2013年的IF已經(jīng)發(fā)布,細(xì)心的觀眾會(huì)發(fā)現(xiàn),有些雜志IF高的離譜,比如PLANT MOL BIO REP 5.3,而其大哥 PLANT MOL BIO才3.5, 另外組培的那個(gè)雜志 PLANT CELL TISS ORG CUL也是3點(diǎn)多,這種靠瘋狂自引提高自己的IF有意思嗎,可靠嗎?能說明這個(gè)雜志的水平嗎?恐怕大家心里都清楚,所以說IF也不是那么靠譜的。自己行業(yè)內(nèi)什么雜志好自己心里應(yīng)該有點(diǎn)數(shù)的。 現(xiàn)在沒有時(shí)間來查他們今年的自引,把去年整理的發(fā)給大家看看。去年我已經(jīng)注意到這兩個(gè)雜志了,越來越猖狂! 千呼萬喚之中,昨天晚上,確切的說是6月29日凌晨,2011年的SCI Impact factor (IF) 終于出來了,結(jié)果可謂幾家歡喜幾家憂! 生物類(主要指與植物相關(guān))老牌雜志的IF普遍沒有什么增加,甚至有的還略微下降。如plant cell去年9.396,今年破9了,跌到8.987了; plant physiology 由去年6.451略升到今年的6.535;plant Journal去年6.948,今年則降到6.16;planta算是勉勉強(qiáng)強(qiáng)地保住了3分金身破,正好3.0。 與此相反,往常一些名不見經(jīng)傳的低分雜志,今年的IF卻一路飆升,如PLANT CELL TISS ORG去年1.243,今年3.09,超過了老牌雜志PLANTA;PLANT MOL BIOL REP去年0.825,今年卻達(dá)到了2.453;MOL BIOL REP去年1.875,今年卻飆到了2.929,幾近3。這是為什么呢? 難道這些老牌雜志都跟不上潮流了,落后于時(shí)代了? 仔細(xì)研究了一下JCR報(bào)告,才發(fā)現(xiàn)了其中的奧秘?偟膩碚f,這3個(gè)雜志大幅提高IF的方法無他,唯自引也! 先看PLANT CELL TISS ORG,JCR報(bào)告見http://admin-apps.webofknowledge ... PLANT+CELL+TISS+ORG。如下圖: Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 5379 Cites to Years Used in Impact Factor Calculation 1026 Impact Factor 3.090 Self Cites 1375 (25% of 5379) Self Cites to Years Used in Impact Factor Calculation 554 (53% of 1026) Impact Factor without Self Cites 1.422 自引率達(dá)到53%之多,去掉自引后IF只有1.422; 而MOL BIOL REP,JCR報(bào)告http://admin-apps.webofknowledge ... ournal=MOL+BIOL+REP Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 3604 Cites to Years Used in Impact Factor Calculation 2481 Impact Factor 2.929 Self Cites 1366 (37% of 3604) Self Cites to Years Used in Impact Factor Calculation 1153 (46% of 2481) Impact Factor without Self Cites 1.568 自引率為46%,去掉自引后IF只有1.568; 更離譜的是PLANT MOL BIOL REP,http://admin-apps.webofknowledge ... =PLANT+MOL+BIOL+REP Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 2239 Cites to Years Used in Impact Factor Calculation 363 Impact Factor 2.453 Self Cites 276 (12% of 2239) Self Cites to Years Used in Impact Factor Calculation 208 (57% of 363) Impact Factor without Self Cites 1.047 自引率高達(dá)57%,去掉自引率后其IF只有1.047; 反觀其它老牌雜志,如Planta,http://admin-apps.webofknowledge ... ;amp;journal=PLANTA Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 14779 Cites to Years Used in Impact Factor Calculation 1314 Impact Factor 3.000 Self Cites 384 (2% of 14779) Self Cites to Years Used in Impact Factor Calculation 64 (4% of 1314) Impact Factor without Self Cites 2.854 自引率只有4%,去掉自引后其IF仍達(dá)到2.854,正好是PLANT CELL TISS ORG的兩倍,足見JCR的部分IF水分有多高。 隨便再舉幾個(gè)雜志,PLANT SCI,http://admin-apps.webofknowledge ... p;journal=PLANT+SCI Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 9422 Cites to Years Used in Impact Factor Calculation 963 Impact Factor 2.945 Self Cites 212 (2% of 9422) Self Cites to Years Used in Impact Factor Calculation 37 (3% of 963) Impact Factor without Self Cites 2.832 PLANT PHYSIOLOGY AND BIOCHEMISTRY, http://admin-apps.webofknowledge ... PLANT+PHYSIOL+BIOCH, Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 4501 Cites to Years Used in Impact Factor Calculation 786 Impact Factor 2.838 Self Cites 140 (3% of 4501) Self Cites to Years Used in Impact Factor Calculation 27 (3% of 786) Impact Factor without Self Cites 2.740 .在網(wǎng)友的指點(diǎn)下,又發(fā)現(xiàn)了一個(gè)驚天雜志:Energy Education Science and Technology http://admin-apps.webofknowledge ... NERGY+EDUC+SCI+TECH Journal Self Cites The tables show the contribution of the journal's self cites to its impact factor. This information is also represented in the cited journal graph. Total Cites 2992 Cites to Years Used in Impact Factor Calculation 1964 Impact Factor 31.677 Self Cites 2674 (89% of 2992) Self Cites to Years Used in Impact Factor Calculation 1785 (90% of 1964) Impact Factor without Self Cites 2.887 Journal Immediacy Index 單靠自引,能降一個(gè)不到3的雜志提高到31點(diǎn)多,自引率達(dá)到90%之多,這是多大的魄力,何等的瘋狂! 看到這,大家應(yīng)該知道有些雜志IF突然升高的奧秘了,我不明白的是,為什么Thomson Reuters 對(duì)此置若罔聞呢?這樣對(duì)那些老老實(shí)實(shí)的雜志是否不公呢? 這樣的IF還有什么可信度,還有什么參考價(jià)值? |

lz說的這些自引還是可以查得到的,不算太bug 就我所知有一種方式更隱蔽 一個(gè)叫做Journal of Biomedical Nanotechnology的期刊,和一個(gè)叫做 Journal of Nanoscience and Nanotechnology的期刊是相同的出版社,主編好像也是一樣的 奇葩的是,JNN在接受文章時(shí),主編會(huì)讓你引用JBN上的一些有關(guān)的文獻(xiàn),而且推薦6-10篇 從而顯著提高了IF,有沒有大幅自引出現(xiàn) 多和諧,哈哈 |
