Educação alimentar infantil: potencialidades de estudantes de educação de infância

Resumo: Na promoção de comportamentos alimentares saudáveis ao longo da vida. que deve iniciar-se o mais precocemente possível, a educação alimentar é um elemento chave. O jardim-de-infância é um espaço efectivo na implementação de projectos de educação alimentar, onde os educadores de infância são actores imprescindíveis. Este estudo teve como objectivo desenvolver uma metodologia apropriada para identificar as capacidades de estudantes de educação de infância e avaliar as suas aptidões no contexto da educação alimentar infantil. A população alvo do estudo foram estudantes do 4ºano da licenciatura em educação de infância de instituições públicas e privadas da área metropolitana de Lisboa (n=287). Construiu-se um videograma, integrador dos domínios da aprendizagem (cognitivo e afectivo) e dos factores associados aos comportamentos em saúde (predisponentes, capacitadores e de esforço). A construção dos questionários estruturou-se em: conhecimentos-atitudes-comportamentos.Pretendia-se que os estudantes transmitissem a sua opinião, de acordo com os questionários.Os estudantes manifestaram conhecimentos, no âmbito da alimentação infantil e da utilidade e aplicabilidade da educação alimentar.Nenhum estudante apresentou conhecimentos negativos, numa escala de zero a 18 valores, 86,9% obtiveram uma classificação entre 11 e 17 valores e 13,1% a classificação máxima.A atitude dos estudantes revelou-se consensual com o desejável, 98,5% apresentaram atitudes positivas face aos aspectos estruturadores das actividades de educação alimentar.No domínio do "saber fazer" 51,0% dos estudantes demonstraram fragilidades no seu desempenho/comportamento. Em conclusão, a utilização do questionário demonstrou ser apropriado para a medição dos conhecimentos, das atitudes e como forma de os estudantes, após visionarem o videograma, espelharem o seu desempenho/comportamento face à representação do educador de infância. A taxa de resposta nunca foi inferior a 98,9% (n=284). No domínio dos conhecimentos, os estudantes manifestaram concepções positivas no campo da alimentação infantil e da educação alimentar. As atitudes enfatizaram-se no domínio afectivo, nos aspectos relacionais e comunicacionais. No domínio dos comportamentos, 91,8% dos estudantes apresentaram dificuldades na identificação dos aspectos menos correctos do desempenho dos actores do video, o que pode sugerir lacunas no âmbito do "saber fazer". Abstract:Nutrition education is key element to promote lifelong healthy eating behaviours and it must begin since early stages of life. Nursery schools are an effective space in the implementation of nutrition education projects, where the nursery teachers are indispensable actors. The aim of this study was to develop an appropriate methodology to identify nursery education student´s skills and evaluate their attitudes in the childhood nutrition education's context. The study's population were students of the 4th degree in private and public nursery education universities in Lisbon metropolitan area (n=287). A video integrator of learning domains (cognitive and affective) and of factors associated with health behaviours (predisposing, enabling and reinforcing) was developed. Questionnaire´s construction was structured in: knowledge-attitudes-behaviours.According to the questionnaires students were asked to transmit their opinion. Students revealed knowledge, in the scope of the childhood nutrition and in utility and applicability of nutrition education. No students presented negative results in knowledge ina zero - 18 scale; 86,9% students obtained a classification between 11 and 17 and the maximum classification was obtained by 13.1% students. Student's attitude was according to win the desirable, 98,5% student´s revealed positive attitudes in the nutrition education's structure aspects of chilhood activities.In the domain of the "know to do" 51,0% of students showed fragilities in their performance/behaviour. In conclusion, the questionnaire´s utilization confirm to be appropriated in measurement knowledge and attitudes and also, after watching the video, as a way for students reflect their performance/behaviour face to the nursery teacher´s representation. Answer´s rate was never lower than 98.9% (n=284). In the knowledge's domain students demonstrated positive conceptions in the childhood nutrition and nutrition education's fields. Attitudes were emphasized in the effective domain in the communication and relational aspects. In behaviour's domain 91.8% students presented difficulties in identifying the less correct aspects of the video actor's performance what may suggest gaps in the "know to do" scope.

Reinterpretation de l'Histoire Stratigraphique et Tectonique de la Structure de Serra de El-Rei (Portugal)

Les travaux faits sur le terrain et les interprétations cartographiques de ces dernières années, montrant la pertinence des observations de Paul Choffat au siècle dernier, permettent de préciser l'échelle stratigraphique et de mieux distinguer les phases de l'histoire tectonique de la structure de Serra de EI-Rei. En attendant la publication d'une cartographie très détaillée mettant en évidence le détail des déformations tectoniques, il faut souligner la dissymétrie des deux flancs de cette structure ainsi que le rôle de certaines failles transverses. Sur son flanc nord, la série liasique, allant des dolomies du Lias inférieur au Toarcien inférieur ou moyen, est recouverte stratigraphiquement et en légère discordance par le "Lusitanien" qui remanie à sa base des éléments du Toarcien inférieur ou moyen. Sur son flanc sud, dans la partie centrale, la série stratigraphique liasique est comparable à celle de l'autre flanc, mais les dépôts du Toarcien, plus complets, sont affectés au cours de la zone à Meneghinii par des perturbations synsédimentaires avec fossiles brisés et/ou remaniés et des réductions d'épaisseur. Plus à l'Est, le Toarcien est très réduit et (tectoniquement?) en contact avec le Dogger. Au Sud-Ouest en revanche, prés de Bolhos, la série toarcienne est plus complète et couronnée par l'Aalénien inférieur, mais tronquée par un contact oblique N-S, repris par la tectonique récente. Sur ce flanc, le Bajocien inférieur est représenté mais peu épais; il est suivi par le Bajocien supérieur, le Bathonien et le Callovien très développés qui sont recouverts par un "Lusitanien" épais, très différent de celui du flanc nord. Cette série du Jurassique moyen et supérieur a été décrite dans la thèse de Christiane Ruget (1963). La structure de Serra de EI-Rei constitue une sorte de raccord E-W entre les importantes structures (diapiriques ?) méridiennes de Caldas da Rainha au NE et de Bolhos au SW. II s'agit d'une structure de tectonique distensive, en demi-graben, d'âge jurassique, qui est responsable de la dissymétrie des séries lithostratigraphiques sur ses deux flancs; au Miocène, pendant la compression bétique, cette structure a subi une inversion en constriction. Un modèle de l'évolution sédimentaire du secteur est présenté.

Development of an integrative approach for the characterization of ecological risk on marine transition ecosystems: the Sado Estuary as a case study

Estuaries and other transitional waters are complex ecosystems critically important as nursery and shelter areas for organisms. Also, humans depend on estuaries for multiple socio-economical activities such as urbanism, tourism, heavy industry, (taking advantage of shipping), fisheries and aquaculture, the development of which led to strong historical pressures, with emphasis on pollution. The degradation of estuarine environmental quality implies ecologic, economic and social prejudice, hence the importance of evaluating environmental quality through the identification of stressors and impacts. The Sado Estuary (SW Portugal) holds the characteristics of industrialized estuaries, which results in multiple adverse impacts. Still, it has recently been considered moderately contaminated. In fact, many studies were conducted in the past few years, albeit scattered due to the absence of true biomonitoring programmes. As such, there is a need to integrate the information, in order to obtain a holistic perspective of the area able to assist management and decision-making. As such, a geographical information system (GIS) was created based on sediment contamination and biomarker data collected from a decade-long time-series of publications. Four impacted and a reference areas were identified, characterized by distinct sediment contamination patterns related to different hot spots and diffuse sources of toxicants. The potential risk of sediment-bound toxicants was determined by contrasting the levels of pollutants with available sediment quality guidelines, followed by their integration through the Sediment Quality guideline Quotient (SQG-Q). The SQG-Q estimates per toxicant or class was then subjected to georreferencing and statistical analyses between the five distinct areas and seasons. Biomarker responses were integrated through the Biomarkers Consistency Indice and georreferenced as well through GIS. Overall, in spite of the multiple biological traits surveyed, the biomarker data (from several organisms) are accordant with sediment contamination. The most impacted areas were the shipyard area and adjacent industrial belt, followed by urban and agricultural grounds. It is evident that the estuary, although globally moderately impacted, is very heterogeneous and affected by a cocktail of contaminants, especially metals and polycyclic aromatic hydrocarbon. Although elements (like copper, zinc and even arsenic) may originate from the geology of the hydrographic basin of the Sado River, the majority of the remaining contaminants results from human activities. The present work revealed that the estuary should be divided into distinct biogeographic units, in order to implement effective measures to safeguard environmental quality.
