I am happy for you! However, this was not my question. I was just wondering
about the methodological legitimation of these categories. Can one use
something which one does not understand -- and nobody seems to understand
them -- as a basis for research and evaluation decisions? One knows that
outcomes of, for example, bibliometric assessments are heavily dependent on
this type of delineations.

Perhaps, I am the more old-fashioned one of the two of us. :-)

Best,  Loet
