Data Sharing by Scientists: Practices and Perceptions

This link was tweeted by one of my supervisors: http://www.plosone.org/article/info:doi/10.1371/journal.pone.0021101. It's published in PLoS ONE - one of my favorite journals! 

Here's a brief bit from the background:
Scientific research in the 21st century is more data intensive and collaborative than in the past. It is important to study the data practices of researchers – data accessibility, discovery, re-use, preservation and, particularly, data sharing. Data sharing is a valuable part of the scientific method allowing for verification of results and extending research from prior results.
