The following results using Pearson correlation coefficient, there was a positive relationship (direct) between usage rate of information and communication technology by faculty members of Ferdowsi University of Mashhad and their educational and research performance.

Results of scientific research are diffused by scientific journals; therefore these journals have a significant role in development of scientific disciplines and are considered as a criterion for their growth. Paying attention to quality and quantity of these journals is a base for planning of academic disciplines promotion. This research was conducted to investigate the quantity of agriculture and natural resources journals in Iran, their indexing status in various databases, and ranking disciplines and publishers of these journals by applying a descriptive – comparative research methodology. Finally, based on the research findings, some applicable recommendations for upgrading the national scientifi journals as well as in agriculture and natural resources fields have been presented in this paper.

The objective of this research was to compare co authorship networks of Iranian articles in Library and Information Science (LIS), (MNG) and Economics (ECO) in ISI during 2000 research was a bibliometric study and used network analysis (using Pajek) for the visualization of co Data included all articles written by at leas and indexed in Social Science Citation Index (SSCI) for the fields of LIS, PYSCH, MNG and ECO. Different indicators such as collaborative index (CI), degree of collaboration (DC) and collaboration coefficient (CC) were calculated for e Results showed that two or three authors were the most common number of authors per paper and authors of PYSCH tended to have more multi-authored articles compared to the other disciplines. LIS had the lowest rank regarding CC. MNG had the densest and PYSCH had the sparsest co-authoship network. Iranian authors in the field of PSYCH mostly collaborated with USA while LIS and MNG authors tended to collaborate with UK, and ECO authors tended to collaborate with Canadians.

This research investigated the possibility of the eplacement of printed reference sources by free electronic eference sources. A content analysis method was carried out on 25 printed reference sources (out of 1364 titles available in Ferdowsi University libraries) including 5 encyclopedias, 5 atlases, 5 biographies, 5 dictionaries and 5 directories. For each printed ource, a similar electronic one was selected and examined. In both printed and free electronic reference source, 5 entries (250 in total) were analyzed according to checklists to see if they match the content as well as the structural criteria. The scores obtained to each entry in free electronic sources as well as those in printed ones were compared. Findings showed that: 1. There is a significant difference between the scores obtained from the entry analysis in free electronic sources and those in printed sources implying that free electronic sources have more capabilities in answering reference questions. Therefore, free electronic reference sources have considerable capacity to replace printed reference sources. 2. There is significant difference between the scores obtained from the analysis of the quality of indexes of the content of printed sources as well as those of free electronic ones. From the content point of view free electronic reference sources are more capable in fulfilling reference questions than their equivalent printed sources. 3. There is a significant difference between scores obtained for the structure of printed sources and electronic sources. From a structural point of view, free electronic reference sources have more capacity to fulfill reference questions than their similar printed reference sources.

Increasing environmental challenges have directed organizations toward to two facilitators: human resource management and information technology. In this paper, the researchers intended to examine the relationship between the information technology and human resource management. The research design was descriptive-practical. The population of study was the human resource professionals and R & D staffs at Central Bank IRI. The instrument for data collection was questionnaire. The results established the relationship between information technology application and performance of human resource management. However, findings showed that despite this relationship, there was the misalignment between these two facilitators in that organization, and information technology was still considered as a supportive function in organization. Spearman correlation test was used for examining hypothesizes. At the end, SEM was used for testing mode.

The purpose of this survey study was to determine factors influencing adoption of information technology using Technology Acceptance Model (TAM) among vocational agricultural teachers in Kermanshah province. Davis's questionnaire was back-translated and used to collect data. The research instrument was validated by a panel of experts and reliability was checked using Cronbach's alpha coefficient yielding 0.7 for all sections. A census of 52 agricultural vocational teachers across six agricultural vocational schools (Kermanshsh, Islam-abade Gharb, Songhor, Ravansar, Ghasreshirin, Bisetoun) participated in the study. The results of path analysis revealed that perceived usefulness and attitude towards using information technology had a positive and significant correlation with teacher's use of information technology. Moreover, perceived ease of use predicted attitude towards using information technology. The result of this study has implications for policy makers involved in agricultural vocational schools in that teachers can be made aware of effectiveness of information technology in teaching and learning process. In addition, mastery learning can enhance teacher's utilizing information technology.

First of all specialized keywords were defined in the list based on the sites were indexed. 86% of the population tested, believed that the time spent searching for information SISE was lower than other general search engines and 80% believed that quality and accuracy of search results is SISE were more than other search engines.

This article has evaluated the impact of using Meta tag on the improvement of information retrieval of the World Wide Web. So it reviewed the research papers that have examined Meta tag as a means to enhance information retrieval. Results showed there were some researches that have confirmed the using of Meta tags was efficient for improving information retrieval of the web, but results of a research that has done by Mohamed (2006) indicated no significant difference in the rank of pages that include metadata and those that don’t include any metadata. Therefore more studies should be done in this field. In general, Meta tags can provide site owners and authors with a degree of control over how a web page is indexed and this is a considerable advantage that it shouldn’t be ignore easily.

With regards to important role of universities’ websites, this article aimed to study top universities of the Islamic countries using webometrics methods. Research data were extracted from AltaVista search engine and WEBOMETRICS website. In this study, top universities of the Islamic countries were ranked with some indexes such as number of links, web impact factor, world rank, size, visibility, rich files and scholar. Results showed that there was a significant relation between web impact factor with some indicators such as world rank, size, rich files and scholar, but there was not any significant relation between web impact factor and visibility of the website. Strong significant correlation between top universities of the Islamic world countries websites’ world rank and their ranks based on GDP was another result that we can mention in this study.

The aim of this paper was to evaluate the relationship between six indexes of knowledge management and webometric Scale.

Extent of adaptation of Persian Agricultural scientific journals which are publishing in Iran with ISO publishing standards was evaluated in this research. The information items which were necessary to be presented in different sections of Agricultural scientific journals were examined. Items which were needed to be present in cover page, content, title page, running title, and endnote, abstract, first page of an article, references and its structure were among the information items. 47 Agricultural scientific journals were publishing until February 2009 consisted of the research population. Descriptive survey method is used. Results showed the adaption rate with ISO standards in research population was 53.47 percent. There was no private publisher which publishes agricultural scientific journals. The extent of adaptation with ISO standards was high in journal sections such as abstracts and keywords.

This research analyzed 20 Iranian English medical scientific journals indexed in some elected creitable databases from 2001-2004/ 1380-1383. The results showed that from these 20 journals, only 5 ones having 687 articles were indexed in databases. Daru Journal was the first journal. The most of articles were indexed in EMBASE and none of journals were entered in PUBMED and WEB OF SCIENCE. Most percentage of articles was in the field of Pharmacology then Communicable Diseases and Pediatrics. And the articles with 3 authors were the most articles.

Impact Factor is one of the most important tools to evaluate journals in ISI. In this article, have been tried to extract factors increase the journal's impact factor via studying the literatures and also introduce the factors that may be effective in reducing the weaknesses. The effect of factors such as interval, national, and individual motivations to increase the impact factor of journals and also issues that should be considered when calculating the impact factor, comprised some of the contents of this paper. At the end of the study, in order to evaluate the effect of using the optimal impact factor of journals, some recommendations were presented.

Robert K. Merton has made up the expression of “Matthew effect" in sociology of Science that explains how the eminent scientists frequently get more acknowledgment than unknown researchers, even if their work was similar. The objective of this study is to analyze and visualize the influence of “Matthew effect" on the quantitative (papers) and qualitative (citations) of scientific publications originated by Iranian Medical Sciences Universities throughout 2002 – 2006. The method of current study was an analytical-descriptive review. All data about publications originated by Iranian Medical Sciences Universities were extracted from the database of Web of Science (WoS). The citations received by Medical Sciences Universities were extracted from the Citation Report. The relationship between the publications and citations was plotted by Excel. We found a non-linear correlation between the publications and citations of Iranian Medical Universities. The first class and other universities group showed a positive impact related to the Matthew effect; whereas this relationship among second class universities and third class universities were negative. Tehran University of Medical Sciences got the first place on the ranking order based on the scale independent indicator while Bushehr Medical Science University was the last one. Analysis of data indicated that there was a non-liner relationship between Iranian scientific profiles and the citations that they received. The Scale-independent Indicators were the most reliable metrics for normalizing the ranking of universities.

Aim of this applied research was to extract evaluation criteria of Iranian LIS (Library and Information Science) weblogs. Current research using analytical-survey method and in some stages Webometrics methods evaluated 107 sample weblogs. These weblogs were selected from 222 weblogs that had been submitted in directory of ILIS weblogs. This research made a checklist using literature review, expert's attitude and evaluation criteria of websites. This checklist was used for evaluation sample weblogs after standardizing. Finally a checklist was prepared that included 23 factors for evaluation and ranking of ILIS weblogs.. Finally, current research has suggested that this checklist can be used for judgment in carnivals of chosing top weblogs

By using citation analysis, this article has studied humanities journals of Persian Journal Citation Report (PJCR) during 2003-2007. In this research "Impact Factor" and "Immediacy Index" of these journals were investigated and top publishers were determined according to the Impact Factor indicator. Findings showed that more than 75% of these journals have Impact Factor during mentioned years, while only 30% journals have Immediacy Index. Comparing the average Impact Factor of humanities journals with other fields showed the higher Impact Factor in this field.

Over the past decades, a number of measures for determining the impact of scientific journals were introduced and utilized. The number of citations and Impact Factor value are the indicators have been applied a lot in this area and are of a high reputation in scientometrics. In addition to these indicators, some apt indicators have been introduced to measure the impact of publications which "Eigenfactor" and "Article Influence" are the newest ones. Eigenfactor is a measure of importance and prestige of a journal in scientific community and Article Influence is a measure of average impact of an article among other articles in a journal. The main discussion in present study was on Eigenfactor which besides presenting an introduction and an explanation to this factor, its features and characteristics and its differences with Impact Factor and its calculation method have been explained in detail. Considering the fact that calculating "Article Influence" requires the value of Eigenfactor, this indicator has been shortly explained as well.

Increasing websites quantity, specially scientific websites, there were many researches with concern of link analysis using webometrics by librarian and other scholars in different academic majors around the world. The purpose of this article was link analysis of all link analysis related papers from the beginning to February 19th 2009. The research based on Weiner, Amick, and Lee searching model in 2008, this study included 96 refereed papers extracted from international databases like Springer, Proquest, Sage, Emerald, IEEE, Science Direct and national databases such as Magiran and SID. These papers were studied focusing on their different parts like authors, affiliated organizations, purpose, methods, tools, keywords, date of publishing, publication, indexing databases and their suggestions. Moreover, analyzing those papers and studying any related models were the other purposes of the current article. The findings have been categorized and analyses in ten different sections.

This study investigated six engineering scholarly journals and focused on scientific collaboration pattern, coefficient collaboration, Iranian international collaboration, and citation analysis. Findings showed that Iranian researchers authored 75.4% of articles themselves and 24.6% of articles with contribution of researchers from 25 countries worldwide. 367 articles that contributed by 1052 authors were studied. On average three researchers collaborated per article. Out of 1052 contributors, 814 affiliated to Iranian universities and 238 writers belonged to other countries. The results showed Indian researchers were more active than others were. Ranking universities in terms of numbers of articles showed that Iran University of Science and Technology obtained the first place. Coefficient collaboration disclosed the fact that there was a high tendency towards international collaboration e.g. the coefficient collaboration of Iranian Journal of Biotechnology was 0.668. In general, the findings would be helpful for journal’s editorial boards in engineering fields to improve their policies.

Finding free e-journals is very difficult in web environment, because these types of journals are all scattered and they are rarely found in traditional bibliographic sources. Therefore, locating and their retrieval are hard. Then it is not easy to disseminate the accredited ones. The aim of this study was to determine the most accredited free English e-journals in medical sciences. The research methods were content and link analysis. In order to collect the data, a checklist has been used which its validity has been confirmed. The research population consisted of 700 free electronic journals of medical sciences which were collected from two reputable websites. Using qualitative study on the websites of these journals, the number of eligible journals in this research decreased to 269 journals. In the next step, Journal's websites has been analyzed with webometrics methods. Then, utilizing core journal formula, the accredited ones were determined. Results showed that "New South Wales Public Health Bulletin" in Health, "Online Journal of Rural Nursing and Health Care" in Nursery, "BMC Oral Health" in Dentistry and "Brazilian Journal of Medical and Biological Research" in Medicine were the most accredited journals in term of in links. Also, "International Journal of Integrated Care" in Health, "BMC Nursing" in Nursery, "Journal of Oral Science" in Dentistry, "The New York State Dental Journal" and "Journal of Oral Science" were the top free e-journals in term of web impact factor.

The purpose of this research was to examine the validity of Lotka and Pao’s laws with authorship distribution of "Computer Science" and "Artificial Intelligence" fields using Web of Science (WoS) during 1986 to 2009 and comparing the results of examinations. This study was done by using the methods of citation analysis which are scientometrics techniques. The research sample includes all articles in computer science and artificial intelligence fields indexed in the databases accessible via Web of Science during 1986-2009; that were stored in 500 records files and added to "ISI.exe" software for analysis to be performed. Then, the required output of this software was saved in Excel. There were 19150 articles in the computer science field (by 45713 authors) and 958 articles in artificial intelligence field (by 2487 authors). Then for final counting and analyzing, the data converted to “Excel” spreadsheet software. Lotka and Pao’s laws were tested using both Lotka’s formula: (for Lotka’s Law); also for testing Pao’s law the values of the exponent n and the constant c are computed and Kolmogorov-Smirnov goodness-of-fit tests were applied. The results suggested that author productivity distribution predicted in “Lotka's generalized inverse square law” was not applicable to computer science and artificial intelligence; but Pao’s law was applicable to these subject areas. Survey both literature and original examining of Lotka and Pao’s Laws witnessed some aspects should be considered. The main elements involved in fitting in a bibliometrics method have been identified: using Lotka or Pao’s law, subject area, period of time, measurement of authors, and a criterion for assessing goodness-of-fit.
