Optimising the Massive MIMO Downlink in the Presence of Power Amplifier Nonlinearities
Authors:   , Humphrey Peter 
Published: December 2021

<p>Massive MIMO is known for its high level of spectral efficiency in multipath rich environments. We present a detailed Massive MIMO cell system using maximum-ratio transmission (MRT) and zero-forcing (ZF) where energy efficiency is taken into account. This is done through the use of a realistic model of moderate performance and hence moderate cost power amplifiers (PAs) for the base station downlink, which could be applied in a practical Massive MIMO system. In the process of detailing the linear aspects of the Massive MIMO system, results for the normalisation factor and array gain are derived, which as far as the author is aware are original. These results are used to derive an expression to optimise the downlink signal-to-interference-and-noise-ratio (SINR) in a linear system, which is also original as far as the author is aware. A process is outlined to optimise the downlink SINR when nonlinear PAs are used and a simulation of a cell system is performed where the benefits of applying the nonlinear optimisation process are demonstrated.</p>
Continuity of Midwifery Care in Complexity
Authors:   , Martin Eleanor 
Published: December 2021

<p>Continuity of midwifery care has demonstrated some beneficial outcomes for mothers and their babies with no evidence of poorer outcomes. Much of the evidence to support this claim is sourced from research conducted with women described as ‘low risk’. The model of midwifery in New Zealand, which is based on continuity of midwifery carer, has the potential for midwives to continue care even when significant risk has been identified. This care would be provided in collaboration with and support from medical personnel and hospital-based midwives. There is no research that has specifically examined the outcomes for women with complex needs, also called ‘high risk’, who have been provided continuity of midwifery carer. Given the increased incidence of morbidity in the childbearing population it is important to examine this issue in some depth. This small piece of research begins this, by looking at how women with complex needs and who have had continuity of midwifery care have experienced this care. The aim of this research therefore is to provide a comprehensive description of how women with complexities experience continuity of midwifery care across the maternity episode. A qualitative descriptive study was conducted in one part of New Zealand. Three women, all with varying types of complexity were interviewed. The interviews were transcribed, and the transcripts were analysed thematically. There were four themes: the relationship was everything; knowing what was happening was important; power was managed and balanced; and extra care was needed. The three women had the same needs and experiences of continuity as did low risk women described in the literature. However, another aspect, not previously reported, was that the women thought that the midwives spent a lot more time with them than they otherwise would have needed to. They were grateful for this.</p>
Orbital Habitability: Architectural Design for Extra-Terrestrial Habitation
Authors:   , Tozer Griffin 
Published: December 2021

<p>Companies like SpaceX and Virgin Galactic are privatising the space industry. This privatisation will allow more and more people to inhabit space for more extended periods, with less training than prior astronauts. Space habitation brings with it a vast array of issues, which significantly limit the designs that are possible in orbit. This thesis explores how the challenges of inhabiting outer space can be mitigated through architectural design. The theoretical basis for this exploration is research into habitability. Habitability is how conducive an environment is to living and working. This is crucial to understanding the risks of inhabiting environments in orbit and how these can be challenged through design. The Framework for this exploration’s site and program is asteroid mining. Asteroid mining is an exciting possibility for the next stage of human presence in space. Utilising asteroid resources could greatly aid in establishing orbital infrastructure around the Earth and allowing us to travel even further. As a framework, this defines a tighter scope than looking at space habitation in general and allows this thesis to dive deeper into the finer details of habitability for a specific group of people. The aim of this thesis is to demonstrate designed solutions to issues of habitability within the constraints necessary to construct a space station. This thesis considers how a design might be; designed and modelled, deployed in space, constructed, and most fundamentally, how it could mitigate the psychological and physiological issues of long-term space habitation. This is accomplished through a research-led design process centred on self-evaluation through the habitability principles defined in this thesis. This thesis fundamentally collates and builds upon our existing knowledge of space habitation and presents one possibility for the future of space habitation. This is merely one small step for the furthering of human habitability in space.</p>
Vulnerable Territories: The Perpetually Shifting Edge
Authors:   , Wellwood Joseph 
Published: December 2021

<p>New Zealand’s coastline is rapidly receding. The increased threat of rising sea levels continues to erode the shore line causing extensive and irreparable damage to thousands of coastal properties, often dismantling communities and the kiwi dream of living near the ocean. With global temperatures continuing to rise, all of our coastal communities are at risk. The current measure of response to this issue is through managed retreat, the removal and relocation of all ‘at risk’ buildings in coastal hazard zones. While this approach is successful in preserving the physical structures, it remains an undesirable solution that forces homeowners to abandon their community and the coastline for the safety of higher ground. The retreat is hampered among debate within the effected regions as the forced detachment of long standing communities often results in the loss of ‘sense of place’ that living within a coastal community enables. This thesis proposes that Haumoana in Hawkes Bay offers the fitting location to introduce an alternative coastal community model that actively responds to the impending hazards whilst retaining the societal poetics. Situated just south of the nearby communities of Te Awanga and Haumoana, two of the most at-risk coastal regions in New Zealand that are currently facing the prospect of dismantlement. The site was specifically chosen due to the fact that erosion is predicted to diminish half its usable land over the next century, this thesis will investigate the potential risks to the respective coastline, the role that this would play in an adaptive community, and the possible design options that can respond and enhance a future sustainable landscape. This thesis argues that a coastal community can be designed to actively adapt and respond to the threat of erosion rather than being dismantled through retreat; that by adopting design principles that protect the land on which they are placed, the coastal hazards of the region can be lessened; and that an adaptive community model can be achieved whilst retaining the ‘sense of place’ that coastal community’s exhibit. The thesis proposes that this can be achieved by incorporating and reinforcing natural features of the coast into the architectural design at various scales; accommodating for, and adapting to the imminent threat of erosion; and by invoking principles of sustainable design in company with adaptive planning and resilient design, thereby pushing the standards of coastal planning beyond typical practice.</p>
Stratigraphic development and petroleum prospectivity of northern Zealandia
Authors:   , Dos Santos Zelia 
Published: December 2021

<p>Northern Zealandia lies between Australia, New Zealandia, and New Caledonia. It has an area of 3,000,000 km2 and is made up of bathymetric rises and troughs with typical water depths of 1000 to 4000 m. I use 39,309 line km of seismic-reflection profiles tied to recent International Ocean Discovery Program (IODP) drilling and three boreholes near the coast of New Zealand to investigate stratigraphic architecture and assess the petroleum prospectivity of northern Zealandia. Sparse sampling requires that stratigraphic and petroleum prospectivity inferences are drawn from better-known basins in New Zealand, Australia, New Caledonia, TimorLeste and Papua New Guinea. Five existing seismic-stratigraphic units are reviewed. Zealandia Seismic Unit U3 is sampled near New Zealand and may contain Jurassic Muhiriku Group coals. Elsewhere, Seismic Unit 3 may have oil-prone equivalents of the Jurassic Walloon Coal Measure in eastern Australia; or may contain Triassic-Jurassic marine source rocks, as found in offshore Bonaparte Basin, onshore Timor-Leste, and the Papuan Basin in Papua New Guinea. Seismic Unit U2b (Mid-Cretaceous) is syn-rift and may contain coal measures, as found in Taranaki-Aotea Basin and New Caledonia. Seismic Unit U2a (Late Cretaceous to Eocene) contains coaly source rocks in the southeastern part of the study area, and may also contain marine equivalent carbonaceous mudstone, as found at Site IODP U1509. Unit U2a is transgressive, with coaly source rocks and reservoir sandstones near its base, and clay, marl and chalk above that provides a regional seal. Seismic Unit U1b (Eocene-Oligocene) is mass-transport complexes and basin floor fans related to a brief phase of convergent deformation that created folds in the southern part of the study area and regionally uplifted ridges to create new sediment source areas. Basin floor fans may contain reservoir rock and Eocene folding created structural traps. Seismic Unit U1a is Oligocene and Neogene chalk, calcareous ooze, and marl that represents overburden. Mass accumulation rates (MAR) and climatic temperatures were high in the late Miocene and early Pliocene, resulting in peak thermal maturity and hydrocarbon expulsion at ~ 3 Ma. Approximately one-fifth of the region has adequate source rock maturity for petroleum expulsion at the base of Seismic Unit U2: Fairway Basin (FWAY), southern New Caledonia Trough (NCTS) and Reinga Basin (REIN). Plays may exist in either Seismic Unit U3 or U2, with many plausible reservoir-seal combinations, and several possible trapping mechanisms: unconformities, normal faults, folds, or stratigraphic pinch-out. The rest of the region could be prospective, but requires a source rock to exist within Seismic Unit U3, which is mostly unsampled and remains poorly understood.</p>
Exploring the role of schizotypy in creative cognition
Authors:   , Hedley Sophie 
Published: December 2021

<p>Creativity is hugely important in our everyday lives. Understanding what makes some people more creative than others is not just important in traditional creative fields. Creative problem solving is the key to solving all significant challenges we face as a society, including but not limited to technological, political and environmental challenges. Mental illness, in both popular culture and in psychological science, have long been linked to creative thought. Many eminent creatives, both past and current, attribute their success to their mental illness. For example, in schizophrenia, the grandiose thinking and florid hallucinations that characterise this disorder may be supportive of creative thinking. However, schizophrenia is characterised by severe cognitive deficits that, according to models of creativity, would be disadvantageous to creative thinking. Schizotypy is a personality trait that is characterised by some features of schizophrenia (unusual thinking, poor interpersonal communication), but is not accompanied by the same severe cognitive deficits seen in schizophrenia. Based on this view, it is reasonable to assume that people high on schizotypal traits may be more creative than those who are low on schizotypal traits. While there a number of studies examining this relationship, findings are inconsistent, with effect sizes ranging from -.42 to .8. In my thesis, I explored a) whether there was a relationship between schizotypy and creativity and b) whether that relationship could be explained by underlying differences in cognitive processing (associative processing and executive control). I predicted that positive schizotypy in particular (typified by unusual thinking, superstitious beliefs) would be positively correlated with schizotypy in three different measures of creativity (two performance based tasks and one self-report measure) in two different samples of participants. In Chapters 3 + 4, I tested the relationship between schizotypy and creativity using two different methods. In chapter 3, I found no evidence for the predicted effect. In fact, I found a negative association between positive schizotypy and scores on one measure of creativity (the Remote Associates test) and a positive association between negative schizotypy (characterised by interpersonal deficits) and performance on the RAT. These effects did not replicate in the second sample. Finally, there was a positive association between disorganised schizotypy and creativity on the Alternate Uses task. The results of Chapter 4, using a latent profile analytic approach, mirrored the results of Chapter 3. Finally, Chapter 5 found no support for any relationship being mediated by associative processing or executive control; however, there was partial support for two models of creativity. Overall, evidence suggests that schizotypal traits are not helpful for creativity. These results shed light on some of the challenges when conducting research regarding both schizotypy and creativity.</p>
Building Information Modelling: An analysis of the methods used to streamline design-to-construction in New Zealand
Authors:   , Chan Nelson 
Published: December 2021

<p>The following study explores and investigates the current methods New Zealand (NZ) Architectural, Engineering and Construction (AEC) firms use to enable effective BIM coordination in their projects. The purpose was to gain and contribute knowledge of the various methods for successful BIM delivery, as well, as to bridge the gap between academia and industry for a greater understanding of BIM use in an NZ context. A qualitative research approach was carried out and comprised of semi-structured interviews in which eight industry participants across the design-to-construction supply chain were selected and interviewed. From the results, the different methods identified were: BIM-to-fabrication; change of procurement methods; and incorporating BIM Collaboration Format (BCF) plugin platforms. These methods identified contribute to knowledge for future researchers to undertake; predominantly to provide direction and recommendations to explore each method in an NZ industry context further. Further discussions of the results identify that although the different methods can contribute to better BIM coordination, the success of a BIM model to be delivered effectively is dependent on two significant factors. The factors are; firstly, to capture the BIM requirements and needs of the client to establish well-defined deliverables in the BEP; and secondly, to ensure that the project team are to understand their role and responsibilities right throughout the project. This was a crucial finding in this thesis as although the methods are effective in enabling greater BIM coordination; ultimately it comes down to BIM understanding and expertise from key project stakeholders; which brings the notion of the issue back to the root of the problem. Other key findings from this thesis indicate a positive future for BIM within the NZ AEC industry, with many of the participant firms recognised to be proactive and open to incorporating BIM into their projects. Though the signs are encouraging, discussions with industry participants still express their concerns on needing to align the understanding of BIM between key project stakeholders. Therefore, an education piece which focuses on the client and their understanding of BIM in an NZ context is suggested for future research. This thesis also presents academia with valuable industry BIM workflow diagrams which the author has either illustrated or been provided by participants.</p>
Accessibility in Aotearoa: A Mixed-Methods Study of Low-Emissions Transport Demand in the Greater Wellington Region
Authors:   , Petredean Han Ling 
Published: December 2021

<p>Like many nations, Aotearoa New Zealand’s land-use and transport development has prioritised planning for mobility, movement, over accessibility, access. This has contributed to an auto-centric transportation system and a high national road emissions profile. In light of the imminent threat of catastrophic climate change, a low-emissions transport sector transition is needed. Understanding how and why people travel is a critical prerequisite for achieving this shift. Planners and policymakers increasingly recognise that transport demand is fundamentally influenced by the desire for access over movement. An accessibility-based framework aligns with this interpretation and supports analysing personal and contextual drivers of transport demand. Policymakers tasked with promoting a low-emissions transport sector transition are seeking to identify existing low-emissions transport uptake constraints and potential avenues for their improvement. Using a mixed-methods approach, this thesis addresses an existing gap in the literature by analysing low-emissions transport demand in the Greater Wellington Region (GWR), informed by an accessibility-based framework. Survey responses supplied quantitative data on user-based needs, abilities, and attitudes towards GWR low-emissions transport options. Practicality – the degree to which a transport option facilitates access in reasonable time, at reasonable cost, and with reasonable ease – was found to be the strongest predictor of ability to use low-emissions transport. Qualitative data was also collated from stakeholders knowledgeable of transport policy and planning at the local, regional, and central government level. This provided insight into GWR low-emissions transport supply and oversight, as well as the impact of land-use policies, transport policy and funding structures, and governance agendas and capabilities. These findings support augmenting low-emissions transport with an accessibility orientation, but also reveal the challenges of doing so within current governance structures.</p>
Beyond the Rhetoric of Participation: A Case Study of Participatory Practices and Power in East Nusa Tenggara, Indonesia
Authors:   , Ecclestone Cynthia 
Published: December 2021

<p>This study looks critically at the practices of participatory development by a local NGO in East Nusa Tenggara, Indonesia. In doing so, the Life Skills Training programme is chosen as a case study of potentially participatory development. By exploring people’s experiences, perceptions, and feelings about their participation, the study examines the power dynamics in the programme. To gather data, the study used semi-structured interviews and observations. Interviews were conducted with 14 research participants, who were purposively selected from different backgrounds. The study finds that the approaches of the programme point to lower-level forms of participation, with local people having both minimal involvement and little role in decision-making. Despite the use of the rhetoric of participation, doubts about the quality of participation are raised particularly in relation to gender, age, and religious differences. By scrutinising the ways in which issues of power manifest in the programme, the study demonstrates that issues of power and power relations in participatory development are quite complex. Using the frameworks of power analysis, I argue that issues related to inequalities of power are manifested in the NGO’s domination of decision-making processes, and that these issues were also contributed to by a patriarchal culture and filial piety. More importantly, I argue that people’s participation in the programme is less likely lead to meaningful outcomes if the issues of power imbalances are not addressed. The study provides useful insights into ways to improve the practices of participatory development. An increased understanding of various forms of power and their implications will be useful for development practitioners to exercise their power to make a difference. Moreover, efforts to reduce power imbalances in participatory development will be inadequate without critically examining and attending to power and its dynamics. Without a deeper understanding of power, development programmes that make claims about participation may be less effective in achieving transformative goals for the intended beneficiaries.</p>
Upcycling Wild Pigeon's Field in a post-hydrocarbon Brunei - An Exploration of Architecture Reacting to Social Changes Through Narratives
Authors:   , Piw Pg Dr Hj Ismail Ak Hj Saifulnizam 
Published: December 2021

<p>The hydrocarbon industry has immensely influenced and moulded the societal structure of the inhabitants of modern day Brunei. Nonetheless, the dependency on this commodity will eventually cease, shifting the future social structure and leaving questions on plausible resolutions towards treatments on the existing sites, ‘non-buildings’ and infrastructures of the industry. Infrastructures and ‘non-buildings’ are typically subjected to the process of dismantling, removal, deep sea dumping and abandonment. It has been observed that in recent times, alternate methods are offered within the architectural profession. Through the application of adaptive reuse architecture, warehouses, factories and even ‘non-building’ are repurposed, where its industrial heritage and cultural value are highly recognised and considered necessary to retain. Focusing on specified onshore oilfields in Brunei, this thesis seeks an exploration into a methodology of regenerating a site and offering spaces that evoke a ‘sense of belonging’ or cultural identity. Through architectural discourse on memory and semiotics, local narratives are put forward and explored as an extension to cultural identity. This methodology is further explored through the application of John Hejduk’s concept of languages and masques. It proposes an imaginative practise into visual experiments for an exploration on the effect of reusing hydrocarbon infrastructure as architectural spaces. As Brunei shifts towards a new epoch, studies on current socioeconomic structure are critical to recognise where the structure is leaning towards to as it cannot simply change overnight.</p>
