Metabolic Changes Associated With Gestational Diabetes And Weight Loss, Marykate Smith

Master's Theses

Introduction: Gestational Diabetes Mellitus (GDM) is diabetes diagnosed for the first time during pregnancy and negatively affects the mother and her child. Research suggests a multidisciplinary lifestyle intervention may aid in the reduction of GDM and its complications. Further, the use of metabolomics is needed to understand the alterations that happen prior to GDM diagnosis to reduce its recurrence.

Objective: Metabolomics analysis was conducted at baseline and 16-weeks post-intervention for women enrolled in a pre-pregnancy lifestyle intervention study to observe metabolic changes associated with GDM occurrence and weight loss.

Methodology: Sixteen samples from the parent Gestational Diabetes Prevention trial were …

Cdc’S Covid-19 Vaccination Messages And Public Engagement: A Study On Facebook Posts, Hasan Mahmud Faisal

Master's Theses

Government health agencies utilize social media for public health interventions. This study examines how CDC, the national public health agency of the United States, use Facebook to disseminate COVID-19 vaccine messages and to get public engagement towards them over the past two years (2020-2022). Investigating the process of dialogic potentials of Facebook from the dialogic theory of public relations perspective, the current study analyzes 681 posts and 3,405 comments from CDC’s official Facebook page. Thematic analysis of posts yields three dominant themes such as “Vaccine supportive”, “availability of vaccine”, and “up to date information”. Comment analysis shows positive sentiment to …

Crisis Communication In The Ukraine-Russia Conflict: Use Of Facebook By Un Humanitarian Organizations, Rubaiya Zannat

Master's Theses

The proliferation of social media has made it incredibly simple to quickly disseminate valuable information to a large audience. Thus, numerous organizations are now heavily leveraging these social networking platforms as a means for managing their crisis responses. Through a content analysis of 355 posts concerning the Ukraine-Russia conflict made by five large UN humanitarian organizations between February and May, 2022, on their official Facebook pages, this study investigated organizational crisis communication patterns. Findings suggest that UN humanitarian organizations extensively used "threat" and "need for change" as crisis characteristics to delineate the Ukraine-Russia situation, whereas “protection of safety and security,” …

Alzheimer’S Detection With The Discrete Wavelet Transform And Convolutional Neural Networks, Melissa N. Nardone

Master's Theses

Alzheimer’s disease slowly destroys an individual’s memory, and it is estimated to impact more than 5.5 million Americans. Over time, Alzheimer’s disease can cause behavior and personality changes. Current diagnosis techniques are challenging because individuals may show no clinical signs of the disease in the initial stages. As of today, there is no cure for Alzheimer’s. Therefore, symptom management is key, and it is critical that Alzheimer’s is detected early before major cognitive damage.

The approach implemented in this thesis explores the idea of using the Discrete Wavelet Transform (DWT) and Convolutional Neural Networks (CNN) for Alzheimer’s detection. The neural …

Beef Bull Selection And Management Affecting Breeding Season Outcomes For California Cattle Producers On Rangelands, Megan Banwarth

Master's Theses

California’s approximately 660,000 head of beef cattle are highly dependent on range bulls used to produce offspring that can perform across the state’s diverse ecological regions. While knowledge of bull breeding behavior and the technology used to monitor cattle movement and behavior is critical to maximize conception rates and the overall efficiency in natural service sires on rangelands. Bulls need to be functional on rugged coastal landscapes, rolling foothills, deserts, and in high-elevation terrain. Few data exist that indicate factors related to selection, maintenance, and longevity of bulls used in rangeland landscapes. Objectives herein, were to assess factors influencing bull …

Dietary Protein Intakes, Distribution Patterns, And Quality In Ncaa Divsion 1 Soccer Players, Jun H. Kwon

Master's Theses

Dietary protein is required to support recovery and adaptation following exercise training. While prior research demonstrates that many athletes meet total daily protein needs, intake seems to be predominantly skewed toward the evening meal. An even distribution of protein doses throughout the course of a day is theorized to confer greater skeletal muscle anabolism compared to a skewed pattern of intake. Protein quality is also an important dietary consideration for athletes, with the amino acid leucine being the primary driver of the postprandial anabolic response. The present thesis investigates the protein consumption characteristics among a selected cohort of NCAA Division …

Creation And Testing Of A Social Robot Guideline, Sarika L. Singhal

Master's Theses

For this thesis, I created a guideline for socially assistive robots (SARs), and used it to evaluate a reading comprehension based social robot.

To create the guideline I extracted relevant details from published standards about toy safety, radio equipment, electromagnetic compatibility, internet of things security, ethical considerations for human-computer interaction, and data privacy. I then sent a summarized version to experts in the field for feedback. I received seven responses, five of whom were from researchers in academia. The sample size was too small for statistical analysis. Survey responses identified additional areas, such as interactivity and aesthetics, for the guideline. …

Mediterranean-Style Diet And Exercise Improve Parameters For Management And Prevention Of Type 2 Diabetes Mellitus, Stefani Ann Derrick

Master's Theses

Type 2 diabetes mellitus (T2DM) is a chronic condition recognized as the inability to maintain glucose homeostasis, typically presenting with insulin resistance and systemic inflammation. With the prevalence of T2DM and major risk factors such as prediabetes and obesity increasing each year, there is a crucial need to identify strategies for the management and prevention of this condition. Addressing lifestyle-related risk factors through consumption of a well-balanced, nutritious diet and maintaining regular moderate- to high-intensity physical activity may provide a strategy for improving glycemic control, improving metrics of body composition, and decreasing the inflammatory response associated with metabolic dysregulation. Twenty-two …

From Mesoamerica To Aleppo And Transylvania: The Global Migration Of The Chile Pepper, Arianne M. Peterson, Arianne Peterson

Master's Theses

This thesis explores the migration of the chile pepper, or capsicum anuum, from Mesoamerica into the Old World after 1500, focusing on two case studies of the Aleppo pepper in Syria and paprika in what was once Hungarian Nagyvarad, and which is now Romanian Oradea. Using foodways as a historical lens, and considering the movement of food as historical, it can be seen that the chile pepper, despite its low profit value, illustrates a globalization that existed well before modern times, and it came to cement itself within many different cultures as a symbol of identity. Despite its far-away …

Stability Of Universal Screening Over Time: An Examination Of The Student Risk Screening Scale, Rebecca Wagner Lovelace

Master's Theses

Universal screening is a proactive method to identify students that are at risk for social-emotional and behavior (SEB) problems and provide information to schools to support early intervention for at risk children. Current recommendations for practice indicate screening should be conducted at three time points during the school year. Previous studies suggest that this recommendation is not empirically based and fewer screenings per year may be sufficient for identifying students at risk. The current study seeks to extend the literature regarding the stability and consistency of screening scores over time by analyzing ratings from the Student Risk Screening Scale (SRSS) …

Drinking Motives As Mediators For The Relationships Between Overparenting And Alcohol Outcomes, Tatum Freeman

Master's Theses

The present study investigated the mediating role of drinking motives in the relationship between overparenting and alcohol outcomes using a sample of 207 traditional age college students (i.e., 18-25 years old; M = 19.8, SD = 1.64). Data on participant demographics, drinking motives, the practices of participants’ primary caregiver, typical weekly drinking, hazardous drinking, and alcohol consequences were collected via SONA (an online participant management software that allows researchers to collect data from a university psychology subject pool). Participants were 89.4% female and 54.1% White. Coping and conformity drinking motives partially mediated the relationships between overparenting, alcohol consequences, and hazardous …

Plant Productivity And Diversity In Coastal Wetlands In Mississippi – Impact Of Hydrological Extremes, Kodi Feldpausch

Master's Theses

Wetlands are highly productive ecosystems that provide important ecosystem services and are threatened by extreme hydrological events. I evaluated how diversion of freshwater like Bonnet Carré Spillway openings in Louisiana, US, affected vegetation productivity and diversity in salt marshes on the neighboring Mississippi Gulf Coast, US. My study area is two estuarine systems that differ in their proximity to the Bonnet Carré Spillway, elevation, and salinity including Hancock County Marshes on the west, and Grand Bay National Estuarine Research Reserve (NERR) on the east in Mississippi. I collected above- and belowground biomass samples in 2020 and 2021, developed linear mixed-effects …

Examining The Moderating Effects Of Adult Social Support On The Relationship Between Adverse Experiences And Psychosocial Adjustment, Zachary Wilde

Master's Theses

Exposure to adverse experiences during childhood place adolescents at a disproportionately high risk of developing physical and mental health problems later in life (Anthony et al., 2019; Basto-Pereira et al., 2016; Brown & Shillington, 2016; Felitti et al., 1998). Further, at-risk adolescents, conceptualized as children and adolescents who lack resources for upward mobility, are more likely to be exposed to adverse experiences and thus are at greater risk for these negative outcomes when compared to adolescents who are not considered at-risk (Fernandes-Alcantara, 2018). To obtain better specificity of what outcomes adverse childhood experiences (ACEs) predict in a sample of vulnerable …

Quantifying Pain: A Ratio Of Cortisol, Substance P, And Pituitary Adenylate Cyclase-Activating Polypeptide As Biomarkers For Pain In Animal Cruelty And Neglect, Danielle Sherer

Master's Theses

Understanding the relationship between cortisol, Substance P, and PACAP during experienced pain and recovery, as well as the contrast between expression levels and serum levels, will provide an objective measure of pain and suffering to aid in the prosecution of animal cruelty and neglect cases.

There is no consensus at this time as to a recognized biomarker for pain experienced by an animal. Cortisol, Substance P, and Pituitary Adenylate Cyclase-Activating Peptide (PACAP) have been investigated separately in various animal and human studies with regard to stress, pain, and injury. Cortisol is a steroid hormone in the glucocorticoid class that has …

Fabrication Of Thin-Film Composite, Reverse-Osmosis Membranes With Polyethylenimine Modifications For Enhancing Membrane Fouling Resistance, Stephanie N. Hamilton

Master's Theses

Increasing water reuse opportunities for communities has become increasingly important as access to clean water is becoming more scarce. Reverse Osmosis (RO) is an advanced treatment technology used in water recycling wastewater for potable reuse applications. RO is a promising technology; however, the membranes have limitations including their high energy demand and their susceptibility to membrane fouling. The main objective of this study was to develop a reproducible method for the fabrication of RO membranes with enhanced flux and reduced susceptibility to fouling. Literature contains numerous publications on fabrication of thin film composite (TFC) RO membranes with high performance. However, …

Bicycling To Level The Field: A Study Of Divvy In Chicago, Bushra Ghaniwala

Master's Theses

With the onset of COVID-19, norms across the world shifted, including the way people moved in major cities. In order to conduct a comparative analysis, understanding transportation habits before COVID-19 hit cities is important. In this paper, I have focused on Divvy bikes in the city of Chicago, which are touted as a means to achieving first- and last-mile transit especially in underserved communities. I am interested in initiating the line of inquiring into who Divvy bikes served during a time when there was major fear around high transmission of COVID-19 on trains and buses due to the close proximity. …

Exploring The Role Of Lactobacillus Jensenii And Lactobacillus Mulieris In The Urogenital Tract, Adriana Daniela Ene

Master's Theses

Lactobacillus is a predominant species of the urogenital tract and it has been found in females with and without lower urinary tract symptoms. The Lactobacillus genus is thought to be beneficial to the host due to its capability to produce hydrogen peroxide, secondary metabolites, and lactic acid. L. jensenii is an organism frequently isolated from the urogenital tract. In March 2020, a new sister taxon of L. jensenii was described, L. mulieris. Shortly thereafter we produced a genomic analysis of all publicly available genomes (n = 43) which reclassified some L. jensenii as L. mulieris. This motivated the in-depth study …

Polyomavirus Jcpyv And Its Role In The Urinary Tract, Rita Lauren Mormando

Master's Theses

Polyomaviruses are the smallest closed-circular supercoiled double-stranded viruses found in the human microbiota. The polyomavirus JC (JCPyV) is most commonly found within the urinary tract, and prior studies estimate that 20-80% of older adults carry JCPyV. In very rare cases, JCPyV leaves the kidneys, causing progressive multifocal leukoencephalopathy. However, the role of JCPyV within the urinary tract remains an open question. In a prior study conducted by our group, the bladder microbiota of females with and without overactive bladder symptoms (OAB) were sequenced. Interestingly, JCPyV was only detected in females with OAB; none of the control (“asymptomatic”) microbiota contained JCPyV. …

A Comparative Study Of The Impact Of Regimes In Latin America’S Education Systems: The Cases Of Mercosur, Alba-Tcp, And Pa, Victoria Desimoni

Master's Theses

This thesis presents a comparative study of the regional education policies and programs in three Latin American (LA) regional entities (hereafter ‘regimes’ and ‘regionalisms’): The Southern Common Market (MERCOSUR), the Bolivarian Alliance for the Peoples of Our America – People’s Trade Treaty (ALBA-TCP), and Pacific Alliance (PA). Each of these represents different regionalisms coexisting in LA (hegemonic, post-hegemonic, and counter-hegemonic regionalisms), which makes them ideal for comparative analysis. This project aims to compare these very diverse regimes to interrogate the similarities and dissimilarities, as well as discover who (the regional or the global) is shaping education systems in this area …

Connecting School Climate And Trust: A Content Analysis Of Elements Of Trust In Student And Staff School Climate Surveys, Katherine Thyen

Master's Theses

This study aims to make a concrete connection between trust in schools and school climate. Research indicates that both trust and school climate can positively impact school experiences and performance for teachers and students, but no formal connection has been made between these two elements of schools. In order to answer this study’s research questions of “What differences in frequency and context of trust dimensions exist between student surveys and teacher surveys?” and “How are survey items related to trust dispersed across school climate domains?”, a directed qualitative content analysis was performed. School climate surveys administered to students and teachers …

Cataloging And Engineering Temperate Coliphages Of The Human Urinary Microbiome, Elias Crum

Master's Theses

In the US, around 60% of females will be diagnosed with a Urinary Tract Infection (UTI) in their lifetime, and Escherichia coli is the most implicated etiological agent in UTIs. Despite its frequent association with lower urinary tract symptoms, recent studies have found that the urinary microbiome (UMB), the viral, bacterial, and fungal resident members of the urinary tract, of healthy females can also consist of E. coli. While most research has focused on the bacterial constituents of the UMB, bacteriophages, viruses that infect bacteria, are far more abundant. Bacteriophages (phages) of other human microbiomes have been shown to play …

Constructing Planetary Citizens Through Ecopedagogy In U.S. Social Studies Standards, Madeline Anne Rainey

Master's Theses

The world is in the age of the Anthropocene, where humans are impacting the environment to disastrous effects. The capitalist economy, promoting neoliberal policies of mass consumption, has exacerbated the world's environmental deterioration and social inequity. The rights and responsibilities people hold have been rapidly changing with the fourth industrial revolution. Globalization and Information and Communications Technology (ICT) have further expanded notions of citizenship. While there have been numerous attempts to bring the environment into schools, it has not emphasized what this crisis deserves. Ecopedagogy, as a critical theory, explicitly examines the interplay between environmental and social problems and challenges …

Institutionalism, Peer Culture, And Cultural Reproduction In Active Shooter Drills, Lillian Wynne Platten

Master's Theses

Columbine, Sandy Hook, Parkland: these are words that represent moments in history where schools should have become unprecedented sites of tragedy and isolated events. Except Columbine occurred in 1999, Sandy Hook in 2012, and Parkland in 2016, making them almost commonplace alongside hundreds of other mass shootings in the US. In place of gun regulation, schools are mandated to conduct active shooter drills, which mimic actual shootings through simulated events including the use of rubber bullets and masked actors to produce visceral reactions. Research has shown that these drills have produced trauma and desensitization among teachers, administrators, and counselors; but …

Interplay Between Human Microbiota And Celiac Disease, John James Colgan

Master's Theses

Celiac disease is an autoimmune disorder of the small intestine in which gluten, an energy-storage protein in wheat and other cereals, elicits an immune response leading to villous atrophy. Despite a strong genetic component, the disease arises sporadically over the lifetime leading us to hypothesize the microbiome might be a trigger. Here, we re-examined 16S data from 3 prior studies examining celiac disease and the microbiome with newer computational tools: the dada2 and PICRUSt 2 pipelines. Our results both confirmed findings of previous studies and generated new data regarding the celiac microbiome of India and Mexico. The datasets were also …

Integrating Current Analyses Of The Breast Cancer Microbiome, Sidra Sohail

Master's Theses

Breast cancer is the leading cause of cancer death for women in the US. Many cancertypes have significant associations with their resident microbial communities - emerging evidence suggests that breast cancers also interact with the local tissue-associated microbiota. Studies have examined the relationship between breast cancer and its microbiome, however, the studies varied in their approaches used to evaluate these relationships. Microbiome research advances rapidly and analysis pipelines and databases are updated frequently. This dynamic environment makes inter-study comparisons and superficial evaluations challenging as no two studies are using the same standards for evaluation. Researchers have observed the microbiota of …

Taking It Too Far? Examining Derogation In Sexism Confrontations, Bayleigh Smith

Master's Theses

Sexism continues to be prevalent within today’s society (Bates, 2012; Crandall et al., 2018; World Health Organization, 2021), creating the need for methods to respond to such bias. Confrontation is one method that allows targets of sexism to stand up for themselves (Haslett & Lipman, 1997; Hyers, 2007; Kaiser & Miller, 2004), but often comes with social costs (e.g., being disliked, Czopp & Monteith, 2003; Dodd et al., 2001; Gulker et al., 2013; Kaiser & Miller, 2001). However, researchers have not dissected the factors that affect the social costs associated with confrontation (i.e., being labeled as a “sexist”, humor, or …

To Be Fair: Colorism And Online Dating Among Young South Asians, Kajal S. Patel

Master's Theses

Online dating is rooted in first impressions through images. Because of this, users of these apps tend to alter their profile pictures to fit a certain criteria that they believe will attract more matches. For people of color, this benchmark is based upon fair skin and European facial features. This has led me to ask, how is colorism reinforced in online dating apps for Indian Americans, and more specifically though, how are the users of these apps portraying themselves in their own profiles as it relates to colorism? Due to various factors Indians with darker skin tend to feel pressure …

Removing Soluble Phosphorus From Tertiary Municipal Wastewater Using Phosphorus- Deprived, Filamentous Microalgae, Aloysia Ahern

Master's Theses

Harmful algal blooms (HABs) can be detrimental to ecosystems, human health, and economies. The low levels of phosphorus remaining in the effluent of municipal wastewater treatment plants can contribute to HAB formation. To achieve more complete phosphorus removal, an effluent treatment method has been proposed that uses phosphorus-deprived, filamentous microalgae to quickly assimilate soluble phosphorus to low concentrations. This study investigated two parameters that influence the feasibility of such a system: (1) the biomass growth productivity of algal cultures during the phosphorus deprivation period and (2) the correlation between the duration of this period and the phosphorus uptake rate by …

An Integrated Approach For Controlling Verticillium Wilt Of Strawberry, Jack T. Koster

Master's Theses

Strawberry (Fragaria x ananassa, Duch.) is an important crop in California, with more than 35,000 acres planted in 2018 resulting in a farm gate value of $3.1 billion. In 2020, California strawberry production accounted for more than 85% of national strawberry production and faces serious threats to production due to various soil-borne diseases. One such disease, Verticillium wilt, is caused by the fungal pathogen Verticillium dahliae and is commonly found in temperate zones around the world where strawberries are grown. Due to the phase-out of efficacious fumigants like methyl bromide, alternative disease management methods have become necessary to …

Determination Of Fungicide Resistance In Botrytis Cinerea On Wine Grapes In California's Central Coast Region, Evelyn Alvarez-Mendoza

Master's Theses

Botrytis bunch rot, caused by Botrytis cinerea, is a fungal disease that primarily affects the fruit of wine grapes. Infection of fruit consequently results in reduced yields and wine quality. These factors lead to significant economic losses for growers which prompts the implementation of management practices to control the disease. One objective of this study was to evaluate the level of resistance that populations of B. cinerea in the Central Coast region showed to various chemicals. A fungicide assay was conducted to determine resistant phenotypes to six fungicide active ingredients (pyrimethanil, iprodione, fenhexamid, fludioxonil, trifloxystrobin, boscalid). Thirty-five (2020) and …
