See for further explanation: "Visualization of the Citation Impact Environment of Scientific Journals: An online mapping exercise," Journal of the Amererican Society for Information Science and Technology (forthcoming) <http://www.leydesdorff.net/jcr04/index.htm> <pdf version: http://www.leydesdorff.net/jcr04/jcr2pajek.pdf> The 2005 matrices are based on taking the one-percent threshold of "total citations" *after* correction for within-journal citations. This main-diagonal value is sometimes so large that it overshadows the environment and therefore it is no longer included in setting the threshold for the delineation of the set. * apologies for cross-postings ________________________________ Loet Leydesdorff Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam Tel.: +31-20- 525 6598; fax: +31-20- 525 3681 [log in to unmask] ; http://www.leydesdorff.net/ The Knowledge-Based Economy: Modeled, Measured, Simulated. 385 pp.; US$ 18.95 <http://www.universal-publishers.com/book.php?method=ISBN&book=1581129378> _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
