Previously published analysis on thrust, jet broadening, jet mass and C parameter are substantially refined and updated; differential two-jet rates treated as event shapes are presented for the first time. The Q dependence of the mean values is fit to second order calculations of perturbative QCD applying power law corrections proportional to 1/Q^p to account for hadronization effects. The concept of these power corrections is tested by a systematic investigation in terms of a non-perturbative parameter \bar{alpha}_{p-1} and the strong coupling constant.Ph.D. thesis, RWTH Aachen 12/1998, 140 pages, 22 tables, 51 figures (eps), figures 2.1, 2.2 and 2.4 as low resolution version onlyHigh Energy Physics - Phenomenologytext
