Bitrdf: Extending Rdf For Bitemporal Data, Di Wu

Dissertations, Theses, and Capstone Projects

The Internet is not only a platform for communication, transactions, and cloud storage, but it is also a large knowledge store where people as well as machines can create, manipulate, infer, and make use of data and knowledge. The Semantic Web was developed for this purpose. It aims to help machines understand the meaning of data and knowledge so that machines can use the data and knowledge in decision making. The Resource Description Framework (RDF) forms the foundation of the Semantic Web which is organized as the Semantic Web Layer Cake. RDF is limited and can only express a binary …

Learning Beyond Measure: Critical Numeracy And Resistance To Racial Capitalism, Atasi Das

Dissertations, Theses, and Capstone Projects

In this three-article dissertation, I connect with and expand from learning theories and mathematics and numeracy practices to reimagine numeracy as a potential tool towards liberation and human emancipation. Developing a framework and activity of critical numeracy, I explore the ways numbers and static categories have been used to “objectively” create, reproduce, and reify hierarchies within historical contexts and power relations. The core of this work examines, what do numbers and numeracy mean for us? Who are “the us” we can organize for? And for what purpose can and should we utilize, teach, and learn with numbers in and beyond …

Driven Dipolaritons In Van Der Waals Transition Metal Dichalcogenide Heterostructures: Properties And Applications, Patrick Serafin

Dissertations, Theses, and Capstone Projects

The need for advances in optical computation leads us toward the investigation of novel methods of re-routing light in optical circuits. The behavior and properties of electrically driven exciton-dipolaritons in van der Waals transition metal dichalcogenides are investigated as a platform for realizing working elements of a polaritronic transistor. In this work, we consider exciton-dipolaritons, which are three-way superposition of cavity photons, direct excitons, and indirect excitons in a bilayer semiconducting system embedded in an optical microcavity. We start by providing motivation for our study of polaritons and then survey the fundamental properties of exciton-dipolaritons. We also survey the basic …

Fathers Are Fathers Are Fathers: How Sociocultural Context And Sexual Orientation Influence The Gendering Of Children, Sarah M. Frantz

Dissertations, Theses, and Capstone Projects

Though the body of literature on gay father-headed families indicates there is no significant differences on measures of gender normativity and well-being between children raised with two dads and their peers raised by heterosexual parents, there is a proliferation of anti-LGBTQ+ policies throughout the United States aimed at limiting this community’s rights and silencing their lived experiences. Given that sociocultural and political environments vary greatly state-to-state, it is important to see how the specific context in which fathers live may impact their differential parenting of sons and daughters, their gender beliefs, and the way they feel they would navigate gender …

Mandatory Disclosures And Investment Efficiency: Evidence From The Conflict Minerals Disclosure Requirement, Ge Dong

Dissertations, Theses, and Capstone Projects

I examine the effects of mandatory disclosures on firms’ investment efficiency using the conflict minerals disclosure requirement of the Dodd–Frank Act of 2010. I find that firms’ investment efficiency improves following the adoption of the regulation. I then examine whether this improvement in investment efficiency is due to the regulation forcing managers to acquire new information and I document two important findings. First, I find that firms with a better internal information environment are more likely to experience improved investment efficiency. Second, I find that firms manage raw materials more efficiently and make changes to their supply chains after disclosing …

Sensitized Photooxidation Of Prenylated Compounds: Mechanisms Of Downstream Dark Effects And Phototoxicity Priming, Shakeela Jabeen

Dissertations, Theses, and Capstone Projects

This thesis consists of four chapters as detailed below.

Chapter 1 discusses a singlet oxygen priming mechanism. Airborne singlet oxygen derived from photosensitization of triplet dioxygen is shown to react with an alkene surfactant (8-methylnon-7-ene-1 sulfonate) leading to ‘ene’ hydroperoxides that in the dark inactivate planktonic E. coli. The ‘ene’ hydroperoxide photoproducts are not toxic on their own, but they become toxic after the bacteria are pretreated with singlet oxygen. The total quenching rate constant (k_T) of singlet oxygen of the alkene surfactant was measured to be 1.1 × 10⁶ M⁻¹ s^{− …}

Intelligence Testing In The New (Langu)Age: Effects Of Item-Type And Assessment Medium Features On Fluid Intelligence Test Linguistic Group Score Differences, Paige R. Alenick

Dissertations, Theses, and Capstone Projects

As fluid intelligence tests are an integral part of modern employee selection protocols, assessment designers are tasked to ensure the construct is measured accurately for all test-takers regardless of their demographic traits. Disparities in bilingual and monolingual working memory capabilities, which are critical for successful fluid intelligence test performance, might make it challenging for test designers to accomplish this goal. Best design practice in such cases is to identify assessment conditions that allow for equitable expression of the test construct. Thus, the purpose of this study was to examine whether the content of items present on a fluid intelligence test …

Influence Level Prediction On Social Media Through Multi-Task And Sociolinguistic User Characteristics Modeling, Denys Katerenchuk

Dissertations, Theses, and Capstone Projects

Prediction of a user’s influence level on social networks has attracted a lot of attention as human interactions move online. Influential users have the ability to influence others’ behavior to achieve their own agenda. As a result, predicting users’ level of influence online can help to understand social networks, forecast trends, prevent misinformation, etc. The research on user influence in social networks has attracted much attention across multiple disciplines, from social sciences to mathematics, yet it is still not well understood. One of the difficulties is that the definition of influence is specific to a particular problem or a domain, …

Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía

Dissertations, Theses, and Capstone Projects

Urban growth and expansion are a major component of global environmental change, with impacts on climate, air and water quality, biodiversity, and human well-being. Forests embedded in urban landscapes are critical in mitigating these impacts at local, regional, and continental scales. However, assessing urban forests is difficult because cities are heterogenous in physical, chemical, biological, and social dimensions. This heterogeneity has constrained how urban forests are defined, and therefore, how they are studied. The objective of this dissertation is to determine how these biophysical and social factors drive ecological processes in urban forests and will address three outstanding challenges in …

The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig

Dissertations, Theses, and Capstone Projects

Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …

Recovering Authenticity: Care, Conversation And Value, Shannon M. Brick

Dissertations, Theses, and Capstone Projects

Suppose you learn that your steak-loving friend has just adopted a vegan diet. You ask her what prompted the change, and she tells you that someone she trusts recently tweeted “Eating meat is immoral.” Your friend’s response is a little disappointing and shallow, but why? Most of our knowledge comes from trusting what other people tell us, so why, when it comes to moral matters, does deference seem inappropriate? Some philosophers think it’s because moral testimony cannot transmit important epistemic goods, like knowledge or understanding. Others think that when people defer to moral testimony, their actions or characters will be …

The Impossible Situation? Impasse As Psychotherapeutic Paralysis, Possibility, And Progress, Leo Cancelmo

Dissertations, Theses, and Capstone Projects

Psychotherapeutic impasse has long been understood in the clinical literature as treatment stagnation and even failure, both from one-person and two-person psychodynamic perspectives. However, there is a dearth of empirical research that delves deeper to understand this complex and rich phenomenon. Using semi-structured interviews with nine psychodynamic therapists speaking about individual adult patients, this study examined experiences of impasse to better understand treatments that become embroiled in a kind of paralysis. Qualitative analyses revealed dyads where patients were conceptualized as struggling chronically with negative feelings about themselves and others, and who experienced traumatic personal histories. Impasse in and of itself …

Predicting Stress In Russian Using Modern Machine-Learning Tools, John Schriner

Dissertations, Theses, and Capstone Projects

In the Russian language, stress on a word is determined via often complex patterns and rules. In this paper, after examining nearly a century of research in stress rules and methods in Russian, we turn to see if modern machine learning tools can aid in predicting stress. Using A.A. Zaliznyak’s dictionary grammar and over 300,000 word forms, we derived stress codes to aid in predicting which syllable primary stress falls on. We trained an LSTM neural network on the data and conducted eight experiments with added features such as lemma, part of speech, and morphology. While the model performed better …

Marx, Race, Black Radicalism, And Racial Justice, Gregory Slack

Dissertations, Theses, and Capstone Projects

In this dissertation I defend the claim that not only was Marx not an anti-black racist, he was an anti-anti-black racist, despite sometimes employing racist language and epithets. I prove this claim by adducing massive amounts of textual evidence from Marx and Engels’ writings, spanning their entire careers as writers and revolutionaries, where time and again they condemn black slavery and the slave-trade, look forward to and call for their abolition, and aim at a future of racial justice and equality for black people, as a component part of communist justice for all working people, under a communist mode …

Expulsive Greening: A Cross-Sectional Analysis Of Green Gentrification In The Resilience Paradigm, Brooklyn 2010–2020, Rose Jimenez

Dissertations, Theses, and Capstone Projects

Background: This project analyzes the spatial coincidence between gentrification typologies and urban greening in Brooklyn, New York from 2010 to 2020. Assets formed under the NYC Green Infrastructure Program were chosen as a proxy for urban greening to represent the spatial practice specifically within the 21st-century climate change resilience paradigm of development. Methods: First, five indexes measuring variations of economic and demographic conditions related to gentrification were applied to Brooklyn for comparative analysis: NOAA’s Social Vulnerability Indicators of Gentrification Pressure, The NYC Heat Vulnerability Index, The Small Area Index of Gentrification, Typologies of Gentrification and Displacement, and The Housing Risk …

Carceral Calisthenics: Physical Culture In The Hood, Albert L. De La Tierra

Dissertations, Theses, and Capstone Projects

How do racialized men who reside in structurally marginalized locales that are putatively regarded as “the hood” navigate and manage their social conditions? This dissertation sheds light on this question by treating “street workout,” a physical culture centered around calisthenics exercises performed in public space, as an empirical site for generating a situated understanding of how some Black men assert themselves in social space at the same time that they are asserted upon by social forces. Taking an ethico-onto-epistem-ological stance that refuses the colonial gaze (a ubiquitously employed optic that dehumanizes racialized people), this dissertation asks: (1) What embodied practices …

Transforming Afterschool Programs Into "Engines Of Development": A Policy Analysis Of The Federal 21st Century Community Learning Centers, Jane Quinn

Dissertations, Theses, and Capstone Projects

Although schools receive most of the attention in discussions of and research about educational policy, an equally important—and under-investigated—arena is the non-school hours. American students spend more time outside of school than in school, and a host of studies have shown that the ways young people spend their discretionary time can greatly influence their short-term and long-term outcomes. Issues of educational equity are deeply embedded in the topic because opportunities to participate in high quality out-of-school learning experiences are not evenly distributed in American society. The single most important policy target in this aspect of student life is the federal …

Determining The Roles Of The Oligomerization And C-Terminal Domains In Mutant P53 Gain-Of-Function Activities, George K. Annor

Dissertations, Theses, and Capstone Projects

The tumor suppressor p53 (TP53) gene is often mutated in cancer, with missense mutations found in the central DNA binding domain, and less often in the oligomerization domain (OD) and C-terminal domain (CTD). The OD and CTD have been found to be critical for the tumor suppressor functionality of wild-type p53 (wtp53). Specific missense mutations in the DNA binding domain have been found to confer new gain-of-function (GOF) activities. Mutations that destabilize tetramer formation, or deletion of key lysine residues within the CTD, downregulate the ability of wtp53 to transactivate (increase the rate of transcription of) its target …

Ssri-Induced Emotional Blunting: A Study Of Cognitive Changes In Pharmaceutically Treated Depression, Carly Tocco

Dissertations, Theses, and Capstone Projects

Objective: In recent years, approximately 12.7% of the American population are on a prescribed antidepressant medication. Selective Serotonin Reuptake Inhibitors (SSRIs) are a widely used pharmacological treatment for depressive and anxiety disorders, primarily due to their tolerance levels, mild side effects in comparison to other antidepressants, and broad range of clinical indications. However, there are still numerous concerns about SSRIs’ ability to improve depressive symptoms without adding side effects such as sexual dysfunction, gastrointestinal upset, and a restricted range of emotions. Although patients typically claim that they have less emotional pain while on SSRIs than they do during a depressive …

Essays On Machine Learning Methods In Economics, Mani Bayani

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters on machine learning modeling in economics. Chapter 1 - Robust PCA Synthetic Control: In this chapter, I propose an algorithm for comparative studies called robust PCA synthetic control. My algorithm builds on the synthetic control model of Abadie et al., 2015 and the robust synthetic control model of Amjad et al., 2018. I apply all three methods (robust PCA synthetic control, synthetic control, and robust synthetic control) to answer the hypothetical question, what would have been the per capita GDP of West Germany if it had not reunified with East Germany in 1990? I …

Problematic Social Media Use, Social Comparison, And Defeat: An Intensive Longitudinal Investigation, Natalia Macrynikola

Dissertations, Theses, and Capstone Projects

Self-injurious thoughts and behaviors (SITBs) have steadily risen over the past two decades. The simultaneous dramatic increase in social media use has fueled concerns that using social media may be contributing to suicide risk. Although an emerging body of evidence reveals associations between certain patterns of social media use and SITBs, most research studies have not been designed to assess the temporal order of these variables and have neglected to investigate mechanisms underlying such associations. As a result, whether and how social media use may be conferring suicide risk remains unclear. To address this gap, the present study examined a …

White Blinders: A Study Of Race Relations Theory In Britain, 1948–1988, Matthew T. Sherman

Dissertations, Theses, and Capstone Projects

This dissertation studies the early generation of scholars who developed the academic field of race relations in Britain from the 1940s into the 1980s. The research and methodology performed throughout this period was both innovative and problematic due to the approaches taken. Early scholars, such as Kenneth L. Little, Michael Banton, Sheila Patterson, and John Rex, provided the dominant schools of thought in the study of race relations in Britain up to the early 1970s. This dissertation studies the origins and development of an interdisciplinary field of study within the context of a nation and society coming to grips with …

The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies

Dissertations, Theses, and Capstone Projects

Cannabis use among patients with schizophrenia-spectrum disorders (SSD) is at significantly greater levels than in healthy populations but the impact of cannabis on neural mechanisms of clinical improvement is poorly understood. Cognitive functioning and neural connectivity are disrupted as a result of both SSD and cannabis use, and research indicates that neuropsychological capacity and connectivity of the striatum, a region involved in salience and reward processing, may be integral to effective antipsychotic drug (AP) treatment response. Despite this overlap, no previous research has investigated the effect of cannabis on the brain functions implicated in AP treatment response. The present study …

The Politics Of Media Freedom, Kyong Mazzaro

Dissertations, Theses, and Capstone Projects

Democratization theories assume that democracy and media freedom go hand in hand. However, in democracies, politicians and individuals who have a stake in political battles often attack journalists. How can political and electoral incentives that are at the heart of democracy create a minefield for journalists? Examining cross-national patterns of censorship and the experiences of journalists in Venezuela, Mexico, and Brazil captured in over 4,600 case narratives, 30 field interviews, and historical documents, I study the circumstances under which political rivalries result in anti-media violence. I show that state and non-state actors are more likely to target journalists as a …

Astrophysics, Cosmology And Particle Phenomenology At The Energy Frontier, Jorge Fernandez Soriano

Dissertations, Theses, and Capstone Projects

This dissertation consists of two parts, treating significantly separated fields. Each part consists on several chapters, each treating a somewhat isolated topic from the rest. In each chapter, I present some of the work developed during my passage through the graduate program, which has mostly been published elsewhere.

Part I – Cosmic Rays and Particle Physics

• Chapter 1: In this chapter we present an introduction to the topic of cosmic ray physics, with an special focus on the so-called ultra high energy cosmic rays: their potential origins, effects during their propagation between their sources and Earth, the different techniques used …

The Role Of Mortality Salience And Social Identity In Police Officers And Students Reporting Misconduct, Anna M. Stenkamp

Dissertations, Theses, and Capstone Projects

Over the past several decades, high-profile police shootings, police brutality, and police misconduct have contributed to a decreased trust in policing in the United States. Beyond the severity and abuse of power, many of these incidents have also revealed that officers have covered up these incidents from the public. The refusal of police officers to both report misconduct or cover it up is well established and known as the “blue wall of silence.” However, no previous studies have examined the psychological processes behind this failure to report fellow officer misconduct. Two psychological theories that may explain this failure are Terror …

Essays On Spillover Effects Across U.S And China, Zhuo Xi

Dissertations, Theses, and Capstone Projects

Chapter1: With the rapid development and continuous advancement of economic globalization, the links between countries around the world have become increasingly tight. Among them, the United States, as the world's largest economy, its monetary policy is bound to cause significant spillover effects on other economies around the world. By constructing a Threshold SVAR model with monthly data from 1996 to 2019, this paper empirically investigates the spillover effects of US monetary policy on China's economy during different U.S policy regimes. The transmission mechanism of such effects has been tested through different channels including policy channel, trade channel, asset value channel …

Essays In Asset Pricing, Muhammed Yonac

Dissertations, Theses, and Capstone Projects

This dissertation consists of three essays in asset pricing with the common theme of return predictability.

Chapter 1: This chapter introduces the motivation, results, and structure of the dissertation.

Chapter 2: I examine the relation between the social ties between firms' headquarters locations and co-movements between their fundamentals and stock returns. The evidence indicates that firms in the same industry with socially connected locations exhibit co-movement in fundamentals and stock returns that exceed those without socially connected locations. However, the stock returns reflect the location information with a lag. To exploit this lagged relationship, we form portfolios that buy (sell) …

Essays On Impacts Of Women Empowerment On The Health Outcomes Of Children, Sagnik Das

Dissertations, Theses, and Capstone Projects

Chapter 1: Taking cognizance of the lack of representation of women in politics, the Indian government in 1993, enacted the 73rd constitutional amendment which led to a sudden increase in the representation of women in the local governments. Exploiting the exogenous variation in the timing of implementation of the 73rd amendment across the states, I study the spillover effects of this mandated empowerment of women on the health outcomes of children by using nationally representative survey data and employing a difference-in-difference estimation strategy. In this study, I find evidence of a positive impact of mandated women empowerment on the survival …

Credible Messengers: An Exploratory Analysis Of What Makes Them "Credible", Jason Szkola

Dissertations, Theses, and Capstone Projects

The use of credible messengers to deliver violence reduction programs has spread rapidly since it was first used in a criminal justice context by Cure Violence in 2006. Despite the rapid growth in the use of credible messengers and the accompanying evaluations of these programs, there is no clear operationalization of what a credible messenger is, aside from vague definitions contained in the evaluation literature. This research explores what it means to be credible from the perspectives of the Credible Messengers themselves. The research used a mixed method approach wherein qualitative interviews were used to identify traits that the Credible …
