The Networking Information Control (NIC) condition was …

Adversarial Training For Skill Learning In A Mobile Robot, Todd W. Flyr

Dissertations, Theses, and Capstone Projects

Machine Learning in mobile robotics is sometimes hampered by the difficulties associated with the creation of a large corpus of labeled data that most neural network based learning algorithms demand. In recent years, advances in the field of machine learning have been facilitated via the creation of large collaboratively-created labeled training datasets that researchers can use as the basis for experiments to validate and improve their candidate neural network architectures. For the field of robotics, however, tasks are so disparate and the physical devices so varied that in most cases the creation of collaborative benchmark datasets are impractical. Obtaining data …

Synthesis, Characterization And Applications Of Europium Based Perovskite Oxide Nanoparticles, Nasim Farahmand

Dissertations, Theses, and Capstone Projects

The synthesis and characterization of nanocrystalline transition and rare-earth metal oxides have been studied widely over the past years. These materials possess unique physical, chemical, magnetic and dielectric properties which make them potential candidates for a wide range of applications such as electronics, energy storage and photocatalysis. There are a number of synthesis methods for preparing these materials, where most of them require stringent conditions such as high pressure and high temperature. However, in this study, a modified sol-gel synthesis has been used with a lower calcination temperature to make uniform nanocrystals of the transition/rare-earth metal oxide family. The focus …

Detection And Morphological Analysis Of Novel Russian Loanwords, Yulia Spektor

Dissertations, Theses, and Capstone Projects

This paper investigates recent English loanwords in Russian and explores ways in which computational methods can help further theoretical research. The goal of the study is two-fold: to find new, previously unattested loanwords borrowed over the last decade and to examine the rate of adaptation of the new borrowings, attested by the degree to which they conform to the constraints of the Russian language. First, we train a finite-state pipeline that combines character n-gram language models, which encode phonotactic and lexical properties of loanwords, with a binary classifier to detect loanwords. The model achieves state-of-the-art performance results during evaluation, surpassing …

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 …

Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova

Dissertations, Theses, and Capstone Projects

Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after …

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, …

From Rulay To Rules: Perceptions Of Prison Life And Reforms In The Dominican Republic’S Traditional And New Prisons, Jennifer Peirce

Dissertations, Theses, and Capstone Projects

This project explores the implementation of reforms to the prison system in the Dominican Republic, with an emphasis on how incarcerated people perceive their conditions and daily life in confinement. In 2003, the Dominican Republic established a New Prison Management Model, focused on international human rights standards and rehabilitation. This model now manages over half of the prison facilities and a third of the incarcerated population, while the previous, “traditional” model continues to operate in tandem. The “new” and reformed facilities (Centers for Correction and Rehabilitation) feature new buildings, programs, and correctional officer staff with multi-disciplinary training. In contrast, the …

The Influence Of Text On Coherence Of Story Retells, Reading Comprehension, Vocabulary Acquisition, And Eye Gaze: A Computer-Based Story Telling Task With Eye Tracking, Nicholas J. Ullrich Iii

Dissertations, Theses, and Capstone Projects

With the growing trend of using multimedia platforms such as YouTube to facilitate storytelling, understanding how and when to integrate text with visuals would benefit both the creators of these platforms and the young readers viewing them. The current study examined the effect of orthography on vocabulary acquisition and narrative comprehension in young readers (children in 2^nd and 3^rd grade, ages 6-9) during a computer-based storytelling task. We aimed to determine if having text available during storytelling benefits readers as predicted by Perfetti’s Lexical Quality Hypothesis (Perfetti & Hart, 2002), or hampers learning as predicted by Mayer’s Redundancy …

Covid, Immigrant Nonprofits, And Online Services: A Case Study Of An Esol Program In Queens, Sabrina Lara

Dissertations, Theses, and Capstone Projects

The coronavirus pandemic has presented challenges to both the public and private spheres of life. For public facing staff in nonprofit organizations, there has been a need to adapt service delivery from in-person to online services. This transition has presented benefits and challenges for participants, especially immigrants who regularly depend on nonprofits for different service needs, as well as nonprofit staff. This case study examines the impact of the COVID-19 pandemic on Jacob A. Riis Neighborhood Settlement, an immigrant-serving nonprofit organization in Queens, New York, and it analyzes how they addressed the transition to fully online service delivery. This organization …

Documenting The Undocumented: Experimenting Europe At The Biometric Migrant Archive, Romm Lewkowicz

Dissertations, Theses, and Capstone Projects

The dissertation is a critical ethnography of the biometric governance of asylum seekers and illegal migrants in the European Union, an integral apparatus for the policing of border-free Europe. Interrogating the paradox of how ‘undocumented migrants’ have been—and are—the most documented subjects in Europe today, the research explores how this documentation assumes the form of biometric technology and its relation to the postwar eradication of Europe’s internal frontiers. At the center of these processes and my research object is Eurodac: a pan-European apparatus for the biometric documentation and regulation of Europe’s paperless migrants and asylum seekers. By attending to both …

Neonatal Opioid Withdrawal Syndrome And Promotion Of Maternal Caregiving: Missing Voices Of Mothers In Medication Assisted Treatment, Hedi Levine

Dissertations, Theses, and Capstone Projects

In response to the increasing rates of opioid exposure among pregnant women and their infants, the Substance Abuse and Mental Health Services Administration (SAMHSA) published “Clinical Guidance for Treating Pregnant Women with Opioid Use Disorder and Their Infants” (2018). The expert panel, which was assembled for this clinical guidance did not include women who were the focal subjects for the guidance. The current qualitative study contributed the missing voices of women in methadone-assisted treatment (MAT) who gave birth subsequent to the publication of the guidance.

The SAMHSA guidance was based upon a preponderance of evidence guiding recommended practices regarding rooming-in, …

The Role Of Estrogen Receptor Alpha In Regulating Messenger Rna 3’ End Processing And Controlling Gene Expression In Breast Cancer Cells, Sophia Varriano

Dissertations, Theses, and Capstone Projects

Estrogen signaling regulates various physiological processes within the female reproductive, cardiovascular, immune, and central nervous systems and is predominantly mediated by estrogen receptors (ER), ERα and ERβ. Transcriptional regulation by ERs has been widely studied, where activated ERs bind either directly to target genes through binding to estrogen response elements or indirectly through interacting with other proteins, resulting in changes in gene expression. However, the potential role of factors involved in the estrogen signaling pathway in posttranscriptional regulation has not been extensively documented. As 70-80% of breast cancers (BCs) are identified as ER(+), studying how these factors, particularly ERα, regulates …

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 …

Characteristics Of Non-Residential (Commuter) Colleges And Factors Affecting Bachelor’S Degree Completion In A Non-Residential College, Sangdong Tak

Dissertations, Theses, and Capstone Projects

Despite the abundant amount of studies about bachelor’s degree completion in higher education, little research paid attention to the characteristics of students attending non-residential institutions, given that this type of college accounts for approximately half of all the higher education institutions in the United States. Using student records and survey data, this study compares the student characteristics between residential and non-residential colleges at the institutional level. In addition, using a primarily non-residential college’s survey and student record data, this research explores diverse factors that affect students’ academic and social integration and their graduation at the individual level. Findings include that …

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 …

The Clothing Left Behind: A Collection Of Stories, Grace Coleman

Dissertations, Theses, and Capstone Projects

Beyond its material use, clothing can have powerful emotional effects such as easing grief from personal loss or serving as a memory recall aid for individuals with dementia. It was during my graduate program that I became interested in exploring the idea that clothing can be powerful beyond its aesthetic. Peter Stallybrass’s essay Worn Worlds: Clothes, Mourning and the Life of Things highlighting clothing’s ability to evoke memories and emotions was influential in setting me on my path to research clothing’s connection to memories. Whether it was embodied identity, grief, dementia, mourning rituals, or collective mourning, I was looking at …

Por Ellas: A Latina’S Autoethnography On Emotions, Achievement And Agentic Learning, Ivonne Barreras

Dissertations, Theses, and Capstone Projects

In the United States, students of Spanish-speaking descent classified as Hispanic, Latino, or Latinx attending public school districts continue to demonstrate alarmingly high academic underachievement and dropout rates. Standards-based learning environments and related assessments tend to marginalize people whose lived realities already make the prospect of achievement daunting. In other words, people living amid high-risk factors, including low educational and occupational aspirations, health, or family-related absenteeism, counterculture or early pregnancy, are often among those whose decision to drop out is most often influenced by social and academic experiences (Rumberger, 2011). Research on neuroplasticity and mindfulness explains the influence emotions have …

Synthesis, Characterization And Applications Of Peptide-Coated Nanoparticles, Mina Sadat Poursharifi

Dissertations, Theses, and Capstone Projects

Ovarian Cancer (OC) is the most lethal female malignancy worldwide, mainly due to its high recurrence rate and poor diagnosis. Most patients present with late stage of the disease, and less than 25% of patients survive the five years mark. Nanotherapy provides significant and unique benefits for drug efficacy, as nanoparticles (NPs) can increase the solubility, bioavailability, and permeability of many potent drugs. Poly(lactic-co-glycolic acid) (PLGA) is one of the most successful biodegradable polymers used in NPs formulations, mainly due to its biocompatibility and biodegradability. Polyethylene glycol (PEG) is one of the most commonly used moieties to prolong the NPs …

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 …

Baccio Del Bianco At The Court Of Spain: Early Modern Scenic Design In Context, Pamela Thielman

Dissertations, Theses, and Capstone Projects

This dissertation examines the life and work of seventeenth-century artist and architect, Baccio del Bianco, to imagine alternative research strategies for histories of theatre. Traditional scholarship of theatre design is rooted in art historical practices, which has limited the consideration of influences beyond visual culture. It has also posited Italian theatre culture as the driver of innovations in Early Modern theatre design. In this project, I argue for and engage in a practice of scenic design historiography that replaces Italy as the dominant actor in the theatrical scene of this period with a more nuanced approach that places emphasis on …

Organizational Decision-Making In The Age Of Big Data And Artificial Intelligence, Anh Luong

All three focus on collaborative decision-making in organizations, with study 1 examining it in the context of big data, while study 2 and 3 in the context of artificial intelligence.

Study 1: This study examines the impact of different manners of presenting information on collaborative decision-making performance. Using controlled economic experiments, I assign participants with a resource allocation decision-making task (adapted from the game theoretic public goods provision problem) and examine the collaborative outcomes of groups when exposed to …

Nuances In Bottom-Up Interpretations: Colombia's And Guatemala's Radically Different Approaches To Transitional Justice, Chelsea L. Carrick

Dissertations, Theses, and Capstone Projects

Scholars have treated “bottom-up” transitional justice processes as a non-nuanced whole, situating grassroots actors in direct opposition to large-scale, or “top-down,” approaches to transitional justice. Such an analysis is limited because it fails to take into account complex contextual factors that contribute to the ways in which bottom-up mechanisms manifest. Colombia and Guatemala are two cases in which bottom-up actors have strived to influence the ways in which peace and justice were articulated by their respective governments; however, the methods and outcomes are strikingly different. In Guatemala, grassroots actors sought to achieve ethnic inclusion, neglecting class and land-based demands. Colombia’s …

Phonetic Contrast In New York Hasidic Yiddish Vowels: Language Contact, Variation, And Change, Chaya R. Nove

Dissertations, Theses, and Capstone Projects

This study analyzes the acoustic correlates of the length contrast in New York Hasidic Yiddish (HY) peripheral vowels /i/, /u/, and /a/, and compares them across four generations of native speakers for evidence of change over time. HY vowel tokens are also compared to English vowels produced by the New York-born speakers to investigate the influence of language contact on observed changes. Additionally, the degree to which individual speakers orient towards or away from the Hasidic community is quantified via an ethnographically informed survey to examine its correlation with /u/-fronting, a sound change that is widespread in the non-Hasidic English-speaking …

Conformation Of The Protein-Free Spliceosomal U2-U6 Snrna Complex And Remodeling By Mg2+ And Proteins, Huong Chu

Dissertations, Theses, and Capstone Projects

Splicing of precursor messenger RNA is an essential process in eukaryotes in which the non-coding regions (introns) are removed and coding regions (exons) ligated together to form a mature mRNA. This process is catalyzed by a multi-mega Dalton ribonucleoprotein complex called the spliceosome, which is assembled from five small nuclear ribonucleoproteins (snRNP) in the form of RNA-protein complexes (U1, U2, U4, U5 and U6) and hundreds of proteins. U2 and U6 small nuclear (sn)RNAs are the only snRNAs directly implicated in catalyzing the splicing of pre-mRNA, but assembly and rearrangement steps prior to catalysis require numerous proteins. Previous studies have …

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 …
