title: Location-based vocabulary learning app

authors: Wu, Shaoqun

subjects: computer science

abstract: This paper presents a mobile app that generates vocabulary learning games based on the user’s geographical location—cinema, restaurant, museum, etc. The app sends the user a notification and offers three fun vocabulary games—Unscramble, Hangman and Matching—when the user enters the premises of the location of interest. This project used cinema halls as the primary location. The games are automatically generated from the movie words and phrases extracted from New York Times movie reviews. The user can either learn new words or review words learned previously. A preliminary study with seven language learners has shown learners’ positive attitude towards the underling principles of location-based vocabulary learning. It has also provided constructive feedback for the future development.

title: Coordination chemistry of the [Pt₂(μ-S)₂(PPh₃)₄] metalloligand with π-hydrocarbon derivatives of d⁶ ruthenium(II), osmium(II), rhodium(III) and iridium(III)

authors: Fong, S.W. Audi

subjects: mixed-metal complexes

abstract: The reactivity of [Pt₂(μ-S)₂(PPh₃)₄] towards [RuCl₂(η⁶-arene)]₂ (arene=C₆H₆, C₆Me₆, p-MeC₆H₄Pri=p-cymene), [OsCl₂(η⁶-p-cymene)]₂ and [MCl₂(η⁵-C₅Me₅)]₂ (M=Rh, Ir) have been probed using electrospray ionisation mass spectrometry. In all cases, dicationic products of the type [Pt₂(μ-S)₂(PPh₃)₄ML]²⁺ (L=π-hydrocarbon ligand) are observed, and a number of complexes have been prepared on the synthetic scale, isolated as their BPh₄− or PF₆− salts, and fully characterised. A single-crystal X-ray structure determination on the Ru p-cymene derivative confirms the presence of a pseudo-five-coordinate Ru centre. This resists addition of small donor ligands such as CO and pyridine. The reaction of [Pt₂(μ-S)₂(PPh₃)₄] with RuClCp(PPh₃)₂ (Cp=η⁵-C₅H₅) gives [Pt₂(μ-S)₂(PPh₃)₄RuCp]⁺. In addition, the reaction of [Pt₂(μ-S)₂(PPh₃)₄] with the related carbonyl complex [RuCl₂(CO)₃]₂, monitored by electrospray mass spectrometry, gives [Pt₂(μ-S)₂(PPh₃)₄Ru(CO)₃Cl]⁺.

title: He Whakaoranga Kia Puta Kia Ora (prepared for Health Research Council of New Zealand)

authors: Kilgour, Jonathan T.

abstract: This research project explored the relationship between cultural connectedness and wellbeing (as a social determinant of health). In particular, the research explored the diverse ways in which tribal members connected with and expressed their Waikatotanga.
