Beyond Symptoms: Examining Perinatal Mental Health Care Among Black, Indigenous And People Of Color With Polyendocrine Metabolic Ovarian Syndrome, Vinaya Thomas

Electronic Theses and Dissertations

Perinatal mood and anxiety disorders (PMADs) are as a public health concern in the United States. Individuals from minoritized racial/ethnic groups face a significantly elevated risk of maternal morbidity, mortality, mental health disorders, and associated adverse outcomes. Emerging studies also reveal a higher likelihood of experiencing perinatal mental health concerns in individuals with polycystic ovarian syndrome (PCOS), currently known as polyendocrine metabolic ovarian syndrome (PMOS). People who identify as Black, Indigenous, or a person of color (BIPOC) face unique healthcare challenges given the added structural and social burdens. This online survey study aimed to 1) understand the relationship between PMOS …


Perceptions, Attitudes, And Experiences Of Persons Who Work In Forensic Mental Health Systems, Abigail Wiser Dec 2026

Perceptions, Attitudes, And Experiences Of Persons Who Work In Forensic Mental Health Systems, Abigail Wiser

Electronic Theses and Dissertations

The forensic mental health system serves clients with dual needs —serious mental health concerns like psychosis and suicidality, and management of risk. Experiences and perceptions of professional and direct care staff may impact daily and therapeutic interactions and client success. These experiences may be marked by stigma, such as beliefs about what led to hospitalization, treatability of mental health concerns, and intentionality of behavior. Understanding this stigma, as well as the role of vicarious trauma, workplace burnout, and other relevant individual factors, may help us understand staff experiences and guide training, thus improving client care. 146 staff members across three …

"Help Me Live It The Way You Do": Grounding Singaporean Responses To The Rorschach Situation, Casey Y. Lee Aug 2026

"Help Me Live It The Way You Do": Grounding Singaporean Responses To The Rorschach Situation, Casey Y. Lee

Electronic Theses and Dissertations

Contemporary research on the Rorschach and culture is striking for the latter’s disappearance as a variable of significance (Meyer et al., 2015; Meyer et al., 2007; Mihura et al., 2013; Viglione & Hilsenroth, 2001). This erasure is chronicled and reproduced in the narratives of universal objectivity, of extensive international meta-analyses, of replications, of standardized norms (Ritzler, 2004; Smith et al., 2018; Smith et al., 2020; Weiner, 2004). A different story emerges, however, when we ask, how has culture disappeared? The proposed study is a multimethod qualitative analysis of Singaporean responses to the Rorschach, aimed at generating sensitive yet critical discourses …


The Person As Foundation Of Responsibility: The Insufficiency Of Rights-Based Human Development Approaches, Jaclyn Berg Aug 2026

The Person As Foundation Of Responsibility: The Insufficiency Of Rights-Based Human Development Approaches, Jaclyn Berg

Electronic Theses and Dissertations

Building on the plethora of research that demonstrates the way rights language has been more useful for those with wealth and power to further expand capitalist markets, this text extends that criticism to human development programs and institutions. While they claim to be directed towards addressing global issues of poverty and hunger as well as climate crises, they continue to treat the symptoms without accurately diagnosing the disease. Approaches to development that rely on rights without questioning the way rights have been influenced by neoliberal capitalists or without questioning the capitalist global economic system will never be able to achieve …


Impact Of Taped Problems Intervention Modification On Children With Deafness, Clyniece Hodge Aug 2026

Impact Of Taped Problems Intervention Modification On Children With Deafness, Clyniece Hodge

Electronic Theses and Dissertations

Children with hearing loss are at an increased risk of experiencing setbacks in various areas of life, including academic performance and employment opportunities. Academically, they are likely to experience poor academic achievement in reading, as well as in mathematics (ASHA, 2013). In comparison to gifted hearing students and average-ability hearing students, students with hearing loss are at a higher risk of low mathematics performance (Hassan & Mohammed, 2019). Despite these known challenges and risk factors, limited research has been conducted to identify effective intervention strategies for improving mathematical outcomes among this population. As such, this study aimed to evaluate the …


Dialogic Communication Ethics As A Hopeful Response To Artificial Intelligence, Kristen Haldeman Aug 2026

Dialogic Communication Ethics As A Hopeful Response To Artificial Intelligence, Kristen Haldeman

Electronic Theses and Dissertations

Within the past five years, a new technology has dominated modern culture: artificial intelligence. With a multiplicity of ways to respond to this new environment, this dissertation situates a response to artificial intelligence by combining the media ecology and communication ethics perspectives. Media ecology explores historical roots and biases of technology to learn about their influence of humanity. A dialogic communication ethics seeks to find an opening for hope to emerge. Hope, grounded in the works of Jacques Ellul and the Christian tradition, offers a new rhetorical perspective by shifting focus away from technology and to our neighbor.

The Purpose Of Integration Beyond Expression: Emerging Human Patterns And Possible Selves In A Computational Model Of Self-Reflection, Lore Olson Aug 2026

The Purpose Of Integration Beyond Expression: Emerging Human Patterns And Possible Selves In A Computational Model Of Self-Reflection, Lore Olson

Electronic Theses and Dissertations

Self-reflection encompasses the dual modes of Integration and Expression, the processes of actively attempting to know oneself and doing something with that knowledge. Each mode serves a distinct purpose; however, the long-standing idea that Integration is needed before Expression can occur has been challenged by the demonstrated ability to create and maintain a small, stable identity through constant Expression. Across three studies, a theory was tested of the Integration mode as a method of quickly and sustainably distributing clusters of organization across the self-structure, allowing for diversity in the selves one can coherently express. Study one replicated the previously observed …


The Internet Did This To Me: Forms, Consequences, And Coping Strategies Of Cyberbullying, Isaac Oppong Aug 2026

The Internet Did This To Me: Forms, Consequences, And Coping Strategies Of Cyberbullying, Isaac Oppong

Electronic Theses and Dissertations

This study examined self-reported cyberbullying experiences recounted in a subreddit (r/cyberbullying) to identify forms of cyberbullying, its effects, and ways to cope with it. The findings indicate that there are several types of cyberbullying, such as verbal aggression, deceptive manipulation, privacy invasion, and coercive control. These experiences led to emotional, social, and behavioral consequences, including fear, anxiety, withdrawal, and decreased online activity. Based on concepts from Social Information Processing theory and Symbolic Interactionism, this study reveals how cyberbullying can produce the same or similar consequences as traditional bullying. People experienced disturbances in their self-presentation, contended with spoiled identities, and dealt …


Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen Aug 2026

Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen

Electronic Theses and Dissertations

Risky behaviors, actions that may cause physical, psychological, social, or economic harm to oneself or others, are prevalent among college students. While significant research has focused on single high-risk behaviors of alcohol use, drug use, gambling, and gaming separately, students frequently engage in multiple high-risk behaviors simultaneously, such as drinking alcohol while gambling. Research shows that students have distinct and specific expectancies about what happens when they engage in a risk behavior, however, minimal research has examined students’ perceptions or reasons for simultaneous poly-risk behavior engagement. This multi-phase project characterized students’ outcome expectancies for simultaneous poly-risk behavior combinations, developed and …

This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …


An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler Aug 2026

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Dynamical Pathways Of Fear And Anger: Testing The Predictive Validity Of The Basic Evaluation Process Framework, Maryana Borri Madeira Jul 2026

Dynamical Pathways Of Fear And Anger: Testing The Predictive Validity Of The Basic Evaluation Process Framework, Maryana Borri Madeira

Electronic Theses and Dissertations

The present study tested the predictive validity of the Basic Evaluation Process framework by examining whether Fear and Anger emerge as competing emotional attractors during threat appraisal. Using a mouse-tracking paradigm with audio recording, fifty participants reasoned aloud about a self-selected threatening situation while continuously rating their Fear and Anger. Cross-correlation analysis confirmed dynamic dependence between Fear and Anger, although the coupling was positive rather than negative, indicating co-activation rather than mutual suppression. Vector field analysis identified stable attractor structures for all participants, but the distribution of primary attractors across the Fear by Anger state space did not reveal a …

Electronic Theses and Dissertations

South Florida hosts a number of non-native wildlife species, including African monkeys. This study examined wild vervet monkeys (Chlorocebus sabaeus) in Dania Beach, Florida, to determine whether aircraft-related atmospheric noise affected their threat detection capabilities and behavioral responses. Using predator-call playbacks and focal scan samples, behavioral data was recorded across pre-, during-, and post-playback phases. Behaviors were labeled as nonvigilant or vigilant. The study also assessed whether responses differed between the local and novel predator calls as well as whether repeated trials suggested habituation over the course of the experiment. Results showed that the monkeys’ abilities to successfully …


Who Do You Think You’Re Talking To? A Longitudinal Study Of How Disclosed Partner Identity Shapes Relational Communication With Ai Among College Students, Vito Anthony Borio Jul 2026

Who Do You Think You’Re Talking To? A Longitudinal Study Of How Disclosed Partner Identity Shapes Relational Communication With Ai Among College Students, Vito Anthony Borio

Electronic Theses and Dissertations

This study presents a longitudinal, two-condition, between-subjects experiment in which partner identity is disclosed as either human or AI in text-based chat; however, all participants (N = 60) interacted with the same chatbot. Informed by both Social Information Processing Theory (SIPT; Walther, 1995) and the Computers Are Social Actors Paradigm (CASA; Nass & Moon, 2000), this design draws on the former’s longitudinal measurement tradition to empirically test whether its predictions hold, using the latter as both a framework and procedure for investigating chatbot interactions. The findings inform both theories, indicating that perceived partner identity significantly affects perceptions of relational …

These sediment core samples were analyzed using a variation of a tested charcoal analysis methodology often used with lake and peat bog cores, but in this case, the cores come from an upland coastal environment. The findings of this project have shown efficacy of the modified methodology for locating charcoal peaks in habitation zones found in core strata and as …


Intra-Individual Cognitive Variability As A Predictor Of Mild Cognitive Impairment In Older Adults: Longitudinal Patterns, Clinical Classification, And Sex Differences, Joshua Conniff Jul 2026

Intra-Individual Cognitive Variability As A Predictor Of Mild Cognitive Impairment In Older Adults: Longitudinal Patterns, Clinical Classification, And Sex Differences, Joshua Conniff

Electronic Theses and Dissertations

Some older adults score differently on the same cognitive test from one visit to the next, and that inconsistency has been proposed as an early warning sign of decline. This dissertation tested whether within-person variability actually tells us anything useful about who has, or will develop, mild cognitive impairment (MCI). A total of 334 older adults completed quarterly neuropsychological testing over three years as part of a larger longitudinal study. Visit-to-visit variability was measured as the mean absolute successive difference on the MoCA, the MMSE, and a battery of memory, executive, language, and visuospatial tasks, and MCI was classified from …
