Discussing, defining and engaging with 'terrorism' has long been limited to the narrowly framed situations in which parties to an asymmetric conflict resort to the use of force and to the legitimacy they have in doing so. The problem with the limited understanding of 'terrorism' and 'counterterrorism' as 'facts of objective reality' is the lack of attention to the role of the extreme asymmetry of power in conflicts involving 'terrorism' that does not lend itself to analysis readily. This thesis introduces a new theoretical concept, the Terrorism Complex that signifies the complexity of power/knowledge relations and the complexity of power/knowledge practices that operate on a discursive and non-discursive level through time and are affected by the mechanisms of power that stem from the asymmetry of power between the actors involved in a conflict. The research into the Terrorism Complex involves an ontological and epistemological widening of the research focus to account for these effects of the interplay between power and knowledge on the production, construction and perception of 'terrorism'. I draw on postmodern scholarship and the Critical Terrorism Studies to present a theoretical and methodological framework that is used to examine the production of knowledge in relation to the asymmetries of power. The Israeli–Palestinian conflict is used as a case study for the study of power asymmetry in the political field that determines who will be labelled a 'terrorist' and who will be able to claim the moral high ground. The research also reveals the surprising extent to which the power over discourse obscures the role of the systemic terrorising exercise of state power in inducing 'terrorism'. The final chapter concentrates on the media's role in the Terrorism Complex. It applies the findings from other chapters to observe the Terrorism Complex in action. ; The Leverhulme Trust

Persistence is an important characteristic of many complex systems in nature, related to how long the system remains at a certain state before changing to a different one. The study of complex systems' persistence involves different definitions and uses different techniques, depending on whether short-term or long-term persistence is considered. In this paper we discuss the most important definitions, concepts, methods, literature and latest results on persistence in complex systems. Firstly, the most used definitions of persistence in short-term and long-term cases are presented. The most relevant methods to characterize persistence are then discussed in both cases. A complete literature review is also carried out. We also present and discuss some relevant results on persistence, and give empirical evidence of performance in different detailed case studies, for both short-term and long-term persistence. A perspective on the future of persistence concludes the work. ; This research has been partially supported by the project PID2020-115454GB-C21 of the Spanish Ministry of Science and Innovation (MICINN).

AbstractThis paper presents an inter‐level causal view of complex systems. It argues the need to go beyond causal reductionism, the limitations of the model of theory reduction in understanding and explaining the behaviour of complex systems, and the incompleteness of individualism methodology in explaining complex social organizational behaviours. It proposes a multi‐level and multi‐dimensional co‐evolutionary 'complex holism' to provide a new prospective for understanding organizational evolution and management.

Kaye Remington's Leading Complex Projects draws on original, empirical research into leadership of complex projects across a broad range of industries. The book explains and applies emerging best-practice in a coherent and focused way. It will inform experienced practitioners and well as those involved in teaching and researching projects, complexity and leadership.

▪ Abstract  The study of complex adaptive systems, a subset of nonlinear dynamical systems, has recently become a major focus of interdisciplinary research in the social and natural sciences. Nonlinear systems are ubiquitous; as mathematician Stanislaw Ulam observed, to speak of "nonlinear science" is like calling zoology the study of "nonelephant animals" (quoted in Campbell et al. 1985 , p. 374). The initial phase of research on nonlinear systems focused on deterministic chaos, but more recent studies have investigated the properties of self-organizing systems or anti-chaos. For mathematicians and physicists, the biggest surprise is that complexity lurks within extremely simple systems. For biologists, it is the idea that natural selection is not the sole source of order in the biological world. In the social sciences, it is suggested that emergence—the idea that complex global patterns with new properties can emerge from local interactions—could have a comparable impact.
