The Dark Pyramid: Unpacking the Multidimensional Nature of the Dark Side of Leadership

British Journal of Management, EarlyView.
Abstract The dark side of leadership has been employed as an umbrella term to cover an array of concepts typically concerned with the dysfunctionality and/or toxicity of individual leaders. As the field of leadership studies moves towards ‘post‐heroic’ perspectives, we apply the same ontological positioning, adopting a ‘post‐villainous’ perspective in ...

Desegregationist Pan‐African Spiritual Strivings: Du Bois, the Black Church and the Critique of Imperialism*

Journal of Religious History, EarlyView.
Abstract This article argues that W. E. B. Du Bois grounded his seminal conceptualisation of “the Negro church” in a Pan‐Africanist challenge to how Christian reformers and missionaries' usage of “Darkest Africa” as a metaphor for modern urban vice and poverty denigrated Africa and the African diaspora while promoting a segregated, imperialist version ...

Design and evaluation of metal oxide surge arrester parameters for lightning over voltages / Syahirah Abd. Halim [PDF]

, 2016
Surge arrester is widely used as a protective device to reduce possibility of flashover during transient overvoltage. It is important to understand the characteristics of surge arrester as over-specification of its rating will result in a reduction of ...
