标 题: 2004年最新影响因子，IF>5, 从高到低 发信站: 水木社区 (Sat Jun 18 07:00:37 2005), 站内 隆重登场！！！！ PLOS不负众望，成为新星，希望明年能冲过20大关。。 初步感觉Nature系列还是稳中有升，Cell系列继续疲软，老的JBC,JCB,MCB,EMBO继续颓 医学系列的杂志都狂涨，技术类和交叉类的出来都很猛， 比如Plos bio, nature material,syst bio,还有老的nature biotech... 看来每年6月17号(美东时间)出来最新的影响因子没错，去年也是这个时候。 Abbreviated Journal Title ISSN 2004 Total Cites Impact Factor Immediacy Index 2004 Articles Cited Half-life ANNU REV

标 题: Nature对影响因子的评论 发信站: 北大未名站 (2005年07月03日14:30:48 星期天), 转信 Nature对影响因子的评论 送交者: 阿混五 2005年6月23日08:41:15 于 http://www.bbsland.com Nature对影响因子的评论 Editorial Nature 435, 1003-1004 (23 June 2005) Not-so-deep impact Research assessment rests too heavily on the inflated status of the impact f actor. Every year at the end of June, scientific publishers' eyes turn to Philadelp hia, where the Institute for Scientific Inxxxxation (ISI) releases a snippet of data that they crave: the impact factor of each journal. In due course, bureaucrats in research agencies will roll the impact figures into their per xxxxance indicators, and those scientists who worry about such things will q uietly note which journal's number wins them the most brownie points. Attempts to quantify the quality of science are always fraught with difficul ty, and the journal impact factors are among the few numbers to persist. The result is an overemphasis of what is really a limited metric. To obtain the latest impact factors, which were released last week, the ISI number-crunchers added the total number of citations from all the monitored journals during 2004 to items in the journal of interest that were published in 2002 and 2003. They then divided that total by the number of 'citable it ems' — loosely, papers and review articles — that were published in the jo urnal during those same two years. The impact factor is taken by some administrators as a measure of the typica l citation rate for the journal. But for many journals, it isn't 'typical' a t all. Nature's latest impact factor is 32.2, an increase on last year and a high number that we're proud of, but it's one that merits a closer look. For example, we have analysed the citations of individual papers in Nature a nd found that 89% of last year's figure was generated by just 25% of our pap ers. The most cited Nature paper from 2002-03 was the mouse genome, published in December 2002. That paper represents the culmination of a great enterprise, but is inevitably an important point of reference rather than an expression of unusually deep mechanistic insight. So far it has received more than 1,0 00 citations. Within the measurement year of 2004 alone, it received 522 cit ations. Our next most cited paper from 2002-03 (concerning the functional o rganization of the yeast proteome) received 351 citations that year. Only 50 out of the roughly 1,800 citable items published in those two years receive d more than 100 citations in 2004. The great majority of our papers received fewer than 20 citations. These figures all reflect just how strongly the impact factor is influenced by a small minority of papers — no doubt to a lesser extent in more special ized journals, but significantly nevertheless. However, we are just as satis fied with the value of our papers in the 'long tail' as with that of the mor e highly cited work. The citation rate of our papers also varies sharply between disciplines. Man y of Nature's papers in immunology published in 2003 have since received bet ween 50 and 200 citations. Significant proportions of those in cancer and mo lecular and cell biology have been in the 50??150 range. But papers in physi cs, palaeontology and climatology typically achieved fewer than 50 citations . Clearly, these reflect differences in disciplinary dynamics, not in qualit y. The impact factor also mixes citations to diverse types of content: unsurpri singly, review articles are typically the most highly cited, but citations o f our Commentaries, News Features and News & Views articles also contrib ute in a minor way to the numerator (although these items are not counted in the denominator). The net result of all these variables is a conclusion that impact factors do n't tell us as much as some people may think about the respective quality of the science that journals are publishing. Neither do most scientists judge journals using such statistics; they rely instead on their own assessment of what they actually read. None of this would really matter very much, were it not for the unhealthy re liance on impact factors by administrators and researchers' employers worldw ide to assess the scientific quality of nations and institutions, and often even to judge individuals. There is no doubt that impact factors are here to stay. But these figures illustrate why they should be handled with caution. |
