We analyze the market for online and offline media in a model of two-dimensional spatial competition where media outlets sell content and advertising space. Consumer preferences are distributed along the style and type of news coverage where the distance costs may vary across dimensions. For integrated provision of online and offline platforms we show that entering the online market reduces average profits and may even constitute a prisoner's dilemma. Specialized provision may yield polarization in the style and type dimensions. This is in contrast to the maximum–minimum differentiation result previously established in the literature on multidimensional horizontal competition. We show that maximal differentiation in both dimensions occurs due to the discrete nature of the type dimension and asymmetric advertising markets.

La plupart des études sur l'étiquetage social porte sur une plateforme ou un type de plateforme précis, ce qui limite la portée de leurs résultats. Cette étude explore et compare les pratiques d'étiquetage social de quatre plateformes--Goodreads, un catalogue de bibliothèque publique, Last.fm et WordPress--au moyen d'une étude de cas multiples et emboîtés. Le contenu généré par les utilisateurs, principalement les étiquettes ou "tags", lié au livre Casino royale de Ian Fleming ou à ses produits dérivés ou associés (p. ex. : chanson thème, film, billet de blogue) a été analysé avec une approche qualitative et inductive. L'analyse révèle que le contenu généré par les utilisateurs des quatre plateformes mettait l'emphase sur les événements historiques associés au livre tout en fournissant de nombreux points d'accès plus subjectifs : recommandation, ton, ambiance, opinion, expérience de lecture, d'écoute ou de visionnement. On remarque par ailleurs des différences entre les étiquettes associées au livre et à ses produits dérivés : alors que le contenu généré par les utilisateurs en lien avec le produit d'origine dans les catalogues de bibliothèques et dans Goodreads portait essentiellement sur le livre, les étiquettes attribuées par les utilisateurs aux produits dérivés dans Last.fm (la chanson thème du film) et WordPress (des billets de blogues sur le livre ou le film) renvoyaient souvent à d'autres produits culturels, incluant des livres, de la musique et des films.

Crowdinvesting consiste na captação de recursos financeiros por empreendedores, por meio de uma plataforma online na internet, em que os investidores recebem em troca de seus aportes financeiros uma participação na empresa nascente investida. Trata-se de uma modalidade de financiamento peculiar, uma vez que usualmente realiza a oferta pública de valores mobiliários. O objetivo deste trabalho é identificar elementos para se pensar na qualificação jurídica da plataforma online de crowdinvesting, a partir da descrição de suas atividades realizadas no âmbito da oferta pública de valores mobiliários. Para tanto, foi escolhida a plataforma online da Broota Brasil como objeto único de análise, pois é a empresa pioneira na atividade. Identificar os elementos que propiciam uma reflexão acerca da qualificação jurídica que a plataforma online de crowdinvesting é importante, pois permite a (i) reflexão acerca do seu possível tratamento jurídico; e (ii) verificar se há segurança jurídica nas atividades cursadas no âmbito da plataforma online. Para nortear o presente trabalho, foram eleitas duas hipóteses de pesquisa, considerando que a plataforma online consiste em um ambiente virtual que disponibiliza espaço para a realização de ofertas públicas de valores mobiliários, sendo reputada como (i) mercado de balcão organizado; ou (ii) mercado de balcão não organizado. Assim, é realizada a descrição das atividades da plataforma online da Broota Brasil no âmbito da realização de oferta pública de valores mobiliários. Após, com base na legislação e doutrina específica, foi efetuada a descrição das características que conceituam juridicamente as referidas hipóteses. Em seguida, foram identificadas se tais características estavam presentes nas atividades desenvolvidas pela plataforma online da Broota Brasil. Por fim, não sendo reveladas tais características, sugere-se uma agenda de pesquisa apontando as possíveis qualificações jurídicas da plataforma online, em razão de sua aproximação de empreendedores e investidores no âmbito do negócio jurídico de compra e venda de oferta pública de valores mobiliários.

English has long been the subject where print text has reigned supreme. Increasingly in our networked and electronically connected world, however, we can be using digital technologies to create and respond to texts studied in English classrooms. The current approach to English includes the concept of ‘multiliteracies,’ which suggests that print texts alone are necessary but not sufficient’ (E.Q, 2000) and that literacy includes the flexible and sustainable mastery of a repertoire of practices. This also includes the decoding and deployment of media technologies (E.Q, 2000). This has become more possible in Australia as secondary students have increasing access to computers and online platforms at home and at school. With the advent of web 2.0., with its interactive platforms and free media making software, teachers and students can use this software to access information and emerging online literature in English covering a range of text types and new forms for authentic audiences and contexts. This chapter is concerned with responding to literary and mediated texts through the use of technologies. If we remain open to trying out new textual forms and see our digital ‘native students’ (Prensky, 2007) as our best resource, we can move beyond technophobia, become digital travellers’ ourselves and embrace new digital forms in our classrooms.

The intersection of current arguments about the role of creative industries in economic development, online user-generated content, and the uptake of broadband in economically disadvantaged communities provides the content for this article. From 2006 to 2008 the authors carried out a research project in Ipswich, Queensland involving local creative practitioners and community groups in their development of edgeX, a Web-based platform for content uploads and social networking. The project aimed to explore issues of local identity and community building through online networking, as well as the possibilities for creating pathways from amateur to professional practice in the creative industries through the auspices of the Website. Set against the backdrop of a rapidly changing technological environment that has problematic implications for research projects aiming to build new online platforms, we present several case studies from the project to illustrate the challenges to participation experienced by people with limited access to, and literacy with, the Internet.

The concept of produsage developed from the realisation that new language was needed to describe the new phenomena emerging from the intersection of Web 2.0, user-generated content, and social media since the early years of the new millennium. When hundreds, thousands, maybe tens of thousands of participants utilise online platforms to collaborate in the development and continuous improvement of a wide variety of content – from software to informational resources to creative works –, and when this work takes place through a series of more or less unplanned, ad hoc, almost random cooperative encounters, then to describe these processes using terms which were developed during the industrial revolution no longer makes much sense. When – exactly because what takes place here is no longer a form of production in any conventional sense of the word – the outcomes of these massively distributed collaborations appear in the form of constantly changing, permanently mutable bodies of work which are owned at once by everyone and no-one, by the community of contributors as a whole but by none of them as individuals, then to conceptualise them as fixed and complete products in the industrial meaning of the term is missing the point. When what results from these efforts is of a quality (in both depth and breadth) that enables it to substitute for, replace, and even undermine the business model of long-established industrial products, even though precariously it relies on volunteer contributions, and when their volunteering efforts make it possible for some contributors to find semi- or fully professional employment in their field, then conventional industrial logic is put on its head.

Blogs and other online platforms for personal writing such as LiveJournal have been of interest to researchers across the social sciences and humanities for a decade now. Although growth in the uptake of blogging has stalled somewhat since the heyday of blogs in the early 2000s, blogging continues to be a major genre of Internet-based communication. Indeed, at the same time that mass participation has moved on to Facebook, Twitter, and other more recent communication phenomena, what has been left behind by the wave of mass adoption is a slightly smaller but all the more solidly established blogosphere of engaged and committed participants. Blogs are now an accepted part of institutional, group, and personal communications strategies (Bruns and Jacobs, 2006); in style and substance, they are situated between the more static information provided by conventional Websites and Webpages and the continuous newsfeeds provided through Facebook and Twitter updates. Blogs provide a vehicle for authors (and their commenters) to think through given topics in the space of a few hundred to a few thousand words – expanding, perhaps, on shorter tweets, and possibly leading to the publication of more fully formed texts elsewhere. Additionally, they are also a very flexible medium: they readily provide the functionality to include images, audio, video, and other additional materials – as well as the fundamental tool of blogging, the hyperlink itself. Indeed, the role of the link in blogs and blog posts should not be underestimated. Whatever the genre and topic that individual bloggers engage in, for the most part blogging is used to provide timely updates and commentary – and it is typical for such material to link both to relevant posts made by other bloggers, and to previous posts by the present author, both to background material which provides readers with further information about the blogger’s current topic, and to news stories and articles which the blogger found interesting or worthy of critique. Especially where bloggers are part of a larger community of authors sharing similar interests or views (and such communities are often indicated by the presence of yet another type of link – in blogrolls, often in a sidebar on the blog site, which list the blogger’s friends or favourites), then, the reciprocal writing and linking of posts often constitutes an asynchronous, distributed conversation that unfolds over the course of days, weeks, and months. Research into blogs is interesting for a variety of reasons, therefore. For one, a qualitative analysis of one or several blogs can reveal the cognitive and communicative processes through which individual bloggers define their online identity, position themselves in relation to fellow bloggers, frame particular themes, topics and stories, and engage with one another’s points of view. It may also shed light on how such processes may differ across different communities of interest, perhaps in correlation with the different societal framing and valorisation of specific areas of interest, with the socioeconomic backgrounds of individual bloggers, or with other external or internal factors. Such qualitative research now looks back on a decade-long history (for key collections, see Gurak, et al., 2004; Bruns and Jacobs, 2006; also see Walker Rettberg, 2008) and has recently shifted also to specifically investigate how blogging practices differ across different cultures (Russell and Echchaibi, 2009). Other studies have also investigated the practices and motivations of bloggers in specific countries from a sociological perspective, through large-scale surveys (e.g. Schmidt, 2009). Blogs have also been directly employed within both K-12 and higher education, across many disciplines, as tools for reflexive learning and discussion (Burgess, 2006).

This case-study explores alternative and experimental methods of research data acquisition, through an emerging research methodology, ‘Guerrilla Research Tactics’ [GRT]. The premise is that the researcher develops covert tactics for attracting and engaging with research participants. These methods range between simple analogue interventions to physical bespoke artefacts which contain an embedded digital link to a live, interactive data collecting resource, such as an online poll, survey or similar. These artefacts are purposefully placed in environments where the researcher anticipates an encounter and response from the potential research participant. The choice of design and placement of artefacts is specific and intentional. DESCRIPTION: Additional information may include: the outcomes; key factors or principles that contribute to its effectiveness; anticipated impact/evidence of impact. This case-study assesses the application of ‘Guerrilla Research Tactics’ [GRT] Methodology as an alternative, engaging and interactive method of data acquisition for higher degree research. Extending Gauntlett’s definition of ‘new creative methods… an alternative to language driven qualitative research methods' (2007), this case-study contributes to the existing body of literature addressing creative and interactive approaches to HDR data collection. The case-study was undertaken with Masters of Architecture and Urban Design research students at QUT, in 2012. Typically students within these creative disciplines view research as a taxing and boring process, distracting them from their studio design focus. An obstacle that many students face, is acquiring data from their intended participant groups. In response to these challenges the authors worked with students to develop creative, fun, and engaging research methods for both the students and their research participants. GRT are influenced by and developed from a combination of participatory action research (Kindon, 2008) and unobtrusive research methods (Kellehear, 1993), to enhance social research. GRT takes un-obtrusive research in a new direction, beyond the typical social research methods. The Masters research students developed alternative methods for acquiring data, which relied on a combination of analogue design interventions and online platforms commonly distributed through social networks. They identified critical issues that required action by the community, and the processes they developed focused on engaging with communities, to propose solutions. Key characteristics shared between both GRT and Guerrilla Activism, are notions of political issues, the unexpected, the unconventional, and being interactive, unique and thought provoking. The trend of Guerrilla Activism has been adapted to: marketing, communication, gardening, craftivism, theatre, poetry, and art. Focusing on the action element and examining elements of current trends within Guerrilla marketing, we believe that GRT can be applied to a range of research areas within various academic disciplines.

This paper will compare and evaluate the effectiveness of commercial media lobbying and advocacy against public service media in two countries, the United Kingdom and Australia. The paper will focus empirically on the commercial media coverage of public service media issues in these countries (relating to the BBC and ABC respectively) over the period since the election of the Conservative-led Coalition in Britain in June 2010, and the election of the Gillard government in Australia in August 2010. Reference will be made to preceding periods as relevant to an understanding of the current environment. In both countries the main commercial media rival to public service media is News Corp and its associated organisations – News Ltd and Sky News in Australia, and News International and BSkyB in the UK. The paper will examine with analysis of print and online news and commentary content how News Corp outlets have reported and commented on the activities and plans of public service media as the latter have developed and extended their presence on digital TV and online platforms. It will also consider the responses of the ABC and BBC to these interventions. It will consider, thirdly, the responses of Australian and British governments to these debates, and the policy outcomes. This section of the paper will seek to evaluate the trajectory of the policy-public-private dynamic in recent years, and to draw conclusions as to the future direction of policy. Particular attention will be devoted to recent key moments in this unfolding dialogue. In Britain, debates around the efforts of News Corp to take over 100% of BSkyB, both before and after the breaking of the phone-hacking scandal in July 2011; in Australia, the debate around the National Broadband Network and the competitive tender process for ABC World, that country’s public service transnational broadcaster; and other key moments where rivalry between News Corp companies and public service media became mainstream news stories provoking wider public debate. The paper will conclude with recommendations as to how public service media organisations might engage constructively with commercial organisations in the future, including News Corp, and taking into account emerging technological and financial challenges to traditional rationales for public service provision.

Enterprise social networks are organizationally bounded online platforms for users to interact with another and maintain interpersonal relationships. The allure of these technologies is often seen in intra-organizational communication, collaboration and innovation. How these technologies actually support organizational innovation efforts remains unclear. A specific challenge is whether digital content on these platforms converts to actual innovation development efforts. In this study we set out to examine innovation-centric content flows on enterprise social networking platforms, and advance a conceptual model that seeks to explain which innovation conveyed in the digital content will traverse from the digital platform into regular processes. We describe important constructs of our model and offer strategies for the operationalization of the constructs. We conclude with an outlook to our ongoing empirical study that will explore and validate the key propositions of our model, and we sketch some potential implications for industry and academia.

The occasional ArtsHub article asking spectators to show respect for stage by switching all devices off notwithstanding, in the last few years we have witnessed an clear push to make more use of social media as a means by which spectators might respond to a performance across most theatre companies. Mainstage companies, as well as contemporary companies are asking us to turn on, tune in and tweet our impressions of a show to them, to each other, and to the masses – sometimes during the show, sometimes after the show, and sometimes without having seen the show. In this paper, I investigate the relationship between theatre, spectatorship and social media, tracing the transition from print platforms in which expert critics were responsible for determining audience response to today’s online platforms in which everybody is responsible for debating responses. Is the tendency to invite spectators to comment via social media before, during, or after a show the advance in audience engagement, entertainment and empowerment many hail it to be? Is it a return to a more democratised past in which theatres were active, interactive and at times downright rowdy, and the word of the published critic had yet to take over from the word of the average punter? Is it delivering distinctive shifts in theatre and theatrical meaning making? Or is it simply a good way to get spectators to write about a work they are no longer watching? An advance in the marketing of the work rather than an advance in the active, interactive aesthetic of the work? In this paper, I consider what the performance of spectatorship on social media tells us about theatre, spectatorship and meaning-making. I use initial findings about the distinctive dramaturgies, conflicts and powerplays that characterise debates about performance and performance culture on social media to reflect on the potentially productive relationship between theatre, social media, spectatorship, and meaning making. I suggest that the distinctive patterns of engagement displayed on social media platforms – including, in many cases, remediation rather than translation, adaptation or transformation of prior engagement practices – have a lot to tell us about how spectators and spectator groups negotiate for the power to provide the dominant interpretation of a work.

This special issue of the International Journal of Technology Policy and Law considers recent developments in the reconfiguration of communication regulation to account for the impact of media convergence. It is readily apparent that media worldwide are going through a series of transformations, associated with the rise of the internet, user-created content and social media. The papers in the collection draw upon legal and policy developments in Australia, the European union and South Korea, and consider such issues as public participation in media policy and regulation, civic media governance for online platforms, the future copyright laws, the roles and responsibilities of internet intermediaries, and regulatory frameworks for internet protocol television (IPTV).
