Hi Rich.  When I search my articles folder for <Kraemer>, I find several
articles, but not that one.  I was aware of it, because I'd noticed it when
looking at Christine Blasey's Google Scholar profile:

  https://scholar.google.ca/citations?user=J2T7HxgAAAAJ&hl=en

Re centering variables prior to regression analysis, I'm generally less
enthusiastic about it than I used to be.  Occasionally, it may be necessary
to deal with numerical problems that arise.  But generally, if one has
software that makes it easy to compute and plot marginal values of Y, those
tables and plots are far more useful than the table of coefficients is in
helping a reader understand the nature of the model.
