abstract = "There is in the literature a number of papers addressing the
stochastic background of gravitational waves (GWs) generated by an
ensemble of astrophysical sources. The main ingredient in such
studies is the so called star formation rate density (SFRD), which
gives the density of stars formed per unit time. Some authors
argue, however, that there is, in the equation that determines the
amplitude of the stochastic background of GWs, an additional (1 +
z) term dividing the SFRD, which would account for the effect of
cosmic expansion onto the time variable. We argue here that the
inclusion of this additional term is wrong. In order to clarify
where the inclusion of the (1 + z) term is really necessary, we
briefly discuss the calculation of event rates in the study of
GRBs (gamma ray bursts) from cosmological origin. .",
