Electoral Strategies and Political Marketing


Book Description

Despite the central importance of elections to representative democracy, there is no systematic study available of how exactly the parties wage their election campaigns. Examining recent elections in nine countries across three continents, there case studies, all following a common framework, are written by national experts and are based on detailed interviewing and research of the parties. The book includes a lengthy introduction; a comparative study on campaign 'effects'; and a detailed conclusion.




Ceramic Materials and Components for Engines


Book Description

Several ceramic parts have already proven their suitability for serial application in automobile engines in very impressive ways, especially in Japan, the USA and in Germany. However, there is still a lack of economical quality assurance concepts. Recently, a new generation of ceramic components, for the use in energy, transportation and environment systems, has been developed. The efforts are more and more system oriented in this field. The only possibility to manage this complex issue in the future will be interdisciplinary cooperation. Chemists, physicists, material scientists, process engineers, mechanical engineers and engine manufacturers will have to cooperate in a more intensive way than ever before. The R&D activities are still concentrating on gas turbines and reciprocating engines, but also on brakes, bearings, fuel cells, batteries, filters, membranes, sensors and actuators as well as on shaping and cutting tools for low expense machining of ceramic components. This book summarizes the scientific papers of the 7th International Symposium "Ceramic Materials and Components for Engines". Some of the most fascinating new applications of ceramic meterials in energy, transportation and environment systems are presented. The proceedings shall lead to new ideas for interdisciplinary activities in the future.

Fire Retardancy of Polymeric Materials


Book Description

The third edition of Fire Retardancy of Polymeric Materials provides a single source for all aspects of this highly challenging field of applied research. This authoritative book covers design and non-fire requirements that drive how these materials are fire protected. Detailed study and consideration of chemistry, physics, materials science, economic issues and fire safety science is necessary to address considerations of mechanical, thermal, environmental, and end-use requirements on top of fire protection means that the field requires. This thoroughly revised new edition continues to offer comprehensive coverage of the scientific approach for those developing fire safe materials. It covers new topics such as bio-based materials, regulatory issues, recycling, newer flame retardant chemical classes, and more details on how to flame retard materials for specific market applications. Written by a team of experts, this book covers the fundamentals of polymer burning and combustion and how to apply fire protection or flame-retardant chemistries to specific material classes and applications. The book is written for material scientists and fire safety scientists who seek to develop new fire safe materials or understand why materials burn in our modern environment. Features Connects fundamentals of material flammability to practical fire safety needs Covers current fire safety requirements and regulations affecting flame retardant selection Provides information on chemical structure-property relationships for flame retardancy Provides practical guidance on how to design fire safe materials for specific fire risk scenarios The new edition is expanded to 32 chapters and all chapters are updated and revised with the newest information

Changing Parties


Book Description

Party conferences are central to the life of political parties. They contribute to setting policy agendas, developing policy options, legitimizing policy choices, building party cohesion, motivating activists and publicizing party activities to the wider public. An analysis of their evolution in Britain helps us understand the ways in which political parties change. This book combines anthropological methods with political science to analyze changing power relationships, party organizations and political culture in British political parties: Labour, Conservative, Liberal Democrats, The Greens.




The Soundscape of Modernity


Book Description

A vibrant history of acoustical technology and aural culture in early-twentieth-century America. In this history of aural culture in early-twentieth-century America, Emily Thompson charts dramatic transformations in what people heard and how they listened. What they heard was a new kind of sound that was the product of modern technology. They listened as newly critical consumers of aural commodities. By examining the technologies that produced this sound, as well as the culture that enthusiastically consumed it, Thompson recovers a lost dimension of the Machine Age and deepens our understanding of the experience of change that characterized the era. Reverberation equations, sound meters, microphones, and acoustical tiles were deployed in places as varied as Boston's Symphony Hall, New York's office skyscrapers, and the soundstages of Hollywood. The control provided by these technologies, however, was applied in ways that denied the particularity of place, and the diverse spaces of modern America began to sound alike as a universal new sound predominated. Although this sound—clear, direct, efficient, and nonreverberant—had little to say about the physical spaces in which it was produced, it speaks volumes about the culture that created it. By listening to it, Thompson constructs a compelling new account of the experience of modernity in America.




The Representative Claim


Book Description

Representation is more than a matter of elections and parties. This book offers a radical new perspective on the subject. Representation, it argues, is all around us, a dynamic practise across societies rather than simply a fixed feature of government. At the heart of the argument is the straightforward but versatile notion of the representative claim. People claim to speak or stand for others in multiple, shifting, and surprising patterns. At the same time they offer images of their constituents and audiences as artists paint portraits. Who can speak for and about us in this volatile world of representations? Which representative claims can have democratic legitimacy? The Representative Claim is set to transform our core assumptions about what representation is and can be. At a time when political representation is widely believed to be in crisis, the book provides a timely and critical corrective to conventional wisdom on the present and potential future of representative democracy.
