title: Using augmented reality to enhance children’s books

authors: Vanderschantz, Nicholas

subjects: computer science

abstract: This paper reports a case study on using Augmented Reality in children's books in which we explored the use of various types of interactions at different levels. The paper describes the design process and the insights gained through investigations into the requirements for enhancing children’s books with Augmented Reality. Using evidence from the literature along with our own observations, an interaction design model and resulting interface design are developed to explore interactivity in printed books using Augmented Reality. We report on an expert walk-through and discuss possible improvements and implications from our case study.

title: Processibility of corn protein blends and resulting properties of the extrudates

authors: Rosentrater, Kurt A.

abstract: During the last decade, the global biofuels industry has experienced exponential growth. By-products such as high protein corn gluten meal (CGM) and high fibre distillers dried grains with solubles (DDGS) have grown in parallel. CGM has been shown to be suitable as a biopolymer; the high fibre content of DDGS reduces its effectiveness, although it is considerably cheaper. In this study, the processing behaviour of CGM and DDGS blends were evaluated and resulting extrudate properties were determined. Prior to processing, urea was used as a denaturant. DDGS:CGM ratios of 0, 33, 50, 66 and 100% were processed in a single screw extruder, which solely used dissipative heating, with a 2 mm circular die. Resulting screw speeds ranged from 216 to 228 rpm, and die exit temperatures ranged from 96 to 150oC. Blends containing DDGS were less uniformly consolidated and resulted in more dissipative heating. Blends showed multiple glass transitions, which is characteristic of mechanically compatible blends. Transmission electron microscopy revealed phase separation on a micro-scale, although distinct CGM or DDGS phases could not be identified. On a macro-scale, optical microscopy suggested that CGM-rich blends were better consolidated, supported by visual observations of a more continuous extrudate formed during extrusion. As with all biological materials, the extruded blends exhibited sorption behaviour over time, the magnitude of which varied according to blend ratio. EMC values ranged from approximately 0% to nearly 50%, depending upon the humidity level and blend ratio. Nonlinear regression was successfully used to model the effects of relative humidity and blend ratio on the equilibrium moisture contents, with a coefficient of determination of 99%. Future work should aim to also characterize the mechanical properties of these blends to assess their suitability as either bioplastic feedstock or pelletized livestock feed.

title: New Zealand English and Te Reo Māori: A critical perspective on the loanword narrative using data from translingual picturebooks

authors: Barbour, Julie Renee

subjects: language contact

abstract: Aims/Purpose: New Zealand English has been characterised by the use of vocabulary ‘borrowed’ from the Indigenous Māori language since early contact between English and Māori speakers. In this paper, we consider the relevance of the ‘loanword narrative’ to New Zealand English, examining data from translingual picturebooks published in Aotearoa New Zealand.
Design/Data: We built a small corpus of 10 translingual picturebooks spanning a 30-year period beginning in the early years of Māori language revitalisation.
Analysis: We applied techniques of language analysis from descriptive linguistics, including studies of loanwords.
Findings: We find some evidence of linguistic ‘borrowing’.
Originality: However, in texts created by Māori content creators, with Māori cultural themes, a language practice akin to pedagogical code-switching or pedagogical translanguaging is observed. Māori content creators alternate between languages, treating Māori lexemes as distinct from NZE, preserving Māori orthographic traditions, and providing translation, explanation, or contextual support of Māori lexemes for NZE reader comprehension. Our observations find parallels in translanguaging studies in bilingual early childhood settings, and they are supported by new psycholinguistic research that has identified the development of substantial body of linguistic knowledge about the Māori language by non-Māori speakers through societal exposure.
Significance: We argue that the prevailing loanword narrative does not account for Māori language usage in translingual picturebooks developed by Māori content creators. Rather, we find a clear pattern of differentiation between Māori and NZE.
