  We perform a study of infinite hadronic matter, finite nuclei and hypernuclei
with an improved method of calculating the effective baryon mass. A detailed
study of the predictions of the model is made in comparison with the available
data and the level of agreement is generally very good. Comparison with an
earlier treatment shows relatively minor differences at or below normal nuclear
matter density, while at high density the improved calculation is quite
different. In particular, we find no phase transition corresponding to chiral
symmetry restoration in high density nuclear matter.
