Sabine Elisabeth Puskas has self-archived her Master's dissertation, "The Effects of Open Access Mandates on Institutional Repositories in the UK and Germany," in the Loughborough University Institutional Repository.
Here's an excerpt:
There is evidence that institutional mandates do have effects on institutional repositories in different ways, e.g. on content deposited and service provision. The effects vary according to the characteristics of repositories and the approach taken by institutions. The research results also indicate that the experiences of institutions with a mandate and the expectations of institutions without one are almost identical across both the UK and Germany, although the developmental context of institutional repositories and institutional mandates in these two countries are very different.
