Developing Guidance For The Use Of Floating Treatment Wetlands In Brackish Stormwater Ponds, Clare Escamilla

All Dissertations

Stormwater ponds are commonly used as a flood control strategy, particularly in coastal developments. Many coastal stormwater ponds are impaired with high nutrient levels that can lead to algal blooms, impacting the water quality of the pond and surrounding ecosystem. Floating treatment wetlands (FTWs) are one potential strategy that can be implemented in stormwater ponds to reduce high nutrient concentrations, however limited research has been done in brackish waterbodies. To determine the suitability of using FTWs in brackish stormwater ponds this research focused on (1) coastal resident perceptions of FTWs and (2) plants that can be utilized in FTWs deployed …

Truth, Justice, And The American Way: Negotiating Identity Among Superhero Cosplayers At International Comic Book Conventions, James Scanlan

Graduate Theses and Dissertations

Cosplay performances in convention spaces, and the increasing commercialization and commodification of both, remain largely unexplored domains that are rapidly expanding into global phenomena. The influx of capital internationally and the growing popularity of cosplay and conventions offers the opportunity to document and describe processes of performance, identity construction, and negotiation of the global phenomena within local contexts (“glocalization”) in non-Western spaces. I conducted ethnographic research at more than half a dozen research sites throughout Europe, the Middle East, South Asia, East Asia, and South and Central America, photographing convention spaces and cosplayers and conducting interviews with cosplayers. By focusing …

Onward, Christian Soldiers: The Material Rhetoric Of Becoming Fascist In Parachurch Scouting Organizations, Madeline Aubrey Studebaker

Graduate Theses and Dissertations

This thesis provides a material rhetorical analysis of Trail Life USA and American Heritage Girls, two Christian nationalist scouting organizations that aim to renew and restore their cultural dominance across America. In examining how these programs route children’s bodies through ritual and affective indoctrination, I find that a fascist becoming underpins these groups’ (re)production of perfect, patriotic children. The first chapter discusses how boys enrolled in Trail Life USA become fascist as self-defense against American boyhood’s perceived eradication. Trail Life USA restores masculinity through rituals of autogenetic sovereignty, returns to originality through homosocial and affective intensity, and invocations of exceptional …

Intention To Take Pre-Exposure Prophylaxis (Prep) As An Hiv Preventive Medication: An Application Of The Health Belief Model And Theory Planned Behavior, Besuthu Nakekelwa Nkambule

Graduate Theses and Dissertations

South Africa (SA) has 7.7 million citizens (12.6% of its 2023 population) living with human immunodeficiency virus (HIV). The use of pre-exposure prophylaxis (PrEP) as an antiretroviral medication for HIV-negative individuals is a promising HIV prevention strategy in SA that can help the attainment of an HIV free generation. PrEP offers greater than 90% protection against HIV acquisition. Despite SA’s efforts in increasing PrEP coverage for its citizens, primarily to those at substantial risk, its adoption remains relatively low. Structural barriers related to access, costs, lack of awareness, and, more recently, US funding cuts exacerbate the challenges of PrEP’s potential …

Longitudinal And Bidirectional Relations Between Problematic Social Media Use And Cognitive Failures, K. T. A. Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

With social media becoming increasingly pervasive in our daily lives, there have been heightened concerns that the distractions caused by compulsive and problematic social media use may lead to cognitive failures. While some preliminary work have explored the link between problematic social media use and cognitive functioning, most are cross-sectional, leaving it uncertain whether cognitive failures are a precursor or consequence of problematic social media use. To address this gap, the current study examines the bidirectional relationship between problematic social media use and cognitive failures. A sample of 252 young adults completed the Problematic Social Media Use Scale and the …

Causalabstain: Enhancing Multilingual Llms With Causal Reasoning For Trustworthy Abstention, Yuxi Sun, Aoqi Zuo, Wei Gao, Jing Ma

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) often exhibit knowledge disparities across languages. Encouraging LLMs to abstain when faced with knowledge gaps is a promising strategy to reduce hallucinations in multilingual settings. Current abstention strategies for multilingual scenarios primarily rely on generating feedback in various languages using LLMs and performing self-reflection. However, these methods can be adversely impacted by inaccuracies and biases in the generated feedback. To address this, from a causal perspective, we introduce CausalAbstain, a method that helps LLMs determine whether to utilize multiple generated feedback responses and how to identify the most useful ones. Extensive experiments demonstrate that CausalAbstain effectively …

Role Of Social Media Mindfulness In Combatting Fake News Propagation, Gaurav Bansal, Fiona Fui-Hoon Nah, Jason B. Thatcher

Research Collection School Of Computing and Information Systems

The dissemination of fake news by social media users is a key factor in the escalation of misinformation. Research suggests that social media networks are becoming increasingly homophilic, which leads to an overreliance on social media friends that contributes to the spread of fake news. However, little is known about how social media mindfulness can reduce the sharing of fake news. To investigate this research question, we conceptualized a social media mindfulness construct and developed the social media mindfulness scale. We also hypothesize that social media mindfulness lowers overreliance on friends’ knowledge, which increases skepticism about social media news that …

This dissertation addresses the critical challenge of adversarial robustness in deep learning systems, focusing on two fundamental domains: time-series prediction and object detection. As these AI systems become increasingly deployed in safety-critical applications from power grid management to autonomous vehicles their vulnerability to adversarial attacks poses significant risks to infrastructure and human safety.

The first contribution introduces a novel stealthy black-box False Data Injection (FDI) attack specifically designed for quasi-periodic time-series data. Unlike existing attacks that produce easily detectable anomalies, our method generates adversarial perturbations that preserve the underlying periodicity and statistical properties of the data, effectively bypassing traditional anomaly …

Trophic Roles And Climate-Driven Vulnerability For Benthic Invertebrates At Artificial Reefs In The Northern Gulf Of Mexico, Amanda Kirkland

LSU New Orleans Theses and Dissertations

Artificial reefs are deployed to enhance marine habitats and fisheries, yet their role in supporting secondary production and their vulnerability to climate stressors remain understudied. This dissertation investigates the trophic ecology and climate sensitivity of benthic invertebrates at artificial reefs in the northern Gulf of Mexico. Chapter 1 assessed reef food webs using stable isotopes from fishes, invertebrates, and primary producers across six reefs and two seasons. Mixing models showed that most fishes rely on benthic reef carbon, while suspension feeders consume plankton and sediment microphytobenthos. Isotopic niche analysis revealed functional diversity and seasonal shifts in δ¹³C and δ³⁴S, though …

Real-Time Fiducial Marker Based Localization For Autonomous Unmanned Aerial Vehicle Navigation, Sourav Raxit

LSU New Orleans Theses and Dissertations

By harnessing fiducial markers as visual landmarks in the environment, Unmanned Aerial Vehicles (UAVs) can rapidly build precise maps and navigate spaces safely and efficiently, unlocking their potential for fluent collaboration and coexistence with humans. Existing fiducial marker methods rely on handcrafted feature extraction, which sacrifices accuracy. On the other hand, some deep learning pipelines for marker detection fail to meet real-time runtime constraints crucial for navigation applications. In this work, I propose YoloTag- a real-time fiducial marker-based localization system. YoloTag uses a lightweight YOLO v8 object detector to accurately detect fiducial markers in images while meeting the runtime constraints …

Elucidating The Mechanisms Underlying A Functional Plant-Arbuscular Mycorrhizal Symbiosis Using Omics Approaches, Jasmine Gill

All Dissertations

Arbuscular mycorrhizal fungi (AMF) are obligate biotrophs forming symbiotic association with plants. The plant-AMF symbiosis has gained much attention due to its ability to improve plant nutrient uptake, especially phosphorus, which is often inadequately available to plants due to its limited mobility and complex formation in many soils. Phosphorus (P) is a crucial nutrient for plants, and most phosphate fertilizers are derived from phosphate rock, a finite natural resource. Thus, optimizing P uptake is vital for sustaining crop yields and addressing the needs of a growing global population. Plant-AMF symbioses are significant in this context, as AMF can acquire P …

Internal data collection boosts adoption, while third-party sharing reduces it, reflecting behavioral loss aversion. Security disclosures moderate these effects by …

Coding Manual: Analyzing Semistructured Interview Data For Master Narratives, Jayson Seaman, Cindy Hartman, Andrew D. Coppens

Faculty Publications

This coding manual accompanies a methodological reorientation in narrative identity research, one that challenges the field’s prevailing “protagonist bias” — the assumption that first-person autobiographical accounts are the primary or most valid source for identifying cultural master narratives as psychological resources. While much psychological research has centered on how individuals narrate their own lives, this approach can obscure the ways that broader cultural narratives are circulated, reinforced, and contested through discourse beyond the self. This method provides researchers with a systematic approach for identifying how master narratives operate across multiple narrative levels, often outside of biographical storytelling.

Identification Of Anti-Inflammatory Pathways Induced By Enterotoxin B Subunits For Use As Therapeutics In Inflammatory Bowel Disease, Hannah Juel Hedelius

Boise State University Theses and Dissertations

Vibrio cholerae’s AB5 enterotoxin, cholera toxin (CT), has a homopentameric, non-toxic B subunit (CTB). CTB is a well-known vaccine adjuvant used for its ability to create a strong immune response, however more recent studies have shown its ability to also behave in an anti-inflammatory manner, performing as a protective agent in a variety of different inflammatory diseases. Escherichia coli (E. coli) produces a heat-labile AB5 enterotoxin (LT) that is very homologous to CT, with its B subunit (LTB) being used in a similar manner as a vaccine adjuvant. There have been many studies comparing LTB to CTB due …

Examination Of Caregiver Supervision Practices And Beliefs Among Caregivers Of Children With Bleeding Disorders, Sophia Noelle Prokos

Dissertations

Abstract: Unintentional injury is the leading cause of death for young children in the United States, and children with chronic medical conditions such as bleeding disorders are at elevated risk for injury and more severe outcomes (Centers for Disease Control and Prevention [CDC], 2021; Mayes et al., 2009; Shen et al., 2016). While caregiver supervision is a known strategy for injury prevention (Damashek & Corlis, 2017; Morrongiello et al., 2011), limited research has examined how supervision beliefs and practices differ for caregivers of children with bleeding disorders. The present study compared caregiver supervision, injury attitudes, and injury history between …

Perceptions Of National Identity And Government Trust: The Effects Of Migrant Education Policies In Thailand, Kathryn Creglow
