THE EVOLUTION OF THE SOFA-TV IN THE NEW DIGITAL SCENARIO
No full textThe traditional television is now at a turning point because the introduction of digital
technology has changed the competitive context: it has modified the bargain power of the
traditional players by offering new opportunities to the new entrants and imposing new
strategies to the existing ones. This paper, basing on 32 case studies and the census of Sat TV,
DTT and IPTV offerings, aims at describing the current state of channel offerings,
individualizing the principal players and identifying their strategies, thus allowing us to give a
few predictions as to the possible future changes in the industry. The analysis will have a
general applicability, as the considerations made are not particularly country-specific, although
performed within the Italian context, one of the most advanced in the development of digital TV
platforms
Sofa-TV: The New Digital Landscape
Get PDFTelevision is attracting an enormous amount of attention from both researchers and managers, due to the profound changes that are taking place thanks to the diffusion of digital technology. The study of the digital landscape of television, including the players competing in its arena and their strategies, is well worth the effort. This paper, based on 32 case studies and the census of the Sofa-TV (Sat TV, DTT, and IPTV) offerings, aims at describing the current state of channel offerings, individualizing the principal players, and identifying their strategies, thus allowing us to give a few predictions as to the possible future changes in the industry. The analysis will have a general applicability, as the considerations made are not particularly country-specific, although performed within the Italian context, one of the most advanced in the development of digital television platforms
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
The new way to think television on the Web
No full textTelevision is attracting an enormous amount of attention from both
researchers and managers, due to profound changes that are taking place thanks
to the diffusion of digital technology. The Internet and the Web, affecting the
overall landscape, the consumer habits, the strategies of the players, are playing
a key role in the TV revolution. This paper, based on 26 case studies, a survey
involving over 200 players and a complete census of all the channels provided
via Web in Italy, aims at defining the current state of the Web TV (we call it
Desktop-TV) in Italy and identifying the main business models and the
strategies adopted by the players, thus allowing us to give a few predictions on
the possible future changes in the industry. Although the analyses have been
carried out in Italy, the results will have a general applicability, since the Web
is not country specific by definition and the majority of players included in this
research have international relevance
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
