This book treats bounded arithmetic and propositional proof complexity from the point of view of computational complexity. The first seven chapters include the necessary logical background for the material and are suitable for a graduate course. Associated with each of many complexity classes are both a two-sorted predicate calculus theory, with induction restricted to concepts in the class, and a propositional proof system. The complexity classes range from AC0 for the weakest theory up to the polynomial hierarchy. Each bounded theorem in a theory translates into a family of (quantified) propositional tautologies with polynomial size proofs in the corresponding proof system. The theory proves the soundness of the associated proof system. The result is a uniform treatment of many systems in the literature, including Buss's theories for the polynomial hierarchy and many disparate systems for complexity classes such as AC0, AC0(m), TC0, NC1, L, NL, NC, and P.

A New Era of U.S.-Vietnam Relations examines the history of the relationship and offers concrete recommendations for policymakers in both countries to deepen cooperation across each major area of the relationship: political and security ties, trade and economic linkages, and people-to-people connections.

The South China Sea is arguably one of the world’s most dangerous regions, with conflicting diplomatic, legal, and security claims by major and mid-level powers. To assess these disputes, CSIS brought together an international group of experts—from Australia, Canada, China, Indonesia, Japan, Malaysia, the Philippines, the United Kingdom, the United States, and Vietnam. This volume gathers these experts’ analyses to provide a diverse and wide-ranging set of perspectives on the region and to explore possibilities for future cooperation.

Building on a careful analysis of Southeast Asia’s recent history, politics, economics, and place within the Asia Pacific, this report looks forward two decades to anticipate the development of trends in the region and how they will impact the U.S.-Japan alliance. How will Southeast Asian states come to grips with the political and economic rise of China? How will they modernize their military forces and security relationships, and what role can the United States and Japan play? How will they manage their disputes in the South China Sea, and how will they pursue greater regional integration? These questions will prove critical in understanding Southeast Asia’s role in the Asia Pacific, and in the U.S.-Japan alliance, in the decades ahead.

With elections in both the Philippines and the United States in 2016, the future of the alliance must be institutionalized to ensure that it is not diminished by a change of leadership in either country. A new Enhanced Defense Cooperation Agreement and cooperation in the South China Sea are important components of the new era of relations, but they are not and should not be the only defining features of the alliance. Given the long history of U.S.-Philippine relations, the alliance must be based on more robust cooperation across the spectrum of political, security, economic, and sociocultural relations. Security concerns provide an acute impetus for leaders to put more energy into the relationship, but its sustainability will require a more comprehensive focus.

The Center for Strategic and International Studies (CSIS) hosted its fifth annual South China Sea conference in July 2015. This compilation features papers from some of the top experts in the United States and Asia, who presented during the day’s panels. Bill Hayton, Bonnie Glaser, and Wu Shicun discuss recent developments in the South China Sea; Pham Lan Dung and Tran Huu Duy Minh explore legal issues surrounding the disputes; and Ian Storey, Patrick Cronin, Renato Cruz de Castro, and Peter Jennings examine various aspects of the military balance and regional order.

In 2014, the CSIS Europe and Southeast Asia Programs embarked on a two-year initiative to create a new and enduring EU-U.S. collaborative mechanism to enhance transatlantic Asia-Pacific policy coordination and understanding. This report is the culmination of this two-year study and presents the findings of the research while also offering actionable recommendations for U.S. and EU policymakers.

Extreme Violence: Understanding and Protecting People from Active Assailants, Hate Crimes, and Terrorist Attacks provides readers with a comprehensive treatment of critical knowledge needed to understand, prevent, prepare for, and respond to catastrophic acts of violence. In Part One of the book, readers learn about various types of extreme violence, terrorist organizations, attack methodologies, weapon types, mass transit targeting, and vulnerabilities of critical infrastructures. Part Two focuses on prevention strategies, including hazard and vulnerability assessments, evaluating anonymous threats, target-hardening, crime prevention through environmental design, security technology, and behavioral approaches. It also discusses how attackers can leverage an organization's own security technologies to carry out more effective attacks. Part Three explores preparedness and emergency responses, emergency communication systems, and the National Incident Management System. Part Four speaks to the aftermath of extreme violence by addressing public communications, mental health recovery measures, litigation and reputation damage protection, business resilience, and conducting post-incident reviews.Written by internationally experienced security experts who have helped prevent, respond to, and provide post-incident assistance for more than 32 planned attacks globally, Extreme Violence is an ideal resource for courses in security management, homeland security, terrorism, public administration, and law enforcement. This timely text is invaluable for practitioners working in homeland security, emergency management, policing, security, criminal justice, public administration, and terrorism.
