Re: Future UK RAEs to be Metrics-Based

Well, I'm all for empirically-based views in these matters. So, if
Openheim or others have actually soundly based studies showing what
Stevan and Openheim claim, then that's to be noted. I'll have to see
the stuff when it's published. In the meanwhile, a couple of further
questions:
--Pardon me for being out of touch, perhaps, but more precisely what is
being measured? What does journal "citation counts" refer to?
Citation of journal articles? Or citation of various things in journal
articles (and why privilege this medium?)? Or . . . what?
--What does "correlation" between RAE results and "citation counts"
actually comprise?

Let me lay out further reasons for some skepticism. In my own field
(biblical studies/theology), I'd say most senior-level scholars
actually publish very infrequently in refereed journals. We do perhaps
more in earlier years, but as we get to senior levels we tend (a) to
get requests for papers for multi-author volumes, and (b) we devote
ourselves to projects that best issue in book-length publications. So,
if my own productivity and impact were assessed by how many journal
articles I've published in the last five years, I'd look poor (even
though . . . well, let's say that I rather suspect that wouldn't be the
way I'm perceived by peers in the field).
Or is the metric to comprise how many times I'm *cited* in journals?
If so, is there some proven correlation between a scholar's impact or
significance of publications in the field and how many times he happens
to be cited in this one genre of publication? I'm just a bit
suspicious of the assumptions, which I still suspect are drawn (all
quite innocently, but naively) from disciplines in which journal
publication is much more the main and significant venue for scholarly
publication.
And, as we all know, "empirical" studies depend entirely on the
assumptions that lie at their base. So their value is heavily framed
by the validity and adequacy of the governing assumptions. No
accusations, just concerns.
