  We use inelastic neutron scattering to study magnetic excitations of
Sc$_{1-x}$U$_{x}$Pd$_3$ for U concentrations ($x=0.25$, 0.35) near the spin
glass quantum critical point (QCP). The excitations are spatially incoherent,
broad in energy ($E=\hbar\omega$), and follow $\omega/T$ scaling at all wave
vectors investigated. Since similar $\omega/T$ scaling has been observed for
UCu$_{5-x}$Pd$_x$ and CeCu$_{6-x}$Au$_{x}$ near the antiferromagnetic (AF) QCP,
we argue that the observed non Fermi liquid (NFL) behavior in these
$f$-electron materials arises from the critical phenomena near a T=0 K phase
transition, irrespective of the nature of the transition.
