Quantifying Cattle Movement through Identified Pastural Trails using Unmanned Aerial Vehicles
The purpose of this study is to quantify livestock in a pasture by identifying cattle trails using unmanned aerial vehicles (UAVs). The UAV was sent on a pre-programmed route, to collected one image per second, and obtained a total of 1,320 images. The orthomosaic constructed by images obtained from unmanned aerial vehicles were used to stitch, with a mean reprojection error of 0.229, the 95.5-hectare pasture from our study site. Our objectives are to 1) identify the characteristics distinguishing walking paths and grazing trails in relation to vegetation availability, 2) determine the density of the cattle trails and the proportion of heavily used trails and 3) interpret the data to develop the interconnected relationship between the disturbance of pastoral livestock and resource availability. The findings of our study will contribute additional research towards understanding the relationship between cattle mobility and resource availability. Identifying the relationship is needed in order to implement better land management techniques and biodiversity conservation of our agricultural landscapes.

The impact of exercise on blood metabolites and other health parameters during the reconditioning period of emaciated stock type horses
In the last decade there has been minimal research on the reconditioning aspect of emaciated horses that have gone through rehabilitation. The purpose of this study was to analyze how exercise affects the stress level of recovering emaciated horses during rehabilitation. This study was conducted from April to June 2023 at Sul Ross State University to evaluate the effects of progressive exercise on blood lactate, respiratory rates, heart rates, and body temperature. Data was collected during the last eight-week portion of a 20-week recovery study in which these horses were rescued, rehabilitated, and reconditioned. Measurements were taken at week 12, 16, and 20 pre and post exercise. Blood was drawn as well as lactate and health parameters were measured while the horses were resting and was repeated at 0, 5, and 15 minutes post-exercise. The exercise period progressed from 15 to 75 minutes on a Priefert walker during the study period as the horses conditioning increased. Ten horses were used for this project and were exercised five days a week with two days for rest each week. While data is still being analyzed, early results have indicated that horses were not stressed during the workouts based on recovery times and lactate levels.

Exploring Genotypes of Black and Brown Spotting in Dorper Sheep
Dorper sheep are a hair-type breed adapted to the heat and have two color phenotypes: a white body with a black head or a white body with a white head. However, there is variation in the amount of black found in Dorper sheep coats, indicating breeders can make genetic selection decisions on hair color to meet market demand. The purpose of this study was to identify mutations associated with colored spotting in Dorper sheep at Texas A&M University – Kingsville. We sampled 60 Dorper Sheep (55 females and 5 males) by recording 360-degree view photos of the sheep’s body to quantify the amount of black and brown spots. DNA was extracted from blood to be used in a candidate gene study. The candidate genes targeted included melanocortin one receptor (MC1R) and tyrosinase – related protein 1 signaling protein (TYRP1) using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) test. Gimp 2.0 software was used to quantify the amount of coat color. Out of the 60 sheep that were sampled, 22 have a full white coat, 17 have spots, 12 have specks, and 9 have brown spots. Genotyping analysis is currently underway.

Neuroscience
The Effect of Stress on Pavlovian Conditioning
The purpose of this study is to identify how a single stressful experience affects Pavlovian learning. Prior research demonstrates that a single exposure to stress produces a long-lasting increase in Pavlovian conditioned responding, and this increase involves the midbrain dopamine system. However, the stress-related signals mediating this increase remain unknown. Stress promotes the release of corticotropin-releasing factor (CRF) into the ventral tegmental area (VTA), a key dopamine-producing nucleus in the brain. Dopamine neurons in the ventral tegmental area (VTA) have been shown to mediate reward intake, memory, and learning. Additionally, it is unclear whether sex or the estrous cycle may influence Pavlovian conditioning, as sex- and estrous-differences have been identified in stress responses. I hypothesize that CRF receptors in the VTA are required for stress to enhance conditioned responding. To test this hypothesis, I will inject a CRF receptor antagonist (alpha-helical CRF) or a vehicle control into the VTA prior to stress in male and female rats. I will then determine how these intra-VTA injections prior to stress subsequently affects conditioned responding across Pavlovian training sessions.

Comparison of stable isotope analysis values of various leopard seal tissues
The rapidly changing climate is causing a shift in the ecosystem of the Southern Ocean . Leopard seals (Hydrurga Leptonyx), are apex predators of the Southern Ocean that heavily control the structure of the Southern Ocean food web. Leopard seals are one of the least studied apex predators on Earth, due to their remote habitat, solitary nature, and aggressive behavior. Researchers opportunistically collect samples from leopard seals to study their diet (stable isotopes; bulk nitrogen and carbon), leading to a variety of different types of archived samples. However, the comparison of these tissues and how well they represent the individual’s diet is unknown. Our objective is to compare the isotopic composition of each tissue to further inform us on leopard seal diet and similarities and differences between the tissues (whiskers, hair, blood, claws, blubber) from the same individuals. The isotopic measurement of several tissues from the same individual can provide short-, intermediate-, and long-term dietary information. Our preliminary data shows an association between two very distinct tissues, blood and whiskers. Additionally, we investigated the variation of nitrogen and carbon isotopes along the length of whiskers, providing important base-line information on the variance in isotope values from seals feeding on heterogeneous diets. Our next steps are to analyze the isotopic composition of the remaining tissues and assess the variation between the tissues based on their different turnover rates. These results will allow more accurate dietary reconstructions on the basis of isotopic analysis of the tissues of seals and other marine mammals.

Using Genetics to Trace the Ancestry and "Breed-type" of Rescue Horses
In the United States, horses (Equus caballus) are used in sports, as pets, and for work, but not for human consumption. Yet, yearly, roughly 200,000 unwanted horses are deemed for international slaughter. There is also a lack of information about the demographics of unwanted/abandoned horses, aside from not being marketable, being disabled, infirm, unattractive, dangerous, or lacking athletic ability. Adding value to these horses may allow for better placement, especially for these individuals. Because horses with known lineages and breed are usually more valuable and sought after, knowing “breed-type” and relationships may support adoption or rescue. Our goal was to evaluate the genetics of local rescued horses of unknown history and trace back their genetic ancestry to determine likely breed and kinships, using a commercial genetic testing service (Etalon INC, Menlo Park, CA). Pulled tail hair bulbs were submitted for genotyping using the Ancestry panel. Eleven individuals were evaluated for genetic ancestry composition and compared to the client database of Etalon Diagnostics to determine possible kinships. We expect that by assigning ancestry, possible related breeds and kinship, we will have a better understanding of the diversity of individuals deemed unwanted, as well as increase the likelihood of adoption after rehabilitation. Resulting data may support genetic testing procedures to determine ancestry and kinship, adding value to unwanted/abandoned horses deemed for slaughter. By determining a “breed-type” or relationship, we can better evaluate epidemiological aspects of unwanted horses deemed for slaughter.

Repurposing of naturally-derived VK-13 antimicrobial peptide using SUMO cloning vector
Traditional antimicrobials have facilitated the development of drug-resistant bacteria, indicating a need for alternatives. Antimicrobial peptides were discovered in the 1990s and are a promising next step against super-bacteria. AMPs can inactivate pathogens by disrupting bacterial cell membranes as well as modulating immune responses. AMPs can be developed to minimize dysbiosis and harm done to the host microbiome, which is an important component of antimicrobial development. I hypothesize that the effectiveness of the AMP VK-13 can be improved by fusing it to a carrier protein, termed SUMO, which is able to detoxify and produce the AMP. AMP genes and primers were outsourced and used to create ligation-independent staggered ends via polymerase chain reactions. Annealing enabled the AMP to be inserted into a SUMO cloning vector. The engineered plasmid was then transformed into BL21 Escherichia coli high-expression cells. Cell lysis and the isolation of the supernatant will be performed in order to purify the protein using Fast Protein Liquid Chromatography and a nickel affinity column for the present 6his tag. SDS-PAGE gel will be performed in order to calculate the resulting yield and purity. Beyond these experimentations, I hope to test the peptide’s toxicity towards a panel of bacteria including Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, and Staphylococcus aureus. Ultimately, the result can lead to the transfer of the AMP to Lactococcus lactis bacterium to allow for testing in the mouse model.

Identification and Characterization of C-type Lectin Isolated from the Venom of Crotalus Scutulatus Scutulatus and Its Effects on Endothelial Permeability
Snake venoms are composed of an array of toxins that serve multiple functions to ultimately aid in prey capture and digestion. The venoms of North American vipers contain ubiquitous toxins that can cause rapid local effects (e.g., tissue death, excessive bleeding, and swelling) that graduate in severity over time. If treatment is not received promptly after envenomation occurs, this cascade of events can result in the surgical removal of damaged tissue, paralysis, amputation, or death. Limited research has been conducted on the acute endothelial dysfunction caused by non-enzymatic toxins in the venoms of North American snakes. Non-enzymatic C-type lectins (CTLs) have been found to activate the integrin receptors on endothelial cells, leading to the release of proinflammatory cytokines. This, in turn, can result in cytoskeletal remodeling and increased vascular permeability. The purpose of the present study is to identify and characterize the non-enzymatic components of Crotalus scutulatus scutulatus venoms, specifically CTL, that could majorly contribute to the acute local effects of viper venoms. We isolated CTL from the venom of C. s. scutulatus using immobilized D-galactose gel. The CTL will be identified using N-terminal sequencing, and its effect on endothelial permeability of human dermal blood endothelial cells (HDBEC) and human dermal lymphatic endothelial cells (HDLEC) will be further tested. Understanding the local pathophysiology of snakebites is integral to developing more efficient and effective mitigating treatments for the immediate effects of snake envenomation.

Production of sweet potato clean stock using micropropagation and virus testing
The sweet potato industry in the U.S. is growing and with that growth upkeep of clean stock is necessary. The North Carolina State University (NC State) Micropropagation and Repository Unit (MPRU) acts as a clean center for a variety of crops, one of them being sweet potatoes. The MPRU consists of virus molecular diagnostics on sweet potatoes, micropropagation, improving greenhouse conditions and field work on sweet potatoes. Micropropagation will be used to produce virus-tested sweet potatoes and these cuttings will be assessed. In addition to the previous methods, molecular diagnostics on sweet potato plants will be executed to identify viruses on the plant over various seed generations. Over 30 viruses have been found to infect sweet potatoes worldwide and 6 of them are of interest to the MPRU. There is a lack of clean planting material in the U.S. Therefore, improving techniques of sweet potato cultivation by enhancing a clean seed program is vital to the sustainability of sweet potato production in the U.S.

Predicting Gene Expression in S. cerevisiae From Random Promoter Sequences Using Machine Learning Methods
Phenotypic variation in eukaryotes is largely determined by gene regulation. While the protein-encoding areas of the genome are responsible for creating the compounds that result in a specific phenotype, the regulatory regions of the genome add further complexity that determine the observed phenotype. One such region is the promoter, which is critical for the expression of all genes. However, the "regulatory code" of the promoter -that is, how its sequence relates to the expression level of its associated gene -is not very well understood. In the present study, we aim to obtain a better understanding of the relationship between a promoter's sequence and strength by utilizing machine learning methods to predict the level of gene expression from a yeast promoter sequence. We also compare the performances of various machine learning algorithms to determine the optimal strategy for predicting gene regulation. We find that the models trained on 3-mer data performed decently well in both classification (accuracy= 0.69, Fl = 0.69) and regression (RMSE = 1.95, R2 = 0.32); however, there is still much room for improvement. In the future, we plan to test nonlinear models such as neural networks to determine if they are better able to capture the relationship between sequence and expression. We also hope to train and test our models on a more powerful machine to improve runtimes and enable the use of larger datasets. Further research is needed to uncover whether models trained on yeast promoters can be extrapolated to other organisms, including humans.

Jackson County Hygiene Center – Eden Baucom, Sara LeVasseur, Derek Nelson, Stephanie Reyes
This presentation looks at the issues that arise for homeless individuals as a result of not having access to hygiene resources such as bathrooms, showers, washers, and dryers. This can lead to individuals not being able to care for their immediate and chronic health conditions and can result in multiple ER visits and negative long-term effects. There are programs out there that are providing these hygiene resources for their community in places like Portland and have been successful. Jackson County Hygiene Center is a proposed program that is a drop-in center in Jackson County, Oregon which would allow homeless individuals access to free public restrooms, showers, washers. and dryers. This program would hope to reduce the homeless individuals who lack access to hygiene resources in Jackson County, Oregon.

Workplace Attitude & Gratitude: How Inclusion in the Workplace Can Impact Organizational Citizenship Behaviors
In recent years there has been an emphasis on the importance of the values of organizations. Values of organizations have the possibility of impacting employees' lives. If employees are unhappy and feel undervalued they may not invest in their job further than what is explicitly stated in their job description. One way to make employees feel valued and cared for, is to develop inclusive environments. If the work setting has inclusive culture behaviors, the employees may change their mindset. For instance, employees may start to participate in organizational citizenship behaviors. In this proposed project we intend to explore the relationship between inclusive leadership, inclusive culture, and organizational citizenship behaviors. We expect to find that when there is more inclusion more employees engage in organizational citizenship behaviors. We also expect that the relationship may be strengthened by inclusive leadership in the organization. We plan on conducting this research using a non-experimental survey and using ANOVA and potentially mediation analysis to explore the results. This is valuable research because it has practical implications for leaders to improve the experience of the workforce and could benefit not only organizations but the employees within them.

Caregiver Recommendations for Prize-Based Contingency Management in Juvenile Probation
There is growing interest in training juvenile probation officers (JPOs) to deliver incentive-based contingency management (CM). However, prior research has focused on training JPOs in CM programs that target adolescent behavior and use financial incentives. We developed a prize-based CM program for caregivers of youth on probation supervision to target engagement in their child’s probation services and assessed the families’ perception of the program. Results of this study have the potential to inform the design of CM programs in juvenile probation settings. Eighteen caregivers (Mage = 42.72, SD = 8.09) who participated in a 16-week prize-based prize-based CM program as part of an ongoing randomized control trial testing the use of CM to reinforce caregivers’ engagement in their youth’s probation services, completed an in-depth qualitative interview about their perception of the program.Three themes emerged in our initial coding of five transcripts: program endorsements (κ = 0.90), modifications to implement (κ = 0.88), and elements to eliminate (κ = 0.88). Most caregivers endorsed liking the chance to win prizes. Most caregivers also reported a preference for gift cards over goods, provided suggestions for specific goods, and believed any caregiver CM program should include incentives for the youth. Finally, caregivers believed slips with no monetary value should be removed from the prize program.

Facilitation of Emotional Expression in Men
There is a popular belief that women tend to be more emotionally expressive than men. However, gender differences in emotional expression could be traced to cultural practices or expectations that are upheld for men. In this study, it is acknowledged how restrictive expressivity and perceived social support could play a part in the development of alexithymia in adult men; having difficulties in identifying, describing and expressing emotions. The purpose of this study was to better understand how to facilitate men’s ability to express their feelings and confide in others. This was achieved by collecting quantitative measures of alexithymia, emotional expression, perceived social support, and qualitative information about an experience from men’s lives through an online survey. Findings helped support the significance that social support had on mitigating the development of alexithymia traits. Correlations were also found between alexithymia and emotional expressivity scores. Common themes of men’s emotional expression will also be discussed. The pursuit of this study assisted in gaining insight into how men would feel encouraged to reach out for help or support to prevent the negative effects of the cultural perception of “masculinity.”

Enhancing Maternal Support and Infant Feeding: A Pilot Review of One FQHC Lactation Clinic
Although most women opt to feed human milk to their infants, a vast majority do not meet their breastfeeding goals. Facilitating forms of lactation support that extend the duration of breastfeeding may lead to significant physical and emotional benefits that are dose responsive. The purpose of this study is to measure the duration of breastfeeding among participants in the Waco Family Medicine lactation clinic compared to breastfeeding rates resulting from usual care at one Federally Qualified Health Center (FQHC). The research methods include comparing breastfeeding duration among clinic participants to standard rates at one FQHC. The study specifically targets low-income individuals, most of whom are enrolled in a Medicaid managed care organization. The results of this pilot may provide initial insights into the potential benefits of lactation support interventions in improving breastfeeding outcomes in underserved populations. Compared to usual standard care, patients that received lactation support through the Waco Family Medicine lactation clinic extended lactation duration by at least 32.2%. Results from this study may suggest early indications that primary care lactation support is related to breastfeeding duration. The findings may contribute to the implementation of analogous interventions in other underserved communities. Additionally, this pilot study may be used to inform future breastfeeding interventions aimed at extending breastfeeding duration and enhancing maternal and infant health outcomes among FQHC patient populations.

A Longitudinal Investigation of Factors that Contribute to Marital Quality and Stability: The Oklahoma State Newlywed Project
Maintaining high-quality long-term relationships, such as marriage, is strongly associated with overall better well-being and health, including both physical and mental health. Thus, advancing theory and knowledge on how couples maintain satisfying relationships is important. The Oklahoma State Newlywed Project is an ongoing dyadic, community-based, multi-year longitudinal study of marriage that, broadly, aims to understand factors that can explain different trajectories in marital satisfaction. That is, why do some couples begin their marriages less satisfied than others? And why do some couples remain satisfied over time whereas others do not? To this end, we are actively recruiting newly married couples to complete a multi-phase study that includes (a) an intensive baseline survey assessing couple members’ personal and relationship histories as well as myriad individual difference variables, (b) an in-person laboratory session, during which we collect hormonal samples and observational video-recorded data of spousal interactions, (c) two-week long daily diary surveys assessing daily relationship and personal experiences, and (d) four-month follow-up surveys spanning the first two years of marriage, including measures of relationship quality (e.g., satisfaction, commitment). Because recruitment and data collection is ongoing, results are pending. Nevertheless, utilizing these complex methods, we will be able to glean insights into how factors such as attachment, stress, and even hormones may influence long-term relationship quality and stability.

The Role of Cultural Identities with Colorblind and Racist Attitudes
Understanding attitudes that perpetuate racism and racist systems is essential. In the modern-day context, racism is a denial of the prevalence of racism in our society and the daily struggles that people of color experience (Keum et al., 2018). Instead, the focus tends to blame disparities not in systems of inequity and oppression but on groups as a whole. In contrast, colorblindness is the belief that racism and racist ideology do not exist or matter (Keum et al., 2018). However, prior research has indicated that White racial identity attitudes are predictive of racism (Pope-Davis & Ottavi, 1994); prior research largely conceptualized White or ethnic/racial identity (ERI) as a unidimensional construct and not take into account national or U.S. identity (USI) as another critical domain of ones’ broader cultural identification (Meca et al., 2023). This study utilized a sample of 288 college students (74.9% female, Mage=20.58, SD=2.37) to explore the relationship between dimensions of ethnic/racial and U.S. identity and colorblindness and racist ideology among non-Hispanic White college students. A series of multiple regression indicated that positive correlation between U.S. affirmation of racism (β=0.146; p<.011 ) and color blindness attitudes (β=0.188; p<.000). Additionally, U.S. exploration was significantly positively associated with racism (β=-0.145; p<.022) and colorblindness attitudes (β=-0.191; p<0.001). The results can be used to assist in preventing the diffusion of colorblindness and racist ideologies among cultural identities.

Evaluating the Behavioral and Neuroinflammatory Effects of Chronic Mild Stress in Female Mice
Unpredictable chronic mild stress (UCMS) is associated with a variety of behavioral and neuroinflammatory effects. Our lab previously failed to detect behavioral and inflammatory effects of UCMS one week following the end of stress exposure in female mice. To determine if an effect would emerge at an earlier time point, we conducted a follow up experiment using a larger set of behavioral tests assessed immediately following stress exposure. We hypothesize that the additional depressive assessments may allow us to detect effects and that using a more acute time point would reveal neuroinflammatory changes. We will utilize a two group (+/- UCMS) design (n = 11 mice/group). We ran the UCMS protocol for approximately 3 weeks, conducting 0-2 stressors per day. We monitored activity via burrowing and sucrose water preference throughout. After 3 weeks of stressors, we evaluated depressive-like behavior. After completion of behavioral testing, the hippocampus was collected for analyses of brain inflammation.

Fictional Book Genres and Trauma Healing
Creative bibliotherapy, the use of fictional media to help an individual improve psychological well being has been found useful in treating symptoms associated with different disorders such as anxiety disorder and trauma as well as aspects of emotional, cognitive, and social development more generally (De Vries et al, 2017; Sevinc, 2019). However, there is limited research on the role specific fictional genres play in trauma healing . It is especially limited in specific genres like mystery and thriller, romance, or fantasy which can feature characters experiencing traumatic experiences such as loss of a loved one, domestic violence or may not be as relatable to an individual. The data are being collected from individuals through an online survey. Individuals are readers of any genre, but were specifically recruited on romance focused book groups since it is a popular genre which also often contains trauma experiences or overlaps with other genres (e.g, fantasy) that contain these experiences. The hypothesis is that there will be differences in genres related to trauma healing, especially between romance being more beneficial in healing compared to mystery/thriller genres. Participants will report which genres they read most often, how much they read, self report trauma symptoms experienced in the past month and self report trauma healing in the past week. If results support the hypothesis, this will suggest directions for future research such as specifically focusing on benefits or harm for individual genres and trauma healing and if participating in therapy or in bibliotherapy plays a role.

Sibling Implemented Mand-Training to Increase Mand Variability in Children with Autism
Children with autism spectrum disorders (ASD) may struggle with engaging in prosocial behavior that aligns with their typically developing peers due to difficulty in verbal and social skills. Children with ASD often receive behavioral interventions to promote acquisition of verbal behavior and social skills. Researchers and clinicians commonly implement these behavioral interventions. However, it is important to evaluate the extent to which family members can implement these interventions. The purpose of the current study was to evaluate a sibling-implemented intervention consisting of script training and a lag schedule of reinforcement to increase mand variability. Mand variability refers to requesting for items using different phrases such as “can I have”, “I want”, and “may I please have”. This research was completed under the mentorship of Dr. Jessica Akers, Assistant Professor of Baylor University's Educational Psychology Department and through Baylor University’s McNair Scholars Program. We conducted the study in a clinical setting and used single-subject research design. We conducted 12 5-minute sessions using a reversal design, examining how sibling implementation of scripted mand training impacts the social skills and mand variability of the child with ASD. A secondary purpose of this study was to assess qualitative changes in the dynamic between the child with ASD and their typically developing sibling. We observed an increase in mand variability in our participant with ASD, indicating that the sibling-implemented intervention encourages both prosocial behaviors and verbal skill acquisition in children with ASD. Future research could examine the efficacy of script fading in sibling-implemented mand training.

Connections Between Burnout and ADHD Symptomatology in College Students
Burnout is a condition characterized by exhaustion, pessimism, and lack of efficacy. It can be detrimental to a student’s academic performance and may also negatively affect their personal and social well-being. Additionally, attention-deficit/hyperactivity disorder (ADHD) is a neurocognitive disorder that affects impulsivity and attention. Despite an increase in ADHD research, there is a dearth of information related to ADHD in adulthood. The symptoms associated with adult ADHD have also been found to negatively affect college students’ performance. We hypothesized that classroom burnout will be highly correlated with other types of burnout among students who met the criteria for ADHD symptomatology. Ninety-four students from a southwestern, rurally located university participated in this online research study. Upon completion of informed consent, each participant completed the Adult ADHD Self-Report Scale, an adapted version of the Copenhagen Burnout Inventory, and demographic questions. Of the total sample, fifty-one students (54.3%) met the criteria for ADHD symptomatology and forty-three (45.7%) did not. Among the ADHD symptomatology group, we found a positive correlation between classroom and personal burnout, r(51) = .73, p < .001, accounting for approximately 53% of shared variance. Furthermore, we found a positive correlation between classroom and social burnout, r(51) = .44, p = .001, accounting for approximately 19% of shared variance. This research highlights how important classroom burnout is among students with ADHD symptomatology. However, future research is needed to identify the role ADHD symptomatology plays in personal, social, and classroom burnout.

Last Words Unspoken: Discordant Military Discontent during the Vietnam War, Exploring Dennis Mora's Objection through Race and Class
During the Vietnam War, many individuals recruited in the military refrained from expressing opposition to the U.S. war efforts despite holding personal questions regarding its legality or logistics. This behavior can be attributed to the emergence of a propaganda machine within the U.S. during the Second Red Scare. Investigating the underlying reasons for silent military dissent becomes crucial as it highlights sentiments shared by many G.I.s during the Vietnam War, often stemming from their doubts about the legitimacy of a conflict seen as a "rich man's" war. The study uncovers the direct impact of race and class on deployment, as a disproportionate number of low or working-class minority G.I.s made up front-line casualties during the Vietnam War. The data and findings for this study were gathered through contacting various historical institutions, including the Wisconsin Historical Society, Library of Congress, National Lawyers Guild, Swarthmore College, and Memorial University. By cross-referencing the materials provided by these institutions, it was revealed that Dennis Mora, one of the founding members of the G.I. anti-war movement, underwent harsh treatment due to his minority status and conscientious objector stance. By examining the actions of Dennis Mora and his comrades, it was concluded that the U.S. government disapproved of conscientious objectors since they were perceived as disruptive to the war machine. As the study delves into historical infographic literature, it suggests the possibility of expanding the research to gather more evidence of the flawed nature of U.S. engagement in Vietnam.

Increasing Social Emotional Awareness with the use of Bibliotherapy in a Storytime Setting
Bibliotherapy is the use of literature to help offer self-understanding, growth, and healing. Literature on this topic suggests that bibliotherapy is a beneficial tool, allowing children to relate to the character in the book being read and applying it to their own experiences. However, there is a lack of how this affects children who struggle with dealing with their emotions in a healthy way. This research will examine the impact of bibliotherapy in increasing the social-emotional awareness of preschool-aged children. Participants will be selected from local preschools using convenience sampling. Consisting of two groups, my participants in group 1 are in the 4.5-5 age range and a younger group of 3-4.5 year olds. To measure changes in emotional awareness and social-emotional development, a pre-test / post-test model will be used. Parents and preschool teachers will complete the Social-Emotional Assessment/Evaluation Measure (SEAM™) before and after the storytime interventions. Participating children will be assessed using categorization and labeling of emotional facial expressions flashcards. Between the pre-test and post-test, participating preschoolers will engage in storytimes focusing on central emotions. Research can benefit child psychologists, librarians, and teachers, as they can use it to help create reading lists or storytime themes to support the development of specific social-emotional skills in children. Preliminary results suggest that the children understand the basic categories of emotions like happiness, sadness, and anger. However, they struggle with the identification of more complex emotions such as excitement and love.

Highlighting Latine Family STEM Talk and Beliefs through Early Childhood STEM Learning Programs
STEM education systems can change to support the assets of Latine families and learning from families must be the starting point. Emerging studies suggest that experiences with STEM in early childhood provide a critical foundation for long-term STEM-related engagement and career pathways. At this early age, talking with family members about STEM topics has been shown to contribute to STEM identities and exploring different ways of engaging with STEM (Dou et al., 2019). However, more research is needed to understand the nature of this talk within families and how it supports aspirations within specific fields, especially for Latine families with young children. In this study, we examined the beliefs that Latine families had before and after participating in early childhood engineering programs with their children and how they may utilize STEM talk to raise awareness of and develop interest in various STEM fields. To further investigate this, we conducted in-depth semi-structured qualitative interviews with three Latine families that participated in early childhood engineering programs. We used a Community Cultural Wealth (Yosso, 2005) framework as a general approach for STEM talk. By the end, we hope to highlight the ways early childhood engineering programs can engage STEM talk within Latine families and their assets that support their children’s STEM interests. This work will lead to new research on the significance of early childhood, family-based engineering programs and how STEM talk manifests among families. This research will increase awareness of asset-based approaches among researchers, educators, and practitioners when working with Latines.

The design and testing of a rhodium-based catalytic reactor for the experimental investigation of decomposition using laser absorption spectroscopy
Hypersonic test ground facilities accurately simulate high pressures and velocities but lack the capacity to simulate gas flow at high-temperatures due to thermal-structural material limitations. This necessitates the need for injection of high-enthalpy gases into hypersonic test ground facilities to model complete high-speed fluid flow phenomena. Nitrous oxide (N2O) is a high-enthalpy gas of which naturally decomposes at high temperatures into molecular oxygen and nitrogen imitating the characterization of air in hypersonic flow regimes. Nitrous oxide also decomposes at low temperatures with the assistance of precious metal catalysts. This experimental study aims to use laser absorption spectroscopy (LAS) as a proof-of-concept advanced diagnostic technique for the measurement of high-temperature catalytic nitrous oxide decomposition conversion efficiency inside a N2O catalytic gas flow reactor. Nitrous oxide decomposition at low temperatures will be initiated with the use of a catalyst consisting of cylindrical pellets comprised of rhodium supported on alumina. Data acquisition will consist of measuring N2O decomposition concentration and recorded thermocouple data from inside the catalytic gas flow reactor at varying mass flow rates. Expected results would reveal near-elimination of N2O at moderately high temperatures from the exhaust of the catalytic reactor and the presumed presence of hot molecular nitrogen and oxygen. Experimental results from this study can be applied towards improving the design and development of catalytic gas flow reactors and hypersonic ground testing facilities to fully model the characterization of high-speed fluid flow regimes as well as propel further study of using N2O as a monopropellant for space applications.

Designing, Processing, and Validating the Functionality of 3D Printed Artificial Placenta Drainage Cannulas
There are approximately 25,000 extremely low gestational age newborns (ELGANs) and 80,000 premature infants born each year that risk death and disability. The artificial placenta (AP) research project aims to help support ELGANS and preemies by recreating the fetal physiology through extracorporeal life support. In order to properly regulate the blood flow within the AP, drainage cannulas are needed. For this study, the 3D printing approach to manufacture was explored. Building off of previous models of cannulae, the current study involves an ovular cross-section as opposed to circular, proving to resolve recurring issues of cannulae splitting and collapse. It was found that this is mainly due to design and the print grain pattern. To collect data, cannulas were water and blood tested using a continuous flow pump, simulating the blood flow inside an ELGAN lamb. Currently, results show that the ovular geometry has reduced the occurrence of splitting and collapse due to negative pressures. This development is what ultimately led to the advancement of the project moving onwards to blood flow testing. With the current 3D printed 6fr cannulas, advancements have been made in the research of artificial placenta in developing a reliable form of manufacturing this device. The 3D printed approach also offers variety to better accommodate patient needs. Given this device is to be used in-vitro, it will need further testing and preparation for biocompatibility so they can be inserted into the body without risk of infection or other complications.

Retrofitting Existing Residential Buildings with PV Systems to Achieve NetZero Energy in Humid, Sub-Tropical Climates
The conversion of existing residential buildings into Net-Zero Energy Buildings (NZEBs) promises to offset a substantial portion of total U.S. greenhouse gas emissions. However, there are significant challenges to address regarding the amount of energy produced by green energy sources and the amount of energy consumed by existing residential buildings. This study makes an important contribution to the literature by simulating possible PV or PV/T systems for retrofitting existing residential buildings. The purpose of this study is to develop a cost-effective solution for retrofitting existing residential buildings with individual PV systems to achieve net-zero energy in humid, subtropical climates by simulating how different PV systems operate in a simulation. The independent variable will be defined as the amount of energy produced by various PT systems and the amount of energy consumed by energy-efficient technology used to retrofit existing buildings (i.e. added insulation, replacing HVAC, installing energy efficient appliances, etc.). After reviewing the current literature on NZEBs, the methodology involves analyzing empirical data related to residential buildings then utilizing Building Energy Optimization Tool (BEopt) software to simulate existing residential buildings’ energy production, consumption, and efficiency with the goal of optimizing them to achieve a net-zero energy production/consumption balance. Once simulations are complete, a cost-effective retrofitted NZEB solution can be proposed, specifically for humid, sub-tropical climates.

The New Buffalo: The Benefits and Harms of Indian Gaming
Native American tribes once found self-sufficiency by living off the land and killing buffalo. As time progressed, the tribes' capability to gain self-sufficiency has changed to where most tribes now promote their economic development, sovereignty, and strong tribal governments through tribal gaming. Thus, tribes have cultivated their "new buffalo" through the provision from the Indian Gaming Association. While tribal gaming brings advantages such as increased job opportunities and revenue; it also brings disadvantages such as problem gambling and increased criminal activity. This research uses an economic and political focus on these topics, asking what the benefits and harms are to Native Americans from tribal gaming. The first step in approaching these questions is to understand the development of the Indian Gaming Association since the passing of the Indian Gaming Regulatory Act. Next, scholarly written sources, legal documents, and interviews with contemporary figures fill out a portrait of the current situation. This research's purpose is to evaluate how tribal sovereignty and Native Americans are affected by the presence of the Indian Gaming Association in an economic and political sense. Although the results are not finalized, this research's theory is that tribal governments gain slight tribal sovereignty from tribal gaming; however, the U.S. government gains the most benefits from tribal gaming. This research suggests the need for the U.S. Government to preserve and protect the tribal sovereignty of Native Americans through tribal gaming instead of using them as pawns in the economic and political process.

Tax Software and Its Usefulness: Is there room for Refinement?
My research will involve trying to find out whether the software used in the accounting industry is effective and productive for accountants, who are actively relying on such software in their day-to-day tasks. This is the following question I intend to answer about accounting software: Is there a need for refinement or changes to tax software used by industry professionals? The components that could be looked upon are overall performance, likes/dislikes, and user feedback. If the current software being used is found to need help with improvements, the efficiency of accountant duties can be increased. The amount of time and energy spent by accountants is vast, due to the nature of many accounting duties. Relieving some of these duties with the addition of adequate software can improve the daily life of accountants at work, allow for more time to be spent on other matters, and reduce the stress of accounting duties. I will find out by using an online survey, which will be developed using Qualtrics. The software I intend to analyze is professional Tax Software, such as Drake Tax. These questions will be focused on the general performance, likes/dislikes, and user feedback about the software’s compatibilities. This accumulation of data will help toward the answer of whether there is a need for refinement or changes to tax software, used by industry professionals.

Trends in the Baseline Health Status of College Students in a Rural, Division III University
In Spring of 2022, approximately 15 million students were enrolled in an undergraduate college program in the United States (Welding, 2023). Of those students, it is estimated that one in three are considered clinically obese (Yashi, 2022). Obesity is the largest contributing risk factor to lifestyle related diseases like hypertension, coronary heart disease, and type II diabetes which include metabolic syndrome. Recognizing there is a lack of data pertaining to the clinical baseline health amongst college students poses an elevated risk in developing metabolic diseases at an earlier stage of their lives. This study is a response to the lack of peer-reviewed data about the baseline health of college students in a rural division III university. The purpose of this study was to assess obesity risk along with physical activity, blood pressure, oxygen saturation, glucose and lipid levels in college students. Through a Contemporary Health Problems class (KINE 3334), student researchers collected data on a rural, DIII college campus through convenience sampling of students over a three-week period. Student researchers were trained in data collection through the course. All participants completed a digital informed consent agreement prior to sample collection. Data was organized and analyzed after collection using statistical software. Through the interpreted data, this paper aims to bring awareness to students and the public about the health of college students, determine the level of risk of metabolic disease in college students, and serve as a foundation for health promotion programs in college and to stimulate future research.
