Evaluating Equitable Access To Nutrition In Utah, Emma Stucki Dec 2022

Evaluating Equitable Access To Nutrition In Utah, Emma Stucki

Theses and Dissertations

One of the more recent topics in transportation policy making and project prioritization in DOT's across the United States is how to improve quality of life. This quality of life focus is an intersection of public health and transportation and has many different branches including traffic safety, pollution, active transportation, equity, and accessibility to resources. The topic among these that seems to receive the least attention is equitable access to resources. However, with the proven impact that equitable access to resources has on physical and emotional well-being, as well as economic opportunity it is important to ensure that all populations, …

Medical And Socioeconomic Predictors Of Psychosocial Functioning In Pediatric Hydrocephalus, Vanessa Wall Dec 2022

Medical And Socioeconomic Predictors Of Psychosocial Functioning In Pediatric Hydrocephalus, Vanessa Wall

Theses and Dissertations

Hydrocephalus can impact all areas of health, including physical, cognitive, and psychosocial functioning. Etiology can be a major factor in health outcomes, but prior research on psychosocial functioning in hydrocephalus has been with limited etiologies. This study examined psychosocial functioning using the Behavioral Assessment System for Children, Third Edition (BASC-3) and the Hydrocephalus Outcome Questionnaire (HOQ) in children aged 5-17 years old. BASC-3 and HOQ parent report scores were compared between hydrocephalus etiologies. Medical factors (number of CSF diversion procedures, history of seizures, and years with hydrocephalus) and SES factors (family income, parent education, and parent occupational status) were examined …

The Role Of Chitinase A In Mastitis-Associated Escherichia Coli Pathogenesis, Weston D. Hutchison Dec 2022

The Role Of Chitinase A In Mastitis-Associated Escherichia Coli Pathogenesis, Weston D. Hutchison

Theses and Dissertations

Bovine mastitis is a common disease among dairy cattle characterized by the inflammation of the udders and loss of milk production. Mastitis-associated Escherichia coli (MAEC) are frequent causes of the disease, but the features that distinguish them from other E. coli strains remain enigmatic. MAEC infections can range from sub-clinical to severe, acute cases that can be fatal. Historically, the severity of mastitis has been attributed to host factors but more recently, a few bacterial genes have been shown to contribute to virulence in mastitis infections. In a large-scale genomic analysis of >100 MAEC isolates the gene for Chitinase A …

The Flex Representation Method: Versatile Modeling For Isogeometric Analysis, Christopher David Whetten Dec 2022

The Flex Representation Method: Versatile Modeling For Isogeometric Analysis, Christopher David Whetten

Theses and Dissertations

The Flex Representation Method (FRM) leverages unique computational advantages of splines to address limitations in the process of building CAE simulation models from CAD geometric models. Central to the approach is the envelope CAD domain that encapsulates a CAD model. An envelope CAD domain can be of arbitrary topological and geometric complexity. Envelope domains are constructed from spline representations, like U-splines, that are analysis-suitable. The envelope CAD domain can be used to approximate none, some, or all of the features in a CAD model. This yields additional simulation modeling options that simplify the model-building process while leveraging the properties of …

Madwoman On The Screen: Streaming Forms Of Feminine Power, Kassandra I. Schreiber Dec 2022

Madwoman On The Screen: Streaming Forms Of Feminine Power, Kassandra I. Schreiber

Theses and Dissertations

This paper explores how the formal aspects of streaming platforms create a female inheritance that helps foster multiple representations of femininity and womanhood which empowers women. Building off of Sandra Gilbert and Susan Gubar's Madwoman in the Attic, the paper argues that because streaming platforms produce original content, are a space for multiplicity and interconnection, and act as a type of archive, they can build a female inheritance. The combination of these attributes offer a widespread emergence of multiple stories that valorize women and what is socially coded as feminine, creating a creative network that improves the representation of women …

Complete Equitable Decompositions, Joseph Paul Drapeau Dec 2022

Complete Equitable Decompositions, Joseph Paul Drapeau

Theses and Dissertations

A well-known result in spectral graph theory states that if a graph has an equitable partition then the eigenvalues of the associated divisor graph are a subset of the graph's eigenvalues. A natural question question is whether it is possible to recover the remaining eigenvalues of the graph. Here we show that if a graph has a Hermitian adjacency matrix then the spectrum of the graph can be decomposed into a collection of smaller graphs whose eigenvalues are collectively the remaining eigenvalues of the graph. This we refer to as a complete equitable decomposition of the graph.

Psychological Distress Mediates The Relationship Between Health And Satisfaction With Daily Marital Interactions: A Daily Diary Assessment, Stephanie L. Richardson Dec 2022

Psychological Distress Mediates The Relationship Between Health And Satisfaction With Daily Marital Interactions: A Daily Diary Assessment, Stephanie L. Richardson

Theses and Dissertations

Literature has often connected the variables of physical health, mental health, and romantic relationship satisfaction or quality. However, there has yet been any evidence of a mediating relationship. The purpose of this study is to test for mediation of satisfaction with daily marital interactions on physical symptoms through psychological distress. The data is from the Life and Family Legacies Daily Experiences Study and includes 191 older couples over the course of 14 days. Multilevel dyadic models were estimated for both the same-day data as well as lagged data. Indirect effects between the variables were significant, but not for the lagged …

Autonomic Responses During Animated Avatar Video Modeling Instruction Of Social Emotional Learning To Students With Adhd: A Mixed Methods Study, Jesse D. Rhodes Dec 2022

Autonomic Responses During Animated Avatar Video Modeling Instruction Of Social Emotional Learning To Students With Adhd: A Mixed Methods Study, Jesse D. Rhodes

Theses and Dissertations

For those with attention deficit hyperactivity disorder (ADHD), social interactions involving high levels of face-to-face interaction can raise stress levels and emotional dysregulation. Using animated avatar video models may mitigate potential emotional dysregulation while learning social skills in these populations. This study examined autonomic data of adolescents aged 7-13 diagnosed with attention deficit hyperactivity disorder (ADHD), n=5 during avatar animated video modeling (AAVM) of social and emotional skills. This was a replication study with the addition of biofeedback data collection and a change of population. Participants were given three Nearpod training modules with AAVM and multiple-choice quizzes on self-awareness, social …

Developing A Quantitative Understanding Of U-Substitution In First-Semester Calculus, Leilani Camille Heaton Fonbuena Dec 2022

Developing A Quantitative Understanding Of U-Substitution In First-Semester Calculus, Leilani Camille Heaton Fonbuena

Theses and Dissertations

In much of calculus teaching there is an overemphasis on procedures and manipulation of symbols and insufficient emphasis on conceptual understanding of calculus topics. As such students to struggle to understand and use calculus ideas in applied settings. Research shows that learning calculus topics from a quantitative reasoning-perspective results in more powerful and flexible conceptions of calculus topics like integration. However, topics beyond introducing integrals and the Fundamental Theorem of Calculus, like u-substitution, have yet to be explored from a quantity-based perspective. In this study, I conducted a set of two clinical interviews where we discussed quantitative meanings of integrals, …

Teacher Perceptions Of Grades And Grading In A Pandemic, Michael V. Anderson Dec 2022

Teacher Perceptions Of Grades And Grading In A Pandemic, Michael V. Anderson

Theses and Dissertations

A grade serves as the primary means of reporting feedback to teachers, students, and parents about the student's level of learning (Heflebower et al., 2014). Many schools have attempted to have teachers adopt standards-based grading, yet school leaders do not know teachers' perceptions about grades and grading. This quantitative study examines the perceptions of 1271 secondary teachers in one school district regarding grades and grading and how they may have changed as a result of the COVID-19 pandemic. Data collected from a survey reveals how changes in teacher perceptions about grades and grading may yield an opportunity for further standards-based …

A Machine Learning Approach For Identification Of Low-Head Dams, Salvador Augusto Vinay Mollinedo Dec 2022

A Machine Learning Approach For Identification Of Low-Head Dams, Salvador Augusto Vinay Mollinedo

Theses and Dissertations

Identifying Low-head dams (LHD) and creating an inventory become a priority as fatalities continue to occur at these structures. Because obstruction inventories do not specifically identify LHDs, and they are not assigned a hazard classification, there is not an official inventory of LHD. However, there is a multi-agency taskforce that is creating an inventory of LHD. All efforts have been performed by manually identifying LHD on Google Earth Pro (GE Pro). The purpose of this paper is to assess whether a machine learning approach can accelerate the national inventory. We used a machine learning approach to implement a high-resolution remote …

Parental Warmth And Disciplinary Strategies In Two-Parent-Adoptive And Biological Families, Jordan Coburn Dec 2022

Parental Warmth And Disciplinary Strategies In Two-Parent-Adoptive And Biological Families, Jordan Coburn

Theses and Dissertations

Adopted children enter families with parents who on average are older, have higher income, and have more education than other family structures. Because adopted children are moving into families with more resources, research suggests that they would do just as well as, and perhaps even better than, children in biological two-parent households. However, this is not always the case. Understanding how different variables could offset any negative results of adoption is a puzzle that researchers are continually exploring. Previous research has investigated differences in investments from adoptive and biological parents through multiple theoretical lenses. I seek to add to current …

Does Predation Environment Affect Repeated Responses To Predation Cuesâ In The Fishâ Brachyrhaphis Rhabdophora?, Madeleine S. Nate Dec 2022

Does Predation Environment Affect Repeated Responses To Predation Cuesâ In The Fishâ Brachyrhaphis Rhabdophora?, Madeleine S. Nate

Theses and Dissertations

Individual organisms face trade-offs when dealing with predation—more time spent avoiding predators often results in less time allocated to energy acquisition and reproductive-related activities. Individuals that optimize this trade-off and respond appropriately to current risk levels in their environment should be at an advantage. What is less clear is whether this tradeoff changes when individuals are repeatedly exposed to a predation threat. There may be advantages to responding consistently to every signal of threat, but it might also be advantageous to modulate individual behavior. Moreover, it is unclear how evolutionary history of a population might affect such individual responses. Our …

High School Dropouts, Higher Education Dreams, And Achievement: A Six-Year Study Of A High-Stakes Test In Brazil, Eveline Miranda Dec 2022

High School Dropouts, Higher Education Dreams, And Achievement: A Six-Year Study Of A High-Stakes Test In Brazil, Eveline Miranda

Theses and Dissertations

Rumberger (2020) observed that "dropping out of school has economic and social consequences both for dropouts themselves and for the country as a whole" (p. 151). Every year, many Brazilians drop out of school due to work, early pregnancies, marriage, drug consumption, crime, etc. Dropping out of school can occur due to learning challenges, poor attendance, discipline problems, or a lack of access to high school institutions. Dropouts can experience depression and anxiety and are more likely to attempt suicide. The present dissertation includes two different papers about dropouts. The first paper uses fixed effect regression to show the main …

Structural Reasoning With Rational Expressions, Dana Steinhorst Dec 2022

Structural Reasoning With Rational Expressions, Dana Steinhorst

Theses and Dissertations

Many students struggle to make sense of algebraic expressions in math. This lack of understanding results in students making symbolic manipulation errors, hindering their procedural fluency. Researchers believe these errors are linked to students' lack of structural reasoning. While research has shown that students rarely engage in expert structural reasoning, little is known about how students actually reason structurally. In this study, I interviewed six high school calculus students to study the way they identified, matched, and evaluated structures as they solved problems involving rational expressions and equations. I analyzed the participant interviews and outlined the matching process they used …

Teaching Social-Emotional Learning To Children With Autism Using Animated Avatar Video Modeling, Emelie Davis Dec 2022

Teaching Social-Emotional Learning To Children With Autism Using Animated Avatar Video Modeling, Emelie Davis

Theses and Dissertations

People with a diagnosis of autism spectrum disorder (ASD) often have difficulties understanding or applying skills related to Social-Emotional Learning (SEL). An individual having a better understanding of SEL concepts is generally associated with more fulfilling connections with others and increased satisfaction in life. Since people with ASD tend to have greater success with learning in structured environments, we created a module to teach these skills using Nearpod. These modules were created with videos of a person embodying a cartoon dog face using Animoji for two reasons; because the animation was meant to appeal to children, and the creation was …

Determination Of A Catalytic Mechanism By Time Resolved Fourier Transform Infrared Spectroscopy And Time Domain Analysis Of Data From Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, Jacob T. Davis Dec 2022

Determination Of A Catalytic Mechanism By Time Resolved Fourier Transform Infrared Spectroscopy And Time Domain Analysis Of Data From Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, Jacob T. Davis

Theses and Dissertations

Heterobimetallic catalysts offer large potential for efficient and selective catalysis of a wide range of reactions. Better understanding of these catalytic mechanisms could yield further improvement in their catalytic abilities. Cp(CO)2Fe-Cu(IPr) (IPr = N,N-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) is a catalyst that has been reported to catalyze arene borylation. The catalytic mechanism of this catalyst that had been previously proposed had the initial step being a metal-metal cleavage. However, computational modeling suggested an alternate mechanism that could be more energetically favorable. Rather than a metal-metal cleavage as the initial step, we proposed a photoactivated carbonyl dissociation. To support this proposition, we performed time resolved …

Zeros Of A Family Of Complex-Valued Harmonic Rational Functions, Alexander Lee Dec 2022

Zeros Of A Family Of Complex-Valued Harmonic Rational Functions, Alexander Lee

Theses and Dissertations

The Fundamental Theorem of Algebra is a useful tool in determining the number of zeros of complex-valued polynomials and rational functions. It does not, however, apply to complex-valued harmonic polynomials and rational functions generally. In this thesis, we determine behaviors of the family of complex-valued harmonic functions $f_{c}(z) = z^{n} + \frac{c}{\overline{z}^{k}} - 1$ that defy intuition for analytic polynomials. We first determine the sum of the orders of zeros by using the harmonic analogue of Rouch\'e's Theorem. We then determine useful geometry of the critical curve and its image in order to count winding numbers by applying the harmonic …

Single-Shot, Ultrafast, Multi-Frame X-Ray Imaging Of Defect-Bearing Ablator Materials In Extreme Conditions, Daniel S. Hodge Dec 2022

Single-Shot, Ultrafast, Multi-Frame X-Ray Imaging Of Defect-Bearing Ablator Materials In Extreme Conditions, Daniel S. Hodge

Theses and Dissertations

Characterization of the dynamic behavior of defect-bearing ablator materials subjected to extreme conditions is essential in advancing fusion energy as an reliable and abundant energy source. By understanding how materials evolve spatially and temporally we can minimize hydrodynamic instabilities, which are major contributing factors to energy yield degradation in inertial confinement fusion (ICF) experiments. In this thesis we demonstrate the capabilities of an ultrafast x-ray imaging (UXI) detector, the Icarus V2, where we capture multiple frames of single void-bearing sample compressed by a high-intensity laser shockwave. Using the Matter in Extreme Conditions (MEC) instrument at the Linac Coherent Light Source …

Creating An Instrument To Explore The Self-Efficacy Of Writing Instructors To Teach Apprehensive Writers, Kathleen Marie Romrell Dec 2022

Creating An Instrument To Explore The Self-Efficacy Of Writing Instructors To Teach Apprehensive Writers, Kathleen Marie Romrell

Theses and Dissertations

Writing apprehension is a writing difficulty that can impair the writing experiences of students. While researchers have proposed many interventions that teachers can implement to assist their students who struggle with writing apprehension, there has not been an instrument that is designed to measure teacher self-efficacy to help these same students. This study created such an instrument, entitled the Self-efficacy to Teach Apprehensive Writers Scale (STAWS), using Tschannen-Moran and Woolfolk Hoy’s (2001) Teacher Sense of Efficacy Scale and Daly and Miller’s (1975) Writing Apprehension Test as model instruments. The new instrument was designed to measure writing instructor self-efficacy to teach …

Delivering Explicit Math Instruction Through Point-Of-View Video Modeling To Elementary Students With Autism Spectrum Disorder, Patsy Mccray Gibbs Dec 2022

Delivering Explicit Math Instruction Through Point-Of-View Video Modeling To Elementary Students With Autism Spectrum Disorder, Patsy Mccray Gibbs

Theses and Dissertations

There is significant literature demonstrating the effectiveness of video modeling for teaching skills to students with disabilities. Still, much less is known about how video modeling, particularly point-of-view video modeling (POV-VM), might be applied to teach academic skills to children with an autism spectrum disorder. This multiple probe single-case design study used explicit instruction techniques to teach multiplication, division, and fraction skills to two elementary-aged students with an autism spectrum disorder. A visual analysis of the data showed that POV-VM using explicit techniques to deliver the videos is an effective intervention for autistic students This research study adds to the …

Decision-Based Learning As A Tool For Teaching Statistics In A Peruvian University, Gloria Mora Barba Dec 2022

Decision-Based Learning As A Tool For Teaching Statistics In A Peruvian University, Gloria Mora Barba

Theses and Dissertations

Many students find that learning statistics is difficult, especially novice learners first taking statistical classes. Instructors also struggle to teach statistics due to many challenges, such as students' misconceptions, lack of math skills, negative attitudes, and deficient instructional methods. A new pedagogical approach called Decision-Based Learning (DBL) has been developed to help instructors and students overcome these challenges. A group of Peruvian university professors in 2018 and 2019 were trained to use DBL. However, limited studies have explored DBL instructors' and students' experiences using DBL in Peru. The aim of this qualitative research study is to deeply understand the experiences …

Quantifying Shape Variation In An Antisymmetrical Trait In Xenophallus Umbratilis, Mary-Elise Johnson Nielsen Dec 2022

Quantifying Shape Variation In An Antisymmetrical Trait In Xenophallus Umbratilis, Mary-Elise Johnson Nielsen

Theses and Dissertations

Antisymmetry is a striking, yet puzzling form of biological asymmetry. The livebearing fish Xenophallus umbratilis exhibits antisymmetry in the male intromittent organ and provides a system that is well-suited for studying the nature of variation in antisymmetrical traits. Using geometric morphometrics, I test the hypothesis that because the gonopodium is critical to fitness there will not be significant differences in gonopodium shape between the two gonopodial morphs in this species. My results are consistent with this prediction, though I found that gonopodium shape did differ with gonopodium size.

Identity Work To Teach Mathematics For Social Justice, Navy B. Dixon Dec 2022

Identity Work To Teach Mathematics For Social Justice, Navy B. Dixon

Theses and Dissertations

In this thesis, mathematics educators are conceptualized as individuals with multiple, simultaneous figured worlds that inform their decisions while planning. The study explores how two mathematics educators negotiated and orchestrated their figured worlds to plan two mathematics lessons for social justice. The results highlight how numerous the figured worlds each participant surfaced through background interviews. Some of the figured worlds were elicited by the interview questions (i.e., Race, Family, Social Justice Teaching) but other figured worlds organically surfaced through the interviews (i.e., Sexuality, Community, Activism, Critical Information Consumption). A discursive analysis of a selection of these figured worlds revealed conceptualizations …

"This Is The Way": Gender Representation In Disney's The Mandalorian, Brooke Solorio Dec 2022

"This Is The Way": Gender Representation In Disney's The Mandalorian, Brooke Solorio

Theses and Dissertations

When Disney released The Mandalorian, it quickly became the top show on its highly popular streaming platform. As with all media wielding this level of exposure, it is important to closely examine its content for depictions of peoples including females. In accordance with Sandra Bem's gender schema theory, the implicit messaging in this series can influence the formation of people's mental shortcuts about what it means to be female. This study employs content analysis to illuminate the portrayal of physical and non-physical attributes of the women present in the two seasons existing at the time of this study. Results reveal …

Is Teaching Experience A Predictor For School Psychologists' Confidence And Competence In Behavior Intervention Plans?, Misty Dawn Lainé Coplan Dec 2022

Is Teaching Experience A Predictor For School Psychologists' Confidence And Competence In Behavior Intervention Plans?, Misty Dawn Lainé Coplan

Theses and Dissertations

The Individuals with Disabilities Education Improvement Act (IDEIA) introduced Behavior Intervention Plans (BIPs) into United States law in 1990, and the reauthorization of IDEIA occurred in 2004. Even though BIPs have been codified into law, school personnel struggle to meet BIP mandates due to poor implementation fidelity. Barriers for BIP implementation are varied, but there is little research regarding whether practitioner competence and confidence through teaching experience is a factor. School psychologists (N = 122) from eight states completed a self-evaluation survey using the tailored design method. Results from the survey compared responses from school psychologists with and without teaching …

Performance Criteria For Knee-Brace Timber Frames With Mortise And Tenon Joints, Zachary J. Halisky Dec 2022

Performance Criteria For Knee-Brace Timber Frames With Mortise And Tenon Joints, Zachary J. Halisky

Theses and Dissertations

Traditional mortise and tenon timber frames have been used in modern construction for a substantial period of time with acceptable performance against weather phenomena and other hazards. However, performance criteria for this style of timber framing are not well defined in current codes and standards. To determine performance criteria for free-standing timber frames with knee-braces, three tasks were undertaken: (1) Two timber frame specimens were tested under cyclic loads to determine hysteretic behavior, damage states, and to explore rehabilitation of a damaged member using self-tapping screws. Three damage states for were identified: peg shear, tenon tearout, and post or beam …

Mammals Of The Jesús María River Basin, Western Mexico: Alpha And Beta Diversity In An Area Of High Environmental Heterogeneity, Celia López-González, Diego F. García-Mendoza, Teresa Salas-H

Western North American Naturalist

The Jesús María River basin in the state of Nayarit, Mexico, is located at the intersection of Nearctic and Neotropical regions in the Sierra Madre Occidental (SMO) in western Mexico. Because of its biological importance, the basin is considered a terrestrial priority region (RTP-059) by CONABIO, the institution responsible for inventorying Mexican biodiversity. Several vegetation types occur in this relatively small area (cloud and tropical forests, conifer forests, subtropical scrub). However, the area has been undersampled because of its difficult access and topographic complexity. Based on our own collections, review of museum specimens, and literature records, we recorded 92 species …

Novel Patterns For Nucleosome Positioning: From In Vitro To In Vivo, David Andrew Bates Dec 2022

Novel Patterns For Nucleosome Positioning: From In Vitro To In Vivo, David Andrew Bates

Theses and Dissertations

The fundamental unit of chromatin is the nucleosome, which consists of a core of eight proteins wrapped by DNA. This core is composed of four pairs of histone proteins: H2A, H2B, H3, and H4. The DNA wraps around the protein core ~1.7 times, facilitating compaction of DNA length in the cell. Further, the location of nucleosomes makes genomic elements encoded in the DNA, such as promoters or enhancers, accessible or inaccessible to RNA polymerase and transcription factors. Thus, where nucleosomes are located (or positioned), can play a major role in transcription or other cellular processes. Additionally, histone proteins are frequently …
