      abstract     = {The strong coupling constant αs is determined from
                      inclusive jet and dijet cross sections in neutral-current
                      deep-inelastic ep scattering (DIS) measured at HERA by the
                      H1 collaboration using next-to-next-to-leading order (NNLO)
                      QCD predictions. The dependence of the NNLO predictions and
                      of the resulting value of αs(mZ) at the Z-boson mass mZ are
                      studied as a function of the choice of the renormalisation
                      and factorisation scales. Using inclusive jet and dijet data
                      together, the strong coupling constant is determined to be
                      αs(mZ)=0.1157(20)exp(29)th. Complementary, αs(mZ) is
                      determined together with parton distribution functions of
                      the proton (PDFs) from jet and inclusive DIS data measured
                      by the H1 experiment. The value αs(mZ)=0.1142(28)tot
                      obtained is consistent with the determination from jet data
                      alone. The impact of the jet data on the PDFs is studied.
                      The running of the strong coupling is tested at different
                      values of the renormalisation scale and the results are
                      found to be in agreement with expectations.},
