Hi Garry,

I read through this article quickly when I was a bit pushed for time and will get back to it properly as soon as I can. There is quite a lot to take in. However, I was wondering whether this is a thesis paper, part of a book or a perhaps a substantial article for a journal. I suppose it doesn't really matter but I would like to be able to place it in some sort of context as to its main purpose.

Thanks
Sue
