title: New MRI-safe Implant Electrode Design

authors: McCabe, Steven Owen

subjects: Science & Technology

abstract: Medical implants often prevent patients having Magnetic Resonance Imaging (MRI) scans because the leads behave as antennas with respect to the RF excitation and cause hazardous heating in neural tissue. This manuscript describes an approach that virtually eliminates the risk of RF heating by means of easily-incorporated, mutually-coupled filars. The resulting leads need be neither physically larger nor significantly more costly than existing designs. Combined with thin insulation and surface roughening techniques, this manuscript represents the first complete release of recently-patented technologies. Both simulations and measurements at 128MHz are presented to confirm performance in 3-Tesla MRI machines.

title: But the learning has already passed: Rethinking the role of time in e-mediated learning settings

authors: Khoo, Elaine G.L.

abstract: Time takes on a different character when online teachers take advantage of the possibilities for interactions occurring over different scales of time. Online teachers' pedagogical link-making becomes cumulative and progressive. This article reports on a qualitative case study of a fully online postgraduate course in Educational Research Methods within a New Zealand tertiary institution where the intention was to develop a learning communtity. The study was framed within a lecturer-researcher colllaborative approach to facilitate online lecturer devel;opment. Data collected from the online postings between lecturers and students, and among students and lecturer and student interviews, revealed how postings that point towards previous group ideas, current developing ideas and forward-focused ideas at pivotal points in the course supported student reflection, collaboration, and provided for socio-emotional support albeit in different ways and means. The authors argue that there is value in explicitly considering the mediating role of time when learning is understood as multidimensional and cumulative and provide implications for further research and practice.

title: He waipuna koropupū: Taranaki Māori wellbeing and suicide prevention

authors: Cameron, Ngaropi

abstract: The research project He Waipuna Koropupū aimed to explore and share a knowledge base that could inform practice in relation to Taranaki Māori suicide. The project was grounded upon the notion that through Taranaki knowledge and information we can make significant changes in our approach to life and to our whānau relationships. The project was primarily about whānau ora and the wellbeing of future generations; through the reclamation and sharing of Taranaki Māori knowledge that can support intergenerational change and transformation. Taranaki Māori whānau (extended family groupings), hapū (subtribal grouping) and iwi (tribal grouping) deserve access to Kaupapa Māori approaches in order to help reclaim and inform decision making processes.
