There has been much concern over the impact of partisan echo chambers and filter bubbles on public debate. Is this concern justified, or is it distracting us from more serious issues? Axel Bruns argues that the influence of echo chambers and filter bubbles has been severely overstated, and results from a broader moral panic about the role of online and social media in society. Our focus on these concepts, and the widespread tendency to blame platforms and their algorithms for political disruptions, obscure far more serious issues pertaining to the rise of populism and hyperpolarisation in democracies. Evaluating the evidence for and against echo chambers and filter bubbles, Bruns offers a persuasive argument for why we should shift our focus to more important problems. This timely book is essential reading for students and scholars, as well as anyone concerned about challenges to public debate and the democratic process.

To achieve an effective in vivo diagnosis of prosencephalic malforma- tions it is necessary to have a systematic method that is closely corre- lated to the gross morphology of the inner and outer surfaces of the brains involved, since those are the features that are demonstrable by pneumography, angiography and computer tomography. An attempt was made to use the existing classification systems, but it then became obvious that they are poorly adapted to the requirements of modem neuroradiology. The many different forms of prosencephaly therefore needed to be re-categorized on the basis of a series of typical speci- mens. The new system is not only simpler and thus more clear-cut from the standpoint of the (in vivo) diagnosis, but in the present author's opinion it also has some advantages as regards the theoretical aspects of the problem. An essential prerequisite for its clarity is that the mal- formations belonging to theyrosepsephalysQe

Quantum computation and information is one of the most exciting developments in science and technology of the last twenty years. To achieve large scale quantum computers and communication networks it is essential not only to overcome noise in stored quantum information, but also in general faulty quantum operations. Scalable quantum computers require a far-reaching theory of fault-tolerant quantum computation. This comprehensive text, written by leading experts in the field, focuses on quantum error correction and thoroughly covers the theory as well as experimental and practical issues. The book is not limited to a single approach, but reviews many different methods to control quantum errors, including topological codes, dynamical decoupling and decoherence-free subspaces. Basic subjects as well as advanced theory and a survey of topics from cutting-edge research make this book invaluable both as a pedagogical introduction at the graduate level and as a reference for experts in quantum information science.

Dieser Band behandelt das weite Gebiet der organisch bedingten psychischen Stoerungen. Einleitend werden die Grundlagen der psychoorganischen Syndromlehre, der Neuropsychologie, Neurophysiologie und Neuroradiologie abgehandelt. Der Hauptteil des Bandes beschreibt in mehreren Beitragen alle wichtigen Gruppen psychiatrischer Krankheiten, die organisch bedingt sind. Ein Bericht uber den gegenwartigen Stand der Schlafforschung beschliesst den Band. Insgesamt wird mit diesem Band ein zusammenfassender UEberblick uber ein Thema vermittelt, das trotz seiner grossen epidemiologischen Bedeutung seit langerer Zeit nicht mehr im Vordergrund des psychiatrischen Interesses gestanden hat.
