The perceived level of enjoyment in sports violence: An experiment examining how sports commentary, fanship, and gender affect viewer emotions
This poster presents the purpose, methods, and expected results of a current on-going study. The experiment’s main focus is to test the perceived level of enjoyment of viewers through an experiment that will examine how sports commentary, fanship, and gender affect their emotions while they watch various violent sports clips. These clips will feature both televised National Football League and National Hockey League videos. Through manipulation tests and a main study, videos, surveys, and detailed data collection will be implored. References regarding the current study are available upon request
Reducing the Stigma Associated with Maternal Substance use Disorder in a Rural Midwest Hospital and Clinic
The purpose of this study was to determine if an educational resource provided to maternal healthcare providers, more specifically, providers in a Midwest regional hospital and clinic, would reduce the stigma associated with maternal substance use disorder (SUD). This project also aimed at increasing provider knowledge on the disease process of maternal SUD and current treatment guidelines.
A quantitative research design was used for this study. There was no control group; therefore, it is a quasi-experimental study. Qualtrics were utilized to design a pre-test and post-test. An email including a brief description of the study, an invitation to participate, and a link to the pre-test were sent to Coffeyville Regional Medical Center Women\u27s Health Unit and Women\u27s Health Clinic employees. This included nurses, obstetric gynecological physicians, a pediatrician, a family practice physician, and a nurse practitioner. Following the pre-test, an electronic handout was provided followed by a post-test. The pre-test and post-test results were compared to determine if the educational handout decreased the healthcare providers\u27 stigma associated with maternal substance use disorder and increased their knowledge of the disease.
In conclusion, the study found that providing an educational resource decreased provider perceived stigma and increased their overall knowledge of maternal SUD. The study also revealed the provider\u27s desire to become role models and a need for increased education on maternal SUD. Providers should be encouraged to stay abreast on the topic, including maternal SUD evidence-based treatment guidelines, and the disease process. Healthcare providers should also continue to evaluate personal bias related to this topic
Suitability of Paleosols from the early Miocene Kiahera Formation, Rusinga Island, Kenya for Stable Isotopic Analysis
Climate change and concurrent environmental changes play an important role in understanding biological evolution through time, because climate change may be a stressor that promotes flora and fauna adaptations. Nearly a century of geological and paleontological study on Rusinga Island, Lake Victoria, Kenya, has made it a touchstone for understanding early Neogene floral and faunal evolution. This is because sediments that were deposited between ca. 20-17 Ma, during the early Miocene, are famous for the presence of the early ape, Ekembo, as well as more than 100 species of mammals. The basal Kiahera Formation has largely been understudied, but recent preliminary work suggests it contains an abundance of fossil soils (paleosols), as well as uniquely preserved fossils. Here we report on the clay mineralogy of four different paleosols within the Kiahera Formation using x-ray diffraction (XRD) analysis. Preliminary XRD analysis reveals samples dominated by illite, kaolinite, and mixed layer clay minerals. In particular, sample LM17KF contained an abundance of clay minerals, no evidence of diagenetic alteration, and the desired two clay mineral suite of illite and kaolinite. This sample was determined to be the most robust candidate for future stable isotopic analysis. These results advance our ability to quantitively assess climate on the island, particularly in a formation that is important for its small mammal communities. Furthermore, this work, suggests there are phyllosilicates that are appropriate for 18O analysis which may result in our better understanding the role the East African monsoon played in the environment during this time

Bog Turtle (Glyptemys muhlenbergii) Population Dynamics and Response to Habitat Management in Massachusetts
The Bog Turtle (Glyptemys muhlenbergii) is a federally threatened species that occupies isolated pockets of open-canopy fens. This long-lived species is susceptible to habitat loss and degradation; thus, the conservation of known populations and management of their habitat is critical to the species’ survival. Long-term (multi-decadal) assessment is important for determining population trends and responses to ongoing habitat management. I assessed population demographics (abundance, survival) and spatial distribution (home range) of two Bog Turtle populations in Massachusetts that have been managed since the late 1990s by treating invasive species, thinning woody vegetation, and mitigating flooding. The results of this study were compared to two previous studies conducted in 1994–1997 and 2005–2009 to evaluate the response to habitat management. Estimates of adult population abundance increased from the first study period (Site 1 X̅= 37.3 ± 10.4, Site 2 X̅= 36.2 ± 3.2) to the last study period (Site 1 X̅= 65.1 ± 17.9, Site 2 X̅= 42.5 ± 10.9) across both sites. Estimates of annual survival across all study periods remained above 90% at Site 1 and were 100% for two years at Site 2. I constructed 95% minimum convex polygon (MCP) and 95% kernel density estimation (KDE) home ranges for 71 turtles. At Site 1 there was no significant influence of the study period on home range estimates. The increase in abundance estimates, high survival, and stable home range sizes at Site 1 suggest that ongoing management has maintained quality habitat. At Site 2, the average home range size decreased by approximately half after the first study period in response to flooding but increased in the current study. Fluctuations in population abundance, and home range size at Site 2 throughout the study period reflect the cycles of habitat degradation and habitat management. My results indicate that habitat management efforts implemented since the late 1990s have provided quality habitat for the two Bog Turtle populations in Massachusetts while also mitigating long-term negative impacts on the populations. This further supports the need for long-term analysis of Bog Turtle populations, especially at sites where active habitat management is occurring
Impact of Art on At-Risk Students
The research study focused on the influence and impact of art education on at-risk students who have experienced or are experiencing trauma. Through support of literature, including scholarly journals and case studies, and classroom observations of the researcher’s students from an inner city school in southeast Washington, D.C., it was concluded that not only does art impact at-risk students education, but it does so, positively. The classroom observations included five principal participants in both elementary and middle school, three boys and two girls, whom all live in a housing project near their school. Information was gathered about these students through both researcher observations and personal communications with the school psychologist. In combination with the student participants, data was gathered from literature —mainly from the works of Eleanor D. Brown who has done extensive research on the effects of the arts on at-risk students who have experienced trauma and/or chaotic situations. The literature and student observations were used to support one another in a cohesive, coherent way. The literature helped to decipher some of the classroom observations and better understand the reactions and responses of students. The study revealed that art education affects students in several ways including influencing the child’s education as a whole, art as a coping mechanism, school readiness, and a child’s general wellbeing. Implications of the study are the resulting affects on art education as a whole, including policy writing and the field of arts advocacy
