Optimizing Ucs Prediction Models Through Xai-Based Feature Selection In Soil Stabilization, Ahmed Mohammed Awad Mohammed, Omayma Husain, Mosab Hamdan, Abdalmomen Mohammed, Abdullah Ansari, Atef Badr, Abubakar Elsafi, Abubakr Siddig

Research Outputs: 2025-Present

Unconfined Compressive Strength (UCS) is a key parameter for the assessment of the stability and performance of stabilized soils, yet traditional laboratory testing is both time and resource intensive. In this study, an interpretable machine learning approach to UCS prediction is presented, pairing five models (Random Forest (RF), Gradient Boosting (GB), Extreme Gradient Boosting (XGB), CatBoost, and K-Nearest Neighbors (KNN)) with SHapley Additive exPlanations (SHAP) for enhanced interpretability and to guide feature removal. A complete dataset of 12 geotechnical and chemical parameters, i.e., Atterberg limits, compaction properties, stabilizer chemistry, dosage, curing time, was used to train and test the models. …

Why Does The U.S. Still Practice The Death Penalty? An Application Of Waltz's Three Images, Anika Tracy

University Honors Program Senior Projects

The United States is the only Western democracy that still practices the death penalty, and legal scholars, domestic politics scholars, and comparativists have written extensively about American capital punishment. In this thesis, I will synthesize this scholarship to present a multifaceted explanation for America’s uniquely continued use of the death penalty through Kenneth Waltz’s three “images” or levels of analysis. While Waltz’s three levels of analysis is an established theory in the field of international relations (IR), the utilization of IR theory for an analysis of American capital punishment is particularly enriching because death penalty abolition is a norm in …

Leveling The Playing Field: The Atlantic Coast Conference’S Settlement With Florida State University And Clemson University, Emma Lloyd Best, Kyre Dane Lahtinen

Fordham Intellectual Property, Media and Entertainment Law Journal

This Article examines the legal disputes and subsequent settlement between the Atlantic Coast Conference and two of its prominent member institutions, Florida State University and Clemson University. The conflicts centered on the Atlantic Coast Conference’s extension of its media rights agreement with ESPN, which both universities argued were not properly approved under conference bylaws and imposed an unconscionable withdrawal penalty. Florida State University sought to challenge the enforceability of the Grant of Rights and its associated penalties, while Clemson University pursued a narrower interpretation, aiming to limit broadcast rights and financial obligations upon exit. The …

A Third Possibility: The Press Clause At The Founding, Matthew L. Schafer

Fordham Intellectual Property, Media and Entertainment Law Journal

With the rise of history and tradition at the Supreme Court, scholarship purporting to define historical fact is likely to have outsized influence on the development of constitutional law. Underdeveloped constitutional rights like the First Amendment’s Press Clause are especially susceptible to such influence as they lack a precedential counterweight. While Press Clause jurisprudence is shallow, historical research about the Press Clause is not. For decades, scholars who have considered the Press Clause’s historical meaning have generally concluded that the record is quite vague, and, for that reason, cautioned against absolutist conclusions as to its original understanding. …

Deregulating The Song: The Case For Free- Market Licensing Of Musical Works In The Digital Streaming Era, Bailey Alberton

Fordham Intellectual Property, Media and Entertainment Law Journal

This Note takes as its starting point that songwriters are inadequately and unfairly compensated for the streaming of their music and argues that the unique and pervasive government regulation of musical composition licensing exacerbates this problem. To address this problem, this Note argues that both the compulsory mechanical license and the performing rights organizations consent decrees should undergo reform to permit songwriters to negotiate with music streaming services in the free market.

Making Three Dimensional Constellations, Larry Browning, Kay Cutler

Astronomy Activities

We look up at the night sky to find constellations or patterns in the stars and associate images and stories with these patterns to help remember the pattern and follow its motion through time. Often each culture has its own constellations with stories or folklore about each constellation.  These stories are a window into the experiences, activities, beliefs, and location of the people who named their culture’s star patterns.  Traditional star patterns are based on naked eye observations since these constellations were determined before telescopes or binoculars.

Brightness And Distance Of The Stars: Joly Photometer, Larry Browning, Kay Cutler

Astronomy Activities

How bright a star appears to an observer on earth and what color or colors make up its light can tell a lot about a star. The brightness offers a clue to how far away a star is. The color indicates how hot the star is. Together they may suggest the size of a star. Examining the details of the star light with a spectroscope shows the various colors that come from the star and indicates the very specific colors that are muted or missing, as well as those that are brighter than expected (absorption and emission spectra). This gives …

Solar And Lunar Eclipse Model, Larry Browning, Kay Cutler

Astronomy Activities

Match Or Mismatch? : The Effects Of Fingerprint Evidence And Expert Testimony On Jury Decisions, Kassie N. Thallas

Dissertations

Fingerprint evidence is widely perceived as objective and reliable, yet is typically presented to jurors through expert testimony rather than directly evaluated. The present study examined how fingerprint match status and expert testimony influence juror decision-making. Participants (N = 225) read a mock criminal trial summary and were randomly assigned to one of five conditions. Four conditions were derived by crossing Expert Condition (fingerprint expert alone vs. conflicting experts) and Match Status (match vs. no match), with an additional control condition without fingerprint evidence. The participants made verdict decisions and rated the credibility, honesty and believability of the expert. The …

Exploring Detached Concern, A Dual-Process Emotional-Regulation Strategy, Among Intensive Care Nurses Providing End-Of-Life Care In The United States, Melissa Milton Miasek

Dissertations

Intensive care unit (ICU) nurses repeatedly provide end-of-life care (EoLC) and experience significant emotional distress, burnout, and moral distress that can lead to leaving the profession. Detached concern (DC), a dual-process emotional-regulation strategy which balances empathetic concern with emotional detachment, may support ICU nurses' emotional well-being; however, DC among nurses remains vastly understudied. This qualitative descriptive study gained deeper understanding of DC among ICU nurses providing EoLC in the United States. The study was guided by a conceptual model adapting Lampert and Glaser's dynamic DC process within Elfenbein's emotional regulation framework. The overarching research question explored ICU nurses' perspectives on …

A Computational Investigation Of The Deposition Of Firebrands Subject To A Turbulent Jet Flow, Patrick Wayne Damiani

Dissertations

To improve the understanding of the role of firebrands in fire spread, the dispersion and deposition of firebrands carried by turbulent jet flows were simulated by Lagrangian particle tracking and large--eddy simulation. The simulations were configured to replicate previous experiments involving cubiform and cylindrical particles carried by pipe flow and the resulting jet flow before deposition on the ground. First, validations were performed for the jet flow simulations by comparing quantities such as the jet spread rate and velocity decay constant with previous experimental and theoretical values for free jet flows. Then, two series of simulations were performed to evaluate …

Comprehending Levels Of Explainability And Ai Recommendations (Clear) Study Series, Virginia Sullivan

Dissertations

AI systems can offer a great deal to improve decision-making through efficiency and predictive accuracy due to their unique ability to rapidly analyze large amounts of data relevant to the decision. Yet many AI systems remain opaque, limiting users’ ability to evaluate outputs and leading to issues of mistrust or over-reliance. This dissertation investigates how varying levels of AI explainability affect trust, perceived reliability, understanding, and confidence, and identifies perceptual and behavioral indicators of over-reliance behavior in AI-assisted decision making scenarios. This dissertation is organized as a three-study series. The CLEAR survey study uses a mixed design to examine the …

Off-Label Abuse: The Prosecution Of Individuals For Pesticide Crimes Under The Federal Insecticide, Fungicide, And Rodenticide Act, Joshua Ozymy, Melissa Jarrell Ozymy

Natural Resources Journal

When individuals commit pesticide crimes involving significant harm or culpable conduct, they may be prosecuted for criminal violations of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), but we have little knowledge of how individual offenders have been prosecuted historically for such crimes. Using content analysis of 2,728 environmental crime prosecutions resulting from U.S. EPA criminal investigations, 1983 to 2021, we select all cases of individuals prosecuted under FIFRA for our analysis. We find that 100 cases were adjudicated, resulting in 135 years of probation, 75 years of incarceration, and $4.2 million in monetary penalties assessed at sentencing. Of those …

Expanding The Boundaries Of Bedside Practice: Transport Nursing As A Living Model Of Clinical Nurse Specialist Competencies, Ian A. Lane

Faculty Publications (Peer-Reviewed)

Objectives: The purpose of this paper is to argue that clinical nurse specialist (CNS) education represents the most conceptually and professionally continuous advanced practice pathway for critical care transport nurses, and to highlight transport nursing as an underrecognized practice context that aligns closely with CNS competencies and warrants deliberate attention from CNS educators and programs.

Description:  This paper presents a conceptual analysis of transport nursing through the CNS spheres of influence, emphasizing continuity with bedside nursing expertise while extending into quality improvement and systems leadership. This perspective examines how transport nurses routinely navigate high-acuity clinical cases and interfacility system constraints. …

An Anti-Adhesive Compound Modulating The Production Of Staphylococcus Aureus Cell Wall-Anchored Proteins, Allison C. Leonard, Ruina Bao, Cindy Menjivar, Megan J. Myers, Telmo O. Paiva, Zhiyong Zheng, Kirsten A. Berry, Kenneth W. Bayles, Ronald S. Flannagan, Yves F. Dufrêne, Jeffrey L. Bose, David E. Heinrichs, Georgina Cox

Journal Articles: Pathology and Microbiology

As one of the leading global causes of death associated with antimicrobial resistance, Staphylococcus aureus frequently colonizes the human nasal cavity and adheres to keratinized skin, establishing reservoirs that drive subsequent infections and emphasize the need for new decolonization strategies. Using a high-throughput, whole-cell screening platform, here we identify geranylgeranoic acid (GGA), a naturally occurring polyunsaturated, branched-chain fatty acid, as having dual activity against methicillin-resistant S. aureus (MRSA). At elevated concentrations, GGA exhibits microbicidal effects, whereas at sub‑microbicidal doses, it effectively inhibits MRSA adhesion to keratin, fibronectin, fibrinogen, and immunoglobulins. GGA possesses anti-adhesive activity against a panel of multidrug-resistant S. …

Examining Connections Between Therapist Self-Disclosure, The Therapeutic Relationship, And Cultural Mistrust In A Sample Of Black And White Emerging Adults, Sarah Mitty Mcnamee

Selected Full-Text Dissertations 2020-

This analogue study examined how two different types of therapist self-disclosure (TSD) influenced the assessment of the working alliance and real relationship by observer participants, and how these variables were impacted by a participant’s race and experience of cultural mistrust. A sample of N = 339 Black and White adults watched one of two mock therapy videos, depicting either a non-immediate TSD or an Alliance- Focused Training (AFT)-consistent immediate TSD in response to the patient’s rupture markers. Based on the video, each with the same White therapist and bi-racial patient, participants rated the observed working alliance and real relationship. Participants …

Factors Affecting Detection Of A Cryptic Ambush Predator Using Camera Traps, With Implications For Snake Monitoring, Sarah Elizabeth Ebert

Theses, Dissertations and Capstones

Camera traps are becoming increasingly popular in wildlife research because they can be deployed for long time periods with little maintenance and are much less invasive than traditional trapping methods. However, they are primarily used to study large mammals and have not been extensively tested for snake species, many of which are cryptic and understudied. The Adapted-Hunt Drift Fence Technique (AHDriFT) arrays were designed to improve detection of herpetofauna by attaching camera traps to drift fences. In the summer of 2022, we installed 20 AHDriFT arrays at the Marine Corps Recruit Depot Parris Island in coastal South Carolina where we …

Climate, Energy, Economy: Interconnected Perspectives From Politics, Business, And The Public, Isabella Harper Heinzen

Theses and Dissertations

When considering the economic and social costs and benefits of a global, intergenerational, and environmental issue, rigid analysis often falls short. The topics discussed in this thesis aim to address the complex moral, economic, and political concerns regarding climate change to provide a holistic view of the issue and the role humans play. The first section on the scientific consensus addresses concerns regarding the existence and severity of climate change, finding where the responsibility lies for humans. The second section analyzes the energy context in modern society to understand the call for a transition from oil and gas to renewable …

African American Women’S Engagement In The Black Liberation Struggle At Home And Abroad 1910-1977, Ryhaan Ameena Shakoor

Theses and Dissertations

This dissertation studies the major social and political events of the twentieth century as seen through the eyes of seven African American women, Mary Church Terrell, Amy Jacques Garvey, Claudia Jones, Salaria Kea, Eslanda Robeson, Maida Springer and Shirley Graham Du Bois. It brings to light the significance of their efforts in the fight against racism, fascism, colonialism, apartheid and neo-colonialism in the United States and abroad. As the history of the Black liberation struggle was mostly dominated by male historians and writers, this work demonstrates that amongst others, these seven African American women made gender an important component to …

Applying Groupthink To Digital Spaces: The Rise Of Online Conspiracy Theory Networks, Lily Karen Schow

Theses and Dissertations

This thesis examines the transformation of political paranoia and collective decision-making in the United States from the twentieth century to the digital age. Building on Richard Hofstadter’s concept of the “paranoid style” and Irving Janis’s theory of groupthink, it argues that the dynamics of conspiratorial thinking and collective misjudgment have not disappeared but have been reconfigured by digital communication systems. While Hofstadter identified paranoia as a recurring rhetorical mode and Janis analyzed groupthink as a pathology of small, cohesive decision-making groups, this study contends that both frameworks require adaptation to account for contemporary digital environments. The analysis traces how historical …

Understanding Self And Others: Exploring The Relationship Between Maladaptive Personality Traits And Theory Of Mind, Christian Dellavella

Theses and Dissertations

The relationship between theory of mind (ToM) and maladaptive personality traits is a poorly understood but critical intersection between cognitive and clinical psychology. While some research has suggested certain personality characteristics may elevate ToM ability, others may contribute to deficits that lead to negative health outcomes and poor social functioning. Understanding how variability in the population’s ideological disposition affects our capacity to comprehend others’ perspectives and emotions is key to grasping the intricacies of social interactions. As the fields of clinical psychology and psychiatry begin to reclassify their diagnostic systems, it is critical to evaluate how novel conceptualizations of personality …

A Hero’S Horizon Of Mirrors: Dovette, Deve, Dovrà, William James Kerrane

Theses and Dissertations

This dissertation examines James Joyce’s Ulysses as a modern transformation of the Ulysses myth through the philosophical framework of Ernst Cassirer’s theory of symbolic forms and W.B. Stanford’s historical study of the Ulysses tradition. While Stanford demonstrates how the figure of Ulysses has been continually reinterpreted across literary history—from Homer’s cunning hero to Dante’s transgressive explorer and the restless modern figures of the nineteenth century— this study argues that Joyce’s Ulysses represents a uniquely philosophical adaptation of the myth in which heroic identity becomes a function of symbolic consciousness rather than physical action. Drawing on Cassirer’s philosophy, which defines myth, …

Examining Positive Psychology Components In Cbt For Adolescent Depression: A Manual-Level Content Analysis, Isabel Bingham Mixter

Theses and Dissertations

Adolescent depression is prevalent, recurrent, and associated with substantial functional impairment, yet variability in treatment response suggests that existing interventions may differ in how therapeutic processes are emphasized. The present study examined the extent to which positive psychology–consistent components, operationalized using the PERMA framework (positive emotion, engagement, relationships, meaning, and accomplishment), are embedded within empirically supported cognitive-behavioral therapy (CBT) manuals for adolescent depression and whether variation in this content corresponds to differences in treatment outcomes. Rather than analyzing individual participants, the unit of analysis was the treatment manual. Seven manualized CBT protocols for adolescents aged approximately 12–17 years were identified …

Academic Attention And Executive Difficulties In College Students: Reliability, Convergent Validity, And Exploratory Associations With Gpa, Piotr Draus

Theses and Dissertations

Attention-Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterized by difficulties in attention regulation, organization, and impulse control, which may be associated with academic challenges in higher education settings. The present study evaluates a custom, non-diagnostic academic attention/executive difficulties composite developed for college students and explores its associations with academic performance. Student participants (N=56) completed an online survey that included the custom composite, the Adult ADHD Self-report Scale (ASRS v1.1), and a self-reported numeric grade point average (GPA). The study primarily examined internal consistency and convergent validity of the custom composite using the ASRS v1.1 and secondarily explored associations between …

Parental Emotion Regulation: Associations With Child Affect And Emotion Socialization Behaviors, Jordan Holmén

Theses and Dissertations

Parenting is an emotional context in which parents often need to be able to regulate their own emotions in order to respond effectively to their child. Thus, how one regulates themselves may impact child outcomes. Supporting this notion, parent emotional regulation (ER) has been found to influence child adjustment (for a review, see Zimmer-Gembeck et al., 2021) and, more specifically, child affect (Hamzallari et al., 2022). For example, maternal suppression of emotions has been found to predict infant frustration (i.e., crying; Hamzallari et al., 2022). However, it is less clear how parent ER impacts child positive and negative affect. Theory …

The Burden Of (Hand)Writing: The Lived Experiences Of Secondary Students With Dysgraphia, Eleesha S. Romasko

Theses and Dissertations

Developmental dysgraphia is a disability that impacts the writing of students and has long-term effects on their education. While past research has primarily focused on clinical aspects, there is scarce qualitative research. The purpose of this study was to give a voice to the experiences of secondary students (grades 6-12) with dysgraphia using a phenomenological approach. The study was grounded in Piaget’s cognitive constructivism and uses a Heideggerian hermeneutic phenomenological approach to understand the lived experience of students with dysgraphia. The research utilized purposive sampling to find four participants with dysgraphia who were in grades 6-12. Data was collected through …
