Effect Of Personal, Organizational, And Work Attributes On Long-Term Care Nurses’ Intent To Stay, Marilyn J. Hodgins, Caitlin Mcarthur, Janice M. Keefe, Rick Audas, Carole Estabrooks, Rose Mccloskey, Gail Tomblin Murphy

International Nursing Research Congress (INRC)

A stable workforce is key to creating and maintaining a positive work environment, enhancing productivity, reducing adverse events, and lowering recruitment and orientation costs (De Vries et al., 2023). Stability in staffing of long-term care (LTC) facilities is particularly important given the vulnerability of the residents and increasing complexity of their physical and psychosocial care needs (Calver et al., 2025; Virdo & Daly, 2025). However, before action can be taken to address high turnover rates among LTC staff (Gandhi et al., 2021), factors influencing such decisions need to be understood.

PURPOSE: To examine extent that LTC nurses’ intent to stay …

Analyzing Proposed Federal Policy For Nurse-To-Patient Staffing Ratios: Insights From State Data, Brayton Amidon

International Nursing Research Congress (INRC)

Background: Approaches to nurse staffing in the United States is a highly debated topic. Nurses, policymakers, and hospital administrators are interested in improving patient outcomes and many researchers have looked to safe staffing as a way to improve these outcomes (Costa & Yakusheva, 2016). Mandated nurse-to-patient staffing ratios have been implemented at the state level and have been proposed at the federal level (Bartmess et al., 2021). Many state hospital associations oppose mandated staffing ratios as they claim these ratios could exacerbate the nursing shortage, deny nurses the flexibility to determine staffing needs, limit access to healthcare, and increase hospital …

Decisions Under Fire: Healthcare Students Reactions To An Active Shooter Simulation, Linda S. James, Sarah Hirsch

International Nursing Research Congress (INRC)

The Joint Commission (2021) recommended that hospitals train their employees on how to act and respond during an AS event. Students are required to complete agency trainings (i.e. fire, HAZMAT etc.) prior to attending practicum but are not required to complete AS response, sending them into clinical settings ill prepared.

The purpose of this study was to examine healthcare professional students’ moral and ethical challenges experienced from an interprofessional active shooter (AS) simulation. This simulation also explored ethical decision-making and provided students an opportunity to practice critical thinking in high-stress situation and had a secondary impact on their development of …

The Dual Impact Of Professional And Community Interventions On Recidivism, Anjelika M. Dillard

Master of Arts in Human Services

This capstone project evaluates the effectiveness of professional and community interventions in reducing criminal recidivism and facilitating successful community reintegration for justice-involved individuals. Grounded in the Risk-Need-Responsivity (RNR) model, Desistance Theory, and Trauma-Informed Care frameworks, this study synthesizes contemporary behavioral health and criminological literature to examine how institutional programming and post-release community support interact to foster long-term behavioral change. The findings demonstrate that while evidence-based institutional treatments—such as Cognitive-Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and targeted vocational training—provide essential foundations for cognitive restructuring and skill acquisition, institutional programming alone is insufficient to prevent re-offending. Long-term desistance depends on an …

Feedback Indices To Evaluate Llm Responses To Rebuttals For Multiple Choice Type Questions, Justin C. Dunlap, Anne-Simone Parent, Ralf Widenhorn

Physics Faculty Publications and Presentations

We present a set of indices designed to characterize Large Language Model (LLM) responses when challenged with rebuttals during a chat. Assessing how LLMs respond to user dissent is crucial for understanding their reliability and behavior patterns, yet the complexity of human-LLM interactions makes systematic evaluation challenging. Our approach employs a fictitious-response rebuttal method that quantifies LLM behavior when presented with multiple-choice questions followed by deliberate challenges to their fictitious previous response. The indices are specifically designed to detect and measure what could be characterized as sycophantic behavior (excessive agreement with user challenges) or stubborn responses (rigid adherence to the …

Arcsecond-Level Pointing Accuracy In A Cubesat: Development And Verification Of The High-Precision Pointing System For The Cubespec Mission, Leonardo Peri

Small Satellite Conference

Mission and objectives 

CubeSpec is a 12U CubeSat mission designed to demonstrate high-resolution stellar spectroscopy from a small, low-cost space platform. 

Its scientific objectives require the payload line-of-sight to remain stable within a few arcseconds. This is beyond the capability of conventional CubeSat Attitude Determination & Control Systems (ADCS). 

To meet this challenge, CubeSpec uses a dual-stage pointing architecture: the spacecraft ADCS provides coarse body pointing, while a High-Precision Pointing Platform applies fast, precise corrections directly to the payload line-of-sight.

Multi-Phase Guidance And Control For Small Satellite Docking Via Deep Reinforcement Learning, Tanner Gill, Greg Furlich, Nisar Ahmed

Small Satellite Conference

As interest in small satellite Rendezvous, Proximity Operations, and Docking (RPOD) grows, so does the need for high-level autonomy in space systems. Current systems relying on constrained hardware and ground-in-the-loop decision-making are ill-equipped for the evolving, contested space domain. Recent research on autonomous spacecraft guidance and control has moved beyond established optimal control and trajectory optimization methods to incorporate Reinforcement Learning (RL), though these efforts have predominantly focused on a single operational phase. This research advances small satellite docking autonomy by formulating the reference scenario as a Hierarchical Markov Decision Process (H-MDP), expanding the scope of the learned guidance and …

The Ecological Impacts Of Un-Protecting Forests: The Case Of Gold Mining In Ghana, Tate Alexander Barend

Master's Theses

This paper estimates the causal effect of Ghana’s Legislative Instrument 2462 (L.I. 2462) on deforestation in protected areas. The policy redefined the regulatory regime governing small-scale gold mining in protected areas, moving from prohibition to discretionary permitting. I exploit the implementation of L.I. 2462 as a policy shock and apply a difference-in-differences event-study framework to a propensity score–matched sample of pixels derived from high-resolution satellite images. Contrary to widespread concerns that the policy would accelerate deforestation, the results provide no evidence of large-scale vegetation loss in exposed protected areas following the policy change. Instead, protected area pixels located within 5 …
