Despite the development of appropriate academic and experiential background knowledge management and its manifestation as a competitive advantage، many organizations have failed in its effective utilization. Among the reasons for this failure are some deficiencies in terms of methodology in inappropriate recognition and translation of KM dimensions and lack of systematic approach in establishment of causal relationships among KM factors. This article attempts to design an Organizational Knowledge Management Excellence Model. To design an organizational knowledge management excellence model based on library researches، interviews with experts and interpretive-structural modeling (ISM) was used in order to identify and determine the relationships between the factors of km excellence. Accordingly، 9 key criteria of KM Excellence as well as 29 sub-criteria were extracted and the relationships and sequence of factors were defined and developed in 5 levels for designing an organizational KM excellence Model. Finally، the concepts were applied in Defense Organizations to illustrate the proposed methodology.

Development of the E-Commerce in manufacturing companies and planning in this area requires knowledge on the factors affecting the decisions made by manufacturing companies to use e-commerce tools. These factors can be divided into two categories: internal and external. The internal factors show the characteristics of domestic firms that will shape their behavior، while the external factors represent the business environment of firms and include e-commerce infrastructure and supportive agents، governmental، legal and cultural factors and social factors. In this paper، the role of internal and external factors in the use of e-commerce tools in textile and clothing enterprises of Isfahan was discussed using factor analysis technique and correlation coefficients. Field survey results indicate that internal factors (prospective and strategic management، business size، flexibility، performance and expected performance) have the greatest impact on the use of e- commerce tools. Afterwards، the appropriate supporting factors (availability of skilled work force and ease of use) and favorable social and cultural factors make greater use of e-commerce tools possible for textile and clothing companies in Isfahan.

In recent years،Internet-based banking services have become the focus of competition in Iran’s banking system. In this respect، Internet banking users’ identification and segmentation leads to better understanding of users’ needs and expectations and planning to meet them. This in turn will result in improving the image of the bank and obtaining competitive advantage. In this research، seven banks of Pasargad، Mellat، Parsian، Saman، Eghtesad-e-novin، Tejarat and Melli are selected as rival brands. According to scrutiny، the expectations of internet banking users were identified in the form of 17 indicators. Using closed questionnaires، necessary data was collected from 274 users of Internet banking services in selected banks. At the first stage، based on exploratory factor analysis، five factors were identified which include: ease of use، variety of e-banking services، security، speed of providing services and reliability. In the second stage، by applying k-means procedure، optimum number of clusters was detected equal to 6. Then the expectations of each cluster were evaluated. The result showed that the average of expectations and frequency of demographic variables between clusters are different. So the extracted clusters have good quality.

In recent years، virtual communities have been significantly popular and almost all of them are targeted for business profitability. In our study، the profitability of these communities for businesses has been analyzed from a commercial perspective. The study considers virtual community as a business model which can have a great impact on consumer purchase decision process. With respect to reference groups and word-of-mouth recommendations in virtual communities، contributing factors have been detected and a model of impacts and relationships between these factors has been presented. Hypotheses of the mentioned model are evaluated by making use of a questionnaire completed by 110 members of virtual communities. Using AMOS program and path analysis method، statistical analysis of received responses showed that factors such as virtual community''s information quality، trust between people، sense of belonging، virtual community members’ perceived benefit and members’ permeability are effective to different degrees، and there is no significant relationship between social identity of members and their permeability.

Nowadays، a movement has begun toward offering services by means of portals to realize the goal of making the electronic city، and Iranian municipalities have already entered this scope. This investigation aims at measuring the realization of above-mentioned goal by investigating into municipality portals، since the typical view of an e-city and the user interface between management processes of an e-city and citizens is a portal that all city services will be available through. A multi Case study using structured observation is the method used for the current investigation. Municipality portal services of five most populated cities in Iran including Tehran، Mashhad، Isfahan، Shiraz and Ahvaz were investigated، and then they were compared with municipality portal services of four none-Iranian municipality portals. According to the results of the present research، less than 50 percent and 60 percent of the world e-city services were found to be offered in Iranian municipality and none-Iranian municipality portals، respectively. The results obtained from the current investigation would have some suggestions for improvement of Iranian municipality portals.

Today، online social networks are very popular due to the possibility of creating relationships between people all over the world. These social networks with possibilities such as friend recommendation generally use local features derived from social graph structure. For friend recommendation، there are different algorithms with local and global approaches. In this paper، we proposed an algorithm with local approach that has a suitable performance compared to other algorithms. In addition، it has an acceptable speed، because of its being local. This new feature was examined on two large social networks: Epinions and Facebook. The research showed that this algorithm can present good predictions and acceptable recommendations.
