Although more than 40 years have gone by since Jürgen Habermas originally narrated the birth and the decline of the bourgeois public sphere (Habermas, 1989(Habermas, /1962, this ideal still holds a strong grip on our attempts to either critically examine or re-invent the idea of modern democracy. Since the mid-1990s the work of Jürgen Habermas has become once again relevant, this time regarding the political impact of new information and communication technologies, and in particular the internet. Acknowledging the legitimation and steering crisis of the modern democratic state and the corrosion of the critical role of the current mass media system, many scholars turned to the new medium attempting to re-invent, on a normative as well as on an empirical basis, a politically functioning public sphere (

Plants, animals and some fungi undergo processes of cell specialization such that specific groups of cells are adapted to carry out particular functions. One of the more remarkable examples of cellular development in higher plants is the formation of water-conducting cells that are capable of supporting a column of water from the roots to tens of metres in the air for some trees. The Zinnia mesophyll cell system is a remarkable tool with which to study this entire developmental pathway in vitro. We have recently applied an RNA fingerprinting technology, to allow the detection of DNA fragments derived from RNA using cDNA synthesis and subsequent PCR-amplified fragment length polymorphisms (cDNA-AFLP), to systematically characterize hundreds of the genes involved in the process of tracheary element formation. Building hoops of secondary wall material is the key structural event in forming functional tracheary elements and we have identified over 50 partial sequences related to cell walls out of 600 differentially expressed cDNA fragments. The Zinnia system is an engine of gene discovery which is allowing us to identify and characterize candidate genes involved in cell wall biosynthesis and assembly.

Internet use among young people in multicultural societies is differentiated according to socioeconomic and cultural factors, one of which is their ethnic background. This study is concerned with the unreported case of Cyprus – the last divided country in Europe, with most Greek Cypriots living in the south and most Turkish Cypriots living in the northern part of the island. The study explores two main questions: First, are online experiences of young people in Cyprus shaped by socioeconomic factors, such as gender, education, and income? Second, is ethnicity a defining factor regarding the kinds of activities young people undertake online? Analysis of data obtained by a representative sample survey of about 350 young adult Cypriots aged 18–24 in both communities suggests the existence of a ‘reverse digital divide’, as the more disadvantaged community engages more often in expression, association, and learning online. This finding provides support for the diversification hypothesis that suggests a compensatory or remedial use of the Internet by disadvantaged youths.

This study draws on several data activism projects and applies discursive interface analysis to understand the material means by which activist software strives to empower users vis-à-vis data power. The analysis uncovers four types of oppositional affordances: (i) enabling the use of hidden affordances (ii) imagining new affordances (iii) creating meta-affordances (resignifying perceptible affordances of corporate platforms and reconstructing their meaning), and (iv) creating anti-affordances (hindering or distorting corporate platforms’ affordances to the extent that they do not perform their intended function). Although not without limitations, oppositional affordances reveal the actual agentic possibilities of data activism for users other than activists to affect the very algorithms that produce them as datafied subjects. The proposed typology provides a means for further empirical analysis of critical software and its subversive potential for users. The article concludes with a critical discussion of data activism as a means of vernacular critical praxis.

This entry analyzes the meaning and impact of interactive journalism on journalistic content, as well as the main research perspectives and relevant findings. The concept of interactive journalism highlights the potential for the democratization of journalism by allowing the audience to play an active role in the process of newsmaking within the realm of professional journalism. Findings suggest both positive and negative implications of interactive journalism. The majority of users are not interested in producing content; and mainstream media attempt to control participation while adopting a market‐driven rather than a civic‐oriented approach to user‐generated content (UGC). Yet, recent evidence suggests that digital start‐ups, hyperlocal news media, and specific social groups are collaborating in the direction of a more pluralistic news agenda aiming to elevate public debate and deal with society's problems.

This study describes the design of a serious game for social change (“Fact Finders”) that presents intergroup conflicts through historical inquiry and multiperspectivity. A pre-test post-test experimental design examined the game’s effect on undergraduates’ perceptions of conflicts in history. Participants included 97 Greek Cypriots (direct parties of the conflict) and 79 Slovenians (third parties of the conflict) who interacted with and evaluated the game online. Data sources included a 17-item questionnaire on perceptions of conflicts in history and gameplay learning analytics data. Findings indicated that both groups’ perceptions for historical source evaluation and understanding multiperspectivity changed significantly after the game. The game significantly changed perceptions about the constructedness of history and the ability to overcome their country’s troubled past only for direct parties of the conflict. The study provides empirical evidence demonstrating the potential value of serious games for affecting young people’s perceptions of intractable intergroup conflicts and their desire to overcome troubled pasts.
