Publication Interseeding cereal rye and triticale into cool-season perennial pastures - data(2024)No-till drilling cereal rye (Secale cereal L.) and triticale (x Triticosecale Wittm. ex A. Camus.) into existing perennial pastures may increase the early spring forage inventory while maintaining beneficial ecosystem services inherent in no-till pasture systems. This interseeding system has not been well documented with cereal rye and triticale in majority tall fescue (Lolium arundinaceum (Schreb.) Darbysh.) and orchardgrass (Dactylis glomerata L.) pastures. An equal mix of cereal rye and triticale was drilled into existing pastures in early fall of 2020 and 2021. Cereal rye and triticale were interseeded at 0, 67, and 135 kg ha–1 with either 0 or 45 kg nitrogen ha–1 at planting in a 2 × 3 factorial randomized complete block design with four replications. The forage was harvested the following spring at boot stage and analyzed for herbage accumulation and nutritive value. Herbage accumulation increased by 500 kg ha–1 after interseeding 135 kg ha–1 of rye and triticale. Adding 45 kg nitrogen ha–1 independently increased dry matter herbage accumulation by 474 kg ha–1. Although, interseeding rye and triticale moderately reduced nutritive value parameters compared to the pasture, the nutritive value in all treatments remained high (relative feed value 135 with 17% crude protein). Fall nitrogen fertilizer increased herbage accumulation but had no effect on nutritive value. This shows that interseeding rye and triticale into pastures can be an applicable strategy to boost spring herbage inventory in perennial cropping systems dominated by cool-season grasses while maintaining good nutritive value.Publication AI in Education: The Impact of Reusable Learning Objects(2024)The rapid adoption of e-learning platforms amid the COVID-19 pandemic has transformed a new era in education, marked by a profound integration of artificial intelligence (AI). This paper explores the emerging interest in AI-enhanced educational tools, particularly in the context of reusable learning objects (RLOs). RLOs, powered by machine learning algorithms, offer personalized learning experiences tailored to diverse student needs and learning styles. As educators and institutions seek innovative methods to engage learners and optimize teaching resources, RLOs arise as a promising solution. However, the deployment of RLOs poses both opportunities and challenges within existing educational frameworks, prompting questions about their potential advantages and difficulties. It is essential to comprehend the psychological frameworks that shape the perceptions of RLOs among educators and students to ensure effective undertaking. This study aims to address these questions through semi-structured interviews with educators and students, alongside the development and deployment of a prototype RLO. By examining user experience, interface design, privacy considerations, and security implications, we were able to see current challenges and solutions in curriculum development and gain insights into the evolving landscape of AI-powered educational tools and their impact on teaching and learning processes. These results will build on the existing research of AI in education as the study sheds more light on the current body of knowledge, important for today’s evolving technology as AI continues to integrate into education.Person Publication Understanding the College Experience of Students with Functional Gastrointestinal Disorders(2024-05)Studies have shown undergraduate students with a functional gastrointestinal disorder (FGID) such as irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), functional dysplasia (FD), or other related functional gastrointestinal disorders have a greater level of perceived stress and a greater difficulty during the transition to college than their healthy peers. There is limited research on how undergraduate students with FGIDs conceptualize their disease, cope mentally and physically, and manage symptoms during the college experience. Because diet is essential in FGID symptom management, the current study aims to understand how on-campus dining options impact the mental and physical health of students with FGIDs and how social, emotional, and personal environments impact their disease management. For many first and multi-year undergraduates, attending post-secondary education includes a dining plan managed and provided by the college or university. Understanding how the foods and resources provided are inclusive to those with FGIDs could help explore the importance of proper nutritional options and emotional support networks to provide insight into the lived experience of undergraduates with FGIDs. This study utilized qualitative in-depth semistructured interviews to better understand how functional gastrointestinal disorders shape the college social, personal, and nutritional experience and to understand how on-campus dining services impact symptom and disease management. The results may be valuable for campus administrators, health and dining service professionals, and others who make decisions about campus resources and wellbeing.
