Cameron Neylon has published "Building a Culture of Data Sharing: Policy Design and Implementation for Research Data Management in Development Research" in Research Ideas and Outcomes.
Here's an excerpt:
The project had two core findings. First that the shift from an aim of changing behaviour, to changing culture, has both subtle and profound implications for policy design and implementation. A particular finding is that the single point of contact that many data management and sharing policies create where a Data Management Plan is required at grant submission but then not further utilised is at best neutral and likely counter productive in supporting change in researcher culture.
