Association Of Hiv Status And Other Minoritized Identities With Psychiatric Diagnoses Among Transgender And Gender Diverse Individuals In The All Of Us Research Program, Fanghui Shi

Theses and Dissertations

Background: Transgender and gender diverse (TGD) people, whose gender identities or expressions differ from the sex assigned at birth, are disproportionately affected by adverse health outcomes, including various psychiatric diagnoses such as depression, anxiety, stress, and substance use disorders. The Gender Minority Stress Model emphasizes that TGD people face both proximal stressors at a personal/individual level (e.g., internalized stigma) and distal stressors at a societal level (e.g., discrimination) due to their minority status, which largely contributes to their increased risk of psychiatric diagnoses. Despite these health disparities, there is a paucity of gender identity data collected in large population-based health …

Evaluation Of Mechanism Of Action And Toxicity Of Novel Psychoactive Substances (Nps) Identified As Cannabinomimetics, Robert Michael Sears

The Social Influence Network Model Of Performance Expectations, Jingwen Zhong

Theses and Dissertations

Disagreement among group members on each other’s status and competence has been found to negatively impact group performance. However, in theories, it is oftentimes assumed that group members have common perceptions of each other’s competence, or in other words, have a consensus on performance expectations. Recognizing the importance of disagreement on performance expectations, in this dissertation I argue that individuals are subject to the self-serving bias and can develop different performance expectations based on the same status information. The results of an online experiment show that individuals tend to think highly of themselves in both status-homogeneous and status-heterogenous situations, and …

Calibration And Use Of The Transparency Tube As An Estimate Of Turbidity: An Analysis Of Factors Controlling Light Attenuation In Estuarine Waters, Makenna Leigh Thompson

Theses and Dissertations

The transparency tube is low-cost, portable, and easy to use to measure the transparency or clarity of the water. Filling the tube with water creates a small-scale water column where water will be slowly drained out of the bottom until the Secchi disk at the bottom of the tube is visible from the top opening, and the depth of the remaining water in the tube is recorded in centimeters. Unlike traditional Secchi disk measurements, the advantage of this instrument is that sampling depth in highly turbid waters is possible with a centimeter scale resolution. Transparency tube measurement, through careful calibrations, …

Reimagining Utopia In Post-Utopian China: Chinese Science Fiction And The Reinvention Of Cultural Tradition, Dan Luo

Theses and Dissertations

Despite the end of China’s socialist dream in the late 1970s, utopian expressions about the nation’s rise and progress have continued to emerge in official and popular imaginaries. These expressions find an outlet in the newly popularized sci-fi genre, and especially in literary experiments that evoke cultural resources ranging from premodern and early modern historical and literary records of scientific achievements to figures, tropes, and myths in classical tales, vernacular novels, and ethnic traditions. These experiments at times validate and support, and at times challenge and subvert the nationalist, progressive, and utopian narratives of the state. This dissertation investigates the …

Examining Risk Factors For Early-Onset Breast Cancer, Jennifer Grace Taylor

Theses and Dissertations

Introduction: There have been great advancements in screening and in the identifying of risk factors associated with breast cancer, however, there is a lack of information of these factors in women with breast cancer occurring under the age of 45, known as early-onset breast cancer (EOBC). EOBC is often found at later stages, negatively impacting young women’s careers, family planning, and mental health. Additionally, because of the health disparities that exist within the U.S. health care system, women belonging to racial and ethnic groups, specifically young Black women, tend to have poorer outcomes and higher mortality rates of EOBC compared …

Development Of A Large Format Additive Manufacturing System Based On An Off-The-Self Pellet Extruder, Aywan Das

Theses and Dissertations

Large Format Additive Manufacturing (LFAM), or Big Area Additive Manufacturing (BAAM), was introduced to resolve the limitations of the low deposition rate, low scalability, and therefore long print times, of traditional 3D printing methods when applied to the manufacturing of large structures and tooling. LFAM can be used to overcome the high conventional tooling costs of large structures. However, even with robotic setups, LFAM still mainly relies on quasi-planar, 2.5D printing strategies. This fails to reap the advantages of multi-axis printing, such as improved adhesion, reduced support material use, and the ability to create complex curved surfaces. In this research, …

Developing A Behavior-Based Measure Of Teacher-Student Relationship Quality, Amanda Lynn Davis

Theses and Dissertations

Students benefit from close, supportive relationships with their teachers. When students feel supported by their teachers, they tend to perform more strongly on social, emotional, behavioral, and academic outcomes compared to peers whose relationships with their teachers are conflictual or strained. Emerging evidence suggests that the quality of these relationships may be improved through interventions that increase teachers’ relationship-building behaviors. Yet, the field lacks a measure that explores teacher-student relationship quality by examining the frequency of the specific relationship-building behaviors that may be subject to intervention. The current study aims to address this problem by developing and pilot testing a …

Associations Between Neurological Correlates Of Reading And Learning Disability Profiles Among Children, Jessica Luedke

Preregistration And Registration As A New Method For Transparency Of External Validation In Artificial Intelligence And Machine Learning Applications To Address Overfitting, Underspecification, And Shortcut Learning, Marilyn Elaine Gartley

Theses and Dissertations

Statistics has been defined as the study of how information should be employed to reflect on and give guidance for action in a practical situation involving uncertainty. The essence of uncertainty is that there is more than one possible outcome, and the actual outcome is unknown in advance; it is indeterminate. The goal of statistical methods is inference: namely, statistical inference—reaching conclusions about populations or deriving scientific insights from data which are collected from a representative sample of that population through providing a mathematical understanding of inference, quantifying the degree of support that data offer for assertions of knowledge, as …

How Organizational Structure And Power Dynamics Impact Decision Making—An Empirical Investigation Of General Manager Turnover In The National Basketball Association, Xiaoan Huang

Applications Of Catalytic Ammonia Chemistry: From Low-Pressure Ammonia Synthesis To The Decomposition Of Tritiated Ammonia As A By-Product Of Magnetically Confined Nuclear Fusion, Jennifer Kules Naglic

Theses and Dissertations

Ammonia is the 2nd most produced chemical in the world with vital importance for its use in fertilizer as the global population has grown in accordance with the industrialization of NH3. While 80% of NH3 produced goes to fertilizer, it has gained attention recently as a hydrogen storage and transportation vessel. Industrially, NH3 is produced at high temperatures and pressures which in turn require high electrical input. Turning to a green NH3 cycle with low temperature and pressure membrane reactors for both NH3 synthesis and decomposition would allow for much lower energy input as well as a renewable energy to …

Interface Between Sensorimotor Dynamics And Trunk-Hip Movement Control: Implications For Movement Assessment In Low Back Pain, John Ryan Gilliam

Theses and Dissertations

Low back pain is the leading cause of activity limitation and work absence and results in billions of dollars in healthcare expenditures. Impaired trunk-hip movement control is associated with the development of back pain and the persistence of symptoms. Theories suggest a causal relationship between altered sensorimotor dynamics, including altered afferent somatosensory information from the periphery and neuroplastic central nervous system adaptations, and impaired trunk-hip movement patterns. We characterized trunk-hip movement patterns and their associated sensorimotor brain dynamics in people with and without chronic low back pain (cLBP). Supine, atop an instrumented system, 48 individuals with cLBP and 37 healthy …
