The Role Of Dust Inputs And Sediment Phosphorus Diffusion Into Utah Lake, Utah, United States Of America, Kristen E. Smith

Theses and Dissertations

Human activities have led to excessive nutrient enrichment which is greater than lake systems can naturally assimilate. This process is known as eutrophication and it is driving significant algae growth resulting in the more common release of harmful toxins. Utah Lake, located in Utah County, UT is one such water body that even after major reductions in anthropogenic phosphorus influent, continues to experience frequent, harmful algal blooms. The extent to which natural processes, like atmospheric dust deposition and sediment recycling, contribute to the lake's phosphorus budget is still poorly understood.

To address this gap of knowledge, this study quantified phosphorus …

Child Maltreatment And Recidivism: Do Maltreatment Patterns Influence General And Violent Reoffending?, Nan Li, Matt Shelton, Elena L. Grigorenko

Psychological Science Faculty Publications

This study examined whether patterns of maltreatment predicted reoffending among 5,194 justice-involved youth (JIY) from a large Texas juvenile probation department. Using latent class analysis on five maltreatment types (physical abuse, emotional abuse, sexual abuse, neglect, and exposure to domestic violence), we empirically identified three classes: “Poly-victimization” (17.8%; high across all types), “Psychological Maltreatment” (15.3%; high emotional abuse and neglect), and “Low Maltreatment” (66.9%; low/moderate across types). JIY in the “Poly-victimization” and “Psychological Maltreatment” classes were more likely to engage in general and violent reoffending within 1 year controlling for covariates. These findings highlight the varying importance of different maltreatment …

Relationship Between Muscle Activation And Kinematic Features During Baseball Pitching, Maxwell Skene

Theses

Background: Baseball pitching is a biomechanically complex, high-velocity movement that places substantial demands on the upper extremity. Inefficient coordination between muscle activation and kinematic sequencing has been associated with reduced performance and increased injury risk, particularly at the shoulder and elbow. However, the integrated relationship between muscle activation patterns and three-dimensional kinematic features during pitching is not well-documented. Purpose: The purpose of this study was to examine the relationship between throwing-arm muscle activation patterns and three-dimensional kinematic characteristics during fastball pitching, with particular emphasis on segmental accelerations, proximal–distal sequencing, and the directional structure of movement quantified using Relative Dimensional Contribution …

Developing Nlp-Based Open-Source Tools To Improve Titratable Infusion Order Interpretation In Ehr Systems, Benjamin Brewer, Jay Dorris

Student Scholar Symposium

This study evaluates the feasibility of using natural language processing (NLP) tools to identify errors in titratable infusion orders for Joint Commission readiness. Titratable infusions are adjusted at the bedside by nurses based on predefined parameters, such as monitoring goals, titration rate, conditions for adjustment, and maximum dose. These parameters are often documented as free text within order sets but can be inadvertently removed during the verification process. Some electronic health records (EHRs) may not prominently display this critical information, leading to potential Joint Commission violations. A synthetic dataset was generated using artificial intelligence to simulate one year’s worth of …

Measuring Welfare Of Wild Tarantulas During Field Surveys Using Heart Rate, Tim Angelo Artiaga Lopez, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Tarantulas (Theraposidae) are predatory arachnids that can help control populations of herbivorous arthropods. We have been monitoring populations of the Missouri brown tarantula (Aphonopelma hentzi) in Missouri glades for three seasons and have questions about their welfare during these surveys. Unlike mammals, arthropods are not extensively researched and there are only a few known facts about measuring their welfare. Managing stress for wild animals during field surveys is important for reducing the potential negative impacts of research. In mammals, increased heart rate is positively correlated with negative stress and eustress. Using the same logic, we hypothesized that heart rate could …

Visualizing And Evaluating Binary Classifier Performance With Contingency Space, Colin D. Kehoe, Azim Ahmadzadeh

Undergraduate Research Symposium

Traditional metrics for evaluating binary classifiers, such as Accuracy, F1 Score, and True Skill Statistic (TSS), often obscure the underlying tradeoffs between true positive and true negative performance—particularly in imbalanced or high-stakes domains. This poster introduces the Contingency Space, a two-dimensional representation of classifier behavior defined by true positive rate (TPR) and true negative rate (TNR). Within this space, scalar performance metrics become geometric surfaces, revealing how scores vary across the entire landscape of possible classifier outputs.

We present a Python package that implements this framework, enabling users to map model predictions into the Contingency Space, visualize metric surfaces …

Habitat Disturbance And Biodiversity In Glade Habitats, Maddie Smith, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

The Ozark glades are home to a variety of reptiles, amphibians, rodents, and invertebrates such as tarantulas and scorpions. Glade inhabitants face challenges like habitat fragmentation and degradation, but they could be facing even bigger challenges as outdoor recreation becomes more popular. People looking for wildlife to photograph or collect often look under rocks without leaving them how they were found. This study focused on monitoring rock disturbance at two protected glades- Shaw Nature Preserve and a more accessible undisclosed glade in Jefferson County. Disturbing the glade habitat to look for wildlife is prohibited at both sites. Twenty rocks at …

Pixel-Perfect Segmentation Of Solar Filaments, Jamie Harris

Undergraduate Research Symposium

The observation and classification of solar filaments has a drastic impact on the ability to predict solar-magnetic weather phenomena that threatens to put both satellite infrastructure and astronauts at risk. Using the Hɑ filter provided by the Global Oscillations Network Group (GONG), a network of six telescopes around the world dedicated to 24/7 surveillance of the sun, we are able to get images that clearly and prominently display filament activity. With the vast amount of images the GONG takes, it is not possible to manually analyze every image. Using the U-Net model for computer vision, we were able to train …

Dying To Belong? The Impact Of Thwarted Belongingness Among Those Who Attempt Suicide In Jail, Dayana R. Escobedo, Mckenzie Wood

The Guardianship Journal

Suicide and attempted suicide remain a major concern in correctional facilities. Jail personnel have developed unique ways of responding to incarcerated individuals who display signs of suicidal ideation, but may be less equipped to identify who may be suicidal upon arrival at the facility. Among potential markers for suicidal behaviors are incarcerated individuals struggling with feelings of thwarted belongingness, or a feeling of disconnection and lack of closeness. Applying a quantitative methodology, this study utilized data obtained from a mid-sized jail in the Mountain West subregion of the Western United States. The data, retrieved from correctional officer reports and intake …

The Equity Dead Zones: Legal Intersectionality Failure Points In Chapter 13 Bankruptcy, Tearria N. Simmons

The Guardianship Journal

Legal intersectionality failure points describe the systemic fractures that occur where overlapping legal, social, and economic inequalities converge, potentially producing compounded barriers to relief. Each failure point marks a site of marginalization. In what ways do individuals already recognized as vulnerable in Chapter 13 bankruptcy face a heightened risk when multiple forms of disadvantage intersect? When these intersections combine in mutually reinforcing ways—racial, economic, and relational disparities colliding with structural deficiencies in family, property, and bankruptcy law—does it result in pronounced negative outcomes, and, if so, what are those outcomes? Within this convergence, could there be a space where compounded …

Influencing The Meteoric Rise Of Ai: Centering Ethics, Law, And Society In Urgent Policy Reform, Erin L. Shah Mspm, Heath A. Clark Mba, Xarlene B. Choi Bs, Garrett K. Chan Phd

The Guardianship Journal

Artificial intelligence (AI) represents a transformative technological advancement with the potential to yield extraordinary societal benefits while simultaneously introducing significant potential harms to individuals, governments, and society. The adoption of AI has outpaced the ability of society to collectively and cohesively respond through the implementation of adequate regulatory guardrails. While AI presents novel benefits and challenges, the broader dynamic of responding to new, uncharted technologies has historical precedence. The article's methodological approach employed empirical research using law articles and policies. As such, the article explores the benefits, challenges, and actual or potential harms in three business sectors: business and finance, …

Engaging Seminars: The Impact Of Storytelling In Public Safety Education, Mimi Gough, Glenn L. Walton

The Guardianship Journal

This paper examines the important role of storytelling in higher education as a technique for engaging students in course content and applies its relationship to the experiential learning theory (ELT) in which learners are actively seeking knowledge through authentic application. Storytelling can be a particularly effective method when used during live online seminars in public safety education, since this particular program of study often relies on verbally communicating realistic and credible information. Sharing various examples of actual encounters can help students better prepare for these types of situations when they face them in their future careers. Incorporating evidence to support …

"Let Your Body Do The Talkin'": An Investigation Of Aesthetic Experience Through Phenomenological Psychology, Tone Roald, Anders Essom-Stenz

Duquesne Studies in Phenomenology

How does the experience of one’s own body contribute to aesthetic experience? This article answers the question from the point of view of phenomenological psychology by portraying how the body is lived from within in intense experiences with works of visual art. Based on descriptions of aesthetic experiences juxtaposed with phenomenological insights about the body and, in particular, Maurice Merleau-Ponty’s thoughts on concrete and abstract movement, it is shown how the lived body gives form to the experience. The experience of one’s own body reflects the expressions of the works of art and comprises not only movement, and with it …

Emotions As Work Material: On Dancers' Refined Use Of Affectivity, Camille S. Buttingsrud

Duquesne Studies in Phenomenology

As part of their professional practice, dancers allow their affectivity to enhance their kinesthetic work. Their intentional and disciplined use of personal, emotional resources ensures both creativity, interpretation, absorption, and connections in ways that extend beyond the traditional phenomenological understanding of affectivity as pre-reflectively based. The affective regulations dancers employ can be seen as an “artistic epoché,” and their layered performance awareness corresponds with Edmund Husserl’s descriptions of “image-consciousness.” Through qualitative interviews with three professional dancers, phenomenological theory, and additional supportive literature, this article shows how affectivity can be experienced through high-order levels of Leib, constituting states of “bodily …

Participatory Presence In Aesthetic Experiences Of Performance, Sophie Morrissey, Shaun Gallagher

Duquesne Studies in Phenomenology

In the context of the performing arts, presence can generally be thought of as an experienced connection between performer and audience that heightens the affective impact of the performance. Explorations of how presence is experienced during live performance contribute to our understanding of the relation of presence to participants’ overall aesthetic experience and participation in the performance. However, they also reveal the complex phenomenology of presence and the challenge of offering a unified framework that can account for its various phenomenal manifestations. In this article, we conceive of presence as a recursive dynamical feedback loop that emerges through and modulates …

With Images In Time. Atmosphere And Art: Mediation And Dialogue, Pauline Von Bonsdorff

Duquesne Studies in Phenomenology

The article challenges the idea that atmospheres are always sensed immediately. Instead, atmospheres in art are mediated and arise in a dialogue between work and audience. To understand how, we should pay attention to temporal structures in and around the work, such as the dynamics and duration of aesthetic experience and the historicity of both work and perceiver, including pasts and present. Mikel Dufrenne’s phenomenological aesthetics, complemented with insights from Maurice Merleau-Ponty’s analyses of perception, offer resources for this. Writing on expression, Dufrenne distinguishes “presence,” in which sense is felt immediately and firmly connected to embodiment, and “sentiment,” which arises …

Rapture "At A Distance": Searching For Pathic-Atmospheric Aesthetics, Tonino Griffero

Duquesne Studies in Phenomenology

The paper proposes a rethinking of the role of aesthetics as a theory of sensory experience as it is encountered in the lifeworld (and only secondarily in relation to art). Accordingly, pathic and atmospheric (bottom-up) aesthetics, which centers on the ability to expose oneself to intense experiences without attempting to control them and conceives feelings as atmospheric powers that permeate a particular space without being reduced to projections of the perceiver’s moods, should replace the idealistic (top-down) approach.

Ted Cruz, Tucker Carlson, And The 'Terrorists' Of January 6th: Mortification, Groveling, And Political Image Repair Discourse, Matthew Gerber, Kayla Rhidenour

Speaker & Gavel

This article examines the image repair discourse of Senator Ted Cruz (R-TX) as it relates to an incident that occurred on the Tucker Carlson Tonight show following the events of January 6th, 2021, at the U.S. Capitol. After referring to the January 6th rioters as “terrorists”, which angered his Republican base, Cruz was compelled to appear on Carlson’s highly watched Fox News program in an attempt to bolster his reputation. The authors argue that Cruz’s strategic approach is best classified as mortification, but also note and investigate the nonverbal, tonal, and extra-message influence of groveling as it played out in …
