    "abstract": "Parity violating (PV) contributions due to interference between $\\gamma$ and\n$Z^0$ exchange are calculated for pion electroproduction off the nucleon. A\nphenomenological model with effective Lagrangians is used to determine the\nresulting asymmetry for the energy region between threshold and $\\Delta(1232)$\nresonance. The $\\Delta$ resonance is treated as a Rarita-Schwinger field with\nphenomenological $N \\Delta$ transition currents. The background contributions\nare given by the usual Born terms using the pseudovector $\\pi N$ Lagrangian.\nNumerical results for the asymmetry are presented.",
