Using archival data from the Correlates of Adversity and Temperament in Childhood (CATCH) dataset, responses from 230 participants were analyzed. Mediation analyses revealed that perceived social support mediates the relationship between ACEs and both anxiety and depression. Moderated mediation analyses further indicated that …


Exploring Young Adults’ Implicit Theories Of Emotion And Emotion Dysregulation On Parental Emotion Socialization And Internalizing Symptomology, Daryl Parungao May 2025

Exploring Young Adults’ Implicit Theories Of Emotion And Emotion Dysregulation On Parental Emotion Socialization And Internalizing Symptomology, Daryl Parungao

Electronic Theses and Dissertations

Research regarding emotion socialization suggests parents’ responses towards their children’s negative emotions, which may be characterized as either emotion dismissive or emotion coaching behaviors, are associated with children’s well-being into adulthood. A heuristic model of emotion socialization suggests that child-level factors related to emotion processing may moderate this association (Eisenberg, 1998), which warrants further examination when considering relevant risk factors for mental health disorders such as anxiety and depression. This dissertation explored how parent emotion socialization responses interact with young adults’ beliefs about the controllability of emotions and their difficulties with emotion regulation with regard to their impact on young …

Application Of Deep Learning On Gage R&R For Anomaly Detection, Oluwatope Richard Ojo May 2025

Application Of Deep Learning On Gage R&R For Anomaly Detection, Oluwatope Richard Ojo

Electronic Theses and Dissertations

This thesis explores the application of deep learning techniques, specifically autoencoder based models, to enhance anomaly detection within Gage Repeatability and Reproducibility (Gage R&R) studies—an essential component of Measurement System Analysis (MSA) in quality engineering. Traditional Gage R&R methodologies, while effective for linear and low-dimensional data, exhibit limitations in detecting subtle, nonlinear variations in complex measurement systems. To address this challenge, an unsupervised autoencoder was developed and trained on a synthetically generated dataset comprising 2,500 voltage measurements (5V and 33V) derived using Generative Adversarial Networks (GANs) based on real-world manufacturing data measurements.

The proposed autoencoder model achieved a 95th percentile-based …


The Food Truck: A Multi-Product Newsvendor With Trans-Shipment Cost, Samuel Ajibola May 2025

The Food Truck: A Multi-Product Newsvendor With Trans-Shipment Cost, Samuel Ajibola

Electronic Theses and Dissertations

The Newsvendor Problem is a key model in supply chain management that focuses on determining the optimal order quantity to minimize costs under uncertain demand. This thesis introduces the Food Truck Problem, an extension of the Newsvendor model that incorporates nonlinear transshipment costs for inventory transportation. In this context, a Food Truck must determine the optimal stock levels for multiple products while minimizing costs related to stock shortages, excess inventory, and transportation. Unlike traditional Newsvendor models, our approach explicitly considers a quadratic transshipment cost, which necessitates the use of Lagrangian duality and Karush-Kuhn-Tucker (KKT) conditions for analysis. Moreover, we apply …

Performative Masculinity In Ducal Literature In Florence (1520-1580), Matthew T. Perkins May 2025

Performative Masculinity In Ducal Literature In Florence (1520-1580), Matthew T. Perkins

Electronic Theses and Dissertations

Ducal literature of sixteenth-century Florence illuminates the performative nature of gender and sexuality, especially in regard to masculinity. The impetus of this study is Benvenuto Cellini’s autobiography, My Life. While contemporary historiographical studies examine Cellini’s work for its overt misogyny and violence, this work argues that the performative nature of gender, through interdisciplinarity and contextual analysis, offers a highly complex view of masculinity. Cellini’s autobiography directly relates to Giorgio Vasari’s The Lives of the Most Excellent Painters, Sculptors, and Architects. Vasari’s accounts of Michelangelo di Lodovico Buonarroti Simoni and Giovanni Antonio Bazzi, called Il Sodoma, emphasize the importance of fashioned …

Diversity In Beauty Brand Marketing On Instagram: The Case Of Fenty Beauty, Julia K. Narh

Electronic Theses and Dissertations

Diversity in beauty brand marketing is increasingly important as platforms like Instagram shape consumer perceptions. This study analyzes how Fenty Beauty, MAC Cosmetics, and L’Oréal represent diversity, particularly skin tone, in their Instagram content, using source credibility theory and social identity theory. A content analysis was conducted to evaluate how visual elements relate to engagement, measured by likes, comments, and shares. Findings show that Fenty Beauty features more dark-skinned models than its competitors. However, posts with darker-skinned models do not receive higher engagement. Instead, factors like model attractiveness and hair type, especially curly hair, drive interaction. Although Fenty’s posts generally …


Inferring Feeding Biology In Extinct Shrews (Soricidae: Mammalia): Application Of A Linear Morphometric Approach, Derek J. Den Ouden May 2025

Inferring Feeding Biology In Extinct Shrews (Soricidae: Mammalia): Application Of A Linear Morphometric Approach, Derek J. Den Ouden

Electronic Theses and Dissertations

Linear morphometrics have been used extensively to infer the ecology of fossil organisms, but shrews have not yet been thoroughly explored using this technique. Often considered to have a homogenous insectivorous diet, direct dietary observation suggests shrew dietary diversity is substantial. Diversity of this nature is well established to have influenced skull morphology in other mammal clades, so similar patterns are hypothesized to be detectable in shrews. To test this, I examined the link between known diet and morphological disparity in extant shrews using linear morphometrics and then utilized that framework to infer the dietary ecology of several fossil taxa. …
