Ebbry-blastin'-theng ye needs must know-oo to lay tongue liker aargh-thentic pirate, by the devil's twisted tail. Take a tour through the world of piracy with the only authoritative work on the pirate language. A comprehensive course in pirate vocabulary, pronunciation, grammar, and syntax, The Pirate Primer contains three centuries of distinctive terms and usages uttered by (and attributed to) pirates in film, TV, literature, and history. Discover more than 100 pages of threats, curses, oaths, insults, and epithets; 31 types of pirate drink; 60 different pirate terms for ''woman''; 67 kinds of pirate torture and punishment; 44 distinct definitions of ''aargh''; and more. Each entry in the Primer is accompanied by an excerpt, so you can see the words and phrases used in proper context by actual pirates. And each linguistic concept is introduced by a related anecdote or narrative account, so you can live the language while you learn it. Whether you're simply fascinated by the culture of the Brethren of the Coast or you fancy yourself a modern-day corsair, The Pirate Primer is your guide to authentic pirate speak. Should you ever stare down Davy Jones and he demands proof that you're one who flies no flag, despair not. You'll be able to talk the talk, and no mistake.

Maritime piracy's improbable re-emergence following the end of the Cold War was surprising as the image of pirates evokes masted galleons and cutlasses. Yet, the number of incidents and their intensity skyrocketed in the 1990s and 2000s off of the coasts of Indonesia, Malaysia, the Philippines, India, Bangladesh, Nigeria, and Somalia. As Ursula Daxecker and Brandon Prins demonstrate in Pirate Lands, Maritime piracy-like civil war, terrorism, and organized crime-is a problem of weak states. Surprisingly, though, pirates do not operate in the least governed areas of weak states. Daxecker and Prins address this puzzle by explaining why some coastal communities experience more pirate attacks in their vicinity than others. They find that pirates do well in places where elites and law enforcement can be bribed, but they also need access to functioning roads, ports, and markets. Using statistical analyses of cross-national and sub-national data on pirate attacks in Indonesia, Nigeria, and Somalia, Daxecker and Prins detail how governance at the state and local level explain the location of maritime piracy. Additionally, they employ geo-spatial tools to rigorously measure how local political capacity and infrastructure affect maritime piracy. Drawing upon interviews with former pirates, community members, and maritime security experts, Pirate Lands offers the first comprehensive, social-scientific account of a phenomenon whose re-appearance after centuries of remission took almost everyone by surprise.

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.
