This book addresses the question of how the properties of human vowel systems can be explained. Though it is found that vowel systems of human languages are optimal for communicative purposes, it is not clear who is doing the optimization. If children learn a language, they learn to produce sounds that are as close as possible to those used by their parents and peers. The hypothesis is put forward that the optimization is the result of self-organization in a population of language users. Self-organization is the emergence of order on a global scale in a system where there are only local interactions. It is a phenomenon that appears in many natural systems from purely physical ones, such as crystals, to systems composed of living organisms, such as colonies of insects. Recent developments in linguistics indicate that self-organization might also play an important role in language.The theory is put to the test by implementing it as a computer model. This computer model simulates the interaction in a population of artificial 'agents' that can each produce and perceive vowels in a human-like way. The vowel systems that emerge from the computer simulations closely resemble human vowel systems. It is also shown that many simple variations on the basic system can be investigated, thus providing valuable insight into the dynamics of systems of speech sounds.The ultimate aim of the book is to provide insight into how language has evolved. It turns out that the mechanism of self-organization can make it easier to explain the evolution of language, since it provides an alternative mechanism for the emergence of certain linguistic structures.

A comprehensive field guide covering the birds of the Dutch Caribbean.Located in the southern Caribbean off the coast of Venezuela, the constituent countries of Aruba and Curaçao and the special municipality of Bonaire along with some smaller islands are popular tourist destinations. They are also home to a fine selection of Caribbean specialities, such as Brown-throated Parakeet, Venezuelan Troupial, Roseate Spoonbill and White-tailed Nightjar, while migrant hotspots on the islands can be exceptional. This field guide is designed to help you identify the many wonderful birds that live in this part of the western Lesser Antilles. It features 71 colour plates, with facing text describing key identification features, voice, habitat, behaviour and status of every species known to occur on the islands.This compact yet comprehensive guide is an important addition to the suitcase for any visiting wildlife traveller or birder on these beautiful islands.
