The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies

Dissertations, Theses, and Capstone Projects

Cannabis use among patients with schizophrenia-spectrum disorders (SSD) is at significantly greater levels than in healthy populations but the impact of cannabis on neural mechanisms of clinical improvement is poorly understood. Cognitive functioning and neural connectivity are disrupted as a result of both SSD and cannabis use, and research indicates that neuropsychological capacity and connectivity of the striatum, a region involved in salience and reward processing, may be integral to effective antipsychotic drug (AP) treatment response. Despite this overlap, no previous research has investigated the effect of cannabis on the brain functions implicated in AP treatment response. The present study …

Efficacy, Acceptance, And Feasibility Of Virtual Reality For Chronic Pain Relief In Older Adult Veterans Residing In Long Term Care, Valicia Philibert

Dissertations, Theses, and Capstone Projects

Older adults residing in Long-Term Care (LTC) have a high prevalence of chronic pain. Pain management strategies have primarily focused on pharmacological approaches, but with physiological changes associated with aging, this population is at an increased risk for adverse effects from prescribed medications. More research is needed on innovative non-pharmacological interventions in the LTC setting. This study examined the feasibility, acceptance, and preliminary efficacy of Virtual Reality (VR) for chronic pain among older adult veterans in LTC. In this quasi-experimental, 12 older adult participants living with chronic pain in a long-term care facility received two sessions of VR. Pain intensity …

Let ‘Em Talk: An Exploration Of And Challenge To The White Supremacy And Colonization Of Black And Brown Girls In United States Public Schools, Keara Small

Dissertations, Theses, and Capstone Projects

The United States Department of Education’s mission statement is described as evolving to “Promote student achievement and preparation for global competitiveness by fostering educational excellence and ensuring equal access.” A key piece of this statement is educational excellence and equality. The pathway to educational excellence and preparation is founded on public school students growing aware of their culture, identity, and history. My objective in this research is to discuss educators’ perceptions and misconceptions about Black and Brown children — especially Brown and Black girls—who attend public schools across the United States. Present-day research regarding school discipline policies and the “policing” …

Clustered Protocadherins Ubiquitination And Phosphorylation Regulates Surface Expression, Albert Ptashnik

Dissertations, Theses, and Capstone Projects

Clustered protocadherins (Pcdhs) are a family of 60 adhesion-like molecules forming a neural barcode. In vertebrate neurons, 60 Pcdhs are coded by a large gene cluster. Numerous axons in the cluster are coding for the different extracellular, transmembrane, variable portion of the cytoplasmic and constant cytoplasmic domains where their expression is controlled epigenetically. These proteins mediate interactions between axons, dendrites, and glial cells during neural development. Yet, Pcdhs are not strictly adhesion molecules. In the amacrine cells of the retina, Pcdhs promote avoidance of the same cell dendrites, where in the cortex Pcdhs promote interactions between dendrites and astrocytes. In …

Towards Explaining Variation In Entrainment, Andreas Weise

Dissertations, Theses, and Capstone Projects

Entrainment refers to the tendency of human speakers to adapt to their interlocutors to become more similar to them. This affects various dimensions and occurs in many contexts, allowing for rich applications in human-computer interaction. However, it is not exhibited by every speaker in every conversation but varies widely across features, speakers, and contexts, hindering broad application. This variation, whose guiding principles are poorly understood even after decades of entrainment research, is the subject of this thesis. We begin with a comprehensive literature review that serves as the foundation of our own work and provides a reference to guide future …

Free Improvisation Pedagogy: An Arts Based Research Approach To Promoting Student Agency And Embracing Difference, Nicholas Catino

Dissertations, Theses, and Capstone Projects

Free Improvisation Pedagogy explores the changing perspectives of students as they co-create musical improvisations. Free improvisation is understood as a site for transformative pedagogy, with the possibility for people to break free of structures, think and perform independently, broaden their perspective of proper tonality, engage in musical democracy and equality of voice, and participate in music making that is active, participatory, and continually evolving.

Working with a small group of High School students in suburban New York, this research explores these topics and documents, through audio, video, visual art, and conversation, how students experience this type of music making and …

Dietary Regulation Of Silent Synapses In The Dorsolateral Striatum, Allison M. Meyers

Dissertations, Theses, and Capstone Projects

Obesity and drugs of abuse share overlapping neural circuits and behaviors. Cravings for drugs of abuse increase during abstinence, a phenomenon known as incubation. In obesity, increased craving is observed in individuals during dieting. Diets often fail, with return to- or increase above- original weight. The extent to which this reflects an incubation phenomenon has not been carefully examined. One mechanism underlying incubation is the reemergence of a developmental mechanism called silent synapses. Silent synapses are 'temporary' synapses that are important for remodeling brain circuits. They are prevalent during early development but largely disappear by adulthood. Drugs of abuse increase …

Virtual Reality Supplement To The Peers Social Skills Intervention For Adolescents With Asd, Kevin Ambrose

Dissertations, Theses, and Capstone Projects

The purpose of this study was to replicate findings of the Program for the Education and Enrichment of Relation Skills (PEERS) parent-assisted social skills training program for a diverse group of adolescents with historical autism spectrum disorder (ASD) diagnoses in an urban locality. Additionally, this study sought to pilot a 3D multi-user virtual environment for adolescent participants and an online learning community for parent coaches; both hypothesized to reinforce the social skills curriculum. A randomized controlled trial of PEERS was completed with 12 adolescents diagnosed with ASD with some participation from their caregivers. Results show that participants who received the …

"Secession's Moving Foundation": Fugitive Slave Rendition And The Politics Of American Slavery, Evan Turiano

Dissertations, Theses, and Capstone Projects

This dissertation examines the political conflict over fugitive slave rendition from the era of the American Revolution through the passage of the 1850 Fugitive Slave Law. It pays particular attention to the struggle over the legal rights due to African Americans accused of being fugitive slaves. Slaveholders claimed an absolute property right over accused fugitive slaves and argued that any recognition of legal remedies for accused runaways threatened that right. Free African Americans and their allies in the abolitionist movement asserted that Black people accused of having escaped slavery were due a legal process. This was a vital protection against …

Past Actions And Expertise: How States Infer Enemy Intentions, Yu Aoki

Dissertations, Theses, and Capstone Projects

Whether and how a state’s past military (in)actions affect perceptions of its resolve and intentions has been disputed. This dissertation argues that non-experts and experts in governments use enemy past actions differently to infer enemy resolve and intentions. Experts are those who have rich knowledge about enemies (e.g., country specialists and intelligence analysts), whereas non-experts are those who do not (e.g., top policymakers). The theory argues that non-experts are influenced by what psychologists call the “negativity bias,” which compels them to pay more attention to negative information than positive information concerning enemies. On the other hand, building on experimental findings …

Investigating Young Adult Cancer Survivors' Perspectives On Their Future And Interpersonal Relationships, Zeba N. Ahmad

Dissertations, Theses, and Capstone Projects

For many young adults (YA, aged 18-39) who have recently survived cancer, planning and working towards goals for the future is a fraught process. Prior research consistently identifies the challenges of survivorship, including: rebuilding personal identity, accepting the impact of cancer-related interruptions on personal goals, navigating new roles in significant close relationships, and initiating new relationships as a survivor. However, there is limited research describing the mechanisms underlying these persistent challenges, which poses difficulties when tailoring evidence-based psychological intervention. The present study consolidates both established and newly hypothesized survivorship challenges into a novel conceptual model, hypothesizing that they are interrelated, …

A Pilot Feasibility Trial Of Mindfulness And Modification Therapy For Males Who Use Aggression, Jenny Mitchell

Dissertations, Theses, and Capstone Projects

Physical aggression incurs substantial harm to victims and witnesses, particularly when it occurs within close relationships such as family, friendships, or intimate partnerships. Men who use aggression against partners and other adults frequently experience high levels of psychopathology, including depression, posttraumatic stress symptoms, anxious/insecure attachment, paranoia, bipolar disorder, intermittent explosive disorder, personality disorders, and substance abuse, which contribute to use of aggressive behaviors. However, existing treatments for aggression often do not address these symptoms. It is important that treatments for aggression are grounded in theoretical literature and backed by empirical support in order to increase treatment engagement and effectiveness. Treatments …

Mitigating The Harm Of Public Mass Shooting Incidents Through Situational Crime Prevention, Emily Greene-Colozzi

Dissertations, Theses, and Capstone Projects

This dissertation used environmental theoretical frameworks to understand how public mass shooting incidents are impacted by aspects of the crime situation and opportunity. Predatory, public shootings perpetrated by individuals with evidence of mass intent were examined in the United States between 1966 and 2019. This project progressed in several distinct steps with discrete aims: (1) establish an open source database of public mass shooting incidents meeting definitional criteria; (2) perform statistical analysis, including latent class analysis, regression modeling, and structural equational modeling to assess research questions; and (3) perform comparative case studies and crime script analysis to assess situational crime …

Fathers Are Fathers Are Fathers: How Sociocultural Context And Sexual Orientation Influence The Gendering Of Children, Sarah M. Frantz

Dissertations, Theses, and Capstone Projects

Though the body of literature on gay father-headed families indicates there is no significant differences on measures of gender normativity and well-being between children raised with two dads and their peers raised by heterosexual parents, there is a proliferation of anti-LGBTQ+ policies throughout the United States aimed at limiting this community’s rights and silencing their lived experiences. Given that sociocultural and political environments vary greatly state-to-state, it is important to see how the specific context in which fathers live may impact their differential parenting of sons and daughters, their gender beliefs, and the way they feel they would navigate gender …

The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig

Dissertations, Theses, and Capstone Projects

Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …

Carceral Calisthenics: Physical Culture In The Hood, Albert L. De La Tierra

Dissertations, Theses, and Capstone Projects

How do racialized men who reside in structurally marginalized locales that are putatively regarded as “the hood” navigate and manage their social conditions? This dissertation sheds light on this question by treating “street workout,” a physical culture centered around calisthenics exercises performed in public space, as an empirical site for generating a situated understanding of how some Black men assert themselves in social space at the same time that they are asserted upon by social forces. Taking an ethico-onto-epistem-ological stance that refuses the colonial gaze (a ubiquitously employed optic that dehumanizes racialized people), this dissertation asks: (1) What embodied practices …

Serial Position Effect Profiles And Their Neuroanatomical Correlates: Predictors Of Conversion To Alzheimer's Disease, Isabelle K. Avildsen

Dissertations, Theses, and Capstone Projects

The current study was designed to determine whether targeted, premorbid, neuropsychological measures of the serial position effect (SPE) can detect and explain risk for later development of Alzheimer’s disease (AD). The study tested the utility of SPE measures in healthy controls (HC) and individuals already diagnosed with mild cognitive impairment (MCI) or AD. Aim 1 was to determine whether these sensitive, valid neuropsychological measures can explain disease risk. SPE of list-learning are highly sensitive cognitive markers that capture important elements of both linguistic and amnestic mechanisms of encoding, learning, and retrieval. Using the Rey Auditory Verbal Learning Test (RAVLT), we …

Ssri-Induced Emotional Blunting: A Study Of Cognitive Changes In Pharmaceutically Treated Depression, Carly Tocco

Dissertations, Theses, and Capstone Projects

Objective: In recent years, approximately 12.7% of the American population are on a prescribed antidepressant medication. Selective Serotonin Reuptake Inhibitors (SSRIs) are a widely used pharmacological treatment for depressive and anxiety disorders, primarily due to their tolerance levels, mild side effects in comparison to other antidepressants, and broad range of clinical indications. However, there are still numerous concerns about SSRIs’ ability to improve depressive symptoms without adding side effects such as sexual dysfunction, gastrointestinal upset, and a restricted range of emotions. Although patients typically claim that they have less emotional pain while on SSRIs than they do during a depressive …

Problematic Social Media Use, Social Comparison, And Defeat: An Intensive Longitudinal Investigation, Natalia Macrynikola

Dissertations, Theses, and Capstone Projects

Self-injurious thoughts and behaviors (SITBs) have steadily risen over the past two decades. The simultaneous dramatic increase in social media use has fueled concerns that using social media may be contributing to suicide risk. Although an emerging body of evidence reveals associations between certain patterns of social media use and SITBs, most research studies have not been designed to assess the temporal order of these variables and have neglected to investigate mechanisms underlying such associations. As a result, whether and how social media use may be conferring suicide risk remains unclear. To address this gap, the present study examined a …

White Blinders: A Study Of Race Relations Theory In Britain, 1948–1988, Matthew T. Sherman

Dissertations, Theses, and Capstone Projects

This dissertation studies the early generation of scholars who developed the academic field of race relations in Britain from the 1940s into the 1980s. The research and methodology performed throughout this period was both innovative and problematic due to the approaches taken. Early scholars, such as Kenneth L. Little, Michael Banton, Sheila Patterson, and John Rex, provided the dominant schools of thought in the study of race relations in Britain up to the early 1970s. This dissertation studies the origins and development of an interdisciplinary field of study within the context of a nation and society coming to grips with …

The Politics Of Media Freedom, Kyong Mazzaro

Dissertations, Theses, and Capstone Projects

Democratization theories assume that democracy and media freedom go hand in hand. However, in democracies, politicians and individuals who have a stake in political battles often attack journalists. How can political and electoral incentives that are at the heart of democracy create a minefield for journalists? Examining cross-national patterns of censorship and the experiences of journalists in Venezuela, Mexico, and Brazil captured in over 4,600 case narratives, 30 field interviews, and historical documents, I study the circumstances under which political rivalries result in anti-media violence. I show that state and non-state actors are more likely to target journalists as a …

The Role Of Mortality Salience And Social Identity In Police Officers And Students Reporting Misconduct, Anna M. Stenkamp

Dissertations, Theses, and Capstone Projects

Over the past several decades, high-profile police shootings, police brutality, and police misconduct have contributed to a decreased trust in policing in the United States. Beyond the severity and abuse of power, many of these incidents have also revealed that officers have covered up these incidents from the public. The refusal of police officers to both report misconduct or cover it up is well established and known as the “blue wall of silence.” However, no previous studies have examined the psychological processes behind this failure to report fellow officer misconduct. Two psychological theories that may explain this failure are Terror …

The Storytelling Cure: Medicine And Narrative From Galen To Shahrazad And Rousseau, Ryan A. Milov-Cordoba

Dissertations, Theses, and Capstone Projects

Are stories healing? This dissertation introduces and explores an idea that I call “the storytelling cure.” With this term I capture a set of related notions about the healing power of stories that span literary studies, intellectual history, philosophy, and medical practice. Through a comparative study I make the case for “the storytelling cure” as a cross-cultural, multiconfessional, and multilingual phenomenon of great age, complexity, and power, worthy of the most sustained attention by the contemporary field of Comparative Literature. Concretely, this dissertation presents three extended case studies of “storytelling cures” from three different kinds of texts (case history, frame …

The T Visa Process And The Identification Of Victims Of Human Trafficking, Mandalena Prelashi

Dissertations, Theses, and Capstone Projects

The Trafficking Victims Protection Act of 2000 (TVPA) is a contemporary effort to combat human trafficking. In 2000, the Congress enacted the T Nonimmigrant Status (or T visa) in the effort to protect victims of trafficking and to enhance law enforcement’s ability to investigate and prevent these crimes in the U.S. This thesis explores from a legal and social point of view the obstacles, hurdles, and challenges that victims of human trafficking face, when applying for a T visa. I find that (1) victims assess their exploitation as wrong and immoral but not amounting to human trafficking, thus they are …

Exploring Social And Emotional Functioning In Emerging Adult Survivors Of Adverse Childhood Experiences, Sara Babad

Dissertations, Theses, and Capstone Projects

As many as two thirds of adults in the United States have experienced adverse childhood experiences (ACEs) and 60% of these individuals have experienced multiple, or cumulative ACEs. ACEs are associated with a range of outcomes, including social, emotional, and cognitive changes, health risk behaviors, psychopathology, worse physical health, and early death. Although some ACEs effects have been well-researched, social and emotional changes have received minimal attention in the literature in general. Research on ACEs effects in emerging adults (ages 18 to 25), an already vulnerable population, is also limited. Furthermore, there is debate in the field as to which …

Unexpected Arousal Suppresses Memory And Metamemory Predictions During Associative Face-Name Recognition Task, Sameer Sabharwal-Siddiqi

Dissertations, Theses, and Capstone Projects

Successful recognition often depends on probabilistic estimation of memory-signal. Arousal has been shown to offset the influence of heuristic evidence on memory prediction. We conducted three experiments that tested whether arousal also suppresses predictions relevant to memory confidence. Experiments employed associative face-name memory tasks that included retrospective (Experiments 1 and 2) or concurrent (Experiment 3) judgements of confidence. During test, subjects were presented with a masked-affective face on a subset of trials. By timing the masked-affective face to precede a recognition judgement (Experiment 1), we replicated the finding that unexpected arousal offsets the influence of heuristic evidence on expectations of …

Workforce Diversity And Health Equity: The Role Of Schools Of Public Health, Adashima Oyo

Dissertations, Theses, and Capstone Projects

The goal to eliminate health disparities and achieve health equity has remained a consistent public health and social welfare challenge for the United States. Schools of public health, despite being disproportionately White, are charged with the important task of training a diverse workforce of master and doctoral-level public health students to protect and promote the overall health of the nation with research, policy, and practice. Experiences and practices related to the recruitment, admission, enrollment, and graduation of students of color, specifically Blacks and Latinx, warrant further research. Positive deviance theory, critical race theory, and organizational culture theory informed this research. …

Competitive And Facilitative Interactions Between Pavlovian Cues In Human Associative Learning: A Behavioral And Neural Analysis, Fahd Alhazmi

Dissertations, Theses, and Capstone Projects

Learning to anticipate significant events accurately is a crucial element of survival for all species. The process by which animals acquire this knowledge has been a central question of psychological research. A fundamental assumption of many learning theories is that the predictive value assigned to cues is not simply determined by their probability of reinforcement but rather by their ability to compete with other cues present during learning. The assumption of cue competition has significantly contributed to the development of behavioral and neuroscience research for decades, as it has opened the door to new empirical and theoretical advances on the …

Desire Informing Philosophy In Plato: The Lover, The Tyrant, And The Citizen, Christian P. Bagrow

Dissertations, Theses, and Capstone Projects

Desire informs the good and examined life by giving meaning to and requiring training for human drives. In investigating Plato’s dialogues for how desire informs philosophy, comparison gives way to a genealogical hermeneutic; the obvious want to find changes or discrepancies in Plato’s texts, and Socrates’ words, gives way to interpreting congruent transformations of thought throughout his corpus. Specifically, this thesis evaluates desire’s multitude of signification and significance through the following the chronology: Symposium, Phaedrus, Republic, Statesman, and Laws. That human failing and ambition equally find desire couched between lack and satiation is radically reconsidered in the course of …

Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia

Dissertations, Theses, and Capstone Projects

Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …
