Disciplinary Coherence of Units

This presentation complements the article "How Journal Rankings Can Suppress Interdisciplinary Research" by Ismael Rafols et al. It explores the concept of disciplinary coherence as defined by the ratio of observed to expected cross-citations among various subject categories of research units. Visualizations help illustrate the citation dynamics between fields such as innovation studies and business management, highlighting the challenges posed by journal rankings in promoting or hindering interdisciplinary collaboration.

Presentation Transcript

  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 Rafols1, Loet Leydesdorff2,Alice O’Hare1, Paul Nightingale1 and Andy Stirling1 1 SPRU —Science and Technology Policy Research, University of Sussex, i.rafols@sussex.ac.uk 2 Amsterdam School of Communication Research (ASCoR), University of Amsterdam, 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 SCi to SCj (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 SCi to SCj 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
