At the risk of labouring the point here’s another critque of the Gubitosi et al, paper I posted about a couple of days ago…
[Ewan Cameron pointed this paper to me and blogged about his impressions a few weeks ago. And then Peter Coles wrote a (properly) critical blog entry yesterday. Here are my quick impressions, as an add-on.]
