For your reading pleasure (torture)... This is my PhD in its entirety, just a couple of edit rounds from submission. For those who want the quick version read the abstract, chapter 1 and chapter 9. The detailed findings are chapters 4-8. If you like a lot of theory you can find it in chapter 2. All comments are welcome. http://cbe.anu.edu.au/tmp/PhD_Complete_v2.pdf This link may be temporary, if it doesn't work email me at firstname.lastname@example.org and I can send you a copy. Its too big to attach using the forum system.
