Is “No Change” Really No Change?: A Qualitative Analysis Of Clients With “No Change” On Routine Outcome Monitoring Who Report Improving In Therapy, Audrey Louise Stewart Parker

Theses and Dissertations

Routine outcome monitoring (ROM), the practice of tracking client progress in therapy by administering regular questionnaires to assess functioning, has demonstrated a significant positive effect on psychotherapy outcomes, especially for clients are who not improving as expected. However, some researchers argue the symptom-based measures and outcome classification criteria commonly used in ROM may not represent a complete picture of client change. A recent body of mixed-methods research has investigated these ROM-determined outcome categories to gain insight into client experiences and whether the category and client perception of therapy outcome align. In this investigation, researchers have found significant variety within outcome …

Modifying Lta Zeolites For Reversible Hydrogen Sulfide Capture And Elucidating The Structure Of The Incorporated Metal And Sulfur Ions, Adeyemi D. Ojaide

While Linde Type A (LTA) zeolites offer a robust structural framework for gas separation, a comprehensive understanding of how …

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, …

Analyzing The Transition From Writing Center Tutor To Graduate Student Instructor, Luci Mackenzie Sullivan

Theses and Dissertations

Writing center tutoring is almost universally considered to be beneficial preparation for graduate student instructors (GSIs) of writing, so much so that many programs require writing center experience as part of their GSI training. Despite various similarities between the roles of tutor and teacher, the precise ways in which writing center experience influences GSIs as teachers remain unclear. This IRB-approved, mixed-methods study builds on previous empirical scholarship on transfer between tutoring and teaching to determine how new GSIs with previous writing center experience integrate practices, knowledge, and dispositions developed in the writing center. My findings echo those of previous studies …

A Graphical Approach To Isospectral Unfoldings, Dallin Seyfried

Theses and Dissertations

Isospectral reductions are mathematical techniques used to shrink a matrix, or a graph, into a smaller, dimensionally reduced form while preserving its spectrum. Simple graphs that share isospectral reductions also share quantum walk properties. As such we further develop the inverse process, isospectral unfoldings, to find graphs that share isospectral reductions. We first prove many conditions relating to isospectral reductions and unfoldings. Afterwards, we define two new unfolding processes: general unfolding which unfolds the graph one vertex at a time, and equitable partition unfolding which excels at larger graph unfolding. In particular, through equitable partition unfolding, we discover many graphs …

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 …

Sand Distribution On Titan And Implications For Sand Transport And Interconnectedness Of Sand Seas, Delaney Rose

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

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 …
