 Spatial expansion and land use changes in agricultural lands are among important factors contributing to environmental damages and disabilities of productive economy in the region especially in agricultural aspects. This trend is common in developing countries. These changes in land use usually occur by those who target agricultural lands for speculations and other abusing form of economy. In addition this trend also affects environment likewise economy and environment which is attributed as sprawl. Urumia Urban region gains valuable agricultural lands which plays a key role in in both environment and economy. In recent two decades according to excessive construction in the region these areas are turned out to be more of a recreational site for affluent families which has decreased agricultural functions there and also has damaged beautiful landscapes of the villages. Recent occurrence is resulted from not being cost effective agricultural activities and inefficiency of the market supplemented with not supporting agricultural activities. This has leaded that Urumia urban region go through a spatial expansion which differs considerably with urban sprawl. This paper is aimed to analyze effective factors on land se changes and the following sprawl by it. Moreover there are two main questions that should be answered: first is which factors contribute to spatial expansion in agricultural areas? How is attributed the sprawl dominating Urumia urban region? In order to analyze and producing status qua and current relationship between Urumia city and agricultural lands we used a descriptive and analytical method and in order to analyzing development process we went to the documents and finally in order to examine occurred changes we used from satellite photographs and cartographic photos in different periods. After gathering data and statistics and classification in the second stage by observing we tried to perfect the statistics. The results express that the absence cost effectiveness in agricultural activities and speculation in land and of course having nothing in common between users and speculators has resulted a new form of sprawl in Urumia which differs considerably with common forms of it. This new sprawl has features which sustains affluent interests.

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.

The aim of this study was to analyze the impact of social capital and organizational learning on organizational performance in Payame Noor University of Kermanshah province. It is a functional purpose study with descriptive – survey method. The statistical population includes 470 employees of Payame Noor University in Kermanshah province. A sample of 212 people was chosen using Cochran formula. Data were collected through social capital questionnaire of Ownegh (2005), Akbari et al. (2013) and organizational performance of Baharestan et al. (2012). The validity (content, convergent, divergent) and reliability (factor load, composite Reliability coefficient, and Cronbach’s alpha coefficient) of questionnaires indicated that the measurement tools are of good reliability and validity. The results of the research by SMART-PLS software and using t test statistics and path coefficients (β) showed that social capital has strong, direct and significant impact on organizational learning and organizational performance. Also, social capital has strong, direct, indirect and significant impact on the organizational performance. On the other hand, organizational learning can play the mediating role in the relationship between social capitals on organizational performance. On the other hand, social capital can improve the positive effect that organizational learning has on the organizational performance as a moderating variable.

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.

The purpose of this study is pathology of talent management in the automotive industry, so we identify Challenges and barriers, as well as success factors in this filed. This research is a kind of qualitative study that has been done by coding methodology of qualitative data. We used semi-structured interview to collect data. After collecting data and coding, data are divided into two groups of “barriers and challenges” and “success factors” that summarized into definite sets and certain concepts. In studying relations between concepts and categories related to barriers and challenges, 31 concepts were extracted and divided into 4 categories under the titles of structural, environmental, behavioral and managerial challenges and barrier. In studying relations between concepts and categories related to success factors, 20 concepts were extracted and divided into 3 categories under the titles of structural, environmental, and managerial success factors.
