  Data from e+e-annihilation into hadrons collected by the JADE experiment at
centre-of-mass energies between 14 GeV and 44 GeV were used to study moments of
event shape distributions and the four-jet rate as a function of the Durham
algorithm's resolution parameter y_cut. The data were compared to a QCD NLO
order calculations and including NLLA resummation in the case of the four-jet
rate. The strong coupling measured from the moments was
alpha_s(M_Z)=0.1286+-0.0007(stat)+-0.0011(exp)+-0.0022(had)+-0.0068(theo) and
from the four-jet rate was
alpha_s(M_Z)=0.1169+-0.0004(stat)+-0.0012(exp)+-0.0021(had)+-0.0007(theo) both
in agreement with the world average.
