ABSTRACT
Coastlines have irregular shapes, are known to have fractal properties, and are formed and changed by various activities in nature. Fractals are geometric shapes with detailed structures found at any scale, and they appear very similar in different magnifications. Such a property of fractals is called self-similarity. Fractal dimension is a mathematical term that measures the complexity of a pattern, an image, or a signal by quantifying the dimensionality of fractals. Since coastlines have fractal properties, the fractal dimension can be calculated to measure the degree of irregularity in coastlines. In this study, NetLogo and a high-resolution image of the coastline of Negros Island in the Philippines were used. A box-counting dimension approach and algorithm were implemented and utilized on NetLogo to measure its fractal dimension. Results showed that the fractal dimension of the Negros Island is 1.018, which is similar to the fractal dimensions of other coastlines in the literature, although it has a relatively lower value than the rest, indicating that tectonic fault systems in this island exert strong structural control; in effect, it has less geometric complexity and a relatively smoother coastline. These results confirm the accuracy of the algorithm and the model applied, which is not far from the existing box-counting dimensions as computed by many researchers. With this, the fractal dimension of the coastlines of other islands in the Philippines, especially those challenging coastlines, can be computed using this algorithm.

Editor's Note
Research, at its core, is about people. Whether conducted in laboratories, classrooms, communities, or organizations, meaningful research seeks to understand human experiences, address societal challenges, and create pathways toward a better future. As both a researcher and educator, I have always believed that knowledge becomes most valuable when it transcends academic boundaries and contributes to real-world transformation. The articles featured in this issue of the Journal of Higher Education Research embody this very principle. Volume 13, Issue 1 presents a diverse collection of studies that examine leadership, education, student development, social welfare, environmental sustainability, technology adoption, and institutional effectiveness. While the topics vary considerably, a common thread emerges throughout the issue: the resilience of individuals and communities in navigating change and the importance of evidence-based solutions in addressing contemporary challenges. The issue opens with the study of Latido and Dy, who explore the lived experiences of novice teachers-in-charge suddenly entrusted with administrative leadership roles. Their findings remind us that leadership is often learned through experience, strengthened through mentorship, and sustained through collaboration and integrity. The importance of supportive leadership is further highlighted in the work of Aurelio and Yap, whose study examines how school leadership behaviors influence teachers' mental well-being. At a time when educator wellness has become an increasingly important concern, their findings reinforce the responsibility of educational leaders to cultivate environments built on trust, participation, and mutual respect. Focusing on the needs of learners, Angela G. Kliatchko investigates the psychological needs and support systems of junior high school students. The study offers valuable insights for schools seeking to strengthen mentoring initiatives and provide meaningful support for students' social and emotional development. Complementing this perspective, Lagman, Berboso, Ganub, and Ignacio examine the experiences of student-athletes as they navigate the demands of academic and athletic excellence. Their work reminds us that student success requires institutional systems that recognize the whole person, not merely academic performance. Beyond the school environment, this issue also highlights the role of research in promoting sustainable communities. The study by Pillo, Montelibano, Gemotea, and Lorilla examines community-based tourism as a strategy for the conservation of the endangered Irrawaddy dolphin. Their work demonstrates how local participation, environmental stewardship, and responsible tourism planning can contribute to biodiversity conservation while creating opportunities for community development. One of the strengths of JHER has always been its openness to interdisciplinary scholarship. This is exemplified by Chard Aye R. Alova's investigation of the fractal dimension of the coastline of Negros Island using computational modeling and fractal geometry. Such studies remind us that scientific inquiry can offer fresh perspectives on understanding our natural environment and the complexities of the world around us. As society continues to undergo rapid digital transformation, understanding technology adoption has become increasingly relevant. The article by Hortillo, Tan, Fiel, Quindipan, and Celestial explores the factors influencing mobile payment adoption among Filipinos. Their findings contribute to the growing body of knowledge on financial technology and provide useful insights for policymakers, businesses, and digital service providers. The transformative power of education is further highlighted in the study by Pandan, Bachinela, Baylosis, Salud, and Pontera, which evaluates the relevance of scholarship programs in the lives of university graduates. Their findings reaffirm what many educators have long believed, that scholarships are more than financial assistance; they are investments in human potential, social mobility, and nation-building. Finally, Ganub, Ignacio, Pestaño, and Ramos bring attention to the often-overlooked experiences of care providers in youth formation centers. Their narratives reveal both the challenges and rewards of serving vulnerable populations and underscore the importance of institutional support for those who dedicate their lives to caring for others. As Editor-in-Chief, I am encouraged by the breadth and quality of scholarship represented in this issue. The studies published herein demonstrate the capacity of research to illuminate problems, challenge assumptions, and inspire action. More importantly, they reflect the commitment of researchers to generate knowledge that serves communities, informs policy, and contributes to the common good. On behalf of the Editorial Board, I extend my sincere appreciation to our authors, peer reviewers, and editorial staff through the leadership of Dr. Lota Largavist, the Director of the Publication and Engagement Office, for their dedication to scholarly excellence. I also thank our readers, whose continued engagement sustains the pursuit of meaningful and impactful research. As we navigate an increasingly complex world, may the studies in this issue inspire deeper inquiry, stronger collaboration, and a renewed commitment to using research as a force for positive change. Enjoy reading the current articles! Sincerely, JOVAL N. MARTINEZEditor-in-ChiefJournal of Higher Education Research Universty of St. La Salle
