title: Connecting, synchronising, and dating with tephras: principles and applications of tephrochronology in Quaternary research

authors: Lowe, David J.

abstract: Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects or correlates deposits from one place to another. Secondly, it relies on characterising and hence identifying or ‘fingerprinting’ tephra layers using either physical properties evident in the field or those obtained from laboratory analysis, including mineralogical examination by optical microscopy or geochemical analysis of glass shards or crystals (e.g., Fe-Ti oxides, ferromagnesian minerals) using the electron microprobe and other tools. Thirdly, the method is enhanced when a numerical age is obtained for a tephra layer by (1) radiometric methods such as radiocarbon, fission-track, U-series, (U-Th)/He, or Ar/Ar dating, (2) incremental dating methods including dendrochronology or varved sediments or layering in ice cores, or (3) age-equivalent methods such as palaeomagnetism or correlation with marine oxygen isotope stages or palynostratigraphy. Once known, that age can be transferred from one site to the next using stratigraphic methods and by matching compositional characteristics, i.e., comparing ‘fingerprints’ from each layer. Used this way, tephrochronology is an age-equivalent dating method.

title: Using digital storytelling as a methodology for the introduction of socially responsible graphic design in a University Bachelor of Computer Graphic Design Programme

authors: Vanderschantz, Nicholas

subjects: computer science

abstract: This paper case studies the pedagogical methodology for a digital storytelling project involving final semester Bachelor of Computer Graphic Design students and students from a community based charitable arts trust. A young artist is paired with a senior tertiary graphic design student to create digital narratives that attempt to remain within the spirit of the original goals of the Digital Storytelling Movement. The project aims to introduce socially responsible graphic design to tertiary computer graphic design students and foundation arts students. Discussion of the learning outcomes of this project, including analysis of the results of the personal breakthroughs made by students as seen in their written accounts in project completion surveys are detailed.

title: A step into the light: developing a culturally appropriate research prcoess to study Maori Rangatahi perspectives of leisure in one setting.

authors: Harvey, Geraldine

subjects: research -- methodology

abstract: There is little knowledge of Maori peoples' leisure understandings, experiences and participation. This article reports on the development of a culturally appropriate research process that investigated the leisure participation, perspectives, and experiences of five Rotorua Maori Rangatahi in one research setting'. Within this exploration there is a focus on the need to conduct leisure research with Maori people in culturally appropriate ways. This research approach incorporates focus group methodology within a Kaupapa Maori research framework which addresses issues of research for Maori. The research process revealed that focus group methodology can be adapted into a Kaupapa Maori research framework and that this research approach could be an important tool when conducting research with Maori Rangatahi, including in educational contexts.
