  Oklahoma SB 1470 and its Human Rights Implications

  Ryley Goles, Grace K. Hughes, Jacob E. Lunsford, Naumann

  Oklahoma’s Senate Bill 1470, titled the “Students’ Religious Belief Protection Act,” disproportionately silences students and employees in the Oklahoma public school system that are part of a religious minority. The bill states that Oklahoma public school employees cannot promote or teach ideas that contradict students’ religious beliefs. In addition, employees are subject to fines and/or termination for violating this bill. This legislation, if passed, would directly violate the Universal Declaration of Human Rights and the First Amendment by suppressing freedom of thought and speech. This bill comes as one of a number of bills across the country that aim to control what is taught in schools. This piece of legislation holds the potential to change what is taught in schools and how certain controversial topics may be portrayed – or even silenced. This bill could create a snowball effect that leads to more legislation further limiting educators and suppressing instruction on certain topics. Ultimately, it could result in states controlling what and how students learn about certain topics.

  Open-source Stereo Digital Image Correlation Optimized for Large Deformation Soft Materials Testing: Development and Validation

  Joseph G. Beckett

  Stereo digital image correlation (DIC) is an optical measurement technique capable of producing contour plots of 3D deformations. These rich measurement capabilities – namely, the ability to capture local shape and volume changes in specimens undergoing complex 3D deformations during mechanical testing – make DIC a compelling research tool for characterizing the mechanical properties of numerous classes of materials. Soft materials, which typically exhibit large strains at fracture, present several major challenges to DIC measurements including pattern breakdown, saturated image regions from glare, and large fields of view. In this research, a DIC system is designed to overcome these obstacles in a cost-effective manner using commercially available equipment and Digital Image Correlation Engine (DICe) open-source processing software. High-aspect-ratio image sensors, cross polarization, and custom DIC patterning stamps are utilized to improve DIC imaging quality for soft materials testing. The system’s extensive validation is discussed to demonstrate the system’s ability to yield repeatable and accurate data and to identify current limitations of the system.

  Opioid Epidemic Waves

  Chase Alexander Hoffman, David A. Somodi

  In 1999, Ohio saw only 327 overdose deaths. As of 2020, the number reported by the Ohio Department of Health was over 5000 deaths (Ohio University, 2021). The opioid epidemic can be traced in three significant “waves” as identified by the CDC: 1990s due to the over prescription of opioids, 2010 due to a rapid increase of overdoses involving heroin, 2013 due to the illicit production of fentanyl and its addition to heroin. As a result of the over prescription of opioids, new prescription laws in Ohio required physicians and pharmacies to log controlled substances into a database starting in 2006. Although there were new laws and regulations that were put in place, there was still rising cases of opioid overdoses. Additionally, there were significant cases of fentanyl being found in illicit drugs in lethal dosages. Currently, Fentanyl-related fatalities account for almost four out of five opioid overdose deaths (Georgetown Hospital 2021). Rehabilitation services are crucial to combatting addictive behaviors. During the pandemic, rehabilitation services addressing addiction were indefinitely suspended. As a result of this and other stresses that the pandemic placed on individuals and families, there was a significant rise in overdoses in Ohio (Perry, 2021). This poster explores the effect all these had on overdose deaths to determine which factors should receive the most attention.

  Optical Optimization for Pump-Probe Spectroscopy

  Jessica A. Jenick

  One important technique for materials characterization is that of pump-probe spectroscopy, which allows us to understand the interactions and characteristics of excited materials under light illumination. The goal of this project was to design and build a pump-probe optical setup for single shot spectroscopy of phase change materials. This setup requires that a sample be pumped by a blue laser to instigate thermal processes, and then probed by a white lamp to look for the spectral shifts as a function of time and optical power. Through the careful use of lenses and mirrors, we were able to refine our optical setup to get acceptable power levels and useful spot sizes to match a white light probe beam with a blue light pump. We have been able to overcome difficulties regarding the use of a white lamp with poor spatial coherence. Building on what has been learned through building this initial setup, we will be able to improve it over time. This setup can later be used with the spectrometer built by the physics department for the further experimentation.

  Optical Study of the Topological Semimetal Bi4Se3

  Margaret Brown

  Quantum confinement of the topological semimetal Bi4Se3 was observed as a giant enhancement of the optical bandgap in two characteristic length-reducing regimes: ultra-thin films and nanoplatelets. The films were prepared via DC magnetron sputtering and characterized using atomic force microscopy and ultraviolet-visible spectroscopy. Current work investigates correlations of reduced dimensionality to enhancements of the bandgap. By characterizing the dimensionality through microscopy, spectroscopy results can be mapped to changes in the band edge as determined through Tauc plots.

  Optimization Protection Coordination for Smart Microgrid

  Uchenna Nwaichi

  The increasing penetration of renewable energy resources into the power grid presents many challenges in terms of optimizing grid performance and ensuring effective operation. In the particular case of islanding microgrids, the coordination of microgrid protection schemes to provide adequate system protection during grid-connected fault conditions and to seamlessly accommodate the transition to islanded operation is of significant interest. Several recent studies have explored this problem characterizing the different fault regimes evident in islanded operation, and numerous approaches to resolving these challenges have been proposed ranging from adaptive protection methods, differential current methods, voltage droop and harmonic distortion approaches, and phasor-based and travelling wave methods. New approaches to this problem continue to be explored and some recent reports have demonstrated effective operation on model systems. In a robust microgrid with multiple sources, optimization of the microgrid protection scheme is necessary to avoid miscoordination due to the possibility of changes in microgrid load or power flow. In this work a smart approach of fault isolation and system protection using circuit segmentation is proposed. A mathematical model of the protection scheme is developed, and a coordinated protection system is designed with redundancies to ensure protection in the event of device failure. Optimization methods are explored where an objective function is minimized using, water cycle, particle swarm, genetic, simulated annealing and pattern search optimization algorithms. The design approach seeks to minimize the protection response time, minimizing the time from fault detection to system segmentation and isolation. A comparative assessment of the overall performance of the listed optimization approaches is presented based on performance metrics such as operating time and solution convergence.

  Our Lady of Pellevoisin

  Jacqueline Rose Kasner

  Estelle Faguette was a French servant who was in the hospital dying of tuberculosis when she saw Mary appear to her, rebuking a demon. Mary would continue to visit Estelle for five days, eventually curing Estelle from the disease. After Estelle was cured, Mary would continue to visit her ten more times before her death in 1929. Estelle's faithfulness has allowed for a new Scapular of the Sacred Heart, and shrines of Our Lady of Pellevoisin in New York, NY and McIntosh, Ont, indicating the apparition has an impact not just in the small village of Pellevoisin, France, but also around the world as well.

  Permeability measurement of 3D-printed controlled-porosity deltoid inserts for composite T-joints

  Khalid Aldhahri

  Liquid Composite Molding (LCM) processes are one of the most common ways to produce composite material structures for various high-performance industries, especially for aerospace applications. LCM processes include resin transfer molding (RTM) and vacuum assisted RTM (VARTM). A key challenge with the LCM process is how to fully impregnate the dry fiber preform with resin inside the mold. Limited research has been conducted to investigate the resin flow behavior in critical regions of complex geometry, such as the junction between the flange and web in T-joints (referred to as a deltoid). This area is very important to the structural integrity and long-term durability of the T-joint, yet it is often ignored, leading to a resin-rich area. This study describes initial work aimed at producing custom-designed deltoid inserts with controlled porosity using additive manufacturing. Two different porosity geometries were developed, and deltoid shapes were produced with each one. The density for each porosity type was parametrically varied from 30%–70% solid (infill density). This presentation will present and discuss the permeability measurements made for each one in the three principal directions (K1, K2, K3). The 3D printed insert will have a porosity that can optimize resin flow, while simultaneously providing perfect geometric support for the plies of fabric that come together in this region.

  Physiological and morphological profiles vary with seasonal and cold acclimation in the freeze tolerant Cope’s gray treefrog Dryophytes chrysoscelis

  Chase Jennings, Andrew Joseph Morosky, Elizabeth Evans Yokum

  Dryophytes chrysoscelis possess several physiological mechanisms that contribute to their ability to be freeze tolerant which is a strategy that utilizes cryoprotectants to combat the osmotic forces that damage the cellular structure of organisms during freezing. This mechanism allows D. chrysoscelis to survive multiple cycles of freezing and thawing over the winter months. To study physiological changes induced by seasonal and cold acclimation periods, heart rate, feeding behavior, body mass, and dorsal coloration were evaluated in a laboratory setting using a protocol designed to mimic the natural reduction in temperature seen in nature. Wild-caught males were evaluated following capture in the summer and throughout the fall and winter seasons at varied temperatures and dates: August at 22°C (lab acclimated), October at 22°C (seasonal acclimated), December at 5°C and 22°C (cold acclimated and control), and January at 22°C (deacclimated). It is hypothesized that cold acclimated frogs would differ from warm acclimated frogs held at constant temperature in heart rate, body mass, feeding behavior, and dorsal coloration. Results show unique profiles at each experimental date and temperature, supporting the hypothesis that cold acclimation has a physiological impact on the measured variables. These findings also suggest that there are other, internal, mechanisms in place that contribute to the seasonal and cold acclimation response seen in D. chrysoscelis beyond the previously hypothesized temperature changes. These findings have broad implications regarding how the physiological mechanisms are regulated in organisms that exhibit freeze tolerance strategies. Our findings also contribute to the field of cryobiology, and its utilization in the field of science and medicine.

  Police Investigators' Perceptions of Victim Involvement During the Investigation Process

  Kaylin G. Florentino

  Law enforcement officers handle various crimes and cases, many of which involve working with victims. However, most studies have focused on the perspective of the victim, their trauma, and the role they play within the investigation. The scarcity of research focusing on police perception of the victim’s involvement within the investigation process is important because few studies have been done. The current study used phenomenological approach to explore the perceptions of the police investigator about the victims’ role in the investigation process. Through snowball sampling, three police detectives from a Midwestern police agency volunteered for a semi-structured interview. The interviews were conducted via zoom and lasted an average of one hour and thirteen minutes. The interviews were transcribed verbatim, while simultaneously writing memos and thematic analysis was conducted. Preliminary findings indicate that police investigators encourage involvement from domestic violence and sex crime victims, whereas property crime victims are not seen as needed for the process. Detectives are looking for cooperation when appropriate and asked of the victim. Additionally, there were no explicit responses or implications that suggested victims of any kind should not have any involvement within the investigative process.

  Political Polarization and its Effect on Political Participation

  Sean Matthew Feikes

  In recent years, perceived political division has risen in the United States at an astonishing rate. With the rise of social media in the last decade or so, political opinions and ideologies are able to reach more and more people than ever before. With this mass distribution of thoughts and ideas, political opinions are stronger and more divisive causing more polarization among citizens. The purpose of this research is to examine how political polarization affects political participation among college students. The method of analysis for this research question is a survey administered to UD students and distributed via email. The brief survey contains questions regarding their political identity and ideology, opinions on the current state of politics, and stance on some highly political topics. Results from the anonymous survey are contextualized within the existing literature.

  Postpartum Depression: Its Impact and Tools for Diagnosis

  Madyson Alexis Maynard, Natalie R. Piraino

  According to data gathered in 2021, postpartum depression (PPD) is one of the most common complications that affects 10-15% of mothers worldwide (Amit, 2021). It is a leading cause of maternal perinatal mortality, accounting for about 20% of postpartum deaths (Amit, 2021). Postpartum depression is simply depression that occurs after childbirth. Symptoms include, but are not limited to, depressed mood or severe mood swings, insomnia, loss of appetite, intense irritability, and difficulty bonding with the baby (Mayo Clinic, 2018). If left untreated symptoms may worsen to severe anxiety, panic attacks, thoughts of harming yourself or your baby, and recurrent thoughts of death or suicide (Mayo Clinic, 2018). We found tools used to measure and diagnose PPD but are curious to seek why PPD remains a significant problem. The MGH Center for Women’s Mental Health mentions that the Edinburgh Postnatal Depression Scale (EPDS) is most commonly used (Nonacs, 2008). Another tool currently being used is an online resource through Mental Health America titled “Depression Test for New and Expecting Parents.” The use of current tools helps women recognize the symptoms of PPD and helps improve the diagnosis of PPD in patients and yet “only 50% of women with prominent symptoms are diagnosed with PPD,” (El-Hachem, Charline, et al., 2014). The purpose of this poster is to learn more about PPD, how it is currently being diagnosed, and to suggest alternative ways to increase new mothers’ awareness of PPD that could lead to better diagnosis and treatment.

  Predicting Fading in Free Space Communication Channel Using Deep Learning

  Mohammad Albaqer Hammid Jwaid Al Ghezi

  Free space optical communication plays a role in daily communications and has the advantage that it does not need a huge infrastructure of cables. Due to that advantage it can be used to deliver the internet to urban as well as remote locations, in the communication with drones, etc. However, the optical signal propagating through the atmosphere gets distorted due to fluctuations in weather parameters such as temperature and wind speed, resulting in optical turbulence, which impacts the strength of the optical signal that is received. In our work, we will use a deep learning algorithm to predict when these distortions could happen based on optical turbulence and weather data. Deep learning algorithms will be trained on the weather data as an input and the intensity of the signal as an output. Knowing the potential fading in the signal can help us to prevent losing the connection with the receiver. For instance, if we control a drone with an optical communication channel then it is important to know the potential fading in the signal, since this can be helpful for the controller to take action to prevent losing the connection with the drone.

  Preparing Collegiate EMS to be First Responders for Mental Health Emergencies

  Maggie M. Garcia, Hannah Jayne Lindenman

  University of Dayton Emergency Medical Services (UD EMS) is a student-run collegiate EMS organization comprised of around 60 full-time undergraduate students who volunteer to provide 24/7 prehospital care to their campus community as nationally and Ohio certified Emergency Medical Technicians. In January 2022, UD EMS experienced its highest volume of mental health-related calls in the organization’s history. Additionally, according to Riaz et. al, (2021), with the rapid expansion of collegiate EMS programs, there remains “a lack of research and evidence-based guidelines surrounding how we, [in collegiate ems] can best serve college students in need of behavioral health services.” With the increased incidence of mental health emergencies in our own campus community and in collegiate EMS as a whole, we will be exploring the prevalence of these behavioral health calls and summarize current research on how to improve protocols for responding to mental health calls. The purpose of this poster is to present these findings and recommendations related to improving current protocols for responding to mental health emergencies within collegiate EMS.

  Probability Analysis of the Relationship Between Share Price and ESG Ratings in the Aerospace & Defense Industry

  John Richard Coffey

  ESG is an evolving niche in the financial markets, as investors attempt to identify the companies that best fit with their own values. Aerospace and Defense firms are under constant scrutiny for their involvement in global warfare and contributions to the airline industry, one of the most fuel-intensive industries outside of Oil and Gas. The objective of this research is to determine which metrics within ESG impact share prices for the Aerospace and Defense industry most and build a probability model to measure the potential impact ESG has on share price movement. ESG scores for individual metrics such as Air Quality and Energy Management in Environmental and Customer Welfare and Data Security in Social. Regressions were then run with the scores for each ESG metrics run against a firm’s share price to measure correlation. Correlation was generally weak across most metrics; metrics with above 50% correlation were chosen to develop the probability model. Highest correlation was found among Social metrics, likely explained by the social impact defense companies have on war torn countries. The correlations were used to build a conditional joint probability model that determined the likelihood that a change in share price was caused by changes in one of the key ESG scores. A probability was determined, however low correlations brought into question the accuracy of the model.

  Professional Development in Summer Camp Employment

  Kari Truax

  Many college students seek out internships and employment over the summer to grow professionally and personally. Students who choose to work as summer camp counselors are gaining transferable skills and are in environments where they can develop (Tessman et al., 2012). There are nearly 14,000 camps across the United States and majority of the camp counselors working at these camps are college students (Schelbe et. al 2018). With this seasonal work being such a demand and a common summer job for college students, it is important to consider the role that a supervisor plays in the development of their counselors. The purpose of this study is to identify what experiences are being provided by summer camps to aid student development and how supervisors are incorporating professional development throughout the summer. Data for this qualitative study emerges from 10 camp supervisors across the United States and Canada. The data collected has shown college students who spend their summers working at camps have a deep understanding of who they are, what strengths they have and how to apply skills learned to other jobs and environments. Supervisors concluded that summer camp jobs offer students an opportunity to grow in leadership, communication, decision making and critical thinking. The findings of this study not only can inform camp supervisors of the professional development opportunities provided to college students at varying camps, but also can inform higher education professionals of a field that provides students with a meaningful and impactful summer experience.
