Mathematical Logic And Computer Language, Yueun Park

SACAD: Scholarly Activities

Fundamental principles of computer programming comes from mathematical logic. Mathematics enables programming languages to interpret and execute complex instructions. This project explores the possible application of mathematical logic within programming languages by developing a Boolean logic calculator in C++. The program implements a stack-based algorithm to convert infix notation (which we often use) to postfix notation (which computers can evaluate) and uses subsequent functions to evaluate the postfix notation. The program focuses on logic operators NOT, AND, and OR, classified with specific precedence hierarchies. Program analysis shows that the processes have linear time complexity, that is, O(n). The result suggests …

Application Identification With Pfsense, Snort, And Openappid In Academic Lab Networks, Minh-Khanh Vu

Journal of Cybersecurity Education, Research and Practice

This paper evaluates the practical capabilities and limitations of a widely used open-source network security stack—pfSense firewall, Snort Intrusion Detection System (IDS), and OpenAppID detectors—in academic cy- bersecurity laboratories and small-to-medium enterprise (SME)-like environments. In a controlled virtual testbed, we measure application-level and feature-level identifi- cation performance for major applications (Facebook, YouTube, Zoom) using the pfSense/Snort/OpenAppID configuration. The stack achieves 97% application-level identification accuracy for these applications in our lab dataset, drawing on a library of 3,374 OpenAppID detectors. However, our experiments reveal a substan- tial feature-level detection gap: specific functions such as Zoom file transfers and Facebook messaging can- …

Hidradenitis Supprativa: Communication Strategies To Improve Awareness And Reduce Stigma, Temilade Adewale

Theses

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition associated with significant physical and psychosocial burden. Despite increasing clinical recognition, patients frequently experience diagnostic delays, stigma, and inadequate communication with healthcare providers. The purpose of this study was to examine communication patterns surrounding HS and explore how these patterns relate to stigma, misinformation, and patient experiences. This study used a qualitative design incorporating a structured literature review and semi-structured interviews with 85 participants. The Narrative Paradigm guided analysis, focusing on how individuals construct meaning through their experiences and interactions. Thematic analysis identified key patterns in patient-provider communication, misinformation exposure, and …

Competition As A Solution To High Prices And Low Capacity In U.S. Healthcare: A Synthetic Control Analysis Of Certificate Of Need Repeal As A Lever For Hospital Market Reform, Eve Velasquez, Wyatt Greco

School of Public Policy Capstones

The U.S. healthcare system faces dual challenges: rising hospital prices and declining capacity. Between 2000 and 2024, average hospital expenses per adjusted inpatient day increased from approximately $1,000 to over $3,000, while hospital beds per capita declined from 3.11 to 2.45. This capstone evaluates three policy alternatives to address affordability and accessibility: restrictions on most-favored nation clauses in insurance-provider contracts, elimination of federal tax exemptions on employer-sponsored health insurance, and repeal of certificate of need (CON) laws. Through a comprehensive literature review and a synthetic control analysis of Indiana's 2019 nursing home CON reinstatement, we assess the empirical effects on …

Advanced Machine Learning Approaches For Bankruptcy Prediction In The Shipping Industry: A Comparative Analysis Across Time Horizons, Minchul Sohn, Saeyeon Roh, Minsu Kwon

Plymouth Business School

This study evaluates machine learning methods for predicting bankruptcies in the Korean shipping industry over 1-, 3-, and 5-year horizons. Using an imbalanced dataset, preprocessing techniques such as outlier capping, skewness correction, and SMOTE-based oversampling are applied. Two feature sets—financial variables and those enriched with macroeconomic and shipping indicators—are analyzed. Results demonstrate that ensemble methods like LightGBM, CatBoost, XGBoost outperform linear models and deep neural networks across all horizons. Short-term predictions are driven by liquidity factors, while long-term forecasts benefit from shipping-specific indices like freight rates. SHAP‐based analysis reveals that internal cash‐flow as critical for one‐year predictions, whereas prolonged freight …

Mental Models Of Autonomy And Sentience Shape Reactions To Ai, Janet V.T. Pauketat, Daniel Burton Shank, Aikaterina Manoli, Jacy Reese Anthis

Psychological Science Faculty Research & Creative Works

Narratives about artificial intelligence (AI) entangle autonomy, the capacity to self-govern, with sentience, the capacity to sense and feel. AI agents that perform tasks autonomously and companions that recognize and express emotions may activate mental models of autonomy and sentience, respectively, provoking distinct reactions. To examine this possibility, we conducted three pilot studies (N = 374) and four preregistered vignette experiments describing an AI as autonomous, sentient, both, or neither (N = 2,702). Activating a mental model of sentience increased general mind perception (cognition and emotion) and moral consideration more than autonomy, but autonomy increased perceived threat more than sentience. …

Negotiating Digital Identities With Ai Companions: Motivations, Strategies, And Emotional Outcomes, Renkai Ma, Shuo Niu, Lingyao Li, Alexander Hirth, Ava Brehm, Rowajana Behterin Barbie

Computer Science

AI companions enable deep emotional relationships by engaging a user's sense of identity, but they also pose risks like unhealthy emotional dependence. Mitigating these risks requires first understanding the underlying process of identity construction and negotiation with AI companions. Focusing on Character.AI (C.AI), a popular AI companion, we conducted an LLM-assisted thematic analysis of 22,374 online discussions on its subreddit. Using Identity Negotiation Theory as an analytical lens, we identified a three-stage process: 1) five user motivations; 2) an identity negotiation process involving three communication expectations and four identity co-construction strategies; and 3) three emotional outcomes. Our findings surface the …

Creating Disability Story Videos With Generative Ai: Motivation, Expression, And Sharing, Shuo Niu, Dylan Clements, Hyungsin Kim

Computer Science

Generative AI (GenAI) is both promising and challenging in supporting people with disabilities (PwDs) in creating stories about disability. GenAI can reduce barriers to media production and inspire the creativity of PwDs, but it may also introduce biases and imperfections that hinder its adoption for personal expression. In this research, we examine how nine PwD from a disability advocacy group used GenAI to create videos sharing their disability experiences. Grounded in digital storytelling theory, we explore the motivations, expression, and sharing of PwD-created GenAI story videos. We conclude with a framework of momentous depiction, which highlights four core affordances of …

The Future Of Dual Immersion In California: Analyzing California’S Global 2030 Goals, Jonathan Tejeda, Kamila Campos, Robert Emmans

School of Public Policy Capstones

California's Global 2030 initiative set an ambitious target: half of all K-12 students to achieve bilingual proficiency by 2030. This qualitative study examines whether Dual Language programs (DLPs) in California's major metropolitan areas are positioned to meet that goal. Drawing on ten semi-structured expert interviews with researchers, administrators, teachers, and nonprofit advocates, the study identifies four central challenges: inadequate student preparedness, chronic underfunding, insufficient teacher training, and a failure to connect students to their cultural heritage. The findings reveal that California lacks the infrastructure, data systems, and financial commitment necessary to achieve the 2030 goals. The authors recommend establishing a …

Urban And Suburban Teachers’ Perceptions Of Burnout In The Post-Covid19 Era: A Mixed Methods Dissertation In Education, Dylan Rossin

Graduate Theses & Dissertations

The Covid-19 pandemic fundamentally altered the professional demands placed on K–12 teachers, intensifying concerns related to occupational burnout. This mixed-methods study examined urban and suburban public school teachers’ perceptions of burnout in the post–Covid-19 era, with particular attention to emotional exhaustion, depersonalization, and personal accomplishment. Grounded in Maslach’s theory of burnout, the study sought to determine whether differences existed between urban and suburban teachers’ burnout experiences and to explore educators’ perspectives on factors contributing to burnout following the pandemic.

Participants included full-time public K–12 teachers in Pennsylvania with a minimum of three years of teaching experience. Quantitative data were collected …

Application Of Fidic Epc/Turnkey Contract Under The Egyptian Public Works Contracts Law, Ahmed Alhady Dr., Mahmoud Mahmoud Ahmed Eng., Ahmed Elhakeem Prof., Mohamed Ibrahim Dr.

Civil Engineering

This study focuses on the application of FIDIC Conditions of Contract for EPC Turnkey Projects—Silver Book 1999, (FIDIC (EPC&T)), when governed by the Egyptian Law of Contracts concluded by public bodies No. 182 of 2018 (ELC) due to the conflicts that may arise from such application. Hence, this study identifies specific FIDIC (EPC&T) 1999 clauses that have the potential for conflicts with ELC, shows the similarities and disparities between these clauses and the relevant ELC articles, and provides recommendations to ensure the successful application of FIDIC (EPC&T) 1999 under ELC. This was achieved through a multistep research methodology in which …

Leveraging River Forecast Center Knowledge To Improve Large-Scale Hydrologic Model Performance Through Bias Correction, Ian Mathews

Theses and Dissertations

The National Water Model (NWM) provides continental-scale streamflow predictions but exhibits bias and reduced skill in highly regulated and snow-driven basins. In contrast, River Forecast Center (RFC) models incorporate decades of local calibration and regulatory knowledge but are limited in spatial coverage to specific points of interest. This study evaluates whether hydrologic knowledge embedded in RFC-calibrated simulations can be transferred to improve NWM performance at unmonitored locations using the Streamflow Analysis for Bias Estimation and Reduction (SABER) framework. Using Colorado Basin River Forecast Center (CBRFC) simulations as surrogate reference data, we applied SABER to the NWM 44-year retrospective model simulation …

Health Data And Policy Related To Methamphetamine-Use Suicide In Mississippi, Mary C. Drane

Honors Theses

The purpose of this research is to investigate how methamphetamine use in Mississippi, especially in its rural areas, intersects with public health, policy, and suicide outcomes in the state. Mississippi's methamphetamine crisis has evolved significantly, shifting from locally produced drugs to cartel-supplied crystal methamphetamine, while state and federal policies have struggled to keep pace with the scale and complexity of the problem. Using a convergent parallel mixed-methods design, this research analyzed CDC Wonder multiple causes of death data and SAMHSA Treatment Episode Data Set Admissions (TEDS-A) data from 2018 to 2024 alongside four qualitative key informant interviews with stakeholders across …

A Revolution Of Rational Civility, Honorable Douglas S. Lang

St. Mary's Journal on Legal Malpractice & Ethics

This Article addresses a blind spot in the theorizing and debate over originalist interpretation: the implications of rules of legal ethics.  For the few originalist theorists who take the practical side of originalism seriously, attorneys’ rules of professional conduct are almost entirely absent from the discussion.  Incivility is at epidemic proportions in our society.  That condition is unacceptable.

This Article argues for each of us, lawyers and everyone in all walks of life, to take action and not merely offer lip service to push back against incivility.  We must repel incivility.  This “push back” is not compelled alone by written …

English By Any Other Variety, Leya Shekanena

Masters Projects

African American Language (AAL) is a variety of English that is commonly used and linguistically respected, yet its application is barred from writing courses in higher education. Because AAL’s academic stigmatization negatively impacts the students who utilize AAL, it is important to discover how accepted usage influences students’ understanding of collegiate academic writing and their own identity. To engage with this complex problem, this project integrates Culturally Relevant Teaching and Black Linguistic Justice frameworks with the andragogical method of experiential learning to create a Supplemental Writing Skills college course. The purpose of this course is to explore how encouraged usage …

Epistemic Pluralism, Open Inquiry, And Constructive Disagreement: Strengthening The 2029 Epas, Nafees Alam, Mary K. Twis, David R. Hodge, Naomi Farber, Pilar Horner, Heidi A. Rueda, Vicki Lens, Brett Drake

Social Work Faculty Publications

The Educational Policy and Accreditation Standards (EPAS) of the Council on Social Work Education (CSWE, 2026) shape not only curriculum and assessment, but also the intellectual formation and culture of the social work profession. As the accrediting framework for programs across the United States, the EPAS articulate the definition of competent practice and what constitutes a shared professional identity (Zuchowski, 2024). Yet accreditation standards necessarily do more than articulate competencies; they can also shape which perspectives are institutionally centered and normalized (Sue, 2010). Professional education operates not only through explicit curricular content, but through implicit norms governing what questions may …

The Promises And Perils Of Using Llms For Effective Public Services, Erina Seh-Young Moon, Matthew Tamura, Angelina Zhai, Nuzaira Habib, Behnaz Shirazi, Altaf Kassam, Devansh Saxena, Shion Guha

Health Services and Informatics Research

Governments are the primary providers of essential public services and are responsible for delivering them effectively. In high-stakes decision-making domains such as child welfare (CW), agencies must protect children without unnecessarily prolonging a family’s engagement with the system. With growing optimism around AI, governments are pushing for its integration but concerns regarding feasibility and harms remain. Through collaborations with a large Canadian CW agency, we examined how LocalLLM and BERTopic models can track CW case progress. We demonstrate how the tools can potentially assist workers in opportunistically addressing gaps in their work by signaling case progress/deviations. And yet, we also …

Three-Dimensional Imaging Of Neuronal Activation Patterns In Chronic Neuropathic Pain And Opioid Pharmacology, Madeline Martinez

Electronic Theses and Dissertations 2020 - Present

Chronic neuropathic pain severely diminishes quality of life, yet the supraspinal neural circuits that sustain pain perception and mediate analgesic relief remain incompletely characterized. While peripheral and spinal pain pathways are well established, relatively few studies have mapped pain- or opioid-related neuronal activation across the entire brain. This dissertation employed activity-dependent genetic labeling (TRAP2/Ai9), whole-brain tissue clearing, light sheet microscopy, and graph-theoretic network analysis to characterize brain-wide activation patterns across chronic pain and analgesic conditions in mice.

In Chapter 1, we mapped supraspinal neuronal activation in a bilateral spared nerve injury model of chronic neuropathic pain. Although no individual region …

Navigating Diagnostic Ambiguity In Palliative Pediatric Neuro-Oncology: A Conceptual Framework For Suspected Shunt Malfunction And Refractory Hyponatremia, Olivia R. Kaufman, Samira R. Haberman, Christopher M. Ahmad, Miriana Youkhana

Student Publications

Management of suspected shunt malfunction in pediatric patients with terminal brain tumors presents a complex clinical and ethical dilemma. Differentiating mechanical shunt failure from disease progression or metabolic derangement is often radiographically indeterminate, while invasive diagnostics may conflict with palliative goals of care. We present the case of a five-year-old male with relapsed medulloblastoma and cerebrospinal fluid (CSF) dissemination who developed progressive ventriculomegaly and refractory hyponatremia (serum sodium nadir: 120 mEq/L). The clinical course was complicated by the overlap of potential etiologies: shunt failure, syndrome of inappropriate antidiuretic hormone secretion (SIADH) versus cerebral salt wasting (CSW), and terminal disease progression. …

Characterizing User-Reported Risks Across Llm Chatbots, Lingyao Li, Renkai Ma, Zhaoqian Xue, Junjie Xiong

Computer Science Faculty Research & Creative Works

As Large Language Models (LLMs) become increasingly integral to daily life, users are engaging with multiple LLM chatbots for various needs; however, prior research on LLM risks often remains lab-based or focuses on single LLMs like ChatGPT or singular risks like privacy. To gain a multi-risk, cross-chatbot understanding of user experiences, we analyze Reddit discussions around seven major LLM chatbots using the NIST AI Risk Management Framework. We find that user-reported risks are unevenly distributed and chatbot-specific: ChatGPT is associated with safety and fairness concerns, Gemini with privacy, and Claude with security and resilience. Less frequent risks, such as explainability …

Brief Of The American Immigration Lawyers Association And Immigration Law Scholars As Amici Curiae In Support Of Respondents, Lindsay Nash

Amicus Briefs

Amicus curiae brief submitted by the American Immigration Lawyers Association and immigration law scholars in support of the respondents in Mullin v. Doe and Trump v. Miot before the Supreme Court of the United States. The brief argues that the Temporary Protected Status (TPS) statute strictly limits the Executive Branch's authority to terminate TPS designations and requires continuation of protection unless the statutory conditions justifying designation no longer exist. The amici further contend that TPS serves a critical humanitarian function by protecting individuals from removal, detention, and loss of work authorization while conditions in designated countries remain unsafe.

Exploring Perspectives Of Autistic Individuals And Caregivers On Autism Inclusive Services In Public Libraries, Ayva J. Rose

LSU Master's Theses

Public libraries are increasingly recognized as important community hubs designed to promote literacy, learning, language, family engagement, and inclusivity. Despite this, autistic individuals may experience language, literacy, sensory, and social differences that could impact their ability to participate in literacy-based programming in libraries. Librarians currently report a desire to provide services that not only include but meaningfully support autistic children in their families; however, little research has examined how key stakeholders within the autism community perceive autism-inclusive programming within libraries. This research seeks to explore these perspectives and identify (1) perceived barriers to attending children’s library programs, (2) accommodations and …
