Tiktok And The Brain: Neuropsychological Correlates Of Short-Form Video Consumption, Caty Enders

Psychology ETDs

Short-form video platforms like TikTok have quickly become the fastest growing segment of social media, thanks to powerful algorithms serving up personalized content driven by large quantities of user data. This study investigates the neuropsychological correlates of digital media use, with a particular focus on TikTok and smartphone screen time among young adults. Combining correlational analyses and an experimental design (n = 49; n = 44 included in final sample), we examined the relationship between digital media use and cognitive and emotional functioning across multiple domains. Objective measures of digital media consumption (daily average screen time and time on TikTok) …

Identity, Sexuality, And Gender: Perspectives From Self-Identified Sexually Fluid People, Mattilyn Wiseman

Psychology ETDs

Research on sexual fluidity has relied on categorical, gender-based measurement frameworks that prioritize quantifying change over exploring the lived experience of sexually fluid people. This study employed Interpretive Phenomenological Analysis (IPA) to qualitatively and ideographically explore how self-identified sexually fluid people made sense of their own sexual identity, gender (more broadly), and attraction as it relates or does not relate to gender. Three participants completed structured interviews with open-ended questions. Participants unanimously made sense of identity as a self-constructed journey and tied to their social realities. Participants’ lived experiences of their own gender identities informed their sense-making of gender more …

Clarifying The Illusory Truth Effect: The Role Of Truth Status And Source Memory, Kamille Koger

Psychology ETDs

The present study investigated whether repetition increases perceived truth even for information explicitly known to be false and how repetition effects interact with source memory. Participants (N = 102) completed two sessions (exposure and test) one week apart. During exposure, they rated the truth of trivia statements presented three times each. Half were explicitly labeled as "true" or "false" (known condition) and half were unlabeled (ambiguous condition). In the test phase, participants judged the truth of all previously seen statements and an equal number of new statements, followed by source memory judgments. Results showed a classic illusory truth effect (ITE) …

The Concept 'Pollination' And Bee Pan-Trap Color And Uv Reflectance Determine The Taxonomic Compositions Of Bee Taxa Captures Across An Elevation Gradient And Seasons In The Jemez Mountains Of New Mexico, Esther A. Burton, Kelly B. Miller, Paul J. Watson, David C. Witherington, Steven Poe, David Lightfoot

Biology ETDs

This thesis examines the pollinator concept and tests how sampling methods shape bee communities. Chapter 1 provides a conceptual and philosophical analysis, arguing that pollination is a process and that pollinators are context-dependent functional roles rather than fixed taxonomic categories. It traces the concept’s development from natural history to ecological theory, introduces a dual-goal model separating plant reproduction from visitor foraging, and proposes a classification framework based on evidentiary certainty and pollination potential to resolve ambiguity in pollination research.

Chapter 2 applies these ideas empirically by evaluating how pan-trap color and ultraviolet (UV) reflectance influence bee assemblages across elevation and …

From Cranes To Clinics: Genomic Epidemiology At The Human-Animal Interface, Sarah Shrum

Biology ETDs

Emerging infectious diseases represent a significant, increasing threat to human life, economic stability, and global security. The One Health framework, which promotes human health and wellness through the understanding that animal, environmental, and human health are interwoven, is critical to understanding pathogen emergence and transmission. This is underscored by the fact that roughly 60% of all human pathogens and 75% of emerging infectious disease are zoonotic, meaning they are transmitted from animals to humans.

The work presented in this dissertation integrates genomic epidemiology, ecological analysis, and One Health Surveillance approaches to characterize cross-species circulation of opportunistic yeast pathogens (Candida …

Reassembling Riparian Ecosystems: Stream Restoration Effects On Vegetation, Arthropods, And Aquatic-Terrestrial Connectivity, Katelyn P. Driscoll

Biology ETDs

Riparian areas exist at the aquatic-terrestrial interface and provide disproportionate ecosystem services, yet multiple stressors have degraded these zones globally. Stream restoration seeks to reverse degradation, but rigorous evaluation of treatment effectiveness remains limited. I conducted a before-after-control-impact (BACI) study in the southern Rocky Mountains to evaluate two stream restoration treatments—beaver dam analogs (BDAs) and plug-and-ponds (P&Ps)—across three dimensions of riparian ecosystem response. Using Bayesian analysis, I quantified treatment effects on functional diversity and composition of riparian plant communities. Using generalized linear mixed models, I evaluated restoration effects on riparian arthropod abundance, richness and guild composition across lateral gradients and …

Sexual Violence By Government Security Forces: Leaders, Institutions, And Culture, Margaret Avera

Political Science ETDs

I assess how the interaction between leader preferences, regime type, and agent personal motives impacts patterns of sexual violence. I ask, “Why do some government security forces perpetrate sexual violence while others do not?” and “How does the interaction between leader motives and institutions impact victimization patterns?” I found that police corruption was correlated with sexual violence by government security forces, but military corruption was not. My findings indicate the importance of moving beyond a conflict scope and distinguishing between different types of state security actors. In addition, I use natural language processing methods to collect disaggregated allegation data to …

Continuous Polygenic Trait Evolution Under Brownian Motion With Gaussian Mixture Models, Mary S. Hopkins

Mathematics & Statistics ETDs

Gaussian mixed-models (GMMs) show promise as a tool for modeling polygenic trait evolution for multiple taxa with established phylogenetic comparative methods (PCMs). When phenotypic traits are influenced by more than one gene, neither a gene tree nor a species tree may be completely adequate to model specific cross-taxa dependencies. In such cases common solutions include using trees inferred from concatenated DNA sequences [35, 95] and consensus gene trees [35]. The GMM-based model, first proposed by Jiang in 2017 [55] allows traits to evolve on more than one tree with distinct topologies. This approach provides a framework for trait evolutionary modeling …

Bayesian Designs For Two-Arm Clinical Trials With Time-To-Event Endpoints: Incorporating Historical Data Through Power Priors, Sara Hajraf H. Almutiri

Mathematics & Statistics ETDs

Bayesian methods provide a flexible framework for time-to-event analysis by incorporating prior information. The power prior offers a systematic way to borrow information from historical data. This approach is especially valuable in clinical research, where historical data can enhance inference in early-phase trials with limited sample sizes. This dissertation develops Bayesian approaches for two-arm survival studies using both closed-form and simulation-based methods. The closed-form inference is derived under exponential and Weibull survival models. Under the proportional hazards framework, the posterior is derived through a normal approximation to the log hazard ratio, allowing inference on the treatment effect when the variance …

Inherited By “Merit”: What Caste Carries Across The Indian American Diaspora, Aarushi V. Jaiswal

English Undergraduate Distinction Projects

This project traces the rhetorical formation termed “meritocratic nationalism,” a political vocabulary that makes national belonging conditional on moralized merit, converting structural advantage into the language of individual character. Meritocratic nationalism is traced across three political figures whose rhetoric represents successive moments in a single ideological trajectory. Reading Narendra Modi’s 2014 and 2018 Independence Day addresses and his 2014 Madison Square Garden speech to the Indian American diaspora as the formation’s originating texts, this project argues that Modi’s recurring moral tetrad of conduct, values, traditions, and ability translated the structurally concentrated advantages of India’s upper-caste professional class into a universalist …

Sayyid Qutb: Political Philosophy And The Global Decline Of Jihadist Legitimacy, Jorge A. Ferrara

Senior Theses

Historically and culturally, the meaning behind political philosophies has been misappropriated to serve new ideological aims, and understanding how contexts have changed is essential to contemporary debates surrounding militant jihadist ideology. Sayyid Qutb, a political philosopher in Egypt during the mid-twentieth century, whose political philosophy, which sought moral, spiritual, and societal reform in Egypt under Gamal ‘Abd-Nasser’s regime, has been classified as the philosopher of Islamic terror. In this thesis, I argue that Sayyid Qutb’s political philosophy has been misappropriated into a politicized and militant jihad ideology through successive reinterpretations by militant jihadist leaders, and that this misappropriation is evidence …

Kenyan Foreign Policy In The Multipolar World, Maryclaire Mcadams

Senior Theses

In April 2025, in a speech to university students in Beijing, China, Kenyan President William Ruto announced, “Ladies and gentlemen, Kenya and China are not merely trade partners. We are co-architects of a new world order.” The speech was a bold departure from Ruto’s announcement just a year earlier that Kenya would officially achieve Major Non-NATO Ally status with the United States. The stark contrast in public statements from Kenya’s president within just a few months signals a shift in the international order. A system that once compelled states like Kenya to bandwagon with the United States now allows them …

A De-Dollarizing World: How Sanctions Catalyze De-Dollarizing Efforts In Russia And China, Karina S. Amaach

Senior Theses

For nearly a century, the United States has occupied the title as the world’s leading superpower nation. Such power has granted the US great economic responsibility, particularly highlighting the dollar’s dominant role as the international reserve and trade currency. However, the rise of competing powers– most notably China and Russia– have posed great threats to this continued economic dominance of the United States. This thesis examines how U.S. economic sanctions– often described as America’s greatest financial tool– have inadvertently motivated de-dollarization efforts led by these two nations. Drawing on interdisciplinary scholarship in foreign affairs, international political economy, and intergovernmental financial …

Evangelical Influences On The Prevalence Of Homophobia In 21st Century Brazilian Politics, Griffin M. Bilello

Senior Theses

In recent decades, Brazil has seen a large influx of Evangelical identification among its population, and this religious group has become a prominent political group that has occupied different positions of power in government. This Evangelical prominence has led to the blocking of LGBTQ+ legislative protections, the protection of homophobic governmental policies, and the perpetuation of anti-LGBTQ+ rhetoric that has threatened the well-being of Brazil’s queer community. This thesis analyzes the social media presence of prominent political figures in Brazil to understand the ongoing discourse regarding homosexuality from different perspectives. Three representatives with varying influences and perspectives were chosen and …

Erinnerungskultur And Pathways Of Division, Christopher C. Wacker

Senior Theses

This paper aims to explain the current political divide between East and West Germany and to investigate whether Erinerungskultur (memory culture) plays a role in this divide. This paper argues that Erinerungskultur played a crucial role in perpetuating the divide. After many years have passed since the reunification, several notable differences between the regions have persisted, particularly in politics. One such difference is the politics of both regions, especially after the most recent election demonstrated a clear blue sweep in the East. This paper will examine the history of both the Federal Republic of Germany (the Western and current state) …

A Study Of Lifestyle Migration In Buenos, Aires Argentina, Sofia Inés Repetto

Senior Theses

Migration is a worldwide phenomenon driven largely by economic, political and social factors. A migrant’s personal aspirations and capabilities play a large role on his/her decision to migration. In my thesis, I aimed to find how the aforementioned fit into lifestyle migration, particularly in lifestyle migration to Argentina. In order to do this, I compared current lifestyle migration to Buenos Aires to the waves of immigration that the nation received during the Age of Mass Migration and in the post-World War II era. I also compared lifestyle migration to the immigration from other Global South nations to Argentina. In this …

Symbolists Beyond The Magic: Appropriation In The Art Of Elihu Vedder And Gustave Moreau, Rebecca B. Shalliker

Art & Art History ETDs

This thesis examines the paintings of Elihu Vedder and Gustave Moreau as examples of how the late nineteenth-century Symbolist movement drew on Eastern regions as aesthetic sources for representing the spiritual. Considering the iconographic and conceptual overlap with the Spiritualist movement, it explores how these groups contributed to constructing an image of the “East” as inherently mystical. While existing scholarship analyzes the Symbolist movement’s engagement with psychoanalytical concepts such as the subconscious and dream state, the role of cultural appropriation in shaping the Symbolist aesthetic has been largely overlooked.

The depiction of Eastern iconography as fantastical will be explored through …

From Body Positivity To Body Power: How Music Therapy And Body Liberation Intersect To Address Body Oppression In The Therapeutic Space–A Literature Review, Katherine M. Perkoski

Expressive Therapies Theses

With the rise of overt fascism, anti–fat bias, anti–intellectualism, anti–multiculturalism, anti–diversity, equity, and inclusion, and the persistence of white, capitalist, cisheteropatriarchy narratives around bodies, music therapists need to recognize how client and therapist bodies show up in practice. In this critical literature review, bodies will be sociopolitically and culturally contextualized, and the intersections of music therapy, body liberation, and body power will be discussed. Music therapists need to address the body oppression faced by sociopolitical identities such as race, gender, disability, age, body size, sexuality, neurodiversity, class, ethnicity, nationality, housing status, and immigration status. The music therapy field needs to …

But Did You Die? An Exploration Of How Humor Can Influence Grief And The Grieving Process: A Literature Review, Sophia Manzi

Expressive Therapies Theses

This literature review examines the power of humor as a defense mechanism amidst death loss grief. The intersection of grief, humor, and expressive arts therapy is under-researched, despite the natural overlap. This work connects concepts of humor with core principles of expressive arts therapy and highlights areas for further research. It contextualizes grief within common Western world frameworks such as the five stages of grief, the dual processing model, and defense mechanisms. Humor presents a nuanced coping skill that has many functions within grief. It can be contradictory in nature, as it can be utilized to resist and combat feelings …

All Together Now! Synchrony As A Pathway For Music Therapy To Improve The Social Strengths Of Individuals Diagnosed With Autism Spectrum Disorder: A Literature Review, Jason Scolnick

Expressive Therapies Theses

Abstract

Music therapy is commonly used to address the social challenges of people diagnosed with autism spectrum disorder (ASD), as it is widely believed to be helpful. Just as the cause and ontology of ASD are not well understood, the mechanisms underlying its social benefits remain unclear. Developmental Music Therapy theorizes that developing sociability is a matter of expanding consciousness. In this literature review, I examined the plausibility that music therapy uses synchrony (individuals’ behavioral, neural, and/or physiological systems acting together in time) as a pathway that enhances the sociability of autistic people. The literature indicated that a wide variety …

Bridging The Gap - Integrating Dance/Movement Therapy (Dmt) Into Support Frameworks For Children With Developmental Coordination Disorder: A Literature Review, Anjelica R. Espinoza-Flores

Expressive Therapies Theses

Developmental Coordination Disorder (DCD) affects approximately 5% to 6% of school-age children globally. While the primary symptoms involve challenges with motor coordination, the impact often extends to a child’s social and emotional well-being, leading to increased anxiety and social isolation. Current interventions, such as occupational and physical therapy, focus largely on functional skill-building. However, these methods may not fully address the emotional and psychological experiences of the child. This thesis explores how Dance/Movement Therapy (DMT) can serve as a vital link between physical rehabilitation and emotional support. By examining research on neurobiology and therapeutic movement, this paper argues that DMT …

Cultivating Compassion To Support Stabilization: A Practice-Based Group Model For An Inpatient Psychiatric Trauma Unit, Sarah E. Condon

Expressive Therapies Theses

In inpatient psychiatric settings, treatment is typically oriented toward short-term stabilization rather than trauma processing. This thesis explores how self-compassion and expressive arts therapy may support stabilization for individuals with complex trauma histories, highlighting the role of self-criticism and shame as key mechanisms underlying trauma-related distress. This thesis presents the development of a multi-group therapy model implemented on a 21-bed inpatient trauma and dissociative disorders unit. The model pairs psychoeducational, compassion-oriented groups, grounded in mindful self-compassion (MSC) and compassion focused therapy (CFT), with subsequent expressive arts therapy (EXAT) groups with the intention of cohesively integrating and deepening these themes through …

Attachment Under Threat: Parental Cancer, Child Development, And Dance/Movement Therapy As An Embodied Intervention—A Literature Review, Victoria E. Groves

Expressive Therapies Theses

Parental cancer is a significant family-based stressor that can disrupt children’s attachment security and emotional regulation. This literature review examines how parental cancer can interfere with parent-child attachment processes and explores dance/movement therapy (DMT) as a potential intervention. Literature from attachment theory, psycho-oncology, trauma research, somatic psychotherapy, and DMT is synthesized into a cohesive conceptual framework linking caregiving disruption, neurobiological stress responses, and embodied patterns of regulation in children. Findings suggest that parental cancer is associated with increased attachment insecurity through changes in caregiver availability, emotional attunement, and children’s perceived attachment security. These disruptions contribute to the internalization of chronic …

Re-Painting Motherhood: A Community-Based Expressive Arts Project Exploring Motherhood’S Myths, Realities, And Hopes Through A Narrative Therapy Lens, Lauren Grignaffini-Morris

Expressive Therapies Theses

This thesis examines how socially constructed ideals of motherhood shape maternal identity, distress, and isolation, and explores the potential of addressing these experiences through a community-based expressive arts project. Drawing on motherhood studies, expressive arts therapy, and narrative therapy, the project highlights the potential benefits of utilizing expressive arts in a community setting to ease the tension between romanticized cultural narratives and the lived realities of mothers. Conducted with a support group for mothers in rural Vermont, the project used visual art, movement, creative writing, and collaborative mixed-media painting to examine problem-saturated motherhood stories, connect through embodied experience, and explore …

Arts-Based Violence Prevention For Youth: A Literature Review, Amber Lynn Isaac

Expressive Therapies Theses

This narrative literature review examines arts-based approaches to violence prevention and trauma-related support among school-aged children and adolescents in school and community settings. Violence is conceptualized as both interpersonal and structural, encompassing physical, emotional, relational, and systemic harms that arise through unequal access to safety, opportunity, and resources. The review then explores how these conditions increase vulnerability to trauma exposure, particularly among youth in marginalized and underserved communities, and considers the psychological impacts of violence on youth development. Centering the resilience of children and adolescents through relational strengths, adaptive coping strategies, and creative capacities, this review then examines the benefits …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

The Pastoral Implications Of John Calvin's Genevan Psalter For Church Music Ministry In Hong Kong, Sze Man Symantha Leung

Doctor of Pastoral Music Projects and Theses

The aim of this thesis is to interpret the pastoral meaning and function of Calvin’s Genevan Psalter and to illustrate how it can be applied to Hong Kong church music ministry today. Through the Genevan Psalter, Calvin advocates congregational and vernacular psalm‑singing in Reformed worship. He emphasizes piety, Scripture, congregational participation, and the shaping of daily spirituality beyond Sunday worship. The pastoral insights drawn from the use of the Genevan Psalter in Reformed worship offer five valuable implications for music ministry in Hong Kong today: Spirituality, Unity of the Church in Faith, Theological Education, Liturgical‑Musical Interrelationship, and Inclusiveness.

In addition …
