Using unmanned aerial vehicle oblique photogrammetry technology to obtain field outcrop image data and establish a three-dimensional model for observation, the NEE and NNW fractures are the most developed in the Yanchang Formation of the study area, while the NW and NNE fractures are slightly developed, all of which are high angle vertical fractures and belong to regional structural fractures. The NNW oriented cracks are restricted by the NEE oriented cracks and developed in the late stage. Combined with the analysis of regional geological background, fracture intersection relationship and tectonic stress field, it is considered that there are two stages of fractures in Dongjiahe, namely, the late Indosinian and Yanshanian.展开更多

This study investigates the relationships between knowledge modeling, institutional memory, leadership styles, technology, and administrative efficiency at the University of Cape Coast (UCC). The study sought to identify the challenges and opportunities in integrating digital tools into administrative processes and to provide actionable recommendations for improvement. A mixed-methods research design was employed, combining quantitative analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM) with qualitative thematic analysis of interviews. The findings revealed key challenges, including resistance to change, fragmented knowledge repositories, and inadequate funding, alongside opportunities such as centralized knowledge systems, cost-effective open-source tools, and capacity-building initiatives. The study highlights the importance of strategic leadership, robust policies, and investments in digital infrastructure to enhance administrative practices. Policy implications include the need for clear digital transformation guidelines and leadership training to foster innovation and collaboration. Recommendations include investing in scalable digital tools, implementing comprehensive capacity-building programs, and promoting stakeholder engagement to drive successful digital integration. These insights provide a roadmap for UCC and similar institutions seeking to optimize administrative efficiency through digital transformation.展开更多
