I have distributed web links (on paper) to http://hannah-hannah-land.blogspot.com/search/label/Ashby as a way to find a draft of the written version of the paper I gave at the postgrad conference and will give at ANZHES next week. You can get to that draft at http://docs.google.com/Doc?id=dfqggshp_28f2npxpg6
Due to size restrictions in googledocs, the footnotes are here http://docs.google.com/Doc?docid=dfqggshp_32c3bwndd6&hl=en
I am still working on this paper (thus it is still a "draft"). Please feel free to email me comments.
