title: The Library Consortium of New Zealand's Shared IRR Infrastructure

authors: Brown, Allison

subjects: institutional repositories

abstract: The Library Consortium of New Zealand has run an Institutional Research Repository Project for three universities and one institute of technology in New Zealand since 2006. After a brief introduction to the context in which the project operates, this document describes the Institutional Research Repositories that are part of this project and their shared infrastructure. Particular emphasis is placed on advantages and challenges created by the shared infrastructure.

title: Energy-Efficient SMPS-Based Pulse Generator for Neurostimulators

authors: Seshadri, Sinduja

subjects: pulse generator

abstract: There is a need in the neuromodulation industry for a very energy-efficient pulse generator. Little data is observed in literature to develop a power efficient pulse generator that can deliver the required stimulus. A typical stimulator has a boost stage, a low-dropout (LDO) stage and an analog circuit that delivers the stimulus in the form of a pulse to the patient. Such a system is found to be ∼ 40% efficient. There are two new methods that can improve this efficiency rating significantly. (1) A mod- ification to existing pulse generator by adding microprocessors to control the output voltages of boost and LDO in the circuit, as proposed by the manufacturer; (2) a Single-Ended Primary Inductance Converter (SEPIC) based design proposed by the authors, with the input connected to a battery and the output to electrodes. Comparing with existing design, the modification offered a consistent 75% efficiency for output voltages from 3.9V to 6.6V. SEPIC had an efficiency rating of 80% to 86% across the same voltage range.

title: Re-designing the national imaginary: The development of Matariki as a contemporary festival

authors: Hardy, Ann

subjects: Aotearoa/New Zealand

abstract: This article considers the factors shaping the contemporary redevelopment in Aotearoa/ New Zealand of the indigenous commemoration of the rising of the constellation Matariki as a marker of seasonal change.  Through interviews with producers of media materials celebrating Matariki, it examines the ideological, cultural, and economic factors determining the encoding of the materials, investigating in particular the ways in which Matariki can resource a marketplace for spiritual commodities.
