Structural layers of communication on Twitter
No full textTwitter is used for a range of communicative purposes. These extend from personal tweets that address what used to be Twitter’s default question, “What’s happening?”, through one-on-one @reply conversations between close friends and attempts at getting the attention of celebrities and other public actors, to discussions in communities built around specific issues—and back again to broadcast-style statements from well-known individuals and brands to their potentially very large retinue of followers

The Digital Public Sphere : Challenges for Media Policy
No full textUntil recently, media policy was thought of as national, media-specific, and as part of the cultural domain. All is changing in a digital public sphere: first, by the processes of globalization in a broad sense; second, by a blurring of borders between media, which can be summed up as convergence; and third, by a more far-reaching commercialisation of the media. The transformation triggered by these developments are ongoing and have been so for quite a few years. Thus, it is time to take stock. The different contributions in this book set out to do that.With basis in the idea that media policy is fundamentally about regulating the public sphere in accordance with central democratic ideals, the book covers a wide range of issues: Transnational online television distribution; the trouble with building and opening digital audiovisual archives; the impact of recent EU regulations on global conglomerates as well as national public service broadcasters; the debate on net neutrality; the idea of the participating public in policy-making; the regulation of freedom of speech on the internet; as well as the impact of legal globalization on media policy itself

Public Value, the BBC and Humpty Dumpty Words – does Public Value Management Mean What it Says?
No full textAbout the book:
Public service broadcasters across Europe are venturing into the digital world, launching niche TV channels, building extensive websites, developing commercial services, entering into partnerships with external actors, and exploring new ways to reach users, whether its through smart phone apps or screens in public spaces. Such endeavours intensify fundamental discussions about what we need public service media institutions for. These are complex discussions, building on history, encompassing new technology, and involving a range of strong stakeholders. Recently, the so-called public value test has emerged as the focal point for these discussions. As a detailed regulatory scheme to measure the public worth and possible market impact of planned publicly funded media services, the public value test is causing controversy across Europe. This collection of short essays from academics, regulators, public broadcasters and private media representatives, provides thought-provoking perspectives on the state of play of public value tests in a range of European states. In so doing, the book is a topical intervention in the ongoing debate about the future of our media systems

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
The Italian Way to Teletext. The History, Structure and Role of Televideo Rai
No full textSince 1984, Televideo has been a constant presence (even if sometimes unnoticed and neglected) in Italian television and a service provided by the national Public Service Broadcaster Rai. After years of technical and editorial experimentation, in Italy the role of teletext became important especially during the 1980s and the 1990s: it offered a series of textual information and data to a large number of television viewers, generating common practices and shared references, and influencing news production processes as well as the consumer electronics industry. In recent years, with the diffusion of PCs, the world wide web, and digital media Televideo central role has been decreased, yet it still offers its service to mature audiences and experiments some connections with digital outlets. Building on both primary and secondary sources (Rai archives, surveys, production data, printed press, promotional materials, etc.), the essay aims to trace the history of Italian teletext, through a multiple set of lenses: technology, politics, economy/business, content production, and audience. As a result, the fundamental role of public service TV in developing the “Italian way to teletext” will be described, taking into account national and regional pages (together with their less successful commercial counterparts). Televideo emerges then as a part of a complex intermedial landscape, supplementing newspapers and TV news as well as anticipating and then connecting television and digital environment
