title: Rangitoto volcano excursion, Auckland. Pre-conference field trip

authors: Lowe, David J.

abstract: Rangitoto is one of Auckland City’s more iconic landscape features. Guarding the entrance to the Waitemata Harbour, Rangitoto is a symmetrical, ~6-km wide, basaltic shield volcano that last erupted ~550 years ago shortly after the arrival and settlement of Polynesians in the Auckland region (c. 1280 AD). Rangitoto is by far the largest, and also the youngest, volcano in the Auckland Volcanic Field (AVF). The AVF is a monogenetic volcanic field consisting of approximately 53 individual eruptive centres, all of which are within the boundaries of the Auckland urban area. Recent research has revealed more about Rangitoto’s eruptive history, which may date back to c. 1500 years ago (Shane et al. 2013). Some of these findings have been noted below and will be discussed further while we ascend its summit and explore its various landscape and vegetational features.

title: Syntheses and ligand interconversions of copper(II) derivatives of the metalloligand [Pt₂(µ-S)₂(PPh₃)₄]

authors: Devoy, Sarah M.

abstract: The reactivity of the metalloligand [Pt₂(µ-S)₂(PPh₃)₄] towards a variety of copper(II)–ligand systems has been studied. Reaction of [Pt₂(µ-S)₂(PPh₃)₄] with copper(II) halide complexes [CuCl₂L](L = 2,2 -bipyridine and 1,10-phenanthroline) gave trinuclear dicationic products [Pt₂(µ-S)₂(PPh₃)₄CuL]²⁺, and the 8-hydroxyquinolinate (hq) complex [Cu(hq)₂] gave [Pt₂(µ-S)₂(PPh₃)₄Cu(hq)]⁺, isolated as their BPh₄⁻ or PF₆⁻ salts. Related cationic complexes with other ancillary amine ligands (1,2-diaminoethane, 1,2-diaminopropane, 1,2-diaminocyclohexane) were obtained by reactions of [Pt₂(µ-S)₂(PPh₃)₄] with CuCl2 and the amine. In contrast, reaction of [Pt₂(µ-S)₂(PPh₃)₄] with CuCl₂ and NH₃ in methanol gave the intensely blue methoxy-bridged dicopper complex [{Pt₂(µ-S)₂(PPh₃)₄Cu(OMe)}₂]²⁺, isolated as its hexafluorophosphate salt. Copper β-diketonate complexes reacted with [Pt₂(µ-S)₂(PPh₃)₄] giving [Pt₂(µ-S)₂(PPh₃)₄Cu(β-diketonate)]⁺PF₆⁻ complexes, with the CH₃COCHCOCH₃(acac) and CF₃COCHCO(2-thienyl)(tta) derivatives characterised by X-ray structure determinations. The local Cu(II) environment ranges from distorted square-planar to an intermediate form of square-planar and tetrahedral. The β-diketonate derivatives show varying stability towards methanolysis, giving [{Pt₂(µ-S)₂(PPh₃)₄Cu(OMe)}₂]²⁺.

title: Help or hindrance? New Zealand audience perspectives on subtitled media

authors: Kirk, Victoria

abstract: This research presents a picture of audiences’ patterns of engagement with internationally subtitled media in Hamilton, New Zealand. Utilising an audience reception framework to investigate audiences’ interactions with, and evaluations of subtitled media, this research unites the disciplines of Audio Visual Translation and Screen and Media Studies in a specific locale, with an emphasis on the reception of audio visual translated media. Findings in this research also provide a discussion of the wider contexts of audience reception in New Zealand, by investigating local subtitled media in relation to media accessibility processes found in the distinctive cultural landscape of New Zealand. Ultimately, this research finds the situation in New Zealand regarding audiences and the reception of both local English and Māori language media, as well as international subtitled media, exhibits complex polarisations in both the local translation industry production and audience attitudes towards bilingual media. In contrast to this, is the proliferation of international media with subtitles, which is appreciated by Hamilton residents since it provides diverse, accessible, and enjoyable content through a variety of media platforms.
