Using results from previous work on a spin-polaron model of high-{ital T}{sub {ital c}} superconductivity, together with a hole-filling mechanism, excellent agreement with experimental data for {ital T}{sub {ital c}} in Y-Ba-Cu-O and Pr-Ba-Cu-O alloys and layered structures is obtained without introducing either pair breaking by the Pr ions or pairing interactions between unit cells.
