Children's Exposure To Lead And Nickel In Esperance - A Case Study, Matthew Tristan Winters

Theses : Honours

This is a cross-sectional study of lead and nickel exposure of children aged 2-12 years living at varying distances from a point source of pollution in Esperance. Esperance was an ideal case study location because of previous environmental contamination with lead and nickel above background levels. Non-invasive biological samples of hair, toenails and urine were collected from participating children, and environmental samples, including house dust, soil and drinking water were also sampled from each participant household. Exposure was assessed by measuring the concentration of metals found in the biological samples, and determining their relationships with the environmental samples from each …

Anglo-Australians' Attitudes Towards Asylum Seekers And Egalitarianism, Antonietta Matrone Faulkner

Theses : Honours

Research has found that generally Australians hold negative attitudes towards asylum seekers. These negative attitudes appear to be influenced by perceptions of threat and false beliefs. The current study explored the attitudes of Anglo-Australians towards asylum seekers and how attitudes are related to the concept of Australian egalitarianism and fair go. Twelve semi-structured interviews were conducted for this study. Three main themes were identified through thematic content analysis: characterising asylum seekers, responses to asylum seekers in Australia, and constructing fairness.' Characterising asylum seekers represented the informants' constructs of asylum seekers as being genuine asylum seekers, or boat people …

E-Help: Community Perspectives On Help-Seeking Using Electronic Forms Of Communication, Jacqueline D. Myles-Pallister

Theses : Honours

The provision of mental health services using telephones, the Internet, and mobile phones (e-help), has been widely recommended as part of a solution to closing the gap between high prevalence of mental illness and low rates of service uptake. However, little is known about how potential users of these services view them. To address this gap, three focus groups (N = 17, age 17 - 69 years) were conducted to explore general community perspectives on using e-help. Interpretative phenomenological analysis identified three themes with related subthemes: (1) awareness; (2) trust and feeling safe when seeking and using e-help; (3) it …

Mcmansions: Re-Presenting A Divided, Subdivided And Uncanny Suburban Landscape, Mike Gray

Theses : Honours

This exegesis speculates on the rise and spread of 'McMansions' by exploring possible reactions to this architecture and the contextual dimensions of my photographic response. The exegesis aligns aspects of the 'Uncanny' (Freud, 1919) to new trends in domestic architecture and topographical photography. By pictorially offering a counter-narrative to more conventional representations of the 'dream home', it ironically demonstrates that some houses can be viewed as unhomely. The exegesis explains how cultural anxieties can be experienced when viewing contemporary trends in domestic architecture within new suburban developments. It does this by aligning the increased use of featurism (Boyd, 1980) in …

World War Ii Prisoner Of War Visual Art : Investigating Its Significance In Contemporary Society, Eileen Whitehead

Theses : Honours

This study examines closely some of the artworks produced by Howard Taylor, Ronald Searle and Ludwig Hirschfeld Mack while they were interned as prisoners of war (POWs) during World War II (WWII). It examines the significance of their POW and post-war artworks in the context of their experiences in WWII, the institutional representation of WWII POW art generally and, more broadly, the context in which wars shape the creative output of imprisoned soldiers and civilians. It further examines how POW artwork has influenced the choice of subject matter for some contemporary artists. I discuss a certain invisibility of POW artwork …

Editorial: Nutrition Research Reviews, Katherine Younger

Articles

The diverse nature of the reviews included in this issue of Nutrition Research Reviews highlights a problem that is becoming increasingly acute for journal editors, namely that of finding suitable reviewers (especially for the more esoteric manuscripts) who are prepared to devote some of their time and expertise to this crucial task. Peer-review underpins the whole ethos of scientific journal publishing as we currently know it. Without it, readers have little guarantee that the published material is credible, which in turn casts the authors in a dubious light, and with them the editors and publishers of the journals; the whole …

Developing Leadership In A Multitype Library Consortium: Ten Years Of Seflin Sun Seekers, Elizabeth A. Curry, Jeannette Smithee

Library Faculty Presentations & Publications

The Southeast Florida Library and Information Network (SEFLIN) has presented the Sun Seeker Leadership Institute biennially since 1997. SEFLIN, a multitype library consortium headquartered in Boca Raton, Florida, was one of the first groups to sponsor a library leadership institute held as a monthly series of events over the period of a year. One hundred library staff members from all types of libraries, large, small, public, and academic, have completed the leadership institute. After twelve years and six cohorts, SEFLIN is reviewing the project’s impact. This article outlines how and why the leadership institute was created, the program’s goals and …

Productivity-Diversity Relationships From Chemolithoautotrophically Based Sulfidic Karst Systems, Megan L. Porter, Annette Summers Engel, Thomas C. Kane, Brian K. Kinkle

International Journal of Speleology

Although ecosystems thriving in the absence of photosynthetic processes are no longer considered unique phenomena, we have yet to understand how these ecosystems are energetically sustained via chemosynthesis. Ecosystem energetics were measured in microbial mats from active sulfidic caves (Movile Cave, Romania; Frasassi Caves, Italy; Lower Kane Cave, Wyoming, USA; and Cesspool Cave, Virginia, USA) using radiotracer techniques. We also estimated bacterial diversity using 16S rRNA sequences to relate the productivity measurements to the composition of the microbial communities. All of the microbial communities investigated were dominated by chemolithoautotrophic productivity, with the highest rates from Movile Cave at 281 g …

Lights And Shadows On The Conservation Of A Rock Art Cave: The Case Of Lascaux Cave, Fabiola Bastian, Claude Alabouvette

International Journal of Speleology

Lascaux Cave was discovered in 1940. Twenty years after the first microbial contamination signs appeared. In the last forty years the cave suffered different fungal invasions. Here we discuss the past, present and future of the cave and the conservation of its rock art paintings to the light of data obtained using culture-dependent and –independent methods.

Protein Responsive Synthetic Materials For Biomedical Applications, Youyou Zheng

Doctoral Dissertations

"The production of synthetic materials with molecular recognition abilities towards biomacromolecules has been widely researched because of its potential applications in separations, sensing, therapeutics, etc. While molecular imprinting has become a commercially viable method for the production of synthetic materials with molecular recognition abilities towards small molecules, little success has been recorded towards protein targets. Proteins are difficult to imprint as they present a number of epitopes for imprinting, are difficult to remove from the completed material, and are incompatible with the densely crosslinked structures required. As a result, a novel surface molecular imprinting technique was developed to synthesize polymeric …

Rational Construction By Molecular Dynamics Modeling And Simulations Of Porous Adsorbent Media For Bioseparation, Enrico Riccardi

Doctoral Dissertations

"Ion-exchange chromatography employing porous adsorbent particles or monoliths in which charged ligands are immobilized onto polymeric extender molecules grafted on the pore surfaces of a base matrix has become a very important method for bioseparations. In this dissertation, a novel fundamental and systematic methodology has been developed that uses the molecular dynamics (MD) modeling and simulation approach to rationally design, construct, and characterize polymeric porous adsorbent media and study the transport and adsorption of a charged biomolecule (desmopressin) in a representative adsorbent medium. The MD results have also been utilized in a macroscopic model to study the large-scale dynamic behavior …

The Role Of Friction Stir Processing On The Microstructure And Mechanical Properties Of A Cast Aluminum Alloy, Saumyadeep Jana

Doctoral Dissertations

"Al-7Si-0.6Mg is one of the most important cast aluminum alloys because of its attractive mechanical properties and high castability. Microstructurally, the alloy consists of primary aluminum dendrites with eutectic Si particles in the interdendritic region. This makes the alloy quasi-brittle in nature which affects the ductility of the alloy to a great extent. In order to improve the ductility, the eutectic Si particles need to be refined which so far has been achieved by chemical and/or thermal modification. Friction stir processing (FSP) on the other hand can achieve the same through plastic deformation, and therefore replace the cast structure with …

Applications Of Sensor Arrays In Acoustic And Seismic Signal Processing, Peng Xie

Doctoral Dissertations

"This work investigates the applications of sensor arrays in the areas of acoustic and seismic signal processing. It comprises three papers.

The first paper explores the problem of blind source separation (BSS) for convolutive acoustic signals. It concentrates on the well known permutation and amplitude problems in frequency-domain BSS and proposes a new hybrid approach to solve them. This approach connects the separation processes across all frequency bins, and relies on a novel permutation control unit. This framework could greatly reduce computational load and improve separation performance. Synthesized and real-world experiments demonstrate its efficiency.

The second paper investigates a new …

Modeling And Analysis Of Noise Coupling In Multilayer Power/Ground Planes, Gang Feng

Doctoral Dissertations

"The simultaneous switching noise (SSN) in a multilayer power delivery network (PDN) is a critical problem in high-speed printed circuit board (PCB) designs. Full-wave methods are not computationally efficient for analyzing PCB structures normally with a multi-scale nature. In this thesis, a model for multilayer power/ground planes is proposed using basic plane pair blocks derived from the cavity model combined with the segmentation technique. Vias and other circuit elements can further be easily integrated in the multilayer plane model. As a result, the entire PDN model is much more computationally efficient than full-wave methods. Experimental and numerical results have validated …

Systematic Functional And Object-Oriented Product Design Frameworks, Jen-Chi Wu

Doctoral Dissertations

"The existing co-design methods of mechatronic products focus on co-design of mechanical and electronic components or co-design of computer hardware and software components. There exist no effective co-design methods for mechanical, electronic and software components at the concept design stage. The research objective of this dissertation work is to develop more effective systematic product design approaches for co-design of mechatronic products. Three innovative functional and object-oriented integrated design frameworks and one virtual prototyping application, which leverages on these three design frameworks, have been developed for co-design of mechatronic products. The three frameworks are: I) Hierarchical Object-Oriented Functional Modeling Framework, 2) …

Quality Of Service Provisioning Through Resource Allocation And Data Aggregation In Wireless Sensor Networks, Carl Larsen

Doctoral Dissertations

"In this dissertation, improvement of quality of service (QoS) provisioning in wireless sensor networks (WSN) is examined using four different methods. The first two focus on allocation of limited resources in the face of changing network and channel conditions, and thus improving performance in terms of throughput and delay. The second two methods focus on using data aggregation to minimize the size and number of packet transmissions reducing the energy consumption and improving network lifetime.

Therefore, in the first paper a novel adaptive and distributed fair scheduling (ADFS) protocol for WSN is presented that allocates the channel bandwidth in proportion …
