Object Cloning for Ownership Systems
Authors:   , Li Paley Guangping 
Published: November 2021

<p>Modern object-oriented programming languages frequently need the ability to clone, duplicate, and copy objects. The usual approaches taken by languages are rudimentary, primarily because these approaches operate with little understanding of the object being cloned. Deep cloning naively copies every object that has a reachable reference path from the object being cloned, even if the objects being copied have no innate relationship with that object. For more sophisticated cloning operations, languages usually only provide the capacity for programmers to define their own cloning operations for specific objects, and with no help from the type system. Sheep cloning is an automated operation that clones objects by leveraging information about those objects’ structures, which the programmer imparts into their programs with ownership types. Ownership types are a language mechanism that defines an owner for every object in the program. Ownership types create a hierarchical structure for the heap. In this thesis, we construct an extensible formal model for an object-oriented language with ownership types (Core), and use it to explore different formalisms of sheep cloning. We formalise three distinct operational semantics of sheep cloning, and for each approach we include proofs or proof outlines where appropriate, and provide a comparative analysis of each model’s benefits. Our main contribution is the descripSC formal model of sheep cloning and its proof of type soundness. The second contribution of this thesis is the formalism of Mojo-jojo, a multiple ownership system that includes existential quantification over types and context parameters, along with a constraint system for context parameters. We prove type soundness for Mojo-jojo. Multiple ownership is a mechanism which allows objects to have more than one owner. Context parameters in Mojo-jojo can use binary operators such as: intersection, union, and disjointness.</p>
The Difficult Choices of a Post-Colonial State: Timor-Leste and International Educational Aid
Authors:   , Correia De Almeida Nene 
Published: November 2021

<p>Timor-Leste is still a newly independent country, obtaining full independence in 2002. The new Constitution gives all citizens a right to education, showing how important education is for Timor-Leste. Educational aid has accounted for around 10% of the aid budget (and has been as high as 28%) over the three years from 2011 to 2014. This thesis explores the emerging relationship between Timor-Leste and its two largest aid donors: Australia and Portugal, through the lens of educational aid. Although there are currently some studies on Timor-Leste’s education policy, there is no current study which explores the relationship between donor foreign policy and educational aid. The thesis builds on secondary literature and interviews with important figures in the Timorese government. It argues that donors’ political priorities have had an important impact on shaping education policy in Timor-Leste and that the provision of educational aid can help to highlight Timor-Leste’s position as a highly dependent nation in the world system. Portuguese aid has been strongly driven by Portugal’s attempts to maintain political relationships with its former colonies and promote Portuguese language worldwide. Portuguese funding for Portuguese language education has had an impact on language policy, cementing the position of Portuguese as an official language and promoting a Portuguese-influenced position in Timor-Leste’s foreign policy. Australian aid, meanwhile, has emphasised Tetum and English as appropriate languages and is connected with Australian attempts to minimise Timorese discontent over oil politics in the Timor Gap (or Timor Sea). Coordination between these two different donors with different interests has been weak. Timor-Leste finds itself in a difficult position of dependency whereby it needs foreign aid but cannot trust that aid is being given in a disinterested and functional way.</p>
Doing gender as an offender: A criminological analysis of offender narratives, and the interrelationship between masculinities and child sexual abuse
Authors:   , Ranger Laura 
Published: November 2021

<p>Masculinity is a powerful construct that transcends other aspects of male existence and dictates codes of conduct accordingly. Masculinity describes a plurality of roles, norms and expectations that regulate the behaviour of men. Within criminology, many theorists have established an association between threatened masculinity and sexual violence perpetrated against adults. Comparatively little attention has been paid to the relationship between masculinity and sexual violence perpetrated against children. What research there is, suggests that men who sexually abuse children may offend as a way of overcompensating for perceived masculine inadequacies that have arisen as a result of chronic experiences of powerlessness. This thesis is based on semi-structured, in-depth interviews with men who have sexually offended against children. Twenty men were recruited from community-based rehabilitation programmes around New Zealand. Transcripts of these interviews — as well as client records and results of a Q-sort task — were analysed to identify ways in which these men achieve, negotiate or defy normative gender expectations. A mixture of thematic and narrative analysis was used to interpret the data, revealing four prominent themes: powerlessness, entitlement, risk-taking and rigid thinking. Within each broad theme, several other factors were identified. For the theme of powerlessness these were: distorted perception, idealistic or nostalgic views of childhood, previous experience of trauma or abuse, an inability to seek help, experiences of humiliation or rejection, and perceived masculine failings. For the theme of entitlement these were: a propensity for resentment and blame, narratives of nice guys relegated to the friend zone, and valuing of hypermasculinity. For the theme of risk-taking these other factors were: narratives of boredom or addiction, as well as the existence of obsessive or compulsive tendencies. For the theme of rigid thinking these were: inconsistent or illogical cognitive patterns, poor or inappropriate boundary setting, and inflexible or unattainable religious ideals. Overall, the results lend support to current theories of powerlessness and show that men’s sexual offences against children can be interpreted as overcompensatory behaviour occurring within the spectrum of normative masculinities. These findings highlight the need for rehabilitation to consider offenders’ masculine identities as a point of treatment focus. It is argued that society must challenge the rigid and unattainable nature of hegemonic masculinity because of its potentially harmful consequences for men, women and children. It is hoped that the content of this thesis can contribute to academic knowledge about ‘doing gender as an offender’.</p>
Diversifying Density - Renovating Rural Living within Kapiti/Horowhenua Coast
Authors:   , Wheaton Nicholas 
Published: November 2021

<p>‘Diversifying Density’ explores current issues surrounding New Zealand’s struggling rural regions with particular focus on the test region of Kāpiti/Horowhenua Coast. These rural regions are subject to pressure from cities with regard to economic production and a cultural shift toward urban lifestyle. This has contributed to deconstructing much of what originally made these regions so attractive to live in. Through the process of revitalisation this research looks at the specific test site of Lake Horowhenua. While there is no shortage to these rural challenges, Lake Horowhenua has managed to retain particular significance within the overall region of Kāpiti/Horowhenua Coast. The focus area of this research is to explore a diverse hybrid settlement for a specific area based around a potential economy. On developing this, the design explores how this can provide new habitation while working towards a better environmental system and occupancy potential. This research looks to encouraging discussion about conservation by adding further economic opportunity, the displacement of some current practices with the benefit of economic, environmental, and spatial diversities. Pulling these elements together the thesis proposes that this generates further opportunity, to increase human occupancy, formulating a perception and involvement within this rural landscape. Reconfiguring rural economies, lifestyles, recreation and conservation encourages authenticity of rural landscapes, creating new experiences and opportunities building the notion of abundance. The research being tested in detail is the harakeke (flax) economy. It is structured around the processing stages involving the extraction of the harakeke fibre. Developing this concept through one economy generates new opportunities for habitation, while facilitating alternative growth specific to the site and economy. This informs design moves that are directed specifically toward the economic and environmental diversity drivers connected to the site for growth encouragement. Then begins the exploration of concepts of authenticity; new rural living patterns; interdependencies of economies; environment and spatial patterns; and developing a synergy between work and living to construct community.</p>
Twisted magnetization phases in orbital-dominant rare-earth nitrides
Authors:   , McNulty James 
Published: November 2021

<p>In this thesis we investigate the magnetic properties of NdN and SmN, members of the rare-earth nitrides, a series of intrinsic ferromagnetic semiconductors. In rare-earth systems, the strong spin-orbit coupling of the partially filled 4ƒ shell ensures that there is a substantial orbital contribution to the ferromagnetic moment, in contrast to many transition metal systems where the orbital moment is usually quenched. In SmN and NdN the orbital moment actually exceeds the spin moment, and the resulting orbital dominant magnetization allows for the fabrication of a magnetic heterostructures showing novel behavior. We report a new theoretical study of the magnetic properties on both SmN and NdN by considering the atomic-like 4ƒ electrons. These calculations incorporate spin-orbit coupling, the exchange interaction in a self-consistent mean-field approach, and crystal field interactions in an arbitrary-multiplet point-charge model. Our findings show excellent agreement with the experimentally measured ferromagnetic moments of SmN and NdN, representing an advance from previous theoretical studies. We also report an experimental study on SmN/GdN heterostructures using the element-resolved method of x-ray magnetic circular dichroism (XMCD) to probe the magnetism. The competition between the orbital-dominant Zeeman coupling in SmN and the ferromagnetic spin-based interface exchange with GdN, which has purely a spin moment, results in a twisted magnetization profile. The depth profile of the magnetization derived from XMCD measurements showed good agreement with an analytical model developed to describe the competing interactions. In a second study, a superlattice of NdN/GdN was investigated via XMCD and standard magnetometry techniques. A twisted magnetization was shown to be present due to the same mechanism as in the SmN/GdN system. By varying the maximum applied field and temperature, twisted phases were shown to develop in both GdN and NdN layers. These twisted phases in orbital-dominant ferromagnetic semiconductors represent a departure from previously explored spin-dominant metallic systems displaying similar twisted phases.</p>
Does Seston Quality Limit the Presence of Mussels on Wellington’s South Coast? FlowCAM investigation of seston particle type
Authors:   , Rodgers Rata Pryor 
Published: November 2021

<p>Temperate rocky shores around the world are characterised by so-called ‘universal’ zonation. An interesting exception to this rule can be seen along the shores of Wellington’s South Coast where there is a virtual absence of mussels and poorly developed rocky shore intertidal community. Yet just kilometres away in Wellington Harbour there is a fully developed intertidal community, including extensive multi-species mussel beds. This thesis aims to determine if the quality of seston is limiting the presence of mussels on Wellington’s South Coast. We now have the technology to see what types of particles the mussels are selecting in low and high quality seston conditions using a FlowCAM that allows identification of particle types and their physical properties. This study compared environmental data for Wellington Harbour (seston-rich) and the South Coast (seston-poor). These data included chlorophyll a, turbidity and suspended sediment concentrations and were collected by CTD and satellite remote sensing. Mussel feeding experiments took place under a high and low quality diet during summer, autumn and winter using Perna canaliculus and Mytilus galloprovincialis. The physiological responses recorded were clearance rate, absorption efficiency and net energy balance for individual mussels. Environmental variables recorded were total particulate matter, particulate organic matter and percent organic matter. Water samples were collected during the feeding experiments and processed using the FlowCAM. By comparing the control chambers to chambers that had mussels feeding in them it was possible to see what particles the mussels were selecting. The environmental variables revealed that Wellington Harbour had a much higher quality seston whereas in Cook Strait the seston quality was too low for mussels to be able to inhabit, as the chlorophyll a concentrations did not reach the required levels for mussel growth. Perna canaliculus and Mytilus galloprovincialis both showed physiological responses that would allow them to grow in Cook Strait waters, both species had positive absorption efficiencies and net energy balances. These responses were greater in the high quality diet in the enriched pond water in Nelson during summer and winter. The FlowCAM analysis revealed an inter-specific difference in preferential particle selection, which varied as a function of site and season. With more particles being preferentially selected in the high quality diet compared to when the mussels were feeding on Cook Strait seawater. This new information of particle selection helps to determine why mussels are absent from Wellington’s South Coast and contributes to the extensive information on mussel feeding.</p>
Electronic portfolios in early childhood education: Parent-teacher communication
Authors:   , Higgins Amanda 
Published: November 2021

<p>Electronic portfolios (ePortfolios) are a new phenomenon in early childhood education (ECE) and there is minimal existing research available on their use and effectiveness as a learning and communication tool in ECE. This thesis presents an exploratory case study of an ECE centre, positioned within a constructive-interpretivist paradigm, which investigated communication between teachers and families via ePortfolios. Data used in the study were drawn from online surveys, document analysis of ePortfolios, individual interviews, and focus group interviews with parents and teachers. Thematic analysis identified three main themes; the benefits and drawbacks of communicating via the ePortfolio, the online tools that supported or constrained communication, and the types of communication that were evident. Several implications for teachers’ practice arise from this study. First, the ePortfolio enabled communication to easily flow between settings, and provided another avenue for teachers and parents to communicate. Second, the different levels of communication parents and teachers engaged in via the ePortfolio had potential to influence their on-going communication, relationships, and children’s learning. To extend on-going learning and positive learning outcomes for children, online communication could be scaffolded so that a focus on relationships moves toward to a greater focus on children’s learning. Finally, levels of trust between teachers and parents were apparent, though more complex elements of trust such as competence and openness were less evident. Teachers could consider ways to develop these with parents to further enhance trust and communication.</p>
"Towards a Positive Treaty Partnership in the Post-Settlement Era”: Treaty of Waitangi Settlements and Decolonisation in Aotearoa New Zealand
Authors:   , Summerfield Scott 
Published: November 2021

<p>Settlements of historical Treaty of Waitangi claims present a unique opportunity to provide redress to Māori for the past and ongoing grievances committed by the Crown, and through that redress and the accompanying focus on improved relations, to decolonise the relationship between the two. Despite this opportunity, there is a wide body of literature that suggests the outcomes of these settlements instead will perpetuate colonisation and uphold the political structures which allow for the on-going dispossession of Māori. This thesis argues that existing Treaty settlement policy can be viewed as a continuation of the legacy of colonisation by stealth, entrenching the power of the colonial state while simultaneously offering redress and apologies for past grievances of the colonisation process which do not adequately challenge the underlying structures which give rise to those grievances. It is further argued, through the example of political rhetoric from the 2014 general election, that current political discourses support the implementation of colonising settlement policies and that those discourses reinforce notions of Western settler superiority. This thesis explores a number of perspectives on settlements and decolonisation which support the claim that historical Treaty settlements perpetuate rather than challenge colonisation. I argue that the pressing concern emerging from the thesis is that the Crown can be to seen to be directing the Treaty relationship to a post-settlement world where the negotiated outcomes of Treaty settlements and the parties to them are the end point of colonisation and represent the future dynamic of the Crown-Māori relationship.</p>
Modelling Surtseyan Ejecta
Authors:   , Greenbank Emma 
Published: November 2021

<p>Surtseyan ejecta are formed in shallow sub-aqueous volcanic eruptions. They occur when water, containing a slurry of previously erupted material, is washed into the volcanic vent. This slurry is incorporated into the magma and ejected from the volcano inside a ball of magma. These magma bombs containing entrained material are called, Surtseyan ejecta or Surtseyan bombs. At the time of entrainment there is a large temperature difference between the magma (at approximately 1000°C) and the slurry (at approximately 20°C). As the inclusion temperature increases, the water contained in the slurry evaporates, causing an increase in the pressure at the boundary of the entrainment. This pressure increase is offset by the vapour diffusing through the pores of the magma. If the pressure exceeds the tensile strength of the surrounding magma the Surtseyan ejecta will rupture. The volcanological question of interest is whether the magma ruptures. There is evidence of intact ejecta so it can be concluded that rupture does not always occur. We have developed a set of equations that transiently model the changes in temperature and pressure in Surtseyan ejecta. Numerical solutions show that the pressure rapidly increases to a stable value. Because the pressure reaches equilibrium a steady-state solution can be used to determine the maximum pressure and a criterion for rupture.</p>
Using Paleoecological Proxies to Determine Holocene Environmental Change: A Case Study at Onaero Beach, North Taranaki
Authors:   , Skudder Rachel 
Published: November 2021

<p>A multi-proxy paleoecological and sedimentological record for the last ~8.3kyr is extracted from a 2.1m coastal seacliff at Onaero Beach, North Taranaki. This record is used to infer both local environmental changes including shoreline, coastal conditions, as well as regional changes in atmospheric circulation and climate wetness. Analysis of diatom and pollen populations, particle size, and loss on ignition provide the raw data from which inferences regarding salinity and vegetation are made. Changes are tied to a chronology determined through radiocarbon ages and tephrochronology. Key objectives of this study are: (1) To characterize changes in salinity and relative shoreline position at Onaero Beach (2) To characterise changes in vegetation and relate these changes to overall state of the climate through the Holocene (3) Compare the results of this study with others from New Zealand and the wider south pacific to investigate how the Onaero Beach section fits in both a regional and global context. Diatom analysis of the Onaero section revealed the dominance of brackish to marine species which suddenly at 7.3ka after which time diatom assemblages were dominated by fresh and salt intolerant species. The marine to freshwater transition represents a transition from a brackish to freshwater coastal lagoon. Pollen analysis of the Onaero Beach section indicates the region was dominated by podocarp forest. The increasing dominance of Dacrydium and decline in other podocarps suggests an increase in overall climate wetness. The disappearance of pollen in conjunction with the deposition of tephra at ~4.15ka is not conclusive proof of, but certainly fits with, the idea of a significant climatic event occurring at ~4.2ka resulting in a reversal of the current prevailing wind direction and supports the case for a formal Middle/Late Holocene boundary at this time.</p>
New Zealand's 'overstaying Islander' : a construct of the ideology of 'race' and immigration
Authors:   , Ross Tamara Brigid 
Published: November 2021

<p>This thesis examines the development of a 'race'/immigration ideology within New Zealand and attempts to explore the processes through which this ideology has expressed and reproduced itself in New Zealand's past. In order to determine this process, this thesis analyses, as a case study, the causes, patterns and consequences of the politicisation of Pacific Island immigrants in New Zealand during the 1970s. Pacific Island immigrants were negatively categorised according to traditional New Zealand beliefs about 'race' and the immigration of 'alien' peoples, and the stereotypes that arose out of this process justified racist immigration campaigns in the 1970s. The targeting of Pacific Island migrants through these immigration campaigns, and the deliberate scapegoating of Pacific Islanders in the 1975 general election, compounded and entrenched existing negative stereotypes thereby justifying the further politicisation of Islanders in the 1980s. It is argued that this historical process needs to be understood as the outcome, among other things, of the 'race'/immigration ideology. Furthermore, it is demonstrated that the politicisation of Pacific Islanders during this period was but part of a cycle in a larger process of the generation and reproduction of racism. While the 'race'/immigration ideology is analysed here with Pacific Islanders The historical campaigns against Pacific Islanders are examined in detail so as to illuminate the broader process of racialisation in New Zealand's past, and to explore the possible form that the 'race'/immigration ideology may assume both in the present and in the future.</p>
