Abstract

This study analyzes and compares the perceptions of Chilean public-school principals with varying levels of effectiveness regarding leadership practices aimed at improving learning. The research is structured around four key dimensions of educational leadership: setting direction, redesigning the organization, developing people, and managing the teaching and learning process. The sample consisted of 48 educational establishments belonging to three Local Public Education Services (SLEP). The results show that leaders of highly effective establishments perceive their leadership capabilities more highly, especially in the dimensions of establishing direction and developing people. The findings suggest that collaborative leadership, support for teacher development, and a focus on learning outcomes are valued as key to strengthening educational management.

Keywords : leadership for learning, school management, management effectiveness, public schools.

Abstract

Atherosclerotic disease significantly impacts patients with type 2 diabetes, who often present with recalcitrant peripheral ulcers. The angiosome model of the foot presents an opportunity to perform direct angiosome-targeted endovascular interventions to maximise both wound healing and limb salvage. A systematic review was performed, with 17 studies included in the final review. Below-the-knee endovascular interventions present significant technical challenges, with technical success depending on the length of lesion being treated and the number of angiosomes that require treatment. Wound healing was significantly improved with direct angiosome-targeted angioplasty, as was limb salvage, with a significant increase in survival without major amputation. Indirect angioplasty, where the intervention is applied to collateral vessels to the angiosomes, yielded similar results to direct angiosome-targeted angioplasty. Applying the angiosome model of the foot in direct angiosome-targeted angioplasty improves outcomes for patients with recalcitrant diabetic foot ulcers in terms of primary wound healing, mean time for complete wound healing and major amputation-free survival.
