thanks Bewildered and Methodical
I'm off on hols for a couple of weeks this weekend. Supervisor has said not to think about any of it on holiday, but of course I will! I intend to take one of the key texts and reread it, in case I'm just missing something. It's a good idea to look at the thesis in the area, and I will on return - I did at the beginning but that was a while ago. One of the problems I think is that I think I don't sound right - academically - sometimes, if that makes sense. So rereading the theses would help. I come from a practice background so am not a born and bred academic as such, and I think I struggle at times because of that. Thanks for your help. If anyone else has anything to add I would be grateful - but probably won't be able to respond until I return, hopefully refreshed, from holidays. Bye for now :-)
