From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood

Dissertations, Theses, and Capstone Projects

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Targeting Ampa Receptor Modulation During Early Life Adversity: A Mediator For Threat Associated Memories, Roseanna M. Zanca

Dissertations, Theses, and Capstone Projects

Early life adversity (ELA) is the exposure to a single or to multiple traumatic events before the age of 18 that go beyond the child’s coping. These adverse events are often exacerbated during adolescence particularly when cognitive performance is compromised. Adolescents who experienced ELA may show symptoms of post-traumatic stress disorder (PTSD), while not vividly recalling the early life trauma. These individuals show atypical connectivity between prefrontal-amygdala and hippocampus, all of which is associated with an increased risk of experiencing a traumatic event again later in life. While clinical research has increasingly stressed the importance in addressing the long-lasting consequences …

This case study examines the difficulties faced by individuals diagnosed with Usher syndrome in their everyday life, including quality of life, safety, and social issues. Additionally, the non-medical benefits that leader dogs can provide such individuals is also presented.

Method: A thorough literature review was performed to provide background information regarding Usher syndrome and the impact it has on the hearing and vision of affected individuals. A related literature review was performed to examine the role …

A Lasting Impression: Higher Education’S Effects On Mass Polarization In The Us, Bradley Highfield

Dissertations, Theses, and Capstone Projects

Political polarization has been growing exponentially over the past few decades, not only with political elites and party activists, but also in the mass public. During the same period of time, the United States has also seen an exponential increase in higher education attainment. This paper examines the possible relationship higher education and elite political polarization may have in regards to the increasing polarization within the American electorate. Additionally, I aim to extrapolate how collegiate institutions create an increase in ideological polarization, as well as affective partisanship, while synthesizing Political Science studies on the effects of college education towards political …

Neuroplasticity Of The Corticospinal System: Applications Of Neuromodulation-Based Therapies, Alzahraa M. Amer

Dissertations, Theses, and Capstone Projects

The motor cortex and corticospinal tract are necessary for producing skilled movements. I use intermittent theta burst stimulation (iTBS), a high-frequency stimulation protocol known to promote neural plasticity, as a tool to characterize short- and long-term plasticity of the CS system.

Although it is well known that activity-dependent motor cortex (MCX) plasticity produces long-term potentiation (LTP) of local cortical circuits, leading to enhanced motor evoked potentials (MEPs), the effects produced by the corticospinal (CS) projection on spinal cord neurons have not yet been thoroughly studied. In Chapter 2, I determined if the CS tract (CST) is capable of producing LTP …

Microbial-Host Dynamics And The Evolution Of Nearshore Diversity In Hippocampus Abdominalis, Jimiane L. Ashe

Dissertations, Theses, and Capstone Projects

Local adaptation is a fundamental concept at the core of evolutionary process. Devising means to break down larger concepts and systematically test internal mechanisms are key to understanding the driving forces behind the influence of environmental differences on biological systems. To understand dynamic processes in the natural world, we must strip away layers and confounding variables that may mask the signal we hope to understand. In this case seahorse species, Hippocampus abdominalis, or the pot-bellied seahorse, made an unlikely but ideal study system. The first layer to strip away was neutral genetic variation within the population. A multilocus genetic …

Delayed Modulation Of Glutamate Receptors By Anti-Epileptic Drugs After Traumatic Brain Injury In Rats, Edgar Rodriguez

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a significant health concern. Around 74 million people sustain a traumatic brain injury worldwide. The damage caused by TBI produces two types of injury; primary and secondary injuries. Primary injury is caused within milliseconds and is irreversible. Secondary brain injury is delayed and produced by molecular, cellular, and structural disruption after the initial injury. One of the most devastating dysfunction after TBI is glutamate neurotransmitter overactivation that could lead to neurotoxic levels of glutamate in the brain (i.e., excitotoxicity). Excitotoxicity has been linked with the development of epilepsy after TBI, also known as post-traumatic epilepsy …

Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle

Dissertations, Theses, and Capstone Projects

Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …

Sartorial Semiotics: Constructs Of Gender And Female Sexuality In Post Wwii American And European Cinema, Patricia Cabral

Dissertations, Theses, and Capstone Projects

Cinematic costume design functions as a system of visually-perceived, material and indexical signifiers, an effective and compelling language further informed by styling and embodiment. Sartorial semiotics support and inflect role characterization, while equally underpinning or subverting tropes generated by ideological paradigms. The following methodological approaches were adopted in scrutinizing this topic: Roland Barthes’ application of semiotic theories to the domain of fashion in The Language of Fashion, and Laura Marks’ discussion of the dialectics of optical and haptic visualities in apprehending film images in The Skin of Film: Intercultural Cinema, Embodiment, and the Senses.

By examining the costume …

Remaking Cinema: Black Hollywood Films, Filmmakers, And Finances, Kiana A. Carrington

Dissertations, Theses, and Capstone Projects

The goal of my project was to create a dataset of black film that can be used for analysis of fiscal trends in black film. It includes the estimated budget, domestic and worldwide box office numbers for over 700 American black films. I defined black films as those that centered on African American stories and African American characters, or were made by Black filmmakers. I also included movies embraced by African American audiences that were made by non-Black filmmakers like Bad Boys, Django Unchained, and The Color Purple. I used a combination of Box Office Mojo, The Black Cinema Database, …

Prophecy, Emanation, And The Mediterranean Middle Ages, Alberto Gelmi

Dissertations, Theses, and Capstone Projects

This dissertation explores the notion of prophecy as a semiotic construct in Judaism, Christianity, and Islam on a chronological span that runs from Late Antiquity to the 14^th century. It argues that theories of prophecy offer useful insights in the domain of rhetoric and not just in epistemology, as scholarship has predominantly contended. The first two chapters survey the trendsetting work of Augustine, al-Kindi, al-Farabi, Ibn Sina, and Maimonides, arguing that their semiotic angle on prophecy depends on a structural affinity with the metaphysical template of emanationism as formulated by Plotinus and Proclus, whose teachings went often misrepresented or …

Challenges Of Repatriation: Asante Artifacts At The American Museum Of Natural History, Abdul-Alim Farook

Dissertations, Theses, and Capstone Projects

Inspired by calls for the repatriation of famous artifacts like the Benin Bronzes and the Elgin Marbles, for this capstone project, I have analyzed and catalogued 250 sampled Asante artifacts at the American Museum of Natural History (AMNH). Through this analysis, I discuss the many ways museums in North America acquired their collections. By doing so, I explore the difficulties that arise in debates surrounding repatriation due to the manner in which these artifacts were acquired. I argue that due to the many different types of donors of the Asante artifacts to the American Museum of Natural History, the Asante …

Skin Worlds: Black And Indigenous Science Fiction Theorizing Since The 1970s, Lou Cornum

Dissertations, Theses, and Capstone Projects

This dissertation unfolds along two trajectories, the first following from an ascendant interest in minoritarian traditions in speculative and science fiction and the second following the reiterative conversations across Black and Indigenous Studies. Science fiction theorizing is introduced as a frame for thinking these two trajectories together, with science fiction texts by authors Nalo Hopkinson, Octavia Butler, Gerald Vizenor, Leslie Marmon Silko and Samuel Delany providing a paraliterary mode of imagining the planetary from which to understand the interconnected processes of settler colonialism and trans-Atlantic slavery. Science Fiction theorizing across these texts disrupts notions of linear progressive time, human/alien boundaries, …

Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska

Dissertations, Theses, and Capstone Projects

Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …

Exposure Characterization And Assessment Of Airborne Chemicals And Sars-Cov-2 Transmission In New York City Nail Salons, Amelia P. H. Watkins

Dissertations and Theses

Background: Currently, there are 156,000 people employed as manicurists or pedicurists in the United States. Employment in this sector is expected to grow by 10% over the next decade. Exposure assessments have revealed that salon workers are chronically exposed to a variety of substances that cause respiratory sensitization, developmental problems, contact dermatitis, blood, liver, and kidney issues, as well as nervous system impacts. Most recently, the SARS-Cov-2 pandemic has raised the issue of the vulnerability of nail salon workers to airborne infectious diseases as well. This dissertation aims to characterize and assess the chemical exposures that nail salon workers …

Mechanistic And Synthetic Studies Of Oxidopyrylium Cycloaddition Reactions, Lauren P. Bejcek

Dissertations, Theses, and Capstone Projects

Cycloaddition chemistry has historically served as a robust route to stereo-rich and highly functionalized cyclic and heterocyclic compounds. Herein we describe our examination of 3-hydroxy-4-pyrone-derived oxidopyrylium cycloadditions in both mechanistic considerations as well as the unique synthetic advancements of their corresponding cycloadducts. Chapter 1 is a literature review where we specifically outline the use of oxidopyrylium cycloadditions in the synthesis of natural products. This includes the mention of previous syntheses prior to 2008, and a more thorough examination of the natural products synthesized from 2008 to present. The work exploits this chemistry as a facile route to highly complex 7-membered …

Synthetic And Biological Studies On Benzazepine Derivatives As Dopamine Receptor Ligands, Rajan Giri

Dissertations, Theses, and Capstone Projects

Dopamine (DA) receptors, members of the G-protein coupled receptors (GPCRs) family, are divided in two groups based on their transmembrane structural homology domains: D1R-like (D1R, D5R sub-types) and D2R-like DA receptors (D2R, D3R and D4R sub-types). Disturbances in dopaminergic neurotransmission are associated with several CNS disorders. Hence, DA receptor selective ligands have been sought as pharmacological agents to normalize perturbations in the dopaminergic system. Despite several notable efforts, the discovery of highly selective ligands for dopamine receptor sub-types has proved challenging due to close transmembrane structural similarity, especially between DA receptor sub-types within the same group.

The 1-phenylbenzazepine scaffold is …

Gay For English: Postcolonial In(Queer)Ies Into Contemporary Hindi Cinema, Hardik R. Yadav

Dissertations, Theses, and Capstone Projects

In this thesis, I study four recent Hindi-language Indian films for what I see as their queering of the English language, and, in turn, putting the Indian entity at a distance from both language and sexual orientation. The nation-making project of the Hindu political right in India today seeks an identity in distance from the English language: closer to the age-old conception of India as Hindustan (place of the Hindus). In Part I, I explore how such a resistance to English allows for the “Indian” within male protagonists of Rajat Kapoor’s Ankhon Dekhi (2013) and Aanand L. Rai’s Raanjhanaa (2013) …

Social Production Of Intellectual Disability And The Mechanics Of Moral Exclusion: Past, Present, And Future, Emese Ilyes

Dissertations, Theses, and Capstone Projects

The institutionalized dehumanization in the United States continues to allow for people who are categorized as intellectually disabled to be legally warehoused and paid as little as pennies per hour to complete rote, repetitive work within segregated environments. An entire court case was conducted about whether a man labeled as intellectually disabled was able to engage in a consensual relationship or whether he was the victim of sexual assault without ever allowing him to express his desires and lived experiences. This project is an attempt to explore a theoretical, historical explanation for how humanity is denied in some bodies, how …

Essays On Universal Basic Income, Nana Mukbaniani

Dissertations, Theses, and Capstone Projects

Universal Basic Income (UBI) is a program in which individuals receive a regular sum of money, usually from the government. The transfer amount is thought to be unconditional of income and enough to cover all subsistence needs. Such a system is easy and cheap to administer because the government does not need to check the eligibility of each applicant. UBI programs are growing as more cities, states and countries (Stockton, California, Newark, New Jersey, Ontario, Canada, Kenya, Finland, Germany, Spain, China, etc) implement experiments of such programs. The idea of a UBI is gaining ground in the U.S.. One of …

Dissertations, Theses, and Capstone Projects

This work investigates the emergent nature of research on emotions and wellness in early childhood education and in life. The research discussed in this thesis was emergent and contingent. Through my experiences as an educator, student, mother, human being living through a pandemic, and daughter, I embraced opportunities for research in various fields of my life.

I explore teaching research to early childhood teachers who also became my coresearchers in a project that explores our roles of being teachers | researchers. Together, using a hermeneutic-phenomenological approach, we learn about the experiences of those participating in the research projects, both individually …

The Rainforest Is Burning: Trials And Triumphs Working Towards Conservation In Rural Madagascar, Kathryn Alessi

Dissertations, Theses, and Capstone Projects

In late 2019, I spent almost four months in Ranomafana, Madagascar, a region in the southeast that houses tropical rainforest. The research I conducted is not analyzed in this capstone. Instead, I decided to write about my personal experience through a series of reflections that explore the difficulties I faced, as well as the moments of joy. Much of the information presented in this capstone and white paper come from my own experience and copious conversations I had with other people in Madagascar. Several of these conversations were recorded in my diary and fieldnotes, but most were recounted from my …

Vulnerability: Sensation And Subjectivity In The Late Victorian Novel, Michael Shelichach

Dissertations, Theses, and Capstone Projects

“Vulnerability: Sensation and Subjectivity in the Late Victorian Novel” explores how developments in the science of psychology in the second half of the nineteenth century destabilized the genre of literary realism in Britain. Prominent mid-Victorian psychologists theorized a subject with a highly impressionable brain and nervous system. This new understanding of the mind’s potential vulnerability to external influence impelled contemporary novelists to contemplate the extent to which subjective interiority could be altered by the environment. Through close readings of canonical realist novels like Charles Dickens’s Great Expectations, George Eliot’s The Mill on the Floss and Wilkie Collins’s The Moonstone …

The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria

Dissertations, Theses, and Capstone Projects

Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …

Object Expression: Diligent Realism In The Works Of Roland Barthes, Elena Ferrante, Karl Ove Knausgaard, Valeria Luiselli, And W. G. Sebald, John Knight

Dissertations, Theses, and Capstone Projects

In the past twenty years, ambiguous yet meaningful encounters with objects have become a trope in contemporary fiction. Collections and archives, found objects and commonplace articles of modern life have especially substantiated literature that engages themes of displacement and selfhood. The method of incorporating objects into these works ranges from explicit cabinets of curiosities to more subtle appearances, but in each case material reality is the conduit for fundamental expressions of character. These authors draw the reader’s gaze toward an object as a way to indirectly articulate subjective experience, conspicuously displacing the central concerns of a text. This study examines …

The Role Of Placental Genes On Intellectual Disability And Developmental Delay, Maedot A. Yidenk

Dissertations, Theses, and Capstone Projects

The complex interaction between gene expressions and environmental factors plays a key role in the pathogenesis of various diseases, including neurodevelopmental disorders (Lenroot & Giedd, 2008). This study aimed to evaluate first, the magnitude of association between placental gene Methyl-CpG Binding Protein 2 (MeCP2) and intellectual disability (ID) in the offspring and second, the synergy between placental gene Forkhead box protein 1(FOXP1) and developmental delay (DD) in the offspring. We focused on assessing two specific paradigms, i) placental gene expressions of MeCP2 among children that have ID vs. children without ID; and ii) placental gene expression of …

How Are Refugees Depicted In The Amarillo Globe-News?, Shannon Reimers

Dissertations, Theses, and Capstone Projects

This research uses media analysis to ask how refugees in Amarillo, Texas, are portrayed in the Amarillo Globe-News from 2002 until January 2021. Amarillo, Texas is a small, conservative city with a long history of refugee resettlement. Researching one town, over an extended period, tells a rich story of how refugees are depicted in the local media. This research is important because while the United States takes in refugees on a national level, the local level is where they settle and become long-term members of a community. It shares what a community resettling refugees has to say about them. In …
