- Description: The research described in this thesis investigated the microencapsulation of omega-3 oil and probiotic bacteria together in a protein-polysaccharide complex coacervate matrix. The synergistic or competitive interactions between the probiotic bacteria and omega-3 fatty acids when packaged in a single microcapsule was determined including how best to utilise such interaction to achieve improved oxidative stability of omega-3 fatty acid and better survival of the probiotic bacteria. Encapsulation and co-encapsulation of tuna oil (O) and Lactobacillus casei 431 (P) as models of omega-3 and probiotic bacteria, respectively, were carried out and the works is described in this thesis in five distinct sections. (1) The optimisation of the complex coacervation process between whey protein isolate (WPI) and gum Arabic (GA). (2) Microencapsulation of tuna oil (O) in WPI-GA complex coacervates followed by spray and freeze drying to produce microcapsules (WPI-O-GA). (3) Microencapsulation of probiotic bacteria L. casei 431 (P) in WPI-GA complex coacervates followed by spray and freeze drying to produce microcapsules (WPI-P-GA). (4) Co-encapsulation of omega-3 oil and L. casei 431 together in WPI-GA coacervate matrix followed by spray and freeze drying to produce co-microcapsules (WPI-P-O-GA). (5) In-vitro digestion evaluation of co-microcapsules and microcapsules to indicate bioavailability. The viability of L. casei was significantly higher in WPI-P-O-GA co-microcapsules than in WPI-P-GA microcapsules in both spray and freeze dried microcapsules. The oxidative stability of tuna oil was significantly higher in spray dried co-capsules. Also, co-microencapsulation increased the survivability of L. casei during simulated digestion. There was no significant influence observed on the release properties of omega-3 oil due to co-microencapsulation. However, the total omega-3 fatty acids in the released oil during in-vitro digestion were found to be higher, when co-microencapsulated. Hence, co-microencapsulation was shown to protect the L. casei and deliver both viable cells and omega-3 oil to human intestine without any significant adverse effect on their functionality and properties.

- Description: Perseverance is a quality which individuals draw on to achieve their goals, despite any challenges they may face, and so is one of the keys to academic and life success. Perseverance is considered to be a positive attribute that can be learned. In this study, how tertiary students understand perseverance, how they acquired it and its role in their lives and learning are explored. The research sample for the study consists of nine pre-service teachers from Initial Teacher Education (ITE) in regional Victoria, Australia. The researcher uses semi-structured interviews, and draws on educational and salutogenic theory and a qualitative methodology. The data has been analysed within the Ecological framework based on the work of McLeroy and colleagues (1988). In the introductory chapter the aims of the study are outlined, perseverance is defined and its significance as a character strength/ attribute is considered. The second chapter, the literature review, explores the extent to which perseverance, along with associated character strengths, has been identified as a significant factor that influences educational achievement and the ability to meet life’s challenges. The third chapter provides justification for applying a qualitative phenomenological methodology, with particular attention to describing both the salutogenic theoretical perspective and the Ecological Model (EM). The fourth chapter, the data analysis, identifies themes within the data and these are discussed with reference to the relationships between the EM layers. The fifth chapter offers the discussion, implications and conclusion of the study. The research findings indicate that all the participants defined perseverance as an attribute or character strength which they called on to overcome challenges and obstacles as they pursued their goals. They associated it with such qualities as persistence, motivation, commitment, focus, goal-setting and strength, amongst others. They recognized perseverance as integral to their academic success as well as to their ability to manage crises and challenges in their lives. They identified multiple contributors to their acquisition of perseverance, including family members, friends and some teachers. Many of the participants identified instances when they made a conscious decision to persevere, and viewed the experience as definitive in their growth as mature people. However, few of the participants considered the schools they attended to have played a significant role in developing their understanding of perseverance or of helping them acquire it, though they were appreciative of those teachers who gave them general support and encouragement. They recognized the importance of schools and teachers explicitly teaching perseverance and supporting its development through positive critique and feedback, and of students experiencing multiple opportunities for practising perseverance at the individual, family, school and policy levels. In educational practice, these conclusions suggest that further research into how best to implement these approaches across all schools would be invaluable.

Innate-like T cells in patients with cancer

- Description: Innate-like T cells, including invariant natural killer T (NKT), mucosal associated invariant T (MAIT) cells or g T cells are associated with regulation of anti-tumour responses in humans and mice, although their exact role remains controversial. We have studied innate-like T cells from tumour infiltrating lymphocytes (TILS), peripheral blood mononuclear cells (PBMCs) and bone marrow (BM) derived cells from patients undergoing treatment for cancer and compared their characteristics to cells from healthy donors. We identifed that the overall frequency of innate-like T cells was variably deficient in patients with blood or solid cancers. Interestingly, the deficiency of innate-like T cells appeared to be more severe than that of other T cells suggesting a specific impact. An increased proportion of activated g T cells and MAIT cells suggested they could have a functional role in responses to cancer cells. Despite the deficiency of these subsets in patient tissue samples, we showed that anti-tumour capacity of innate-like T cells was intact as innate-like T cells in most patient groups had a similar cytokine response to stimulation as cells from healthy donors. Finally, we also showed that innate-like T cells appeared not to broadly recognize cancer cells, as no direct impact was identified in their overall frequency or cytokine expression when exposed to autologous tumour cells, cancer lysates or lipids extracted from patient tumours, or colorectal cancer cell lines. This project was aimed at providing an overview of potential defects in innate-like T cells based on my analysis of a wide range of samples in the Fiona Elsey Cancer Research Institute (FECRI) Tissue Bank. As a result of my studies, we have established a clear understanding of innate cells in cancer, which provides a basis for future studies. Our novel findings include analysis of frequency distribution and functional capacity of MAIT cells in solid tumours other than colorectal cancer and in patients with blood cancers such as chronic lymphocytic leukaemia (CLL), non-Hodgkin's lymphoma (NHL), multiple myeloma (MM) or other haematological malignancies, something not previously reported. Taken together, we showed that a deficiency of innate-like T cells is common in patient groups with cancer and could be a risk factor for disease and possibly a target for immunotherapies, but the functional capacity was intact for cytokine responses.

Dr Fanny Reading : 'A clever little bird'

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis is the biographical study of the ‘transnational’ life of Dr. Fanny Reading (1884-1974). Dr Reading came to live in the Ballarat area c. 1888 when she was four years old. Originally she was born in Karelitz near Minsk, Russia as Zipporah Rubinovitch. The thesis tells the story of her transformation and also the story of her family members because they were a close-knit orthodox Jewish family. Reading’s biography is of a migrant woman who belonged to a persecuted minority group, and who through force of character rose above the challenging circumstances of her birth. It serves to redress the fact that historically she has been overlooked. It confirms that at a grassroots level she mobilised the Jewish women of Australia and was a significant Jewish leader. As a transnational figure of considerable stature, Reading’s biography contains themes of place, class, gender, ethnicity and diaspora that are woven throughout the thesis. It covers her early childhood and adolescence in Ballarat, then her move to Melbourne early in the twentieth century where she became involved in Jewish youth activities and taught Hebrew at the St Kilda Jewish Congregation. The family name was changed to Reading about 1919. Reading entered the University of Melbourne firstly to study music and then medicine (M.B., B.S.1922.) After graduation, she went into general practice with her eldest brother, who was also a doctor, in Sydney. Inspired by a Zionist emissary Bella Pevsner, Reading founded the Council of Jewish Women in 1923. This organisation became the National Council of Jewish Women in 1929. Reading had a keen interest in the health and education of women and girls, the Hebrew language and Israel. She was held in high regard in both the Jewish and non-Jewish communities and received an MBE in 1961.

Kemo Sabe : Tonto as a developing construction of the Indian character type
- Authors: Moll, Nicholas
- Date: 2014
- Type: Text , Thesis , PhD
- Full Text:
- Description: At the opening of each episode of The Lone Ranger radio series, audiences are invited to “return with us now to those thrilling days of yesteryear”. From 1933 through to 2013 productions of The Lone Ranger media franchise have continued to extend this invitation. The evocation of the past through The Lone Ranger franchise includes Tonto: the masked man’s Indian sidekick. Tonto has remained an element of the franchise since the inception of The Lone Ranger and the development of Tonto presents an intriguing map of changing Indian characterization across the twentieth-century. This study argues that Tonto has developed as the masked man’s foil to incorporate colonial violence and Anglo-American culpability into The Lone Ranger narratives. In doing so, this thesis notes that Tonto’s assimilation within narratives of The Lone Ranger can be read like a parable, presenting a model of appropriate social responses for the interrelation of races through the masked man and Tonto’s partnership. The structure and style of Tonto’s assimilation develops gradually in the franchise over the course of the twentieth-century. Initially Tonto’s assimilation suggested a Romanticized future for the Indian following colonization. However, later productions of The Lone Ranger juxtapose assimilation with extermination. In analysing the development of Tonto, this thesis examines six features of the character. The first three are foundation concepts consisting of the idea of the Indian, the Western genre and franchise theory and development. The second three are constant facets of characterization comprised of Tonto’s status as an Indian, the recurring theme of Manifest Destiny in The Lone Ranger texts, and the growth of Tonto parallel to activism of the 1960s and 1970s. This thesis contributes to knowledge as the first study of Tonto as an ongoing development rather than a static characterization discussed in broad terms.

Intelligent sewer blockage detection system using Internet of Things
- Authors: Buurman, Benjamin
- Date: 2019
- Type: Text , Thesis , Masters
- Full Text:
- Description: Despite being a common issue in both developed and developing countries, wastewater blockages have severe potential consequences. Blockages can be located at sewer mains or individual properties and can also be classified as partial or full. Full blockages completely obstruct a wastewater asset, and partial blockages will often develop into full blockages if left unattended. Currently, blockages are managed by routine manual inspections to wastewater assets on a round-robin schedule. This is highly inefficient and costly, as blockages that form between these inspections and progress to effluent breaches will go undetected. In this thesis we present an Internet of Things (IoT) solution capable of simultaneously monitoring an entire wastewater infrastructure for blockages while still remaining inexpensive, reliable, and practical. Wireless motes use float switch sensors to detect blockages and transmit this to a central system using either LoRa or Wi-Fi communications. Making both LoRa and Wi-Fi available ensures the system can be adapted in any situation across a variety of geographic and economic restrictions. The central system determines whether a surcharge is caused by a blockage or simply the result of regular activity not requiring intervention. Detection of false positives is critical, as deployment of field technicians is an expensive process that moves resources from other skilled work. If a surcharge is determined to be caused by a blockage, the central system will classify it as full or partial before estimating the property or length of main between properties it is located at. Following this, relevant parties will be notified so field technicians can be deployed to resolve the blockage. We performed both practical laboratory testing and simulation modelling on our proposed system, and confirmed it is indeed capable of detecting, classifying, and locating blockages across a wide urban area. Our choice of hardware, software and network equipment ensures that the proposed IoT-based solution is inexpensive, workable, and easily deployable.

A hand made wood object : Studio investigation into transformed nature

- Description: This research explores the importance of retaining traditional hand skills in terms of their relevance to contemporary and future art practice. I examine the hand made and the process of transforming timber into a wooden sculptural form. I investigate how the artist thinks with the material, and how this process gives the artist the ‘sight’ to identify new and original possibilities. Furthermore, I explore how the transformative approach perpetuates new knowledge, and how skills are modified and adapted to suit the changes. I describe this as a dialogic process. The research examines the correlation between the transformative process and the hand made object, the imprint of the maker and how their memories of the processes used, remain embedded in the object. In addition, this research investigates the transformation processes used in creating an object, to provide individualisation within our highly mechanised world, while providing a bridge connecting the past and the future. Through the examination of traditional hand skills, I demonstrate how such skills provide an anchor, a standard of quality and artisanship that connects artists from traditional wood practice, through contemporary praxis, to hand made digital art. My research focuses on the transformation process and traditional hand skills, the vital role they play in the creation of digital hand made objects; as digital processes utilize new materials, processes and machinery that interfaces with traditional analogue tools.

Firm growth by women-owned Small and Medium Enterprises in a developing economy setting

- Type: Text , Thesis , PhD
- Full Text:
- Description: The growth experiences of women-owned Small and Medium Enterprises (SMEs) in the context of a developing economy are examined through the lens of pragmatism. This approach views a businesswoman’s ‘belief’, ‘habit’ and ‘doubt’ as critical for researching gender related issues in entrepreneurship. This study explains the growth aspects of women-owned manufacturing and services SMEs of Bangladesh with the aim of addressing two neglected research issues. One is the scarcity of studies on growth oriented women entrepreneurs in developing countries. The other is the lack of focus on very successful high-growth women-owned firms in the context of a strong male-dominated economy. This study adopts a framework developed out of the Diana International Project to evaluate the factors influencing the growth of these successful, growing, Bangladeshi women-owned businesses. In order to evaluate the growth process itself, this framework was then modified with growth resources and actions as explained by Edith Penrose in her 1959 seminal book The Theory of Growth of the Firm. This allows for the investigation of the effects of managerial and entrepreneurial abilities in growth, and the identification of how firms achieve growth. A multiple-case design is adopted, covering sixteen successful growth-oriented firms in the manufacturing and services sector. SMEs were studied as the basis for firm growth from initial venture creation, while the sector concentration on manufacturing and services reflects the urban nature of the study in examining firms that exist in the capital city of Dhaka. Data from in-depth interviews and supporting documents were used for the case studies and integrated with the theoretical framework. Themes were categorised and patterns compared against the framework. The results of this research suggest that SME growth is a process which is gradual and iterative, comprising a series of growth strategies and approaches. The framework identifies interactive connection between different growth variables and highlights how industry sector and the national context of a growing economy facilitate growth of women-owned SMEs. The case study based research seeks to advance scholarship in relation to women’s entrepreneurship globally and contribute to the understanding of growth oriented women’s entrepreneurship. Building upon existing knowledge, this research endeavours to generate new insights and advance theoretical discourse by providing richness and subtlety to the knowledge of growth process and opening up new avenues for future research.

The cultural interactions of Aborigines with Whales, Whalers and Whaling in southwest Victoria 1828-1850
- Authors: Eldridge, Richard
- Date: 2015
- Type: Text , Thesis , Masters
- Full Text:
- Description: The primary aim of this thesis is to reconstruct the history of Aboriginal cultural associations with whales and whaling in southwest Victoria in the nineteenth century. Despite there being a considerable corpus of information about Aboriginal peoples and whaling in southeast South Australia and southern New South Wales, there is a relative poverty of information on southwest Victoria. One of the primary objectives of this thesis is to offer explanations for this absence of information. Through an analysis of the Convincing Ground massacre that is believed to have taken place in the early period of whaling at Portland Bay, it will be argued that the violence characterised by this event fundamentally transformed race relations at Portland to such an extent that Aboriginal people avoided interaction with whalers. The rationale for this research is twofold: first to contribute to the history of frontier relations in Victoria; second, to reconstruct from archival sources the cultural and economic associations between Victorian Aboriginal people and whalers.

Investigations into the ecology and management of the invasive plant Galenia pubescens within the native temperate grasslands of Victoria, Australia
- Authors: Mahmood, Ako
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Plant invasions of natural ecosystems are one of the major threats to the conservation of biological diversity across nearly all biogeographical regions in the world. This thesis focuses on Galenia pubescens (Carpet weed) as a case study of possible approaches to the potential management of environmental weed species. G. pubescens is a woody prostrate perennial plant that is becoming a serious threat to Australian temperate grasslands, surrounding agricultural areas and conservation reserves. It is indigenous to South Africa and was first recorded in Australia in the early 1900s, and it is an aggressive competitor against native species. It is difficult to control, and little information exists about its effects on natural ecosystems, and aspects of its biology and ecology. This study has investigated some important ecological characteristics of G. pubescens’ seeds and has experimented with different management strategies in combination with chemical control. It has also considered the potential for the expansion of the distribution of this species across suitable habitat in Australia under predicted elevated CO2 and drought conditions. Seeds of G. pubescens are shown to be able to germinate over a broad range of temperatures, but short bursts (5 minutes) of high temperatures (80oC to 120oC replicating possible exposures to a fire) reduced seed germination. Seed germination was positively favored by light and declined rapidly in darkness, decreasing by > 80% at a depth of only 0.5 cm in soil. This suggests that fire regimes might be useful in removing mature plants and controlling seed numbers on the surface, and that subsequent native seeding of undisturbed areas may assist in the long-term management of this noxious weed. A trial was conducted to determine the effect of treatment with a plant essential oil (pine oil) to limit the seed germination and seedling emergence of G. pubescens. This trial showed that the effects of pine oil application were significant (P<0.05). Germination was completely inhibited by application of pine oil at 5% or higher concentrations directly to seeds, and seedling emergence was reduced by between 90 and 100% in pot trials. These outcomes demonstrate the potential viability of pine oil as a long-term control option for this species. In field-based experiments, control strategies including herbicide control with glyphosate, organic herbicide control with pine oil, the application of mulch, and the addition of native seeds to the available seedbank (and all possible combinations of these techniques), were tested. The study showed that one single treatment of a G. pubescens infestation without undertaking a secondary treatment is insufficient to control the G. pubescens infestation or to encourage native regeneration, but that a combined strategy, employing all the aforementioned techniques, is more effective. It is however suggested that full regeneration of the area may not be possible unless further restoration programs are instituted after the cycle of G. pubescens’ treatment has been completed. The thesis also assessed the control effects of chemical control combined with a prescribed spring burning. Assessment of the resulting aboveground vegetation of G. pubescens has shown that a combination of chemical control and late-spring burning can reduce the cover of non-native species such as G. pubescens, suggesting that this could be a useful tool in their management. Finally, this study has supported the view that the growth of G. pubescens will be significantly enhanced in a future climate with an enriched atmospheric CO2 concentration. These climatic changes will have important implications for management of this noxious weed in the future.

Assessing productive soil - landscapes in Victoria using digital soil mapping
- Authors: Robinson, Nathan
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Spatial soil information is used to support questions on agriculture and the environment from global to local scales. Historically, soil mapping has been used to inform and guide a multitude of land users with their decisions. Demand for specific spatial soil information is increasing in response from a wider range of users operating across agricultural and environmental domains. To satisfy these demands, users must be provided with practical and relevant spatial soil information. Novel approaches are required to deal with global deficiencies in available soil information. A major limitation to this is the plethora of incongruent legacy data with poor spatial and temporal coverage. This research study initially identifies the specific needs of users for spatial soil information with a focus on the requirements of biophysical modellers. Secondly, error sources that hamper Digital Soil Mapping (DSM) are identified, described and assessed using pH in practical and relevant examples. A final aim is to spatially predict soil properties (e.g. clay mineralogy) that underpin soil chemical behaviour. This is achieved by harmonising legacy data in combination with new spectroscopy techniques and a spatial inference approach. The spatial soil information needs of biophysical modellers in Victoria, Australia were found to be consistent with global needs for information including soil water characteristics, organic carbon and effective rooting depth. To accommodate stochastic and epistemic uncertainties in spatial soil information, uncertainty frameworks proved effective to deal with, and understand the limitations of legacy data in spatial inference models. Robust and reliable spectroscopic models for properties that are linked to functions and services delivered by soil were achieved and used in 3D spatial models. These findings will enable a tactical response through the delivery of pertinent spatial soil information that is contemporary, quality assured and sought by users. Learnings presented should enable producers of spatial soil information to be more comprehensive in their delivery of products that are easy to use, accessible and understood by a growing user community.

The contribution of silverfish (insecta: zygentoma) to Australian invertebrate biodiversity and endemism
- Authors: Smith, Graeme
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: Silverfish (Order Zygentoma) are quite abundant in Australia but have been largely overlooked. This thesis examines the biodiversity of the Australian fauna at the level of genus, describing at least one representative species from each named genus and some new genera. The endemism of the fauna is evaluated and likely zoogeographic origins proposed. Over 4000 specimens were examined, either collected by the author, borrowed from or examined within museum collections or supplied by organisations and individuals conducting fauna surveys. Twenty- seven new native species are described and two redescribed, bringing the number of named species recorded in Australia to 74. Five new genera are described and four additional genera recorded in Australia for the first time including autochthonous representatives of three subfamilies previously unrecognised as native to Australia (Acrotelsatinae, Lepismatinae and Coletiniinae). No representatives of the families Maindroniidae, Tricholepidiidae and Protrinemuridae were found. The subfamily Acrotelsatinae was redefined following a revision of the enigmatic genus Anisolepisma Paclt, 1967 with the unique structure of the thoracic sterna identified as diagnostic for the subfamily. Contrary to existing opinion, it is suggested that this is a fundamentally different and plesiomorphic character, rather than an apomorphic reduction of the free thoracic sterna. A monograph of the Australian Zygentoma is presented, including a summary of the biology of the order, a key to and diagnoses of the genera, as well as information on the known habitat and distribution of each genus and a discussion of their zoogeography. At the suprageneric level the fauna is less diverse than seen in other zoogeographic regions but appears to be rich in the number of species. The fauna displays a high degree of endemism with 91% of described species and 52% of the genera known only from Australia. Some genera appear to be ancient and probably represent a Pangean element in the Australian fauna. Others appear to have emerged in the late Jurassic when Africa was still joined to Gondwana, while some may have appeared in the Cretaceous or Palaeocene when Australia and South America were connected to Gondwana. More recent links with the Asian fauna are limited and there appears to be no widespread highly mobile global species other than the six introduced anthropophilic species. Maps of the worldwide distribution records extracted from the taxonomic literature are used to discuss the zoogeography of the subfamilies and tribes present in Australia. Molecular data using two mitochondrial genes (16S and COI) as well as a nuclear gene (28S) were compared with detailed morphological and morphometric analysis to examine populations initially determined as Heterolepisma sclerophylla or close to it. Distances of 0.9– 1.8% or greater in 28S, and 7.2–14% in COI were associated with morphologically distinct species. A southern Queensland population was found to be genetically, morphometrically and morphologically very distinct from those collected in NSW and was described as new (Heterolepisma sp. B). Six well-defined barcode clusters (“lineages”) were identified within the NSW populations, each with >4% divergence in COI sequences and each geographically restricted. Intracluster divergences are also large, and despite the well-supported phylogeny no clear “barcode gap” (distinction between intracluster and intercluster distances) was found for three of the six NSW populations. The 28S data distinguished only four of the six COI clusters from NSW with essentially no variation within each cluster. The 28S data generally aligned well with morphological evidence, clearly identifying Heterolepisma sp. B as a distinct species, and supporting also the description of Heterolepisma sp. A even though it only appears to differ from H. sclerophylla in the number of styli. Similar genetic distances are observed in 28S data for H. sclerophylla populations from North Nowra, Glenbrook/Burralow/Nattai and Megalong, however the Broulee and Wellington populations have identical 28S sequences. The low levels of variation in 28S sequences between NSW populations accord with the lack of unambiguous morphological differences.

Get the picture without a sermon : Enhancing a congreation's work and worship through (re)visioning the church - art relationship
- Authors: Rigby, John
- Date: 2014
- Type: Text , Thesis
- Full Text:
- Description: The church, throughout its history and motivated by the teachings of the Bible, has sought to assist people in finding meaning and direction in life. To this end it has used visual art to help people understand its message and increase people’s openness to the Bible’s redemptive story. After the Reformation, the emergent Protestant church had a more tenuous relationship with visual art, giving priority to oral forms of communication. Many small protestant congregations in current multi-faith Australia have little relationship with visual art and struggle to convey their message to the Australian society. A renewal of the church’s relationship with visual art is needed. This thesis including the exhibition employs a theology of creativity, hermeneutical skills and artistic reflection to illustrate how a (re)visioning of the church-art relationship can help the church in its work and worship.
