From the abstract:

We report on an exploratory study consisting of brief case studies in selected disciplines, examining what motivates researchers to work (or want to work) in an open manner with regard to their data, results and protocols, and whether advantages are delivered by working in this way. We review the policy background to open science, and literature on the benefits attributed to open data, considering how these relate to curation and to questions of who participates in science.
