Too Much Of A Good Thing? Can Students Be Too Behaviorally Engaged, Rosemary Louise Odem

Theses and Dissertations

Student engagement in school is a key determinant of students’ academic success. Student engagement is commonly conceptualized as a meta construct comprised of three dimensions: emotional, cognitive, and behavioral engagement (Fredricks, 2015). Behavioral engagement, the focus of this study, is defined by positive conduct, involvement in learning and academic tasks, and participation in school-related activities (Fredricks et al., 2004). Some researchers have suggested that psychological strengths, like engagement, can be overused and result in maladaptive consequences (Niemiec, 2019; Oishi et al., 2007). This study addressed this notion using archival data from a sample of 422 students from one Southeastern US …

Strategies For Developing Mathematical Identities In Middle School Students, Margaret M. Stevens

Theses and Dissertations

This concurrent mixed-methods action research study investigated the impact of mathematical discourse intervention on seventh-grade students’ mathematical identities and understanding. Twenty students participated in a four-week intervention implementing Smith and Stein’s (2018) five practices plus one framework.

Quantitative results showed curriculum-based assessments improved significantly (p < .001, d = 1.64). State mathematics assessment revealed minimal change in mean scores. The Mathematical Identity Questionnaire revealed positive shifts across all five constructs, with largest gains in Mathematical Initiative (+0.40) and Problem-Solving Persistence (+0.30). Qualitative analysis using Bingham’s (2023) five-phase process revealed three themes: Mathematical Voice Development, Identity Transformation Through Competence Building, and Communal Validation. Social Cognitive Theory and Culturally Relevant Pedagogy integration showed how discourse interventions addressed both individual self-efficacy and systemic inequities. Findings suggest intensive discourse intervention can initiate positive changes in mathematical identity and understanding for struggling students. Implications include restructuring mathematics instruction to prioritize student discourse and voice, creating more equitable learning environments.

Gut Microbiome Dynamics In Heart Failure And The Therapeutic Potential Of Nmeg-Cgrp, Kamryn Michael Gleason

Theses and Dissertations

Heart failure (HF) is increasingly recognized as a multisystem disease often linked to gut dysbiosis; however, its specific effects on gut microbial composition remain poorly understood. This study examined long-term changes in the gut microbiome in a murine HF model induced by transverse aortic constriction (TAC) and evaluated the effects of NMEG-CGRP. TAC mimics pressure overload-induced cardiac dysfunction, replicating key features of HF. CGRP, a neuropeptide with vasodilatory and cardioprotective effects, shows potential as a therapy for HF but is limited by rapid degradation. A stabilized analog, NMEG-CGRP, was used to assess its impact on cardiac and gastrointestinal health. Mice …

Spectral Modeling Of Electromagnetic Radiation From Power Converters, Regan A. Varner

Theses and Dissertations

Switching power converters are increasingly utilized in contemporary electronics. They are becoming more compact and operate at higher frequencies, which contributes to radiated electromagnetic interference (EMI). This EMI is important to quantify for electromagnetic compatibility of the converters with other nearby systems. In this thesis, analytical models have been developed for both ideal and non-ideal switching waveforms, employing piecewise functions to describe time-domain waveforms, with their corresponding frequency spectra derived and compared to empirical spectra. The results demonstrate that the comparisons with measured frequency data exhibit agreement with the analytical models up to approximately 25 MHz. Additionally, our analysis indicates …

The Moderating Effects Of Community Involvement On The Association Between Witnessed Community Violence And Mental Health Outcomes Among Black Adolescents, Curtisha Tamara Shacklewood

Theses and Dissertations

Black youth and adolescents are at a disproportionately high risk for experiencing community violence exposure (CVE) and the potential influence it may have on psychological functioning. Research posits that Black youth who experience community violence are at a significantly higher risk of experiencing elevated internalizing symptoms (e.g., depression) and externalizing symptoms (e.g., delinquency). Previous research has utilized the ecological model to investigate interpersonal protective factors that potentially buffer the effects of CVE, including parental support and family characteristics. However, there is little research that explores community-level factors, such as community activities (e.g., youth activities and parental perception of collective efficacy) …

The Role Of Fibroblast Activation Protein On Left Ventricular Growth And Extracellular Matrix Remodeling As A Function Of Age And Pressure Overload, Amelia Marie Churillo

Theses and Dissertations

Fibroblast activation protein (FAP) is abundantly expressed in cancer associated fibroblasts and contributes to extracellular matrix (ECM) remodeling. Recent studies using imaging techniques have identified increased levels of FAP in the left ventricle (LV) of patients identified as at risk for developing heart failure. However, the role of FAP in regulated LV myocardial structure and function remains unclear. This project tested two hypotheses: First, genetic ablation of FAP would modify LV structure and function and be more pronounced with aging. Second, genetic ablation of FAP would modify LV structure and function with LV pressure overload (LVPO) accompanied by ECM remodeling.

Examining The Effects Of Firearm Lethality And Aggressors’ Intentions To Kill On Injurious Firearm Violence At American Schools: A Research Note, Brent R. Klein, Cory Schnell, Steven M. Chermak, Joshua D. Freilich

Faculty Publications

This study examined firearm lethality and aggressors’ lethal intent on injurious fatal and nonfatal school shootings using data from The American School Shooting Study, which covers 329 school shootings in the United States from 1990 to 2016. We developed a new multidimensional construct for measuring shooters’ determination to kill and examined firearm characteristics while considering confounding factors. We identified 11 distinct categories of shooters’ intent, with most showing a strong desire to kill. Both intent and weapon lethality significantly impacted school shooting homicides. Overall, we recommend that prevention and theoretical models should address both factors.
