My 2012 M.A. thesis, Franz Marc as an Ethologist, is now part of the online collection of the open-access Social Science Research Network (SSRN). You can download it or look at the abstract here.
UPDATE: I just can’t with Elsevier’s involvement with SSRN. In addition to Elsevier being generally evil, not supporting open access, and ruining the Pergamon imprint, more than a year after acquiring SSRN, there is still no discrete art history rubric, or way for authors to track who is looking at their work. But mainly Elsevier is garbage.
