High Temperature Superconductors Through the Van Hove Singularity
Authors:   , Williams Keryn Anne
Published: November 2021

The antibonding VHS of the high temperature superconductor Bi-2212 appears in the extreme overdoped regime, a part of the cuprate phase diagram little studied to date. Observation of this VHS motivated taking a fresh look at the cuprates using fundamentals of electronics as the foundation for understanding the physics involved in the superconductivity of these materials. In the study of the high temperature superconductors it appears important questions have been overlooked, notably the possible contribution of the gapped state and whether these materials are better considered as doped semiconductors rather than as 'poor' metals. We also find the question of the contribution of oxygen, a substance with a strong magnetic signature, to data of the oxygen-doped cuprates has been neglected. Comparison with non-oxygen doping is supportive of the view the oxygen dopant contributes noticeably to magnetic data. Through magnetic susceptibility measurements the antibonding VHS location, predicted by use of Fermi liquid theory, is well confirmed in polycrystals of the lead-doped cuprate Bi-2212. It was found that the peak in the DOS at the VHS produces no corresponding local peak in the critical temperature versus doping. Instead, the VHS appears associated with the disappearance of the superconductivity, rather than with the maximum critical temperature. We find the metal-insulator transition plays an important role. There are two of these in the cuprates, a horizontal doping dependent one and a vertical temperature dependent one. They affect each other. Noting the consequences of doping an insulator until a metallic state is reached enables a connection to be made between doping and pressure. Three requirements are identified for superconductivity to occur: 1. screening 2. pairing 3. charge mobility Each requirement may be separately satisfied in a manner whereby each can vary differently as a function of the same variable. The superconductivity of the cuprates is found to arise out of an underlying non-metallic state. As such, BCS theory, being formulated to explain superconductivity arising from metallic conduction, cannot be directly applicable. However, although HTS materials are a rich repository of both novel and familiar solid state physics, evidence does not appear to support the notion that superconductivity in the cuprates is caused by "exotic" physics. We also find cause for optimism regarding the development of new or improved superconducting materials.
Utilising Practice Development and the PARIHS Framework to Implement the Liverpool Care Pathway
Authors:   , MacKenzie Theresa Mary
Published: November 2021

The LCP is an evidence-based integrated care pathway that provides guidance to generic health care professionals to deliver best practice end-of-life care. My role as the LCP Project Coordinator in a District Health Board in New Zealand is central to the exploration of this process of implementing practice change. Working with clinicians to advance effective care and management of patients during the process of dying in an acute hospital setting requires not only knowledge and understanding of the clinical pathway and evidence supporting best practice, but also careful working with cultural and contextual change. This paper descriptively addresses the bases of both components, and provides a case example of the development. Working with health care professionals to bring about practice change is complex and challenging. Successful implementation of evidence in practice is dependant not only on the strength and nature of the evidence, but also the context and models of facilitation. Practice development (PD) methodology informs the realities and complexities of practice change and of achieving sustainable development. The 'Promoting Action in Research Implementation in Health Services' (PARIHS) framework identifies the interplay and interdependence of factors that resonate with the reality of the complexity of practice change in relation to the evidence and best practice for particular clinical contexts. Highlighting PD processes and the relevance of the PARIHS framework alongside real-time practice change will continue to stimulate recognition of change and development complexities and bring consideration of these as robust methods for working between the theory and implementation of evidence in practice.
Artefactualism as an Ontology of Art
Authors:   , Hamel Alistair
Published: November 2021

This thesis argues for artefactualism about works of art, which is the claim that works of art are artefacts. It does this by considering the cases of works of music, and works of fiction, and arguing that each of these are artefacts, or existent, created, individual entities. To do this, it argues against anti-realist, eternalist, and type theories in these domains. The thesis draws on arguments made by philosophers such as Amie Thomasson regarding fictional characters and Guy Rohrbaugh regarding repeatable works of art.
Taming the Wild West: a Framework for Regulating and Applying Broadcasting Standards to Internet Content in New Zealand
Authors:   , Dearing Matthew Charles
Published: November 2021

The role of the Broadcasting Standards Authority (BSA) is to determine the areas where, and the extent to which, television and radio broadcasters' right to freedom of expression should give way to other interests that are highly valued in society. The BSA does this by applying the Codes of Broadcasting Practice, which contain standards relating to things such as good taste and decency, balance and accuracy in news and factual programmes, privacy and children's interests. Due to a combination of media convergence onto the Internet and outdated legislation, the BSA is finding itself caught in a techno-legal time gap, where it has no ability to deal with programming content provided by broadcasters via the Internet. In the not-too-distant future, the Internet will become the dominant platform of choice, both for broadcasters to provide programming content and for consumers to receive it. This dissertation examines the impact that the Internet has had on the modern media environment and the problems raised by the BSA's lack of jurisdiction to deal with programming content located on the websites of New Zealand-based broadcasters. To ensure that the BSA and the broadcasting standards regime in general does not become obsolete, this paper advocates for the BSA to be given express statutory jurisdiction to deal with complaints concerning programming content on New Zealand-based websites operated by Internet broadcasters.
Female Scarcity and Natal Dispersal Differences Between Sexes Among Bellbirds (Anthornis melanura)
Authors:   , Cresko Hilary Misha
Published: November 2021

Sex ratio imbalances in wild bird populations have been a challenge for wildlife managers for decades. Differences between sexes during natal dispersal has long been thought to promote sex ratio imbalances. Natal dispersal distances may differ between sexes because of competition for food and space, or intrasexual competition and aggression. I investigated natal dispersal and intrasexual competition as mechanisms for a sex ratio imbalance in a small, translocated population of a New Zealand honeyeater, the bellbird (Anthornis melanura) in the Karori Wildlife Sanctuary- Zealandia, Wellington, New Zealand. I analysed long term records of population size and structure to document annual variation in sex ratios since the reintroduction of bellbirds to Zealandia. Radio telemetry was used to track the 2008/2009 cohort of bellbirds for five months after fledging to observe movements and distances travelled from their hatching location. Observations at a supplemental food source that was used by both adults and fledglings, were used to study intrasexual competition and aggression. Dispersal distances did not differ between the sexes for any of the measurement types used. Males did however significantly dominate the use of a supplemental food source and were significantly more aggressive around this food source, which is most likely responsible for the lower feeding rate among females. Therefore, I conclude that the sex ratio imbalance in the bellbird population in Zealandia may not result from a difference in natal dispersal, but from males dominating a supplemental food source, raising their population and fitness over that of females.
Patent as a Generator Rather than Inhibitor of Drug Accessibility in Developing Countries: a Critical Examination of India's Patent Model
Authors:   , Pitkovsky Gilat Ezra
Published: November 2021

Patent's reputation as a constructive mechanism in the developing world was not a common notion. The prospect of utilising pharmaceutical patents to generate drug accessibility in developing countries did not seem possible. However, little credit was given to patents. Through motivating innovation, foreign investment, trade relations and industrialisation, patents can form a prowess pharmaceutical industry in the developing world. This thesis explores the possibility to increasing the availability of low cost drugs in emerging economies through patent enforcement. The analysis focuses on India as a case study. India has long been at the forefront of the developing world fight for low cost drugs markets. This stand once meant the exclusion of patent protection of pharmaceutical innovation and the formation of low cost copied generic drugs industry. However given developing countries' recent submissions to the international pressure to enforce patent protection on pharmaceutical innovations, it is time to re-examine the role patents play in developing countries, this time in the avenue of reducing drugs' pricing. India's current economy and the evolution of its pharmaceutical industry evolvement, make it as an exemplary case study to utilise patent to fulfil this end. Accordingly, the issue of widening the scope of patent protection in India to include pharmaceutical incremental innovation is examined. Notwithstanding the responsibility of India to endorse wider patent scope, legally and practically, the thesis does not ignore the moral obligation the developed world has towards India's poorer population to offer low cost drugs during the stages of its pharmaceutical industry emergence. The preliminary justification to conduct this observation is to show that patent is not only to answer the healthcare needs of the developed world population, but also the developing world. As such the thesis argues that India ought to stand at the forefront again, this time, demonstrating the potential within patent to establish low cost patented pharmaceuticals marketplace in developing countries.
Feeling Their Way: Four Men Talk About Fatherhood in Valparaiso, Chile
Authors:   , Evans Monica
Published: November 2021

In this study, I explore the experiences and understandings of fatherhood of four men in Valparaiso, Chile, who became fathers between the ages of 16 and 19 and lived geographically, but not emotionally, distant from their children at the time this fieldwork took place. I seek thus to interrogate stereotypes in social discourse, Gender and Development research and many institutions about Latin American fathers in similar situations (Viveros 2001). Given the emotionally-intense nature of this project, I also examine the impacts of emotions and empathy on the relationships that were developed within it, and on researcher and participant subjectivities inside and outside the research process - a topic seldom addressed in social science literature (Bondi 2005). In framing this research, I draw on feminist, poststructural, structurationist and Participatory Action Research epistemologies, as well as ways-of-knowing that are indigenous to the area in which fieldwork took place. Methodologically, I carried out a series of unstructured and semi-structured interviews with each participant, and spent considerable time 'hanging out' with them as well (Kearns 2000). I also interviewed Chilean academics and practitioners working on issues of masculinity and fatherhood, both individually and in a group discussion. Presenting the work, I use stand-alone 'story sections' as well as interpretive chapters. These story sections provide more space than a 'straight' chaptered structure might allow for each man's personal tale to be told. I postulate that all four participants were emotionally compelled to 'father' and found spaces in which to do so, despite "larger stories" (Aitken 2009, 15) about youth, fatherhood and family that constricted their participation in their children's lives (Aguayo & Sadler 2006). Yet, they all remained unsatisfied with the "fathering spaces" (Aitken 2009, 171) that they were able to negotiate, and all felt pain as a result of this. Being recognised and emotionally understood 'as fathers' through empathetic engagement with me within this research process was thus a largely positive and sometimes transformative experience for participants. Such engagement also helped me to navigate concerns about positionality and representation, and reflecting on it later on enabled me to 'process' this emotionally-intense process, and to shift and deepen my analysis. In sum, the study offers an intimate, nuanced perspective on four men's fatherhoods and my experience of working with them, which I hope will contribute to more careful characterisations of men in similar situations in Gender and Development literature, and to scholarship on emotions and empathy in research relationships more generally.
The Role of Emotional Content in the Control of Eye Movements
Authors:   , Phillips Joseph
Published: November 2021

The anti-saccade paradigm has been a favourite among researchers of attention and the control of eye movements. Most pro/anti-saccade studies have utilized meaningless stimuli, though stimulus meaning is known to have an impact on looking behaviour in free viewing conditions. Here, we explore the role of content in the control of pro/antisaccades by contrasting two alternative views on the impact of emotional stimuli. One view supports an "informativeness" hypothesis, where visual processing is directed towards threatening stimuli, suggesting that RT should be particularly large for negative, high arousal pictures in an antisaccade task. An alternative view emphasizes approach and withdrawal behaviours. Here negative images are thought to encourage avoidance behaviours, causing faster RTs for antisaccades; whereas positive pictures encourage approach behaviours, causing faster RTs for prosaccades. Participants performed an antisaccade task in which they were presented with an image to the left or right visual field and instructed to look at or away from the image. The experimental design included five groups of images, with a factorial combination of valence (positive or negative) and arousal (high or low), and a neutral condition. In Experiments one and two the instruction was given 200 ms before the picture was presented and did not produce any effects of emotional content. Thus, if participants are given advanced notice of the upcoming saccade, the initiation of that saccade is not influenced by the emotional content of the target image. In experiments three and four, the cue was presented 200 ms after the onset of the target image. This change of SOA provided an effect of emotional content was observed in experiments three and four which was illustrated by slowed RTs for both pro- and anti-saccades. However erotic images appeared to slow down latencies across both saccades which were accompanied by high error rates.
Guidelines to Make Victoria University School of Architecture and Design Carbon Neutral Through Minimising its Reliance on Carbon Offsets
Authors:   , Ryu Soo Jung
Published: November 2021

Universities have always had an important leadership role in society in demonstrating the types of changes that need to occur with respect to the prime issues of the time. All around the world, universities are lining up to declare themselves the next carbon neutral school as part of the global trend of becoming "sustainable." But what does it really mean to be carbon neutral? In 2007 Victoria University's School of Architecture and Design (SoAD) declared themselves the first carbon neutral campus in the world through the use of sponsored and purchased carbon credits. However 100% reliance on offset schemes is not the answer as it does not guarantee the capture of carbon forever. Also, the continuing purchase of carbon offsets could be costly and maintaining businessas- usual without any significant changes will result in continuing environmental degradation as a result of the SoAD's unsustainable activities. This research explores various solutions for reducing the three biggest factors that contribute towards the emissions, which are energy, transport and waste. It looks at the difference between behavioural changes (low cost) and technological investment (high cost) in order for SoAD to reduce its carbon footprint to meet three possible reduction targets, established by this research as 25%, 50% and 90%. The findings are that 25% could be saved through simple behavioural changes which cost very little, as they are mainly related to avoiding wastage, 50% could be saved through a combination of low and high cost measures, and 90% comes from considerable investment in new technologies or drastic reduction in use. A further aim of the research is to translate all possible savings into other means, such as knowing how much carbon or land is saved, using a measure such as the ecological footprint, and more importantly what these savings mean to the third world where resources are scarce and expensive. If SoAD's wasteful activities from neglect can be translated into saving people's lives in other nations, it might lead to more responsible energy use. What this research indicates is that for SoAD to be carbon neutral various factors need to be considered and user behaviour is paramount.
Reflections on Perceived Online Service Quality: Structure, Antecedents, Ontology, Theory and Measurement
Authors:   , Tate Mary
Published: November 2021

Online services are becoming increasingly ubiquitous, and this growth has been accompanied by increased business interest in measuring and managing online service quality. This interest is also reflected in a large number of academic studies. Despite this, there is very little consensus about the dimensions and antecedents of perceived online service quality (POLSQ). We consider two possible reasons for this: first that the phenomenon of online service quality is changing as new technology affordances arise, so instability in the dimensionality would be a result of changes in the underlying phenomenon. Second, the theoretical approach and assumptions that studies of online service quality are usually founded on is flawed. My research questions are: 1) what is the structure of perceived online service quality? 2) What are the antecedents of perceived online service quality? 3) What is the ontology of perceived online service quality? 4) What are the most appropriate modelling and measurement methods for measuring online service quality quantitatively, and what insights can be gained from psychometrics?5) What insights does this offer IS researchers for the measurement of user attitudes and perceptions towards technologies? We find that leading models and instruments tend to be based on exploratory factor analysis and have not been informed by advances in measurement theory, particularly co-variance-based structural equation models, and a sub-set of those models known as multi-indicator structural models. We apply recent advances in measurement theory to a dataset. We apply and compare four different modelling methods, exploratory factor analysis, confirmatory factor analysis, formative models, and multi-indicator structural models, and discuss the theoretical foundations of each method. We conclude that POLSQ may not have a separate ontology as a multi-dimensional construct, but overall affect towards the service quality of a website is likely to be the result of the perceived usefulness, perceived ease of use, and perceived trust towards the service. This finding supports the explanatory power of information systems theories over marketing and consumer behaviour theories when studying this phenomenon. We find that user's perceptions of detailed affordances of the service, such as the relevance and timeliness of the information are antecedent to overall affect towards the service, rather than being additional dimensions of POLSQ. We find that widely used techniques such as exploratory factor analysis have serious drawbacks. We find that multi-indicator structural models provide an accurate and nuanced method for modelling the formation of attitudes and perceptions towards technology, which is also well-grounded in theory from social psychology. Finally, we suggest that the approach we take to measuring POLSQ is has potential value for other research which aims to measure customer attitudes and perceptions towards technologies.
Representations of Female Adolescence in the Teen Makeover Film
Authors:   , Marston Kendra
Published: November 2021

This thesis proposes to analyse the representation of female adolescence in the contemporary teen makeover film. The study will situate this body of films within the context of the current postfeminist age, which I will argue has bred specific fears both of and for the female adolescent. This thesis will examine the construction of the initial wayward makeover protagonist, paying attention to why she needs to be trained in an idealised gender performance that has as its urgent goal the assurance of heteronormativity and 'healthy' sex role power relations. I will also analyse the representation of deviant adolescent female characters in terms of how their particular brand of postfeminist female masquerade masks a power and status-oriented agenda. The behaviour of these characters is shown to impact negatively on the peer group within the film, and is particularly dangerous as it threatens to negate the need for romance.
The Impact of Performance Audit: the New Zealand Experience
Authors:   , Abd Manaf Nurul Athirah
Published: November 2021

Performance audit, compared to the traditional financial and compliance audits, is a relatively new innovation that emerged amidst accountability concerns in the public sector. Economic crises, ministerial scandal and inefficiencies were among the impetus that led the public to demand better performance and greater accountability in the public sector, and performance audit was among the many responses to such demand. In New Zealand, performance audit is carried out by the Controller and Auditor General (the AG) under the mandate granted by the Public Audit Act 2001. Adapting the methodology from grounded theory, this study looks at the impact of performance audit on seven entities audited in 2006 by the AG. This study found that the entities were impacted through the manifestation of implemented audit recommendations and the attainment of performance audit goals. In particular, there is a high acceptance and implementation rate to the audit recommendations made in the seven audits. The implementation of accepted recommendations consequently led to the changes within the entities in terms of managerial practices, as well as internal systems and processes. In some entities, these changes were translated into performance improvement, where the entities experienced changes in the way that they carried out their operations. However, based on interviewees' accounts being the auditees of the audits, most interviewees viewed performance audit as having a greater role for performance accountability compared to performance improvement. Whilst the auditees found the audit recommendations useful, the impact on performance in their view has not been significant. Rather, the auditees viewed performance audit as having a more important role as an assurance tool in terms of their accountability to the public.
Administrative Professionals in New Zealand: Their Professional Development Opportunities and Career Pathways
Authors:   , Lloyd Ethelwyn Eva
Published: November 2021

This descriptive study to investigate the perceptions of administrative professionals of their professional development opportunities and career pathways was conducted mid-2009. The study used an on-line survey and focus groups. One hundred and ninety-three responded to the survey from throughout New Zealand. Fifteen of those respondents participated in the focus groups, held in both the North and South Islands. The majority of participants were from larger organisations who perceived that training and professional development was available for them and supported. However, the professional development available was often ad hoc, with no specific goal. Many participants perceive themselves as undervalued within the business world and noted that even where support for professional development was available there were significant barriers. These barriers, impacting on the availability and the uptake of professional development opportunities and career pathways, were both internal (value of self) and external. A conceptual framework is presented of the relationship between the key elements from the research, value of self and value of the role, and the impacts of those on professional development opportunities and career pathways.
Crown Liability in Tort in New Zealand
Authors:   , Neazor Daniel Paul
Published: November 2021

Direct review by the Courts (e. g . by prerogative writs) of Executive acts and decisions generally provides the individual citizen with a means of overcoming for the future the adverse effects of such decisions and actions, but it does not provide any means of compensating him for detriments to his interests already caused . Such detriments will generally be those which have accrued in full by the time the decision is reviewed but may in some cases be of a continuing nature, e. g . where, because of refusal of a licence, a business opportunity is lost. Tort actions against the State on the other hand, will allow the Courts not only to examine the actions of State servants, and determine whether they conform with the Courts' view of the proper behaviour of officials but also, and principally, to compensate the individual citizen whose interests have been affected by State action. Such actions may thus furnish an indirect means of control of the Executive as well as a means of compensation for injury.
Forests for Participatory Democracy: Emergent Patterns in the Interaction of Actors and Space in a Community-Based Sustainable Forestry Project in San Francisco Libre, Nicaragua
Authors:   , Sinreich Lauren
Published: November 2021

The host of literature on community-based sustainable forestry initiatives cites a profound schism between theory and the actual devolution of power and conservation of natural environments. This thesis set out to analyze the workings of power in a decentralized sustainable forestry project in San Francisco Libre, Nicaragua, and to account for how the myriad relevant actors influence, and are influenced, by the interactions and opportunities that arose. Taking a co-constructivist, relational approach, the case study undertaken found sustainable forestry and participatory democracy to be co-constitutive. However, where modernity has been touted for freeing society from the constraints of the natural world through science and technology, the very democracy and sustainability these initiatives are striving for are constrained by the modern framework upon which many of our institutions are built. By abandoning such nature vs. society dichotomous frameworks, socio- political initiatives can better account for the place-based, relational agency human and non-human actors share, and therefore create more effective, participative democratic institutions.
Population Viability and Resource Competition on North Brother Island: Conservation Implications for Tuatara (Sphenodon Punctatus) and Duvaucel's Gecko (Hoplodactylus Duvaucelii)
Authors:   , Wilson Joanna
Published: November 2021

Population viability for small, isolated populations is determined by many factors, particularly demographic stochasticity. Coexistence of communities is promoted through resource partitioning, particularly if species share similar niche requirements. Demographic characteristics, long-term trends and patterns of partitioning were investigated for two reptile species: tuatara (Sphenodon punctatus) and Duvaucel's gecko (Hoplodactylus duvaucelii), using mark recapture techniques on North Brother Island, New Zealand. Capture time and location were recorded as well as snout-vent length, mass and sex of individuals. Adult population size, sex ratio, survival and recapture probability for both species were estimated. Intervention will be needed to prevent population collapse for tuatara, as the population is male-biased (3.24 males: 1 female), with sub-adults exhibiting a stronger bias (4.1 males: 1 female). The total population size is estimated at 390-437 adults, with high adult survival (95%). The Duvaucel's gecko population is stable enough to be harvested for translocation, as the population was estimated at 583-677 adults, with an even sex ratio. Adult survival was high (92%) and longevity is at least 43-50 years. Patterns in partitioning suggest tuatara are excluding Duvaucel's gecko as tuatara occupy vegetated areas and few animals were caught at the same time in the same place as a member of the other species (~10%). Long-term site fidelity appears to occur in both species as the majority of animals were captured previously within 10m (tuatara) or 15m (Duvaucel's gecko) of their 2008 location, and travelled less than 2m per year on average. Tuatara show an overall decline in body condition since 1957, which is more rapid in females, and may be related to intraspecific interactions and density-dependent effects. Gecko body condition is not declining, suggesting no negative effects at the population level are occurring as a result of competitive exclusion. This study indicates that characteristics that have implications for population viability have the capacity to differ, even for species with similar niche requirements occupying the same habitat, and supports the considerable value of long-term monitoring.
Evolving Role of the Courts: Constitutional Review of Legislation under the New Zealand Bill of Rights Act 1990
Authors:   , Connell Charlotte
Published: November 2021

The constitutional landscape in New Zealand has undergone significant change over the last 20-35 years to improve the transparency and accountability of decision-making in the three branches of government. While most of these changes are a direct result of legislation, the constitutional role of the court has also been evolving and has seen the development of judicial review of the substance of the law for consistency with the New Zealand constitution. The orthodox view of the constitution is heavily critical of judicial, or constitutional, review of legislation by the courts and considers it to be an illegitimate encroachment on the domain of Parliament. This paper explores the legitimacy of constitutional review of legislation by the courts, specifically constitutional review of legislation under the New Zealand Bill of Rights Act 1990 (the Bill of Rights Act). To be legitimate, constitutional review by the courts must have both legal authority and be performed consistently with the constitution. This paper observes that s 5 of the Bill of Rights Act has been employed by the courts, without interference from Parliament, to review legislation for consistency with that Act and that the courts use the purposive approach to interpretation and the proportionality analysis to perform such review consistently with the constitution. Finally, the paper explores whether the developing jurisdiction of constitutional review necessitates a new paradigm to define the constitutional relationship between the courts and Parliament because the orthodox view of New Zealand's constitution is no longer supportable as the definitive position
Contesting Collective Representations of the Past: The Politics of Memory in South Korea
Authors:   , Vink Thomas
Published: November 2021

Because monuments, memorials and other 'sites of memory' privilege particular collective interpretations of the past over others, they represent inherently contentious and political spaces. Contention over representing the past is particularly resonant in Korea, where sites of memory are imbued with strong, often polarised meanings. By focusing on two such sites in Korea, this thesis seeks to discuss the wider implications of the ongoing conflict over what representations of the past should be privileged. In Gwangju, the area surrounding the former provincial hall (docheong) is being redeveloped, part of the city's attempts to become 'reborn' as a capital city of human rights and democracy in Asia. However, to many citizens in Gwangju, this new image ignores the meaning that the city's dissident past holds for local communal understandings of identity. Conflict arose as citizens protested to keep the symbolism of the docheong intact, thus, helping to maintain local narratives of the past. In Seoul, Myeongdong Cathedral, a key symbol of protest and democracy in the 1970s and 1980s, is now having its meaning re-interpreted, as the Catholic Church de-couples religion from socio-political concerns. The conflicting meanings of Myeongdong Cathedral are representative of a wider divergence in Korean society, as apathy towards Korea's past grows among society at large while other segments appropriate the past to protest contemporary socio-political concerns. Ultimately, these Korean case studies emphasise that the meanings sites of memory convey are not fixed, and that groups are often able to appropriate sites to affirm their own narratives of the past and to emphasise their own collective voice. Therefore, sites that represent particular understandings of the past, while contentious, also provide a space for debate and, thus, help to understand ongoing concerns within wider society.
Missing Links
Authors:   , Dormer Rodney
Published: November 2021

In the context of the worst economic shock that the world has experienced for eighty years, the New Zealand Government has announced a campaign to establish "a more focused, efficient and productive public service" (Whitehead, 2009). As the emphasis of managing the performance of the public service swings away from effectiveness and outcomes back towards efficiency and outputs, the practical and underlying tensions of managing within individual agencies remain. This research explored these tensions in relation to the performance measurement and management practices in three of New Zealand's public service agencies, namely Work and Income, Public Prisons and the Community Probation Service. For each of these agencies, the official performance management models as defined in relevant legislation and the agencies' external accountability documents (primarily their statements of intent and annual reports) are described. Note is also made of the 'formal' frameworks encoded within each agency's computer applications. These frameworks are then compared to an analysis of interviewees' descriptions of the performance measurement and management practices in use within those agencies. A framework by which the official, formal and in use performance management models within public service agencies may be better understood and aligned is then explained. This model utilises a competing values framework composed of two axes. The first of these, the rationality of control is explained in terms of the nature of the major functions involved, the ease with which they may be measured and managed, in what forms information is represented and the nature of the rationality employed. It is argued that these factors support models that exist along a continuum that extends from the use of regulative control to control based on shared understandings. The second axis reflects the locus of control and is explained in terms of the political saliency and perceived complexity of the agency's core functions, the extent to which sensegiving activities are internally and/or externally driven (Maitlis, 2005), and the extent to which management invest in the agency's public capital. These factors are used to explain a continuum on which agencies experience more or less operational autonomy and management discretion. The combination of these factors produces four possible models that may be described as: an administrative control model with a principal focus on managing inputs;  a rational goal model employing the language of (quasi) markets and a principal focus on outputs; a multiple constituency model that acknowledges the shared responsibility for outcomes and a need to establish 'joined up' mechanisms with other agencies within government and the community; and a professional service model that seeks to manage specific targets and focuses on the processes or activities that managers manage. This model is then applied to each of the case study agencies to reveal the, at times competing, forces that shape performance management practices.
Hybridisation in the Brown Alga Carpophyllum: Investigating Morphology, Distribution and Wave Exposure
Authors:   , Hodge Fiona Jean
Published: November 2021

Hybridisation can result in new hybrid lineages, parental species extinctions, the transfer of adaptations, or the merging of parental lineages. Subsequently hybridisation has important implications for the species involved. Hybridisation has recently been confirmed between the Fucalean brown algae Carpophyllum angustifolium and Carpophyllum maschalocarpum using the ITS2 marker. This study conducted a detailed morphometric analysis combined with molecular data to investigate morphology distribution and exposure at two sites on the East Cape. Hybridisation was also morphologically investigated at Leigh, where the previous work had been unable to resolve hybrids using the ITS2 marker. Carpophyllum angustifolium, C. maschalocarpum and their hybrids had distinct and intermediate morphologies, and could be identified by stipe width alone. Individuals with hybrid genotypes with distinctive C. angustifolium morphotypes were also found, which suggests asymmetrical introgression is occurring. Some aspects of C. angustifolium and C. maschalocarpum morphology were found to be correlated with wave exposure. In the more exposed zones C. angustifolium individuals were longer, while C. maschalocarpum individuals were shorter, had thinner stipes and less frequent vesicle presence. There were also nonsignificant trends of C. maschalocarpum individuals having thinner lamina, and lower branch presence in higher wave exposures. The distributions of C. angustifolium, C. maschalocarpum and their hybrids were found to be correlated with exposure. Carpophyllum angustifolium was distributed only in the relatively exposed zones, while C. maschalocarpum was distributed mainly in the more sheltered zones. Hybrids were distributed in intermediate exposure zones where both parental species were present. The hybrid distributions could be a reflection of environmental selection or of the parental contact zone. Morphological evidence was found for hybridisation at Leigh, although there were differences between the morphologies of East Cape and Leigh clusters of C. angustifolium and hybrids. These differences could be due to environmental differences, genetic differentiation or different levels of introgression between the two locations. The general findings in this study support the existing literature on hybridisation, which mainly comes from terrestrial plant and animal species complexes.
The Effects of Acute and Binge 3,4-methylenedioxymethamphetamine (MDMA) Exposure on Learning and Memory in Rats
Authors:   , Kay Charlotte Jane
Published: November 2021

When rats are administered acute doses of MDMA they produce significantly more reference memory errors than working memory errors in the partially baited radial arm maze (Kay et al, 2009). The potential role of serotonin and dopamine in this effect was examined by administering the serotonin agonist Citalopram and the dopamine agonist GBR12909. GBR12909 produced significantly more reference memory errors, while Citalopram tended to produce more working memory errors. Administration of the D1 agonist A68930 and the D2 agonist Quinpirole predominantly produced reference memory errors, but to a lesser extent than acute MDMA administration. Low doses of both drugs produced a synergistic effect, more similar to that seen with acute MDMA administration. These findings suggest dopamine plays a role in the reference memory effect seen with MDMA exposure in the partially baited radial maze. In the second half of the thesis binge regimes of MDMA (4 x 10mg/kg) were administered to rats. When there was a gap of eight weeks between dosing and training the ability to acquire the radial arm maze was not significantly impaired. When this MDMA regime was repeated with a three-day gap between dosing and training it produced a significant but transient deficit in performance. When later challenged with acute doses of MDMA (4.0 mg/kg) the binge treated rats were less impaired than saline controls indicating drug tolerance. In an additional study that used a three-day delay between dosing and training a significant impairment in task acquisition was found. This deficit appeared to be long-term as the MDMA treated rats were impaired when the rules of task were changed suggesting a deficit in cognitive flexibility. Again when subjects were challenged with acute MDMA there was evidence of drug tolerance. The final study examined the effects of repeated MDMA exposure on task acquisition by administering acute doses of MDMA or saline once a week after rats had previously been treated with either a binge regime of MDMA or saline. MDMA exposure significantly impaired task acquisition and produced residual drug effects in the binge treated MDMA group the day after acute drug administration. However evidence of behavioural tolerance in this study was mixed due to a floor effect where performance of the binge MDMA group was so poor at the beginning of the study. In conclusion MDMA exposure impaired accuracy with reference memory processes were more affected than working memory processes. The underlying nature of this impairment remains unclear but it may be due to a long-term memory deficit, an impairment in understanding task rules or a perseverative pattern of responding. These findings imply human Ecstasy users may show deficits in acquiring information and may experience deficits in cognitive flexibility
Structure and Rheology of Monodisperse and Bimodal Emulsions
Authors:   , Monahan Nicholas
Published: November 2021

Emulsions are the basis for many commercial products such as foodstuffs and paint due in part to their highly tunable flow properties. It is qualitatively understood that factors such as the dispersed phase droplet size and size distribution should affect how an emulsion flows because they influence how droplets can deform or pack. Since standard emulsification techniques such as blending and homogenization cannot produce emulsions with well-defined size distributions, little work has been done to, in particular, quantitatively determine the influence of droplet size distribution on emulsion flow properties. Consequently, in this investigation we have probed how the droplet size distribution affects emulsion flow properties by using model monodisperse emulsion systems with narrow, controllable droplet size distributions. Using a microfluidic flow focusing device, dodecane-in-water emulsions with diameters between 50 to 100 m with polydispersities less than 5% were produced, as characterized by pulsed field gradient nuclear magnetic resonance and optical microscopy. Due to the relatively large size of the droplets, it was only possible to examine the creamed phase of the emulsion. Samples of known polydispersity were made by mixing known quantities of two monodisperse emulsions. The monodisperse and bimodal emulsions were then subjected to rotational and oscillatory shear flow using a controlled stress rheometer to determine the effects of droplet size and size distribution on emulsion flow properties. Rotational and oscillatory rheological experiments showed that the monodisperse emulsions had two distinct behaviours: foam-like with appreciable thixotropy and yield stresses as well as emulsion-like with no evident thixotropy. The transition between these two behaviours appears to happen at a critical droplet radius between 33 and 37 micrometres. The rheological properties of the bimodal emulsions was split into three distinct behaviours. In samples that could be considered a matrix of large droplets perturbed by smaller droplets, the flow properties were similar to those of the constituent emulsion with the larger droplets. Increasing the number fraction of smaller droplets to a 1:1 ratio creates an entirely new phase with significantly reduced elastic properties. Surprisingly, when the emulsion primarily consists of small droplets, the flow properties are most similar to that of the large droplets. Additionally, despite the microstructural differences, all emulsions showed flow characteristics typical of soft glassy materials above the glass transition temperature. These results demonstrate the significant influence of microstructure on emulsion rheology, where altering the droplet size or polydispersity essentially creates a new phase with its own unique flow properties that is not simply a combination of the properties of the individual monodisperse components that make up the sample
Twittering Libraries: How and Why New Zealand Public Libraries Use Micro-Blogging
Authors:   , Le Gac Magalie Andree Olga
Published: November 2021

The aim of this research is to discover how and why New Zealand Public Libraries use the micro-blogging platform Twitter. This paper uses a qualitative methodology consisting of open-ended interview questions conducted via e-mail. Rogers' Diffusion of Innovation theory is used as the theoretical framework of this research. The analysis demonstrates that participants use Twitter as an alternative communication channel with members of the public who are Twitter users. Library websites as well as library services and programs are promoted on Twitter. Using Twitter enables participants to advocate for their libraries as Web 2.0 champions and is an invaluable professional development tool. The number of interactions and feedback from Twitter users who follow the library is a measure of the successful use of Twitter for participants. This research also reveals what software is being used by participants to maximise their use of Twitter. The results of this research will allow public librarians to gain more knowledge about the micro-blogging software Twitter and how it can be used to assist in the delivery of outcomes and outputs in their public libraries.
