title: Platinum(II) complexes containing the 3,3-dimethylglutarimidate ligand

authors: Nair, Ashwin Gopalan

subjects: Crystal structure

abstract: Reaction of cis-[PtCl ₂(PPh ₃) ₂] with excess 3,3-dimethylglutarimide (dmgH) and sodium chloride in refluxing methanol gives the mono-imidate complex cis-[PtCl(dmg)(PPh ₃) ₂], which was structurally characterized. The plane of the imidate ligand is approximately perpendicular to the platinum coordination plane which, coupled with restricted rotation about the Pt-N bond, results in inequivalent methyl groups and CH2 protons of the dmg ligand in the room temperature ¹H NMR spectrum. These observations were corroborated by a theoretical study using density functional theory methods. The analogous bromide complex cis-[PtBr(dmg)(PPh ₃) ₂] can be prepared by replacing NaCl with NaBr in the reaction mixture.

title: Active Tephra in Kyushu 2010: International field conference

authors: Holt, Katherine A.

abstract: In May of 2010 the inter-congress meeting of the INQUA International Focus Group on Tephrochronology and Volcanism (INTAV) was held in Kirishima City, Japan. INTAV was formed in 2007 at the International Union for Quaternary Research (INQUA) congress held in Cairns. It replaced SCOTAV (Sub-commission on tephrochronology and volcanism), COT (Commission on tephrochronology), and earlier groups dating back to the 1960s. 
76 participants from 11 countries attended the INTAV-J meeting (Figure 1). The venue of the meeting was the Kokobu Civic Centre, which was very generously provided essentially free of charge by the Kirishima City authorities (in return for the delivery of two public lectures, one by David Lowe and the other by tephra/ volcano guru of Japan, Hiroshi Machida, on Sunday 9 May). Participants were treated to a personal welcome by the Mayor of Kirishima City, Shuji Maeda, followed by what appeared to be a very special (and delicious) banquet. However, this spread turned out to be standard lunch and dinner fare provided by the Civic Centre cafeteria and was enjoyed by participants on several occasions during the meeting. Mayor Maeda graciously invited the entire conference group to his personal residence for another spectacular banquet on Monday evening which included the use of dining ‘rooms’ in caves cut into the c. 30 cal. ka Ito ignimbrite. Traditional Kagoshima fare was put on, accompanied by the local alcohol ‘sho-chu’, which is made from fermented sweet potato and is not altogether unlike its Russian cousin vodka

title: Machine translation for te reo Māori

authors: Keegan, Te Taka Adrian Gregory

abstract: What is Machine Translation? Machine Translation (MT) is a process where computer software is used to translate texts from one natural (or spoken) language to another. Early research centred on two distinct approaches: Rules Based Machine Translation (RBMT) and Statistical Machine Translation (SMT). In simple terms RBMT makes use of large sets of linguistic rules that define languages whereas SMT uses statistical techniques to build language models from large language corpora. Increases in computing power and the amount of language corpora available has meant that SMT had become the preferred option with recent advances in neural networks also being applied to improve the accuracy of SMT. For commercial reasons, this is an area of research that has generated a lot of interest and funding support from some major international computer companies, including Google¹,Microsoft² and Facebook³.
Why is Machine Translation important for te reo Māori? A te reo Māori purist may argue that it is not important to focus activities on having a machine undertake translations for te reo Māori; if people want to understand te reo Māori then they should put in the effort to learn the language. This line of reasoning is difficult to argue with. But, from a Māori language activist perspective the value of MT is not so much in the translation of te reo Māori to (say) English, but rather the translation of English to te reo Māori. If this translation can be done efficiently, with low costs, it will assist in the proliferation of te reo Māori into new contexts, new environments and will assist its normalisation in New Zealand's society.
At this time, two of the major international companies, Google and Microsoft, have invested significantly in MT for te reo Māori. This paper summarises their endeavours and reports on the quality of translations they have been able to generate.
