Abstract
The crossover from back-and-forth jumps between structural minima to the no-return jumps of the viscous flow is modeled in terms of an ensemble of double-well potentials with a finite decay probability. The ensemble is characterized by the Kohlrausch-exponent of the time dependence of the response at short times. The model is applied to shear and dielectric data from the literature.

Second version changed according to advice of Referees: Rewritten to Regular Article. New data included, in particular monoalcohol data, which argue for a common crossover to viscous processes in dielectrics and shear
