Large Language Models (LLMs), with their ability to comprehend and generate programming codes have shown promising results in the automatic identification of errors. This can potentially benefit student programmers by providing them with timely formative feedback at efficiencies and scale that were not attainable previously. In this study, we leveraged an LLM - OpenAI o4-mini for the generation of elaborated, targeted feedback for novice programmers across PHP and JavaScript exercises. We contend that the feedback needs to be effective and targeted other …

Selective Concolic Testing, Guofeng Zhang, Zhenbang Chen, Ziqi Shuai, Jun Sun, Weijiang Hong, Yufeng Zhang, Ji Wang, Yang Liu

Research Collection School Of Computing and Information Systems

The principled combination of symbolic execution and random testing lacks a formal foundation, especially in deciding which inputs to symbolize. We propose selective concolic testing, a cost-aware framework that formulates this choice as an optimized policy problem of a MDP (Markov Decision Process). We model program exploration over a finite control-flow graph, where MDP states represent covered statements, actions partition path constraints into symbolic and random fragments, rewards reflect coverage gain, and costs account for SMT solving effort and sampling inefficiency. Our framework yields the first formal characterization of selective symbolization as policy synthesis in a probabilistic system. We prove …

Associations Between Controlling Coaching Behaviors And Mental Health Help Seeking Attitudes In Collegiate Athletes, Maria C. Cacheiro

Undergraduate Honors Theses

Although correlations between coaching behaviors and mental health have been investigated before, research that extensively analyzes collegiate athletes’ willingness to seek out mental healthcare has not been conducted. Previous research shows that coaching behaviors correlate with athlete mental health and even predict depression levels more accurately than their own personality traits. The current study aimed to analyze the relationship between athletes’ perceived controlling coaching behaviors and their mental health-help seeking attitudes. Participants were surveyed to determine their perception of controlling coaching behaviors, available emotional support, athlete-coach relationship satisfaction, and mental health seeking attitudes. It was found that perceived aspects of …

Transform-Based Quantum Potential Reconstruction From Sparse Spectral Data: Generalized Bertlmann-Martin Moment Inequalities, Matthew Plott

Masters Theses and Doctoral Dissertations

Inverse quantum problems ask whether a central potential V(r) can be reconstructed from limited spectral information under explicit modeling assumptions. This dissertation develops and validates a reproducible, transform-based framework for reconstructing ground-state radial densities rho(r) = |R(r)|^2 and central potentials V(r) from discrete bound-state energy levels using generalized Bertlmann-Martin (GBM) moment inequalities as physics-informed constraints. In the Laplace route, L(q) is assembled from moment data and inverted numerically to recover rho(r). In the Fourier/form-factor route, even moments determine F(q) and inverse transformation yields rho(r). To support sparse spectral inputs, analytic continuation is performed with Pade approximants, and the framework is …

Loneliness And Social Support In Shift Work Employees, Jacob Lamprecht

Masters Theses and Doctoral Dissertations

Loneliness, a discrepancy between the desired quantity and quality of one’s relationships and their current relationships, has been connected to increases in mortality, as well as lower job performance, reduced job satisfaction, and increased burnout. However more recent studies indicate that the recipient may not always perceive the support as beneficial, resulting in “unhelpful social support. The present study examined how helpful and unhelpful social support relate to loneliness among healthcare shift workers, a population that may be prone to fatigue and health risks. I hypothesized that helpful support would be negatively related to loneliness and that unhelpful support would …

Supervisor-Focused Impression Management And Social Undermining As Self-Enhancing Responses To Perceived Job Insecurity, J. Luke Wiley

Masters Theses and Doctoral Dissertations

Job insecurity has become a more prevalent and harmful issue across many advanced economies. The present study was designed to investigate two ways in which employees may respond to perceived job insecurity. We hypothesized that employees experiencing job insecurity engage in impression management tactics directed at their supervisor (SFIM) or social undermining tactics directed at their coworkers. We further hypothesized that these processes or effects were moderated by employees’ core self-evaluations (CSE). Data were gathered through targeted sampling to workers in the federal government (Sample 1, N = 91), as well as convenience sampling (Sample 2, N = 146). Results …

This process yielded a confident sample of 910 sources exhibiting at least one periodic signal, hereafter referred to as the Cataclysmic Variable Confident Catalogue (CCC). For each object, we report the most likely orbital period together with …

Fructose: Metabolic Signal And Modern Hazard, Richard J Johnson, Miguel A Lanaspa, Dean R Tolan, Marcus D Goncalves, Samir Softic, Kimber L Stanhope, Laura G Sánchez-Lozada, Mark A Herman, Joshua D Rabinowitz

Faculty, Staff and Students Publications

There is much interest in the role of sweeteners such as table sugar (sucrose) and high-fructose corn syrup in obesity and metabolic disease. Both sweeteners consist of glucose and fructose, two six-carbon isomeric sugars. Whereas glucose ingestion may promote obesity through its effects to stimulate insulin secretion, fructose has unique metabolic effects that promote triglyceride synthesis and fat accumulation. These effects arise from fructose's well-known role as a signal of metabolic plenty. Under modern conditions of overnutrition, chronic excess fructose drives features of metabolic syndrome. Emerging evidence further links fructose to cancer and dementia. Here we review the biochemical, molecular …

A Phenomenological Study Of Teachers Who Use Oral Reading To Foster Student Reading Fluency And Engagement, Donyetta Grimes

Dissertations

The National Reading Panel (2000) recommends oral reading instruction as a means to improve overall reading fluency and reading comprehension. Oral reading fluency is a necessary foundational skill, and students who have not mastered it by the end of third grade, when students transition from learning to read to reading to learn, become struggling adolescent readers (Ming, 2018). Furthermore, there is a lack of research on reading fluency past the primary grades (Makebo et al., 2022). Additionally, research gaps exist when considering teachers’ actual practices during reading instruction (O’Sullivan et al., 2009). This gap is particularly concerning considering that teachers …

Restorying The Reader: Adolescent Narratives Of Identity, Context, And Motivation, Jennifer R. Gardner

Dissertations

This present study examined how adolescents narrate their reading experiences and what those narratives reveal about reading identity, motivation, and engagement. This study responds to a persistent problem in literacy education: adolescent reading is often framed through disengagement or reduced to isolated constructs, while students’ lived reading experiences across school, home, digital, linguistic, and social contexts remain underexamined. Guided by Self-Determination Theory, Intersectionality, and Reader Response Theory, this study centers on adolescent voices and treats these participants’ stories as the primary avenue of understanding how they experience and interpret their reading lives and selves. Data were collected through narrative interviews, …

This study examined the association between fathers' diet quality patterns during their adolescence and food parenting practices during fatherhood.

Methods: Data were drawn from Fathers & Families (F&F), a father-based cohort that recruited participants from an ongoing cohort in the United States that has followed participants since adolescence. Participants (n = 584) reported their dietary intake during adolescence (ages 10-18) using a Youth/Adolescent Food Frequency Questionnaire across multiple survey waves (1996-2011), and reported their food …

Traumatic Stress Recruits An Excitatory Orbitofrontal-Amygdala Pathway To Drive Maladaptive Aggression, Mikaela Aholt

Theses

Traumatic stress is a reliable predictor of heightened aggression, yet the mechanisms linking stress exposure to aggression remain poorly understood. The Nordman lab previously found that traumatic stress activates the posterior ventral segment of the medial amygdala (MeApv) to drive persistent increases in aggressive behavior. However, why traumatic stress would engage an aggression-promoting pathway is unclear. To address this, the inputs to the MeApv were mapped and a population of excitatory, but not inhibitory, neurons in layer 5 of the medial orbitofrontal cortex (mOFC) were identified. The OFC is classically viewed as an inhibitory brake on amygdala-driven impulses, yet emerging …

Evaluation Of Otolith Microchemistry For Identifying Walleye Stocked As Fry Or Fingerlings, Joshua Fluur

Theses

Walleye (Sander vitreus) is a popular sport fish whose populations are often supported by maintenance or supplemental stocking, with most fish stocked as fry, fingerlings, or advanced fingerlings. Evaluation of stocking efficacy is important to inform decisions regarding fish stocking rates and sizes and allocating hatchery fish to locations where maintenance or supplemental stocking is most needed. Several types of artificial tags or marks have been proven useful in the identification of stocked fish, but they often have various drawbacks. Natural chemical markers in otoliths offer several advantages compared to conventional tags or marks and can be used to identify …

The Making Of Shi'a Resistance In Afghanistan: Historical Roots, Communist Rule, And Soviet Occupation, 1978–1989, Sayed Sajjad Hojet

Theses

This thesis examines Shi'a political mobilization in Afghanistan from the 1978 Saur Revolution through the Soviet occupation, ending in 1989. It argues that Shi'a resistance was not simply a religious reaction to Marxist rule but a complex movement shaped by long-term marginalization, influenced by rival political ideas, and connected to cross-border networks in Iran. It traces how persecution under Amir Abdurrahman Khan created a system of political exclusion that shaped Shi'a collective identity before the communist takeover, and how ideologies such Marxism and Political Islam further politicized Shi'a youth in the mid-twentieth century. The PDPA's coercive policies after 1978 helped …
