title: Preface: Enhancing tephrochronology and its application (INTREPID project): Hiroshi Machida commemorative volume

authors: Lowe, David J.

subjects: tephrochronology

abstract: Tephrochronology is the characterization and use of tephras – the explosively-erupted, unconsolidated, pyroclastic products of volcanic eruptions – or cryptotephras (glass-shard and/or crystal concentrations not visible as layers) as a unique stratigraphic linking, synchronizing, and dating tool. The word ‘tephra’ is derived directly from the Greek word tephra meaning ‘ashes’. Although the method is founded in stratigraphy, tephrochronology relies also on characterizing or ‘fingerprinting’ inherent tephra-derived components using laboratory-based analysis to complement field-based evidence. Such analysis includes the petrographic identification of mineral assemblages and the geochemical assay of glass shards, melt inclusions, or crystals (minerals including plagioclase, olivine, pyroxenes, amphiboles, biotite, or Fe–Ti oxides such as titanomagnetite) using the electron microprobe and other instruments including laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) ( [Lowe, 2011] and [1] ). These data are supported by the derivation of numerical ages on tephras/cryptotephras using a range of techniques including radiometric (e.g., radiocarbon, fission track, luminescence), incremental (e.g., layering in ice cores, varves, dendrochronology), age-equivalence (e.g., orbital tuning, magnetopolarity, palynostratigraphy), relative dating (e.g., obsidan hydration), and historical observation. Ages are also obtained using Bayesian-based flexible depositional modelling and wiggle matching (e.g., [Lowe et al., 2007] and Lowe et al., 2008 D.J. Lowe, P.A.R. Shane, B.V. Alloway and R.M. Newnham, Fingerprints and age models for widespread New Zealand tephra marker beds erupted since 30,000 years ago: a framework for NZ-INTIMATE.. Quaternary Science Reviews,  27  (2008), pp. 95–126. [Lowe et al., 2008] ).

title: An analysis of usage of a digital library

authors: Jones, Steve

subjects: computer science

abstract: As experimental digital library testbeds gain wider acceptance and develop significant user bases, it becomes important to investigate the ways in which users interact with the systems in practice. Transaction logs are one source of usage information, and the information on user behaviour can be culled from them both automatically (through calculation of summary statistics) and manually (by examining query strings for semantic clues on search motivations and searching strategy). We conduct a transaction log analysis on user activity in the Computer Science Technical Reports Collection of the New Zealand Digital Library, and report insights gained and identify resulting search interface design issues.

title: Whakaoranga taiao, whakaoranga tangata: The restorative, healing, and decolonising potential of environmental restoration

authors: Moore, Robert

abstract: This thesis explores the ways in which Māori who are involved in environmental restoration are able to use their experiences to reconnect with Te Ao Māori. Semi-structured interviews were conducted with three Māori who have been involved in environmental restoration in and around Kirikiriroa. These research participants were also able to speak to what they have observed in other restoration projects at their respective marae and comment broadly about this work as it is taking place across Aotearoa. It became clear through this research that the impacts of history and colonisation are still felt heavily by Māori in the environmental space today. For Māori involved in environmental restoration, this is a place where they are able to learn and share knowledge and reconnect with their Māoritanga. Environmental restoration can help restore wairua relationships with the whenua and strengthen Maori wellbeing through strengthening relationships with the whenua. Engaging in environmental restoration supports decolonisation as, for the aforementioned outcomes of doing so, being in these spaces supports the affirmation of an Indigenous identity.
