Agency Actualization And Artistic Awakening: The Poetic Rhetoric Of Freedom School Students, Eden Doyle

Butler Journal of Undergraduate Research

This paper analyzes the rhetoric of poems written by Freedom School students in Mississippi amidst the Civil Rights Movement of the 1960s. Much of the rhetoric documented, explored, and valued from this era is of adults with the power and means to have their voices heard and respected; however, this paper argues the value of these students’ unique Black experience as one that is underexplored and greatly compelling. The social and political context surrounding the inception of Freedom Schools is discussed, as well as the need for further research and scholarship on the intellectual activity and rhetorical artifacts of the …

The Effects Of Covid-19-Induced Stress, Anxiety, And Depression On The Eating Behavior Of College Women, Natalie Simpson

Butler Journal of Undergraduate Research

Increases in the prevalence of disordered eating patterns have been linked to distress and poor mental well-being. Additionally, COVID-19 has been linked to both depressive and anxious symptomatology, along with increased feelings of distress (Fitzpatrick et al., 2020). Because disordered eating is particularly prevalent among college-age women, this study sought to determine how depression, anxiety, and stress affect eating behaviors of college women in the context of the COVID-19 pandemic. One hundred seventy-nine women, aged 18–24, at Butler University gave informed consent before completing a questionnaire pertaining to their demographics, their stress surrounding COVID, and their weight change since March …

An Evaluation Of Women’S Social Status In Colonial Hong Kong With A Feminist Lens - Case Studies, Heng Du

Butler Journal of Undergraduate Research

Even though Hong Kong remained under British control from 1842 to 1997, denizens were not modernized in a way comparable to that of the British. To the contrary, while governing Hong Kong, British colonizers allowed continued reference to ancient Chinese customs in the area. Such policy diminished women’s chances of receiving fair treatment in matters such as property management and divorce. Unlike in Hong Kong, women were legislated to be parallel to men in matrimonial and property inheritance petitions in China, Britain, and colonial Singapore. This study is based on two exemplary cases judged by authorities in colonial Hong Kong. …

Current research provides significant data indicating worsening mental health and substance use. This paper looks at how applicable those trends are to a small private university in Indianapolis, Indiana. The data included 261 respondents composed of students, faculty, and staff of the university. The results reveal that college students, faculty, and staff experienced statistically significant increases in feelings of unhappiness, depression, loneliness, hopelessness, agitation, and irritability during the pandemic compared to before the pandemic. Data analysis of …

Identifying Disinformation In Scholarly Publishing, Natalie M. Mclendon

Butler Journal of Undergraduate Research

This paper examines the pro-Confederacy movement’s attempt to distort history through textbook revision to argue in favor of strengthened media literacy as a brace against the effects of disinformation and propaganda. Previous definitions of misinformation and disinformation overlap and are as yet unclear and, therefore, should be further studied. “Lost Cause” mythologists worked diligently to propagate school textbooks which portrayed skewed versions of history that cast Southern Confederates’ cause as noble and honorable while obscuring the real reason for the Civil War. While undergraduate students can rely on the CRAAP and BEAM methods of identifying problematic texts, they should be …

Water Erosion In The South-West Of Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

The averaged annual direct cost of water erosion to dryland farming in Western Australia is estimated to be $10 million, but the costs are much higher in years of severe summer storms.

Water erosion occurs when water flowing over the land surface moves soil particles downslope. Water erosion is a natural process, but is accelerated under agriculture, especially on cropped land. Water erosion causes loss of topsoil, reduced crop yields, damaged infrastructure, weed dispersal, eutrophication (algal blooms) and silting of dams and natural waterways.

Characterization Of Select Lysine Mutations Of The Cystine/Glutamate Transporter, System XC-, Anna Koppin, Claire Buck, Amanda Gibson

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

System xc- is a membrane transport system that plays a critical role in mitigating oxidative stress. As such, its regulation is critical for proper brain functioning. Recent work in our lab has shown that System xc- activity increases immediately during an oxidative insult by undergoing a change in localization to the plasma membrane, but we have yet to identify the specific mechanism for the redistribution of the transporter. Previous studies have demonstrated that post-translational modifications of proteins can lead to differential protein distribution within cells. Therefore, in this study, we sought to determine if post-translational modification (PTM) of the transporter …

Development Of A Novel Method For Identifying Antibiotic Producing Microbes From The Soil, Sean Slayton

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Multi-drug resistant (MDR) bacteria are strains of bacteria that are resistant to multiple types of antibiotics and pose a serious public health threat. Our research group has developed a novel way to rapidly screen soil bacteria isolates for antimicrobial chemical production in a clear and reproducible manner. We examined the effects of certain variables on our method including: 1) agar type on antimicrobial diffusion, 2) agar depth on antimicrobial diffusion, 3) age of the soil isolate on the amount of antimicrobial produced, and 4) soil isolate placement on the inhibition of bacterial growth. Our combined results led to the creation …

Effect Of Post-Warm-Up Transition Time On Anaerobic Performance In Female Collegiate Volleyball Players, Samantha Martino, Sophia Rosiek, Haleigh Cripe

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Post-warm-up transition time (PWTT) is the period of time between the end of a pre-game warm-up and the beginning of gameplay at a particular sporting event. During this period of time, typical pregame traditions are completed such as the playing of the National Anthem and recognition of players and coaches. This length of time can vary from sport to sport. Research shows that a dynamic warmup is encouraged to improve performance and decrease the risk of injury. Further, rest periods are necessary for optimal performance. Too short of a recovery time can result in muscle tissue damage, but too long …

Role Of Neuroinflammatory Response On Cell Proliferation Following Neurotoxic Lesioning In Zebrafish, Sarah Heinowski, Nathaniel Vorhees, Nathan Koorndyk, Helen Dodge

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Parkinson's Disease (PD), a neurodegenerative disorder characterized by dopaminergic neuronal loss and motor impairment, affects roughly 1 in 500 people. Interestingly, olfaction loss, the loss of smell, is prevalent in over 95% of those with PD. Zebrafish provide a unique model to study neurodegenerative diseases, including PD, as they possess the unique ability to regenerate neurons (i.e., neurogenesis) throughout their lifespan. Contrary to mammals in which inflammation often has negative associations with neural injury recovery, inflammatory response within zebrafish is thought to have a key role in this regenerative capability. Thus, we aimed to inhibit the inflammatory response and investigate …

Temporal Analysis Of Former High School Athletes’ Perceptions Of Fitness As They Enter College, Alec W. Kowalski, Sophia K. Rosiek, Adam H. Ibrahim

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Researchers suggest that physical activity promotion may be necessary to preserve former athletes' long-term health and transition out of sport in retirement. Exploratory research has revealed that the fitness perceptions (a known contributor to exercise behavior) of former high school athletes (FHSAs) who do not continue sports in college fluctuate over the course of their freshman year. To inform potential intervention efforts in this population, the purpose of this study was to explore why FHSAs' perceptions of fitness vary over their freshman year of college. Methods: Participants completed eight online surveys over their first year of college, within which they …

Does Phosphorylation On Serine 26 Of System Xc- Lead To Changes In Cell Surface Expression?, Katherine Lane

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

System x_c^- is involved in transporting cystine into cells and glutamate out of cells, and ultimately in production of the antioxidant glutathione. Antioxidants are important in protecting cells from oxidative stress which can occur when waste products like H₂O₂ build up in the cell. Previous studies have shown that a critical regulator mTORC regulates system xc- by phosphorylating serine 26 (S26) on the N-terminus of the cystine/glutamate antiporter xCT, leading to a reduction in transport activity. The specific objective of this study is to determine the mechanism by which phosphorylation of S26 affects activity. To …

Ammonia Inhalants Impact On Shot Put Throw Distance, Jaden Grigg, Cole Stalter, Jace Gerlach

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

A variety of ergogenic aids have been researched in the past to assess effects on athletic performance. One potential aid relatively unstudied is ammonia inhalants (AI’s), commonly referred to as smelling salts. AI’s have been found to enhance peak and mean power output (PPO/MPO) in anaerobic activities. Because shot put throws rely primarily on anaerobic power, there is the potential for AI’s to improve performance. This study was designed to determine whether an acute, one second inhalation of a commercially available AI immediately prior to a shot put throw would increase the total distance a college athlete shot putter (n=10) …

Neurodegeneration And Neuroinflammation In The Olfactory Bulb Of Zebrafish Following Acute Hypoxia, Skylar Dewitt, Evan Thomas

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Hypoxia, the lack of sufficient oxygen in tissues to sustain bodily functions, has a deleterious effect on physiological and behavioral health. Unlike mammalian brains, which are restrained in their capacity to recover following damage and hypoxic injury, zebrafish are an excellent model to study exposure to hypoxia due to substantial neuroplasticity mechanisms within their brain. Specifically, the olfactory bulbs (OBs) display high neuroplasticity and neurogenesis (i.e., generation of new neurons), making it a useful model to study neural responses under stressed environmental conditions such as hypoxia. Here, we establish a new paradigm of hypoxic exposure in zebrafish to uncover the …

Modeling Olfactory Dysfunction In Parkinson’S Disease In Zebrafish, Nathaniel Vorhees, Samantha Groenwold

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Parkinson's Disease (PD), a neurodegenerative disorder characterized by dopaminergic neuronal loss and motor impairment, affects roughly 1 in 500 people. Interestingly, olfaction loss is prevalent in over 95% of those with PD. However, the underlying mechanisms of PD and olfactory dysfunction are not well understood. Zebrafish provide an ideal model to study neurodegenerative diseases and regenerative processes as they present neurogenic capability (i.e., generation of new neurons) and a high degree of neuroplasticity. We developed a model to study the association between dopaminergic loss and olfactory dysfunction in zebrafish. To do this, we used adult zebrafish of both sexes and …

Expression Of Olfactory-Induced Anxiety Behaviors Following Hypoxia Treatment In Adult Zebrafish, Cassidy Larson, Luke Horsburgh, Cameron Houck, Skylar Dewitt

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Exposure to hypoxic conditions leads to neural loss of function or death in the nervous system of mammals. Zebrafish, given their sophisticated neuroregenerative abilities, are able to survive low-oxygen conditions with fewer consequences. These capabilities are crucial for the olfactory system of zebrafish, as their olfactory epithelium is directly exposed to damage and toxins in the environment. Given that olfaction allows for critical behaviors such as foraging, mating, predator detection, and non-visual perception of dead fish, possessing functional olfactory sensation is vital to survival. Cadaverine is a chemical compound that mimics putrescine, the scent of decaying flesh. This scent induces …

The Acute Effects Of Incorporating Lower Limb Foam Rolling Into A Dynamic Warm Up For Men’S Soccer Player Aerobic Endurance And Muscular Power Performance, Grace Wunderlich, Madeline Walter, Amelia Bont, Alyssa Hettel

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Warming up before exercise increases muscle metabolism and reduces the risk of injury. Soccer players are prone to lower limb injuries, therefore a warm up that reduces injury and improves performance is ideal. Foam rolling is known to reduce delayed onset muscle soreness, loosen muscle fascia, and promote blood flow to muscles when utilized post-exercise. As such, the inclusion of foam rolling in conjunction with a dynamic warm up prior to exercise may further reduce injury risk and optimize performance. However, current research has not examined the relationship between combining foam rolling with a dynamic warm up on exercise performance. …

Degeneration And Neurogenesis Following An Excitotoxic Focal Lesion To The Olfactory Bulb Of Zebrafish, Solange Fingleton, Alina Ciesielski

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Neurogenesis is the process of new neuron generation in the brain. Zebrafish have 16 different neurogenic sites, which allows for effective damage and lesion repair because of the ability to constitutively regenerate neurons. In zebrafish, the olfactory bulbs — part of the olfactory system – are highly regenerative and neurogenic. Our lab established a model of excitotoxic lesion (that targets glutamatergic neurons), and determined that the olfactory bulbs are structurally and functionally recovered. However, the processes of neurogenesis in the olfactory bulb following direct injury has not been studied. In this work, we use the same neurodegenerative model using an …

A Christian Framework For Competitive Sport, Owen Leibrock

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Christianity and competitive sport have a long history of interaction, oftentimes adversarial in nature. Yet in the last century and a half, Christians have embraced sport in such foundational ways that it is often now hard to imagine sport without certain Christian ideas and images. Competitive sport has taken on many forms and has been used in many ways both destructive and constructive. This wide range of Christian responses to sport throughout history begs the question: Does competitive sport truly fit within a framework of Christian ethics and values?

In order to answer this question, I will engage with theories …

Dopaminergic Synapse Loss In 6-Ohda Lesioned Zebrafish, Grace Stalions, Heather Van Dort, Gabriella Taylor

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Parkinson's disease is a neurodegenerative disorder caused by degeneration of dopaminergic neurons, and an early symptom of Parkinson's disease is olfactory dysfunction. A common animal model used in Parkinson's disease research is zebrafish because of their unique neuro-regenerative ability, which is particularly in their olfactory bulb. In order to create a model of the early stages of Parkinson's disease we injected zebrafish with the neurotoxin 6-hydroxydopamine (6-OHDA) to induce the degeneration of dopaminergic neurons in the olfactory bulb. Olfactory system recovery post 6-OHDA injection has been recorded in previous literature, but the state of synaptic dopaminergic synapses post-injection has not …

Temporal Qualitative Analysis Of Former High School Athletes’ Exercise Satisfaction During Their Freshman Year Of College, Sophia K. Rosiek, Alec W. Kowalski, Adam H. Ibrahim

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Research studying the exercise behavior of retired athletes has discovered that former athletes have a more difficult time transitioning to life after sports. This comes as a surprise, as it is expected that athletes not only understand the benefits of exercise but also desire to remain physically active. Following their last competition, former athletes may feel lost without their sport holding them accountable to regular exercise. The extent of these former athletes' exercise behavior is not completely understood. Therefore, the objective of this study is to perform a qualitative analysis of survey responses aimed at further comprehending exercise behavior among …

Effect Of Delaying Hca Exposure On The Development Of Manic/Depressive Behaviors In Sprague Dawley Rats, Eden Comer, Rachel Mast, Natalie Olander, Mackenzie Williams

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Bipolar disorder (BD) is a neuropsychological disorder that is characterized by cyclical periods of depressive and manic behaviors. The Chase lab is focused on developing a reliable animal model for BD in order to characterize the critical neurophysiological and neurochemical changes that trigger BD. Previous studies in the lab have shown that daily injection of rat pups from postnatal day 3 through 19 (P3-P19) with homocysteic acid (HCA) leads to the development of a mixed manic and depressive state after puberty. These behaviors can be reversed by treatment with lithium and involve changes in gene expression in the prefrontal cortex …

The Chronic Effects Of A Stretching Program On Range Of Motion And Velocity Output Of An Overhand Throw In Collegiate Baseball Players, Keaton Hamilton

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Current acute stretching programs have been reported to increase shoulder range of motion (ROM) utilizing the cross-body stretch and the sleeper stretch but have not examined how this increase could affect throwing velocity in overhead athletes. Few methods have been found to increase throwing velocity with the exception of various weighted ball and strength training programs, often associated with high rates of injury. The aim of this study was to determine if a nine week stretching protocol would result in improvements in shoulder ROM which may lead to an increase in overhand throwing velocity. It was hypothesized that a 9-week …

Creation Of An N-Terminal Xct Mutant Lacking Lysines For Use In Protein Turnover Studies, Alexandria Switzer

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

xCT plays a role in protecting cells from oxidative stress as well as intracellular glutathione synthesis. If this process is impeded, reactive oxygen species accumulate in the cell, leading to cellular damage, and if left unchecked, it can lead to neuronal loss. Ubiquitin is a small protein that some evidence suggests can negatively affect the stress response pathway modulated by xCT, as well as induce cell death. It is hypothesized that ubiquitin binds to xCT on the N-terminal lysine residues, and there are six conserved lysines in the N-terminal domain at positions K4R, K12R, K30R, K37R, K41R, and K43R. Previous …

In-Situ Characterization Of Jatigede Local Roid Banana (Musa Spp.) Based On Morphological And Agronomical Characteristics, Ade Ismail, Vika Faraditha Pratiwi, Haris Maulana, Ichsan Nurul Bari, Yani Maharani, Fajar Maulana Wijaya Kusumah

Jurnal Kultivasi

Banana (Musa spp.) is one of the agricultural commodities that’s widely cultivated and used by the local community. Currently, only 101 types of local varieties of bananas are registered in Indonesia; one of them is the Roid banana from Jatigede District. Roid bananas grow wild without any mandatory special care. Continuous use without any conservation and preservation efforts can lead to scarcity of Roid banana germplasm as a genetic resource. Therefore, it is necessary to identify the distribution and diversity of Roid bananas through in situ exploration and characterization activities. This study aimed to identify the potential for genetic diversity …

Impact Of Community-Driven Interventions On Dietary And Physical Activity Outcomes Among A Cohort Of Adults In A Rural Appalachian County In Eastern Kentucky, 2019–2022, Heather Norman-Burgdolf, Emily M. Dewitt, Rachel Gillespie, Kathryn Cardarelli, Stacey Slone, Alison Gustafson

Dietetics and Human Nutrition Faculty Publications

Several environmental level factors exacerbate poor health outcomes in rural populations in the United States, such as lack of access to healthy food and locations to be physically active, which support healthy choices at the individual level. Thus, utilizing innovative place-based approaches in rural locations is essential to improve health outcomes. Leveraging community assets, like Cooperative Extension, is a novel strategy for implementing community-driven interventions. This prospective cohort study (n = 152), recruited in 2019 and surveyed again in 2020 and 2021, examined individual level changes in diet and physical activity in one rural Appalachian county. During this time, multiple …
