I wish I had been more general with question 6c when searching for literature. I was more general with what I was searching for in this question, so found it easier to find a lot of really good and influential information. Where as because I was trying to be more specific with what I was looking for in question 6c I found it harder to find anything of any value.
Here is a link to my Delicious page, I am not very familiar with this website so I hope that I have posted my work in the correct place!!
Please let me know what you think!
