- چکیده:
- چکیده انگلیسی: Nowadays, there is a growing trend in the constitution of community of practice (COP) through cell phone communication software. So, studies about COP and its functions seem necessary. In this research, the positive functions of COP have been identified through theme analysis, and then the identified functions have been categorized using exploratory factor analysis. This research has been done in two phases using mixed-method approach. In the qualitative phase, library resources and in the quantitative phase, researcher-made questionnaire were used. In addition, in the qualitative phase, the functions were identified through literature review. The statistical population of the quantitative phase includes employees of public organizations and private firms who are a member of any groups, consisting of their colleagues, on their cell phones using social communication software such as: Telegram, WhatsApp, and Viber. Purposive sampling was used to select the groups and the individuals. 446 individuals, within 19 groups, filled out the questionnaire. 38 main themes have been identified and divided into 6 categories of innovation and problem solving, information and knowledge exchange, collective identity, knowledge ability, continual development, gain and create value.

- چکیده:
- چکیده انگلیسی: The Fe3O4 nanoparticles and the supported ionic liquid (Fe3O4-IL) were produced and used as efficient magnetic catalysts to synthesize the benzimidazole derivatives under solvent and solvent-free conditions. Quantitative conversion of the reactants was achieved under solvent-free conditions; catalyst reusability, through convenient magnetic decantation, showing an insignificant loss in activity. The catalyst can be readily isolated by using an external magnet and no obvious loss of activity was observed when the catalyst was reused in seven consecutive runs.
