Looking for published ruby on rails studies

Hello all,

I was wondering if anyone would be willing to help me with a project
I'm working on for my graduate studies in software engineering. I'm
currently working on a project involving Ruby on Rails and am
*currently* looking for any published research that highlight the
benefits (e.g. financial gains in time, cost, and quality, etc.) for
companies to move towards using RoR as their language/framework for
"enterprise" web application development. I am mostly a Java developer
(also groovy/grails, php, python, and more) new to RoR and am looking
to be a convert. As such, I'm not very familiar with all the available
resources of information and thought this forum would be a good place
to start.

Any help is greatly appreciated.

Thank you,
Aaron
