I'm a big fan of Peter Leithart's blog, although I'm not always certain of what he is saying, and I'm still in disbelief that anybody can read the sheer magntitude that he does.
One thing Leithart does fairly often is to subject various parts of Scripture to structural analyses. He has written a fair amount of Ruth, but from what I've seen hasn't posted anything on chiasms in Ruth at his website. So, without further ado, here is my first attempt at posting on the chiastic structure of anything:
A' Father and mother leave Israel, and sons find wives in Moab, land of plenty
B' Ruth follows Noami, vowing to adopt her gods, her land, and her people
C' Ruth adopts Israel, the land of plenty, redemption, kinship, and romance
B' Ruth seeks out (follows) Boaz, is adopted into the lineage of Christ through a marriage vow
A' Mother regains son (in-law) and daughter-in-law regains husband in Israel, land of plenty
Mine is desperately simple, but a far more comprehensive look at Ruth's chiastic structure can be viewed at San Diego First Assembly's website: Chiastic Structure of the Book of Ruth
If you're inclined to attempt reading Leithart, I'd recommend you begin with A House for My Name: A Survey of the Old Testament.
