 Moreover, determinables are typically multiply determined, and given that determinables and determinates are type- and perhaps also token-distinct, one can argue  (see §3.5)  that determinables are distinctively efficacious. If mental properties are determinables of physical realizers, these features are inherited: as causal non-competitors, overdetermination is avoided while accommodating multiple realizability, compatible with the distinctness and distinctive efficacy of mental properties. Similar considerations apply to other higher-level goings-on, in which case realization might be determination, more generally.
