The Psychophysiology Of Primary And Secondary Variants Of Psychopathic Traits In Youth, Ines Guariguata

Dissertations, Theses, and Capstone Projects

Psychopathy is a cluster of personality traits marked by a pervasive callousness, lack of shame or remorse, deceitfulness, a persona of confidence and charm, shallow emotional connection, general lack of insight into their actions, and an absence of anxiety (Glenn & Raine, 2014; Hare, 2003). Research suggests that there are distinct etiological pathways to the development of psychopathic traits and that their responses to treatment are different (Craig et al., 2021; Yildrim & Derksen, 2015; Fleming et al., 2023). Primary variants show a low-fear, low-anxiety profile during stress, and have a genetic basis (Craig et al., 2021; Yildrim & Derksen, …

Inherited Wounds: Generational Trauma In Postcolonial Film And Narrative Fiction Of The Global South, Sabrina Testi Melgarejo

Dissertations, Theses, and Capstone Projects

The theorization of trauma in literary studies emerged in the 1990s, evolving from its physiological origins to a multidisciplinary framework encompassing literature, psychology, and history. However, classical trauma theory, rooted in Western scholarship and focused on singular traumatic events, has been criticized for its limitations in addressing collective and ongoing trauma in non-Western contexts. This thesis responds to a call for a more inclusive approach to trauma studies, examining how multi-generational and cultural trauma is represented in non-Western postcolonial films and literature from the Global South, including works from the Philippines, Sri Lanka, Cuba, Angola, Mozambique, Vietnam, and Lebanon.

Beauty Comes With A Price: But How Much Is It Worth It, Fabliha Afia

Dissertations, Theses, and Capstone Projects

The global skincare market, valued at 104.24 billion dollars in the year 2022, is very heterogeneous, ranging from prestige brands to more drugstore types. Even when the same key ingredients are present, the latter often sells for much higher due to branding and packaging and the aura of prestige created. This capstone project entitled "Beauty comes with a price: but how much is it worth?" investigates if such higher costs are justified due to superior quality or are driven by non-functional factors. It systematically compared the high-end versus drugstore skincare products in categories like sunscreens, serums, and exfoliants with respect …

Quantifying The Individual Bilingual Experience Through A Lens Of Language Dominance, Leeann Stover

Dissertations, Theses, and Capstone Projects

This article-based dissertation addresses some of the issues regarding the multifaceted nature of bi/multilingualism, focusing on the significance of individual variation in the measurement of language dominance. While age of later-acquired languages has traditionally been used to classify bilingual speakers into early and late bilinguals, the construct of language dominance has emerged as an additional criterion of classification. However, despite its utility in capturing dimensions of language experience beyond age of acquisition, the construct of language dominance has its own challenges of measurement and individual variation.

This dissertation focuses on two open-ended challenges in the quantification of language dominance: how …

Guaqueras And Campesinas In Western Boyacá, Colombia, María F. Buitrago

Dissertations, Theses, and Capstone Projects

Guaqueras and Campesinas in Western Boyacá (https://mariabuitsan.github.io/guaqueras-ycampesinas/) is a digital memory project chronicling the lives and labors of women residing in the emerald-producing municipalities of Colombia. The project explores women’s remarkable resilience amidst a historically extractive and patriarchal emerald economy by co-creating an online collection enriched with various sources such as interviews, photos of artifacts, and audio from fieldwork. The collection uses Dédalo, a free and open-source Cultural Heritage and Management System, to store, digitize, and index all the unedited material and presents a selection of these resources through a static website. The collection intends to illuminate and honor the …

Testing Toxicity: Two Approaches To Toxicity Detection, Nelson E. Jarrin

Dissertations, Theses, and Capstone Projects

The current online environment is increasingly being polluted by polarization, echo chambers, and a lack of constructive dialogue between individuals with differing viewpoints. Social media algorithms, while intended to personalize user experiences and marketing areas, have been heavily criticized for inadvertently amplifying extremist content and contributing to the spread of toxic commentary. The current state of the internet hinders productive conversations, fuels misinformation, entices disinformation and contributes to online and offline societal division. This is fueled by algorithms that can create echo chambers and by the anonymity given by online platforms. While tools like the Perspective API exist to identify …

Love In The Time Of Dating Apps: Exploring Latino Young Adults’ Experiences Constructing Online Identity, Partner Preferences, And Plans For Happily Ever After, Dakota Z. Ross-Cabrera

Dissertations, Theses, and Capstone Projects

This dissertation examines how Latino young adults navigate dating apps; construct their dating app profiles, select partners and develop preferences, and conceptualize their futures. While earlier dating app research explores these themes with quantitative data or with non-Latino samples, the qualitative experiences of Latino young adults have been broadly excluded. Latinos are a large portion of the dating app market, and their relationships, outcomes, and future family formation are integral to understand. Drawing on 60 qualitative interviews with Latino young adult dating app users, I find that app users encounter five stages of dating app usage including constructing and often …

Imaging Markers Of Future Neurodegeneration Following Moderate-Severe Traumatic Brain Injury, Daniel Brennan

Dissertations, Theses, and Capstone Projects

The overall goal of this dissertation was to identify patterns of cerebral atrophy following traumatic brain injury and relate relevant imaging measures to that atrophy. In Chapter 2, we outline a spatiotemporal profile of atrophy in the first year following moderate-severe TBI: prior to 3-months post injury, the frontal and temporal cortices were observed to be thinner than controls, and thalamic volumes were reduced. From 3-12 months post-injury, significant atrophy was observed in white matter, subcortical gray matter structures (including thalamus), and cortical thinning was observed in the parietal and occipital cortices.

In Chapter 3, we identified widespread white matter …

A Mute Pleasure: Novelistic Poetics In The Nineteenth-Century, Ryan Everitt

Dissertations, Theses, and Capstone Projects

Through special attention to the non-narrative, descriptive, lyrical, or even boring passages that interrupt the story, this dissertation explores what happens when the nineteenth-century British novel envelops experiences that were traditionally (or since Romanticism) in the domain of poetry: longings for escape, exhilarating affects of freedom, opaque moments of revelation. In most cases, I characterize the novel discourse as representing a prosaic consciousness that wrestles with its more visceral yet vital “other,” poetic consciousness. To articulate how poetry survives within novelistic discourse, this dissertation is organized around sets of opposing terms, whose unresolved tension becomes the basis of my analysis …

The Effects Of Mood And Anxiety Sensitivity On Attentional Engagement And Disengagement In Sleep Disturbance, Kara L. Buda

Dissertations, Theses, and Capstone Projects

Insomnia is a highly prevalent, chronic disorder that is associated with adverse psychological, physical, and psychosocial outcomes. Harvey’s (2002) cognitive model of insomnia and Espie’s (2006) attention-intention-effort pathway model highlight two critical processes believed to play a role in the onset and persistence of insomnia: (a) emotional distress and physiological arousal and (b) selective attention and monitoring. However, investigations examining attentional bias in sleep disturbance have produced mixed results and have exclusively used paradigms that are limited in their ability to differentially examine the two unique components of attentional bias (i.e., facilitated engagement, impaired disengagement). Discrepant findings in the attentional …

Investigating The Impact Of Affect In Suicide-Specific Attentional Biases, Beverlin Rosario-Williams

Dissertations, Theses, and Capstone Projects

Objective: Biased processing of suicide-related information has been implicated in risk of future suicidal thoughts and behaviors. Although previous studies have classified this biased processing, the tasks used to examine these biases cannot definitely specify which attentional processes are related to risk for suicidal thoughts and behaviors. Therefore, via two independent studies, this dissertation sought to distinguish suicide-specific attentional engagement and disengagement biases from other forms of cognitive processing, such as accessibility of suicide-related stimuli and threat bias toward and away from socially threatening stimuli. Additionally, this dissertation investigated under which affective conditions suicide-specific engagement and disengagement biases emerged. …

Defining Resilience In Young People With Inflammatory Bowel Disease: A Theory Informed Approach, Barbara Storch

Dissertations, Theses, and Capstone Projects

Inflammatory Bowel Disease (IBD) is a chronic gastrointestinal illness for which there is no existing cure. There is significant literature documenting the increased likelihood of adverse biopsychosocial outcomes in young people with IBD (e.g., Greenley et al., 2010); however, many individuals with IBD respond by either maintaining or increasing outcomes categorized as positive. These trajectories can be thought of as characterized by a resilient response. The study of resilience in young people with IBD is nascent. Given the unique disease-specific and developmental contexts young people with IBD experience, the first step in understanding the process of resilience in young people …

Lgbtq+ Employees’ Disclosure And Selective Incivility Experiences: Implications For Their Health And Well-Being, Wiston A. Rodriguez

Dissertations, Theses, and Capstone Projects

Workplace incivility refers to low-intensity rude behaviors at work that have an ambiguous intent to harm and also violate workplace norms of mutual respect. Given the negative consequences associated with workplace incivility, researchers have been trying to understand potential antecedents to experienced workplace incivility such as target characteristics or group affiliation. Prior research suggests that uncivil behaviors may not be enacted at random and may manifest in the form of selective incivility (i.e., subtle discrimination). Specifically, selective incivility is a form of targeted mistreatment that is used to oppress and exclude minorities in the workplace and is a unique experience …

The Intellectual Roots Of Hindutva: Influences From Early German Romantics And Mahatma Gandhi, Johannes Scheuer

Dissertations, Theses, and Capstone Projects

The economic and political ascent under the leadership of the Bharatiya Janata Party (BJP) and Narendra Modi has not only increased interest in Indian politics but also highlighted the dominance of Hindu nationalism (Hindutva) as a political ideology in contemporary India. Many scholars and journalists have drawn parallels between European fascist movements of the past and reactionary movements in today's political landscape to understand the rise and dominance of Hindutva. However, this paper takes a different approach by tracing the intellectual roots of Hindutva through the political philosophy of the Early German Romantics, particularly Johann Gottfried Herder, and the philosophy …

Computerized Cognitive Training In The Treatment Of Depression: Individual Differences And Perceptions Of Cct, Sophie Schiff

Dissertations, Theses, and Capstone Projects

Major Depressive Disorder is a serious mental health disorder that affects 8% of adults in the United States. Adults aged 18-29 are at an elevated risk with a prevalence of 12%. Depression is most often characterized by mood symptoms, however, individuals with depression often also present with cognitive weaknesses on objective neuropsychological measures across several domains. These deficits are not only associated with mood symptoms, but significantly interfere with treatment and have been found to persist even with successful treatment of affective symptoms. Research into interventions directly targeting cognition has increased in recent years. While traditional first-line treatments for depression, …

Claiming The Right To Belong: Diversity And The Politics Of Inclusion In Queens, New York, Susan J. Tanenbaum

Dissertations, Theses, and Capstone Projects

This dissertation examines social integration in a diverse civic and political mainstream. The social science research on intergroup contact in U.S. cities undergoing significant demographic change tends to focus on encounters between members of majority “in-groups” and minority “out-groups” in the context of workplaces, neighborhoods, and families. I contend that civic politics is another compelling strategic site for observing intergroup contact between emerging and established players. My study presents three cases of claims-making activity during the post-9/11 period in New York City’s borough of Queens, where close to 50% of the population is foreign-born and no single racial group predominates. …

Building Networks, Producing Spaces For Play: Local Geographies And National Organizing In The History Of Adventure Playgrounds In The United States, 1949-1999, Reilly B. Wilson

Dissertations, Theses, and Capstone Projects

This dissertation provides an historical analysis of repurposed material adventure playgrounds in the United States between 1949 and 1999. Three microhistories of adventure playgrounds (The Yard, in Minneapolis, M.N., and several playgrounds in New York City, N.Y., and Houston, T.X.) are framed against the wider socio-economic changes that shaped more than thirty-five adventure playgrounds in the United States over the period of study. By focusing on the relationships mobilized by adventure playground advocates at different scales and across different points of view, and how these networks shaped the local production of spaces for play, this dissertation's method underlines the importance …

Association Of Autistic Traits And Psychiatric Symptoms In Children With A Fragile X Premutation Allele: The Neurodevelopmental Profile, Ariel Zucker

Dissertations, Theses, and Capstone Projects

Throughout the lifespan, approximately 14% of males and 5% of females with a fragile X premutation (PM) (defined as 55-200 CGG repeats on the X-linked FMR1 gene) are diagnosed with Autism Spectrum Disorder (ASD). For individuals that do not meet diagnostic criteria for ASD, autistic traits (ATs) are often present in this population and have been shown to have a subtle and sub-clinical presentation of social communication and interaction deficits. While less is known about the phenotype of children with a PM, studies have found increased rates of ASD and ATs in adults with a PM allele compared to controls. …

Late-Life Depression: The Interplay Between Cerebrovascular Risk, Cortical And Subcortical Atrophy, And Treatment Response, Dakota Egglefield

Dissertations, Theses, and Capstone Projects

Late-life depression (LLD) is associated with poor response to antidepressant medication treatment, cognitive impairment, cerebrovascular disease, and brain changes both in white and gray matter. Of particular interest is the vascular subtype of LLD, vascular depression (VD). Although LLD and VD have received considerable research attention, there are still areas that must be further clarified to adequately characterize aspects of LLD and VD that provide valuable information for possible interventions. Such areas include a stronger understanding of the moderating role of brain atrophy and changes in cognition in treatment response in LLD. This dissertation consists of three separate studies aimed …

Perceptual Expectation, Rebecca Keller

Dissertations, Theses, and Capstone Projects

You are currently seeing many things, and, hopefully, you are currently about to see many other things. Many of the things that you are about to see will not be surprising, because you expect to see them. Sometimes, though, when you expect to see one thing and are faced with another, that thing will look like the thing you expected it to be, and not like the thing it actually is. This dissertation is an attempt to get a handle on what is happening in the visual system in these instances. In particular, I am trying to figure out what …

Measuring Intersectional Strength And Stigma Among Racially Minoritized Gender Diverse Young Adults, Joseph Carter

Dissertations, Theses, and Capstone Projects

Background: Racially minoritized transgender and gender expansive young adults (RMTGEYA; aged 18-26) experience mental health inequities due to intersectional, multilevel stigma. RMTGEYA communities embody intersectional strength and resilience that can mitigate the impact of stigma. Understanding and capturing strength and stigma factors to address these inequities has significant implications for clinical science research and practice. There is, however, a complete absence of instruments that are validated to do so. Objective: The goal of this study is to conduct a three-phase, mixed methods study that centers intersectional and community engaged methods of psychometric development for a measure that captures daily experiences …

Liberal Attitude Reports, Tomasz Zyglewicz

Dissertations, Theses, and Capstone Projects

Attitude reports are sentences such as “Tomasz thinks the Earth is flat” or “Susan wantsvice cream.” It is commonly assumed that the main reason people use them is to make sense of the reportee’s behavior: to explain their past actions, or predict future ones. To play this role effectively, attitude reports have to accurately describe what is going on in the reportee’s head. Let’s call attitue reports that do not meet this condition “Liberal attitude reports.” For example: Alice is a vegan doctor who thinks that every vegan should take a B12 supplements. It is felicitous to say to your …

Loneliness And The Urban American (Non-)Romantic, Sarah C. Cook

Dissertations, Theses, and Capstone Projects

Loneliness, also known as ‘perceived social isolation,’ is an increasingly common feeling among Americans. It can be critically unhealthy when chronic, and recent revelations about its health effects have garnered a significant amount of media attention. Although statistical evidence tells us that marriage is the strongest defense against loneliness, over a third of Millennials and Gen-Zers say marriage is outdated; and census data shows that living alone is both one of the fastest-growing demographics in America, as well as a relatively stable housing arrangement. After examining existing research and media reports on loneliness itself in some depth, including factors that …

The Film, The Stadium And The Jail: The Post-Industrial Transformation Of Downtown Durham, Seth Rose

Dissertations, Theses, and Capstone Projects

By the late 1980s, Durham, North Carolina’s downtown-based industrial economy had been replaced by a powerful knowledge economy in the city’s peripheries. Downtown Durham’s vast array of tobacco and textiles manufacturing buildings stood empty, along with most of its commercial spaces, offices and sidewalks. This thesis argues that the local development of two major public works, a baseball stadium (the Durham Bulls Athletic Park) and a jail (the Durham County Detention Center), conceived and constructed on similar timelines in close physical proximity, was indicative of how—and for whom—city and county officials envisioned a revitalized downtown. The first chapter examines the …

The Impact Of Early Teacher Bias And Academic Risk On Children’S Current And Future Academic Achievement, Damira S. Rasheed

Dissertations, Theses, and Capstone Projects

The racial academic achievement gap continues to plague child academic outcomes in American public schools and teacher bias may be a contributing factor. Through the theoretical lens of critical race theory and the cultural synchrony hypothesis, this study contemplated how longstanding racism in the US may function to hinder the academic achievement outcomes of minority-race children. Moreover, cultural mismatches in the classroom between teachers and students may be associated with lower quality teacher-child relationships and perceived academic risk. A growing body of work has examined the association between teacher bias and child academic-risk factors—with risk defined by children’s sociodemographic characteristics …

Future Land, Futures Lost: Planning The Crisis On The Louisiana Coast, Sheehan Moore

Dissertations, Theses, and Capstone Projects

South Louisiana is rapidly losing coastal land to the combined forces of subsidence, sea-level rise, and worsening storms, accelerated by the effects of flood control engineering and extractive industrial development. With erosion threatening homes and industry alike, the state has marshaled a response on a massive economic and geographic scale: its Coastal Master Plan recommends $50 billion in river sediment diversions, barrier island restoration, and other projects over fifty years. This dissertation is about the emergence of Louisiana’s coast as a place from this knot of human and environmental relations, as an object for governance and a container for political …

The Effect Of Working Memory Performance Under Stress On The Relationship Between Trauma History, Ptsd Symptoms, And Intimate Partner Violence, Gabriella Robinson

Dissertations, Theses, and Capstone Projects

Background: Over 12 million people annually experience intimate partner violence (IPV) in the United States. Emerging adulthood has the highest rates of IPV across the lifespan. While many theories attempt to explain why IPV rates are markedly increased during this age period, researchers call for more empirical studies to understand processes occurring during this period that result in increased IPV perpetration. Of the studies that assess IPV perpetration, samples generally consisted of male batterers that perpetrated severe IPV. Trauma history and PTSD symptoms have been seen as risk factors for IPV perpetration. Cognitive risk factors for IPV perpetration, such as …

Living Color: Aesthetic Surfaces And Political Life In Brazil, Samuel E. Novacich

Dissertations, Theses, and Capstone Projects

This dissertation is about the manipulation of appearances – of both the human body and the built environment – in Rio de Janeiro, Brazil. Focused on Afro-aesthetic makeup and tanning practices as well as urban renewal projects, this ethnographic study reveals how the making over of both the skin and the urban landscape shape social inequalities and contribute to productions of race, gender, and national belonging. While some of the aesthetic technologies examined herein may be characterized as “bottom up” – or as the self-fashioning tactics of marginalized Afro-Brazilians – others constitute “top down” infrastructural interventions led by the state …

Intimate Partner Violence And Negotiation During Covid-19: Stressors, Resources, And Perception, Victoria P. Diamond

Dissertations, Theses, and Capstone Projects

Intimate partner violence (IPV) is a serious public health concern that affects millions across the globe. The COVID-19 pandemic created unforeseen stress, and necessitated safety policies that required social isolation, often extended exposure to one’s intimate partner, and an inability to access stress-reduction resources. These factors, along with many others, lead to an abrupt increase in IPV in many couples. Using the couple-adapted family stress model (ABCX), the current study examines both previously defined (e.g., emotional dysregulation, stress, unemployment, communication issues) and COVID-19 specific risk (e.g., quarantine, unprecedented social isolation, fear of contracting COVID-19) and protective factors (e.g., meaning in …

Response Styles In Multiscale Measures, Zebing Wu

Dissertations, Theses, and Capstone Projects

Response style, one common aberrancy in non-cognitive assessments in psychological fields, is problematic in terms of inaccurate estimation of item and person parameters, which leads to serious reliability, validity, and fairness issues (Baumgartner & Steenkamp, 2001; Bolt & Johnson, 2009; Bolt & Newton, 2011). Response style refers to systematic individual preference or avoidance of certain response categories (Bolt & Johnson, 2009), especially in self-reported Likert-type scales. When response style occurs, the selection of response options is not only influenced by the trait(s) of interest but also affected by one’s tendency to choose specific options stylistically.

Despite the fact that the …
