Queering Latinidad: Latinx Politics Beyond Nativity, Melina Juarez

Political Science ETDs

Much debate surrounds the emergence of the term "Latinx." While some have argued against its usage, others have deeply embraced it as a way of representing the gender diversity found within the Latina/o community. Yet, these arguments do not transcend the boundaries of gender to include other facets of identity subverted within the concept of Latinidad. This project seeks to extend the boundaries of Latinx to include other areas of identity that are inherent parts of being a Latino in the United States, including sexuality, African roots, indigeneity, among others. This dissertation seeks to understand whether our rigid conceptualization of …

Exploration Of The Qualities And Interactions Of Post-Secondary Faculty Identified As Exemplary By Students With Support Services, Joan E. Green

Special Education ETDs

Recent statistics indicate that approximately 11% of undergraduate college students seek out disability support services (National Center for Education Statistics, 20015). The review of research indicated a lack of research regarding faculty in postsecondary education and their knowledge of disabilities and services, experiences of individuals with disabilities, and in particular, experiences and interactions toward students with support services attending postsecondary educational institutions. The purpose of this case study was to explore the classroom experiences of seven faculty nominated by students with support services as exemplary at a four-year public university. The semi-structured interviews focused on the abilities of students with …

Local Government Spending On Public Housing: Factors Of Influence In Metropolitan Areas, Vittoria R. Totaro 2241446

Public Administration ETDs

Rent or mortgage payments make up the largest portion of an American family’s budget. As there is a limited housing stock in metropolitan areas, low-income families struggle to find housing that is both adequate and affordable. Federal housing programs make funding available, but the provision of housing is left to local governments. Through the implementation of bold strategies and initiatives, local governments can help their low-income constituents find permanent housing for themselves and their families.

Public housing in the U.S. is associated with dilapidation, overcrowding, and social disorganization. In the past, housing projects have been shortsighted measures aimed at addressing …

Transgender Murder Memorials: A Call For Intersectionality And Trans Livability, Lazarus Nance Letcher

American Studies ETDs

The number of transgender folks in the United States lost to murder increases every year. These murders have recently gained more recognition, with the memorials moving from trans-run organizations and communities to mainstream LGBTQ groups. Using visual culture and discourse analysis of four transgender murder memorials, I argue there are problematic trends of centering a white and cisgender audience, and lack of acknowledging trans livability. Memorials like Transgender Day of Remembrance take place every year, and though the oldest memorial for trans death in the country and most well known, the event creates a spectacle of violence for cisgender consumption …

Transcranial Direct Current Stimulation (Tdcs) Improves Performance On Spelling And Word Detection Tasks, J. Kevin Wilson

Psychology ETDs

Deficits in written language involving spelling can have negative effects on a person’s education and occupation. Conventional spelling therapy is a time consuming and cost-prohibitive option, if even available, highlighting the need for improved methods for remediation. One possible way to address this need may be through the use of transcranial direct current stimulation (tDCS). This study sought to examine the effects of tDCS on performance during spelling, word detection, and facial recognition tasks. Active or sham tDCS was randomly assigned to typically functioning adults. The anode electrode was placed over Broca’s area (F7 in the 10/20 EEG system) and …

A diversity of public and private initiatives strive to address the human-environment challenges confronting the global coffee industry, including certifications like Fairtrade, direct trade sourcing models, and efforts led by NGOs. Research examines the outcomes of major certification programs and the private initiatives of corporations like Starbucks. Much less is known about the business practices of the small specialty coffee businesses that increasingly advertise sustainable business practices. Yet, their collective business practices likely influence the industry-wide efforts to achieve a sustainable supply chain. This research examines how small specialty coffee roasting and importing companies represent their socially responsible business practices …

The Effect Of Sublingual Testosterone On Ischemic Pain Sensitivity, Chance Strenth

Psychology ETDs

Sex differences in pain have been reported for over a half-century with males having higher pain tolerance and lower pain sensitivity than females. Testosterone, a male hormone, is associated with pain perception in humans. However, as of yet no study has directly manipulated a participants’ testosterone to test for causal relationship between testosterone and pain. A double-blind fully-crossed study was conducted using sublingual administration of 0.5 mg testosterone. Twenty female participants completed two 5-hour sessions over a 3-day period. Participants completed an ischemic pain task, behavioral tasks and self-report measures at baseline and at post-administration to explore the effects of …

Bioinformatics- And Phylogenetics-Guided Approaches To Understanding Sequence-Function Relationships Of Type Ii Polyketide Biosynthetic Gene Clusters, Han Bich Nguyen

Type II polyketides (PK-II) has made up a class of natural products that are structurally diverse and are clinically useful due to their wide-range of bioactivity. The work described in this dissertation focuses on developing approaches to facilitate our understanding of sequence-function relationships of PK-II biosynthetic gene clusters (BGCs). We have systematically summarized the previous characterizations of enzymes involved in the core structure biosynthesis, which have set a foundation for our developments of approaches to discover organisms harboring novel enzymes responsible for novel PK-II molecules. We have successfully developed bioinformatics tools to globally mine the PK-II BGCs in the NCBI …

Prevalence Of Artemisinin Resistance Associated Single Nucleotide Polymorphisms In Kenyan Isolates, Elizabeth M. Glenn

Biology ETDs

Malaria has had an unspeakable toll on human economy and wellbeing. Every year, there are approximately 212 million malaria infections caused by Plasmodium falciparum leading to 429,000 deaths, the vast majority of which occur in sub-Saharan Africa where the parasite is endemic. Decades of widespread use, and probable misuse, of antimalarial drugs has created extraordinary selective pressure on the parasite and made many formerly effective drugs ineffective. Currently, artemisinin and artemisinin derivatives are the most effective treatment available but resistance to dihydroartemisinin (DHA), the active ingredient, is emerging. Continued monitoring for genetic mutations linked with resistance is vital to global …

Factors That Determine Spreading Depolarization Propagation In Brain Slices, Linday Selters

Biomedical Engineering ETDs

In the US alone, more than 750,000 people had a stroke in 2017, more than 1.7 million reported a traumatic brain injury, and more than 9 million suffered from migraines with aura. While all three of these neurological conditions have vastly different causes and possible outcomes they all have a common phenomenon occurring within the brain. A wave that slowly propagates through grey matter, hitting neurons with a large burst of energy, opening them up to a flood of ions and silencing them for an extended period of time. These waves are known as spreading depolarizations (SD). Within well-nourished tissue, …

Evaluating The Aryl Hydrocarbon Receptor As A Target For Pharmacologic Activity Of Repurposed Drugs, Teofilo Borunda Duque

Pharmaceutical Sciences ETDs

The discovery of new pharmacologic targets is important for the advancement of pharmacotherapy and identification of new indications for current drugs. The aryl hydrocarbon receptor (AHR) is a physiologic sensor of both chemical environmental pollutants and ligands of natural origin. Given the broad spectrum of ligands that activate the AHR and its relationship with toxicology, the AHR is not thought to be a traditional target for pharmacotherapy. However, multiple studies have shown potential for the AHR as a novel pharmacologic target Therefore, identifying less toxic agents that modulate the AHR may elucidate mechanisms for pharmacological targeting of the AHR. The …

Chlorine Stain And The Oral Cavity, Alexandra B. Moore

Dental Hygiene ETDs

Swimming is known worldwide as one of the healthiest, low-impact forms of exercise and for the subsequent promotion of a strong body, heart, and mind. However, many swimmers and non-swimmers do not realize that swimming in a pool can have a negative effect on the oral cavity. Several studies have suggested that pool chlorination is responsible for dental erosion, calculus formation, and stain in competitive and recreational swimmers, and this phenomenon is known as ‘swimmer’s mouth.’ A pilot experimental research study was conducted that evaluated the prevalence of chlorine stain in the oral cavity of twenty-one female swimmers from the …

Many green sea turtle populations are slowly recuperating from a recent severe decline due to anthropogenic factors including human consumption and mortality related to the fishing industry. Despite being charismatic animals that have been extensively studied, there is still a limited understanding of their feeding strategies and diet plasticity. This research explores the use of hydrogen isotopes in marine ecosystems to better understand green sea turtle ecology. This study is presented in two chapters: I first examined the trophic discrimination factor (D²H_NET) for hydrogen isotope (d²H) as a tool to correct hydrogen isotope data …

An Investigation Of The Effects Of The Second Pyrolysis On The Chemistry, Morphology, And Performance Of Iron-Nicarbazin Catalysts, Elizabeth B. Weiler

Chemical and Biological Engineering ETDs

Proton exchange membrane fuel cells offer a cost-effective, environmentally friendly, and sustainable alternative to petroleum-based power sources to the transportation sector. However, slow electrochemical reactions at the cathode of these fuel cell prevent the technology from being competitive. Iron-nitrogen-carbon based catalysts have emerged as a viable answer to this problem, yet further progress is needed to improve their performance beyond that of current state-of-the-art platinum-based catalysts, which are economically and geopolitically impractical to be a final solution. Currently, a two-step high temperature pyrolysis method has proven a promising way to synthesize iron-nitrogen-carbon catalysts for optimized performance, but there is a …

Water Quality Assessment In The Santa Fe River: Tracking Pollution Sources Via Quantitative Polymerase Chain Reaction Analysis, Hayley Aurora Hajic

Geography ETDs

Microbial contamination affects many water bodies in the United States and pathogens associated with contamination pose a threat to human health. While the nation’s lakes, streams and rivers have been monitored for decades, many still do not meet the requirements of the 1972 Clean Water Act. Due to the number of pathogens that occur in water bodies, it is not feasible to directly monitor all of them. Instead of testing for a plethora of pathogens, it is standard practice for water divisions to monitor fecal indicator bacteria (FIB) as a proxy to determine water quality. There are significant flaws, however, …

The Heart Of K'É: Transforming Diné Special Education And Unsettling The Colonial Logics Of Disability, Sandra Yellowhorse

American Studies ETDs

This paper takes up the roles of ideology and spatiality as they impact Diné students and learners in understanding conceptions of normativity, neuro-diversity and bodily variance. I am concerned with how the movement and creation of Indigenous schools and their praxis still maintain and often times produce settler colonial ideologies of being, personhood, difference and ability. I illustrate the challenges that Diné planners and educators face in entrenching cultural knowledge and language into their educational initiatives, while some of the problematic manifestations and expressions of normativity present themselves through state polices, federal law and mainstream curriculum.

I focus on the …

Development Of A Positron-Emitting Surrogate Microsphere For Image-Based Dosimetry In Yttrium-90 Radioembolization Therapy, Gregory D. Chambers

Nuclear Engineering ETDs

Radioembolization of liver tumors using yttrium-90 (Y-90) labeled microspheres is a proven method of treatment. The primary decay mode of Y-90 is beta-minus decay. The electrons produced during decay deliver a cytotoxic radiation dose in a localized volume. The radiation dose is sufficient to kill tumor cells yet spare the normal liver. The Y-90 microspheres are delivered via a catheter that has been placed in an artery that supplies blood to the tumor. Microspheres are injected and the blood distributes the microspheres. The current practice involves two separate procedures. The first procedure is an assessment of the vasculature of the …

Patient Specific Radiation Doses From Projection Radiography Images: Improving The Accuracy Of Low Dose Radiation Calculations, Daniel J. Sandoval

Nuclear Engineering ETDs

Due to an increase in regulatory scrutiny and medical facility accreditation requirements to monitor patient radiation dose from diagnostic imaging procedures, there is a growing necessity to determine and record accurate patient radiation dose from diagnostic medical imaging procedures. Current methods of patient dosimetry in diagnostic imaging are both extremely difficult and time consuming, require large computing resources (such as Monte Carlo computations), or lack accuracy due to using data based on homogeneous materials and “standard-man sized” anthropomorphic models.

This dissertation provides an algorithm that calculates a more accurate dose using patient-specific projection radiographic images. The algorithm includes measurements acquired …

The purpose of this study was to quantify Minnesota dentists’ attitudes regarding the utilization of dental therapists in that state. A survey was constructed that queried dentists’ opinion on dental therapists performing irreversible procedures and dental therapists alleviating the disparity in access to dental care. A stratified random sample of 1,000 dentists were invited to participate in …

An Exploration Of The Optical Detection Of Ionizing Radiation Utilizing Modern Optics Technology, Sean D. Fournier, Adam Hecht, Cassiano De Oliveira, Jeffrey B. Martin, Richard K. Harrison, Charles Potter

Nuclear Engineering ETDs

Modern ultraviolet (UV) cameras, when combined with UV-transmitting lenses/filter arrangements, can be used to detect radiation dose in air. Ionizing radiation excites nitrogen molecules in ambient air, the resulting decay includes weak emission of ultraviolet photons. Previous work has proven this phenomenon is detectable using highly-sensitive electronically cooled cameras traditionally used in astronomy for low-background imaging. While the ability to detect the presence of radiation (i.e. qualitative measurement) has been demonstrated at Sandia National Laboratories, there are several challenges in correlating images to known dose-fields (quantitative measurement). These challenges include: a low signal to background ratio, interferences due to electronic …

Moderate Prenatal Alcohol Exposure Impairs Performance In An Object-Place-Paired-Associate Task, Lilliana May Sanchez

Psychology ETDs

Memory impairments, including spatial and object processing, are often observed in individuals with Fetal Alcohol Spectrum Disorder. Much attention has been directed towards the hippocampus, which displays significant alterations after moderate prenatal alcohol exposure (PAE). In the present study, we tested a moderate PAE rat model in an object-place-paired-associate (OPPA) task, previously shown to require hippocampal processing. The OPPA task was composed of training rats to discriminate between an identical pair of objects presented in 180° opposite arms of a radial arm maze. Animals were given a total of 10 trials per day over 14 consecutive days of training and …
