title: Rubidium-templated bowl-shaped isopolyoxoantimonates [RbH₁₁˗ₓ(RSb)₁₄O₃₄]ₓ˗ derived from arylstibonic acids

authors: Nicholson, Brian K.

subjects: Polyoxometalates

abstract: Arylstibonic acids, RSbO₃H₂ (R = p-MeC₆H₄- or p-ClC₆H₄-) when neutralised in the presence of Rb⁺ give isopolyoxometalates derived from [RbH₁₁(RSb) ₁₄O₃₄]. The X-ray crystal structures of four examples were determined and all gave the same basic framework with a bowl-shaped Sb14 polyhedron cradling the Rb⁺ in an 11-coordinate embrace. All were further linked into chains in the lattice by an intermolecular interaction involving a second Rb⁺, coordinated to three O atoms of one polyoxometalate and to an aryl group of an adjacent unit via an η⁶ interaction. One example has the same basic structure but with one framework O atom replaced by a Br.

authors: Lowe, David J.

abstract: Michael Selby died in Auckland on 21 January 2018 aged 82. In his professional career as an Earth scientist at the University of Waikato for nearly 40 years, Michael began as a junior lecturer and ended as deputy vice chancellor (Fig.1). He played a pivotal role in helping to establish the Department of Earth Sciences, and its unique, integrative multi-disciplinary approach, at the University of Waikato from 1970.

title: Tikanga Tainui: Tikanga whare wānanga

authors: Roa, Tom

subjects: Tikanga Māori

abstract: This paper is a preliminary report on an ongoing research project begun in 1999. The project involves consultation with Waikato-Tainui, the tāngata whenua of the Waikato region, about the construction of guidelines for University of Waikato staff (both Māori and non-Māori) who are involved in gatherings that call for adherence to Tainui protocols. Here, the emphasis is on guidelines for the conduct of pōwhiri (formal welcomes) on the University Marae.
