The main aim of this paper is to examine how the recent themata developments in Social Representations Theory can be linked with the classical process involved in the construction of social representations-anchoring-, as well as with the communicative modalities that are part of the theory since its inception. This was done through a study of the representation of GMOs in the Portuguese press, taken as an opportunity for addressing the issues related to the role played by old categories in rendering new meanings and in establishing new categories. A further objective of the study, more applied in nature, was to explore whether the central characteristics of the representations of biotechnology in European countries were also present in Portugal. All articles that included the expressions Genetically Modified/Genetic Modification/Manipulation or Transgenics, were collected, in five Portuguese newspapers, during the years of 1999, 2000 and 2001. Content analysis of the 239 articles collected showed that their thematical organisation re-constitutes the Red/Green dichotomy found in most European countries. The Red/health discussion is structured around such themata as health/disease, risk/safety, benefits/problems, and anchors in categories like science and progress. The nature /culture opposition emerges, in turn, in the Green/food discussion, which anchors on categories like ideology and employs Propaganda as a communicative modality-a set of indicators configuring a more polemic debate. The conclusions discuss the relevance of linking themata with anchoring and the importance of devising more fine-grained tools for the analysis of Diffusion.

The general characteristics of our patients were similar with other series. Detailed investigation of bronchiectasis is not a standard practice in our outpatient service. These results suggest that the use of a predefined protocol, based on current guidelines, could improve the assessment of these patients and facilitate the achievement of a definitive aetiology.

The level of physical activity (PA) and sedentary behavior (SED) off-training of young athletes may reveal the quality of recovery from training and highlight health related issues. Thus, the aim was to identify and describe young athletes’ PA and SED off-training, according to daily life activities. Eight athletes (15.7 ± 2 years, 1.72 ± 0.6 m height, 62.9 ± 10.2 kg) of a sport talent program wore on their waist a tri-axial accelerometer (ActiGraph® wGT9X-link, Shalimar, FL, USA) at 30 Hz for 15 consecutive days, and reported their schedule. A two-step cluster analysis classified three groups according to sedentary PA and MVPA. The Sedentary (56.9%), presented the highest sedentary PA (mean [CI], 37.37 [36.45–38.29] min/hour); The Hazardous (19.4%) had the lowest values of sedentary and MVPA (10.07 [9.41–10.36] min/hour and 8.67 [7.64–9.70] min/hour, respectively). Balanced (23.7%) had the highest MVPA (28.61 [27.16–30.07] min/hour). Sedentary had the lowest count of home time associated (20%) and higher school (26%) time when compared to the Hazardous (13%). The Balanced showed the highest count of school (61%) and home time (47%). Different profiles for young athletes revealed alarming behavior in the associations with sedentary PA, sitting and SED breaks, which may influence performance and health.

RESUMO: A despeito do uso frequente da mediação humana em museus de ciência há pouco investimento na formação de profissionais para a função. O presente trabalho visa analisar a formação de mediadores em dois museus de ciência, a partir da compreensão dos saberes mobilizados nesse processo. A coleta de dados consistiu na observação de cursos de formação de mediadores, em entrevistas com profissionais atuantes nos processos estudados e questionários autoaplicados com mediadores. A formação de mediadores incluiu cursos organizados pelos museus em questão, mas também a formação acadêmica prévia, a prática e o diálogo entre os mediadores. Os processos estudados envolveram, com ênfases distintas em cada caso, saberes disciplinares, da formação profissional e da experiência, todos essenciais a uma boa prática. Palavras-chave: Museu de ciência. Educação não formal em ciências. Mediação. Formação de mediadores.

There appears to be a beneficial impact of PR on PF in certain groups of patients with bronchiectasis. In addition, PR indications and protocols for patients with bronchiectasis may need to be adapted to accommodate specific patients, so that expressive exercise capacity improvement can be achieved.
