Investigating educative mentoring for provisionally certificated teachers in the New Zealand primary school
Authors:   , Stannard Diane 
Published: November 2021

<p>The Guidelines for Induction and Mentoring and Mentor Teachers were published in 2011 by the New Zealand Teachers Council. The Guidelines signalled a shift from what had been an induction programme based on advice and guidance to one that involved educative mentoring. These guidelines were developed to support the provision of nationally consistent, high quality, and comprehensive support for provisionally certificated teachers (PCTs). This qualitative investigation used an interpretative case study approach to describe what educative mentoring looked like in three New Zealand primary schools. Data were gathered using an online survey, interviews, recorded meeting and analysis of documents. The findings were that mentors and provisionally registered teachers had differing levels of understanding of educative mentoring. While mentors espoused using educative mentoring components (Education Council of Aotearoa New Zealand, 2015a, pp. 25-26) this did not appear to be happening in practice. This suggests the need for mentor training if educative mentoring is to become embedded. Mentors need training to understand what educative mentoring really means. In particular the elements of deconstruction (describing, analysing, and discussing evidence) and co-construction (setting new personal goals) were missing to some degree in each relationship investigated. The process of induction and mentoring is to develop practice and ultimately for the provisionally registered teacher to attain the Practising Teacher Criteria. However this study revealed that the developmental process of practice appears to be more focused on meeting the Practising Teacher Criteria than developing understanding through the setting of personal goals.</p>
Factors Influencing Consumer Trust in Mobile Payments in the United Arab Emirates
Authors:   , Shuhaiber Ahmed 
Published: November 2021

<p>While mobile payments have been adopted by a huge number of businesses, the body of knowledge regarding user trust in mobile payments shows that trust is a major issue in its adoption and development. The purpose of this study was to better understand the factors that influence consumer trust in mobile payments in one significant country in this region; The United Arab Emirates (UAE) as the research region. The UAE is one of the leading economies in the Middle East Arab region, and mobile technology is well advanced and widely utilised. An analysis of relevant literature provided the basis for the development of a conceptual model. The model, classified into five logical groups (consumer characteristics, environmental influences, provider characteristics, perceived risks and mobile-device characteristics), was further explored, validated, extended and tested through a mixed-method methodology, combining both qualitative (phase one) and quantitative (phase two) approaches, with semi-structured interviewing in exploratory focus groups and an online survey being used respectively. The findings of the qualitative phase were used to clarify the appropriateness of the preliminary Consumer Trust in Mobile Payments (CTMP) model, which was accordingly revised and extended. The second phase (the quantitative approach) was based on a survey of 340 respondents in the UAE. The collected data were analysed by using Structural Equation Modelling with the Partial Least Squares (PLS-SEM) approach. Many of the factors in the qualitative CTMP model were successfully validated and statistically significant. The resulting, quantitatively weighted CTMP model shows that users‟ awareness and provider‟s trustworthiness are the most positive influential factor, followed by perceive security levels and device-design suitability. Customers‟ uncertainty avoidance, on the other hand, is the most negatively influential factor on trust, followed by perceived privacy risks associated with m-payments. The model contributes towards better acceptance and usage of mobile payments. The findings also provide a number of theoretical implications for academic research and useful information for practitioners.</p>
The molecular forms of BMP15 in a range of mammalian species
Authors:   , Swinerd Gene 
Published: November 2021

<p>BMP15 is an oocyte-secreted growth factor that is critical for ovarian follicular development and fertility in mammals. To improve our understanding of the species-specific effects of BMP15 on fertility, the aim of this study was to elucidate the molecular forms of BMP15 in mammals with high (rat and pigs) and low (sheep and deer) litter sizes. Western blotting experiments were undertaken using a monoclonal antibody directed against a semi-conserved area on the mature region of E.coli-expressed ovine BMP15. Within the oocyte lysate of all species tested, the predominant form was promature BMP15, although mature BMP15 was also present. Within oocyte-conditioned media of sheep, pigs and deer, the promature:mature BMP15 ratio dropped significantly from what was seen inside the oocyte, with promature BMP15 only slightly predominant in deer, and relatively equal amounts of each protein were present in pigs and sheep. No BMP15 was detected in the oocyte-conditioned media of rats. Cross-linking studies did not provide any evidence of BMP15/BMP15 homodimers or BMP15/GDF9 heterodimers in any species tested. Intra-oocyte levels of both promature and mature BMP15, from highest to lowest, were detected in deer, followed by sheep and pigs (similar), and then rats (significantly lower). In the oocyte-conditioned media, with the exception of the rat where BMP15 was absent, there was a similar pattern of promature BMP15 levels observed between species, whereas mature BMP15 levels showed no inter-species variation. In summary, the molecular forms and relative amounts of BMP15 protein differ across species. Generally, high BMP15 levels were associated with low litter size; however the pig is an exception. Furthermore, the molecular forms observed in this study differed from those reported in studies using recombinant BMP15 suggesting that recombinantly-expressed protein may not provide a fair representation of native BMP15.</p>
Seismic investigations of the lithosphere in an amagmatic back-arc region: North Island, New Zealand
Authors:   , Dimech Jesse-Lee 
Published: November 2021

<p>New seismic constraints on crustal and upper mantle structures, kinematics, and lithospheric rheology are reported from an amagmatic back-arc region: the southwest North Island of New Zealand. Robust earthquake locations reveal a hypocentre 'downwarp' beneath the east-west trending Taranaki–Ruapehu Line. These earthquakes occur in the uppermost mantle, at depths of 30–50 km, and are distinct from shallower 8–25 km-deep earthquakes near Mt. Ruapehu in terms of focal mechanisms and principal stress directions. A receiver function CCP stack shows that the mantle earthquakes occur beneath a large change in crustal thickness, where the Moho 'steps' from 28 to 35 km-deep and the steepest part of that step has a 20–50° dip. The mantle earthquakes are dominated by strike-slip fault movement and have a maximum compressive stress direction of NE–SW. The existence of mantle earthquakes beneath a steeply-dipping Moho step implies some sort of dynamic modication is occurring in the mantle lithosphere. One possibility to explain these features is the convective removal of the mantle lithosphere due to a Rayleigh–Taylor-type instability. South of the Taranaki–Ruapehu Line, the Moho conversion weakens on both the receiver function CCP stack, and marine seismic reflection data under most of the Wanganui Basin (SAHKE02 and GD100 seismic lines). However, localised bright reflections at Moho depths can be seen in both near-vertical and wide-angle seismic data. Attribute analysis of near-vertical seismic reflections suggests that the rocks beneath the reflectivity are strongly-attenuating (Q ~20) with a negative velocity contrast relative to the lower crust. These observations are interpreted to be related to the presence of serpentinite (antigorite) and/or high pore fluid pressures in the mantle wedge. The links between hydration of amagmatic back-arcs, serpentinisation and/or high pore fluid pressures, rock viscosity, and mantle instabilities are documented here for the southwest North Island of New Zealand. These associations may be applicable to other amagmatic back-arcs around the world.</p>
REDD+ Governmentality: Governing Forest, Land, and Forest Peoples in Indonesia
Authors:   , Astuti Rini Yuni 
Published: November 2021

<p>Aimed at lowering forest carbon emissions through financing improved forest governance and socially inclusive land and natural resources use, the REDD+ (Reducing Emissions from Deforestation and Forest Degradation Plus) program is attracting widespread interest and investment in Indonesia. REDD+ introduces new governmental rationalities, in which forest carbon is used as a standard to measure a country’s performance in keeping its tropical forests intact and defines the financial rewards the country will receive. REDD+ is one factor in an emergent new political conjuncture in Indonesia that is opening up to the possibilities for reworking forest governance. This thesis employs Foucault’s concept of governmentality to examine how governmental technologies are formed, contested and implemented through REDD+ and some of the early impacts the program is having (Foucault, 1991a). Drawing on grounded empirical data and inspired by a ‘not-quite neoliberal nature’ framework (de Freitas, Marston and Bakker, 2015) I show how place-based discourses, politics, actors, and interests are shaping the way REDD+ unfolds in Indonesia. This is achieved through three case studies focused on the REDD+ Taskforce; the One Map Initiative; and an Indigenous land claim in a community in Central Kalimantan. Findings from the three case studies show how current deficiencies in forestland governance have been problematized where there is no clarity over who has rights to forestland, who owns the concessions and where they are. Thus, addressing current complexities is becoming the Taskforce’s priority through series of governmental technologies including the One Map Initiative. Meanwhile, activists are making use of this opportunity to render visible Indigenous land rights in an attempt to subvert focused technical fixes to more open social justice ends. By discussing the messy actualities of developing, implementing and responding to governmental technologies the thesis problematizes pro- and anti-REDD+ debates. Rather than view REDD+ governmental technologies through “a programmer’s view” (Death, 2013) as a finished or rigid project implemented on others, I see it as an ongoing attempt to govern human – forest relationships that are shaped by contestations and resistances. Thus, the thesis makes an important contribution to neoliberal nature literature by showing that neoliberal governmental programs, such as REDD+, should be seen as sites of struggle, with different actors experiencing and engaging the program in different ways. As such, this thesis highlights how neoliberal mechanisms can be co-opted by particular actors in order to achieve diverse economic, social and environmental goals. Through engagement with governmental technologies the landscapes of forest politics change in both enabling and constraining ways.</p>
Teaching Advanced Manding Skills to Children with Autism Spectrum Disorder Using Systematic Instruction, Speech-Generating Devices, and Skinner’s Analysis of Verbal Behaviour
Authors:   , Carnett Amarie 
Published: November 2021

<p>Autism Spectrum Disorder (ASD) is characterized by marked impairments in social and communication skills, as well as restricted and/or repetitive patterns of behaviour or interests. Approximately 25-30% of children with ASD do not develop speech. As a result they may require augmentative and alternative communication (AAC) interventions. However, most interventions discussed in our present body of research focuses on basic communication skills like requesting. As such, it is important to investigate systematic teaching strategies for more complex requesting (i.e., manding) skills like requesting actions or requesting information. This research aims to extend previous manding literature by investigating effective methods for teaching advanced manding skills to children with ASD who communicate using an SGD. Three empirical intervention studies that a presented in this thesis evaluated the use of behaviour chain interruption strategy (BCIS) and systematic teaching procedures based on the principals of applied behaviour analysis (ABA), to teach advanced manding skills (i.e., manding for actions, manding for “where” questions, and persistence of “where questions”) for individuals with ASD who use speech-generating devices (SGD). Single-case research methodology was used via variations of the multiple baseline design (i.e., multiple probe multiple baseline design across participants and multiple probe multiple baseline across participants and behaviour chains) to evaluate the effectiveness of the interventions. A total of three participants (2 boys and 1 girl, ages 13, 10, and 5) participated in the interventions that were designed to teach the targeted mand. Results of each study yielded positive results, in that each participant acquired the targeted skill. Generalisation (i.e., across stimuli, over time, and across communication partners) results were mixed, however with additional teaching with the use of systematic instruction they were also acquired. Although these results are preliminary, they indicated that advanced manding skills should be taught to children with ASD who communicate using SGDs and can be acquired with the use of systematic instruction.</p>
Socioeconomic Status and Student Achievement in Primary School Mathematics: A Case Study of Two New Zealand Schools
Authors:   , Harrison Elizabeth 
Published: November 2021

<p>Existing research consistently identifies large differences in mathematics achievement between students from high and low socioeconomic status backgrounds. The link between socioeconomic status and student achievement has been repeatedly acknowledged throughout the literature, but reasons for this link are not yet fully understood. This study builds on existing international research, which identifies a large number of potential key influences for the disparity in mathematics achievement. The aim of this study was to identify which of the potentially key influences were possibly influencing student mathematics achievement in a high and a low decile New Zealand primary school, thereby suggesting ways to improve student mathematics achievement in the low decile school. Often, changes within education, including in many intervention programmes, are generic, made without identifying the specific needs of an individual school and its students. The tools developed during this research were designed to be used in schools, allowing evidence-based needs to be identified, and any changes made to be targeted at the specific needs of the school and its students. This research was conceived within a qualitative paradigm, and followed a collective case study design, focusing on two case schools, a high decile school (Pīwakawaka School), and a low decile school (Whio School). Data were collected through classroom observations, archival records, interviews, questionnaires, and physical artefacts, using tools specifically designed for this study. The data were analysed using grounded theory, allowing theories to emerge from the data. The data collected from each school were compared and two theories emerged. The first theory is that students in the high decile school appeared to be doing a greater amount of mathematics than students in the low decile school. The second theory is that students in the high decile school appeared to have more opportunities to learn new mathematics than students in the low decile school. Additionally, the findings suggested that, due to the complex nature of teaching, there was more than one key influence on student mathematics achievement contributing to each of these emergent theories. This research suggests that teachers at Whio School may be able to improve student achievement in mathematics by increasing both the amount of mathematics students interact with and the number of opportunities to learn new mathematics their students receive.</p>
Synthesis of Antimycobacterial Agents that Harness Mycothiol and Cysteine conjugate β-lyase Metabolic Pathways
Authors:   , Riordan Scott W. 
Published: November 2021

<p>Mycobacterium tuberculosis kills approximately two million people each year and is second only to HIV/AIDs in terms of death from infectious disease. The most pertinent problem in regards to Mycobacterium tuberculosis today is the increasing prevalence of drug resistant strains. Thus, there is a great need for the development of new drugs with novel targets. This thesis aimed to address this problem by synthesizing a compound that could exploit the mycothiol detoxification pathway, unique to Mycobacterium, in order to cause cell death, through the release of a harmful halothioketene. The research described herein involved the successful synthesis of the desired mycothiol analogue, along with three other related compounds. The target compounds were synthesised via protection of N-acetyl glucosamine, followed by thioglycosidation with cyclohexane thiol. Subsequent deprotection and coupling to Boc protected Strichlorovinyl cysteine provided access to the synthetic target and its β-anomer, as well as their Boc protected precursors. The original synthetic target demonstrated weak antimycobacterial activity against Mycobacterium smegmatis and an encouraging sub 100 μM MIC against Mycobacterium bovis derived Bacillus Calmette–Guérin. Unexpectedly the beta anomer of the synthetic target also displayed antimycobacterial activity against Bacillus Calmette–Guérin (MIC 125 - 250 μM). All compounds proved to be active against HL60 cells (16-114 μM). Whilst further work is required to improve efficacy, the work presented here demonstrates the potential of these compounds as leads for the generation of new antimycobacterial agents.</p>
Learning from the Artist: Theory and Practice of Example-Based Character Deformation
Authors:   , Lewis John 
Published: November 2021

<p>Movie and game production is very laborious, frequently involving hundreds of person-years for a single project. At present this work is difficult to fully automate, since it involves subjective and artistic judgments. Broadly speaking, in this thesis we explore an approach that works with the artist, accelerating their work without attempting to replace them. More specifically, we describe an “example-based” approach, in which artists provide examples of the desired shapes of the character, and the results gradually improve as more examples are given. Since a character’s skin shape deforms as the pose or expression changes, or particular problem will be termed character deformation. The overall goal of this thesis is to contribute a complete investigation and development of an example-based approach to character deformation. A central observation guiding this research is that character animation can be formulated as a high-dimensional problem, rather than the two- or three-dimensional viewpoint that is commonly adopted in computer graphics. A second observation guiding our inquiry is that statistical learning concepts are relevant. We show that example-based character animation algorithms can be informed, developed, and improved using these observations. This thesis provides definitive surveys of example-based facial and body skin deformation. This thesis analyzes the two leading families of example-based character deformation algorithms from the point of view of statistical regression. In doing so we show that a wide variety of existing tools in machine learning are applicable to our problem. We also identify several techniques that are not suitable due to the nature of the training data, and the high-dimensional nature of this regression problem. We evaluate the design decisions underlying these example-based algorithms, thus providing the groundwork for a ”best practice” choice of specific algorithms. This thesis develops several new algorithms for accelerating example-based facial animation. The first algorithm allows unspecified degrees of freedom to be automatically determined based on the style of previous, completed animations. A second algorithm allows rapid editing and control of the process of transferring motion capture of a human actor to a computer graphics character. The thesis identifies and develops several unpublished relations between the underlying mathematical techniques. Lastly, the thesis provides novel tutorial derivations of several mathematical concepts, using only the linear algebra tools that are likely to be familiar to experts in computer graphics. Portions of the research in this thesis have been published in eight papers, with two appearing in premier forums in the field.</p>
Improving the Performance of Cloud-based Scientific Services
Authors:   , Chard Ryan 
Published: November 2021

<p>Cloud computing provides access to a large scale set of readily available computing resources at the click of a button. The cloud paradigm has commoditised computing capacity and is often touted as a low-cost model for executing and scaling applications. However, there are significant technical challenges associated with selecting, acquiring, configuring, and managing cloud resources which can restrict the efficient utilisation of cloud capabilities. Scientific computing is increasingly hosted on cloud infrastructure—in which scientific capabilities are delivered to the broad scientific community via Internet-accessible services. This migration from on-premise to on-demand cloud infrastructure is motivated by the sporadic usage patterns of scientific workloads and the associated potential cost savings without the need to purchase, operate, and manage compute infrastructure—a task that few scientific users are trained to perform. However, cloud platforms are not an automatic solution. Their flexibility is derived from an enormous number of services and configuration options, which in turn result in significant complexity for the user. In fact, naïve cloud usage can result in poor performance and excessive costs, which are then directly passed on to researchers. This thesis presents methods for developing efficient cloud-based scientific services. Three real-world scientific services are analysed and a set of common requirements are derived. To address these requirements, this thesis explores automated and scalable methods for inferring network performance, considers various trade-offs (e.g., cost and performance) when provisioning instances, and profiles application performance, all in heterogeneous and dynamic cloud environments. Specifically, network tomography provides the mechanisms to infer network performance in dynamic and opaque cloud networks; cost-aware automated provisioning approaches enable services to consider, in real-time, various trade-offs such as cost, performance, and reliability; and automated application profiling allows a huge search space of applications, instance types, and configurations to be analysed to determine resource requirements and application performance. Finally, these contributions are integrated into an extensible and modular cloud provisioning and resource management service called SCRIMP. Cloud-based scientific applications and services can subscribe to SCRIMP to outsource their provisioning, usage, and management of cloud infrastructures. Collectively, the approaches presented in this thesis are shown to provide order of magnitude cost savings and significant performance improvement when employed by production scientific services.</p>
