ジャーナル・インパクト・ファクターが発表

ジャーナル・インパクト・ファクター(Journal Impact Factor)は、学術雑誌の影響力を測る指標で、対象年における引用回数を、対象年に先立つ 2 年間にそのジャーナルが掲載したソース項目の総数で割ることによって計算されます(インパクトファクターについて  Clarivate Analytics)。

The Impact Factor of journal J in the calendar year X is the number of citations received by J in X to any item published in J in (X-1) or (X-2), divided by the number of source items published in J in (X-1) or (X-2). (Measuring  a journal’s impact. ELSEVIER)

インパクトファクターが高いジャーナルに論文が通るかどうかで、研究者は一喜一憂しますが、インパクトファクターの動向が気がかりなのは、雑誌社にとっても同じです。ちなみに、研究分野や雑誌のスコープにより数字の出方がかなり異なるため、分野や性格の違う雑誌同士でインパクトファクターを比較して優劣を論じるのは無意味です。

 

2016年のインパクトファクターが、公表されました。その中から一部を紹介します(参照サイト: researchgate.net/post/New_Impact_factors_2017_for_Journals_are_released_nowbioxbio.com/ifCell Press Journal Metrics、個々のジャーナルサイトなど)
