Abstract
Recently Berman and Gomide have presented cosmological models with a c onstant deceleration parameter in general relativity without assuming a specific equation of state. It is shown that these models are equiva lent to those with bulk viscosity. Some general remarks are made on th e former models, including implications for violations of causality.
