Organic Representation as a Critical Media Approach to Leadership Studies in Popular Culture

New Directions for Student Leadership, Volume 2025, Issue 185, Page 75-80, Spring 2025.
ABSTRACT This article applies the critical media concept of organic representation to leadership studies as an analytic of how various creators in popular culture today are not just writing inclusive storytelling but, more notably, modeling new modes of production and self‐presentation that are actively challenging hegemonic industry practices and ...

Fair weather induced charges and currents on tall wind turbines and experiments with kites [PDF]

, 2016
Earth’s atmospheric potential rapidly increases up to few tens of kilovolts below 200 m altitude. This potential drop will induce charge to tall objects at ground by virtue of electrostatic induction.
