The dynamics of many nonlinear systems gravitate around a few common central themes: intermittency, order/coherence and disorder. These features affect scalings and lead to deviations from Gaussian behaviour. Intermittency may be the universal outcome of a large class of nonlinear systems; however the universality properties of specific nonlinear systems, that is the dependencies of the intermittent structure on initial and boundary conditions, remain open questions. This volume consists of articles by prominent figures who all participated in a workshop held at the Newton Institute in Cambridge. It reflects the aims of the workshop, namely to capture and summarise recent developments, encourage cross-fertilisation of ideas, lay out research directions for the future and provide an overview of our current understanding of the subject.
