    Notes: In this paper we clarify and generalize previous work by Moser and Belbruno concerning the link between the motions in the classical Kepler problem and geodesic motion on spaces of constant curvature. Both problems can be formulated as Hamiltonian systems and the phase flow in each system is characterized by the value of the corresponding Hamiltonian and one other parameter (the mass parameter in the Kepler problem and the curvature parameter in the geodesic motion problem). Using a canonical transformation the Hamiltonian vector field for the geodesic motion problem is transformed into one which is proportional to that for the Kepler problem. Within this framework the energy of the Kepler problem is equal to (minus) the curvature parameter of the constant curvature space and the mass parameter is given by the value of the Hamiltonian for the geodesic motion problem. We work with the corresponding family of evolution spaces and present a unified treatment which is valid for all values of energy continuously. As a result, there is a correspondence between the constants of motion for both systems and the Runge–Lenz vector in the Kepler problem arises in a natural way from the isometries of a space of constant curvature. In addition, the canonical nature of the transformation guarantees that the Poisson bracket Lie algebra of constants of motion for the classical Kepler problem is identical to that associated with geodesic motion on spaces of constant curvature. © 2000 American Institute of Physics.

    Notes: Intellectual or cognitive, as contrasted with social and political, aspects of the disparities between markets and education are discussed. McMurtry's argument is reviewed. Two engagements of the mind, paying attention and making distinctions, are elaborated, and items in the market place which undermine them are indicated. Acton's pro-market argument is acknowledged. The defence of advertising that it does not violate autonomy is contested, and it is argued that advertising contravenes both autonomy of action and autonomy of the mind. Marketing to children is further criticised for generating an escapist displacement from reality and humanity

    Notes: Although few organizations would claim to have sophisticated and well integrated performance management programs up and running, during the last two years the concept of performance management has undergone a major transition. Up until the late 1990s, performance management as a concept was being nurtured in business schools and was predominantly concerned with the balanced scorecard. Other than for a few best of breed vendors, it was not something that the software industry got too involved with, as implementing wall-to-wall ERP and CRM solutions was far more lucrative. However, things have changed. Performance management has leapt out of its pram and started to scream around the nursery. Just like any toddler, it is making a lot of noise and at times can be very difficult to comprehend. Exactly how, when and in what order events happened is difficult to pin down, but its transformation is certainly manifest. This article discusses the rapid evolution of performance management; the competitive and regulatory pressures that are providing momentum to performance management and concludes by examining how companies are merging individual performance management methodologies into integrated solutions.
