Through the lens of the Hallyu (The Korean Wave), this study analyzes how K-drama’s navigate an ambiguous cultural space which simultaneously resists Western media dominance while appropriating global forms including platform-based distribution, tailoring original content to …

Rise Above!! Second-Wave Post Punk/ Hardcore In Orange County, 1977-1983, Jessie Zepeda

Electronic Theses, Projects, and Dissertations

Post-punk and Hardcore played a pivotal role in creating a youth identity in Orange County that created a stark contrast to the more recognized Republican image of O.C. during the late 1970s and early 1980s. While historians view this era of California for its Republican ties with former presidents such as Ronald Reagan and Richard Nixon, we overlook the much more underground, yet important, identity created by many of the adolescents and young adults during this time. Though it is essential to recognize these Republican ties as they play a key role in understanding political dynamics and cultural studies that …

A Note On Saint Vincent’S Armchair: Toward Resolving A Mystery?, John E. Rybolt C.M.

Vincentian Studies

An armchair said to have been used by Vincent de Paul may shed some light on his early career. The chair has rods in its arms to support a board between them to serve as a desk. It was donated to the Berceau in 2010 by a family from Buzet-sur-Tarn, accompanied by a note that says that Vincent used this chair during summers from about 1598 until 1604 while he tutored the sons of local nobility and other students in the area. We still don’t know when or why he came there, the level of his instruction, how long he …

Vincent De Paul And The Reform Of The Clergy, John E. Rybolt C.M.

Vincentian Studies

Vincent de Paul was an important reformer of the French Church, which faced several problems with its clergy. Liturgical practices were not standardized, and some priests lived corrupt lives. Because they received stipends for masses, they often celebrated them for that reason rather than out of piety. They tried to acquire several benefices (church offices) and dioceses at the same time to profit from them all, although this was against canon law, and these were sometimes essentially sold or hoarded by noble families. Church titles and their accompanying incomes were also auctioned off by monasteries, and these, too, were purchased …

The Civic Oath At Saint-Lazare, 1790, John E. Rybolt C.M.

Vincentian Studies

This study presents the French text, English translation, historical context, and a brief analysis of the speech given at Saint-Lazare on the civic oath-taking in support of the 1790 revolutionary government in France, which every adult citizen had to do publicly.

Civic engagement can be broadly defined as the practice of service (volunteering or informal helping), advocacy, and political participation (voting). Older adults are a large and growing population that frequently engages in these civic activities.

In 2022, the Bureau of Labor Statistics reported that approximately one quarter of the 11 million daily volunteers in the U.S. were age 65 and older. Between 2018 and 2021, there was a 10% increase in volunteer hours filled by individuals over age 65. Research shows this trend will be mutually beneficial, improving the quality of life for older adults who are, in turn, positively …

Weaponized Deepfakes: A Low-Resourced Attacker Threat Assessment, Joshua David Labelle

Master's Theses and Capstones

The democratization of Artificial Intelligence and Machine Learning (AI/ML) tools, combined with the short-form nature of modern media consumption, has created a ripe landscape for generating and weaponizing synthetic media. The availability of pre-trained, open-source generative models enables would-be attackers, who lack funding and enterprise-grade hardware, to conduct convincing information-based attacks that harm, manipulate, and deceive. This thesis aims to model this threat actor using an open-source deepfake generation pipeline that requires minimal computational resources and is capable of producing deepfakes in the audio, image, and video domains. This model is then used to identify, measure, and evaluate the capabilities …

Reading Ability Underlies The Composite Effect For Arabic Words, Rayan Kouzy, Zahra Hussain

School of Psychology

The composite effect, originally demonstrated for faces, has recently been shown to suggest holistic processing of words. The effect is associated with reading fluency in Latin script, but not in nonalphabetic Chinese script, suggesting that script properties influence its relationship with reading expertise. We measured the composite effect for Arabic, a visually complex alphabetic script that offers a useful contrast against Latin and Chinese. Arabic-English bilinguals (N = 24), and English-only readers (N = 22) completed a composite effect task, in which they judged whether the left or right halves of word pairs were the same or different. The unattended …

Investigating The Role Of Motivation On The Effectiveness Of Computerized Cognitive Training Among At-Risk Youth, Emely N. Lugo

Electronic Theses, Projects, and Dissertations

Student motivation plays a central role in academic success, influencing persistence, engagement, and performance across grade levels. Within situated expectancy-value theory (SEVT), motivation is shaped by students’ beliefs about their ability to succeed (expectancy), the importance or usefulness they assign to a task (value), the perceived effort or trade-offs involved (cost), and the situational context in which learning occurs. Although the link between motivation and academic performance is well known, there is limited research on how motivational factors, like those proposed by SEVT, influence the extent of cognitive gains from school-based cognitive interventions designed to improve abilities related to academic …
