Nowadays, one of the topics of interest to researchers is the authority of teachers, and fades it in universities. Look at the reality in the society and comparing with historical context motivates researchers to question why some of the professors at the university have less authority. For this purpose, this research is trying to focus on economic and demographic factors, to answer questions. The method used in this research is descriptive analysis using survey techniques and data collection tool is a questionnaire. The population consisted of professors of Kermanshah PNU in the academic year 2011-2012, total number of them is equal to 258. Due to the large size of the population, using the Lin sampling table sample size is 258, which for the study based on striated random sampling were selected. In the present study, face validity assessment method and construct validity based on factor analysis were used. To determine the reliability of the statements of each variable, Cronbach's alpha used. Results using SPSS21 and Amos21 statistical software were analyzed. Mean traditional authority equal to 13.57, then charisma authority13.54, and intellectual authority is 18.72. The dimensions compared with the average expected for above dimension respectively traditional authority 15, charisma authority 12, intellectual authority is 15. The results show that there is a significant relationship between relative deprivation and professor’s authority (r=-0.301), the use of mass media and professor’s authority (r=0.161), monthly income and professor’s authority (r=-0.153). In addition, the results of comparison show that average of the professor’s authority among the courses is different, and this difference based on f test is significant. The average professor’s authority, for people with different degrees is different. The results of Multiple regression indicate that the traditional authority (T=4.335), self-esteem (T =3.925), charismatic authority (T =3.788), and the relative deprivation (T =-2.287), total 0.42 from internal changes explain the value of professor’s authority variables. Furthermore, the results of structural equation shows that Chi square insignificant CMIN is equal to 211.143, square root index mean residual square or RMSEA is equal to 0.075, RMR index or residuals mean square root is equal to 0.098, the Chi-square to the degrees of freedom ratio CMIN.dF in model is 3.199, against the CFI comparative fit index 0.926, and comparative fit index thrifty PCFI, are equal to 0.671 Comparative and thrifty indicators for evaluating the overall model calculated that show collected data to support the theoretical model considered.

To empower the farmer villagers, execution of training programs including semi-presence training, open training and virtual training is essential. The main purpose of the present research is to determine the factors affecting the enabler trainings to farmer villagers with an emphasis on the component of culture and education technology using the interpretative structural modeling together with structural equation modeling. The combined method has been used as the research method. At the first stage, the main indices were extracted by data collection via Delphi method from the knowledge transfer and management and their validity were determined, and at the qualitative stage the questionnaire was given to the participants after determining the reliability. The statistical population consists of 1930 individuals including faculty members, promoters, educational instructors and those employed in agriculture research centers and institutes. With regard to Morgan table, the sample size has been estimated to 641 individuals by separation of groups per their population and the samples have been selected using the stratified random sampling method. The research question was examined and standardized using factor analysis and Cronbach's alpha. Research findings elaborate the component of remote education technology and organizational culture as the dimensions of management and electronic knowledge transfer. It is suggested to the managers at agriculture information and knowledge system to take action to expand the agriculture service centers and equip them with information and communication technology facilities for fast transfer of research findings to farmers and culturalization in sharing the research findings.

Value stream mapping because of being able to understand process bottlenecks, as one of the most common tools for analyzing, identifying and eliminating various losses in operational and support processes are used. On the other hand, inventory management, precise control entry and exit of goods, accurate and timely information about the inventories status and planning, reduce product maintenance costs, including important issues organizations have a special look to it to consider the whole objectives and strategies, making procedures and policies that have a positive effect on the overall organization’s economy. In this paper, the use of value stream mapping as a lean production technique, in a production process to improve inventory control is discussed. This is a tool seeks to reduce losses, especially losses related to inventory by mining a bearing manufacturer companies. In this study, the literature of value stream mapping considered. The current state and future state of the company drawn in order to improve production process and losses in the company's future status. In addition, after drawing the mapping, the results of the simulation software Arena and the final report suggests that the use of this technique has an impact on reduce losses and increase inventory turnover.

This paper aims at studying governance and distribution of autonomies in Tehran City Islamic Council in the process of performing intra/inter-organizational functions. According to current theories on governance, there are three types of governance according to the kinde of involvement. Authority involvement, interactive involvement and persuasion involvement, in Tehran City Islamic Council in the process of forming and implementing urban regulations. On the other hand, Tehran City Islamic Council could have three kinds of autonomies to be effective: autogeny, heterogeny and discretion. Good governance model for Tehran City Islamic Council is an optimized combination of involvements and autonomies designed by polling the elites a mathematical model analysis. To study the current governance status in Tehran City Islamic Council, a questionnaire is used and the interval is estimated by single T-test. The findings indicate that in terms of involvement and autonomy, Tehran City Islamic Council has a remarkable distance from optimized governance model.

The aim of the present research was to study the impact of organizational culture on entrepreneurial orientation given the mediating role of knowledge management. The statistical population consisted of the employees of district 1 and 2 municipalities of Qazvin who were about 200 in number, of whom 130 people were selected based on stratified random sampling method and Cochran formula. Data analysis was done using structural equation modeling with the help of LISREL 8.8 software and Smart PLS 2 in two parts: measurement model and structural part. In the former, technical characteristics of questionnaire were evaluated and the necessary amendments were made; and in the second part, the coefficients of structural model were used to test the hypothesis of the research. The results indicate a significant and positive impact on the entrepreneurial orientation of organizational culture and knowledge management on the one hand and on the other hand a significant impact on the relationship between the two of the mediator of knowledge management.

A sensitivity analysis of the flood safety of Solaimantangeh dam using a regional climate change simulation is presented. Based on the output of the CCSM (Community Climate Change System Model) general circulation model, the NIRCM (North of Iran Regional Climate Model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. Using the SRES (Special Report Emission Scenario) “B1” Climate Change Scenario when applied to the Tajan river basin, where Solaimantangeh dam is located, NIRCM reduces significantly the bias in Annual Maximum Event total Precipitation (AMEP) & Annual Maximum Daily Precipitation (AMDP) that CCSM shows. The stream flow change scenario is then simulated using SSARR (Stream flow Synthesis and Reservoir Regulation) model. A rainfall-runoff model was implemented using precipitation and temperature projected by CCSM and NIRCM. The model demonstrated that average Stream flow would increases 38.7% and the variability would increases 14.3%. This remarkable increase in projected annual maximum flow for the next 20 years (2004-2023) should be a significant negative signal to water resources managers. The results indicate that the number of floods remains almost the same, but that the magnitude of a single flood event and the recovery from it become worse.

Typology solution in architecture science seeks classifying constructions and spaces in terms of join features. Typology studies can be infrastructure of design in micro and minor levels. Therefore being oblivious of it in architecture and city planning can lead to state of chaos in urban aspect and makes heterogeneous urban textures. Current paper seeks to find factors influencing on formation of different housing types in old texture of Gorgan and to generalize them in contemporary designs. By influencing in all ratios from residential areas to alley and neighborhood it can make a texture to solve problems such as density and transportation. The research method is descriptive-analytical. Information were obtained and analyzed by a combination of documentation studies and deep interview with experts` views where some questions were asked in old texture of Gorgan. The research findings indicated that economy factor has an effective role in type of design of old residential texture of Gorgan along with two factors of climate and culture. Economic factor has had abundant influence in size of houses, their communication and climate left influence in formation of appearance of buildings and their yards and finally culture left effect on religious factors, social relations, security and so on) finally the results indicate old texture of Gorgan apply certain and systematic principles in design in which all sporadic sections look like a uniform.
