Survival, Injury, And Antibiotic Resistance Patterns Of Cronobacter Sakazakii And Escherichia Coli Resulting From Exposure To Low-Temperature Ground Water, Alisha L. Dailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bacteria are constantly being exposed to changing conditions in the environment. Exposure to adverse conditions such as pH, temperature, and desiccation may cause stress to the bacteria, potentially resulting in loss of viability and growth. Cronobacter sakazakii and Escherichia coli were exposed to cold temperature (4°C) and room temperature (24°C) nutrient-limiting groundwater. As a function of time (0 to 15 days), samples were removed from the stress and analyzed. Response of stressed cells was evaluated by three approaches: (i) traditional viable cell counts (nonselective and selective media), (ii) substrate utilization patterns (BIOLOG GN microplates), and (iii) antibiotic resistance patterns (modified …

Ion Transport Across Nano-Microchannel Interfaces., William Albert Booth

Graduate Theses, Dissertations, and Problem Reports (ETD)

Finite element numerical simulations are used to examine the effects of various parameters on synthetic charge-selective nanochannel systems in series with microchannels. In particular the origins of uidic ionic current rectification and the transient development of such systems in response to electric potential biases is explored. The origin of current rectification is these systems is found to be asymmetric concentration polarization. This leads to diffusion layers that form in response to an applied bias . The asymmetric diffusion layers may have 1D and higher dimensional origins. The systems are found to change over three time scales each associated with a …

Drawn From Artists’ Lives: An Empirical Study Of The Situation And Realisation Of Professional Visual Art Practices In The Western Australian Field Of Cultural Production, Duncan Robert Mckay

Theses: Doctorates and Masters

This thesis presents the findings of empirical research on the working lives of visual artists living and working in Western Australia. No detailed studies of this kind have previously been undertaken in a Western Australian context, though a series of national, economically framed studies have surveyed Australian artists working in a variety of art forms about their working lives on five occasions since the early 1980s. Collectively the reports published from these five studies make up the most comprehensive picture of artists’ economic activity that has been available to policymakers and others involved in arts and culture in this country …

Normal Mysticism : An Interdisciplinary Study Of Max Kudushin's Rabbinic Hermeneutic, Thomas L. Head

Theses: Doctorates and Masters

Max Kadushin (1895-1980) was a rabbi, professor, and preeminent figure in the history of American Conservative Jewish rabbinic thought. His hermeneutic system, which centers on the idea of organic religious value-concepts, has had a significant influence on the emerging Textual Reasoning movement.

In chapter one, I describe the intellectual climate in which Kadushin's system took shape—providing a short history of the 19th-century reform and haskalah movements, discussing the general outline of Alfred North Whitehead's process philosophy tradition, and placing new focus on the tension between Conservative Judaism and Mordecai Kaplan's emerging philosophy of Reconstructionism as a critical factor in the …

Inside Schizophrenia: Mending The Internal Conflict; And, The Historical, Cultural And Social Aspects Of Schizophrenia, Fiona Erica Nichols

Theses: Doctorates and Masters

This thesis comprises a memoir and essay on schizophrenia. It is estimated that 285,000 people suffer some form of schizophrenia in Australia. This means, on average, one in seventy people in Australia suffer from the disorder. For males, schizophrenia often develops in early adulthood. For females, it has later onset. There are about five types of schizophrenia: paranoid, catatonic, disorganised, undifferentiated, and residual. The focus of this thesis is on the diagnosis of Paranoid Schizophrenia. There is no cure, but it is treatable. However, people with a treatment resistant schizophrenia can find life difficult. The aim of the thesis is …

Transitioning Into Parenthood : Family Leisure And Heterosexual Couples In New Zealand, David Lamb

Theses: Doctorates and Masters

The key research question on which this study was based concerned the transition period from first time pregnancy through to first time parenthood for heterosexual couples in Christchurch, New Zealand. The particular focus on this study was on how this transition impacted upon access, opportunity and experiences of family leisure. As a result this study can claim to be longitudinal as it follows a number of couples from the stage of pregnancy into early parenthood. A number of subsidiary questions were developed to explore the different dimensions of the key research question in terms of: the impact of gender; the …

Characterising The Deformation Behaviour Of Human Tooth Enamel At The Microscale, Simona O'Brien

Theses: Doctorates and Masters

Enamel plays an important role in tooth function. Optimal combinations of composition and structure endow enamel with unique mechanical properties that remain largely unexplored. Specifically, more detailed understanding of the loadbearing ability of enamel is needed to mimic it synthetically and to design next generation biocomposite materials. This research investigates the variables that influence deformation behaviour of tooth enamel in relation to its hierarchical structure. Initially, a new method was developed for preparing flat, finely polished tooth samples that were maintained in their normal hydrated state for nanoindentation testing. In contrast to conventional methods, which commonly utilise either inappropriate or …

Lichens As A Biomonitoring Tool For Detecting Heavy Metal Air Pollution Associated With Industrial Activities In Collie, South-Western Australia, Meenu Chathurika Vitarana

Theses: Doctorates and Masters

During the last few decades, various techniques for using lichens as biomonitors have been developed for monitoring air pollution and forest ecosystem health. Lichens have been used effectively to determine the dispersion of heavy metals emitted by industrial point-sources; however the approach has not been commonly used in Australia. This thesis aimed to determine the effectiveness of using a lichen biomonitoring approach to measure the heavy metal pollutants emitted from coal-fired power stations and related industries in Collie, south-western Australia, an area with concern over poor air quality. Three different approaches to lichen biomonitoring were investigated. The first explored lichen …

On The Recognition Of Emotion From Physiological Data, Warren Creemers

Theses: Doctorates and Masters

This work encompasses several objectives, but is primarily concerned with an experiment where 33 participants were shown 32 slides in order to create ‗weakly induced emotions‘. Recordings of the participants‘ physiological state were taken as well as a self report of their emotional state. We then used an assortment of classifiers to predict emotional state from the recorded physiological signals, a process known as Physiological Pattern Recognition (PPR). We investigated techniques for recording, processing and extracting features from six different physiological signals: Electrocardiogram (ECG), Blood Volume Pulse (BVP), Galvanic Skin Response (GSR), Electromyography (EMG), for the corrugator muscle, skin temperature …

Mining Climate Data For Shire Level Wheat Yield Predictions In Western Australia, Yunous Vagh

Theses: Doctorates and Masters

Climate change and the reduction of available agricultural land are two of the most important factors that affect global food production especially in terms of wheat stores. An ever increasing world population places a huge demand on these resources. Consequently, there is a dire need to optimise food production.

Estimations of crop yield for the South West agricultural region of Western Australia have usually been based on statistical analyses by the Department of Agriculture and Food in Western Australia. Their estimations involve a system of crop planting recommendations and yield prediction tools based on crop variety trials. However, many crop …

A Study Of The Spatial Dynamics Of Some Introduced Avian Species In The Southwest Region Of Western Australia, Desiree L. Moon

Theses: Doctorates and Masters

The Southwest region of Western Australia is a recognised ‘biodiversity hotspot’, as it possesses high levels of biodiversity and endemism; it also holds a number of species threatened by habitat loss. The arrival of Europeans in the region wrought major changes on the natural landscape. Extensive tracts of bushland were cleared for housing, infrastructure, forestry, farming, and mining. Another challenge to regional biodiversity was the spread of exotic plants and animals (including birds); the latter provide the focus for the present study. The research examines four bird species that colonised the Southwest region following European settlement: Australian White Ibis (Threskiornis …

Metapopulation Theory Explains Black-Stripe Minnow (Pisces: Galaxiidae, Galaxiella Nigrostriata) Distribution In Seasonal Wetlands In South-West Western Australia, David M. Galeotti

Theses: Doctorates and Masters

The objective of this project was to determine if Galaxiella nigrostriata populations could belong to a metapopulation. Metapopulation theory describes how multiple populations with occasional connectivity are a ‘population of populations’. Some populations’ habitats have optimal conditions (source habitats), others experience regular extinctions (sink habitats). Connectivity allows repopulation of extinct or uninhabited habitats. Galaxiella nigrostriata occurred randomly in 11 seasonal wetlands in the Kemerton wetland complex in south-west Western Australia over a 16 year period. The wetlands did not appear to be connected.

Around 70% of wetlands on the Swan Coastal Plain in south-west WA have been filled or degraded …

Complexity And Creative Capacity : Reformulating The Problem Of Knowledge Transfer In Environmental Management, Kelly Chapman

Theses: Doctorates and Masters

The Ningaloo Reef is Australia’s largest fringing coral reef and an iconic tourist destination; however tourism development in Ningaloo has been ad hoc and the area is challenged by human pressure on numerous fronts. In response to these challenges a number of research agencies brought together a range of scientists to study the effects of human interaction on the reef. Moving from research to practice has been understood to depend on the adaptive capacity of the institutions responsible for governing human activities, in this case in the Ningaloo area. Knowledge transfer describes the suite of strategies used to try to …

Herbivory By Parma Mccullochi (Pomacentridae) : Its Role As An Ecosystem Engineer In Temperate Algal-Dominated Reefs, Frederico Vitelli

Theses: Doctorates and Masters

Pomacentridae is one of the most representative families of herbivorous fishes inhabiting both tropical and temperate reefs, yet the vast majority of studies examining feeding within this family have been undertaken in tropical rather than temperate regions. Despite the high abundances of the pomacentrid Parma mccullochi in temperate waters of Western Australia, and their likely importance in removing algae from reefs in the region, there is a lack of information on their diet and their impact on the reef algal community. This study aims to determine the role of Parma mccullochi as an ecosystem engineer on temperate algal-dominated reefs in …

Portraits Of Middle Eastern Gulf Female Students In Australian Universities, Susan Delahunty

Theses: Doctorates and Masters

This research explores the experiences and insights of ten Middle Eastern Gulf women as they cross international borders to study in Australian universities. The literature indicates that international students in Australia establish their identity within the context of their overseas existence. This is particularly important as Muslims may feel they are being placed in a precarious situation due to, more often than not, terrorism being linked to Islam. Also, when Muslim women wear Islamic or traditional attire, the general public tends to look upon them with curiosity. With this in mind, the complex and changed contexts faced by ten Middle …

Food Resource Availability For Carnaby's Cockatoo Calyptorhynchus Latirostris On The Swan Coast Plain, Teagan Johnston

Theses: Doctorates and Masters

To achieve a balance between sustainable development and conservation of threatened species, management depends on understanding the predicted response and interaction of that species with their environment in order to develop appropriate mitigating solutions. The Carnaby’s cockatoo Calyptorhynchus latirostris is declining across much of its range due to the detrimental effect of habitat degradation and loss. Since the decline of food resource availability in non-breeding areas is believed to be contributing to the reduction in the number of Carnaby’s cockatoos knowledge of the birds’ foraging ecology and the influence of external factors on food resource availability is essential for effective …

Understanding And Disrupting Institutional Settings : Using Networks Of Conversations To Re-Imagine Future Farming Lives, Robert Campbell

Theses: Doctorates and Masters

Farmers in Australia and elsewhere face the challenge of remaining profitable whilst dealing with adverse structural arrangements and public expectations to better manage environmental degradation. This thesis draws on arguments that dominant paradigms in agricultural science and environmental management have often been ineffective in addressing these apparently competing demands and appear poorly suited to ‘messy’ situations characterized by uncertainty and complexity, and in which diverse stakeholders are motivated by varying goals and values. Engaging with such situations requires a philosophy and methodology that accepts a multiplicity of perspectives and which seeks to learn about and reflect upon novel ways of …

The Relationship Between The Meaning Of Water And Sense Of Place : A Grounded Theory Study From Northern Thailand, Katesuda Sitthisuntikul

Theses: Doctorates and Masters

The literature suggests that a subtle relationship exists for communities between the meaning of water and sense of place, making fertile ground for systematic investigation. The relationship has obvious importance in today’s world, where people’s reliance on water, and the need for reliable supplies, form part of a common discourse in natural resource management. Yet, there has been much less discussion of what water means to people, how it connects with peoples’ sense of place, and what that might mean for the way people interact with their surroundings. The methodology of constructivist grounded theory was therefore appropriate to investigate this …

Experiences Of Adult Siblings Of Illicit Drug Users, Amy Mcalpine

Theses: Doctorates and Masters

The sibling relationship is unique in that it is relatively egalitarian, ascribed, and can be the longest-lasting across the lifespan. Siblings can act as supports for one another during major life events, both in childhood and adulthood. Siblings can also be a source of significant stress. The literature on family coping indicates that there are significant impacts to family members’ well-being from dealing with stress and strain that result from a family member’s drug use problem. However, researchers have not investigated the impacts on adult siblings despite the importance and uniqueness of sibling relationships. The broad aim of this research …

Verticordia Micropropagation Through Direct Ex Vitro Rooting, Belinda Delaney

Theses: Doctorates and Masters

The objective of this study was to improve the existing shoot multiplication protocol for Verticordia grandis (McComb, Arthur & Newll, 1986; Newell, Growns & McComb, 2005) and to investigate and establish reliable root induction and acclimatisation protocols to enhance survival of micropropagated plantlets. It was envisaged that these protocols would be successful in micropropagation, growth and survival of different V. grandis clones and possibly applicable to other Verticordia species.

The elongation of in vitro Verticordia shoots on multiplication media was improved by reducing the concentration of BAP from 1μM to 0.25 μM, which resulted in a more uniform shoot length …

Biomechanical Comparison Of Lower Limb Unloading Between Common Modalities Of Ankle Foot Orthoses, Andrea Blake Wanamaker

Electronic Theses and Dissertations

Tibial stress fractures and other lower extremity injuries can be treated using an ankle foot orthosis (AFO). AFOs are popular because they allow the patient to ambulate somewhat naturally while reducing weight bearing on the injured limb. Despite their popularity, it is currently unclear how well AFOs reduce lower extremity weight bearing.

The first objective of this investigation was to examine the ability of three commonly used ankle foot orthoses to reduce weight bearing within the lower limb by comparing the ground reaction force measured from a force platform to the force measured from an insole pressure measurement device inside …

Doing Impacting Being: A Case Study Of Service Learning As A Method Of Faith And Learning Integration, Calvin G. Roso

International Christian Community of Teacher Educators Journal

C. S. Lewis argues that Christians become more like Christ by practicing to be something they are not: “Pretense leads up to the real thing . . . very often the only way to get a quality in reality is to start behaving as if you had it already” (Lewis, 1952, p. 160). Likewise, educators indicate that when students practice and apply their learning “true understanding is demonstrated” (Tomlinson & McTighe, 2006, p. 67). Even Jesus, the Master Teacher, modeled experiential integration in training His disciples (Matthew 10:1-15; Luke 9:1-6; Mark 6:7-13). Doing impacts being—what we do and experience shapes …

Changes To Land Tenure And Pastoral Lease Ownership In Western Australia's Central Rangelands: Implications For Co-Operative, Landscape-Scale Management, Eddie J. Van Etten

Research outputs 2013

The majority of arid and semiarid land in the Western Australian pastoral zone has a long history of livestock grazing within an extensive network of predominantly family-held pastoral leases. A variety of different groups have purchased pastoral leases in the last five decades and, for many, making a profit from pastoralism is no longer a priority. For the central rangelands of Western Australia, these groups have included: government agencies, who have purchased some 9% of pastoral leases by area; private conservation organisations (<1% purchased); aboriginal communities and groups (∼7%); and mining companies (∼13%). The purchases of pastoral leases by government agencies was designed to improve the conservation status of arid-zone ecosystems, and is the first step in a process of changing land tenure to a conservation reserve. This paper summarises the extent and other characteristics of these changes in land tenure and ownership of pastoral leases, and explores the implications for land management and conservation, stemming from these changes. It demonstrates that large areas of contiguous land with no or reduced domestic stocking can now be found in many parts of these rangelands, particularly in the Coolgardie, Yalgoo and Pilbara bio-regions, with some leaseholders actively managing land for the conservation of biodiversity and restoring sites degraded through past over-grazing. In some bio-regions, such land covers considerable proportions of sub-catchments, suggesting that broad-scale conservation management and restoration objectives may be realised. It is argued that to fully realise these objectives requires effective communication and co-ordination between land managers, including sharing of ideas, view-points and resources. In particular, mining companies, now major holders of pastoral leases in Western Australia, can play an important role in contributing to and even facilitating such objectives.

Remarital Chances, Choices, And Economic Consequences: Issues Of Social And Personal Welfare, Kevin Shafer, Todd M. Jensen

Faculty Publications

Many divorced women experience a significant decline financial, social, physical and psychological well-being following a divorce. Using data from the NLSY79 (n = 2,520) we compare welfare recipients, mothers, and impoverished women to less marginalized divorcees on remarriage chances. Furthermore, we look at the kinds of men these women marry by focusing on the employment and education of new spouses. Finally, we address how remarriage and spousal quality (as defined by education and employment) impact economic well-being after divorce. Our results show that remarriage has positive economic effects, but that is dependent upon spousal quality. However, such matches are …

Perceived Food And Labor Equity And School Attendance Among Ugandan Children Living In Kin Care, Jini Roby, Stacey Shaw, Laurel George

Faculty Publications

Emerging research suggests that biological relatedness contributes to differential treatment between children being raised by kin and the biological children in the caregiver’s household. This potential concern may be elevated especially when household resources are stretched thin. In this study, 518 Ugandan youth and their caregivers were interviewed individually, examining the association between relatedness and perceived food and work equity, and school attendance. Household income, but not relatedness, was negatively associated with food inequity. However, relatedness was positively associated with perceived disparity in the distribution of work among children living in the household, and with children’s school attendance. These findings …
