Limb Differences in Hamstring-to-Quadricep Ratio Across Velocities in Collegiate Women’s Soccer Athletes
Get PDFPurpose: This study examined differences in the hamstring-to-quadriceps strength ratio (H:Q) between dominant and non-dominant legs in collegiate women soccer athletes. Methods: Eleven NCAA Division I female soccer players participated; one was excluded due to equipment malfunction. Following a standardized warm-up, athletes completed unilateral isokinetic knee extension and flexion on an isokinetic dynamometer at 60°/s, 180°/s, and 300°/s. For each leg and velocity, athletes performed three submaximal trials followed by five maximal effort repetitions, with 60 seconds of rest between velocities. A two-way repeated measures ANOVA was conducted to assess differences in H:Q ratios between the limbs across velocities. Results: No significant (p\u3e0.05) interaction was observed between the legs across velocities for hamstring or quadricep strength. Strength was significantly (p\u3c 0.05) decreased as speed increased. A significant interaction was observed for H:Q, with the dominant leg displaying a significantly higher H:Q. Additionally, the H:Q increased significantly from 60°/s to 180°/s, with no further significant change at 300°/s. The dominant leg showed a tread (p=0.06) toward higher H:Q at 60°/s and was significantly greater at 300°/s. Conclusion: The athletes displayed a greater H:Q in the dominant leg, suggesting the non-dominant leg requires targeted training, particularly at higher movement velocities
The Application of Gibberellin on Dwarf Mutant Millet Plant (Setaria viridis)
Get PDFGibberellin is a hormone found in many plants whose purpose is to promote the growth of stems and leaves. The application of gibberellin in differing concentrations was applied to different strains of dwarf mutant millet plants and was compared to a control of nonmutant wild-type millet plants. After the initial sprouting of each seed, 4 different concentrations of gibberellin: 0g gibberellin/1L water, 0.02g/L, 0.05g/L, and 0.15g/L, were applied to the stem of each plant. A regression analysis was performed on the heights of each plant to determine the effectiveness of the varying gibberellin concentrations on the growth of millet plants. The study will determine whether the highest concentration of gibberellin will encourage the growth of taller millet plants
Learning Design and Technology: Do students prefer the mobile app or desktop version of Canvas LMS?
Get PDFOne point is clear as technology and internet use evolve: it has become a crucial piece of education. To adapt, professors and faculty must keep up with the changes in education technology. One example of education technology utilized is the Canvas Learning Management System (Canvas LMS). This study aims to understand how students at Lindenwood interact with their coursework, specifically, how they interact with the desktop platform and the mobile app, and what challenges arise when using Canvas LMS. The study involved 32 participants, and a questionnaire was used to collect the data. The quantitative data was analyzed using descriptive statistics, and the qualitative data was analyzed using thematic analysis. Results indicated that students significantly preferred the desktop platform. Implications concluded that students at Lindenwood use both versions of Canvas; the desktop platform is preferred due to its formatting, upload speed, and the ability to use extensions that enhance accessibility
Investigating the Effects of Gibberellin Treatments on Different Dwarf Millet Genotypes and Identifying the Mechanism Responsible for Genetic Dwarfism
Get PDFGibberellins (GAs) are essential plant hormones involved in regulating growth and development, particularly in stem elongation, seed germination, and flowering. In cereal crops like millet, dwarf genotypes are of agricultural interest due to their potential for increased stability and yield efficiency. However, the genetic mechanisms underlying dwarfism in millet remain unclear. This study investigates the response of various dwarf millet genotypes to gibberellin treatments and seeks to determine the genetic basis of their dwarfism. We hypothesize that genotypes with gibberellin biosynthesis deficiencies will exhibit increased stem elongation when treated with gibberellin, while genotypes with signal transduction defects will show minimal response. Using a controlled greenhouse experiment, we evaluate growth differences among dwarf mutant and wild-type millet strains under gibberellin treatment. The results indicate that the wild-type and Dwarf 1 genotypes exhibited significant stem elongation following gibberellin application, while Dwarf 2 showed moderate elongation, suggesting a partial response. In contrast, the control groups demonstrated limited growth, indicating that gibberellin treatment significantly influenced elongation in susceptible genotypes. By identifying the genetic factors affecting gibberellin response, this research enhances our understanding of hormone regulation in cereal crops, contributing to the development of improved millet varieties for sustainable agriculture
A Rare Case of Anomalous Left Coronary Artery from Right Cusp in a Young Athlete
Get PDFThis case report evaluates a 15-year-old male diagnosed with Anomalous Left Coronary Artery from Right Cusp. This rare condition often goes unnoticed until a tragic event occurs. In March 2022, a teenage athlete was completing practice when he suddenly collapsed. Fortunately, a police officer was already in the parking lot when teammates and coaches flagged them down. Emergency medical services arrived, and the athlete was transported to a nearby hospital. Despite extensive medical interventions and spending 35 days in a coma, he unfortunately succumbed to the condition. This case report aims to raise awareness of Anomalous Left Coronary Artery from Right Cusp and highlights the need for early identification and intervention. The goal of this case report is to raise awareness in the risk of sudden death in young athletes by incorporating a more in-depth preparticipation exam from a cardiovascular standpoint

Enhancing Metacognitive Competencies through Human-Centered AI: The Role of Custom-Trained Intelligent Agents in Workforce Upskilling
Get PDFThis editorial examines the integration of human-computer intelligent interaction (HCII), specifically through human-centered artificial intelligence (AI) and custom-trained intelligent agents, to foster metacognitive competencies critical for workforce upskilling. With 59% of the workforce projected to require substantial upskilling by 2030, developing personalized AI models tailored to individual cognitive and learning profiles presents an innovative pathway. These custom-trained agents leverage human-computer interaction (HCI) technologies and machine learning methodologies to enhance understanding of one’s own learning processes-metacognition-thus empowering individuals to optimize their future learning and adaptability. This approach not only enhances the individual’s ability to engage effectively with complex tasks in the workplace but also supports lifelong learning strategies mandated by contemporary labor markets. The editorial synthesizes current research findings and theoretical frameworks to explore the transformative potential of AI-driven metacognitive training in education and industry, proposing future directions and considerations for widespread implementation
Creating a Co-teaching PLC to Help Find Practical Solutions for Problems in Co-teaching at a Suburban Middle School
Get PDFThe research focused on addressing equity and communication challenges in co-teaching through the implementation of a Professional Learning Community (PLC) and peer mentoring within a suburban middle school. The study took place in a predominantly white, lower-middle-class suburban school that utilized co-teaching across various subjects to provide students with disabilities greater access to the general education curriculum in the least restrictive environment. The primary objective was to establish a PLC composed of co-teachers from different disciplines, leveraging existing co-teacher training strategies to improve equity and communication within co-teaching partnerships. The PLC operated through an online forum, where the researcher, serving as a peer mentor, facilitated discussions and the sharing of strategies to support co-teachers. Data was collected using pre-and post-surveys, alongside reflection surveys completed after co-teachers implemented new strategies in their classrooms. The findings indicated a positive impact on both communication and equity within co-teaching teams. A significant outcome was that many special education co-teachers, who often felt marginalized in co-teaching partnerships, reported feeling empowered and confident in taking on teaching roles and team-teaching alongside their general education counterparts. This shift not only enhanced the equity between co-teachers but also contributed to a more inclusive and supportive teaching environment. The study adopted a human-centric approach emphasizing the development of teacher relationships and collaboration to improve student learning in co-teaching classrooms. The focus on building stronger connections among co-teachers resulted in noticeable organizational change within the school as co-teaching dynamics evolved to be more balanced and effective. The collaborative nature of the PLC fostered an environment of mutual support and growth. Overall, the study highlighted the potential of PLCs to promote equity and communication, empowering co-teachers to engage more fully in their roles and create more inclusive and effective learning environments for students with disabilities
