Mechanical Characterization Of Vertically Aligned Carbon Nanotube Forest Microelectrodes For Neural Interfacing, Spencer Mcleod Roberts Dec 2023

Mechanical Characterization Of Vertically Aligned Carbon Nanotube Forest Microelectrodes For Neural Interfacing, Spencer Mcleod Roberts

Theses and Dissertations

Silicon intracortical microelectrodes arrays (MEA) provide some of the best performance for brain computer interfaces but suffer from lifetime limitations that prevent clinical adoption. A primary contributor of lifetime limitations is the chronic foreign body response (FBR) which remains active in response to the brain tissue strain caused by implanted probes during brain micromotion. Designing probes with softer materials can reduce the chronic FBR and improve device lifetime. A high-aspect ratio CNT MEA could provide several advantages as an intracortical MEA but has yet to be mechanically characterized. CNT MEAs are infiltrated with 3 degrees of carbon infiltration and mechanically …

Motives And Methodologies For Improving 3d Displays, Dylan Charles Barton

Theses and Dissertations

This work contains two key contributions to the development of 3D displays. First a successful exploratory human trial research study. By comparing multiple real displays in human trials, the factors of ease of use, time, and accuracy were able to be examined in a general setting, instead of isolated to only a specific type of 3D display. These human tests showed that 3D displays in general offer better ease of use and accuracy compared to 2D displays when showing 3D media. This differs from previous studies where only a single display was examined or theoretical papers discussing factors on paper. …

Effect Of Parenting Techniques On Anxiety In Children, Amber Burton Dec 2023

Effect Of Parenting Techniques On Anxiety In Children, Amber Burton

Student Works

As anxiety among children becomes more prevalent, understanding how parenting styles affect its development may become more relevant. Anxiety affects various aspects of individuals' lives (socially, intellectually, physically, and spiritually), adding extra challenges. Anxiety can be influenced by genetics but is also potentially impacted by the child’s environment. Evidence suggests that children whose parents display higher levels of warmth through acceptance and caring behaviors tend to experience lower levels of anxiety (Butterfield et al., 2021). Additionally, lower levels of anxiety have been found in children with parents who utilize increased levels of autonomy, giving their children the freedom to make …

The Association Between Adolescent Mindfulness, Sexual Mindfulness, And Sexual Consent: Does Parent-Child Open Or Controlling Sexual Communication Moderate?, Whitney Lenna Mcewan Dec 2023

The Association Between Adolescent Mindfulness, Sexual Mindfulness, And Sexual Consent: Does Parent-Child Open Or Controlling Sexual Communication Moderate?, Whitney Lenna Mcewan

Theses and Dissertations

In this study, I investigated how mindfulness and sexual mindfulness (i.e. awareness and non-judgment) related to sexual consent beliefs among adolescents, and how these relationships were influenced by mothers' and fathers' communication about sex. My approach was grounded in Self-Determination Theory, which posits that healthy sexuality is best achieved when self-determined sexual relationships meet the fundamental human needs of autonomy, competence, and relatedness. Previous research has suggested a positive link between mindfulness and sexual mindfulness and sexual consent beliefs among teenagers. On one hand, effective open communication between parents and children, especially regarding sensitive topics such as sexuality, can enhance …

Is This My Thing, Or Your Thing?: Differentiation Of Self As A Moderator Between Pornography Use And Marital Outcomes, Naomi Mcallister Noorda Dec 2023

Is This My Thing, Or Your Thing?: Differentiation Of Self As A Moderator Between Pornography Use And Marital Outcomes, Naomi Mcallister Noorda

Theses and Dissertations

Pornography use is fairly common in today's society, which suggests that one or even both partners of many couple relationships may use pornography. Persons with high or low levels of differentiation of self may experience relationship attachment and sexual satisfaction differently depending on their partner's pornography use. On one hand, those with high differentiation may view a partner's pornography use as the partner's issue. On the other hand, those with low differentiation may view their partner's pornography use as something they are responsible for or need to change. Using data from 1,665 couples across the United States from Wave 6 …

Where Do I Fit In God’S Plan? Mixed-Orientation Marriages In The Church Of Jesus Christ Of Latter-Day Saints, Camron Angell Dec 2023

Where Do I Fit In God’S Plan? Mixed-Orientation Marriages In The Church Of Jesus Christ Of Latter-Day Saints, Camron Angell

Student Works

Mixed-Orientation marriages (MOMs) are a complex reality of many Latter-day Saints. A MOM is when one or both partners in a relationship are either lesbian, bisexual, or gay (Kort, 2015). This paper overviews the effects on mental health and the sustainability of MOMs. Research suggests that MOMs have a negative effect on mental health, and LGB members are much less likely to get help from mental health professionals due to stigma and fear of rejection (Dyer et al., 2023; Legerski et al., 2016; McGraw et el., 2023). MOMs are also up to 30% more likely to end in divorce (Dehlin, …

Moving On: An Overview Of Approaching Trauma Through Dance/Movement Therapy, Eliza Barber Dec 2023

Moving On: An Overview Of Approaching Trauma Through Dance/Movement Therapy, Eliza Barber

Student Works

Dance/Movement Therapy (DMT), an approach meant to facilitate holistic integration, has been historically associated with treating symptoms of trauma. Because it is a relatively new field, many questions still remain regarding appropriate interventions. In this extensive review of existing literature on the topic, I explored how DMT is applied in relation to Post-Traumatic Stress Disorder, culture-specific trauma and oppression, multigenerational trauma, and developmental trauma. Additionally, I delved into interventions with specific populations including refugees and young people. To identify the 26 items of literature referenced in this review, I conducted searches with appropriate terms on two scientific databases and filtered …

Finding Words For God: Poetic Foraging In Louise Glück's The Wild Iris, Rachel Cardall Dec 2023

Finding Words For God: Poetic Foraging In Louise Glück's The Wild Iris, Rachel Cardall

Theses and Dissertations

The primary speaker of Louise Glück's The Wild Iris is a wanderer in her own garden. She relentlessly searches for God among her foxgloves and daisies, straining to hear God's voice. Two other speakers, God and the collective plants of the garden, offer their perspectives without acknowledgement by the human speaker. Many critics read these two other speakers as, in fact, narcissistic projections of the human speaker, a God and a world made in her own image. In this thesis, I clarify that the kind of narcissistic projection that occurs in The Wild Iris is actually productive for genuine spiritual …

Design And Fabrication Of Transparent Ultrasonic Transducers For Optoelectronic Applications, Stephen Colby Warren Dec 2023

Design And Fabrication Of Transparent Ultrasonic Transducers For Optoelectronic Applications, Stephen Colby Warren

Theses and Dissertations

Acoustic levitation utilizes general principles of ultrasonics to trap particles in midair without external support. This is done by creating an array of ultrasonic transducers to propagate sound waves to a focused point in space. In order to optimize the particle trap it is necessary to design transducers that can produce enough sound to create pressure pockets. In this work I examine the fundamental principles of acoustics by testing the sound pressure levels (SPL) of a known transducer in both air and water mediums. A comparison between domed and bimorphed transducers are also examined. Experimentation was performed on the feasibility …

Lcc Mse Walls, Joel Smith Dec 2023

Lcc Mse Walls, Joel Smith

Theses and Dissertations

Lightweight cellular concrete (LCC) is mainly a mixture of water, cement, and foam bubbles. LCC generally has a cast density between 20-60 pcf and an air content between 49-84%. LCC is often used as a fill material because it has a low unit weight which reduces settlement. LCC is increasingly being considered as a backfill behind Mechanically Stabilized Earth (MSE) walls and embankments. Although engineers are using LCC in MSE walls or free face walls (MSE wall without the concrete panels or reinforcements), there is presently a lack of information regarding the performance and behavior of LCC to guide them. …

Once Upon A Time, Again: Exploring The Function Of Fairy Tale Retellings, Mackenzie A. Parsons Dec 2023

Once Upon A Time, Again: Exploring The Function Of Fairy Tale Retellings, Mackenzie A. Parsons

Theses and Dissertations

With the invention of the printing press, fairy tales became limited by the idea of an "original" (Pettitt, 2009; Blamires, 2003). However, in the past century, the retelling and changing of fairy tales has become incredibly popular in all forms of media, such as print, film, ballet, musicals, etc. Despite Western populations' familiarity with these tales, the demand for such retellings continues to rise, with the storytellers finding great financial success with each "new" version they provide. Researchers have many varying opinions on the reasons for such intense responses to retold fairy tales, but there is a gap of research …

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings Dec 2023

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings

Theses and Dissertations

Stockpile volumes are monitored by their companies as the product (i.e., aggregate, soil) is moved in and out of the facilities to ensure minimal product loss. Companies are mandated to report product movement to the government to ensure that the aggregate and soil is going where it is supposed to go. Many tools are used to monitor stockpile volumes including truck scales (to weigh incoming and outgoing trucks), light detection and ranging (LiDAR), Global Navigation Satellite System (GNSS) equipment, and unmanned aerial vehicle (UAV) photogrammetry. These processes give a good estimate of stockpile volumes. Errors in these estimates typically come …

Lack Of Quality Media Representation For Transgender Women, Seth Ririe Dec 2023

Lack Of Quality Media Representation For Transgender Women, Seth Ririe

FHSS Mentored Research Conference

“Transgender” is a term used to describe people whose gender identity is incongruent with their sex assigned at birth. This brief discusses transgender women (that is, transgender people whose gender identity is female) and their experiences with popular narrative media representation. Transgender women are improperly or under-represented due to a lack of transgender media creators, the American public opinion of transgender women, and audience fragmentation, which keeps media featuring transgender women away from wider audiences. As a result of the lack of quality media representation for transgender women, stereotypes surrounding transgender women become more prevalent and transgender women may experience …

Invisibility, Confusion, And Adjustment:Exploring The Grief Experience Of Grandmothers Supporting Their Bereaved Grandchildren, Jordan Robertson

Theses and Dissertations

Bereavement is painful at any time of life. For young children experiencing bereavement, grandmothers are often the first line of defense. Grandmothers are frequently called upon when their family members experience an out-of-order death, and while they are willing to provide care, grandmothers don't always know the best way forward. This qualitative study sought to learn more about the grief experiences of 22 grandmothers who had lost a family member prematurely through semi-structured interviews and Interpretive Phenomenological Analysis. Findings suggest (a) grandmothers experience layered grief in that they grieve the loss of the family member, experience the pain of the …

Pronouns On Resumes And The Perceived Hireability Of Transgender And Non-Binary Candidates, Seth Ririe Dec 2023

Pronouns On Resumes And The Perceived Hireability Of Transgender And Non-Binary Candidates, Seth Ririe

FHSS Mentored Research Conference

Transgender and non-binary (TGNB) individuals are more likely to be in poverty and be unemployed than cisgender individuals. This study seeks to understand if placing one’s pronouns on their resumes creates a barrier to equal employment for the TGNB population. I do so through two means: surveying TGNB individuals (n=63) on their worries and experiences with placing their pronouns on their resumes and conducting an RCT (n=654). The RCT assigned participants to 1 of 8 pronouns which shared all information save the candidates’ name (either masculine or feminine) and pronouns (he, she, they, or no pronouns). I find that TGNB …
