WHEN WORLDS COLLIDE

Cheryl Kwok
The relationship experiences of bisexual-identifying men of color have been neglected in psychological studies of race, gender, and sexuality. Few studies, if any, have examined the relationship experiences of Asian bisexual men, even though this population’s multiple marginalized and stigmatized social identities increase their health risks (Bryant-Davis, 2007; Carter, 2007; Ching et al., 2018). Bisexuality is commonly defined by an individual’s intimate partner attraction and/or behavior (e.g., Swan & Habibi, 2018), making relationship experiences fundamental...

A THEORETICAL STUDY ON INTEGRATION AND OPTIMIZATION OF GAS TURBINE PROBLEMS WITH SOLAR ENERGY SYSTEM

Ahmad Abubaker
Gas Turbine (GT) power plants suffer from sensitivity to ambient-air temperatures, high fuel consumption, and a high amount of waste heat dumped into the ambient. Various solutions were proposed to solve these drawbacks, which could simultaneously solve at most two problems, usually at the expense of the third. For instance, inlet-air cooling can reduce ambient-air temperatures but will result in increased fuel consumption. However, in this work, a novel cascaded system was integrated into a...

Combinatorial Invariants of Rational Polytopes

Andrés Vindas Meléndez
The first part of this dissertation deals with the equivariant Ehrhart theory of the permutahedron. As a starting point to determining the equivariant Ehrhart theory of the permutahedron, Ardila, Schindler, and I obtain a volume formula for the rational polytopes that are fixed by acting on the permutahedron by a permutation, which generalizes a result of Stanley’s for the volume for the standard permutahedron. Building from the aforementioned work, Ardila, Supina, and I determine the...

THE USE OF MECHANOTHERAPY TO PROMOTE THE RECOVERY FROM DISUSE ATROPHY IN AGING RAT SKELETAL MUSCLE

Zachary Hettinger
The combination of age and disuse-related skeletal muscle atrophy predisposes older adults to reduced mobility, loss of independence, and poor quality of life. Poor health outcomes resulting from periods of disuse in older adults are exacerbated by an inability to fully recover, ultimately accelerating geriatric populations towards further functional decline. Aged-related changes to skeletal muscle viscoelastic properties, specifically of muscle extracellular matrix (ECM) stiffness, may not only impact how muscle responds during recovery, but also...

DELINEATING THE ROLE OF FATTY ACID METABOLISM TO IMPROVE THERAPEUTIC STRATEGIES FOR COLORECTAL CANCER

James Drury
Colorectal cancer (CRC) remains a leading cause of cancer-related deaths in the world, comprising over 1 million new cases each year and over 500,000 deaths. CRC, when detected at an early stage of disease development, can be effectively treated, with a 5-year survival rate of over 90%. Such standard treatments include surgical resection of the primary tumor in combination with adjuvant chemotherapy. However, even with advancements in surgical procedures and chemotherapeutic targets, when CRC progresses...

Novel Mammalian Models for Understanding and Treating Spinal Cord Injury

Michael Orr
Spinal cord injury (SCI) is devastating and often leaves the injured individual with persistent dysfunction. The injury persists because humans have poor wound repair and there are no pharmacologic treatments to induce wound repair after SCI. The continued efforts to discover therapeutic targets and develop treatments heavily relies on animal models. The purpose of this project is to develop and study novel mammalian models of SCI to provide insights for the development and effective implementation...

Genetic Mouse Models of Liver Disease

Courtney Turpin
The liver is the largest internal organ in mammals and responsible for carrying out various processes, including lipid and carbohydrate metabolism, detoxification of chemicals, and production of serum proteins. Liver damage, which can be caused by a variety of agents including viral infection, environmental toxins, alcohol and excessive dietary fats, can cause dysregulation of these critical functions, leading to worsening liver pathophysiology and impacting health. However, the liver has the remarkable ability to regenerate when...

LOCALIZATION OF STATIONARY SOURCE OF FLOOR VIBRATION USING THE STEERED RESPONSE POWER METHOD

Mohammad Royvaran
If the generated vibration in a building exceeds the acceptable limit design for a floor system, it is necessary to identify the source of vibration, a process known as localization. The objective of this study is the localization of stationary vibration sources, and the approach used is the steered response power (SRP) method. This method has already been shown to work well for wireless and acoustical applications to locate transmitter and sound sources, respectively. To...

EFFECTIVE FIELD THEORY APPLICATIONS: FROM DARK MATTER TO NEUTRINO NUCLEON SCATTERING

Qing Chen
Weakly-interacting-massive-particles (WIMPs) are a large class of viable dark matter candidates. We compute cross sections for electroweak-doublet WIMPs scattering on atomic nuclei, at leading and subleading order using heavy WIMP effective field theory. Neutrino-nucleon charged current elastic scattering is an important process in the detectors of long baseline accelerator neutrino oscillation experiments. We compute QED radiative corrections to this process employing soft-collinear effective field theory.

CRITICAL AUDIT MATTERS REQUIREMENTS AND AUDITOR REPORTING BEHAVIOR

Valbona Sulcaj
In this study, I examine two research questions related to the reporting requirements of critical audit matters (CAMs) introduced in the Audit Standard (AS) 3101. First, I examine whether auditor’s perceived litigation risk and client’s financial reporting quality are associated with the number and textual attributes of CAMs. Second, I examine whether the number and textual attributes of CAMs are associated with audit effort and costs. Consistent with the litigation hypothesis (Skinner, 1994), I find...

The Role of Live Conifer Fuels in Crown Fires Spread

Adnan Darwish Ahmad
Live foliage for some tree and shrub species can support flaming fire spread at much higher moisture content than dead fuel materials. However, the role of live fuels in forest fires has been controversial in the past decades. Although ignition and spread statistical data for live and dead fuels exist in the literature, a clear understanding of the fundamental difference in the burning behavior is missing. To illuminate the role of live fuel on forest...

DEVELOPMENT OF TOOLS FOR ATOM-LEVEL INTERPRETATION OF STABLE ISOTOPE-RESOLVED METABOLOMICS DATASETS

Huan Jin
Metabolomics is the global study of small molecules in living systems under a given state, merging as a new ‘omics’ study in systems biology. It has shown great promise in elucidating biological mechanism in various areas. Many diseases, especially cancers, are closely linked to reprogrammed metabolism. As the end point of biological processes, metabolic profiles are more representative of the biological phenotype compared to genomic or proteomic profiles. Therefore, characterizing metabolic phenotype of various diseases...

BUILDING COMMUNICATION, COLLABORATION, AND SELF-EFFICACY AMONG ELEMENTARY SCHOOL COUNSELORS THROUGH COMMUNITIES OF PRACTICE

Garrett Rimey
There are few life-changing experiences like transitioning from elementary school to middles school. A new setting, new peers, new teachers, and new structures have been shown to elicit a myriad of emotions from students as they transition into middle school. A student’s academic record, accommodations, and other pertinent academic information follow a student into middle school; however, their social and emotional portfolio does not. Research has shown that students who are negatively impacted the most...

HÍBRIDOS, MONSTRUOS, CÍBORGS Y POSTHUMANOS

Naiara Porras Rentero
Rosi Braidotti warns us in her book Lo posthumano (2013) that “when the word difference implies inferiority, the connotation can be both dangerous and harmful for those marked as the other” (12). Since Michel Foucault first began his analysis of biopolitics, there have been many thinkers who have theorized how heteropatriarchal roles demand conformity at the risk of self-alienation and loss of identity. The theatrics demanded by an externally imposed social order can tax personal...

A NOVEL ROLE FOR NEUROTENSIN IN REGULATION OF STEM CELL FUNCTION IN THE SMALL INTESTINE

Stephanie Rock
Neurotensin (NT) is a nutrient-regulated gut hormone that plays important roles in lipid absorption, obesity, metabolic disorders, and normal and neoplastic growth in the intestine. In this study, we 1) elucidate the mechanisms regulating NT release from endocrine cells, 2) examine the role of NT on proliferation and stem cell function in the small intestine and 3) define the effects of NT on colorectal cancer stem cells. We report that NT release from endocrine cells...
