Probabilistic Modeling Of Disease: Addressing Uncertainties In Within-Host And Population-Level Dynamics, Mariah Boudreau
Probabilistic Modeling Of Disease: Addressing Uncertainties In Within-Host And Population-Level Dynamics, Mariah Boudreau
Graduate College Dissertations and Theses
Mathematical modeling of disease dynamics provides powerful tools to understand, predict, and evaluate emerging diseases. These insights aid public health officials, along with other modelers. With a plethora of models to choose from, it is important to consider a model that encapsulates the stochastic nature of disease dynamics. Stochasticity not only conveys chances of stochastic extinction, but provides probabilistic outcomes, essential for capturing the stochastic nature of the real world. In this thesis, three stochastic models are presented, each addressing uncertainties in mechanisms and interpretation of these models, to aid other modelers and decision makers.Starting with the source of infection …

Community Transitions Of Care For Hospital Readmission Prevention, Lauren Fedorka
Community Transitions Of Care For Hospital Readmission Prevention, Lauren Fedorka
College of Nursing and Health Sciences Doctor of Nursing Practice (DNP) Project Publications
Background: Transitions of Care (TOC) occur whenever an individual moves from one healthcare setting to another. Older adults are higher utilizers of healthcare services, including inpatient and emergent visits, than the general population (Tian, 2016), and thus experience more TOCs. Due to risk of poor outcomes at discharge from the hospital, rehospitalizations are a concern. Standardized TOC protocols have been shown to be beneficial in reducing rehospitalizations for this vulnerable population.
Purpose: Use current best practices to design and implement TOC for a rural community organization to reduce unintended rehospitalizations for older adults.

Timeseries Analysis To Characterize Complex Phenomena In Environmental And Human Health Applications, Jeremy Ernest Matt
Graduate College Dissertations and Theses
Studying and evaluating time series signals that emerge when monitoring complex phenomena requires fusing, visualizing, and often reducing the dimensionality of large amounts of data to reveal the patterns and relationships that appear at different scales. In this work, we develop methods for monitoring, visualizing, and identifying the complex relationships that appear in time series data collected from two very different domains – health care conversations and river networks – to facilitate large-scale understanding of these systems. Fostering connection between clinicians and patients and their families in the context of serious illness is a fundamental component of good clinical communication …
Investigating The Effects Of Medroxy-Progesterone And Hormonal Birth Control On Habit Behavior In Female Rats, Sarah Charlotte Von Doepp
Investigating The Effects Of Medroxy-Progesterone And Hormonal Birth Control On Habit Behavior In Female Rats, Sarah Charlotte Von Doepp
Graduate College Dissertations and Theses
Recent research has shown that there is a significant sex difference in the rate of habit acquisition in rats, with intact females acquiring the behavior with fewer action-outcome reinforcer pairings than intact males. This difference is shown to be related to the presence of cyclic estrogen and progesterone during habit behavior acquisition training. Specifically, the presence of progesterone has been shown to be crucial in early habit acquisition. However, the mechanism of action through which progesterone is influencing this behavior is unknown. Additionally, this project explores the impacts of long-term hormonal (levonorgestrel - progestin based) birth control on habit behavior …

The Effect Of Tryptamine Producing Bacteria On Gut Motility In Mice, Emilia Sofia Norberg
The Effect Of Tryptamine Producing Bacteria On Gut Motility In Mice, Emilia Sofia Norberg
Graduate College Dissertations and Theses
It has become increasingly clear that there is bidirectional communication between the microbes that exist in the lumen of the gastrointestinal (GI) tract and the nervous system. Research within the last 20 years has revealed GI bacterial metabolites to have a significant effect on gut motility, and some of these actions involve influencing serotonin signaling in the epithelial layer of the intestines. Serotonin, abbreviated as 5- HT, has many functions within the gut including propulsive and segmentation motility, vasodilation, and epithelial cell secretion. There are several bacterial species that have been discovered to synthesize one of 5-HT’s precursory molecules, including …
Quantifying Glial-Glial Interactions In Drosophila Using Automated Image Analysis, Gabriela Salazar Lopez
Quantifying Glial-Glial Interactions In Drosophila Using Automated Image Analysis, Gabriela Salazar Lopez
Graduate College Dissertations and Theses
Imaging is an immensely powerful tool in biomedical research. Technological advances in the last half century have led to the development of new tools for image analysis, with major strides being made in the last 20 years especially with machine and deep learning. However, researchers still often hit a bottleneck during the image analysis phase of their projects that often leads to delays and sometimes even limits the scope of their studies. In this thesis I demonstrate some of the issues that arise while quantifying images to answer a biological question by using a dataset of fly central nervous system …
Bayesian Experimental Design For Control And Surveillance In Epidemiology, Bren Case
Bayesian Experimental Design For Control And Surveillance In Epidemiology, Bren Case
Graduate College Dissertations and Theses
Effective public health interventions must balance an array of interconnected challenges, and decisions must be made based on scientific evidence from existing information. Building evidence requires extrapolating from limited data using models. But when data are insufficient, it is important to recognize the limitations of model predictions and diagnose how they can be improved. This dissertation shows how principles from Bayesian experimental design can be applied to surveillance and control efforts to allow researchers to get more out of their data and direct limited resources to best effect. We argue a Bayesian perspective on data gathering, where design decisions are …
An Exploration Of Reinstatement After Extinction Of A Conditioned Taste Aversion, Noelle Loren Michaud
An Exploration Of Reinstatement After Extinction Of A Conditioned Taste Aversion, Noelle Loren Michaud
Graduate College Dissertations and Theses
Taste aversion learning has sometimes been considered a special form of learning. The unique way in which the taste of a poisonous food and its gastrointestinal consequences may typically occur in nature might encourage the evolution of a unique and biologically adaptive learning system. Six experiments were designed to address whether reinstatement, a well-known effect that occurs after extinction, can be observed in taste aversion learning. After a conditioned stimulus (CS) is conditioned and extinguished, reexposure to the unconditioned stimulus (US) by itself sometimes reinstates the conditioned response (CR). Reinstatement has been widely studied in fear and appetitive conditioning preparations, …
The Evaluation Of The Prokinetic Action Of A Luminally Restricted 5-Ht4 Receptor Agonist In Mice, Emma Schoeling
The Evaluation Of The Prokinetic Action Of A Luminally Restricted 5-Ht4 Receptor Agonist In Mice, Emma Schoeling
Graduate College Dissertations and Theses
Serotonin (5-HT) is a neurotransmitter mainly produced in the enteric nervous system (ENS) of the gastrointestinal (GI) system. Serotonin has widespread function throughout the body including regulating mood, cognition, sleep, sex, and appetite. In the context of the gut, the monoamine modulates vasodilation, mucus secretion, pain, and peristaltic reflexes for motility. The 5-HT4 receptor is expressed on enteric epithelial cells and nerve terminals in the intestinal mucosa. The agonists available to act on these receptors are a favorable target to promote epithelial healing, recovery from colitis or constipation, and epithelial cell proliferation. The non-absorbable, luminally restricted, 5-HT4R agonist (5HT4-LA1; Takeda …
Nonlinear Relationships Between The Environment And Health, Levi N. Bonnell
Nonlinear Relationships Between The Environment And Health, Levi N. Bonnell
Graduate College Dissertations and Theses
Relationships between the environment and health outcomes are complex and likely nonlinear in nature. However, until recently, most studies used ordinary linear regression to model these relationships. The overall goal of this research was to investigate nonlinear relationships between the environment and health. To accomplish this goal, we used several large, national datasets across varying populations and local environments.
Destination accessibility is an important measure of the built environment that is associated with active transport and body mass index (BMI). In the first study, we sought to determine the relationship between the density of nonresidential destinations (a proxy for walkability) …
The Role Of Dentate Gyrus Pituitary Adenylate Cyclase Activating Polypeptide (Pacap) In Contextual Fear Discrimination, Samantha Kelly Moriarty
The Role Of Dentate Gyrus Pituitary Adenylate Cyclase Activating Polypeptide (Pacap) In Contextual Fear Discrimination, Samantha Kelly Moriarty
Graduate College Dissertations and Theses
When dysregulated, neural systems important for fear behaviors can contribute to mental health disorders such as anxiety, phobias, and post-traumatic stress disorder (PTSD). In PTSD, a myriad of symptoms is possible, but a hallmark feature of the disorder is generalizing fear. This occurs when fear is experienced inappropriately in relation to the environment or circumstances. To study this behavior in rodent models, contextual fear conditioning is used. Contextual fear conditioning is a learning theory preparation where rodents are conditioned with an aversive stimulus such as foot-shock in one distinct context (A), while concurrently being exposed to a safe context (B). …
Towards A Food-Secure Future In An Era Of Uncertainty: Cultivating Resilience In Vulnerable Smallholder Food Systems, Maya Moore
Graduate College Dissertations and Theses
Smallholder food systems in sub-Saharan Africa and other tropical regions are at the crux of the “triple threat” of the Anthropocene: climate change, biodiversity loss and food insecurity. At the same time, they are considered pivotal to the global food system transformation needed to address these challenges. However, while there have been many proposed pathways to achieve desired outcomes, smallholders are often constrained in their ability to adapt and transform. Therefore, in this three-article dissertation, I use mixed methods to study traditional food security coping strategies and apply socio-psychological behavioral intention theories to understand the cognitive factors behind farmers’ decisions …
Impact Of Preexisting Autoimmune Disease On Outcomes Of Patients With Myelodysplastic Syndromes, Diego Andres Adrianzen Herrera
Impact Of Preexisting Autoimmune Disease On Outcomes Of Patients With Myelodysplastic Syndromes, Diego Andres Adrianzen Herrera
Graduate College Dissertations and Theses
Myelodysplastic syndromes (MDS) are a group of heterogeneous hematologic malignancies characterized by ineffective hematopoiesis and risk of progression to acute myeloid leukemia. MDS has been linked with immune dysregulation, as overly active immunity promotes inflammation and oncogenesis within the hematopoietic system. In recent years, autoimmunity has been defined as an important pathogenic pathway in patients with MDS and numerous studies have demonstrated high prevalence of autoimmune diseases among these patients. Despite this association, the clinical and prognostic implications of preexisting autoimmune disease for patients with MDS remains to be elucidated. An important gap in knowledge is defining the effect of …
Context, Goals, And Operant Behavior: The Role Of The Prelimbic Cortex And Associated Neural Circuitry, Callum Mark Piper Thomas
Context, Goals, And Operant Behavior: The Role Of The Prelimbic Cortex And Associated Neural Circuitry, Callum Mark Piper Thomas
Graduate College Dissertations and Theses
Operant (instrumental) conditioning is a laboratory model of voluntary behavior. In its simplest form, performing a particular response, such as a lever press, leads to delivery of a reinforcing outcome (e.g., a sucrose pellet). Operant behaviors can be associated with preceding stimuli (“habits”) or outcomes (“goal-directed actions”). A factor that influences performance of operant behaviors is the context in which they are learned. Contexts can be defined as background stimuli that are present during behavior. For example, eating dessert may occur in the context of a restaurant and the sated feeling of a finished meal. The context for eating dessert, …
