Ornamentalism: Costuming And The Portrayal Of The Chinese Woman In Film, 20th-21st Century, Andrea Yepez

Dissertations, Theses, and Capstone Projects

This thesis aims to analyze the concept of “Ornamentalism,” a term created by Anne Anlin Cheng. In Ornamentalism (2019), Cheng proposes the term—a combination of Orientalism and ornament—as a new way to study Asiatic femininity. Cheng applies the term to a case study of the career of Anna May Wong, the first Asian-American actress to feature in Hollywood films. Throughout her career, which began in the 1920s, Anna May Wong held the status of it-girl and muse to designers such as John Galliano. However, Wong was also subjected to playing stereotypical Asian roles in films and was consistently the victim …

How The U.S. Mainstream Media Perpetuates Cis White Masculine Hegemony, Yelena Dzhanova

Dissertations, Theses, and Capstone Projects

The news is important because it helps individuals understand their place in the world and make the best decisions for themselves. Throughout its strong history and presence in the United States, the journalism industry has prided itself on delivering fact-based news using an objective framework, meaning that there is an expectation that journalists communicate the news impartially and without bias. Through an examination of gendered language and visual representations published in and by recent mainstream U.S. digital and print media outlets, this paper explains how the media plays a major role in the perpetuation of cis white masculinity. This paper …

Literature, Development, And The Reaches Of Literacy, 1979 To The Present, Stephen Tremaine

Dissertations, Theses, and Capstone Projects

In this study, I examine the twentieth century’s vast history of large-scale literacy campaigns and the imprints and legacies of those campaigns in literary texts from the global South. Literary texts by Mahasweta Devi, Nuruddin Farah, J. M. Coetzee, M. G. Vassanji, Abdulrazak Gurnah, and others provide compelling examples of narratives that foreground literacy - particularly its acquisition, loss, or redistribution in the lives, communities, and emerging independent nations in which these narratives take place. The second half of the twentieth century represents a global effort at the realignment of reading, writing, and power. In this moment, the authors at …

Synthesis Of Fluoroorganics And Applications Of Novel Fluorinated Building Blocks, Wei Wei

Dissertations, Theses, and Capstone Projects

Diastereoselectivity of fluorination of a carbanion alpha to a sulfone in enantiomerically pure N-Boc protected (R)- and (S)-2,2-dimethyl-4-((arylsulfonyl)methyl)oxazolidines has been studied. Fluorination proceeded with good to excellent diastereoselectivity, which was base-dependent and was highest with lithium diisopropylamide (LDA). Diastereoselectivity also depended on the aryl moiety of the aryl sulfone and was highest with benzothiazole-derived sulfones. Under basic conditions, epimerization at the C–F stereogenic center alpha to the sulfone has been achieved for the first time and proceeded with good to excellent diastereoselectivity, which was highest in the case of a benzothiazole sulfone and with a lithium base. …

Resource Management In Mobile Edge Computing For Compute-Intensive Application, Xiaojie Zhang

Dissertations, Theses, and Capstone Projects

With current and future mobile applications (e.g., healthcare, connected vehicles, and smart grids) becoming increasingly compute-intensive for many mission-critical use cases, the energy and computing capacities of embedded mobile devices are proving to be insufficient to handle all in-device computation. To address the energy and computing shortages of mobile devices, mobile edge computing (MEC) has emerged as a major distributed computing paradigm. Compared to traditional cloud-based computing, MEC integrates network control, distributed computing, and storage to customizable, fast, reliable, and secure edge services that are closer to the user and data sites. However, the diversity of applications and a variety …

The Rent Is Too Damn High:The Spatial And Longitudinal Dimensions Of Housing Affordability, Kasey Zapatka

Dissertations, Theses, and Capstone Projects

As the housing affordability crisis intensifies, I content that the spatial and longitudinal aspects of housing affordability are important dimensions of affordability. While much has been written about the sources and drivers of this new housing crisis, I investigate the impact of space, gentrification, and the life course on affordability patterns. I specifically address questions about the (1) role of space in shaping affordability patterns, the (2) impact of gentrification on neighborhood and household affordability, and (3) the trajectory of affordability over the life course. Broadly, I find that neighborhoods that are gentrifying in 2013 see increased affordability in 2019, …

The Bracero Program And The Exploitability Of Migrant Workers, Kayla E. Dantona

Dissertations, Theses, and Capstone Projects

This thesis explores the exploitability of migrants working in the United States. Historically, the United States government has emphasized the economic utility of migrant workers, while ignoring their basic human rights. Policymakers have viewed these people as a disposable work force and seek to control them by generating widespread fear of deportation, racialized segregation, discriminatory treatment, and with the help of governing and policing entities willing to turn a blind eye to these injustices, as long as they continue to profit financially.

This thesis will look at the Bracero Program with a historic lens to exemplify the system of exploitation …

Examining Factors Related To Tobacco Treatment Engagement Among Tobacco Dependent Black/African American; Hispanic/Latino Cancer Patients: An Analysis Of Memorial Sloan Kettering Cancer Center’S Tobacco Treatment Program, Gleneara E. Bates-Pappas

Dissertations, Theses, and Capstone Projects

Among patients diagnosed with cancer, persistent tobacco use is associated with adverse clinical outcomes such as worse treatment side effects, decreased effectiveness of cancer treatment (chemotherapy, radiotherapy, and surgery), all increasing risk of recurrence, second primary cancers, and poor survival. Despite the clinical importance of tobacco cessation in the context of high quality cancer care, engaging Black/African American and Hispanic/Latino cancer patients in tobacco treatment programs can be challenging. Prior studies with the general adult population demonstrate that Black/African American and Hispanic/Latino smokers are referred to and accept tobacco cessation treatment at lower rates compared to non-Hispanic White smokers. This …

Type Of Glossing Affects Cognitive Load And Retrieval Of Meaning During L2 Reading, Camilo Andrés Bonilla Carvajal

Dissertations, Theses, and Capstone Projects

The use of translation in language teaching has been a source of controversial debate, nevertheless, glossing—and, specifically, interlinear glossing—remains an understudied type of materials, despite having been used by learners and teachers of foreign languages since at least 1000 C.E. (Bata, Gwara & Porter, 1997). In the absence of a comprehensive literature review tracing the history of interlinear glossing, as well as the absence of enough empirical studies addressing the effect of glossing on cognitive effort in language learning, the present work aims at exploring the role of first language glossing in facilitating reading by describing the results of an …

Deconstructing Biopolitical And Performative Modes Of Gender In Spanish Science Fiction, Emma Navarro

Dissertations, Theses, and Capstone Projects

This thesis investigates the distinctly Spanish works of science fiction created by Pedro Almodóvar and Elia Barceló through biopolitical and feminist frameworks. Utilizing the theories of feminist philosopher Judith Butler and sociologist Jemima Repo, we uncover associations between the fictional and theoretical that have seldom been studied in conjunction. The paper aims to demonstrate Almodóvar and Barceló’s unique narratives free from the confines of an unwavering gender stratum while simultaneously revealing the deteriorative effects of gender as a control apparatus. Deeply influenced by the post-Franco Madrid Movida movement, these creators exemplify the feminist ideals emerging from that progressive time, rejecting …

The Numbers Don’T Lie: A Quantitative Examination Of Trauma Outcomes Among Black Homeless Women, Lisa Marie Persad

Dissertations, Theses, and Capstone Projects

Based on the extensive levels of trauma exposure and the need to provide effective mental health treatment for homeless women and their families, this dissertation was conducted to better understand trauma-related psychological distress and associated mental health outcomes among Black homeless women. More specifically, this study’s researcher examined a national sample of homeless women using three theoretical frameworks (Social Determinants of Health, Critical Race Theory, and Intersectionality), conducting a secondary analysis of the Mental Health Client Level-2018 dataset from the Substance Abuse and Mental Health Services Administration (SAMHSA), and employing hierarchical logistic regression modeling to examine the relative impact of …

Hands. Words. Mirrors. A Letter To My Mother., Iliana Emilia García

Dissertations, Theses, and Capstone Projects

My capstone project is a memoir of my mother in a letter format, where I tell my mother the story she forgot, who she was, where we were, and where we’re headed. After my mother was diagnosed with Alzheimer's in 2013, my focus on telling my family history shifted from research of the family to recovery. The loss of my mother's insight and recollections prompted a shift in the narrative. She, one of the main characters in my story, became my most important audience. In a photo album approach, I aim to rebuild what seems lost. I am keeping the …

Unlocking Potential: The School-To-Prison Pipeline For Students With Disabilities, Navena F. Chaitoo

Dissertations, Theses, and Capstone Projects

This research uses quasi-experimental, matched sampling to examine the school-to-prison pipeline for students with disabilities using data from the National Longitudinal Study of Adolescent to Adult Health. This study presents novel insights into an at-risk group that has faced disproportionate rates of school discipline and incarceration. The study finds school suspension to be associated with future involvement in the criminal legal system and lower educational attainment. Disability was not found to mediate the relationship between suspension and future involvement in the criminal legal system or the relationship between suspension and academic outcomes. However, disability was found to be a statistically …

Environmental Drivers Of Dispersal In Black-And-White Ruffed Lemurs (Varecia Variegata), Amanda Mancini

Dissertations, Theses, and Capstone Projects

Dispersal is a fundamental aspect of primates’ lives, influencing population connectivity through gene flow, driving community structure and assembly, and having important consequences for adaptation and speciation. Primates disperse within an environmental context, with both intervening and local environmental factors affecting the motivation, capacity, timing, and success of dispersal at all phases. Direct evaluations of primate dispersal are challenging given the rarity of dispersal events and the large distances that animals often settle from their departure site, therefore indirect measures– such as the use of population genetic data– are more common.

The field of landscape genetics enables researchers to combine …

A Stronger Strong Schottky Lemma For Euclidean Buildings, Michael E. Ferguson

Dissertations, Theses, and Capstone Projects

We provide a criterion for two hyperbolic isometries of a Euclidean building to generate a free group of rank two. In particular, we extend the application of a Strong Schottky Lemma to buildings given by Alperin, Farb and Noskov. We then use this extension to obtain an infinite family of matrices that generate a free group of rank two. In doing so, we also introduce an algorithm that terminates in finite time if the lemma is applicable for pairs of certain kinds of matrices acting on the Euclidean building for the special linear group over certain discretely valued fields.

The Impact Of Overseas Study Experiences On Chinese Students’ Attitudes Toward The United States, Xufeng Fang

Dissertations, Theses, and Capstone Projects

The extent to which overseas study experiences increase Chinese students’ positive attitude toward the United States has triggered debates because of Chinese government’ overwhelming influence on Chinese students studying overseas, the instability of U.S.-China relations and the especially complex characteristics of Chinese students’ attitudes themselves. I will use value theory, belief system theory, and self-categorization theory to explain the unstable character of these attitudes, and the important roles of values and identity that determine attitudes’ change. After making three key hypotheses based on these theories, this paper conducts a survey on three groups of Chinese students both in China and …

Diversity Still Matters: School-Level Racial Diversity, Poverty And Performance Of New York City Public Schools, Byunghwa Kim

Dissertations, Theses, and Capstone Projects

During the last few decades, schools in New York City (NYC) have experienced great demographic changes due to the massive influx of various ethnic and racial groups. Although the race and ethnicity makeup of NYC is 42% white, 29% Hispanic or Latino, 24% Black or African American and 14% Asian, 74% of Black and Hispanic students attend a school with less than 10 percent white students, while 34% of white students attend a school with more than half white peers. Also, more than 60% of Hispanic and Black students are attending schools where more than 75% of peer students experience …

Tgf-B Signaling Mechanisms In Caenorhabditis Elegans Response To Bacterial Pathogens, Emma J. Ciccarelli

Dissertations, Theses, and Capstone Projects

When exposed to infection, the nematode C. elegans mounts an innate immune response through secretion of antimicrobial peptides (AMPs). Different signaling pathways in the worm regulate release of these AMPs. One highly conserved pathway is the C. elegans BMP like pathway – regulated by the ligand DBL-1. The DBL-1 pathway is noted for its significant role in development but has also been shown to regulate many post-developmental processes within the worm, including the immune response. We are interested in determining how DBL-1 signaling can mediate a response specific to immunity, separate from its other functions in the worm. Through survival …

Chromatic Dissensus: An Otherwise Archive Of Natural Dyes, 1700–1856, Luke Church

Dissertations, Theses, and Capstone Projects

Chromatic Dissensus: An Otherwise Archive of Natural Dyes, 1750-1856 works from the premise that the absences regarding subaltern life structuring the colonial archive are an epistemological problem—that is, navigating the colonial archive requires an interrogation of the parameters and practices of knowledge formation. Building from recent scholarship in early American studies which details how eighteenth-century colonial knowledge developed out of an epistemic entanglement between British colonists, diasporic Africans, and indigenous Americans, my dissertation queries the overdetermination of colonial knowledge and subsequent occlusion of alternative parameters for knowing. Enlisting aesthetics, in its broad definition as the theorization of sense making, my …

Police Academy Attrition Rates: A Long-Term Analysis Of Female Candidates In California, Texas, Wisconsin, Arizona, And New Jersey, Shamus W. Smith

Dissertations, Theses, and Capstone Projects

Police agencies throughout the country still have an underrepresentation of women police officers. Research has shown that the benefits of hiring women police officers are many, as they have proven to be as competent as their male counterparts, less likely to use excessive force, can implement community-oriented policing, respond to calls for domestic violence effectively, bring about beneficial changes in policy for all agencies, and reduce the problems of sexual discrimination and harassment within an agency. Yet, the obstacles encountered for women are significantly different from their male counterparts. As such, this research uses secondary, non-identifiable data obtained from police …

Social Impacts Of Robotics On The Labor And Employment Market, Kelvin Espinal

Dissertations, Theses, and Capstone Projects

Robotics have been introduced into the workplace to perform tasks that human beings have traditionally fulfilled. Complementing or substituting human labor with robotics eliminates human involvement in functions attributable to hazardous environments, heavy lifting, toxic substances, and repetitive low-level tasks. On the other hand, they are meant to be more efficient and cost-effective, saving money, time, and labor. However, since the introduction of robotics in the workforce, societal opposition has been towards this branch of technology in fear of losing employment, wages, and purpose.

Previous studies have reported an overarching societal fear that adopting robotics in the workplace and industry …

Examination Of Korean Feminism From The Intersections Of Colonialism, Modernity, And Nationalism In Colonial Korea (1910–1945), Yae Hee Choi

Dissertations, Theses, and Capstone Projects

This thesis aims to investigate the politics of Korean feminism during the time of Japanese colonization (1910-1945) from the perspectives of colonialism, modernity, and nationalism. The study illustrates how Korean women perceived themselves in terms of individuals, colonial subjects, and Korean nationals during a period of significant societal changes. It also intends to broaden the boundaries of gender inquiries in colonial Korea, which often focus on binary constructions of Japanese repression versus national resistance. This study argues that a nationalist paradigm oversimplifies the intricate dynamics and varied experiences of colonized subjects, specifically women. The logic of nationalism places all forms …

Storytelling In Modernist Fiction: A “Method Of Presence”, Laura Malhotra

Dissertations, Theses, and Capstone Projects

This dissertation explores the relationship between narrative modes in cinema and literature and adopts the lineage laid out by Lukács that connects the oral tradition and epic poetry to the novel. I attach art cinema to this lineage and seek to justify its position as an equally significant medium representative of the age in which it is produced. This study aims to correct one established view of film, put forth by the Frankfurt School, of its low value as an art form and as a site of meaning. I compare the birth of literary modernism in Britain to the emergence …

American Eel (Anguilla Rostrata) And Other Fishes As Surveyed By Environmental Dna In The Bronx River And Hudson River Watershed, Sam C. Chin

Dissertations, Theses, and Capstone Projects

Mounting an effective response to the threats faced by freshwater fish may require expansions to aquatic biomonitoring in excess of what is feasible using the capture-based survey techniques currently relied upon by natural resource managers. Methods for analyzing environmental DNA (eDNA) are emerging as a minimally invasive and cost-effective approach for surveying fish and other organisms. By detecting taxon-specific DNA sequences recovered from environmental samples (e.g. water, sediment), eDNA methods are able to infer species presence from samples that can be collected rapidly with simple equipment. In many cases, eDNA detection rates of fish species have been shown to meet …

Mediated Locality: Assembling The Independent Music Scene In Brooklyn, New York, Frank Meegan

Dissertations, Theses, and Capstone Projects

This dissertation investigates how independent musicians, concert organizers, and other scene participants in Brooklyn, New York use digital technology and new media in their artistic practice. It is based on three years of participant observation in Brooklyn from 2016 to 2019, where I attended events at small venues like bars and DIY spaces, and interviewed musicians, concert organizers, independent label runners, and other scene participants. I also observed the online activity of musicians and organizers on public Facebook, Instagram, and Bandcamp pages. I argue that Brooklyn independent musicians use digital media, and are themselves mediated, as their activities at physical …

Dynamics In Designed Elastins And Enzymes, Jonathan M. Preston

Dissertations, Theses, and Capstone Projects

In this dissertation I present experimental results on the structure and dynamics of elastin, an elastomeric extracellular component in vertebrates that, in mammals, provides structure and elasticity to the circulatory system, lungs, skin and joints. These experiments, using a set of designed elastin like proteins with properties analogous to the natural protein, show that elastin is highly disordered and connect this disorder to its mechanism of assembly and elasticity. In addition, I also present preliminary work on imparting flexibility into a set of computationally designed metalloenzymes to broaden the range of catalytic activities they perform.

Indigenous Performances In Contemporary Indian Urban Public Theatres: Coloniality, Globalization, And The State, Mayurakshi Sen

Dissertations, Theses, and Capstone Projects

Indigenous Performances in Contemporary Indian Urban Public Theatres: Coloniality, Globalization, and the State examines the aesthetic and political dimensions of contemporary public theatres in the major Indian cities of Kolkata, Mumbai, and Delhi, with a special focus on the utilization of India’s indigenous precolonial (or extra-colonial) classical, regional, and folk performance forms, elements, and repertoires in such urban practice. Through dramaturgical, ethnographic, and archival analyses, this dissertation studies significant contemporary productions from representative urban Indian theatre groups, including Nandikar, Rangakarmee, and Padatik in Kolkata; the Indian People’s Theatre Association, Mumbai, Ekjute, and Rangshila in Mumbai; and Circle Theatre Company and …

Speakers And Addressees As Creative Interpreters, Svitlana Novikova

Dissertations, Theses, and Capstone Projects

Philosophers in the past have argued that the way the word “interpret” is used within creative fields unhelpfully conflates the notions of deriving and creating content. Arguing against this, I propose that the blurring of these two notions accurately describes how addressees interpret speakers, performers interpret scores, and audiences interpret art and music. Even speakers can be described as creative interpreters in this sense, as articulating a thought into an utterance requires an interpretive effort. I develop the idea that interpreting straddles the divide between deriving and creating content within the framework of the ostensive-inferential communication proposed by Sperber and …

One-Loop Corrections To Dihadron Production In Dis At Small X, Filip Bergabo

Dissertations, Theses, and Capstone Projects

We calculate the one-loop corrections to dihadron production in Deep Inelastic Scattering (DIS) at small x using the Color Glass Condensate formalism. We show that all UV and soft singularities cancel while the collinear divergences are absorbed into quark and anti quark-hadron fragmentation functions. Rapidity divergences lead to JIMWLK evolution of dipoles and quadrupoles describing multiple-scatterings of the quark anti-quark dipole on the target proton/nucleus. The resulting cross section is finite and can be used for phenomenological studies of dihadron angular correlations at small x in a future Electron-Ion Collider (EIC).
