Impacts Of Nutrient Addition And Disturbance On Coastal Dune Arthropod Communities And Trophic Interactions, Kayla Beitzel

Graduate Theses and Dissertations (2019 - present)

Coastal dune ecosystems face ongoing threats from human-mediated disturbance and altered resource availability. Because these dunes provide critical habitat for many organisms, including shorebirds, beach mice, and arthropods, changes in disturbance regimes or resource availability can impact plant communities and higher trophic levels by altering plant richness and productivity, which in turn influence arthropod abundance and diversity. To examine how disturbance and nutrient addition affect arthropod communities, we established twenty 5×5 m plots on Dauphin Island, crossing mechanical disturbance with a 10 g m⁻² addition of nitrogen, phosphorus, and potassium, replicated across five experimental blocks. Arthropods were sampled using three …

Climate Science And Natural Resource Litigation, Jessica A. Wentz

Sabin Center for Climate Change Law

Climate change has major implications for sustainable use and conservation of natural resources. Many natural systems are already under severe stress and may be unable to sustain historical use patterns; resource management decisions can also exacerbate or mitigate climate change by affecting the balance of greenhouse gases in the atmosphere. This Article describes the legal and scientific basis for recognizing agencies’ obligations to assess and respond to climate change, drawing insights from a survey of U.S. litigation involving forests, fisheries, rangelands, and freshwater resources. The cases suggest litigants have been somewhat successful in driving more rigorous assessments of climate change. …

Using Scenario-Based Design Activities To Explore Sociotechnical Thinking In Engineering Professionals, James M. Whealan

Master's Theses

Sociotechnical thinking is the ability to recognize the interconnectedness of both technical and non-technical dimensions such as environmental, economic, social, cultural, and political factors. Although traditional engineering curriculum often emphasizes technical knowledge and skills, research suggests that engineering work is inherently sociotechnical. While sociotechnical thinking is a critical engineering skill, relatively little is understood about the nature of it or the different aspects comprised within it. To that end, this study addresses the following research question: What sociotechnical factors do engineering professionals consider in a collaborative scenario-based design activity? To answer this question, we conducted a qualitative study of engineering …

Probing Tau Citrullination In Alzheimer’S Disease Brains And Mouse Models Of Tauopathy, Huimin Liang, Jerry B. Hunt, Chao Ma, Andrii Kovalenko, John Calahatian, Cecelie Pedersen, Haiying Liu, Junyan Li, Malina Serrano, Danielle Blazier, Mallory Watler, Patricia Rocha-Rangel, Christopher Saunders, Laura J. Blair, Leonid Breydo, Kevin Nash, Zainuddin Quadri, Brian Kraemer, Peter Nelson, Christopher Norris, Erin L. Abner, Vladimir N. Uversky, Dale Chaput, Maj Linda B. Selenica, Daniel C. Lee

Epidemiology and Environmental Health Faculty Publications

Alzheimer’s disease (AD) includes a defining hallmark that correlates most closely to cognitive decline, namely misfolded tau protein. However, the “upstream” etiology and downstream clinical manifestations of tauopathies are quite diverse. Tau deposition elicits different pathological phenotypes and outcomes depending on the tau strain, proteoforms, and regional susceptibility. Posttranslational modifications (PTM) can alter tau structure, function, networks, and its pathological sequelae. We uncovered tau citrullination on multiple epitopes caused by peptidyl arginine deiminase (PAD) enzymes. PAD-induced citrullination irreversibly converts arginine residues to citrulline, producing a net loss of positive charge, elimination of pi–pi interactions, and increased hydrophobicity. We observed increased …

These Yellow Stars Of Ours, Vinh Hong Nguyen

Theses

These Yellow Stars of Ours is an experimental documentary that traces the intertwined histories of Thaun and Nam Nguyen as they flee war-torn Vietnam, fall in love, and build a life in Western New York. Through their accounts and those of their two sons, the film explores the complexities of generational trauma and the ongoing experience of bicultural straddling—the negotiation between inherited Vietnamese identity and the shaping influence of an American upbringing. The project examines how trauma, memory, and cultural displacement circulate across generations, shaping identity in both visible and invisible ways. Methodologically, the film is structured around the conceptual …

Achilles, Sreelekha Samala

Theses

ACHILLES is a speculative design project and conceptual artifact. It is not intended to function as a medically certified or biomechanically operational prosthetic arm. Instead, it operates within the realm of design research, using visual realism and luxury aesthetics to explore how assistive technologies could be perceived differently in cultural, emotional, and commercial contexts. Using 3D software to experiment with color, pattern, and texture, I designed a realistic mockup to demonstrate how Achilles could appear in a high-end commercial setting. Instead of animating the model, I focused on camera motion to highlight the prosthetic from multiple angles, emphasizing its sculptural …

Mercurial, Bhavana Neti

Theses

Mercurial is a groundbreaking visual journey through typography that charts the fluid and often volatile passage, from the depths of sadness, eventually finding the light in the end, inspired by the song title Louder than Bombs by BTS, a Korean boyband. Over a carefully observed period, this book captures the subtle and dramatic transformations of emotion through a unique lens. "Mercurial" represents a unique and multi-layered approach to understanding and visualizing emotions. Initially, the exploration of shapes as a representational tool proved inadequate for capturing this complexity. This led to a pivotal shift towards typography, where the inherent qualities of …

By requiring at least two users to operate its see-saw mode, Tandem counteracts …

Hyaluronic Acid Loaded With Aloe Vera-Derived Extracellular Vesicles: A New Bioactive Approach For Fibrotic Scarring, Maria Camila Ceballos Santa

Theses

Disruptions in wound healing can result in pathological outcomes ranging from chronic nonhealing wounds to excessive fibrotic scarring. Hypertrophic scars and keloids are hallmarks of this dysregulation, characterized by abnormal collagen deposition, persistent myofibroblast activation, and disorganized extracellular matrix (ECM) remodeling. Chronic inflammation and oxidative stress play central roles by increasing reactive oxygen species (ROS), which damage essential macromolecules and sustain pro-inflammatory signaling, while promoting the transdifferentiation of fibroblasts into myofibroblasts and the excessive production of ECM proteins, such as collagen and α-smooth muscle actin (α-SMA). This fibrotic cascade leads to tissue stiffness, contractility, and disfigurement, affecting the well-being of …

Biology Faculty Publications

Lemurs are often cited as an example of adaptive radiation, as more than 100 extant species have evolved and filled ecological niches on Madagascar. However, recent work suggests that lemurs lack a hallmark of other adaptive radiations: explosive speciation rates that decline over time. Thus, characterizing the tempo and mode of evolution in lemurs can reveal alternative ways that hyperdiverse clades arise over time, which might differ from traditional models. We explore lemur evolution using a phylogenomic dataset with broad taxonomic sampling that includes the lorisiforms of Asia and continental Africa. Our analyses reveal multiple bursts of diversification (without subsequent …

Carbon Sequestration And Greenhouse Gas Emission Dynamics Of Forage Sorghum Cultivars In Southern Texas, Kusalika Madushani Kularathna

Carbon sequestration is one of the major strategies for removing atmospheric carbon dioxide and fixing it in the soil and plants. The research study focused on the carbon sequestration and greenhouse gas dynamics of three different forage sorghum cultivars: Sugar Graze Ultra (annual), PSH20TX01 (perennial seeded), and PSH09TX15 (perennial rhizomes), in Southern Texas, where each cultivar had nine plots. The field study was conducted over two growing seasons, in 2024 and 2025, at the Prairie View A&M University research farm. Three different fertilizer rates, recommended, half-recommended, and zero fertilizer rates, were applied. Soil greenhouse gas emissions were measured using a …

Lynk Labs: How The Least-Vetted Documents Destroy Issued Patents, Dennis D. Crouch

Faculty Publications

The Lynk Labs petition presents the Supreme Court with an opportunity to restore the temporal coherence that Congress built into § 311(b)'s evidentiary framework. By treating "printed publication" as synonymous with any reference that eventually becomes public, the Federal Circuit has transformed IPR into a forum where unexamined, abandoned patent applications can destroy patents that survived the very scrutiny those applications failed to complete. The Court should grant certiorari and hold that a printed publication must be printed and published before the critical date to serve as the basis for an IPR challenge.

Linking Climate And Demography To Predict Population Dynamics And Persistence Under Global Change., Jennifer L. Williams, Amy L. Angert, Aldo Compagnoni, Ali Campbell, Megan L. Demarche, Margaret E K Evans, Joshua C. Fowler, Amy M. Iler, Jenna A. Loesberg, Allison M. Louthan, Scott W. Nordstrom, Multiple Additional Authors

Publications, Reports and Presentations

Predicting the effects of climate change on plant and animal populations is an urgent challenge for understanding the fate of biodiversity under global change. At the surface, quantifying how climate drives the vital rates that underlie population dynamics appears simple, yet many decisions are required to connect climate to demographic data. Competing approaches have emerged in the literature with little consensus around best practices. Here we provide a practical guide for how to best link vital rates to climate for the purposes of inference and projection of population dynamics. We first describe the sources of demographic and climate data underlying …

“War Is God” And “Unguessed Kinships”: Blood Meridian And Cormac Mccarthy’S “Border Tetralogy”, Seth Reeves

Electronic Theses and Dissertations

This thesis applies the metaphysics of philosopher Gilles Deleuze to Cormac McCarthy’s novel Blood Meridian, arguing that the novel initiates a thread of immanent subjectivity that unfolds throughout the Border Trilogy that follows it. Against a hierarchical metaphysics of transcendence, specifically an inverted Platonic Idealism, Blood Meridian dramatizes an immanent world of “optical democracy,” a prose style that levels the human and nonhuman and eludes subject and object categories. The kid’s autonomy from Judge Holden’s violent domination marks the truncated beginning of a Deleuzian subjectivity of becoming-other and immanent kinship. This incomplete gesture continues in the Border Trilogy, where …

Mass Spectrometry- And Genomic-Based Characterization Of Novel Glycosphingolipid-Producing Bacteria And Their Glycosyltransferases, Tahir Ali

Electronic Theses and Dissertations

Glycosphingolipids (GSLs) are a type of membrane-lipids commonly found in eukaryotes, as well as in bacteria from the order Sphingomonadales. In these bacteria, GSLs replace lipopolysaccharides as key structural and functional components of the outer membrane. These molecules play a crucial role in maintaining membrane integrity and helping bacteria adapt to environmental stresses. Additionally, they hold significant potential in biomedical research due to their ability to modulate the immune response through interactions with the CD1d receptor. Despite their important biological and biomedical roles, the diversity and biosynthesis of bacterial GSLs are far less understood compared to their eukaryotic counterparts. In …

Background: The immature lungs of very preterm infants are exposed to supraphysiologic oxygen, contributing to bronchopulmonary dysplasia (BPD), a chronic lung disease that is the most common morbidity of prematurity. While the microbiota significantly influences neonatal health, the relationship between the intestinal microbiome, particularly micro-eukaryotic members such as fungi and yeast, and lung injury severity in newborns remains unknown. Results: Here, we show that the fungal microbiota modulates hyperoxia-induced lung injury severity in very low birth weight premature infants and preclinical pseudohumanized and altered fungal colonization mouse models. Instead of fungal communities dominated by Candida and Saccharomyces, the first stool …

Reinsuring Ai: Energy, Agriculture, Finance & Medicine As Precedents For Governance Of Frontier Artificial Intelligence, Nicholas Stetler

Southern Illinois University Law Journal

Federal reinsurance for advanced artificial intelligence offers a credible foundation for managing risk at scale. Traditional legal tools such as regulation, litigation, and voluntary guidelines, lack the institutional capacity to address deep uncertainty, widespread spillover effects, and low-probability but catastrophic harms. A public financial infrastructure distributes risk, incentivizes responsible development, and enables earlier detection of emerging threats. Precedent exists in nuclear energy, agriculture, healthcare, and finance, where federal reinsurance enabled markets to function despite underlying volatility. The same institutional logic applies to frontier AI.

Part I explains how general-purpose and frontier AI models work, and why they have become a …
