Hipertexto cooperativo: uma análise da escrita coletiva a partir dos Blogs e da Wikipédia

O artigo tem o objetivo de analisar e discutir as caracteristicas da escrita coletiva, segundo o conceito de hipertexto cooperativo. A partir disso, discute-se como os blogs e a wikipedia (uma enciclopedia digital construida on-line) viabilizam a concretizacao de uma “web viva”, ou seja, redigida e interligada pelos proprios internautas.

Who And What Do Journalism

Technology is typically seen as an instrument that aids journalistic processes. Digital artifacts, however, are seldom considered as active participants. Tautologically, journalism is defined as a practice of journalists. But journalism would not be the same without the role played by technological artifacts. To assess such a problem, this article discusses the ontological contributions from actor-network theory and how they may help to disclose the complex associations between a multiplicity of actors involved in journalism. Besides asking “who” does journalism, we argue that it is also necessary to assess “what” does journalism. We then show how technological actants transform journalistic practices in two recent processes: newsroom convergence and the creation of news by algorithms. Finally, we argue that this new ontology demands epistemological and methodological transformations in journalism studies.

Interação mútua e interação reativa: uma proposta de estudo

A questao da interatividade em ambientes informaticos tem sido tratada de forma elastica e confusa. Nesse sentido, baseando-se em estudos de comunicacao interpessoal, o texto apresenta dois tipos de interacao: a mutua e a reativa. Esses dois tipos interativos sao analisados quanto as seguintes dimensoes: sistema, processo, operacao, fluxo, throughput¸ relacao e interface.

Os blogs não são diários pessoais online : matriz para a tipificação da blogosfera

Blogs were initially defined as online intimate journals. Facing such a reductionist vison, and after discussing the blogosphere’s heterogeneity—including organizational and educational blogs, splogs, flogs and the public or private character of these publications—, this paper presents a matrix for typifying blogs. Based on some analytical dimensions, four groups are proposed: personal and professional (individual blogs); group and organizational (colective).

Para além da emissão sonora : as interações no podcasting

Podcasting e um processo midiatico que emerge a partir da publicacao de arquivos de audio na Internet. Em virtude da minima estrutura tecnologica exigida, a producao e a distribuicao podem ser realizadas de maneira simplificada ate por uma unica pessoa. Ou seja, viabiliza uma producao independente de alcance global. Os podcasts podem nao apenas ser buscados na Internet, como tambem ser assinados (atraves do recurso RSS) para recebimento automatico de novos episodios atraves do uso de um software agregador. Alem do audio, cada programa pode conter imagens, links hipertextuais e ser dividido em capitulos. Dessa forma, ultrapassa-se a mera escuta, oferecendo-se uma experiencia multimidia e formas de navegacao, tanto no interior do programa quanto na rede. O podcasting, no entanto, nao se resume a facil emissao de conteudo na rede e novas formas de recepcao. Como os podcasts sao normalmente vinculados a um blog, a interacao dialogal pode ocorrer entre todos os participantes do processo, borrando a tradicional separacao entre as instâncias de producao e recepcao no contexto massivo. Alem de detalhar as condicoes de producao e recepcao de podcasts, em contraste com o radio, este artigo ainda busca refletir sobre o processo de remediacao entre podcasting e radiodifusao, o potencial desse novo meio enquanto micromidia (Thornton, 1996) e seu impacto na industria fonografica.

Uma análise sistêmica da interação mediada por computador

Apresenta-se uma reviao do sistemismo a partir de autores como Bertalanfty, Morin, Capra, Piaget, Maturana e Varela e da Escola de Pato Alto. A partir disso, conduz-se uma discussao sobre a interacao mediada por computador, tomando-se como partida os tipos de interacao mutua e reativa.

Blogs e seus gêneros: avaliação estatística de 50 blogs em língua portuguesa

Given the increasing variety of blogs and the demand for a method that may typify them, respecting their diff erences, this paper proposes a matrix of 16 blogs genres. Based on this proposal, a statistical evaluation of 5.233 posts, from the 50 most popular Brazilian blogs, is conducted. According to the sample analyzed, it was observed that the organizational and professional blogs are the ones that attract the greatest number

The post as an utterance: Analysis of themes, compositional forms and styles in blog genre studies

The blogosphere’s heterogeneity has significantly increased in recent years. Thus, the blog-as-diary approach has shown its limitations. Viewing blogs as a genre is also misleading, as it confuses medium and genre. Considering that the studies of blog genres still need further theoretical and empirical investigations, we propose a method to assess blog posts, understood as utterances, the minimal unit of a blog. We then conduct an analysis of two large datasets from 100 Brazilian blogs. Three reviewers read and judged 5218 posts from 50 A-list blogs and 1527 posts from 50 non-A-list blogs, captured in a 30-day period. Posts’ compositional form, theme and style were cross-analyzed in and between datasets. Our findings lead to the conclusion that blogs in the A-list group tend to post more and stick to themes that attract audiences. Non-A-list blogs post less and focus on themes of interest to bloggers themselves, not necessarily hype topics.

Seria a multimídia de fato interativa

There is some confusion in the multimedia literature regarding the term interactivity. This term has been used in a free and often inaccurate way. Interaction designates action between entities (interaction - action between).

Interfaces de interação: da potencialidade à virtualidade

There is a great discussion (and why not confusion) about the concept of interactivity. Such a debate deserves special attention from researchers and practitioners who are concerned with educational programs. The precise definition of the concept is of fundamental importance since it guides the construction of interfaces.
