  Five-dimensional models where the bulk is a slice of AdS have the virtue of
solving the hierarchy problem. The electroweak scale is generated by a ``warp''
factor of the induced metric on the brane where the standard model fields live.
However, it is not necessary to confine the standard model fields on the brane
and we analyze the possibility of having the fields actually living in the
slice of AdS. Specifically, we study the behaviour of fermions, gauge bosons
and scalars in this geometry and their implications on electroweak physics.
These scenarios can provide an explanation of the fermion mass hierarchy by
warp factors. We also consider the case of supersymmetry in the bulk, and
analyze the conditions on the mass spectrum. Finally, a model is proposed where
the warp factor generates a small (TeV) supersymmetry-breaking scale, with the
gauge interactions mediating the breaking to the scalar sector.
