Instanton Contribution to the Pion Electro-Magnetic Formfactor at Q^2 > 1 GeV^2

We study the effects of instantons on the charged pion electro-magnetic formfactor at intermediate momenta. In the Single Instanton Approximation (SIA), we predict the pion formfactor in the kinematic region Q^2=2-15 GeV^2. By developing the calculation in a mixed time-momentum representation, it is possible to maximally reduce the model dependence and to calculate the formfactor directly. We find the intriguing result that the SIA calculation coincides with the vector dominance monopole form, up to surprisingly high momentum transfer Q^2~10 GeV^2. This suggests that vector dominance for the pion holds beyond low energy nuclear physics.Comment: 8 pages, 5 figures, minor revision

Counselling work in normal general practice: An analysis of Australian consultations.

As counselling is potentially an area of overlap between the functions of medical practitioners and of clinical health psychologists, it is important to know exactly what counselling encompasses in primary health care. A set of 68 counselling consultations were identified from collected transcripts of normal general practice work; seven representative examples are described and analysed in this article. The major purpose of three consultations was for the general practitioner (GP) to help the patient with psychological illness or behaviour disorder, and the question of most interest was how the parties negotiated this topic and how the GPs provided help. In four other consultations the major purpose was for the GP to answer the patient's questions. The results have implications for the delivery of primary health care and the work satisfaction of GPs, as well as for the collaborative relationships which may develop between GPs and clinical health psychologists
