title: 1080 and the fight to save New Zealand's wildlife

authors: Hansford, Dave

abstract: I grinned when I saw the title of the symposium was ‘Troublemakers’. I am here because I wrote ‘Protecting Paradise’ and in it I looked at the science around 1080. I explored some of the popular myths and fallacies around 1080, those intractable fallacies that do not go away. I was so intrigued that much to my editor’s concern I decided to find out why they are so intractable. Believe me that is a rabbit hole and I am going to take you as far down it as I can in 20 minutes.

title: Hydrogen bonding in crystalline alcohol solvates of the platinum(II) sulfido complex [Pt2( -S)2(PPh3)4]

authors: Henderson, William

subjects: Platinum complexes

abstract: Suspension of [Pt₂( -S)₂(PPh₃)₄] in lower alcohols results in recrystallisation, forming yellow to yellow-orange microcrystals of the solvates [Pt₂( -S)₂(PPh₃)₄]•nROH (R = Me, Et, nBu). The di-ethanol solvate was characterised by means of a single-crystal X-ray diffraction study and 1H NMR spectroscopy. The structure consists of an ethanol molecule hydrogen-bonded in an asymmetric bifurcated fashion to the {Pt₂S₂} group, with the second, disordered ethanol molecule involved in a cooperative hydrogen-bonding interaction with the oxygen of the first ethanol. Thermogravimetric analysis shows that the alcohol is relatively easily lost, regenerating orange, unsolvated [Pt₂( -S)₂(PPh₃)₄]. [Pt₂( -S)₂(PPh₃)₄] readily dissolves in hexafluoro-2-propanol, yielding yellow crystals of [Pt₂( -S)₂(PPh₃)₄]•6(CF₃)₂CHOH on evaporation. Characterisation by X-ray diffraction shows that the structure contains a [Pt₂ ( -S)₂(PPh₃)₄] hydrogen-bonded to a single(CF₃)₂CHOH molecule, with the additional (CF₃)₂CHOH molecules forming a discrete hydrogen-bonded pentameric cluster in the crystal.

title: Kōauau auē, e auau tō au e! The Kōauau in Te Ao Māori.

authors: Komene, Jo'el

subjects: Kōauau

abstract: In recent years there has been a revival of interest in traditional Māori musical instruments, including the kōauau. This thesis studies kōauau informed by a Māori framework, giving weight to traditional Māori knowledge and practices, emphasizing the spiritual dimensions of the instrument in its origins and its functions. The thesis defines the kōauau and how it is distinct from other taonga pūoro in its physical characteristics. It then presents the traditions associated with the kōauau which link its origins to the atua and their natural world, especially Raukatauri, together with other traditions from many rohe throughout Aotearoa.  The thesis describes the traditional tools and methods of construction, the role of atua in the construction process, materials used for kōauau, how they were embellished, and their use as adornments. The techniques for playing kōauau are analyzed, and there is a discussion of the occasions on which kōauau were played, and the purposes of performing on kōauau. The thesis also presents the texts of several traditional waiata kōauau. A number of traditional kōauau in storage at the Auckland Museum were able to be examined to confirm and extend documentary evidence about materials, construction methods, and embellishment. The discussion also comments on the quot;voicesquot; for those kōauau in the museum collection that could be sounded. The decline in kōauau performance during the twentieth century is outlined, and there is a summary of successful efforts in the later twentieth century to revive taonga pūoro, including kōauau. The thesis brings together in concise form much scattered information so that current and future performers with kōauau are able to give full consideration to its place in te ao Māori.
