Although multifractals are rooted in probability, much of the related literature comes from the physics and mathematics arena. Multifractals: Theory and Applications pulls together ideas from both these areas using a language that makes them accessible and useful to statistical scientists. It provides a framework, in particular, for the evaluation of statistical properties of estimates of the Renyi fractal dimensions.The first section provides introductory material and different definitions of a multifractal measure. The author then examines some of the various constructions for describing multifractal measures. Building from the theory of large deviations, he focuses on constructions based on lattice coverings, covering by point-centered spheres, and cascades processes. The final section presents estimators of Renyi dimensions of integer order two and greater and discusses their properties. It also explores various applications of dimension estimation and provides a detailed case study of spatial point patterns of earthquake locations.Estimating fractal dimensions holds particular value in studies of nonlinear dynamical systems, time series, and spatial point patterns. With its careful yet practical blend of multifractals, estimation methods, and case studies, Multifractals: Theory and Applications provides a unique opportunity to explore the estimation methods from a statistical perspective.

Drawing on expert contributions from around the UK, this collection brings together a series of insights into the contemporary local and community news media landscape in the UK. Offering an analysis of the ongoing ‘crisis’ in the provision of local news, exacerbated by the COVID-19 pandemic, the book provides a critical space for practitioners and scholars to reflect on emerging models for economically sustainable, participatory local news services. It showcases new scholarly analyses of local news provision and community news practices, giving voice to the experiences of practitioners from across the local news ecology. In a set of diverse contributing chapters, campaigners and practitioners map out the period of recent rapid change for local news, questioning contemporary government initiatives and highlighting the advent of diverse, entrepreneurial reactions to the spaces created by a decline in local mainstream news services. This book is a timely examination of what we can learn from the variety of approaches being taken across the local media landscape in the commercial, subsidised and non-profit sector, shining new light on how practices that place the engagement of citizens at their centre might be propagated within this policy and funding landscape.Reappraising Local and Community News in the UK is a valuable resource for students and scholars interested in local news and journalism, as well as for anyone interested in the evolving local media landscape in the UK.

In the wake of the withdrawal of commercial journalism from local communities at the beginning of the 21st century, Hyperlocal Journalism critically explores the development of citizen-led community news operations. The book draws together a wide range of original research by way of case studies, interviews, and industry and policy analysis, to give a complete view of what is happening to communities as their local newspapers close or go into decline to be replaced by emerging forms of digital news provision. This study takes the United Kingdom as its focus but its findings speak to common issues found in local media systems in other Western democracies. The authors investigate who is producing hyperlocal news and why, as well as production practices, models of community and participatory journalism, and the economics of hyperlocal operations. Looking holistically at hyperlocal news, Hyperlocal Journalism paints a vivid picture of citizens creating their own news services via social media and on free blogging platforms to hold power to account, redress negative reputational geographies, and to tell everyday stories of community life. The book also raises key questions about the sustainability of such endeavours in the face of optimism from commentators and policy-makers.
