This book analyses the complex power dynamics and interpersonal politics that lie at the heart of leadership in professional organizations, such as accounting, law, and consulting firms, investment banks, hospitals, and universities. It is based on scholarly research into many of the world’s leading professional organizations across a range of sectors, including interviews with over 500 senior professionals in sixteen countries. Drawing on the latest academic theory to analyse exactly how professionals in organizations come together to create ‘leadership’, it provides new insights into how leaders lead when there is no traditional hierarchy to support them, their own authority is contingent, and they must constantly renegotiate relationships with relatively autonomous professional peers. It explores how leaders persuade highly intelligent, educated, and opinionated professionals to work together; how change happens within professional organizations; and why leaders so often fail. Part I introduces the concept of plural leadership, analysing how leaders establish and maintain their positions within leadership constellations, and the implications for governance in the context of collective or distributed leadership. Part II examines the complex, challenging relationships between professionals as they seek to influence their organizations, including the phenomena of leadership dyads, insecure overachievers, social control, and the rise of the management professional. Part III examines the shifts in the locus of power as professional organizations grow, adapt, and react to external stimuli such as mergers and acquisitions and economic crises. The conclusion identifies the paradoxes inherent in professional organizations and examines the role of leaders in attempting to reconcile them.

This paper deals with uncertainty, asymmetric information, and risk modelling in a complex power system. The uncertainty is managed by using probability and decision theory methods. More specifically, influence diagrams—as extended Bayesian network functions with interval probabilities represented through credal sets—were chosen for the predictive modelling scenario of replacing the most critical circuit breakers in optimal time. Namely, based on the available data on circuit breakers and other variables that affect the considered model of a complex power system, a group of experts was able to assess the situation using interval probabilities instead of crisp probabilities. Furthermore, the paper examines how the confidence interval width affects decision-making in this context and eliminates the information asymmetry of different experts. Based on the obtained results for each considered interval width separately on the action to be taken over the considered model in order to minimize the risk of the power system failure, it can be concluded that the proposed approach clearly indicates the advantages of using interval probability when making decisions in systems such as the one considered in this paper.

Research in fields such as multimodality and semiotics has focused on creation of value in different forms: aesthetic, economic and symbolic. However, the destruction of value has attracted much less attention. The aim of this article is to identify social, semiotic and ideological functions of acts of destruction based on an analysis of the traces these acts leave on the urban environment. Five overarching acts of destruction are discussed, but the authors’ main focus is on what they call transformation-driven and social presence-driven destruction, with two examples from Sweden and South Africa. The article discusses sanctioned destructive acts that are largely in compliance with dominating semiotic regimes at a certain time and place, as well as disruptive actions that challenge or even disobey those regimes. The analysis shows how a distinction between sanctioned and disruptive is in no way clear and often depends on complex power distributions between semiotic regimes at a given time and place. In fact, traces in the physical environment that may point to or index highly destructive acts can, in relation to other semiotic regimes, be regarded as creative and constructive. The authors argue that the semiotic processes of destruction and the traces they leave deserve more attention from research in the fields of multimodality and semiotics.
