Larval Environments Affect The Implementation Of The Sterile Insect Technique On Aedes Mosquitoes, Katherine G. Evans

Theses and Dissertations

Sterile Insect Technique (SIT) is an effective method for controlling pests and has been increasing in popularity to control Aedes mosquitoes. SIT involves inundating an area with sterilized male mosquitoes to reduce egg hatch and ultimately the number of wild adults. Previous research indicates that enacting mortality early in the larval life of Aedes mosquitoes can result in counter-productive effects, due to reduced competition among developing larvae. I hypothesize that the effectiveness of SIT at reducing adult populations is modified by densitydependent mortality and density-dependent growth among larvae. I performed two field-to-lab studies and developed an individual-based model to test …

Perceptions Of A Hypothetical Student As A Function Of Binge Eating Disorder And Gender, Erin Rose Hennessy

Theses and Dissertations

Stigma toward those with binge eating disorder and a gender bias toward eating disorders can lead to misattribution of symptoms as well as a reduced likelihood of having the diagnosis of eating disorders (Currin, Schmidt, and Waller 2007). Symptoms of binge eating, such as being overweight, have different social meanings than an eating disorder that can lead to being underweight, such as anorexia (Saguy and Gruys 2010). In addition, social support has been previously found to have positive relationships with eating disorder recovery. The purpose of this study was to understand differences in people’s perceptions of targets who are overweight …

How Latine College Students Experience, Maneuver, And Navigate Within The Colonizing Notion Of Smartness, Jasmine Jetton-Gonzales

Theses and Dissertations

This study explores how Latine college students, particularly those who are the first in their family to attend college, navigate and maneuver within the dominating colonizing notion of smartness in academia.

The Tender Flesh: Dwelling In Soft Wounds And Visceral Bodies, Madelyn Irene Turner-Havens

Theses and Dissertations

Within my painting process, I explore bodily interiority and exteriority in relation to the surface of painting, evoking a discomforting sense of corporeal (dis)embodiment, where haunted flesh becomes palpable. Indexing conversations with the body into the painting is a way to understand my body and create an experience of what happens when language fails to capture the complexity of sensation. Painting becomes a mediation with the canvas, a constant discovery of what can give shape to the intangible: how it feels when my skin folds into itself, bodily urges, and the soft texture of fatty tissue.

I let the parts …

“My Pain Was Never More Valuable Than His Potential”: A Rhetorical Thematic Analysis Of Gaslighting Within Sexual Abuse Cases, Makayla Roller

Theses and Dissertations

This thesis examines gaslighting within three prominent sexual abuse cases—Harvey Weinstein, Matt Lauer, and Larry Nassar—uncovered during the #MeToo movement, to better understand the rhetorical function of gaslighting. Using a combination of rhetorical thematic analysis, critical discourse analysis, a feminist lens, and a gaslighting schema, this study identifies the rhetorical tactics, gendered discourse, and power-laden discourse deployed to gaslight victims and the public. I argue that gaslighting must be examined through a rhetorical lens, as discourse is the mechanism through which gaslighting operates, shaping perceptions of truth, credibility, and power. By highlighting how language is weaponized to deny, distort, and …

A New Theater For Age-Old Social Patterns: An Exploratory Study Of Interpersonal Dynamics And The Overlay Of Gender Within Ai Companionship, Miriam Wolff

High Throughput, Solid Sample Analysis With Cone-Based Mass Spectrometric Ionization Sources, Emily J. Wiggins

Theses and Dissertations

The widespread presence of environmental and consumer-product contaminants (e.g. trace metals, opium alkaloids) has underscored the need for rapid, reliable, and high-throughput analytical techniques that are capable of handling complex solid samples. While traditional mass spectrometric (MS) methods tend to have high sensitivity and accuracy, they often require labor-intensive and time-consuming sample preparation steps that limit throughput and field applicability. This thesis investigates the use of 3D-Printed Cone Spray Ionization-Mass Spectrometry (3D-PCSI-MS) as an ambient ionization technique for the direct screening of contaminants from solid matrices, eliminating the need for traditional sample preparation and allowing for real-time analysis.
