Decoding Bacterial Resilience: Srnas And Sigma Factors In Stress Adaptation And Persistence Of Salmonella, Anita Nguyen

Honors Theses

Small RNAs (sRNAs) are noncoding RNA molecules in bacteria that function primarily to regulate gene expression, including those associated with stress. The Borchert Lab has identified 173 sRNAs and > 500 sRNAs that are responsive to desiccation and carbon starvation (c-starvation), respectively. Prokaryotic transcription involves an RNA Polymerase (RNAP) that transcribes DNA into RNA. RNAP involves sigma factors, which recognize promoters for the initial steps of RNA synthesis. The Borchert Lab has determined that there are significant overlaps between sRNAs expressed in cells subjected to both short-term durations and long-term durations of carbon starvation. Salmonella enterica serovars can have outbreaks associated …

Toxicity And Biodegradability Of Novel Boronium Vs Conventional Ammonium-Based Antimicrobial Compounds In Wastewater Treatment Systems, Noor Shalan

Honors Theses

Quaternary ammonium compounds (QACs) are highly effective as disinfectants, herbicides, and pesticides; thus, overuse causes elevated levels of residual toxicity in domestic and industrial wastewater. QACs can be toxic to essential bacteria breaking down pollutants in wastewater treatment plants (WWTPs) and can remain untreated in effluent, harming the environment, and contributing to antibiotic resistance, posing risks to human health. Novel boronium-based antimicrobial compounds have demonstrated efficacy in eliminating bacteria, fungi, and viruses. If the boronium compounds exhibit lower residual toxicity, they could offer a promising alternative to QACs. Because these compounds are still in development, their potential toxicity to the …

The Search For Slow Particles And Magnetic Monopoles With Nova, John Clark

Honors Theses

Singular magnetic poles, north or south, have been theorized to exist for hundreds of years. In the modern day, the elusive singular magnetic pole still remains undiscovered. The appearance of this particle would help confirm many Grand Unified Theories, GUTs, and revolutionize our understanding of some of the fundamental forces of the universe. Fermilab's NOvA collaboration is working on ways to screen and detect magnetic monopoles and other slow-moving particles coming from outer space alongside their main mission to study neutrinos. The aim of this work is to determine and improve the Far Detector’s efficiency at identifying slow moving particles. …

Ghosts In Glass: Ghost Crabs As Judges Of Glass Sand For Coastal Restoration, Emily Parrish

Honors Theses

Over 60% of the Gulf of Mexico coastline is actively eroding, which has resulted in thousands of miles of lost coastline over the last 100 years. This drastic loss of coastal land highlights the dire need for coastal restoration across the entirety of the Gulf Coast. A vital aspect of restoring these eroded areas is replenishing eroded substrate, traditionally conducted through offshore dredging of substrates which comes with high economic and ecological costs. Recycled glass sand may be able to fill this role and reduce our reliance on dredging while lowering the amount of glass waste entering landfills each year. …

Development And Characterization Of A Pro-Angiogenic Peptide Amphiphile For Deep Dermal Burn Healing Via Spray Delivery, Loria Dimartino

Honors Theses

Severe burns and other dermatological injuries are frequently accompanied by a range of comorbidities and aesthetic challenges that patients must contend with. The complexity of burn care is exacerbated by the lack of a standardized surgical protocol, as treatment strategies are tailored to individual patient factors, including overall health status, wound size and location, as well as the expertise and resources available to the surgical team. Most commonly, deep dermal burns are treated through grafting, which effectively covers the injury site, but requires the creation of a second wound on the body of approximately the same size. This produces a …

Fouling-Resistant Voltammetric Xylazine Sensors For Detection Of The Street Drug “Tranq”, Ann Holland Wemple

Honors Theses

As the opioid crisis continues to wreak havoc on a national and global scale, it is increasingly critical to develop methodologies to detect the most dangerous of these drugs as fentanyl and its derivatives have orders of magnitude higher potency than morphine. Recently, the scientific challenge for chemical detection of fentanyl and its derivatives has been complicated by both the constantly increasing synthetic variations of the drug as well as the expanded use of adulterants. One tragically consequential example is the nocuous street drug known as “Tranq” which combines fentanyl or a fentanyl derivative with the veterinary sedative Rompun®, chemically …

Determining The Influence Of A Low-Head Dam On Macroinvertebrate Communities In The Bouie River, Natalie Santiago

Honors Theses

The Bouie River is a tributary of the Leaf River and belongs to the Pascagoula River watershed, the latter of which has no flow impediments in the form of sills or dams. The Bouie River has been heavily altered in the lower 10 river kilometers (rkm) from aggregate mining (creating a series of deep gravel pits) and the presence of an earthen and concrete low-head dam (sill) located 6 rkm from the mouth of the river. However, despite these alterations, the immediate stretch of river below the low-head dam is a known spawning habitat for diadromous fish species, including the …

Implementing Storytelling Into The Elementary School Classroom: A Best Practice Guide With Adaptable Lessons, Cali Reinhart

Honors Theses

Incorporating storytelling projects and activities in the elementary classroom helps students become more engaged and interested in what they are being taught. Often, there is not enough time in the day to cover all the material, let alone teach students these concepts in fun and engaging ways that every student deserves. Therefore, teachers should be given the resources to help their students learn the material in a fun and appealing way, such as through storytelling. Previous research has shown that storytelling is a multisensory project that reinforces literacy and language skills, increases students’ retention of the information presented, and increases …

Evaluating The Effects Of Social Ostracism On Attentional Control And Episodic Memory, Colby Brown

Honors Theses

This study examined the relationships between social pain, attentional control, and episodic memory. Fifty-five University of Southern Mississippi undergraduates (Mage = 19.78 years; Range = 17-29) wrote responses to one of three prompts designed to elicit feelings of social pain, physical pain, or no pain (i.e., control). Participants then completed a battery of attentional control (AC) and episodic memory (EM) tasks consisting of the Stroop squared, Flanker squared, Simon squared, and dual-list recall tasks. Participants also completed a series of questionnaires including Positive and Negative Affect Schedule (PANAS) to assess any change in affect caused by the writing prompts and …

Smoking And Oral Health In The Tipu Maya: A Study Of Nicotine In Dental Calculus, Emily Byrd

Honors Theses

Tobacco smoking was a deeply rooted tradition in Maya society, often associated with ritual and daily life, and may have contributed to patterns of dental health. However, despite its cultural significance, direct biological evidence of tobacco use in ancient populations is rare. This study addresses that gap by analyzing nicotine residues preserved in dental calculus from the Tipu Maya, offering new insight into both cultural practices and potential health impacts.

Mass spectrometry identified molecular peaks corresponding to nicotine and its degradation products within the calculus samples.  Analysis revealed that over two-thirds of the individuals tested positive for nicotine, supporting the …

‘King Of Infinite Space:’ Confinement And Identity In Hamlet & Contemporary Adaptations, Anna-Laura Houston

Honors Theses

This thesis explores the theme of identity confinement through the lens of Shakespeare's Hamlet and its contemporary adaptations, Fat Ham by James Ijames and Rosencrantz & Guildenstern Are Dead by Tom Stoppard. At the core of this comparative study is Hamlet's paradoxical claim that he could be "a king of infinite space" were it not for his "bad dreams," a statement that encapsulates the tension between internal autonomy and external constraint. The thesis argues that Hamlet's sense of self is shaped-and ultimately fractured-by external demands, including his father's ghostly command for vengeance, the political corruption of Denmark, and an existential …

The Evils Of Illegitimacy: The Construction And Contest Of Kinship-Based Citizenship During Jamaica’S Nationalist Awakening (1930-1945), Ryan Doherty

Honors Theses

Illegitimacy, which refers to kinship units and births outside of the nuclear family, was a major issue in Jamaica. Following the 1938 Uprising, illegitimacy became even larger as an issue as the colonial administration blamed the lower class’s revolt on their kinship units. As for nationalists, the 1938 Uprising was a catalyst for them to rally the lower class to their side, but they, too, were concerned about their illegitimate kinship units. The colonial administration used illegitimacy as a way to push back against nationalists, while nationalists blamed illegitimacy on the colonial administration’s economic exploitation and mismanagement, as well as …

Substrate Complexity Is Not Correlated With Skin Pattern Complexity In Callistoctopus Furvus, Emily Lekas

Honors Theses

Callistoctopus furvus is an understudied, nocturnal octopus that inhabits shallow, subtropical waters in the western Atlantic. This species relies on camouflage to blend in to diverse environments to escape predators. To understand the relationship between substrate and skin patterning in this species, we used second-by-second analysis of video data recorded in the field. We compared frequencies of four substrate types (sand, rock, algae, and seagrass) ranked by contrast across ten skin patterns displayed by C. furvus. Chi-squared analyses showed significant results that the four substrates were unevenly represented in every skin pattern. However, the data did not support our hypothesis …

Dialectal Variations Of Food Terms In The Spanish-Speaking World And Their Causes, Dylan Muccino

Honors Theses

This study explores the dialectal variations of food-related terms across the Spanish-speaking world, emphasizing their multilingual etymological origins. Using etymological dictionaries and sociolinguistic sources, the study categorizes food-related lexical variants into five main root language groups: Arabic/Afro-Asiatic/European, Pre-Columbian Caribbean, Mesoamerican, South American, and unknown or unique origins. The findings represent the persistence of Indigenous influence, the impact of Arabic on Peninsular Spanish, the development of Spanish from Latin, and the role of analogy and adaptation in naming unfamiliar items, illustrating the dynamic and complex relationship between language, culture, and history.

The Effect Of Catalyst Choice On Biodiesel Yield And Quality Using Waste Cooking Oil As A Feedstock, Neka Long

Honors Theses

Biodiesel is one current area of interest as a replacement for traditional diesel fuel. Benefits of biodiesel include that it can be derived from renewable resources, and it possesses properties similar to that of traditional diesel fuel. Biodiesel is often produced through a catalyzed transesterification process, which involves the use of a catalyst to aid in the conversion of triglycerides into alkyl esters. A method called the transesterification double step process (TDSP) was researched and used in this project due to the success seen using this method for the conversion of waste cooking oil to biodiesel. In this project, four …

Christianity And Environmental Stewardship: Locating A New Christian Environmental Ethic In Response To The Climate Crisis, Claire E. Sims

Honors Theses

In Lynn White Jr.’s essay, “The Historical Roots of Our Ecological Crisis,” White argues that Christianity has heavily influenced society’s view of the environment. Rhetoric from Genesis has led people to believe that God intends, and even commands, that humans have dominion over the earth. This narrative provides justification for the abuse of the environment at large, abuse that has been compacted over time to create the climate crisis that we are currently experiencing. Though White’s argument lacks some nuance and somewhat exaggerates Christianity’s role in the environmental crisis, I believe his thesis to be true: Christianity does have a …

Naturam Expellas Furca, Tamen Usque Recurret: Theorizing Approaches To Nature In Antiquity, Ca. 800 Bce 450 Ce, William K. Edwards

Honors Theses

Ancient thinkers reflected on nature and engaged with their abstractions in accordance with many different conceptual frameworks. These frameworks were numerous and diverse, characterized by varying interpretations of nature. Hebrews, Greeks, Romans, and early Christians each adopted approaches to nature; these approaches, conceptual and abstract, were in some ways similar, but also distinct. By analyzing the relevant primary sources, this thesis will investigate the similarities, differences, and interplay between these ancient theoretical frameworks. This thesis will investigate philosophical, theological, historical, ecological, and cultural perspectives on nature. An analysis of these ideas, being aware of their historical contexts, will allow us …

Boxed In: Prose Poetry And Transgender Poetics, Lee Hooker

Honors Theses

Though lived experience is essential to every poet's work, transgender poetry especially must be filtered through the poet's "diet." The manifestation of this experience often results in cross-genre works, such as the prose poem. This thesis consists of a craft essay, in which contemporary queer poets and their genre-bending works are examined, and a creative portion, which emphasizes transgender experience and the prose poem.

Development And Functional Characterization Of Carbon Nanodot-Peptide Conjugates For The Treatment Of Bone Disease, Abigail Ali

Honors Theses

Carbon nanodots (CDs) synthesized from carbon nanopowder under acid oxidative conditions have unique bone-bind properties that could be exploited for theranostic purposes. In the zebrafish vertebrate model system, CDs bind to bone with high affinity and specificity, they don’t appear to bind to other tissues and they do not affect the bone physiology or animal viability. Thus, carbon-derived CDs could be developed for the delivery of pharmacological agents to bones to treat diseases such as osteoporosis. Biologicals such as peptides, proteins and antibodies are a new and exciting class of pharmacological agents that have been successfully used in treating complex …

Shame On Us: The Democratic Costs Of Public Shaming, Elijah Han

Honors Theses

This thesis argues that contemporary public shaming—amplified today by the Internet and universal social membership—is unjustifiable because existing theories ignore its distinctly democratic harms. Defining public shaming as an intentional, collective act that weaponizes social opprobrium, I critique existing consequentialist and deontological defenses, showing they overlook how shaming erodes the conditions for democratic citizenship. Public shaming breeds mistrust, skews who gets to set social norms, chills political participation, radicalizes targets, and obscures what norms actually govern us; these six systemic costs undermine democracy and outweigh any social, economic, or moral benefits except in rare cases where public shaming averts existential …

A Cross-Taxa Comparison Of Avian Telomere Dynamics, Age, And Lifespan, Benjamin Konigsberg

Honors Theses

When eukaryotes replicate cells throughout their life, the end regions of chromosomes naturally degrade as a result of the 5' to 3' directionality of DNA polymerase. There is a point when the chromosome is too damaged to provide normal cellular functions, so the cell will die. Telomeres act as a buffer by providing repetitive sequences of non-coding nucleotides. While telomeres do shorten during replication events, the enzyme telomerase can extend telomeres to prevent senescence. Telomere lengths vary between individuals based on different stressor and stress mitigation. Telomeric rate of change is a metric that can capture telomerase activity by measuring …

Les Femmes Dans Le Monde Médical, Emma Kane

Honors Theses

Cet essai est une investigation du rôle de femmes dans le monde médical avec les anecdotes de femmes des années 1800 a aujourd'hui. On affirme que les femmes avaient été traitées comme des objets de recherche et formation au lieu de patientes et égales. En outre, malgré le progrès de femmes dans le monde médical, elles ne reçoivent toujours pas la même estime que leur homologues homme.

This thesis explores the role of women in the world of medicine through female narratives from the 1800s to present. The essay argues that women have been objectified for research and education purposes …

Adaptation Challenges In Scene-Specific Visual Search For Individuals With Asd, Carmen Ovalle

Honors Theses

This research investigates how individuals with Autism Spectrum Disorder (ASD) process category information and adapt to changing visual environments during search tasks. Drawing on Enhanced Perceptual Functioning and Weak Central Coherence theories, the study examines whether individuals with ASD rely more on detailed, exemplar-based templates compared to neurotypical individuals. Two experiments manipulated category-color associations within real-world scene contexts using match and mismatch conditions to assess visual search efficiency and cognitive flexibility. While no statistically significant group differences were found, a trending effect suggested that neurotypical participants may engage in more scene-based processing. These findings contribute to a growing body of …
