This research aimed to investigate the relationship between critical thinking and motivation with intentional Internet search. The research sample included 196 students in bachelor degree and 28 students in master degree programs offered by Hygiene Faculty at Mazandaran University of Medical and Health Sciences. The method used in this research was based on analytical survey and the tools used in collecting data for critical thinking survey was based on California “form B” standardized by Khalili. Motivation was measured by the subscales of Motivated Strategies for Learning Questionnaire (MSLQ) which was developed by Pintrich and Garcia and Behavioral Internet Search Questionnaire developed by Wu was used for measuring intentional Internet search. Findings of this research indicated that there was no meaningful relationship between critical thinking and intentional Internet search amongst the targeted population in this research; however، the researcher theory was based on existence of a meaningful relationship between motivation and intentional Internet search approved. Measured level of critical thinking within targeted population averaged to 10/19 which was lower than standardized process that yields 15/59. This indicated that research population’s critical thinking was weak. Measured level of motivation amounts to 82/10 and this was higher than the average. This indicated that population under research possessed relatively good motivation. Measured level of intentional Internet search averages to 58/51 which was at the mean interval for this variable، therefore this skill was on par with the average level. Review of relationship between variables in the research with variables of gender demographic، educational courses، section and educational discipline indicated that there was indeed a meaningful connection between critical thinking and variables of demographic of degree level and discipline. There was a meaningful relationship between motivation and demographic variables of degree and discipline and the average of motivation factor in master degree was higher than the bachelor degree. Intentional Internet search had a meaningful connection with respect to education level and discipline..

In the era of globalization and intense competition، the research and development national organizations have been in the strong dilemma for the efficient activities. When part of the national capital would be invested on research and development centers، these centers are responsible of the answer for their performance. The purpose of this study was to evaluate the relative efficiency the Iran''s research and development performance in the region in both sectors: the production and publishing of knowledge using Network DEA. So the research and development activities from 14 countries region were extracted to assess their relative efficiency. In the production sector، the inputs such as enrollment rates in the sciences and engineering fields، number researchers، costs research and development and the outputs such as number patents، number papers engineering and scientific were used. In sector publishing of knowledge، the inputs such as number patents، number papers engineering and scientific and outputs such as export technology modern and mean reference to the articles were used. The results showed that in the sector of the production of knowledge، four countries and in the sector of the publishing of knowledge، nine countries were inefficient. It was noteworthy that Iran in the sector of the production of knowledge did not have the proper place between the selected countries، but in the sector of the publishing of knowledge it was able to gain maximum efficiency from the DEA models.

Organizations have the different patterns of behaviors on management practice and the use of systems during their life cycle and due to rapid growth of information technology، the application of appropriate technologies is becoming an essential part of business، as well. The adaptation of appropriate management systems on different stages of organizational life period will affect on sustainability of the firms and success to move to next stage and alignment and collaboration schema of IS/IT and business requirement affects on management effectiveness at every stage. This research investigated the significance of relationship between management behavior and IS/IT usage and the generic approach selected by companies. The results showed that organizations have chosen different approach during their life cycle and as they faced with unique challenges on each stage، a common practice on using information technology and applications became part of organizational life cycle. A generic model for information technology usage on organization life cycle was also developed that will assist organizations to select and develop IS/IT plans which addresses the requirements for each stage of life cycle.

Today، one of the criteria for the assessment of development of countries، international organizations and world economy is the achievement of the level of ICT. In addition، a fair distribution of this tool for better and update services is very important. The purpose of this study was to assess the spatial distribution parameters and hardware experts in the areas of ICT and informatics users fourteen municipality of Isfahan. Descriptive research method was analytic and for ranking، grading and determination of distribution models، statistical indicators Mac Granahan، cluster analysis and factor differences were used. The results showed that the different regions of Isfahan Municipality of enjoyment of these indicators were not equal to. Generally، these areas formed four classes to enjoy، have relatively less ill، have enjoyed and have been classified. The scattering coefficient showed large differences in the type and distribution of these indices in Isfahan Municipality there..

The purpose of this research was to make exam the indexing and ranking of XML content objects containing Dublin Core and MARC 21 metadata elements in dynamic online information environments by general search engines and comparing them together in a comparative-analytical approach. 100 XML content objects in two groups were analyzed: those with DCXML elements and those with MARCXML elements were published in website http: //www. marcdcmi. ir. from late Mordad 1388 till Khordad 1389. Then the website was introduced to Google and Yahoo search engines. Google search engine was able to retrieve fully all the content objects during the study period through their Dublin Core and MARC 21 metadata elements; Yahoo search engine، however، did not respond at all. The indexing of metadata elements embedded in content objects in dynamic online information environments and different between indexing and ranking of them were examined. Findings showed all Dublin Core and MARC 21 metadata elements by Google search engine were indexed. And there was not observed difference between indexing and ranking DCXML and MARCXML metadata elements in dynamic online information environments by Google search engine.

The purpose of this study was to investigate the application rate of post modern management components among managers and librarians in the libraries of Isfahan state universities and the research method was descriptive survey study. The population consisted of 166 managers and librarians in the libraries of Isfahan state universities. Data was gathered using a researcher-made questionnaire and SPSS software was used to analyze the data. The findings showed that the application rate of all the components in the existing situation were lower than the average and in the ideal situation were higher than average. The results of Hotteling showed that the effect of the components in the existing situation and in the ideal situation were not the same. The findings also showed that there was significance in the existing situation based on demographic factors gender and place of work and in the ideal situation based on demographic factors course of study and place of work (p<0.05).

The aim of this research was to investigate the effect of co-authorship and self-citation on the citation rates of Iranian indexed articles in Web of Science (WoS). Research population included Iranian indexed articles in WoS in 2007 which had been received at least one citation. Numbers of articles in the time of research (October & November 2010) was 7355، which 390 of them، using stratified random sampling، was selected as sample. Research results showed that co-authored articles have received more citations than single-authored ones and this difference was statistically significant. On the other hand، self-citation exclusion has significantly reduced the citation rates of both co-authored and single-authored articles. After self-citation exclusion، existing difference between citation rates of co-authored and single-authored articles lost its significance. So، it can be concluded that self-citation exclusion led to reduction of citation rates of Iranian indexed articles in WoS، but this exclusion affected co-authored articles citation rates more than single-authored ones. In other words، high citation of Iranian co-authored articles in comparison with single-authored articles has been affected mainly by self-citation، not by foreign citation. This finding، which was our contribution، contradicted with results of previous researches.

The present study investigated the analysis of search engines and meta search engines adoption process by University of Isfahan users during 2009-2010 based on the Rogers'' diffusion of innovation theory. The main aim of the research was to study the rate of adoption and recognizing the potentials and effective tools in search engines and meta search engines adoption among University of Isfahan users. The research method was descriptive survey study. The cases of the study were all of the post graduate students of the University of Isfahan. 351 students were selected as the sample and categorized by a stratified random sampling method. Questionnaire was used for collecting data. The collected data was analyzed using SPSS 16 in both descriptive and analytic statistic. For descriptive statistic frequency، percentage and mean were used، while for analytic statistic t-test and Kruskal-Wallis non parametric test (H-test) were used. The finding of t-test and Kruscal-Wallis indicated that the mean of search engines and meta search engines adoption did not show statistical differences gender، level of education and the faculty. Special search engines adoption process was different in terms of gender but not in terms of the level of education and the faculty. Other results of the research indicated that among general search engines، Google had the most adoption rate. In addition، among the special search engines، Google Scholar and among the meta search engines Mamma had the most adopting rate. Findings also showed that friends played an important role on how students adopted general search engines while professors had important role on how students adopted special search engines and meta search engines. Moreover، results showed that the place where students got the most acquaintance with search engines and meta search engines was in the university. The finding showed that the curve of adoption rate was not normal and it was not also in S-shape. Morover، among simple and advanced pages of Google، a specific bias toward simple search pages could be seen in users. This part of the study confirmed Rogers’ theory. Other results of the study indicated that renouncement of innovation was not only in decision phase. This part of the investigation was in conflict with Rogers’ theory.

Organizational maturity is the ability of retain or development of performance during the long-term and it is the result of the continued satisfaction of organization’s stakeholders during the time. Organizational maturity will occur through identification of environmental changes and upgrading of organization’s strategic plans and visions. Organizations shall be able to predict the environment and adapt their planning to it. Therefore، for achieving maturity، organizations shall monitor its environmental factors changes continuously. On the other hand، today knowledge is the only confidential source for creating the sustainable competitive advantage in organizations. In addition، knowledge is a tool for capture and retain of sustainable competitive advantage for organizations and they find the importance of knowledge as a strategic source، more and more. In this research، organization’s maturity and knowledge management models have been introduced and a model for measurement of maturity level of organizations has been presented. This research approach was to use knowledge management activities for managing of environmental changes knowledge to creating of organizational maturity. To proving of the presented model، maturity level of 112 automotive part producers has evaluated. Finally، the results showed that the researchers'' hypotheses were true and knowledge management activities and organization’s maturity were correlated. For hypotheses test and measuring the questionnaires validity Pearson correlation coefficient has used.

Web is developing very fast. It is a resource to publish electronic information. There is no standard on the web so it is important that we identify information quality on the web. To this aim، this survey first identified fourteen web information quality criteria and then a questionnaire based on these criteria was used to investigate the amount of attention to and application of web information quality criteria among post-graduate students of Shiraz University while searching for information in the web. Data was analyzed using inferential statistics such as repeated measures. The results indicated that the amount of attention to the web information quality criteria differed for each of the criteria on the basis of the user''s information needs، knowledge and experiences، their aims of searching for information and the amount of their tolerance for biased information. In general، no significant differences were found on the amount of attention to information quality criteria among different disciplines، MA and PhD levels and the sex of graduates in Shiraz University.

The output of scientific products represents the efforts of scientific and industrial communities. The study on this output shows scientific attitudes and approaches of a community towards world of science. Quantitative studies can give a representation of the size and extent of the scientific efforts of researchers in special occasions، or a particular society. Patents are one of these important outputs. In this study، the names of Iranian inventors were extracted by carrying a combined search and the analysis of patent data available through Europe Patent Office (EPO)، the United States Patent and Trademark Office (USPTO)، Japan Patent Office (JPO)، and the World Intellectual Property Organization (WIPO) databases. Inventors amount of scientific products were also evaluated by using citation indexes in Thompson Reuters (formerly ISI) Web of Science. Content analysis research method was adopted. Results of this study reported no significant correlation was found between scientific output and patent application. Findings also indicated a 6. 5 percent contribution of patent researcher in comparison with non-patent researchers of Iranian indexed articles by Web of Science.
