    "abstract": "Recent calculations of charge symmetry violation(CSV) in the valence quark\ndistributions of the nucleon have revealed that the dominant symmetry breaking\ncontribution comes from the mass associated with the spectator quark\nsystem.Assuming that the change in the spectator mass can be treated\nperturbatively, we derive a model independent expression for the shift in the\nparton distributions of the nucleon. This result is used to derive a relation\nbetween the charge and flavor asymmetric contributions to the valence quark\ndistributions in the proton, and to calculate CSV contributions to the nucleon\nsea. The CSV contribution to the Gottfried sum rule is also estimated, and\nfound to be small.",
