Longitudinal Changes Of Regional Myelin Water Fraction During First Year After Moderate-To-Severe Diffuse Traumatic Brain Injury, Likowsky L. Desir

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a worldwide health issue with a highly heterogeneous disease characterization, including widespread white matter damage in the brain. Most non-invasive white matter imaging methods currently available, including diffusion tensor imaging (DTI), cannot reliably measure the degree of neurodegeneration due to various confounds, making it challenging to select an endpoint measure for neuroprotective clinical trials. The present study investigates longitudinal white matter changes, measured by a novel imaging metric, apparent myelin water fraction (aMWF), and its relationship with neuropsychological measures during the first year after TBI. Data from 15 adult patients with moderate-to-severe TBI and 30 …

The Influence Of Evidence-Based Sex Discrimination Policies On Women’S Perceptions Of Organizational Climate, Sexism, And Identity Safety, Maya A. Godbole

Dissertations, Theses, and Capstone Projects

Sexism has proven to be a stubborn barrier to women’s participation and advancement in workplaces and academic institutions (Rosette, Akinola, & Ma, 2017). Importantly, sexism in organizational settings has endured despite the implementation of federal, state, and organizational policies that prohibit discriminatory behavior. One reason for this may be that because organizational policies are typically written for the purpose of complying to federal and state laws, they do little to foster psychological safety among employees and address the “chilly” organizational climates that enable sexism. To that end, the current research aimed to (a) develop novel, evidence-based sex discrimination policies and …

Bodies On The Line: The Politics Of Regulating Pornography In Los Angeles, Christopher J. Baum

Dissertations, Theses, and Capstone Projects

This dissertation examines the regulation of sexually explicit media in the United States – specifically in Los Angeles – and the site used to understand it is the modern pornography industry at its points of production. I argue that since the industry's formation in the early- 1970s, regulatory efforts have focused on controlling porn worker’s bodies as a way of enacting broader social transformations and reshaping the domains of erotic life. Drawing from eighteen months of ethnographic research, I explore several interlocking forms of regulation. I begin by examining the formation of pornographic production cultures during what I call the …

Efficiency Of The Acoustic Change Complex For Various Stimulus Presentation Strategies In Infants, Lisa Goldin

Dissertations, Theses, and Capstone Projects

The acoustic-change-complex (ACC) is an objective measure that can be used to study whether sounds are encoded at the level of the cortex. The goals of this study were: 1) To determine if the ACC can be elicited in infants, and 2) To establish whether eliminating the silent interval between stimuli and using a continuously alternating stimulus is more efficient in infants than the traditional interrupted stimulus presentation method. If the continuously alternating stimulus is more efficient, then 3) To determine why the continuously alternating stimulus is more efficient.

Twenty-one infants aged 2 months to 13 months old served as …

How Frustration Impacts The Relationship Between Potential For Child Physical Abuse Perpetration And Emotion Processing, Amanda L. Zwilling

Dissertations, Theses, and Capstone Projects

Research conducted over the past 20 years has substantiated the serious, long-lasting impacts of child physical abuse (CPA) has on individuals, families, and society. Research has also suggested several appreciable risk factors for perpetration of CPA. Intergenerational transmission of abuse, described as the personal experience of abuse or neglect during childhood, is prominent in the literature as a predictor of subsequent perpetration of CPA. However, the majority of individuals who experience abuse in childhood do not subsequently engage in perpetration of child abuse as adults. As such, the literature has sought to investigate risk factors that mediate the relationship between …

Desire, Culture, And The Body, Zoey Lavallee

Dissertations, Theses, and Capstone Projects

What is the nature of desire? In this dissertation I develop a theory of desire according to which desires are essentially enculturated states that play the role of presenting favorable outcomes that act as inputs to intention formation, and thereby intentional action. This analysis of desire debunks a common assumption shared by prominent accounts of desire in philosophy of mind, what can be called the dualist assumption: that bodily desires such as urges and appetites differ in kind from conceptual desires that are typically described as higher cognitive attitudes. I argue that the desires traditionally understood as bodily or appetitive …

From An Art To A Science: Features And Methodology In Computational Authorship Identification, Jonathan I. Manczur

Dissertations, Theses, and Capstone Projects

Nearly thirty years ago, the United States Supreme Court revaluated the criteria for accepting forensic science and expert testimony, challenging Forensic Linguistics to assert itself as a reputable science. Much work has been produced in the interim to that end, but much still needs to be accomplished to satisfy the judicial standards. Computational linguistics has the potential to provide that necessary analytical framework. This paper’s intent is two-fold. First, there are two competing theories on the proper features necessary to identify an unknown author. Four features were drawn from the syntactic computational linguistics tradition and four from computational stylometry to …

The Lopez Effect Remixed: The Significance Of Mattering Through A Hip-Hop Lens In Education And Beyond, Kashema Hutchinson

Dissertations, Theses, and Capstone Projects

The goal of this dissertation is to examine the theoretical frameworks of mattering (Rosenberg & McCullough, 1981; Schlossberg, 1989; Love, 2018) in traditional and non-traditional spaces through a Hip-hop lens. When mattering is applied to marginalized groups, it centers them to a certain extent. In my dissertation, I examine how Dr. Nadia Lopez, the former principal of junior high school, Mott Hall Bridges Academy (MHBA), employed mattering in her holistic approach to education. Her dedication to her students, faculty and staff went viral on the popular blog Humans of New York in January 2015. Lopez’s commitment is to “open a …

The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas

Dissertations, Theses, and Capstone Projects

Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …

Dual Control Of One Component Signaling: Mechanistic And Structural Insights Into El222 Active States, Uthama Phani R. Edupuganti

Dissertations, Theses, and Capstone Projects

Photoreceptors play a crucial role in signal transduction as specialized proteins which sense light as environmental stimuli and transduce the signal to control of downstream functions. Here we focus our attention on one class of these proteins, the Light-Oxygen-Voltage (LOV) domain, which is sensitive to blue light via an internally-bound flavin chromophore. Since their initial discovery in plant phototropins, many details of their photochemistry, chromophore interactions, and use with a diverse set of functional effectors have been described. However, several key details, especially a comprehensive understanding of signaling mechanism and its regulation, still remain elusive due in part to the …

Deserving To Belong: Complex Narratives Of Working And Learning In Self-Contained Spaces, Emily B. Clark

Dissertations, Theses, and Capstone Projects

Using the tools of narrative, discourse, and visual analysis, this study examines the sensemaking of educators and former students who work(ed) and learn(ed) in self-contained special education settings. In three individual interview sessions (and one final sensemaking session), I interviewed fourteen educators and nine former students who work(ed) and learn(ed)in different kinds of self-contained settings within the New York City public school system.This project is not about a specific school, as self-contained classrooms exist in different configurations and locations throughout the city and the country. To protect the participants, all names and references to specific schools and programs have been …

Development Of High-Throughput Methods For Screening Venom Peptides, Tanya Napolitano

Dissertations, Theses, and Capstone Projects

Bioactive venom peptides are increasingly being explored as drug leads in pharmaceutical research because of their immense therapeutic potential, however there is a need to more efficiently screen and characterize these peptides to discover medicinal leads more quickly.1,2 The Holford lab has leveraged recent technological achievements in genomics, transcriptomics, and proteomics to produce a leap in the discovery of venom peptides from previously hard to characterize small and neglected venomous animals such as Terebridae, an understudied lineage of the Conoidea Superfamily.4, 5–7 With the rise of -omic technologies the floodgates have opened and venom researchers are awash with large datasets …

The Federalist Papers' Account Of Human Nature, Jeffrey P. Smith

Dissertations, Theses, and Capstone Projects

This paper is an analysis of the account of human nature found in The Federalist Papers. This interpretation assumes The Federalist is a work of political rhetoric and advocacy, but also one of genuine significance as political science and philosophy. As a book, The Federalist is a coherent whole, which offers a coherent account of human nature, despite the collective nature of its authorship, the time pressures of its publication, and the piecemeal nature of its workmanship. This understanding of human nature is the thread which runs through all its analysis and numbers. Its arguments asserting the inadequacies of …

Put Yourself First (In A Sexy Way): Postfeminist Beauty Messaging And Resistant Media Texts, Margarita Artoglou

Dissertations, Theses, and Capstone Projects

The makeover montage trope is one of the most recognizable in media content aimed at young women, sending the message that social status and acceptance are only a new outfit and face of makeup away. While this trope and its message have been heavily critiqued by scholars, the message that beauty—and all its social benefits—can be achieved through consumerism has not disappeared, though the means by which this message is conveyed has changed. As a result of companies co-opting feminist rhetoric, conforming to standards of beauty has been recast as a “choice” one makes for herself, often wrapped in the …

Learning Deep Visual Features From Limited Labeled Data, Longlong Jing

Dissertations, Theses, and Capstone Projects

Large-scale labeled datasets are generally required to train deep neural networks in order to obtain better performance in visual feature learning for computer vision applications. To reduce the extensive cost of collecting and annotating large-scale labeled datasets, various machine learning methods are proposed to learn general visual features including semi-supervised methods which learn visual features from a small size of labeled data and a large amount of unlabeled data, weakly supervised methods which learn visual features from coarse-grained labeled data, and self-supervised methods which learn visual features from large-scale unlabeled data. In this thesis, we investigate a number of approaches …

Youth Bystander Intentions To Intervene In Peer Intimate Partner Violence: The Co-Influence Of Perceived Perpetrator Race And Perceived Culpability, Nana Amoh

Dissertations, Theses, and Capstone Projects

In recent years, bystander intervention programs that focus on addressing violence have notably become more popular and prevalent on college campuses. Bystander intervention programs serve to help college students identify and intervene in emergency situations like intimate partner violence. Despite advances in the bystander intervention literature, there is a dearth of research that has examined bystander intentions to intervene in situations of intimate partner violence among youth who have witnessed violence between peers. This study examined bystander intentions to intervene among young adults who witnessed peer male-to-female physical intimate partner violence and whether intentions to intervene varied depending on perpetrator …

Unthinkable Conditions: Affect And Environment In Romanticism And Speculative Fiction, Amelia Z. Greene

Dissertations, Theses, and Capstone Projects

Unthinkable Conditions bridges two literary periods and two theoretical modes in order to illustrate important parallels between historical periods and the writers who attempted to approach the changing environmental conditions of their respective eras. Each chapter names and theorizes a unique form of feeling which then serves as a framework for eco-affective analysis, drawing from existing studies in the environmental humanities and in studies of affect in order to construct a hybrid theoretical model which more fully accounts for the work of the writer treated in each chapter. The central claim of this dissertation is that vital affective innovations accompany …

Treatment, Diagnostic, Demographic, And Historical Factors Affecting Mental Health Diversion Outcomes, Amanda L. Reed

Dissertations, Theses, and Capstone Projects

The deinstitutionalization movement, which began in the 1950s and culminated in the closure of most psychological institutions by the 1980s, promised to usher in a new era of community mental health (Torrey et al., 2010). While the movement, which began largely due to advances in psychological treatment and the exposure of widespread abuses in asylums, was well-intentioned, it ultimately created new problems for people experiencing mental illness. Many of the programs designed to handle the influx of newly-released patients were never fully funded or well-received (Human Rights Watch, 2003). The criminal justice landscape also changed dramatically around the same time, …

Towards A Decolonial Feminist Aesthetics: Gender, Race, And Empire In Theresa Hak Kyung Cha’S Dictee, Juwon Jun

Dissertations, Theses, and Capstone Projects

Defining revolutionary struggle as a struggle between fictions, Trinh T. Minh-ha asserts that art in revolution is a spiritual presence which widens the conception of freedom. Political struggle is constituted by clashes in differently written and conceived realities—hinged on the creation and realization of multiple liberatory fictions. Liberation then requires us to attend to creating new myths and conceptions of freedom which can free us from the current structures of domination that produce current subjects and realities. If culture is indeed an “essential element in the history of a people,” mapping decoloniality in cultural and aesthetic fields may be essential …

What We Owe To Our Audience: The Hermeneutical Responsibility Of Fiction Creators, Kathryn Wojtkiewicz

Dissertations, Theses, and Capstone Projects

The goal of this project is to provide a theoretical underpinning for the belief that creators of fiction should dedicate time to diversifying the cast of characters in their fictions, and to avoiding harmful stereotypes when doing so. I establish this as a hermeneutical responsibility: because of the epistemic influence fictions can wield over their audiences, trafficking in harmful stereotypes of marginalized identities (instances of which I call Bad Representation Problems) or excluding marginalized identities entirely (which I call No Representation Problems) from one’s fictions can reinforce harmful beliefs about real people with those identities. The more popular the fiction, …

Acoustic Changes Following Clear Speech Intervention, Polina Shuminsky

Dissertations, Theses, and Capstone Projects

Studies have shown that the speech perception of individuals with hearing loss and other perceptual difficulties improves when talkers deliberately use clear speech. Several investigations have reported increased recognition scores of 11 to 34 percentage points for various listener groups in response to naturally produced clear speech. Studies show that clear speech production is highly variable across talkers. Therefore, a consistent method of eliciting clear speech that leads to more unified and consistent production outcomes is needed. Limited evidence suggests that a training program on how to speak clearly may yield greater listener benefit than clear speech produced naturally. The …

Which Way South? A Chronicle Of The Autoworkers’ Ill-Fated Quest For A Land Route From Detroit To Chattanooga (With A Brief Sojourn In Germany), Abraham Walker

Dissertations, Theses, and Capstone Projects

Declining unionization rates in the private sector have long been a major object of research across the social sciences and among students of the labor movement. Nowhere is this issue felt more acutely than in core productive sectors of the American South, where employers have beaten back nearly every significant organizing effort, even as the region continues to attract mass industry. These problems are epitomized by the United Autoworkers Workers’ 2014 defeat at the hands of German automaker Volkswagen in Chattanooga, Tennessee, where it failed to win an election despite management’s ostensible neutrality. Though various competing explanations have been offered, …

Some Notes On Birds: Language And Attention In The Age Of Social Media, Aimee Lamoureux

Dissertations, Theses, and Capstone Projects

Technology, social media, and its affiliated distractions are now an ever-present part of our daily lives. Attention is a commodity, one which tech companies value because it delivers them bigger and bigger profits. Their products are intentionally designed to be additive, to demand more and more of our time and attention throughout our day. However, attention is not simply a commodity, but the way in which we connect with the external world and attend to our everyday experience. The world that we create in the mind is the world that ends up forming the reality of our everyday lives. Complex …

An Assessment Of Undergraduate Students’ Research Literacy, Milushka M. Elbulok-Charcape

Dissertations, Theses, and Capstone Projects

Research literacy refers to the knowledge and application of statistics and research methods knowledge. Research literacy is important because it enables individuals to become autonomous lifelong learners and informed research consumers. Compared to other types of literacies (e.g., informational, statistical, scientific, etc.), research literacy in the social sciences has received limited attention in psychological theory and research. As a result, assessments of research literacy have notable limitations. Some assessments place undue emphasis on content knowledge of statistics and research methods neglecting the application of knowledge, others present items in a de-contextualized manner, exploring conceptions or attitudes toward research itself rather …

Linear And Non Linear Properties Of Two-Dimensional Exciton-Polaritons, Mandeep Khatoniar

Dissertations, Theses, and Capstone Projects

Technology has been accelerating at breakneck speed since the first quantum revolution, an era that ushered transistors and lasers in the late 1940s and early 1960s. Both of these technologies relied on a matured understanding of quantum theories and since their inception has propelled innovation and development in various sectors like communications, metrology, and sensing. Optical technologies were thought to be the game changers in terms of logic and computing operations, with the elevator pitch being "computing at speed of light", a fundamental speed limit imposed by this universe’s legal system (a.k.a physics). However, it was soon realized that that …

Food-As-Medicine: An Everyday Strategy Of Health, Rachel Rebecca Bogan

Dissertations, Theses, and Capstone Projects

Using food-as-medicine, a valuable strategy of health, as its focus, this dissertation examines why and how New Yorkers use food to negotiate their health. I argue that while using food medicinally is a common health practice, food-as-medicine operates unequally among different groups of New Yorkers. I attribute this inequity, in part, to how those in power, including public health experts, biomedical doctors, and the food industry, operationalize food-as-medicine as a health remedy and to a neoliberal, healthist context that ties people’s morally “correct” uses of food-as-medicine to their abilities to access “good” citizenship and optimal health.

I chose to write …

Countersexuality In Times Of Neomachismo: Representations Of Gender In Contemporary Spanish Performance (1988–2019), Mara I. Valderrama

Dissertations, Theses, and Capstone Projects

This dissertation traces innovative representations of gender in Spanish contemporary experimental theatre and performance art. Using Paul B. Preciado’s concept of countersexuality, I argue that an embodied practice like theatre can model new forms of being-in-the-world that supersede binaries of gender and sexuality. Specifically, I analyze how emblematic performances marshal countersexual acts to intervene in the context of Spain and neomachismo, an antifeminist trend that, in the last two decades, has sought to reassert masculine structural power. I attempt to write marginalized cases into the academic narrative that might otherwise have been overlooked or erased for being experimental in their …

Automated Code Engine For Tensor Hypercontraction: Derivation, Optimization And Implementation Of Rank-Reduced Coupled Cluster Theories, Yao Zhao

Dissertations, Theses, and Capstone Projects

The ultimate goal of electronic structure theory is solving the electronic Schr¨odinger Equation. However, even accurate approximations of solving Schr¨odinger Equation, such as high order coupled cluster theories, require computational efforts that are too demanding to be applied on large chemical systems. This thesis tackles the problem of curse of dimensionality: how to reduce the time complexity of high-accuracy coupled cluster methods in order to accelerate computations of molecular energy. On one hand, we believe that low-rank approximation (i.e. Tensor HyperContraction) of high-order tensors appearing in coupled cluster theory is a promising way to achieve rank-reduced coupled cluster theory. On …

Analysis Of Transplantable Photoreceptor Replacement Cell Chemotactic Mechanisms In Retinal Biomimetic Ligand Gradients, Onyekwere Onwumere

Dissertations, Theses, and Capstone Projects

Disease or trauma induced loss of rod and cone photoreceptors is a major cause of vision loss worldwide. To replace lost photoreceptors and restore vision, laboratories around the world are investigating photoreceptor replacement strategies using subretinal injection of photoreceptor precursor cells (PPCs) and retinal progenitor cells (RPCs). A major obstacle in the field is that transplanted photoreceptor replacement cells exhibit extremely limited migration into host retina following injection into the subretinal space. In this work, we show that PPCs and host retinal interaction bioinformatics modeling can identify key pathways involved in photoreceptor replacement cell migration and invasion behaviors. In addition, …

Topological Classical Wave Systems With Modulations, Interactions, And Higher-Order Topological States, Mengyao Li

Dissertations, Theses, and Capstone Projects

Topological phases in classical wave systems, such as photonic and acoustic, have been actively investigated and applied for wave guiding, lasing, and numerous other novel phenomena and device applications Topological phase transitions enable robust boundary states, and the field has been broadening recently into a vast variety of systems with temporal modulations and interactions. Floquet modulation, for example, is the modulation applied periodically in time which may break symmetries and leads to novel topological phases.

Introducing non-Hermitian Floquet modulation enables more interesting phenomena including bandgap in imaginary part of the spectrum and gainy/lossy topological edge states with complex energy values. …
