“A Leader Or A Teacher”: A Latent Theory Of Transformative Education In James Macgregor Burns’S Transforming-Transactional Leadership Paradigm, Evan Rw Dutmer

Interdisciplinary Journal of Leadership Studies

The purpose of this paper is to uncover a latent theory of transformative teaching and learning to be found in James MacGregor Burns’s account of transforming leadership and place it in interdisciplinary conversation with transformative education. The importance of this interdisciplinary exploration consists in this: Burns’s view that good leadership and good teaching are nearly indistinguishable has powerful implications that have been too little recognized. For, if right, teachers ought to view their work as exemplifying leadership (of a mutually beneficial, elevating sort); similarly, leaders across organizations ought to look to transformative teachers as paradigmatic models of good leadership. Expanding …

Beyond Charisma: A Critical Theory Perspective On Populist Leadership In A Post-Covid Age Of Crisis, Samuel Fianko-Ofori, Stephen Apolima

Interdisciplinary Journal of Leadership Studies

This paper argues that the digital communication environment has qualitatively transformed the dynamics of populist leadership, moving it beyond a reliance on personal charisma. While the affective bonds between leaders and followers—explored by classical theorists like Weber, Freud, and Adorno—are not new, their operation within the platformed public sphere marks a distinct shift. We introduce the concept of Affective Populist Leadership (APL) to conceptualize this shift. APL is a mode of leadership sustained through the strategic cultivation and digital amplification of collective emotions. It operates through three mutually reinforcing mechanisms: (1) the perpetual theatrical framing of politics as crisis, (2) …
