title: Supercapacitor assisted LDO (SCALDO) techniquean extra low frequency design approach to high efficiency DC-DC converters and how it compares with the classical switched capacitor converters

authors: Kankanamge, Kosala

abstract: Supercapacitor assisted low dropout regulators (SCALDO) were proposed as an alternative design approach to DC-DC converters, where the supercapacitor circulation frequency (switching frequency) is in the order of few Hz to few 10s of Hz, with an output stage based on a low dropout regulator stage. For converters such as 12–5V, 5–3.3V and 5–1.5V, the technique provides efficiency improvement factors of 2, 1.33 and 3 respectively, in compared to linear converters with same input-output combinations. In a 5–1.5V SCALDO regulator, using thin profile supercapacitors in the range of fractional farads to few farads, this translates to an approximate end to end efficiency of near 90%. However, there were concerns that this patented technique is merely a variation of well-known switched capacitor (charge pump) converters. This paper is aimed at providing a broad overview of the capability of SCALDO technique with generalized theory, indicating its capabilities and limitations, and comparing the practical performance with a typical switched capacitor converter of similar current capability.

title: When Red Runs Blue: A collection of poetry taking back woman’s autonomy over our bodies

authors: Sadgrove, Amber

subjects: queer

abstract: Dear Vagina Owners/ Vagina admirers

Welcome to my body. When Red Runs Blue is a collection of poetry centred around menstruation, and exploring the complicated relationship between patriarchy and the female reproductive system. The reality of womanhood bleeds through these pages, in all frequencies, beautiful, violent, political. We are breeders but it is not safe to do so. Autonomous sexual desire is forbidden. This collection highlights the effects of silencing bleeders and the damaging consequences that have inevitably ensued. Come and explore this womb. My main three anchor points for these poems are menstruation, shame and sexual liberation for women.

My poetry touches on images of women’s menstrual bodies across history, showcasing how visceral mistreatment stretches from witch hunts and early insane asylums, to contemporary ways of looking at women as unstable and hysterical, so ingrained in our psyches as to become the norm. I also explore sapphic sexual relationships with and without the intrusion of the male gaze.

These are the voices of bleeders in both public and private spaces who have been shunned and put on the back burner simply because they have vaginas. My own determination to expose the rich, fleshly life of the body in vivid, defiant imagery  refuses to bow to patriarchal erasure and control. I want to give voice to the cycles, strains and stigmas that surround the womb, and celebrating the pleasures, powers and nourishment that still arise from its inner spaces.

title: Bilingual behaviour checklists: initiating a student, teacher and parent partnership in behaviour management.

authors: Glynn, Ted

subjects: bilingual education

abstract: Three bilingual (Maori and English) behavioural checklists formed part of a project designed to facilitate student, teacher and whanau collaboration in overcoming behavioural difficulties experienced by Maori students, (Hei Awhina Matua). The checklists assessed rankings by 163 students, 21 teachers and 96 whanau members of (1) contexts in which problem behaviours occur, (2) specific problem behaviours and (3) specific most valued behaviours. Data were gathered in three schools: a mainstream intermediate school with a Māori medium syndicate of three classes, a rural Kura Kaupapa Maori (Maori-controlled total immersion school) and a bilingual contributing primary school. While the three schools differed markedly in location, size, and in the proportion of Maori students enrolled, the rankings of settings and behaviours by students, teachers and whanau in each school were highly similar. The paper discusses how these data contributed to the design and development of the Hei Awhina Matua video and training manual, and provided a first step towards a collaborative student teacher and parent partnership in the management of student behaviour.
