Here's an excerpt:
This [Ph.D] thesis investigated the factors that contribute to the cultural shift towards open science and data sharing in health and medical research, with a focus on the role health and medical journals play. The findings of this research demonstrate that journal data sharing policies are not effective and that journals do not currently provide incentives for sharing. This study contributed to the movement towards more reproducible research by providing empirical evidence for the strengthening of journal data sharing policies and the adoption of an incentive for open research.
