  We discuss the destruction of superconductivity in quasi-one-dimensional
systems due to the interplay between disorder and Coulomb repulsion. We argue
that to understand the behavior of the system one has to study both fermionic
and bosonic mechanisms of suppression of superconductivity. The former
describes reduction in the mean field critical temperature $T_c$, while the
latter refers to thermal and quantum fluctuations in the order parameter. A
change in parameters such as wire width and disorder strength significantly
affects both mechanisms.
