Formação para a literacia da informação: uma interactividade necessária com os media

Our aim is to analyse the relationship between interactive media and its use in Education when applied to formal training for information literacy. Contextualizing the notion of literacy in an evolving framework and emphasizing the recognition of its importance, we highlight some desirable skills in the current information society, including, inevitably, technological competencies. When considering the notion of literacy within an evolving framework and emphasizing the acknowledgement of its significance some desirable skills stand out in the current information society including, inevitably, the technological skills. We emphasize media literacy and select some strategies for teaching and learning practices recommended for the development of new skills, highlighting the contribution of some international literacy standards and describing some of the good practices in Education. We also underline the need for training within an holistic perspective, integrating student’, teachers and staff cooperation in the educational process. In this process, the potential of the Web 2.0, which grants the new information users – the prosumers (consumers and producers) a new statute, new powers and obligations, is indeed worth mentioning. Regarding the situation, we shall quote the reports on the experiences of virtual learning communities that use the moodle platform and mention several activities and programs managed by the Portuguese government to increase the citizens’ literacy’s levels. In conclusion, we point out the need for lifelong learning and the ability of individuals to “learn to learn” who therefore provide literacy with a dynamic component.

A Multi–Agent Brokerage Platform for Media Content Recommendation

Near real time media content personalisation is nowadays a major challenge involving media content sources, distributors and viewers. This paper describes an approach to seamless recommendation, negotiation and transaction of personalised media content. It adopts an integrated view of the problem by proposing, on the business-to-business (B2B) side, a brokerage platform to negotiate the media items on behalf of the media content distributors and sources, providing viewers, on the business-to-consumer (B2C) side, with a personalised electronic programme guide (EPG) containing the set of recommended items after negotiation. In this setup, when a viewer connects, the distributor looks up and invites sources to negotiate the contents of the viewer personal EPG. The proposed multi-agent brokerage platform is structured in four layers, modelling the registration, service agreement, partner lookup, invitation as well as item recommendation, negotiation and transaction stages of the B2B processes. The recommendation service is a rule-based switch hybrid filter, including six collaborative and two content-based filters. The rule-based system selects, at runtime, the filter(s) to apply as well as the final set of recommendations to present. The filter selection is based on the data available, ranging from the history of items watched to the ratings and/or tags assigned to the items by the viewer. Additionally, this module implements (i) a novel item stereotype to represent newly arrived items, (ii) a standard user stereotype for new users, (iii) a novel passive user tag cloud stereotype for socially passive users, and (iv) a new content-based filter named the collinearity and proximity similarity (CPS). At the end of the paper, we present off-line results and a case study describing how the recommendation service works. The proposed system provides, to our knowledge, an excellent holistic solution to the problem of recommending multimedia contents.

A construção da marca visual e os media digitais enquanto temes

A construção de uma marca gráfica, signo que se pretende que identifique e sintetize uma entidade, deve ser consciente dos processos, objectivos e modus operandi que integram o seu contexto e tornam este tema ainda hoje um ponto central no design de identidade e no design de comunicação. Ainda assim, assistimos ao surgir de tendências que vão uniformizando várias marcas que procuram, passe o paradoxo, demarcar-se. Meme é um conceito originalmente publicado pelo biólogo Richard Dawkins (Dawkins, 1989), que significa ‘replicador’, sendo uma teoria alternativa para explicar a evolução humana (uma teoria que não depende dos genes, mas sim da noção de imitação: da noção de ideias que se reproduzem de pessoa para pessoa, quase como um vírus). O conceito vem da palavra grega mimeme e significa ‘aquilo que é imitado’. Este conceito foi desenvolvido por Susan Blackmore no livro The Meme Machine (1999) e, mais recentemente, esta autora introduz a ideia de teme – o meme tecnológico. Como explicar, por exemplo, que a recente imagem gráfica da NOS (2014) seja tão similar à da POV, criada por Paula Scher em 2007? E por sua vez, qual a razão da identidade visual da Optimus (magma, 2008) ser também, em certa medida, idêntica à da Nokia Trends Lab (criado por Greenspace), projecto do mesmo ramo de operação das telecomunicações? No modus operandi do trabalho de design de identidade entram em acção os media digitais, tanto no momento de concepção, como no momento de exibição e fruição das marcas gráficas. Assim, as aplicações, o software transformaram-se numa espécie de silent designers (conceito proposto por Gorb e Dumas em 1987), uma vez que são verdadeiros orientadores da resposta visual a um determinado problema: impulsionam direcções na linguagem visual do design, resultando em soluções semelhantes. Dada esta mudança de paradigmas que as novas tecnologias forjaram no zeitgeist do design, este artigo – baseado em parte da investigação de doutoramento em design – versa sobre a construção da marca gráfica e sobre a análise das categorias visuais que operam em cada signo gráfico da marca, bem como os medias digitais onde elas se inscrevem. Visualmente podemos constatar que as características dos nossos processos de percepção e as características dos meios de criação e transmissão das marcas actuam de forma a aproximar as soluções gráficas, resultando, por vezes, em temes. Com o objectivo de gerar debate académico sobre o tema da sintaxe e da retórica visual da marca gráfica, procuramos identificar e visualizar variáveis estruturais comuns das marcas realizadas com uma linguagem advinda do Estilo Internacional e das marcas mais recentes, digitais, fluídas e em sistema aberto, com a intenção de contribuir para implementar uma literacia visual que descodifique este signo icónico, dentro da actual realidade.

Media e festas de Barrancos: ciclo festivo, férias e um logro

Agosto é um mês de vazio nos locais de azáfama dos restantes onze segmentos de divisão anual. As ruas das grandes cidades mostram uma calma e uma pacatez inabitual. O trânsito automóvel abranda e pacifica, e os transeuntes, mais calmos e menos apressados, circulam com vagar. Os organismos públicos, grande parte das empresas, os mercados de abastecimento, os restaurantes, as escolas quase desertificam. A agitação dos restantes doze meses dispersa-se então principalmente pelas estâncias de veraneio, onde os citadinos se afadigam a descansar. Os jornais, as televisões, as rádios entram numa fase de latência noticiosa, exumando programas que há muito repousavam no descanso dos arquivos, espiando as férias das figuras conhecidas, e trazendo à colação temas «leves» como as roupas da estação. Um ou outro acontecimento, como a morte de uma princesa, a queda de um avião, o afundamento de um submarino, ou os recorrentes incêndios, com a marca do trágico ou do excepcional, são dissecados exaustivamente nos órgãos de comunicação social, que aguardam a rentrée política, assinalada pelos comícios dos partidos parlamentares. Vive-se, em termos noticiosos, um período de escassez. O ciclo anual da vida dos citadinos encontra-se no seu momento mais mitigado, que antecede o retomo às cidades, à azáfama do recomeço de um novo ano, às concentrações junto das prateleiras de material escolar das grandes superfícies, ao congestionamento pendular dos acessos aos centros urbanos, aos apertos nos transportes públicos.

Carotid Intima-Media Thickness and Carotid Plaques Improves Prediction of Obstructive Angiographic Coronary Artery Disease in Women

Does carotid intima-media thickness (cIMT), a surrogate marker of cardiovascular events, have predictive incremental value over established risk factors for stable coronary artery disease (CAD)? Prospective study of 300 patients, with suspected stable CAD, admitted for an elective coronary angiography and carotid ultrasound. The CAD patients had a higher cIMT, which showed a modest predictive accuracy for CAD (area under the receiver-operating characteristic curve 0.638, 95% confidence interval 0.576-0.701, P < .001). The cIMT was an independent predictor of CAD, together with age, gender, and diabetes. C-statistic for CAD prediction by traditional risk factors was not significantly different from a model that included cIMT, carotid plaque presence, or both. However, in women, it was significantly increased by the addition of cIMT or carotid plaque presence. Although cIMT cannot be used as a sole indicator of CAD, it should be considered in the panel of investigations that is requested, particularly in women who are candidates for coronary angiography.

Social Media Integration in Video Games GameNshare: A Social Overlay for Desktop Games

The ever increasing popularity of social media makes it a promising source for the personalization of gameplay experiences. Furthermore, involving social network friends in a game can greatly enrich the satisfaction of the player and also attract potential novel players to a game. This master thesis describes a social overlay designed for desktop games, called GameNshare. It allows players to easily capture and share with multiple social networks game-related screenshots, videos and stories. Additionally, it also provides asynchronous multiplayer game mechanics to directly integrate social network friends in the game. GameNshare was designed to interact with the users in a non-intrusive way allowing them to be in complete control of what is shared. It prevents unsolicited sharing of messages, a key problem in social media integration tools, by the use of built-in message monitoring and anti-spam measures. GameNshare was specially designed for players aged from 18 to 25 years that are regular users of Twitter and Facebook. It was tested by a group of 10 individuals from the target age range that were surveyed to capture their insights on the use of the social overlay. The implemented GameNshare features were well accepted by the testers that were also useful in highlighting features for future development. GameNshare ultimate goal is to make players look and ask for social integration and allow them to take full advantage of their social communities to improve gaming experiences.

Acute Otitis Media a Reliable Warning Sign for Primary Immunodeficiencies?- A Critical Appraisal

Acute otitis media (AOM) is the most common infection in childhood, resulting from both anatomic and immunologic specificities of this age group. Recurrent AOM has been defined as one of the warning signs for primary immunodeficiencies (PID), In this study we evaluated the strength of recurrent AOM as clinical predictor of PID. Methods: Retrospective study (August 2010 - December 2013) which included all patients referred to PID appointment because of recurrent AOM (= 8 AOM episodes/year). Syndromic patients or those presenting with another warning sign for PID were excluded. Clinical, demographic and laboratory results were analized and statistical analysis was made using SPSS 20. Results: Seventy-five patients were included (median age 37,8 months; 62,7% male gender), corresponding to 15% of all first appointments. Other comorbidities were present in 20% of the patients and 17% had ORL surgery prior to PID referral. In most patients, the immunologic screening consisted on the evaluation of humoral function, but in selected cases other studies were performed (namely complement and lymphocyte immunophenotyping). A PID was identified in 12 children (16,0%) and the majority of these patients had other distinctive feature (personal or familiar antecedent of infection or auto-immunity, 66,7%, p<0,05). Nine children (12,0%) underwent prophylactic cotrimoxazole. The average length of follow-up was 11,2 months. Conclusion: Despite being a very frequent cause of immunologic screening, in this study recurrent AOM was not found to be a good predictor of underlying PID, unless the patients presents other significant personal or family history.
