The purpose of this study was to determine the digital gap between generations in terms of the familiarity, interest, and usage of information and communication technology. Research method was analytical survey and a questionnaire was used as a data collection tool. With regard to the broad research population, non-random purposive sampling of boys and parents, including 102 male students of third year secondary schools and first year high schools of region 10 in Tehran and their parents (102 father or mother) were selected and in terms of familiarity, interest, and usage of technologies such as Internet, email, chat, computer games, and mobile phone were studied. The results of research showed that the average amount of familiarity, interest, and usage of technologies in parents was 2/04 and 3/16 for children. The gap between parents and children, in terms of familiarity with IT was -1/22 while -1/24 in terms of interest and -0/88 in terms of usage of IT. The research hypotheses tests showed that there were significant differences between the average familiarity, interest, and usage of information technology among children and parents.

The present paper discussed results of a study which aimed to explore the knowledge and use of Web 2.0 technologies by LIS academics in Iran and to explore the challenges they faced for using these technologies. The research method was explorative and empirical. Data was collected through a web-based survey questionnaire containing both open and close ended questions. The results showed that LIS academics in Iran had good level of familiarity with some Web 2.0 tools such as blog, wiki, YouTube and Facebook. However, their familiarity with some other Web 2.0 tools such as RSS, feeds, Twitter, Flickr, Delicious and podcast was limited. Blog, discussion groups, chat tools, file sharing tools, Wikis, SMS, video sharing tools and forum were used respectively by LIS academics in their teaching. Internet filtering was identified as the most inhibiting barrier to the use of Web 2.0 tools. Lack of access to high speed internet and lack of training were pointed as the other identified barriers. Authors suggested that to reap the benefits of Web 2.0, LIS academics needed to find alternative non filtered Web 2.0 tools to employ in their teaching and research.

The present study endeavored to analysis the scientific publications that were indexed in the Web of Science database as the information management records and the visualization of science structure in this field during 1988-2009. The research method was scientometrics. During the study period, 1120 records in the field of information management have been published. These records were extracted in the form of plain text files and stored in a PC. Then they were analyzed by ISI.exe and HistCite softwares. Author's coefficient collaboration (CC) was grown from zero in 1988 to 0.33 in 2009. Average coefficient collaboration between the authors was 0.22 which confirmed low authors collaboration in this area. The records have been published in 63 languages. Among these records the English language with 93.8 % possessed the highest proportion. City University London and the University of Sheffield in England had the most common publications in information management field. Based on the number of published records, T.D. Wilson with 13 records and 13 citations ranked as the first. The average number of global citations to 112 documents has been equal to 8.78. Despite the participation of different countries in the production of documents, more than 28.9% of records have been produced in the United States. According to results, 10 countries have published more than 72.4 percent of the records. City University London and the University of Sheffield have had highest frequency in this area. 15 journals have published 564 records (50.4%) of the total productions. Finally, by implementation of scientific software HistCite map drawing clustered and authors, articles and four effective specific subjects were introduced.

There are many national and international ranking systems rank the universities and higher education institutions of the world, nationally or internationally, based on the same or different criteria. The question is whether we need all these ranking systems? Are the outcomes of these ranking systems as different as they claim? This study collected data from the results of seven major ranking systems including Shanghai, QS, 4International, Webometrics, HEEACT, and Leiden University ranking and analyzed them. Results showed a significant correlation among the outcomes of these international ranking systems in ranking and rating the world's top 50 universities. The highest correlation was between Shanghai - THE (Spearman's Rho = 0.85); Shanghai - Webometrics (Spearman's Rho = 0.81) and Shanghai - Leiden (Spearman's Rho = 0.80). Finally, some suggestions for improving current ranking systems have been investigated.

Due to different effects of ICT on varied aspects of performing the duties in organizations, governments have been intending to use ICT in the recent years very dramatically. The significant issue to which we should pay attention is the using of ICT without directing attention towards the mutual effects of different ICT domains shall be resulted in malfunction and inefficiency of organizations in carrying out their tasks. Therefore, the present research tried to develop a systematic structure in ICT domain and analyze the various ICT domains in order to identify the penetrating and penetrated factors (cause and effect). In doing so, at the present research firstly by the usage of other researcher's results and achievements, it was attempted to specify the different ICT domains including objectives, obstacles, drivers, team dynamics and organizational support and then another elements so-called ICT effectiveness was added in order to study the effect of above-mentioned factors on ICT effectiveness. Then, standard fuzzy DEMATEL technique questionnaire was distributed among 35 persons of experts working in ICT and IT fields to gather required information and data. After gathering required data and information, they were analyzed through DEMATEL techniques in fuzzy states, respectively. The results obtained from the DEMATEL technique in fuzzy state reveal that in ICT domain, the objectives were determined as the most penetrating elements into other elements of ICT domain and the drivers were the most penetrable element in ICT domain too.

One of the key aspects of knowledge management is organizational culture. Finding an appropriate culture and key indicators for culture in implementation and execution of knowledge management are one the most important matter in knowledge management implementation in any organization. So, the main purpose of this article was presenting a multidimensional structure for organizational culture and supply chain culture with the aim of effective knowledge sharing in supply chain of automotive industry of Iran. First, according to the literature review, key indicators for any dimension of multidimensional structure of the research were defined. Then, key indicators were revised, adjusted and modified by three industry experts and three college professors, so 4 questions and 5 hypotheses were offered. Next, that multidimensional structure has been assessed as a survey and cause-effect study in supply chains of Iran Khodro Company and Saipa Company.115 industry professionals have participated in this study. In the research, after testing co-linearity between variables, relations between different dimensions of the multidimensional structure have been assessed with the help of path analysis. Research findings showed that the multidimensional structure introduced in the study had an appropriate fitness in automotive industry. The results of path analysis also showed that the culture of the supply chain has had the greatest impact of Business culture. On the other hand, business culture had a strong but indirect effect on supply chain performance. And finally, the greatest effect of knowledge sharing and transferring was on non-financial performance of supply chain.

The main aim of this research was to answer this question whether the course reading lists in online syllabuses can be used as a valuable source for research evaluation. The Research population included 8043 citations from 350 online syllabuses from departments of library and information science in the United State during 2000-2009.The results of correlation tests showed that there were significant and direct relationships between Scopus, ISI (WOS), Google Scholar and Google Book citations at article journals and books levels. The results indicated that the methodology applied in this study can be used as a new and applied approach to access the impact of research on education.

Knowledge is identified as a critical factor for innovation. On the other side, knowledge creation takes place through investing on R&D activities and developing new products. Furthermore, not all types of R&D activities result in similar types of innovation. Indeed, investing on research activities result in radical innovation and investing on development activities concludein incremental innovation. Keeping a balance between these two kinds of innovation in products is critical to acquire competitive advantages. To investigate the dynamic-nature and complex relationship between knowledge creation and investing on R&D activities, presenting paper tried to study impacts of different investing policies on knowledge stockusing a systematic view. Hence, “system dynamics” which is an approach to study the complex system is used to model and simulate the presenting system. Beside, a case study was also presented to test applicable capability of the model. The simulation results showed that investing policies on R&D activities must be based on comparing the real performance and the goal performance.

In spite of increasing interests and trends among Iranian organizations to incorporate information and communication technology (ICT) into service provision to their customers, there is still considerable gap between existing and expected diffusion. The aim of this study was to identify and evaluate main determinants of technology adoption and use on the basis of modified TAM model. The developed model was validated through survey research and data collected from a randomly selected sample of 263 students at Ferdowsi University of Mashhad. Data analysis was conducted using appropriate statistical techniques including regression, and Chaves analysis. The findings of research confirmed the validity of principle model, confirming ease of use and perceived usefulness as main determinants of technology acceptance as suggested by Davis. This study also suggested that the quality of system and personal ability to use technology were good predictors of ease of use, while social interaction and images appeared to be good predictors of perceived usefulness of technology. Furthermore, personal innovativeness proved to have significant effect on intention to use among potential ICT users.

When the World Wide Web provides suitable methods for producing and publishing information to scientists, the Web has become a mediator to publishing information. This environment has been formed billions of web pages that each of them has a special title, special content, special address and special purpose. Search engines provide a variety of facilities limit search results to raise the possibility of relevance in the retrieval results. One of these facilities is the limitation of the keywords and search terms to the title or URL. It can increase the possibility of results relevance significantly. Search engines claim what are limited to title and URL is most relevant. This research tried to compare the results relevant between results limited in title and URL in agricultural and Humanities areas from their users sights also it notice to Comparison of the presence of keywords in the title and URL between two areas and the relationship between search query numbers and matching keywords in title and their URLs. For this purpose, the number of 30 students in each area whom were in MA process and in doing their thesis was chosen. There was a significant relevant of the results that they limited their information needs to title and URL. There was significantly relevance in URL results in agricultural area, but there was not any significant difference between title and URL results in the humanities. For comparing the number of keywords in title and URL in two areas, 30 keywords in each area were chosen. There was not any significantly difference between the number of keywords in the title and URL of websites in two areas. To show relationship between number of search keyword and the matching of title and URL 45 keywords in each area were chosen. They were divided to three parts (one keyword, two keywords and three keywords). It was determined that if search keyword was less, the amount of matching between title and URL was more and if the matching between title and URL was more, the rate of relevance of website was more. The research concluded that if users with specific names limit their search in the URL, they can get more related results. Also they can get better results by controlling of their search keywords. Specific search engines can also increase the weighting of keywords in the URLs and rank more relevant results to their users.

This research aimed to investigate Iranian papers on nanotechnology area against some scientometrics indicators such as most prolific, most cited and so on. The statistical population were all papers have been published by Iranian researchers on nanotechnology in the Science Citation Index (SCI) from 1991 to 7 August 2011 (4605 records) that has been done with the aim of identifying, the most prolific, most cited and most effect of Iranian nanotechnology scientists. The results showed that the collaborative index in per-document was 3.39. The highest collaborative index was in 1997 with six authors by per-document. Iranian nanotechnology researcher's degree of collaboration was 0.96 this indicates, greater tendency of nanotechnology authors towards co-authorship. Considering total collaboration coefficient (0.64), nanotechnology authors have shown tendency to production of scientific collaborative document. The highest collaboration coefficient (0.83) And the lowest collaboration coefficient (0.5) have been allocated to the 1997 and 1991 respectively.

This research aimed to compare the degree of form and vocabulary match between user's subject queries (user vocabulary) and the List of Persian subject headings (system vocabulary) in two subject areas: 1) Agriculture (applied sciences); 2) library and information science, education, and psychology (humanities). The research population included the students at the two faculties of agriculture and education and psychology. Data were collected through observation and transaction log method. Findings showed that in subject queries carried out by students in the faculty of agriculture, the degree of "full match" was 30.9%, of "partial match" was 19.5%, and of "no match" was 49.6%; and in subject queries carried out in the faculty of education and psychology, the degree of "full match" was 37.7%, of "partial match" was 21.1%, and of "no match" was 41.2%. In the two determined faculties, more than 95% of the forms of subject queries accord with those various forms of Persian subject headings more likely used in natural language, including: queries with more than one word; simple subject queries; and subject queries including several words plus conjunctions and prepositions. There was no significant difference between the search language of the two facultie's students in terms of the degree of match between user's subject queries and Persian subject headings regarding vocabulary and form.
