Is there a list somewhere of what modifications each difficulty level makes to the game?

There seems to be a hint in the game. In the upper right corner of your empire screen there is a list of all your empire buffs. The difficulty seems at least to modify disapproval due to empire size.

I haven't seen any list describing difficulty settings' effects, yet.
