The Effect Of Marine Snow Particle Distribution On The Foraging Behavior Of Calanus Pacificus, Elena Beckhaus

Theses

Marine snow is a major component of the biological pump, through which carbon is exported to the deep ocean. The sinking of marine snow can be disrupted by organisms, including many species of zooplankton that ingest or break up aggregates. These processes can have important impacts on planktonic food web dynamics and carbon export. Marine snow can have vertically patchy distributions, occurring in thin layers, which may further affect interactions with zooplankton. In this lab-based study, we examined how the presence of a marine snow layer affects copepod behavior and ingestion.

We conducted a series of experiments in which copepods …

Design And Implementation Of Photovoltaic Energy Harvesting Automaton, Iskandar Askarov

Theses

Global domestic electricity consumption has been rapidly increasing in the past three decades. In fact, from 1990 to 2020, consumption has more than doubled from 10,120 TWh to 23,177 TWh [1]. Moreover, consumers have been turning more towards clean, renewable energy sources such as Photovoltaic. According to International Energy Agency, global Solar power generation alone in 2019 has reached almost 3% [4] of the electricity supply. Even though the efficiency of photovoltaic panels has been growing, presently, the highest efficiency solar panels available to an average consumer range only from 20%-22% [14]. Many research papers have been published to increase …

Optimising The Carcass Merit Of Irish Beef Cattle Using Genetic And Non-Genetic Information At The Animal And Herd Level, David Kenny

Theses

Failure of beef carcasses to achieve desirable carcass specifications represent inefficiencies within the supply chain, namely greater carcass processing costs and the inability of the resulting primal cuts to conform to high-value market specifications. Analysis of a representative sample of prime Irish beef cattle conducted in this thesis determined that 59% of cattle fail to achieve the desired carcass specifications of the supply chain at slaughter. The objective of this thesis was to use readily available information to define strategies that could help to reduce this statistic. Firstly, the likelihood of Irish beef carcasses achieving the desired carcass specifications was …

Beyond The Supernova : Time, Space, And Utopia In Outer Wilds, Sarah Salajka

Theses

Video games have evolved from simplistic marks moving on a screen to a diverse and inventive storytelling medium unique from other narrative forms. They allow for new methods of approaching traditional literary forms, such as the utopia. The utopian genre has seen a series of formal changes as social and historical contexts changed over time. This thesis proposes a new approach to the utopian genre borne from the current inability to imagine a future. While previous literary versions of utopia were expressed by moving forward through time or displacement through space, current social and environmental circumstances render this impossible, and …

Characterization Of Trat Protein Encoded In Incf Resistance Plasmids, Katelyn Ashley Lott

Theses

Drug-resistant infections pose serious medical threats, and causative resistance genes spread through plasmid conjugation. The TraT protein is a virulence factor encoded in drug-resistance F-plasmids. TraT itself provides protection from conjugation, serum complement, and bacteriophages, but the protective mechanism is unknown. To facilitate mechanism studies, I developed improved purification protocols for isolation of the soluble domain of F-plasmid TraT from Escherichia coli. Wild-type TraT and two variants were obtained. TraT domain forms several types of oligomers in vitro, also observed in full-length TraT. This oligomerization is stable without membrane attachment and in broad range of salt concentrations. Purified …

Federal Fashion: Uniform Modification, Self-Expression, And The Union Infantry Officer Of The American Civil War, Clayton Davis

Theses

The military uniforms of the American Civil War, particularly on the Union side, varied tremendously through time and location. There were an endless number of combinations􀂲myriad boots and hats, coats and jackets, insignias, and trousers. That was true for officers, especially commissioned officers, who exercised the greatest aesthetic freedom. Scattered works have broached the topic of officer uniforms, especially those of Confederate officers, though their Union counterparts have gone under the microscope also. Invariably, these works include non-regulation uniforms, either compiled by officers from separate pieces or handmade by one of the hundreds of tailors working across the nation. However, …

The Fountain Formula. Damien Hirst’S Use Of Marcel Duchamp’S Readymade Controversy, Grayson Nader

Theses

Controversial art challenges the norms of society, by pushing boundaries to expose what is comfortable and uncomfortable. It inevitably garners attention and demands discourse. Marcel Duchamp was an innovator of controversy. He was angered by the status quo and material greed of the art industry of the early 1900s and rebelled against it with his now-famous readymade, Fountain. In Fountain, Duchamp created a formula that used controversy to garner attention from the public, the media and the art world. This formula was used by various artists throughout the past century. Contemporary artist Damien Hirst was disillusioned by the monotony of …

Perspectives Of Reading For Pleasure Pedagogy In Western Australian School Classrooms, Jessica Nailer

Theses

Australian children read for pleasure less and less as they move through primary school, with a noticeable decline emerging in the middle primary school years. Reading for Pleasure at School (RfPS) also appears to have become de-prioritised in primary schools, with greater emphasis in the broader literacy education dialogue placed on instructional reading pedagogy and standardised literacy testing. This research focused on the pedagogy that meaningfully supports RfPS in Years 3-6, within a framework of school culture, teacher practices and the physical environment. This investigation aimed to explore the perspectives of three key stakeholder groups from one Western Australian independent …

'Ice In The Family' : Exploring The Experiences Of Close Family Members When Another Family Member Is Using Methamphetamine, Douglas Greg Gordon

Theses

Worldwide, the impact of illicit methamphetamine use has been increasingly recognised over the past two decades. Emergency Department presentations and physical and mental health effects have led to a focus on developing effective treatments for methamphetamine users. Little research has explored the impact, specifically of methamphetamine, on family members. Methamphetamine itself possesses unique differences from other drugs in both its direct effects and its mental and physical health impact on the user.

To this end, this longitudinal qualitative study used interpretative phenomenological analysis to understand the lived experiences of family members of methamphetamine users. The study was conducted in Bunbury …

'Are We Doing The Right Thing?' Utilising Security Governance To Reform The Us Drone Program, Jane Minson

Theses

The use of unmanned aerial vehicles, or drones, for counterterrorism purposes by the United States within its targeted killing program has been deeply controversial. Used in each presidential administration since the terrorist attacks of September 11, 2001, drones have sparked debate, in part due to their contribution to civilian deaths; their killing of high-value terrorist targets including, on at least one occasion, a US citizen; and the heightened secrecy that has surrounded the program with little formal oversight and, as such, little accountability. This thesis uses this contextual framework – with a particular focus on the administration of President Barack …

In 2000, the United Nations (UN) developed the Millennium Development Goals (MDGs) as an international framework to address poverty, promote sustainable development, and improve global health. The framework was translated into 8 goals with goals 4 and 5 targeting the reduction of child mortality and the improvement of maternal health. The UN and the World Health Organization (WHO) encouraged nurses and midwives to participate in the implementation process of the MDGs, and each country had the responsibility of formulating its own implementation policies and plans. The encouragement to participate was from the understanding that nurses and midwives are the backbone …

Assess, Address, Progress: An Online Approach To Evaluate And Develop Teacher Education Students’ Numeracy Capability, Kate Hartup

Theses

For as long as numeracy has been assessed as a major domain in Australia (since 2003), Australian school students’ numeracy levels have been declining (Thomson et al., 2019). This decline is evident despite it being a national requirement for teachers to teach numeracy skills across all subject areas at all year levels (Australian Curriculum and Reporting Authority (ACARA), n.d.). Although there are several definitions of numeracy, fundamentally it is the application of mathematics and the ability to interpret and utilise mathematical information (Australian Council for Educational Research (ACER), 2017). Given that teachers’ mathematical knowledge has been shown to affect their …

Developing Mathematical Identities: Australian Children’S Gendered Constructs In The First Formal Year Of School, Rachelle Glynn

Theses

Researchers have been intrigued by the dichotomy of similar achievement levels between boys and girls but disparate mathematical attitudes, which show that girls are much less likely to enjoy or engage with mathematics or choose professions involving mathematics (Kyriacou & Goulding, 2006; Vale, 2008). Although studies have explored differences in boys' and girls' perceptions of their mathematical identity from age seven, there has not been research conducted on students as they begin school to see what gendered perceptions they bring to their mathematical learning. This study seeks to answer the question: How are girls’ and boys’ mathematical identities being informed …

Reinterpreting The Villain: Changing The Pattern Of The Fairy Tale Through Sleeping Beauty’S Maleficent, Mackenzie Waldon

Theses

Recent filmic representations of the fairy tale villain can offer powerful counter-narratives to archetypal fairy tale stories. This thesis examines how certain contemporary representations of fairy tales have reinterpreted the traditional ‘villain’ archetype, revealing a greater diversity of perspectives. Using John Stephens’ and Peter Stockwell’s cognitive poetics theory on schema and scripts as a theoretical framework, this thesis closely analyses the known Disney fairy tale villain, Sleeping Beauty’s (1959) Maleficent, as she is portrayed in the live-action films Maleficent (2014) and Maleficent: Mistress of Evil (2019), as well as Disney’s Descendants (2015, 2017, 2019) films. By analysing the patterns and …

Transgression And Its Practice: The Role Of The Cultural Provocateur From The Twentieth To The Twenty-First Century, Luke Beattie

Theses

This thesis addresses the axiom that cultural provocation has lost its potential as a strategy of subversion due to the capacity of late capitalism – aka neoliberalism – to imbue any venture with profit-generating potential. In light of the tensions between economic exploitation in a digital consumer society and the transformative potential of subversive and transgressive art and performances, this thesis produces a “cognitive map” that reflects the current state of cultural provocation in the absence of an understandable social totality, reflective of the decentering affect and effects that constitutes late capitalism. In generating this cognitive map, the thesis examines …
