| dc.description | We present the estimates of the order $O(α^{4}_{s})$ QCD corrections to $R(s)$, $R_τ$ and to the deep-inelastic scattering sum rules, namely to the non-polarized and polarized Bjorken sum rules and to the Gross-Llewellyn Smith sum rule. The estimates are obtained in the $\overline{MS}$-scheme using the principle of minimal sensitivity and the effective charges approach. | |

Some misprints in the previous version corrected, thanks to F. Le Diberder for pointing them, PMS results in Tables 1-4 are affected. Changes do not affect main results | |
