Trick 17: Mediengeschichten zwischen Zauberkunst und Wissenschaft
Full text link"Der Zauber der Medien speist sich aus ihrem Geheimnis: Den Usern von heute sind Laptop, Smartphone oder Tablet eine Blackbox, die ihre Sinne im Bann hält und die Techniktricks im Inneren hinter einer opaken Oberfläche verbirgt. Doch solche Verzauberung ist nicht neu. Um ihr auf die Spur zu kommen, nähert sich dieses Buch der Mediengeschichte der Zauberei an der Schwelle zwischen magischem Moment und Ent-Täuschung. Nicht selten folgt einer geradezu übernatürlich wirkenden Zaubervorführung die wissenschaftliche Erklärung und Offenlegung ihrer Tricks. Ein solcher Akt der Entzauberung mag zwar magische Momente als faulen Zauber demaskieren. Er rückt dafür jedoch die Technologien der Täuschung ins Rampenlicht: Erst die Ausnutzung physikalischer Gesetze, das Konstruieren mechanischer Zauberapparate und das Spiel mit der Wahrnehmung der Zuschauer machen deren 'Verzauberung' möglich. Sie erlaubt, die Frage nach Wissen, dem medialen Zugriff auf unsere Sinne und dem sinnlichen Zugriff auf unsere Welt erneut zu stellen." (Autorenreferat

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Zootechnologies
Full text linkSwarming has become a fundamental cultural technique related to dynamic processes and an effective metaphor for the collaborative efforts of society. This book examines the media history of swarm research and its significance to current socio-technological processes. It shows that the hype about collective intelligence is based on a reciprocal computerization of biology and biologization of computer science: After decades of painstaking biological observations in the ocean, experiments in aquariums, and mathematical model-making, it was swarms-inspired computer simulation which provided biological researchers with enduring knowledge about animal collectives. At the same time, a turn to biological principles of self-organization made it possible to adapt to unclearly delineated sets of problems and clarify the operation of opaque systems - from logistics to architecture, or from crowd control to robot collectives. As zootechnologies, swarms offer performative, synthetic, and approximate solutions in cases where analytical approaches are doomed to fail
