Sommario/riassunto

The latest edition of this classic is updated with new problem sets and materialThe Second Edition of this fundamental textbook maintains the book's tradition of clear, thought-provoking instruction. Readers are provided once again with an instructive mix of mathematics, physics, statistics, and information theory.All the essential topics in information theory are covered in detail, including entropy, data compression, channel capacity, rate distortion, network information theory, and hypothesis testing. The authors provide readers with a solid understanding of the underlying t

Sommario/riassunto

This book addresses two developments in the conceptualisation of citizenship that arise from the »war on terror«, namely the re-culturalisation of membership in a polity and the re-moralisation of access to rights. Taking an anthropological perspective, it traces the



ways in which the trans-nationalisation of the »war on terror« has affected notions of »the dangerous other« in different political and social contexts, asking what changes in the ideas of the state and of the nation have been promoted by the emerging culture of security, and how these changes affect practices of citizenship and societal group relations.

»Hier liegt die große Stärke des Bandes: Mit rechtssoziologischen, ethnographischen und diskursanalytischen Perspektiven auf die Details breit gefächerter Fallbeispiele werden die vielen Facetten und die uneinheitlichen Effekte des ›War on Terror‹ deutlich.«

»Die Konkretheit des Ausgangsproblems und die Anschaulichkeit der vielen Fallstudien machen die Lektüre zum Genuss. Das Buch bereichert zunächst die Stafrechtssoziologie und darüber hinaus die Staatswissenschaft.«

»Die Stärke des Sammelbandes liegt [...] in der Betrachtung des sozialen Gefüges in den heterogenen Beispielfällen.«
