I made a foolish mistake in class today by trying to cover both non-strict and strict partial orders with a single definition. Notwithstanding anything that I said, you should think of a partial order (e.g. subset-of, ≤, divides, prefix-of) as as relation that is reflexive, antisymmetric, and transitive, and a strict partial order (e.g. proper-subset-of, <) as a relation that is irreflexive, antisymmetric, and transitive. Trying to mix these two concepts together just leads to pain, since we generally don't care how elements of a poset relate to themselves, and it's easier to just pick reflexivity or irreflexivity. I apologize for not being more careful about this. —Jim.
