Abstract
Studies of event shape observables at PETRA and LEP energies are presented. Previously published determinations of the strong coupling constant \alpha_s at \sqrt{s} = 35 and 44 GeV are complemented using new resummed QCD calculations for the C parameter and improved calculations for the jet broadening variables B_T and B_W which recently became available. Furthermore, recently predicted power corrections to the differential distributions of these observables are investigated. In this study, e^+e^- data between \sqrt{s} = 35 and 183 GeV are considered.
