title: Achieving sub-millimetre precision with a solid-state full-field heterodyning range imaging camera

authors: Dorrington, Adrian A.

subjects: range

abstract: We have developed a full-field solid-state range imaging system capable of capturing range and intensity data simultaneously for every pixel in a scene with sub-millimetre range precision. The system is based on indirect time-of-flight measurements by heterodyning intensity-modulated illumination with a gain modulation intensified digital video camera. Sub-millimetre precision to beyond 5 m and 2 mm precision out to 12 m has been achieved. In this paper, we describe the new sub-millimetre class range imaging system in detail, and review the important aspects that have been instrumental in achieving high precision ranging. We also present the results of performance characterization experiments and a method of resolving the range ambiguity problem associated with homodyne and heterodyne ranging systems.

title: Exploring leadership as a phenomenon in an educational leadership paper: An innovative pedagogical approach opens the unexpected

authors: Giles, David

subjects: Educational leadership

abstract: Neoliberal ideologies influence both the content and pedagogical approach of educational leadership programmes. This article proposes an alternate pedagogy, one which privileges the experiential nature of the leadership and challenges students to critique prevailing ideologies within education. The authors describe the reshaping of a compulsory, foundational academic paper within a Masters of educational leadership programme to focus on the phenomenon of leadership more explicitly. They illustrate the use of student stories and hermeneutic interpretation to deepen the appreciation of the contextual nature of educational leadership practice. The authors suggest that the influence of this pedagogical approach resides in the sincerity of the pedagogical comportment of the teaching faculty and the elusiveness of the taken-for-granted nature of leadership. They conclude that pedagogical processes that maintain a centrality of concern for the humanity of leadership experiences are a matter of urgency in our present educational context.

title: Kaitiakitanga o te Taiao - Reconciling Legislative Provisions and Outcomes for Māori

authors: Kennedy, Nathan Charles Karaua

subjects: Kaitiakitanga

abstract: The Resource Management Act (1991) (RMA) was heralded as internationally ground-breaking for its integrated approach, and for cementing 'sustainable management' as its overarching purpose. It was ground-breaking also for its recognition of First Nations’ rights and values. This includes directing decision-makers to recognise and provide for the relationship of Māori and their culture and traditions with their ancestral lands, waters and treasured resources, to have particular regard to Māori customary practices, and to take into account the principles of the Treaty of Waitangi. The RMA provides for councils to transfer or delegate functions and powers to Māori, and for joint management arrangements.
In 16 years as environment officer for my iwi, I witnessed the failure of the RMA to protect Māori values and interests. This experience prompted me to undertake research to thoroughly investigate outcomes of the operation of the RMA for Māori. Two questions framed my research; the first asking whether kaitiaki have been empowered by the Māori provisions in the RMA, and the second seeking to determine overall outcomes for Māori from the Act.
Assessing such outcomes required an understanding of Māori values and interests, evaluation of the law, of the statutory plans that govern council administration of the RMA, implementation of these by councils and the Crown, and their treatment by the courts. To answer the two questions I present in this thesis a geographically focused study of two take (causes or significant issues) at Whangamatā, the construction of a marina, and the removal of mangroves.
I compare Ngāti Whanaunga experiences with those of Māori nationally. By doing so I provide the evidence base for an 'overall broad judgement' (as the RMA requires) that despite apparent empowerment by the Act and its statutory plans, Māori have suffered widespread and significantly negative outcomes under the RMA. Rather than being empowered, Māori struggle to participate in planning processes, and see ancestral values and interests eroded by waves of resource consent processes, in which effects on Māori are little considered.
