A Critical Control Approach To Preventing Fatalities In Construction, Roberta J. Selleck

Theses: Doctorates and Masters

Workplace fatalities continue to occur within the Australian construction industry at an unacceptably high rate. Most fatalities can be attributed to worker exposure to fatal energies while conducting high risk tasks in a dynamic work environment. Construction fatalities are usually single fatality events related to occupational safety hazards which are either not recognised by workers or not consistently controlled through existing safety practices. By comparison other resources industries have lower fatality rates because of their focus on identifying the controls and verification activities needed to address Major Accident Events (MAEs) and Principal Hazards in a manner that prevents fatalities.

Island Meltdown: Demise Of The Abrolhos Painted Button-Quail Turnix Varius Scintillans In The Face Of Multiple Threats, Ryan Carter

Theses: Doctorates and Masters

Island avifauna suffer high rates of extinction and decline. The major threats to island birds centre around the ecological impacts of invasive predators, competitors, and grazers. The Abrolhos Painted Button-quail (Turnix varius scintillans) is a subspecies that has been determined to be the 5th most likely taxon to become extinct in Australia. T. v. scintillans historically inhabited three islands in the Houtman Abrolhos archipelago off the mid-west coast of Australia. This study aimed to 1) confirm the status of T. v. scintillans on North Island and determine the main causes of decline, 2) model habitat variables with detections from camera …

Plant-Herbivore Interactions In A Changing Climate And Implications For Seagrass Resilience, Caitlyn M. O'Dea

Theses: Doctorates and Masters

Climate change is affecting herbivore distributions and abundance, resulting in intensified grazing pressure on foundation species such as seagrasses. This, coupled with other, rapid changes in estuarine ecosystems, may threaten the resilience of seagrass. While the overall resilience of seagrasses is generally well-studied, the timeframes of recovery have received comparatively little attention, particularly in temperate estuaries. This study investigated the recovery time of two colonising seagrasses (Halophila ovalis and Ruppia megacarpa) following various intensities of simulated grazing in two southwestern Australian estuaries. Simulated grazing treatments (25%, 50%, 75%, and 100% removal from 1 m2 plots) were applied in field experiments …

Performance And Interpretation: Beethoven's Opus 110, Izaac J. Masters

Theses: Doctorates and Masters

Within the context of professional music making, an increasing number of pianists use both modern and historical pianos as a matter of course. Yet, not infrequently, it seems that there is little awareness of how the inherent acoustic characteristics of each instrument may be used to inform interpretation, and the instrument-specific pianistic techniques that are needed if interpretation is to be optimised. This study explores issues of interpretation and performance as applied to Beethoven’s Piano Sonata in Ab major, op. 110. Three different performative interpretations of the sonata are constructed, each relating to a specific grand piano––made by, respectively, Conrad …

Quantifying And Managing The Impact Of Electric Vehicles On Power Distribution Assets, Pravakar Pradhan

Theses: Doctorates and Masters

Concern over the transportation sector’s greenhouse gas (GHG) emissions, which make up around 23% of all energy-related CO2 emissions, has grown in recent years. The widespread use of electric vehicles will be the primary strategy for tackling this issue. About 30% of the world’s passenger vehicle fleet is anticipated to be electrified by the year 2040. Moreover, the existing power distribution assets are already operating near their nominal capacities, and most of them have been in service for more than 25 years. Replacement of these assets will be very costly and disruptive to the power distribution network. Ergo, the main …

The Influence Of Networks On Suppliers’ Sustainable Innovation In Public Procurement: Insights From Ghana’S Public Works Sector, Peter Adjei-Bamfo

Theses: Doctorates and Masters

In recent times, governments have been using their procurement function to drive innovation in firms’ product outcomes and to improve operational activities that pose sustainability challenges. Ghana, for example, is currently advancing and upgrading its public works infrastructure with revenues from its commercialised oil reserves to match and improve its anticipated middle-income economy status. Faced with several sustainability challenges, such as environmental pollution and resource depletion, desecration of cultural heritage sites and exposure of labour force to poor working conditions, public works infrastructure procurements constitute a larger proportion of government procurement expenditure, globally, compared with the procurement of goods and …

The Cartographies Of Place: Approaches To Audio-Visual Composition Incorporating Aspects Of Place, Wing S. Tsang

Theses: Doctorates and Masters

Incorporating aural and visual elements of a place in a composition serves as a powerful way of exploring the intersection of time, history and geography associated with a location. The combination of these elements acts as an invitation for deeper engagement by offering multiple perspectives of place. One way of exploring these intersections is through incorporating aspects of place—in the form of field recordings, field footage and cartographical information—into audio and audio-visual work, where spatial and physical information can be situated as a way of representing an individual’s surroundings and subjective realities of place. This practice-led exegesis aims to explore …

School of Engineering, Computing and Mathematics

The global energy crisis and rising climate concerns are encouraging the transition to a more sustainable economy. Monitoring energy prices has become increasingly important for analysts, policymakers and businesses to tackle the current situation by increasing the integration of renewable energy sources, strengthening the resilience of the energy system to price shocks and reducing its dependence on fossil fuel imports, as well as improving the affordability of energy for consumers. We set up a copula-based ARJI-GARCH model to investigate the timevarying and non-linear dependence between renewable and non-renewable asset prices in the European energy market. Our results show that the …

Comparison Of Toxicity Of Silver Nanomaterials And Silver Nitrate On Developing Zebrafish Embryos: Bioavailability, Osmoregulatory And Oxidative Stress, Spp Pereira, D Boyle, Aja Nogueira, Rd Handy

School of Biological and Marine Sciences

The mechanisms of toxicity of engineered nanomaterials (ENMs) to the early life stages of freshwater fish, and the relative hazard compared to dissolved metals, is only partially understood. In the present study, zebrafish (Danio rerio) embryos were exposed to lethal concentrations of silver nitrate (AgNO3) or silver (Ag) ENMs (primary size 42.5 ± 10.2 nm). The 96 h-LC50 for AgNO3 was 32.8 ± 0.72 μg Ag L-1 (mean ± 95% CI) compared to 6.5 ± 0.4 mg L-1 of the whole material for Ag ENMs; with the ENMs being orders of magnitude less toxic than the metal salt. The EC50 …

Effects Of Preservation By Ethanol On Δ13c And Δ15n Of Three Tissues Of The Critically Endangered European Eel Anguilla Anguilla, Rose M. Boardman, Adrian C. Pinder, Adam T. Piper, Catherine Gutmann Roberts, Rosalind M. Wright, John Robert Britton

School of Biological and Marine Sciences

The temporal effects of ethanol preservation on the δ13C and δ15N values of tissues excised from European eel Anguilla anguilla were assessed. Preservation significantly enriched 13C values of fin and mucus but not dorsal muscle. The 13C enrichment occurred in the initial 15 days of preservation and was independent of initial eel mass. Tissue preservation effects on δ15N values were negligible. These tissue-specific isotopic shifts should be considered when ethanol-preserved eel samples are used.

Medical Diagnostic Value Of Digital Pcr (Dpcr): A Systematic Review, Sophia Nazir

School of Engineering, Computing and Mathematics

Digital polymerase chain reaction (dPCR) is an emerging technique for the absolute quantification of target nucleic acids. dPCR got attention as a precise quantification tool in preclinical research, particularly when used to detect genetic mutations and result in highly precise measurements. In dPCR, the statistic of Poisson distribution was followed for the random distribution of molecules in different partitions, which is essential for dPCR quantification. Amplified target sequences in different partitions are identified by fluorescence and each partition functions as a separate PCR microreactor. Without the need for calibration, the percentage of PCR-positive partitions is sufficient to estimate the concentration …

Mouthwashes: Alternatives And Future Directions, Brett Duane, Tami Yap, Prasanna Neelakantan, Robert Anthonappa, Raul Bescos, Colman Mcgrath, Michael Mccullough, Zoë Brookes

Peninsula Dental School

This narrative review summarises “alternative” or “natural” over-the-counter (OTC) mouthwashes not covered elsewhere in this supplement and newly emerging products, as potential mouthwashes of the future. The “natural” mouthwashes reviewed include saltwater, baking soda, coconut oil, charcoal, propolis, seaweeds, and probiotics. Other than essential oils, it is apparent that their clinical effectiveness is still under debate, but there is some evidence to suggest that propolis reduces plaque and gingivitis. This review also covers the host immune response, via novel anti-inmmunomodulant mouthwashes, such as erythropoietin to reduce inflammation with oral mucositis (OM) after radiotherapy. The emerging concept of nanoparticle-containing mouthwashes, such …

Accumulation Of Polystyrene Nanoplastics And Triclosan By A Model Tooth-Carp Fish, Aphaniops Hormuzensis (Teleostei: Aphaniidae), Maryam Saemi-Komsari, Reza Pashaei, Sajjad Abbasi, Hamid Reza Esmaeili, Reda Dzingelevičienė, Hadavand B Shirkavand, Kalako M Pasalari, Malgorzata Szultka-Mlynska, Renata Gadzała-Kopciuch, Boguslaw Buszewski, Andrew Turner

School of Geography, Earth and Environmental Sciences

The presence and effects of nanoplastics (NPs; <1 μm) in the aquatic environment are a growing concern. In this study, a model tooth-carp fish, Aphaniops hormuzensis, has been exposed to different concentrations of fluorescent polystyrene nanoplastics (PS-NP) in its diet (up to 5 mg kg−1) over periods of 28 d and the particle accumulation in different tissues determined. Accumulation was observed in both digestive and non-digestive organs, with concentrations greater in the gut, liver and gill (up to 400 μg kg−1 dw) than in the skin and muscle (<180 μg kg−1 dw), but no dependency on exposure time or dose was evident. The presence of the organic contaminant, triclosan (TCS), in the diet and at concentrations up to 0.5 μg kg−1 did not affect PS-NP uptake by A. hormuzensis, while TCS accumulation in the whole body increased with time (up to 10 μg kg−1) and, likewise, appeared to be unaffected by the presence of PS-NPs. These observations suggest that the two contaminants do not interact with each other or that any interactions have no impact on accumulation. The results of this study add to the growing body of evidence that NPs can be translocated by aquatic organisms after ingestion, and reveal that, for the species and conditions employed, nanoplastics are accumulated more readily than a widely used organic chemical.

Turning Sanctions Into Reparations: Lessons For Russia/Ukraine, Evan J. Criddle

Faculty Publications

Within the past year, members of Congress have introduced nearly a dozen bills to make Russia pay for its military aggression against Ukraine. This Essay argues that none of the bills are satisfactory because they would either violate international law or fail to deliver meaningful compensation to Ukraine. Instead, the Essay urges policymakers to use economic sanctions as leverage to compel Russia to make reparations through an international claims-settlement process.

A Prophylactic Approach To Compact Constitutionality, Katherine Mims Crocker

Faculty Publications

From COVID-19 to climate change, immigration to health insurance, firearms control to electoral reform: state politicians have sought to address all these hot-button issues by joining forces with other states. The U.S. Constitution, however, forbids states to “enter into any Agreement or Compact” with each other “without the Consent of Congress,” a requirement that proponents of much interstate action, especially around controversial topics, would hope to circumvent.

The Supreme Court lets them do just that. By interpreting “any Agreement or Compact” so narrowly that it is difficult to see what besides otherwise unlawful coordination qualifies, the Court has essentially read …

Comparing & Contrasting Economic And Natural Law Approaches To Policymaking, Eric Kades

Faculty Publications

Eric Claeys’s monograph, Natural Property Rights, offers a comprehensive and thoughtful articulation of a general theory of property rights rooted in the natural law tradition. This detailed review compares Claeys’s work with the consequentialist law and economics perspective on property. After contrasting their objectives, assumptions, and methodologies this article concludes that, unlike more absolutist approaches, Claeys’s flavor of natural property rights places a modicum of weight on the welfare effects central to economic analysis. This restrained nod in the direction of practicality, however, does not eliminate some of the long-known weaknesses of natural law. Perhaps the most glaring gap …

Technology Integration In Higher Education And Student Privacy Beyond Learning Environments -- A Comparison Of The Uk And Us Perspective, Iria Giuffrida, Alex Hall

Faculty Publications

Technology integration in higher education (HE) has brought immense innovation. While research is investigating the benefits of leveraging, through learning analytics, the data created by the greater presence of technology in HE, it is also analysing the privacy implications of vast universes of data now at the fingertips of HE administrators. This paper argues that student privacy challenges linked to technology integration occur not only within but also beyond learning environments, namely at the enterprise level. By analysing the UK and US legal frameworks surrounding how HE institutions respond to parents demanding disclosure of their adult children's personal data in …

Subordination Through Schedules, Nicole Buonocore Porter

Faculty Publications

Our jobs are not only about the work we do—they are also about when and where we do that work. For a variety of reasons, employees with disabilities often seek modifications of their employers’ policies regarding when and where work is performed. These accommodations are often necessary for the employee to remain employed. The Americans with Disabilities Act (“ADA”) requires employers to provide reasonable accommodations to employees with disabilities, and these accommodations can include schedule changes. But research demonstrates that when responding to accommodation requests under the ADA, employers are often reluctant to grant requests to modify the rules regarding …
