The so-called 'hard' or 'exact' sciences, with their necessary emphasis on technology and on the technical, are hardly reputed for being very human, and, conversely, the so-called 'human' sciences are often pronounced as 'soft' because they cannot be based on the certainties associated with the former. The search for truth - which is the essential dimension of the construction of a peaceful world - therefore has to navigate between considerations of a philosophical nature and the concrete data of the hard sciences. If, ever since the humanism of the Renaissance period, we have been happy to lay claim to the wisdom of one of its great writers, Rabelais, who taught a moral lesson to the young Pantagruel with the neat formula 'science without conscience is the ruin of the soul', we nonetheless stand in awe before modern scientific advances and the extraordinary achievements that they have opened up. If everything is not permissible, at least everything seems possible!

This textbook provides an overview of qualitive and quantitative methods used in different social sciences to investigate defence issues. Recently, defence issues have become of increasing interest to researchers in the social sciences, but they raise specific methodological questions. This volume intends to fill a gap in the literature on defence studies by addressing a number of topics not dealt with sufficiently before. The contributors offer a range of methodological reflections and tools from various social sciences (political science, sociology, geography, history, economics and public law) for researching defence issues. They also address the increasingly important question of data and digitalization. The book introduces the added value of quantitative and qualitative methods, and calls for a cross-fertilization of methods in order to facilitate better research on defence topics and to fully grasp the complexity of defence in the 21st century. This book will be of much interest to students, researchers and practitioners of defence studies, war studies, military studies, and social science research methods in general.

Ever since Thucydides pondered reasons for the outbreak of the Peloponnesian War, writers, philosophers, and social scientists have tried to identify factors that promote conflict escalation: for example, history (tomorrow's wars are often rooted in yesterday's conflicts), changing balance of power among nations, or domestic political forces. In the end, however, these "causes" are constructed by human beings and involve the memories, emotions, and motives of both the leaders and the led. In July 1914, the long-standing peace of Europe was shattered when the Sarajevo assassinations quickly escalated to World War I. In contrast, at the height of the Cold War, the Cuban Missile Crisis could have easily plunged the world into a thermonuclear world war, but was ultimately peacefully resolved. Why the different outcomes? In Roots of War: Wanting Power, Seeing Threat, Justifying Force, David G. Winter identifies three psychological factors that contributed to the differences in these historical outcomes: the desire for power, exaggerated perception of the opponent's threat, and justification for using military force. Several lines of research establish how these factors lead to escalation and war: comparative archival studies of "war" and "peace" crises, laboratory experiments on threat perception, and surveys of factors leading people to believe that a particular war is "just." The research findings in Roots of War also demonstrate the importance of power in preserving peace through diplomatic interventions, past and present.

This book gives a compelling analysis and explanation of shifts in China’s non-intervention policy in Africa. Systematically connecting the neoclassical realist theoretical logic with an empirical analysis of China’s intervention in African civil wars, the volume highlights a methodical interlink between theoretical and empirical analysis that takes into consideration the changing status of rising powers in the global system and its effect on their intervention behaviour. Based on field research and expert interviews, it provides a rigorous analysis of China’s emergent intervention behaviour in some key African conflicts in Libya, South Sudan and Mali and broadens the study of external interventions in civil wars to include the intervention behaviour of non-Western rising powers. Obert Hodzi is Visiting Researcher at the African Studies Center, Boston University, USA, and Postdoctoral Researcher at the University of Helsinki, Finland.

"Data is emerging as a key component of military operations, both on and off the battlefield. Large troves of data generated by new information technologies-often termed "big data"-are growing ever more important to a range of military functions. Military forces and other actors will increasingly need to acquire, evaluate, and utilize such data in many combat contexts. At the same time, those forces can gain advantages by targeting adversaries' data and data systems. And a multitude of actors within armed conflict, including humanitarian and human rights organizations, can also use big data to deliver aid or identify atrocities. Such myriad uses of big data raise challenging interpretive questions under international humanitarian law (IHL), the jus ad bellum, and international human rights law. This book is the first of its kind to examine how these bodies of international law might apply to the uses of big data specifically. Focusing on IHL, the book also assesses how jus ad bellum categories might translate to operations involving big data below the armed conflict threshold. And because big data is profoundly transforming modern life off the battlefield as well, the book explores questions beyond the role of big data within weapons systems and other military capabilities to questions about the nature of civilian harm and scope of individual rights. This book offers a range of approaches and ideas to this timely issue, and offers an initial roadmap for scholars, policymakers, and advocates to follow as they address the challenges still to come"--

This book provides a broad overview of what peace research is all about by an author who has been involved in the field for more than half a century. Among other things it gives a unique review of how peace research emerged in Sweden as the author was a key actor in the most crucial events during this formative period. The book also portrays how the discipline has grown from an initial focus on “alternatives to war” to the comprehensive study of the many dimensions of a “lasting and positive peace”. The author's own work covers causes of war, sanctions, conflict resolution, conflict data, mediation, and quality peace. They demonstrate the range of topics that have to be understood for a peace with quality. This is exemplified by some of the author's writings specifically selected for this volume plus a few ones original to it. Some accounts of the author's involvements in actual peace processes in the 1990s are also included. This publication offers a substantial contribution to understanding the evolution of peace research as a field and is an important reading for scholars, policy makers, journalists, students and any aspiring peace researcher as well as for the public at large. • Peter Wallensteen is a global pioneer of peace research due to his involvement in the creation of the Department of Peace and Conflict Research at Uppsala University ¬– a major center in the field.

How a new understanding of warfare can help the military fight today’s conflicts more effectively The way wars are fought has changed starkly over the past sixty years. International military campaigns used to play out between large armies at central fronts. Today's conflicts find major powers facing rebel insurgencies that deploy elusive methods, from improvised explosives to terrorist attacks. Small Wars, Big Data presents a transformative understanding of these contemporary confrontations and how they should be fought. The authors show that a revolution in the study of conflict--enabled by vast data, rich qualitative evidence, and modern methods—yields new insights into terrorism, civil wars, and foreign interventions. Modern warfare is not about struggles over territory but over people; civilians—and the information they might choose to provide—can turn the tide at critical junctures. The authors draw practical lessons from the past two decades of conflict in locations ranging from Latin America and the Middle East to Central and Southeast Asia. Building an information-centric understanding of insurgencies, the authors examine the relationships between rebels, the government, and civilians. This approach serves as a springboard for exploring other aspects of modern conflict, including the suppression of rebel activity, the role of mobile communications networks, the links between aid and violence, and why conventional military methods might provide short-term success but undermine lasting peace. Ultimately the authors show how the stronger side can almost always win the villages, but why that does not guarantee winning the war. Small Wars, Big Data provides groundbreaking perspectives for how small wars can be better strategized and favorably won to the benefit of the local population.
