and Cornell University which found found "that that the impact on time to degree in the humanities and social sciences is seen three to six years after the job market changes in various academic disciplines."

At this point, a good portion of the research study is self-directed and the candidate is left to manage the project, meet deadlines, and deal with impacts to the research. All the while, maintaining a semblance of work-life-school balance. As the dissertation defense looms closer, candidates will be looking ahead to completion of the program, graduation, and the job market.
