O presente estudo tem como objectivo investigar o reconhecimento e a relevância do papel do Director de Turma enquanto gestor intermédio para os alunos, os encarregados de educação e para os próprios, tendo em conta a interface inter-relacionai em que a função se desenvolve. Este trabalho teve como pressupostos de base a convicção de que a Educação é um fenómeno complexo que, para além de outras, mobiliza dimensões sociológicas, psicológicas e epistemológicas, além de necessitar, constantemente, de reflexão sobre as suas práticas. Assim, conscientes de que o papel do Director de Turma é de grande importância nas organizações escolares, foi nosso objectivo estudá-lo sob o ponto de vista teórico a partir de uma reflexão na prática e efectuar um estudo empírico do modo como a função é percepcionada como elo de ligação entre os Alunos, os Encarregados de Educação e a Escola. Aborda-se a figura do Director de Turma, enquanto gestor pedagógico intermédio da organização escolar, tendo em conta as atribuições que lhe são consagradas na lei e a forma como os demais parceiros vêm a sua função, em especial numa Escola do 2º e 3° ciclos do Ensino Básico, de acordo com as perspectivas/representações dos próprios actores educativos. O estudo visou em concreto, proporcionar uma análise sustentada do reconhecimento e valorização da figura do Director de Turma enquanto mediador entre o aluno, os encarregados de educação e a Escola. Pretendeu-se, nomeadamente, questionar teórica e empiricamente, a interacção e a articulação entre a formação pessoal, a actuação e as representações dos Directores de Turma. Assim, investigou-se de que modo o Director de Turma, considerado como um agente de mediação, é ou não reconhecido e valorizado enquanto figura responsável pela ligação do aluno e do seu encarregado de educação à Escola. Como opção metodológica optou-se por um estudo de caso, recorrendo à complementaridade entre os procedimentos quantitativos e qualitativos, de acordo com os objectivos visados. Assim, as técnicas de recolha de dados utilizados neste estudo foram o inquérito, por questionário, e a entrevista. Estes instrumentos foram sendo sucessivamente aperfeiçoados. Participaram, a nível do inquérito por questionário, duas turmas, uma do 2° ciclo e outra do 3° ciclo (num total de 45 alunos e respectivos encarregados de educação) e a nível da entrevista, os dois Directores de Turma das turmas envolvidas. Procurou-se, deste modo, contribuir para elucidar em que medida a figura do Director de Turma é reconhecida e valorizada como elo de ligação entre os Alunos, os Encarregados de Educação e a Escola enquanto gestor intermédio. Nas Conclusões após o confronto entre as questões de partida, o quadro teórico e os resultados do estudo empírico, discutem-se as dificuldades e limitações que um estudo desta natureza envolve. Avança-se, por fim, com algumas sugestões que a investigação realizada permite, no sentido de utilizar o conhecimento produzido para melhorar o relacionamento entre o Aluno, os Encarregados de Educação e a Escola e, consequentemente, o processo ensino-aprendizagem. ABSTRACT; The purpose of this study is to investigate the recognition and relevance of the role of the classroom director as an intermediate supervisor to the students, the parents and the classroom director himself, having in mind the inner- relation interface the function takes place. This work was conceived on the basic notion that Education is a complex-phenomenon, setting in motion, among other things, sociological, psychological and epistemological dimensions, as well as requiring, frequently, reflection about its practices. Therefore, conscious of the fact that the role of the class director is of enormous importance within a school environment, our aim was to study it from the theoretical point of view by a reflection in practice and performing an empirical analysis on the way it is understood as a link among the students, parents and the school. The role of classroom director is thus analysed as a pedagogical director in a school setting. Taking into consideration the rights conferred to him/her by law and the way all the other partners assign to the class director, particularly in a 2nd and 3rd cycle of the Elementary School system, in accordance with the perspectives/representations of the education actors. More specifically, this study is an in-depth analysis of the recognition and the valuation of the class director figure as a mediator among the pupils, the parents and the school. ln other words, the interaction between theory and practice in the daily performance of the classroom director were questioned and studied for further analysis. Hence, questioned the way in which the classroom director, seen as a mediation agent, could be considered as a coordinator, recognized and valorized as the responsible figure by the linking among the pupil and his/her parents to the school. The case was realized in the 2nd and 3rd cycle of an elementary school in the Alentejo. As a methodological option, quantitative and qualitative processes were both employed, thus keeping in line with the main objective of this work. Therefore, the data collected and herein utilized were the result of queries, i.e., questionnaires and personal interviews. The former were addressed at the pupils of two classes, one of the 2nd cycle and another of the 3rd cycle of the school and their parents (45 pupils and the same number of parents in total), and the two classroom directors of the classes implicated in the study. ln the Conclusion, a balance of the study is presented, comparing the initial research questions, the theoretical framework, and the results of the empirical analysis developed. A few suggestions are presented from the experience gained in this investigation, i.e., using the knowledge acquired in order to improve and enrich the relationship among the pupils, the parents, the school, and the teaching learning process.

Sumário: A morbilidade evitável relacionada com medicamentos (MERM) é um problema de saúde pública com considerável impacto negativo para os doentes e os sistemas de saúde. Os indicadores de MERM constituem medidas operacionais de gestão do risco terapêutico, uma vez que permitem identificar processos de cuidados de saúde que predizem um resultado clínico negativo potencialmente evitável. O uso destes indicadores pode contribuir para reduzir a morbilidade evitável relacionada com medicamentos, evitando danos desnecessários e desperdício de recursos. Objectivo: Desenvolver novos indicadores de MERM para cuidados primários em Portugal a partir da análise de resumos das características de medicamentos (RCM's) e determinar a validade preliminar de face e de conteúdo dos indicadores derivados para este setting. Métodos: A primeira fase deste estudo consistiu num ensaio piloto, com o intuito de testar uma metodologia de inclusão dos RCM's com base na frequência de dispensa da especialidade farmacêutica no ambulatório. Seguidamente procedeu-se ao desenvolvimento de mais indicadores de MERM utilizando a metodologia testada no ensaio piloto. Os indicadores obtidos foram alvo de uma primeira análise com base em aspectos como duplicações e relevância para cuidados primários, de modo a seleccionar os que poderiam passar à fase de validade preliminar de face e de conteúdo. Procedeu­ se então à pesquisa de evidência clínica em fontes de referência para estes indicadores. Na última fase do estudo estes indicadores, bem como a respectiva evidência clínica, foram analisados por um painel de peritos constituído por quatro académicos (dois médicos de família e dois farmacêuticos), sendo aprovados ou eliminados com base num critério de consenso. Resultados: Obteve-se um total de 64 indicadores de MERM, a partir da análise de 35 RCM's. Sujeitaram-se à determinação da validade preliminar de face e de conteúdo 44 indicadores. Foram aprovados por consenso 28 indicadores, tendo sido excluídos 17 (4 por consenso e 13 sem obtenção de consenso). Conclusão: É exequível derivar novos indicadores de MERM para cuidados primários a partir da análise de RCM's. A validade formal de face e de conteúdo destes indicadores obtidos será objecto de estudo de ulterior investigação. /ABSTRACT: Backgroud: Preventable drug-relate morbidity (PDRM) is a public health problem with significant negative impact at a patient and system level. PDRM indicators are operational measures of therapeutic risk management; they identifying processes of care leading to preventable adverse outcomes. The use of these indicators may contribute to tackle preventable drug related morbidity, avoiding unnecessary harm and waste of resources. Objective: To develop new PDRM indicators to Portuguese primary care based on the analysis of summaries of product characteristics (SPC’s) and to determine their preliminary face and content validity to this setting. Methods: Firstly a pilot study was conducted to test a methodology for including SPC's based on the most frequently sold medicines in the ambulatory. Then more indicators were developed using the previously tested methodology. The indicators obtained were analyzed in respect to aspects such as duplications and relevance for primary care to select those that could proceed to the next stage. Clinical evidence was searched for each of these indicators in gold-standard information sources. Finally, this set of indicators and the respective clinical evidence were analysised by a panel of four experts (two academic general practitioners and two academic pharmacists). Preliminary face and content validity was established by means of consensus. Results: A total of 64 indicators was obtained, based on the analysis of 35 SPCs. Forty­ four indicators were subjected to a preliminary assessment of face and content validity, resulting in 28 consensus-approved indicators. Seventeen indicators were excluded (4 rejected by consensus and 13 that did not reach consensus). Conclusion: lt is feasible to derive new PDRM indicators for primary care based on SPC's. The formal face and content validity of the indicators will be determined in a further study.

Despite significant advances in building technologies with the use of conventional construction materials (as concrete and steel), which significantly have driven the construction industry, earth construction have demonstrated its importance and relevance, as well as it has matched in an efficient and eco-friendly manner the social housing concerns. The diversity of earth construction techniques allowed this material to adapt to different climatic, cultural and social contexts until the present time. However, in Angola, the construction with earth is still associated with population fringes of weak economic resources, for which, given the impossibility of being able to acquire modern construction materials (steel, cement, brick, among others), they resort to the use of available natural materials. Furthermore, the lack of scientific and technical knowledge justifies the negative appreciation of traditional building techniques, and the derogatory way how are considered the earth constructions in Angolan territory. Given the country's current development status, and taking into account the environmental requirements and the real socio-economic sustainability of Angola, it is considered that one of the viable and adequate options, could be the recovering and upgrading of the ancestral techniques of earth construction. The purpose of this research is to develop the technical and scientific knowledge in order to improve and optimize these construction solutions, responding to the real problems of housing quality as well as to the current social, economic and environmental sustainability requirements. In this paper, a description of the physical and mechanical characteristics of the adobes typically used in the construction of traditional houses in some localities of Huambo, province in Angola, is carried out. The methodology was based on mechanical in-situ testing in adobe blocks manufactured with traditional procedures: i) tensile strength evaluated with the bending test and compressive strength test on earth blocks specimens; and, ii) durability and erodibility test by Geelong method adopting the New Zealand standard (NZS) procedures (4297: 1998; 4297: 1998 and 4297: 1999). The results allow the characterization of the materials used in the construction of raw earth in the Huambo region, contributing to the development of knowledge of these sustainable and traditional housing constructive solutions with a strong presence in Angola [1, 2]. This study is part of a larger project in the area of Earth Construction [3], which aims to produce knowledge which can stimulate the use of environmental friendly construction materials and contribute to develop constructive solutions with improved performance, durability, comfort, safety and sustainability.

NEW DATA ON THE CHRONOLOGY OF THE VALE DO FORNO SEDIMENTARY SEQUENCE (LOWER TAGUS RIVER TERRACE STAIRCASE) AND ITS RELEVANCE AS FLUVIAL ARCHIVE OF THE MIDDLE PLEISTOCENE IN WESTERN IBERIA Pedro P. Cunha 1, António A. Martins 2, Jan-Pieter Buylaert 3,4, Andrew S. Murray 4, Luis Raposo 5, Paolo Mozzi 6, Martin Stokes 7 1 MARE - Marine and Environmental Sciences Centre, Department of Earth Sciences, University of Coimbra, Portugal: pcunha@dct.uc.pt 2 MARE - Marine and Environmental Sciences Centre, Dep.

The differences in elevation (a.r.b.) of the several terrace staircases results from differential uplift due to active faults. Longitudinal correlation with the terrace levels indicates that a graded profile ca. 200 km long was achieved during terrace formation periods and a strong control by sea base level was determinant for terrace formation. The Neogene sedimentary units constituted the main source of sediments for the fluvial terraces (Fig. 2). Geomorphological mapping, coupled with lithostratigraphy, sedimentology and luminescence dating (quartz-OSL and K-feldspar post-IRIR290) were used in this study focused on the T4 terrace, which comprises a Lower Gravels (LG) unit and an Upper Sand (US) unit. The thick, coarse and dominantly massive gravels of the LG unit indicate deposition by a coarse bed-load braided river, with strong sediment supply, high gradient and fluvial competence, during conditions of rapidly rising sea level. Luminescence dating only provided minimum ages but it is probable that the LG unit corresponds to the earlier part of the MIS9 (ca. 335 to 325 ka), immediately postdating the incision promoted by the very low sea level (reaching ca. -140 m) during MIS10 (362 to 337 ka), a period of relatively cold climate conditions with weak vegetation cover on slopes and low sea level. Fig. 1. Main Portuguese reaches in which the Tagus River can be divided (Lower Tagus Basin): I – from the Spanish border to Arneiro (a general E–W trend, mainly consisting of polygonal segments); II – from Arneiro to Gavião (NE–SW); III – from Gavião to Arripiado (E–W); IV – from Arripiado to Vila Franca de Xira (NNE-SSW); V – from Vila Franca de Xira to the Atlantic shoreline. The faults considered to be the limit of the referred fluvial sectors are: F1 – Ponsul-Arneiro fault (WSW-ENE); F2 – Gavião fault (NW-SE); F3 – Ortiga fault (NW-SE); F4 – Vila Nova da Barquinha fault (W-E); F5 – Arripiado-Chamusca fault (NNE-SSW). 1 – estuary; 2 – terraces; 3 – faults; 4 – Tagus main channel. The main Iberian drainage basins are also represented (inset). The lower and middle parts of the US unit, comprising an alternation of clayish silts with paleosols and minor sands to the east (flood-plain deposits) and sand deposits to the west (channel belt), have a probable age of ca. 325 to 200 ka. This points to formation during MIS9 to MIS7, under conditions of high to medium sea levels and warm to mild conditions. The upper part of the US unit, dominated by sand facies and with OSL ages of ca. 200 to 154 ka, correlates with the early part of the MIS6. During this period, progradation resulted from climate deterioration and relative depletion of vegetation that promoted enhanced sediment production in the catchment, coupled with initiation of sea-level lowering that increased the longitudinal slope. The Vale do Forno and Vale da Atela archaeological sites (Alpiarça, central Portugal) document the earliest human occupation in the Lower Tagus River, well established in geomorphological and environmental terms, within the Middle Pleistocene. The Lower Palaeolithic sites were found on the T4 terrace (+26 m, a.r.b.). The oldest artefacts previously found in the LG unit, display crude bifacial forms that can be attributed to the Acheulian, with a probable age of ca. 335 to 325 ka. The T4 US unit has archaeological sites stratigraphically documenting successive phases of an evolved Acheulian, that probably date ca. 325 to 300 ka. Notably, these Lower Palaeolithic artisans were able to produce tools with different sophistication levels, simply by applying different strategies: more elaborated reduction sequences in case of bifaces and simple reduction sequences to obtain cleavers. Fig. 2. . Simplified geologic map of the Lower Tagus Cenozoic basin, adapted from the Carta Geológica de Portugal, 1/500000, 1992). The study area (comprising the Vale do Forno and Vale de Atela sites) is located on the more upstream sector of the Lower Tagus River reach IV, between Arripiado and Chamusca villages. 1 – alluvium (Holocene); 2 – terraces (Pleistocene); 3 – sands, silts and gravels (Paleogene to Pliocene); 4 – Sintra Massif (Cretaceous); 5 – limestones, marls, silts and sandstones (Mesozoic); 6 – quartzites (Ordovician); 7 – basement (Proterozoic to Palaeozoic); 8 – main fault. The main Portuguese reaches of the Tagus River are identified (I to V). The VF3 site (Milharós), containing a Final Acheulian industry, with fine and elaborated bifaces) found in a stratigraphic level located between the T4 terrace deposits and a colluvium associated with Late Pleistocene aeolian sands (32 to 12 ka), has an age younger than ca. 154 ka but much older than 32 ka. In the study area, the sedimentary units of the T4 terrace seem to record the river response to sea-level changes and climatically-driven fluctuations in sediment supply. REFERENCES Cunha P.
