Isolation of New Secondary Metabolites from New Zealand Marine Invertebrates
Authors:   , Wojnar Joanna M 
Published: November 2021

<p>This study describes the isolation and structure elucidation of several known and 13 new compounds from New Zealand marine organisms. Furthermore, it describes the development of a digital mask program for the analysis of HSQC spectra of crude sponge extracts. This was used as a screening tool to identify secondary metabolite producers that warranted further analysis. As reports of metabolites from New Zealand nudibranchs are poorly represented in the literature, a study of five New Zealand nudibranch species was undertaken. These coloured and seemingly undefended nudibranchs are known to concentrate or sequester toxic metabolites from their prey, facilitating rapid isolation and structure elucidation of these metabolites. This study resulted in the isolation of a variety of metabolite classes; two new compounds, 13alpha- acetoxypukalide diol (30) and lopholide diol (31) from the nudibranch Tritonia incerta, are described. Examination of the sponge Raspailia agminata resulted in the isolation of a novel family of partially acetylated glycolipids which contain up to six glucose residues. The chromatographic separation of these compounds was a challenge due to the similarity of the congeners and their lack of a chromophore. MSguided isolation eventually led to the purification of agminosides A-E (145-149). An unidentified sponge of the order Dictyoceratida was found to contain a new isomer (186) of the known sesterterpene variabilin. As variabilin-type compounds are predominantly found from sponges of the family Irciniidae, the unidentified sponge is most likely an irciniid. In addition, the sponge contained two prenylated quinones, one of which, 189, is a new isomer of a known sponge metabolite. The sponge Darwinella oxeata contained four new nitrogenous diterpenes of the aplysulphurane (rearranged spongian) skeleton, oxeatamide A (214), isooxeatamide A (215), oxeatamide A 23-methyl ester (216) and oxeatamide B (217).</p>
Seeing God and the Poetry of Ursula Bethell
Authors:   , Flinn Marit 
Published: November 2021

<p>Mary Ursula Bethell's poems are almost exclusively celebrations of natural beauty. What, then, is the significance of the beauty within the world to the poet? This question is central to Bethell's poetry and this thesis attempts to answer it. Beauty, for Bethell, is the invisible shining through the visible. It is the glory of God shown in the physical world. As Bethell searches for and celebrates beauty, she is in fact searching for and celebrating the face of God. Bethell's first collection, From a Garden in the Antipodes, introduces the role of beauty in the poet's life: a role of revealing the world as a point of connection between herself and her God. Time and Place continues with this theme. Here the focus is on Christ as the ultimate Being - the foundation of all things, who is revealed most perfectly through the beauty of the world. Day and Night holds the climax of the revelation of God. It unveils the Holy Spirit as the 'Spirit of Beauty', so creating a direct link between the poet and her God - a link which is made evident by the beauty of the world.</p>
Emergency Department Re-Presentations Following Intentional Self-Harm
Authors:   , Kuehl Silke 
Published: November 2021

<p>Repeat intentional self-harm (ISH) episodes are strongly correlated to suicide. Intentional self-harm for this thesis includes suicide attempts, deliberate self-harm and suicidal ideation. The aim was to describe what factors contribute to people re-presenting to the emergency department (ED) within one week of a previous visit for intentional self-harm. Objectives identified were to describe the people using demographic and clinical features; describe and evaluate ED management; and identify possible personal or system reasons as to why people re-present to ED within one week. A retrospective observational design was selected for a period of one year. The data was collected from electronic clinical case notes. The sample consisted of 48 people with 73 presentations and re-presentations. Descriptive and inferential analyses were undertaken using the Statistical Programme for Social Science (SPSS). Missing data limited the number of inferential analyses. Outcome measures were divided into information regarding the person and the presentation. This study made several discoveries: many representations (55%) occurred within one day; the exact number of people who represented many times to ED is unknown, but is far higher than reported in other studies; fewer support people were present for the second presentation; the documentation of triage and assessments by ED staff was often minimal, though frequently portrayed immense distress of this population; cultural input for Maori was missing; physical health complaints and psychosis were found with some intentional self-harm presentations; challenging behaviours occurred in at least a quarter of presentations; and the medical and mental health inpatient admission rates were approximately 50% higher for second presentations. Recommendations in regard to the use of a triage assessment tool, the practice of reviewing peoples' past presentations and the need for a mental health consultation liaison nurse in ED are made. Staff education, collaboration between services with consumer involvement and further research of this group are required. This study supports the need for holistic and expert care for people who present ED with intentional self-harm. Such care needs to be provided in a safe way with the intent on reducing the distress experienced by people who intentionally self-harm.</p>
Pacific Community Mental Health Nurses' Experiences of Working for a District Health Board in New Zealand
Authors:   , Apelu Jacinta 
Published: November 2021

<p>As meeting the mental health needs of the Pacific people living in New Zealand has become a major focus for providers and District Health Boards since deinstitulisation, so is the significance of mental health care delivery for the Pacific minority. Pacific community mental health (PCMH) nursing as a means of healthcare delivery is a fairly new and unknown practice domain. The fact that no studies have been carried out to explore nursing in this field makes this an area that requires an understanding. This understanding will, in turn, enhance knowledge embedded in PCMH nursing and helps reduce practice constraints. This study explored the perspectives of Pacific nurses on what it is like for them to work in a PCMH service within a District Health Board. Five Pacific Island nurses who worked in the three Pacific Community Mental Health services based in the Auckland region participated in the project. The study employed narrative inquiry to gather data through focused storytelling method. The results of the study have indicated that PCMH nursing is a unique nursing field as well as highlight significant practice issues for nurses. Complex service infrastructure and language have been found to be the major contributing practice constraints. The findings suggest the need for District Health Board authorities, Pacific Mental Health service management, professional nursing education and development programs to consider addressing these practice issues to prevent further increase in the problem of PCMH nurses shortage and enhance recruitment and retention of these nurses.</p>
Exploring Transitions: Working in "the Space Between the no Longer and the Not Yet"
Authors:   , Clayton Janice Ruth 
Published: November 2021

<p>This thesis uncovers a personal journey of reflective practice in Aotearoa / New Zealand. The focus for reflection is on my emerging role as a nurse facilitating transitions using a dialectical approach in the context of a private nursing practice. Transitions encompass: life changes, loss, and adjustment to changes in function. Dialectical nurse facilitation of transition (DNFT) is a way of exploring self in the transitional space between "the no longer and the not yet". In this facilitated process people potentially discover paradoxes, tensions, and creative energy, as they search for a way forward. The research design details a dialectical heuristic quest through journaling and reflecting on practice supervision and peer review, over a two year period. Exemplars written after reflecting on case notes reveal the lived experiences of participants Sophie, Grace, Rose, Faith, Lilo, and Charles (pseudonyms). These case reviews show the complexity of patterns for people undergoing transitions and nurse facilitation. A relational pattern for DNFT encompasses compassionate engagement, catalytic mirroring, and interconnectedness. A transitional pathway from impasse to transformation shows itself as the people I work with search for clarity about the nature and meaning of self. The transitional pathway is mirrored in practice supervision and peer review in my search for professional clarity and grounded-ness. This reveals a mutual transformational process going beyond the boundaries of feelings and reason, into the regions of the human energy field and spiritual essence of self. This integral approach finds resonance with nursing, Buddhist, and psycho-social philosophies and theories that posit human beings as the embodiment of spiritual energy. An exploration of literature encompasses nursing theories, facilitation, dialogue, loss, grief, spirituality and transition. These show how the patterns that I find, both resonate, and are divergent from extant knowledge. This thesis sheds light on the often hidden aspects of reflection and nursing practice and may support professional and personal growth. It also provides a basis for evaluative research on the effectiveness of DNFT in health care settings in the future. Discussions regarding the expansion of these reflective and praxis genres are included which may be of interest to nursing education and practice contexts.</p>
Teacher Perceptions of Information and Communication Technologies in a Secondary School in Samoa
Authors:   , Afamasaga-Wright Farita Tepora 
Published: November 2021

<p>This study explored teacher perceptions of information and communication technologies in one secondary school in Samoa, in order to gain insight into recent government initiatives to introduce computers and other ICTs in schools. Phenomenology as an approach was deemed appropriate to the focus of this research in that it provided the framework for an in-depth exploration of how teachers view themselves within a particular event in the development of education in Samoa: the integration of ICTs in schools. Underpinning this study were assumptions about the nature of knowledge as being socially constructed as well as contextually situated. The research sought understanding of the phenomenon from the perspective of one group of participants. Data was gathered using lengthy semi-structured interviews in the Samoan language which were then translated into English for the purpose of data analysis. Significant findings include: lack of clarity amongst teachers regarding ICT in education policies, government rationale and strategies to achieve policy; teacher rationale for the introduction of ICT in schools included improvement of teaching and learning, student future employment and improved student access to technology. Teacher perceptions of ICT were mostly positive noting that its use contributed to higher levels of student interest, engagement, independent learning and motivation. As well, ICTs were mainly used to support teacher-centred pedagogies and contributed to the efficiency of teacher preparation. While teachers were keen to use ICTs in their classes, they were hindered by lack of ICT skills and insufficient pedagogical knowledge. Teachers perceived several obstacles to effective integration of ICTs in classrooms, which included: insufficient student and teacher access to computers; timetabling restrictions; a user pays system; maintenance and running costs; student plagiarism from the web and access to inappropriate sites as well as inadequate teacher professional development for the use of ICTs. ii</p>
Novel Multidimensional Inverse Laplace Nuclear Magnetic Resonance Spectroscopy Techniques
Authors:   , Washburn Kathryn Elizabeth 
Published: November 2021

<p>This thesis presents the new development and application of multidimensional inverse Laplace nuclear magnetic resonance spectroscopy techniques. We present a new NMR technique which relates the longitudinal relaxation rate of the NMR signal to the internal gradients in the sample. We perform the experiment on a large range of magnet strengths to provide experimental evidence for the theory of how internal gradient intensity scales with pore size as a function of field strength. We make the first attempt of quantisation of two dimensional inverse Laplace experiments. We perform a transverse relaxation exchange experiment on several samples for a range of mixing times. We then integrate the peaks in the resulting spectra and plot them as a function of mixing time. By fitting the experimental results to theory, we can estimate the molecular exchange between pores of differing sizes. We then modify the transverse relaxation experiment to include diffusion attenuation so that we can see the separate signals for oil and water. We use this to look at the effect wettability has on the movement of the different fluids between pores. We then present the first experiment to combine two inverse Laplace dimensions with a Fourier dimension. We add a propagator dimension to the transverse relaxation exchange experiment to measure how far the molecules move during the mixing time. Quantisation of the results allows us to estimate the exchange rate between pores of similar sizes in addition the exchange rate between pores of different sizes. We are also able to estimate pore radii, inter-pore spacing and tortuosity. Lastly, we attempt a three dimensional inverse Laplace experiment by correlating transverse relaxation, diffusion, and internal gradients. While the three dimensional inversion techniques require more development, the results show resemblance to those seen from two dimensional experiments.</p>
Cognitive Underpinnings of Symbolic Pretend Play and Impossible Entity Drawings: Imaginative Ability in Typical Development and Autism Spectrum Disorder
Authors:   , Den-Kaat Steven 
Published: November 2021

<p>The individual differences in imagination ability in children with autism spectrum disorder (ASD) were tested in a sample of 14 children with ASD and 14 matched typically developing (TD) children. Analysis was conducted on the extent of imagination in symbolic pretend play and impossible entity drawings. Aside from difficulties with imagination, children with ASD showed significant group deficits in executive function (generativity, visuospatial planning and cognitive flexibility) and false belief theory of mind understanding. Amongst children with ASD, executive function abilities (generativity and visuospatial planning) related to imaginative play and drawings. In contrast, amongst participants in the TD group, a mixture of both executive function (cognitive flexibility) and false belief theory of mind understanding predicted imaginative ability. These results are discussed in terms of how executive control plays a broad and important role in imaginative ability across groups, but the contributions appear to be expressed and routed differently in ASD. The discussion also highlights the theoretical implications of not having theory of mind that underpin imagination in ASD.</p>
The Direct Growth of Carbon Nanotubes and Its Substrate Dependence
Authors:   , Munro Chris 
Published: November 2021

<p>The unique combination of light weight, small dimensions, structural diversity, excellent mechanical strength and remarkable electronic properties make carbon nanotubes an attractive field of discovery for a wide range of applications, from reinforcing materials to molecular sensing. The immediate problem is in reliably and reproducibly fabricating carbon nanotubes and nanotube arrays with a certain exclusive structure. The reason for this is the large number of parameters integral to nanotube growth. This thesis describes the effect of several synthesis parameters - including temperature, catalyst, and water addition - on the growth of carbon nanotubes by a thermal chemical vapour deposition method. In all instances, multi-walled nanotubes were the only carbon nanotube products observed. The chemical vapour deposition method employed here involves hexane as a volatile carbon precursor and ferrocene as a floating catalyst. The hexane is introduced into the system by passing a stream of nitrogen carrier gas through a bubbler containing the carbon precursor, while the ferrocene catalyst is positioned inside the working tube where it can evaporate gradually. The products of this method are large, vertically aligned arrays of clean multi-walled nanotubes. The second part of this thesis describes the role of the supporting layer in affecting the growth of these extended nanotube arrays. A number of substrates have been examined - both conducting and non-conducting - and the products from these were analysed. It was found that all non-conductive, metal oxide substrates used - these included quartz, alumina, glazed porcelain, Pythagoras, and also fluorite - produced extended fields of carbon nanotubes. Conversely, many conductive substrates - including nickel, molybdenum, glassy carbon, highly ordered pyrolitic graphite and nickel-iron-silicon metal alloys - produce only small amounts of carbon nanotubes. This difference is likely caused by the deactivation of the iron catalyst at high temperature due to diffusion into the substrate surface.</p>
