title: Synthesis and characterisation of [Pt₂(μ-S)(μ-I)(PPh₃)₄]⁺ – A cationic iodo analogue of the metalloligand [Pt₂(μ-S)₂(PPh₃)₄]

authors: Fong, S.W. Audi

subjects: platinum complexes

abstract: Reaction of [Pt₂(μ-S)₂(PPh₃)₄] with a number of transition metal–iodo complexes leads to the formation of the cationic iodo analogue [Pt₂(μ-S)(μ-I)(PPh₃)₄]⁺, identified using electrospray ionisation mass spectrometry (ESI MS). Synthetic routes to this complex were developed, using the reaction of [Pt₂(μ-S)₂(PPh₃)₄] with either [PtI₂(PPh₃)₂] or elemental iodine. The complex was characterised by NMR spectroscopy, ESI MS and an X-ray structure determination, which reveals the presence of a planar, disordered {Pt₂SI}⁺ core. Monitoring the iodine reaction by ESI MS allows the identification of various iodine species, including the short-lived intermediate [Pt₂(μ-S)₂(PPh₃)₄I]⁺, which allows a mechanism for the reaction to be proposed.

title: Power to the people: end-user building of digital library collections

authors: Witten, Ian H.

subjects: computer science

abstract: Naturally, digital library systems focus principally on the reader: th e consumer of the material that constitutes the library. In contrast, this paper describes an interface that makes it easy for people to build their own library collections. Collections may be built and served locally from the user's own web server, or (given appropriate permissions) remotely on a shared digital library host. End users can easily build new collections styled after existing ones from material on the Web or from their local files-or both, and collections can be updated and new ones brought on-line at any time. The interface, which is intended for non-professional end users, is modeled after widely used commercial software installation packages. Lest one quail at the prospect of end users building their own collections on a shared system, we also describe an interface for the administrative user who is responsible for maintaining a digital library installation.

title: From Darkness to dawn? A Forum for Kāpō Māori

authors: Te Momo, Ivan Prentus

subjects: Kāpō Māori

abstract: This thesis researches Kāpō Māori (Māori who are blind or sight impaired) and their pursuit of Te Reo Māori.  Te Reo Māori is a very significant cultural marker for Kāpō Māori to identify themselves as Māori.  Kāpō Māori face many challenges, challenges that are unknown to the mainstream.  The thesis surveys the fortunes of Te Reo Māori as it struggles to survive and find acceptance in Aotearoa/New Zealand, outlines attitudes towards disabled persons, who suffer discrimination and marginalisation, and summarises the story of the Blind in Aotearoa/New Zealand, especially through the history of The Royal New Zealand Foundation of the Blind, to provide context for the challenges faced by Kāpō Māori. For Kāpō Māori, discrimination and marginalisation is increased because all Māori suffer the disabilities that are a result of colonisation. The thesis sets out a methodology for field research, and draws from interviews with research participants to present the experiences of Kāpō Māori. This thesis provides an insight into the issues Kāpō Māori encounter when trying to engage Kāpō Māori , and draws those issues forward from darkness, where they are unknown, into the world of light by providing Kāpō Māori with a forum for discussion of these issues.
