Monitoring Landscape And Spectral Dynamics Of Subtropical Freshwater Wetlands That Have Undergone Hydrological Restoration, Sarah Parker Jan 2021

Monitoring Landscape And Spectral Dynamics Of Subtropical Freshwater Wetlands That Have Undergone Hydrological Restoration, Sarah Parker

Electronic Theses and Dissertations, 2020-2023

Over the last century, millions of hectares of wetlands have been lost due to urban development and agricultural activities throughout the world. In the U.S., efforts have been made by federal and state legislation to restore wetland habitat in exchange for development on wetlands. To restore ecosystem function by reestablishing hydrological metrics (e.g., groundwater level fluctuations), wetland restoration aims to facilitate the growth of wetland vegetation to approximate the original conditions as a proxy for ecological integrity. In 1992, the first landscape-scale off-site mitigation project, the Disney Wilderness Preserve (DWP) was funded by the Walt Disney Company in Poinciana, Florida. …

Modeling Of Crash Risk For Realistic Artificial Data Generation: Application To Naturalistic Driving Study Data, Lauren Hoover Jan 2021

Modeling Of Crash Risk For Realistic Artificial Data Generation: Application To Naturalistic Driving Study Data, Lauren Hoover

Electronic Theses and Dissertations, 2020-2023

Most safety performance analysis employs cross-sectional and time-series datasets, posing an important challenge to safety performance and crash modification analysis. The traditional safety model analysis paradigm relying on observed data only allows relative comparisons between analysis methods and is unable to establish how well the methods mimic the true underlying crash generation process. Assumptions are made about the data, but whether the assumptions truly characterize the safety data generation in the real world remains unknown. To address this issue, this thesis proposes the generation of realistic artificial data (RAD). In developing a prototype RAD generator for crash data, we mimic …

The Double Curse Effect Or Does Petroleum Patriarchy Affect Acceptability Of Wife Battery In Former Soviet Countries?, Karina Powell Jan 2021

The Double Curse Effect Or Does Petroleum Patriarchy Affect Acceptability Of Wife Battery In Former Soviet Countries?, Karina Powell

Electronic Theses and Dissertations, 2020-2023

Exploring social attitudes towards acceptability of intimate partner violence (IPV) is essential to understanding the nature of IPV. Attitudes justifying acceptability of wife battery may strongly predict perpetration and victimization as well as institutional responses to IPV against women. Feminist scholars emphasize that supportive attitudes towards wife beating are largely impacted by the prevalence of patriarchal values and traditional gender roles in society. Petroleum patriarchy theory suggests that oil rich countries experience greater gender inequality and have stronger patriarchal values. The current study integrates these two theories using the concept of the double curse effect. The study used mixed - …

Anti-Map Triple Therapy Supports Immunomodulatory Therapeutic Response In Crohn's Disease Through Downregulation Of Nf-Kb Activation In The Absence Of Map Detection, Erij Elkamel

Electronic Theses and Dissertations, 2020-2023

The triple antibiotic formulation, known as anti-MAP therapy, exhibits unique synergistic antimicrobial activity and should be effective for treatment of Crohn's disease (CD) associated with Mycobacterium avium subspecies paratuberculosis (MAP). The absence of MAP detection in some CD cases may be linked to poor diagnostics or lack of association with the disease. To understand the therapeutic response of some CD patients to anti-MAP therapy in absence of MAP detection, the immunomodulatory potency of anti-MAP therapy and its major ingredients, clarithromycin (CLA) and rifabutin (RIF), in THP-1, Caco-2, and Jurkat T-cells were investigated. Anti-MAP formulation at 2.0 µg/mL decreased MAP viability …

A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones Jan 2021

A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones

Electronic Theses and Dissertations, 2020-2023

The effects of roads, buildings, and cities on animal populations are widespread and, often times, disastrous. These structures fragment animals' homes, inhibiting their ability to obtain essential resources and to reproduce. The question arises then: Under what circumstances can an animal population persist in a fragmented landscape? To attempt to answer this question, we present a spatially explicit reaction-diffusion model with varying growth and diffusion rates that incorporates animal behavior at points where habitats are fragmented for four different habitats. The outcome of extinction or persistence of the animal population is determined by examining the effects of changing parameters on …

Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume Jan 2021

Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume

Electronic Theses and Dissertations, 2020-2023

An attractive strategy to improve efficacy of current Influenza A Virus (IAV) vaccines is to promote protective CD4 T cell responses. Antiviral CD4 T cell responses are predominantly classified as strong IFN-gamma producing T helper type 1 (Th1) cells. Yet, the role of IFN-gamma in protection against IAV is still unclear, suggesting absolute Th1 polarization may be expendable for effective IAV immunity. Here we test this hypothesis using models that restrict the deficiency of known transcriptional regulators of Th1 immunity in only CD4 T cells, avoiding indirect impact on other immune cell responses. We find the 'master regulator' of Th1 …

A Psychosociodevelopmental Framework For Conceptualizing The Ipv Transgenerational Cycle: The Relationships Between Maternal Mental Health, The Parent-Child Relationship, And Young Child Outcomes., J'Nelle Stephenson Jan 2021

A Psychosociodevelopmental Framework For Conceptualizing The Ipv Transgenerational Cycle: The Relationships Between Maternal Mental Health, The Parent-Child Relationship, And Young Child Outcomes., J'Nelle Stephenson

Electronic Theses and Dissertations, 2020-2023

Research suggests that following an incidence of IPV, mothers who receive adequate support are more likely to demonstrate improved mental health (Anderson & van Ee, 2018). Healthier mothers are better able to parent their young children (Andreson & van Ee, 2018), which then encourages developmentally appropriate socio-emotional behaviors in their young children. Generally, it is understood that experiences of IPV during childhood can increase the chances of IPV victimization, among other negative outcomes, in adolescence and adulthood (Priestley, 2014); thereby, contributing to the intergenerational cycle of IPV. The purpose of this study was to examine a theoretical integration connecting the …

Loss Of Control Eating Predicted By The Interaction Between Emotion Regulation Difficulties, Distress Tolerance, And The Expectancy That Eating Reduces Negative Affect, Emily Burr Jan 2021

Loss Of Control Eating Predicted By The Interaction Between Emotion Regulation Difficulties, Distress Tolerance, And The Expectancy That Eating Reduces Negative Affect, Emily Burr

Electronic Theses and Dissertations, 2020-2023

A prominent theory of binge eating is the affect regulation theory, which posits that individuals binge eat to alleviate negative affect, and subsequently reduced negative affect reinforces the behavior. Although it is well-supported that individuals experience elevated negative affect pre-binge, findings do not consistently evince reduced negative affect after binge eating. Therefore, the affect regulation theory does not fully account for binge eating. However, habitual binge eating without reliable improvement in affect may be accounted for by expectancy theory. Expectancies may be predictive of behavior whether the outcomes of a behavior are inconsistent. Additionally, there is an increasing scientific awareness …

"I Drink (Responsibly), Therefore I Am": Development Of The Personal Assessment Of Responsible Drinking Identity, Angelina Leary Jan 2021

"I Drink (Responsibly), Therefore I Am": Development Of The Personal Assessment Of Responsible Drinking Identity, Angelina Leary

Electronic Theses and Dissertations, 2020-2023

PURPOSE: Identity has long been a human phenomenon, questioned and pondered by many thinkers. Recently, changes in identity have been argued to be the driving force behind behavioral change, and therefore interventions should be viewed within the context of identity change. While several measures of a drinker's identity exist, no measure examines the idiosyncrasies of a Responsible Drinker's Identity, an aim many alcohol-related interventions target. The current study created a responsible drinker identity measure, the Personal Assessment of Responsible Drinking Identity, or PARDI. METHOD: Two studies and a follow-up were used to develop and assess the psychometric properties of the …

Modulation Of Actin Filament Severing And Mechanics By Gelsolin In Varying Ph Conditions, Claire Toland Jan 2021

Modulation Of Actin Filament Severing And Mechanics By Gelsolin In Varying Ph Conditions, Claire Toland

Electronic Theses and Dissertations, 2020-2023

Actin is an essential cytoskeletal protein that plays a critical role in cell mechanics, structure and organization with the help of actin binding proteins (ABPs). Gelsolin is a calcium-dependent ABP that severs actin filaments and caps them at their barbed end, regulating cell motility and signaling through dynamic actin cytoskeleton remodeling. A recent study has indicated that low pH stabilizes the active conformations of gelsolin. Additionally, the binding of gelsolin to the barbed end of an actin filament induces a conformational change that propagates along the actin filament. However, it has not been well understood how the complex intracellular environments …

Impact Of Crowder Size On Actin Filament Assembly Kinetics, Bryan Demosthene Jan 2021

Impact Of Crowder Size On Actin Filament Assembly Kinetics, Bryan Demosthene

Electronic Theses and Dissertations, 2020-2023

Actin is an abundant and essential cytoskeletal protein that plays a central role in eukaryotic cell structure and motility. The intracellular environment where actin assembly occurs is crowded with various organelles, proteins, and macromolecules that limit the accessible volume for biomolecular reactions. Macromolecular crowding induces excluded volume effects influencing the activity of biological molecules as well as the shape and conformation of proteins. Crowding agents, such as polysaccharides or inert polymeric molecules, are used to mimic the conditions present in intracellular spaces and provide a better understanding of interactions inside the cell. Macromolecular crowding has been shown to affect actin …

Energy-Aware Real-Time Scheduling On Heterogeneous And Homogeneous Platforms In The Era Of Parallel Computing, Ashik Ahmed Bhuiyan

Electronic Theses and Dissertations, 2020-2023

Multi-core processors increasingly appear as an enabling platform for embedded systems, e.g., mobile phones, tablets, computerized numerical controls, etc. The parallel task model, where a task can execute on multiple cores simultaneously, can efficiently exploit the multi-core platform's computational ability. Many computation-intensive systems (e.g., self-driving cars) that demand stringent timing requirements often evolve in the form of parallel tasks. Several real-time embedded system applications demand predictable timing behavior and satisfy other system constraints, such as energy consumption. Motivated by the facts mentioned above, this thesis studies the approach to integrating the dynamic voltage and frequency scaling (DVFS) policy with real-time …

Correlations In Microplastic Abundance Between Water, The Eastern Oyster, Crassostrea Virginica, And Their Biodeposits In A Dynamic Florida Estuary, Casey Craig

Electronic Theses and Dissertations, 2020-2023

Estuaries have been identified as hotspots of microplastic pollution because they are transitional zones where coastal freshwater and oceans converge. Microplastics (MP) are transported through estuaries by a dynamic series of forces such as surface flow and tides, which influence MP abundances and trends. The eastern oyster, Crassostrea virginica, is an estuarine bivalve known to ingest MP, resulting in negative impacts on organism physiology. I investigated MP pollution as a threat to C. virginica in a dynamic Florida estuary, the Indian River Lagoon (IRL), and determined there are both regional and small-scale spatial and temporal fluctuations in MP abundance. Tributaries …
