In conclusion

ETE very productive group

Average citation impact

But what does it mean?

Citation data from Web of Science

Research Fields from Essential Science Indicators

Baseline data from Essential Science Indicators

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

Baseline mathematics

Baseline Molecular Biology

Example

Zee, F.P.v.d., G. Lettinga, and J.A. Field (2001) Azo dye decolourisation by anaerobic granular sludge. Chemosphere 44:1169-1176.

Time cited: 65 times

Chemosphere (look up in journals menu ESI)

Environment/Ecology , 7.95 citations per article

Baseline data (from ESI)

Article from 2001 in Environment/ecology: Average: 11.62 citations, 10%: 27 citations, 1%: 82 citations

RI= 65 / 11.62 = 5.6

Journal selection

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.

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)

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
