Nerve Repair Chamber, Theodore Bronk, Gracyn Campbell, Reeham Choudhury, Joshua De La Cruz, Basile Montagnese, Yutong (Linda) Xia

ENGS 89/90 Reports

Peripheral nerve injury can lead to severe loss of motor control or sensory integration, posing a significant decrement to quality of life. Yet, using traditional approaches to repair, maximal recovery can take up to 2-3 years to achieve with fewer than 50% of patients ever recovering acceptable sensory and motor function. There is a need to increase axonal alignment while also preventing Wallerian Degeneration of the distal end of the nerve to improve repair. We developed a nerve coupler to be used in a rat sciatic nerve model that holds proximal and distal ends of a nerve together while allowing …

Sustainability Verification, Paul Rose

American University Law Review

From the earliest stages of the sustainable finance market and of green, social, and sustainable debt as an asset class, sustainability verifiers have been essential to the market’s function. Sustainability verifiers—professional service providers who provide an external review of an issuer’s alignment with established green bond frameworks—play a crucial role in reducing information asymmetries between sustainable finance instrument issuers and investors and serve as reputational intermediaries that assure buyers of the seller’s green, social, and sustainability-centered commitments. Yet, despite their essential function in facilitating the investment of trillions of dollars in green, social, and sustainable finance investments, the role and …

"Never Let A Good Crisis Go To Waste": Can International Law Seize The Advantage?, Yves Daudet

American University International Law Review

Some international crises are circumscribed, others are more diffuse, sometimes of varying intensity depending on the region. But, at the end of the day, all regions might be impacted according to an uncertain timetable. This is the case, for example, with terrorism, cybersecurity, the migration crisis, and the climate crisis, which is one aspect of environmental damage that intersects with the health crisis. Some are latent and marked by sudden outbreaks, such as terrorism or the Islamic State’s criminal operations. Others are set to worsen, such as the migration crisis, which today is probably small compared to what it will …

Examining The Effects Of Synthetic Dye Yellow No. 5 (Tartrazine) Exposure On Mouse Neuro2a Neurons In Vitro, Jenna L. Farnum

Honors Undergraduate Theses

Yellow Dye No. 5, also known as tartrazine (TRZ), is widely used[1] and has an accepted daily intake (ADI) of 0-7.5 mg/kg of body weight per day^[2]. Consuming TRZ dosages greater than the ADI can lead to reduced levels of antioxidant enzymes in the brain, chromosomal alterations, or neuronal dendritic changes, [3, 4] which can result in oxidative stress, impaired neuronal functioning and potential mutagenic effects. Within the ADI, there have been observed reductions of the copper zinc superoxide dismutase-1 (SOD1) enzyme levels.[5]We hypothesize that TRZ interacts pre-translationally inside the cell, resulting in the reduction of SOD1 mRNA. …

Investigating The Relationship Between Biological Age And Mutant Huntingtin Misfolding, Ratnesh Kesineni

Honors Undergraduate Theses

Huntington Disease (HD) is an autosomal dominant neurodegenerative disease caused by an expansion of a CAG trinucleotide repeat tract in the huntingtin (HTT) gene. This CAG tract expansion causes production of mutant HTT (mtHTT) protein, which misfolds and forms inclusions in the brain that accumulate with age. Misfolded mtHTT aggregates have been linked with increased cell death in neuron cell culture, leading to speculation that mtHTT aggregates cause cell death. However, there are mouse lines that have robust mtHTT inclusion deposition, but no HD-like signs or neurodegeneration. Furthermore, neuronal HD cultured cells with inclusions were found to be …

Examining The Prevalence And Representation Of Diverse Populations In Children's Literature Found In Elementary Classroom Libraries, Trishell M. Matthews

Honors Undergraduate Theses

The intent of this thesis is to (1) examine the prevalence of diverse populations in the pieces of children’s literature found in three Title I third grade classrooms, and (2) to examine if the diverse populations are authentically and relevantly represented. Researchers have emphasized the impact and importance of children’s literature that represent student’s diverse backgrounds authentically and relevantly, as they have the potential to affect students’ motivations, aspirations, and how they view themselves and the world at large. Particularly, Bishop (1990) suggested that students need books that act as “mirrors” that allow them to see themselves, their experiences, and …

Novel Microbe-Resistant Clay Dressing For Healing Burn Wounds, Kasey L. Rigby

Honors Undergraduate Theses

Every year, about 550,000 patients receive medical attention for minor and major burns in the United States.¹ In 2020, it was estimated that 11 million people worldwide suffered from burn injuries, with 150,000 of those burns being fatal.² Burns are among the most painful and debilitating recalcitrant wounds that can often turn terminal when infection occurs. The different grades for burns that we aim to treat are first, second, and third degrees.² Each burn type is susceptible to secondary infection that can be life threatening, and as a result, are extensively treated with antimicrobial agents.2 At present, …

The Role Of Individual Differences And Personality Factors In Distracted And Aggressive Driving Behaviors, Alyssa M. Holcomb

Honors Undergraduate Theses

Government reports indicate that, on average, more than 3000 people die due to distracted driving each year, accounting for nearly 10% of all fatal car crashes. Other reports claim that two-thirds of fatal car accidents result from aggressive driving. Previous research has been inconclusive regarding how personality impacts distracted and aggressive driving behaviors. Therefore, the goal of this current study is to fill the gap in the literature concerning the role that personality plays in distracted and aggressive driving behaviors. We also explored the role that distracted and aggressive driving behaviors played in accident involvement. A sample of (N=327) participants …

The Maine lobster industry and Wabanaki communities in Maine are used as two examples for resource management systems. The Maine lobster fishery is known for being one of the most sustainable fisheries in the world. Their history is examined for how their environmental values and social norms influenced their behavior and what led to the establishment of their strong conservation ethic. Wabanaki groups in Maine are …

Effects Of Mental Health Disorders On Time Perception, Mirella S. Galliano-Rechani

Honors Undergraduate Theses

Research suggests a relationship between time distortion and mental health disorders, and the present study sought to examine this proposition. Prior research suggests that negative emotions are associated with the slowing down of time. Because mental health disorder symptomology is associated with more negative emotions, it was predicted that negative emotions would mediate the relationship between mental health disorder symptomology and time distortion. A survey was administered to university students that contained measures of anxiety, depression, emotional experiences, and time perception. Mental health disorder symptomology was found to be related to negative emotions. However, negative emotions and mental health disorder …

Exploring The Relationship Between Nutrition And Cribra Orbitalia: The Comparison Of Dietary Stable Isotope Comparisons Of Juveniles From Kuelap, Peru, Lissette S. Osorio

Honors Undergraduate Theses

A juvenile’s dependency on their caregiver is significant to the overall development of nutritionally related pathological lesions. However, not all skeletal pathology is caused by nutritional stress; despite anemia being the usual inferred cause, the origin of Cribra Orbitalia (CO) – lesions on the orbital roofs of the cranium– is undetermined. The purpose of this research is to compare the reconstructed diets of juveniles with and without CO and explore connections to dietary patterns (inferred from stable isotope ratios of carbon and nitrogen). Rib bone samples of 79 juveniles with and without CO were sampled from the Kuelap archaeological site …

Exceptional Driving Principles For Autonomous Vehicles, A. D'Amato, S. Dancel, J. Pilutti, L. Tellis, E. Frascaroli, J. C. Gerdes

Journal of Law and Mobility

Public expectations for automated vehicles span a broad range, from mobility for passengers, to road user safety, to compliance with the traffic code. In most ordinary situations, these expectations can be satisfied simultaneously. But these various expectations can also lead to exceptional scenarios where certain objectives, such as those related to safety, are in tension with road rules. Exceptional driving scenarios challenge motion planning algorithms in automated vehicles to find solutions that are legally grounded, ethically sound, and technically feasible.

The general public’s familiarity with exceptional driving scenarios comes from the classic "Trolley Car" problem in philosophy, asking who should …

Jemimas, Jockeys, And Jolly Banks: The Racial Discourse Of Black Collectibles, Conrad Pruitt

CGU Theses & Dissertations

Over the last thirty years, an industry in black racist memorabilia has resurged. Bolstered by online commerce, social media trade, and a robust reproduction market, racist collectibles continue to circulate despite their functional obsolescence or presumed incongruity with current views of race. Many of these objects originated in the late nineteenth century, where the emergence of black citizenship was seen as a threat to a racial caste structure that ensured white supremacy. Following the impetus for supremacy that defined the Jim Crow era, the collectibles sought to crystallize conceptions of inherent black inferiority. The presumption that these originary conditions and …

This is accomplished through a process of synthesis and application. The intersection of environmental destruction and gender disparity is the hallmark claim of ecofeminism and thus, I begin …

The Pervert’S Guide To The Museum, Seth Ifor Alt

CGU Theses & Dissertations

This dissertation provides a sustained theoretical articulation of core Lacanian psychoanalytic concepts situated within the standing difficulties in the practice and theory of museums. Drawing upon research gathered from site visits, informational interviews, textual analysis, and an extensive engagement with the seminars of Jacques Lacan, I enumerate here a first attempt at what a Lacanian theoretical formation can contribute to museum studies scholarship. Through this research this dissertation shows psychoanalysis to be especially useful for museum studies owing to how the troubles immediately encountered in the everyday material practices of museological work are structurally analogous to the impossibilities experienced on …

An Exploratory Analysis Of How Maya Angelou, Audre Lorde, And Patrisse Cullors Radicalized The Meaning And Practice Of Self-Care, Melanie Marie Lindsay

CGU Theses & Dissertations

My dissertation, “An Exploratory Analysis of How Maya Angelou, Audre Lorde, and Patrisse Cullors Radicalized the Meaning and Practice of Self-Care”, hypothesizes that we can conceive a practice of self-care using an abolitionist lens to examine the writings and performances of three Black feminists Maya Angelou, Audre Lorde, and Patrisse Cullors. Abolitionist self-care is a response to the political structures that directly affect marginalized communities, and it evaluates the numerous ways that Black women have used their voice to challenge systems of oppression. If we examine their thinking as expressed through their poetry, their performances (including activism), and their self-life-writing, …

The Nutritional Condition Of Moose Co-Varies With Climate, But Not With Density, Predation Risk, Or Diet Composition, Jennifer S. Forbey, Daniel P. Melody

Biology Faculty Publications and Presentations

A fundamental question about the ecology of herbivore populations pertains to the relative influence of biotic and abiotic processes on nutritional condition. Nutritional condition is influenced in important, yet poorly understood, ways by plant secondary metabolites (PSMs) which can adversely affect a herbivore’s physiology and energetics. Here we assess the relative influence of various abiotic (weather) and biotic (intraspecific competition, predation risk and diet composition) factors on indicators of nutritional condition and the energetic costs of detoxifying PSMs for the moose population in Isle Royale National Park (U.S.A.). Specifically, we observed interannual variation in the ratio of urea nitrogen to …

Early Deprivation Alters Structural Brain Development From Middle Childhood To Adolescence, Margaret A. Sheridan, Cora E. Mukerji, Mark Wade, Kathryn L. Humphreys, Kathryn Garrisi, Srishti Goel, Kinjal Patel, Nathan A. Fox, Charles H. Zeanah, Charles A. Nelson, Katie A. Mclaughlin

Psychology Faculty Research and Scholarship

Hypotheses concerning the biologic embedding of early adversity via developmental neuroplasticity mechanisms have been proposed on the basis of experimental studies in animals. However, no studies have demonstrated a causal link between early adversity and neural development in humans. Here, we present evidence from a randomized controlled trial linking psychosocial deprivation in early childhood to changes in cortical development from childhood to adolescence using longitudinal data from the Bucharest Early Intervention Project. Changes in cortical structure due to randomization to foster care were most pronounced in the lateral and medial prefrontal cortex and in white matter tracts connecting the prefrontal …

Sex Differences In Cognitive Flexibility Are Driven By The Estrous Cycle And Stress-Dependent, Andrew T. Gargiulo, Jiayin Hu, Isabella C. Ravaglia, Annie Hawks, Xinyue Li, Katherine Sweasy, Laura A. Grafe

Psychology Faculty Research and Scholarship

Stress is associated with psychiatric disorders such as post-traumatic stress disorder, major depressive disorder, anxiety disorders, and panic disorders. Women are more likely to be diagnosed with these stress-related psychiatric disorders than men. A key phenotype in stress-related psychiatric disorders is impairment in cognitive flexibility, which is the ability to develop new strategies to respond to different patterns in the environment. Because gonadal hormones can contribute to sex differences in response to stress, it is important to consider where females are in their cycle when exposed to stress and cognitive flexibility testing. Moreover, identifying neural correlates involved in cognitive flexibility …
