Adoption and diffusion of innovation is one of the indicators of community progress. Innovation is a process in which ideas and new methods are created or developed. The aim of this study was to visualize the scientific structure of innovation diffusion during 1990 – 2011. The research method was scientometrics. During the period of 1990-2011, 3180 records were extracted in WoS and necessary analyses were performed on them. Results showed that the collaboration coefficient from 0.204 in 1990 raised to 0.508 in 2011 and the average of collaboration coefficient was 0.378 for the whole period. Due to the critical value at confidence level of 95% (0.0177> 0.8578), it can be said that the present work is in accordance with Lutka’s law. The fields of Management with 796 records (25%), Commerce with 546 records (17.2%), and Economy with 428 records (13.5%), ranked first to third respectively in order to diffusion of innovation research publishing. among 81 countries that have produced documents related to the diffusion of innovation, findings showed that over 57 percent were produced in the US and England. Iran with a production of 7 records (% 2.0) in this field ranked 34th. The present study revealed significant correlation existing between cumulative annual frequency of scientific outputs, and year of study. An exponential regression was applied to model the high correlation between cumulative number of documents and the year of study. Using the regression equation, it can be estimated that in 2015, the number of scientific publications on this topic will be twice of the number of publications in 2006. Finally, by the scientific mapping of innovation diffusion on a global basis (GCS), eight clusters were identified and introduced.

This research tried to explore and rank the critical success factors of knowledge management implementation in academic libraries in Yazd. This analytical survey was conducted on the 60 librarians in Yazd academic libraries in 2013. The data was collected by a researcher-made questionnaire of which the validity was confirmed by a group of specialists, and reliability was confirmed by Cronbach’s Alpha that was calculated to be 0.909. The status of critical factors in implementing of Knowledge Management was determined by means of a one-sample t test, and the priority of critical factors was determined by administration of the Friedman Test. among the critical factors considered in implementation of knowledge management, only two factors, namely organizational culture and technology, were in a good situation; also, from the point of view of affecting the implementation of knowledge management in academic libraries, these two factors proved to be in the first priority as well among all of the critical factors. With respect to the importance of academic libraries in achieving the educational and research goals of universities, and the role of knowledge management in attaining these goals, the results gained did not prove to be satisfactory. This indicates the necessity of more serious consideration of the universities’ authorities regarding implementation of KM.

Goals: The purpose of this paper is to investigate organizational barriers effecting on implementation of knowledge management in Khouzestan public libraries. These barriers consist of lack of trust in the organization, hierarchical and non-flexible, non-belief and support for the involvement of senior management and the lack of incentive systems. the Study populations consist of 260 librarians, 150 of which are selected randomly as sample. Data collection tool is questionnaire that to assess its validity and reliability, confirmatory factor analysis and a reliability measure of Cranach's Alpha (0/896) was used. Confirmatory factor analysis and Lisrel software was used to test the hypotheses. all hypotheses of this study were accepted. The Results of the confirmatory factor analysis showed that all dimensions of organizational barriers (namely lack of trust in the organization, hierarchical and non-flexible, non-belief and support for the involvement of senior management and the lack of incentive systems) have acceptable factor bars. No belief and support for the involvement of senior management have the strongest effect with 0.72. organizational barriers such as lack of trust in the organization, hierarchical and non-flexible, non-belief and support for the involvement of senior management and the lack of incentive systems influence knowledge management have failed.
