title: Measuring inter-indexer consistency using a thesaurus

authors: Medelyan, Olena

subjects: computer science

abstract: When professional indexers independently assign terms to a given document, the term sets generally differ between indexers. Studies of inter-indexer consistency measure the percentage of matching index terms, but none of them consider the semantic relationships that exist amongst these terms. We propose to represent multiple-indexers data in a vector space and use the cosine metric as a new consistency measure that can be extended by semantic relations between index terms. We believe that this new measure is more accurate and realistic than existing ones and therefore more suitable for evaluation of automatically extracted index terms.

title: Impacts of new technologies on household electricity demand: From an individual household, a community, and a national perspective

authors: Suppers, Joris

subjects: solar PV

abstract: In the last century, humans have invented and implemented numerous technological advancements, which have not only brought comfort and security to our lives, they have also opened up possibilities which were previously implausible e.g. long-distance transport and communication. The main energy sources to power these advancements have been fossil-fuels; mainly gas, coal and oil, causing side effects such as an increase in greenhouse gas emissions. The consequences of this increase are difficult to predict; however, it is likely to warm the earth, which could have severe outcomes e.g. a rise in sea levels. There has been a global movement to respond adequately to reduce human-produced greenhouse gas emissions. As part of this movement, the New Zealand government has proposed an energy strategy to reduce national greenhouse gas emissions, which includes decreasing the nation’s dependence on fossil fuels, and increasing renewable electricity generation to 90% by 2025. In New Zealand, the residential sector accounts for a large share of the national electricity demand, and vehicles driven in the country are predominantly fossil-fuelled. Therefore, the electrification of vehicles, and the inclusion of new technologies at a household level can have a significant impact on New Zealand achieving its energy strategy goals. The aim of this research, thus, is to provide a greater understanding of the impact electric vehicles, solar PV systems, and home energy storage systems within the household can have on electricity demand at a household, community, and national level. As part of this research: (1) a simulation tool, capable of calculating fine-grained (hourly) power output for solar panels at any location in New Zealand was created; (2) two small scale quantitative surveys were conducted to gather electricity usage data for New Zealand households; (3) a web interface allowing for a comparison of energy usage data from 32 different households was developed; (4) a modelling approach, capable of generating half hourly household electricity consumption data was constructed; and (5) a web-based tool, capable of simulating the impact of solar PV, an electric vehicle, and a home energy storage system, on electricity consumption was created.

title: A Mātauranga Māori Perspective of Literacy for Adult Learners

authors: Furness, Jane Amanda

abstract: Globally, literacy can be conceived of in different ways. Two perspectives that have influenced adult literacy policy internationally are the economic functionalist and the sociocultural. In Aotearoa New Zealand, Māori educators have repeatedly advanced a mātauranga Māori perspective of literacy. This perspective has parallels with the embodied, practice-based multiliteracies and sociomateriality of the sociocultural perspective but less so with the dominant functionalist perspective. To address how Māori views have been side-lined in adult literacy policy development, we seek to clarify this view and foreground Māori-led policy recommendations that date back to the creation of the New Zealand Adult Literacy Strategy in 2001. We also highlight the relevance of this perspective by sharing the success and effectiveness of Māori-led adult literacy programmes. In doing so, we demonstrate the need for a biliteracy approach to adult literacy policy to reflect our bicultural nation and ensure Māori aspirations for literacy are met.
