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 …

Exploring Perspectives Of Autistic Individuals And Caregivers On Autism Inclusive Services In Public Libraries, Ayva J. Rose Apr 2026

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 …

Evaluating The Geographic Patterns In Isotopic Composition For Nesting Hawksbill Sea Turtles In The Wider Caribbean By Coupling Satellite Telemetry And Stable Isotopes, Anna Kreiger

Electronic Theses and Dissertations

Combining satellite telemetry and stable isotope analysis offers a framework for inferring sea turtle foraging habitats when spatial isotopic gradients exist. We evaluated this combined approach using carbon (δ13C) and nitrogen (δ1⁵N) isotope values from critically endangered hawksbill turtles (Eretmochelys imbricata) nesting at Buck Island Reef National Monument, U.S. Virgin Islands (N=31), and Long Island (Jumby Bay), Antigua (N = 31). Nesting females were satellite-tracked to identify foraging areas and sampled for skin tissue, and Empirical Bayesian Kriging was used to generate basin-scale δ13C and δ1⁵N isoscapes. Tracked turtles foraged widely across the Caribbean Basin, including the Greater …

Residents Vs. Tourists: Understanding The Role Of Coastal Tourism Experience In Conservation Behaviours, Qian Chen, Rong Huang, Jinhua Zhang, Thatsanawalai Imong

Plymouth Business School

This study examines the factors influencing coastal conservation behaviours by integrating the Theory of Planned Behaviour (TPB) with coastal tourism experiences. Conducted in Plymouth, UK, the research assesses how attitudes, subjective norms, perceived behavioural control (PBC), and tourism experiences shape conservation intentions and engagement among residents and tourists. The findings reveal that PBC is the most influential factor associated with conservation intentions in the overall model, while coastal tourism experiences significantly influence engagement, particularly among tourists. Residents' conservation intentions are more influenced by attitudes, whereas tourists are driven by their tourism experiences. These findings highlight the need for tailored conservation …

Acute Traumatic Aortic Injury: What The Radiologist Needs To Know, Kristina Ramirez-Garcia, Catalina Jaramillo, Emma Ferguson, Jason Au, Erika Odisio, Gustavo S Oderich, Daniel Ocazionez, Cihan Duran, Thanila Macedo

Faculty, Staff and Students Publications

Acute traumatic aortic injury (ATAI) is a rare but life-threatening consequence of blunt trauma that requires prompt diagnosis and accurate imaging assessment. This review presents an imaging-based approach to ATAI, with emphasis on computed tomography angiography (CTA) as the first-line modality for diagnosis, grading, treatment planning, and follow-up. CTA enables the detection of both direct and indirect signs while also allowing for the assessment of lesion severity, extent, and associated findings that may influence management. Familiarity with common mimics and anatomic variants improves diagnostic confidence and helps avoid false positive interpretations. Careful protocol optimization, including multiphasic acquisition, bolus timing, and …

Understanding Parents' Perspectives On Responsible Ai For Children's Self-Directed Learning, Jingyi Xie, Chuhao Wu, Ge Wang, Rui Yu, He Zhang, Ronald Metoyer, Si Chen

Faculty Research, Scholarly, and Creative Activity

Generative AI is increasingly present in children's learning environments, yet little is known about how families navigate this technology in middle childhood (ages 7-13), when parental guidance remains strong but children seek independence. Drawing on self-directed learning (SDL), we explore how parents in our exploratory sample perceived children's emerging self-directness and agency. Through focus groups with 13 parent-child pairs, we examine parents' views on children's AI literacy development, readiness factors, and mediation strategies. Parents described emergent pathways shaped by screen time, self-directness, and knowledge growth. They often confined AI to learning-only contexts, positioning it as a tutor while overlooking non-learning …

Investigating The Relationship Between Psoriatic Arthritis And Peyronie’S Disease: A Case Study Analysis, Michael J. Evans, Vincent J. Schmidt, Benjamin Kossman, Dylan Hafer, Curtis King

Student Publications

The relationship between psoriatic arthritis (PsA) and Peyronie’s disease (PD) remains poorly understood. PsA is a chronic immune-mediated inflammatory disease, whereas PD is a fibroproliferative disorder of the penile tunica albuginea that leads to penile curvature, pain, and sexual dysfunction. Both conditions involve chronic inflammation and dysregulated tissue remodeling. We report the case of a 42-year-old man with long-standing PsA who developed acute inflammatory PD shortly after discontinuing biologic therapy because of loss of insurance and medication nonadherence. The patient presented with new-onset penile pain and a palpable dorsal plaque in the setting of uncontrolled psoriatic disease. Penile ultrasound demonstrated …

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 …

Joint Representation Of Spouses And Romantic Partners: Ethical Considerations For Estate Planners, Elizabeth R. Carter Apr 2026

Joint Representation Of Spouses And Romantic Partners: Ethical Considerations For Estate Planners, Elizabeth R. Carter

Arkansas Law Review

Attorneys routinely represent married couples jointly in estate planning matters. Joint representation of married couples—and, increasingly, unmarried romantic partners—is a routine practice for most estate planners. This practice was not always so widely accepted. Beginning in the 1990s, scholars, attorneys, and interest groups successfully advocated for the widespread acceptance of joint representation in estate planning. In a joint representation, the attorney represents both individuals in a collaborative form of representation where confidences and goals are shared between both clients and the attorney. Proponents of joint representation in the estate planning setting argue that it reduces costs, is more consistent with …

Mathematical Modelling And Optimisation Of The Reactor For The Esterification Process Of Safflower Oil With N-Butyl Alcohol, Sadritdin Makhamatdinovich Turabdjanov Academician, Hasan Sadriddin Ugli Fozilov, Ozoda Bakhronovna Axmedova, Sadriddin Fayzullayevich Fozilov

Technical science and innovation

This study addresses the mathematical modelling and optimisation of a reactor for the esterification of safflower oil with n-butyl alcohol. To improve process controllability and reduce the need for numerous pilot-scale trials, an ideal-mixing continuous stirred-tank reactor (CSTR) model was adopted. Incorporating reaction kinetics, the effect of contact time on the relative viscosity of the product mixture was analysed. The modelling results indicate that achieving an acceptable degree of feedstock conversion is difficult when a single ideal-mixing reactor is used. Therefore, a CSTR cascade was proposed, and the configuration with N = 2 reactors was selected as the most appropriate …

Continuous Light And Pinealectomy: Two Models Of Melatonin Deficiency Revealing Distinct Interactions With Vitamin D Deficiency On Blood Parameters, Rebaz Sedeeq Shekh, Ismail Mustafa Maulood

Polytechnic Journal

Modern lifestyles reduce sunlight exposure and increase artificial light at night, potentially promoting vitamin D deficiency (VDD) and melatonin (MEL) suppression. The two hormones regulate immunity, erythropoiesis, and platelet (PLT) indices, but their combined hematological effects are not well characterized. We investigated the independent and combined effects of VDD and MEL deficiency on leukocyte profiles, erythrocyte indices, and PLT parameters in albino rats using two 12-week models (n = 8/group): continuous light (CL)-induced MEL suppression (Control, CL, VDD, and CL + VDD) and pinealectomy (Px)-induced MEL deficiency (Sham. Px, VDD, Px + VDD). Complete blood counts (CBCs) and inflammation-related ratios …
