The Seedling, Caden Bent

2026 Research Poster Competition

This research investigates attainable housing for the missing middle through the integration of mass timber construction, prefabrication, and biophilic design. The project proposes a modular housing system that leverages the structural efficiency, quality control, and ecological performance of mass timber while emphasizing replicability as a means of adaptability rather than uniformity. Through prototyping modular systems, material life cycle studies, and iterative design across replicable and adaptable units, the study examines how prefabrication can accelerate construction timelines without erasing local, cultural, or temporal specificity. Central to the research is an expanded understanding of biophilia, not as applied aesthetic, but as a …

Evaluating High-Strength Steel Welded Connections For Future Aws Welding Standards, Parker Minter

2026 Research Poster Competition

Welding plays a critical role in many civil engineering applications as it is a common method used to connect structural steel components. Because of how widespread the practice is, the American Welding Society (AWS) has developed a set of standardized welding guidelines to ensure consistent quality in structural welds. These standards allow common weld types to be fabricated using pre-approved procedures (e.g. welding materials, temperatures, and positions). Recently, high-strength structural steels have begun to be available domestically. Current AWS standards do not allow for high strength steels (yield strength greater than 80ksi) and need to be evaluated for the inclusion …

Coordinating The Layers: Regulation Of Peptidoglycan Synthesis And Cell Wall Assembly In Mycobacterium Smegmatis By Murj And Pgfa, Karen Emmanuella Samaga-De-Tembiwa

Biology Dissertations

The mycobacterial cell envelope consists of three covalently linked layers whose synthesis must be coordinated to maintain structural integrity during polar growth. While the biosynthetic enzymes for each layer are well characterized, the molecular mechanisms that coordinate synthesis across layers have remained poorly understood. This thesis investigates two essential transmembrane proteins, PgfA and MurJ, that regulate peptidoglycan metabolism in Mycobacterium smegmatis and provide new insight into how mycobacteria synchronize cell wall assembly.

We present evidence that PgfA functions as a bifunctional regulator that links peptidoglycan metabolism to the availability of trehalose monomycolate (TMM), a key mycolic acid precursor. Through epistasis …

The Triple A Approach: Educating Perinatal Clinicians About Trauma Informed Care, Destiny Rosado, Liza Lukasheva

Improving Registered Nurses’ Knowledge In Impulsivity Assessment: An Educational Intervention In Adolescent Mental Health Care, Nein-En Cheng

Doctor of Nursing Practice Projects

Adolescent impulsivity is linked to an increased risk of self-harm, which is associated with higher morbidity and suicide. However, impulsivity assessments are not routinely implemented at the adolescent residential treatment setting. The Barratt Impulsiveness Scale-Brief (BIS-Brief) is a validated tool for identifying individuals at an increased risk of self-harm. The purpose of this Doctor of Nursing Practice (DNP) project was to implement an educational program on adolescent impulsivity, self-harm, and the BIS-Brief, and to evaluate its impact on registered nurses’ (RNs’) knowledge. A quasiexperimental one-group pretest-posttest design was used in an adolescent residential treatment facility. Seven RNs participated in the …

Biases In Prescribing Practices: Examining Physician Stereotyping In Women's Health Counseling Based On Patient Race And Perceptions Of Promiscuity, Jessica Lobb

2026 Research Poster Competition

As modern healthcare moves towards a focus on personalized medicine, an evaluation of current provider practices is essential to evaluating quality of care. Numerous studies have shown that physicians exhibit stereotyping and implicit bias with patients, but much remains unknown about the extent this impacts women’s health counseling. The presence of stereotyping could affect women’s health outcomes, as decisions such as choosing to prescribe hormonal contraceptives have numerous physical and emotional side effects. This study aimed to assess how stereotyping contributes to physicians’ perceptions and medical decisions for women seeking gynecological care. Clinical vignettes were given to physicians showing women …

Monitoring Long-Term Water Quality Benefits Of Urban Stream Restoration, Kira Burnett

2026 Research Poster Competition

Urbanization without conscious environmental planning can result in the degradation of stream ecosystems. This tends to result in urban stream syndrome, which is often characterized by increased sediment and nutrient concentrations, decreased biodiversity, more frequent flash flooding, and overall water quality degradation. As such, stream restoration practices are often implemented to address urban stream syndrome. Commonly used restoration practices include applying natural channel design to stabilize eroding stream banks and establishing diverse streamside vegetation to filter pollutant inputs. However, the benefits of restoration are not often quantified due to a lack of post-restoration monitoring, making it challenging to determine what …

Developing Bioassays For Detection Of Residual Herbicides In Compost, Esther Moore

2026 Research Poster Competition

Developing Bioassays for Detection of Residual Herbicides in Compost, the use of synthetic herbicides has dominated the field of agricultural production for over a century. While synthetic herbicide use has resulted in an undeniable boost in agricultural productivity, risks such as environmental degradation and reduced yield of non-target plant species must be considered. Key among these risks is compost contamination, especially from persistent herbicides. After these herbicides are applied, they are absorbed by growing vegetation, consumed by herbivores, passed through the digestive tract, and reintroduced into soil manure based compost. Even after this process, chemicals in such herbicides can remain …

Disrupted Circadian Rhythms Affect Hallmark Pathologies In Alzheimer’S Disease-Related Mouse Models, Valeria Buzinova

Theses and Dissertations--Molecular and Cellular Biochemistry

Alzheimer’s Disease (AD) is a complex neurodegenerative disease with two hallmark pathologies: extracellular amyloid-b (Ab) and intracellular neurofibrillary tangles (NFTs). Ab is proteolytically processed from amyloid precursor protein (APP) by b-secretase and g-secretase as a monomeric peptide prone to aggregation. Eventually, the aggregate-prone monomers will form dense plaques that are difficult to break down and remove. These plaques begin to deposit into the cortex decades prior to the formation of NFTs and the onset of cognitive decline. NFTs are comprised of hyper-phosphorylated tau. Tau is a protein that serves to promote and stabilize the formation of microtubules. The formation of …

Duties To Yourself, Julian Sommers

2026 Research Poster Competition

I will be writing a thesis paper with the guidance of Dr. Purdy so I can graduate from the honors program with a bachelor's within philosophy. This paper is still very much in the planning stages, but we have a rough idea of what it will look like. The broad topic is moral duties one could have to themselves and potentially how that relates to duties you might have to others as well. We are interested in this project because I believe our common idea of morality excludes the self from being regarded as a person. I believe morality focuses …

Modeling The Development Of Keyhole Passage Morphology, Charlotte Boehme

2026 Research Poster Competition

Cave passage morphology is an important indicator of the hydrological conditions under which a cave passage was formed. Keyhole passages are a commonly occurring type of passage morphology that consists of a round, wide top with a smaller canyon incised in the bottom of the passage. These passages typically indicate a shift from fully water-filled to partially water-filled conditions. There are multiple mechanisms by which such a transition can occur, and little is understood about which of these mechanisms is most common, or whether aspects of keyhole passage morphology may indicate the primary formation mechanism. CaveCHAMP is a physically based …

Feminist Aesthetics: The Early Ms. Years And Second-Wave Body Politics, Meghan Lucas

2026 Research Poster Competition

Despite its tremendous impact on both second-wave feminist organizing and women's political consciousness, Ms. magazine remains understudied by scholars interested in emergent feminist consumers and emergent feminist citizens. This study aims to fill the gap in scholarship around late 20th century periodical studies by offering content analysis of the first two years of Ms., July 1972 to June 1974 to offer a content analysis of second-wave feminism's foray into magazine culture and understand how Ms. articulated feminist politics, feminist writing, and women's consumer power to raise women’s consciousness. My research was focused on the archival issues from July 1972 to …

Optimizing Microscale Tesla Valve Design For Enhanced Efficiency For Filtering And Sorting Bacteria, Brian Ewalt

2026 Research Poster Competition

Invented by Nikola Tesla in 1920, a Tesla valve is a passive check valve with no moving parts but showing diodicity for fluids (i.e., allowing fluids to flow easily in one direction but not in the other). Tesla valves have demonstrated remarkable versatility across a range of scientific fields. Recently, a study conducted at the University of Arkansas showed that these conduits exhibited diodicity for bacteria in the absence of fluid flows (Rogers et al. 2023), serving as proof of concept for applying microscale Tesla valves for filtering and sorting bacteria and microorganisms in biomedical settings. However, the design of …

The Log Cabin | Public Perception And Mediated Reality (1840 – 1980), Aspen Regan

2026 Research Poster Competition

This capstone examines the evolution of the log cabin from 1840 to 1980. At its core, the project questions the legacy of the log cabin from its origins as simply being a traditional dwelling typology to its establishment as a cultural icon or rather, an enduring vessel foundational to the American Dream and ideals of self-reliance, freedom, and individualism deep within the heart of American culture. Various case studies, traditional literature review, and archival analysis was required to complete and produce a comprehensive study of the log cabin and its history in this context, culminating into three distinct chapters. Chapter …

Chronostratigraphy Using Stable Carbon Isotopes Of The Elliot Formation, South Africa, Aidan Del Pino

2026 Research Poster Competition

The Elliot Formation in South Africa preserves a fossil-bearing record spanning the Late Triassic–Early Jurassic, a time marked by significant environmental changes related to the Central Atlantic Magmatic Province (CAMP) and the end-Triassic extinction event. Despite its importance, the Elliot Formation remains poorly constrained due to limited chronostratigraphic markers. Chronostratigraphy is the branch of geology that correlates and dates rock units in time, allowing researchers to arrange these rock units into a chronological sequence. Globally, the Triassic–Jurassic boundary is characterized by a pronounced negative carbon isotope excursion linked to CAMP volcanism and the end Triassic extinction event. This C-isotope excursion …

Temporal Variational Graph Autoencoder For Influenza Evolution, Soumya Chauhan

2026 Research Poster Competition

Frequent mutations in influenza virus surface proteins can increase infectivity while evading human and vaccine immunity, causing seasonal epidemics. The CDC annually evaluates thousands of virus strains to predict mutated sequences likely to be dominant in the next season, which creates a need for methods that better capture how viral mutations evolve over time. In this study, we represent influenza protein sequences as a network-like graph, creating connections if sequences are collected a week apart and only differ by one mutation. This method explicitly considers time information as part of the evolution, while other existing methods analyze mutated sequences without …

Rekindling Hearth: An Investigation And Discussion Of The Traditional And Evolving Roles Of Hearth In Architecture, Ruth Prenzler

2026 Research Poster Competition

This research explores the evolving role of the hearth in domestic architecture, examining its historical significance and its continuing symbolic, spatial, and architectural relevance. Once essential for heat, cooking, and social gathering, the hearth has gradually shifted from a functional necessity to a largely symbolic and nostalgic artifact as a result of technological advancements and changing domestic lifestyles. Despite this functional decline, the hearth persists as a powerful cultural and architectural element, deeply embedded in collective memory and the perception of home. This study reexamines the hearth’s spatial, social, and functional roles through a combined methodology of literature review, theoretical …

Hostile But Lawful? Examining The Elements Of “True Threats” In Rhetoric Toward Election Officials, Kayleigh Gwiazdowski

2026 Research Poster Competition

Threats of violence have become increasingly visible, yet they remain understudied compared to acts of violence themselves. This project examines death threats directed at U.S. election administrators following the 2020 Presidential Election. Drawing on qualitative interviews with 26 current and former U.S. election administrators, I analyzed 580 hostile messages received in the aftermath of the election to understand how threats function as a tool of intimidation and coercion. Messages were examined for markers indicating (1) whether the sender expressed the intent to threaten, (2) whether the language specified a concrete act of violence or identifiable target, and (3) whether a …

Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison

2026 Research Poster Competition

The cattle industry in Arkansas plays a significant role in the state’s agricultural economy; however, two emerging infectious diseases pose a threat to cattle health, producer livelihood, and animal welfare. The two diseases, anaplasmosis and theileriosis, are caused by organisms that enter the host’s bloodstream and infect red blood cells, leading to destruction of said cells. The shared symptoms of both diseases are fever, weakness, anemia (low red blood cell count), reduced productivity, weight loss, and possibly death. An important difference between symptoms is that, unlike anaplasmosis, theileriosis can cause abortion in cattle. Both diseases are known to spread through …

Uav-Based Sensor Integration For In-Situ Lake Water Quality Monitoring, Alec Campbell

2026 Research Poster Competition

Current water quality assessment methods rely heavily on manual sampling and laboratory analysis, which are time-consuming and difficult to perform in remote or hazardous environments. In surface water monitoring, spatial and temporal resolution is often constrained by labor, access, and logistical limitations of manual sampling programs. This research aims to develop a drone-based system for real-time, in situ lake water quality monitoring. To address these challenges, the project focuses on integrating multiple water quality sensors, including oxidation-reduction potential (ORP), pH, electrical conductivity (EC), turbidity, and a multispectral spectrometer, into a compact, UAV-compatible design capable of collecting spatially referenced data. Methods: …
