Schools are ideal settings to promote adolescent physical activity (PA), yet school-based interventions have shown limited long-term impact. This position paper presents key issues surrounding school-based PA interventions. Collaborative conceptual thinking drawing on multi-author expertise and available evidence advanced our understanding and opinion. Key arguments: 1) the adoption of a systems approach, which maximizes partnership action and leverages policy, is crucial for understanding the complexities of implementing whole-school programs; 2) a reorientation to an assets perspective optimizes existing strengths and resources allowing greater emphasis on the full range of physical, cognitive, emotional and social benefits that PA provides, and 3) a move beyond traditional positivist research designs to advance our knowledge of what works better, for whom and in what context is needed for greater progress We provide suggestions, specifically advocating for systems approaches, as a realistic way to improve how we support PA in schools in the future.

The present research compared the knowledge of primary school children and pre-service primary teachers about various native mammals of the Iberian Peninsula (IP-Portugal and Spain) and the African Savannah. For this purpose, a questionnaire was administered to 420 children and 215 pre-service teachers from these countries asking for the identification of animals through photos and whether they had native status on the IP. The pre-service teachers performed better than the children. The Savannah animals were better identified than those of the IP. The results were similar in both countries, even though the Spanish performed a little better. Children from both countries had more difficulty identifying the native status of the animals, with a high percentage of them thinking that Savannah animals lived in the wild on the IP. This error was less frequent among the pre-service teachers but, even so, with a percentage for certain animals that can be considered of concern. This issue is absent in the training courses in both countries, a conclusion based on an analysis of the syllabuses. The importance of improving knowledge of native fauna though formal and informal learning is discussed as a way to promote a conservationist attitude with direct repercussions on the recognition of the importance of local or regional biodiversity.

The present study compared Portuguese and Spanish children in the 6th year of primary school in terms of their knowledge and live experience of animals from the Iberian Peninsula (IP) and the African savannah. A questionnaire was administered to 420 children from state schools, 215 from Portugal and 205 from Spain. The questionnaire included photos of eleven mammals from each region. The pupils had to identify them, to say if they had observed them live and where, and if they are native in the IP. The results showed a greater knowledge of both groups of the savannah species, also the ones most had seen live. However, the Spanish children had a better performance in the identification of the native mammals and which animals are native on IP, probably because these children are from a less urban zone, with more direct contact with some of the species presented. The school does not seem to play, in either group, an important role in the learning about native species. Boys from both countries performed better than girls on the issues under study. A high percentage of children from both countries think that several of the savannah species occur wild on the IP.

The main aims of this study were to investigate the relationship between the lexical size and the emergence of morphological and syntactic markers in toddlers between the ages of 16 and 30 months and to compare these results between Galician and European Portuguese. Parents of 3012 Portuguese toddlers and those of 1081 Galician toddlers completed the MacArthur-Bates Communicative Development Inventory: Words and Sentences. The results indicated that the number of words, the ability to combine words and the number of different morphemes produced increased with age. The ability to combine words was used as an indicator of syntactic development; this ability was also associated with the toddlers' lexical size. In both samples, gender morphemes seemed to be the first to have their production generalized, followed by the plural and the past participle. The production of gender morphemes was accompanied by a small lexical size, whereas the imperfect tense and the person mark onset were associated with large lexical sizes. The implications of these results for charting the continuity between lexical, morphological and syntactical development are discussed.

This paper examines the relation between department affiliation and interdisciplinarity in terms of knowledge creation. While the claims made for the benefits or limitations of interdisciplinarity are diverse, they have been largely related to modes of academic governance or to the bare nature of disciplines. Less is known on the precise role of social networks in fostering or hindering interdisciplinarity within intraorganizational contexts. Thus, to explore the influence of network structure, tie strength and nodal properties in interdisciplinarity within higher education institutions, we study the structure and dynamics of academic's personal knowledge networks. It is used a mixed methods approach combining the delineation of personal networks with the ties' content analysis regarding a conceptual model specifically developed for this study. Personal network data were collected and semi-structured interviews were held with 32 academic staff members of the academic and research system in Catalonia, Spain. Findings suggest that belonging to a department decreases interdisciplinarity and that institutional constraints are more significant than the strength of the ties. Researcher's network centrality and strength of ties are positively related to interdisciplinarity. Structural holes control for certain organizational rewards and individual attributes but are not directly linked to interdisciplinarity. [ABSTRACT FROM AUTHOR]

The article examines water-sediment quality in an agricultural zone of a protected area within the Tagus River basin district in central Portugal. During four sampling occasions, 4 herbicides, 2 insecticides and the metabolite 3,4-dichloroaniline were detected in surface water samples at four sites and in groundwater samples from six wells. Measured concentrations were compared with parametric values for human consumption, groundwater quality standards, and environmental quality standards applicable to surface water set in European Union legislation. Most severe adverse effects were found on the growth of the algae Pseudokirchneriella subcapitata and lethality of the crustacean Daphnia magna in nondiluted water samples.
