This Festschrift volume, published in honour of Peter Buneman, contains contributions written by some of his colleagues, former students, and friends. In celebration of his distinguished career a colloquium was held in Edinburgh, Scotland, 27-29 October, 2013. The articles presented herein belong to some of the many areas of Peter's research interests.

Computation, itself a form of calculation, incorporates steps that include arithmetical and non-arithmetical (logical) steps following a specific set of rules (an algorithm). This uniquely accessible textbook introduces students using a very distinctive approach, quite rapidly leading them into essential topics with sufficient depth, yet in a highly intuitive manner. From core elements like sets, types, Venn diagrams and logic, to patterns of reasoning, calculus, recursion and expression trees, the book spans the breadth of key concepts and methods that will enable students to readily progress with their studies in Computer Science.

Paying tribute to one of the more original theorist of the late 20th and early 21st century, Rational Radicalism and Political Theory probes the thought of Stephen Eric Bronner. This collection of essays encompasses themes such as the Enlightenment's radical legacy, the impulse of cosmopolitanism, the rejuvenation of socialist theory and politics, and advances in Critical Theory. These essays make new contributions to many areas of left political theory, while at the same time reflecting on the ways Stephen Bronner's ideas serve to generate a new kind of critical political theory. Blending political and intellectual history, normative and moral argumentation, and forays into the nature of politics itself, this book brings together new voices in political theory to assess Bronner's contributions and pave new paths for the future of political theory.

The resurgence of nationalism accompanying the decline of Communism has been taken to indicate the failure of socialist theory to grasp the nature of this phenomenon. Against both those who argue that the radical tradition has ignored and underestimated nationalism and those who accuse it of economic reductionism, this careful analysis of the idea of the nation as it was developed in the work of the major thinkers of the international labor movement reveals evidence of how seriously they grappled with nationalism.

Each of the main sections of the book focuses on the most influential theorists of the international labor movement as it became organized and grew: Bakunin, Marx, and Engels and the concern of the First International (1864-1876) with class solidarity across political borders; Lenin, Luxemburg, and Bauer and the preoccupation of the Second International (1889-1914) with socialism in ethnically plural societies; Stalin and Gramsci in relation to the substitution by the Third International (1919-1943) of nation-building and national liberation for the old class project.

In the conclusion, the author examines the relationships among ethnic and civic nationality, national self-determination, republican institutions, and the process of globalization from the perspective of the post-Soviet era and in the light of social theory and Kant's ideas about cosmopolitan right.
