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
