Book Description
This book is designed to provide students of phonology with an accessible introduction to the phonological architecture of words. It offers a thorough discussion of the basic building blocks of phonology - in particular features, sounds, syllables and feet - and deals with a range of different theories about these units. Colin Ewen and Harry van der Hulst present their study within a non-linear framework, discussing the contributions of autosegmental phonology, dependency phonology, government phonology and metrical phonology, among others. Their coherent, integrated approach reveals that the differences between these models are not as great as is sometimes believed. The book provides a more detailed analysis of this subject than previously available in introductory textbooks and is an invaluable and indispensable first step towards understanding the major theoretical issues in modern phonology at the word level.

Book Description
This edited collection is an interdisciplinary study of gems in the early modern world. It examines the relations between the art, science, and technology of gems, and it does so against the backdrop of an expanding global trade in gems. The eleven chapters are organised into three parts. The first part sets the scene by describing how gems moved around the early modern world, how they were set in motion, and how they were pulled together in the course of their travels. The second part is about value. It asks why people valued gems, how they determined the value of a given gem, and how the value of a gem was connected to its perceived place of origin. The third part deals with the skills involved in cutting, polishing, and mounting gems, and how these skills were transmitted and articulated by artisans. The common themes of all these chapters are materials, knowledge and global trade. The contributors to this volume focus on the material properties of gems such as their weight and hardness, on the knowledge involved in exchanging them and valuing them, and on the cultural consequences of the expanding trade in gems in Eurasia and the Americas.

Book Description
The Structures of Practical Knowledge investigates the nature of practical knowledge – why, how, when and by whom it is codified, and once codified, how this knowledge is structured. The inquiry unfolds in a series of fifteen case studies, which range in focus from early modern Italy to eighteenth century China. At the heart of each study is a shared definition of practical knowledge, that is, knowledge needed to obtain a certain outcome, whether that be an artistic or mechanical artifact, a healing practice, or a mathematical result. While the content of practical knowledge is widely variable, this study shows that all practical knowledge is formally equivalent in following a defined workflow, as reflected in a construction procedure, a recipe, or an algorithm. As explored in the volume’s fifteen contributions, there are three levels at which structures of practical knowledge may be understood and examined. At the most immediate level, there are the individual workflows that encompasses practical knowledge itself. Probing further, it is possible to examine the structure of practical knowledge as it is externalized and codified in texts, drawings, and artifacts such as models. Finally, practical knowledge is also related to social structures, which fundamentally determine its dissemination and evolution into new knowledge structures. The social structures of professionals and institutions represent the critical means by which practical knowledge takes form. These actors are the agents of codification, and by means of selection, appropriation, investment, and knowledge development, they determine the formation of new structures of practical knowledge. On a more abstract level, the creation of new knowledge structures is understood as constituting the basis for the further development of scientific knowledge. Rich in subject matter and incisive in the theory it lays out, this volume represents an important contribution to the history of science and epistemology. Individually, the fifteen case studies – encompassing the history of architecture, mining, brewing, glass production, printing, ballistics, mechanics, cartography, cosmology and astronomy – are replete with original research, and offer new insights into the history of science. Taken together, the contributions remodel historical epistemology as a whole, elucidating the underlining knowledge structures that transcend disciplinary boundaries, and that unite practitioners across time and space.

Book Description
Today, climate-related processes and problems are referred to as Global Change by nearly everyone including scientists, politicians, and economists; citizens worldwide are anxious about the often ob served disorientation of our environment under the influence of man. Better information on the Earth's natural systems and their possible alterations is necessary. The topic itself is so wide that sound scien tific descriptions of it as a whole are rare. For the non-specialist infor mation from relevant fields is not easy to obtain; and often, the pro gnostic models presented are contradictory and even for specialists difficult to evaluate. Therefore, this book on Climate, Earth Processes and Earth History by Richard Huggett fills an important gap. It discusses the great, climate-related areas of the Earth's environment. The atmosphere, the hydrosphere, the sediments as products of weathering and geomorphic processes, the relief as landforms and soils, and the biosphere are thoroughly treated as the prominent sub systems which are greatly affected by climate. These subsystems not only control the visual and internal aspects of our landscapes, but they are themselves especially influenced by climatic changes which can be due to either changes in the natural system or anthropogenic changes. Thus, our landscapes will be subject to significant altera tions, if climatic variations exceed certain thresholds. The plan for the present book by Richard Huggett was originally discussed in regard to the Springer Series on Physical Environment.
