Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …

Fighting Words: Slurs, Semantics, And The Law, Richard Stillman

Dissertations, Theses, and Capstone Projects

Oppressive slurs like the n-word are fighting words par excellence. Their power to incite conflict and inflict emotional injury is unmatched by that of other, more commonplace insults. But what is it that makes oppressive slurs such potent verbal weapons? A commonplace view among both philosophers and legal theorists is that slurs make such potent insults because their uses convey extremely offensive, bigoted attitudes. This dissertation argues that this view is mistaken, and that its falsity has important implications for hate speech jurisprudence. I argue that, to grasp what makes slurs such potent verbal weapons, we ought conceive …

Beyond Authorization: Toward Abolitionist Transliteracies Ecologies And An Anti-Racist Translingual Pedagogy, Lindsey Albracht

Dissertations, Theses, and Capstone Projects

This project explores the recent paradigm shift within Writing Studies toward a translingual pedagogical approach, situating many of the critiques of this approach as limitations produced by dominant liberal models of Writing Studies pedagogy.

Taking up Vershawn Ashanti Young and Frankie Condon’s call to move toward a more anti-racist translingual approach, I argue for why dominant anti-racist Writing Studies pedagogies, which commonly revolve around reforming individual behaviors, attitudes, dispositions, or practices, will inadequately address institutionally-produced structures of racialized linguistic marginalization.

Drawing inspiration from a variety of Lefist abolitionist movements—particularly the movement toward Prison Industrial Complex (PIC) abolition, the movement toward …

Mother’S Understanding Of The Newborn Infant Hearing Screening (Nihs) And The Audiologist’S Role In Healthy Hearing, Chaya T. Ungar

Dissertations, Theses, and Capstone Projects

The Newborn Infant Hearing Screening (NIHS) is a process mandated by the state, which requires that all children born in New York must receive a hearing screening at birth and prior to discharge. The NIHS enables the early identification and subsequent treatment of hearing loss in infants. To properly facilitate identification, the infants who fail the screening are referred for further testing either to confirm normal hearing at the time of the screen or to identify the extent of the hearing loss, if one is found to exist. An additional way, dictated by New York State, in which early identification …

The Linknyc Kiosk: Phone Booths, Urban Culture, And The Neoliberal Dream For New York City, Michael A. Villanova

Dissertations, Theses, and Capstone Projects

This thesis provides a history of the development policies around the phone booth in New York City as a “dialectical image” to understand the use of urban culture as a means of achieving political ends. First, I lay out a cultural history of public communication devices in their relation to the political and material changes in New York City since the late 19^th century. By doing so, this thesis explains how the cultural significance of the phone booth opens essential points of connection between notions of autonomy, uses of technology in the public sphere, and the relation between politics …

Applying Deep Learning On Financial Sentiment Analysis, Cuiyuan Wang

Dissertations, Theses, and Capstone Projects

Portfolio Investment has always been appealing to investors and researchers. In the past, people tend to use historical trading information of the securities to predict the return or manage the portfolio. Nowadays, the literature has been proved that the market sentiment could predict asset prices. Specifically, it has been shown that the stock market movement is related to financial news and social media events. Thus, it becomes necessary to extract the sentiment of the financial news. We explicitly introduce the application of dictionary methods, traditional machine learning models and deep learning models on text classification. The experiment results show that …

Targeting Ampa Receptor Modulation During Early Life Adversity: A Mediator For Threat Associated Memories, Roseanna M. Zanca

Dissertations, Theses, and Capstone Projects

Early life adversity (ELA) is the exposure to a single or to multiple traumatic events before the age of 18 that go beyond the child’s coping. These adverse events are often exacerbated during adolescence particularly when cognitive performance is compromised. Adolescents who experienced ELA may show symptoms of post-traumatic stress disorder (PTSD), while not vividly recalling the early life trauma. These individuals show atypical connectivity between prefrontal-amygdala and hippocampus, all of which is associated with an increased risk of experiencing a traumatic event again later in life. While clinical research has increasingly stressed the importance in addressing the long-lasting consequences …

Toward The Black Indian Ocean: Race And The Human Project In The Afro-Asian Imagination, Micheal A. Rumore

Dissertations, Theses, and Capstone Projects

“Toward the Black Indian Ocean: Race and the Human Project in the Afro-Asian Imagination” asks the question: why hasn’t the Indian Ocean been typically theorized as an African diasporic site? While the burgeoning discipline of Indian Ocean studies frequently positions notions of oceanic “cosmopolitanism” as a way of engaging with universalist anticolonial aspirations, the field has been limited by static conceptions of the African continent. In response, this dissertation argues that the marginalization of Black Africans in conceptions of Indian Ocean cosmopolitanism reflects a colonial provenance and attempts to delineate this representational history. Theoretically, I engage with Black feminist critiques …

El Pueblo Unido: How Threats Increased Latinx Turnout In Arizona’S 2020 General Election, Conner Martinez

Dissertations, Theses, and Capstone Projects

Latinx voter turnout in the United States has persisted to remain below White, Black, and Asian Americans. In 2020, county level data shows Latinx turnout reached historic levels in Arizona’s 2020 general election (Pew Research 2020; Census 2020). But throughout the past two decades, Latinx’s in Arizona have faced some of the harshest anti-immigrant policies in the nation. Currently, the literature on Latinx mobilization shows mixed results on the impact of political threats on Latinx turnout (Jones-Correa et al. 2018). Through in depth interviews with Latinx organizational leaders who managed mass mobilization efforts in 2020, this paper explores the role …

Optimization Of Materials For Magnetic Refrigeration And Thermomagnetic Power Generation, Anthony N. Tantillo

Dissertations, Theses, and Capstone Projects

The magnetocaloric effect, by which a magnetic material experiences a change in temperature due to an applied magnetic field, can be used for refrigeration. The corollary to the magnetocaloric effect -- known as the pyromagnetic effect -- is the phenomenon by which a magnetic material experiences a thermally-induced change in magnetization that can be used to harvest thermal energy. This dissertation has two main parts: one focusing on novel materials for energy harvesting; and another focusing on methods of materials discovery for refrigeration purposes. Thermomagnetic power generation (TMG) is the process by which magnetic flux, which comes from a temperature-driven …

Everyone Is Watching: Mastering The Challenge Of Caring For Infants At The End Of Life While Being Constantly Observed, Deborah A. Lawrence

Dissertations, Theses, and Capstone Projects

Nurses with specialized training care for the approximately 7% of newly born infants who are admitted annually to neonatal intensive care units in the United States. Although they receive care at advanced levels, some infants will not survive. Nurses maintain a constant presence at the bedsides of these neonates to provide end of life care in units and institutions where the gold standard is cure and rescue. The purpose of this grounded theory research study was to understand how nurses managed the challenges and demands of caring for dying infants in the context of Level III neonatal intensive care units. …

The Integration Of Art, Architecture, And Identity: Alfred Kastner, Louis Kahn, And Ben Shahn At Jersey Homesteads, Daniel S. Palmer

Dissertations, Theses, and Capstone Projects

During the New Deal, the United States government created the Jersey Homesteads co-operative in order to help a group of Jewish immigrant garment workers from New York City during the economic downturn of the Great Depression. This dissertation examines how a 1930s utopian enclave utilized modernist art and architecture to express the radical back-to-the-land agrarian idealism and socialist ideology of its settlers. The flat-roofed, concrete buildings that housed these Jewish garment workers were designed by German architect Alfred Kastner (1900-1975), with his then unknown assistant Louis I. Kahn (1901-1974). These unornamented, functionalist buildings adapted avant-garde European architectural forms into an …

Developing Supramolecular Tripeptides With Sequence Tunable Visible Absorbance And Emission, Mona Tayarani Najjaran

Dissertations, Theses, and Capstone Projects

The structure and machinery of living systems are based on sequence-specific peptides that are composed of just 20 amino acids. The supramolecular assembly of peptides is a result of weak non-covalent forces among the amino acid residues that lead to diverse ordered structures and properties. Rational peptide design with sequence-specific combination of the 20 genes encoded amino acids is a promising new route for the production of materials with new functional properties. Aromatic residues have been shown an important role in self-assembly through increasing the aggregation possibility. They also have shown fluorescence properties in the ultraviolet range. In this thesis …

Microbial-Host Dynamics And The Evolution Of Nearshore Diversity In Hippocampus Abdominalis, Jimiane L. Ashe

Dissertations, Theses, and Capstone Projects

Local adaptation is a fundamental concept at the core of evolutionary process. Devising means to break down larger concepts and systematically test internal mechanisms are key to understanding the driving forces behind the influence of environmental differences on biological systems. To understand dynamic processes in the natural world, we must strip away layers and confounding variables that may mask the signal we hope to understand. In this case seahorse species, Hippocampus abdominalis, or the pot-bellied seahorse, made an unlikely but ideal study system. The first layer to strip away was neutral genetic variation within the population. A multilocus genetic …

Neuroplasticity Of The Corticospinal System: Applications Of Neuromodulation-Based Therapies, Alzahraa M. Amer

Dissertations, Theses, and Capstone Projects

The motor cortex and corticospinal tract are necessary for producing skilled movements. I use intermittent theta burst stimulation (iTBS), a high-frequency stimulation protocol known to promote neural plasticity, as a tool to characterize short- and long-term plasticity of the CS system.

Although it is well known that activity-dependent motor cortex (MCX) plasticity produces long-term potentiation (LTP) of local cortical circuits, leading to enhanced motor evoked potentials (MEPs), the effects produced by the corticospinal (CS) projection on spinal cord neurons have not yet been thoroughly studied. In Chapter 2, I determined if the CS tract (CST) is capable of producing LTP …

Optimism Of The Intellect, Pessimism Of The Will? A Gramscian Analysis Of Two New York Police Reform Campaigns, Christian Covington

Dissertations, Theses, and Capstone Projects

This paper attempts to analyze two recent New York police reform campaigns - one to overturn the state’s system of criminal bail release, the other to make police officer discipline transparent to the public - using theories given by Antonio Gramsci. The paper will apply the concepts of hegemony, hegemonic discourse, the intertwining of the state and civil society, the attainment of political agency amongst the subaltern, and the role ideology plays in all of these concepts, to assess the success of the reform campaigns. The paper will argue that many of these concepts are further developments of political theories …

Functional Connectivity Changes In The Default Mode Network In Moderate-To-Severe Traumatic Brain Injury, Emily J. Haight

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) patients are known to have altered functional connectivity (FC), which has cognitive and behavioral significance and bears clinical implications. Previous literature has discovered a hyperconnectivity response to TBI, most notably in the default mode network (DMN). However, the exact pattern of changes in resting FC during the first year of recovery is unknown. We used resting-state functional magnetic resonance imaging to investigate longitudinal connectivity patterns in the DMN of 28 moderate-to-severe TBI patients as compared to 33 demographically matched healthy controls (HC). FC was assessed at 3, 6, and 12 months post-injury for patients using the …

On The Woman Question: A Defense Of Alexandra Kollontai Against Liberal Critics, Nicole Baltzer

Dissertations, Theses, and Capstone Projects

Alexandra Kollontai envisioned a world in which all women and their proletarian comrades were liberated from subordination under capitalism. She served as People’s Commissar in the Bolshevik government and established the Zhenotdel, the government’s department for women. Under the Bolsheviks, women were granted equal legal status to men, divorce rights, access to birth control, and were the primary benefiters of the nationalization of domestic work (i.e., communal childcare, dining, and laundry halls). Kollontai and the Soviet Union provide us with one of the few examples of Marxist feminism in action. Liberal critics of Kollontai and her Marxist comrades and contemporaries …

Metareasoning, Opportunistic Exploration, And Explanations For Autonomous Indoor Navigation, Raj Korpan

Dissertations, Theses, and Capstone Projects

Autonomous indoor navigation is an important task for mobile robots deployed without a map in real-world environments, such as museums or offices. While it travels, an autonomous robot navigator must contend with lack of prior knowledge, sensor noise, actuator error, and inquisitive people. This dissertation addresses these challenges with a cognitively-based hierarchical reasoning architecture that incorporates learning, exploration, reactivity, planning, heuristics, and explanations. Evaluation by simulation in large, complex, indoor environments shows that a robot controller can successfully navigate without a detailed map of every obstruction's location when it performs limited initial global exploration and plans in its learned spatial …

How Are Refugees Depicted In The Amarillo Globe-News?, Shannon Reimers

Dissertations, Theses, and Capstone Projects

This research uses media analysis to ask how refugees in Amarillo, Texas, are portrayed in the Amarillo Globe-News from 2002 until January 2021. Amarillo, Texas is a small, conservative city with a long history of refugee resettlement. Researching one town, over an extended period, tells a rich story of how refugees are depicted in the local media. This research is important because while the United States takes in refugees on a national level, the local level is where they settle and become long-term members of a community. It shares what a community resettling refugees has to say about them. In …

Delayed Modulation Of Glutamate Receptors By Anti-Epileptic Drugs After Traumatic Brain Injury In Rats, Edgar Rodriguez

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a significant health concern. Around 74 million people sustain a traumatic brain injury worldwide. The damage caused by TBI produces two types of injury; primary and secondary injuries. Primary injury is caused within milliseconds and is irreversible. Secondary brain injury is delayed and produced by molecular, cellular, and structural disruption after the initial injury. One of the most devastating dysfunction after TBI is glutamate neurotransmitter overactivation that could lead to neurotoxic levels of glutamate in the brain (i.e., excitotoxicity). Excitotoxicity has been linked with the development of epilepsy after TBI, also known as post-traumatic epilepsy …

Efficient Protocols For Multi-Party Computation, Tahereh Jafarikhah

Dissertations, Theses, and Capstone Projects

Secure Multi-Party Computation (MPC) allows a group of parties to compute a join function on their inputs without revealing any information beyond the result of the computation. We demonstrate secure function evaluation protocols for branching programs, where the communication complexity is linear in the size of the inputs, and polynomial in the security parameter. Our result is based on the circular security of the Paillier's encryption scheme. Our work followed the breakthrough results by Boyle et al. [9; 11]. They presented a Homomorphic Secret Sharing scheme which allows the non-interactive computation of Branching Programs over shares of the secret inputs. …

Characterizing The Brain Dynamics And Eye Movement Behavior Of Memory-Guided Saccades: A Preliminary Investigation Of Distractor Influence On Memory-Guided Saccades, Angelo V. Colmenero

Dissertations, Theses, and Capstone Projects

Research has helped to shed light on the functional organization and neural mechanisms of distractors on memory-guided saccades. In our current study we have utilized eye tracking and EEG technology to simultaneously record the changes in saccadic eye movement (SEM) behavior and event-related potentials (ERPs) associated with performance on a memory-guided saccade task with distractor conditions. Thirteen healthy control participants (n = 13; 6 female) were tasked to complete 864 memory-guided saccade trials with both visible (white) and invisible (black) distractors presented on a black background before saccade initiation. Compared with the control (black) distractor condition, distractor presentation produced a …

Predictors Of Lexical Accessibility Of Common And Proper Nouns In Older Age: Evidence From The Tip-Of-The-Tongue State, Amy Victoria Vogel-Eyny

Dissertations, Theses, and Capstone Projects

One of the notable language difficulties experienced by healthy older adults is word retrieval failure, specifically the tip-of-the-tongue state (TOT). A TOT occurs when one has a strong sense of knowing the word, such that the semantic content is accessed, but the entirety of the word’s phonology is temporarily inaccessible. Such retrieval difficulty is attributable, at least in part, to characteristics of the target word. Psycholinguistic features may uniquely influence the semantic and/or phonological stages of word production. An additional factor known to influence TOT-likelihood is noun type: proper nouns elicit TOTs more often than do common nouns. The discrepancy …
