期刊更名是期刊界经常遇到的一个问题,所以JCR有一套相对成熟的关于期刊更名的处理办法。相关英文原文如下:
Title Changes and Citation Metrics
After a title change, two JCR years must pass before the new title fully replaces the previous title in JCR. In the first year after a journal title change, the new title is listed with an Immediacy Index but no impact factor because the article count for the two preceding years, used in Impact Factor calculations, is zero. The superseded title is listed with a normal two-year Impact Factor. One year later, JCR lists separate impact factors for the new title and for the superseded title, but only the new title will have an Immediacy Index. In this second year, the Impact Factor for a new title may be lower than expected because the article count includes only earlier articles. Similarly, the Impact Factor for the superseded title may be higher than expected because it is based upon only older articles. To calculate a unified Impact Factor, you can total the cites to the two previous years and divide that by the sum of the article counts for the two titles. For a listing of journal title changes, where both the new title and the superseded title appear in JCR, see the Journal Title Changes page, which is accessible from the Journal page, the Journal Search page and the Summary List page.
举个例子说明一下吧:
CHINESE PHYS | changed to | CHINESE PHYS B | 2008 |
中国物理从2008年更名为中国物理B辑。
JCR2008(2009年6月19日公布)中,就会同时查到CHINESE PHYS和CHINESE PHYS B,其中CHINESE PHYS有影响因子没有立即指数,CHINESE PHYS B只有立即指数没有影响因子。
JCR2009(2010年6月18日公布)中,也会同时查到CHINESE PHYS和CHINESE PHYS B,其中CHINESE PHYS有影响因子没有立即指数,CHINESE PHYS B同时有影响因子和立即指数。此时,老刊的影响因子通常会高一点,因为此时只计算早一年文章被引用的情况,被引用概率可能高一些(很不幸的是,CHINESE PHYS是下降的)。新刊的影响因子通常会低一点,因为此时计算的是晚一年文章被引用的情况,被引用的概率可能低一些。大家可以打开JCR看看这两个影响因子分别是怎么计算的。
JCR2010(2011年6月20日前后才会公布)中就只有CHINESE PHYS B了~
需要特别指出的是:更名后要及时通知相关人员(作者,同行?),否则引用时会写错的哦~~~比如引用的已经是CHINESE PHYS B的文章了,作者还是写成CHINESE PHYS了~~~这会造成混乱的,会影响影响因子的~~~
八卦一下,期刊名称还是简单易记比较好,学术期刊也是传媒业,呵呵,传媒人应该有品牌的意识,品牌管理忌讳晦涩难懂的名称的,JCR2009中国最牛的期刊也是:Cell Research、Nano Research,多好的名字~
