Full text linkIntegration of Generative Artificial Intelligence (Gen AI) in Academic Research: Perceptions of Aspiring Educational Leaders
Full text linkAs aspiring educational leaders, principal candidates must understand the widespread impact of generative artificial intelligence (Gen AI) in education. This qualitative phenomenological study explored the perceptions of aspiring educational leaders regarding Gen AI in academic research, highlighting the ethical concerns and challenges they perceive, revealing potential opportunities for AI integration in education, and assessing how these perceptions may influence their future leadership practices. The theory guiding this study was the distributed cognition theory, as it shows the dynamics of human cognition and AI cognition, making it possible to understand the perceptions of aspiring educational leaders regarding Gen AI integration in academic research. By examining these aspects, the research provided insights into how aspiring educational leaders might approach and implement AI technologies in academic research and education contexts. The research was conducted through a reflection assignment at the end of an introductory research course. The reflection prompts included demographic and background information, perceptions of the ethical use of Gen AI tools, the role of Gen AI tools as research assistants, the effectiveness and challenges related to using Gen AI tools and leveraging Gen AI\u27s potential in education as an aspiring educational leader. The archived reflection data were analyzed using a qualitative phenomenological design method. The study sought to provide insights that could inform professional development, strategies for technological integration, and institutional approaches to Gen AI adoption in academic research courses. The research highlighted how emerging educational leaders perceive Gen AI\u27s role in academic research and educational settings, moving beyond surface-level assessments to understand the complex interplay of technological, pedagogical, and personal factors
The effect of biosolid/soil composition on growth and uptake of zinc (Zn) by broccoli (Brassica oleracea var.) under greenhouse conditions
No full textWastewater sludge (also known as biosolids) is commonly applied to agricultural and forestry land, offering the advantage of recycling nutrients and organic matter from the waste material back to the land. This study investigated the influence of biosolids on the uptake of Zn by broccoli (Brassica oleracea var.), a commonly consumed vegetable, grown in biosolid-amended soil compositions, by using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM/EDX). Broccoli was grown in soil amended with composted wastewater sludge at five different compositions (0, 25, 50, 75, and 100% wt/wt) treated with 100 ppm Zn at the beginning. Brassica oleracea var. (broccoli) plants from pot experiments were harvested after 30 days and Zn concentrations in plant parts (root, stem, and leaf) were analyzed by using flame atomic absorption (FAA) spectroscopy. Harvested biomass increased by 141–454% in comparison to the control (zero% wt/wt biosolid). The best growth was apparent at 25% (w/w)–75% (biosolid wt/wt), with Zn concentrations in plant parts found in the order [Zn]root \u3e [Zn]shoot \u3e [Zn]leaf. SEM/EDX and FTIR spectral data show the presence of carboxyl functional groups that can bind Zn. The investigation shows that biosolids influence the yield and root-to-shoot-leaf transfer of Zn

No full textNeotropical catfish diversity in rivers of the Guiana Shield: A Combined Approach Using Taxonomic, Functional, and Isotopic Tools
Full text linkRivers of the Guiana Shield in South America are very heterogenous, containing a mosaic of habitats and environmental characteristics ideal for maintaining high freshwater biodiversity. The connection between the Essequibo and Amazon rivers via the Rupununi River during the wet season plays an important role for the great diversity of Neotropical ichthyofauna. Neotropical catfishes (Siluriformes) are the second most diverse group of freshwater fishes, after the Characiformes. They span a wide range of body sizes and exhibit diverse trophic specializations, making them ideal organisms for studying the influence of body size variation on community organization and ecosystem function. We explored the taxonomic, functional, and feeding ecology among neotropical catfishes in two rivers in Guyana to examine overall feeding diversity and relationships between body size and trophic position of catfish species in these rivers
Professional Sport Venue Threats, Security Measures, and Technological Solutions
Full text linkSeveral incidents involving large crowds have led venue security directors to adopt preventive strategies. Venue organizers should foster a safe and secure environment, which requires assessing risk levels, recruiting and training staff, exercising plans and protocols, and leveraging technology solutions. The purpose of this study is to explore professional sport venue threats, security measures, and technology utilization. Security directors (n=52) from five major sports leagues in the United States (MLB, MLS, NBA, NFL, and NHL) participated in the study. Key findings focus on staffing, training and development, fan behavior, and facility operations. Recommendations include investing in multiple strategies to enhance venue safety and security, including staff retention and training strategies, utilization of multiple communication platforms, incorporating robust policies and procedures, and investment of technological and analytical tools as budgets and needs permit. Understanding the current status of professional sport venue safety and security concerns and potential solutions can assist venue directors in developing best practices, policies, and procedures to enhance security and provide a safe environment for patrons and participants

EXPLORING STRATEGIES TO ENHANCE STUDENT PERFORMANCE IN ONLINE HIGHER EDUCATION COURSES
No full textOver the past decade, online learning in higher education has drastically expanded. However, students’ success in coursework has considerably decreased, leaving universities concerned about the rigor of online learning. Research indicates there is a need for built-in supports for students enrolled in online courses. Utilizing Academic Coaches (ACs) in the online classroom is a way to provide supports to students. The purpose of this research is to determine what strategies are perceived as effective by ACs within the online classroom. Regarding engagement, ACs perceived the following strategies to be effective: Constructive, detailed feedback; being available for student specific support via email; attending Zoom meetings; and participating in course discussion boards. To assist students in self-efficacy ACs perceived the following strategies to be effective: Encouragement, consistent communication via email and course announcements, clear and consistent feedback (especially on repeated errors and mistakes), continued virtual presence in the online classroom, and engaging underperforming students
Innovative Recruitment and Retention Strategies in Higher Education: A Student-Centric Approach
No full textIn response to the evolving landscape of higher education, Innovative Recruitment and Retention Strategies in Higher Education: A Student-Centric Approach explores practical, student-centered strategies that enhance both enrollment and retention. As institutions compete for students amid rising operational challenges, the need for dynamic recruitment practices and personalized engagement becomes paramount. This research emphasizes the significance of a holistic approach that integrates data-driven tools, student life programs, and flexible learning models to meet the diverse needs of modern students.
Drawing on insights from students and academic staff at Stephen F. Austin State University, the study identifies key strategies that foster student belonging, engagement, and persistence. Techniques such as targeted analytics to monitor at-risk students, adaptive learning environments, and collaborative academic communities are highlighted as essential components for student success. Moreover, institutions that implement measurable retention goals and continuously assess student satisfaction are better positioned to navigate enrollment challenges.
This paper argues that colleges and universities must adopt a student-centric recruitment model that leverages innovative solutions, cultivates belonging, and ensures academic support throughout the student journey. Ultimately, institutions that prioritize both recruitment and retention will create sustainable educational environments that enhance student outcomes and institutional success
