Heavy quark (b b-bar and c c-bar) forward-backward asymmetries measured at LEP are presented along with polarized forward-backward and left-right asymmetries measured at SLD. The results are compared, and the combined averages are used to evaluate the Standard Model parameters.8 Pages, 5 eps files, Presented at the International Europhysics Conference on High Energy Physics, August 1997, Jerusalem, IsraelHigh Energy Physics - Experimenttext
