    • Citation data from Web of Science
    • Research Fields from Essential Science Indicators
    • Baseline data from Essential Science Indicators
  • 4. How do we compare numbers?
    • Scientist Z. Math has a publication from 1996 with 17 citations
    • Scientist M. Biology has a publication from 2003 with 24 citations
  • 5. Baseline mathematics
  • 6. Baseline Molecular Biology
  • 7. Example
    • Schoorl, J.M., Sonneveld, M.P.W., Veldkamp, A. ( 2000 ) Three-dimensional landscape process modelling: The effect of DEM resolution. Earth Surface Processes and Landforms , 25 (9): 1025-1034.
      • Time cited: 33 times
    • Earth Surface Processes and Landforms (look up in journals menu ESI)
      • Geosciences , ranked 60 th, 6.96 citations per article over past 10 years
    • Baseline data (from ESI)
      • Article from 2000 in Geosciences : Average: 13.08 citations, 10%: 31 citations, 1%: 99 citations
    • RI= 33 / 13.08 = 2.3

  • 9. Journal selection
  • 10. Where to publish
    • It is better to publish one paper in a quality journal than multiple papers in lesser journals. …………. Try to publish in journals that have high impact factors; chances are your paper will have high impact, too, if accepted.
    Bourne PE (2005) Ten Simple Rules for Getting Published . PLoS Comput Biol 1(5): e57 doi:10.1371/journal.pcbi.0010057 or at SciVee
  • 11. Journal selection
    • Quantitative tools
      • Journal citations reports
      • Journal information from Essential Science Indicators
      • ScimagoJR
  • 12. Journal Citation Reports (JCR)
    • Reports 3 measures
    • Impact factor
    • Immediacy Index
    • Cited half life
    Cited half-life 50% citations 50% citations 3 1 Immediacy index Window Impact Factor Window
  • 13. Impact factor
    • Performance measure for journals
      • “… it is also used for assessment of the quality of individual papers, scientists and departments. For the latter a scientific basis is lacking, as we will demonstrate in this contribution” (Opthof, 1997)
      • Opthof, T. (1997). Sense and nonsense about the impact factor. Cardiovascular Research 33 (1): 1-7. http:// dx.doi.org /10.1016/S0008-6363(96)00215-5
  • 14. 50 % of articles generate 90% of all cites Seglen, P. O. (1997). Why the impact factor of journals should not be used for evaluating research. BMJ 314 (7079): 497-502. http://bmj.bmjjournals.com/cgi/content/full/314/7079/497
