Testing Visual Ecology Hypotheses In Avian Brood Parasite-Host Systems: The Role Of Uv-Light Perception And Egg-Nest Contrast In Foreign Egg Rejection, Zachary Aidala

Dissertations, Theses, and Capstone Projects

Color signals are highly important features of animal communication systems, particularly among birds, which possess exquisitely complex visual perception systems. Birds possess tetrachromatic vision, and some species are sensitive to ultraviolet (UV) wavelengths. Because human and avian visual systems dramatically differ (i.e. humans are not sensitive to UV wavelengths), biologically relevant sensory models are necessary to accurately assess the function of avian color signals. In this dissertation, I primarily use brood parasite-host interactions as a model for studying the behavioral function of avian-perceivable visual stimuli. In Chapter 1, I review the importance of employing biologically relevant sensory-perceptual visual models when …

Electrophysiological Markers Of Short-Term Visual Adaptation: An Examination Across The Schizophrenia Spectrum, Gizely N. Andrade

Dissertations, Theses, and Capstone Projects

The experiments comprising this dissertation sought to contribute to the understanding of basic sensory processing in schizophrenia-spectrum disorders and risk-liability. We leveraged the sensitivity of visual processing deficits along with widely reported sensory-gating deficits (in other modalities) to develop a new paradigm assaying short-term visual adaptation to repetitive stimuli. In the first experiment, adaptation properties of the visual system were characterized in neurotypical adults using a classic "paired adaptation paradigm" and a more taxing "block adaptation paradigm," using high-density EEG. In the second experiment, we deployed our new visual adaptation assay in a clinical population. We replicated classic early VEP …

Narratives Of Interiority: Black Lives In The U.S. Capital, 1919 - 1942, Paula C. Austin

Dissertations, Theses, and Capstone Projects

This dissertation constructs an urban, social and intellectual history of poor and working class African Americans in the interwar period in Washington, D.C. Although the advent of social history shifted scholarly emphasis onto the "ninety-nine percent," many scholars have framed black history as the story of either the educated, uplifted and accomplished elite, or of a culturally depressed monolithic urban mass in need of the alleviation of structural obstacles to advancement. A history of the poor and working class as individuals with both ideas and subjectivity has often been difficult simply because there are limited archival sources.

Control Of Cell Cycle Progression By Mtor, Amrita Chatterjee

Dissertations, Theses, and Capstone Projects

Over the past few years it has become apparent that cancer cells require the activation of a set of intra-cellular signals that promote cell cycle progression and survival. One of the most common survival signals activated in human cancers is mediated by mTOR -the mammalian target of rapamycin. mTOR is a critical nutrient and energy sensor in cells that lets the cell know that there is sufficient material available for a cell to double its mass and divide. mTOR causes the phosphorylation of downstream targets ribosomal subunit S6 kinase and eukaryotic initiation factor 4E (eIF4E) binding protein-1 (4E-BP1), which promotes …

Traumatic Familiarity: Fictions And Theories Of Community In The Eighteenth Century, Andrew Scott Dicus

Dissertations, Theses, and Capstone Projects

This dissertation addresses a crisis of modern collective identity by employing a dialectic of philosophical and literary "realisms." While both philosophical and novelistic discourses are premised on twin gestures (aspiration for correspondence between representation and reality), they arrive at radically different claims about how rational, self-governing individuals constitute - and are constituted by - "legitimate" social bodies. By foregrounding the internal complexity and empirical immersion of "real" individuals negotiating "realistic" social encounters, eighteenth-century novelists engage in a sustained critique of emerging concepts of "legitimate" community. Penetrating even the most basic foundations of social knowledge, such as the capacity to distinguish …

A Review Of Teacher Preparation In New York City: Through An Analysis Of The Teacher Academy, Naomi Uchechuwku Nwosu

Dissertations, Theses, and Capstone Projects

The purpose of this study has been to explore alternative and traditional teacher preparation programs through an analysis of the City University of New York's Teacher Academy program. This study explored the following three aspects of the Teacher Academy: (1) the planning phase- identifying the goal of the Teacher Academy and how the program was envisioned to change teacher preparation within the City University of New York, (2) the implementation phase- identifying the components of the Teacher Academy that were aligned with either or both alternative and traditional teacher preparation programs, and (3) the discontinuation phase- the decision by program …

Women Of Faith: Adaptation Of African American Women Breast Cancer Survivors, Pearline Lincoln Okumakpeyi

Dissertations, Theses, and Capstone Projects

The purpose of this study was to gain an understanding of the adaptation experience of African American women breast cancer survivors. The African American women's perception of the influence of faith on the breast cancer survivorship experience was explored.

This study utilized the directed qualitative content analysis method, which extracted themes and patterns that emerged in a narrative content. The 15 study participants were self-identified African American breast cancer survivors. The study was conducted using semi-structured interview questions that were derived from the modes of the Roy Adaptation Model (RAM). The discussion was framed within the context of the themes …

The Journal Of Mother Studies: A Peer Reviewed, International, Interdisciplinary, Open-Acess, Digital Humanities Hybrid Project, Martha Joy Rose

Dissertations, Theses, and Capstone Projects

Academic Journals are an established forum for educators and researchers to disseminate information within their field. Journals act as mediators of knowledge, advancing the canons within specific areas of study. There are currently two journals that focus on motherhood from an interdisciplinary perspective and one that focuses on fathers. However, none of these determine a specific foundational definition of what the field is, what it hopes to study, and how it will advance itself. Rather, these journals are general collections of a great number of things that touch on varying subjects regarding motherhood and fatherhood. This thesis argues for the …

Generalized Event Representation In Pre-School Children With Mild- To High-Functioning Autism Spectrum Disorder (Asd) And Children With Cognitive And Linguistic Delays (Cld), Tashana S. Samuel

Dissertations, Theses, and Capstone Projects

Children with autism spectrum disorder (ASD) frequently establish rigid routines and have difficulties flexibly applying what they have learned. Three experiments were conducted to examine generalized event representation in 34 pre-school children. In Experiment 1, children diagnosed with varying kinds of cognitive and language delays (CLD: n = 14) were tested with the generalized imitation paradigm, a reliable measure of representational capacity. Two sets of perceptually dissimilar objects with similar functions were used to perform the same task: one set consisted of modeling props and the other set was the generalization props. At the generalization assessment, children observed actions modeled …

Successful Implementation Of Solution-Based Casework; A Child Welfare Casework Practice Model?, Naomi Weisel Schear

Dissertations, Theses, and Capstone Projects

Across the country, child welfare agencies have started to implement casework practice models in an effort to improve the safety, permanency and well-being of vulnerable children and families. In their effort to do so, child welfare systems have faced complex contextual challenges to implementation. To date, however, there has been limited empirical research describing successful implementation of these practices. Moreover, little systematic feedback exists concerning service providers' perspectives of various aspects of the implementation process.

The purpose of this qualitative research study was to explore child welfare supervisors' and case workers' responses to various methods of implementation of Solution-Based Casework …

Using A Multisystemic Approach To Examine Youth Risky Sexual Attitudes And Behavior, Chamane Melissa Simpson

Dissertations, Theses, and Capstone Projects

The current investigation examined the relationship between the risky sexual attitudes/behavior of 18 to 24 year old college students (N = 250) and variables from the self-, family, and peer systems. The variables that were used to predict participants' risky sexual attitudes and behavior included gender, three self-esteem constructs (i.e., global self-esteem level and parental/peer approval contingent self-esteem), and participants' perceptions of their parent/caregiver and peer's attitudes toward risky sex. Lastly, social desirability was used as a control variable.

Taken together, the goals of the study were to: (a) determine whether global self-esteem level or parental/peer approval contingent self-esteem would …

What Condoms Can't Cover: Do Structural Factors Predispose Black, African American, And Latina/O Adults In Harlem And The South Bronx To Engaging In Hiv Sex Risk Behaviors?, Fabienne Snowden

Dissertations, Theses, and Capstone Projects

More than thirty years into the HIV/AIDS epidemic, Black, African American, and Latina/o communities continue to demonstrate the highest rates of HIV/AIDS in the US, accounting for 64% of all new infections and 58% of all AIDS diagnoses in 2009. Despite the longevity of this public health crisis, individually-based behavioral change approaches to HIV/AIDS prevention continue to be the most widely used and funded methods of combating HIV risk in Black, African American and Latina/o communities. These methods have been proven to lower the risk of HIV transmission, but HIV incidence in the US remains high at approximately 50, 000 …

Nuclear Pore Protein Nup211 Is Essential For Cell Cycle Progression And Cell Shape Maintenance In Fission Yeast, Ayisha R. Sookdeo

Dissertations, Theses, and Capstone Projects

The nuclear pore complexes (NPCs) are large multi-protein channels that traverse the nuclear envelope and mediate nucleo-cytoplasmic transport. Proteomic studies have revealed that NPCs are composed of about thirty different proteins called nucleoporins. I explored a particular nucleoporin, Nup211, in fission yeast. nup211 is an essential gene; its deletion is lethal and causes morphological defects. In this study, I characterized the cell morphological defects caused by the down-regulation of Nup211 and found that restoring the N-terminal domain of Nup211 was sufficient to rescue the lethal phenotype and partially suppress the morphological defects. Additionally, I investigated the role Nup211 plays in …

Phylogeography Of Southeast Asian Flying Foxes (Chiroptera: Pteropodidae: Pteropus), Susan Man Shu Tsang

Dissertations, Theses, and Capstone Projects

Flying foxes (Pteropus) are a genus of Old World fruit bats that are important seed dispersers and pollinators for plants native to the 200,000+ islands in Southeast Asia, yet they are some of the most poorly known bats in the world. They comprise some of the largest known bat species, and are morphologically relatively conserved on the genus level. Pteropus is the most species-rich genus within Pteropodidae, though the origin for this diversity remains incompletely understood. In Chapter 1, I discuss the importance of Pteropus to the ecosystem and as reservoir hosts. In Chapter 2, a molecular phylogeny is presented …

Touching Time: Forms Of Romantic Temporality, Leila Walker

Dissertations, Theses, and Capstone Projects

The sense of touch has largely been neglected in the study of Romantic literature. While recent histories of the senses hold that sight and touch became disarticulated toward the end of the eighteenth century and the beginning of the nineteenth, these studies tend to emphasize the elevation of sight as a more advanced mode of perception, suitable for observing experiments or appreciating art, over the more base sense of touch. Questions of tactility tend to be absorbed into histories of materiality or the body, and this terminological slippage becomes particularly apparent as these histories enter the Romantic period. However, when …

Object Categorization In Children With Autism Spectrum Disorder (Asd), Jaime Vitrano

Dissertations, Theses, and Capstone Projects

The purpose of this study was to investigate hierarchical object categorization in children with autism spectrum disorder (ASD), examining three levels of category inclusiveness (superordinate, basic, subordinate) across three tasks (sequential touching task, generalized imitation task, sorting task) in three domains (animals, tools, kitchen utensils) in the same group of children with ASD. Previous research on the categorization abilities of children with ASD has shown mixed results. This study was designed to clarify past discrepancies in the literature.

Ten children with ASD participated in this study (mean CA = 4 years, 10 months; range 3 to 6 years; mean VMA …

Triple Stigma In Forensic Psychiatric Patients: Mental Illness, Race, And Criminality, Michelle Leigh West

Dissertations, Theses, and Capstone Projects

Stigma involves negative beliefs and devaluations of people in socially identified groups (e.g. race, mental illness). Although people have many reactions to social stigma, some labeled people internalize these attitudes. Research has increasingly explored mental illness self-stigma, when people with mental illness begin to believe that society's negative beliefs are true of them (e.g., that they are hopeless due to mental illness). Self-stigma predicts poorer functional and treatment outcomes. Stigma research has typically investigated stigmatized labels individually. Forensic psychiatric patients, people with mental illness with history of criminal conviction, by definition experience multiple stigmas, yet no research has explored how …

A Gender Approach To Vulnerability And Natural Disasters, Ema Izquierdo

Dissertations, Theses, and Capstone Projects

A natural disaster is a major adverse event resulting from natural processes of the earth that overwhelm local response and affect the social and economic development of the affected region. Natural disasters have been seen as situations that create challenges and difficulties mainly of a humanitarian nature. Still, progressively, it has come to be recognized that a gendered approach to humanitarian response is essential for vulnerable populations such as girls and women. Even though information about particular cases is scarce, evidence indicates that women are more likely to die after a natural disaster not because of biological reasons but because …

Bad Apple: Complexities Of New York City Food Aid Programs, Rose Meagan Jimenez

Dissertations, Theses, and Capstone Projects

The only universal thing about food is that everyone needs to eat. In the United States, there are more instances of food insecurity than impoverishment. Governmental and local food aid programs are complex but are essentially motivated by socioeconomic issues. Food aid programs, from community gardening to Food Stamps, initially stem from a depression-era need to stimulate the economy. However, as socioeconomic issues change, food aid programs also evolve to meet those needs. By excavating different pieces of literature that discuss issues in food aid, the forms of structural violence that cause hunger come to life. This piece discusses community …

Mental Discipline And Musical Meaning, Alice Harriet Jones

Dissertations, Theses, and Capstone Projects

Musical meaning, or what a musical experience communicates to a listener, is predicated on a shared habitus of listening between the musical creator (i.e., composer, performer, or improviser) and the listener. The meaning a listener takes away from a musical experience is partly dependent on the vessel transmitting it (i.e., who is performing, the quality of performance, or the visual aspects of performance), and a musical creator's actions are the result of his or her training, past experiences, enculturation, attentional focus, and bodily control in the heightened mental state in which creativity occurs. Even in traditions that consider the musician …

Black Like Me? A Narrative Study Of Non-Anglophone Black U.S. Immigrant Selves In The Making, Yvanne Joseph

Dissertations, Theses, and Capstone Projects

The passage of the 1965 Immigration and Nationality Act abolished discriminatory national origin quotas that favored European immigrants. The U.S. has since experienced steady flows of immigrants of color. These diverse groups have brought their racial, social, cultural and historical experiences, which adds greater complexity to the existing Black/White and ingroup/outgroup models that shape group relations, and psychological theorizing about identity. This dissertation focuses specifically on the smaller, less visible, yet growing segments of these immigrant populations. It presents a study of the lives of ten individual immigrants of African descent originating from a non-Anglophone country within Africa, Latin America …

"Young Men Of The Stones": Gendering The First Palestinian Intifada, Karen Lauria

Dissertations, Theses, and Capstone Projects

The First Palestinian Intifada (1987 - 1993) began on December 9, 1987 with riots protesting the killing of a young Palestinian man by the Israeli Defense Forces. The riots quickly grew into a much larger grassroots uprising -- Intifada -- against Israeli occupation. In the following weeks and months, the Occupied Territories were engulfed in waves of protests, demonstrations, boycotts, and other acts of civil disobedience, which continued until 1993. Although Intifada protestors represented a cross-section of Palestinian society, encompassing both old and young, male and female, a single, particular masculine trope soon came to dominate-that of young male activists …

Exploring Non-Equilibrium Dynamics In Time Dependent Density Functional Theory, Kai Luo

Dissertations, Theses, and Capstone Projects

Time-dependent density functional theory (TDDFT) is a method of choice for calculations of excitation spectra and response properties in materials science and quantum chemistry. The many-body problem is mapped into a set of one-body Schrödinger equations, called the Kohn-Sham (KS) equations. In principle, the one-body potential can be chosen such that the density of the interacting system is exactly reproduced by the KS system. However, one component of the one-body potential has to be approximated and is typically "adiabatic". Though in linear response regime adiabatic approximations give quite good spectra, it is important to explore their performances in non-equilibrium dynamics. …

Proton Pumping In Cytochrome C Oxidase, Jianxun Lu

Dissertations, Theses, and Capstone Projects

Cytochrome c oxidase (CcO) is a large trans-membrane protein, which is the final enzyme in the respiratory electron transport chain in mitochondria or aerobic bacteria. It implements proton pumping through the mitochondrial membrane against the electrochemical gradient, by utilizing the chemical energy released by reducing O₂ to water. The active site of the chemical reaction is called the Binuclear Center (BNC) that is made up of heme a₃, Cu_B, a Tyrosine residue and their ligands. The protein is reduced four times by electron from cytochromes c to reduce O₂ and to generate four different …

Middle School Girls In Postfeminist Times, Susan Mccullough

Dissertations, Theses, and Capstone Projects

This dissertation, based on an ethnographic case study conducted in the 2013-14 school year, examines early adolescent girls and their teachers and the way in which they experience gender and gender relations in the public middle school context in New York City. Current research into schools in the United States tends to focus on the experience of those students who are in crisis. For the most part, girls are not considered to be a demographic in crisis in public schools in the United States today. Because research on gender and schooling that highlights the success of girls is based on …

Development And Validation Of A Bangladeshi Pediatric Silhouette Scale (Bpss), Ana Mola

Dissertations, Theses, and Capstone Projects

There is no culturally congruent children's silhouette scale to understand how Bangladeshi mothers perceive their children's body sizes and weight categories. The purpose of this study was to develop and validate an ethnic congruent Bangladeshi Pediatric Silhouette Scale (BPSS) and a facial feature scale to assess the mothers' perceptions of their children's body sizes, weight categories and facial features. The study methodology was a quantitative, descriptive design with scale content validation. The sample was comprised of 29 Bangladeshis mothers ages 25-40 and their four-five year old children living in London, England and New York City. The Mola Facetool analyses revealed …

Growing Up Online: Identity, Development And Agency In Networked Girlhoods, Claire M. Fontaine

Dissertations, Theses, and Capstone Projects

Young women's digital media practices unfold within a postfeminist media landscape dominated by rapidly circulating visual representations that often promote superficial readings of human value. Meanwhile the dominant framing within educational policy and practice of digital media literacy insufficiently captures young people's motivations for engaging in multimedia production, online gaming and blogging. In addition to using digital media for social purposes, and to navigate dimensions of social difference like race, class and gender, working class young women of color also use digital media to develop internal awareness of their selves. The processes of documenting the self, reflecting on the documented …

Microfossils As Proxies For Holocene Climate In Semi-Enclosed Basins: The Hudson River Estuary, New York, Usa And The Marmara Sea, Turkey, Damayanti Gurung

Dissertations, Theses, and Capstone Projects

The transition from the late Pleistocene glacial to the warmer Holocene interglacial occurred within a series of climatic oscillations. The Holocene, a relatively warm and stable period, was also marked by smaller climatic variability of millennial- to-centennial-scale oscillations. Furthermore, during this period global sea level was much lower than at present. My present study will analyze micro-fossils as proxies for their response to these climatic fluctuations, as well as marine influences during the late Pleistocene to Holocene periods. Sediments from marginal basin environments have been selected for the study due to their connection to the open sea and terrestrial environments, …

The Effects Of Cooling During Gait On Gait Endurance In Persons With Multiple Sclerosis Using The Six Minute Walk Test, Meghan Higgins, Esther Sosowsky, Elisheva Zinberg

Dissertations, Theses, and Capstone Projects

Background: Persons with MS (pwMS) are limited in their mobility due to thermosensitivity. Exercising at a sufficient volume and intensity to increase mobility can result in increased core temperatures and resultant worsening of symptoms. The use of cooling garments to lower core temperature has been found to be a successful means of allowing pwMS to exercise for longer periods. Previous studies have relied on precooling for an extended period of time prior to activity, to achieve improved exercise performance. Cooling during the performance itself, or pericooling, may allow for similar performance gains to be realized without spending the time needed …

Leveraging Capacity: Technical Solutions To Hunger In The Era Of Neoliberalism, Elizabeth Perry Bullock

Dissertations, Theses, and Capstone Projects

Leveraging Capacity: Technical Solutions to Hunger in the Era of Neoliberalism takes the Global Seed Vault and the value of "global crop diversity" as a point of departure for raising questions about the influence of digital technology on the seed and about the solution to hunger known as "global food security." Discussions about food security among food studies scholars highlight either the failures of global public health advocates to regulate the food and beverage industry or they view food security, like earlier campaigns against global hunger, as an instrument for U.S. foreign policy. On either side of this debate, the …
