title: Exploring the ‘how’ and ‘why’ of value orientations in Physical Education teacher education

authors: Gillespie, Lorna B.

subjects: Physical Education teacher education

abstract: This paper focuses on the significance of curriculum value orientations for curriculum implementation and, therefore, for teacher education. The paper draws on data arising from research undertaken with six Health and Physical Education teachers in Aotearoa New Zealand to explore issues pertinent to Physical Education teacher education (PETE). Selected findings from the study are presented and critically engaged with from a teacher education viewpoint to specifically address (i) considerations relating to students’ value orientations that teacher educators need to be cognisant of, and (ii) issues arising for teacher educators seeking to engage with value orientations in undergraduate and/or post-graduate PETE programmes. The paper foregrounds the highly personal nature of value orientations in considering their significance in teacher education programmes and is written from the position of the author as a teacher educator committed to raising student teachers’ awareness of value orientations and their influence on curriculum and pedagogy. Attention is drawn to the significance of course content, practicum, critically reflective practice, and programme structures in relation to efforts to embed value orientations into teacher education programmes.

title: The kinetics of the dissociation of dihydroxyacetone dimer in aprotic media

authors: Owens, Adrian

subjects: Dihydroxyacetone

abstract: The dissociation of the dihydroxyacetone (DHA) dimer in mānuka honey has previously been proposed to be the rate determining step in the overall conversion of DHA to methylglyoxal, the agent reported to be responsible for the non-peroxide anti-bacterial activity displayed by mānuka honey.

The ¹H and ¹³C NMR spectra for the DHA dimer and the DHA monomer in DMSO-d6 were assigned using 1D and 2D NMR spectroscopy.

¹H and ¹³C NMR spectroscopy were utilised to investigate the kinetics of the dissociation of the DHA dimer in DMSO-d6, an anhydrous solvent chosen to mimic the dehydrating conditions present in the honey matrix.

Four series of kinetic experiments were conducted, one without catalysis, one with D₂O catalysis, one with CD₃COOD catalysis and one with CD₃COOD/CD₃COOD catalysis. Each of these experiments obtained the equilibrium constant, K and the rate constants k, k₁ and k₋₁ for the dissociation of the DHA dimer under different conditions that may be present in the honey matrix, with the exclusion of the CD₃COOD/CD₃COOD catalysed experiments which were conducted as part of the investigation to determine a proposed reaction mechanism.

Two reaction intermediates were observed in the CD₃COOD catalysed experiments, they were characterised and provided supporting evidence for a proposed acid-catalysed reaction mechanism for the DHA dimer dissociation. The absence of reaction intermediates in the D₂O catalysed experiments provided supporting evidence for a proposed base-catalysed reaction mechanism for the DHA dimer dissociation.

Reaction mechanisms for the DHA dimer dissociation in DMSO-d6 and mānuka honey were proposed based on the findings of previous studies and the findings associated with the kinetic experiments conducted in this study.

title: He Matapihi Mā Mua, Mō Muri: The Ethics, Processes, and Procedures Associated with the Digitization of Indigenous Knowledge—The Pei Jones Collection

authors: Whaanga, Hēmi

abstract: The digital era has transformed how people live their lives and interact with the world and knowledge systems around them. In Aotearoa/New Zealand a range of initiatives incorporating Indigenous knowledge have been implemented to collect, catalog, maintain, and organize digital objects. In this article, we report on the ethics, processes, and procedures associated with the digitization of the manuscripts, works, and collected taonga (treasures) of the late Dr. Pei Te Hurinui Jones—and describe how it was transformed into a digital library. It discusses the decision-making processes and the various roles and responsibilities of the researchers, family members, and institute in this process.
