Electroencephalographic Asymmetry, Emotion Regulation, And Their Relationships With Depression Risk, Aliza Jacob

Dissertations, Theses, and Capstone Projects

Background: Research investigating patterns of electroencephalographic (EEG) brain asymmetry aids our understanding of neural systems involved in the processing of emotion, motivation, and psychopathology. Withdrawal-motivated negative emotions characteristic of depression are associated with relative right prefrontal cortex (PFC) activity, whereas approach- motivated positive emotions are associated with relative left PFC activity. Styles of emotion regulation (ER), or modulation of the intensity and duration of emotional responses, are also associated with presence (e.g., suppression, or maladaptive ER) versus absence (e.g., cognitive reappraisal, or adaptive ER) of depression vulnerability. Most PFC asymmetry studies of emotion, depression, and/or ER rely upon EEG recorded …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

The Role Of The Direct And Indirect Basal Ganglia Pathways In The Learning, Performance, And Goal-Directed Control Of Action Sequences, Eric Garr

Dissertations, Theses, and Capstone Projects

Animals engage in intricately woven action sequences that are constructed from trial-and-error learning, but the mechanisms by which the brain links together individual actions which are later recalled as fluid chains of behavior are not fully understood. The aim of this dissertation is to investigate the learning and goal-directed control of action sequences in rats. Experiment 1 addresses a question that comes out of a reinforcement learning model of action sequencing: how does the extent of training change how the performance of an action sequence is impacted by reward devaluation. The data show that action sequences remain goal-directed overall regardless …

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …

Impact Of Religiosity And Level Of Acculturation On Cultural Alignment: An Exploration Of Terror Management Mechanisms Among Muslim American Women, Farah T. Goheer

Dissertations, Theses, and Capstone Projects

ABSTRACT

Impact of Religiosity and Level of Acculturation on Cultural Alignment: An Exploration of Terror Management Mechanisms among Muslim American Women

by

Farah Taha Goheer, M.A.

Advisor: Joel Sneed, Ph.D.

Background: Terror management theory (TMT) is based upon the notion that human beings require ongoing psychological protection from the unyielding, existential threat of death. A large body of evidence has shown that human beings manage death-related terror by aligning with and endorsing the dominant views of their cultural worldviews. Notably, as immigrants experience a new culture, worldviews become rearticulated to incorporate elements of host and heritage cultures. However, it is …

Neural Correlates Of Automatic Emotional Processing And Emotion Regulation In Empathy And Psychopathy-Related Coldheartedness, Danielle Difilipo

Dissertations, Theses, and Capstone Projects

Psychopathy is a personality disorder that is defined, in part, by a lack of empathy. Psychopathy-related empathic deficits have been associated with atypical behavioral and neural responses to emotional facial expressions. Although the mirror neuron system (MNS) has been implicated in empathy, very few studies have examined the role of MNS functioning as it pertains to empathy impairments in psychopathy. Moreover, there is very little empirical research regarding emotion regulation in psychopathy, and specifically whether emotional responses can be intentionally upregulated. The present study sought to clarify whether the MNS is functionally intact in adults with subclinical psychopathic traits, particularly …

Perceptions Of Sexual Violence: An Investigation Of Sexual Harassment, Sexual Coercion, And Sexting, Jennifer J. Mcmahon

Dissertations, Theses, and Capstone Projects

Perpetration of sexual violence is a serious concern in the US, with research indicating that a substantial portion of the population has experienced some type of sexual victimization. There is sparse research that examines perceptions and judgments of sexually inappropriate behaviors, and existing research does not take into account the impact of individual differences and contextual factors. This study examined whether individuals recognize different forms of sexual harassment, sexual coercion, and sexting as inappropriate, and how these perceptions are affected by sex, age, and relationship status. A mixed sample of undergraduate students and adults within the community completed an online …

The Origins Of The Jones Act Of Puerto Rico, Stephanie Mercedes

Dissertations, Theses, and Capstone Projects

After the Spanish-American War that ended in 1898, Puerto Rico was given to the United States by Spain as a war booty, becoming a US colony. The first law ever created by the United States to control Puerto Rico was the Foraker Act (also known as the Organic Act of 1900). This established a civilian government in Puerto Rico. It also extended the federal government rulings to the island. After its creation, the Puerto Rican population began to wonder what their political status was since nothing was concretized until the Jones Act was signed. The Merchant Marine Act of 1920, …

Effects Of Innovations In Health Care Provision And Financing, Hoda Nouri Khajavi

Dissertations, Theses, and Capstone Projects

This dissertation consists of four chapters that study the impacts of innovations in health care provision and financing. The relentless rise in US health care costs has led the Centers for Medicare and Medicaid Services to launch various pilot programs to create financial incentives for health care providers, suppliers, and local communities to improve the efficiency of the health care system. The fist chapter of this manuscript reviews the main pilot programs implemented and/or funded by the Centers for Medicare and Medicaid Services since the 111th United States Congress passed the Patient Protection and Affordable Care Act, also known as …

Exploring The Structural Effects On The Lethal Violence At The U.S. Counties Under The Situational Action Theory: An Application Of Multivariable Spatial Regression Model, Yunho Yeom

Dissertations, Theses, and Capstone Projects

Since the stream analogy (Unnithan, Corzine, Huff-Corzine, & Whitt, 1994) and the frustration-aggression approach (Henry & Short, 1954) in lethal violence phenomenon analysis, several scholars have integrated theories from outside of their fields of study to understand lethal violence under a single theoretical framework. Some of these researchers have focused on deteriorating socioeconomic conditions and the collective attributional style when explaining the causes of lethal violence; others have failed to assume the non-independence of observation among contextual predictors. Recognizing these shortcomings, this study integrates the social components of situational action theory to examine their mediating effects on the relationship between …

Murine Genetic Variance In Sugar And Fat-Conditioned Flavor Preferences: Roles Of Dopamine, Opioid And Nmda Receptors And Nutritive Sensing, Tamar T. Kraft

Dissertations, Theses, and Capstone Projects

As obesity and diabetes have emerged as a severe public health crisis, understanding the mechanisms underlying the consumption of sugars and fats has become a topic of vigorous study. From a biological standpoint, genetic dispositions, neurochemical and hormonal influences, and predetermined orosensory and postingestive signals that modulate the hunger and satiety process may govern physiological aspects of the obesity puzzle. In addition to an innate appetite and attraction for simple carbohydrates and fats, learning plays an important role in modulating preferences for sugar- and fat-rich foods in rodents, including inbred mouse strains. Marked genetic variance has been observed among murine …

Infinity Wars: Post 9/11 Superhero Films And American Empire, Peter J. Bruno

Dissertations, Theses, and Capstone Projects

In the last two decades, superhero films have accounted for some of the most popular and financially lucrative films of all time. This thesis analyzes some of the aesthetic and ideological dimensions of various superhero films following their post 9/11 boom. Beginning with America’s response to the events of 9/11 and a subsequent retreat into a Manichean world of good versus evil, I introduce the term “empirical reality” in order to account for the ways daily American life is shielded from the worst effects of U.S. foreign policy. On screen this manifests by perpetuating the myth of the “clean war” …

The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses

Dissertations, Theses, and Capstone Projects

The three-stage model of distraction asserts that when we are presented with salient but task-irrelevant information, our sensory systems first detect the distracting stimulus by way of sensory memory buffers, which is indicated electrophysiologically by the mismatch negativity (MMN). Following detection, attentional resources are involuntarily allocated towards the processing of the distraction, as represented by the P3a. Finally, attentional resources are shifted away from the distracting stimulus and returned to the task-relevant information, as indicated by the reorienting negativity (RON). A great deal of research has focused on this last step in the model, largely centering around defining the mechanisms …

Essays On Applied Machine Learning For Implied Volatility Interpolation And Artificial Counterfactuals, Pablo A. Crespo

Dissertations, Theses, and Capstone Projects

This dissertation consists of two chapters.

Chapter 1: Volatility estimates under the risk neutral density have become a much revisited topic of interest in recent years. The density proves itself a powerful tool for sentiment analysis, since its moments provide insights about expectations in price trends. A standard procedure for its extraction utilizes artificial volatility predictions to form a dense enough grid for approximating a complete probability distribution. This paper proposes two common machine learning technique variations to produce implied volatility predictions when data is very scarce. First, a model using regularization through a variation of a generalized LASSO path …

Clientelism And Democracy In Turkey And Mexico: The Impacts On Regimes Of Political Party Exploitation Of Housing Tenure In Informal Settlements, David J. Henry

Dissertations, Theses, and Capstone Projects

Scholars have identified the abuse of state resources as one of the primary indicators of whether a country will democratize. Clientelist networks are critical to how incumbents exploit state assets to remain in power. When the informal relationships of clientelist parties undermine the formal institutions of the state, the regime is no longer democratic, even where competitive elections take place. Alternately, if a ruling party in such hybrid regimes loses its monopoly on state power, it creates an opening for other parties and social groups to push for democratization. Mexico and Turkey are critical case studies on how clientelist parties …

Internal And External Attention In Autism Spectrum Disorder, Tehila Eilam-Stock

Dissertations, Theses, and Capstone Projects

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental condition affecting individuals throughout the lifespan. Sensory hypersensitivity and superior perceptual acuity are well documented in individuals with ASD, and may indicate heightened orientation of attention to external stimuli, as attention can augment sensory perception. Recent evidence from mind-wandering research suggests that the ability to disengage attention from the external environment and direct it internally to self-generated mentation is crucial for adaptive cognition and behavior, as it allows for incorporation of past knowledge and experience in the interpretation of novel situations. We hypothesized that ASD is related to an imbalance between externally …

Unstitching The Borders: Color, Class And Consumption In Queens, New York, Cassandra R. Barnes

Dissertations, Theses, and Capstone Projects

The following thesis is a comparative multipart examination into the ways in which globalization, translocality, and gentrification influence communities and their inhabitants through the lens of fashion. Political and social forces drive processes of consumption. In the Corona and Jackson Heights sections of Queens, New York, several waves of migration and immigration have given rise to an extremely diverse yet socially complex area. Historically, four major shopping districts: Roosevelt Avenue, 74^th Street, 82^nd Street, and Junction Boulevard developed in the two towns and reflected much of the demography within. Currently these districts are physically accessible to anyone able …

Structure And Function Of Dopamine In The Inner Ear And Auditory Efferent System Of A Vocal Fish, Jonathan T. Perelmuter

Dissertations, Theses, and Capstone Projects

The neuromodulator dopamine is considered essential for coordinating the internal motivational state of an organism with appropriate behavioral responses to stimuli in the external environment. This could be accomplished by modifying the function of neural circuits involved in sensory processing such that they are “tuned in” and optimally sensitive to important stimuli during critical time windows. While dopamine modulation of auditory processing has been studied in the central nervous system, neuromodulation can also occur outside the brain, in the inner ear. The majority of investigations of dopamine in the ear are conducted using rodents and focus on its role in …

‘Its Something You Do Bro’: Language And Identity On A Male Erotic Hypnosis Messageboard, Eric Chambers

Dissertations, Theses, and Capstone Projects

Drawing on a seven-year corpus of data (total words N = 86,881) on a publicly-accessible messageboard on which self-identified gay men discuss their experiences undergoing erotic hypnosis, this study applies Critical Discourse Analysis methods to understand how posters understand their sexual identities and those of others. This study identifies the emergence of two main identity-types at-play on OnYourKnees: the jock and the coach. Jocks are generally characterized by a focus on sports and body-consciousness, a disinterest or inability to engage in scholarly/academic pursuits, and a desire to be submissive to others to achieve sexual pleasure. Coaches, on the other hand, …

Emperor Of Work: Chinese Restaurants, Worker Subjectivities, And The New Regime Of Flexible Labor, Tommy Wu

Dissertations, Theses, and Capstone Projects

This study is an ethnographic exploration of Chinese immigrants who work in Chinese and Asian fusion restaurants across the country. Based on sixteen months of fieldwork using participant observations, interviews, and social media analysis, my research follows workers as they negotiate and contest the changing work arrangement of an industry that is largely invisible to the general public and to the state. Specifically, despite the industry’s astronomical growth in the last few decades, with estimates nearing 50,000 in the country, little is known about the social and economic organization that fuels the expansion. Further, it is also puzzling why the …

The Evolution Of Mara Salvatrucha 13 And Barrio 18: Violence, Extortion, And Drug Trafficking In The Northern Triangle Of Central America, Pamela Ruiz

Dissertations, Theses, and Capstone Projects

The Mara Salvatrucha 13 (mara) and Barrio 18 (pandilla) gangs have become a major concern for the governments of the Northern Triangle of Central America (Guatemala, El Salvador, and Honduras) and the United States. In recent years, government officials have attributed violence and the exodus of Central Americans to the developing capacities of gangs. The Mara Salvatrucha 13(MS-13) and Barrio 18 have been identified to strategically implement violence and extortion rackets which have led to transformations in their organizational structures and increased participation in drug trafficking. Furthermore, officials insinuate that gangs have developed capacities to confront security forces that enter …

Prepositional Phrase Attachment Ambiguities In Declarative And Interrogative Contexts: Oral Reading Data, Tyler J. Peckenpaugh

Dissertations, Theses, and Capstone Projects

Certain English sentences containing multiple prepositional phrases (e.g., She had planned to cram the paperwork in the drawer into her briefcase) have been reported to be prone to mis-parsing of a kind that is standardly called a “garden path.” The mis-parse stems from the temporary ambiguity of the first prepositional phrase (PP1: in the drawer), which tends to be interpreted initially as the goal argument of the verb cram. If the sentence ended there, that would be correct. But that analysis is overridden when the second prepositional phrase (PP2: into her briefcase) is encountered, since the …

Do It Like A Syntactician: Using Binary Gramaticality Judgements To Train Sentence Encoders And Assess Their Sensitivity To Syntactic Structure, Pablo Gonzalez Martinez

Dissertations, Theses, and Capstone Projects

The binary nature of grammaticality judgments and their use to access the structure of syntax are a staple of modern linguistics. However, computational models of natural language rarely make use of grammaticality in their training or application. Furthermore, developments in modern neural NLP have produced a myriad of methods that push the baselines in many complex tasks, but those methods are typically not evaluated from a linguistic perspective. In this dissertation I use grammaticality judgements with artificially generated ungrammatical sentences to assess the performance of several neural encoders and propose them as a suitable training target to make models learn …

Caring Without Sharing: Philanthropy's Creation And Destruction Of The Common World, Amy B. Schiller

Dissertations, Theses, and Capstone Projects

This dissertation explores multiple ways philanthropy builds and undermines the common world. Political science treatments of philanthropy have focused mainly on its role in the development of civil society, with a recent turn towards critiques of philanthropy as an instrument of elite power and tension between private wealth and democratic governance. In this dissertation, I examine how philanthropy can foster enduring spaces of human flourishing, or reduce beneficiaries to objects of pity, surveillance and domination. I trace philanthropy's evolution from ancient to contemporary contexts and propose a framework for philanthropy to, under certain conditions, build and care for the common …

Patient And Provider Perspectives On Sexual History Taking During Gynecological Care: A Pilot Study In An Academic Family Medical Setting In New York City, Ashley M. Chastain

Dissertations and Theses

Background: In the United States (US), women face a number of serious issues concerning sexual health. Current surveillance data indicates that overall rates of bacterial sexually transmitted infections (STIs) are increasing rapidly. While rates of new diagnoses have decreased, the risks of acquiring HIV are still relatively high for some females, specifically Black/African-American women. In New York City (NYC), where this dissertation research was conducted, similar HIV/STI rates exist among females of reproductive age (aged 15-44). Among women in the US, there are also high estimated rates of other sexual health problems, such as sexual anxiety, sexual dysfunction, and intimate …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

Same-Sex Union Formation And Dissolution In The United States And Europe, Eric Ketcham

Dissertations, Theses, and Capstone Projects

Despite recent improvements in the availability of data on same-sex union formation and dissolution, the field remains understudied. Recent findings on the stability of same-sex unions in the United States and in Europe are inconsistent both within and between countries. Using three data sets – How Couples Meet and Stay Together, the Generations and Gender Survey, and the Longitudinal Internet Studies for the Social sciences surveys – event-history analyses are conducted to examine the stability of same-sex unions relative to male-female unions in the United States and continental Europe. The availability of partners for LGBT-identified males and females in eighteen …

Essays In Empirical Economics, Agustin Indaco

Dissertations, Theses, and Capstone Projects

This dissertation consists of two chapters that utilize distinct econometric methods and novel datasets.

In the first chapter, “From Twitter to GDP: Estimating Economic Activity From Social Media”, I collect all geo-located image tweets shared on Twitter in 2012-2013 to study whether the volume of tweets is a valid proxy for estimating current GDP in USD at the country level. My preferred model explains 94 percent of the cross-country variation and the residuals from the model are negatively correlated to a data quality index, indicating that my estimates of GDP are more accurate for countries with more reliable GDP data. …

Waiting: History, Fear, And Healing In Ballynafeigh / The Upper Ormeau Road Of Belfast, Northern Ireland, Molly J. Hurley-Depret

Dissertations, Theses, and Capstone Projects

Based on fourteen months of ethnographic fieldwork in one neighborhood of Belfast called Ballynafeigh / the upper Ormeau Road in 2006–2007, I argue we need to pay closer attention to the “inconspicuous transformations” that may have been occurring in parallel to the official peace process. Walter Benjamin notes that “refined and spiritual things” do “make their presence felt in the class struggle. They manifest themselves in this struggle as courage, humour, cunning, and fortitude.” Benjamin states that “the past strives to turn toward that sun which is rising in the sky of history. A historical materialist must be aware of …

The Impact Of Racial Microaggressions And Major Discriminatory Events On Mental Health, Florence Lui

Dissertations, Theses, and Capstone Projects

The current study, a secondary data analysis, sought to determine the number and nature of latent groups for experiences of spectrum racial discrimination (i.e., both major and microaggressive racial discrimination) in a sample of emerging adults from a people of color (POC)-majority public university setting in the United States, and to understand the role of socio-demographic variables in defining each group. In addition, the study aimed to ascertain the extent to which endorsing spectrum racial discrimination experiences predicted anxiety and/or depression above the effects of general, non-race-related stress. Finally, the analyses gauged the mediating and/or moderating role of coping in …
