  Experimental Validation of Low Temperature Viscosity Predictions for Sustainable Aviation Fuel Blends

  Franchesca Rose Hauck

  With the rise of focus and funding in sustainable initiatives, the transportation sector has identified Sustainable Aviation Fuels (SAFs) as a response to reduce carbon dioxide and other greenhouse gas outputs into the atmosphere. Before SAFs can be used by airlines, they have to pass an approval process to make sure fuels operate within industry standards. The approval processes is very time and material expensive. To lower overall costs to this process, a pre-screening process has been developed to predict physical and chemical properties of the prospective fuels. Viscosity has been identified as one of the key properties as it lends itself to is ignition probability prediction.The focus of this study is to validate different viscosity extrapolation and blending models at low temperatures. The blends tested are ternary blends of current fuels and key molecules found within approved SAFs. Four different sets of blends were tested to see how other physical or chemical properties affect the viscosity when blended and measured at -40°C and -20°C. Of the six models tested, the Arrhenius Blending Model results in the least amount of error compared to experimental values. As molecules were introduced into the blend sets, errors increased. Overall low error suggests the utility of this blend model in property prediction. To further lower error, future work can investigate the effects of molecular size and interactions within blends.

  Explainable Deep Learning for Construction Site Safety

  Ishan Vijay Ghutake

  The construction industry is going through a huge shift toward automation, with safety being one of the major challenges. We always want to take measures through which more accidents resulting serious injuries and deaths could be avoided. Indeed the construction sites are bound with several safety rules, one of the most important is having required personal protective equipment (PPE) based on the worker working environment. The presence of the monitoring camera at construction site provides an opportunity to enforce these safety rules by applying computer vision techniques and algorithms. This study shows capability of the Deep Learning model to classify worker as safe and unsafe and provides logical explanation to strengthen the prediction result. Here we exemplified classification of worker by using five convolutional neural network models with various layer structures. We collect a dataset of construction site scenes and annotate each image scene as safe and unsafe according to the workers working environment. The state-of-the-art neural networks successfully perform the binary classification with up to 90% accuracy. Furthermore, feature visualizations, such as Guided Back Propagation, Grad-CAM and different variants of LRP which is successful in showing which pixel in the original image contribute to the diagnosis and to what extent.

  Exploration of Correlations in Fitness and Injury Screening Clinic

  Luke Kelly Knapke, Julianna D. Leonard, Will Stephen Majercak, Abigail R. Shahady, Ciara Ann White

  The Department of Health and Sport Science has recently piloted a Nutrition, Fitness, and Injury Screening clinic to provide an experiential-learning opportunity for our student practitioners as well as important health-related data to the campus community. Within this program, clients are able to complete one or more of the following: nutritional consultations, health and skill related fitness testing, and injury screening. Here, we examine a variety of potential relationships between the numerous assessments that were performed. Specifically, we have explored questions both within each aspect of the clinic and several cross-disciplinary queries. Within the fitness testing protocols, we compared the multiple body composition and resting energy expenditure estimations and measurements that were made. Within the injury screening task, we assessed multiple measures of lower body coordination. With an interest in understanding how fitness measures may relate to and/or predict injury-risk, we also examined the relationship between: 1) balance and body composition; and, 2) lower body power and high-risk lower body coordination patterns. Our combined oral presentation will highlight our procedures and findings, as well as potential future investigations we are interested in pursuing.

  Exploring Dynamic Viscosity with Self-Assembly Systems Outside of Equilibrium

  Andrew Peter Lingafelter, Jack Brian Mclean

  All fluids have a characteristic viscosity and fluids commonly studied exist in an equilibrium state. However, some exist outside of equilibrium. These fluids are known as non-Newtonian fluids. Non-Newtonian fluids have a dynamic viscosity, which means that the coefficient of viscosity is dependent on the pressure of the system as well as temperature. Systems that have the ability to self-assemble from surfactant molecules also can express this dynamic viscosity, and achieve a state outside of equilibrium. The making and characteristics of such a system were explored. Copious amounts of energy are wasted in the form of heat ejected into the atmosphere from general to industrial processes. Future applications of self-assembly systems could include harnessing and reutilizing this wasted energy.

  Exploring the Effects of the COVID-19 Pandemic on Asian and Asian-American Students at the University of Dayton

  Michaela Catherine Kenney

  The overall purpose of this research was to examine the effects of the COVID-19 pandemic on Asian and Asian American students at the University of Dayton, particularly in regards to racist language surrounding the pandemic. The Asian population is often overlooked in terms of studying racism and prejudice, and since the beginning of the pandemic, hate crimes and reports of discrimination have never been higher. In order to study this at UD, a survey with questions regarding their experience during the pandemic was used with convenience sampling, including participants from various Asian American organizations on campus. Additionally, follow-up interviews were conducted to go more in depth on participants’ experiences regarding prejudice and discrimination. Out of 10 survey respondents, half of the participants reported facing some form of prejudice from other students because of their race or ethnicity as a result of the pandemic. Additionally, 60% of the participants reported facing some form of prejudice from the general public because of their race or ethnicity as a result of the pandemic. 90% of the respondents also reported an increase in stress or anxiety as a result of the pandemic. Although this study draws from a small sample, the implications for this research requires attention to the Asian and Asian American community as hate crime and reports of discrimination continue to climb.

  Exploring the Relationship Between Parental Warmth and Delinquency Among Youthful Offenders

  Sean Joseph Stull

  The focus of the current paper is to examine the link between parental warmth and delinquency. The specific focus was looking at how both parents’ parental warmth levels impact the adolescents in the study in relation to aggressive crimes. The research question for this paper is, "How does the level of parental warmth from both parents contribute to the possibility of the child becoming aggressively delinquent?” Research was done first to see what past studies and data was found on the subject. Some of the research done was finding out the definition of parental warmth and similar experiments done, all of which will be covered in the paper. The Pathway to Desistance data was used to test the aforementioned research question. The Pathways to Desistance is, a study conducted in Pennsylvania and Arizona that examined 1,354 serious juvenile offenders to assess the factors and experiences linked to their desistance from delinquency as they age out of adolescence. The sample is 86.4% males, 14.6% females, 20.2% white, 41.4% black, 33.5% Hispanic, and 4.5% Other. The educational level of the sample was 87.9% of the juveniles are either in school or skipped the question while 12% dropped out. Results from the study determined there is no correlation between parental warmth and aggressive offending, but the mother variable was close to correlation and could have correlation in other future studies. The policy implication will be discussed in the symposium.

  Fantasies of TikTok: The Limits of Social Media and Holocaust Advocacy

  Katharine Louise Schreyer

  Over the past decade, Holocaust scholars and museum professionals have debated the value of social media for teaching and commemorating the Shoah. Whether user-generated or created by institutions, native social media content is marginal in at least two senses. First, such content circulates outside the academic and professional venues in which Holocaust history and pedagogy are traditionally discussed. Second, such content is highly ephemeral - subject to sudden removal or alteration by creators or platform-owners.This paper advances these debates by analyzing a recent, and controversial, form of social media engagement with the Shoah: user-generated videos circulated on TikTok. Since TikTok is a fairly new platform populated mostly by young people, it is not seen as a venue for serious education or outreach. News of user-generated videos purporting to take the perspective of Holocaust victims, survivors, or witnesses sparked public outrage and spurred swift removal in the fall of 2020, demonstrating just how marginal such content is. However, the lines between such point-of-view (POV) videos and the multi-modal educational experiences offered by Holocaust museums or sites of destruction are not entirely clear. The first aim of this paper is to identify what features these practices have in common and consider which are distinctive - and distinctively worrying about - TikTok. The second aim of the paper is to ask what legitimate uses TikTok videos might have for increasing public awareness of the Holocaust and aiding human rights advocacy. A comparison between inherently short-form TikTok videos and longer-format digital content (such as podcasts or audio-visual testimonies) shows that TikTok is not an appropriate venue for crafting oral histories or recording the testimony of survivors. But TikTok’s heavy reliance on montage, capabilities for layering text and visuals, and proprietary modes for “stitching” content from multiple users offer potentially valuable resources for advocacy campaigns.

  Far Out Flower Child: Psychedelic Tourism and the Hippy Invasion of Latin America

  Adam M. Graber

  During the 1960s, the Hippy movement created an environment that allowed a new kind of tourism to thrive. Tourism to Latin America, primarily Mexico specifically, increased during 1960s and 70s as a result of the psychedelic renaissance. The tourism in question here would become known as psychedelic tourism. This provoked Mexico into deporting and demonizing those tourists and creating a new kind of tourism whilst also significantly impacting those rituals and native peoples that partook in highly secret psychedelic rituals that have existed for thousands of years.

  Financial Discrimination in Bangladesh

  Sydni Dionna Kidd, Elenore L. Stebbins

  Based on the work and data gathered by Counterpart International, a development agency funded by USAID, this presentation examines how financial discrimination in Bangladesh impact gender equality. This is part of a larger program Counterpart International has implemented since 2018, titled, ‘Promoting Advocacy and Rights’ (PAR) in collaboration with local non-government organizations (NGOs). Anchored in the Gender/Women in Development (GID/WID) approach, PAR aims to deepen democratic values within civil society to improve public governance. Financial discriminations are economic factors based on race, gender, economic status, and amount of investment in an area or region. In Bangladesh, rural women have been the most affected by financial discrimination from NGOs and the banks. Several factors are in play when someone experiences discrimination. Counterpart International has done significant work and research for the Bangladeshi people and in fact Bangladesh is also a signatory of major human rights conventions including the International Covenant on Civil and Political Rights (ICCPR); International Covenant on Economic, Social, and Cultural Rights (ICESCR) and International Convention on the Elimination of All Forms of Racial Discrimination (ICERD). These three particular United Nations treaties help protect citizens from discrimination and crime committed against them by their own country. Counterpart has created different evaluations and reward systems that help monitor this financial discrimination through programs such as Reporting Total Compensation of Recipient Executives, Electronic Payments System, Salary Supplement Guidance and more.

  Finding the Way: Identifying the Fine Line between Indoctrination and Education through the Sentiments of Students, Faculty, and Staff at Two Catholic Universities

  Tahreem Fayiz

  When students are in the college search process, they look to many different resources to help them find the best fit, and for some, that includes prioritizing the campus’ faith traditions. For students who prioritize their Catholic faith, the seek to find a campus that fulfill that promise of cultivating the person to live life following the way of Christ and His teachings. Students, however, are not the only ones who become community members at Catholic institutions. Faculty and staff may also consider the faith identity of an institution when seeking employment to find what is best for themselves. In this research, students, faculty, and staff members across two institutions were interviewed in order to understand how the perceive the Catholic identity of their institutions. The findings from this study will contribute towards gaining a better understanding of Catholic identity at nominally Catholic higher education institutions. This study will likely encourage more discussion among various Catholic higher education actors.

  First-Year Student Engagement in Campus Activities Programs During COVID-19

  Jairad Strait Hydrick

  Existing research highlights the relationship between student engagement and student success and persistence; however, this relationship is predicated on the ability of students to freely engage with one another, which has not been the case during the COVID-19 pandemic. Colleges and universities and their campus activities programs have transitioned to offering virtual, hybrid, and in-person programs that limit peer-to-peer and peer-to-staff interaction, so as mitigate health and safety risks. These restrictions contradict what has been long understood to be “best practice.” In response, this study sought to understand (1) how first-year students are engaging, or not engaging, with campus activities programs; (2) how COVID-19 impacted students’ decision to engage and not engage; and (3) the impact on desired student engagement outcomes. Using a survey design, first-year students at private, Catholic institution in the Midwest were surveyed regarding their attitudes and experiences with COVID-19, engagement with campus activities programs, and achievement of desired outcomes. Results demonstrate that while students continued to engage in various campus activities programs, and felt safe doing so, COVID-19 impacted students’ decision how to engage. Additionally, most participants felt disconnected from their peers, more concerned for their mental health, and a decreased sense of belonging. This study has implications for understanding the needs of the first-year students, who are most vulnerable to attrition, whose transition has been significantly disrupted by COVID-19, as well as emerging scholarship on engaging students across multiple modalities.

  Flexibility, Creativity, and Adaptability in the Sunshine State: A Local Study of Nonprofit Organizations During the COVID-19 Pandemic

  Lauren Elizabeth Tobal

  Nonprofit organizations are integral parts of communities across the world and often serve as safety nets for vulnerable populations. From healthcare to housing, nonprofits have the ability to make tremendous differences in people’s lives. This research, examined through the lens of civil society, helps to understand the ways in which nonprofit organizations contribute to society in unprecedented times. This study examines the effects of the COVID-19 pandemic on nonprofit organizations through in-depth interviews with leaders of four local nonprofits in Naples, FL. The organizations interviewed vary by the services they provide, but each support at-risk populations in a variety of ways. Participants were chosen based on convenience sampling and recommendations from other interviewees. Results from this research show increases in the number of individuals and families the nonprofits served, increases in the amount of collaboration between local nonprofit organizations, as well as some interesting positives that arose from the COVID-19 pandemic. From these findings, I conclude that nonprofit organizations are an integral part of supporting local communities, especially in times of crisis.

  Frequently Used Nutritional Strategies for Muscle Recovery in Active College Students

  Richard E. Holzheimer, Angelina Mae Loriso, Keiran Dolan Marvin, Makenna Delaney Ramsey

  The use of different supplements to aid in recovery is widespread throughout the physically active collegiate population. While it is evident that collegiate athletes and active individuals often use various supplements to aid in recovery, it is still unclear what supplements are being used most often and are perceived as most beneficial. The purpose of this study is to look at the most common nutritional recovery strategies being used by collegiate athletes and active individuals. This research will be conducted using a cross-sectional study survey design. The participants of this study are University of Dayton students, ages 18-23, that participate in any of the division 1, club, or intramural sports, as well as individuals that exercise at least 3 times a week. In order to collect and measure data, a survey will be disseminated to UD athletes and active individuals to assess their current supplement intake in regard to recovery. The data will then be further examined using both a descriptive and chi-squared analysis to examine recovery to reasoning and recovery to effectiveness. Results will be presented during the presentation.

  From Ballers To Bosses: How Sports Can Change Lives For Youth

  Nicole E. Rabas

  Sports are important to many families and children. They help kids stay physically active, develop cognitively, showcase teamwork and leadership skills. These skills relate to how these children interact with schools. They have positive and negative experiences with coaches and new experiences just like they do in classrooms. Through this research, the connection is made between the impact of sports on youth development, their experiences in school, and the best way teachers can handle this information.

  From Prop to Partner: the Evolution of Female Roles in American Opera

  Mariah Joanna Berryman

  For many years, women in opera have been in service to their plots. They have always been present, but have either been relegated to passive roles in their own stories or actively considered societal outcasts. They were dramatically stereotyped as either air-heads or witches, mothers or daughters, love interests or foes to be conquered. And, along with the character stereotypes came typically associated vocal stereotypes. Lighter and higher voices were assigned to roles that portrayed virtue, innocence, and other general characteristics of the “feminine ideal.” Conversely, lower voices were assigned to sinful, outcast, “fallen women.” These vocal stereotypes are especially prevalent for the women condemned to the fringes of society, the othered “them” in contrast to the idealized “us.” Examination of opera plots in contrast to historical documents and artifacts through time reveals an important movement towards more accurate dramatic and musical characterization of women in American opera.

  Gender, Mental Health, and Substance Use

  Emma Finch

  This study aimed to explore the connections between gender, age, mental health, and substance use. Data from 18,294 respondents between the ages of 12 to 17 from the 2004 National Household Survey on Drug Use were asked about their mental health and substance use. According to the results of the study, the older a respondent is the more likely they are to have higher scores on the depression scale which leads to a higher use of substances. However, after further testing, this model only explained about 5% of the variation in substance use. These results suggest that there may be other variables affecting substance use among teenagers. Further research beyond this study is necessary.

  Genetic interaction between the axial patterning gene, dve, and Dpp signaling in the developing Drosophila eye

  Anuradha Chimata Venkatakrishnan, Neha Gogia, Katie Marie Perry, Akanksha Raj

  An interesting question in developmental biology is how any three-dimensional organ develops from a single monolayer of cells. In multicellular organisms, delineation of Antero-Posterior (AP), Dorso-Ventral (DV), and Proximo-Distal (PD) axes are crucial for organ development. Drosophila melanogaster is an ideal model organism as the genes and pathways are highly conserved between Drosophila and humans. During eye development, DV axis formation marks the first lineage restriction event, and deviation in this process results in birth defects in the eye. Previously, we identified defective proventriculus (dve) as a new dorsal eye fate selector or patterning gene. dve regulates eye development by regulating wg, a negative regulator of eye development. Apart from wg, there are several other morphogens which havean important role during eye growth and development. Dpp signaling is one such pathway important for retinal differentiation. We hypothesize that dve, a transcription factor, regulates the Decapentaplegic (Dpp) signaling pathway, which is comparable to bone morphogenetic protein (BMP) signaling in mammals, during dorsal eye development. We will investigate the role of dve in the dorsal eye andwhether dve requires Dpp signaling to specify eye and head fate to form an organ of balanced size and shape. We utilized the GAL4-UAS system to modulate Dpp signaling in the dve domain. Thus far in our research, we have found that upregulation of Dpp in the dve expression domain results in an enlarged eye phenotype, while downregulation of Dpp in the dve domain results in a small eye phenotype. We havetested retinal determination genes to explore cell specific fate and further support the genetic interaction between dve and Dpp signaling. We are currently testing their interaction using clonal strategies to understand how dve regulates dpp in the developing eye. This study may have a significant bearing on growth, signaling and patterning defects and help in understanding the etiology behind genetic birth defects in the eye.

  Global Religion: Approaches to Climate Change and Sustainability

  Hannah Ellen Bean, Hannah Rose Kessler, Aaron D. Tilton

  We performed a literature analysis of research pertaining to how different religions approached climate change and sustainability. Our aim was to learn what different approaches, if any, world religions take to addressing climate change and sustainability. Learning what motivates action, or lack thereof, can help future leaders inspire their constituents to take positive action on climate change. We learned that different world religions have different approaches to sustainability, but usually have some sort of belief regarding environmental protection. Through our research, we learned that often, religious groups create climate action groups in order to put into action their beliefs about sustainability. The ways they approach this action is different, but climate action groups in general seem to be common amongst religious groups. Climate change is on the forefront of religious leaders' minds and there has been much more recent discussion about it and what actions we need to take than there has been in the past. As climate change becomes more of a pressing issue, it has become a focus of much religious teaching.

  Graphene Development for Removal of Bisphenol-S from Water

  Ismail Salem Alibrahim

  Bisphenol-A (BPA) and its analogues (BPs) are diphenylmethane derivatives with two hydroxyl groups on aromatic rings. About 3.5 million tons of BPA is produced annually for its usage in many applications such as a monomer primarily to synthesis polycarbonate plastic and epoxy resins and in the thermal receipt papers. BPs can be transported to water bodies through several routes such as degradable plastics, products manufactured with BPs, and after wastewater treatment. For example, the BPA levels in sewage sludge was found to measure between 0.5 and 5.1 mg/mL after wastewater treatment. BPs act as endocrine-disrupting chemical (EDC). United States Food and Drug Administration (FDA) banned the use of BPA in baby bottles in 2012. One feasible replacement of BPA is Bisphenol S (BPS). BPS, 4,4’-sulphonyl diphenol, was found to have a lesser impact on the endocrine activities and poses lower aquatic toxicity than BPA. Since the substitution of BPS for BPA in products and materials is a recent occurrence, there are still only a few studies investigating the impact of BPS on human health. However, some studies already suggested that BPS poses a human health and environmental contamination risk as well. Since concern has started to grow, methods of water treatment for BPs, such as adsorption processes, have been developed. This study investigated the performance Graphene oxide (GO) and reduced graphene oxide (rGO) to adsorb BPS from water at low concentration (~10 PPM). The GO synthesized by different methods (GO prepared by Hummer method and by newly developed method) shows a maximum percentage removal of BPS from water between 30% to 60%. On the other hand, reducing the GO by ascorbic acid increases the sorption capacity of the rGO to up to

  Graphic Design Summer Fellowship 2020

  Emily M. Cordonnier, Megan Marie Lewis

  A summer filled with uncertainty and social unrest, Megan Lewis and Emily Cordonnier researched methods of making and the creative processes. Lewis explored the intersection of form and design through clay. Using a wheel-throwing technique, she created pieces influenced by ceramic artists whose work balances at the intersection of fine art and design. Her final project was the culmination of the work she created over the tumultuous summer of 2020. Cordonnier’s research focused on paper-making techniques through experimentation and chance processes. The final book celebrates the outcomes of research and process utilizing found vinyl letters and handmade paper. Throughout their research and creative processes, both Lewis and Cordonnier researched and drew inspiration from a range of artists and designers that linked to their discipline of graphic design. In addition, research was recorded through weekly podcasts that served as a mode of dialogue about their summer research.

  Graphs and Groups

  Chloe M. Crabb

  This is a project from the course MTH 466, Graph Theory and Combinatorics. A graph is a mathematical object that consists of two sets, a set of vertices and a set of edges. An edge joins two vertices and depicts a relationship between those vertices. Two graphs are said to be isomorphic if their vertices can be relabeled and rearranged so that the graphs have the same structure. An automorphism is an isomorphism from a graph to itself. The set of automorphisms of a graph under composition forms a group. This project will explore graphs through a lens of group theory. It will examine automorphism groups of special classes of graphs.
