Herkko Hietanen, project lead for CC Finland, has made his 320 page dissertation available online under the CC BY-NC-ND license, titled The Pursuit of Efficient Copyright Licensing — How Some Rights Reserved Attempts to Solve the Problems of All Rights Reserved:

The dissertation contributes to the existing literature in several ways. There is a wide range of prior research on open source licensing. However, there is an urgent need for an extensive study of the Creative Commons licensing and its actual and potential impact on the creative ecosystem.

Indeed! Congratulations to Herkko, and may his book inspire more such research.
