Polyphenol-Protein Interactions In Pigmented Cereals – A Clean-Label Approach To Tailor Starch Viscosity, Annegret Jannasch

Graduate Theses and Dissertations

Viscosity plays an important role in the food industry as it affects the quality, processing stability, and shelf-life of food and impacts physiological responses such as satiation and satiety. Greater viscosity reduces food intake by increasing the perception of satiety, primarily by delaying gastric emptying and increasing tactile stimulation. Starch is commonly added to food products as a viscosifying ingredient, which often involves chemically modifying the starch via cross-linking, to enhance its resistance to high shear, temperature and acidity. However, chemically modified starches are not “clean-label” ingredients due to the use of toxic chemicals. Therefore, further exploration is needed to …

Quantifying The Effects Of Urbanization On Stream Nutrient Loads And Decomposition, Caroline Anscombe

Graduate Theses and Dissertations

Urban stream syndrome (USS) refers to the common symptoms of degradation in urban streams globally. Two symptoms of USS are increased nutrient and salt concentrations in streams, affecting ecosystem structure and function. Excess nutrients negatively impact freshwater ecosystems, placing downstream habitats at risk of eutrophication and harmful algal blooms. Excess salt runoff, derived from road salt application, is toxic to freshwater organisms and affects leaf litter decomposition, the base of aquatic food webs. Here, I aimed to quantify the effects of nutrient pollution and salinization on urban water quality and ecosystem function. Despite the widespread consequences of nutrient pollution, most …

From Adolescence Into Adulthood: How Exclusionary Discipline And Sex Impact Early Adulthood Social And Economic Opportunities, Madeline Shanahan

Achieving Flexible Fairness And Privacy In Federated Learning, Alycia N. Carey

Graduate Theses and Dissertations

Having access to large, high-quality datasets is crucial for training machine learning models that achieve satisfactory performance. Unfortunately, it is common that a single entity (e.g., mobile device or organization) does not have access to such datasets due to monetary or resource constraints. Traditional machine learning requires that all training data reside in a centralized location during the entire duration of model training, however, in many circumstances it is difficult or even impossible (e.g., due to governmental regulations) for multiple parties to combine their data to meet this constraint. Federated learning is a machine learning paradigm that facilitates the joint …

Geospatial Modeling Of Winter-Related Property Damage In Arkansas, Braedyn Mcbroom

Graduate Theses and Dissertations

Storm Data, a monthly publication by the National Weather Service with records of weather events, reports on property damage caused by natural hazards. Since 1996, the database has included winter-related events. While the property damage data is considered incomplete, no other unique, public datasets report winter-related property damage at the county level. From 1996 to 2024, Arkansas ranked #1 in winter-related property damage. To understand the factors that are driving property damage and potentially reduce Arkansas’ vulnerability to it, three groups separated by temporal periods, i.e., “2000” (01/1996 - 06/2005), “2010” (07/2005 - 06/2015), and “2020” (07/2015 - 06/2024) …

An Instructional Remodel: How Adopting A Unifying Model-Of-Instruction Impacted Teacher Self-Efficacy And Teacher Development And Evaluation Efforts In A Midwestern High School, Charles D. Patterson Carpenter

Graduate Theses and Dissertations

This mixed methods study sought to determine the effect of adopting a unifying model-of-instruction on teacher self-efficacy and the development and evaluation processes of administrators. By assessing the level of teacher self-efficacy (Tschannen-Moran & Hoy, 2001) in the nascent stages of the instructional model’s implementation, then reassessing it after a multiple-month sequence of professional learning, the researcher provides a judgment on statistical significance concerning the two measurements and conjectures the extent to which the instructional model impacted any differences in self-efficacy levels. Using two separate “before and after” interviews with purposefully selected administrators, the researcher explored how the unification of …

Real Time Adaptive Control Of A Pid Via Genetic Algorithm Machine Learning Systems, Cemre Tas

Graduate Theses and Dissertations

The most common control method that is utilized by all industries across the world is the proportional-integrative-derivative controller (PID) due the relatively low cost and complexity of the system. However, there are draw-backs with PIDs, it is not adaptative to a changing system, so it works on nominal systems, and it starts breaking down when a system begins to have a non-linear response. The method chosen to overcome both is the utilization of machine learning with the use of genetic algorithms.

This method allows any PID system to be capable of adapting in real-time, while not adding significant additional cost …

Controls On Nutrient And Sediment Export In A Non-Perennial Agricultural Stream, Kathleen Cutting

Graduate Theses and Dissertations

Climate change is expected to increase flow variability and intermittency in streams, changing the magnitude and timing nutrient and sediment delivery. This may exacerbate water quality issues in agricultural landscapes, where nutrient and sediment inputs are often elevated. Elevated nutrients can drive eutrophication in downstream waterways, and excess sediment loss can decrease primary productivity. Non-perennial headwater streams are particularly vulnerable to the impacts of climate change and agriculture as they serve as key sites for nutrient cycling at the terrestrial-aquatic interface. Despite their importance, the interactive effects of agriculture and stream intermittency, as well as unpaved roads in rural watersheds …

Immune Response To Long-Term Lipopolysaccharide Infusion In Sheep, Laura A. Centanni

Honors Scholar Theses

Poor maternal nutrition (restricted and over-feeding) during gestation alters metabolism, growth, and body composition of offspring. It may also affect immune function. The purpose of this study is to determine the safety and efficacy of long-term immune challenge using lipopolysaccharide in sheep. Through two challenge weeks, each consisting of five days of lipopolysaccharide treatment, monitoring, and data collection, the treatment was found to be safe in sheep and effective to elicit an immune response. The data from this study will inform future studies on maternal nutrition in the University of Connecticut Animal Science Department.

The Effect Of Non-Profit Organizations On The Passage Of Climate Change Legislation In Connecticut, John-Henry Burke

Honors Scholar Theses

Connecticut has a long history of climate action. In this study, I looked into the effect that non-governmental organizations have on the passage of climate change legislation in Connecticut. Eighteen different climate policy stakeholders, including legislatures, non-governmental organization (NGO) staff members, youth activists and state employees were interviewed to gain their perspective on how non-profits forward climate initiatives. I found that non-profit organizations do have a significant impact on the passage of climate change legislation in Connecticut by working as providers of information to legislators and mobilizers of constituents. This impact can be limited by various political factors.

Post-Secondary Educational Interventions For Youth Aging Out Of Foster Care: A Systematic Review, Catherine Ware

Honors Scholar Theses

Youth with experience in foster care (YEFC) face significant educational disparities, with only a small fraction completing postsecondary education compared to the general population. These disparities stem from a complex interplay of adversities including placement instability, financial insecurity, trauma, and lack of support systems. In recent years, campus-based support programs (CSPs) have emerged to address these barriers and promote college access and success for YEFC. This systematic review synthesizes findings from 10 studies examining 15 CSPs across the United States, with a focus on (a) student perceptions of program experiences and (b) educational outcomes associated with program participation. Results indicate …

Signal Modeling Of High Purity Germanium Detectors, Brooke Parker Thibodeau

Honors Scholar Theses

Pulse shape analysis can be used to analyze radiation incident on a semiconductor diode detector. Finite element analysis (FEA) can be used to simulate high purity germanium detectors with user-specified geometry, impurity concentration, and bias voltage. Subsequent streamline calculation can be used to conduct pulse shape analysis for single and multiple site gamma-ray interactions within the detector volume. Cross sections of the detector can be visualized by contour plots of the electric field, drift velocity magnitude, and collection time, as well as t30 and t90 rise-time values.

Characteristics Of Shallow Convection In Diverse Coastal Conditions, Zackary Mages

Electronic Dissertations and Theses, 2010-current

Clouds are an important component of Earth’s climate system. In particular, shallow convective clouds contribute to the vertical transport of heat, moisture, and momentum in the troposphere, and they generally have a net cooling effect on the planet’s radiation budget. Previous studies have often been limited by a lack of large observational samples needed to understand these clouds and their characteristics. This dissertation strives to overcome this limitation by analyzing observations of shallow convective clouds in two different coastal regions and using two different measurement paradigms. First, shallow convective clouds generated by cold-air outbreaks on the northern coast of Norway …

Manuscripts, Articles, Book Chapters and Other Papers

Public transportation can lead to increases in physical activity, access to jobs, healthcare, and healthy food, and may improve overall health. Funding for public transit is essential for a sustainable transportation system. However, most health studies have not focused on voting behavior as a mechanism for sustaining public transportation. This study employs a cross-sectional, in-person, exit poll of voters at 10 randomly selected polling locations during a local election in 2023 in Kansas City, Missouri. The voter ballot included a question to extend an existing 3/8 cent sales tax for public transportation. Participants (N = 649) overwhelmingly supported (90.6 %) …

Making Tabby, Making Place: Examining A Gullah Geechee Wattle And Tabby Daub Dwelling Through Thin Section Analysis, Jacob E. Hamill

Graduate Masters Theses

Tabby is a building material made from lime, sand, oyster shell, and water that is geographically associated with the Sea Islands of South Carolina, Georgia, and Florida. This material was used from the early 18^th century to end of the American Civil War to construct all-manner of buildings in the Sea Islands region. Enslaved African descendant communities constructed wattle and tabby daub dwellings within plantation landscapes, and these settlements are interpreted as spaces where enslaved people exercised greater spatial autonomy.

This thesis analyzes the remains of a wattle and tabby daub structure located on what was once Old Fort …
