Working towards an ideal inclusive education model for refugee background people with disabilities in New Zealand
Authors:   , Croft Lucy
Published: November 2021

New Zealand accepts up to 750 refugees per annum, with a category for refugees with disabilities, as part of its quota obligation under the United Nations Convention relating to the Status of Refugees (1957) (Immigration New Zealand, 2016). Immigration New Zealand’s Refugee Resettlement Strategy states that education is one of the main priorities with helping refugees resettle in New Zealand (Immigration New Zealand, 2013) Although there is some literature available on refugee background people and education in New Zealand, there is little focus on refugee background people with disabilities in education. This research explores how inclusive education spaces for refugee background people with disabilities could be implemented, and perceptions surrounding disability and inclusion.  In order to gain insights into the perceptions of people involved in policy or practice with refugee background people with disabilities, I used a feminist, qualitative methodology, and conducted semi-structured interviews with 11 participants who worked in education provision, non-government or government organisations that worked with refugee background people. These participants were interviewed in Auckland (n = 4), Wellington (n = 3) and Melbourne, Australia (n = 4). The Australian participants were interviewed in order to provide an alternative view to their New Zealand counterparts, although the primary focus was on New Zealand.  My findings suggest that participant perceptions of disability and inclusion generally followed social and medical models of disability, but rarely ecological. Participants who have direct experience with disability of refugee background people had more carefully constructed ideas. Based on participant answers, I developed an ideal inclusive education model encompassing physical, relational and pedagogical spaces, which could be applicable to refugee background people with disabilities. The thesis findings informs existing theoretical models and understanding of inclusive education spaces, and encourages greater inclusion of refugee background people with disabilities in education in New Zealand.
From this world to beyond: A student’s reflections on the role of her violin in music therapy
Authors:   , Ang Cheri
Published: November 2021

This practice-based research explores a student music therapist’s experiences and self-reflections on the use of her violin in supporting the elderly at a residential hospital. The objective was to find out how the violin fits in music therapy practice, where practitioners typically use the piano and guitar. Self-reflexivity was employed to increase the student’s understanding of music therapy. The two research questions were ‘why was the violin used and why not’, as well as ‘how was the violin used’. To explore these two questions in depth, a qualitative research study was undertaken, with secondary analysis of data as its methodology. The data consisted of clinical notes and reflective journals from regular practice. Thematic analysis (Braun & Clarke, 2006) was employed to analyse the data, involving a rigorous process of coding, involving both inductive and deductive methods of analysis along with graphic representations. The student music therapist, acting as both the clinician and researcher, acknowledged the influences of her musical background and spiritual inclinations on the data collected and its interpretation. Findings consisted of clients’ responses, advantages and disadvantages of the violin and the author’s relationship with the violin. A simple ‘How’ framework involving what was played on the violin and how it was played was also included. The author’s reflexivity guided a discussion that integrated the literature review, research findings and the author’s clinical and personal experiences. Drawing upon music therapy definitions and concepts, as well as philosophical ideas and spiritual teachings, answers were found to explain the role of the violin and to provide the author with a new perspective on issues of loss and dying, an understanding of the value of aesthetics and insights into her relationship with the violin.
Prioritising Medicines, Negotiating Lives: An Anthropological Inquiry of Pharmaceutical Access in New Zealand
Authors:   , Adams Veronica
Published: November 2021

Pharmaceuticals have become synonymous with ideas of health and wellbeing. The consumption of pharmaceuticals has become the gateway to restoring, maintaining, or improving one’s health; in turn becoming deeply entrenched in everyday life as treatment for disease. Given the use of pharmaceuticals for treatment, the question needs to be asked how individuals are able to obtain the medication they need. There is little anthropological literature concerning how patients negotiate and lobby for access to pharmaceutical treatment in New Zealand, particularly so in the face of Pharmac as the government entity which heavily regulates pharmaceuticals. Through conducting interviews with nine participants who are patients, general practitioners, and employees of Pharmac, I argue that in utilising policies such as cost utility analysis Pharmac prioritise which medicines are publically funded, and in doing this determine how health is conceived and calculated within the New Zealand health care system. In determining which medicines should be funded the state is making judgements over which lives are prioritised, and, in turn, who is left to die. I suggest that in the face of being denied access to life-saving drugs patients become mobilised through seeking access to experimental therapies via pharmaceutical companies. By taking these experimental treatments we come to understand that experimentation and risk have become crucial in patients fight for life against the prognosis of an early death from disease.
The performative Katherine Mansfield
Authors:   , Saker Nicola
Published: November 2021

This thesis looks at the role of performance in Katherine Mansfield’s life and its influence on her writing technique. It argues that there is a consistent thread of active engagement with performance throughout Mansfield’s life which profoundly influenced the content, construction and technique of her writing.   It is divided into three chapters. The first examines Mansfield’s early years and the cultural context of colonial, Victorian Wellington and its performance culture as well as the familial and educational influences that surrounded her.  The second chapter explores her later cultural context in London in the first decade after the turn of the century. The importance of popular culture such as music hall is examined, and Mansfield’s professional and personal performance experience is defined.  The third chapter involves a close reading and analysis of Mansfield’s dramatic techniques through the examination of the stories as well as her use of theatrical imagery, motifs, allusions and plot details.
Strategic interaction: Distrust and cooperation in US-China relations
Authors:   , Wilcox Shane
Published: November 2021

International cooperation is generally thought to be made possible, or at least enhanced, by a relationship of trust between nations. This proposition is examined with a particular focus on US-China relations, and proceeds through a critique of various models of cooperation that works to expose the limits imposed by the assumption of a causal relationship between trust and cooperation.  A concept of strategic interaction is developed on the basis of analysis of values and interests, asymmetric exchange and distrust, and is offered as an alternative to grand strategic narratives for understanding the strategic behaviour of states.
Diffuse Extragalactic Emission at Low Frequencies within the Epoch of Reionization 0-hour Field
Authors:   , Duchesne Stefan
Published: November 2021

Low-frequency radio imaging of the southern sky has become available with the advent of the Murchison Widefield Array (MWA). The topic of this thesis is the study of extended, low-frequency radio emission, with a primary focus on the non-thermal synchrotron emission associated with the intra-cluster medium (ICM) of galaxy clusters. We do not limit the study to such emission, however, and investigate a small sample of other interesting and extended radio emission from objects in the southern sky.   A significant portion of this work is invested in detecting, and characterising, extended, diffuse radio emission from galaxy clusters within a 45 degree by 45 degree region of the southern sky centred on R.A. = 0 hours, decl. = -27 degrees. This field is chosen as a deep MWA image has been made available which is sensitive to extended structures. Within the field we search for low-frequency, diffuse cluster emission, previously detected or otherwise. In doing so we find 34 diffuse radio sources, 3 of which are newly detected haloes, 1 newly detected relic with many new candidates of each. Further, we detect a new phoenix candidate as well as 2 candidate dead radio galaxies at the centre of clusters. We confirm previous observations of such emission as well, and measure properties such as their integrated flux densities, spectral indices, and sizes where possible. We compare our sample of haloes with previously detected haloes and revisit established scaling relations of the radio halo power with the cluster X-ray luminosity and mass. We find that both scaling relations are consistent with previous findings despite the increase in sample size, though note that the raw scatter in the data for best-fitting parameters increases with increase in sample size. In this, we demonstrate the utility of low-frequency radio telescopes like the MWA in detecting such emission, showing that the MWA is pushing into higher-redshift, lower-mass systems, though we caution that the low resolution of the MWA can work against us.  We follow-up on two galaxy clusters found to host extended emission - Abell S1136 and Abell S1063. In the case of Abell S1136 we observe the emission at its centre with the Australia Telescope Compact Array (ATCA) and determine the presence of a core, suggesting the emission to be that of an ancient episode of an active galactic nucleus in the central elliptical of the cluster, ESO 470-G020. After reducing archival ATCA data for Abell S1063 we find no evidence of a halo and consider the source to be constructed of blended point sources. We close with a description of a strong double-lobed radio source associated with a non-elliptical host ESO 472-G013, likely a spiral or irregular galaxy, that was found serendipitously whilst searching for diffuse cluster emission. We explore the host within the context of star-formation, and consider the possible origins of the AGN and lobes due to interaction with either the nearby spiral, ESO 472-G012, or a past or ongoing merger event.
The Female Künstlerroman in the Writing of Virginia Woolf
Authors:   , Galbraith Rebekah
Published: November 2021

The defining features of the female Künstlerroman in Virginia Woolf’s writing suggest a revision of the narrative form to accommodate, navigate, and interrogate the artist’s gender and origins of her creativity. This thesis plots the birth of the female artist and the conditions of her artistic development within Woolf’s writing by first examining the construction of Rachel Vinrace, the rudimentary artist of the equally embryonic text, Melymbrosia (1912-1982). Rachel’s failure to privately self-identify as an artist is contrasted with her reluctance to accept her future potential as a wife and mother, suggesting that “woman” and “artist” are two mutually exclusive identities. For this reason, Woolf’s use of the female Künstlerroman examines the complexities of the female artist’s ability and, indeed, inability to acknowledge and inhabit her creative identity.  But how, exactly, the narrative form develops in Woolf’s writing relies upon a reading of the relationship between the figure of the artist and the novel she occupies: Rachel Vinrace in Melymbrosia; Lily Briscoe and Mrs. Ramsay in To the Lighthouse (1927); Orlando in Orlando: A Biography (1928); Miss La Trobe and Isa Oliver in Between the Acts (1941). Each of these works present a modification of the female Künstlerroman, and, in doing so, a markedly different artist-as-heroine. Moreover, in Woolf’s later writing, the narrative development of the female artist incorporates aspects of historical non-fiction, the biographical and autobiographical, and epistolary and essayistic fictions. An analysis of the intertextual relationship between A Room of One’s Own (1929) and Orlando: A Biography, and Three Guineas (1938) and Between the Acts, is therefore critical to the argument of this thesis.  The following is an exploration of how a variety of female artist-figures are constructed within Woolf’s writing: a musician, a painter, a social artist, a poet, and a pageant-writer-director. Through Woolf’s diverse expositions on the creative process, her heroines embody the personal difficulties women encounter as they attempt to realise their artistic potential. In this way, the female Künstlerroman is used by Woolf to examine, often simultaneously, the aesthetics of failure, as well as the conditions of success. But that a multitude of creative mediums appear in Woolf’s writing suggests there are universal obstacles when the artist in question is a woman, an implication in the narrative of the female Künstlerroman that the gender of a protagonist is the primary source of complication. Therefore, the degree to which each heroine achieves a sense of creative fulfilment is dependent on her ability to recalibrate her identity as a woman with her self-authorisation as an artist.
Exploring Resettlement Impacts of Hydroelectric Projects
Authors:   , Chidmany Somsanid
Published: November 2021

Over the past five decades, there has been growing awareness of the potential negative effects of development-induced displacement and resettlement. For example, resettlement can threaten people’s livelihoods and well-being and sustainable development. In response to this phenomenon, many international financial organisations led by the World Bank have adopted safeguard policies, standards, and guidelines, especially around forced resettlement. These safeguard documents maintain that organisational and financial arrangements – through livelihood restoration programmes – can possibly alleviate displaced people’s impoverishment risks if those risks are correctly identified early. This thesis explores claims that such risks in development-caused involuntary population resettlement can be addressed by effective planning processes. Specifically, this thesis examines how resettlement and livelihood restoration programmes related to the Nam Theun 2 hydroelectric project (NT2) in Lao PDR were able (or not) to address the livelihood sustainability of resettled communities.  In conducting fieldwork in Lao PDR, this thesis employed a mixed methods approach using both qualitative and quantitative methods including semi-structured interviews, focus groups, and analysis of quantitative and qualitative secondary data.  The key findings found in this study reflect NT2’s mixed performance of resettlement. On the one hand, the project provided enormous advantages to Lao PDR: a) the cooperation between Lao government and international stakeholders including resettled people in the preparation of resettlement strategies; b) introducing the Lao government and resettled people to a new global standard of resettlement practice. On the other hand, this project also caused a number of challenges: a) incomplete preparation of the resettlement strategies; b) unsuccessful implementation of livelihood restoration programmes; and c) the lack of precision in terminology – stipulated in the CA – to enable the effective establishment of measures, indicators and criteria which could be used to inform objective and fair decision making. These findings seem to hold NT2 back from successfully achieving the sustainable development for resettled people’s livelihoods and well-being.  The findings of this study should be of interest to development academics and practitioners working in the fields of energy development and development-induced displacement and resettlement. Specifically, the lessons learned from resettlement and livelihood restoration programmes implemented by Nam Theun 2 hydroelectric project are crucial, because it is considered a role model for other hydropower projects in Lao PDR. It is hoped that the results of this study can make a contribution to the on-going improvement of the Lao government’s existing policies on resettlement and livelihood restoration strategies in order to fulfil sustainable development goals.
Reflexivity in the negotiation of participation: Insights from a culturally-embedded community project in Vietnam
Authors:   , Nguyen Nguyen Hai Duy
Published: November 2021

This research aims to explore the possible negotiation of participation within development practice in Vietnam based on different understandings of reflexivity among different development actors. Specifically, it adopts a qualitative approach, using a sustainable community livelihoods project in Central Vietnam as a case study, to ask the following questions: (1) How do Western and local development facilitators understand reflexivity in participatory development in Vietnam?; and (2) How do Western and local development facilitators negotiate and practice reflexivity in participatory development in Vietnam?  These questions are important because while participation and fieldwork partnerships in community projects promise mutually-beneficial opportunities for shared learning, they also involve negotiations of power. The reflexivity of development practitioners assumes that they can obtain thorough understanding and knowledge of the local culture and facilitate participation appropriately, which may not actually be the case. Secondly, little is known about how participants think or practice their own culturally-embedded understandings of reflexivity in their interactions with non-local practitioners. Thirdly, there is a knowledge gap about how participation intersects with reflexivity as “Western” development discourses and local understandings are negotiated.  Semi-structured interviews were employed with three groups of people positioned differently within the case study project: international development practitioners, Vietnamese development practitioners and local community members. Interpretative methods of auto-ethnography and reflexive writings were used to analyse the researcher’s own understandings of reflexivity and the working of power from his prior work as a translator in this project.  Building on existing critiques of reflexivity, and through careful analysis, the thesis interrogates assumed links between reflexivity and better facilitation in community projects. The negotiations explored in this research include rethinking the principle of reflexivity in the context of local cultural norms as these significantly shape values of development work and likely benefits for practitioners and participants. From extracted perspectives of research participants through semi-structured interviews and the researcher’s reflections by means of auto-ethnography, an alternative approach is suggested to aid development practitioners in reflecting upon notions of “self” and “others” in order to examine various conceptions of participation in theory and practice.
The Composer's Hand: An Analysis of Selected String Orchestral Works by Arvo Pärt
Authors:   , Johnson Mark
Published: November 2021

Arvo Pärt’s music has received little attention from theoretical scholars, in part, because it is often labelled as minimalist or process music. This is due primarily to his use of limited sets of musical materials and predetermined repetitive melodic and rhythmic procedures. In this sense, it is implied that authorial decisions play little role in the compositional process of his music. In addition, the confluences of multiple M-voice/T-voice pairings, which create a rich array of harmonically non-functional chord progressions, do not lend themselves to traditional approaches to musical analysis, thus acting as a further deterrent to analysts and theorists.  This investigation postulates that the presence of the ‘composer’s hand’ is much more significant in Pärt’s music than has been previously realised by those who label his music as minimalist or process music; and by engaging in a multimodal methodology, this thesis demonstrates that Pärt’s music does, in fact, respond to post-tonal analytical approaches. It also shows that a non-traditional application of post-tonal analytical techniques can yield valuable and productive insights into Pärt’s compositional system, and that there is actually much for theorists and analysts to discover in his music.  The approach to the investigation is based on drawing from and combining several post-tonal analytical methods, any one of which would be insufficient on its own, given the uniqueness of Pärt’s sound world and the fact that such approaches have been developed to enlighten very different repertoires. The methodology incorporates the following post-tonal analytical methods: descriptions of the ‘musical fabric’ of each work; a detailed analysis of how each composition appears to have been constructed; new approaches to visualising the relationships between the pitch classes of particular works; and mappings of each work’s pitch-class and interval-vector content.  This investigation demonstrates, through multimodal analysis of six selected string orchestral works by the composer, that hidden beneath the seemingly ‘minimal’ surface layers of Pärt’s music are carefully crafted musical constructions that result from intersecting procedures and multifaceted rules, as well as what appear to be intentional exceptions to those rules – thus revealing the composer’s hand. An awareness of these hidden constructions and the careful craftsmanship that went into their creation can provide the informed listener with the critical foundation from which the aesthetic value of Pärt’s music can be assessed and appreciated.
Iron-TAML Complexes: A Computational Approach to Improving Stability
Authors:   , Tuano Kevin
Published: November 2021

Researchers at the Institute for Green Oxidation Chemistry of the Carnegie Mellon University developed a group of catalysts called tetra amido macrocyclic ligand (TAML) activators. The purpose of that research was that TAML activators would breakdown pollutants in the presence of a sacrificial oxidant. Furthermore, the catalyst was designed to decompose on a required timescale, as to not damage the environment by prolonged exposure. Since the initial designs from the 1980’s, the TAML structure has undergone significant changes to increase efficiency or selectivity. Other uses of this group of catalysts have been explored, namely, the oxidation of water to molecular oxygen.  This work presents a computational study using Density Functional Theory (DFT) which addresses the issue regarding the stability of certain iron-TAML intermediates in the water oxidation mechanism. Hence, the work seeks to explore how changing certain groups on the TAML ring can affect the stability of the reactive intermediates and the activation energy of the nucleophilic attack within the mechanism. The work highlights the importance of the fluorinated tail of the TAML structure in the accessibility of the desired transition state.
Quantitative PCR Analysis of the Bartonella henselae carD Gene during Bacterial Stress
Authors:   , Simmonds Jacob
Published: November 2021

The Bartonella genus is comprised of arthropod-borne, intracellular bacterial pathogens that colonise the mammalian bloodstream. A large number of mammalian species are hosts for one or more Bartonella species, as either reservoir or incidental hosts. Bartonella species are only able to invade and replicate in host red blood cells in the reservoir host, and to be taken up by an associated haematophagous arthropod vector to complete transmission and the bacterial life cycle. Humans are the reservoir hosts for B. quintana and B. bacilliformis, and are incidental hosts for more than 16 additional zoonotic Bartonella species, including B. henselae, which is normally carried by cats. B. henselae infection, usually acquired through cat scratches or bites, can result in several clinical manifestations, with varying degrees of severity; the most common of these is cat scratch disease, where symptoms commonly range from enlarged lymph nodes to severe fever. Although usually a mild illness, B. henselae infection can occasionally lead to severe symptoms, affecting neurological and other major organ systems.  During their life cycle the Bartonellae must adapt to various toxic host environments; such adaptation is mediated by several bacterial stress pathways, which modify bacterial transcription. However, many gaps remain in the understanding of B. henselae stress response pathways. The object of this study, the carD gene, was identified as a possible component of the Bartonella stress response. The carD gene has been shown to be critical for stress defence in other bacterial species, including Mycobacterium tuberculosis, Thermus thermophilus, and Myxococcus xanthus.  Our study aimed to investigate whether carD played as significant a role during the B. henselae response to stresses as it does in other bacterial genera. We first attempted to perform growth comparisons between a B. henselae carD mutant strain and a wild type strain during exposure to stress conditions; however, our mutagenic carD plasmid interfered with bacterial growth of Escherichia coli cultures, which hindered transformation and generation of a B. henselae carD mutant. As an alternative, we investigated the expression of B. henselae carD under stress conditions, comparing carD expression during stress against a non-stressed B. henselae control, using quantitative PCR. We found no significant difference of expression of the carD gene between the control and any of our conditions, although a trend of increased carD expression was found in several stress conditions. We believe that these findings merit further study into the role of carD in the B. henselae stress response.
Part of The Whānau: The Emergence of Takatāpui Identity - He Whāriki Takatāpui
Authors:   , Kerekere Elizabeth
Published: November 2021

Since the early 1980s, Māori who are whakawāhine, tangata ira tāne, lesbian, gay, bisexual, trans, intersex or queer have increasingly adopted the identity of ‘takatāpui’ - a traditional Māori term meaning ‘intimate companion of the same sex.’ As the first study on takatāpui identity and well-being, this is fashioned as a Whāriki Takatāpui; a woven mat which lays the foundation for future research and advocacy. Kaupapa Māori research provides the tools for this task while Kaupapa Māori theory ensures the harvest of Māori narratives is underpinned by te reo, tikanga and mātauranga - Māori language, culture and knowledges. The preparation of weaving materials is represented by Mana Wāhine; which considers whakapapa (genealogy), intersectional colonial oppression with an artistic approach to analysing whakataukī (historical metaphor). Mana Motuhake represents the design of the Whāriki; the colours and patterns emanating from the subjective experiences of six leaders who have embraced a takatāpui identity. Te Whare Tapa Whā represents weaving together takatāpui health and well-being in response to the issues and discrimination they face. Oral history interviews were held with takatāpui participants who reflected a diversity of iwi, geographical location, gender identities and sexualities and, at the time of interview, ranged from 17 to 68 years of age. In order to gain insight into the perception of whānau with takatāpui members, semi structured interviews were also held with two kuia (female elders) and 12 whānau members of the takatāpui rangatahi (young people) interviewed. In total 27 participants were interviewed in three stages over four years. Their responses were recorded, transcribed then analysed based on the elements of the Whāriki Takatāpui framework. Despite colonial efforts to remove historical trace, this study reveals new evidence of takatāpui behaviour within traditional Māori narratives. It finds that takatāpui identity is predicated on Māori identity with a spiritual connection to takatāpui tūpuna (ancestors) that is crucial in addressing the discrimination they may face within their whānau and culture. It identifies the range of issues that impact on takatāpui health and well-being while highlighting the creative and strength-based manner in which takatāpui build resilience and connection through identity.
Constructing childhood for children : an analysis of 1970s award-winning children's literature from the Children's Model Collection at Auckland City Libraries
Authors:   , Baker Sanya Karen
Published: November 2021

Childhood is not simply a personal experience of an individual human in their early years of life. It is also a social construct which governs the way a society treats its youngest members – if they are considered to be members yet at all.  Children’s literature is an acknowledged source of information about the ideologies adults have both intentionally and unintentionally offered children to help them understand the world and their place in it.  This research involved both content analysis and discourse analysis of award-winning children’s books from the 1970s, which form part of the Children’s Model Collection held at Auckland City Libraries. These books, considered by local librarians to be ‘model literature’ for New Zealand children to read, were used as a window onto the constructions of childhood in this society at that time.   Traditional children’s literature in English supported particular relations of domination through certain ‘institutions’ of childhood – family, friendship, gender, race and religion. The 1970s books also imparted ideologies through these institutions along with themes of land, coming of age and war; all interacting under a humanistic umbrella. Through their treatment of these themes or ‘institutions’, texts in this sample often deliberately challenged traditional relations of domination – with varied levels of success. Children were constructed as leaders in waiting, the hope for the future; a future where tolerance and respect would overcome prejudice, thinking for one’s self would replace conformity and the individual could be the best they could be. However, underlying linguistic mechanisms and ideologies transformed many of these texts into conservators of the very relationships they were intending to change.  The methods of analysis used in this project were successful in locating the ideologies in books created for young people and revealing the degree to which these are agents of their time. These methods then are both eminently suitable for future research and would be a valuable addition to the multi-literacies with which we equip young people
Ecology of the Possum (Trichosurus Vulpecula Kerr) in the Karori Water Supply Reserve, Wellington, Sounds Ecological District
Authors:   , Stoffregen Hans
Published: November 2021

The abundance and condition of possums in various areas of the Karori Reserve, Wellington - Sounds Ecological District was assessed. Possums were most abundant in the upper part of the reserve in an area dominated by bishop and radiata pines with an undergrowth of native species and in an area dominated by gorse and flax shrublands. In the lower part of the reserve, possums were less abundant and there a number of characteristics were observed: possums had a higher body weight for age, their reproductive output was higher and the population was marked by a higher proportion of females and juveniles. This was interpreted as a "compensatory response" characteristic of possum populations maintained at low densities. Possum stomachs were sampled in spring and their contents analysed in order to investigate the importance of Fuchsia excorticata and other plant species to possum diet. In the lower part of the reserve the leaves of Fuchsia excorticata and the flowers of Cytisus scoparius made up more than 50 percent of the possums' forage. In the upper part of the reserve exotic species such as the flowers of Cytisus scoparius and Ulex europeans as well as the leaves of native species such as Aristotelia serrata, Pseudopanax arboreus and Coprosma robusta made up the bulk of possum forage. Exotic plants accounted for a significant proportion of the spring possum diet in the reserve. Whereas most leaves originated from native plants, the exotic species contributed mainly carbohydrate-rich flowers and pollen. The canopy condition of two possum-susceptible tree species Fuchsia excorticata and Pseudopanax arboreus was assessed early in autumn over the years 1993, 1995 and 1996. Over these years, 47 percent of marked fuchsia trees were completely defoliated and most trees are unlikely to recover even if possums are eradicated from the reserve. All defoliated fuchsia trees were located in the upper part of the reserve. On the other hand, 37 percent of marked fuchsia trees exhibited only a little possum damage. Most of these trees were located in the lower part of the reserve where possum density was lower. Increasing possum densities could therefore be correlated with an increasing level of possum damage to fuchsia canopies. Even though Pseudopanax arboreus leaves and petioles were encountered in 10 percent of possum stomachs, the canopies leaves and petioles were encountered in 10 percent of possum stomachs, the canopies of assessed trees did not seem to be greatly affected. It appeared that due to the high abundance of this plant species in the reserve the effects of possum browse were spread over the whole reserve to levels which could be tolerated by an individual Pseudopanax arboreus tree.
Who is 'New Zealand'? Publics in Aotearoa/New Zealand General Election Discourse
Authors:   , Anderson Ian
Published: November 2021

2011 saw the lowest voter turnout in Aotearoa/New Zealand since women won the right to vote (Vowles, 2014). This decline in participation aligns with trends elsewhere in the Anglosphere (Ailes, 2015; Hansard, 2015). This organic crisis poses new questions for notions of the ‘public sphere’ and ‘publics’ – the forms of political engagement with citizens in a mass-mediated society. Fraser (1990) contends that in theorising the “limits of actually existing late capitalist democracy” (p. 57), we need a notion of pluralised and contesting ‘publics’ (ibid). The project asks how political parties named the 'public' (or publics) in the 2011 and 2014 Aotearoa / New Zealand General Elections. In order to consider the dominance of these political articulations, research will also consider whether these invocations of 'the public' found coverage in the national press. This is not intended as a sociological examination of actually existing publics, but an examination of dominant encoding (Hall, 2001). This analysis tests the thesis that dominant cross-partisan electoral discourses defined the 'public' in terms of dual identification with productive work and capital, in opposition to named subaltern publics. This formulation suggests that workers are called to identify with capital, following from Gramsci’s (2011) theorisation of bourgeois hegemony. Research begins with a content analysis of party press releases and mainstream coverage during the 2011 & 2014 General Elections, when official discourses hailing 'the public' are intensified. Content analysis quantifies nouns used for publics – for example, 'taxpayer', 'New Zealander', or even 'the public'. From this content analysis, the project proceeds to a critical discourse analysis, which seeks to historically contextualise and explain the patterns in content. Reworking Ernesto Laclau's (2005a) theorisation of populism to factor in the left/right axis (which Laclau considered outmoded), this critical discourse analysis considers what 'public' alliances are articulated, and what political programmes these articulations serve.
Hungry for Progress? Enacting Food Sovereignty
Authors:   , Kula-Kaczmarski Natasha
Published: November 2021

This research builds upon and utilises an emerging field of food and development theory – food sovereignty – as it discusses possibilities for an alternative food system, where the production, distribution and consumption of food may be guided by principles that foster a holistic, ethical and sustainable approach.  The theory of food sovereignty has grown from the writings of La Via Campesina (a global movement of food producers in the Global South) and offers critiques of the current food system, food security and corporate globalisation. As I grapple with the key principles of food sovereignty and explore the ways in which they are visible within Wellington, Aotearoa, I interact with five key organisations and present ways their actions foster a food sovereignty paradigm. By blending the theoretical with the practical, this thesis presents the lived experiences of people working in; Koanga Institute, Biofarm, Commonsense Organics, Workerbe and Kaibosh.  Bringing together the perspectives of these five organisations with relevant literature, this thesis first discusses some potential market-based solutions for achieving ethical consumption. It then examines ideas around the move to ‘grow something’ as a tool for resistance, reclaiming spaces and healing; to finally explore the ways in which a more holistic approach to food can nurture spiritual connections in profound and unique ways.  Hungry for Progress? Enacting Food Sovereignty is a qualitative research project that embraces notions of positionality and reflexivity and shares my journey of living this research. Through exploring the food sovereignty narratives and worldviews, I seek to promote empowerment among individuals and organisations through constructing knowledge that supports postcolonial, feminist and activist interactions so that good change in the food system (and beyond) may become a reality.
A Paleoclimate Reconstruction of the Little Ice Age to Modern Era Climate Conditions in the Eastern Ross Sea, Antarctica as Captured in the RICE Ice Core
Authors:   , Brightley Hannah
Published: November 2021

The Little Ice Age (LIA) (1400-1850 AD) represents one of the most significant climatic shifts over the past 5000 years. Previous studies from Antarctica indicate generally cooler and stormier conditions during this period, but this pattern shows distinct spatial and temporal variability. The Roosevelt Island Climate Evolution (RICE) ice core provides a new opportunity to study the drivers behind this variability at annual/seasonal resolution, in a relatively under-sampled and climatically sensitive region in the eastern Ross Sea. Contrary to previous studies, isotope measurements suggest warm conditions during the LIA at Roosevelt Island.  This study presents analysis of eight major ions (Na⁺, Mg²⁺, Ca²⁺, K⁺, MS⁻, Cl⁻, NO₃⁻, SO₄²⁻) using both Ion Chromatograph and ICP-MS data, in order to reconstruct the atmospheric circulation pattern, sea ice extent and marine primary productivity across this LIA to Modern Era (ME) at Roosevelt Island. The dataset is tied to a robust age model allowing annual dating and the opportunity to accurately reconstruct rates of change during this ME-LIA. Challenges revolving around the calibration of the Ion Chromatograph are also discussed. The major ion record determines whether the lack of cooling in the Roosevelt Island core implied by the stable isotopes represents a true temperature anomaly or whether the atmospheric circulation pattern caused an isotopic enrichment that masks an underlying cooling.  It was determined that Roosevelt Island experienced during the LIA (i) an increase in marine air mass intrusions along with weaker katabatic winds compared to the 200 years prior, (ii) decreased biological productivity and (iii) increased sea ice. From the 1850-1880s to 1992 AD, there is a shift to reduced marine winds, increased katabatics, increased biological productivity and decreased sea ice until 1992. In the wider Ross Sea context, this suggests an east-west divide in terms of the dominance of katabatics versus marine wind influence. This divide is attributed with the warming signal seen in the RICE record in the Eastern Ross Sea and the cooling in the Western Ross Sea records. It is also likely linked to the influence of climate indices on the depth/position of the Amundsen Sea Low.
The development of science epistemology in senior science courses: A quantitative study

Epistemological development is a pivotal aspect of liberal education because the ability to distinguish between knowledge and pseudo-knowledge and the ability to use the particular methods of reasoning associated with various disciplinary fields equips people to make judgements in complex issues. The present study examines the extent to which studying each of the different science disciplines in secondary years 12 and 13 supports the development of science epistemology. A further aim was to determine the relationship between epistemological development in science and the completion of inquiry-type coursework. Data were collected from 735 year 12 and 13 students from 11 schools, mainly from the Wellington region. A survey, designed for this study, comprised statements about the nature of science and scientific argumentation conceptions, two pivotal aspects of science epistemology. Using a quasi-experimental design, this quantitative study explores the extent of the development of science epistemology over a year of studying science, by comparing students’ scores in Term 1 with scores in Term 3 on the instrument.  The findings showed a more advanced epistemic view among science students; however, a positive effect of science studies on epistemic development was not evident. It was concluded that a greater emphasis on authentic inquiry is essential for epistemic development and, while understanding of the philosophical assumptions underpinning scientific knowledge is important, this should arise from authentic science inquiries – or the processes of science – rather than being taught in isolation from the practice of the discipline of science. This leads to a question the extent to which an emphasis should be placed on the ontological aspects of the philosophy and the sociology of science, potentially at the expense of developing sound understanding of science epistemology.
A Novel System for Monitoring in vivo Cell Signaling Pathways Involved in Early Embryonic Patterning
Authors:   , Rooney Louise
Published: November 2021

Early developmental events, such as the arrangement of the head-tail axis, are fundamentally driven by cell signalling cascades. Such incidents are regulated in a highly complex manner by promoters and inhibitors at many levels of the cascade. This complexity makes it difficult to understand where and when certain signalling occurs, and what effects additional factors have on the signalling system. Nodal signalling, executed by intracellular Smad2/3 signal propagation, is thought to induce the anterior-posterior and head-tail patterning of the early mouse embryo. Target gene outputs of this signalling are fine-tuned by a vast array of modulators; TGBβ co-receptors, extracellular ligand and receptor inhibitors, DNA binding cofactors, and intracellular enhancers and inhibitors. The endogenous target genes of this system cannot be used as a measure of signalling as they themselves feedback on the original system and others, creating diverse signals. In this body of work, we have distilled the Nodal signalling cascade to a single variable by creating a fluorescent genetic reporter to semi-quantitatively measure Smad signalling during early embryonic development. Reporter constructs contain Smad binding elements, a minimal promoter and fluorescent protein elements. Various sensitivity Smad binding elements were created to respond to different thresholds of signalling. Fluorescent microscopy and flow cytometry were used to verify responsiveness of reporter constructs, tested first in a mouse embryonic fibroblast line and subsequently in transgenic embryos. This study will provide an understanding of how extracellular cues dictate gene expression during early embryonic formation. The knowledge acquired from this work may have implications in dairy cattle and human fertility.
Three Essays on Capital Structure
Authors:   , Yaghoubi Mona
Published: November 2021

This thesis consists of three self-contained essays about the relationship between cash flow and investment volatility and firm capital structure and cash holdings. Capital structure measures sources of financing that allow a firm to operate, invest, and grow.  The first essay reviews the theoretical relationship between firm capital structure and cash flow volatility, develops testable hypotheses, constructs a data set, and then tests the hypotheses using several measures of firm cash flow volatility and econometric methods that account for the non-linear relationship of proportional variables. Overall, the evidence indicates that ceteris paribus, a one standard deviation increase from the mean of cash flow volatility, implies approximately by 24% decrease in the long-term debt ratio, a 26% decrease in probability of holding debt with over 10 years to maturity, and a 39% increase in the probability of not holding either short or long term debt. These findings are novel in the empirical capital structure literature and show the importance of cash flow volatility in firm financial policies.  The second essay studies the financing behaviour of Hospital Corporation of America (HCA) from 1990 to 2013 and demonstrates variation in HCA’s market and book leverage ratios due to 1) mergers and acquisitions and divestitures that change the firm’s total assets, 2) share buybacks, and 3) leveraged buyouts and public offerings that change the firm’s ownership. The paper scrutinizes variation in HCA’s market and book leverage ratios independently as well as relative to each other. Our evidence shows that i) HCA’s management team used HCA’s excess cash from divestitures to repurchase HCA’s stock rather than pay off HCA’s debt, ii) HCA’s market leverage ratio tends to stay in a target leverage zone, and iii) in some years HCA’s management team used the book leverage ratio as a tool to keep the market leverage ratio inside a target leverage zone.  In the third essay, we investigate the influence of investment volatility on capital structure and cash holdings using a broad definition of investment. Despite theoretical motivation, the relationship between investment volatility and capital structure has not been studied in the empirical literature. All in all, our evidence suggests that i) firms with relatively high capital expenditure and acquisition investment volatility hold relatively higher levels of debt and lower levels of cash, ii) firms fund large capital expenditures and/or acquisition by increasing debt or decreasing cash, and iii) immediately after funding large investment firms reduce debt levels and increase cash holdings. Research and development investment volatility is related to lower debt levels and higher cash levels, and does not exhibit similar investment spike funding. Overall, our results are consistent with parts, but not all, of the DeAngelo, DeAngelo and Whited (2011) model.
