Dissertations and Theses
La Cofradía de Artes y Artesanos Hispánicos: Redefining Tradition in the New Mexican Art Market. May 2019.
This master’s thesis explores the 1978 founding, existence, dissolve, and the legacy of the Santa Fe, New Mexican artist exhibition group, La Cofradía de Artes y Artesanos Hispánico (La Cofradía). La Cofradía was formed by six Santa Fe Hispano artists in reaction to creative limitations first imposed on Hispano artists in 1926, when the annual Spanish Market was formed. The Spanish Market was the sole arts sales venue available to Hispano artists in the exclusionary Santa Fe gallery and museum market. The Spanish …
Multi-Locus Phylogenetic Inference Of The Howler Monkey (Alouatta) Radiation In South America., Esmeralda Ferreira
Multi-Locus Phylogenetic Inference Of The Howler Monkey (Alouatta) Radiation In South America., Esmeralda Ferreira
Dissertations and Theses
Abstract
Howler monkeys (Alouatta) are the most widely distributed New World primates, ranging from southern Mexico to northern Argentina. They occur in tropical rain forests, flooded and gallery forests, and deciduous and semi-deciduous environments. Despite their importance as seed dispersers, howlers have also been known to be ecological indicators. Available phylogenetic hypotheses for this genus have used chromosomal characters, morphological characteristics, and a limited number of molecular markers and specimens. In spite of these analyses, branching patterns among howler species lineages conflict between studies or remain unresolved. Using 14 unlinked non-coding intergenic nuclear regions under both a concatenated …
Pressure, Temperature, And Stress Conditions Of Southern Alpine Fault (New Zealand) Mylonites, Jake T. Reitman
Pressure, Temperature, And Stress Conditions Of Southern Alpine Fault (New Zealand) Mylonites, Jake T. Reitman
Dissertations and Theses
The Alpine Fault, New Zealand, provides a unique window into the rheologic history of a seismically-active continental plate boundary. Due to lower exhumation rates along southern portions of the fault relative to the well-studied central Alpine Fault, deformation ages vary along strike by ~15 m.y.. Mylonites collected from two southern creeks near Haast, NZ, display a uniform recrystallized grain size of ~11 𝜇m in mylonitic quartz indicating differential stress values in the south of ~100 MPa, roughly twice the stress values observed in the central Alpine Fault. Constraints from Ti-in-quartz thermobarometry and Raman Spectroscopy of Carbonaceous Material (RSCM) indicate mylonitization …
An Overview And Evaluation Of Synthetc: A Statistical Model For Extra-Tropical Cyclones, Rafael Uryayev
An Overview And Evaluation Of Synthetc: A Statistical Model For Extra-Tropical Cyclones, Rafael Uryayev
Dissertations and Theses
Extratropical cyclones (ETCs) are the most common weather phenomena affecting the United States, Canada, and Europe. They can pose serious hazards over large swaths of area. In this thesis, a statistical model of ETCs, called SynthETC, is discussed. The model accounts for the for genesis, track path, termination, and intensity of statistically generated ETCs. Genesis is modeled as a Poisson process, whose mean is determined by climate and historical information. Tracks are modeled as a regression-mean determined by climate and historical information plus a stochastic component. Lysis is modeled using logistic regression, with climate states as covariates. Intensity is modeled …
Comparison Of Gold Extraction Yields By Cyanide Treatment Vs. Bioleaching Procedure, Yilman Steven Pineda
Comparison Of Gold Extraction Yields By Cyanide Treatment Vs. Bioleaching Procedure, Yilman Steven Pineda
Dissertations and Theses
Samples from the tailings of the Picacho mine in California were leached using NaCN and native bacteria, Alcaligenes faecalis, in column experiments to compare the gold recovery yields in the effluents. Four columns were treated with a different liquid: water, bacteria, NaCN and a mixture of cyanide and bacteria. After they were leached the effluents were analyzed to determine gold yields. During experiment I the total Au recovered in the effluent in the column treated with bacteria was only 10.09% less than those treated with cyanide (C2) and 81.7% more than the control. In experiment II, Au values measured were …
Snowmelt Detection On Alpine Glaciers Using Synthetic Aperture Radar Time Series, Corey Scher
Snowmelt Detection On Alpine Glaciers Using Synthetic Aperture Radar Time Series, Corey Scher
Dissertations and Theses
Hindu Kush Himalayan (HKH) glaciers serve as some of the most sensitive indicators of changes in global climate. These glaciers shape the hydrologic dynamics of river systems supplying freshwater to over 2 billion people throughout Asia and regulate the geochemistry of sensitive aquatic alpine ecosystems. As snowmelt onsets sooner, lasts longer, and snowfields retreat due to increases in global temperature, the hydrologic dynamics of catchments draining HKH threaten to change the availability of surface freshwater resources for nearly one fifth of the global population, disturb sensitive aquatic habitat, and precipitate hazards associated with glacier wasting. Informed planning and decision-making around …
Neuron-Glial (Ng) Interactions: A Microfluidic Examination Of Ng Emergent Responses For Repair, Tanya Singh
Neuron-Glial (Ng) Interactions: A Microfluidic Examination Of Ng Emergent Responses For Repair, Tanya Singh
Dissertations and Theses
Neuron-glia communication is crucial to the development, plasticity, and repair of the nervous system (NS). While neurons are well known to conduct electrical impulses that transfer biological information and stimuli throughout the NS, our understanding of the roles of glia continues to evolve from when the cells were largely believed to act solely for neuronal support. Recent decades of research has shown that glia can alter metabolism, conduct impulses and change phenotype for NS repair. NG interactions have, thereby, become heavily researched in varied areas of biomedical engineering, including embryogenesis, neural regeneration, growth, and intracellular synaptic activity. However, while NG …
Controlled Migration Of Retinal Progenitor Cells Within Electro-Chemotactic Fields, Shawn Mishra
Controlled Migration Of Retinal Progenitor Cells Within Electro-Chemotactic Fields, Shawn Mishra
Dissertations and Theses
Vision loss in retinal degenerative diseases is overwhelmingly attributed to damage and death of retinal photoreceptor cells. Studies in mouse retina have suggested that transplantation of isolated post-natal or stem cell-derived retinal progenitor cells (RPCs) to replace apoptotic or damaged photoreceptors may be a novel approach to restore vision. Thus far, outcomes project that the amount of restored visual response depends upon the migration of transplanted cells from insertion in the sub-retinal space to the outer nuclear layer (ONL). However, transplantation efficiency is exceedingly low – ~5% cells transplanted enter the retina – directly limiting the efficacy of the treatments. …
Translational Modeling Of Non-Invasive Electrical Stimulation, Dennis Quangvinh Truong
Translational Modeling Of Non-Invasive Electrical Stimulation, Dennis Quangvinh Truong
Dissertations and Theses
Seminal work in the early 2000’s demonstrated the effect of low amplitude non-invasive electrical stimulation in people using neurophysiological measures (motor evoked potentials, MEPs). Clinical applications of transcranial Direct Current Stimulation (tDCS) have since proliferated, though the mechanisms are not fully understood. Efforts to refine the technique to improve results are on-going as are mechanistic studies both in vivo and in vitro. Volume conduction models are being applied to these areas of research, especially in the design and analysis of clinical montages. However, additional research on the parameterization of models remains.
In this dissertation, Finite Element Method (FEM) models of …
Janus Particles At The Air-Water Interface: Single Particle Behavior, Particle-Laden Interfaces, And Implications For Self-Assembly, Ellen Knapp
Dissertations and Theses
Recent advances in fabrication techniques have allowed for the synthesis of anisotropic Janus particles with precise control of the wetting properties on each hemisphere. Interfacial assembly of Janus particles is of particular interest as the anisotropy and amphiphilicity of these particles can be tuned in order to drive self-assembly and thus be used to template microstructures in a bottom up fashion. The ability to pattern particles at interfaces has a multitude of applications such as achieving films with tunable optical properties, making antireflective surfaces, improving the resolution of E-paper displays and creating water repellant materials. Furthermore, anisotropic particles at interfaces …
Characterizing Chromosomal Aberrations In Cells Deficient For Both Atm And Msh2, Yeliz Inalman
Characterizing Chromosomal Aberrations In Cells Deficient For Both Atm And Msh2, Yeliz Inalman
Dissertations and Theses
Ataxia telangiectasia mutated (ATM) and mutS homologue 2 (MSH2) are important DNA repair proteins that participate in DNA repair pathways to maintain genomic integrity. Mice deficient for ATM and MSH2 mice are viable. However, ATM-/- mice show growth retardation, neurological defects, and spontaneous lymphomagenesis. MSH2-/- mice suffer from aggressive lymphoid tumors between two to five months of age and have increased microsatellite instability, which predisposes MSH2-/- mice to carcinomas. However, mice deficient in both ATM and MSH2 are unable to survive beyond postnatal day 21 (P21). The observed lethality in ATM-/-MSH2-/- mice may result …

Role Of Moa-1, An Anti-Phosphatase, And Apl-1, An App-Related Protein, In Morphogenesis And Mating Behavior In Caenorhabditis Elegans, Valerie C. Moscoso
Dissertations and Theses
Alzheimer's disease is a neurodegenerative disease that affects more than 30 million people globally. The disease is characterized by an accumulation of extracellular beta-amyloid peptide plaques and intracellular neurofibrillary tangles in the brain. The beta-amyloid peptide is derived from a larger precursor protein, the amyloid precursor protein (APP). Mutations in APP have been correlated with Alzheimer's disease. Due to the presence of two paralogues, APLP1 and APLP2, which have overlapping functions, the normal function of APP is difficult to elucidate. Knockout of the entire APP gene family in mice results in lethality and developmental defects, indicating that the APP gene …

Do Saproxylic Curculionids Affect The Fitness Of Co-Occurring Cerambycids?, Sheila R. Heath
Do Saproxylic Curculionids Affect The Fitness Of Co-Occurring Cerambycids?, Sheila R. Heath
Dissertations and Theses
Saproxylic insects sometimes coexist in incredibly high numbers under bark and share common resources. Thus, interactions between species are possible and could even explain their coexistence. This study investigates evidence of negative or positive effects of curculionid beetles (Coleoptera: Curculionidae) on cerambycid beetles (Coleoptera: Cerambycidae) that coexisted in dead tree branches in Costa Rica. Co-occurrence analysis and generalized regressions were used to test associations between cerambycid and curculionid species. Three cerambycid species that each co-occurred with a curculionid species were selected to measure fitness. Fitness measures of the cerambycid were compared with abundance of the co-occurring curculionid to assess the …

Ict-Enabled Control And Energy Management Of Community Microgrids For Resilient Smart Grid Operation, Mahmoud Saleh
Ict-Enabled Control And Energy Management Of Community Microgrids For Resilient Smart Grid Operation, Mahmoud Saleh
Dissertations and Theses
Our research has focused on developing novel controllers and algorithms to enhance the resilience of the power grid and increase its readiness level against major disturbances.
The U.S. power grid currently encounters two main challenges: (1) the massive and extended blackouts caused by natural disasters, such as hurricane Sandy. These blackouts have raised a national call to explore innovative approaches for enhanced grid resiliency. Scrutinizing how previous blackouts initiated and propagated throughout the power grid, the major reasons are lack of situational awareness, lack of real-time monitoring and control, underdeveloped controllers at both the transmission and distribution levels, and lack …
Reframing As Reclamation: Trauma Theory, African Spiritualism, And Ecocriticism In Jesmyn Ward’S Sing, Unburied, Sing, Alexandra Cohl Ms.
Reframing As Reclamation: Trauma Theory, African Spiritualism, And Ecocriticism In Jesmyn Ward’S Sing, Unburied, Sing, Alexandra Cohl Ms.
Dissertations and Theses
This thesis explores how ecocriticism and trauma theory intersect within Jesmyn Ward’s novel Sing, Unburied, Sing (2017) to tackle the complex act of collective healing. Trauma, and its subset transgenerational trauma, have often been a focal point for critical analysis of other African American texts that engage with ghosts and hauntings, such as Toni Morrison’s Beloved (1987). Often, these ghosts are symbolic of transgenerational trauma in fictional works. While this association is apparent in Ward’s novel, this thesis applies the aforementioned modes of scholarship alongside African-based spiritualism to investigate further the inclusion of ghosts. To accomplish this approach, this thesis …
The Embodiment Of Theory In Maggie Nelson's The Argonauts, Julie A. Ficks
The Embodiment Of Theory In Maggie Nelson's The Argonauts, Julie A. Ficks
Dissertations and Theses
The purpose of this research is to explore how Maggie Nelson, in her groundbreaking memoir The Argonauts (2015), works to bring critical theory (primarily queer and feminist theory) out of the academy and into the realm of the personal, rendering theory as tangible and embodied in a real-world setting. Through this unique exchange, Nelson radically reinstates norms relating to gender, sexuality, motherhood and relationships.
Suffering And The Black Female Narrative In The Twentieth Century, Aquilah Jourdain
Suffering And The Black Female Narrative In The Twentieth Century, Aquilah Jourdain
Dissertations and Theses
Adventure, romance, and happiness are not large parts of the stories Black women tell. If we had to name ten mainstream literary novels released in the last 50 years that featured Black women central to the plot — and included the aforementioned themes — we would be hard-pressed to find them. Though there are real life accounts of love, joy, and adventure in the lives of Black women, why do we see these life experiences documented sparingly? In the stories written by andforBlack women, where can Black female readers find joy in their history and culture without elements of grave …

Deconstructing Language Ideologies With Self-Reflective Writing In An Efl Classroom In Haiti: A Critical Discourse Analysis Case Study, Javid Buchanan
Deconstructing Language Ideologies With Self-Reflective Writing In An Efl Classroom In Haiti: A Critical Discourse Analysis Case Study, Javid Buchanan
Dissertations and Theses
This paper draws on data collected from a critical self-reflective writing workshop series within an English as a Foreign Language (EFL) classroom in The Republic of Haiti. This Critical Discourse Analysis (CDA) case study investigates 7 students’ critical self-reflection writing to uncover language-related ideologies embedded within the meaning-making experiences of multilingual language users at a community-based organization. Although students generally show positive or negative attitudes towards language, the use of critical classroom discourse allows students to move beyond generic positive and negative framing when talking about language. Using Gardner’s L2 learner motivation model, this case study explores “instrumental” and “integrative" …
Carbonatites As A Record Of The Carbon Isotope Composition Of Large Igneous Province Outgassing, Ellen Gales
Carbonatites As A Record Of The Carbon Isotope Composition Of Large Igneous Province Outgassing, Ellen Gales
Dissertations and Theses
Large igneous province (LIP) eruptions have been linked in some cases to major perturbations of Earth’s carbon cycle. However, few observations directly constrain the isotopic composition of carbon released by LIP magmas because carbon isotopes fractionate during degassing, which hampers understanding of the relative roles of mantle versus crustal carbon reservoirs. Carbonatite magmatism associated with LIPs provides a unique window into the isotopic systematics of LIP carbon because the majority of carbon in carbonatites crystalizes rather than degassing. Here, we present new δ13C data for the Guli carbonatites in the Siberian Traps. In addition, we compile ~260 published …

This thesis evaluates youth representation within decision-making processes at the national and international levels. It comprises seven chapters that analyze the current narrative of inclusive participation of young people from international organizations, national governments, scholars, and independent institutions. Initially, this work considers the questions of …
The Mediterranean Crisis, Zuzana Turakova
The Mediterranean Crisis, Zuzana Turakova
Dissertations and Theses
A massive European immigration crisis began in 2015, resulting in over a million people flooding into Europe, fleeing conflict and economic desperation. European countries felt threatened by this sudden influx of people who either looked different or practiced different religions, and this caused a major backlash in these predominantly Christian countries. Anti-immigrant fever has changed the political environment in Europe and as a result, most EU policies today focus on preventing migrants from reaching European borders. In this thesis, I argue that the paucity of knowledge and lack of preliminary communication and pre-warning on the scale of the Mediterranean crisis …
