Science For All: Exploring Science Communication For Public Engagement In Culturally Diverse Scenarios In The Americas, Denisse Helena Vasquez-Guevara

Latin American Studies ETDs

Universities in the United States and Ecuador must meet various policy guidelines concerning research and teaching that address the needs of their local communities. In Ecuador, the higher education law requires that universities undertake research and public outreach projects that respond to societal needs. In the United States, Carnegie Research Classifications motivate universities to serve their publics by carrying out community-engaged research. However, evaluations of public outreach projects and community-engaged research have consistently demonstrated that the segments of society that are ostensibly served by these initiatives are not meaningfully engaged in them; members of the public are treated as, and …

Framing Of European Union Borders In Online News: Multimodal Discourses Of Inclusion And Exclusion, Ivana Cvetkovic

Communication ETDs

In times of crisis, online news media, on whose reports people heavily rely for information and interpretation of complex European affairs, play an important role in production of knowledge and negotiation of the meanings of the European Union’s response to the “migrant crisis” in 2015 when more than million migrants reached Europe after fleeing their home countries. This research project examines how European online news outlets constructed notions of borders, space, mobility and migration, and thus promoted particular institutionalized discourses on inclusion and exclusion with profound ideological implications. A secondary goal of this research is to explore the particular ways …

Teacher Perceptions Of Environmental Science In Rural Northwestern New Mexico Public Schools, Marie Quiahuitl Julienne

Organization, Information and Learning Sciences ETDs

In this study, I explored what teachers perceive as the factors that impact their teaching of environmental science in rural secondary level schools in northwestern New Mexico. I adapted Bronfenbrenner’s (1994) ecological systems model, based on four environmental subsystem levels (microsystem, mesosystem, exosystem, and macrosystem), as the conceptual framework to address the major research question of this study, and developed 18 interview questions to explore teachers’ perceptions of factors that influence their teaching of environmental science. I investigated the perspectives science teachers have about environmental science topics and the influences they perceive that affect how they teach environmental science, and …

Symmetry And Dopant Diffusion In Inverted Nanopyramid Arrays For Thin Crystalline Silicon Solar Cells, Seok Jun Han

Chemical and Biological Engineering ETDs

In this dissertation, we enhance the efficiency of thin flexible monocrystalline silicon solar cells by breaking symmetry in light trapping nanostructures and improving homogeneity in dopant concentration profile. These thin cells are potentially less expensive than conventional thick silicon cells by using less silicon material and making the cells more convenient to be handled when supported on polymer films. Moreover, these cells are widely applicable due to their flexibility and lightweight. However, for high efficiencies, these cells require effective light trapping and charge collection. We achieve these in cells based on 14-mm-thick free-standing silicon films with light-trapping arrays of nanopyramidal …

Microsphere-Based Disordered Photonic Structures: Control Of Randomness In Langmuir-Blodgett Assembly And Radiative Cooling Applications, Sarun Atiganyanun

Nanoscience and Microsystems ETDs

Many biological photonic structures in nature exhibit a significant degree of disorder within their periodic framework that enhances their optical properties. However, how such disorder contributes to the unique photonic characteristics is not yet fully understood. To facilitate studies on this topic, we investigated self-assembly of microspheres as a method to controllably introduce randomness to photonic structures. Specifically, we examined Langmuir-Blodgett assembly, a layer-by-layer fabrication technique. We developed and experimentally verified a model for the process and determined a condition of surface pressure and substrate pulling speed that corresponds to a maximum structural order in a layer. Along the trajectory …

Decolonizing Playwriting Through Indigenous Ceremonial Performances, Jay B. Muskett

Theatre & Dance ETDs

This dissertation attempts to express the importance of storytelling within the Indigenous Theater framework. It does so by first analyzing the progression of the writer’s unique upbringing and analyzing the influences of story upon an indigenous identity. I will also attempt to describe the aesthetics of Native Theater along two lines of methodology which includes praxis described and developed by Hanay Geiogamah and Rolland Meinholtz. I will also explain how the script 1n2ian tries to follow those concepts of Native Theater to create a ceremonial performance that uses a blending of both methodologies.

Fluid Transport In Porous Media For Engineering Applications, Eric M. Benner

Chemical and Biological Engineering ETDs

This doctoral dissertation presents three topics in modeling fluid transport through porous media used in engineering applications. The results provide insights into the design of fuel cell components, catalyst and drug delivery particles, and aluminum- based materials. Analytical and computational methods are utilized for the modeling of the systems of interest. Theoretical analysis of capillary-driven transport in porous media show that both geometric and evaporation effects significantly change the time dependent behavior of liquid imbibition and give a steady state flux into the medium. The evaporation–capillary number is significant in determining the time-dependent behavior of capillary flows in porous media. …

Cellular Modification And Artificial Cell Construction, Jimin Guo

Chemical and Biological Engineering ETDs

With all its complexities and different biofunctionalities, a cell is the basic structural and functional unit of all living organisms with the exception of viruses. In this dissertation, I demonstrated gain of function strategies of modifying mammalian cells using silicification and modular nanoparticle (NP) exoskeletons. In addition, I used a modular design concept to build a multifunctional artificial RBC system which can mimic the unique characteristics (e.g. shape, flexibility, the ability to carry oxygen, and long circulation times) of the native RBCs. Together, these cell modification or artificial cell construction strategies are expected to generate new mammalian cell-like structures with …

The Dark Horse: An Analysis Of The Experiences And Practices Of Female Collegiate Band Directors, Katharine Grace Henderson

Music ETDs

Using a multi-case interview process, the experiences and practices of three female collegiate band directors were analyzed for trends and patterns. These directors were found using the Women Band Directors International membership directory and chosen using purposeful criteria. After analyzing the findings, several patterns were uncovered. First, there is an overwhelmingly negative environment towards females at professional conferences. There is also a lack of female role models for female students who might wish to pursue a conducting career. As a result, they might not realize that conducting is even an option for them. Additionally, there was not one method of …

Urban In Nature: Yosemite, Cars, And California's Cities, 1913–1970, Guy Mcclellan

History ETDs

The impacts of national parks do not stop at their borders, and neither should their histories. Located less than a day’s drive from California’s biggest cities, Yosemite National Park remains a product of their combined influences. “Urban in Nature” is a relational history of the park and its nearby metropolitan areas like Merced (70 miles away), Berkeley (180), San Francisco (200), and Los Angeles (300).

Since the advent of the automobile Yosemite has been a mirror of the state’s urban areas, rather than an escape from them. Passenger cars drove Yosemite’s urbanization in two interconnected ways. Firstly, increasing amounts of …

Exploration, Disruption, Diaspora: Movement Of Nuevomexicanos To Utah, 1776-1850, Linda Catherine Eleshuk Roybal

American Studies ETDs

ABSTRACT

Nuevomexicano villages of northern New Mexico have experienced disruptions throughout their existence. This dissertation is a study of what occurred in early disruptions leading to the great departure of the 1940s, during World War II and immediately following, known as the New Mexico diaspora, where a number of villagers moved out of New Mexico to other states, including Utah, most expecting to settle for a time with hopes of return to their home villages. The study asks what happened especially during the great disruption, discourses of disruption and movement, what Nuevomexicanos carried with them in movement, whether they returned …

Quantitative fluorescence microscopy is a highly technical, swiftly evolving field of methodologies that are uniquely able to probe the nano-scale biological environment. With these optimized, advanced technologies available, scientists and medical providers are equipped to illuminate a plethora of puzzles in science and medicine through the multiplexing and high spatiotemporal resolution offered. Here I first exploit these capabilities to study a rare cancer with multiplex immunohistofluorescence (IHF) to confirm cell type and undocumented protein expression that may have implications for our understanding of the biology of mast cells and the potential efficacy of treatment and symptom management in mast cell …

Topics In Three-Dimensional Imaging, Source Localization And Super-Resolution, Zhixian Yu

Physics & Astronomy ETDs

The realization that twisted light beams with helical phasefronts could carry orbital angular momentum (OAM) that is in excess of the photon's spin angular momentum (SAM) has spawned various important applications. One example is the design of novel imaging systems that achieve three-dimensional (3D) imaging in a single snapshot via the rotation of point spread function (PSF).

Based on a scalar-field analysis, a particular simple version of rotating PSF imagery, which was proposed by my advisor Dr. Prasad, furnishes a practical approach to perform 3D source localization using a spiral phase mask that generates a combination of Bessel vortex beams. …

Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller

Geography ETDs

Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …

As a verification of our pulses having high peak powers and ultrashort durations, they were then used to strike water, glass, and a Kerr Cell. Supercontinuum generation was observed as …

Effects Of Chemogenetic Inhibition Of Ventral Hippocampal Glutamatergic Neurons On Anxiety-Like Defensivity In Male Long-Evans Hooded Rats, Carlos R. Maestas-Olguin

Psychology ETDs

Previous research in rodents and humans has implicated the ventral hippocampus in regulating anxiety. However, many rodent studies examining ventral hippocampal neuronal pathways have utilized lesions that create nonspecific and/or nonreversible damage to the region. The present study sought to characterize the role of ventral hippocampal glutamatergic pyramidal neurons in modulating anxiety-like behavior during exposure to a variety of threatening stimuli. Five weeks prior to testing, male Long-Evans hooded rats received ventral hippocampal viral-vector infusions expressing either pAAV-CaMKIIα-hM4D-mCherry (DREADD) or pAAV-CaMKIIa-EGFP (GFP). DREADD transfection allowed for the specific, noninvasive and temporary inhibition of ventral hippocampal glutamatergic neurons immediately before threat …

Metabolon-Inspired Design Of Multi-Modal Catalytic Cascade, Madelaine Seow Chavez

Chemical and Biological Engineering ETDs

Developing hybrid catalytic systems has been researched for the past decade in an effort to efficiently incorporate catalysts of different modalities in catalytic cascades. It has become imperative to design a cascade system where the catalysts are spatially organized to control the delivery of precursors, intermediates, and products. In this work, we have shown that a molecular catalyst, biocatalyst, and metallic catalyst can be co-localized using a carbonaceous support to create a hybrid catalytic system and complete the oxidation of oxalic acid to create a microchemical reactor. The molecular, pyrene-TEMPO catalyst oxidizes glyoxalic acid to oxalic acid. The enzyme oxalate …
