Randomized Search Of Graphs In Log Space And Probabilistic Computation, Wen-Ju Cheng

Dissertations, Theses, and Capstone Projects

Reingold has shown that L = SL, that s-t connectivity in a poly-mixing digraph is complete for promise-RL, and that s-t connectivity for a poly-mixing out-regular digraph with known stationary distribution is in L. Several properties that bound the mixing times of random walks on digraphs have been identified, including the digraph conductance and the digraph spectral expansion. However, rapidly mixing digraphs can still have exponential cover time, thus it is important to specifically identify structural properties of digraphs that effect cover times. We examine the complexity of random walks on a basic parameterized family of unbalanced digraphs called Strong …

The Gawain-Poet And The Textual Environment Of Fourteenth-Century English Anticlericalism, Ethan Campbell

Dissertations, Theses, and Capstone Projects

The 14th-century Middle English poems Cleanness and Patience, homiletic retellings of biblical stories which appear in the same manuscript as Pearl and Sir Gawain and the Green Knight, offer moral lessons to a general Christian audience, but the introduction to Cleanness, with its reference to men whom "prestez arn called," suggests that a central feature of their rhetoric is anticlerical critique. Priests do not appear as exemplars but as potentially filthy hypocrites who inspire God's harshest wrath, since their sins may contaminate Christ's body in the Eucharist.

Using Cleanness's opening lines as a guide, this dissertation …

Todesfuge, Casey Hale

Dissertations, Theses, and Capstone Projects

Todesfuge (2008-2010) is a setting, for tenor and chamber orchestra, of Paul Celan's poem of the same name. Celan wrote his landmark work on the Holocaust in the years after he himself was freed from internment in a Romanian forced labor camp in 1944, though its imagery is drawn from accounts of the death camps in Poland. From the outset, I was ambivalent about setting this text to music, but felt compelled, and my response was to frame it with idiomatic references to German music from Wagner to Weill, exploring the discomfort of using aesthetic artifice to represent unspeakable atrocities. …

The Historic Inability Of The Haitian Education System To Create Human Development And Its Consequences, Patrick Michael Rea

Dissertations, Theses, and Capstone Projects

This study aims to evaluate the role that a lack of literacy and education has played in Haiti's historic and presently low level of human development. The pedagogical philosophies of two educationists, Paolo Friere and Maurice Dartigue, are used throughout the study as lenses from which to read and interpret the history of Haitian education -its many failed attempts, and recurrent challenges- in creating a literate and educated population. The author concludes that mass literacy is prerequisite if the Haitian people are to achieve self-realization and actualization, which essentially equates to what the United Nations Development Program calls "Human Development". …

Variable Pressure Nuclear Magnetic Resonance Studies Of Ionic Liquids And Electrophoretic Probe Design, Armando Julio Rua

Dissertations, Theses, and Capstone Projects

Energy storage materials play a key role in, efficient, clean, and versatile use of energy, and are crucial for the exploitation of renewable energy. The improve efficiency of energy use stimulates the development of energy storage such as batteries or super capacitors, toward higher power and energy density, which significantly depends upon the advancement of new materials used in these devices. The new materials need better understanding and description in the electrochemical properties. Nuclear Magnetic Resonance (NMR) has been an important tool in the characterization of ionic liquids and solids. The measurements of the relaxation times and the diffusion coefficient …

Standard Deviations: Reality, Reproducibility, And Politics In Performance Art Since 1989, Jonah Westerman

Dissertations, Theses, and Capstone Projects

Performance art is conventionally seen as having a privileged relation to reality because of the way it insists on the immediate experiences of specific human bodies, the full depth of which can never be adequately reproduced or captured. This understanding of performance as accessing authenticity through ephemerality has long made it a stage for artistic and political subversion. Since the early 1990s, however, a group of European artists responding to processes of globalization that have changed the nature of political economy--the demise of the Soviet Union, NAFTA, and new regulations concerning trade and travel in the E.U.--have developed performance strategies …

Essays On Savings Behavior Of Low-Income Households In Colombia, Luz M. Salas

Dissertations, Theses, and Capstone Projects

I designed and implemented a Randomized Controlled Trial to study whether relatively simple modifications to how a commitment savings product was framed and labeled could affect savings accumulations and other outcomes of low-income individuals in newly formed Village Savings and Loan Associations (VSLAs) in Colombia. Motivated by hypotheses from behavioral economics, the experiment tests hypotheses that behavioral responses should vary depending on whether subjects are led to label and create `mental savings accounts' in private or public ways. Individuals in the private-labeling treatment groups were led to label their savings as earmarked for a particular purpose and to state savings …

The Role Of The Striatal Neuropeptide Neurotensin In The Methamphetamine-Induced Neural Injury In Mice, Qingkun Liu

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) is a widely abused psychostimulant that induces neurotoxicity to several brain regions, including the striatum. Similar to dopamine (DA) in chemical structure, METH can be transported into DA pre-synaptic terminals, evoking the neurodegeneration in DA terminals and post-synaptic striatal neurons. Despite the critical role of DA in METH-induced neurodegeneration, no pharmaceutical therapeutics has been approved for these conditions. It is therefore essential to investigate the endogenous factors regulating the dopaminergic system. The neuropeptide neurotensin has emerged as a potential modulator of METH-induced striatal neurodegeneration mainly due to its intimate interactions with dopamine in the striatum.

In this study, …

Control Of Exciton Photon Coupling In Nano-Structures, Xiaoze Liu

Dissertations, Theses, and Capstone Projects

In this thesis, we study the interaction of excitons with photons and plasmons and methods to control and enhance this interaction. This study is categorized in three parts: light-matter interaction in microcavity structures, direct dipole-dipole interactions, and plasmon-exciton interaction in metal-semiconductor systems.

In the microcavity structures, the light-matter interactions become significant when the excitonic energy is in resonance with microcavity photons. New hybrid quantum states named polariton states will be formed if the strong coupling regime is achieved, where the interaction rate is faster than the average decay rate of the excitons and photons. Polaritons have been investigated in zinc …

The Presentation Of Trans In Everyday Life: An Autoethnographic Exploration Of Gendered Performance, Elijah C. Nealy

Dissertations, Theses, and Capstone Projects

The life experiences of transgender men are an understudied area in social work research. Given the negative experiences many transgender men have utilizing the medical and social service systems, greater understanding is needed about how these men negotiate their identities in an array of relational contexts. This dissertation uses autoethnography to explore how one transgender man navigates his identity as a man, father, and social work professional.

Viewed through the theoretical frame of Erving Goffman's work, and in dialogue with masculinities studies and queer theory, this study finds that trans men are continually negotiating their identities in varying relational contexts, …

Ralph Shapey And The Search For A New Concept Of Musical Continuity, 1939-66, Barry Wiener

Dissertations, Theses, and Capstone Projects

This dissertation creates a narrative for the stylistic development of the American composer, Ralph Shapey, during the first half of his career. Shapey's music represents a fusion of Schoenbergian metamorphic process and Varèsian stasis, methods for the creation of musical continuity that are usually considered incompatible. I show how Shapey formulated his compositional techniques, influenced by his teacher, Stefan Wolpe, and his friend, Edgard Varèse.

Shapey's interest in the music of Schoenberg was mediated through the prism of Wolpe's musical ideas. Wolpe used unordered pitch-class sets to present the aggregate in his music, and avoided Schoenberg's neo-classic and neo-baroque forms …

Self-Referentiality In Constructive Semantics Of Intuitionistic And Modal Logics, Junhua Yu

Dissertations, Theses, and Capstone Projects

This thesis explores self-referentiality in the framework of justification logic. In this framework initialed by Artemov, the language has formulas of the form t:F, which means "the term t is a justification of the formula F." Moreover, terms can occur inside formulas and hence it is legal to have t:F(t), which means "the term t is a justification of the formula F about t itself." Expressions like this is not only interesting in the semantics of justification logic, but also, as we will see, necessary in applications of justification logic in formalizing constructive contents implicitly carried by modal and intuitionistic …

Bicultural Social Identity: Do Biculturals Assess Workplace Deviance Differently Across Different Ethnicities?, Andy Y. Chiou

Dissertations, Theses, and Capstone Projects

Research on biculturals has informed us much regarding their cognition and identity integration, however little as to the bicultural perception of in- and out-groups, and whether it can be primed. I examined this question in a workplace setting using the black sheep framework, specifically: Given the activation of one of a bicultural's specific cultural identities, will he or she allocate punishment to deviant employees of different cultural backgrounds differently based on whether he or she views them as an in-group or out-group member? In Study 1, I show that Asian-American biculturals do assess deviant employees of different cultural backgrounds differently …

Planetary Improvement: Discourses And Practices Of Green Capitalism In The Cleantech Space, Jesse Adam Goldstein

Dissertations, Theses, and Capstone Projects

There is money to be made in saving the planet. A whole host of actors, such as investors, entrepreneurs, engineers, and policy makers have mobilized around our ecological problems, seeking to innovate new `green' and `clean' technologies that can serve a rapidly changing environment. The presumption that such technologies are both necessary and necessarily profitable anchors visions of a `green' capitalism that can and must be brought into existence.

However, just as free markets have never been all that free, why should we presume that green capitalism would be all that green? Instead of attempting to arbit whether or not …

Paleoecology Of Late Cretaceous Methane Cold-Seeps Of The Pierre Shale, South Dakota, Kimberly Cynthia Handle

Dissertations, Theses, and Capstone Projects

Most investigations of ancient methane seeps focus on either the geologic or paleontological aspects of these extreme environments. In contrast, this thesis encompasses both disciplines to evaluate the paleoecology of these systems with greater detail than previously published either within the Western Interior Basin or elsewhere. This thesis addresses the following questions: 1) Are the changes in mineralogy of a seep discernable and predictable as a seep shifts from a clay-based environment to a carbonate-based environment? 2) What are the foundation organism(s) of Late Cretaceous methane cold-seeps? 3) Is there a correlation to the mineralogic changes and shifts in community …

Verbal Behavior In Individuals With Generalized Anxiety Disorder And Depressive Disorders, Tzachi Slonim

Dissertations, Theses, and Capstone Projects

Generalized Anxiety Disorder (GAD) and clinical depression are both internalizing disorders characterized by sustained negative affect and have mainly been studied utilizing either self-report or physiological measures. Fewer studies have focused on behavioral indices of these disorders, and little is known about their overlapping and distinct linguistic features. The present research examined the above gap in two separate studies. Study 1 synthesized previous efforts made to study the linguistic features of individuals with depression. Previous investigations found that depressed individuals evidence high proportions of I-words, high proportions of negatively-valenced words, low proportions of positively-valenced words, and high proportions of cognitive …

Reconstructing The Nation: African American Political Thought And America's Struggle For Racial Justice, Alex Zamalin

Dissertations, Theses, and Capstone Projects

This dissertation examines how twentieth-century African American intellectuals engaged American political cultural beliefs central to American identity. A prominent argument of American political thinkers has been that the liberal-democratic ideals of freedom, equality, representative government, the rule of law, tolerance and civic obligation are what make Americans a unique people. From the immediate aftermath of the Second World War to the late twentieth-century such an argument provided American politicians, social movements and intellectuals a strong justification for divergent political claims, from Cold War warriors calling for the containment of Soviet Communism, to Civil Rights activists calling for racial integration to …

Straight Record And The Paper Trail: From Depression Reporters To Foreign Correspondents, Magdalena Bogacka-Rode

Dissertations, Theses, and Capstone Projects

Straight Record and the Paper Trail: From Depression Reporters to Foreign Correspondents engages with Martha Gellhorn's The Face of War (1959), Virginia Cowles' Looking for Trouble (1941) and Josephine Herbst's The Starched Blue Sky of Spain and Other Memoirs (1991) as documentaries of struggle. Documentary as a mode of writing and image making reveals dissonance, contradictions and varied perspectives which undermine the official historical record. The three writers, I argue, by republishing their Spanish Civil War (SCW) journalism in book form intended to set their record straight. This was motivated by their commitment to the 1930s struggle and the need …

Science Identity Transformations Through Place-Based Teaching And Learning In The Natural World, Amy Defelice

Dissertations, Theses, and Capstone Projects

This dissertation includes three main components related through a sociocultural lens of identity transformation. The first component describes the Field Studies program for ninth grade students at Brooklyn Academy of Science and the Environment (BASE High School), and explores how outdoor settings and place-based pedagogies can be used to enhance urban students' science identities. Student researchers took digital photographs of their Field Studies experiences and met in cogenerative dialogues with me, their teacher, where we shared our reflections. The second component explains students' experiences and reactions to a week-long place-based geoscience program held over spring break at Prospect Park. This …

Factlessness & Faultlessness: Individual Differences & Dimensions Of Philosophical Dispute, Geoffrey Scott Holtzman

Dissertations, Theses, and Capstone Projects

This project addresses the question of why philosophical disputes persist, and tackles the problem of how we might better approach them. I demonstrate empirically several ways in which personality, gender, and other factors are associated with specific philosophical beliefs. Typically, one might assume that these individual difference factors are irrelevant to philosophy, and can only serve to bias philosophical disputants. Against this view, I present four case studies, which collectively highlight the different ways in which individual differences in lived experience may be inseparable from philosophical concepts themselves.

A Gift We Can't Keep Giving: An Analysis Of The Prevalence And Consequence Of Educators' Unpaid Labor, Jared Martin Hanneman

Dissertations, Theses, and Capstone Projects

Unpaid labor by educators is an important topic of social inquiry. With over half of all urban teachers leaving the profession within five years, it is of vital importance to examine the current U.S. educational system and take steps in minimizing the teacher burnout and attrition that is so costly to both students and the educational institutions. Most of the previous literature on unpaid labor focuses on domestic labor in the home rather than work performed by an employee above and beyond their ordinary contractual obligations - either by arriving early, staying late, or bringing work into the home. With …

Biological Motion Processing In Typical Development And In The Autism Spectrum, Aaron Krakowski

Dissertations, Theses, and Capstone Projects

Biological motion (BM) analysis and interpretation is a fundamental process of human neurocognition that has been only minimally explored neurophysiologically. In addition to its importance in understanding the underlying roots and development of social cognition, BM processing is a prime candidate domain for exploring the underlying etiology of social cognitive disorders such as the autism spectrum.

In an initial experiment, typical adults observed BM point-light displays of a human actor (UM) as well as their spatially scrambled counterparts (SM), in both an unattended distractor task as well as an explicit attention task. Results showed a neurophysiological response manifested as three …

An Innovative Ran Architecture For Emerging Heterogeneous Networks: "The Road To The 5g Era", Shahab Hussain

Dissertations, Theses, and Capstone Projects

The global demand for mobile-broadband data services has experienced phenomenal growth over the last few years, driven by the rapid proliferation of smart devices such as smartphones and tablets. This growth is expected to continue unabated as mobile data traffic is predicted to grow anywhere from 20 to 50 times over the next 5 years. Exacerbating the problem is that such unprecedented surge in smartphones usage, which is characterized by frequent short on/off connections and mobility, generates heavy signaling traffic load in the network "signaling storms". This consumes a disproportion amount of network resources, compromising network throughput and efficiency, and …

Essays On Robust Estimators For Non-Identically Distributed Observations In Spatial Econometric And Time Series Models, Suleyman Taspinar

Dissertations, Theses, and Capstone Projects

This thesis proposal consists of three essays on the estimation methods and applications of spatial econometric models and one essay on the generalized autoregressive conditionally heteroskedastic (GARCH)-type models in financial time series. The first essay discusses the heteroskedasticity robust generalized method of moments estimator (RGMME) for the spatial models that allow for spatial dependence in both the dependent variable and the disturbance term (SARAR(1,1)). First, we show that the maximum likelihood estimator (MLE) is generally inconsistent in the presence of unknown heteroskedasticity. Then, we extend robust GMM approach in Lin and Lee (2010) to SARAR(1,1). The large sample properties are …

Underprivileged Children In Port-Au-Prince, Haiti: Hearing And Academic Performance Of Children In Public Schools In Port Au Prince, Talia Meisel

Dissertations, Theses, and Capstone Projects

Hearing loss is estimated to affect more than 360 million people worldwide, 32% of whom are children. Children with hearing loss tend to develop compromised communicative abilities and also have been found to perform more poorly academically than their normal hearing peers. Because of the lack of medical care, children in third world countries are expected to have more difficulty hearing and learning in a classroom setting than children in first world countries due to higher incidences of conductive pathology. The purpose of this study is to assess the hearing ability of underprivileged children in kindergarten and primary schools in …

Formative Assessment Through Written Feedback: Examining Elementary School Teachers' Written Feedback Beliefs And Practices, And The Effect Of Models On Written Feedback, Caterina Almendral

Dissertations, Theses, and Capstone Projects

The current study explored three main aspects relating to the use of written feedback as a formative assessment tool: the types (form or content) of written feedback provided by elementary school teachers and the levels (task, process-Self-Regulation) at which those types of feedback are provided; whether elementary school teacher beliefs about written feedback principles and their own written feedback practice correspond to the actual written feedback they provide; and whether exposure to a model of written feedback influences teacher written feedback practice.

Data were collected from 188 elementary school teachers spirally assigned to five groups (four treatment, one control). Treatment …

Latinas Converting To Islam In New York: Habitus’ Influence In Modern Identity Formation, Amalia Alonzo

Dissertations, Theses, and Capstone Projects

This paper explores the topic of religious conversion in relation to Pierre Bourdieu's theory of habitus, with a focus on Catholic Latina converts to Sunni Islam. Bourdieu suggests that these types of religious choices are not choices at all, but predetermined by an individual's history, culture, and setting. That is, an individual already has dispositions that are taken for granted. While this study's participants report that Islam is a new religion for them and not a continuation of their Catholic faith (as habitus would suggest,) this study shows that these converts retain dispositions that are consistent with their previous religious …

Interactions Of Eukaryotic Translation Initiation Factors And 3' Untranslated Region Of Barley Yellow Dwarf Virus Mrna During Protein Synthesis: A Study Of Equilibrium Binding, Kinetics And Thermodynamics, Bidisha Banerjee

Dissertations, Theses, and Capstone Projects

Eukaryotic initiation factor (eIF) 4F binding to mRNA is the first committed step in cap-dependent protein synthesis. Barley Yellow Dwarf Virus (BYDV) employs a cap-independent mechanism of translation initiation which is mediated by a structural element BTE (BYDV translation element) located in the 3’ UTR of its mRNA. eIF4F bound the BTE and a translational inactive mutant with high affinity; thus questioning the role of eIF4F in translation of BYDV. To examine the effects of eIF4F in BYDV translation initiation, BTE mutants with widely different in vitro translation efficiencies ranging from 5-164% compared to WT were studied. Using fluorescence anisotropy …

Minorities' Perceptions Of Minority-White Biracials: The Role Of Identification For Cognitive, Affective, And Behavioral Responses, Sabrica Barnett

Dissertations, Theses, and Capstone Projects

Research on intergroup relations has a rich history in social psychology, with scholars devoting a considerable effort investigating factors that influence stereotyping, prejudice and discriminatory behavior. The results of these studies suggest that individuals' cognitions, affect, and behaviors are affected by their own group memberships as well as the groups to which others belong. People generally view the groups that they belong to (their ingroup) positively, and view the groups that others belong to (outgroups) stereotypically (Tajfel & Turner, 1986). However, much of the research on social identification and subsequent perceptions has focused on socially distinct groups rather than groups …

Reclaiming Space: Buildings In Modernist Literature And Film, Sreenjaya Ria Banerjee

Dissertations, Theses, and Capstone Projects

This dissertation argues that modernists like Virginia Woolf, T. S. Eliot, and Alain Resnais construct literary and filmic works that rely on interruptions and elliptical narration to gesture towards an aesthetics of modernity that counters the interest in monoliths concurrently shown by architectural modernism. This is particularly evident in the context of the war memorial, where regimented public memory is countered by the artistic works discussed through their emphasis on private memorials that are changeable, contingent, and mutable. This is a fundamentally altered vision of twentieth century modernity than that embraced by the architectural mode.
