Thanks so much for your response Peter. The 'alternative' subcultures I have been most interested are goths, emos, skaters, fans of heavy metal, etc. However, I have also been involved in looking at homophobic and transphobic bullying, and my partner has researched domestic violence, so your own research is of real interest to me. If there's any papers you could send me, I'd be glad to have them. In the mean time, good luck with the development of your own model!
