This is a doctoral thesis from a few years back by a student at the University of Queensland, one Hee Sheng Shi Fashu Sim, listed here. Apparently, it is only accessible to UQ faculty and students. I have seen online where some people shared the file, but that was in a discussion thread quite a few years ago, so I don’t think I could contact them.
Knowing that many here are in Australia, I thought someone might perhaps be affiliated with the university, be familiar with the author, or know how to access the files. If this would be in any way unethical or illegal, please feel free to completely disregard this post. (I am not really well versed in all the intricacies of the restriction of academic knowledge.) This is just the only point-for-point comparative of the Vibhaṅga and Dharmaskandha I’ve seen.
Thanks in advanced.
