      abstract     = {Quark line disconnected matrix elements of an operator,
                      such as the axial current, are difficult to compute on the
                      lattice. The standard method uses a stochastic estimator of
                      the operator, which is generally very noisy. We discuss and
                      develop further our alternative approach using the
                      Feynman-Hellmann theorem which involves only evaluating
                      two-point correlation functions. This is applied to
                      computing the contribution of the quark spin to the nucleon
                      and in particular for the strange quark. In this process we
                      also pay particular attention to the development of an SU(3)
                      flavour breaking expansion for singlet operators.},
