Nadine Levin et al. have published "How Do Scientists Define Openness? Exploring the Relationship between Open Science Policies and Research Practice " in the Bulletin of Science, Technology & Society
Here's an excerpt:
This article documents how biomedical researchers in the United Kingdom understand and enact the idea of "openness." . . . This study is based on 22 in-depth interviews with U.K. researchers in systems biology, synthetic biology, and bioinformatics, which were conducted between September 2013 and February 2014. Through an analysis of the interview transcripts, we identify seven core themes that characterize researchers' understanding of openness in science and nine factors that shape the practice of openness in research.
