From Diversity To Novelty: Unsupervised Learning For Novel Transposon Identification And Evolutionary Mapping For Large-Scale Genomic Datasets, Rabeya Nazara

All Theses

Transposons play a pivotal role in genome evolution and contribute to genome expansion, with novel transposon discovery offering valuable insights into genetic function and its implications for health and diseases. This study focused on identifying novel transposons within a large-scale genomic dataset using unsupervised machine learning approaches to uncover hidden patterns and detect elements that deviated from known transposon groups. To address the challenge of data scale and to deal with the computational complexity, two complementary approaches were adopted: first, analyzing the entire dataset to picture the broad spectrum of diversity; second, a strategic reduction and filtering method to produce …

Louisiana's Ten Commandments Statute: With Litigation Updates From Arkansas And Texas, Carl H. Esbeck

Faculty Publications

Legislators in conservative states are drawn to a belief that the Ten Commandments [“10/Cs”] underscore American’s moral, jurisprudential, and historical heritage. First the State of Louisiana, and thereafter Arkansas and Texas, enacted legislation requiring the posting of the 10/Cs in every public school and university classroom in the state. This quickly brought on legal challenges by students and their parents, along with a smattering of local clerics, together contending that these laws were unconstitutional, most prominently violations of the Establishment Clause. State attorney generals leaped to defend these statutes making the facial assertion that the 10/Cs are not so much …

The Use Of Ai In Canadian Courts, Shaughnessy Dow

Dalhousie Journal of Legal Studies

Like many other fields, there has been growing discussion about the potential benefits of AI for the law. In light of the Federal Court’s interim principles and guidelines on the use of AI, this paper considers whether AI applications can assist the judiciary with its decision-making function. In doing so, it starts by considering the role that judges play in our legal system, finding that they are often called upon to consider and weigh information with human, emotional qualities and to assess the broader policy implications of their legal rulings. This paper concludes that the optimism of proponents of AI …

A Framework For Interpreting Emojis In Legal Contexts, Anne Merritt

Dalhousie Journal of Legal Studies

In the 2023 case of South West Terminal Ltd. v. Achter Land & Cattle Ltd., a Saskatchewan court found that a thumbs-up emoji, as a standalone item of communication, constituted the acceptance of a contract between a buyer and seller. The trial judge noted that such communication was “the new reality in Canadian society” for which courts should be prepared to interpret novel units of language arising in the digital age. However, an analysis of recent Canadian cases involving emojis shows that courts have not been prepared, with inconsistencies in how emojis are represented in evidence, how they are …

The Reverse Onus At Bail For Intimate Partner Violence: An Unconstitutional And Ineffective Measure, Ella Peterson

Dalhousie Journal of Legal Studies

The recently adopted reverse onus at bail for repeat intimate partner violence is a piece of performative legislation that is ineffectual and may harm those it seeks to protect. Part I of this paper provides an overview of intimate partner violence in Canada in order to contextualize s. 515(6)(b.1) of the Criminal Code. Part II is a Charter assessment of the reverse onus provision at issue, focusing on sections 7 and 11(e). Part III concludes with a critique of the effectiveness of the reverse onus, which fails to address the root causes of intimate partner violence.

Teacher Motivation To Implement Evidence-Based Interventions With Fidelity: Development And Testing Of A New Psychometric Instrument, Jaden Miles Nyberg

Dissertations

The purpose of the present research study is to develop and test a novel psychometric instrument designed to measure teacher motivation to implement evidence-based interventions with fidelity, termed the TMI E-BI. The study addresses four research questions. First, does the TMI E-BI have acceptable inter-item consistency and construct validity? Second, with respect to the TMI E-BI, does the best factor model for explaining teachers’ motivation to implement EBIs with fidelity consist of expectancy, task value, cost, and orientation towards fidelity as related but meaningfully distinct constructs? Third, does the TMI E-BI predict teachers’ self-reported treatment fidelity? Lastly, how do teachers’ …

Supporting Cultural Capital In Undergraduate Biology: Instructor Roles And Practices, Lydia Nicole Mayo

Dissertations

Undergraduate biology students must navigate complex academic environments that require more than content mastery alone. Increasing evidence shows that students’ attitudes, beliefs, and values—such as motivation, confidence, and a sense of belonging—are critical to student engagement, persistence, and success, especially among first-generation college students and those from historically marginalized backgrounds. Therefore, the purpose of this dissertation is to use cultural capital theory to explore how instructor practices in college biology classrooms support these non-content resources, framed as three forms of cultural capital: aspirational, navigational, and emotional capital for college biology.

To investigate this phenomenon, the dissertation integrates three complementary studies. …

Undergraduate Faculty Experiences With Test Remediation, Shauna L. Haynes

Dissertations

Nursing students’ success in didactic courses generally depends on test scores. Students who fail to achieve a designated score might fail the test and/or the course. Test remediation is an intervention that could be implemented in response to a student’s failure. The intent of test remediation is to improve the student’s success on future exams and maximize the likelihood of progression. While remediation for success on the National Council Licensure Examination, standardized exams, and for the achievement of clinical skills were well documented, little research was found on test remediation for individual course exams. The purpose of this study was …

Integrating Diversity, Equity, And Inclusion Into An Undergraduate Sport And Exercise Science Program: A Holistic Case Study Utilizing Social Justice Education, Genevieve R. Altomare

Dissertations

It has been recommended by many scholars to integrate diversity, equity, and inclusion (DEI) content into higher education curricula across disciplines; however, several institutions have yet to do so. The ongoing discourse surrounding social justice continues to influence the careers of future professionals, especially in the fields of sport and exercise science. Yet, there remains a limited understanding of the perceptions and experiences of students who have participated in a college course centered on DEI topics. Therefore, the purpose of this holistic case study was to provide an in-depth examination of a newly developed DEI course by exploring the authentic …

Breaking Ranks: Recognizing Hiring Bias Associated With Different Military Branches, La Kesha Redel Leonard

All Dissertations

This study aimed to address the gap in research on hiring biases against military veterans, with a focus on branch-specific discrimination. While prior research has examined general veteran employment challenges, no existing scholarly studies have explored how stereotypes tied to a veteran’s branch of service influence hiring outcomes. Current approaches, such as diversity and inclusion policies and skills translation programs, overlook subtle yet impactful branch-related implicit and explicit biases against candidates from different branches of the U.S military during the hiring process, leaving a critical gap in workforce reintegration strategies. The purpose of this study was aimed to examine how …

Even In Death, Divided By Law: The Permanent Injustice Of Cemetery Segregation In Southern Illinois And The Legacy Of Isaac Burns, Local Civil War Veteran, Taylor Phillips

Southern Illinois University Law Journal

In death, are we truly equal? A Cemetery in Pinckneyville, Illinois, bears silent witness to a relentless history that preserves a racial divide thought to be buried away. Hidden in the segregated section lies Isaac Burns, an African American Civil War veteran, separated from those buried with honor. His grave lies alongside those of other African Americans buried in an area marked not by the unity of service but by the nation's refusal to see them as equals. Burn's grave is a reminder that the legacy of his sacrifice, once given in the name of unity and freedom, is overshadowed …

Cell Death Helps To Stabilize Populations Of Prochlorococcus, P. Wang, E. A. Laws, C. Liang, X. Liu, J. Chen, Y. Zhong, C. Li, B. Huang

Faculty Publications

Prochlorococcus is one of the dominant phytoplankton species in tropical and subtropical pelagic marine ecosystems. To maintain its population equilibrium in oligotrophic waters, the dominant species Prochlorococcus requires high loss rates to offset its high abundance and growth rates. While theoretical frameworks recognize multiple loss processes for Prochlorococcus (viral lysis, environmental stress, programmed cell death), prevailing population studies attribute main mortality to grazing. This oversight stems from in situ data gaps of non-grazing mortality processes. In this study, we firstly formulated simple differential equations that took account of population losses due to both grazing and cell death. We then used …

Inhibitory Control In Asian Elephants, Gillian Schmitt

Theses and Dissertations

Inhibitory control is defined as the ability to suppress a prepotent motor response in favor of a more efficient or advantageous behavior, and is an important core executive function. Although elephants are known to behave flexibly and display other executive functions, there is currently little information available on if, and to what extent, they display inhibitory control. We tested 16 captive Asian elephants (Elephas maximus) (N = 8 males, 8 females) ranging in age from 4-years-old to 60-years-old at the National Elephant Institute in Thailand using a classic detour paradigm adapted to be more ecologically salient for them through the …

Intergenerational Transmission Of Health: Evidence From Indonesia, Fatima Khan

Theses and Dissertations

This study estimates the causal transmission of health from mothers to their children. Intergenerational associations in health and other human capital outcomes are well established, but those associations may not be causal due to common unobserved factors between a mother and her child. This study employs two-stage least squares, using weather variation as an instrument, to causally identify the relationship between maternal health and child health outcomes in five dimensions: height-for-age, self-reported health, blood pressure, lung capacity, and hemoglobin levels. The data are from the Indonesian Family Life Survey (1993--2014), a longitudinal survey that provides a 21-year look into the …

Modeling Reactive Rarefied Flows In Chemical Vapor Infiltration Using Direct Simulation Monte Carlo, Ege C. Ek

Masters Theses and Doctoral Dissertations

Chemical Vapor Infiltration (CVI) is a key method for fabricating silicon carbide (SiC) matrix composites. Gas-phase precursors flow into a porous fiber, react, and deposit to form the ceramic matrix. Deposition quality and rate are strongly influenced by surface reactions, depending on temperature, gas flow, and reactor pressure. This study applies a computational model to better understand rarefied gas behavior and surface chemistry during CVI. We use the Direct Simulation Monte Carlo method to simulate gas flow and chemical reactions around the fibers. Simulations span Knudsen numbers 0.001–20 and temperatures 1000–1600 K (near‑continuum to free‑molecular). As rarefaction increases, deposition rate …

A Quiet Privilege: Garrity, Internal Investigations, And The Need For A Preference Of Silence Among Public Employees, Jacob Abel

University of Florida Journal of Law & Public Policy

When a public employee is asked to testify against themselves or face termination, they are presented with a trilemma. They may choose to respond to questions falsely, answer truthfully, and suffer criminal sanctions, or remain silent and lose their job. In Garrity v. New Jersey, the Supreme Court resolved this trilemma by ruling that, when a public employee is compelled to answer questions, the Fifth Amendment grants the employee immunity for their testimony. The Supreme Court “solved” the trilemma again, in Gardner v. Broderick, by saying that an employee who is fired for invoking their Fifth Amendment right …

Analyzing The Impact Of Interactive Home Monitoring On Congestive Heart Failure Readmissions: A Program Evaluation, Josh C. Riggs

Doctor of Nursing Practice (DNP) Manuscripts

Hospital readmissions are described as a situation in which a patient is admitted to a hospital within 30-days of being discharged from an earlier inpatient stay and is a critical indicator of care, contributing heavily to the rising healthcare costs in the United States. Heart failure is one of the leading contributors to 30-day hospital readmissions, prompting healthcare organizations to develop and implement policies aimed at reducing these occurrences. This program evaluation examined the effectiveness of the University of Virginia’s (UVA) Interactive Home Monitoring (IHM) program at reducing 30-day hospital readmission rates among patients diagnosed with heart failure (HF). Utilizing …

Do Themes Improve Visitor Outcomes In Interpretive Programs?, Amber K. Hawes

All Theses

Thematic interpretation is widely promoted as being integral to an effective interpretive program. Some studies have suggested that thematic interpretation may enhance visitor outcomes; however, park visitor demographics have changed over the last decade, and others have suggested alternative approaches. In this study, we systematically observed live interpretive programs at 330 programs at 52 National Parks across the United States, monitored the extent and characteristics of theme usage, and collected visitor surveys immediately following each program. We used these data to determine the influence of the presence and characteristics of themes and theme questions on visitor outcomes. The results suggest …

Estimating Price Responsiveness For Service Of A Luxury Transportation Company: A Zero Inflated Poisson Approach, Sydney Butenhoff

All Theses

Estimating price sensitivity is crucial for premium service providers who face inconsistent client engagement. In this study, I investigate both observed ride demand and periods of client inactivity among ABC Transfer’s customers, meaning individuals who may not book rides in a given period but are not necessarily disengaged. ABC Transfer is a luxury ground transportation firm headquartered in upstate South Carolina. Using an unbalanced panel dataset spanning 2012 to 2024, I estimate a Zero-Inflated Poisson (ZIP) model to distinguish between individuals who might still be clients from those who are not likely to be clients any longer. The model accounts …

Two Essays On Index-Based Risk Management In U.S. Rangeland And Livestock Production, Wajdi Belgacem

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation investigates two distinct but complementary dimensions of risk management in United States rangeland agriculture. Essay 1 measures spatial variation in basis risk within the Pasture, Rangeland, and Forage (PRF) rainfall-index program for 176 Nebraska grid cells (1988–2023). By linking official NOAA rainfall indices with 30-m Rangeland Analysis Platform biomass estimates, we find rainfall–forage correlations that peak at 0.45 but display pronounced heterogeneity. The probability that neither insured interval triggers during an actual forage loss averages 12%, rising to nearly 30% in several Sandhills cells, whereas optimally pairing late-spring and summer intervals reduces complete misses below 10%. These results …

Redressing The Harm Of Accelerated Approval, Laura Karas

Articles

The accelerated approval pathway of the United States Food and Drug Administration (FDA) enables drugs to come to market more quickly than would be possible under a traditional FDA approval pathway. Accelerated approval is based upon the agency's determination that changes in a surrogate or intermediate clinical endpoint are "reasonably likely" to predict a clinical benefit meaningful for patients. In essence, the pathway affords sick patients earlier access to potentially beneficial drugs while trials to confirm clinical benefit continue. Accelerated approval has been likened to a social compromise in which promising drugs enter the market sooner in exchange for a …

Hardware And Software Design For A Portable Surgical Training Simulator, Victoria Nelson

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

More than 51 million surgeries are performed on patients annually in the United States. That number grows to 310 million surgeries performed globally each year. Most surgeons go through a minimum of five years of residency – where they train and hone their surgical skills. It is important during this time, and throughout their careers, that they get plenty of practice. Surgical training is time intensive, expensive, and frequently under-resourced. There are finite amounts of surgical training modules for students to share at their facilities. The problem of getting adequate surgical training time continues to exist after surgeons begin their …

Ai Governance In China: A Tale Of Three Digital Empires, Charles C. Wang, Siyi Lin, Xia Wu, Yiman Li

UC Law SF International Law Review

Since 2021, China has strategically expedited artificial intelligence (AI) legislation and refined algorithmic governance to compete with the US and the EU. The rapid growth of algorithm filing cases is a direct result of the “Made in China 2025” Initiative which prioritizes AI development driven by domestic leading tech companies like DeepSeek. As world-class digital powers, China, the US, and the EU diverge in their categorization of AI risks and adoption of regulatory measures. China’s centralized single-agency regulatory infrastructure differs from the multi-agency and decentralized governance models in the US and the EU, respectively. China does not impose the same …

Project Choices: An Experimental Serious Video Game For Performance-Based Risk Assessment, Rachel Bomysoad

Theses, Dissertations and Culminating Projects

Risk assessment for future criminal conduct currently relies on evaluator ratings or self-report measures, with imperfect predictive utility. A new serious (clinical) video game, Project Choices, was developed for assessment and treatment purposes with persons involved with the criminal legal system. Project Choices offers performance-based measurement of individuals’ responses to realistic scenarios relevant to overall criminogenic risk and individual risk factors. The current study aimed to pilot test the newest version of Project Choices (Version 2) using a sample of university students (N = 100), examining gameplay performance metrics (number of risky decisions overall and within individual risk domains) for …

Electrophysiological Markers Of Emotion Dysregulation In Autistic Youth, Rachel G. Mcdonald

Theses, Dissertations and Culminating Projects

Emotion dysregulation (ED) is a transdiagnostic mechanism that is conceptualized as difficultly regulating emotions and deploying appropriate regulation strategies in response to environmental stimuli. Meta-analyses suggest that autistic people, across the lifespan, experience more severe ED as compared to both neurotypical people and those with mental health conditions. Despite elevated risk and evidence linking ED to disruptions in neural mechanisms, no studies to date have examined neural markers of ED in autistic populations. The current project uses multi-method and multi-informant measurement to examine similarities and differences in neural mechanisms of ED in autistic and non-autistic populations. Forty-four youth aged 11—17 …
