Application Of High-Deflection Strain Gauges To Characterize Spinal-Motion Phenotypes Among Patients With Clbp, Spencer Alan Baker
Application Of High-Deflection Strain Gauges To Characterize Spinal-Motion Phenotypes Among Patients With Clbp, Spencer Alan Baker
Theses and Dissertations
Chronic low back pain (CLBP) is a nonspecific and persistent ailment that entails many physiological, psychological, social, and economic consequences for individuals and societies. Although there is a plethora of treatments available to treat CLBP, each treatment has varying efficacy for different patients, and it is currently unknown how to best link patients to their ideal treatment. However, it is known that biopsychosocial influences associated with CLBP affect the way that we move. It has been hypothesized that identifying phenotypes of spinal motion could facilitate an objective and repeatable method of determining the optimal treatment for each patient. The objective …
Time-Dependent Strain-Resistance Relationships In Silicone Nanocomposite Sensors, Alex Mikal Wonnacott
Time-Dependent Strain-Resistance Relationships In Silicone Nanocomposite Sensors, Alex Mikal Wonnacott
Theses and Dissertations
Flexible high-deflection strain gauges have been demonstrated as cost-effective and accessible sensors for capturing human biomechanical deformations. However, the interpretation of these sensors is notably more complex compared to conventional strain gauges, partially owing to the viscoelastic nature of the strain gauges. On top of the non-linear viscoelastic behavior, dynamic resistance response is even more difficult to capture due to spikes in resistance during strain changes. This research examines the relationships between stress, strain, and resistance in nanocomposite sensors during dynamic strain situations. Under the assumption that both macroscopic stress and resistance are governed by microscopic stress concentrations at the …

Can Podcasts Reduce Affective Polarization By Combating Contextomy Via Long-Form Discussions?, Luke D. Hartvigsen
Can Podcasts Reduce Affective Polarization By Combating Contextomy Via Long-Form Discussions?, Luke D. Hartvigsen
Theses and Dissertations
There is a growing concern regarding political polarization in the United States, most notably the phenomenon of affective polarization, which is when polarization increases negative feelings toward those who differ politically. The current dissertation project sought to address this issue by testing a media intervention using podcasts. Podcasts allow speakers to talk for hours uninterrupted through long-form discussions, whereas other media often edit political discussions to the point of contextomy (editing and framing a quote out of its proper context). Podcasts were created for this dissertation which differed on the political message of the podcast guest (conservative vs. liberal), and …

Psychotherapy Client Termination Patterns And Outcomes: A Large Follow-Up Study, Including Zero-, One-, And Two-Session Cases, Adam Victor Mcdonald
Psychotherapy Client Termination Patterns And Outcomes: A Large Follow-Up Study, Including Zero-, One-, And Two-Session Cases, Adam Victor Mcdonald
Theses and Dissertations
Empirical research examining psychotherapy clients' post treatment outcomes for all case lengths and their reasons for discontinuing treatment is limited in the literature, particularly for shorter case lengths. Research indicates that clients with zero-, one-, and two-session case lengths are the most common in psychotherapy (Howard et al., 1986; Nielsen et al., 2016; Phillips, 1985; Phillips 1987); and yet, little is known about these clients. The purpose of this study is to better understand these termination patterns and outcomes for the most common case lengths. Outcomes were measured with the Outcome Questionnaire-45 total score (OQ-45; Lambert et al., 2004). Client …
Time Spent Jogging/Running And Biological Aging In 4,458 U.S. Adults: An Nhanes Investigation, Christina Michelle Blackmon
Time Spent Jogging/Running And Biological Aging In 4,458 U.S. Adults: An Nhanes Investigation, Christina Michelle Blackmon
Theses and Dissertations
Telomere length is a good index of cellular aging. Longer telomeres are predictive of longer life, and healthy lifestyles are associated with longer telomeres. This study explored the relationship between time spent jogging or running each week and leukocyte telomere length (LTL) in 4,458 randomly selected U.S. adults. The association was studied using data collected by the National Health and Nutrition Examination Survey (NHANES), and a cross-sectional design. Total weekly jog/run time was calculated from survey responses. From the minute totals, three categories were formed: <10 minutes/week, 10-74 minutes/week, and ≥75 minutes/week. Adults in the third category met the U.S. guidelines. Data were analyzed using one-way ANOVA. Partial correlation was used to adjust for differences in potential mediating factors, including demographic and lifestyle/medical factors. In the total sample, after adjusting for all the potential covariates, mean LTL significantly differed across the 3 jog/run categories (F=4.1, P=0.0272). Specifically, adults who met the guidelines via jogging and/or running had significantly longer telomeres than adults who performed no jogging/running. Adults in the middle category did not differ from the other two categories. A minimum of 75 minutes of jogging/running weekly is predictive of longer telomeres when compared to adults who do not jog or run regularly.

Can A Congregation Make A Difference? The Relationship Between Social Support And Latter-Day Saint Lgbtq+ Adolescent Well-Being, Aubrey Bardsley
Theses and Dissertations
This study explores the relationship between social support at church and the well-being of adolescents who currently or previously belonged to The Church of Jesus Christ of Latter-day Saints (LDS, formally known as Mormon), differentiating between LGBTQ+ and non-LGBTQ+ adolescents. Past studies show that social support is negatively related to suicidality for adolescents. However, open questions remain about if this relationship is similar for LDS adolescents who identify as LGBTQ+ compared to those who do not. To test this question, I used data from the Family Foundations of Youth Development, a project that randomly sampled adolescents from Utah, Arizona, and …
Error Processing In Adolescents With A Mild Traumatic Brain Injury (Mtbi): A Longitudinal Study, Tanner J. Jensen
Error Processing In Adolescents With A Mild Traumatic Brain Injury (Mtbi): A Longitudinal Study, Tanner J. Jensen
Theses and Dissertations
Error processing, a neural process critical to adaptive learning during adolescence, may be disrupted by mild traumatic brain injury (mTBI). Both cross-sectional and longitudinal studies of adults following mTBI indicate a variable impact of mTBI on neural correlates of error processing, including the error related negativity (ERN) and post error positivity (Pe) components of the scalp-recorded event-related potential (ERP). Existing studies of mTBI in adolescents indicate significantly decreased ERN amplitudes and nonsignificant differences in Pe amplitude between mTBI and control groups. However, no longitudinal studies of adolescents with mTBI are available to date despite the importance of these processes. We …

Investigating Which Muscles Are Most Responsible For Tremor Through Both Experimental Data And Simulation, Daniel Benjamin Free
Investigating Which Muscles Are Most Responsible For Tremor Through Both Experimental Data And Simulation, Daniel Benjamin Free
Theses and Dissertations
Tremor affects millions of people and many patients desire alternative treatment options to medication or neural surgery. Peripheral suppression techniques are gaining greater use, but are currently applied in a trial-and-error method. To optimize these techniques, the muscles most responsible for an individual patient's tremor need to be identified. In this dissertation, I explored two parallel paths that both could aid in identifying muscles responsible for tremor. The first method utilizies measured data and a technique (coherence) that quantifies the frequency dependent correlation between two signals. Using coherence to identify muscles contributing to tremor requires at least two parts: an …
Remote Sensing Of Residential Landscape Irrigation In Weber County, Utah, Annelise Marie Capener
Remote Sensing Of Residential Landscape Irrigation In Weber County, Utah, Annelise Marie Capener
Theses and Dissertations
Irrigation of residential properties in urban settings is typified by small and irregular areas, many untrained water users, limited end-use metering, and differing groundcover in contrast to agricultural settings. This makes analyzing irrigation patterns to promote efficient water use challenging. Analysis of Irrigation by Remote Sensing (AIRS) combines multispectral aerial imagery, evapotranspiration data, and ground-truthed measurements to overcome these challenges. We demonstrate the application of AIRS on eight neighborhoods in West Haven, Utah, using 0.6 m National Agriculture Imagery Program (NAIP) and 0.07 m drone imagery, reference evapotranspiration (ET), and water meter data from Weber Basin Water Conservancy District (WBWCD). …

Advancing Single-Cell Proteomics Through Innovations In Liquid Chromatography And Mass Spectrometry, Kei Grant Isaac Webber
Advancing Single-Cell Proteomics Through Innovations In Liquid Chromatography And Mass Spectrometry, Kei Grant Isaac Webber
Theses and Dissertations
Traditional proteomics studies can measure many protein biomarkers simultaneously from a single patient-derived sample, promising the possibility of syndromic diagnoses of multiple diseases sharing common symptoms. However, precious cellular-level information is lost in conventional bulk-scale studies that measure tissues comprising many types of cells. As single cells are the building blocks of organisms and are easier to biopsy than traditional bulk samples, performing proteomics on a single-cell level would benefit clinicians and patients. Single-cell proteomics, combined with mass spectrometry imaging, can be used to analyze cells in their microenvironment, preserving spatial information. We have previously used laser-capture microdissection to isolate …
Robot Proficiency Self-Assessment Using Assumption-Alignment Tracking, Xuan Cao
Robot Proficiency Self-Assessment Using Assumption-Alignment Tracking, Xuan Cao
Theses and Dissertations
A robot is proficient if its performance for its task(s) satisfies a specific standard. While the design of autonomous robots often emphasizes such proficiency, another important attribute of autonomous robot systems is their ability to evaluate their own proficiency. A robot should be able to conduct proficiency self-assessment (PSA), i.e. assess how well it can perform a task before, during, and after it has attempted the task. We propose the assumption-alignment tracking (AAT) method, which provides time-indexed assessments of the veracity of robot generators' assumptions, for designing autonomous robots that can effectively evaluate their own performance. AAT can be considered …
