5. Where to publish?
A valued journal?
● Editorial board
● Acceptance rate
● Time to publication
● Journal circulation
● Visibility
● Journal performance
6. Journal performance measures (indicators)
Journal Citation Reports (JCR)
● a.o. standard Journal Impact Factor and 5-year
Impact Factor
Scopus Journal Analyzer (SJA)
● Scimago Journal Rank (SJR)
prestige metric based on the idea that ‘all
citations are not created equal’
● Source Normalized Impact per Paper (SNIP)
Measures contextual citation impact by
‘normalizing’ citation values

9. Bibliometric indicators: An example
Zee, F.P.v.d., G. Lettinga & J.A. Field (2001) Azo dye
decolourisation by anaerobic granular sludge.
Chemosphere 44:1169-1176.
● Citations from WoS: 94
Journal: Chemosphere
● Categorised by ESI in Environment/Ecology
Baseline data for Environment/Ecology.
● Article from 2001 in Environment/ecology:
● On average: 19.36 citations; top 10%: 44 citations; top1%: 141
citations
Relative Impact: 94 / 19.36 = 4.9
10. h-index
A scientist has index h
if h of his/her Np
papers have at least h
citations each, and the
other (Np − h) paper
have no more than h
citations each.
11. h-index
h-index tries to find a balance between productivity and
citation impact
Only published in 2005, has made a substantial impact
in the world of bibliometrics.
Applicable to authors, journals, research groups,
compounds, subjects etc…
But there are some serious doubts
Waltman, L. & N. J. van Eck (2011). The inconsistency of the h-index. Journal of the American Society for
Information Science and Technology: n/a-n/a http://dx.doi.org/10.1002/asi.21678

21. The impact factor Matthew effect
The journal in which papers are published have a
strong influence on their citation rates, as duplicate
papers published in high-impact journals obtain, on
average, twice as many citations as their identical
counterparts published in journals with lower
impact factors..
Larivière, V. and Y. Gingras (2010). The impact factor's Matthew Effect: A natural
experiment in bibliometrics. Journal of the American Society for Information Science
and Technology 61(2): 424-427. http://dx.doi.org/10.1002/asi.21232
22. Final word on journal selection
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.

25. Cooperation...
Teams increasingly dominate solo authors in the
production of knowledge. Research is increasingly done
in teams across nearly all fields.
Teams typically produce more frequently cited research
than individuals do, and this advantage has been
increasing over time.
Teams now also produce the exceptionally high-impact
research, even where that distinction was once the
domain of solo authors.

production of knowledge. Science 316(5827): 1036-1039.

26. Networking is important!
Start early, make use of social networking
tools
Facebook
LinkedIn
Social networks for scientists
Academics.edu, Researchgate, Nature networks,
Labmeeting
30. Self citations
The model [...] implies that external citations are
enhanced by self-citations, so that we have the “chain
reaction:” Larger size leads to more self-citations,
which lead to more external citations.

mechanism in the science system. Journal of the American Society for
Information Science and Technology 59(10): 1631-1643.

31. More on references
Articles that cite more references are in turn cited
more themselves

Ortega Hypothesis. PLoS ONE 5(10): e13327 DOI: http://dx.doi.org/10.1371/journal.pone.0013327.
32. Publish your data!
Henneken et al. (2011) "articles with links to data result
in higher citation rates than articles without such links"
http://arxiv.org/abs/1111.3618
Piwowar et al. (2007) "Sharing detailed research data is
associated with increased citation rate

35. e-Theses are the mainstay of OA
publications for Wageningen UR
Theses : 200 theses * 4 articles ~ 800
preprints/year
Productivity Wageningen UR: 2400 peer reviewed
articles / year
This accounts for: 33% of the output
36. Make your publications OA available
Be aware of your copyrights when publishing
Golden Road
PloS Journals, BMC, etc
Green Road
Self archived copies (final author’s version)
Wageningen Yield, RePec, ArXiv etc.
Open Choice
Hybrid system, author pays and library pays
Springer journals are a favourable exception

38. Is there a citation advantage for OA?
Evidence is not entirely conclusive, but mounting
van Raan has started to self archive his preprints
OA is important for developing countries
