title: Guest editorial Geography teaching, governance and professional development

authors: Chalmers, Lex

abstract: One of the things that have characterised the activity of secondary teaching in the last two decades has been the increasing impact of ‘governance’, where governance is taken to mean implementation and compliance with new curriculum and assessment frameworks, new teacher/school management and performance criteria andnewways of viewing educational practice. Governance issues affect teaching by consuming time that could more purposefully be directed to professional development, and this matter is the focus of this commentary.

title: Optimization of Sol–Gel-Formed ZnO:Al Processing Parameters by Observation of Dopant Ion Location Using Solid-State ²⁷Al NMR Spectrometry

authors: Kemmitt, Tim

subjects: chemistry

abstract: We report the discrimination of Al doping sites in sol–gel-formed ZnO powders by solid-state 27Al nuclear magnetic resonance (NMR) spectrometry. A degree of control of dopant placement is demonstrated by modifying sol precursors and processing parameters. ZnO powders containing 1–8 at. % aluminum ions were prepared from aqueous citrate-amino-alcohol-based gels calcined at 500 °C. The powders were characterized using ²⁷Al NMR spectrometry, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Solid-state ²⁷Al NMR spectrometry clearly distinguished between different Al environments and was effective in determining the relative amounts of incorporation of Al dopant ions into the Zn lattice sites in the zincite structure. This allowed a synthesis protocol to be developed to optimize the doping effectiveness. Relatively minor variations in processing conditions could influence the degree and mode of Al incorporation. Optimal conditions were found to include a 90 °C drying step, followed by placement in a preheated (500 °C) furnace for 1 h. An ethanolamine-containing precursor was shown to perform much better than precursors containing alternative amino alcohols.

title: Māori & Psychology Research Unit annual report 2010

authors: Rua, Mohi

subjects: Māori and Psychology Research Unit

abstract: Annual report of the Māori and Psychology Research Unit (MPRU) 2010. The unit was established in August of 1997. The unit is designed to provide a catalyst and support network for enhancing research concerning the psychological needs, aspirations, and priorities of Maori people. The MPRU is well situated to draw together skilled and experienced interdisciplinary research groups by networking and establishing working relationships with staff and students within the Faculty of Arts and Social Sciences, the University, and the wider community.
