Leader ship scholars and lay actors often attribute a certain presence to great leaders in describing a commanding style or a charismatic personality. However, leader ship presence and its mirror concept, absence, have been difficult concepts for researchers to study. This article proposes to redress this shortcoming using actor-network theory (ANT). In ANT, the focus is on human and nonhuman agents, their hybrid forms, networked social action, and macro acting, the latter of which enables leaders or followers to speak on behalf of their organizations. Together with ANT's emphasis on the role of narrative, this approach directs analysts to the situated construction of actor networks in which leader ship presence or absence is attributed. An emphasis on discourse also shows how various actants are imbued with meaning, enabling analysts to unravel networks and flows of power associated with leader ship presence/absence. Leader ship discourses involving charismatic/transformational leader ship are considered as well as the disaster management networking associated with two US Governors, Arnold Schwarzenegger and Kathleen Blanco, for their respective handling of the California wildfires and hurricane Katrina. In what measure should we attribute agency to nonhumans, how might we articulate their 'purposes', and how might we go about disentangling the autonomy of their impact from the discourses in which they are at once buoyed and constructed? These are horrible questions -but taking a different tack, we might say that these very questions are what should be addressed in relation to human actors. (Michael, 1996: 24) Conventional wisdom has it that great leaders have 'a certain presence' about them. Yet, such a description usually says more about an elusive, ephemeral effect that a leader produces than on specific actions performed or conditions that exist. Leadership scholars and lay actors also attribute presence to great leaders usually as they try to characterize one or more features of a charismatic personality or effective command in crises situations (Conger
