title: The JStar language philosophy

authors: Utting, Mark

subjects: computer science

abstract: This paper introduces the JStar parallel programming language, which is a Java-based declarative language aimed at discouraging sequential programming, en-couraging massively parallel programming, and giving the compiler and runtime maximum freedom to try alternative parallelisation strategies. We describe the execution semantics and runtime support of the language, several optimisations and parallelism strategies, with some benchmark results.

title: Surge endurance capability testing of supercapacitor families

authors: Kularatna, Nihal

subjects: supercapacitors

abstract: Supercapacitors are usually low voltage, high capacity devices with milliohm order equivalent series resistances. They usually have time constants from fractional seconds to seconds. Due to these long time constants, compared to the time durations of power line transients in the range of few microseconds to several 100 microseconds, these devices may be able to withstand short duration surges with energy values specified in IEEE C62-41 series and IEC 61400-4-5 and similar standards. However there is little or no manufacturer data sheet information on these aspects. The paper provides the details of a test procedure to test the surge withstand capability of supercapacitors. In addition, essential details of a customized tester interface required for a lightning surge simulator and surge-endurance test results for three supercapacitor families are also presented.

title: Developing restorative practices in schools: Some reflections

authors: Drewery, Wendy

subjects: Counselling

abstract: The use of disciplinary practices derived from restorative justice have recently been gaining popularity and inciting keen interest in the education community. Practices that have so far been introduced have tended to centre on conferencing, although there is a broadening range of other practices in schools that are being brought under the heading “restorative”. This paper offers some reflections on these developments, building on the experiences of a team at the University of Waikato, which completed two projects on restorative conferencing in schools for the Ministry of Education under the rubric of the Suspension Reduction Initiative, and continues to develop understanding of the practices. The projects included developing and trialling processes for suspension hearings using restorative conferencing and principles from restorative justice. Objectives of both projects were related to the desire to reduce numbers of suspensions and exclusions, particularly of Māori children. We argue that the introduction of restorative practices invites schools into some tectonic shifts in thinking about offending behaviour, about community, and ultimately about the purposes of education.
