1 Disciplinary Coherence of Units These slides complement the article How journal rankings can suppress interdisciplinary research: A comparison between innovation studies and business & management Available at: www.interdisciplinaryscience.net http://www.sussex.ac.uk/Users/ir28/IDR/Rafols2011-Rankings&IDR.pdf Ismael Rafols 1, Loet Leydesdorff 2, Alice O’Hare 1, Paul Nightingale 1 and Andy Stirling 1 1 SPRU —Science and Technology Policy Research, University of Sussex, i.rafols@sussex.ac.uki.rafols@sussex.ac.uk 2 Amsterdam School of Communication Research (ASCoR), University of Amsterdam, loet@leydesdorff.net loet@leydesdorff.net

2 Coherence Defined as the Ratio of Mean Observed Distance of Cross-Citations over Mean Expected Distance of Cross-Citations

3 Visualisation of Observed and Expected cross-citations between Subject Categories (SCs) of unit’s publications Notes: Node size = Sum of citations from each Subject Category Blue links = Expected % of cross-citations from SC i to SC j (given the total number of references from SCi and given the average citation flows from SCi to SCj in the Web of Science) Orange links = Observed % of cross-citations from SC i to SC j Only links representing more than 0.2% citations are shown Green Lines = Observed / Expected Only links with Observed/Expected>5, and Observed>0.2% are shown

4 Edinburgh ISSTI

5 Expected cross-citations Line Size= # citations Node Size = # citations from each SC

6 Observed cross-citations Line Size= # citations Node Size = # citations from each SC

7 Observed/Expected citations Line Size= Logscale of Observed/Expected citations Node Size = # citations from each SC
