title: A dynamic and flexible representation of social relationships in CSCW

authors: Jones, Steve

subjects: computer science

abstract: CSCW system designers lack effective support in addressing the social issues and interpersonal relationships which are linked with the use of CSCW systems. We present a formal description of trust to support CSCW system designers in considering the social aspects of group work, embedding those considerations in systems and analysing computer supported group processes. 
We argue that trust is a critical aspect in group work, and describe what we consider to be the building blocks of trust. We then present a formal notation for the building blocks, their use in reasoning about social interactions and how they are amended over time. We then consider how the formalism may be used in practice, and present some insights from initial analysis of the behaviour of the formalism. This is followed by a description of possible amendments and extensions to the formalism. We conclude that it is possible to formalise a notion of trust and to model the formalisation by a computational mechanism.

title: Production of soya milk containing low flatulence-causing oligosaccharides in a packed bed reactor using immobilised α-galactosidase

authors: Rajan, Anila

subjects: flatulence

abstract: Peanut α-galactosidase was immobilised in calcium alginate beads and used to hydrolyse the flatulence-causing oligosaccharides, raffinose and stachyose, in soya milk in batch and in packed bed reactor with recycle. The immobilised enzyme exhibited a slightly lower activity than the free enzyme. The activity yield of immobilised  -galactosidase was 75.1% and the immobilisation yield was 82.6%. Batch hydrolysis using immobilised enzyme at 55 °C resulted in 96% reduction in the oligosaccharides after 12 h. For the continuous process, a packed bed reactor with recycle was used. More than 98% of the oligosaccharides were hydrolysed after 6 h of reaction at 55 °C. The immobilised enzyme also proved to be stable up to three repeated hydrolysis reactions.

title: Restorying the individual: The cultural dimension of special education in three Te Arawa sites

authors: Macfarlane, Angus H

subjects: Māori special education

abstract: On the basis of observation of three Te Arawa educational sites, it is argued here that a central characteristic of successful programmes that attend to Māori students with special needs is cultural-centredness. Significant aspects of that culture-centredness are outlined here, aspects that, it is argued, are fundamental to the process of restorying that is, it is argued, critical to the success of many Māori students, particularly those with special needs.
