Behavioral And Neural Correlates Of Sensory Processing And Anxiety In Autistic Children, Kelsey Lee Ustach Tindall Jun 2021

Behavioral And Neural Correlates Of Sensory Processing And Anxiety In Autistic Children, Kelsey Lee Ustach Tindall

Theses and Dissertations

Children diagnosed with Autism Spectrum Disorder (ASD) are known to experience higher levels of sensory processing differences as well as anxiety, compared to the neurotypical population (NT). Both theory and evidence suggest that there is an interrelationship between sensory processing, anxiety and fear, and prediction abilities in autism. However, much more remains to be discovered about their relationship and especially underlying neural mechanisms. Thus, the purpose of the current study was to examine the behavioral relationship between sensory processing, fear and anxiety, prediction, and related brain activity in autistic children. To this end, 30 autistic children (ages 6-11 years) and …

Taxonomy And Phylogenetics Of Island Damselflies (Odonata: Coenagrionidae: Vanuatubasis), Natalie Anne Saxton Jun 2021

Taxonomy And Phylogenetics Of Island Damselflies (Odonata: Coenagrionidae: Vanuatubasis), Natalie Anne Saxton

Theses and Dissertations

Odonata is an order of charismatic insects, commonly called dragonflies and damselflies, that provide a rewarding study system to answer questions such as those related to diversity and biogeography. Despite being relatively well-studied compared to other insect orders, odonates have suffered from inconsistencies and disagreements about proper morphological terminology that provide barriers to incoming workers. These disagreements have subsequently led to confusion and the incorrect application of terms. Here, we clarify the terminology and propose standard terminology for terminal appendages. This terminology is employed in a taxonomic revision of Vanuatubasis Ober & Staniczek, 2009. This endemic genus of damselfly found …

"The Problem Of Missing Data And The Conover Solution In State-Level Data", David Michael Simpson Jun 2021

"The Problem Of Missing Data And The Conover Solution In State-Level Data", David Michael Simpson

Theses and Dissertations

The Conover Solution is a nonparametric method used to analyze relative growth in students' achievement on state tests administered on two or more occasions. However, there has been very little research assessing the robustness of this method in the presence of missing data. Using vertically scaled and non-vertically scaled data from the math portion of a statewide assessment for grades 4-7, I compare results from listwise deletion and multiple imputation across the residual gain score model, the simple gain score model, and the HLM-NPAR model. In these approaches, I study differences by gender and race in two-level models and then …

Correlations Between Cognitive Pause Patterns And Listener Perceptions Of Communicative Effectiveness And Likeability For People With Aphasia, Heidi Raylene Mcconaghie Jun 2021

Correlations Between Cognitive Pause Patterns And Listener Perceptions Of Communicative Effectiveness And Likeability For People With Aphasia, Heidi Raylene Mcconaghie

Theses and Dissertations

A prevalent feature of typical spontaneous speech are speech pauses. Longer speech pauses, known as cognitive pauses, occur in typical speech and are indicative of higher-level cognitive processes. Atypical cognitive pauses, however, are prevalent in the speech of people with aphasia consequent to their communication disorder. Research has shown that these atypical pauses may contribute to negative listener perceptions. This study aimed to determine the influence of atypical speech pause on listener perceptions of communicative effectiveness and speaker likeability. Specifically, this study evaluated the relationship between listener ratings of communicative effectiveness and likeability and acoustic measures of between-utterance pause duration, …

The Influence Of Pause On Listeners' Perceptions In Speech Of People With Aphasia, Emily Wright Jun 2021

The Influence Of Pause On Listeners' Perceptions In Speech Of People With Aphasia, Emily Wright

Theses and Dissertations

The purpose of this study was to examine how varying pause lengths in speech of people with aphasia (PWA) influences listeners' perceptions. The study specifically assesses listeners' perceptions of communicative effectiveness and speaker likability. Speech samples from six people with nonfluent or fluent aphasia were obtained from a previous study conducted by Harmon (2018). The speech samples were modified to create four sets of stimuli, including the original recordings, normalized within utterance pauses, normalized between utterance pauses, and normalized for both within and between utterance pauses. Forty listeners rated each of the speech samples based on the perceived communicative effectiveness …

Behavior Of Unreinforced Lightweight Cellular Concrete Backfill For Reinforced Concrete Retaining Walls, Ryan Jeffrey Wilkinson Jun 2021

Behavior Of Unreinforced Lightweight Cellular Concrete Backfill For Reinforced Concrete Retaining Walls, Ryan Jeffrey Wilkinson

Theses and Dissertations

Lightweight cellular concrete (LCC) is a mixture of cement, water and foam, with a density less than 50 pcf. This material is being used increasingly often in a variety of construction applications due to its self-leveling, self-compacting, and self-consolidating properties. LCC may be used as a backfill or structural fill in areas where traditional granular backfill might normally be used. This material may be especially advantageous in areas where the underlying soil may not support the weight of a raised earth embankment. Testing on the behavior of LCC when used as backfill behind retaining walls is relatively limited. The effects …

Effective Temperature Control For Industrial Friction Stir Technologies, Arnold David Wright Jun 2021

Effective Temperature Control For Industrial Friction Stir Technologies, Arnold David Wright

Theses and Dissertations

Systematic investigation of the Friction Stir Welding (FSW) process shows that a fixed rotational velocity and feed rate may not yield uniform mechanical properties along the length of a weldment. Nevertheless, correlations between process parameters and post-weld material properties have successfully demonstrated that peak temperature and cooling rate drive post-weld properties. There have been many reported methodologies for controlling friction stir welding, with varying degrees of cost to implement and effectiveness. However, comparing data from uncontrolled FSW of AA 6111-T4 sheet with controlled FSW at temperatures ranging from 375 °C to 450 °C demonstrates that a simplified methodology of a …

“God’S Fair Land Of Ireland Did Not Hold Her Equal”: Disgust As An Anti-Eugenics Tool In James Joyce’S Ulysses, Lizzie Belnap Jun 2021

“God’S Fair Land Of Ireland Did Not Hold Her Equal”: Disgust As An Anti-Eugenics Tool In James Joyce’S Ulysses, Lizzie Belnap

Theses and Dissertations

While many modernist authors exhibited eugenicist tendencies which I While many modernist authors exhibited eugenicist tendencies which I will detail in this paper, Joyce wrote, implicitly and explicitly, against it. Joyce’s anti-eugenics aesthetic, expressed almost in passing by Stephen Dedalus in A Portrait of the Artist As a Young Man (1916), becomes entangled in questions of bodies and national identity in Ulysses. I intend to identify a series of moments in which disgust and bodily difference in Ulysses counter the eugenics trends in elitist modernism while simultaneously criticizing racism in Irish nationalism that, in some ways, drove the movement for …

The Role Of The Cytosolic Chaperonin Cct In Folding Β-Propeller Proteins, William Grant Ludlam Jun 2021

The Role Of The Cytosolic Chaperonin Cct In Folding Β-Propeller Proteins, William Grant Ludlam

Theses and Dissertations

Many Proteins require the aid of molecular chaperones to achieve a stable folding state and avoid misfolding pathologies. A major eukaryotic chaperone is the cytosolic chaperonin CCT. While CCT is known to fold a significant portion of all cytosolic proteins, there is no general model for the mechanism CCT uses to fold substrate proteins. One class of proteins that CCT is known to fold are β-propeller containing proteins. Here, we present structural and biochemical data on the processes that CCT uses to fold three distinct β-propeller proteins: the G-protein Beta 5 (Gβ5) subunit of the Gβ5-RGS complex, mLST8 of the …

Cationic Steroid Antimicrobials: Applications To Medical Device Coatings, Mechanism Of Pro-Osteogenic Properties, And Potential Synergy With Common Antifungals, Brian J. Hilton Jun 2021

Cationic Steroid Antimicrobials: Applications To Medical Device Coatings, Mechanism Of Pro-Osteogenic Properties, And Potential Synergy With Common Antifungals, Brian J. Hilton

Theses and Dissertations

Cationic steroid antimicrobials (CSAs or ceragenins) are a novel class of synthetic, cholic acid-based mimics of endogenous antimicrobial peptides. These small molecule compounds display broad bactericidal activity against gram-negative and gram-positive bacteria, potent ability against fungal pathogens, and cidal effects against drug resistant and multidrug resistant microbes. Implantable medical devices provide an abiotic surface upon which bacteria and fungi can accumulate--thereby leading to localized or systemic infection. We proposed that CSA antibiotics can be incorporated into medical device surface coatings which can be optimized for the active release or elution of the CSA compounds over time to prevent device-associated infections. …

Romantic Symbolism Re-Examined: The Ontic Fallacy, Ryan Mitchell Worth Jun 2021

Romantic Symbolism Re-Examined: The Ontic Fallacy, Ryan Mitchell Worth

Theses and Dissertations

Romantic symbolism is a poorly understood concept. It was first formulated by the Romantics in a variety of contexts. Goethe develops his theory of the symbol most notably in his scientific works. Schelling's approach to the Romantic symbol is firmly rooted in his philosophical writings. Coleridge articulates a Romantic notion of symbolism across his extensive literary criticism. The foundational influence of these related theories of Romantic symbolism can be seen in the artistic, literary, and scientific productions of Romantic minded individuals all over Europe in the late eighteenth and early nineteenth century. However, the nature and scope of the Romantic …

More Than One Way: How Migrants Are Able To Achieve Belonging Beyond Their Legal Status, Claudia Soto Jun 2021

More Than One Way: How Migrants Are Able To Achieve Belonging Beyond Their Legal Status, Claudia Soto

Theses and Dissertations

Is legal status a master status for migrant belonging? If not, how do other factors--such as social networks, religious participation, language and cultural familiarity--shape belonging? Over the past few years, some migration scholars have suggested that legal status is a "master status"which determines migrant outcomes (Gonzales 2015). Other literature suggests that migrant outcomes are determined by a variety of factors, asserting that migrant experiences can be better understood by studying the interaction between these factors (Enriquez 2017; Valdez and Golash-Boza 2020). Utilizing 73 semi-structured interviews with migrants in Utah, I compare the experiences of refugees, permanent migrants, temporary migrants, and …

Developing The Definite Integral And Accumulation Function Through Adding Up Pieces: A Hypothetical Learning Trajectory, Brinley Nichole Stevens Jun 2021

Developing The Definite Integral And Accumulation Function Through Adding Up Pieces: A Hypothetical Learning Trajectory, Brinley Nichole Stevens

Theses and Dissertations

Integration is a core concept of calculus. As such, significant work has been done on understanding how students come to reason about integrals, including both the definite integral and the accumulation function. A path towards understanding the accumulation function first, then the definite integral as a single point on the accumulation function has been presented in the literature. However, there seems to be an accessible path that begins first with understanding the definite integral through an Adding Up Pieces (AUP) perspective and extending that understanding to the accumulation function. This study provides a viable hypothetical learning trajectory (HLT) for beginning …

Preventing Alzheimer's: Effects Of Second Language Acquisition In Older Populations, Joshua Rhead Jun 2021

Preventing Alzheimer's: Effects Of Second Language Acquisition In Older Populations, Joshua Rhead

Undergraduate Honors Theses

Alzheimer’s disease continues to be a problem that medicine has few answers for. As a result, much research has been focused on finding a cure as well as interventions to help prevent the onset of the disease. One such intervention that has been proposed is to improve the brain’s efficiency and connectivity. A controversial method of achieving these results is through second language acquisition. Many provide evidence for or against the benefits of this intervention, but much remains unclear. Most of these studies focus on cognitive function and functional connectivity in language areas, but the default mode network, which is …

Addressing Melanoma Risk In Families, Rebecca B. Roy, Deborah O. Himes Jun 2021

Addressing Melanoma Risk In Families, Rebecca B. Roy, Deborah O. Himes

Student Works

Melanoma is one of the top 10 cancers in the United States. It is an aggressive and potentially fatal skin cancer. Up to 10% of all people diagnosed with melanoma have a positive family history of melanoma and a family history with a first degree relative can increase the risk for family members by 75%. Poor family communications often result in first degree relatives’ lack of knowledge about risk and prevention for melanoma. Considering this lack of knowledge, primary care providers have the opportunity to assess risk; teach and encourage prevention measures; teach and perform skin exams; and refer to …

Zeros Of A Family Of Complex Harmonic Polynomials, Samantha Sandberg Jun 2021

Zeros Of A Family Of Complex Harmonic Polynomials, Samantha Sandberg

Theses and Dissertations

In this thesis we study complex harmonic functions of the form f where f is the sum of a nonconstant analytic and a nonconstant anti-analytic function of one variable. The Fundamental Theorem of Algebra does not apply to such functions, so we ask how many zeros a complex harmonic function can have and where those zeros are located. This thesis focuses on the complex harmonic family of polynomials p_c where p_c is the sum of z+(c/2)z^2 and the conjugate of (c/(n-1))z^(n-1)+(1/n)z^n. We first establish properties of the critical curve, which separates orientation preserving and reversing regions. These properties are then …
