title: Damping properties and microstructure of magnetorheological composites based on iron sand and natural rubber

authors: Shuib, Raa Khimi

abstract: Material with high damping capability is desired from the viewpoint of vibration suppression in structures. Rubber is by far the most commonly used material for damping; here damping relies on the energy absorbed due to viscous flow that occurs during deformation in this viscoelastic materials. However, enhancement of damping through rubber modification or rubber selection to increase viscous flow, not surprisingly, generally results in a reduction in stiffness and strength [1]. More recently, a new class of damping materials, magnetorheological elastomers (MREs) have been developed such that inclusion of magnetic particles in rubber enables additional damping through magnetic particle interaction and interfacial friction. Furthermore, damping and stiffness can be varied by application of an applied magnetic field during fabrication or in service. MREs can be utilised for damping, either alone or within a composite structure such as those including steel plates.

title: Co-authoring new relationships at school through narrative mediation

authors: Williams, Michael

subjects: narrative

abstract: The practice of narrative mediation is illustrated through a case study for its applicability to the resolution of conflict in a high school. Two boys who had been fighting are brought together by a New Zealand high school counsellor to address their differences. Fighting is externalised and the boys are invited into a relationship story based on their own knowledge of ways to resist fighting. The mediation disrupts the conflict narrative and develops a counter-story of harmonious relationship. This article illustrates narrative mediation in action and provides a commentary to make it understandable and replicable for school counsellors. As a straightforward case study, the article does not make substantial claims for this practice but seeks to inspire further applications of narrative mediation by school counsellors.

title: Analysis of errors in the writing of first year university students of Māori

authors: Earnshaw, Lorene

subjects: Te reo Māori

abstract: This paper presents a survey of the range of grammatical and lexical errors made in written Māori by University students taking an introductory course in Māori language. We begin by introducing, and discussing the motivation for, an error classification system which accommodates different classes of error. We then provide an analysis of errors in three different types of student writing: homework assignments, impromptu tests and examination transcripts. We conclude with some remarks about the patterns of error which we found.
