title: Collaborative relationships in practice: Possibilities and challenges

authors: Mitchell, Linda

subjects: education

abstract: The following three papers examine what collaboration is happening in New Zealand’s early childhood education services currently, and provide exemplars of collaboration in three key areas: with parents and whänau; with Mäori, iwi and marae; and with local Pacific and other ethnic communities. We emphasise some differences in needs and priorities for different service types, and challenges for each. Finally, we discuss the extent to which government and umbrella group systems and policies support early childhood education services to create collaborative relationships. These papers draw from the findings of four recent research projects: An Evaluation of the Initial Uses and Impact of Equity Funding; Quality in Parent/Whänau-led Services; phase 1 of a Locality-based Evaluation of Pathways to the Future – Ngä Huarahi Arataki; and NZCER’s national survey of early childhood education services carried out in late 2003 and early 2004.

title: Geothermal energy, decarbonisation and the just transition: developments in governance and regulation

authors: Parson, Phoebe

abstract: This review article pursues this special issue’s theme of renewable energy and just transition into the field of geothermal energy, an energy source which has a special role in Aotearoa New Zealand, and which raises clear questions of justice in the energy transition. It evaluates the track record, and examines the legal, regulatory and institutional challenges and opportunities for a just transition for geothermal in New Zealand. It particularly considers the role of Māori, and the challenges presented by emerging technological change. It considers the problems of renewability and sustainability that are special to geothermal resources. It evaluates the just transition issues that have particularly affected Māori landowners and holders of mana whenua. It finds that what constitutes a just transition must be seen against a longer historical time frame than many observers might assume. It shows that the distinctive regulatory framework for geothermal has been considerably affected by addressing these problems but may need to adapt further in the future. It considers the technical features that have shaped geothermal regulation and are likely to shape it in the future as new technological options emerge.

title: An investigation of the stability of yacon storage roots under commercial conditions and the feasibility of preparing blackcurrant-yacon juice mixtures for the retail market

authors: Revell, Maria Teresa

subjects: yacon

abstract: The stability of fructooligosaccharides (FOS) was investigated in yacon (Smallanthus sonchifolius Poepp. & Endl., Asteraceae) storage roots and blackcurrant-yacon juice mixtures. The roots and syrup are from yacon plants grown for NZ Biotechnologies, the only company in New Zealand licensed to grow yacon commercially for export.
The hydrolysis of FOS in storage roots packaged in a semi-permable polymer was significantly reduced compared to unpackaged roots from the same plant, stored in the same conditions (5 °C for up to 72 days). The effectiveness of the packaging was dependent upon a complete seal around the root, indicating the need for selection of relatively straight and smooth roots for successful packaging.
Blackcurrant-yacon juice mixtures offer the prebiotic effect of FOS combined with the antioxidant activity of blackcurrant juice. This study was designed to assess the effect of pasteurisation conditions on carbohydrate and polyphenol concentrations and antioxidant activity. The reduction in active ingredients per mL can then be compensated for by the initial formulation before pasteurisation.
The rates of hydrolysis and release of FOS, 1-kestose, sucrose, D-glucose and D-fructose were calculated and agreed with previous studies with the exception of 1-kestose. The initial concentrations of polyphenols (330.67-524.4 gallic acid equivalent mg L⁻¹) and anthocyanins (1013.11-1362.25 cyanidin-3-glucoside equivalent mg L⁻¹) were also similar to other studies. The concentration of both polyphenols and anthocyanins decreased with heating time, but this difference was statistically significant at a 99.95 % confidence level only for anthocyanins.
 The decrease of anthocyanin concentration with time in blackcurrant-yacon juice without pH stabilisation was correlated with the rate of FOS hydrolysis. This indicates that the presence of FOS stabilizes the anthocyanins possibly by formation of a complex or compound. This is supported by evidence from elsewhere that dietary fibre-type molecules can transport antioxidants to the large bowel, with associated health effects.
