Comunidades Y Vacunas: Findings On Vaccine Hesitancy In Latine Families With Autistic Children, Danica Leticia Limon-Mialkowski

Theses and Dissertations

Parent vaccine hesitancy (VH) and subsequent vaccine refusal for children has escalated in the U.S. over the past several years and is more common among parents with an autistic child compared to the general population (Zerbo et al., 2018). This is an important issue to address given that VH has led to a resurgence of vaccine-preventable diseases (DeStefano & Shimabukuro, 2019; Geoghegan, et al., 2020). Research shows that VH is affected by parent cultural background (Fombonne et al., 2020) and that minoritized groups are more likely to experience VH (48.1% in parents of color [POC] groups versus 22.9% in White …

A Machine Learning Approach To Quantitative X-Ray Diffraction Analysis, Spencer Snow Chandler

Theses and Dissertations

X-ray Powder Diffraction (XRPD) is a powerful method in material sciences that gives insights into the atomical and crystallographic structure of a material, revealing information into the material's properties and suitability for industrial and scientific application. In geology, XRPD analysis is frequently leveraged to identify and quantify the present mineral phases in an unknown mixture. Despite it's widespread use, interpreting XRPD patterns requires highly-specialized knowledge, making the analysis largely dependent upon the background experience of the analyst. To assist experts, computational methods have been developed over the years. Some of these techniques involve fitting diffraction patterns using pseudo-Voigt functions, which …

Picture This: An Event Designed To Increase Awareness Of And Empathy For Individuals Who Experience Scrupulosity, Savannah M. Travis

Undergraduate Honors Theses

Scrupulosity, also known as religious OCD, is often misunderstood and under-recognized by those who have experienced it. This research adopts an interdisciplinary approach, integrating experience design theories and frameworks with research on scrupulosity, to develop an event that aims to increase awareness and empathy among attendees for individuals who experience scrupulosity. The experience design frameworks applied include the design thinking process, the self-determination theory, and the experience-type framework. Current research suggests that there is a need for further research on the case studies and qualitative phenotypes of individuals who have experienced scrupulosity, which this study aims to address.

Approximating Transport Maps Using Minibatch Optimal Transport Plans, Dawson Collins

Theses and Dissertations

Optimal Transport theory (OT) has gained much attention in the past decades due to its rich mathematical content and striking connections to other areas of math. It has also naturally found a place in data science as a way to compare and transform probability measures. Unfortunately, there remain significant computational burdens that restrict its effectiveness in large-scale data regimes. In this thesis, we consider Minibatch Optimal Transport (MiniOT), which breaks up the task of computing the optimal transport plan between datasets into several smaller tasks of computing the optimal transport plan between minibatches of the datasets. After obtaining the minibatch …

Investigating Molecular Mechanisms Of Meiosis And Mitosis In Cryptosporidium Parvum, Abigail Kimball

Arts & Sciences Graduate Student Theses and Dissertations

The apicomplexan parasite Cryptosporidium parvum (Cp) is a major global contributor to infectious diarrhea in children and poses a serious threat to immunocompromised adults. This dissertation investigates Cp's unique life cycle, which alternates between sexual and asexual reproduction to achieve three critical objectives: producing oocysts capable of transmission, enhancing genetic variation through recombination, and generating sufficient progeny for survival. Sexual reproduction is essential for forming infectious oocysts that facilitate disease transmission. Yet, the process of meiosis in Cp has been historically understudied due to limitations of traditional in vitro culture methods. The newly developed air-liquid interface (ALI) culture system supports …

Exploring The Effect Of Led-To-Photodetector Spacing On Subcutaneous Photoplethysmography For Continuous Blood Pressure Measurement, Dario Cabal, Brian Nguyen, David B. Green, Kevin Kilgore, Varun Thakkar, Michael J. Fu, Steve J. Majerus

Student Scholarship

Photoplethysmography (PPG) is widely used to measure heart rate, blood oxygenation, and more recently, blood pressure. Implanted PPG systems offer the possibility to measure similar real-time measures of cardiovascular health, however, the detection method may vary due to a lack of capillary vessels for PPG sensors to observe in muscle tissue. To improve volumetric blood detection in large muscles, without relying on the capillary density of skin, a flexible PPG sensor was developed. The sensor included multiple spacing of illuminating infrared (IR) light emitting diodes (LEDs) and a single IR photodetector. This arrangement was expected to enable detection of blood …

The Role Of The Cytosolic Chaperonin Cct In The Folding And Assembly Of G Protein Complexes, Mikaila I. Sass

Theses and Dissertations

All organisms depend on cellular signaling pathways to dictate cell growth, responses to stimuli, and all other cellular functions necessary to maintain health and survival. Many of these signals rely on G protein coupled receptors (GPCRs) and their associated heterotrimeric G proteins for signal detection and transduction. To perform this function, the three subunits of the G protein must be assembled after synthesis on the ribosome. This process requires additional proteins called molecular chaperones to assist in folding of the subunits and assembly into the G protein heterotrimer. Among these chaperones, the cytosolic chaperonin CCT plays an essential role in …

A New Approach To Stability Of Delay Differential Equations With Time-Varying Delays Via Isospectral Reduction, Quinlan Leishman

Theses and Dissertations

Understanding how time delays impact the stability of a delay differential equation is important for modeling many natural and technological systems that experience time delays. Here we introduce a new stability criterion for delay-independent stability of these equations, called intrinsic stability, showing global exponential stability for a large class of nonautonomous nonlinear systems. Our approach is able to incorporate bounded time-varying delays, including those with certain types of discontinuities. The approach we take to prove this result is novel, associating the delay differential equation with a sequence of finite-dimensional matrices of increasing size and using the graph-theoretic technique of isospectral …

Math 112 At Byu: Student Averages On Various Exam Questions, Makayla Mcleod

Theses and Dissertations

In Math 112 at BYU, exams play a crucial role in evaluating students' understanding of the course content. Traditionally, these exams are a combination of multiple-choice and free-response questions, with the latter serving as a means to assess a student's thought process while solving problems. Will students perform as well on a multiple-choice exam? Or will students' averages be higher on free-response exams? In this thesis, we test 7 hypotheses related to these questions to provide more insight into the answer. We examine other factors that may affect students' averages, including various Calculus 1 topics, modes of questioning, and difficulty …

The Overlooked Impact Of Background Diet And Adherence In Nutrition Trials, Javier I Ottaviani, Hagen Schroeter, Dennis M Bier, John W Erdman, Howard D Sesso, Joann E Manson, Gunter G C Kuhnle

Children’s Nutrition Research Center Staff Publications

Randomised controlled trials in nutrition (RCTN) face unique challenges, including the considerable influence of the background diet and the challenge of assuring intervention adherence by participants. The impact of these factors on the outcome of RCTNs has been difficult to quantify, but nutritional biomarkers represent a valuable tool to address these challenges. Using flavanols as a model dietary intervention and a set of recently validated flavanol biomarkers, we here investigated the impact of background diet and adherence on the outcomes of a subcohort of the COcoa Supplement and Multivitamin Outcomes Study (COSMOS, NCT 02422745). We found that 20% of participants …

Seeking Structure In Complex Systems: From Feature Analysis To Space-Time Causal Discovery With Earth Science Applications, Jeffrey J. Nichol

Appreciating Dissonance: Using Open Appreciative Inquiry As A Tool To Generate Cultural Change, Charles Dorr, Sheena Asthana, Julian Elston, Felix Gradinger, Daniel Preece, David Schwartz, Gemma Scott, Gary Wallace, Ruth Harrell

More Faculty of Health Research

Appreciative inquiry has become increasingly popular as a method for facilitating organisational or systemic change through focusing on the positive aspects and ‘life giving properties of a system’ as opposed to traditional ‘deficit-based’ approaches. However, there has been criticism that this process could invalidate negative experiences of organisations and/or systems. This is particularly problematic if an existing system is seen by its users as providing little value or if there is potential dissonance regarding system value among key stakeholders. Using two case studies of open appreciative inquiry by Plymouth City Council staff, this article outlines how the use of a …

Conceptualizing The Research Cycle For The Field Of Materials Science And Engineering, Jennifer L.W. Carter

Faculty Scholarship

Abstract: Early-career materials researchers often receive guidance from their individual advisors on best practices for conducting research, but the materials science community lacks an explicit model of the research process. As a result, the lived experience of an individual researcher can be quite different from their peers since they may be exposed to a different unique set of implicit research steps. In this article, we translate an existing research heuristic from other fields and make explicit the steps, methodologies, and strategies materials science engineering researchers utilize to advance our collective materials science knowledge. This newly proposed research cycle can improve …

Generalising information from ourselves to others, and others to ourselves allows for both a dependable source of navigation and adaptability in interpersonal exchange. Disturbances to social development in sensitive periods can cause enduring and distressing damage to lasting healthy relationships. However, identifying the mechanisms of healthy exchange has been difficult. We introduce a theory of self-other generalisation tested with data from a three-phase social value orientation task - the Intentions Game. We involved humans with (

Manual For Independence: How Democratic-Republicans Used The Memory Of The Revolution To Start The War Of 1812, Chloe Pellegrin

LSU Master's Theses

In its earliest form, the memory of the American Revolution was far from pure, riddled with partisan jabs and purposeful currents of present events. This, however, has received little attention even with the rise of memory studies within professional history. Scholars have addressed the popular memory of a variety of other pivotal moments from the Civil War to both World Wars. Revolutionary memory has been studied within the contexts of later eras, but almost never in the era immediately following the end of the war. Other scholars such as Alfred Young, Margot Minardy, and Michael McDonnell have all done work …
