Evolutionary Games in Complex Topologies

Evolutionary Games in Complex Topologies

There are many examples of cooperation in Nature: cells cooperate to form tissues, organs cooperate to form living organisms, and individuals cooperate to raise their offspring or to hunt. However, why cooperation emerges and survives in hostile environments, when defecting would be a much more profitable short-term strategy, is a question that still remains open. During the past few years, several explanations have been proposed, including kin and group selection, punishment and reputation mechanisms, or network reciprocity. This last one will be the center of the present study. The thesis explores the interface between the underlying structure of a given population and the outcome of the cooperative dynamics taking place on top of it, (namely, the Prisoner’s Dilemma Game). The first part of this work analyzes the case of a static system, where the pattern of connections is fixed, so it does not evolve over time. The second part develops two models for growing topologies, where the growth and the dynamics are entangled.

Psychological Components of Sustainable Peace

Psychological Components of Sustainable Peace

Scholarship on the psychology of peace has been accumulating for decades. The approach employed has been predominantly centered on addressing and preventing conflict and violence and less on the conditions associated with promoting peace. Concerns around nuclear annihilation, enemy images, discrimination, denial of basic human needs, terrorism and torture have been the focal points of most research. The Psychological Components of a Sustainable Peace moves beyond a prevention-orientation to the study of the conditions for increasing the probabilities for sustainable, cooperative peace. Such a view combines preventative scholarship with a promotive-orientation to the study of peaceful situations and societies. The contributors to this volume examine the components of various psychological theories that contribute to the promotion of a harmonious, sustainable peace. Underlying this orientation is the belief that promoting the ideas and actions which can lead to a sustainable, harmonious peace will not only contribute to the prevention of war, but will also lead to more positive, constructive relations among people and nations and to a more sustainable planet. The Psychological Components of a Sustainable Peace is valuable and stimulating reading for researchers in peace psychology, political psychology, and conflict resolution as well as others who are interested in developing a sustainable, harmonious world.

Japan and the League of Nations

Japan and the League of Nations

Japan joined the League of Nations in 1920 as a charter member and one of four permanent members of the League Council. Until conflict arose between Japan and the organization over the 1931 Manchurian Incident, the League was a centerpiece of Japan’s policy to maintain accommodation with the Western powers. The picture of Japan as a positive contributor to international comity, however, is not the conventional view of the country in the early and mid-twentieth century. Rather, this period is usually depicted in Japan and abroad as a history of incremental imperialism and intensifying militarism, culminating in war in China and the Pacific. Even the empire’s interface with the League of Nations is typically addressed only at nodes of confrontation: the 1919 debates over racial equality as the Covenant was drafted and the 1931-1933 League challenge to Japan’s seizure of northeast China. This volume fills in the space before, between, and after these nodes and gives the League relationship the legitimate place it deserves in Japanese international history of the 1920s and 1930s. It also argues that the Japanese cooperative international stance in the decades since the Pacific War bears noteworthy continuity with the mainstream international accommodatationism of the League years. Thomas Burkman sheds new light on the meaning and content of internationalism in an era typically seen as a showcase for diplomatic autonomy and isolation. Well into the 1930s, the vestiges of international accommodationism among diplomats and intellectuals are clearly evident. The League project ushered those it affected into world citizenship and inspired them to build bridges across boundaries and cultures.Burkman’s cogent analysis of Japan’s international role is enhanced and enlivened by his descriptions of the personalities and initiatives of Makino Nobuaki, Ishii Kikujir , Nitobe Inaz , Matsuoka Y suke, and others in their Geneva roles.
