Ah, just saw your amendment Thomas ... actually I am looking for a general term..
If you know of US specific equivalents just spill them out... as much as one thing may be less relevant than another , who knows.
This is as much for my own purposes but also to help others - there is no entry for the word in the glossary yet. Also I believe there may be several words for such an institution.
You or anyone who is interested may have a look at this one here:
