title: Anisotropic scaling of magnetohydrodynamic turbulence

authors: Horbury, Timothy S.

subjects: mathematics

abstract: We present a quantitative estimate of the anisotropic power and scaling of magnetic field fluctuations in inertial range magnetohydrodynamic turbulence, using a novel wavelet technique applied to spacecraft measurements in the solar wind. We show for the first time that, when the local magnetic field direction is parallel to the flow, the spacecraft-frame spectrum has a spectral index near 2. This can be interpreted as the signature of a population of fluctuations in field-parallel wavenumbers with a k║-2 spectrum but is also consistent with the presence of a "critical balance" style turbulent cascade. We also find, in common with previous studies, that most of the power is contained in wavevectors at large angles to the local magnetic field and that this component of the turbulence has a spectral index of 5/3.

title: Sampling community discourses as a method for assessing "public opinion"

authors: Guerin, Bernard

subjects: racial prejudice

abstract: In working with the topics of racial discrimination and household energy reductions it is clear that just measuring attitudes is no longer sufficient. We need a fuller social context to understand what is said about these topics, as the same words can be used for many reasons. I am working with four new methods for "sampling community discourses" on topics such as racial prejudice, to replace or supplement the measurement of attitudes. The initial analysis is whether the talk functions to get someone to do something directly, to get someone to believe the 'facts', or whether the talk functions for the establishment or maintenance of social relationships. Many problems remain, especially the representativeness of the sampling and keeping as much of the context of the talk as possible.

title: E Toru Ngā Reo: A Case Study of a Spanish Language Programme in a Kura Kaupapa Māori

authors: Flavell, William

subjects: Kaupapa Maori Research

abstract: Learning Languages is a new area in the 2007 New Zealand Curriculum.  However there have not been many studies in this subject.  Kura Kaupapa Māori, established in 1985 in New Zealand with over 6,000 students currently attending, have English language programmes (Hill, 2010), however few, if any, studies of the teaching of other languages have been conducted.  The purpose of this study was to describe and evaluate an additional international language programme at a Kura Kaupapa Māori.

This qualitative case study describes the views of the Principal, five teachers, five students and three parents of a Kura Kaupapa Māori about an additional Spanish language programme. The primary means of gathering data was through individual semi-structured interviews.  Interviews were used to collect data in the areas of identifying the attitudes of the participants towards learning an additional international language, the perceived benefits, if any, of learning an additional international language and if there is a relationship between the learning of an  additional international language, and Kaupapa Māori.  The narrative data was transcribed, coded and categorised into four themes related to the research questions.  

 The success of this Spanish language programme can be understood in terms of several factors such as whānau support, programme leadership, quality teachers, international excursions and positive attitudes to foreign language learning.  

These findings will contribute to literature concerning additional language learning programmes, specifically those based in indigenous language immersion settings and they will also provide useful information and ideas which other Kura Kaupapa Māori can take advantage of when implementing additional international language learning programmes.
