title: Hyperspectral imaging and machine learning to identify epicuticular wax loss in Masena Blueberries for post-harvest freshness

authors: Pearse, Jonathan

abstract: Blueberries harvested using mechanical harvesting techniques, like over-the-row (OTR) harvesters, are not suitable for the fresh market due to high damage rates. Assisted harvesting (AH) techniques using hand-held shakers offer a new approach which shows promise in increasing harvesting rates without compromising fruit quality. Epicuticular wax is one of the fruit qualities needing to be preserved during harvesting. This paper investigates the effectiveness of hyperspectral imaging techniques and machine learning to construct a model to identify epicuticular wax rapidly and non-destructively. The best performing model produced was a linear SVM, and had an F1-score of 98.6%. Additionally, this model was used to show that blueberries harvested using hand-held shakers retain more epicuticular wax than traditional hand-harvesting (HH) techniques, a result that shows promise of potentially increased fruit quality using automated methods.

title: Construction and demolition Material Flow Analysis Data Base

authors: Nelson, Jacob Martin Bruton

abstract: The following document provides all of the data and estimates provided in the Material Flow Analysis Report. The focus of the report and database were to assess and estimate material flow at four key stages of construction and demolition in NZ. The data displayed in this database is focused on the material flow in residential construction and demolition.

title: An accountability model for Pakeha practitioners

authors: Huygens, Ingrid Louise Maria

subjects: Maori

abstract: This paper outlines a model of accountability for Pakeha practitioners developed over many years
as a practising community psychologist involved in research and development projects in Aotearoa
in the 1980s and 1990s, during an era of contract-funded health projects, and increasing
prominence of the Treaty of Waitangi2. The model could be termed 'transformative' in that it
reverses the usual flow of power by making the Pakeha practitioner accountable to relevant Maori
authority, and maximises the potential for new outcomes and new learning for all parties. A brief
case study is outlined where the model placed a local iwi governance structure and a national
psychiatric survivor organisation in positions of authority alongside the funder of a mental health
project. Helpful conditions, positive outcomes and barriers to transformative accountability
processes are briefly discussed.
