Activismo ciudadano y acontecimientos políticos en la transformación de la esfera pública digital en españa: del sms ¡pásalo! a Podemos

This paper discusses digital communication, activism and political system in Spain from a critical-historical perspective. The results of combined empirical and analytical research indicate that a critical digital public sphere emerged in 2004 affecting the evolution of the political sphere to this day. Traditional parties had a slow and instrumental approach to the digital realm. Conversely, cyber-activism unfolded new options of political action, both in the short and long term, transforming the bipartisan system.El artículo aborda la comunicación digital, el activismo y el sistema político en España desde una perspectiva crítica-histórica.

Blogging on the ice: Connecting audiences with climate-change sciences

Scientists working in Antarctica have recognized the need to counteract problems associated with mainstream media's treatment of the climate-change crisis. For this reason, several of them have assumed the role of citizen journalists in order to report on the effects of global warming first-hand. More specifically, they have chosen to communicate directly with the general public through official or personal blogs. In so doing they are capitalizing on the way the Internet is changing science news and journalism. This article draws on an analysis of more than 50 Antarctic blogs published during the International Polar Year (2007-08), as well as data from e-interviews with a broad selection of bloggers, in order to examine how scientists 'on the ice' act as citizen journalists. The article explores the idea of citizen journalism as education and the extent to which the scientists achieve an unmediated form of communication through their blogging efforts. It concludes by suggesting this new form of citizen journalism, beyond raising people's awareness of the climate-change crisis, also signals an important way in which mainstream environmental reporting can be reinvigorated. © 2013 Intellect Ltd Article

An analysis of interactions within and between extreme right communities in social media

Many extreme right groups have had an online presence for some time through the use of dedicated websites. This has been accompanied by increased activity in social media websites in recent years, which may enable the dissemination of extreme right content to a wider audience. In this paper, we present exploratory analysis of the activity of a selection of such groups on Twitter, using network representations based on reciprocal follower and mentions interactions. We find that stable communities of related users are present within individual country networks, where these communities are usually associated with variants of extreme right ideology. Furthermore, we also identify the presence of international relationships between certain groups across geopolitical boundaries

Participation, Remediation, Bricolage: Considering Principal Components of a Digital Culture

Within media theory the worldwide shift from a 19th century print culture via a 20th century electronic culture to a 21st century digital culture is well documented. In this essay the emergence of a digital culture as amplified and accelerated by the popularity of networked computers, multiple-user software and Internet is investigated in terms of its principal components. A digital culture as an undetermined praxis is conceptualized as consisting of participation, remediation and bricolage. Using the literature on presumably ‘typical’ Internet phenomena such as the worldwide proliferation of Independent Media Centres (Indymedia) linked with (radical) online journalism practices and the popularity of (individual and group) weblogging, the various meanings and implications of this particular understanding of digital culture are explored. In the context of this essay digital culture can be seen as an emerging set of values, practices and expectations regarding the way people (should) act and interact within the contemporary network society. This digital culture has emergent properties with roots both in online and offline phenomena, with links to trends and developments pre-dating the World Wide Web, yet having an immediate impact and particularly changing the ways in which we use and give meaning to living in an increasingly interconnected, always on(line) environment

Structure and Dynamics of Information Pathways in Online Media

Diffusion of information, spread of rumors and infectious diseases are all instances of stochastic processes that occur over the edges of an underlying network. Many times networks over which contagions spread are unobserved, and such networks are often dynamic and change over time. In this paper, we investigate the problem of inferring dynamic networks based on information diffusion data. We assume there is an unobserved dynamic network that changes over time, while we observe the results of a dynamic process spreading over the edges of the network. The task then is to infer the edges and the dynamics of the underlying network. We develop an on-line algorithm that relies on stochastic convex optimization to efficiently solve the dynamic network inference problem. We apply our algorithm to information diffusion among 3.3 million mainstream media and blog sites and experiment with more than 179 million different pieces of information spreading over the network in a one year period. We study the evolution of information pathways in the online media space and find interesting insights. Information pathways for general recurrent topics are more stable across time than for on-going news events. Clusters of news media sites and blogs often emerge and vanish in matter of days for on-going news events. Major social movements and events involving civil population, such as the Libyan's civil war or Syria's uprise, lead to an increased amount of information pathways among blogs as well as in the overall increase in the network centrality of blogs and social media sites.Comment: To Appear at the 6th International Conference on Web Search and Data Mining (WSDM '13

Real-Time Classification of Twitter Trends

Social media users give rise to social trends as they share about common interests, which can be triggered by different reasons. In this work, we explore the types of triggers that spark trends on Twitter, introducing a typology with following four types: 'news', 'ongoing events', 'memes', and 'commemoratives'. While previous research has analyzed trending topics in a long term, we look at the earliest tweets that produce a trend, with the aim of categorizing trends early on. This would allow to provide a filtered subset of trends to end users. We analyze and experiment with a set of straightforward language-independent features based on the social spread of trends to categorize them into the introduced typology. Our method provides an efficient way to accurately categorize trending topics without need of external data, enabling news organizations to discover breaking news in real-time, or to quickly identify viral memes that might enrich marketing decisions, among others. The analysis of social features also reveals patterns associated with each type of trend, such as tweets about ongoing events being shorter as many were likely sent from mobile devices, or memes having more retweets originating from a few trend-setters.Comment: Pre-print of article accepted for publication in Journal of the American Society for Information Science and Technology copyright @ 2013 (American Society for Information Science and Technology

A History of Journalism on the Internet: a state of the art and some methodological trends

La historiografía de los nuevos medios ha ido adquiriendo, sobre todo en la última década, una considerable importancia, especialmente aquella dedicada a la investigación histórica sobre la World Wide Web (vide Brügger, 2010). Peviamente, la hisotria de los medios de comunicación se había beneficiado de la perspectiva de la historia social y cultural, representada, entre otros, por Burke o Briggs. Desde esos puntos de vista, intentamos en este artículo explicar la historia de las primeras décadas de periodismo en internet, y poner de manifiesto algunos retos metodológicos relacionados con la investigación histórica sobre el tema.Historiography of new media has gained a remarkable importance in the last decade, especially that devoted to the historical research about the World Wide Web (i.e., Brügger, 2010). Previously, the history of the media was enforced by the perspective of the social and cultural history currents (Burke; Briggs). From these points of views, we attempt in this paper to trace the history of the first decades of online journalism, and to highlight some methodological challenges related to historical research applied to it

How open are journalists on Twitter? Trends towards the end-user journalism

The many activities of journalists on Twitter should be analyzed. Are they doing a different kind of journalism? With a content analysis of 1125 tweets, this study reveals trends of some Spanish journalists using Twitter. A traditional role like gatekeeping can be highly amplified in terms of transparency and accountability with actions as retweeting or linking. The landscape offered by this platform is framed with the "ambient journalism", which will help to understand the proposal of this study: the end-user journalism. The findings will show the level of opening with the audience in aspects about replies, requests and linking
