'Of Red War and Little Else': European Responses to Indigenous Violence in the Tasman World, c.1769-1850s
Authors:   , Ritchie Samuel Gordon Gardiner 
Published: November 2021

<p>Europeans responded to indigenous internecine violence in a variety of ways in the Tasman world from first contact to the middle of the nineteenth century. Whereas extant historiography has previously addressed European responses to Māori and Aboriginal violence in geographic and temporal isolation, a comparison spanning time and space augments knowledge of these responses. Violence was not the only aspect of indigenous societies Europeans responded to, nor was indigenous violence the only justification for colonisation. However an investigation of the ways in which Europeans represented and responded to indigenous violence enables a better understanding of the processes of the colonisation of the Tasman world. Indigenous internecine violence included cannibalism, infanticide, inter-gender violence, and inter-tribal warfare. Through a wide variety of European observations of this violence, this thesis identifies an initial conceptualisation of both New Zealand Māori and Aboriginal peoples of Australia as violent, cannibal ‘savages’. This conceptualisation was used to justify both colonisation and the related evangelical and colonial administrative attempts to suppress indigenous violence, as internecine violence was deemed ‘un-civilised’, unchristian, and unacceptable. Europeans attempted to suppress indigenous violence as it was seen both as an impediment to colonisation and, relatedly, as an inhibitor to the ‘redemption’ of indigenous peoples. While indigenous violence was seen as a barrier to colonisation, however, it was also simultaneously used to promote colonisation. Thus the attempted suppression of indigenous violence developed into the European mobilisation and utilisation of intra-Māori and intra-Aboriginal violence in the promotion of colonisation. The development of European responses to indigenous internecine violence – from conceptualisations, through attempted suppression, to utilisation – is here examined in a Tasman-world context, drawing upon the interactions between these varied responses. In tracing this development within a comparative framework, both indigenous agency and a rejection of the historiographically persistent notions of a homogenous (and harmonious) Aboriginal Australia and a homogenous Māori people during this time period are key threads.</p>
Seismic Anisotropy and Stress of the Canterbury Plains
Authors:   , Holt Rob 
Published: November 2021

<p>The Mѡ=7.1 Darfield (Canterbury) earthquake struck on 4 September 2010, approximately 45 km west of Christchurch, New Zealand. It revealed a previously unknown fault (the Greendale fault) and caused billions of dollars of damage due to high peak ground velocities and extensive liquefaction. It also triggered the Mw=6.3 Christchurch earthquake on 22 February 2011, which caused further damage and the loss of 185 lives. The objective of this research was to determine the relationship between stress and seismic properties in a seismically active region using manually-picked P and S wave arrival times from the aftershock sequence between 8 September 2010-13 January 2011 to estimate shear-wave splitting (SWS) parameters, VP =VS-ratios, anisotropy (delay-time tomography), focal mechanisms, and tectonic stress on the Canterbury plains. The maximum horizontal stress direction was highly consistent in the plains, with an average value of SHmax=116 18 . However, the estimates showed variation in SHmax near the fault, with one estimate rotating by as much as 30° counter-clockwise. This suggests heterogeneity of stress at the fault, though the cause remains unclear. Orientations of the principal stresses predominantly indicate a strike-slip regime, but there are possible thrust regimes to the west and north/east of the fault. The SWS fast directions (ø) on the plains show alignment with SHmax at the majority of stations, indicating stress controlled anisotropy. However, structural effects appear more dominant in the neighbouring regions of the Southern Alps and Banks Peninsula.</p>
Reggaenomics: The Relationship Between Copyright Law and Development in the Jamaican Music Industry
Authors:   , Taylor Sharma Latoya 
Published: November 2021

<p>One argument posits that copyright is necessary for incentivising creative expressions. To what extent does this hold true for individual copyright-based sectors in a developing nation’s economy? Although Jamaica’s Copyright Act 1993 complies with the major copyright treaties, little is known about whether (and how) the copyright regime allows the Jamaican music industry to foster national development. Accordingly, the focus of this thesis is to examine the developmental impact of the copyright system on the Jamaican music industry. This thesis traces the evolution of the local music industry and its complex interaction with copyright law. This research assesses the various approaches to economic development and highlights the limitations of a collective management-based approach and weaknesses in the individual rights management model. It also analyses the compatibility between a human development approach to copyright and the theoretical justifications for copyright. It points out substantive areas of the domestic copyright legislation that could be reformed in order to improve the statute’s applicability to the music industry insofar as development is concerned. This thesis adopts a qualitative methodological approach and uses interviews from 57 music industry participants. The findings suggest that societal context is as important as the legal rights, in giving copyright owners incentives to create. Historical, political, socio-cultural, economic and institutional factors play a key role in shaping stakeholders’ treatment of copyright. Music industry players’ experiences can help inform policymaking by fostering a better understanding of the implications of copyright protection for this vital sector of the economy.</p>
Matroids, Complexity and Computation
Authors:   , Snook Michael 
Published: November 2021

<p>The node deletion problem on graphs is: given a graph and integer k, can we delete no more than k vertices to obtain a graph that satisfies some property π. Yannakakis showed that this problem is NP-complete for an infinite family of well- defined properties. The edge deletion problem and matroid deletion problem are similar problems where given a graph or matroid respectively, we are asked if we can delete no more than k edges/elements to obtain a graph/matroid that satisfies a property π. We show that these problems are NP-hard for similar well-defined infinite families of properties. In 1991 Vertigan showed that it is #P-complete to count the number of bases of a representable matroid over any fixed field. However no publication has been produced. We consider this problem and show that it is #P-complete to count the number of bases of matroids representable over any infinite fixed field or finite fields of a fixed characteristic. There are many different ways of describing a matroid. Not all of these are polynomially equivalent. That is, given one description of a matroid, we cannot create another description for the same matroid in time polynomial in the size of the first description. Due to this, the complexity of matroid problems can vary greatly depending on the method of description used. Given one description a problem might be in P while another description gives an NP-complete problem. Based on these interactions between descriptions, we create and study the hierarchy of all matroid descriptions and generalize this to all descriptions of countable objects.</p>
The Consistency of Repeated Witness Testimony Leads Triers-of-Fact to Over-Rely on the Power of a Single Voice
Authors:   , Foster Jeffrey L. 
Published: November 2021

<p>Are claims more credible when made by multiple people, or is it the repetition of claims that matters? Some research suggests that claims have more credibility when independent sources make them. Yet, other research suggests that simply repeating information makes it more accessible and encourages reliance on automatic processes—factors known to change people’s judgments. In Experiment 1, subjects took part in a “misinformation” study: Subjects first watched a video of a crime and later read witness reports attributed to one or three different witnesses who made misleading claims in either one report or repeated the same misleading claims across all three reports. In Experiment 2, subjects who had not seen any videos read those same reports and indicated how confident they were that each claim happened in the original event. Subjects were more misled by—and more confident about—claims that were repeated, regardless of how many witnesses made them. These findings led us to hypothesize that the repeated claims of a single witness are seen as consistent, while the claims of multiple witnesses are seen as having consensus. We tested this hypothesis in Experiments 3 and 4 by asking subjects who had not seen the video to read the reports that repeated the claims. In Experiment 3, half of the subjects read reports that contained some peripheral inconsistencies. In Experiment 4 all subjects read reports that contained inconsistencies, but half of the subjects were warned about the accuracy of the inconsistent reports. Later, everyone indicated how confident they were that each claim really happened. Warning subjects about the inconsistent reports (Experiment 4) led them to rate the repeated claims of a single witness—but not multiple witnesses—as less credible; A finding consistent with our hypothesis. In Experiment 5, we tested an alternative explanation that a failure to attend to the source of the information may explain our findings by asking half of the subjects to complete a source monitoring component with their confidence test. We failed to find evidence for this explanation. We conclude that subjects interpreted both the consistency of a single witness's repeated claims, and the consensus among multiple witnesses' converging claims, as markers of accuracy. Importantly, warning subjects about the accuracy of the inconsistent reports reduced subjects’ confidence in the claims made by a single witness, but not multiple witnesses. These findings fit with research showing that repeating information makes it seem more true, and highlight the power of a single repeated voice.</p>
Genetic Management of Wild and Translocated Black Rhinoceros in South Africa’s KwaZulu-Natal Region
Authors:   , Anderson-Lederer Rosalynn Marie 
Published: November 2021

<p>The African black rhinoceros (Diceros bicornis) is critically endangered. Like other megafauna, the species is managed in parks and is often translocated to expand their range into reserves where they have been extirpated. Management of genetic variation has been identified as an important consideration in long-term management plans for many wild and captive endangered species including black rhino. In this thesis I examined the contemporary levels of genetic variation within the black rhinoceros (D. b. minor) in KwaZulu-Natal (KZN), South Africa, and specifically the relict source population at Hluhluwe-iMfolozi Game Reserve (HiP), and how this information can be incorporated into management decisions to improve the long-term viability and persistence of the population. Previous studies have examined levels of genetic variation and differentiation among the three black rhino subspecies (D. b. minor, D. b. michaeli and D. b. bicornis) in an attempt to resolve their taxonomy and to establish baseline genetic assessments for managing populations. However, there has been a lack of genetic information based on the variable mitochondrial DNA (mtDNA) control region of the KZN metapopulation and a direct comparison of microsatellite variability between the D. b. minor populations of KZN and Zimbabwe. The specific objectives of this study were to: (1) determine the DNA sequence of the mtDNA control region of three subspecies and estimate the level of variation within the HiP source and KZN metapopulation and compare the results with D. b. minor outside KZN and the other two subspecies; (2) use ten microsatellite DNA markers to estimate the levels of heterozygosity and allelic diversity in the HiP source and KZN metapopulation and compare results to previously published microsatellite data (specifically native Zimbabwe D. b. minor; and (3) use VORTEX Population Viability Analysis (PVA) and HiP vital rates to model the effects of increasing population size and supplementation, and investigate what management scenarios would be most effective for minimizing the loss of genetic variation caused by genetic drift with HiP...</p>
DUPLICATE DO NOT PUBLISH - Tubular Daylighting Devices and People: A comparison of the human responses to Tubular Daylighting Devices and fluorescent lighting
Authors:   , Sullivan James 
Published: November 2021

<p>Tubular Daylighting Devices are used to bring daylight into deep-plan spaces, and meet sustainability goals. However, they are expensive, and justification for their use lies in hypothesised benefits they can provide in areas such as well-being and productivity. Yet, there is very little research into the effects of Tubular Daylighting Devices. The broader daylighting literature suggests that benefits to satisfaction, mood, and performance are possible — though research into the benefits of daylight is still not conclusive. Therefore, a before and after study was carried out in a windowless computer room in the university to compare how the students responded under TDDs versus typical electric lighting. Their cognitive performance, change in mood, average sleepiness, and perceptions of the room and lighting were measured. TDDs significantly increased ratings of room attractiveness and brightness, and had no more perceived glare than the electric lighting. Ratings of lighting quality were on a par with both typical electric lighting and good modern lighting. They were also just as effective on overcast days as sunny. No effects were found on performance or sleepiness, and mood results were inconclusive. Overall, it is suggested that TDDs can be considered to be on a par with good modern lighting, and superior to typical existing lighting. Note, however, that it is possible that effects in rooms with windows could differ from those found here. Further research should use longer exposures and larger sample sizes if they wish to find performance effects.</p>
Algorithm and design improvements for indirect time of flight range imaging cameras
Authors:   , Drayton Benjamin Mark Moffat 
Published: November 2021

<p>This thesis describes the development of a compact and modularised indirect time of flight range imaging camera. These cameras commonly use the Amplitude Modulated Continuous Wave (AMCW) technique. For this technique, an entire scene is illuminated with light modulated at a high frequency. An image sensor is also modulated and the phase shift introduced between the two modulation signals, due to the transit time of the light reflecting off objects in the scene and returning to the camera, is used to measure the distance. The system constructed for this thesis is controlled by a Cyclone III FPGA and is capable of producing full field of view range images in real time with no additional computational resources. A PMD19K-2 sensor is used as the modulatable image sensor, and is capable of modulation frequencies up to 40 MHz. One significant issue identified with this range imaging technology is that the precision of the range measurements are often dependent on the properties of the object being measured. The dynamic range of the camera is therefore very important when imaging high contrast scenes. Variable Frame Rate Imaging is a novel technique that is developed as part of this thesis and is shown to have promise for addressing this issue. Traditional theory for indirect time of flight cameras is expanded to describe this technique and is experimentally verified. A comparison is made between this technique and traditional High Dynamic Range Imaging. Furthermore, this technique is extended to provide a constant precision measurement of a scene, regardless of the properties of the objects in the scene. It is shown that the replacement of the standard phase detection algorithm with a different algorithm can both reduce the linearity error in the phase measurements caused by harmonics in the correlation waveform and ameliorate axial motion error caused by relative motion of the camera and the object being measured. The new algorithm requires a trivial increase in computational power over the standard algorithm and can be implemented without any significant changes to the standard hardware used in indirect time of flight cameras. Finally, the complete system is evaluated in a number of real world scenarios. Applications in both 3D modelling and mobile robotics are demonstrated and tests are performed for a variety of scenarios including dynamic scenes using a Pioneer 2 robot.</p>
Gender Equality – A Feel Good Norm?: Divergence between Rhetoric and Practice in the EU's Development Policy towards the Pacific Islands
Authors:   , Schnellecke Katia 
Published: November 2021

<p>As one of the world’s largest donors, the European Union provides development assistance to the Pacific Island Countries. At the same time, the EU actively promotes its own values and principles toward the Island Countries as part of the development cooperation with the region. In taking on the role of a norm promoter, the EU promotes its core values in the Pacific region such as democracy, good governance, the rule of law, and also gender equality. The Union is committed the promotion of equal treatment and equal opportunities for women and men. The norm is emphasised and promoted in all development strategies for the Pacific region and in the agreements with the Island countries. But how committed is the EU to gender equality when it comes to the active promotion of the norm in the development projects for the Pacific Islands? This thesis investigates the divergence between the EU’s rhetoric and practice when it comes to the promotion of gender equality in its development policy towards the Pacific region. An analysis of the Union’s rhetoric promotion of gender equality and practical support of the norm in the development projects for the Pacific region provides clear evidence for a gap between the EU’s intentions and reality. Whereas the norm is actively promoted throughout the EU’s strategies and agreements with the Pacific region, gender equality is neglected in the plans for most of the development projects. This thesis argues that the successful promotion of gender equality is hindered by internal and external barriers as well as the EU’s fragmented composition into different units and actors, that pursue a policies based on norms as well as for interest-related reasons. The identified divergence between the EU’s intentions and reality has a crucial impact on its role as a norm promoter: it undermines its power as a normative actor and its legitimacy to shape the concept of normal.</p>
From Users to Choosers: the Change in Employee Technology Expectations
Authors:   , Clarke David J 
Published: November 2021

<p>This research looks at the motivation for using non-sanctioned technologies within a business context; that is, using Information Technology (IT) systems other than those provided (or approved) by the IT department. In this research, the non-sanctioned IT systems of primary interest are the internet based applications, but also includes personally owned hardware devices such as laptops, tablets and smartphones. This qualitative study used the key informant approach to gain an understanding of the subject using a semi-structured interview format. The results show that employees in knowledge based roles are choosing their own technology tools when they believe that they give them better functionality or flexibility over those offered and approved by the traditional IT department. Graduates and other millennial employees are found to be using non-sanctioned systems more frequently than older workers; millennials are also far more likely to use whatever application or device they want, regardless of the source or what corporate IT policies stated. The use of these non-sanctioned technologies should be a source concern to IT management because many of these can circumvent the organisations security and data management governance policies, giving the potential for data loss or unwanted exposure, regulatory compliance failure or have undesirable legal implications. The results also suggest that IT departments do not have the resources to keep up with the rate of change in technology. At the same time, the users of their services are able to obtain technology solutions from a range of other sources. This may mean a change in the role of the IT department as it loses its position as the technology gatekeeper.</p>
Ion-size effects on cuprate High Temperature Superconductors
Authors:   , Mallett Benjamin Patrick Pennington 
Published: November 2021

<p>The cuprates are a family of strongly electronically-correlated materials which exhibit high-temperature superconductivity. There has been a vast amount of research into the cuprates since their discovery in 1986, yet despite this research effort, the origins of their electronic phases are not completely understood. In this thesis we focus on a little known paradox to progress our understanding of the physics of these materials. There are two general ways to compress the cuprates, by external pressure or by internal pressure as induced by isovalent-ion substitution. Paradoxically, they have the opposite effect on the superconducting transition temperature. This thesis seeks to understand the salient difference between these two pressures. We study three families of cuprates where the ion size can be systematically altered; Bi₂(Sr₁.₆₋xAx)Ln₀.₄CuO₆₊δ, ACuO₂ and LnBa₂−xSrxCu₃O₇₋δ where Ln is a Lanthenide or Y and A={Mg,Ca,Sr,Ba}. We utilise a variety of techniques to explore different aspects of our paradox, for example; Raman spectroscopy to measure the antiferromagnetic superexchange energy and energy gaps, Density Functional Theory to calculate the density of states, Muon Spin Relaxation to measure the superfluid density as well as a variety of more conventional techniques to synthesize and characterise our samples. Our Raman studies show that an energy scale for spin fluctuations cannot resolve the different effect of the two pressures. Similarly the density of states close to the Fermi-energy, while an important property, does not clearly resolve the paradox. From our superfluid density measurements we have shown that the disorder resulting from isovalent-ion substitution is secondary in importance for the superconducting transition temperature. Instead, we find that the polarisability is a key property of the cuprates with regard to superconductivity. This understanding resolves the paradox! It implies that electron pairing in the cuprates results from either (i) a short-range interaction where the polarisability screens repulsive longer-range interactions and/or (ii) the relatively unexplored idea of the exchange of quantized, coherent polarisation waves in an analogous fashion to phonons in the conventional theory of superconductivity. More generally, we have also demonstrated the utility of studying ion-size effects to further our collective understanding of the cuprates.</p>
