One little detail about my dissertation I've been working on is pseudonyms for the colleges I'm studying. It shouldn't be this difficult, but I had to reject any number of schema. Numbers or letters implied hierarchy among the three. Colors carry too many connotations. It's hard to find common last names that aren't in use already (Smith, Jones, Brown - all taken). First names don't sound dignified ("Fred College"). Many things were just too whimsical.
So I've finally settled on tree names. Common trees sound rather dignified, have positive associations, and can't be readily rank-ordered. There are a few schools with "Elm" or "Oak" in their names, so I'm excluding those. Pine College, Maple College, and Birch College - I think I'm set.
