Synthesis Of Chemical Fuels And Feedstocks From Co2 For Extraterrestrial Applications, Samuel Keith Conlin

Graduate Theses and Dissertations

The reduction of CO₂ into products for either the storage of renewable electricity or to act as a source of renewable feedstock for industry, is not economically feasible given the current costs of renewable energy. Significant amounts of work have gone into attempting to optimize both electrochemical and nonthermal plasma-based CO₂ reduction systems in an attempt to reduce side reactions and improve energy efficiency in order to meet cost feasibility targets. These techniques can also be adapted for In-Situ Resource Utilization (ISRU) contexts, which are far less sensitive to the cost of renewable energy yet have more strenuous …

Multimodal Spectroscopy To Study Tumor Microenvironmental Changes In Vivo, April Mordi

Graduate Theses and Dissertations

Every year there are millions of new cancer diagnoses and deaths worldwide. While great strides have been made in technologies and drugs for cancer treatment, there is still a need to understand tumor response to therapy as many patients still endure treatment failure after completing their treatment regimen. Current clinical imaging techniques for detecting response to therapy are utilized weeks to months after the course of treatment, and present limitations to measuring response during treatment. Optical spectroscopy techniques can help meet this need to determine the response of tumors to treatment as it allows for near real-time in vivo characterization …

Exploring The Interplay Between Testosterone Levels And Gender Role Attitudes, Arial Bloshinsky

Graduate Theses and Dissertations

Traditional gender role attitudes align men with resource management and women with nurturing. The Challenge Hypothesis proposes that resource management is associated with higher testosterone levels, whereas nurturing is associated with lower testosterone levels. Therefore, traditional gender role attitudes may be associated with people’s testosterone levels. Furthermore, during the transition to parenthood, traditional gender role attitudes may become particularly salient, as shifting biological, social, and cultural roles during this transition make these attitudes an integral part of daily life. In this longitudinal study of expectant couples, participants completed a baseline survey and baseline session, during which they completed measures and …

Online Self-Directed Learning About Covid By Custodial Fathers In The U.S., Susan Bradley

Graduate Theses and Dissertations

The COVID pandemic was a time of unprecedented need for self-directed learning due to a conflagration of factors. These included the rapid global spread of the virus, leading to over 1.8 million deaths worldwide in 2020 alone according to the World Health Organization.

Simultaneously, due to COVID’s strain on the healthcare system, people were urged to refrain from visiting their doctors …

Black Lives Still Matter: Freedom Schools As An Embodiment Of Critical Literacy Through Reflection And Action, Elena M. Venegas, Lakia M. Scott

Bilingual and Literacy Studies Faculty Publications

The continuation of racial inequities in the United States has ignited the recent Black Lives Matter Movement, a protest of police brutality and gun violence. Black lives matter in public school classrooms, too—where students of color face barriers to equitable educational experiences. The Children's Defense Fund Freedom School program is a major component in developing critical literacy skills through critique, inquiry, and transformation through social justice and action. Critical literacy is enacted through identity—mainly as difference, self, consciousness, narrative, and positionality. Historical and contemporary relevance of Freedom Schools connects to the urgency of the Black Lives Matter Movement.

The Role Of Epigenetic Aberrations In The Cold Tumor Phenotype And Inflammatory Signaling In High-Risk Neuroblastoma, Pamela Morgan Watson

Alternative Theses and Dissertations (AETDs)

Neuroblastoma (NB) is a highly aggressive, heterogeneous disease that arises from the sympathetic nervous system (SNS) and originates from neural crest cells (NCCs) (1). NB is the most common extracranial cancer in pediatric accounts for 15% of pediatric cancer deaths (2). This high mortality rate is the result of the metastatic, immune evasive, and treatment resistant characteristics of the disease (3). It has been proposed that NB arises from blocks in differentiation during development, resulting in a mixture of two distinct cell types within the tumor: mesenchymal and adrenergic (Figure 1.1) (4,5). The adrenergic cell type is more differentiated, and …

Generating A Reflexive Ai-Assisted Workflow For Academic Writing, Corey W. Johnson, Trena M. Paulus

The Qualitative Report

Digital research workflows are study designs that intentionally consider the use of technology in meaningful and reflexive ways. While most scholars use digital tools and spaces in their research process, doing so has consequences that are infrequently considered in an intentional way. Especially in this age of generative AI, technology integration into research studies will have an even greater impact and consequences on study outcomes. This paper documents one digital research workflow, the academic writing process, to demonstrate how inviting generative AI to be a writing partner can be done in a reflexive manner. Drawing on Paulus and Lester’s (2023) …

Determinants Of Child Care Subsidy Policies In The American States: A Mixed-Method Investigation In The Era Of Covid-19, Hailey Heinz

Political Science ETDs

This mixed-method dissertation investigates policy variation in states’ administration of the federal child care subsidy program (CCDF). The quantitative chapters draw on a 50-state, ten-year dataset to examine associations between state characteristics and CCDF policy outcomes. These analyses conclude that state-level drivers of CCDF policy are distinct from drivers identified in the cash welfare literature, and that drivers vary across dimensions of CCDF policy. The qualitative chapters report results from a comparative case study examining CCDF policy in New Mexico and Nevada from 2010 to 2022. These analyses conclude that the departmental placement of the CCDF program within state government …

Identity And Inequality Misperceptions, Demographic Determinants And Efficacy Of Corrective Measures, K. Peren Arin, Deni Mazrekaj, Marcel Thum, Juan A. Lacomba, Francisco Lagos

All Works

By conducting two waves of large-scale surveys in the United Kingdom and Germany, we investigate the determinants of identity and inequality misperceptions. We first show that people substantially overestimate the share of immigrants, Muslims, people under the poverty line, and the income share of the richest. Moreover, women, lower-income, and lower-educated respondents generally have higher misperceptions. Only income share misperceptions are associated more with people who place themselves on the left of the political spectrum. In contrast, the other three misperceptions are more prevalent among those who place themselves to the right. We then attempt to correct misperceptions by conducting …

Using Nano-Ities For Detection Of Metal Ions In Complex Aqueous Solutions, Mohammed Muzammil Nishar Ahmed

Theses and Dissertations

Recent urbanization has induced a rapid increase in heavy metal exposure to humans. The exploitation of heavy metals for economic gains coupled with poor and economically infeasible recycling methods have led to poor management of heavy metal wastes, which has opened up several pathways for heavy metals to enter the human body. Such heavy metals target many vital organs, but the early symptoms are common and difficult to diagnose. Severe symptoms appear in later stages and are very expensive to treat and the damage caused to the health are not typically reversable in such later stages. To counter this issue, …

Demonstrating Feasibility Of Ultrasound-Sensitive Microbubbles Delivery To Treat Disruptions In The Blood Brain Barrier Endothelium, Rubens Jourdain

Theses and Dissertations

Vascular cognitive impairment and dementia (VCID) is one of the main causes of dementia. VCID is caused by age and other genetic factors that lead to disruptions in the blood brain barrier (BBB) and allow blood components to enter the brain. The currently available treatments of VCID include opening the BBB with high-frequency-ultrasound to deliver drugs to the brain. However, this only treats the already developed disease. Consequently, we developed a new drug delivery system whose goal is to restore the brain capillary endothelial cells (BCEC) lining the blood vessel. The objective of this study was to demonstrate the feasibility …

Investigation Of Reproductive Inhibition During Chronic Heat Stress In C. Elegans, Macy Makenna Nielander

Theses and Dissertations

Nearly all organisms experience heterogeneity in environmental conditions that can negatively impact fitness. A common adaptive strategy to reduce the impact of this stress is called facultative diapause, where development and reproduction are temporarily arrested to promote survival. Facultative diapause is characterized by three major criteria, the arrest must be (i) induced by an unfavorable environmental condition, (ii) reversible, and (iii) driven by genetically regulated mechanisms. The aim of this thesis was to determine whether chronic heat-induced inhibition of egg laying in Caenorhabditis elegans represents a novel form of facultative diapause. It was found that the inhibition of egg-laying is …

Faculty, Staff and Student Publications

Metabolic abnormalities are an important feature of tumours. The glutamine-arginine-proline axis is an important node of cancer metabolism and plays a major role in amino acid metabolism. This axis also acts as a scaffold for the synthesis of other nonessential amino acids and essential metabolites. In this paper, we briefly review (1) the glutamine addiction exhibited by tumour cells with accelerated glutamine transport and metabolism; (2) the methods regulating extracellular glutamine entry, intracellular glutamine synthesis and the fate of intracellular glutamine; (3) the glutamine, proline and arginine metabolic pathways and their interaction; and (4) the research progress in tumour therapy …

Take A Ballot: Can Transnational Theatre Foster Political Efficacy In Women Of Color?, Breanna Marie Bailey

Undergraduate Honors Theses

This research examines whether transnational theatre fosters political efficacy in women of color. Research shows the history of disenfranchisement of women of color; even today, upper-class, white males have the greatest access to civic resources– including access to theatre–which ignite their political efficacy in the United States. The gap in research surrounds how, and if, transnational theatre can affect women of color’s political efficacy. By analyzing theatre’s role in engaging political efficacy, I offer an avenue to build a more equitable and democratic society. Using a case study analysis of two female playwrights from opposite sides of the U.S. border–Sor …

Preparing Educators To Effectively Engage With Postsecondary Stem Students With Autism, Luzconsuelo Gavaldon

Open Access Theses & Dissertations

Autism spectrum disorder (ASD) is a lifetime mental disability (Boucher, 2009). Because the brains of people with autism work differently than their non-neurodiverse peers (Kuzminskaite et al., 2020), they tend to respond to external stimuli in a hypo- or hyper-sensory fashion. One of the primary considerations that must be accounted for when working with individuals with autism is that the brains of these persons are each neurologically distinct. In other words, there is no "one-size-fits-all" means by which individuals with ASD learn and develop and, consequently, no single way to therefore engage with said individuals (Anderson & Butt, 2017; Kuzminski …

Myofibroblast Targeted Liposomes For The Treatment Of Skin Fibrosis, Elfa Beaven

Open Access Theses & Dissertations

Continuous overactivation of myofibroblasts leads to excessive deposition of profibrotic proteins, which in turn causes tissue stiffness and, ultimately, organ failure. One of those proteins, Cadherin-11 (CDH11), is reported to be overexpressed in the tissue of fibrotic skin, specifically on myofibroblasts. Similarly, chronic inflammation drives fibrosis progression in autoimmune-related illnesses like systemic sclerosis (SSc). Therefore, it is hypothesized that CDH11 could be a target for cell-specific delivery of antifibrotic therapies to fibrotic skin tissue. Here, a CDH11 peptide conjugated liposome loaded with Tofacitinib, a JAK inhibitor, was developed to understand the potential of targeted therapies to treat skin fibrosis. The …

Not Plato's Closet: The Dialectic Of Embodied Counterstory Through Fashion On The Us/Mexico Border, Brita M. Arrington

Open Access Theses & Dissertations

This dissertation is best understood as a journey about identity that took place over more than eight years. The journey was an exploration that began in one frame of mind and ended in a very different place. I fully anticipated this research to reflect the racial tensions surrounding my participants who are predominantly Latine students at UTEP, a "Hispanic serving" institution on the US/Mexico border, but we ended up a place more deeply personal to them. From a sample of 2000 FYC students and their instructors, 65 participants engaged in taking a survey about their dress practices, and 4 of …
