title: Preparation and molecular structures of the decanuclear diynyl-ruthenium-silver and -copper complexes [M₆{μ₃-C CC C[Ru(dppe)Cp*]}₄(μ-dppm)₂](BF₄)₂ (M = Ag, Cu)

authors: Bruce, Michael I.

subjects: cluster

abstract: Reactions between [M2(dppm)2(NCMe)2]X2 [M = Ag, X = ClO₄; M = Cu, X = BF₄] and Ru(C CC CM)(dppe)Cp* [M = Ag, Cu; generated in situ from Ru(C CC CH)(dppe)Cp* and AgNO₃ or CuCl(PPh₃), respectively] afford the cationic mixed-metal cluster diynyl complexes [M₆{μ₃-C CC C[Ru(dppe)Cp*]}₄(μ-dppm)₂]X₂, of which the structures were determined by single-crystal XRD studies. Electrochemical studies indicate that there is no interaction between the ruthenium centres. Reactions between [M₂(μ-dppm)₂(NCMe)₂](BF₄)₂ and Ru(C CC CM′)(dppe)Cp* (M,M′ = Cu, Ag) afforded a mixture of Ag6−nCun clusters, as shown by ES-MS and crystallographic studies. Preliminary studies suggest that extensive disproportionation occurs in solution.

title: The art of mentoring: teaching that engages the soul.

authors: Gauthern, Dean

subjects: mentoring in education

abstract: This paper explores the important educational issue of the art of mentoring in education, particularly regarding teachers. Using a biographical example to illustrate, I focus upon nurturing and the soul, emotional and pedagogical qualities in mentoring, and draw attention to paradoxes and issues that make mentoring an endangered activity.

title: Invading the Waikato: A postcolonial re-view

authors: Dench, Simon

subjects: New Zealand

abstract: The article discusses images of the Waikato Region of New Zealand from the 1860s, examining them within the context of British colonization and invasion. It comments on photographs by surveyor Daniel Manders Beere and British Army Royal Artillery Regiment Assistant Surgeon William Temple. The author also comments on a map of New Zealand's North Island made by surveyor Charles Heaphy and a map of Newcastle, New Zealand, depicting its earlier names of Ngāruawāhia and Queenstown. Other topics include spatial history, postcolonialism, and the 1863 to 1864 British invasion of Waikato.
