We present here a simple qualitative model that interpolates between the high- and low-temperature properties of quasi-one-dimensional conductors. At high temperatures we argue that transport is governed by inelastic scattering while at low temperatures the conductance decays exponentially with the electron dephasing length. The crossover between these regimes occurs at the temperature at which the elastic and inelastic scattering times become equal. This model is shown to be in quantitative agreement with the organic conductor (Formula presented) Within this model, we also show that on the insulating side, the positive magnetoresistance of the form (Formula presented) observed in (Formula presented) and other quasi-one-dimensional conductors can be explained by the role spin-flip scattering plays in the electron dephasing rate.
