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: Mass spectrometry-directed synthesis of  early–late  sulfide-bridged heterobimetallic complexes from the metalloligand [Pt₂(PPh₃)₄(μ-S)₂] and oxo compounds of vanadium(V), molybdenum(VI) and uranium(VI)

authors: Fong, S.W. Audi

subjects: chemistry

abstract: The metalloligand [Pt₂(PPh₃)₄(μ-S)₂] has been found to react with the transition metal oxo compounds, ammonium metavanadate, sodium molybdate, and the actinide complex uranyl nitrate to give sulfide-bridged heterobimetallic complexes [Pt₂(PPh₃)₄(μ₃-S)₂VO(OMe)₂]⁺, [Pt₂(PPh₃)₄(μ₃-S)₂MoO₂(OMe)]⁺, and [Pt₂(PPh₃)₄(μ₃-S)₂UO₂( ₂-NO₃)₂], respectively. Electrospray mass spectrometry (ESMS) was used to probe the reactivity of [Pt₂(PPh₃)₄(μ-S)₂] and thus identify likely targets for isolation and characterization. ESMS has also been used to investigate fragmentation pathways of the new species. No bimetallic species were detected with hydrated La(NO₃)₃or Th(NO₃)₄, or with the lanthanide shift reagent Eu(fod)₃ (fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate). X-Ray crystal structure determinations have been carried out on [Pt₂(PPh₃)₄(μ₃-S)₂VO(OMe)₂]⁺, 2, (as its hexafluorophosphate salt) and [Pt₂(PPh₃)₄(μ₃-S)₂UO₂( ₂-NO₃)₂], 4. The vanadium atom of 2 has a distorted square pyramidal geometry, while the uranium in 4 has the expected linear dioxo coordination geometry, with two bidentate nitrates and a bidentate {Pt₂S₂} moiety.

title: The sociocultural impact of tourism on the Te Arawa people of Rotorua, New Zealand

authors: Te Awekotuku, Ngahuia

subjects: Te Arawa

abstract: This is a study of how tourism in New Zealand has affected a major tribal community; their insights, reactions, and experiences. Covering five generations, it presents an oral account of the actively concerned social groups. Wherever possible, or necessary, this is reiterated and reinforced by the written record.

The work comprises two parts, the first which outlines the historic background according to available documentation, and the second which focusses on particular aspects of tribal culture and experience. Material for this section, otherwise unrecorded, came from the narrated stories, reminiscences, and often shrewd observations of the people themselves. It deals with residential community, song and dance, arts and crafts, and the role of women.

As an essentially ethnographic commentary, the study does not examine the economic features or effects of tourism, except where fiscal factors are pertinent to the understanding or continuity of the Te Arawa experience of the tourist world.
