Joachim Schöpfel et al. have self-archived "Dissertations and Data."
Here's an excerpt:
The keynote provides an overview on the field of research data produced by PhD students, in the context of open science, open access to research results, e-Science and the handling of electronic theses and dissertations. The keynote includes recent empirical results and recommendations for good practice and further research. In particular, the paper is based on an assessment of 864 print and electronic dissertations in sciences, social sciences and humanities from the Universities of Lille (France) and Ljubljana (Slovenia), submitted between 1987 and 2015, and on a survey on data management with 270 scientists in social sciences and humanities of the University of Lille
