preprint description
I show the quasi-truth of a sentence in a partial structure to be equivalent to the truth of a specific Ramsey sentence in a structure that corresponds naturally to the partial structure. Hence quasi-truth, the core notion of the partial structures approach, can be captured in the terms of the received view on scientific theories as developed by Carnap and Hempel. I further show that a mapping is a partial homomorphism/isomorphism between two partial structures if and only if it is a homomorphism/isomorphism between their corresponding structures. It is a corollary that the partial structures approach can be expressed in first or second order model theory.
