"Vampire Plastics": An Investigation Of Poly(Olefin Sulfone) Depolymerization And Its Dust Mitigation Abilities, Alexandra Kathryn Kanani Gallion Stapley

Theses and Dissertations

The ubiquity of particulate contamination requires dust mitigation techniques to provide low-scatter surfaces and edges on sensitive optical devices in space. Poly(olefin sulfone)s have been shown to photodegrade with the assistance of a photobase generator when exposed to UV light (254 nm) and heat (120 °C). These polymers may be useful for minimizing dust on optical surfaces for space applications. However, their behavior in vacuum has not been fully characterized. We synthesized poly(2-methyl-1-pentene sulfone) (PMPS) and poly(1-hexene sulfone) (PHS) with and without a photobase generator. We studied the photodegradation (172 nm or 254 nm) of thin films in vacuum. Spectroscopic …

The Sound Of Silence: Listening For God In Cormac Mccarthy's The Road, Brittany Higgins Maloy

Theses and Dissertations

In the decimated and silent post-apocalyptic setting of Cormac McCarthy's The Road, the main characters spend a significant amount of time listening to silence, listening for signs of danger, but also listening for the voice of God. Many have discussed the hopeless nihilism juxtaposed with the heavy use of Christian iconography in the novel classifying it within one of these dichotomies or somewhere on the spectrum in between. This paper argues that the hopelessness and stark silence is required to reveal hope and the opportunity to hear God's voice. To demonstrate my argument, I define the characteristics of silence, stillness, …

Communication Between Young Adults And Their Siblings With Autism, Shane Morgan Petersen

Theses and Dissertations

As adolescents transition into young adults, many changes take place within family relationships as young adults move away from home. Young adults may be living away from parents and siblings for the first time and will establish communication patterns that can affect the rest of their life (citation). Relationships largely rely on communication in which young adults and their siblings with autism may experience changes in communication patterns as they move away from home. This study examined six young adults who all have a sibling with autism with whom they are no longer living. An examination of how close these …

The Voice As Identity: How Opera Has Influenced Dubbing In Italy And The United States, Brynn Allison Staker

Theses and Dissertations

An enduring Italian tradition of celebrating the voice and the Italian language as seen by the Italian perception and interest in opera has created an environment of celebration for Italian dubbers. The long-established history of opera in Italy, as well as the modern reception of Italian opera, have effectively placed the voice at the forefront of the Italian entertainment industry. This can be seen through an examination of the careers of Italian dubbers and the success that they saw in their industry. The United States did not have a longstanding operatic tradition, and when opera was introduced it was under …

Chromosome-Scale Assemblies And A Pangenome Reveal Ltr Repeat Dynamics As A Major Driver Of Genome Evolution In Chenopodium, Kate E. Jaggi

Theses and Dissertations

The genus Chenopodium, which comprises around 150 species globally, is characterized by its wide geographic distribution and ecological adaptability, particularly in temperate regions. Some species, such as Chenopodium quinoa and Chenopodium pallidicaule, have served as domesticated staple crops in the Andean region of South America for centuries, valued for their robust nutritional profile and adaptability to adverse environmental conditions. In contrast, wild Chenopodium species exhibit broad geographic distributions and diverse niche adaptations, functioning as reservoirs for beneficial traits, including disease resistance and climate hardiness, essential for enhancing domesticated crops through introgression and breeding efforts. However, taxonomic classification within the genus …

Ip&T 372 Redesign, Christan Hatch-Garcia

The purpose of this work is to evaluate numerical simulations of focused ultrasound (FUS) on their predictions of the focal location. Those simulations are compared to clinical magnetic resonance acoustic radiation force imaging (MR-ARFI) data collected during in vivo treatment of breast tumors. Methods: The focal location was evaluated prior to MRgFUS treatment …

Procedural Pre-Training For Visual Recognition, Connor S. Anderson

Theses and Dissertations

Deep learning models can perform many tasks very capably, provided they are trained correctly. Usually, this requires a large amount of data. Pre-training refers to a process of creating a strong initial model by first training it on a large-scale dataset. Such a model can then be adapted to many different tasks, while only requiring a comparatively small amount of task-specific training data. Pre-training is the standard approach in most computer vision scenarios, but it's not without drawbacks. Aside from the cost and effort involved in collecting large pre-training datasets, such data may also contain unwanted biases, violations of privacy, …

Differential Effects Of Social Media On Body Esteem: An Ecological Momentary Assessment On Weight Satisfaction And Muscularity Importance, Megan Van Alfen Brown

Theses and Dissertations

This study investigated how social media use is related to body esteem (particularly weight satisfaction and muscularity importance) in adolescents. We conducted a 17-day Ecological Momentary Assessment study among 183 adolescents (12–17 years, 58% girls). Each adolescent reported on his/her social media use, weight satisfaction, and muscularity importance four times per day (68 assessments per participant; 6,863 completed in total). Using a person-specific, N=1 method of analysis (Dynamic Structural Equation Modeling), we found that at the between-person level, social media use is not associated with lower satisfaction with one’s weight and greater importance of looking masculine. At the within-person level, …

Factors Surrounding Mental Health Well-Being For Male Adolescent Pacific Islanders, Melia Fonoimoana Garrett

Theses and Dissertations

Despite increasing mental health concerns, individuals from the Pacific Islands largely do not utilize the resources available to them (National Survey of Drug Use and Health, 2020). This is of particular concern among male adolescents within the population who are more at risk of mental health concerns. An interpretative phenomenological analysis focus group study was conducted in person with male adolescent Pacific Islanders (PI; ages 14–16) residing in one Western state (n = 3). Male adolescents reported that admitting to mental health concerns would greatly limit their academic, career, and personal ambitions due to the stigma attached. They also discussed …

Validating The Sexual Anxiety Inventory, Allie Smith

The Sexual Anxiety Inventory (SAI) is a psychometric tool intended to measure sex-related anxiety for individuals in many different relationship stages and irrespective of sexual experience. A sample of 419 participants aged 18 to 76 responded to the items of the SAI as well as measures of generalized anxiety, depression, sexual sensation seeking, sociosexuality, and personality. After factor analysis, five factors were determined to have unique properties while being interpretable. A series of correlational testing between these factors and the measures of anxiety, depression, sexual sensation seeking, and sociosexuality demonstrated the strength of SAI factors as measurement tools. Exploratory correlations …

What The Eye Doesn't See: The Power Of Non-Ocularcentric Engagement In Museum Learning, Sophie J. Houghton

Undergraduate Honors Theses

Museums are unique spaces of teaching and learning. Museum exhibits transcend the constraints of classroom learning by leveraging visitors’ curiosity and allowing for increased learning autonomy. However, this learning often comes solely through visual interaction, due to museums’ role in preservation and protection of their collection. Though visual-based learning is common in museums and in Western education at large, multisensory elements cement learning autonomy and prompt visitors to learn through play. These principles are exemplified through children’s’ museums, science museums, and museum adaptations for blind and low-vision visitors. Through multisensory adaptations, traditional museums can transform their impact on visitors. This …

Composing Pedagogically-Informed Choral Literature For Adolescent Males, Rachel Olson

Undergraduate Honors Theses

The “missing males” phenomenon, the disparity between males and females enrolled in choral ensembles in junior high and high school settings, has long been a concern among music educators (Koza, 1993). This gap in choral enrollment is often attributed to challenges associated with the male changing voice, prescribed gender roles, and a lack of suitable repertoire (Ayres, 2020, Lucas, 2011; Hawkins, 2015). The decline of male choral singers poses significant obstacles to fostering balanced and inclusive choral communities. Through an extensive review of existing literature and pedagogical insights from choral experts, this paper reviews the physiological changes associated with voice …

This study investigated the efficacy of culturally adapted bibliotherapy in promoting resilience among American Samoan children aged 5-13 years in response to high adolescent suicide rates in the Pacific Islands and the need for culturally adapted and supportive interventions grounded in mental health wellness. Bibliotherapy, particularly the identification with story characters, has been recognized for bolstering mental wellness, resilience, and emotional regulation in children. In this research, the children's response to bibliotherapy was measured through card sorting and forced-choice exercises, assessing their engagement with literature mirroring their experiences. The materials were developed in collaboration with Samoan cultural brokers on island …

The Institutionalization Of Jazz Pedagogy As Observed In The Greater Salt Lake Area Of Utah, Jens Watts

Undergraduate Honors Theses

Although traditionally an oral art form, the learning and teaching of jazz music has undergone a shift towards institutionalization and formalization in the last fifty years, principally in the form of method books and the presence of jazz in educational institutions. This study documents this trend by a comparison of jazz pedagogy experienced by and used by professional musicians in Utah with that which is recorded in Paul Berliner’s Thinking in Jazz. The informality of education for Berliner’s interlocutors contrasts starkly with the institutionalized education of most of the participants in this study.

One Size Does Not Fit All: Creating Educational Equity For Later Diagnosed Autistic Women, Naomi Julian

Undergraduate Honors Theses

Autism research focuses on the externalized behaviors usually associated with the male phenotype of autism with little representation of the internalized behaviors associated with the female phenotype of autism. Even more so, there is little research involving later diagnosed autistic women — especially women of color. Beyond this, non-white individuals have been marginalized within the sphere of education, and their marginalization is exacerbated by an autism diagnosis.

In the realm of schooling, the relationship between race, gender, and disability lacks investigation. In this exploratory study, I draw upon qualitative data from interviews of 17 racially diverse autistic women ages ranging …
