Rainforests Of The Mind: Conceiving Transnational Composition From A Mobilities Perspective On Knowledge., Tobias Lee

Electronic Theses and Dissertations

This research project stems from my experience teaching academic writing at the state university in Qatar. To investigate the factors overdetermining the deeply standardized curriculum there, I draw on scholarship in mobility studies, political economy, and the history both of Qatar and of composition instruction in the US, from which the curriculum is drawn. These explorations ultimately lead me to comment on the fraught enterprise of subjecting writing and language to commodification, which I identify as part of broader trends characterizing neoliberal economic globalization. To further develop this critique, I conduct a critical multi-sited autoethnographic study that questions preconceived notions …

Perineuronal Nets Are Not Required To Close The Critical Period For Ocular Dominance Plasticity., Emily Crouse

Electronic Theses and Dissertations

In the developing visual system, a transient critical period demarcates when neural circuits are most sensitive to visual experience. In the mouse, the critical period occurs between approximately postnatal day(P) 19 to 32. Closing one eye (monocular deprivation, MD) within the critical period shifts ocular dominance (OD) to be more responsive to the open eye. Nogo-66 Receptor 1 (NGR1) limits OD plasticity to the critical period yet it remains unknown how OD plasticity propagates through primary visual cortex or by which mechanisms NGR1 utilizes to confine said plasticity. In primary studies, NGR1 was selectively deleted in different cortical layers to …

Someone, Stop Her! The Musical (The Gallery Show): The Thesis Document., Hannah Dewitt

Electronic Theses and Dissertations

This thesis document accompanies a body of work that is radically vulnerable, personally political, and emotionally complex. Through my work, I challenge myself and my audience to sit with discomfort and create an environment suitable to generate a nuanced appreciation of pain that approaches its acceptance through humor, confessionalism, and the subversion of tropes against themselves as an act of counter-mimicry. This document situates my work within art-historical context with a primary focus on performance art and applies insight from each artwork referenced to further analyze and defend my own work. Additionally, I use texts relating to Camp sensibility, binary …

Chemosensory Processing By The Mediodorsal Thalamus., Kelly Fredericksen

Electronic Theses and Dissertations

The mediodorsal thalamus (MD) is thought to be key component of the network that processes chemosensory information to guide our consummatory choices. Previous studies show that the mediodorsal thalamus receives projections from both the piriform cortex (PC) and gustatory cortex (GC), suggesting that it may process chemosensory information from both areas. Although the mediodorsal thalamus has been shown to respond to odors detected by sniffing, it remains unknown how its neurons represent experienced odors, tastes, and odor-taste mixtures originating from the mouth. Importantly, humans and animals with mediodorsal thalamic lesions do not suffer from anosmia, but experience deficits in odor …

Supraspinal Reorganization After Pediatric-Onset Spinal Cord Injury., Luis Alvarado

Electronic Theses and Dissertations

Pediatric spinal cord injury (SCI) disrupts the efferent and afferent flow of the developing brain, leading to devastating functional impairments below the injury site, yet our understanding of its impact on the brain remains limited. This study examines supraspinal reorganization in children with SCI using electrophysiology and neuroimaging techniques to understand the relationship between residual spinal transmission and supraspinal reorganization. Chapter 2 discusses the development of a child-centric approach using ‘learn, play, and practice’ to foster a trusting relationship with each child and increase compliance with experimental protocols. Chapter 3 evaluates the residual neural transmission of three spinal pathways in …

The Evolution Of Empathy: Through The Lens Of A Rodent Model., Caroline Driscoll-Braden

Electronic Theses and Dissertations

Empathy is the capacity to be affected by and share the emotions of others, to discern the circumstances prompting another’s emotional state, and to identify with another by adopting their perspective. Research investigating the empathically motivated behavior of rats can help inform the evolutionary history of empathy and provide additional support of the continuity of empathy in animals and humans. In this dissertation, I examine the helping behavior of rats to explore the complexities of rodent empathy. In Chapter I, I review the multiple layers of empathy and describe both historical and contemporary research examining empathy in non-humans. I explain …

Guided Data Augmentation For Improved Semi-Supervised Image Classification In Low Data Regime., Fadoua Khmaissia

Electronic Theses and Dissertations

Deep learning models have achieved state of the art performances, especially for computer vision applications. Much of the recent successes can be attributed to the existence of large, high quality, labeled datasets. However, in many real-world applications, collecting similar datasets is often cumbersome and time consuming. For instance, developing robust automatic target recognition models from infrared images still faces major challenges. This is mainly due to the difficulty of acquiring high resolution inputs, sensitivity to the thermal sensors' calibration, meteorological conditions, targets' scale and viewpoint invariance. Ideally, a good training set should contain enough variations within each class for the …

Barriers And Facilitators Of Dairy Consumption Among Individuals With Metabolic Syndrome., Kofi Amoh-Mensah

Electronic Theses and Dissertations

About 35% of the United States adult population meets the criteria for metabolic syndrome, representing about 85 million individuals. Consuming dairy products protects against the development of the metabolic syndrome and protects against the development of complications associated with it. However, approximately 10% of the U.S. population meets the daily recommendation for dairy products. Information about the use of dairy products among people living with metabolic syndrome is relatively unknown, even though it will benefit them the most. About 49% of respondents met the guidance of three servings per day, and the most common facilitator was access to dairy products.

Children's Beliefs About Hierarchical Structures And Relationships., Megan Norris

Electronic Theses and Dissertations

Children are surrounded by social structures such as families, schools, and workplaces which are often arranged hierarchically with some people holding more power than others. This dissertation explores how children think about hierarchical relationships and more complex hierarchical structures. In Chapter 2, children were asked to evaluate the traits of people who hold hierarchically dominant and subordinate social roles. With age, 4- to 6-year-olds increasingly inferred that dominant individuals have social power and they deferred to their instructions (Chapter 2, Study 1). Furthermore, 5- and 6-year-olds attributed knowledgeability to individuals with dominant social roles but overall children did not prefer …

Second Nature: Impressions Of Place., Trish Korte

Electronic Theses and Dissertations

For my art practice, I grow and forage my art materials for eco printing, a direct contact printing method that reveals leaf shapes and hidden imagery through heat and pressure. I take specific cues from surrounding materials, objects, and environments. Tree systems and compelling textures of fungus are interpreted through ceramic and fiber. With an ongoing collaboration of natural materials and eco printing processes, my art speaks symbolically and metaphorically through imagery and materials. This thesis and accompanying exhibition present an examination of current work in context with an ongoing investigation of natural materials and eco printing.

Toward A Comprehensive Account Of Orientation Selectivity In The Retina., Megan Zipperer

Electronic Theses and Dissertations

Retinal Ganglion Cells (RGCs) form functionally distinct signaling channels that selectively encode features of the visual input including direction of motion, contrast polarity, size, and color. A highly conserved visual channel amongst vertebrates conveys orientation selectivity, i.e., the selective firing of neuronal cells in response to elongated stimuli along a preferred orientation. Orientation selectivity is an apparent critical computation and several studies have reported aspects of it, including cell type identity in anatomical reconstructions, and functional characterization of at least four different identified RGC types. But how cell types in the different studies relate is not well resolved; the mechanisms …

Menstruation Stigma: A Qualitative Exploratory Study Of The Lived Experiences Of Nepali Women., Imisha Gurung

Electronic Theses and Dissertations

Despite the numerous challenges and barriers that menstruation taboos and stigma pose to the health and well-being of Nepali women and girls, this problem has received little attention in Nepal and has been under-researched. This study fills a critical gap in our understanding of the lived menstruation experience of Nepali women utilizing a qualitative descriptive approach in Kathmandu, Nepal. The data collection comprised in-depth, semi- structured interviews with 22 Nepali women. The findings provide various influencing socio- cultural factors at multiple levels of socioecological model that shapes the lived menstruation experiences of Nepali women and the impact on their mental, …

Epicertin: Preclinical Development Of A Novel Mucosal Healing Agent For Ulcerative Colitis., Micaela Reeves

Electronic Theses and Dissertations

This dissertation describes the development of a biotherapeutic agent, EPICERTIN, that fulfills an unmet treatment need for ulcerative colitis (UC): mucosal healing. EPICERTIN is a recombinant cholera toxin B subunit (CTB) variant with a KDEL endoplasmic reticulum (ER) retention motif that is crucial for its wound healing capabilities. Previous studies have demonstrated that EPICERTIN’s mucosal healing activity is due, in part, to its prolonged residence in the ER which initiates an unfolded protein response (UPR) and subsequent TGF-β signaling and barrier repair in colonic epithelial cells. This activity was demonstrated in a dextran sulfate sodium (DSS) colitis model as well …

Impact Of Employee-Supervisor Attachment Styles On The Prevalence And Symptomatic Expression Of Secondary Traumatic Stress In Public Child Welfare Workers., Lisa Purdy

Electronic Theses and Dissertations

Child welfare organizations throughout the nation grapple with turnover rates estimated to be as high as 65% (e.g., CWLA, 2016; Edwards & Wideman, 2018). Turnover contributes negatively to client outcomes, organizational financial shortages, and to perpetuating stressful conditions for the child welfare workforce. One factor found to contribute to turnover within child welfare is that of secondary traumatic stress (STS). Child welfare workers are known to experience higher rates of STS than any other helping professional (Brady, 2017). However, while many risk and protective factors for secondary traumatic stress have been evaluated, there remains a gap in the literature as …

Our Story, Our Song: Assessing And Addressing Black Women's Healthcare Experiences., Jason Deakings

Electronic Theses and Dissertations

Despite advancements in medicine and health sciences, health disparities and declining life expectancy persists among Black women in the United States. Researchers and non-traditional healthcare providers suggest alternative healing (e.g., music and Sister Circles) and research methodologies to achieve a culturally conscious, traumainformed, quality, and holistic care and practice. The intersecting identities and cultural responsibility of Black women highly influences the barriers and facilitators on the uptake of healthcare services. Utilizing a community engaged research approach, this qualitative study assessed the healthcare experiences, as well as the role of music in the lived and retold experiences of Black women navigating …

Fear Of Becoming A Victim Of Crime On A College Campus: A Visual And Factorial Experimental Design Survey Analysis Of Location And Demographic Factors., Nancy Steinmetz

Electronic Theses and Dissertations

Vanessa LoBue (2013) states that the emotion of fear, “a signal of impending threat” (p. 38) is common among mammals. For over five decades, there has been substantial research into what in society, or our communities, makes us fearful. It is this author’s intention to examine how college students’ fear of crime or fear of victimization may be heightened or intensified by specific factors that are commonplace on college campuses and areas adjacent to those campuses. Nicole Rader (2004) argues that the fear of crime discourse needs to be expanded to a larger “construct” called “the threat of victimization” (p. …

Still Got The Blues - No Time But Here, No Place But Now: Geographies Of Art & Activism In The Work Of Clyde Woods., Jake Mace

Electronic Theses and Dissertations

The fight against displacement and dispossession in the increasingly inequitable process of reterritorialization is arguably the most pressing struggle of the modern city – and it is articulated through cultural production as much as through political debate and economic development. Yet research that is at the nexus of critical, urban, and cultural studies and which explores the resistant potential of countercultural production rather than the hegemonic impact of mainstream cultural production is underdeveloped. Clyde Woods’s blues epistemology offers a guide to reading cultural production of marginalized groups as maps of meaning that offer alternative visions of the past, the present, …

Hsp90 And Triglyceride Levels In Partially Migratory Canada Geese (Branta Canadensis) Populations, Audra Cote

Departmental Honors & Graduate Capstone Projects

The Canada Goose (Branta canadensis) is a partial migrant species, which means that some individuals migrate between breeding and nonbreeding grounds, while others remain in one location throughout the year. Eastern Virginia contains both permanent residents and overwintering migrants which breed in Canada's James Bay region. The metabolic demands of migration predict physiological differences between migrants and more sedentary residents, but they have been little studied in Canada Goose. Understanding such differences may help predict the resiliency of migratory birds to rapid climate change. We compared triglyceride and HSP90 (heat shock protein) in liver tissue extracted from resident and migrant …

Paradigms Of The Post-Natural: Depicting Alternative Futures, Andrea De Haro, Charlotte Bascombe

Architecture Senior Theses

Paradigms of the Post Natural is a thesis that utilizes imagery and storytelling to critique present practices of design which disregard the protection of our environment. We are interested in current environmental degradation characteristics of the era of the anthropocene where human-centric design methods have manipulated and exploited the ecosystem in which we coexist with other organisms as destructive pursuits of human development. Our inspiration developed from a shared interest in the conservation of non-human organisms. Specifically, we are interested in ecocides, areas in which animals are forced to adapt as they experience the human destruction of their habitat. Examining …

Toxic Glacier: Confronting Our Society's Consumerism Culture, Valeria Otero Lopez

Architecture Senior Theses

This thesis is situated in the scenario of a dysfunctional society in which States refuse to cooperate with one another, and every State refuses to import NYC’s waste.

I’m proposing the implementation of a waste treatment plant that processes waste into a “Toxic Glacier” in Central Park, which was originally developed as a place to escape from the overcrowding and polluting streets. Because of the tremendous size this would conquer, there is nowhere in NYC to execute the project but the park.

This project uncovers the City’s hidden motives for concealing waste from its inhabitants. It questions the City’s intentions …

Analysis Of Genes Responsible For Neuronal Morphological Changes In Down Syndrome Hipsc-Derived Neurons, Juhi Patel

Senior Theses

Down syndrome (DS) is a complex neurodevelopmental disorder caused by the trisomy of chromosome 21. DS is the largest genetic cause of intellectual disability, which occurs in varying severity among affected individuals. It is associated with a variety of developmental and cognitive defects, including reduced brain size, impaired synaptic function, and altered neuronal morphology. A number of genes have been identified to play critical roles in the development and maintenance of neuronal morphology, and alterations in the expression of some of these genes are implicated in the morphological changes observed in DS. Knocking out or altering their expression leads to …

Investigation Of Microplastics In River Bottom Sediment Along The Musconetcong River, Nicole Perkins

Theses, Dissertations and Culminating Projects

The knowledge of microplastics remains limited since there are scientific challenges in understanding long-term effects and health risks associated with microplastics in all environments. Challenges associated with microplastics investigations include limited approaches to microplastics sampling and analyses, understanding long‐term behavior of microplastics, the organismal and ecosystem health risks, and finding alternatives to using plastic. The research on microplastics has focused mainly on microplastics abundance and distribution in the environment, while their transport and pathways have remained rather understudied. The goal of this study was to expand our knowledge of microplastics in river sediment.

This microplastics investigation consisted of sampling the …

An Unfaithful Feminist : Neoliberal Feminism, Identity, And Postmodernism In Jenny Offill’S Dept. Of Speculation, Anne Bobis

Theses, Dissertations and Culminating Projects

Jenny Offill’s novel Dept of Speculation explores the life of a female college professor who looks back on her marriage after her husband has an affair. Events are told through brief fragments. Much of the critical discourse surrounding the novel is concerned with its fragmentary form or postfeminism. In this essay, I assert that Dept. of Speculation is a reaction to neoliberal feminism because of the narrator’s multiple challenges throughout the novel. Some vocal figures within neoliberal feminism assume a woman can balance upward mobility in a career and life as a mother. The ability to maintain this work-life balance …

An Assessment Of Information And Education As A Factor Of Agricultural Development And Sustainability In South Carolina, George Strickland

All Theses

Across the Southeastern United States, producers in the agricultural industry wage a constant struggle between combating negative economic impacts and discovering economic opportunity. Harmful Algal Blooms (HABs) represent a crisis with wide-ranging economic impacts. The management of HABs presents a critical challenge for addressing the level of knowledge (LOK) and adaptability of Extension agents. Conversely, the emergence of markets for local and organic produce represents a burgeoning economic opportunity for producers. The growing trend of including more kale in the everyday American diet demands an assessment of those opportunities for local producers.

To identify the WTP for organic and local …

Dreams and nightmares feature prominently in art, story, and religious practice and tradition throughout history. In this paper I will discuss their prominence throughout these facets in daily life, and the various ways that we, as humans, have tried to elucidate meaning from them. I will study the nature and definition of dreams and nightmares through a scientific, cultural, and historical approach. I will also discuss folklore and the interpretation of nightmarish imagery in the context of an otherworldly adventure through a nightmare. These topics and themes will be shown, explained, and discussed through the methodology of my project- a …

A Systematic Review Of Research On Treatment & Prevention Of The Neglected Tropical Disease Leishmaniasis, Aryn Akerberg

All Theses

Leishmaniasis is a life-threatening neglected tropical disease that is caused by the protozoa parasite, Leishmania. Over one million new human leishmaniasis cases occur each all over the world, affecting most the deeply impoverished regions of the world. The disease presents in three different forms: cutaneous leishmaniasis, mucocutaneous (mucosal) leishmaniasis, and visceral leishmaniasis. Symptoms can range from self-limiting lesion to more life-threatening conditions such as fever, kidney disease, and anemia. The Leishmania parasite is transmitted via the bite of the female phlebotomine sandfly and can infect many other mammals such as canines, rodents, bats, etc. The canine leishmaniasis epidemic is also …

A Multi-Lab Experimental Assessment Reveals That Replicability Can Be Improved By Using Empirical Estimates Of Genotype-By-Lab Interaction., Iman Jaljuli, Neri Kafkafi, Eliezer Giladi, Ilan Golani, Illana Gozes, Elissa J Chesler, Molly A. Bogue, Yoav Benjamini

Faculty Research 2023

The utility of mouse and rat studies critically depends on their replicability in other laboratories. A widely advocated approach to improving replicability is through the rigorous control of predefined animal or experimental conditions, known as standardization. However, this approach limits the generalizability of the findings to only to the standardized conditions and is a potential cause rather than solution to what has been called a replicability crisis. Alternative strategies include estimating the heterogeneity of effects across laboratories, either through designs that vary testing conditions, or by direct statistical analysis of laboratory variation. We previously evaluated our statistical approach for estimating …
