Llamoco: Instruction Tuning Of Large Language Models For Optimization Code Generation, Zeyuan Ma, Yue-Jiao Gong, Hongshu Guo, Jiacheng Chen, Yining Ma, Zhiguang Cao

Research Collection School Of Computing and Information Systems

Recently, combining the strength of large language models (LLMs) and Evolutionary Computation (EC) has shown promising results for addressing optimization problems. It typically involves either iterative next-step solution seeking or directly prompting LLMs to generate critical optimization codes. However, these methods often suffer from low computational efficiency, high sensitivity to prompt design, and a lack of domain-specific knowledge. We introduce LLaMoCo, the first instruction-tuning framework designed to adapt LLMs for solving optimization problems in a code-to-code manner. LLaMoCo features a comprehensive instruction set that includes code-style problem descriptions as input prompts and robust optimization codes from expert EC optimizers as …

Understanding Wage Theft: Beyond The Numbers Through Community Practice, Lived Experience, And Research, André Simões Da Silva, Lenita Reason, Cristina Araujo Brinkerhoff

Gastón Institute Publications

Wage theft is a widespread form of labor exploitation that disproportionately affects immigrant and other vulnerable workers. This report examines the scope and impact of wage theft in Massachusetts by analyzing case data from the Brazilian Worker Center (BWC) alongside wage and labor enforcement data from the Massachusetts Attorney General’s Office (AGO). The analysis demonstrates how wage theft affects immigrant workers across industries, with particularly high numbers of cases in construction, cleaning, and hospitality. The data also reveal significant gaps in the reporting and enforcement of wage violations, particularly among domestic workers, whose cases are likely substantially underrepresented in available …

Effects Of Pressure-Based Virtual Reality Training On Mental Toughness In Athletes, Rylee J. Aspinwall

UNF Graduate Theses and Dissertations

Athletes often underperform in high-pressure situations due to challenges in emotional regulation rather than deficits in physical skill. Mental toughness, broadly defined as the ability to maintain performance under stress, is a key determinant of athletic success but remains difficult to train using traditional methods. Virtual reality (VR) offers a controlled and immersive environment for simulating competitive pressure; however, its application for training mental toughness remains limited. The present study examined the effects of pressure-based VR training on psychological and physiological responses in collegiate baseball and softball athletes. Participants completed up to eight VR training sessions under either high-pressure or …

Regulation And Localization Of Urease In Sporosarcina Pasteurii: Implications For Coastal Protection, Amar Kosovac

UNF Graduate Theses and Dissertations

Coastal erosion is a persistent problem exacerbated by global warming. As the climate changes, the southeastern coast is likely to experience an increased frequency and intensity of storms, which can significantly damage the coastline. The coast is crucial as it serves as a habitat for numerous animals, supports tourism, and underpins infrastructure. Microbially induced calcite precipitation (MICP) is a novel method to enhance erosion resistance in sandy soils using the non-pathogenic bacterium Sporosarcina pasteurii. S. pasteurii produces urease to catalyze urea into bicarbonate, which drives the precipitation of calcium carbonate. Maximal expression of urease is a limiting factor for …

Social Support, Trauma And Neurophysiological Stress, Devon S. Glicken

UNF Graduate Theses and Dissertations

Traumatic life experiences and the prolonged effects of stress can negatively impact an individual’s mental and physical health. Hyperreactivity to acute stressors can often be seen in individuals with anxiety, depression, and suicidal ideations, conditions commonly observed with endocrine dysfunction. How do traumatic experiences, particularly experiences related to military affiliation, influence stress responses and feelings of burdensomeness and thwarted belongingness? This study predicted (1) that military-affiliated individuals (and those with PTSD symptomology and high perceived life stress) will have heightened neurophysiological responses to minor levels of acute stress compared to individuals without military-affiliations (and those without PTSD symptomology or high …

UNF Graduate Theses and Dissertations

Leadership programs and readiness in schools, particularly those in Florida, is well studied. However, few studies have investigated how current assistant principals who have completed Clay County District School’s Aspiring Assistant Principal Program describe their experiences, believe the program has prepared them for the realities of school leadership, or identify the most impactful elements that have supported their leadership development. This case study seeks to collect foundational research knowledge by analyzing data from the program, participants, and key facilitators. Using a sampling of current assistant principals who have completed the Aspiring Assistant Principal Program, this research examines the results in …

Development And Testing Of A Low-Cost Inertial Impact Sensor, Gabriel Michael Pesek

UNF Graduate Theses and Dissertations

Acceleration sensors have seen increasing usage within sports to detect when somebody receives an impact to their head which can potentially lead to Traumatic Brain Injury (TBI). While adoption of these sensors has steadily risen, the cost of these sensors is often cited as a reason they have not been as widely adopted, especially for amateur teams. This leads to the need for a lower-cost option for detecting these impacts. To fill this gap, a low-cost, lightweight acceleration sensor was designed that exploits the inertia of a working fluid on impact in order to rupture a metallic membrane which acts …

Regulation Of Private Higher Education In Mexico: How Non-Elite Institutions Navigate Authorization, Edson Eduardo Navarro Meza

Electronic Theses & Dissertations (2024 - present)

Low quality, excessive commercialization, fraud, profit in disguise, and predatory dynamics remain the most pressing regulatory challenges in the context of private higher education in Mexico. These problems have been largely attributed to the ineffectiveness of authorization mechanisms, which have repeatedly become the focus of controversy and criticism from social, academic, and media sectors regarding their role in shaping the development of the sector. Some observers blame the government for its inaction in the face of rapid institutional proliferation, as well as for maintaining authorization procedures that have proven to be ineffective gatekeepers of sectoral expansion. Others place responsibility on …

Three Essays In Labor Economics, Yoritsugu Shimazu

Electronic Theses & Dissertations (2024 - present)

The first chapter decomposes aggregate productivity growth into a pure-technology contribution and an allocative-efficiency contribution for Japan and the United States, applying a single estimation methodology symmetrically to comparable firm-level panels. Production functions are estimated by the Gandhi, Navarro, and Rivers (2020) gross-output procedure under monopolistic competition (GNR-MC), which recovers firm-level price markups and wage markdowns, and these enter the Baqaee–Farhi (2020) decomposition through the closed form of Aoki et al. (2024). Both panels are drawn from Compustat with identical pre-processing and estimation, and we close the markup-level identification gap that GNR leave open with a normalization anchored on the …

Hepatitis C Among Persons Who Inject Drugs In New York State: Progress Towards Elimination, Meredith A. Barranco

Electronic Theses & Dissertations (2024 - present)

Background: Hepatitis C virus (HCV) infection is one of the leading causes of liver disease in the United States (US) and worldwide. In the United States today, HCV is transmitted primarily through injection drug use (IDU) and therefore disproportionately impacts persons who inject drugs (PWID), a population with a range of complex social and health needs. HCV is not vaccine-preventable but can be cured in over 90% of cases with an 8–12-week course of daily direct-acting antiviral (DAA) medication. Since approval of curative medications in 2014, various jurisdictions have developed plans to eliminate HCV. In 2021, the New York State …

Bayesian Modelling On Periodically And Multiple Periodically Correlated Time Series Data, Jie Yao

Electronic Theses & Dissertations (2024 - present)

Time series with multiple periodically correlated (MPC) components present a complex challenge, with relatively limited prior research. Most existing models are designed for simpler periodically correlated (PC) components and often struggle with over-parameterization, optimization issues, and capturing complex PC patterns within a time series. Frequency separation techniques can help preserve the correlation structure of individual PC components, while Bayesian methods can integrate new and prior information to refine beliefs about these components. This study proposes a two-stage approach that combines frequency separation and Bayesian techniques to forecast PC and MPC time series data. This method aims to demonstrate improved effectiveness …

The Effects Of Vitamin K On Neuronal Ferroptosis, Chelsey P. Eighmey

Dementia is a crippling illness affecting millions worldwide causing significant public health burdens with long-term care. The lack of treatment options results in many years of suffering for affected individuals and their loved ones who often become primary caretakers. Decades of study have focused on treating dementia with little-to-no success, so an emphasis is needed on attempting to prevent disease progression altogether. This research explored vitamin K as a potential strategy for prevention of dementia onset or progression through the mechanism of suppressing ferroptosis. Ferroptosis is a type of cell death suggested to contribute to the hallmark traits of Alzheimer’s …

Population Genomics And Evolution Of Pseudomonas Aeruginosa, Samara T. Choudhury

Electronic Theses & Dissertations (2024 - present)

Pseudomonas aeruginosa is a Gram-negative bacterium ubiquitous in diverse environments and an opportunistic pathogen in humans. It is a leading cause of chronic lung infections in cystic fibrosis patients and of hospital-acquired pneumonia and sepsis. With a large flexible genome and abundant mobile genetic elements, P. aeruginosa exhibits high levels of antimicrobial resistance (AMR), making it a significant public health threat. Evolutionary processes such as homologous recombination, and horizontal gene transfer generate extensive genomic diversity in this species and facilitate the spread of resistance genes. In this dissertation, I investigate the genetic and evolutionary factors shaping P. aeruginosa population structure …

The Relationship Between Interoceptive Awareness And Eating Disorder Symptomatology, Madelyn G. Johnson

Electronic Theses & Dissertations (2024 - present)

Interoceptive awareness (IA; e.g., the ability to perceive and interpret internal bodily sensations) is increasingly recognized as central to eating disorder (ED) psychopathology, yet findings remain mixed regarding whether heightened IA is protective or maladaptive. Across two studies using a sample of 654 college students (Mage = 18.74, SD = 1.56; 46% White; 58% female) from a large northeastern U.S. university, we examined (1) how specific IA facets relate to ED symptom severity, and (2) whether anxiety sensitivity (AS) helps explain these associations. In Study 1, linear regressions predicting Eating Disorder Examination Questionnaire–7 (EDE-Q7) scores showed that nearly all MAIA-2 …

Analysis Of The Thermodynamic Variables Associated With Hawaiian Extreme Precipitation Using The Fraction Of Attributable Risk (Far), Matthew J. Sinnenberg

Electronic Theses & Dissertations (2024 - present)

The Hawaiian Islands experience extreme maxima in precipitation that vary spatially, by season, and in response to different teleconnection patterns. Due to the islands’ unique geography, they are not well-resolved by global climate models, necessitating a focused assessment to identify  climatological trends. In this study, a probability-based analysis was conducted on regionally averaged thermodynamic variables relevant to the formation of extreme events. The primary objective was to evaluate whether changes in the occurrence of extreme conditions have occurred and to understand how the El Niño-Southern Oscillation (ENSO) influences these occurrence rates.

Hourly data from ERA5 spanning 1980-2019 were resampled to …

Light And Fire: Kerosene And The Rise And Fall Of Standard Oil, 1859-1911, Minseok Jang

Electronic Theses & Dissertations (2024 - present)

This dissertation revisits the rise and fall of Standard Oil between 1859 and 1911 through the lens of petroleum’s materiality and the fire hazards it posed. Moving beyond traditional narratives that focus on the company’s corporate strategy, this study argues that the volatility of petroleum and the global consumer experience of its environmental risks were central to shaping the company’s trajectory. The research highlights how Standard Oil struggled to control the flammable nature of kerosene—the primary petroleum product used for illumination at the time—before aligning with Great Britain’s advanced inspection technologies and regulatory frameworks. This transimperial cooperation enabled Standard Oil …

Investigating A Mindfulness Curriculum And Prompting For Generalization On Overall Engagement Time, Caitlyn Ruggiero

Electronic Theses & Dissertations (2024 - present)

Mindfulness is a practice that has existed for centuries (Felver et al., 2022) and has been adapted to address various aspects of human life. Among the various uses of mindfulness practices, they have been adapted for use in school settings to support the use of adaptive learning behaviors in the classroom. For the target behavior to change in the natural setting, the student receiving intervention must be able to generalize the learned mindfulness skills to the classroom. The current study aimed to determine whether participation in the Soles of the Feet mindfulness intervention increased students’ overall engagement time (OET) in …

Providers' Perceptions Of Barriers And Facilitators To Implementing Non-Pharmacological Treatment For Adults With Chronic Pain: A Meta-Synthesis, Mikhaela Mcfarlin

Electronic Theses & Dissertations (2024 - present)

Background. Chronic pain is a public health concern impacting approximately 20% of adults in the U.S. Nonpharmacological interventions are considered first-line treatments for patients with chronic pain, yet nonpharmacological interventions remain significantly underutilized. While previous research has explored barriers from the patient’s perspective, limited attention has been paid to providers’ experiences implementing these treatments. This qualitative meta-synthesis aimed to examine provider-perceived barriers and facilitators to implementing nonpharmacolgical treatments for adults with chronic pain. Methods. Independent reviewers conducted systematic searches across PubMed, PsycInfo, CINAHL, and ProQuest Dissertations using relevant (e.g., “mental health provider”, “nonpharmacological”) and applied inclusion criteria to …

Disruptive behaviors in the classroom setting present immediate challenges for both students and teachers and are associated with a host of negative, long-term outcomes. Antecedent interventions are a group of behavior management strategies that can be used to target disruptive behaviors before they occur. This study consisted of a systematic review and meta-analysis of school-based antecedent interventions that were derived from a structural analysis. The results indicated that structural analytic research on school-based antecedent interventions has been conducted with students across diverse educational settings and with students with a variety of disabilities and conditions. Elementary school students and male students …

Improving Clinical Decision-Making: Reducing The Affect Heuristic In Substance Use Treatment, Corey M. Monley

Electronic Theses & Dissertations (2024 - present)

Therapists are at risk for engaging in the affect heuristic, which occurs when automatic emotional reactions influence clinical decision-making more than objective data about clients. Emotional reactions are common when treating clients using substances (CUS), but the influence of the affect heuristic on therapists’ clinical decision-making with CUS has yet to be quantified. This study investigated (1) the extent to which therapist trainees engage in the affect heuristic with CUS and (2) whether it can be reduced through brief cognitive science training. Graduate-level therapists (n = 130) were randomized to one of two conditions: brief online training involving …

Paying The Price: How Financial And Health Stress Can Impact Incidental Memory In The Survival Processing Paradigm, Bailey C. Hall

Electronic Theses & Dissertations (2024 - present)

Cognitive psychologists have examined how evolutionary pressures can shape memory systems and how survival-relevant information is processed. Nairne et al. (2007) established the survival processing paradigm and showed that processing information within a survival context reliably enhances later recall. Previous research has identified academic pressure and financial stress as the most influential stressors for undergraduate students (Patel & Lewis, 2023). Financial stress is widespread and influences multiple domains of life, including health behaviors and psychological well-being (Northern et al., 2010). In this study, two scenarios were created to explore financial and health stress compared to the original grassland survival scenario. …

Punishment, Fast And Slow: Five Experiments On Behavioral Economics In The Mass Incarceration Context, Nathaniel M. Schutten

Electronic Theses & Dissertations (2024 - present)

As many jurisdictions across the United States seek to reduce their prison populations, a pressing question is whether the public will support the reforms necessary to do so. Public openness to reform likely varies across policy areas, with the path of least public resistance occurring where attitudes are the most malleable and loosely held. A major challenge, however, is that traditional methods for measuring public opinion are poorly suited to identifying which policy areas are characterized by such weakly held views.

This dissertation develops a novel behavioral economics framework for identifying these areas. I theorize that when public opinion is …

Family Routines And Cognitive Emotion Regulation: The Role Of Harsh Parenting And Family Activities, Vidhi Jain

Electronic Theses & Dissertations (2024 - present)

Cognitive emotion regulation (CER), consisting of adaptive and maladaptive strategies, is a critical developmental process linked to various well-being outcomes across the lifespan. Family contexts such as daily routines, parenting, and engagement shape the development of emotion regulation. Existing literature generally links family routines to better CER outcomes (Selman & Dilworth-Bart, 2023), but has not yet investigated the impact of routines in adverse family environments. The present study examined whether harsh parenting and the frequency of shared family activities jointly moderate the relationship between family routines and adaptive and maladaptive CER. A sample of emerging adults (N = 210; …

Associations Between Neighborhood Physical And Social Stressors During Sensitive Developmental Periods And Substance Use In Early Adulthood, Abigail M. Ulofoshio

Electronic Theses & Dissertations (2024 - present)

Background

Substance use is a major public health problem. Neighborhood disadvantage and related stressors have been linked to increased substance use in adolescence and early adulthood, although findings are mixed. No studies have explored whether the timing or accumulation of neighborhood stressors in childhood and adolescence impact substance use in early adulthood. This study aims to investigate to what extent physical and social neighborhood stress during sensitive developmental periods influence substance use dependency and illicit substance use in early adulthood.

Methods

We analyzed an imputed sample (n = 7,494) from the Avon Longitudinal Study of Parents and Children (ALSPAC), a …

Mass Homicides And Mass Shootings: Comparisons, Trends, And Unpacking Further, Stefana E. Lotempio

Electronic Theses & Dissertations (2024 - present)

Mass shootings have garnered more public attention in recent years, in large part due to their increase in both frequency and lethality. Despite public concern, policy and prevention efforts have remained limited and have not yet resulted in a decrease in these events. Understanding mass shootings as a subset of mass murder will help identify how mass shootings are unique from other mass murders, which will help to identify more effective prevention tactics. Additionally, exploring mass shooting trends in the context of homicide trends and other crime trends will illuminate patterns that can be used to inform policy and prevention …

Weighing The Costs: Understanding How Eating Disorder History And Motivation For Use Impacts Experience On A Glucagon-Like Peptide-1 Receptor Agonist And Interest In Future Use, Kimberly M. Gauert

Electronic Theses & Dissertations (2024 - present)

Glucagon-Like Peptide-1 receptor agonist (GLP-1 RA) medications have become popular tools due to their effectiveness regarding weight loss and chronic disease management. The drastic increase in demand for these medications has led to widespread availability and an increase in “off-label” use for cosmetic purposes. Although GLP-1 RA medications have the potential to positively impact overall health and wellbeing, there is also concern regarding potential misuse of these medications by those with a history of eating disorder behaviors. However, few studies to date have examined the relationship between a history of eating disorder pathology, reason for GLP-1 RA use, and current …

Genetic Diversity Of Cryptosporidium Species In New York State, Kimberly A. Mergen

Electronic Theses & Dissertations (2024 - present)

The knowledge regarding Cryptosporidium infections in New York State (NYS) is severely lacking in two ways: 1) there are currently no NYS-based data regarding the subtypes of Cryptosporidium parvum and Cryptosporidium hominis, which are the two most prevalent species that infect humans and 2) information regarding uncommon Cryptosporidium species that infect the New York population is also unavailable. Filling these gaps concerning this pathogenic parasite would provide a substantial amount of information when considering public health, outbreak investigations, and prevention measures. Therefore, improving Cryptosporidium subtype and species surveillance in NYS will aid in prevention and control efforts as well …

Access To Appropriate Care, Mortality, And Cost Of Inpatient Hospitalization In Infants With Omphalocele And Gastroschisis In The United States, Treeva A. Jaff

Electronic Theses & Dissertations (2024 - present)

Congenital abdominal wall defects (AWDs), including omphalocele (OM) and gastroschisis (GS), are rare but clinically significant conditions that require immediate surgical intervention and prolonged neonatal intensive care. OM is a midline defect in which abdominal organs protrude into the umbilical cord covered by a membranous sac, while GS is a full-thickness defect typically located to the right of the umbilicus through which organs protrude without protective coverage. OM is frequently associated with major co-occurring congenital anomalies and chromosomal abnormalities, while GS more commonly occurs as an isolated defect but requires more intensive surgical management. As survival rates have improved, research …
