title: The role of smart community microgrids in Aotearoa’s energy future

authors: Apperley, Mark

subjects: Renewable energy

abstract: There is a pressing need to expand electricity production in Aotearoa New Zealand to meet sustainability goals and lower energy costs. This new generation needs to be based on renewable sources, chiefly wind and solar, for both sustainability and economic reasons. While there remains a role for the legacy grid, microgrids provide a means of co-locating generation with load, minimising transmission line investment and energy losses. This paper explores the advantages of smart community microgrids in this context, but also examines the challenges in terms of the existing legacy grid approach. Three case studies are given as examples, covering an isolated community with no grid connection, a more conventional residential community of 30 households, and a community with local commercial/industrial loads in addition to housing. These case studies show the benefits in terms of local consumption of locally generated electricity coupled with sharing or local trading within the community. Microgrids can support New Zealand’s transition to a more electrified, equitable, economical and low-emissions energy system, but their development does require not just exploitation of new technologies, but also adjustment to the legacy grid model and a fresh approach to electricity infrastructure planning and management.

title: A survey of Vietnamese EAP teacher’s beliefs about grammar teaching

authors: Van Canh, Le

subjects: grammar

abstract: Although it is now generally agreed that grammar should be an integral element of second language programmes, there is still a diversity of opinions about how it should be taught. In this paper, attention is first drawn to relevant issues raised in reviews of the teaching of grammar derived from SLA research and teacher cognition. This paper then reports a survey of Vietnamese teachers‟ attitudes towards grammar and grammar teaching in their own particular teaching contexts. It uses a questionnaire adapted from that used by in a 2002 survey of teachers of English for Academic Purposes (EAP) in British universities and in a 2008 parallel survey of EAP teachers in New Zealand. The findings of the present study indicate that, like the teachers reported in the 2002 and 2008 studies, EAP teachers in Vietnam appreciate the centrality of grammar in their language teaching and have a critical awareness of many of the problems and issues involved. The findings suggest that the teachers favour a discourse, rather than a decontextualised approach to the presentation of grammar and there is an emphasis on systematic practice of grammatical forms and the correction of grammatical errors.

title: An investigation by LA-ICP-MS of possum tooth enamel as a model for identifying childhood geographical locations of historical and archaeological human from New Zealand

authors: Cameron, Kristie Elizabeth

subjects: LA -IC P-MS

abstract: LA -IC P-MS (laser ablation-inductively coupled plasma-mass spectrometry) has been used to analyse enamel from the teeth of brushtail possum (Trichosurus vulpecula) in order to model a method for identifying the childhood geographical origin of human remains within New Zealand. The model application of the method is promising for establishing locations of historical and archaeological human remains, including preserved heads, upoko tuhi.
