The Role Of Caloric Intake On Achilles Tendon Health In Pre-Professional Ballet Dancers, Annie G. Smedley

Theses and Dissertations

Background: Achilles tendinopathy is a common and debilitating condition among female ballet dancers due to the large repetitive loading forces placed on their Achilles tendons during rehearsals and performances. Tendon health problems in females are exacerbated by a lack of understanding about how energy availability influences tendons. Ballet dancers, as aesthetic athletes, are vulnerable to low energy availability and can enter a spectrum disorder, relative energy deficiency in sport, that consists of low energy availability (with or without disordered eating), menstrual cycle dysfunction, and low bone mineral density (BMD). Aims: 1) To investigate the relationship between insufficient caloric intake and …

Catchment Water Storage Mediates River Flow Sensitivity To Climate Change, Brian Charles Brown

Theses and Dissertations

As patterns of precipitation and evapotranspiration change, human water security and aquatic ecosystem health depend on understanding how catchment characteristics interact with climate to control river flow. We tested factors that mediate sensitivity of river flow to fluctuations in climate using a set of 1,148 data-rich, climate diverse catchments in various parts of the world from 2001-2020. We extrapolated these results to an additional 2,012 catchments with sparser data. Using features such as vegetation, land use, hydrology, and local climate, we found that catchments with high aridity to runoff ratios (Fuh's parameter) had 380% higher runoff sensitivity to fluctuations in …

The Relationship Of Self-Determination And Self-Construal On College Adjustment, Rayhane Baniardalan

Theses and Dissertations

This study investigated the interplay between self-construal (individualistic vs. collectivistic), basic psychological needs (autonomy, competence, relatedness), and college adjustment among a diverse student population. Contrary to expectations, self-construal did not directly predict overall adjustment. However, horizontal individualism (valuing personal achievement over group success) was negatively associated with adjustment. Supporting self-determination theory (SDT), all three basic psychological needs were positively correlated with all three domains of college adjustment (academic, social, and psychological). The strongest correlations were between relatedness and social functioning, and competence and social functioning. Racial differences in adjustment could not be examined due to sample limitations. Interaction effects between …

The Evaluation Of Non-Specific Risk Indicators In Improving Detection Of Psychosis-Spectrum Liability, Thomas W. O'Kane

Theses and Dissertations

Psychosis-spectrum disorders remain a leading cause of disability for both individuals and society, with early identification and prevention efforts representing a promising avenue of research for addressing these concerns. One potential impediment to improving early risk identification is the historical focus on indicators thought to be exclusive to the psychosis-spectrum. This focus often comes at the expense of non-specific risk factors (e.g., disrupted sleep, adverse childhood experiences) which contribute to the risk of developing psychosis as well as other mental illnesses. Research suggests the inclusion of these non-specific factors may improve our ability to identify those at risk. The present …

Perceptions Of Violent Content And Their Relationships On Aggressive Behavior: The Effects Of Implicit Beliefs On Aggression In Relation To Video Content, Logan Mccombs

Theses and Dissertations

Previous research shows that consuming violent media can lead to increased aggression in thoughts, feelings, and behaviors. Several other factors also contribute to such behaviors but have not been thoroughly studied including implicit beliefs about aggression in relation to media content. This two-part study consists of (1) an exploratory iterated principal-factor method to create an implicit belief measure about consuming violent media in conjunction with correlational analyses and (2) between subjects hierarchical linear regression models to determine what effects implicit beliefs have on subsequent aggression after participants view either a violent of nonviolent video, while controlling for violent media consumption …

The Influence Of Religious And Political Discrepancies On Parent-Adolescent Social Cohesion, Emily De Schweinitz Taylor

Theses and Dissertations

American youth are leaving organized religion at historical levels. Given that religious and political similarity (consensual solidarity) tends to strengthen affectual solidarity (emotional connection) in parent-adolescent dyads, decreasing adolescent religiousness and increasing political disagreements may threaten family social cohesion. However, during adolescence, youth empathy skills tend to increase and adolescents’ conflict with their parents tends to eventually subside. Based on principles outlined in intergenerational family solidarity theory, I hypothesized that adolescent empathy skills and authoritative parenting style would buffer the negative relational effects of religious and political discrepancies within the parent-adolescent relationship. I used Waves 2-4 (referred to as Times …

The Role Of Instructors In Fostering A Sense Of Belonging For Native Hawaiian And Pacific Islander University Students, Kehaulani Oleole Malzl

Theses and Dissertations

An alarmingly high level of Native Hawaiian and Pacific Islander (NHPI) college students in the United States end up dropping out of secondary education institutions. One important predictor of academic success and retention at the secondary level is student sense of school belonging.

A snowball sample of 97 NHPI students participated in 18 focus groups that included students from various islands and ethnicities in Oceania who were attending one U.S. university in the Pacific Rim. Focus group data were transcribed …

Spatiotemporal Variation In Regeneration And Herbivory In Stable And Seral Aspen Stands, Sterling Burgess Kerr

Theses and Dissertations

Aspen forests are strongly influenced by disturbances like fire and ungulate herbivory, which can impact plant community composition and succession. Human activities alter these disturbances, affecting their timing, extent, and severity. Chapter 1 explores the effects of large-scale prescribed fire and mechanical thinning treatments on aspen regeneration and vulnerability to ungulate herbivory. Results show that while aspen regeneration was hindered by chronic ungulate herbivory in untreated areas, mechanical thinning and prescribed fire stimulated aspen regeneration. However, mechanically thinned plots were vulnerable to ungulate herbivory, with only prescribed fire having reduced browsing. Chapter 2 investigates herbivory patterns and recruitment across stable …

Associations Between Young Children's Problematic Media Use And Physiological Regulation -- Does Temperament Act As A Mediator?, Noah Alexander Chojnacki

Theses and Dissertations

Given the ubiquity of media use, especially among young children, the current study examines the impact of problematic media use (PMU) on children's (N = 418, M age = 53.62 months, SD = 3.38 months, M and SD are taken from the full sample of 418 children) physiological functioning. With previous studies reporting relations between media use, temperament, and physiological regulation, it was hypothesized that children with greater levels of PMU would have lower levels of baseline respiratory sinus arrhythmia (RSA; a measure of physiological regulatory capacity). It is further hypothesized that, higher levels of negative affect, and lower levels …

Association Between Handgrip Strength And Muscle Mass In Children 6 To 10 Years Old, Samantha Velázquez Villalobos

Theses and Dissertations

Measuring body composition in children is important due to the rise of childhood obesity and changes that occur during pre-pubertal years. Sarcopenia, defined as a muscle mass loss and function, is increasingly recognized in pediatric populations, particularly in childhood obesity. Therefore, it is necessary to have measurements which not only provide an overall picture of body composition, but that can distinguish between muscle and fat mass. Methods of body composition such as Dual Energy X-ray Absorptiometry (DEXA) provide accurate assessments of body composition, but they are resource-intensive and impractical for routine monitoring in clinical or community settings. To address this, …

Tunable Dual-Phase Dual-Drug Delivery System Using A Plga Microparticle/Pva Hydrogel Composite, Timothy John Eck

Theses and Dissertations

Current drug-eluting coatings have demonstrated controlled long-term, sustained release but have only tried to mitigate short-term burst release as a negative side effect. For applications like wound healing, there is a need for a drug-eluting coating which is adjustable in both short- and long-term release, independent of each other. We present a tunable dual-phase dual-drug delivery coating composed of drug-loaded polymer microparticles and drug-loaded hydrogel which can control short term and long term release individually in this study. This coating was created using lidocaine and dexamethasone encapsulated in poly(D,L-lactide-co-glycolide) particles combined with lidocaine- and dexamethasone-loaded poly(vinyl alcohol) hydrogel.

Distinguishing Between Symptom Presence And Severity Using A Two-Part Sequential Model, Luiza Ferreira Pradera

Theses and Dissertations

Most symptom measures either implicitly or explicitly distinguish between symptom presence and symptom severity. For example, item 2 on the PHQ-9, a commonly used measure of depressive symptoms, asks respondents to rate how much they have been 'feeling down, depressed, or hopeless.' The response options are 0 (Not at all), 1 (Several Days), 2 (More than half the days), and 3 (Nearly every day). Answering 0 indicates that the symptom is not present, and any response greater than 0 suggests the symptom is present. Higher values indicate higher severity of the symptom. Although the response options distinguish between symptom presence …

Multiscale Characterization Of Dislocation Development During Cyclic Bending Under Tension In Commercially Pure Titanium, Nathan R. Miller

Theses and Dissertations

Continuous bending under tension (CBT) has been shown to increase room temperature elongation-to-failure (ETF) in various sheet metals past that of simple tension (ST). In commercially pure titanium (CP-Ti) Grade 4, up to 3x extended elongation over ST has been achieved. A greater understanding of deformation mechanisms in CBT would allow for its elongation-enhancing effects to be more fully exploited in HCP and other metals, creating potential for new forming strategies. While most of the extended ETF has been attributed to delayed localization via incremental deformation inherent to the CBT process, together with compressive stabilization and relaxation of mechanical strain …
