Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow

Electronic Theses and Dissertations

Avian facial plumage, bill coloration, and feather microstructure may serve one or more adaptive functions. Several researchers have proposed that dark eyestripes, bills, and facial masks aid in reducing glare, however, there have been relatively few tests of this hypothesis. Dark facial markings have been shown to have an adaptive glare-reduction function in recent field studies of a few species, but this hypothesis has never been tested in a broad multispecies analysis. It is likely that feather microstructure influences feather brightness and has an effect on the efficacy of glare reduction properties of feathers. I examined the link between dark …

Characterization Of Surface Karst Using Lidar And Field Traverses, Fort Hood Military Installation, Coryell County, Texas, Heather Jaclyn Dailey

Electronic Theses and Dissertations

The Fort Hood Military Installation is a karst landscape that has been significantly altered for training exercises that include heavy vehicle maneuvers and simulated combat. Traditional karst surveys are often time-consuming and require extensive field analyses to adequately characterize large areas. Bias is given to areas that are most easily accessible and false negatives are common. Previous studies conducted in the eastern and western portion of the base have understated the abundance and spatial distribution of karst, particularly in the western portion.

This study used field traverses and 0.5-meter Light Detection and Ranging (LiDAR) data to characterize surface karst depressions, …

Effects Of Increased Atmospheric Carbon Dioxide Levels On Tobacco Mosaic Virus And Root-Knot Nematodes In Genetically Resistant And Susceptible Tomato Plants, Angie Nicholas

Electronic Theses and Dissertations

Rising atmospheric carbon dioxide (CO₂) may affect plant/pathogen interactions. This study focused on the effects of elevated CO₂ on Root-Knot Nematode (Meloidogyne arenaria) and Tobacco Mosaic Virus (TMV) infection in genetically resistant versus susceptible tomatoes (Solanum lycopersicum). Both resistant and susceptible tomatoes were grown in chambers with either ambient CO₂ or CO₂ elevated to 750 ppm and infected with M. arenaria or TMV. Measurements were taken at regular intervals to determine the effects of the pathogens on the plants. Resistant plants infected with M. arenaria maintained resistance while susceptible plants remained …

The film provides a canvas upon which a musically dominant multimedia experience is built. An accompanying analysis explains the variety of compositional techniques used, explaining their significance and how each deviates from a traditional film score. The objective of this work is to challenge the existing relationship between music and film, and add to the growing body of repertoire of live works featuring synchronized video, modeling example methods of live multimedia performance. In this exploration, the goal was not to be anti-cinematic, …

Investigating Dorsal Fin Hydrodynamic Function Of The Lemon Shark, Negaprion Brevirostris, Vivian Lynn Turner

Electronic Theses and Dissertations

Many sharks are considered highly efficient swimmers. Their swimming efficiency is partially governed by their morphological features such as dorsal fins, which play a role in their hydrodynamics. Most sharks feature two dorsal fins that can vary in size and location over the body. The first dorsal fin has been shown to improve stabilization, maneuverability, and increase thrust production during swimming, whilst the hydrodynamic role of the second dorsal fin is largely unknown. An understanding of the hydrodynamic function of the dorsal fins can be utilized in engineering applications, e.g., to replicate fins on underwater autonomous vehicles to increase energy …

Personality In Stomatopod Crustaceans, Jillian Page Blenderman

Electronic Theses and Dissertations

Stomatopods, or mantis shrimp, are small, predatory crustaceans of tropical and subtropical waters. Mantis shrimp research has focused largely on their agonistic interactions and complex visual systems. Despite their broad behavioral repertoire, stomatopods have not yet been investigated for consistent behavioral differences at the individual level, referred to as animal personality. Fifteen individual Neogonodactylus oerstedii were tested in three scenarios designed to measure potential differences in behaviors: 1) exploration of a novel environment, 2) response to and recovery from a startling event, and 3) response to a novel object. Each individual went through the series of tests twice, with a …

Comparing Traditional And Modern Trends In Jazz Improvisation, Ryan M. Johnson

Electronic Theses and Dissertations

This thesis compares traditional and modern jazz improvisation through analysis. These analyses discuss various musical techniques and ideas specific to each differing era. The case studies focus on three traditional jazz standards: "Autumn Leaves," "Someday My Prince Will Come," and "Cantaloupe Island." Two solo transcriptions (one traditional and one modern) represent each tune, including performances by Bill Evans, Miles Davis, Paul Desmond, Herbie Hancock, Yohan Kim, and Cory Henry. The older transcriptions showcase classic chord-scale relations, diatonic chord harmony, consistent rhythms with spacious phrasing, and recalled material. The newer transcriptions consist more of dense harmony, scales independent from the composed …

Nyku: A Social Robot For Children With Autism Spectrum Disorders, Dan Stephan Stoianovici

Electronic Theses and Dissertations

The continued growth of Autism Spectrum Disorders (ASD) around the world has spurred a growth in new therapeutic methods to increase the positive outcomes of an ASD diagnosis. It has been agreed that the early detection and intervention of ASD disorders leads to greatly increased positive outcomes for individuals living with the disorders. Among these new therapeutic methods, Robot-Assisted Therapy (RAT) has become a hot area of study. Recent works have shown that high functioning ASD children have an affinity for interacting with robots versus humans. It is proposed that this is due to a less complex set of communication …

What Happens Next? A Grounded Theory Exploration Of The Psychological Impact Of Leaving The Gang, Alana C. Liskov

Electronic Theses and Dissertations

Very little research exists regarding the psychological impacts of gang membership and the mental health needs of gang members. Of the few studies that have been conducted, gang members were found to have increased rates of post-traumatic stress disorder (1.77 odds), current substance abuse (2.58 odds), oppositional defiant disorder, (1.24 odds) and conduct disorder (4.05 odds) (Harris, Elkins, Butler, Shelton, Robles, Kwok, Simpson, Young, Mayhew, Brown, & Sargent, 2013). Violent ruminative thinking, violent victimization and fear of further victimization were also significantly higher in gang members and believed to account for high levels of psychosis and anxiety disorder in gang …

Quantification Of Mitochondrial Zinc Homeostasis And Analysis Of Zinc And Polyamine-Mediated Axonal Trafficking, Dylan Hunt Fudge

Electronic Theses and Dissertations

The zinc ion is an important emerging signaling molecule for biological processes. In this work we engineered improved zinc sensors based on our previously developed fluorescent sensor GZnP1 to provide sensors with a higher fluorescent readout, faster kinetics, and a superior sensitivity to zinc. We utilized these zinc sensors and further developed the sensors to answer questions pertaining to biological zinc. We showed the labile zinc concentration in the mitochondrial matrix was less than 1 pM while the labile zinc concentration in the cytosol and mitochondrial IMS were comparable (~100 pM) across four different cell lines. Using these zinc sensors …

The Eu Ets: A Critical Analysis, Marceline Grey Swan

Electronic Theses and Dissertations

Carbon markets, established via cap & trade programs, are the dominant means by which climate stabilization is currently being pursued worldwide, with many centered around the European Union’s Emissions Trading Scheme. As such, a critical analysis of the EU ETS & its effectiveness is crucial to assess whether the EU carbon market is an effective mechanism to achieve climate stabilization. The effectiveness of the overall program was evaluated via a determination of whether the EU ETS, & to a greater extent the EU carbon market, has allowed for emissions reductions in line with the goal for climate stabilization set by …

Spontaneous Minds And Electric Romanticism: Kerouac, Ginsberg, Dylan, Joplin, Sasha Tamar Strelitz

Electronic Theses and Dissertations

This dissertation postulates a sub-category of Romanticism: electric Romanticism. As opposed to its “acoustic” forebear, electric Romanticism exists in an electric age, beginning after Henry David Thoreau’s rumination on the telegraph wire as an electric rendering of the æolian harp image. Romantic poets used the æolian harp to analogize the act of writing activities set into motion by spontaneous thoughts, a central attribute of the Romantic literary movement. The modernized electric version of the æolian harp—the telegraph wire—signals that electric Romanticism branches off from its source and evolves along with technology to engage more synchronously with the spontaneous.

Electric Romantics …

Epochs Of Ecology: The Transition From Feudalism To Capitalism, Jacob Alexander Tucker

Electronic Theses and Dissertations

The transition from feudalism to capitalism has undoubtedly been one of the most fruitful and complicated debates amongst economic historians in the 20th and 21st centuries. With the advent of global ecological collapse, there is a necessity to examine and theorize the movement from feudalism to capitalism through the lens of ecology. While in mainstream economics the environment is either entirely dismissed or nature’s role in economics remains subsidiary to the human economy, in the field of Marxian economics, human’s interacting through nature is at the core of the entire theory. For that reason, this thesis takes earnestly Marx’s contributions …

Digitizing The Aura: A Systems Update For The Contemporary Art World, Emilie Trice

Electronic Theses and Dissertations

During the digital tide of the last several decades, the material, metaphysical and economic properties of art have evolved in response to the ever-accelerating growth of cybernetics. The contemporary art ecosystem (CAE) has long been considered “the last unregulated financial market”; then cryptocurrency was invented. Now, blockchain technology has entered the cultural zeitgeist and could radically innovate numerous industries, including the art market. The CAE itself is a network, a system that operates within fundamental parameters and, in that sense, it shares much in common with the philosophies underlying computation, such as systems theory, complexity theory and emergent consensus mechanisms. …

People And Place: A Journey Through Film, Tourism, And Heritage, Sarah Beals

Electronic Theses and Dissertations

Old Tucson Studios is a theme park where film, tourism, and heritage all converge through the American Western genre. During national social change, Westerns increase in number to reflect national values and identity. Westerns that ally with landscapes and people are potentially the most powerful storytelling tool in mainstream media. My research shows that this paring of people and place creates a prevailing image in the audience’s memory. The results suggest that the current image of the West comes from films made between 1951-1970, despite there being newer Westerns. John Wayne and saguaro cactus are enduring images with historic, cultural, …

Using Natural Language Processing To Categorize Fictional Literature In An Unsupervised Manner, Dalton J. Crutchfield

Electronic Theses and Dissertations

When following a plot in a story, categorization is something that humans do without even thinking; whether this is simple classification like “This is science fiction” or more complex trope recognition like recognizing a Chekhov's gun or a rags to riches storyline, humans group stories with other similar stories. Research has been done to categorize basic plots and acknowledge common story tropes on the literary side, however, there is not a formula or set way to determine these plots in a story line automatically. This paper explores multiple natural language processing techniques in an attempt to automatically compare and cluster …

Cellular And Developmental Insights Into The Early Evolution Of Muscle, Jeffrey J. Colgren

Electronic Theses and Dissertations

Whereas a great deal has been learned about the molecular underpinnings of morphological evolution in animals, much less is known about the origin of novel cell and tissue types. During the time in which the earliest animal lineages were diversifying, fundamental cell and tissue types, such as muscles, arose. Sponges are one of two animal lineages that lack muscles, yet they undergo coordinated full body contractions. Whereas the signaling processes have been studied, the physical mechanisms of contraction are completely uncharacterized. The main purpose of this work is to understand the primary contractile tissue of the sponge Ephydatia muelleri, …

Dis/Ableist Consumption: A Critical Thematic Analysis Of Avowed And Ascribed Neuro-Identities In The Classroom, Shaundi C. Newbolt

Electronic Theses and Dissertations

In the United States, faculty and students are publicly claiming neurodivergent identities and support for the neurodiversity movement. This study uses Collier and Hecht’s cultural identity theories with Lang and Chen’s two-step process, critical thematic analysis (CTA), to examine avowals and ascriptions with four diagnostic terms, ASD, ADHD, bipolar disorder, and dyslexia, of students and professors from Rate My Professors (RMP) with Ritter’s frame of RMP as a phenomenon.

A total of 1,022 posts are analyzed to understand how students resist or re-inscribe popular medical model/deficit discourse in the classroom: student avowals (N = 232), professor avowals (N = 51), …

The Interplay Between Economic Growth And The Environment: The Case Of China, Christian D. Carpio-Thomas

Electronic Theses and Dissertations

Historically, economic development has come at the cost of environmental degradation. Since the 1980s, neoliberalism rooted in neoclassical theory has dominated mainstream economic thought. The result has been a dramatic increase in environmental degradation in favor of economic growth. The neoliberal recommendations toward development are encapsulated in the Washington and post-Washington Consensuses which promote the liberalization of trade and foreign investment as well as a reliance on market mechanisms. Ultimately, the goal of neoliberalism is to generate growth regardless of the impact that it places on the environment. The case of China presents an example of an economy which pursued …

Ehbp1 And Ehd2 Regulate Dll4 Caveolin-Mediated Endocytosis During Blood Vessel Development, Amelia Margaret Webb

Electronic Theses and Dissertations

During angiogenesis, the development of new blood vessels from existing vessels, there must be tight regulation between a leading tip cell and trailing stalk cells during vascular patterning. Lateral inhibition produced by Notch signaling is central to the specification and maintenance of tip and stalk cells in growing angiogenic sprouts. The Notch pathway is activated by the ligand Delta at adherens junctions between tip and stalk cells. Despite the centrality of Delta/Notch signaling to angiogenesis, relatively little is known about the mechanism of this signaling event. It has been proposed that the force generated by the Notch bound Delta ligand …

The Colored Pill: A History Film Performance Exposing Race Based Medicines, Wanda Lakota

Electronic Theses and Dissertations

Of the 32 pharmaceuticals approved by the FDA in 2005, one medicine stood out. That medicine, BiDil®, was a heart failure medication that set a precedent for being the first approved race based drug for African Americans. Though BiDil®, was the first race specific medicine, racialized bodies have been used all throughout history to advance medical knowledge. The framework for race, history, and racialized drugs was so multi-tiered; it could not be conceptualized from a single perspective. For this reason, this study examines racialized medicine through performance, history, and discourse analysis.

The focus of this work aimed …

The African State: An Illusory Vestige Of Colonialism, Muhammad K. Otaru

Electronic Theses and Dissertations

In a 2006 Interview, prominent Nigerian author, and social commentator, Chimamanda Ngozi Adichie said; “…Nigeria was set up to fail. The only thing we Nigerians should take responsibility for is the extent of the failure….”1. Such a view about colonialism and the states it arbitrarily created is widely shared by many on the African continent, who have come to understand that the very creation and existence of the African state are largely to blame for the seemingly countless socio-economic and political issues faced on the continent.

Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout

Electronic Theses and Dissertations

Land use activities have caused disturbances that affect the quality of freshwater ecosystems worldwide. How the influences of land use along an environmental gradient and the associated environmental variables that may influence stream diversity and function is unclear. We address these issues by studying biodiversity, abundance, and functional diversity of macroinvertebrates across different land types along a gradient in Colorado, USA. We also address how diversity may change along an elevation gradient by analyzing previously published macroinvertebrate research. We found evidence that land use and disturbance are stronger explanations of changes in macroinvertebrate communities, rather than elevation. Functional trait patterns …

This Ph.D. dissertation focuses on studying the feasibility and effectiveness of using a social robot, called NAO, and a toy music instrument, xylophone, at modeling and improving the social responses and behaviors of children with ASD. In our investigation, we designed an autonomous social interactive music teaching system to fulfill this mission.

A novel modular robot-music teaching system consisting of three modules is presented. Module 1 provides an autonomous self-awareness positioning system for the …

Immortal Combat: Iconoclasm And The Hebrew Bible, Albert L. Mcclure

Electronic Theses and Dissertations

Biblical iconoclasm is any biblical text that describes the disruption of religious observances by physical violence against cult materials. This can include removing cult objects from their appointed places, god-napping divine bodies, outright destruction, cult reform, etc. Biblical iconoclasm, understood this way, is one component of the Hebrew Bible’s iconic politics. Other components of biblical iconic politics – like Idol Parodies, Bildersverbot, and aniconism – have been well studied in the past thirty years. Biblical iconoclasm has not shared the popularity of its collaborators in this respect. This dissertation is necessary because no extended study of iconoclasm in the Hebrew …

Rhetorical Genealogy And The Ethics Of Eugenics, David Mark Thomas

Electronic Theses and Dissertations

This dissertation strives to critique contemporary rhetoric on eugenics. In recent years, scientists succeeded in mapping the human genome and subsequently developed new gene editing technologies. To situate current ethical discourses about eugenics, I trace histories of these discourses at several scales of society – from the macroscopic level of the body politic to the meso level where modes of assessment have been deployed purportedly to accurately evaluate human characteristics to the microscopic level of the gene. I employ Foucauldian genealogy to highlight how, despite marked differences over time in specific eugenic discourses and practices exist, the underlying rhetoric has …

Behind The Exhibit: Exploring The Processes Of Indigenous Rights Representation At The Canadian Museum For Human Rights, Madison Caroline Dillard

Electronic Theses and Dissertations

Focusing on the representation of Indigenous human rights at the Canadian Museum for Human Rights (CMHR) in Winnipeg, Manitoba, this study examines how museums can represent, educate, and advocate for Indigenous human rights. The study is based on ethnographic fieldwork carried out at the museum in July 2019 and the literature on anthropology and human rights, decolonizing museum practices, and museums as spaces for human rights dialogue. The study shows how museums can change their history of racist and inaccurate representation of Indigenous people. Through extensive and “deep collaboration” between Indigenous partners and museum staff, Indigenous culture, history, and rights …

The facial features are the most important tool to understand an individual's state of mind. Automated recognition of facial expressions and particularly Facial Action Units defined by Facial Action Coding System (FACS) is challenging research problem in the field of computer vision and machine learning. Researchers are working on deep learning algorithms to improve state of the art in the area. Automated recognition of facial action units has man applications ranging from developmental psychology to human robot interface design where companies are using this technology to improve their consumer devices (like unlocking phone) and for entertainment like FaceApp. Recent studies …

Manifestations: Displays Of Internal Beliefs And Perspectives, Manuel Ferreira

Electronic Theses and Dissertations

This thesis aims at better understanding and sharing the internal beliefs, influences, and insights of specific Field Museum staff in regard to exhibitions and the future of the Field Museum. It is people that make up museums and create exhibitions, and their beliefs not only influence and guide them, but also their institution and what they develop. Grounded in museum anthropology, and framed by new and critical museology, entanglement, contact zones, museum as method, and a queer mezclando (mixing) perspective, this research employs museum ethnography as a way of exploring relations and meanings among museum staff, beliefs, and manifestations. In …

Beyond Interventions: A Case Study Of The Denver Art Museum’S Native Arts Artist-In-Residency Program, Madison Sussmann

Electronic Theses and Dissertations

The Denver Art Museum’s Native Arts Artist-in-Residency Program is an inter-departmental project dedicated to the collaboration between the museum, artists, and visitors. The residency and the physical studio were established to formalize artist involvement in the museum. There is no written mission statement for the program, but visitor engagement is central to the organization of the program and experience of the artist. This thesis explores the question: What can the experiences of the artists and museum professionals involved in the Native Arts Artist-in-Residency program tell about the residency’s contribution to critical museology and decolonization? Through exploring the definitions of critical …
