"Es ist echt schwer, das richtig zu machen": Eine FLIMMO-Elternbefragung zum Medienstart
No full textMedienerziehung beginnt nicht erst mit dem Smartphone, sondern bereits im frühen Kindesalter – und stellt viele Eltern vor Unsicherheiten. Der Beitrag beleuchtet auf Basis qualitativer Interviews mit Eltern von Kindern unter sechs Jahren zentrale Haltungen, Herausforderungen und Bedürfnisse. Deutlich wird: Eltern wünschen sich konkrete, alltagsnahe Unterstützung, um Mediennutzung altersgerecht, bedürfnisorientiert und reflektiert zu begleiten
BR backstage: Ein Jugendmedientag zur Förderung von Medienkompetenz
No full textIm Juni 2015 veranstaltete der Bayerische Rundfunk zum ersten Mal einen Jugendmedientag, um Jugendlichen Medien begreifbar zu machen: BR backstage. Rund 1.500 bayerische Schülerinnen und Schüler aller Schularten ab der siebten Jahrgangsstufe und ihre Lehrkräfte folgten der Einladung, einen Blick hinter die Kulissen der öffentlich-rechtlichen Sendeanstalt zu werfen. Das Institut für Kommunikationswissenschaft und Medienforschung der LMU München hat diesen Tag wissenschaftlich begleitet und evaluiert

No full textRegulating new Bottlenecks of Digital Television Distribution. An Analysis of the Policy Making Process in Switzerland
Full text linkThe contributions to this book approach communication and media policy in the era of the Internet from two perspectives: Theories and processes. Special attention is given, on the one hand, to the question of how communication policy-making is transformed due to technical evolution which is intertwined with social and economic developments. On the other hand, this book considers how these transformations can be studied and what insights are produced by distinct theoretical approaches
Digitale und mobile Medien in Familien mit kleinen Kindern: Ergebnisse der Langzeitstudie FamilienMedienMonitoring
No full textDie Ergebnisse der Langzeitstudie FaMeMo zeigen, dass bereits die jüngsten Kinder mit digitalen und mobilen Medien intensiv in Kontakt sind. Es wird der Bedarf nach einer flexiblen, kindgerechten Medienerziehung deutlich, die an die jeweiligen familiären Bedingungen angepasst ist. So können Familien und besonders die Kinder profitieren und den Herausforderungen einer Lebenswelt gerecht werden, in der Medien allgegenwärtig sind
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
