Usually, this is done to benefit the readership of and contributors to the journals, as disciplines expand or become more specialized, or as a journal’s aims and scopes are modified. And, it is just in 2008 that JZUS-B was covered in Science Citation Index-Expanded (SCI-E) of Thomson Ruters, and as the first university journal, received a grant (No. 30824802) from the National Natural Science Foundation of China. And also JZUS (A&B) have been the first journals from China to become members of CrossCheck in 2008 ( http://www.crossref.org/crosscheck_members.html http://www.crossref.org/crosscheck_members.html ) in order to prevent from plagiarism and ensure the copyright and credibility of the contributing authors and their articles to JZUS (A&B) . As newly included in SCI for no more than three years that is the period to calculate the classical Journal Impact Factor (JIF), JZUS-B has no official IF released by Thomson Ruters until July in 2011. However, it is crucial to make citation analysis and IF prediction of JZUS-B . In fact, since 2004, we have been collecting citation data from Web of Science to build JZUS (A&B) citation database ( http://www.zju.edu.cn/jzus/download/Wu Xiufang.rar http://www.zju.edu.cn/jzus/download/Wu Xiufang.rar ). From this database, we can obtain a lot of important information related to JZUS-B ’s development, as shown in Figs. 1 1 ~ 2 2 and Table 1 1 . We found that JZUS-B ’s articles were mainly cited by these journals: Colloids and Surfaces B-Biointerfaces (13 citations), Brazilian Archives of Biology and Technology (9 citations), Comptes Rendus Biologies (9 citations), Journal of Agricultural and Food Chemistry (8 citations), Pakistan Journal of Botany (6 citations) and Journal of Hazardous Materials (6 citations), etc. And also we analyzed that the non-self-citation and the self-citation rates related to the predicted JZUS-B 2008 IF, are 83.8% (165/197) and 16.2% (32/197), respectively; the self-citation rate is far lower than that ( > 20%) of other newly SCI-covered journals at the same status. http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543565&type= http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543565&type=small http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543565&type=middle http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543565&type=small http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543567&type= http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543569&type= http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=23543567&type=middle It is possible to predict IF for an upcoming year with reasonable accuracy using the Garfield’s JIF calculation formula. When estimating the JZUS-B 2008 IF, the numerator is the number of all citations in 2008 to articles that had been published in JZUS-B in 2006 and 2007 (total 197), and the denominator is the number of citable articles published in JZUS-B in 2006 and 2007 (total 292). The current IF (on 12-23-2008) is 0.675 (197/292). With the 4-week tracking method (Ketcham, 2007 2007 ; Wu et al., 2008 2008 ), we can also forecast JZUS-B 2008 IF in the range of 0.737~0.915 (averaged value is 0.807), which is higher than the predicted JZUS-B 2007 IF (211/371=0.569) (Table 2 2 ). In turn, the predicted JZUS-A 2008 IF is in the range of 0.222~0.274 (average IF is 0.236), also much larger than its predicted 2007 IF, 0.159 (Zhai et al., 2009 2009 ). As Journal Citation Reports (JCR) processing deadline is around mid-February following the JCR year, we can estimate IFs at least four months before their official release in June or July. Note: Predicted IF max : 0.675+2×0.120=0.915; Predicted IF min : 0.675+2×0.031=0.737; Predicted IF avg : 0.675+2×0.066 (ΔIF avg )=0.807 Date Current IF ΔIF for 4 weeks 02-23-2008 4/292=0.014 03-23-2008 24/292=0.082 0.068 04-19-2008 41/292=0.140 0.058 05-18-2008 55/292=0.188 0.048 06-15-2008 74/292=0.253 0.065 07-13-2008 86/292=0.294 0.041 08-09-2008 121/292=0.414 0.120 09-21-2008 153/292=0.524 0.110 10-19-2008 162/292=0.555 0.031 11-15-2008 175/292=0.599 0.044 12-13-2008 197/292=0.675 0.076 Two major reasons can explain the recent uptrend of JZUS-B ’s IF: strict international peer review system and improving innovative information. Moreover, it is reasonable to anticipate a further increase in JZUS-B IF for 2009. References CM Ketcham . Predicting impact factor one year in advance .
