Evaluating The Effects Of Thermal Cycling On Bone (Cold-Blooded Vs Warm-Blooded), Parker Reed Brewster Aug 2022

Evaluating The Effects Of Thermal Cycling On Bone (Cold-Blooded Vs Warm-Blooded), Parker Reed Brewster

Electronic Theses and Dissertations

Thermal cycling, a global threat that is increasingly becoming more real, is a stressing event that can drastically change material properties. Thermal cycling can be used for material strengthening and optimization, but more often than that, thermal cycling is a nuisance that weakens the integrity of structures and coatings. To understand and build better designs that resist the effects of thermal cycling, we look to nature. Though warm-blooded animals regulate their body temperatures within an exceptionally tight range, cold-blooded animals experience relatively extreme temperature fluctuations, and oftentimes, in less than a 5-hour time period. In other words, cold-blooded animals experience …

The Self Compassionate Side Of Awe: The Relationship Between Awe And Self-Compassion Via Self-Diminishment And Connectedness, Rachael Marie Cavallaro Aug 2022

The Self Compassionate Side Of Awe: The Relationship Between Awe And Self-Compassion Via Self-Diminishment And Connectedness, Rachael Marie Cavallaro

Electronic Theses and Dissertations

Given that having a self-compassionate attitude is linked to positive psychological functioning, it is important to identify factors that promote self-compassion. Several self-transcendent experiences and emotions, which perceptually blur the lines between the self and others, predict self-compassion. Awe, a mixed-valance emotion defined by vastness and need for accommodation, seemed a likely candidate to promote self-compassion, as it is also a self- transcendent emotion with intra and interpersonal functions (e.g., increased humility, openness, and connection) that theory and empirical research has linked to self-compassion. Thus, we hypothesized that awe would promote self-compassion both directly and indirectly via boosted feelings of …

Design And Fabrication Of Additively Manufactured Arm Cast Using Topology Optimization, Tereza Janatova Aug 2022

Design And Fabrication Of Additively Manufactured Arm Cast Using Topology Optimization, Tereza Janatova

Electronic Theses and Dissertations

The traditional approach to casting non-operative arm fractures involves fully covering a large portion of the forearm, often including a portion of the palm. The use of gypsum plaster and plaster materials often results in cutaneous problems or in more severe cases swelling, pressure sores, or deep vein thrombosis. Other disadvantages include the weight, time it takes to harden, or the damage in contact with water. The objective of the project is to create a durable but breathable custom-made design for an arm brace that will replace the traditional solutions by overcoming their disadvantages. Several research groups and companies provide …

Empirical Essays In Law And Economics, Bright Addiyia Osei Aug 2022

Empirical Essays In Law And Economics, Bright Addiyia Osei

Electronic Theses and Dissertations

I examine the effect of laws and policies regulating the use of drugs onthe decision making of economic agents. In the first paper, I estimate the effects of legalized recreational marijuana on entry into the foster-care system by exploiting state-level variation in legalization and its timing, I estimate that legalization decreases foster-care placements by at least 10%, with larger effects in years after legalization. I find even larger decreases in admissions due to parental drug and alcohol abuse, implying that substitution towards marijuana from other substances is an important part of how legalization affects admissions. I find similar effects for …

Emotion Regulation In Migraine, Tracy Protti Aug 2022

Emotion Regulation In Migraine, Tracy Protti

Electronic Theses and Dissertations

Migraine is the third most common medical condition across the globe and a leading cause of years lived with disability due to its considerable burden. The burden is further compounded by the high prevalence of psychological comorbidities and the influence of other psychological factors on functioning. Examinations of migraine within the fear-avoidance model suggest that fear of pain (FOP) promotes maladaptive avoidance and escape behaviors, which contribute to headache-related disability. Limited research demonstrates that those with migraine engage in avoidant emotion-regulation (ER) strategies but has overlooked ER abilities beyond acceptance. The current study aimed to investigate ER in individuals with …

Bridging Souths: Interdisciplinarity And Knowledge Production In Southern Studies, Matthew David Streets Aug 2022

Bridging Souths: Interdisciplinarity And Knowledge Production In Southern Studies, Matthew David Streets

Electronic Theses and Dissertations

This thesis examines the viability of southern studies, a regional studies project on the study of the U.S. South, as an academic field of study and institutionalized site of multi-, inter-, and transdisciplinary knowledge production. Southern studies has undergone numerous turns and paradigm shifts since its institutionalization in the 1970s. These ontological, epistemological, and methodological developments have reoriented the objectives of interdisciplinary knowledge production. Despite the present permeability of disciplinary boundaries, the institutional structure and its racial, capitalist, and disciplinary hierarchies hinder communication and collaboration across disciplines and fields and between the “ivory tower” and “real world.” Understanding the impact …

Do Individuals With Functional Gastrointestinal Symptoms Experience Emotions Differently? An Examination Of Emotional Responding During A Series Of Emotion Induction Tasks, Sara Witcraft

Electronic Theses and Dissertations

Functional gastrointestinal disorders (FGIDs) are disorders of the brain-gut axis characterized by physiological and emotional disturbances, including heightened comorbidity with psychiatric disorders. Individuals with FGIDs experience difficulties with emotional processing, including the awareness, identification, and regulation of emotions. Although emotional processing is implicated in the maintenance and exacerbation of FGID pathology, literature examining these associations is limited. The current study aimed to enhance understanding of the emotional processing of individuals with FGIDs. We recruited individuals with and without FGID symptoms and examined the: (1) association between gastrointestinal distress and psychopathology; (2) association between gastrointestinal distress and emotional and physiological responsivity; …

The Effects Of Interactive Object Provisioning On Corticosterone, Stress-Related Behaviors, And Cognition In Juvenile And Adult Zebra Finches (Taeniopygia Guttata), Lucas West

Electronic Theses and Dissertations

Identification and reduction of unnecessary stress in lab animals is important for welfare, and for scientific validity. Providing animals with infrastructure and objects that encourage exercise and species-typical manipulative behaviors can help reduce stress by meeting physical and psychological needs. The effects of such "environmental enrichment" (EE) have been heavily studied in both zoo animals "where it has been shown to reduce maladaptive behaviors" and in lab animals such as rodents, where it clearly reduces stress and anxiety, dampens reactions to stressful events, and increases cognition and the volume of related brain regions. While there is some evidence that EE …

Determining Implementation Barriers For Green Stormwater Infrastructure (Gsi) Practices For Urban Flood Control, Liya Abera Aug 2022

Determining Implementation Barriers For Green Stormwater Infrastructure (Gsi) Practices For Urban Flood Control, Liya Abera

Electronic Theses and Dissertations

An increase in impervious land covers, such as asphalt and buildings from new construction and land development projects, results in cities experiencing flooding events. In 2021, the US was impacted by significant weather and climate disasters, including two flooding events and 11 severe storms. In addition to flooding events, excess runoff carries pollutants to receiving waters causing low water quality and habitat loss. To minimize flooding events and maintain the quality of receiving water bodies, stormwater runoff should be handled near its source. The installation of green stormwater infrastructure (GSI) is one sustainable method of addressing stormwater runoff problems. GSI …

Using Quantum Fluctuations To Regularize An Analytic Continuation Problem From Many-Body Physics, Lucretius Coleman Aug 2022

Using Quantum Fluctuations To Regularize An Analytic Continuation Problem From Many-Body Physics, Lucretius Coleman

Electronic Theses and Dissertations

Extracting spectral information via inversion from Quantum Monte Carlo sampled data isa difficult task. There is a need to analytically continue noisy and often incomplete imaginary-time data into the full complex domain. A new approach is proposed that uses the quantum fluctuations of spin momenta to regularize the inversion. A one-dimensional Heisenberg chain in the presence of a transverse field is first encoded with synthetic data representing several classes of spectral functions and then run through a Density Matrix Renormalization Group algorithm to find its ground state. This solution corresponds to a probable, high quality solution to the inversion. Using …
