The Role Of Exotic Plants In The Diet Of Black-And-White Colobus Monkeys (Colobus Guereza) In Kibale National Park, Uganda, Michelle Gaykov

Theses and Dissertations

Exotic plants have both positive and negative impacts on their environment. They may act as additional food sources for the local fauna or as competition for local flora or leading to changes within a landscape or ecosystem. To considere the role of exotics in primate diet, this study focused on the dietary role of exotic plant species in the diet of a leaf-eating foregut fermenting monkey, the black-and-white colobus monkeys (Colobus guereza) in Kibale National Park, Uganda. Int this study, I followed individuals in two groups of black-and-white colobus monkeys for 21 days recording their food intake (0700-1900). I also …

The Decadent Bible: Biblical Intertextuality In Flaubert’S Herodias And Wilde’S Salome, Shoshana Mintz

Theses and Dissertations

This paper argues that Gustave Flaubert’s Hérodias and Oscar Wilde’s Salomé incorporate biblical intertextuality throughout their work as a means to showcase Decadent technique and themes. Both authors weave direct quotations from biblical sources such as the Gospels of Matthew and Mark, Isaiah, Ezekiel, Revelation, and Acts into their texts, layering biblical passages with themes of excess, eroticism, and decay central to the Decadent movement. Drawing on Julia Kristeva’s theory of intertextuality, I show how these biblical fragments intersect with narrative voice to destabilize meaning and form a unique, new work of writing that intertwines their own words with biblical …

Capturing The Spirit Of Childhood: An Analysis Of Robert Henri’S Portraits Of Children, Alex C. Maccaro

Theses and Dissertations

Robert Henri (1865-1929) is perhaps best known as the prominent leader of the turn-of-the century American movement The Eight, commonly known as “the Ashcan School,” and as a leading teacher in the United States during the early twentieth century. However, his artistic output as a portrait painter, particularly of children, is also significant. Beginning in 1904 and throughout his career as an artist, Henri painted hundreds of images of children in the various foreign or remote locales to which he traveled, often depicting the same subject in multiple instances. These portraits range from the roughly painted, rosy-cheeked Dutch youth of …

Anticancer Efficacy Of Methyl-Cantharidimide (Mca) In Liver Cancer, Yidong Li

Theses and Dissertations

Cancer is still one of the major public health challenges worldwide to the present day. Multi-drug resistance (MDR) that occurs in cancer chemotherapies is a non-negligible cause of cancer treatment failure and tumor recurrence. Overexpression of ATP-binding cassette (ABC) transporters is one of the most frequent mechanisms of MDR occurrence. Therefore, the establishment of a chemotherapy agent whose anticancer efficacy would not be affected by the overexpression of ABC transporters is in demand. Methyl-cantharidimide (MCA), a cantharidin (CTD) analog, has been approved in China for clinical liver cancer treatment. This study revealed that MCA was efficacious in the ABCB1-, ABCG2-mediated …

Evaluation Of The Mechanism Of Cell Death After Exposure To Amorphous Silicon Dioxide Nanoparticles In Rat Pleural Mesothelial Cells And Golden Syrian Hamsters, Rachel P. Renda

Theses and Dissertations

Amorphous Silicon Dioxide Nanoparticles (SiO2 NPs) are widely used in the industrial processes, chemical, and cosmetics industries. Amorphous SiO2 NPs are abundant in the earth’s crust and can be released into the air through industrial and manufacturing activities. Such particles are overlooked and not as commonly studied when compared to their crystalline counterpart. Amorphous SiO2 NPs are pulmonary toxicants; however, the mechanism of toxicity is uncertain. In the current study, toxicity was assessed using both in vitro and in vivo systems to understand a possible mechanism of cell death. Rat Pleural Mesothelial Cells (RPMCs) were exposed to 50-800 μg/ml SiO2 …

Utilizing A Genetically Diverse Species To Investigate Gene-Drug Interactions And Drug Efficacy, Jerry Nawongbay Gbarlea

Theses and Dissertations

Gene-drug interactions are fundamental to understanding variability in drug response and therapeutic efficacy. In this project, we leverage the natural genetic divergence between ecotype morphs of the blind Mexican cavefish (Astyanax mexicanus) to investigate differential responses to neuroactive compounds—specifically, the convulsant pentylenetetrazol (PTZ) and the anxiolytic Buspirone Hydrochloride. Astyanax Mexicanus is a tetra species consisting of both surface-dwelling (ancestral) and cave-dwelling (mutant) populations that have highly variable genetic backgrounds. Independently evolved populations of cavefish exhibit a suite of convergent traits that can be functionally interrogated to discover new genetic functions and interactions. These attributes make A. mexicanus an ideal model …

In The Wake Of The Anthropocene: The Ecopoetics Of Shakespearean Film Adaptations, Ioannis Garganourakis

Theses and Dissertations

This dissertation explores how Shakespeare’s plays and their film adaptations reflect and respond to the conditions of the Anthropocene, arguing that both forms of art can foster an environmental ethic attuned to the interconnectedness of human and nonhuman worlds. It proposes that the Anthropocene did not begin with industrialization but rather intensified a much older pattern of human ecological intervention, a process that becomes increasingly visible from the early modern period to the twentieth century. By situating Shakespeare within this expanded temporal framework, this dissertation reveals how his works anticipate and interrogate the very assumptions about anthropocentrism that underpin modern …

Biogothic: New Directions In The Haunted Spaces Of Nineteenth Century Gothic Fiction, Jessica Mintzes

Theses and Dissertations

The BioGothic is a set of biological metaphors in nineteenth century Gothic fiction that anticipates our contemporary understanding of what we now think of as biological processes. The BioGothic system in the novel captures the site of connection and interaction between the body and the interior spaces it inhabits. The Gothic genre, from its inception, shifts the focus onto interior spaces and the ways in which architectural spaces and the Gothic body interact with one another. This demonstrates, in part, how physical space and biological matter are not only capable of becoming integrated with each other, but also maintain the …

Timbral Effects Of 3d Printing Brass Wind Musical Instruments: A Comparison Between Traditional And 3d Printed Construction, Cole K. Zelman

Theses and Dissertations

This study explores the timbral effects that manufacturing wind instruments from thermoplastics (via 3D printing) has in comparison to traditionally made instruments. The project mainly focuses on the individual properties of different thermoplastics in comparison to traditional materials like brass. The instrument tested is a C bugle for a simple example of a brass wind instrument and is compared directly against the traditional brass construction. Results employ spectral centroid, spectrograms, and professional subjective analysis to compare the different thermoplastic test samples to the control brass bugle.

Type Ii Diabetes Treatment Comparison Via Compartment Modeling, Abigail M. Collins

Theses and Dissertations

Type II diabetes mellitus affects one in ten adults worldwide, yet the effects of treatment type and adherence level on developing complications and quality of life have not been well characterized at the population level, and mathematical modeling offers a structured way to examine these dynamics. This thesis adapts the Boutayeb et al. (2004) model to incorporate dynamic treatment types and levels of adherence, producing nine scenarios in which complication development rate and complication recovery rate differed, to compare peak complications and quality of life across treatment and adherence conditions. Using a system of ordinary differential equations and compartment modeling, …

Thinking Machines: Cybernetics, Artificial Intelligence, And Technological Anxiety In The American Cold War, Erin Mae Wilcox

Theses and Dissertations

Following the Second World War, cybernetics emerged as a cross-disciplinary study in philosophy, neurophysiology, electrical engineering, and mathematics. Cyberneticists proposed the formal study of the man-machine analogy; that is, to equate biological structures to a complex mechanical system. Drawing from this analogy, cyberneticists used programmable digital computers to emulate the functions of the human brain. The study of artificial intelligence emerged within this cybernetic discourse in the early 1950s; yet, by the mid-1960s, the two disciplines suffered a methodological fracture. Drawing from a tradition generated by this fracture, historians have traditionally examined cybernetics and artificial intelligence in isolation from one …

Social Media, Masculine Body Ideals, And The Drive For Muscularity: A Serial Mediation Model Across Sexual Identities, Sean P. Mcdaniel

Theses and Dissertations

Body image concerns among men are increasingly prevalent yet remain understudied compared to women’s experiences. Drawing on objectification theory, the present study examines the relationship between social media influence and men’s drive for muscularity through a serial mediation model. Specifically, the present study investigates whether the internalization of masculine body ideals and engagement in body surveillance behaviors mediate the link between social media influence and the drive for muscularity. Furthermore, the present study model attempts to explore how these processes differ across sexual identities, given evidence that sexual minority men face distinct sociocultural pressures regarding appearance. Adult male-identifying social media …

Cover Crop Effects On Soil Porewater Nutrients And Hydrothermal Properties, Md Mahadi Hasan

Theses and Dissertations

Adoption of winter cover crops in the U.S. Midwest may reduce nitrogen (N) and phosphorus (P) leaching from soils, potentially shrinking the hypoxic zone by limiting nutrient runoff into the Gulf of Mexico. To evaluate the impact of selected winter cover crops on soil porewater N and P concentration, a field study was conducted at the Illinois State University Research Farm (ISURF) and the Western Illinois University Research Farm (WIURF). The experimental design was a block experiment with four replications.  Cover crop treatments included a winter fallow, wild pennycress (WPC), golden pennycress (GPC), cereal rye (CR), annual ryegrass (AR), and …

Secret-Keeping Experiences Of Young Adults, Jace C. Griffith

Theses and Dissertations

In 2020, researchers Frijns et al. called for a new wave of secret-keeping research which prioritized the person-centric experience of youth keeping secrets. This study added to that collection by comparing two kinds of secret-keeping which are not compared in existing research: secrets which are related to abuse, and secrets which are not. Researchers in the field of child welfare study only abuse-related secret-keeping, almost always qualitatively. Alternatively, researchers of non-abuse secret-keeping or general secret-keeping collect almost entirely quantitative data, absent of the personal experience of secret-keeping.

Through an online survey, 205 undergraduate students were asked to reflect on an …

Creating "An Exemplar Of A Better World": A Dialogic Analysis Of Academic Freedom Surrounding Columbia University Activism From 2023-2025, Ellanore Foltz

Theses and Dissertations

From October of 2023 to August 2025, the community at Columbia University engaged in a series of debates regarding the meaning of academic freedom. Academic freedom, first institutionalized in the United States during the first world war, has shifted over the decades as the purpose of higher education and the threats to higher education changed. In recent years, campus protests regarding Israel and Palestine have sparked new debates about academic freedom that reflect ongoing and sometimes fundamental disagreements about higher education. This study utilizes Relational Dialectics Theory (RDT; Baxter, 2011) to explore the interplay between different discourses of academic freedom …

Reconciliation, Draper Matthews

Theses and Dissertations

This thesis exhibition, Reconciliation, examines how memory, loss, and lived experience shape personal identity over time. Through sculptural works composed of cast, blown, and hot-sculpted glass combined with mixed media, the exhibition explores the pressures that life events place upon individuals and the ways those pressures persist, transform, and become integrated into the self. The work considers identity not as a fixed state but as a continual process of negotiation between past experiences, present circumstances, and future possibilities.

Central to the project is the material analogy between glass and human experience. Glass, a material formed under extreme heat and pressure …

The Effects Of A Work-Strengths Affirmation Intervention On Death Anxiety: Meaning And Self-Esteem As Mediators, Begüm Orhan

Theses and Dissertations

Death anxiety is a transdiagnostic construct and a universally experienced existential fear that has been linked to a wide range of psychological difficulties, including anxiety, depression, and impaired well-being. Despite its widespread impact, empirical research on targeted interventions for death anxiety remains limited. The present study aimed to address this gap by developing and evaluating an online, single-session, theory-based (i.e., Terror Management Theory, positive psychology) intervention focused on affirming personal strengths in the context of one's work. The intervention was designed to target work-strengths (i.e., leadership, adaptability)—an intersection of positive and vocational psychology.

College students from a large Midwestern university …
