A Case Study Of Two Taiwanese Students With Hearing Loss Navigating The English As A Foreign Language Requirement At Their University, Yu Chen

Language, Literacy, and Sociocultural Studies ETDs

Many institutions of higher education (IHE) students in Taiwan now need to meet the English proficiency requirement to earn their higher education degrees. In this case study, I intended to a) provide the opportunity for IHE students with hearing loss in Taiwan to share their opinions, thoughts, and experiences of learning English as a foreign language in higher education institutes; and b) understand how English as a foreign language policies and educational practices contribute to create opportunities and barriers for IHE students with hearing loss. The research question I intended to examine was “what are the perceptions of the lived …

Anodic Catalysts For Anion Exchange Membrane Fuel Cells, Aaron Joseph Roy

Chemical and Biological Engineering ETDs

With a limited availability of energy resources from petroleum and other fossil fuels, as well as growing concerns relating to the environmental implications of fossil fuel emissions, non-carbon fuels which can be utilized in proton and anion exchange membrane fuel cells (PEMFC’s/AEMFC’s), such as hydrogen and hydrazine hydrate (HH), are becoming more attractive as alternative fuels. Historically, platinum and platinum group metal catalysts (PGM) have been used as cathode and anode catalyst materials for both PEMFC’s and AEMFC’s. Although these catalysts are the highest performing catalysts available for the conversion of hydrogen energy in fuel cells, the limited availability and …

(Dis)Appearing Subjects: Managing Violence Through The Discourse Of Bullying, Rachel E. Levitt

American Studies ETDs

In the early 2000’s, “bullying” became the new center of LGBTQ justice organizing. As part of this development a bullied subject emerged. This bullied person on whose behalf liberation was being sought took various forms from the bullied school shooter, to the cyberbullying victim, to the bullied suicidal queer. As the subtitle of my dissertation suggests, I focus on “managing violence through the discourse of bullying.” This marks a two part process: how the discourse of bullying manages to do violence and how it manages populations biopolitically. This study tackles one of the core paradoxes that inform the formation of …

Direct Potable Reuse In Small-To-Medium Sized Inland Communities: Lessons Learned For Public Education And Outreach, Claudia B. Pratesi

Architecture and Planning ETDs

Drought, growing populations, and potential conflict over water in the American Southwest have water authorities examining highly treated wastewater as an option to augment municipal supplies. Direct potable reuse (DPR) holds promise for improving sustainability and reliability of potable water supplies by generating high-quality drinking water from wastewater. Despite research demonstrating that DPR can be safe, one of the biggest hindrances to DPR is negative public perception. Attempts to implement some DPR project have failed, while others have proceeded quickly. Using insights from the literature and interviews with water managers, this study aims to: (1) examine existing community conditions related …

High Power Microwave Metamaterial Based Passive And Active Devices, Hamide Seidfaraji

Electrical and Computer Engineering ETDs

The goal of this dissertation is to design novel metamaterials for High Power Microwave devices. Metamaterials (MTM) are artificial periodic structures, which support reversed Cherenkov radiation and backward wave propagation. Microwave sources transform the kinetic energy of an electron beam into microwaves through the interaction of the electrons with a periodic slow wave structures (SWS). Here, a metamaterial (MTM) waveguide is proposed for use in a microwave oscillator instead of a SWS. The interaction of a multi-beam cathode with a set of MTM structures inside a cylindrical waveguide is studied and analyzed.

Group theory is used to design a metamaterial …

Hydrogeochemical Investigation Of Recharge Pathways To Intermediate And Regional Groundwater In Cañon De Valle And Technical Area 16, Los Alamos National Laboratory, Brendan W. Brady

Civil Engineering ETDs

In aquifers consisting of fractured or porous igneous rocks, as well as conglomerate and sandstone products of volcanic formations, silicate minerals actively dissolve and precipitate (Eby, 2004; Eriksson, 1985; Drever, 1982). Dissolution of hydrated volcanic glass is also known to influence the character of groundwater to which it is exposed (White et al., 1980). Hydrochemical evolution, within saturated zones of volcanic formations, is modeled here as a means to resolve the sources feeding a perched groundwater zone. By observation of solute mass balances in groundwater, together with rock chemistry, this study characterizes the chemical weathering processes active along recharge pathways …

We Walk With Time, Time Does Not Walk With Us, Angelina L. Grey

Architecture and Planning ETDs

The conceptual framework of Indigenous placemaking is defined as a fundamental and complex approach to the processes of the Indigenous planning paradigm. To identify placemaking is to acknowledge and recognize Indigenous place-based knowledge as essential planning tools when working with Indigenous communities. Colonization and western acculturization adjudicated the divestment of Indigenous languages and cultures through western policies and Indian school education. Today, Indigenous worldviews are tainted with extreme levels of sociocultural disparities. The implementation of Indigenous planning processes establishes an understanding to Indigenous community-building through shared knowledge and collaboration. The concepts of placemaking thus enables and empowers Indigenous communities to …

Our History Is The Future: Mni Wiconi And The Struggle For Native Liberation, Nick Estes

American Studies ETDs

From April 2016 to February 2017, Indigenous women and youth led a historic struggle to halt the construction of the Dakota Access Pipeline from crossing Mni Sose, the Missouri River, and threatening the drinking water of the Standing Rock Indian Reservation and millions downstream. Rallied under the banner Mni Wiconi, a Lakota assertion meaning “water is life,” centuries of history converged during the protests. It was about more than an oil pipeline. It was struggle over the meaning of history, the defense of land and water, and the rights of Indigenous peoples to determine their own future. When land and …

Integration Of Thin Film Tpv Cells To Cvd Diamond Heat Spreaders, Emma J. Renteria

Electrical and Computer Engineering ETDs

In this work, techniques to isolate thermophotovoltaic (TPV) devices from the growth substrate and their subsequent integration with Chemical Vapor Deposition (CVD) diamond heat spreaders will be discussed, with the envisioned goal of fabricating thermally managed cells. CVD diamond heat spreaders are a great option for thermal management of TPV cells. The key requirement, however, is the bonding of the TPV cell directly onto the diamond wafer without the presence of thick (>350 μm) growth substrates, which can offer significant thermal resistance.

The first approach is to release GaSb epitaxial layers from GaSb substrates. However, this is challenging due …

Evaluation Of Energy Released From Nuclear Criticality Excursions In Process Solutions, Corey Michael Skinner

Nuclear Engineering ETDs

Typically, the staff of a nonreactor nuclear facility or a processing facility involving nuclear material are not expected to have a strong technical background in nuclear criticality physics, as that is not the purpose of these sites, yet handle material with the potential to undergo a criticality excursion. Such excursions have occurred 22 times in the past, 21 of which involved an aqueous solution material. Therefore, it would be useful to have a general model capable of providing a quick estimation of the consequences of a criticality excursion in a processing plant. To this end, correlations developed utilizing experimental data …

Discourse Changes Following Severe Traumatic Brain Injury: A Longitudinal Study, Elizabeth Young

Speech and Hearing Sciences ETDs

Purpose: There are few longitudinal data charting recovery of discourse skills following severe traumatic brain injury (TBI). Limited knowledge about the trajectory of discourse recovery and the best tools for assessing communication abilities in persons with TBI (PWTBIs) restricts detection of communication impairment and the ability to make informed prognostic judgments following TBI. This study sought to contribute longitudinal data to the research base, using clinically efficient measures that are sensitive to communication deficits associated with TBI and that use nuanced scoring systems to provide detailed characterization of discourse.

Methods: Twenty-three PWTBIs completed picture description tasks at 3 (or 6) …

Microbial Desalination Cells With Efficient Platinum Group Metal-Free Cathode Catalysts, Morteza Rezaei Talarposhti

Chemical and Biological Engineering ETDs

Iron-nitrogen-carbon based catalyst was used at the cathode of a microbial desalination cell (MDC) and compared with platinum (Pt) and activated carbon (AC) cathode. Fe-N-C catalyst was prepared using nicarbazin (NCB) as organic precursor by sacrificial support method (SSM). Rotating ring disk electrode (RRDE) experiments shows that Fe-NCB had higher electrocatalytic activity compared to AC and Pt. The utilization of Fe-NCB into the cathode improved substantially the performance output with initial maximum power density of 49±2 μWcm^-2 in contrast to Pt and AC catalysts which have shown lower values of 34±1 μWcm^-2 and 23.5±1.5 μWcm^-2, respectively. …

Bacterial Siderophore Production In Lechuguilla And Spider Caves, Carlsbad National Park (Ccnp) Carlsbad, New Mexico, Tammi R. Duncan

Biology ETDs

Lechuguilla and Spider caves, Carlsbad Caverns National Park, contain a rich microbial diversity. Despite oligotrophic conditions, the microorganisms in these caves have developed strategies to acquire essential nutrients. I hypothesized that cave bacteria use siderophores, a ferric iron chelating compound, to acquire iron for essential life processes. To understand the backdrop against which the cave bacteria would produce siderophores, I examined the bacterial physiological characteristics, determined whether cave bacteria have an ability to produce siderophores, and investigated a possible correlation between iron and manganese concentrations in cave deposits and siderophore production by bacteria cultured from the same site. I carried …

Applying Heterogeneous Teams Of Robotic Agents Using Hybrid Communications To Mapping And Education, Jonathan M. West

Electrical and Computer Engineering ETDs

Robotic agents are being increasingly utilized to carry out tasks that are difficult or dangerous for humans. Many of these missions are best performed by heterogeneous teams of agents with various individual abilities. Communication among agents and with operators is a critical element in the performance and efficiency of these missions. Although radio frequency communications dominate the robotic networking field, they are limited in range and bandwidth due to spectrum congestion and subject to interference from noise or hostile jamming and can be intercepted. Optical communication has many advantages such as higher bandwidth and focused beam, however the line-of-sight requirement …

Proposed Method For Measuring The Let Of Radiotherapeutic Particle Beams, Stephen D. Bello

Physics & Astronomy ETDs

The Bragg peak geometry of the depth dose distributions for hadrons allows for precise and effective dose delivery to tumors while sparing neighboring healthy tissue. Further, compared against other forms of radiotherapeutic treatments, such as electron beam therapy (EBT) or photons (x and \(\gamma\)-rays), hadrons create denser ionization events along the particle track, which induces irreparable damage to DNA, and thus are more effective at inactivating cancerous cells. The measurement of radiation's ability to inactivate cellular reproduction is the relative biological effectiveness (RBE). A quality related to the RBE that is a measurable physical property is the linear energy transfer …

Porous Time And Space In Contemporary Photography: How Social Constructions Of Space And Reenactment Produce Alternative Histories, Emma Brooke Lehrer Stein

Art & Art History ETDs

This dissertation examines how the photograph can exceed the long-rooted debate around medium specific notions of photographic truth, since all realisms are historical and constantly changing. Applying theories of socially constructed space and porous time to analysis of these case studies presents alternative photographic histories that show past and present together. Boris Mikhailov, as a dissident artist and post-Soviet documentarian of new Russian capitalism, presents histories of visual culture that compete and overlap during the Soviet era and afterward. Mikhailov refers to the multiplicity of voices found in his photographic practice as a state of “coexistence.” Looking at photographs of …

Cultural Imprint: A History Of Northwest Coast Native And First Nations Prints, India Rael Young

Art & Art History ETDs

Cultural imPRINT provides the first substantive art historical investigation into Northwest Coast Indigenous prints. Since the 1960s, Northwest Coast artists have employed the print medium to share their histories, heritage, and culture amongst each other and with the larger world. Because print artists number in the hundreds, and print editions in the thousands, this dissertation takes a socio-cultural approach to understanding the purposes for the medium’s production and circulation. First, it analyzes the deep histories of reproduction in the North American art world and in Northwest Coast Indigenous communities, asserting that reproduction within coastal communities serves to perpetuate history from …

Improving Large Scale Application Performance Via Data Movement Reduction, Dewan M. Ibtesham

Computer Science ETDs

The compute capacity growth in high performance computing (HPC) systems is outperforming improvements in other areas of the system for example, memory capacity, network bandwidth and I/O bandwidth. Therefore, the cost of executing a floating point operation is decreasing at a faster rate than moving that data. This increasing performance gap causes wasted CPU cycles while waiting for slower I/O operations to complete in the memory hierarchy, network, and storage. These bottlenecks decrease application time to solution performance, and increase energy consumption, resulting in system under utilization. In other words, data movement is becoming a key concern for future HPC …
