This book presents the essential ideas of coherent states and provides researchers and graduate students with the necessary tools for various applications of generalized coherent state theory. These applications include areas such as quantum information, quantum phase transitions, quantum many-body systems, quantum chaos, and quantum open systems. The aim of the book is to show how coherent states can be applied to an extensive range of physical systems. The authors provide many exercises at the end of each chapter to enhance the mastery of the subject. Throughout the first seven chapters, only an understanding of elementary quantum mechanics is assumed, and for the last six chapters, some basic knowledge of group theory is requested to follow the arguments. 

This book examines how media can be used in facilitating crisis control following natural disasters. Set in the context of the contemporary Chinese nationalistic culture this book dissects how Chinese media enhances disaster relief by constructing the meaning of it. It takes a historical overview of the negotiations between discursive power and media coverage of natural disasters in Chinese media. It then conducts a case study of the 2008 Wenchuan earthquake to analyze how Chinese media enhance crisis control in engaging with contemporary Chinese nationalism. In examining the mediated disaster relief closely relevant to this study within a global context this book briefly analyzes the Australian media's representation of the 2013 Tasmanian Bushfire. In a penetrating investigation of the research question a systematic theoretic framework is structured consisting of the theories of representation, discourse and power, cultural identity, media framing and narratives.
