Direct Observation Of Atomic Exchange During Surface Self-Diffusion, Matthew Aaron Koppa

Physics & Astronomy ETDs

The diffusion of adatoms across the (100) plane of iridium has been previously inferred to occur by an exchange mechanism based on site mapping. This study provides the first direct observation that surface self-diffusion can occur by exchange. Iridium enriched to ≥93% ¹⁹¹Ir was deposited onto an atomically clean and smooth Ir(100) plane as observed in an atom probe field ion microscope. Following thermally activated surface self-diffusion the adatom was field desorbed and mass analyzed. Observation of the ¹⁹³Ir isotope in one-half of the cases demonstrates conclusively that atomic exchange can occur during surface self-diffusion.

Retrofit Of Corroded Corrugated Metal Culverts Using Gfrp Slip-Liner, Rahulreddy Chennareddy

Civil Engineering ETDs

Culverts are water conveyance structures, typically used to allow water flow and maintain a balance between the flow streams without interrupting structures such as highways and bridges. Corrugated metal pipes (CMPs) have been used as culverts in North America since the 1950s because of their low cost and simple construction method. Today, the corrosion of CMPs is a major problem faced by all U.S. Departments of Transportation. There is an urgent need to provide an efficient solution, one that is corrosion-resistant, to retrofit thousands of corroded CMPs across the country. High specific strength, high strength to weight ratio, corrosion resistance, …

The Relationships Between Brain Function, Brain Structure, And Behavior In Children With Fetal Alcohol Speectrum Disorder, John Pinner

Psychology ETDs

Prenatal alcohol exposure (PAE), the leading cause of childhood developmental disability, has long-lasting effects extending throughout the lifespan. The teratogenic effects of PAE, not always physically discernable, may corrupt brain structure resulting in neural dysfunction. These aberrant effects often result in executive functioning deficits, associated with social and academic difficulties, which hinder typical development. As maternal alcohol use during pregnancy is heavily stigmatized, children without physical dysmorphology often go unreported and untreated; resulting in increased deficiencies compared to those more severely affected who receive early life interventions. This phenomenon requires the discovery of neurophysiological makers of PAE in order to …

Using Archaeological Remote Sensing To Evaluate Land Use And Constructed Space In Chaco Canyon, Jennie Odessa Sturm

Anthropology ETDs

Archaeological remote sensing includes a suite of non-invasive methods that can be used to study elements of the archaeological record that may not be achievable otherwise. Using primarily geophysical remote sensing, and especially ground-penetrating radar (GPR), three studies involving questions of “use” were conducted in Chaco Canyon, New Mexico. The first used GPR to study the built interior features of a single room in Pueblo Bonito to evaluate use and function of that room. Three categories of features were identified in the GPR data and confirmed with subsequent excavation. The second study used GPR to re-evaluate an enigmatic land use …

Basal Travertine Of The Bouse Formation: Geochemistry, Diagenesis And Implications For The Integration Of The Colorado River, Christina Ferguson

Earth and Planetary Sciences ETDs

The Pliocene Bouse Formation is discontinuously exposed in the lower Colorado River region and is a record of the first arrival of the Colorado River to the Gulf of California 5 million years ago. It consists broadly of a lower carbonate member (travertine, marl, and bioclastic units) and an upper siliciclastic member (claystone, mudstone, and Colorado River sands). This paper focuses on the basal travertine (synonymous with “tufa”) unit of the lower carbonate member. Because of its basal position and its chemical encrustation of pre-Bouse topography, the travertine can offer insight into the earliest depositional settings and may be a …

An Investigation Of The Chemistry, Thermodynamics And Catalytic Activity Of Molybdenum Carbides, Shanti Kiran Nayak

Chemical and Biological Engineering ETDs

These studies investigate the chemistry and stability of molybdenum carbides as an electrocatalyst. Due to their unique electronic properties, molybdenum carbides are purposed as electrocatalysts for reaction systems such as hydrogen evolution reaction, bifunctional water splitting and CO oxidation.

In this study, various synthesis processes were utilized to produce different types of molybdenum carbide with varying properties of particle size, surface area and excess carbon. The samples characterized by XRD accompanied by Whole Profile Fitting, Electron Microscopy, Gas Adsorption (surface area) and XPS.

These synthesis processes were refined using fundamental thermodynamic analyses. These analyses highlight regions of stability of different …

Freirean Pedagogy In Music Education, Tyler Slamkowski

Music ETDs

This is a qualitative, multiple case study rooted in grounded theory. It explores how music teachers might implement Paulo Freire’s theories in their classrooms, as well as best practices in Freirean music teaching. Paulo Freire was a Brazilian educational theorist who claimed that education, rooted in dialogue and co-creation of knowledge, could confront major structural injustices, such as inequality, exploitation, and violence.

The three participants in this study worked in the same large, Southwestern district. Participants were selected based on how their teaching fit with characteristics of Freirean Pedagogy. Three music educators, Robert, Eliza, and Jackie, the participants in this …

Implications Of The Modifiable Areal Unit Problem For Wildfire Analyses, Timothy P. Nagle-Mcnaughton, Xi Gong, Jose A. Constantine

Geography and Environmental Studies Faculty Publications

Wildfires pose a danger to both ecologies and communities. To this end, many large-scale analyses of wildfire patterns and behavior rely on the aggregation of point data to polygons, typically those based on distinct disparate ecological areas. However, the sizes, shapes, andorientations of the polygons to which data are aggregated are not neutral factors in the resulting analysis. The influence of the aggregation polygons on calculated results is known as the modifiable areal unit problem (MAUP), which is well-documented in the spatial statistics literature. Despite the documentation of the MAUP, relatively few wildfire studies consider the effects of the MAUP …

Labor Market Implications On The Uptake Of The Earned Income Tax Credit In New Mexico Post Great Recession: 2008-2015, James Kaminsky

Economics ETDs

The Earned Income Tax Credit (EITC) is one of the most successful poverty alleviation programs in the US tax code. In New Mexico tax filers may apply for a refundable credit – the Working Family Tax Credit (WFTC) – that is predicated upon receipt of the EITC on their federal return. However, the preponderance of research examining the efficacy of the EITC is premised upon two hypotheses: economic conditions are expanding and those seeking work can find it.

Subsequent to the Great Recession, it is not clear that these hypotheses hold. The Great Recession began in Q4-2007 and continued into …

Brief Of Professors Of Law, Us V. Bergdahl, Joshua E. Kastenberg, Rachel E. Vanlandingham, Geoffrey S. Corn

Faculty Scholarship

When scrutinizing executive actions for unlawful command influence, this Court must account for a president’s immense power over the military. The extant judicial test for unlawful command influence – a violation of due process in the military setting – is a contextual one, and hence must consider the unique and unparalleled authority of the Commander-In-Chief over the military and individual service-members when the president’s actions are at issue. This executive power should also be evaluated in light of its myriad, and historically important, constitutional and statutory constraints – some predating the birth of the United States – that appropriately continue …

Robot Motion Planning In Dynamic Environments, Hao-Tien Lewis Chiang

Computer Science ETDs

Robot motion planning in dynamic environments is critical for many robotic applications, such as self-driving cars, UAVs and service robots operating in changing environments. However, motion planning in dynamic environments is very challenging as this problem has been shown to be NP-Hard and in PSPACE, even in the simplest case. As a result, the lack of safe, efficient planning solutions for real-world robots is one of the biggest obstacles for ubiquitous adoption of robots in everyday life. Specifically, there are four main challenges facing motion planning in dynamic environments: obstacle motion uncertainty, obstacle interaction, complex robot dynamics and noise, and …

“Where Are You From?”: Using Critical Race Theory To Analyze Graphic Novel Counter-Stories Of The Racial Microaggressions Experienced By Two Angry Asian Girls, Talitha Angelica Acaylar Trazo, Woohee Kim

Intersections: Critical Issues in Education

This article uses critical race theory (CRT) to analyze two stories about racial microaggressions from Where Are You From?: Short stories about being Asian in America, the graphic novel written and illustrated by Talitha Angelica Acaylar Trazo in fulfillment of her undergraduate honors thesis. Where Are You From? visually historicizes the counter-stories of 48 Asian and Asian American students at a predominantly-white undergraduate institution. In this article, we examine these microaggressions in relation to institutional and structural racism and the intersections of race, gender, and power dynamics between white faculty and Asian female students. Furthermore, we propose …

Utilizing A Critical Literacy Framework To Discuss Issues Of Power And Privilege With Elementary Students, Barbara A. Pollard

Intersections: Critical Issues in Education

This action research study utilizes a critical literacy framework to bring issues of privilege and power into critical dialogue with elementary students. The study is based on the idea that disadvantaged groups can eventually agitate for societal change if they are prompted to begin to critically question systemic inequalities from a young age. Thus, instead of allowing dominant culture to dictate unfair norms and practices by simply abiding to the status quo, this study suggests that elementary teachers should aim to be the vehicle for transformational change by implementing pedagogy that encourages students to think deeply and critically. Over time, …

Disrupting Dis/Abilization: A Critical Exploration Of Research Methods To Combat White Supremacy And Ableism In Education, Sara H. Petit-Mcclure, Chelsea Stinson

Intersections: Critical Issues in Education

The following paper explores the way scientific research, as it is commonly defined, has been used to continue the marginalization and subsequent dis/abilization of students based on racial, cultural, and linguistic identities. Starting with a historical perspective, we trace the role of scientific research in the support of white supremacist, ableist societal mechanisms, as well as the emphasis on scientifically-based research in educational policy and practice. We call for an expansion of the definition of scientific research to emphasize mixed and multiple methods guided by the principles of participatory, emancipatory, and decolonizing methodologies.

Interpreting Amalgamation Processes Of A Fluvial Sandstone Of The Nacimiento Formation In The San Juan Basin, New Mexico, Keely Elizabeth Miltenberger

Earth and Planetary Sciences ETDs

Outcrop studies of fluvial sand bodies are important for the study of fluid transport and storage capabilities because the deposits are heterogeneous. 3-D photogrammetry was used to evaluate the amalgamation processes of a multi-storey sheet sandstone in the San Juan Basin, NM. The Angel Peak member was deposited in the proximal-medial transition of a distributive fluvial system by a meandering river during the Paleocene. Within the study area, amalgamation occurred by avulsion and reoccupation of channel-belts to produce five storeys of the multi-storey sheet sandstone. Within each storey is evidence of processes that are internal to a channel-belt, such as …

Dark Matter Production Beyond The Thermal Wimp Paradigm: An Exploration Of Early Matter Domination Scenarios, Jacek Ksawery Osinski

Physics & Astronomy ETDs

In the standard thermal history of the Universe, the energy density is dominated by radiation throughout the postinflationary era, until matter-radiation equality after big bang nucleosynthesis (BBN). However, we currently do not have any observational probes of the pre-BBN period, and radiation domination (RD) is therefore an assumption. Generic early Universe models predict the presence of additional components in the postinflationary Universe which can lead to periods of nonstandard evolution before the onset of BBN. A prominent example of such a period is a phase of early matter domination (EMD) in which the Universe undergoes matter-dominated expansion for a time, …

Reconstructing Energy Flow Through Modern And Historical Marine Communities: Insights From Amino Acid Isotope Analysis, Emma A. Elliott Smith

Biology ETDs

The fundamental currency of life is energy. Organisms need energy to grow, to survive and to reproduce. Understanding the acquisition of energy by consumers is thus a foundational aspect of biological research. This is especially important in the modern era, as impacts of ongoing anthropogenic effects will be mediated or amplified through food webs. Here, I explore how isotopic analysis of individual amino acids – a technique new to ecological studies – can be used to trace energy flow through animal communities in modern and ancient time periods. In particular, I focus on kelp forest food webs, which are nearshore …

Re-Reading Wilczek’S Remark On “Lost In Math”: The Perils Of Postempirical Science And Their Resolution, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Sabine Hossenfelder’s recent book “Lost in Math” has attracted numerous responses, including by notable physicists such as Frank Wilczek. In this article we focus on Wilczek’s remark on that book, in particular on the perils of postempirical science. We also discuss shortly multiverse hypothesis from philosophical perspective. In last section, we offer a resolution from the perspective of Neutrosophic Logic on this problem of classical tension between mathematics and experience approach to physics, which seems to cause the stagnation of modern physics.

Recent Experimental Findings Supporting Smarandache’S Hypothesis And Quantum Sorites Paradoxes And Subquantum Kinetic Model Of Electron, Victor Christianto, Robert N. Boyd, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Smarandache Hypothesis states that there is no speed limit of anything, including light and particles. While the idea is quite simple and based on known hypothesis of quantum mechanics, called Einstein-Podolski-Rosen paradox, in reality such a superluminal physics seems still hard to accept by majority of physicists. Here we review some experiments to support superluminal physics and also findings to explain Smarandache Quantum Paradoxes and Quantum Sorites Paradox. We also touch briefly on new experiment on magneton, supporting SubQuantum Kinetic Model of Electron.

Conclusion & Significance: Multiexperimental findings assessment allows one to verify conjectures by two of us (FS & …

Crustal Structure Beneath The East Coast Magnetic Anomaly From Seismic Refraction Tomography, Collin C. Brandl

Earth and Planetary Sciences ETDs

Syn-rift igneous addition is necessary for successful continental breakup. Past investigations of passive margins have focused on strike perpendicular structure, but potential field anomalies indicate that significant crustal variations may be present. Data from 21 ocean bottom seismometers was acquired as part of the Eastern North American Margin Community Seismic Experiment and was used for tomographic inversion to create 2D velocity models of the margin that are representative of crustal structure. Crustal thickness varies along-strike from ~20 km to ~24 km and a high velocity (Vp > 7 km/s) layer is present at the base of the crust above the Moho. …

Teachers’ Perspectives Of The Observation Process Within The Evaluation, Christine E. Lenhart

Teacher Education, Educational Leadership & Policy ETDs

One of the largest challenges for administrators is to create and implement teacher evaluation systems that help improve teaching and student learning. As policymakers and administrators have worked throughout the United States to develop and implement new teacher evaluation systems, teacher involvement in developing those teacher evaluation systems has been limited. Specifically, the evaluation process and the tools used in a state in the southwestern part of the United States to evaluate teachers do not incorporate teachers’ perspectives, yet they directly impact teacher standing, ability to receive tenure status, and, in some cases, their salary.

The purpose of this research …

A Cross-Linguistic Typology Of ‘Take’ Serial Verb Constructions, Taegyeong Lee

Linguistics ETDs

Serial verb constructions (SVCs) are multiple verbs forming a single predicate in a single clause (Aikhenvald 2006a, 2018). Serial verbs do not exhibit syntactic dependency between the verbs. Each of these verbs must occur on its own. The verb ‘take’ is one of the common verbs that occur in SVCs, and it tends to grammaticalize following numerous different paths. Yet, there are no studies with a considerable sample of ‘take’ SVCs. Moreover, the polysemy of ‘take’ SVCs has not been explored in detail. Based on Aikhenvald (2018)’s functional framework, the present study aims to examine ‘take’ SVCs in 45 languages …

The growing focus on accountability in higher education has included speculation about the most important measures of institutional success. Despite …

A Noncoherent Governance: Tinkering With Stones In The Old City Of Acre, Caitlin M. Davis

Anthropology ETDs

This dissertation recounts a series of episodes in the architectural conservation of the Old City of Acre in Israel. It studies the stones and mortars, residents and inspectors, papers and computers involved in the conservation of historic buildings, highlighting the moments in which the technical details of architectural conservation entangle themselves with the administrative techniques of government authorities. I describe architectural conservation as a tentative process, one that requires the coordination of various actants into precarious associations. Here, description is important. The pages that follow experiment with an anthropological practice that writes against conclusion. This is an anthropology that refuses …

Oral Development And Breastfeeding: An Assessment Of The Lactation Care Provider Approach, Robin Gatlin

Dental Hygiene ETDs

Breastfeeding influences the infant’s oral development in many ways. Lactation care providers work closely with the mother-infant pair and may be the first to provide information on oral health. The purpose of this study is to assess lactation care provider’s perception, attitude and behavior on the relationship between breastfeeding and oral development; including oral malocclusion, breathing patterns, tethered oral tissues and dental caries. A survey sent to lactation care providers who are members of The United States Lactation Consultant Association. A total of 12 members participated in the survey. Of that, 11 were International Board Certified Lactation Consultants (IBCLCs) and …

Influence Of Metabolic Capacity On The Consequences Of Spreading Depolarization, Katelyn M. Reinhart

Biomedical Sciences ETDs

In the United States, stroke is the fifth leading cause of death and stroke survivors often face long-term disability. After ischemic stroke, the ischemic territory can expand and recruit previously viable tissues into the lesioned area. During this critical period, there is an unsettling lack of interventions that prevent or treat secondary neuronal loss and cognitive decline. Clinical subdural recordings have revealed a close link between infarct progression and waves of spreading depolarizations (SD) in the acutely injured brain. SD is a slowly progressing wave of near-complete neuroglia depolarization that is extremely energetically demanding and this additional metabolic ‘hit’ …
