I am defending my dissertation to my committee tomorrow. I have tried to make it as open as possible. One way I have done this is writing and then saving the manuscript (and code for the analysis) in a public place (here).
That repository is on GitHub and includes a PDF of my dissertation and the R Markdown files used to generate it. It also includes the PowerPoint presentation for tomorrow’s defense.
This is in fact a “sort of” open dissertation. That is because there is a lot more that could be shared (like the data!) that isn’t easy to share or isn’t shared, at least not yet.
