Effects Of Social Comparison Instructions On Affect, Motivation For Healthy Behavior, And Health Behavior Selections: Guidance To Identify Or Contrast, Raj Harsora

Theses and Dissertations

Engaging in healthy behaviors early in life is crucial for preventing noncommunicable diseases such as type 2 diabetes, cancer, and heart disease. College is an optimal period to establish these habits, yet students often engage in poor dietary and physical activity practices; thus, identifying effective health behavior change techniques for this population is essential. Social comparisons are known to influence health behaviors, yet no research has tested comparison instructions as a behavior change technique, particularly identification versus contrast with upward and downward targets. Using a preregistered protocol (https://osf.io/z29en), we tested whether guiding college students (N=664) to identify with or contrast …

Problematic Technology Use And Quality Of Life In College Students With Varying Levels Of Schizotypy, Joseph P. Skinner

Theses and Dissertations

Problematic Technology Use (PTU) has emerged as a growing concern with technology’s continual integration into daily living. Individuals higher in schizotypy may be particularly vulnerable to the negative consequences of digital environments. The present study cross-sectionally examined associations among schizotypy, PTU, and quality of life (QOL) in 533 college students using structural equation modeling. Consistent with hypotheses, greater total schizotypy was associated with higher PTU and lower QOL. Additionally, positive, negative, and disorganized schizotypy all uniquely predicted poor QOL with the negative domain demonstrating the strongest standardized association. Contrary to hypotheses, PTU did not significantly moderate the relation between total …

Data sources …

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

Workers Authoring Assessment: Play And Power In Early Childhood Education, Phoebe M. Gilpin

Theses and Dissertations

Researchers assert that play-based pedagogy is an effective approach to teaching young children, but there is less consensus on the specific methods of play-based teaching. This mixed-methodology exploratory case study investigated early childhood (EC) educators’ conceptualizations of play-based pedagogy in three phases: Phase 1’s quantitative measure testing found a mismatch between researchers’ conceptualization of play-based pedagogy and EC educators’ (n=183) understandings. In Phase 2, EC educators (n=3) articulated their perspectives about teaching through play and co-authored a new tool, the Teacher-Authored Play and Teaching Scale (TAPTS). Within Phase 3, EC educators (n=60) completed the TAPTS, which I interpreted through a …

Theses and Dissertations

Hydrologic data are the cornerstone of many complex hydrologic research and operational workflows that produce useful hydrologic information for water resources decision-making, flood risk communication, and water availability implications. The National Water Model (NWM) is a valuable source of hydrologic data, particularly for its extended coverage of unmonitored streams and the large-scale continuity of hydrologic processes. Precomputed secondary datasets derived from this simulated data, such as streamflow indices, can improve operational efficiency through thresholding. Disseminating the data through modern technologies, such as application programming interfaces, is required for ready integration into applications. However, if extraction requires an intermediate service, there …

"Tithing Is An Insurance Premium": A Framing Analysis Of Speaker Innovation And Diachronic Trends In Latter-Day Saint Religious Discourse, Reid Empey

Theses and Dissertations

Religious language relies on shared metaphor and frames that contextualize religious experience and practice. Current approaches to frame semantics (Fillmore 1982) and cognitive metaphor (Lakoff & Johnson 1980) lend important insight into religious language, particularly in describing the role that figurative language serves in a religious speech community. However, a vital component of many religious speech communities is the presence of and engagement with a scriptural canon, which often contains metaphorical and framing language that religious speakers can directly reference. Yet, past conceptualizations of speech communities have not accounted for this engagement with a shared canon. To illustrate the role …

Family Religious Socialization Index: Development And Preliminary Validation, Kaelie Rene Crockett

Theses and Dissertations

A key area of interest for religious scholars is how religious beliefs are passed across generations, or religious socialization. To expand this field of study, a theoretically grounded, validated measure of this construct is needed. This article describes the development and validation of the Family Religious Socialization Index (FRSI), a multi-informant, multidimensional assessment of the processes through which parents socialize religion and faith in their children. Based on Social Cognitive Theory and through a rigorous development and validation process, three subscales were developed to represent the primary processes of religious socialization. The FRSI consists of two parallel scales, a parent …

Threads Across The Atlantic: A Dialogue Of Feminist Writings Between Portugal And Cape Verde, Elliana Shillig Venancio

Theses and Dissertations

This thesis examines the feminist literary traditions of Portugal and Cape Verde through a comparative analysis of Ana de Castro Osório’s Infelizes and Dina Salústio’s Mornas eram as noites. Separated by nearly nine decades and an ocean, these two works nonetheless converge in their insistence on women’s autonomy, bodily sovereignty, and resistance to patriarchal structures. Drawing on Hélène Cixous’s theory of écriture féminine and Kimberlé Crenshaw’s framework of intersectionality, this thesis argues that despite the significant differences in time, geography, and socio-political context that separate these authors, powerful threads of feminist consciousness bind their writing together. At the same time, …

Intensification Of Thermal Energy Storage Systems Based On Sodium Nitrate, Hari Suthan V Mr

Theses and Dissertations

Thermal energy storage (TES) systems employing phase change materials (PCM) bridge the gap between thermal energy demand and supply. The low thermal conductivity of sodium nitrate (NaNO3), an inorganic PCM for high-temperature TES systems restricts charging and discharging kinetics, reducing system-level performance. This thesis investigates the intensification of sodium nitrate-based thermal energy storage systems through the incorporation of different classes of additives. Metal oxides (zinc oxide and aluminium oxide) and carbon-based materials (graphene oxide (GO) and expanded graphite (EG)), were incorporated into NaNO3 to improve its thermophysical properties (thermal conductivity, latent heat, specific heat).

Composites were prepared using low-energy ball …

A Coupled Reaction-Diffusion Model Of Promoting And Suppressing Interactions Among Cancer Hallmarks In Endometrial Cancer, Jeddy Bennett

Theses and Dissertations

Spatial transcriptomics enables the scoring of Cancer Hallmarks at a high resolution across a tissue biopsy, yet current analyses of these data remain largely descriptive, treating each spot as a static, independent observation. This thesis develops a coupled system of advection-diffusion-reaction partial differential equations to model the hallmark landscape as the steady-state solution of an underlying spatial process, and casts the recovery of its physical parameters as a PDE-constrained inverse problem. The framework is implemented in FEniCSx on tissue-specific finite element meshes derived from two endometrial cancer biopsies provided by the Huntsman Cancer Institute, with subdomains, boundary interfaces, and an …

Media Emotion Regulation And Executive Function In Childhood: Associations With Respiratory Sinus Arrhythmia, Lara M. Almeida

Guided by the Dynamic, Relational, Ecological Approach to Media Effects Research (DREAMER) model, this study examined longitudinal associations between MER and executive functioning (EF) in early childhood and explored whether respiratory sinus arrhythmia (RSA), a physiological index of regulation, predicted developmental changes. Participants included 175 parent-child dyads assessed across two annual waves when children were approximately 4 and 5 years old. Structural equation modeling was used to test bidirectional associations between MER and EF while …

Physical Activity, Trauma, And Posttraumatic Stress: The Indirect Role Of Exercise Addiction, Anastasiia Rozumna

Theses and Dissertations

Exercise is often conceptualized as a protective factor for mental health, including for individuals exposed to trauma. However, less is known about whether exercise may relate to posttraumatic stress symptoms differently when it is accompanied by compulsive or addictive features. The present study examined whether volume and intensity of physical activity were associated with posttraumatic stress symptom severity indirectly through exercise addiction symptoms. This secondary cross-sectional analysis included 557 adults living in the United States who reported regular participation in sport or physical activity. Participants completed self-report measures of physical activity behavior, exercise addiction symptoms, trauma exposure, and posttraumatic stress …

A Systematic Review Of Posttraumatic Stress Disorder Among Hispanic Immigrants In The United States, Rashel Acireale

Theses and Dissertations

This study systematically reviews the literature on posttraumatic stress disorder (PTSD) among Hispanic immigrants in the United States, a population exposed to cumulative trauma across the migration process. Stressors may occur before, during, and after migration and include violence, family separation, dangerous travel conditions, discrimination, and fear of deportation. Despite these risks, findings on PTSD prevalence remain mixed, and Hispanic immigrants are underrepresented in clinical research and culturally informed interventions. This review examines sample representation, types and timing of trauma, PTSD measurement approaches, and the inclusion of cultural and contextual factors such as acculturation and immigration-related stress. It also evaluates …

Depictions Of Girls With Adhd In Contemporary Picturebooks: A Critical Content Analysis, Madison Briann Smith

Theses and Dissertations

This study examines how girls with ADHD are depicted in contemporary picturebooks through the theoretical framework of critical disability studies (CDS). While research has increasingly explored disability representation in children's literature, depictions of girls with ADHD remain underexamined despite the ways in which ADHD manifests in female populations and the historical underdiagnosis of females with the condition. Using critical content analysis (CCA), six contemporary picturebooks featuring female protagonists with ADHD were analyzed for their visual and textual representations of neurodiversity. Findings were organized into two overarching themes: strength-based and deficit-based depictions. Strength-based portrayals emphasized creativity, identity formation through adult mentors, …

Resonant Shock Plate Simulation And Prediction Using Modal Substructuring, Harrison C. Denning

Theses and Dissertations

Aerospace structures such as rockets can experience various shock events during flight, such as stage separation or impacts. These shock events can expose components inside the rocket to large accelerations and stresses which in turn can damage the parts. Shocks are often simulated in the lab using a resonant shock plate test. Resonant shock plate testing is often used to qualify aerospace parts, as it can mimic the shocks experienced during launch and stage separations. However, during the course of development, both the definition of the shock environment and the design of the subcomponent tend to change, so that multiple …

Rfsoc Based Ground Penetrating Radar For Detection And Avoidance Of Underground Utilities, Brady Bowerbank

Theses and Dissertations

Preexisting underground utilities present a considerable danger to underground boring projects. Gas and electrical lines can be damaged, leading to major economic impact and even loss of life. While maps of underground utilities exist, they are not always accurate and gas and electrical lines can shift over time, necessitating tools to accurately detect utilities so that crews can steer the machines away from any possible danger. In this thesis, the design of a new frequency-modulated continuous-wave (FMCW) ground penetrating radar (GPR) is outlined. The design of a lightweight, flexible radar is demonstrated using the CASPER FPGA framework with an operating …

Thermophysical Property Studies: 1. Thermodynamic Consistency For Associating Compounds 2. Autoignition Temperature, Cassandra Jane Guffey

Theses and Dissertations

Accurate thermophysical property data are essential for the design, optimization, and safe operation of chemical processes. Properties such as vapor pressure, enthalpy of vaporization, heat capacity, density, and autoignition temperature--which are among the properties studied in this work--are required for equipment sizing, process simulation, hazard assessment, and economic evaluation. A major focus of this dissertation is the application of multi-property thermodynamic consistency techniques to compounds that exhibit strong vapor-phase association. These methods improve confidence in recommended property values by enforcing rigorous thermodynamic relationships among ideal-gas heat capacity, liquid heat capacity, vapor and liquid densities, vapor pressure, and enthalpy of vaporization. …

Recognition Of Autism Characteristics In Females: An Examination Of Stakeholders, Laurel Lyn Bishop

Theses and Dissertations

Autism is a neurodevelopmental communication disorder, characterized by differences in social communication, attention, interests, and sensory perception. Diagnostic criteria have historically applied to males, but clinical diagnostic criteria beginning in 2022 now include slight differences in traits comprising the female phenotype. Until recently, autistic females may be missed by the professional and education community or diagnosed later than males. Like their autistic male counterparts, they face an increased risk of suicidal ideation, but they also face more difficulties in peer relationships, academic problems, and increased anxiety and depressive symptoms, but may not get supports. School-age girls spend their days with …

Tubuh Yang Mengingat (The Body Remembers): Ecology, Ritual, And Embodied Memory In Contemporary Cirebon Mask Performance, Prameswari Mrajabwana

Theses and Dissertations

Tubuh yang Mengingat (The Body Remembers) is a single-channel, site-specific performance film set across coastal and extractive landscapes in Cirebon, West Java, Indonesia. Reinterpreting the five transformations of Cirebonese mask dance—Panji, Pamindo, Rumyang, Tumenggung, and Kelana—the project examines how colonial extraction, ecological deterioration, and systems of social regulation continue to shape embodied experience materially and somatically. Drawing from Karen Barad’s concept of intra-action and Stacy Alaimo’s notion of trans-corporeality, the work approaches body, land, technology, and history as relationally entangled rather than separate entities. Through live biodata sonification generated from environmental sensors and bodily movement, the film establishes …

Queer Postsecular Conocimiento: Anzaldúan Readings Of Time, Spirituality, And Transformation In Nugent, Vuong, And Herrera, Joshua A. Swem

Theses and Dissertations

An overreliance on secularism within the field of queer theory and a denial of spiritual epistemologies prevent deep, alternative, and transformative strategies of analyzing literature. It can regurgitate oppressive ideology in academia. In this work, I synthesize Gloria Anzaldúa’s theoretical concepts of mestiza consciousness, nepantla, la facultad, and el cenote with José Esteban Muñoz’s queer temporality and futurity as a framework to engage with literary texts in queer, postsecular ways, freeing up fresh insights and polysemic perspectives. I argue that in  "Smoke, Lilies, and Jade" by Richard Bruce Nugent, Signs Preceding the End of the World by Yuri …
