This article considers the impact of the WikiLeaks organisation in relation to debates around the defence of national security and free speech, global media citizenship and the emerging dynamics of the global public sphere. Building on the author’s previous work on political communication, journalism and ‘cultural chaos’, it explores the implications of WikiLeaks for emerging conceptions and definitions of journalism, and for the changing structure of media–politics power relations at the global level, against the background of three trends: democratisation, declining deference and digitalisation.

There is a category of film about journalism in which journalism is not the star, but the supporting player, and journalists not the protagonists but the Greek chorus, commenting on and also changing the realities they report. In such films the news media are a structuring presence driving the plot, shaping the narrative, constructing what we might think of as a pseudo-reality. Like Daniel Boorstin’s notion of the pseudo-event (introduced in his still-relevant book The Image, 1962), this pseudo-reality is so-named because it would not exist were it not for the demands of the news media’s hunger for stories, and knowledge of the damage they can do with those stories, on the calculations and actions of the key actors. Pseudo-realities form as responses to what political actors think journalists and their organisations need and want, or as efforts to shape journalistic accounts in ways favourable to themselves. Films about politics often feature pseudorealities of this kind, in which the events and actions driving the plot have only a tenuous relationship with important things going on in the everyday world beyond the political arena. Everything we see is about image, perception, appearance.

This study demonstrates how to study fashion journalism from the point of view, that it is its own field of journalism, akin to other journalism beats such as politics, sports and health. There is scope here for comment on the co-evolution of fashion and journalism, leading to ‘fashion journalism’ developing as a distinct field of study in its own right. This research contributes more generally to the field of media and cultural studies, by developing the threepart producer/text/reader model, which is the standard ‘media studies’ analytical framework. The study of fashion media from a cultural studies perspective acknowledges that cultural studies has pioneered the formal study of both journalism and fashion, for instance in studies of women’s magazines; but it has not brought the two areas together sufficiently. What little work has been done, however, has allowed theorists to explore how magazines promote feminism and form culture, which acts as a step in concreting fashion’s importance theoretically. This thesis has contributed to cultural studies by showing the relationship between the corporate industry, of both fashion and media (producer), and the active audience (reader) can be rethought and brought up to date for the more interactive era of the 21st century.

Australia’s mainstream media landscape has long been recognised as highly limited – media ownership in the country has traditionally been concentrated in the hands of a very few, and (except for Sydney and Melbourne) it is common for major Australian cities to be served by only one local newspaper, usually produced by Rupert Murdoch’s News Ltd. This can be seen also to affect the quality and diversity of Australian journalism; additionally, the global decline of newspaper publishers’ revenues and overall adverse economic conditions exert further pressure on journalistic operations in the country. At the same time, and possibly in response to the increasing stresses on industrial journalism in the country and the implications they have for the quality of journalistic products, a vibrant and dynamic ecosystem of Australian industrial and citizen journalism publications has emerged online. Existing media organisations have built strong news brands online, while citizen journalists and political bloggers have given voice to issues, concerns, and opinions hitherto underrepresented in Australian mainstream journalism; of particular interest, however, is the increasing level of engagement and interaction between the two. While such interaction has been characterised by deep animosity at times (especially also in the context of the Australian federal election in November 2007), Australia has also seen the emergence and establishment of a number of new, intermediary online publications which act as spaces for public debate and analysis – from the public intellectualism of Online Opinion through the muckraking of Crikey to the progressive politics of New Matilda. The rise of social media as spaces for the discussion of news and politics further changes the media environment, potentially leading both to renewed conflict between professional and citizen journalists and to a greater level of engagement between journalists and audiences. Overall, then, such online developments offer a chance for a greater diversity of opinion and representation in Australian journalism, but also remain under a cloud from uncertain long-term business models and funding arrangements. This chapter outlines current trends in Australian online journalism, and speculates about their effect on the Australian news media landscape.

Oprincipal objetivo desse artigo é apresentar os resultados parciais de uma pesquisa em andamento sobre o processo de produção de conteúdo do portal Viva Favela, um dos projetos sociais realizados pela organização nãogovernamental Viva Rio. Partindo de uma abordagem conceitual que discute os modos pelos quais a mídia alternativa e o jornalismo público/jornalismo cívico criam as condições de possibilidade para que uma determinada prática jornalística dê ‘voz’ e ‘empodere’ (empower) moradores de periferias e favelas brasileiras, estamos realizando um estudo das rotinas produtivas do Viva Favela e seus ‘correspondentes comunitários’. O conceito sobre voice, de Jo Tacchi, oferece-nos um embasamento teórico adequado para refletirmos sobre o que vem sendo denominado, nos Estados Unidos, de digital storytelling – as narrativas digitais produzidas com as tecnologias de informação e comunicação para “contar estórias” 1, que são criativamente apropriadas, no Brasil, por moradores das favelas e periferias das regiões metropolitanas.

EM artigo anteriormente publicado (AGUIAR, 2008a), concluímos que as críticas elaboradas por certos autores (SOUSA, 2000; KURTZ, 1993; MARSHALL, 2003; MARCONDES FILHO, 1988), ao classificarem um determinado modo de jornalismo como sensacionalista, parecem querer opor uma imaginária constituição democrática do espaço público e da cultura legítima a uma suposta disfunção narcotizante do entretenimento, que promoveria o conformismo social e reforçaria as normas sociais. O jornalismo sensacionalista, nesse entendimento, veicularia apenas a ampla trivialidade e o excesso de diversão estaria “matando” os ideais iluministas da sociedade moderna, tal como aposta Postman (1986). Entretanto, pode-se ver nestas críticas aquilo que Edgar Morin define, ao estudar cultura de lazer, como a má impressão causada pelo divertimento e pela evasão aos “moralistas dessa confederação helvética do espírito que são as letras e a universidade” (MORIN, 2002).

Resumo: A proposta do artigo é discutir a possibilidade de um jornalismo não-retórico, pelo viés do acontecer poético, no romance-reportagem Abusado: o dono do morro Dona Marta, do jornalista Caco Barcellos. Retoma, nesse empreendimento, a reflexão do filósofo Michel Foucault sobre a construção discursiva da figura do delinquente. Com isso, a construção biográfica do traficante Márcio Amaro de Oliveira aparece como imagem-questão, anunciadora de novas perguntas e inquietações sobre a realidade da favela da Santa Marta, ao invés de uma simples construção discursiva sobre o real.

The feasibility of using an in-hardware implementation of a genetic algorithm (GA) to solve the computationally expensive travelling salesman problem (TSP) is explored, especially in regard to hardware resource requirements for problem and population sizes. We investigate via numerical experiments whether a small population size might prove sufficient to obtain reasonable quality solutions for the TSP, thereby permitting relatively resource efficient hardware implementation on field programmable gate arrays (FPGAs). Software experiments on two TSP benchmarks involving 48 and 532 cities were used to explore the extent to which population size can be reduced without compromising solution quality, and results show that a GA allowed to run for a large number of generations with a smaller population size can yield solutions of comparable quality to those obtained using a larger population. This finding is then used to investigate feasible problem sizes on a targeted Virtex-7 vx485T-2 FPGA platform via exploration of hardware resource requirements for memory and data flow operations.

This study makes out the case for the use of the Conversational Analytic method as a research approach that might both extricate and chronicle the features of the journalism interview. It seeks to encourage such research to help inform understanding of this form and to provide further lessons as to the nature of journalism practice. Such studies might follow many paths but this paper focuses more particularly on the outcomes for the debate as to the continued relevance of "objectivity" in informing journalism professional practice. To make out the case for the veracity of CA as a means through which the conduct of journalism practice might be explored the paper examines: the theories of the interaction order that gave rise to the CA method; outlines the key features of the journalism interview as explicated through the CA approach; outlines the implications of such research for the establishment of the standing of "objectivity". It concludes as to the wider relevance of such studies of journalism practice for a fracturing journalism field, which suffers from a lack of benchmarks to measure the public benefit of the range of forms that now proliferate on the internet.

Motivation: Unravelling the genetic architecture of complex traits requires large amounts of data, sophisticated models and large computational resources. The lack of user-friendly software incorporating all these requisites is delaying progress in the analysis of complex traits. Methods: Linkage disequilibrium and linkage analysis (LDLA) is a high-resolution gene mapping approach based on sophisticated mixed linear models, applicable to any population structure. LDLA can use population history information in addition to pedigree and molecular markers to decompose traits into genetic components. Analyses are distributed in parallel over a large public grid of computers in the UK. Results: We have proven the performance of LDLA with analyses of simulated data. There are real gains in statistical power to detect quantitative trait loci when using historical information compared with traditional linkage analysis. Moreover, the use of a grid of computers significantly increases computational speed, hence allowing analyses that would have been prohibitive on a single computer. © The Author 2009.
