Yet many organizations face difficulties implementing a vision of delivering experiences beyond the provision of goods and services while students and aspiring professionals struggle to piece together the principles of experience design from disparate, often disconnected disciplines and approaches.In this book, J. Robert Rossman and Mathew D. Duerden present a comprehensive and accessible introduction to experience design. They synthesize the fundamental theories and methods from multiple disciplines and lay out a process for designing experiences from start to finish. Rossman and Duerden challenge us to reflect on what makes a great experience from the user's perspective, drawing attention to both the macro and micro levels. They present interdisciplinary research underlying key concepts such as memory, intentionality, and dramatic structure in a down-to-earth style. Designing Experiences features detailed instructions and numerous real-world examples that clarify theoretical principles, making it useful for students and professionals. An invaluable overview of a growing field, the book provides readers with the tools they need to design innovative and indelible experiences.",

Count Lev Nikolayevich Tolstoy (1828–1910), also known in English as Leo Tolstoy, was a Russian writer. Generally considered to be one among the greatest novel writers of all time, he was nominated for the Nobel Prize in literature each year between 1902 and 1906; as well as the Nobel Peace Prize in 1901, 1902, and 1910. Other notable works by this author include: \"Anna Karenina\" (1877), \"The Cossacks\" (1863), and \"Resurrection\" (1899). Read & Co.

Am Chor entzündet sich die Frage, wie die Gemeinschaft auftritt.Maria Kuberg untersucht in detaillierten Lektüren chorischer Theaterstücke von Heiner Müller, Botho Strauß, Elfriede Jelinek, Tankred Dorst, Ewald Palmetshofer, Rainald Goetz, Gert Jonke und René Pollesch, wie der Chor in zeitgenössischen deutschsprachigen Theatertexten zur Sprache kommt. Welche Formen nimmt die Chor-Gemeinschaft dabei im Text an? Und wie korrespondieren diese mit der dramatischen Gattung, die doch grundsätzlich die Handlungen Einzelner vorführt? Das sind die leitenden Fragen dieser erhellenden Erkundung des Theaters der Gegenwart, die es als Reflexion über Gemeinschaft profiliert.Dabei operiert die Untersuchung auf drei historischen Ebenen: Chorische Theatertexte aus dem späten 20. und frühen 21. Jahrhundert werden mit einer theatralen Tradition konfrontiert, die bis in die griechische Antike zurückreicht. Zwischen den antiken und den aktuellen Texten vermittelt die philosophisch-ästhetische Auseinandersetzung mit dem Chor, wie sie im 19. Jahrhundert Schiller, A. W. und F. Schlegel, Hegel und Nietzsche führen. Im Zusammenspiel dieser drei Ebenen wird so eine Theorie des Chorischen entwickelt, die Gattungsaspekte und Gemeinschaftstheorien gleichermaßen berücksichtigt und die das ästhetische wie auch das politische Potenzial der untersuchten Texte erschließt.",

The Project involves scholars from the Pakistan Heritage Society, the British Museum, the Institute of Archaeology (UCL), Bryn Mawr College and the University of Cambridge. This is the first in a series of volumes that present the final reports of the exploration and excavations carried out by the Bannu Archaeological Project. It marks the first attempt to contextualise the earliest village settlements in northwest Pakistan, along with those situated in other parts of the borderlands zone at the western margins of South Asia. An extensive range of archaeological data from the Bannu Archaeological Project excavations at Sheri Khan Tarakai, including stratigraphic, architectural, ceramic, lithic, small find and bioarchaeological elements, are presented, along with the results of surveys and excavations at several other sites in the Bannu Basin and the adjacent Gomal Plain. The work establishes the nature of the relationships between these sites and other early villages elsewhere in South, central and greater West Asia.",
