title: Linear transport of solar wind fluctuations

authors: Oughton, Sean

subjects: linear transport

abstract: Numerical solutions for the linear transport of solar wind fluctuations are presented. The model used takes into account the effects of advection, expansion, and wave propagation, as well as the recently illuminated effects of (non-WKB) “mixing” terms. The radial evolution of the fluctuating kinetic and magnetic energies and of the cross helicity is computed, and it is demonstrated that in appropriate limits the solutions converge to the WKB forms. In more general cases, however, where the fluctuations consist of a superposition of various types of turbulence, mixing leads to solutions which differ substantially from those predicted by WKB theory. The degree of mixing shows considerable dependence on the nature of the turbulence, giving rise to varying levels, at 1 ∼ AU, of the ratio of “inward” and “outward” fluctuation energies and the ratio of kinetic and magnetic fluctuation energies. The transport properties described here may provide a partial explanation for the observed decrease of cross helicity with increasing heliocentric distance in the solar wind.

title: Deictic Framing Performance Fails to Generalize to Other Perspective-Taking Tasks

authors: Taylor, Tokiko

abstract: The behavioral processes underlying perspective taking have not been studied extensively. One approach to understanding and enhancing perspective taking, deictic framing, has been proposed. Proponents of this approach have suggested that deictic framing is a core property of perspective taking. A training protocol based on deictic framing has been developed and tested, but researchers generally evaluate the effectiveness of the protocol using tasks that have a similar format to the training protocol. Little research has examined the protocol’s effectiveness for improving performance in different perspective-taking tasks. We investigated generalization of the performance of three groups of university students trained with a deictic-framing protocol (or not) and tested with two other perspective-taking tasks: a visuospatial perspective taking using a cupboard containing a range of objects and a version of the implicit relational assessment procedure specifically designed to measure perspective taking. The first group was trained with the original verbal protocol with deictic expressions; the second group with the same protocol involving nondeictic words; and the third group was merely exposed to deictic expressions as a control condition. The results suggested that deictic framing is not fundamental to perspective taking, as the performance of the two experimental groups was not significantly different from the control group’s performance. Identification of specific stimulus functions involved in successful perspective taking and how those functions can be established should be addressed in future research.

title: The waters of the Maori: Maori law and state law

authors: Durie, Edward Taihākurei

abstract: This paper is for filing in the Waitangi Tribunal in relation to a claim that existing laws do not adequately accommodate the Māori proprietary interest in natural, water resources. The claim was initiated by the New Zealand Māori Council in association with ten tribal groups. It was later accompanied by 166 other Māori groups, whom the Tribunal joined as interested parties.
