Sommario/riassunto |
|
Die Prozesse kultureller Transformation in den gegenwärtigen Demokratien lassen sich mit den traditionellen Ansätzen der politischen Kulturforschung, bei denen vor allem politische Präferenzen untersucht werden, nicht mehr adäquat erfassen. Um die Wirksamkeit kultureller Dispositionen der Wahrnehmung und Beurteilung des Politischen sowie politischen Entscheidens und Handelns heute verstehen und analysieren zu können, bedarf es neuer Konzepte. Dieser Band versammelt Beiträge mit Befunden aktueller Forschung zu den politischen Dimensionen von Kultur und den kulturellen Dimensionen von Politik sowie mit innovativen theoretischen, programmatischen und methodischen Ansätzen. |
»Die Lektüre des Bandes [nutzt] nicht nur theoretisch interessierten Lesern, sondern auch denjenigen, die Impulse für die Unterrichtspraxis suchen.« |
