectral survey of residents in urban areas were used. Accordingly, 383 questionnaires were collected and distributed throughout the city. According to the general theory study of the one-sample T-test was used. In order to evaluate the effect of gender on the participation of T test and impact of education, employment status, income, age structure and status of the contribution of ANOVA test was used. Scheffe's test was used to examine the association between level of education and income levels of participation were used. Thus, the highest participation of citizens in waste management Abadan mean was 3.25 for housewives. The age structure of participation is not effective and the most willing to participate in the Group income (in Toman) of a million to one million five hundred thousand were determined. As a result development and implementation of the operational plan in the field of culturalization and awareness level raising in order to participate more citizens among unemployed, businessman, governments jobs, students and different level income include lower and upper wage between people of Abadan is centralized.

  The problem of the present research is to discover the aspects of literature in the script of Hazardastan as the most famous work of Ali Hatami. Hatami is one of the most influential characters in Iranian cinema whose unique narratives and dialogues in his scripts are unparalleled in the history of Iranian cinema. But it is unique. To the extent that even some of the dialogues and monologues of his works have become proverbs, and clearly the traces of unique dialogues of his works should be searched in the field of Iranian classical literature. In order to solve the problem and achieve its goal, with a descriptive-analytical method, the literature of Hatami's thousand-hand dialogues has been examined from two aspects: firstly, the aspects of the author's use of rhetorical and aesthetic literary techniques have been studied, and on the other hand, using the theory of intertextuality Borrowing aspects of this work from classical literature have been analyzed. The results of the present research show that, first of all, the literature of the dialogue-oriented text of Hazar Dastan is due to the author's benefit from all kinds of verbal and spiritual literary techniques; It is like a metaphor/animation, simile, irony, alliteration, sarcasm and pun. In the next stage, it was found that Hazardastan is connected with the treasure of Iranian literature using explicit and implicit intertextuality. Manuscript profile

  Economic sociology studies the main economic issues of markets, enterprises, industrial centers to production, consumption and distribution. The focus of the new economic sociology is on the role of relationships and institutions and social construction in the economy. Population is considered as one of the important and key factors in the process of economic growth and development of countries. In addition to population growth, the age structure of the population also has important and decisive effects on economic growth by changing the share of the population in the working age. In this paper, the effect of population growth on economic growth with emphasis on the population structure of Iran during the period 1965-2014 has been studied using Markov-switching vector autoregression method. Estimates were made for the three age groups of 0-15 years, 15-64 years and over 64 years in 3 situations (before the war, during the war and the order to increase the population, the period after the war and the order to reduce the population). The results showed that the population group of 0-15 years had no effect on economic growth in any situation, the population group of 15-64 years and above 64 years and population growth on economic growth in position 1 and 3 had a positive effect on economic growth and In situation 2 (period of population growth and due to rising unemployment) have had a negative effect on economic growth. According to the results, the right population policies should be implemented to support and help economic growth and prevent inconsistencies and imbalances in various economic sectors.

  One of the new policies in urban development in general and in the reconstruction of worn and disordered urban structures in particular, is the use of development stimulus projects with the aim of accelerating and facilitating the process of transformation in these structures by using the participation and social power of residents and use. It is a local capacity. This approach has the ability to revitalize existing components in urban centers without the need for large interventions and investments. The stimulus for urban development will not only improve physical conditions, but also economic, social and environmental changes. The purpose of this study is to analyze the role of development stimulus projects in the implementation of urban regeneration policies in the valuable heritage of the 12th district of Tehran, which is examined in four dimensions: physical-spatial, socio-cultural, economic and environmental. . The research method is descriptive-analytical and the statistical population of the study is the residents of District 12. Data were collected by collecting 150 questionnaires and entering the data into SPSS22 software and one-sample t-test, analysis and variance. The results showed that development stimulus projects have a significant relationship with the quality of the surrounding environment and have had a positive impact on economic dimensions, but have not been successful in other dimensions, especially social and physical.

  The structure of epic language in Kushnameh written by Iranshan AbilKhayr *Saman Rahman Zadeh PhD Student, Persian Literature, Urmia University, Iran **Fatemeh Modarresi Persian Literature, Urmia University, Iran ***Bahman Nozhat Associate Professor, Persian Literature, Urmia University, Iran Date of reception: 96/12/11 Date of acceptance: 98/7/17 Abstract One of the subjects in new criticism is to investigate the structure of language in literary works.  The pattern suggested for the study of epic language, studies the characteristic of poetic language used in epic in terms of music, phonetic, diction, syntax, rhetoric, content, and theme to explore how this literary genre manifest itself in language and describes the process of epic composition.  For this reason taking Shahnameh as the yardstick for epic language and employing formalistic theories and the pattern provided by schloars Shahbazi and Malek Sabet in this regard this article seeks to study the epic language in Kushnameh.  At every level necessary parameters are defined their manifestation in the epic language are shown providing evidence to indicate the characteristics of the epic language followed by the enquiry about how successful Iranshan Abilkhayr had been  in using the epic language. Results obtained show that Abilkhayr as one of the imitators of epic language, selecting shahnameh for model had been fairly successful in employing the epic language in many instances and his work is recognized as a complete example of national epic composition after Shahnameh.   * . saman207@gmail.com ** . fatemeh.modarresi@yahoo.com *** . b.nozhat@urmia.ac.ir Manuscript profile
