title: Exact solutions for steady-state, planar, magnetic reconnection in an incompressible viscous plasma

authors: Fabling, R.B.

subjects: mathematics

abstract: The exact planar reconnection analysis of Craig and Henton [Astrophys. J. 450, 280 (1995)] is extended to include the finite viscosity of the fluid and the presence of nonplanar components in the magnetic and velocity fields. It is shown that fast reconnection can be achieved for sufficiently small values of the kinematic viscosity. In particular, the dissipation rate is sustained by the strong amplification of planar magnetic field components advected toward the neutral point. By contrast, nonplanar field components are advected without amplification and so dissipate energy at the slow Sweet–Parker rate.

title: Laying the tracks: Investigating the potential benefits for autistic children of a model railway initiative

authors: Gedye, Jacob

abstract: This study described a model railway programme in terms of its benefits for autistic children and their families/communities. A non-experimental mixed-method design was conducted, in which an observation schedule was designed to determine whether behaviours which are associated with language development were facilitated by the programme. Interviews with parents/caregivers were conducted to collect qualitative data about the programme, to better understand how it is perceived by visitors and what draws them to attend. Individual case studies with children and their parents/caregivers were done to build a clearer picture of what can be seen at an individual level. Finally, a focus group was arranged with members of the railway modeller’s club to find out their point of view and broaden the qualitative scope of the data. Findings suggest potential utility in this programme for autistic children and future research implications are discussed.

title: Bicultural perspectives on Māori legal research

authors: Mackinnon, Jacquelin

subjects: Māori

abstract: Increasingly, legal research projects undertaken at law school or in practice will involve Māori custom law and/or tikanga Māori.' The role of both Māori custom law and tikanga Māori is most evident in the work of the Māori Land Court in the interpretation and application of legislation relating to Māori land. Increasingly, general statutes incorporate Māori principles and values, such as those to be found in the Resource Management Act 1991, or make explicit reference to the principles of the Treaty of Waitangi. The statutory interpretation function of the Courts in relation to these, and less obvious examples, requires knowledge of tikanga Māori and/or Māori custom law. For any analysis of the work of the Courts or of the legislature, knowledge of tikanga Māori and/or custom law is required. Both Māori custom law and tikanga Māori are preserved by and accessed through the oral tradition. In addition to its role in the Courts and in relation to legislation, the most significant role played by the oral tradition is in the work of the Waitangi Tribunal. The oral tradition also plays an increasingly important part in other areas requiring research. What follows is an introduction to the oral tradition and its role in the legal system of Aotearoa/New Zealand. An understanding of the oral tradition is essential to the construction of a research path that is both ethical and effective.
