“This Generation Of Women Is Finished”: Misogyny As Social Bonding On Social Media And Patriarchal Constructions Of Femininity, Emma Mierzejewski Jan 2025

“This Generation Of Women Is Finished”: Misogyny As Social Bonding On Social Media And Patriarchal Constructions Of Femininity, Emma Mierzejewski

Electronic Theses and Dissertations

This thesis explores online discourse between users on social media platforms, specifically Instagram, in an effort to better understand the patriarchal influence on American social culture. Users on the platform regularly write off misogynistic comments as simply “dark humor” or an extreme expression of one’s “freedom of speech.” At the same time, supportive comments are also influenced by those same misogynistic expectations. I argue that misogynistic thinking in comments and a willingness to uphold them for social bonding provides deeper insights into our society’s attitudes towards women, their roles, and conceptions of femininity in general. I conducted a content analysis …

Making Hot Chocolate: Connecting Hypersexuality And Violence Against Black American Women In 20th And 21st Century Literature, Ashlan Stewart

Electronic Theses and Dissertations

African American literature in the early 20th and 21st centuries have been employed as a method of protest against the deleterious stereotyping of Ebonic (read: Black American) people in the United States, addressing and challenging the monolithic notions that define Ebonic people in life and media. In the process of expressing these protests, challengers to racist social norms utilize the Ebonic female body and image for the benefit of their personal interests through a combination of hypersexuality and violence. This thesis addresses the lack of accountability in these political lenses and assesses the ways in which authors objectify and abuse …


Influences Of Dynamic And Static Retrieval Cues On Memory Accuracy And Reaction Times, Megan S. Smithwick Jan 2025

Influences Of Dynamic And Static Retrieval Cues On Memory Accuracy And Reaction Times, Megan S. Smithwick

Electronic Theses and Dissertations

Prior research on recognition memory has utilized static stimuli (e.g., words) to evaluate the time course of retrieval for different types of information —familiarity-based item memory and recollection-based associative memory. The present study investigated this time course in dynamic stimuli. Participants (N = 188) viewed videos at encoding, depicting 64 actors performing unique actions. At test, participants viewed either videos or images presented for short (733 ms) or long durations (1,466 ms). The test item types included old (same actor and action pairing), conjunction (novel pairing of familiar actor and action), new actor (unfamiliar actor, familiar action), and new action …


The Observer & The Observed, Azarakhsh Shafieikadkani Jan 2025

The Observer & The Observed, Azarakhsh Shafieikadkani

Examining Relationships Between Sediment Nutrients And Halodule Wrightii In The Southern Indian River Lagoon, Sarah Newton Jan 2025

Examining Relationships Between Sediment Nutrients And Halodule Wrightii In The Southern Indian River Lagoon, Sarah Newton

Electronic Theses and Dissertations

In the Indian River Lagoon (IRL), FL, seagrasses have declined 58% since 2009, largely due to eutrophication. Efforts to improve IRL water quality are ongoing, but there has been a lag in seagrass recovery, with Halodule wrightii being the focus of restoration efforts. Because seagrasses uptake nutrients through their rhizomes and blades, this lag may be associated with undocumented pore water nutrient pollution. Thus, deciphering relationships between sediment nutrients and H. wrightii is necessary. In this study, sampling at nine sites in the southern IRL (SIRL) was conducted in spring and summer 2024 during which H. wrightii tissue, sediment, and …


The Quiet Gnosticism Of Samuel Beckett’S Endgame, Andrew Dean Chapman Jan 2025

The Quiet Gnosticism Of Samuel Beckett’S Endgame, Andrew Dean Chapman

Electronic Theses and Dissertations

This thesis draws on and extends previous Gnostic readings of Samuel Beckett’s fiction which has located the figure of the demiurge mostly in the background and finds through close reading that in Endgame the demiurge takes the foreground.

This thesis proposes that Endgame’s gnosticism goes further than recreating gnostic themes and tropes. Rather, Endgame’s gnosticism fuses the gnostic laughter of the gnostic Christ, Schopenhauerian tragedy, and Quietist paradoxes to create a system of progressive enlightenment which culminates in a revelation evidenced by a laugh that, in Beckett’s Watt, is called the mirthless laugh. This laugh, I propose, is the laugher’s …

Movie Genre Classification Using Script Texts, Michael Roman Cuomo Jan 2025

Movie Genre Classification Using Script Texts, Michael Roman Cuomo

Electronic Theses and Dissertations

Genres are used to classify movies so that they can be grouped with others that have similar themes and structures. These classifications are categories created by humans. In the process of creating a movie, a script is often the first creation to write and share ideas about a topic. The script contains large amounts of text that is used to describe the dialog, setting and direction of the film. Although the script contains important information for the film, the amount of text can present a challenge for machine learning algorithms. Often in studies on film classification, if text is used, …

The Pre-Polarization And Concentration Of Cells Near Micro-Electrodes Using Ac Electric Fields Enhances The Electrical Cell Lysis In A Sessile Drop, Kishor Kaphle, Dharmakeerthi Nawarathna Jan 2025

The Pre-Polarization And Concentration Of Cells Near Micro-Electrodes Using Ac Electric Fields Enhances The Electrical Cell Lysis In A Sessile Drop, Kishor Kaphle, Dharmakeerthi Nawarathna

Electrical & Computer Engineering Faculty Publications

Cell lysis is the starting step of many biomedical assays. Electric field-based cell lysis is widely used in many applications, including point-of-care (POC) applications, because it provides an easy one-step solution. Many electric field-based lysis methods utilize micro-electrodes to apply short electric pulses across cells. Unfortunately, these cell lysis devices produce relatively low cell lysis efficiency as electric fields do not reach a significant portion of cells in the sample. Additionally, the utility of syringe pumps for flow cells in and out of the microfluidics channel causes cell loss and low throughput cell lysis. To address these critical issues, we …
