Reducing Arsenic Exposure From Private Well Water In The United States: The Use, Effect, And Potential Of Testing Requirements, Sara Flanagan

Dissertations and Theses

Over 45 million Americans drink from unregulated private well water of unknown quality. Arsenic is the most concerning groundwater contaminant for health because of its toxicity and widespread natural occurrence. Most residential wells in arsenic-affected areas have not been tested for arsenic; the success of community programs and efforts to motivate testing is limited by a range of psychological, situational, and socioeconomic barriers. However, testing only acts as screening and does not reduce exposure without effective and consistent actions to follow. Given the limitations in relying on individual well owners to be aware, willing, and capable of testing their water, …

Acceptability Study And Pilot Rct Of A Guide To Understanding Reproductive Health For Ladeez (Gurhl) Code: An Hiv Risk Reduction App Intervention For Black And Latina Young Women In New York City, Sonia K. Gonzalez Gladstein

Dissertations and Theses

Background: Young Black and Latina women suffer from higher sexually transmitted disease (STD) incidences than White women, increasing their susceptibility to contracting human immunodeficiency virus (HIV). The adoption and widespread usage of mobile devices has contributed to the public’s ability to access available information at all hours, including information on sexual and reproductive health (SRH). Despite a growing body of mobile health literature, there is limited understanding of how mobile-based sexual and reproductive health interventions for use by young adult Black and Latina women could improve sexual health knowledge and connection to clinical care.

Methods: This pilot randomized controlled trial …

In a city that never sleeps, NYC, also called the big apple, there is the largest population in the United States with close to 9 million people. In addition, it is the second wealthiest city in the world according to ranking by gross domestic product (GDP). Being such a densely populated city, people cannot only rely on their vehicles as the only source of commute. The alternative is to use mass transit. New York City Transit (NYCT) is the largest mass transit system that offers commuting services via subway or buses. More than half of the population rely on mass …

Creator And Creation: Artistic Development In Herman Melville’S Pierre; Or, The Ambiguities And James Joyce’S A Portrait Of The Artist As A Young Man, Magdalena M. De La Cruz

Dissertations and Theses

This study focuses on the primary protagonists of Herman Melville’s Pierre; or, the Ambiguities (1852) and James Joyce’s A Portrait of the Artist as a Young Man (1916), Pierre Glendinning and Stephen Dedalus, as well as Isabel Banford, a supporting character in Melville’s novel, to illustrate how the tensions of contemporary society have a direct influence on the artist-hero’s representations and perspectives on self-realization. This thesis will draw on the major concepts of the artist and artist fiction as put forth in Otto Rank’s Art and Artist (1916), Herbert Marcuse’s “Der Deutsche Künstlerroman” (“The German Artist Novel”, 1922), and Maurice …

Evangelizing Neoliberalism Through Megachurches In Latin America And The United States, William O. Collazo

Dissertations and Theses

The most prominent and influential feature of worldwide Evangelicalism, is the megachurch. In Latin America megachurches have proliferated and grown in political influence when they first came into contact with neoliberalism during Pinochet's dictatorship in Chile. As Latin America's poor first migrated out of rural areas into Latin American cities, then north, to the United States, they have brought with them their religion. Increasingly, this religion is Protestant, evangelical, and for many, it is Pentecostalism. Misunderstood by the early literature on Pentecostalism, is the strain of neoliberalism that has become infused in the religion's most powerful institution - the megachurch. …

From Amherst To The Other Side: The Integration Of Emily Dickinson Into The Italian Consciousness, Mia Jozwick

Dissertations and Theses

At the beginning of the twentieth century, Emily Dickinson’s poetry appeared in Italy in two key forms: anthologized alongside other American authors and in select translations by prominent Italian intellectuals including poet Eugenio Montale and writer Emilio Cecchi. Dickinson was both touted as one of the great American writers, but also kept as somewhat of an underground poet who spoke to a specific literary identity in Italy. The cross-hairs of history brought together increased knowledge of Dickinson’s poetry just as Mussolini and his fascist agenda threatened the influence of literature whether homegrown or international. What materialized was a dynamic in …

Electrode And Headgear Design For Accurate Tdcs, Henry Bernstein

Dissertations and Theses

Stimulating the brain with a low current that is focused on specific regions of the brain has been shown to modify brain function and treat various neurological diseases. Transcranial direct current stimulation (TDCS) has been an effective and life changing alternative treatment for a vast range of neurological conditions including depression, epilepsy, stroke rehabilitation, addiction and chronic pain but only if it is administered correctly. During TDCS, a weak constant current is applied to precise locations on the scalp to modulate brain activity. Those locations can be determined by the cumbersome 10-20 EEG measurement system, transcranial magnetic stimulation or neuronavigation. …

Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack

Dissertations and Theses

Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating Wnt …

A Convergence Of Surrealism And Realism: Why Spirituality, Folklore, And The Supernatural Saturate The Work Of Toni Morrison, Kevon K. Harvey

Dissertations and Theses

This paper will analyze how Toni Morrison blends surrealistic elements into the recognized realism of her text by crafting various paradoxes within her work. Using three of Morrison’s books: Sula, Song of Solomon, and Beloved, I will examine how each book ties a specific surrealistic component, as well as an equally relevant realistic element that will aid in the construct of a figurative bridge between the cultural past and present for African Americans. Moreover, I will discuss how the use of the surreal in Morrison’s work represents a dive into African traditions. Formed as a direct result of slavery, …

Evolution Of Floral Morphology And Symmetry In The Miconieae (Melastomataceae), Maria Gavrutenko

Dissertations and Theses

Analyses of evolution of floral morphology and symmetry broaden our understanding of the drivers of angiosperm diversification. Integrated within a flower, labile floral characters produce different phenotypes that promote variable interactions with pollinators. Thus, investigation of floral evolution may help infer potential historic transitions in pollinator modes and ecological pressures that generated present diversity. This study aims to explore morphological evolution of flowers in Miconieae, a species-rich Neotropical tribe within family Melastomataceae. Despite a constrained floral plan, Melastomataceae manage to achieve a variety of floral traits appealing to diverse pollinator types, with majority of the species requiring specialized “buzz pollination” …

From Fear To Reverie: Incidents In Isolation In The American Wilderness, Serhiy Metenko

Dissertations and Theses

This thesis looks at Nineteenth Century American adventure narratives to examine the role of the wilderness. This thesis centers on a motif of isolated characters in the wilderness and analyzes the various techniques nineteenth-century authors use to project the psyche of their characters. The selected Nineteenth Century authors: Washington Irving, Charles Brockden Brown, Edgar Alan Poe, Harriet Spofford, Nathaniel Hawthorne, and Herman Melville root America’s identity in the wilderness. They emphasize its power on the human psyche as positive, restorative, inward-looking, and divine. This thesis argues that these authors portray the wilderness as a protagonist that needs to be preserved …

Writing Indigenous Identity In Herman Melville And Joseph Conrad's Polynesian And Malay Archipelago Novels, Catherine L. Black

Dissertations and Theses

The thesis of this paper is that cross-cultural writing can be done with the right methods of communication, such as engaging narrator and education—or simply sensitive, imaginative writing. Herman Melville and Joseph Conrad’s five books set in the Polynesian and Malay Archipelagos—Typee and Omoo and the Malay Trilogy (Almayer’s Folly, An Outcast of the Islands, and The Rescue)— are used as master models of how to write indigenous characters with rich characterization in pivotal roles, even circa 1846 and 1896. The unique perspective and technique by which they did this is explored, a technique and perspective not …

The Famished Road: Oil Dependency And Socioeconomic Underdevelopment In The Niger Delta, Nelson Caban

Dissertations and Theses

This thesis examines the social and political relationships between indigenous communities within the Nigerian Delta region and the Federal government regarding the management of petroleum resources and its implication for the general socioeconomic development of the Nigerian State. It investigates the correlation between the broader issues of sociocultural sovereignty, representation of ethnic minorities in the body politic and infrastructural development of the country. Furthermore, the thesis explores trends such as the development of native-led cultural institutions that foster the continuation of cultural praxis through the theoretical tropes of Globalization and Modernization.

The Effect Of Stress Induced Premature Senescence On The Expression Of Heterogeneous Ribonucleoieoprotein, Yuriy Pechenyy

Dissertations and Theses

The role of heterogeneous nuclear ribonucleoproteins (hnRNP) in cellular senescence is yet to be defined. Cellular senescence is a terminal growth arrest in somatic cells. It is thought to be the consequence of telomeric shortening that acts as a DNA damage signal. Conversely, cells induced into premature senescence (SIPS) by oxidative stress, is independent of telomere attrition. Premature senescence has been proposed to be physiologically relevant as it can be induced by treatment with chemotherapeutic agents. In particular, we are studying the roles of hnRNP A1 and A2 in the maintenance of the senescence phenotype. hnRNPs are a family of …

Convective Transport Of Tropical Marine Boundary Layer Species Into The Upper Troposphere And Relation To Species Lifetime: In Situ Measurements And Global Model Simulation, Sofia M. Chelpon

Dissertations and Theses

This study investigates the influence of tropical deep convection on distribution of trace gasses in the tropical upper troposphere (UT) using data from the Convective Transport of Active Species in the Tropics (CONTRAST) Experiment conducted over the tropical western Pacific during January and February of 2014. Fifty-five chemical species measured during the CONTRAST campaign are analyzed with lifetimes ranging from less than a day to several years. The vertical profiles of these species suggest that they fall into three main groups delineated by their lifetime: 1) very long-lived trace gases demonstrating a nearly constant vertical structure, 2) intermediate lifetime species …

“Better Unmentioned:” An Assessment Of Reagan Administration Aid To Pakistan, Panama, And Zaire., Charles G. Sherrard

Dissertations and Theses

Abstract.

During the Cold War, the Reagan administration justified American support to the Noriega dictatorship in Panama, the Mobutu dictatorship in what was then called Zaire, and the regime of Zia ul-Haq in Pakistan, by stating that it was necessary to overcome the Soviet Union. While the alliances with these regimes did help to bring about the collapse of the Eastern Bloc in 1989, each of these three regimes also acted against US interests via the promotion of drug smuggling or militancy, or forging other alliances with powers potentially hostile to American interests .[1] However, Soviet quagmires in these …

Mexican Technoscientific Arts, 2000-2015: Art And Science, Machine Inventions, And Political Ecologies, Carlos R. Guzman

Dissertations and Theses

In the last decades, several artists have engaged directly with emerging digital technologies and science, the so-called new media arts. For the past fifteen or twenty years, such practices have experienced a paradigmatic transformation in Mexico, particularly in the capital. They have shifted from peripheral to mainstream, from contingent to ubiquitous, and from underground/experimental to official and governmentally funded.

This thesis explores the development of technoscientific arts in Mexico, its evolution, main artists, and institutions. It focuses on specific technoscientific artistic projects developed in Mexico between 2000 and 2015 by artists like Tania Candiani, Gilberto Esparza, Iván Puig, and Ale …

Mild Traumatic Brain Injuries And Their Implications On Changes In Event Related Potentials: A Look Into Visual Gating (P50), Katelynn M. Kozak

Dissertations and Theses

Concussions are a prevalent injury that affect a wide range of individuals. Commonly seen amongst individuals who play contact sports, there are many underlying factors that doctors and clinicians have yet to understand which include properties such as proper diagnosis standards or lasting impacts. In this study, we look at those impacts by using electroencephalographic (EEG) measures to study the changes in event related potentials (ERPs) associated with sensory gating and how this cognitive property is affected in those who have a self-reported concussion. Here we show that a visual attention and gating mechanism exists in both populations (control and …

The Geographic Mosaic Of Wolbachia Infection In Melanitis Leda Butterfly Populations, Brandon E. Latorre

Dissertations and Theses

Insects are the most species-rich multicellular taxon on the planet, and it is estimated that more than half of all insect species are infected with the endosymbiont Wolbachia. This bacterium can manipulate the reproduction of its host and potentially affect host evolution. Most surveys investigating patterns of Wolbachia infection in nature sample limited numbers of individuals; population-level investigations into geographic differences in infection status that might affect host evolution are few. To investigate geographic variability among populations of a single species, we assayed 133 Melanitis leda butterflies (Lepidoptera: Nymphalidae: Satyrinae) for Wolbachia infection collected throughout its range in the …

Bone Marrow Derived Progenitor Cells And Their Contributions To The Thymic Stroma, Mohammed Hoque

Dissertations and Theses

The thymus serves as the primary lymphoid organ responsible for the development and selection of a self-tolerant T cell repertoire. In paradox to its critical functions for the adaptive immune response, the thymus undergoes a profound age associated decline beginning in early adult life resulting in significant decline in T-cell function.Thymic epithelial cells (TECs) are the most critical component of the thymic microenvironment and undergo rapid turn-over, so understanding the cellular mechanisms responsible for the maintenance of TEC number and organization will be critical in counteracting age associated involution, particularly in cancer patients, due to enhanced degeneration in response to …

Evangelical Dictatorship Driving The Guatemalan Civil War: Reconsidering Ríos Montt, The “Savior Of La Nueva Guatemala”, Miho Egoshi

Dissertations and Theses

The devastating earthquake that hit Guatemala in 1976 was used as a pretext for American born Protestant evangelicalism—mainly Pentecostalism—to gain entry in the Guatemalan society. A major consequence of the earthquake relief efforts by American evangelicals, is that their meddling also intensified the Mayan genocide during the Guatemalan Civil War (1960-96). This thesis explores the complicit relationship of religion and politics in the Guatemalan Civil War, focusing on the evangelical dictator Efraín Ríos Montt’s regime (1982-83). Firstly, it examines how Christian evangelicalism played a pivotal role for conservative Republican candidate Ronald Reagan and, later through his administration, for Ríos Montt’s …

The Spring Street Church In The Age Of Abolition, David S. Pultz

Dissertations and Theses

This study profiles the Spring Street Presbyterian Church in antebellum New York City as an integrated congregation active in the local abolitionist movement. It is framed against the rapid economic and social changes taking place within New York and the immediate neighborhood of the Eighth Ward during the early 19th century. Research focuses on religious antislavery during the Second Great Awakening and the place occupied by the Spring Street congregation as led by three of its antislavery pastors: Samuel H. Cox (1820-1825), Henry G. Ludlow, (1828-1837), and William Patton, (1837-1847). The study argues that Spring Street was a uniquely activist …

Wood Trait Preferences Of Neotropical Xylophagous Beetles (Coleoptera: Cerambycidae), Christina Torres

Dissertations and Theses

Tree life history strategies are correlated with functional plant traits, such as wood density (WD), moisture content (MC), bark thickness (BT), and nitrogen content (N); these traits affect the nutrients available to xylophagous insects. Cerambycid beetles feed on substrates that vary in these traits, but little is known about how they affect community composition. The goal of this project is to document the abundance of two cerambycid subfamilies (Cerambycinae and Lamiinae) and the WD, MC, BT, and N content in the wood they eat. In a salvage project conducted adjacent to the Panama Canal, trees were felled and exposed to …

A Role For A Predicted E. Coli Inner Membrane Lipoprotein In Cell Envelope Integrity, Charlie Chung

Dissertations and Theses

One of the distinct characteristics of Gram-negative bacteria such as Escherichia coli is the possession of a double-membraned cell envelope. The outer membrane provides an additional layer of protection against hydrophobic molecules including antibiotics, contributing to the multidrug resistance crisis. The Gram-negative membrane is composed of phospholipids, glycolipids, and proteins. A large portion of the bacterial cellular proteome is composed of membrane proteins. Despite this, the functions of several membrane proteins are as yet undefined. Therefore, defining the physiological roles of uncharacterized membrane proteins is expected to provide us with insights into the biology of the Gram-negative cell envelope and …

Crime On The High Seas: What Conditions Are Necessary To Achieve Effective Maritime Governance Regime?, Michael A. Celic

Dissertations and Theses

This thesis explores why international maritime governance regimes have inconsistent rates of success. The global community relies on the world’s oceans for food, trade, and resources. Therefore, the regulation of these oceans is necessary to provide adequate passage through its waters and the management of all the resources they supply for the mutual benefit of all. Although there are international laws such as the United Nations Convention of the Law of the Seas (UNCLOS), many of these laws fail to address current global threats and have proven inadequate in forming proactive collective responses. It is particularly problematic addressing transnational criminal …

Are Cyber Operations Having An Impact On State Electoral Processes?, Sean Joseph Mcnicholas

Dissertations and Theses

Cyber-attacks have become common occurrences which have an impact on all aspects of life ranging from business transactions to personal communications. Alarmingly, coordinated cyber-attacks are increasingly targeting politicians and their associates, political campaigns, political organizations and the broader public with political messaging. Given the novelty of these new forms of attacks, little is known of their potential impact. This thesis argues that states, state-directed actors, or non-state actors are disrupting, altering or influencing the electoral process in democratic states through coordinated cyber operations. It further argues that the purpose is to increase hyper-partisanship and erode the legitimacy of democratically-elected leaders. …

Guyana-Venezuela Border Dispute: Seeking A Peaceful Solution, Aaron Marcus Homer

Dissertations and Theses

The purpose of this thesis is to examine and evaluate the effectiveness of those dispute settlement mechanisms that are capable of resolving the Guyana-Venezuela border dispute. This thesis will analyze those legal principles and/or techniques of the International Court of Justice, mediation and the Permanent Court of Arbitration, which are indispensable for dispute resolution. I argue that a resolution is significant for the stability of the international community.

Guyana and Venezuela possess economic and political interests in the disputed Essequibo region. Venezuela’s predilection for bilateral negotiations contradicts Guyana’s request for a judicial solution. These extreme positions are not novel but …
