Dutiful Wife, Grieving Mother: Examining Medieval Joban Allusion Through A Matricentric Affective Lens, Morgan Lee

Graduate Theses and Dissertations

This thesis uses concepts of matricentrism and affect to examine the legacy of Job and its frequent medieval allusions in stories featuring grieving mothers. It specifically analyzes how, in order to be considered noble, steadfast sufferers, women were expected to relinquish their maternal grief and adopt a stoic affect. This was often to the benefit of or in the direct service of their husbands. The analysis covers three women in particular: Job’s wife (who is examined through the medieval commentary written about her), Prudence from Chaucer’s "Tale of Melibee," and Griselda from Chaucer’s "Clerk’s Tale." This thesis utilizes medieval conduct …

Deciphering Chemomechanical Couplings In Proteins Using Molecular Dynamics And Enhanced Sampling Techniques, Matthew Brownd

The first part of this work focuses on ligand binding in hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, which regulate rhythmic electrical activity in the heart …

Wildflower Season: A Semi-Somnolescent Retrospective, Connor Johnson

Graduate Theses and Dissertations

I came to graduate school under the impression that I would be working on my own. I believed the process of playwriting to be an individualistic pursuit, where my plays came from my mind and my mind alone. Instead, through the process of writing my thesis play, Wildflower Season, and its subsequent production as part of the ArkType New Play Festival, I discovered that writing a play was a collective endeavor, and that one of the great pleasures the theatre has to offer is creating it with a group of other people.

Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri

Graduate Theses and Dissertations

This thesis examines how Arabic and English literary and intellectual traditions responded to the Black Death as a shared yet differently articulated experience of collective trauma. Drawing on trauma theory, particularly the work of Cathy Caruth and Dominick LaCapra, it analyzes how plague narratives function as cultural mechanisms for processing mass suffering. Through a comparative study of Arabic historiographical, theological, medical, and poetic texts alongside English allegorical, mystical, autobiographical, and satirical writings, this project argues that both traditions developed distinct narrative strategies to render the trauma of plague intelligible. Arabic plague literature, represented by figures such as Ibn Khaldūn, Ibn …

Clear-Air Turbulence Climatology And Trends, Liam Rodgers, Mark Sinclair

Publications

Clear‑air turbulence (CAT) is a major aviation hazard that occurs near airline cruising altitudes in both cloud and cloud‑free environments. Its lack of a distinct visual signature makes detection and avoidance difficult. CAT is associated with wind shear near jet streams, gravity waves, and Kelvin–Helmholtz instability and may be further enhanced by climate change. This study examines the climatology, spatial distribution, seasonal variability, and trends of CAT over the contiguous United States.

Pilot Reports (PIREPs) from 2001–2025 between 100 and 400 hPa are analyzed alongside jet stream, shear, and stability diagnostics derived from NCEP–NCAR Reanalysis data. Proxies such as inverse …

An Analysis Of The Rapid Intensification Of Hurricane Milton, Ayden Rodriguez, Mark Sinclair

Publications

Hurricane Milton (October 2024) provides a compelling case study of a multiscale pathway to rapid intensification (RI), highlighting the alignment of synoptic preconditioning, favorable environmental conditions, and rapid inner-core structural evolution. The storm originated from the interaction of multiple tropical waves embedded within a low-level trough associated with the Central American Gyre, which enhanced low-level vorticity and moisture convergence prior to development. Upon entering the Gulf of Mexico, Milton encountered an environment characterized by anomalously warm sea surface temperatures, high ocean heat content, and weak vertical wind shear, enabling steady intensification and the onset of explosive RI that exceeded conventional …

The Reliance On Children In Atomic Bomb Literature, Chenyeng Vang

English Undergraduate Honors Theses

This paper explores the conventions of children’s literature, or what children embody in literature, and how it functions within atomic bomb literature in three ways: filling the gap of the unreliability of language, pushing past binaries through its queerness, and universalizing messages of peace to focus on a broad vision of a better future. Analysis involves atomic bomb literature written within the first five decades of the bombings, from 1945 to 1995. This research additionally seeks to answer the question: why children’s stories? This paper concludes that the dependence on children within atomic bomb literature hinges upon constructions of children …

Survey Of Medieval Literature On Maternal Mortality, Postpartum Care, And Birth Trauma In Relation To The Crisis In Arkansas, Paige Q. Thompson

English Undergraduate Honors Theses

When the general public thinks of childbirth in the Middle Ages, they think of death and danger. However, Arkansas has the highest maternal mortality rate in the entire United States, and many of those deaths are preventable. There have been previous analyses on different medieval texts as well as research into modern Arkansas, but none have made a direct connection between the two subjects. By analyzing medieval literature to understand cultural norms surrounding childbirth and postpartum care, patterns can be traced to modern Arkansas, where needless deaths are still prevalent. Ultimately, medieval texts demonstrate cultural attitudes surrounding blame toward women …

Integrating Doulas Into The Medical Team, Alyssa Shaw

Anthropology

This thesis explores the potential integration of doulas into the obstetric medical team, defining birth as a cultural and social experience as well as a physiological process. Drawing on anthropological literature and historical accounts, I examine the shift from social, woman-centered childbirth practices to the medicalized model that occurs in modern American obstetrics. While this transformation has improved maternal and infant mortality rates, it has also caused a loss of continuous emotional and social support for laboring mothers, as well as a shift in autonomy from the birthing person to medical professionals. To investigate how doulas may help bridge this …

Microplastics And Generational Harm, Sara Najafi

Anthropology

Microplastics are persistent environmental contaminants increasingly detected in ecosystems and the human body, raising concerns about their effects on health and future generations. This paper examines the environmental pathways, biological mechanisms, and reproductive consequences of microplastic exposure, with particular attention to female reproductive health and fetal development. Current evidence indicates that microplastics can contribute to oxidative stress, inflammation, endocrine disruption, DNA damage, and cellular dysfunction, while also accumulating in reproductive tissues, follicular fluid, placental tissue, and breast milk. These exposures may impair ovarian function, fetal development, and long-term health outcomes. The paper also considers environmental inequalities that may increase exposure …
