Abstract: Following from recent developments by Hubalek and Kyprianou, the objective ofthis paper is to provide further methods for constructing new families of scalefunctions for spectrally negative L\-evy processes which are completelyexplicit. This is the result of an observation in the aforementioned paperwhich permits feeding the theory of Bernstein functions directly into theWiener-Hopf factorization for spectrally negative L\-evy processes. Many new,concrete examples of scale functions are offered although the methodology inprinciple delivers still more explicit examples than those listed.
