cycloaddition reactions, that is utilized in biorthogonal chemistry. This metal free version The strain promoted azide-alkyne cycloaddition (SPAAC) reaction is one of the popular 1,3-dipolar of click reaction offers advantage over copper catalyzed click reaction. Since it eliminates the use of copper that is toxic to cells, it is considered favorable for biocompatible reaction. Due to the increased reactivity with dipoles without the use of metal catalyst, cycloalkynes, in particular cyclooctynes, have been employed as the biorthogonal reagent in biorthogonal chemical reaction for the study of a biological processes in vivo. The …

News Media Framing Of Disabilities In Ghana: Journalistic Practices Amidst Advocacy Calls For Change, Pamela Ofori Boateng

Communication ETDs

The study contributes to expanding scholarly research on media portrayals of people with disabilities in Ghana. Drawing on theories of framing, ableism, and intersectionality, I analyzed news stories published in Graphic.com.gh. in 2021 and 2022 to explore how the editorial practices framed people with disabilities and how framing patterns revealed change and continuity in representation. The findings affirmed a shift to using more diverse and appropriate language to represent people with disabilities more fairly and accurately; the categorization of most of the disability stories under “General News,” which suggests the significance attached to disability related stories; and the …

Queer Crises: Movements From Queerness And Feelings Of White Religion In The United States, Austin Williams Miller

Communication ETDs

Anchored by contemporary crises surrounding queer and trans people in the United States, I employ movements from queerness within an affective queer phenomenological framework to understand how arrangements of “white religion” (Schaefer, 2015, p. 63), a process whereby U.S. American Christian forms escape ideology into religious affective economies in the United States, relegate queer people “to the background… to sustain a certain direction” (Ahmed, 2006, p. 31). I assemble a queer rhetorical context analyzing white religious space in documentary film, secular sexual regulation through contemporary U.S. legal contexts around marriage, and settler colonial Christian nationalist political imaginations to critique how …

“The Wild Ones: Violence, Vengeance, And Sensationalism In The Borderlands”, Leah Candolin Cook

History ETDs

“The Wild Ones: Violence, Vengeance, and Sensationalism in the Borderlands” provides a microhistory of an incident that took place in the Arizona-Sonora border region in the late 1920s and early 1930s. The event involved the kidnapping of a Mexican boy by an Apache band living in the Sierra Madre Occidental, the American volunteer expedition to recover him, and the media frenzy that ensued. Untangling the multifaceted motivations behind the “Fimbres affair,” as the situation came to be known, and situating them within a longer history of sensationalizing and exploiting cross-cultural violence in the borderlands is one purpose of this study. …

The (Im)Mobility Of Being: The Anti-Black And Colonial Roots Of Contemporary Policing, Korey Tillman

Sociology ETDs

Popular debates over policing often revolve around spectacular forms of police violence that grab national media attention. In this study, I examine the everydayness of contemporary U.S. policing and the antiblack and colonial roots that sustains its many forms. Drawing on three years of ethnographic fieldwork with a grassroots abolitionist organization and homeless service provider, and 23 interviews with Black adults across the U.S., I show how mundane policing serves as sites of racialization where the category of human is contested. I offer stops as an analytic to observe how these mundane forms of policing occur in places such as …

Disrupting Whiteness In Education Organizations: Community Testimonios Of Strategy, Resistance, And Perseverance In Educational Justice Organizing, Florence E. Castillo

Sociology ETDs

Through this project, I utilize multiple approaches to disrupt whiteness. I make a case for centering Indigenous and non-Western methods, such as testimonio in sociological studies, to disrupt the academic whiteness of knowledge creation and validation. Whiteness itself is amorphous and looks different depending on circumstances, location, who holds power, and context (Hughey 2016). Utilizing a theory of racialized organizations, I shed light on how whiteness is normalized in education institutions through race-neutral, everyday actions (Ray 2019). This further disrupts whiteness by rendering it visible. Finally, I highlight the different modes of resistance that educational activists use to disrupt whiteness. …

Genomic Analyses In Cornelia De Lange Syndrome And Related Diagnoses: Novel Candidate Genes, Genotype-Phenotype Correlations And Common Mechanisms, Maninder Kaur, Justin Blair, Batsal Devkota, Sierra Fortunato, Dinah Clark, Audrey Lawrence, Jiwoo Kim, Wonwook Do, Benjamin Semeo, Olivia Katz, Devanshi Mehta, Nobuko Yamamoto, Emma Schindler, Zayd Al Rawi, Nina Wallace, Jonathan J Wilde, Jennifer Mccallum, Jinglan Liu, Dongbin Xu, Marie Jackson, Stefan Rentas, Ahmad Abou Tayoun, Zhang Zhe, Omar Abdul-Rahman, Bill Allen, Moris A Angula, Kwame Anyane-Yeboa, Jesús Argente, Pamela H Arn, Linlea Armstrong, Lina Basel-Salmon, Gareth Baynam, Lynne M Bird, Daniel Bruegger, Gaik-Siew Ch'ng, David Chitayat, Robin Clark, Gerald F Cox, Usha Dave, Elfrede Debaere, Michael Field, John M Graham, Karen W Gripp, Robert Greenstein, Neerja Gupta, Randy Heidenreich, Jodi Hoffman, Robert J Hopkin, Kenneth L Jones, Marilyn C Jones, Ariana Kariminejad, Jillene Kogan, Baiba Lace, Julian Leroy, Sally Ann Lynch, Marie Mcdonald, Kirsten Meagher, Nancy Mendelsohn, Ieva Micule, John Moeschler, Sheela Nampoothiri, Kaoru Ohashi, Cynthia M Powell, Subhadra Ramanathan, Salmo Raskin, Elizabeth Roeder, Marlene Rio, Alan F Rope, Karan Sangha, Angela E Scheuerle, Adele Schneider, Stavit Shalev, Victoria Siu, Rosemarie Smith, Cathy Stevens, Tinatin Tkemaladze, John Toimie, Helga Toriello, Anne Turner, Patricia G Wheeler, Susan M White, Terri Young, Kathleen M Loomes, Mary Pipan, Ann Tokay Harrington, Elaine Zackai, Ramakrishnan Rajagopalan, Laura Conlin, Matthew A Deardorff, Deborah Mceldrew, Juan Pie, Feliciano Ramos, Antonio Musio, Antonie D Kline, Kosuke Izumi, Sarah E Raible, Ian D Krantz

Pediatrics Research and Scholarship

Cornelia de Lange Syndrome (CdLS) is a rare, dominantly inherited multisystem developmental disorder characterized by highly variable manifestations of growth and developmental delays, upper limb involvement, hypertrichosis, cardiac, gastrointestinal, craniofacial, and other systemic features. Pathogenic variants in genes encoding cohesin complex structural subunits and regulatory proteins (NIPBL, SMC1A, SMC3, HDAC8, and RAD21) are the major pathogenic contributors to CdLS. Heterozygous or hemizygous variants in the genes encoding these five proteins have been found to be contributory to CdLS, with variants in NIPBL accounting for the majority (>60%) of cases, and the only gene identified to date that results in …

Slavery And Architecture Across The Mediterranean, John Behnken

History ETDs

Enslaved people as architectural material, found in the cultural examples of the Great Mosque of Cordoba and the Hagia Sophia, provide a lens from which scholars can re-envision the historical narrative. The scholarship surrounding the development and transition of the Great Mosque of Cordoba from a mosque to a church, elicits new research into what medieval people thought about race, race-making, and cultural ownership. The conceptions of race are evident through the medieval paradigms of enslavement. Who could and could not become enslaved establish social, cultural, and phenotypic classifications which in turn become race. The work of scholars such as …

Resistance Narratives: Storytelling Of Transnational Insurgencies In 1960-70s Us And Mexico, Tania Libertad Balderas

English Language and Literature ETDs

Resistance Narratives: Storytelling of Transnational Insurgencies in 1960-70s US and Mexico emphasizes how the narratives from the Mexican Insurgency, the American Indian Movement (AIM), and the leftist faction of the Chicana/o Movement in the 1960s and 1970s articulate intersecting notions of resistance, liberation, and transnational solidarity. The comparative analysis of the testimonial novel Las mujeres del alba (2019) by Chihuahuan novelist Carlos Montemayor, the autobiographies Lakota Woman (1991) and Ohitika Woman (1993) by Sičháŋǧu Lakȟóta writer and AIM militant Mary Brave Bird (formerly Crow Dog), and the memoirs and plays by the San Diego-based group Teatro de las Chicanas, collected …

Digitally Rural: Identifying How Technological Inequity Impacts Rural Students In First-Year Writing Courses, Jo Anna M. Nevada

English Language and Literature ETDs

To teach composition in this era means to engage students with technology; it is all but an unspoken requirement at the majority of universities. This dissertation theorizes, however, that the imbricated use of technology in first-year writing (FYW) classrooms places rural students at an inherent disadvantage, with issues of inadequate technological proficiency and inconsistent access causing a substantial learning disparity between this student population and their urban peers. Through mixed-methods data analysis of student survey responses and final FYW course portfolios, this study reveals that the expectation of technological access and presumption of digital literacy is detrimental to rural student …

Miniature, Submersible Electromagnetic Pumps Of Molten Lead And Sodium For Gen-Iv Nuclear Reactors Development, Ragai M. Altamimi

Nuclear Engineering ETDs

Heavy metals and alkali Liquid Metals are suitable coolants for Generation IV terrestrial nuclear reactors for operating at elevated temperatures for achieving plant thermal efficiency more than 40% and the thermochemical generation of hydrogen fuel. In addition, the low vapor pressure of these liquids eliminates the need for a pressure vessel and instead operates slightly below ambient pressure. A primary issue with the uses of these coolants is their compatibility with nuclear fuel, cladding and core structure materials at elevated temperatures more than 500oC. Therefore, in pile and out-of-pile test loops have been constructed or being considered for quantifying the …

Ayllus And Haciendas: Social Reproduction Of Community And Reciprocity In Nineteenth Century Ecuador, Laura Powell

History ETDs

This dissertation argues that indigenous peons of nineteenth-century Ecuador maintained ayllu practices of community and reciprocity through the reconfiguration of kinships networks and the reinterpretation of reciprocity within the context of the hacienda system. This argument challenges prevalent beliefs that indigenous networks of kinship and reciprocity largely dissolved with the rise of the hacienda system and the oppressive exploitation of the institution of debt peonage known as concertaje. However, a close reading of the hacienda records shows that, first, indigenous peons used their ability to accrue debt in order to build and maintain communities of both real and fictive kinship …

The Municipal Acequias Of San Fernando De Béxar: A Working Paper, José A. Rivera Ph.D

Faculty Publications

Of the seven acequia irrigation systems constructed during the height of San Antonio’s Spanish colonial period, five were built for the benefit of the Franciscan missions and their indigenous residents: San Antonio de Valero, Nuestra Señora de la Purísima Concepción de Acuña, San José y San Miguel de Aguayo, San Juan Capistrano, and San Francisco de la Espada. In addition to the five mission acequias, other diversions from the Río de San Antonio and San Pedro Creek were constructed for civilian use within the municipality of San Fernando de Béxar, founded in 1731, now San Antonio: the San Pedro Acequia …

The Water Mills Of The Historic Río Arriba In Northcentral New Mexico, 1598-1975, José A. Rivera Ph.D, Thomas F. Glick Ph.D

Faculty Publications

The water mills of New Mexico played a major role in the agricultural economy of the Río Arriba for centuries following the introduction of wheat from the Old World to the Americas. Wheat, in its ground form as flour, was a staple during the Spanish colonial period. To process raw wheat, local grist mills (molinos) were essential infrastructure as were the aceq uias (ditches) that powered them. Situated near the banks of rivers, the internal components of each mill were driven by the gravity force of water from an acequia, itself diverted from the river. Researchers have documented …

Advanced Quantitative Approaches To Unveil Social Inequities In Educational Contexts, Manuel J. Jiménez, Vanessa Svihla, Karl Benedict, Victor Law, Meeko Oishi

Organization, Information and Learning Sciences ETDs

Chapter 2 introduces an innovative method integrating Geographic Information Systems and Machine Learning to evaluate educational policy outcomes. This approach overcomes the limitations of traditional statistical methods and effectively analyzes complex relationships between educational data and demographic factors.

The study in Chapter 3 developed a prediction model for school report cards in New Mexico using census data and applying the methods described in Chapter 2. The accurate predictions suggested that the school accountability system disproportionately assigned failing grades to schools serving minoritized students. The study also confirmed that status measures depend more on demographics than growth measures.

The study in …

Indigenous Student Responses Of Resiliency To Adversity, Aaron Billie

Teacher Education, Educational Leadership & Policy ETDs

The purpose of this study was to analyze the responses of Indigenous students as they experience situations that are adversarial and precarious. One of the goals of this study was to empower voices of Indigenous students in providing an avenue to share their genuine stories of resilience. I served as both researcher and mentor as I applied a Navajo framework to the analysis of the data known as Nitl‘iz Saad bee Hozho Iina Sila (NSBHIS), or beautiful lifeways exist within the language of precious elements. The four areas of this framework held up the salient outcomes from the research which …

Understanding The Academic And Socio-Cultural Experiences Of Academically Underprepared Males And The Risk And Protective Factors Influencing Degree Attainment In A Community College System, Diego J. Trujillo

Teacher Education, Educational Leadership & Policy ETDs

This study aimed to identify the risk and protective factors that influence persistence, retention, and degree attainment among academically underprepared male students at a community college in Northern New Mexico. Understanding the context of developmental education was deemed crucial for this research, as open-access institutions, particularly community colleges, serve as the starting point for many students' educational journeys. Evaluating the experiences and educational pathways of these students is of great importance to address the existing achievement gaps. The research focused on understanding the experiences of these students and the factors that hindered or supported their persistence and degree completion.

Electromagnetic Simulations Of The Lansce Chopper Structure, Yusuf Sahin

Electrical and Computer Engineering ETDs

Particle accelerators are important for basic research as well as in applications such as ion implantation and cancer therapy. One important accelerator is the Los Alamos Neutron Science Center (LANSCE) located at Los Alamos National Laboratory (LANL) that primarily produces neutrons for research. The beam chopper simulation described here is a study to provide better modeling of this subsystem of LANSCE. A chopper is a device in which particles are intermittently sliced and directed to a target and/or experiment. The simulations in this thesis are used to analyze the correct operating parameters of the chopper. A good chopper model can …

Comparison Of Random Coupling Model To Stochastic Dyadic Green’S Function When Coupling To A Distributed Port, Evelyn Anne Dohme

Electrical and Computer Engineering ETDs

The Random Coupling Model (RCM) provides statistical representation of coupling between ports in a highly overmoded resonant cavity based on knowledge of radiation impedances of system ports and cavity properties. A recent variant of RCM, the Stochastic Dyadic Green’s Functions (S-DGF), provides the statistical distribution of fields in the cavity. By using Source Reconstruction Methods (SRM) to approximate equivalent surface currents, I hypothesized that the S-DGF can calculate the fields at their location, enabling a statistical estimate of the coupled power. Using nearfield radiation from simple patch antenna simulations and the SRM to estimate the equivalent fields and account for …

Speaker Diarization Of Noisy Classrooms From A Single Microphone Based On An Array Of Virtual Microphones And Machine Learning, Richard Briggs

Electrical and Computer Engineering ETDs

Speaker diarization from a single microphone is extremely challenging in noisy classroom environments. A new method based on simulating a microphone array has shown promising results, while requiring very little training. It used a minimum distance classifier to identify the speaker among a list of possible speakers. This thesis investigates machine learning methods for determining the speaker. The AOLME dataset that was used contains 758 samples totaling 894.4 seconds. Each is taken from a noisy classroom environment, focusing on five speakers - any one of whom could be active in a given sample - lasting an average of 1.2 seconds. …

The Third Domain Of T Cells In The Evolution Of Novel Immune Cell Types, Kimberly Anne Morrissey

Biology ETDs

αβ and γδ T cells play an essential role in the adaptive immune response and are present in the majority of jawed vertebrates. The T cell receptor (TCR) structure and genetic organization have been generally stable throughout 400 million years of gnathostome evolution. However, the TCRδ chain has displayed degrees of plasticity unseen in other TCR isoforms. One such form appears to be a chimera of a TCR chain with an antibody-like binding domain, known as VHδ and has been found a wide array of vertebrates including cartilaginous fish, coelacanths, amphibians, tuataras, birds, crocodilians, and monotreme mammals. Another, more extreme …

Investigating The Costs And Benefits Of A Nutritional Fungal Endosymbiont, Nolan L. Perryman

Biology ETDs

Research on insect symbiosis is dominated by insect–bacteria models, however, the role of fungal symbionts in insects is poorly understood. Fungi are de novo synthesizers of many essential nutrients, therefore, insect–fungal pairings can permit specialization on nutritionally deprived diets. Here, I address the costs and benefits of symbiosis using a system of beetle–fungal symbiosis. Specifically, I ask 1) when reared on a low-quality diet, does the beetle increase the number of viable symbionts to compensate for a heightened nutritional demand, and 2) Is the conferred fitness benefit of the symbiont only present in low-quality diets? When reared on low-quality diets, …
