The purpose of this article is to survey the role of mobile social network in reproduction of the ethnic identity of Kurdish students in Tehran universities. To this end, using the deductive strategy, we have set up a theoretical framework for compilation (the theory of Domestication of Media, Ted Robert gurr's Ethno-Political Identity Theory and Henri Tajfel's social identity Theory). The data collection tool was a written questionnaire. A sample of 400 students from Kurds in social sciences and human sciences of Tarbiat Modarres, Tehran, Shahid Beheshti, Allameh Tabataba'i and Shahed universities were surveyed using cluster sampling. The statistical analysis of the survey also revealed that the social software programs included the Telegram, the Instagram, WhatsApp and Emo. Analytical results have shown that Telegram and Instagram, without controlling the impact of political, social and cultural variables, have been related to the ethnic identity of students, but by controlling the impact of these variables, the impact of the use of social media on telegrams and Instagram has been greatly reduced. Thus, the present paper has shown that modern social media is only a new way of representing the identity of individuals and the main causes of ethnic identity escalation should be sought in the offline world and among structural causes such as relative deprivation, dissatisfaction, ethnical life experience, and so on.

The research aimed to study the effects of social software application on constructivist classroom Characteristics. Applied research and descriptive - survey was conducted. The population consisted of all male and female teachers in the smart high schools that were selected by random sampling, 103 of them were selected as participants. The research's tool is scale of constructivist classes based on e-learning model Mvvdly and scale of social software applications. The reliability and validity of tools was calculated using the Cronbach's alpha and internal consistency. The method for data analysis, average fixed, correlation and regression analysis and structural equation modeling was conducted. The results showed that the use of social software and constructivist classroom Characteristics in the sample studied is higher than average. The use of social software and constructivist classroom Characteristics are taught positive and significant relationship. The results of regression analysis and path analysis showed that the use of the Internet and intranet affect on constructivist classroom Characteristics.

The main purpose of this research is the development of a success model of Knowledge Sharing 2.0 (social knowledge sharing) through organizations. A three-step strategy is used in this research as stated below: In the first step, identification of social software and extraction of factors effective on success of each for knowledge sharing were obtained from literature review. Execution of Delphi method and identification of critical factors were done in the second step. At last, in the third step, a success model was developed based on the obtained results. According to the results obtained from this study, the most important social software in order of their importance for knowledge sharing along with the most significant success factor of each in knowledge sharing are known to be: social network software (the most important critical success factor: active presence of experts and influential individuals in the desired field of knowledge in the social network), weblog software (the most important critical success factor: quality of existing information in the weblog), wiki software (the most important critical success factor: wiki configuration based on key fields of knowledge in organization), podcast software (the most important critical success factor: extent of applicability and practicality of the podcast contents), mashup software (the most important critical success factor: quality of information from mashup sources), tag software (the most important critical success factor: regular and intelligent updating) and RSS software (the most important critical success factor: continuous updating-7×24). Based on the information available for the researchers, originality and innovation of the current work stem from two viewpoints: first, development of the critical success factors of the social software for knowledge sharing and second, development of the success model of Knowledge Sharing 2.0. The proposed model can be used as an appropriate tool for evaluation of success, assessment of status, prediction and related pathologies in connection with establishment of Knowledge Sharing 2.0 in organizations.

In an attempt to enhance knowledge, firms and corporations have been overwhelmed with assorted methods for retaining employee wisdom. To pay attention to the benefits of a successful knowledge management program can help create competitive advantage. Therefore, numerous knowledge management solutions have been developed and implemented. Some of these knowledge management initiatives provide a means to accumulate, organize, and access the firm’s most essential asset. With the advent and spread of information and communication technologies, especially Internet, social software and communication tools has risen to the challenge of capturing knowledge with a variety of methods. One of these tools is wiki that provides a new way of collaboration and knowledge sharing. Wiki is a software that allows users to work collectively on a web-based knowledge base. This paper reviews the role of wikis in knowledge creation and management
