Impact factor

 

Figure 1: Calculation for journal impact factor.
A= total cites in 1992
B= 1992 cites to articles published in 1990-91 (this is a subset of A)
C= number of articles published in 1990-91
D= B/C = 1992 impact factor
  • the journal impact factor, the ratio of the number of citations to the previous 2 years of the journal divided by the number of articles in those years — this is essentially the average number of recent citations per article

  • the journal immediacy index, the number of citations that year to articles published the same year,

  • the journal citing half life, the median age of the articles that were cited by the articles published in the journal that year,

  • the journal cited half life, the median age of the articles in the journal that were cited by other journals during the year

Where to find it? On the journal homepage, or here: ISI Web of Knowledge - Journal Citation Reports

H-index

Hirsch: A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each

Hirsch suggested that, for physicists, a value for h of about 10–12 might be a useful guideline for tenure decisions at major research universities. A value of about 18 could mean a full professorship, 15–20 could mean a fellowship in the American Physical Society, and 45 or higher could mean membership in the United States National Academy of Sciences.
