    "abstract": "We present a model description of the nucleon valence structure function\napplicable over the entire region of the Bjorken variable x, and above moderate\nvalues of Q**2 (\u003e 1 GeV**2). We stress the importance of describing the\ncomplete spectrum of intermediate states which are spectator to the\ndeep-inelastic collision. At a scale of 1 GeV**2 the relevant degrees of\nfreedom are constituent quarks and pions. The large-x region is then described\nin terms of scattering from constituent quarks in the nucleon, while the\ndressing of constituent quarks by pions plays an important role at intermediate\nx values. The correct small-x behavior, which is necessary for the proper\nnormalization of the valence distributions, is guaranteed by modeling the\nasymptotic spectator mass spectrum according to Regge phenomenology.",
