The Gut-Brain Axis: Investigating The Effects Of Diet, Physical Activity, And Prior Adversity On Anxiety Via Autonomic Nervous System, Jenna L. Pennella

UNF Graduate Theses and Dissertations

Previous literature has highlighted a bidirectional relationship between the gut and brain called the gut-brain axis (de Punder & Pruimboom, 2015; Hill et al., 2008; Leistner & Menke, 2020). The current study aimed to investigate directional relations between different stressors (e.g. poor diet, vigorous activity, and prior adversity) and anxiety and how interactions with gut issues and autonomic dysfunction may impact these relationships. Based on previous literature, we examined (a) physical activity and diet as moderators of stress and anxiety as well as stress and GI symptoms, (b) GI symptoms as a mediator between various predictors (i.e., diet, stress, physical …

Urban Heat Island Effects On Arthropod Populations And Communities In Jacksonville, Fl, Eleanor G. Cronin

UNF Graduate Theses and Dissertations

The urban heat island (UHI) effect makes urban areas hotter than rural areas. Urban areas, and the extreme heat that comes with them, are becoming more common worldwide. If UHIs lead to changes in arthropod community diversity, then ecosystem structure and services could be disrupted. Previous UHI studies have investigated heat impacts on arthropod ecology, but many focus on one species while studies that consider thermal diversity within a single urban area have been limited. In Jacksonville, Florida, areas that are 12°C hotter than the coolest areas are considered local UHIs. The goal of this research is to investigate how …

Use Of Coelomic Fluid As A Noninvasive Indicator Of Reproductive Status In Elasmobranchs, Emily Sapp

UNF Graduate Theses and Dissertations

Information on reproduction in elasmobranchs is important for the management and conservation of populations. However, the ability to obtain reliable data on elasmobranch reproduction without animal euthanasia is extremely limited. Therefore, there has been a call for nonlethal approaches for identifying reproductive status of elasmobranchs. Although useful, current techniques can be limited with respect to access to equipment and reliability of blood analyses. This study investigates whether a new noninvasive approach, the examination of coelomic fluid (CF), can provide a reliable indicator of reproductive status. CF is fluid that bathes the internal organs of the abdominal cavity, including ovaries, and …

Dynamics Of Prey-Prey Mutualism With Varying Carrying Capacity And Herd Behavior In The Presence Of Predator, Felix Dela Djokoto

UNF Graduate Theses and Dissertations

This study investigates the dynamics of mutualistic relationships between two prey species in the presence of a predator, by taking into account herding in one species along with the influence of carrying capacities between two prey species. These mutualistic dynamics are presented by constructing two mathematical models, namely an indirect and direct mutualism model. As the strength of the symbiotic relationship increases the indirect model goes through transcritical bifurcation to Hopf bifurcation whereas in the direct mutualism model goes through saddle-node bifurcation to Hopf bifurcation.

Diversity Makes Me Uncomfortable: Effects Of Diversity Language On University Student Belonging, Ziena Baker

UNF Graduate Theses and Dissertations

Diversity statements and experiences form the first impressions students have of their prospective universities and employers, setting the stage for perceived feelings of belonging, otherness, and comfort within new environments (Baleria, 2021; O’Keeffe, 2013; Starck et al., 2021). Diversity statements can signal feelings of comfort and belonging or feelings of stress depending on the way in which diversity is framed (Chaney, 2022; Trawalter et al., 2016). This is especially true for students, who are more often affected mentally and physically by changes in university diversity perspectives (Sladek et al., 2021) The current study thus uses a novel blood pressure measure …

The Stochastic Occupation Kernel (Sock) Method For Learning Stochastic Differential Equations, M. L. Wells, Kamel Lahouel, Bruno Jedynak

Mathematics and Statistics Faculty Publications and Presentations

We present a novel kernel-based method for learning multivariate stochastic differential equations (SDEs). The method follows a two-step procedure: we first estimate the drift term function, then the (matrix-valued) diffusion function given the drift. Occupation kernels are integral functionals on a reproducing kernel Hilbert space (RKHS) that aggregate information over a trajectory. Our approach leverages vector-valued occupation kernels for estimating the drift component of the stochastic process. For diffusion estimation, we extend this framework by introducing operator-valued occupation kernels, enabling the estimation of an auxiliary matrix-valued function as a positive semi-definite operator, from which we readily derive the diffusion estimate. …

Assessing The Relationship Between Perceived Psychological And Physical Pain In Adults With Orthopedic Pain, Daniel C. Karimi Dehkordi

Honors Undergraduate Theses

Suicide remains a public health concern in the U.S., particularly among individuals experiencing chronic pain and psychological distress. This cross-sectional study investigated the relationship between perceived physical and psychological pain in 41 adults with chronic orthopedic conditions. The relationship between other risk and protective factors and perceived levels of pain distress was also examined. Results showed a significant positive correlation between psychological distress and physical pain (r(39) = 0.388, p < .05) and psychological distress and depressive/anxiety symptoms (r (39) = 0.477, p < .01). Psychological distress was moderately associated with feelings of hopelessness (r (39) = 0.403, p < .01), however, the relationship between physical pain and hopelessness was weak and nonsignificant (r (39) = -0.06, p = .71). Contrary to expectations, emotional support did not buffer the effects of psychological distress (r (39) = 0.07, p = 0.66). Mediational analysis confirmed that emotional support did not influence the relationship between physical pain and psychological distress (Beta (β) = -0.969, p = 0.572; Sobel Z = 0.5598, p = 0.575). Age was not correlated with psychological distress (r (39) = -0.24, p = 0.13) or mental health symptoms (r (39) = -0.05, p = .77). While there was no significant difference across sex, males reported higher mental health symptomatology and psychological distress scores than female counterparts. These findings underscore the direct impact of physical pain on psychological distress and challenge assumptions about the protective role of social support. The study highlights the need for integrated, multidisciplinary interventions targeting both physical and psychological pain to mitigate suicide risk among individuals with chronic orthopedic conditions. Future research should iii explore alternative support mechanisms and resilience-building strategies to address the complex interplay of pain, distress, and suicidality.

The Intersection Of Autism Spectrum Disorder And Mental Health: A Focus On College Students, Sudeepta Matha

Honors Undergraduate Theses

Rising prevalence rates of autism spectrum disorder (ASD), changes in diagnostic criteria, and increased public awareness have all contributed to the growing population of college students with ASD. However, many individuals - commonly referred to as the “lost generation” - go undiagnosed, due to experiencing negative interactions with mental health professionals. As a result, these individuals are not given the proper support and interventions required for a successful transition into adulthood, and often face heightened social isolation, academic problems, mental health challenges compared to their neurotypical peers. A combination of these factors can lead to increased suicidal ideation (SI) and …

Anxiety And Adaptive Functioning In Young Adults: The Moderating Role Of Psychological Flexibility, Makenzie L. Kennedy, Jeffrey E. Cassisi

Honors Undergraduate Theses

Anxiety is highly prevalent among emerging adults and is associated with impairments in academic, social, and daily functioning. While previous research has documented strong associations between anxiety and adaptive functioning, the present study uniquely tested psychological flexibility as a potential moderator that may foster resilience and adaptive coping.

Undergraduate students (N = 522) from the University of Central Florida completed measures of anxiety (PROMIS-A, GAD-7, STAI-S), adaptive functioning (WHODAS 2.0), and psychological flexibility (COMPACT-23). Confirmatory factor analyses supported distinct but correlated latent constructs of anxiety and adaptive functioning. Due to poor subscale intercorrelations, the COMPACT-23 total score was modeled as …
