Abstract  

This study investigates the knowledge diffusion patterns of Nanoscience & Nanotechnology (N&N) by analyzing the overall research interactions between N&N and nano-related subjects through citation analysis. Three perspectives were investigated to achieve this purpose. Firstly, the overall research interactions were analyzed to identify the dominant driving forces in advancing the development of N&N. Secondly, the knowledge diffusion intensity between N&N and nano-related subjects was investigated to determine the areas most closely related to N&N. Thirdly, the diffusion speed was identified to detect the time distance of knowledge diffusion between N&N and nano-related subjects. The analysis reveals that driving forces from the outside environment rather than within N&N itself make the foremost contributions to the development of N&N. From 1998 to 2007, Material Science, Physics, Chemistry, N&N, Electrical & Electronic and Metallurgy & Metallurgical Engineering are the key contributory and reference subjects for N&N. Knowledge transfer within N&N itself is the quickest. And the speed of knowledge diffusion from other subjects to N&N is slower than that from N&N to other subjects, demonstrating asymmetry of knowledge diffusion in the development of N&N. The results indicate that N&N has matured into a relatively open, diffuse and dynamic system of interactive subjects.

Abstract  

Citation analyses were performed for Australian social science journals to determine the differences between data drawn from Web of Science and Scopus. These data were compared with the tier rankings assigned by disciplinary groups to the journals for the purposes of a new research assessment model, Excellence in Research for Australia (ERA), due to be implemented in 2010. In addition, citation-based indicators including an extended journal impact factor, the h-index, and a modified journal diffusion factor, were calculated to assess whether subsequent analyses influence the ranking of journals. The findings suggest that the Scopus database provides higher number of citations for more of the journals. However, there appears to be very little association between the assigned tier ranking of journals and their rank derived from citations data. The implications for Australian social science researchers are discussed in relation to the use of citation analysis in the ERA.

Abstract  

This study was survey on citation research of Open Access (OA) journals in English papers of Iranian universities journals during year 2007. The main purposes of this paper were: to examine the state of English papers in Iranian journals in Thomson Scientific Master Journal List (TSMJL); and to analyze their visibility through citations to OA journals in DOAJ database. In fact, the researcher has used of citation analysis technique of bibliometric and large-scale sociometric analyses on about 16,219 citations. The method followed in the first part of this study is obtaining data from e-journal articles which indexed in TSMJL, conducting descriptive analyses, and reporting the findings in tables and figures. In the second part of the study, DOAJ database is used to behaviour cited reference searches and other citation analyses. It found that there are 960 Iranian print-based journals and only 37 Iranian Journals was indexed in TSMJL. Sixteen English Journals in TSMJL of eight Iranian universities. Throughout sixteen journals only one journal didn’t publish during 2007 and there were 704 articles all over the fifteen journals. Using large-scale sociometric analyses on about 16,219 citations all over 15 journals, it is notable that number of journals without citation to DOAJ was 3,101 (99.7%) and the number of journals with citation to DOAJ was 9 (0.3%). It shows that there was huge difference between the journals which had citing to DOAJ and without citing to DOAJ.

Abstract  

The paper investigates the online citation analysis possibilities and limitations. The following online processing tools: RANK, MAP, and TARGET, provided by Dialog, are incorporated in order to perform analyses of citations to and from isolated sets of documents as well as to carry out diachrone journal analyses. These, analyses imply further to determine journal impact factors of ISI journals. Measures of the scope of internationalisation of journals are proposed and demonstrated. By the combined application of the RANK and TARGET commands we demonstrate a hitherto overlooked possibility of working with bibliographic coupling online and mapping of scientific fields.
