Aim: Scientific recommender systems have been developed to provide users with resources that are close to their information needs. The main objective of the present study was to compare the effectiveness of the related articles recommender systems in Google Scholar and Web of Science databases from the users’ perspectives.Methods: This is an applied research with comparative approach. The samples included both human and paper ones. The human samples consisted of 120 Ph.D. candidates at Shiraz University. From among each field, thirty students (i.e., totally 120 students) participated in the study. The paper samples consisted of 2,400 related papers, 1200 of which were retrieved from Google Scholar, and 1,200 of which were retrieved from Web of Science database. The data were collected by a questionnaire and software.Results: The results showed that users considered both Google Scholar and Web of Science databases as effective in retrieving the related articles. There were significant differences between each of the four areas of humanities, basic sciences, engineering, agriculture and veterinary science in terms of the effectiveness of the related articles function. In addition, both databases represented the least number of related articles and the largest number of unrelated articles in the area of humanities. Originality: Despite the importance of related articles recommender systems, there was no evidence that measures the effectiveness of related articles recommender systems in Web of Science and Google Scholar.

Purpose: The purpose is to review various views about the composed research method, and to obtain a relatively comprehensive cognitive knowledge. Method: This is a conceptual paper in which, using related literature and concepts of chemistry, the intention of composing the two quantitative and qualitative research methods is identified so that it leads to a better understanding of the composed research method. Results: Findings show that different researchers of the composed method disagree with each other over the kind of mixing the two quantitative and qualitative research methods. Some scholars find it blended into data, methods, and findings, on the contrary, some consider a composition of theoretical and philosophical foundations and some other know a mixture by combining each of these items. Mixing the two substances together is one of the basic subjects of chemistry. In chemical science, when mixing the two substances changes the physical nature of the material, it is mixed up, but if, in addition to change their physical nature, the chemical structure of the material is changed, and a new material is produced with a new chemical structure (the new chemical nature), it is called a composition. Accordingly, a change in the type of data, methods, and findings can be regarded as a change in the physical nature in chemistry and a change in the theoretical and philosophical foundations can be considered as a change in the chemical nature in chemistry. using the dialectical approach as a composed approach in the information retrieval studies is suggested.

Purpose: This study intends to explore the personal knowledge management (PKM) skills and capabilities of staff of Shahid Chamran University of Ahvaz (PKM) based on Avery et al model (2001) in order to provide strategies for improving individual and organizational knowledge management performance in this university.

Aim: The aim of the research is investigating Interaction category in information seeking process based on Radical Change Theory by studying the communications of newcomer bachelor students in Cyberspace.Methodology: The general approach of the research is Qualitative and the method is Grounded Theory. The population of the research was newcomer bachelor-degree-students of the faculty of Education and Psychology (University of Tabriz). The sampling method was snowball. Finally, the data was matured by points of 21 students. The data analyzed by MaxQDA.Findings: After three levels of open, axial and selective coding, 9 conceptual categories, was identified. The identified conceptual categories were: the time of daily usage of virtual space, the motivation and aim of usage of virtual space, information search strategy, the impact of virtual space on internal emotion of people during usage and during information finding process, impact of environment on the way of information obtaining, the impact of personal characteristics on the way of information obtaining, interesting and attractive characteristics functions Internet, and the way of storing and usage of information resources.Result: One level of the complicated process of Information seeking is interaction which user during information stage and encountering with the system is demonstrated. The result of the research showed that that the main effective factors of the level are the environment and internal emotions of the user.

Purpose: The aim of the present research is to study the effects of the digitalization of the system on the organizational effectiveness of academic libraries based on Parsons' theoretical model of the four functions of social systems. Methodology: The research population consisted of 12 academic libraries in Tehran, which were studied in three levels of high, average and low based on the degree of digitalization. This analytical-practical research employs the survey research method and uses a researcher-created checklist and a standard questionnaire to collect data. Excel, SPSS16, and Smart PLS software were used to describe and analyze data. Findings:The results of the study support its general conceptual framework and its assumptions. The findings show that in general, there is a significant positive correlation between the digitalization of academic libraries and factors determining organizational effectiveness. Digitalization of the system has the highest impact on innovation, organizational health or morale, organizational commitment and the job satisfaction of librarians in order of priority. In terms of the level of digitalization, 50% of academic libraries were at" level average", 33% were at "level high" and 17% were at "level low. The highest digitalization score earned by academic libraries was 65.21% and the lowest score was 22.22%. F-test results show that statistically, there is a significant difference between «level average» and «level low» libraries in terms of the librarians' innovation and organizational commitment. The average organizational commitment and innovation is higher in "level low" libraries than "level average" libraries.
