title: Supercapacitor-assisted LED (SCALED) technique for renewable energy systems: a very low frequency design approach with short-term DC-UPS capability eliminating battery banks

authors: Jayananda, Dilini

subjects: Science & Technology

abstract: The fluctuating nature of solar energy necessitates suitable energy storage systems. Compared to typical battery banks, supercapacitors offer longer cycle life eliminating the need to replace them regularly. However, compared to a typical maximum power point tracking controller, where the battery bank and resistive load fed by a switch-mode DC–DC converter allows impedance matching for maximum power transfer, a supercapacitor bank's significantly large capacitive load does not permit the typical impedance matching for maximum power transfer. This study compares the theoretical difference between battery versus supercapacitor energy storage, and highlights of the supercapacitor-assisted LED converter technique in achieving high-efficiency renewable energy-based DC-microgrid systems.

title: The ‘problem’ of Asian women’s sexuality: public discourses in Aotearoa/New Zealand

authors: Simon-Kumar, Rachel

subjects: Asian

abstract: Public health research in New Zealand views Asian health - particularly, Asian women's sexual health issues - as a priority problem. In recent years, high rates of abortion and the growing incidence of unsafe sex among younger age Asian migrants have been publicised as a health concern. Public health research implicates migrant experiences and cultural factors as responsible for these trends. Loneliness and isolation among international students, inability to communicate effectively in English and lack of knowledge of available services are highlighted as reasons for the growing sexual ill-health in the Asian population in New Zealand. Extending from these, public health measures aim at improving culture-sensitive services, including targeted education. The present paper offers a critical commentary on these accepted public health perceptions that inform policy in New Zealand. It takes a Third World feminist approach to critique dominant public health discourses on Asian women's sexuality and questions the construction of knowledges about what are 'normal' and 'pathological' sexual practices. The paper revisits the data used to describe the 'problem' of Asian sexuality and argues that in order to understand sexual practices, it is important to query the cultural lenses that are used to describe and define them.

title: Māori and Pacific language data in linguistics classes

authors: Barbour, Julie Renee

abstract: Māori and Pacific language data rarely appears in introductory linguistic text books. In a discipline with a dearth of Māori and Pacific scholars, there is an opportunity to reflect on our teaching materials and consider ways in which we can make our classes more inclusive spaces. In this presentation, we share some of the materials and associated activities that we incorporate into undergraduate linguistics classes, in an effort to make our disciplinary content more attractive to students who join our classes with a variety of heritage languages.
