Investigation Of Histomoniasis Prevention In Poultry, Lesleigh Beer

Graduate Theses and Dissertations

Histomonas meleagridis is the etiological agent of histomoniasis, also commonly known as blackhead disease. This protozoal disease of poultry is detrimental to turkeys with flock mortalities often reaching 80-100%, although other gallinaceous birds are susceptible. Since the voluntary removal of nitarsone in 2015, the poultry industry is suffering with no approved prophylactics, therapeutics, or vaccines for this disease. The objectives of this dissertation were to evaluate multiple methods for prevention or control of histomoniasis, including dietary chemoprophylaxis and vaccination. Specifically, this research evaluated quinine as a chemoprophylactic candidate (Chapter 3) or live-attenuated H. meleagridis as vaccine candidates (Chapter 4) in …

Lgbtq+ College Students' Perceptions Of Social Presence And Self-Disclosure In Online Learning: A Single-Case Study, Scott Anthony Wright

Graduate Theses and Dissertations

Social interaction among learners plays a significant role in online learning environments (Garrison, 2006; Kreijns et al., 2014; Mykota, 2017). The construct of social presence in online courses is important because it influences interaction and connectedness among learners and its effects on their learning outcomes and emotional well-being. Social presence at its essence refers to how an individual is perceived as a "real person" in an online environment (Gunawardena & Zittle, 1997). Online students must decide what aspects of their social identities they share in their interactions with their peers and instructors. Furthermore, LGBTQ+ students must negotiate what aspects of …

Graduate Theses and Dissertations

The flooring in a food processing environment can become contaminated with pathogenic bacteria in many ways including foot and equipment traffic, incoming materials, and drain backups. Turmeric (Curcuma longa L.) rhizome powder and seventeen other commercially available powdered floor treatments with a variety of active ingredients including quaternary ammonium compounds (QAC), sodium percarbonate and similar perhydrates (SPC), urea, and borax, were investigated for reducing the levels of pathogens on flooring thereby reducing the risk of cross-contamination from the floor to food contact surfaces. Some of the commercially available floor treatments were Environmental Protection Agency (EPA) registered antimicrobials while others were …

The Morphodynamic Interaction Of River Deltas And Their Marshes, Kelly M. Sanks

Graduate Theses and Dissertations

Globally, many of the largest river deltas contain vast marsh platforms that are currently threatened due to a combination of anthropogenic alterations to rivers and increasing relative sea level rise. Restoration and management plans for river deltas depend on optimizing riverine sediment accumulation in marsh platforms. However, the accumulation of organic material in marsh platforms is often neglected in predictive models and the interaction of ecogeomorphic processes governing marsh accumulation with the physical processes governing river delta growth is poorly understood.

Herein, I investigate this complex relationship through a combination of field and experimental studies. I show that in coastal …

Adapting Animals: Nineteenth-Century British Literature, Science, And Media, Kristen Layne Figgins

Graduate Theses and Dissertations

In the nineteenth century, Charles Darwin and other proponents of evolutionary theory provided a theoretical framework for discussing the question of humanity’s place in the world. These nascent theories emphasized the shared animal nature of humans and the nonhuman creatures who had once occupied a distinctly lower place on the chain of being. My dissertation addresses the question of how nineteenth-century scientific attitudes about animals were reflected in the literature of the period. By examining culture-texts from the nineteenth century, it is clear that literature was an active participant in extending scientific knowledge, often by playing with the blending categorical …

Criticizing Judges: A Lawyer's Professional Responsibility, Lonnie T. Brown

Georgia Law Review

Lawyers, as officers of the court, are expected to act with deference and respect toward judges. Speaking sharply to or publicly criticizing members of the bench is frowned upon and not infrequently met with punitive responses. The judiciary, however, is not above reproach. Judges are fallible and may possess personal biases, tainting self-interest, or even prejudice. As such, at times, they must disqualify themselves if their ability to dispense justice fairly and impartially can reasonably be questioned. Indeed, the very nature of a judge’s role requires avoidance of even the “appearance of impropriety.” When judges fail to adhere to this …

Deadly 'Toxins': A National Empirical Study Of Racial Bias And Future Dangerousness Determinations, Justin D. Levinson, G. Ben Cohen, Koichi Hioki

Georgia Law Review

Since the beginning of the modern Death Penalty Era, one of the most important—and fraught—areas of capital punishment has been the so-called “future dangerousness” determination, a threshold inquiry that literally rests the defendant’s life or death on jurors’ predictions of the future. An overwhelming majority of capital executions have occurred in jurisdictions that embrace the perceived legitimacy of the future dangerousness inquiry, despite its obvious flaws and potential connection to the age-old racial disparities that continue to plague capital punishment. This Article presents, and empirically tests, the hypothesis that jurors’ future dangerousness assessments cannot be separated from their racial and …

Agents Of Bioshield: The Fda, Emergency Use Authorizations, And Public Trust, Kirstiana Perryman

Georgia Law Review

The SARS-CoV-2 pandemic spurred the U.S. Food & Drug Administration (FDA) to utilize the Emergency Use Authorization (EUA) procedure more than ever before. The pandemic pushed the relatively obscure procedure into public consciousness, making it a frequent topic of discussion and debate. The EUA procedure permits the FDA Commissioner to authorize the introduction of drugs, devices, or biological products into interstate commerce for use in an actual or potential emergency. To issue an authorization, the FDA Commissioner must determine that it is “reasonable to believe,” based on the “totality of the evidence,” that the product “may be effective.” This standard …

Socially Distant Signing: Why Georgia Should Adopt Remote Will Execution In The Post-Covid World, Jessie Daniel Rankin

Georgia Law Review

In the wake of the COVID-19 pandemic, Georgia Governor Brian Kemp and other state governors issued emergency executive orders authorizing the attestation and execution of wills, trusts, and other testamentary documents through the use of audio-video technology. Most states have traditionally required that such testamentary documents be signed in the physical presence of two or more witnesses to be valid. Georgia’s executive order permits these witnesses to instead observe the signing via video-conferencing software, alleviating the requirement that the witnesses be physically present with the testator. This authorization, however, only exists through this executive order and could lapse or be …

Boom Or Bust: Ensuring The Georgia State-Wide Business Court Fulfills Its Constitutional Promise, Roya Naghepour

Georgia Law Review

The United States judiciary includes specialized court systems within its baseline civil and criminal justice structure that provide more efficient and expert adjudication in a wide variety of areas. Since the creation of the Delaware Court of Chancery in 1792, many states have established specialized business courts with jurisdiction over commercial and corporate disputes. Today, many states have business court models, all choosing to employ some version of a specialized forum for corporate and commercial issues for the sake of judicial efficiency. The Georgia State-wide Business Court was established in 2019 with limited jurisdiction over narrow categories of commercial disputes. …

Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Power systems are getting more complex than ever and are consequently operating close to their limit of stability. Moreover, with the increasing demand of renewable wind generation, and the requirement to maintain a secure power system, the importance of transient stability cannot be overestimated. Considering its significance in power system security, it is important to propose a different approach for enhancing the transient stability, considering uncertainties. Current deterministic industry practices of transient stability assessment ignore the probabilistic nature of variables (fault type, fault location, fault clearing time, etc.). These approaches typically provide a conservative criterion and can result in expensive …

Video Snapshot: Single Image Motion Expansion Via Invertible Motion Embedding, Qianshu Zhu, Chu Han, Guoqiang Han, Tien-Tsin Wong, Shengfeng He

Research Collection School Of Computing and Information Systems

Unlike images, finding the desired video content in a large pool of videos is not easy due to the time cost of loading and watching. Most video streaming and sharing services provide the video preview function for a better browsing experience. In this paper, we aim to generate a video preview from a single image. To this end, we propose two cascaded networks, the motion embedding network and the motion expansion network. The motion embedding network aims to embed the spatio-temporal information into an embedded image, called video snapshot. On the other end, the motion expansion network is proposed to …

Infinite Time Horizon Safety Of Bayesian Neural Networks, Mathias Lechner, Dorde Zikelic, Krishnendu Chatterjee, Thomas A. Henzinger

Research Collection School Of Computing and Information Systems

Bayesian neural networks (BNNs) place distributions over the weights of a neural network to model uncertainty in the data and the network’s prediction. We consider the problem of verifying safety when running a Bayesian neural network policy in a feedback loop with infinite time horizon systems. Compared to the existing sampling-based approaches, which are inapplicable to the infinite time horizon setting, we train a separate deterministic neural network that serves as an infinite time horizon safety certificate. In particular, we show that the certificate network guarantees the safety of the system over a subset of the BNN weight posterior’s support. …

Towards Non-Intrusive Camera-Based Heart Rate Variability Estimation In The Car Under Naturalistic Condition, Shu Liu, Kevin Koch, Zimu Zhou, Martin Maritsch, Xiaoxi He, Elgar Fleisch, Felix Wortmann

Research Collection School Of Computing and Information Systems

Driver status monitoring systems are a vital component of smart cars in the future, especially in the era when an increasing amount of time is spent in the vehicle. The heart rate (HR) is one of the most important physiological signals of driver status. To infer HR of drivers, the mainstream of existing research focused on capturing subtle heartbeat-induced vibration of the torso or leveraged photoplethysmography (PPG) that detects cardiac cycle-related blood volume changes in the microvascular. However, existing approaches rely on dedicated sensors that are expensive and cumbersome to be integrated or are vulnerable to ambient noise. Moreover, their …

The Investigations Of Nps Modulated Immunity And Immunometabolism, Brittney Leigh Ruedlinger

Biomedical Sciences Theses & Dissertations

Cancers remain in the top noncommunicable diseases responsible for premature mortality. The heterogeneity among cancers and within tumors makes treating them ever more challenging. Our misfortune for developing cures is mocked by cancer, with the lowest probability of success (PoS) through clinical trials and FDA approval. At the basic level, there are generally two broad gaps impeding cancer eradication: the unidentified shared mechanism(s) exploited by all cancers and the therapeutic approach to intervene. Nanosecond pulse stimulation (NPS) offers a unique approach since its broad impacts intersect those often hijacked by oncogenesis. Metabolic pathways, known for dysfunctions among cancers, share a …
