Because I Said So: The (Re)Production Of White, Ableist Narratives Through Legal Discourse In Endrew F. V. Douglas County Re-1, Stephen F. Fusco

Electronic Theses and Dissertations

As families and advocates of students of color labeled with dis/abilities face mounting inequities they turn to the courts seeking protection. Unfortunately, even after courts issue written decisions ostensibly designed to protect students labeled dis/abled, these students continue to experience systematic oppression in school. This is due, in part, to the discourse used by the courts when addressing issues affecting students labeled dis/abled and the elitism of the judicial system. The purpose of this study was to examine the legal discourse used in the most recent Supreme Court case concerning the education of students labeled dis/abled, Endrew F. v. Douglas …

A hybrid aerial-ground robotic platform allows for enhanced functionality combining most of the operational profiles of an aerial and ground vehicle with applications to intelligence, surveillance, reconnaissance (ISR), infrastructure inspection, emergency response, photography, etc. Motivated by this challenge, we designed, developed, and tested a prototype hybrid aerial-ground robotic vehicle capable of guidance, navigation, and control in the air and on the ground. The thesis focus is on the system design. As such, at first, we designed and analyzed the mechanical component to ensure durability. We then designed the electrical component to reduce overall weight and maximize battery life. We developed …

Airbnb Release Of Latent Economic Value And Return To Equilibrium, Daniel Joseph Trujillo

Electronic Theses and Dissertations

We empirically consider Airbnb’s effect on a new variable in Short Term Rental (STR) research, second homes, employing a model pre-Airbnb diffusion (2009), and post-Airbnb diffusion (2019). In doing so we test our hypothesis that second home use will be converted to short-term rentals with the advent of Airbnb. We do so through a natural experiment examining housing stock. We create a schema to segregate tourist and non-tourist counties based on economic variables and deploy these in our research framework observing a shock to housing supply. Notably, we observe a structural change in the use of second homes resulting in …

Mechanisms Of Sensory Adaptation In The Primate Visual System, Boris Isaac Peñaloza Rojas

Electronic Theses and Dissertations

Under ecological conditions, the luminance impinging on the retina varies within a dynamic range of 220 dB. Stimulus contrast can also vary drastically within a scene, and eye movements leave little time for sampling luminance. In addition, the amount of information reaching our visual system far exceeds the brain’s information processing capacity. Given the limited dynamic range of its neurons and its limited capacity in processing visual information in real-time, the brain deploys both structural and functional solutions that work in tandem to adapt to the surroundings. In this work, employing visual psychophysics and computational neuroscience, we study the mechanisms …

Nucleic Acids Promote Oligomerization Of Immunoglobulin G, Alexa Gomez

Electronic Theses and Dissertations

Nucleic acids have been found to prevent aggregation as chaperones, as well as act as co-factors and promote aggregation of amyloidogenic proteins leading to various diseases. Immunoglobulin G, IgG, are prone to aggregate as therapeutic proteins, and light chains of IgG can form amyloid fibrils, causing a disease known as light chain amyloidosis. Here we discuss the effect nucleic acids have on full-length immunoglobulin G aggregation. Our results show G-quadruplex DNA, and bulk DNA lead to oligomerization of full-length IgG, and induce increases in secondary structure. Tryptophan fluorescence indicates structural changes are occurring in the presence of DNA. Additionally, IgG …

Microfoundations Approach To Risk And Uncertainty In The Uppsala Internationalization Process, John P. Merli

Electronic Theses and Dissertations

This study answers rising calls in International Business to employ a microfoundations approach for greater insight on differences in managerial cognition for entering business in high-risk locations. Consequently, findings challenge the Uppsala model’s longstanding stance concerning the risk-internationalization association governed by strict firm-level analysis. I examine CEO decision-making through the lens of their values, represented by their political ideology score along the liberal-conservative continuum, to offer greater predictability for rationalizing strategic choices. Accordingly, political ideology proved a significant predictor for explaining the circumstances in which CEOs elect high-risk locations based on their political ideology’s degree of liberalism. Additionally, its interactions …

Out Of Time: Temporal Performativity And Resistance In Popular American Film, Television, And Theater, Meghan Johnston Aelabouni

Electronic Theses and Dissertations

This dissertation argues that religious world-making in popular culture can reveal and resist hegemonic times. Taking as my primary case study the United States in the 2010s, particularly the shift from the Obama to the Trump era, I analyze cultural constructions of time—as sacred history, destiny, and “the times”—that reflect and shape national identity and belonging in the American imagined community. In this context, such temporal constructions have privileged whiteness and heteronormative masculinity, positioning those who embody or approximate this norm as “of the times,” while also displacing BIPOC, women, and queer people as “out of time.” I posit time …

Turning The Tempest For God’S Forgotten: Psalm 42 As Synecdochic Lead Of The Elohistic Psalter, David P. Pettit

Electronic Theses and Dissertations

This dissertation’s thesis states Ps 42 is the synecdochic lead of the Elohistic Psalter, arguing for a particular type of literary relationship between Ps 42 and this collection (Pss 42-83). As synecdoche, Ps 42 introduces and represents, in microcosm, the themes, imagery, language, and actuational potential of the collection. The lead psalm becomes a lens that affects what aspects and commonalities come to light in the following psalms. This is not merely an intertextual study, however. This study is situated within psalms studies and the long reach of Gerald Wilson’s work and the Shape and Shaping approach to the Psalter. …

A Biophysical Investigation Of Hiv-1 Envelope Cytoplasmic-Tail Mediated Retention In The Gag Lattice, Nicholas Scott Groves

Electronic Theses and Dissertations

The infectivity of Human Immunodeficiency Virus is critically dependent on successful incorporation of the trimeric viral envelope glycoprotein, Envelope (Env), into Gag lattice assembly sites on the host-cell plasma membrane during virus biogenesis. The mechanistic nature of interaction between Gag, the structural protein, and Env, the viral spike, are dependent on the Gag matrix (MA) and Env cytoplasmic tail (CT) domains. Env laterally diffuses on the host cell plasma membrane until encountering a budding Gag lattice, where it is retained until particle scission and release. The mechanism of Env entry and retention in the lattice remains elusive and enigmatic. Here …

The Effect Of Early Literacy Experiences On Preschool Teachers’ Literacy Approach, Lisa Mcmillan

Electronic Theses and Dissertations

The purpose of this study was to investigate how personal literacy experiences during the early years of three preschool teachers impact the literacy experiences they provide for their students in their preschool classroom. Data was collected using the narrative inquiry method of qualitative research. Two in-depth, open-ended interviews were conducted with three preschool teachers at Hunter Early Learning Center. Questions were asked aiming to learn about the childhood literacy experiences of the teachers and about their approach to literacy as preschool teachers. They were also asked to create aesthetic representations at the end of each interview as an additional source …

The Design, Development, And Determination Of A Virtual Reality Classroom, Victoria Alexxis Reddington

Electronic Theses and Dissertations

The COVID-19 pandemic has radically changed the way students learn and engage with their peers and instructors. Likewise, instructors have had to quickly transform their course materials to suit the online classroom format. Results from a survey of students and instructors at the University of Denver revealed that perceived levels of learning and collaboration were lessened with the transition to online learning. Moreover, the sense of presence in an educational atmosphere with other individuals was reported to be significantly stronger in a real physical classroom, as compared to an online classroom. This thesis therefore seeks to provide a new, alternative …

Database Of Picture-Based Cognitive Reappraisal Experiments: Analyses Of Trial-Level Factors, Damon Abraham

Electronic Theses and Dissertations

Cognitive reappraisal is widely recognized as an effective emotion regulation strategy for managing negative emotions. In laboratory research, reappraisal has been shown to attenuate self-reported negative affect as well as physiological and neurological markers of emotion and arousal. In these experiments, emotionally evocative images are frequently used to induce negative affect in participants. Depending on the trial condition, participants are instructed to either look and react naturally or to change their experience using reappraisal. Data are typically aggregated within trial condition, and the average difference in reported negative affect between conditions serves as the behavioral measure of reappraisal success. While …

Optimized Microbial Recombinant Production Of Hiv-1 Anti-Envelope Antibody Fragments With Applications To Single Particle Tracking Of Virus Assembly, Merissa Michelle Bruns

Electronic Theses and Dissertations

In my findings, I have established a set series of protocols to recombinantly produce, purify and apply various fluorescent probes in vitro for the fluorescent labeling and study of the human immunodeficiency virus type 1 (HIV-1) envelope (Env) protein during HIV viral assembly. There remains insufficient knowledge about the molecular dynamics and interactions of HIV-1 Env protein with its counterpart, Gag, on the inner host cell surface during assembly of a mature virus particle. There also remains an insufficient amount of data for the understanding and clarification of the mechanism of action of a known host cell HIV-1 restriction factor, …

Criminalized Houseless Women, Jesus, And The Praxis Of Kinship: An Outsider’S Liberative Ethic, Sarah A. Neeley

Electronic Theses and Dissertations

Criminalization measures, such as Denver’s Urban Camping Ban, are an attempt to mask systemic causes of houselessness and assign blame to the personal failures of those living on the streets. Unaccompanied houseless women utilize street families to create community, survive houselessness, and fight criminalization measures. Since liberation and solidarity can become forces of oppression, this dissertation considers cultural evidence for the desire and means of liberation. Street families and the praxis of kinship form the basis of a liberative ethic that critiques systemic causes of houselessness and provides a model of relatedness that works toward social justice. The project is …

Deep Learning Methods For Fingerprint-Based Indoor And Outdoor Positioning, Fahad Alhomayani

Electronic Theses and Dissertations

Outdoor positioning systems based on the Global Navigation Satellite System have several shortcomings that have deemed their use for indoor positioning impractical. Location fingerprinting, which utilizes machine learning, has emerged as a viable method and solution for indoor positioning due to its simple concept and accurate performance. In the past, shallow learning algorithms were traditionally used in location fingerprinting. Recently, the research community started utilizing deep learning methods for fingerprinting after witnessing the great success and superiority these methods have over traditional/shallow machine learning algorithms. The contribution of this dissertation is fourfold:

First, a Convolutional Neural Network (CNN)-based method for …

The Relationship Between The Supervisory Alliance And Novice Supervisees’ Risk-Taking Behavior, Aleis Pugia

Electronic Theses and Dissertations

Supervisee risk-taking is the process by which supervisees take the new skills and interventions they learn in supervision and implement them in therapy with clients. Risk-taking overlaps with many of the skills supervision is intended to develop: clinical decision-making, supervisee self-efficacy, supervisee skill development, and clinical reflection (Bambling & King, 2014; Ellis et al., 2014; Rousmaniere et al., 2016; Wilson et al., 2016). Risk-taking has not been examined before the in the supervision literature, however, it is an important process to understand as it represents a process bridging supervision and clinical practice. The current study was an exploratory study intended …

The combined revenue stream was found to produce the most revenue …

Biased Technical Change, Institutional Shift, And The Functional Distribution Of Income: Who Benefits From Economic Growth?, Adam Szymanski-Burgos

Electronic Theses and Dissertations

Starting from the mid 1970s and early 1980’s, the US and other advanced economies observed a widening divergence between the growth of average and median real hourly labor compensation and the average growth of labor productivity. This decoupling between labor compensation and productivity indicates a decline in the labor share of national income. Opposite to movements in the labor share, the share of national income remunerated as capital income has increased with the rise of capital incomes concentrated largely in corporate sector profits. Key developments since the middle of the 20th century have coincided with the onset of medium-run fluctuations …

The Great Consensus After The Great Recession: The Case Of Jamaica, Anthony N. Iacovelli

Electronic Theses and Dissertations

The purpose of this research was to determine the efficacy of the International Monetary Fund’s Stabilization Program (IMFSP) as a tool for economic development. The Fund’s program utilizes an approach steeped in the Washington Conesus, which requires austere and demand side economic measures to be taken to achieve success. To determine efficacy, Jamaica was used as a case study, where special attention paid to the supply side economic consideration of human capital development in Health and Education. Additionally, this paper contrasted the IMF approach with a case study of Singapore and the Developmentalist approach to economic development. The research provided …

The Martyr’S Desire: Levinas, Girard, And Infinite Responsibility, Joshua Alan Lawrence

Electronic Theses and Dissertations

Perhaps the whole of human history could be summed up with one word: economy. The law of the home and the home of all law. Without fail, this situation results in a structured devotion that must decide what to do with desire. And the economic decision often follows a violent trajectory, most commonly described as sacrifice. Today, states will make efforts to conceal this underlying logic, but the insidious configurations of ‘real politik’ usually surface with a frightening intensity.

My project considers these problematic vestiges through Emmanuel Levinas’s reconfiguration of subjectivity. To address these bio-historical realities, my work highlights the …

Education is a human right, and equal access to education is not only crucial for an individual’s well-being, but also essential for eradicating poverty, ensuring long-term prosperity for all, transforming the society, and achieving sustainable development. Measuring education development, especially the variations of educational attainment, in a timely and accurate manner can help educators, practitioners, scientists, and policymakers compare and evaluate various education indicators at both subnational and national levels. This research presents an approach that combines multi-source and multidimensional data including population distribution, human settlement, and education data to assess and explore educational attainment trajectories at both national and …

We All Want To Change The World: How Behavioral Insights Can Help Reduce Carbon Emissions, Thomas C. Gifford

Electronic Theses and Dissertations

The world is in the midst of an unprecedented environmental crisis driven primarily by human behavior. As the world has globalized, countries have developed, and standards of living have improved, global pollution has skyrocketed and has resulted in a wide range of environmentally destructive outcomes. All paths to environmentally sustainable development involve a dramatic cut in carbon emissions from current day levels. In this thesis, I explore how the omission of behavioral factors from mainstream neoclassical models has contributed to, and can aid in reducing unsustainably high levels of carbon emissions. Throughout the history of economic thought, classical economists such …

Compressible Hydrodynamics Of Few Body Optical Vortices, Jasmine M. Andersen

Electronic Theses and Dissertations

The ubiquity of vortices nearly rivals that of the innumerable fluids and spaces in which they live. Not only do they exist in systems such as superfluids, superconductors, optical fields, or cold atomic gases, for example, but they also exist in our atmospheres, oceans, and even in our veins. This makes understanding and accurately predicting the dynamics of vortices in various systems a relevant and meaningful endeavor.

From a typical hydrodynamic perspective, vortices move within a given fluid because of the background fluid density and phase gradients at the vortex location. However, we find that these gradients alone are insufficient …

Engagement And Development Of Professional Skills Among Low-Income, High-Achieving Students: A Structural Equation Model, Nasser Alresaini

Electronic Theses and Dissertations

This dissertation tested the effect of academic engagement and social engagement on developing soft professional skills for low-income, high-achieving students in higher education. Using the publicly available data of GMS scholarship, the analysis was consisted of EFA and SEM. The general effect model gave a general idea about the tested population, whereas the conditional model highlighted the groups' specific significance. Low-income, high-achieving students continued their academic and social engagement growth during their school years. Academic engagement positively enhanced students' soft professional skills for students who did not receive the GMS scholarship, students from educated and uneducated parents, Asian and Hispanic …

Resentenced And Released: Re-Entry Needs Following Release From Juvenile Life Without Parole, Daphne M. Brydon

Electronic Theses and Dissertations

Over 2,100 individuals serving juvenile life without paroles (JLWOP) sentences in the U.S. became eligible for resentencing following the 2016 Montgomery v. Louisiana Supreme Court ruling. Michigan housed an estimated 370 juvenile lifers at that time, the second largest JLWOP community in the country and has since resentenced and released approximately 120 juvenile lifers. Folx released from prison encounter many barriers to successful re-entry. Barriers are often amplified for those incarcerated as adolescents. Further, services are de-prioritized for folx serving JLWOP sentences, which can be especially damaging for this community whose life experiences are marked by high rates of trauma, …

Undergraduate Teaching Excellence Through The Aesthetic Lens Of Crispa, Paula Adamo

Electronic Theses and Dissertations

In times where only 60% of college students are graduating (NECS, 2018), the need to help undergraduates thrive in college is vital. Because faculty have a crucial role in this profound endeavor, this study examines the intentions (intentional curriculum) of four undergraduate instructors identified by colleagues and students as good teachers. The study also examines what students take away from their instructors and classes (received curriculum) and looks at how elements of the aesthetic approach to teaching and learning known as CRISPA emerge naturally in the curricula in order to demonstrate the proposition that good teachers, at any level, implement …

Evaluating Nuclear Energy As A Component Of U.S. Energy Innovation Systems, Bryce Jones

Electronic Theses and Dissertations

Nuclear energy is contentious in policy discussions that evaluate its role in the current U.S. clean energy innovation system. OECD nations, on average, have begun to reduce their dependence on nuclear energy. However, the United States has remained invested in its nuclear energy infrastructure and the role that it plays within federal research and development. This thesis examines the Neo-Schumpeterian perspective and the National Innovation System’s approach, the economic history of nuclear energy in the United States, and given insight from these factors, discusses the current role of nuclear energy in the U.S. energy innovation system. The objective is to …

Demystifying School Resource Officers: A Case Study, Alexis Sliva

Electronic Theses and Dissertations

In recent years, there has been a dramatic spike in student arrests for behaviors that previously fell under the auspices of suspensions, expulsions, or family consultations. Black and Latinx students receive discipline and law enforcement referrals at superfluous levels compared to White peers. Additionally, the disproportionate and aggressive referral of Black, Indigenous, and People of Color (BIPOC) students for disciplinary action are often for infractions that are considered less severe than the actions of their White counterparts. Punitive discipline advances school-based pathways to the juvenile justice system (SPJJ), formerly known as the school to prison pipeline (STPP). School psychologists are …

A Grounded Theory Inquiry Into The Pedagogical Socialization Of Graduate Students Within Graduate Quantitative Methods Courses, Amanda Kay Thomas

Electronic Theses and Dissertations

Quantitative methods are one of the most highly technical fields of study within social sciences graduate programs. Although classroom pedagogy is an important factor connected to student success within graduate quantitative methods courses little is known on the pedagogical socialization experiences of masters and doctoral students. The purpose of this grounded theory inquiry was to discover graduate students perspectives on their pedagogical socialization experiences and the norms, values and role expectations transmitted during the teaching and learning of quantitative methods. Narrative data was collected from in-depth interviews among a theoretical sample of 31 masters and doctoral students enrolled in introductory, …
