title: FreeForm: An informal environment for interface prototyping

authors: Plimmer, Beryl

subjects: computer science

abstract: Best practice in interface design suggests that hand-drawn sketches are preferable at the early stages of the design process. This paper describes the FreeForm software which supports informal sketched interface design by acting as a Visual Basic Add-In. The Software utilises a digital whiteboard and pen input to support sketching and “running” of an informal prototype.

title: Equilibrium and dynamic moisture adsorption behaviour of bloodmeal based bioplastic

authors: Lay, Mark C.

abstract: Bioplastics can be manufactured from protein or carbohydrate sources such as wheat gluten, corn, sun flower, keratin, casein, soy, gelatine and whey. A recently developed bioplastic is Novatein thermoplastic (NTP), which is produced from bloodmeal by adding water, urea, sodium sulphite, sodium dodecyl sulphate and tri-ethylene glycol (TEG), allowing it to be extruded and injection moulded. Bioplastics, compared to their petroleum counterparts, can readily adsorb or lose water, which then changes their physical properties such as tensile strength and glass transition temperature. NTP at different TEG and water contents was exposed to 20-85% relative humidity (RH) environments and change in mass recorded over 35 days to determine equilibrium and dynamic moisture adsorption behavior. Equilibrium behavior was modelled using modified Freundlich and Langmuir- Freundlich isotherms, and dynamic behavior modelled using Pilosof, Singh- ulshrestha, exponential, Langmuir-Freundlich and simple rate equations. Excellent fits were obtained for both isotherms and the last three rate equations gave best overall fits for dynamics. NTP adsorbed up to 28% by weight in water at 85% RH, reaching equilibrium within 20 days. Plastics with high TEG had a greater affinity for water but lower water adsorption rates, while dry plastic samples had a lower adsorption rate than wet samples. The two parameter Freundlich model and the exponential or simple rate model is recommended for modelling NTP equilibrium and dynamic water adsorption.

title: Māori Migration: The Social Consequences

authors: Nikora, Linda Waimarie

subjects: Maori

abstract: A team led by Bernard Guerin is looking at the family and community impacts from contemporary forms of migration in a 6-year project Strangers in Town: Enhancing Family and Community in a More Diverse New Zealand Society, funded by the Foundation for Research, Science and Technology. One large part of this research looks at Māori migration, headed by Linda Waimarie Nikora.
Since the research on the 'urban drift' of the 1950s and 1960s, little has been done to research the effects of Māori migration. Our aim is to draw together the researchers and research results and to conduct our own research to fill in the gaps. We also work with others on the 6-year project who are looking at the population statistics of Māori migration, especially Trans-Tasman migrations.
