title: Chief’s Mana in action; a study investigating the team’s perspective.

authors: Howarth, Joelene

subjects: Sports psychology

abstract: Team culture, and its relevance to performance behaviour and attitudes, has recently gained increased focus in sport psychology research and practice (Schroeder, 2010; Cruickshank & Collins 2012; Morgan, Fletcher & Sarkar, 2014). Cruickshank and Collins (2012) state that“high performing cultures prevail when the shared perception and action of the elite team environment members; (a) supports sustained optimal performance; (b) persists across time in the face of variable results(i.e. wins, losses, ties); and most importantly, (c) leads to consistently high performance” (p.340). Spink et al. (2013) found preliminary evidence that a positive psychological climate, as defined by the significance and meaning of the work environment to the individual, is also linked to increased athlete effort. Various researchers suggests that it is a difficult task to change, cultivate and maintain a team culture, that is the social and psychological environment, which promotes best performance (Cruickshank & Collins 2012; Schroeder, 2010).

title: Reconnection with DNA: Policy and issues with direct-to-consumer DNA testing for indigenous Māori identity reclamation

authors: Turanga, Karen

abstract: The disconnection of tangata whenua (indigenous people born of the land) impacts all social determinants. A clear sense of identity and connection to the land and culture is an important solution to this problem. The purpose of this research is to share a personal and whānau (family group) story of using direct-to-consumer (DTC) autosomal DNA genetic testing (GT) to determine ancestry and show others a potential path forward to identity reclamation. To fulfil this purpose and explain the policy context, the research examines historical assimilation policies of closed cross-cultural adoption, and the possibilities DNA technology offers for whakapapa (genealogy, lineage descent, family history) reconnection. This includes addressing two key research questions: How does DTC-GT facilitate reconnection to Māori identity and whakapapa for cross-cultural adoptees? What are the short, medium and long-term risks and advantages of DTC autosomal DTC-GT testing for iwi Māori? A bricolage methodology frames this research and draws on kaupapa Māori (Māori approach, principles, and ideology), autoethnography, and interpretive phenomenology, which are used to analyse academic commentary and key policy decisions. An autoethnographic layered practice approach presents insights and key findings by combining personal narratives with various media types, academic research, policy documents and popular culture. The research highlights how the implicit processes of policy-led assimilation and colonisation still need to be challenged today. Existing literature has identified the importance of giving Māori pathways to reconnect with their identity. The personal story shared explains how DNA technology offers a way to do that, but the research completed for this thesis demonstrates this approach has serious risks and limitations that require consideration before utilising this technology.

title: Multiple return separation for a full-field ranger via continuous waveform modelling

authors: Godbaz, John Peter

subjects: lidar

abstract: We present two novel Poisson noise Maximum Likelihood based methods for identifying the individual returns within mixed pixels for Amplitude Modulated Continuous Wave rangers. These methods use the convolutional relationship between signal returns and the recorded data to determine the number, range and intensity of returns within a pixel. One method relies on a continuous piecewise truncated-triangle model for the beat waveform and the other on linear interpolation between translated versions of a sampled waveform. In the single return case both methods provide an improvement in ranging precision over standard Fourier transform based methods and a decrease in overall error in almost every case. We find that it is possible to discriminate between two light sources within a pixel, but local minima and scattered light have a significant impact on ranging precision. Discrimination of two returns requires the ability to take samples at less than 90 phase shifts.
