    Since 1960s, a large number of researchers have focused on how organisations have made large investment to streamline their supply chain to improve customer satisfaction and increase their internal productivity, all with the aim of achieving a competitive advantage against competitors on the market. Much research has been conducted on lean management techniques, aiming to reduce the costs of supply chains by minimizing their length and agile management aiming to increasing the robustness and flexibility of supply chains. An emerging field of research combines the two principles indicating that an organisations success lies in the combination of both. This is the case in the consumer electronics industry. The consumer electronics industry generates an array of products and services increasingly used in nearly every human endeavour, now deeply entwined in our social fabric, electronic products and systems now support critical aspects of communication, education, finance, recreation, and government. In the past few years, China in particular have become increasingly important in the consumer electronics as well as other industries. As an importer to New Zealand, a market for consumer electronic goods has been rapidly amplified over the years introducing a market for more relevant companies to be established and the market competition to become more competitive. This research focused on the implementation of lean, agile and leagile strategies in four consumer electronic retail companies from China and New Zealand. It is aim of this research to better understand the inner supply chain management strategies and practices of these four companies, and analyse how these strategies improve their supply chain performance. Finally, the research will find out what New Zealand’s companies should learn from China’s successful companies by comparing these strategies and identifying the environments these four companies operate in. This research will aim to uncover characteristics associated with the success of Chinese consumer electronics companies, specific to lean, agile and leagile strategies and see whether New Zealand has the infrastructure to gain the same competitive advantage using these strategies.

  • Identification of biomarkers of colitis to monitor effects of dietary omega-3 polyunsaturated fatty acids in the interleukin-10 gene-deficient mouse model of inflammatory bowel diseases : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Nutritional Science at Massey University, Manawatū, New Zealand

    Inflammatory bowel diseases (IBD) are characterised by chronic inflammation of the gastrointestinal tract including the colon (colitis). Increased dietary intake of salmon, which is rich in eicosapentaenoic acid (EPA), was well tolerated by IBD patients, leading to a perceived decrease in symptoms. However, better knowledge of the mechanisms by which EPA-rich diets affect IBD severity, and appropriate biomarkers for assessing these effects, are needed for potential targeted nutritional interventions. This dissertation aimed to determine the temporal effects (early (9 weeks of age) vs. established (12 weeks)) of a diet containing 3.7% EPA, and the dose-dependent effects (15% to 45%) of a salmon diet at 12 weeks of age, on the severity of colitis. Molecular responses in colon and/or liver of the interleukin-10 gene-deficient (Il10-/-) mouse model of IBD and healthy mice were assessed. Caecum digesta, urine and blood were mined to identify biomarkers (microbiota, metabolites and genes) of these responses. The EPA diet reduced the severity of colitis only in 12-week-old Il10-/- mice. This response was associated with changes in gene expression associated with lymphocyte function, eicosanoid signalling and peroxisome proliferator-activated receptor gamma signalling. The blood immune cell gene expression profile did not correlate with reduced colitis in these mice, but the urine metabolite profile was related to changes in colonic tryptophan metabolism. The effects of the salmon diets on colitis were dose-dependent in 12-week-old Il10-/- mice. The intermediate amount of salmon (30%) reduced the severity of colitis and lymphocyte-related gene expression, while enhancing genes in metabolic pathways. Tryptophan metabolism was not affected in these mice, but the urinary metabolite profile correlated with effects on hepatic tocopherol metabolism, as shown by reduced abundance of gamma-carboxyethylhydroxychroman glucoside. The abundances of V. akkermansia, Eubacterium spp., and an unclassified Rikenellaceae were further affected in these mice. This is the first report describing molecular responses in the colon and liver of Il10-/- mice fed a salmon diet associated with reduced colitis. Ultimately these responses could be validated for use in humans, and potentially enable management of IBD with diet.

  • Shear work induced changes in the rheology of model Mozzarella cheeses : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Food Technology at Massey University, Manawatu, New Zealand

    Mozzarella cheese is a pasta filata type of cheese. Its manufacture includes a kneading – stretching step that creates a fibrous protein network and distributes fat-serum channels to attain desirable melt functionality on a pizza. During processing and manufacturing of pasta-filata cheese, large deformations take place. For appropriate characterization of a food material, rheological evaluation should be conducted in similar operating conditions, length scales and time scales to those taking place in the actual process. Development of the typical fibrous pasta-filata structure of mozzarella cheese depends on composition and process variables. Critical process variables in the development of cheese structure are time, temperature and shear. In this study we studied the effect of shear work on rheology, structure and melt functionality of model Mozzarella cheese. Three types of model cheeses (full-fat, non-fat and full-fat with added tri-sodium citrate) were prepared by working cheese components together at 70 oC in a twin screw Blentech cooker. Varied amounts of shear work input (2.8-185 kJ/kg) were given to the cheese samples using 50, 150 and 250 rpm screw speeds. Samples were subjected to a range of rheological tests, confocal laser scanning microscopy, fat particle size measurements (DLS) and melt functionality evaluation. While measuring steady shear viscosity of Mozzarella-type cheeses in a rotational rheometer at 70oC, three main difficulties were encountered; wall slip, structural failure during measurement and viscoelastic time dependent effects. A flow curve method was successfully devised to measure steady shear rheology by using serrated plates as surface modification to avoid wall slip, giving enough measurement duration at low shear rate to avoid viscoelastic effects and selecting limited shear steps to cause minimum structural changes. These techniques enabled successful measurement of steady shear viscosity of molten Mozzarella-type cheeses at 70oC at shear rates up to 250 s-1. Strong work thickening was observed for full fat Mozzarella cheese from steady shear rheology, oscillatory rheology, creep, elongational viscosity and tensile testing data. Steady shear rheology and melt functionality were found to be strongly dependent on total shear work input. An exponential increase in consistency coefficient (K from power law model) was observed with increasing amounts of accumulated shear work, indicating work thickening behaviour. An exponential work thickening equation is proposed to describe this behaviour. Excessively worked cheese samples exhibited liquid exudation, poor melting and poor stretch. Nonfat cheese exhibited similar but smaller changes after excessive shear work input. At lower shear work inputs (70 kJ/kg) it behaved like a viscoelastic solid with low frequency dependence. A definite critical point for structural and viscoelastic transition was identified at a medium shear work level (~ 58 kJ/kg at 150 rpm). Similar viscoelastic property changes occurred in non-fat cheese suggesting that major changes were taking place in the protein matrix during working. Confocal microstructures plus macroscopic observations showed systematic changes in structure with increased shear work inputs with unmixed buttery liquid observed at 58 kJ/kg. At very high shear work inputs, > 75 kJ/kg, striations or anisotropy in the microstructures had disappeared and small micro-cracks were evident. Volume-weighted mean fat particle size decreased with shear work input and particle size distributions also changed. To account for the short and long term relaxation response behaviour, a 4-element Burger‘s model was found adequate for fitting the creep data of model cheese at 70 oC but a 6-element model was required at 20 oC. As shear work input increased, retarded compliance decreased and zero shear viscosity increased indicating the more elastic behavior of the cheeses with higher shear work input. Fracture stress and strain for longitudinal samples from elongated full fat cheese did not vary significantly with shear work input up to 26.3 kJ/kg then decreased dramatically at 58.2 kJ/kg. Longitudinal samples with shear work input G‘ > elongational viscosity > consistency coefficient, K. It was concluded that the dominant contributor to the changes in rheology, structure and melt properties with increased shear work was shear induced structural changes to the protein matrix. An increase in calcium induced protein-protein interactions after high shear work at 70 oC. In summary, this thesis provides useful insights to shear work induced changes in material properties. It proposes useful linkages between the manufacturing process and the application of model Mozzarella cheese using appropriate rheological methods. Since the linkages were validated for only one composition and in only one processing environment, it is proposed that they should be tested in other conditions. In order to build a more complete picture, a molecular level study is proposed for future work to elucidate chemical changes during working and find appropriate linkages with physical and functional characteristics.

  • A prelimiary descriptive epidemiology study on angular limb deformities in a sample of commerical New Zealand thoroughbred foals : A thesis submitted in partial fulfillment of the requirements for the degree Master of AgriScience (Equine) Massey University, Palmerston North, New Zealand

    A prospective observational study was carried out to provide descriptive epidemiology of angular limb deformities (ALD) at several predetermined time-points in a sample of Thoroughbred foals born during the 2013/14 breeding season across five commercial North Island Thoroughbred stud farms. The stud farms selected were a convenience sample based on geographical location, annual foal crop and their willingness to partake in the study. Data were collected for foals scored at birth, foal heat (2 weeks), 6 weeks, and weaning age (approximately 5 months). Foals were examined for the presence of angular deviations at the carpal, tarsal and fetlock joints; these were graded on a scale ranging from 1-5 in severity between 0 and 20, which was quantified using an ALD measuring limb protractor designed for the study. Foals were also examined for the presence of offset carpal joints and rotational deformities of the cannon and pastern regions. A total of 230 foals were scored for the presence of ALD at birth. Overall, 78% (180/230) were recorded to have one or more ALD at birth. This was significantly more than at foal heat (71%; 39/55), six weeks (29%; 18/55), and weaning age (12%; 30/257) (p< 0.001). A total of 363 ALD were recorded at birth, 66% (239/363) were recorded as severity score 2. Angular limb deformities with severity scores 3 and 4 were recorded less frequently (31%; 112/363); there were no ALD with severity score of 5 recorded throughout the trial. There was no significant association of overall occurrence of ALD to gestation length, mare age and foal gender. Inter-observer agreement on the presence and severity of ALD was strong between study personnel and fair between study personnel and stud staff, (k = 0.75, 95% CI) and (k = 0.27, 95% CI) respectively. The greatest source of disagreement was in the scoring of mild ALD, and ALD at the carpal joint. Disagreement was attributed to a low number of simultaneous scorings between study personnel and stud staff, and the dynamic effect that changes in stance and maturation of foals during the first days post-partum have on the perception of ALD and severity. Data for the management of ALD were recorded for 27% (71/265) of the foals scored with ALD over the course of the trial. Management of ALD across all stud farms involved a period of conservative management before any surgical interventions. Confinement (39%; 86/222) and hoof trimming (28%; 62/222) were the most frequently recorded methods of early intervention. Surgical interventions (5%; 12/222) were reserved for foals with severe ALD and those with ALD that had not responded to a period of conservative intervention. Across all stud farms treatments were tailored to individual foals, highlighting the dynamic nature of foal development.

  • The Invention of Papahurihia : A thesis submitted in fulfilment of the requirements of the degree of Doctor of Philosophy in History at Massey University, Albany, New Zealand

    Ward, Judith (2016)

    Doctoral thesis
    Massey University

    Historians portray Papahurihia as the first Māori prophet and founder of a syncretistic religion that combined elements of Judaic and Christian theology with Māori beliefs. They also say he observed a Saturday Sabbath and that his followers were known as Jews. This thesis disputes those conclusions. It re-examines the commentaries of the CMS missionaries in the Bay of Islands from the context of 1830s Protestant evangelicalism and draws on the texts of the Wesleyan and Roman Catholic missionaries and European settlers to show how Papahurihia behaved in various situations. It argues that historians have failed to take account of the way that Protestant and Catholic writers saw Papahurihia through the lenses of their own religions. The thesis recreates Papahurihia in the context of the Ngāpuhi seasonal cycle and links him to the persistence of ceremonies like the hahunga. It argues that historians have overlooked the extent to which he operated on a Māori concept of time and how the missionaries and Europeans made assumptions about the behaviour of Papahurihia and his followers based on the Christian calendar. The thesis concludes that Papahurihia responded to the advent of Christianity in a way that was consistent with the behaviour of tohunga at the time, rather than as the founder of a syncretistic religion. It also concludes that the historiography on Papahurihia ultimately went awry because historians interpreted the missionaries’ comments about him from a secular perspective.

  • Taxonomies of Taiwanese Aboriginal Musical Instruments

    Cheng, Lancini Jen-hao (2015)

    Doctoral thesis
    University of Otago

    This research aims to discover the indigenous taxonomy systems of Taiwanese aboriginal instruments. This is a cross-cultural investigation providing a panoramic perspective on the musical instruments of Taiwanese aborigines (Austronesians). The term ‘musical instrument’ is used in its broadest sense to refer to all sound-producing instruments in this research. There are many reasons for undertaking this research. For example, until now, few people have known what forms of aboriginal musical instruments have existed throughout the island of Taiwan, and there has been little scholarly discussion about their indigenous names and classifications. The original contribution of the research is its ethnographic fieldwork component, which results in new information concerning indigenous instruments and taxonomic schemes from the opinion of 48 cultural insiders across 17 different aboriginal groups in Taiwan. The researcher’s approach is based on participant observation - by recording the musical activity in either traditional or contemporary contexts, and by interviewing cultural insiders about their traditional music. Also, the researcher analyses the instrumental form, function and meaning of aboriginal instruments across synchronic and diachronic development. The findings in this dissertation provide a new understanding of many unknown musical instruments from different aboriginal groups (e.g. Bunun, Kavalan, Pazih-Kahabu, Puyuma, Rukai, Sakizaya, Siraya and Tsou). This investigation also makes original contributions to extend the instrument type and the numerical entry of the Hornbostel-Sachs system of musical instrument classification. Moreover, this dissertation provides a link between Taiwanese aboriginal instruments and other Austronesian musical instruments. In summary, the many factors that influence indigenous taxonomies of Taiwanese aboriginal instruments include linguistic factors (onomatopoeia, overlapped radicals, and the verbalising affix), how they are played, the materials used in their construction, their performance contexts, as well as players’ gender, social status and religion.

  • One Pot Double Network Hydrogels: Progress Towards Synthesis of Applicable Crosslinking Agents

    Sutherland, Peter Hugh (2015)

    Masters thesis
    University of Otago

    Our work initially looked at the possibility of being able to synthesis a double network hydrogel in just one free radical polymerisation. We intended to carefully select three compounds based on their copolymerisation reactivity under free radical conditions. This reactivity would generate a tightly cross-linked network first, followed by a loosely cross-linked network in one process. The hypothesis was tested by a Monte-Carlo simulation which showed that this two network state was achievable with known reactivity ratios. This work primarily focuses on the synthesis of novel cross-linkers based on N-vinyl pyrrolidone (1). This monomer has the necessary copolymerisation ratios with methyl methacrylate for this project, so simple difunctional analogues of 1 were designed. The synthesis and purification of these analogues proved not to be straightforward, and in the end only very small amounts of a suitable material were obtained. While the idea has merit, new ways of synthesising the key cross-linker still need to be found.

  • "Square girls" : Prostitutes and prostitution in Dunedin in the 1880s

    Lucas, E Heather (1985)

    Honours Dissertation thesis
    University of Otago

    The study of prostitutes and prostitution in New Zealand has usually been subordinate to a more general analysis of women and crime. As prostitutes were, and still are, regarded as criminals in New Zealand, this has been a valid approach. However, prostitution was a particular sort of crime, in that it was essentially a crime against middle class morality. As a consequence, a study of prostitution, in itself, not only allows a fuller appreciation of the nature and extent ,of prostitution in New Zealand, but also an insight into the social structure and attitudes pertaining to sexuality and morality in colonial New Zealand.
