SACAD: Scholarly Activities

This study examines how undergraduate team members’ verbal communication behaviors are associated with the emotional expressions of their teammates during student project team interactions. Drawing on data from a semester-long, team-based undergraduate course, three key team meetings were video-recorded across the team life cycle. Verbal communication was analyzed using a systematic content analysis with an a priori codebook capturing emotionally relevant behaviors such as optimism, empathy, building bonds, developing others, service orientation, and task-focused communication. Nonverbal emotional expressions were assessed using AI-based facial expression analysis grounded in Facial Action Coding System research, generating average emotion scores for each team member. …

Validating Llm-Assisted Coding Of Student Leadership Teams For Formative Feedback, Jace Hesford, Magdalene Moy, Ryan Will, Brent Goertzen

SACAD: Scholarly Activities

Leadership education scholarship increasingly calls for direct assessment of leadership behaviors rather than reliance on proxy measures (Banks et al., 2023). This poster reports a validation study situated in a project-based leadership course at a midsized university. While teams meet regularly throughout the semester-long project, three meetings are digitally recorded, transcribed and analyzed to provide students with objective feedback based on the content of their communication. Team meetings are coded using an a priori framework grounded in emotional intelligence (Salovey & Mayer, 1990; Lee & Wong, 2017), with codes reflecting self-awareness, self-regulation, self-motivation, social awareness, and relational management as enacted …

Woven Color: Historical Uses Of Color Theory Woven Into Fiber Art Practice, Mary K. Greenwood

SACAD: Scholarly Activities

This semester-long project, created in Material Exploration, examines the use of historical color theory within contemporary fiber art to evoke emotion and narrative. Drawing from established color systems, artistic movements, and artist inspirations, the work explores how color relationships, such as harmony, contrast, and saturation, can communicate mood and meaning. Through experimentation with textile materials and processes, each piece integrates intentional color schemes to enhance storytelling through both visual and tactile elements. Ultimately, the project highlights how applying historical color theory within fiber art can deepen emotional resonance and connect traditional practices with contemporary expression.

Color Clash: When Opposites Create Harmony, Zachary Dean Esslinger

SACAD: Scholarly Activities

Opposites attract is usually the saying and the same can be said for colors. Complimentary colors are pairs directly opposite each other on the color wheel. Warm versus cool, bright versus high intensity these are things that stand out when these colors are paired together Red/Green, Yellow/Purple, Blue/Orange and subsequently any hues, values and tints can be used as well. complementary color pairs, but if looking at a color wheel there are twelve consisting of your three primary and the othernine coming from different hues.

The Effect Of Water Pollution In Kansas, Chaejun Park Chaejun Park, Jeanne Sumrall

SACAD: Scholarly Activities

Groundwater in Kansas shows significant nitrate contamination, with about 20% of samples exceeding the Environmental Protection Agency’s (EPA) safe drinking water limit of 10 mg/L. This indicates that a considerable portion of groundwater sources are affected by pollution levels high enough to pose potential risks to human health and environmental quality. High nitrate concentrations are strongly associated with agricultural activity and land-use patterns, particularly areas with intensive fertilizer application, irrigation, and livestock operations. In addition, more than half of all monitored wells show evidence of human influence, reinforcing the idea that nitrate contamination is largely driven by anthropogenic rather than …

From Books To Justice: Public Libraries Strengthening Legal Access Across Kansas, Lauren J. Franks, Ziwei Qi

SACAD: Scholarly Activities

Legal self-help centers across Kansas allow access to legal information for self-represented litigants in civil court cases. However, there is a lack of these centers in rural areas. In areas where this resource does not exist, libraries, which already serve as a trusted community-centered hub, can help provide legal information and resources. This project aims to identify best practices in increasing access to legal information and survey key staff including self-help center staff, court staff such as court clerks and judges, and librarians, to help inform our integration of legal self-help services into public libraries.

Ancestral Sequence Reconstruction Of Gh4, Chaejun Park Chaejun Park, Masakatsu Watanabe

SACAD: Scholarly Activities

GH4 enzymes use an unusual NAD⁺-dependent catalytic mechanism that remains poorly understood. Because of their roles in microbial metabolism and potential bioengineering applications, understanding how this mechanism evolved is important. In this study, we use the GH4 structure 1U8X as a reference for structural and functional analysis. Using ancestral sequence reconstruction and phylogenetic analysis, we inferred ancestral GH4 sequences and selected a particular ancestral node for detailed comparison with modern enzymes. These comparisons were used to examine stability, sequence conservation, and catalytic features, helping identify mutations and evolutionary transitions that contributed to the emergence of this distinctive NAD⁺-dependent mechanism.

The Role Of Dna Exoneration In The Bloodsworth Case, John T. Brasfield

SACAD: Scholarly Activities

In the Kirk Bloodsworth case, a man was falsely convicted for the rape and murder of Dawn Hamilton. He spent eight years in prison after being convicted through witness testimony, where he learned about DNA profiling. After submitting a request to check his DNA against the DNA left at the scene, he was exonerated. Later, the DNA left at the scene was checked against a database and got a hit on a convicted rapist who had been charged shortly after Mr. Bloodsworth. If there had been the same access to DNA technology during the trial or if they had listened …

Key Biomechanical Predictors Of Driving Distance, Cooper M. Scheck, Justin L. Montney, David Fitzhugh, Helen Miles, Greg Kandt

SACAD: Scholarly Activities

Abstract: This study investigated the key biomechanical factors that influence golf driving distance using 3D motion capture analysis. Nine swings from three golfers were analyzed using the Sportsbox Golf premium platform, allowing for detailed measurement of swing mechanics across nine phases of the golf swing. Variables included clubhead speed, X-Factor (torso–pelvis separation), body dimensions, and kinematic velocities.

Results showed that carry distance is most strongly associated with clubhead speed and X-Factor at impact, while X-Factor at the top of the backswing was not significantly related. Correlation and regression analyses indicated that a combination of body dimensions, swing speed, and impact …

Perceptions Of Online De-Escalation Training, May Yu-Harper

SACAD: Scholarly Activities

Higher education and professional training have increasingly adopted online and compressed course formats to meet workforce needs and expand access (Al-Youssef, 2023; Pregowska et al., 2021). While these formats provide greater flexibility for learners, they also raise important questions about course duration and its impact on student learning, knowledge gains, and course evaluation ratings (Pregowska et al., 2021). Course evaluations are widely used to assess participants’ perceptions of course quality, value, and applicability (Al-Kharusi, 2023; Loveland, 2007). Prior research suggests that course evaluation ratings may be influenced by factors beyond instructional quality, including participant background and course structure (Daskalopoulou, 2024). …

False Confessions Of A Teenage Boy: The Case Of Brian Boles And Charles Collins, Rebekah Bottner

SACAD: Scholarly Activities

On February 8, 1994, James Reid was found dead in his apartment in New York. In the days following the murder, detectives spoke to several people who lived in the building, looking for potential leads or suspects, including 17-year-old Brain Boles. Boles was initially released from questioning after he signed a statement confirming his alibi and that barely knew Reid. A month later, Boles was arrested for a separate assault and robbery. For this crime, Boles confessed, but he was then subjected to an intense and lengthy interrogation for the murder of James Reid. Eventually, Boles also confessed to the …

While traditional hazard management strategies often prioritize physical infrastructure, this research emphasizes the importance of integrating social vulnerability factors into planning processes.

Socio-economic variables including poverty, unemployment, median household income, housing vacancy, and insurance coverage were obtained from the American Community Survey. These variables were normalized and combined to create a composite vulnerability index representing areas of heightened socio-economic risk. At the same time, proximity and accessibility to critical services such as …

Finding Her Voice: Communication Challenges And Strategies Among Young Women With Autism Spectrum Disorder, Sydney Holthaus, Averi Yeo, Madison Walt, Ran An

SACAD: Scholarly Activities

Background/Rationale

Research on autism spectrum disorder (ASD) has historically centered on males, leaving the communication experiences of autistic females underrepresented (Lai et al., 2015). Although autistic females make up a substantial portion of the autistic population in the United States (Centers for Disease Control and Prevention, 2023), far less is known about how communication differences affect their everyday lives. Diagnostic processes may also overlook communication-related signs in autistic women, particularly when masking or compensatory behaviors reduce the visibility of underlying pragmatic and social communication differences (Dean et al., 2017; Hull et al., 2020; Rynkiewicz et al., 2018). As a result, …

A Heavy Burden: Linking Body Mass, Locomotion, And Osteopathology In Aphelops And Teleoceras, Kaden W. Moses, Amanda Peng

SACAD: Scholarly Activities

The Miocene of North America was characterized by a transition from C3 woodlands to more open C4 grasslands. This transition drove sympatric rhinoceroses of the Ogallala Group, Aphelops and Teleoceras, to adapt in different ways. With the two responding differently, their osteological morphology should reflect this. An animal’s mass and locomotor habit are reflected by their skeleton as is the record of injury, stress, and disease. Twenty-two unassociated specimens (10 Teleoceras humeri, 10 Teleoceras femurs, and 2 Aphelops humeri), from the Fort Hays Sternberg Museum paleontology collection were analyzed. To study this relationship, the femur and humerus were selected …

Effectiveness Of The Mediterranean Diet For Sustained Weight Maintenance Following Glp-1 Medication Discontinuation: A Longitudinal Prospective Study, Nitya Reddy, Josephine Thomas, Julie Salam

Department of Nutrition Student Projects

Glucagon-like peptide-1 (GLP-1) receptor agonists are effective for short-term weight reduction in adults with obesity, yet weight regain is frequent after discontinued use of the medication. Identifying sustainable dietary approaches that support long-term weight maintenance is imperative. The Mediterranean diet has been associated with improving metabolic health and resistant weight control, suggesting it may be an effective strategy for the transition off GLP-1 therapy. Men and women ages 45-55 that are diagnosed with Type 2 diabetes and receiving GLP-1 receptor therapy are the targets of this study, specifically those who plan to discontinue medication within the next three months. On …

Oral Butyrate Supplementation In Patients With Als: Impact On Gut Microbiota And Disease Progression, Annabelle Keller, Kaydee Kinnett, Camaryn Barbanel, Trinity Blakeney

Department of Nutrition Student Projects

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. Emerging evidence suggests that alterations in gut microbiota—particularly reductions in butyrate-producing bacteria—may contribute to neuroinflammatory pathways involved in disease progression. Observational studies in patients with ALS and preclinical findings from transgenic mouse models demonstrate gut microbial dysbiosis, intestinal barrier dysfunction, and improved survival following butyrate supplementation, suggesting the potential role of butyrate availability in ALS pathophysiology. The present study investigates whether oral butyrate supplementation can modulate inflammatory responses, improve gut microbiota composition, and slow functional decline among patients with ALS. Participants will be recruited from …
