With in-depth coverage of a wide range of issues, from terrorism, inter-state conflict, and nuclear deterrence to environmental security, health, and organized crime, Contemporary Security Studies is the definitive introduction to security studies. Bringing together leading scholars, it provides a student-friendly guide to traditional and critical theoretical approaches, as well the most important issues that dominate the modern security agenda. Throughout the text, students are encouraged to question their own preconceptions and to use their own judgement to critically evaluate key approaches and ideas. To help them achieve this, each chapter is punctuated with helpful learning features including 'key ideas', 'think points' and case studies, which demonstrate the real world applications, relevance, and implications of the theory.The book is supported by online resources designed to help students take their learning further. For students: - Explore relevant security issues in greater depth with additional online case studies.- Test your understanding of the key ideas and themes in each chapter with self-marking multiple-choice questions. - Expand your knowledge of the subject with web links to additional reliable sources. For registered lecturers: - Use the adaptable PowerPoint slides as the basis for lecture presentations, or as hand-outs in class.
