The Efficacy Of Open Educational Resources On Achievement Outcomes In Higher Education Institutions, Charles Trevor Alder

Theses and Dissertations

Achievement gaps remain a concern in higher education, reflected in differences in academic performance, retention, and persistence. These gaps often affect students from lower socioeconomic backgrounds and underserved populations. Open educational resources (OER) have been suggested to reduce financial barriers and support student success. This study examined whether student-level and institutional-level factors predict academic performance in a business management course using OER. Average quiz scores were collected from students across 12 higher education institutions and analyzed using hierarchical linear modeling. Colleges were included in the analysis to determine whether outcomes differed based on the proportion of minority and Pell-eligible students. …

Teacher Retention: Do Job Satisfaction, Support From Administrators, Professional Development Opportunities, Student Behavior, And School Culture Directly Affect Whether A Teacher Decides To Stay At A School Or Leave?, Robert Dawson Parrott

Education Theses and Dissertations

Teacher retention has reached crisis levels nationwide, with nearly 50% of beginning teachers leaving within five years. Teacher attrition increased to 27.3% in 2022–2023 in a large suburban school district in North Texas. This translated to over $1.1 million dollars in teacher salary expenditures alone. This Dissertation in Practice utilized mixed-methods research grounded in Improvement Science and Plan-Do-Study-Act cycles to explore five campus-level contributors to teacher retention that fell under the control of building-level administrators: job satisfaction, administrative support, professional development, campus culture, and student behavior supports. In Phase 1 a teacher intent survey (n = 63) and focus group …

Using United States Medicare Program Claims To Identify Reliable Measures Of Low Value Services Influenced By Primary Care Physician Decisions, Chris Fleming, Dmitriy Poznyak, Rhea E. Powell, Claire Erba, Eunhae Shin, Rui Wang, Claire Burkhart, Arkadipta Ghosh, Eugene C. Rich

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: Low-value services (LVS) are those that “… provide little to no benefit to patients….”¹ Among an existing set of 31 LVS are invasive procedures not typically performed by primary care physicians (PCPs), and other LVS that may be commonly provided by specialists. To facilitate research on the role of primary care physicians in low-value care, we sought to identify the reliability of two subsets of LVS measures that are more directly subject to PCPs’ decisions. We refer to these as primary care adjacent (“PCA”) LVS measures.

METHODS: Retrospective observational cohort study to identify which of a 31-item LVS …

Fast Radio Bursts From The Nonlinear Evolution Of Low Frequency Plasma Waves In The Magnetosphere Of Magnetars, Dominic Bernardi

Arts & Sciences Graduate Student Theses and Dissertations

Fast radio bursts (FRBs) are millisecond-duration radio bursts with applications as cosmic probes. However, their physical origins remain largely unknown. Magnetars are natural candidates for producing FRBs due to their compact size, extremely strong magnetic fields, and intrinsically dynamic nature. In this thesis, I develop a model for FRB production grounded in both a concrete triggering mechanism and a viable emission process. This process begins by launching low-frequency plasma waves into the magnetosphere. I show that energetic fast magnetosonic waves can naturally be produced in the magnetosphere, independent of how these waves are launched. Regardless of whether these waves are …

From Athens To Jerusalem: Platonism, Richard Owen, And The Road Not Taken In Biology, Michael A. Flannery

Libraries Professional Work

Tertullian provocatively asked (circa 200 AD), “What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church?” The relationship between formal philosophy and religion has been a contentious battleground ever since. It has historically come into sharpest focus in biology generally, and evolutionary theory specifically. Charles Darwin clearly won the day in the short-term. His evolutionary functionalism looked like an inglorious abandonment of time-honored metaphysical realism for positivist empirical reductionism with a concomitant horizontalization of perspective that has secularized and flattened the intellectual landscape. But more recently the rise of evo-devo (evolutionary developmental …

Urban Teachers’ Perceptions Of The Influence Of Their Alternate Route Certification Programs On Their Retention, Jenifer Phillips

Student Theses and Dissertations

This qualitative case study explored how secondary teachers in one urban public school system described their experiences in alternate-route certification programs and how those experiences shaped their decisions to stay in the classroom. As districts continue relying on alternate-route teachers to address ongoing shortages, it is important to understand how teachers interpret their preparation, coaching, and early classroom experiences through the lens of adult learning, or andragogy, and what supports they believe actually helped them succeed with students, particularly in areas such as phonological awareness, classroom management, and foundational instructional practices. A total of 196 teachers met the study’s criteria …

Assessing The Effectiveness Of Wetland Reserve Easements As Habitat For Birds In The Mississippi Alluvial Valley Of Eastern Arkansas, Colin K. Dobson

Student Theses and Dissertations

Globally, wetland habitats suffered major declines during the 20th century. In the 1990s, the United States government created the Wetland Reserve Program (later consolidated into the Agricultural Conservation Easement Program), to combat the loss of wetlands. Despite success in attracting landowners, minimal monitoring of properties enrolled into the program (easements) has occurred. In this study, we monitored avian communities at easements, compared avian diversity at easements to agriculture and bottomland forests, and quantified microhabitat, site-specific, and surrounding landscape features at easements. We also studied the demographic rates of an indicator species of bottomland forests, the Prothonotary Warbler (Protonotaria citrea) at …

Safety Of Concurrent Benzodiazepine Use During Buprenorphine Treatment For Opioid Use Disorder: A Systematic Review Of Real-World Evidence And Risk-Of-Bias Assessment, Abolfazl Sadeghi, Tyler J. Varisco, Parastoo Mousavi

Posters

Background: Concurrent benzodiazepine (BZD) use among patients receiving buprenorphine for opioid use disorder (OUD) is common in routine care and presents a critical clinical dilemma. While buprenorphine improves survival and reduces overdose risk, co-exposure to central nervous system depressants may increase the risk of adverse events. However, medication-specific real-world evidence remains limited, and existing studies report conflicting findings. Objective: To synthesize real-world observational evidence on safety outcomes associated with concurrent BZD use during buprenorphine treatment and to critically appraise study quality using ROBINS-I V2. Methods: We conducted a critical narrative review following PRISMA guidelines. PubMed/MEDLINE, Embase, and Web of Science …

An Empirical Study Of Rlvr Fine-Tuning For Mathematical Problem Solving In Llms, Rashmi Konnur

Master’s Dissertations

Large language models have shown immense improvement in coding and math performances thanks to reinforcement learning boosted algorithms. However, its true impact on broadening the reasoning and analytical capacities of an LLM is still contended. In this dissertation, we outline the foundations of Large Language Models, and delve into Reinforcement Learning with Verifiable Rewards (RLVR). We discuss various strategies to efficiently manipulate memory during a fine tuning update. We finally perform RLVR fine-tuning techniques on different models with varied use cases and compare their performances, which corroborate the efficiency of RLVR.

Freedom Of Thought And Speech: Charles C. Burleigh And The Refraction Of Quaker Principles In Abolitionist Non-Violence, Jennifer Rycenga

Faculty Research, Scholarly, and Creative Activity

Charles C. Burleigh (1810-1878), an important American Abolitionist speaker, agent, and theorist, was also an advocate for non-violent resistance. He had many opportunities across his 30+ years fighting slavery to test his non-violent principles, due to mob violence against Abolitionist gatherings. At some of the most significant of these events, such as the destruction of the Abolitionist's Pennsylvania Hall in 1838, Burleigh witnessed the strength and resolve of African-American and white women in upholding non-violence and moral suasion.

While Burleigh never became a member of the Society of Friends, his life and thought run parallel to ideas and practices of …
