I am happy to announce (I just received official work today) that my
thesis will be published this June with Garland Press (Outstanding
Dissertations in Linguistics Series). I have no idea how much it will
cost (nor what they charge for current titles in this series, though I
suspect it will be comparable).
If you absolutely need something now, it's available through
University of Michigan ($30+), or I could try to make a copy (I sent
the last away...). I think copying is $12 or so ... Or, I have an
article that basically summarizes the Greek chapter, but without the
lexical aspect (aka 'Aktionsart') discussion.
