Electronic Theses and Dissertations Archive

This article explored the academic experiences of nontraditional students enrolled in an undergraduate degree program. For the purposes of this study students were deemed to be nontraditional if they met one of the following characteristics: had delayed enrollment into postsecondary education; attended college part-time; worked full time; were financially independent for financial aid purposes; had dependents other than a spouse; were a single parent; and/or were a GED recipient (NCES, n.d.). The researcher sought to justify the importance of gleaning additional information regarding different components of the learning processes and academic experiences in which nontraditional students were engaged in throughout …

I Am A Quiet Struggler: Conceptualizing The Identities Of Muslim American High School Students Within The Context Of Islamophobia., Wesam M. Salem

Electronic Theses and Dissertations Archive

The spread of Islamophobia in the U.S. positioned Muslims as different and inferior to American society and racialized their experiences by subjecting them to narratives of prejudices and stereotypes. This postcolonial interview study examined how Muslim American high school students conceptualized and negotiated their racialized identities within the context of Islamophobia and how the negotiation processes informed their learning in school, particularly the construction of their mathematics identity. The study built on postcolonial theorists, mathematics research, and decolonizing approaches to research to interrogate and (un)settle traditional and predetermined interviewing practices. Participants included six high school students (2 males and four …

Building Self-Efficacy And Persistence Through Stem E-Mentor Training: A Multi-Site Case Study, Kathryn Marie Sharpe

Electronic Theses and Dissertations Archive

The limited number of women persisting in STEM degree programs and pursuing STEM careers is concerning, particularly when one considers the absence of minority women in this field. One way of addressing this issue is to explore avenues that build womens STEM self-efficacy. Providing connections with other more experienced women involved in STEM through e-mentoring is one approach that could give women the support and experience they need to feel confident in their ability to succeed in STEM fields. Highly qualified mentors are a key component in the mentoring process and, therefore, need focused training that prepares them to support …

An Analysis Of Principals' Perceptions Of Their Levels Of Response To Instruction And Intervention, Kathryn King Redditt

Electronic Theses and Dissertations Archive

Recent resounding dialogue surrounding school improvement has led to reform initiatives including Response to Instruction and Intervention (RTI2). Although all 50 states have implemented some form of an RTI model, Tennessees state-wide framework to address struggling learners has placed us at the forefront of educational reform. The Response to Instruction and Intervention (RTI2) initiative in Tennessee was implemented as a framework for teaching and learning to ensure success for all learners through a model of high expectations and supports for students. The lack of research surrounding the perceptions of principals regarding RTI2 in their respective schools and districts has created …

Topological Properties Of The Standard Operations On Spaces Of Continuous Functions And Integrable Functions, Holly Michelle Renaud

Electronic Theses and Dissertations Archive

In this work, we consider different notions of openness for several operations on a large collection of different settings. We start with the scalar multiplication on sequence spaces, spaces of continuous functions, and integrable functions. We apply different techniques to derive weak-openness of multiplication on spaces of differentiable functions, endowed with a large collection of quasi-algebra norms. We consider the openness property of the dense-defined standard multiplication on spaces of integrable functions, as multiplication on these settings is only defined on a dense set. We adapt the definition of openness for the multiplication to include dense-defined products and then prove …

Dynamical Interference In The Vibronic Bond Breaking Reaction Of Hco, Shanyu Han, Xianfeng Zheng, Steve A. Ndengue, Yu Song, Richard Dawes, For Full List Of Authors, See Publisher's Website.

Chemistry Faculty Research & Creative Works

First-principles treatments of quantum molecular reaction dynamics have reached the level of quantitative accuracy even in cases with strong non-Born-Oppenheimer effects. This achievement permits the interpretation of puzzling experimental phenomena related to dynamics governed by multiple coupled potential energy surfaces. We present a combined experimental and theoretical study of the photodissociation of formyl radical (HCO). Oscillations observed in the distribution of product states are found to arise from the interference of matter waves-a manifestation analogous to Young's double-slit experiment.

Facial Re-Enactment, Speech Synthesis And The Rise Of The Deepfake, Nicholas Gardiner

Theses : Honours

Emergent technologies in the fields of audio speech synthesis and video facial manipulation have the potential to drastically impact our societal patterns of multimedia consumption. At a time when social media and internet culture is plagued by misinformation, propaganda and “fake news”, their latent misuse represents a possible looming threat to fragile systems of information sharing and social democratic discourse. It has thus become increasingly recognised in both academic and mainstream journalism that the ramifications of these tools must be examined to determine what they are and how their widespread availability can be managed.

This research project seeks to examine …

‘Bloodwood’ And ‘Liminal Spaces, Timeless Places: Abjection, Liminality And Landscape In Australian Gothic Fiction’, Karleah Olson

Theses : Honours

This creative honours project comprises a work of fiction titled ‘Bloodwood’ and an accompanying exegetical essay, exploring the concept of liminal space within the Australian landscape. It investigates the anxieties and consequences of past trauma that linger within the landscape of modern Australia, exploring themes such as time, connection to nature, trauma and grief. Using Julia Kristeva’s abjection theory, particularly her ideas on liminal space, this work addresses the contentious issue of postcolonial theory within the field of literary studies, as well as the concept of grief as a liminal process. These ideas are explored through the storylines of three …

Gamma Irradiation Response Of Photonic Crystal And Standard Optical Fibre Bragg Grating Sensors For Radiation Dosimetry, Desmond Baccini

Theses: Doctorates and Masters

This study investigates the use of Optical Fibre Bragg Grating Sensors (FBGs) for Gamma Radiation Dosimetry. A comparative analysis of responses to gamma irradiation between standard commercial FBGs and new generation FBGs written in Photonic Crystal fibre (PCF) were examined under similar regimes and conditions. Current research suggests that the FBGs performance, when exposed to Cobalt-60 gamma irradiation, can suffer cross sensitivity problems resulting from different external effects such as temperature. However, FBGs written in PCFs may be able to overcome these problems due to their design, flexibility of the shape, and size of the micro-holes in a PCF.

Ex-Post Service Contract Performance Management, Brian Forbes, Malcolm Brady

Articles

This paper highlights how contract incompleteness can threaten the performance of public procurement facilities management contracts during their implementation stages, based on a multiple case study comprising five public procurement services contracts. The paper takes a principle-agent view and with the unit of analysis being the contract itself. The paper shows that contract contingencies are almost inevitable and may stem from the written contract or from the participating organisations. Written and unwritten contract management mechanisms were used in practice to deal with contingencies as they arose in the services case studies examined. The paper found that written contracts do not …

Ionic Liquid Based Polymer Gel Electrolytes For Use With Germanium Thin Film Anodes In Lithium Ion Batteries, Louise M. Mcgrath, John Jones, Edwin Carey, James F. Rohan

Articles

Thermally stable, flexible polymer gel electrolytes with high ionic conductivity are prepared by mixing the ionic liquid 1‐butyl‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (C₄mpyrTFSI), LiTFSI and poly(vinylidene difluoride‐co‐hexafluoropropylene (PVDF‐HFP). FT‐IR and Raman spectroscopy show that an amorphous film is obtained for high (60 %) C₄mpyrTFSI contents. Thermogravimetric analysis (TGA) confirms that the polymer gels are stable below ∼300 °C in both nitrogen and air environments. Ionic conductivity of 1.9×10⁻³ S cm⁻² at room temperature is achieved for the 60 % ionic liquid loaded gel. Germanium (Ge) anodes maintain a coulombic efficiency above 95 % after 90 cycles in …

Fluorescence Quenching-Based Mechanism For Determination Of Hypochlorite By Coumarin-Derived Sensors, Karolina Starzak, Arkadiusz Matwijczuk, Bernadette Creaven, Alicja Matwijczuk, Sławomir Wybraniec, Dariusz Karcz

Articles

A fluorescence quenching-based mechanism for the determination of hypochlorite was proposed based on spectroscopic and chromatographic studies on the hypochlorite-sensing potency of three structurally similar and highly fluorescent coumarins. The mode of action was found to rely upon a chlorination of the coumarin-based probes resulting from their reaction with sodium hypochlorite. Importantly, the formation of chlorinated derivatives was accompanied by a linear decrease in the fluorescence intensities of the probes tested. The results obtained suggest the applicability of a coumarin-dependent hypochlorite recognition mechanism for the detection of, as well as for quantitative determination of, hypochlorite species in vitro.

Spheroid-3d And Monolayer-2d Intestinal Electrochemical Biosensor For Toxicity/Viability Testing: Applications In Drug Screening, Food Safety, And Environmental Pollutant Analysis, Evangelia Flampouri, Shahzad Imar, Kieran O'Connell, Baljit Singh

Articles

The rise of three-dimensional cell culture systems that provide in vivo-like environments for pharmaco-toxicological models has prompted the need for simple and robust viability assays suitable for complex cell architectural structures. This study addresses that challenge with the development of an in vitro enzyme based electrochemical sensor for viability/cytotoxicity assessment of two-dimensional (2D) monolayer and three-dimensional (3D) spheroid culture formats. The biosensor measures the cell viability/toxicity via electrochemical monitoring of the enzymatic activity of nonspecific esterases of viable cells, through the hydrolysis of 1-naphthyl acetate to 1-naphthol. The proposed sensor demonstrated strong correlation (r = 0.979) with viable …

Electrochemical Enzyme-Linked Immunosorbent Assay (E-Elisa) For Parasitic Nematode: Ostertagia Ostertagi (Brown Stomach Worm) Infections In Dairy Cattle, Baljit Singh, Evangelia Flampouri, Eithne Dempsey

Articles

A sensitive electrochemical immunoassay (e-ELISA) has been developed for the detection of the gastrointestinal parasitic nematode Ostertagia ostertagi (brown stomach worm) in infected and control serum samples. An antigen-indirect immunoassay format was employed to detect the presence of O. ostertagi antibodies, coupled with an anti-species monoclonal horseradish peroxidase (HRP) conjugate. ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)) and TMB (3,3',5,5'-tetramethylbenzidine/hydrogen peroxide) were investigated as both chromogenic visualising reagents for optical ELISA and electroactive substrates for electrochemical ELISA in the HRP catalysed oxidation reaction. Coulometry was applied for the detection of O. ostertagi antibodies (via TMB electrochemistry) and compared with the commercial optical ELISA (ABTS …

Modeling Organic Carbon Accumulation Rates And Residence Times In Coastal Vegetated Ecosystems, E. Fay Belshe, Jose Sanjuan, Carmen Leiva-Dueñas, Nerea Piñeiro-Juncal, Oscar Serrano, Paul Lavery, Miguel Angel Mateo

Research outputs 2014 to 2021

Coastal vegetated “blue carbon” ecosystems can store large quantities of organic carbon (OC) within their soils; however, the importance of these sinks for climate change mitigation depends on the OC accumulation rate (CAR) and residence time. Here we evaluate how two modeling approaches, a Bayesian age-depth model alone or in combination with a two-pool OC model, aid in our understanding of the time lines of OC within seagrass soils. Fitting these models to data from Posidonia oceanica soil cores, we show that age-depth models provided reasonable CAR estimates but resulted in a 22% higher estimation of OC burial rates when …

Contractual Tax Reform, Michael B. Abramowicz, Andrew `Blair-Stanek

GW Law Faculty Publications & Other Works

One-size-fits-all taxation fails to accommodate diverse taxpayer circumstances. This Article proposes allowing taxpayers to contract into alternative tax regimes administered by private intermediaries. Participating taxpayers would make payments to the intermediaries pursuant to contract, and the intermediaries would be required to pay to the government at least as much as these taxpayers would have paid the government otherwise. That amount is determined based on the actual tax receipts of a control group, taxpayers who wish to contract with an intermediary but instead are chosen at random to continue under the status quo. These alternative tax regimes might better accommodate taxpayers’ …

The Very Brief History Of Decentralized Blockchain Governance, Michael B. Abramowicz

GW Law Faculty Publications & Other Works

An emergent form of blockchain governance involves the use of formal games that give participants incentives to identify focal resolutions to normative questions. This symposium contribution provides a brief survey of the literature proposing and critiquing the use of such mechanisms, and it evaluates early laboratory and real-world experiments with this approach to decentralized decisionmaking.
