Throughout his life Lewis Fry Richardson made many inspirational contributions to various disciplines by building mathematical models to solve problems where others had found mathematical models difficult to find. Collected in this first volume are many of Richardson's papers covering the mathematical and physical sciences.

This is an open access book. Lewis F Richardson (1981-1953), a physicist by training, was a pioneer in meteorology and peace research and remains a towering presence in both fields. This edited volume reviews his work and assesses its influence in the social sciences, notably his work on arms races and their consequences, mathematical models, the size distribution of wars, and geographical features of conflict. It contains brief bibliographies of his main publications and of articles and books written about Richardson and his work and discusses his continuing influence in peace research and international relations as well as his attitude to the ethical responsibilities of a scientist. It will be of interest to a wide range of scholars. This book includes 11 chapters written by Nils Petter Gleditsch, Dina A Zinnes, Ron Smith, Paul F Diehl, Kelly Kadera, Mark Crescenzi, Michael D Ward, Kristian Skrede Gleditsch, Nils B Weidmann, Jürgen Scheffran, Niall MacKay, Aaron Clauset, Michael Spagat and Stijn van Weezel. Lewis F Richardson occupied an important position in two academic fields as different as meteorology and peace research, with academic prizes awarded in both disciplines. In peace research, he pioneered the use of mathematical models and the meticulous compilation of databases for empirical research. As a quaker and pacifist, he refused to work in preparations for war, paid a heavy prize in terms of his career, and (at least in the social sciences) was fully recognized as a pioneering scholar only posthumously with the publication of two major books. Lewis Fry Richardson is one of the 20th century’s greatest but least appreciated thinkers—a creative physicist, psychologist, meteorologist, applied mathematician, historian, pacifist, statistician, and witty stylist. If you’ve heard of weather prediction, chaos, fractals, cliometrics, peace science, big data, thick tails, or black swans, then you have benefited from Richardson’s prescience in bringing unruly phenomena into the ambit of scientific understanding. Richardson’s ideas continue to be relevant today, and this collection is a superb retrospective on this brilliant and lovable man.

How does regional interdependence influence the prospects for conflict, integration, and democratization? Some researchers look at the international system at large and disregard the enormous regional variations. Others take the concept of sovereignty literally and treat each nation-state as fully independent. Kristian Skrede Gleditsch looks at disparate zones in the international system to see how conflict, integration, and democracy have clustered over time and space. He argues that the most interesting aspects of international politics are regional rather than fully global or exclusively national. Differences in the local context of interaction influence states' international behavior as well as their domestic attributes. In All International Politics Is Local, Gleditsch clarifies that isolating the domestic processes within countries cannot account for the observed variation in distribution of political democracy over time and space, and that the likelihood of transitions is strongly related to changes in neighboring countries and the prior history of the regional context. Finally, he demonstrates how spatial and statistical techniques can be used to address regional interdependence among actors and its implications. Kristian Skrede Gleditsch is Assistant Professor of Political Science at the University of California, San Diego.

This new book introduces innovative research on democracy from the leading Comparative Manifestos Project (CMP). It details the key achievements of the project to date, illustrates how its findings may be applied, lays out the future challenges it faces and examines how the field as a whole can advance. It also presents a special assessment of the dimensionality of party competition, presenting ways in which research can be extended and related to broader approaches in Political Science and Theory. Although CMP research is widely used and constitutes the major comparative data set on party positions and ideological location, it is also subject to challenge. The volume therefore provides the reader with a clear sense of the key debates and questions surrounding its work. This volume also honours the life-time achievement of Professor Ian Budge, who has provided distinguished intellectual leadership for the CMP over the last twenty-five years. This is an essential point of reference for all comparative research on the functioning of democracies. This book will be of great interest to all students and scholars of politics and of democracy in particular.

A world model: economies, trade, migration, security and development aid. This bookprovides the analytical capability to understand and explore the dynamics of globalisation. It is anchored in economic input-output models of over 200 countries and their relationships through trade, migration, security and development aid. The tools of complexity science are brought to bear and mathematical and computer models are developed both for the elements and for an integrated whole. Models are developed at a variety of scales ranging from the global and international trade through a European model of inter-sub-regional migration to piracy in the Gulf and the London riots of 2011. The models embrace the changing technology of international shipping, the impacts of migration on economic development along with changing patterns of military expenditure and development aid. A unique contribution is the level of spatial disaggregation which presents each of 200+ countries and their mutual interdependencies – along with some finer scale analyses of cities and regions. This is the first global model which offers this depth of detail with fully work-out models, these provide tools for policy making at national, European and global scales. Global dynamics: Presents in depth models of global dynamics. Provides a world economic model of 200+ countries and their interactions through trade, migration, security and development aid. Provides pointers to the deployment of analytical capability through modelling in policy development. Features a variety of models that constitute a formidable toolkit for analysis and policy development. Offers a demonstration of the practicalities of complexity science concepts. This book is for practitioners and policy analysts as well as those interested in mathematical model building and complexity science as well as advanced undergraduate and postgraduate level students.

Geo-mathematical modelling: models from complexity science Sir Alan Wilson, Centre for Advanced Spatial Analysis, University College London Mathematical and computer models for a complexity science tool kit Geographical systems are characterised by locations, activities at locations, interactions between them and the infrastructures that carry these activities and flows. They can be described at a great variety of scales, from individuals and organisations to countries. Our understanding, often partial, of these entities, and in many cases this understanding is represented in theories and associated mathematical models. In this book, the main examples are models that represent elements of the global system covering such topics as trade, migration, security and development aid together with examples at finer scales. This provides an effective toolkit that can not only be applied to global systems, but more widely in the modelling of complex systems. All complex systems involve nonlinearities involving path dependence and the possibility of phase changes and this makes the mathematical aspects particularly interesting. It is through these mechanisms that new structures can be seen to ‘emerge’, and hence the current notion of ‘emergent behaviour’. The range of models demonstrated include account-based models and biproportional fitting, structural dynamics, space-time statistical analysis, real-time response models, Lotka-Volterra models representing ‘war’, agent-based models, epidemiology and reaction-diffusion approaches, game theory, network models and finally, integrated models. Geo-mathematical modelling: Presents mathematical models with spatial dimensions. Provides representations of path dependence and phase changes. Illustrates complexity science using models of trade, migration, security and development aid. Demonstrates how generic models from the complexity science tool kit can each be applied in a variety of situations This book is for practitioners and researchers in applied mathematics, geography, economics, and interdisciplinary fields such as regional science and complexity science. It can also be used as the basis of a modelling course for postgraduate students.

This energetic and thought-provoking book encourages a reflexive, non-nationalistic approach to doing world research and sets out how to understand, plan, do and use this research. Williams introduces a range of frameworks, from desk-based studies and traditional ethnography to the use of internet, satellites, robots, drones and ‘big data’, and provides exciting, interdisciplinary examples. This book is presented in a clear international style and uses creative approaches to researching peoples, places and world systems. It explains: desk-based research using international data including documentaries, museum objects, archives, data-sets and working with groups such as refugees, tourists and migrants distance research using online videos, surveys and remote methods such as video conferencing and crowdsourcing fieldwork abroad, including ethnography, street observation and mapping. The book is also accompanied by a website, with the following features: For Students Weblinks for each chapter Examples/summaries/templates related to text marked with Additional thinking zones An overview of data capture technologies For Lecturers Copies of all the figures and thinking zones for use in teaching material PowerPoint slides for each chapter Built upon the foundations of the author’s 30 years of research experience, and including original case studies from international students, this is an essential guide for anyone in the social sciences using or doing international and global research.

How do you define good mental health? This controversial, counterintuitive, and altogether fascinating book argues that "psychological normality" is neither a desirable nor an acceptable standard. Normality Does Not Equal Mental Health: The Need to Look Elsewhere for Standards of Good Psychological Health is a groundbreaking work, the first book-length study to question the equation of psychological normality and mental health. Its author, Dr. Steven James Bartlett, musters compelling evidence and careful analysis to challenge the paradigm accepted by mental health theorists and practitioners, a paradigm that is not only wrong, but can be damaging to those to whom it is applied—and to society as a whole. In this bold, multidisciplinary work, Bartlett critiques the presumed standard of normality that permeates contemporary consciousness. Showing that the current concept of mental illness is fundamentally unacceptable because it is scientifically unfounded and the result of flawed thinking, he argues that adherence to the gold standard of psychological normality leads to nothing less than cultural impoverishment.

Utility is a key concept in the economics of individual decision-making. However, utility is not measurable in a straightforward way. As a result, from the very beginning there has been debates about the meaning of utility as well as how to measure it. This book is an innovative investigation of how these arguments changed over time. Measuring Utility reconstructs economists' ideas and discussions about utility measurement from 1870 to 1985, as well as their attempts to measure utility empirically. The book brings into focus the interplay between the evolution of utility analysis, economists' ideas about utility measurement, and their conception of what measurement in general means. It also explores the relationships between the history of utility measurement in economics, the history of the measurement of sensations in psychology, and the history of measurement theory in general. Finally, the book discusses some methodological problems related to utility measurement, such as the epistemological status of the utility concept and its measures. The first part covers the period 1870-1910, and discusses the issue of utility measurement in the theories of Jevons, Menger, Walras and other early utility theorists. Part II deals with the emergence of the notions of ordinal and cardinal utility during the period 1900-1945, and discusses two early attempts to give an empirical content to the notion of utility. Part III focuses on the 1945-1955 debate on utility measurement that was originated by von Neumann and Morgenstern's expected utility theory (EUT). Part IV reconstructs the experimental attempts to measure the utility of money between 1950 and 1985 within the framework provided by EUT. This historical and epistemological overview provides keen insights into current debates about rational choice theory and behavioral economics in the theory of individual decision-making and the philosophy of economics.
