Good luck on your dissertation. You might want to consider a small edit on your title, to include something like "input requested", or some such thing...it might just catch more people's attention. (Unfortunately, I am completely ignorant on this topic, so no help, but I do recall conversations around here about Hartz...). Again...good luck on your writing!
