Résumé I (Pratiques Pédagogiques)- Ce compte-rendu du stage réalisé pour ma deuxième année de master rapporte le résultat de l’observation des cours donnés à trois élèves de niveaux différents par le professeur de harpe de l’Ecole de Musique « Nossa Senhora do Cabo » à Linda-a-Velha, commune de Oeiras, située près de Lisbonne. Grâce à l’activité du professeur, et par le suivi de l’évolution de ses élèves tout au long de l’année scolaire 2012-2013, tant sur le plan technique que sur le plan musical, j’ai pu participer à toutes les étapes de leur apprentissage et retrouver quelques principes pédagogiques fondamentaux. Ainsi, j’ai constaté la nécessité d’une organisation didactique solide dans la définition d’objectifs, la planification du travail, le choix des méthodes d’étude, mais souple par la régulation des rythmes d’apprentissage et des techniques d’acquisition. La métacognition est aussi une notion composante essentielle de la pratique du professeur, dont un des grands objectifs est de développer chez ses élèves la capacité de se prendre en charge seul. J’ai également apprécié l’importance de l’aspect relationnel intrinsèque à toute situation d’apprentissage, ainsi que celle de la connaissance des théories de la motivation, atout important permettant d’agir au niveau psychologique sur les élèves et d’obtenir à plus ou moins long terme des changements comportementaux influents sur la qualité de ces apprentissages. J’ai enfin essayé de dégager différents types d’approches pédagogiques possibles, parmi les stratégies observées chez le professeur, ainsi que d’après quelques éléments de réflexion personnelle.

The reef levels of the gulf of Skoura belong to the reef formation of the Upper Miocene of the South-Rifan straits. A detailed analysis of the vertical distribution of various forms of colonies has led to the establishment of precise coral morphologies zonation. This palaeoecological approach leads us to distinguish between two environments in the Skoura gulf, probably corresponding to two reef episodes. The palaeogeographical implications (relationships between the Atlantic ocean and the Mediterranean sea) will be pointed out.

The Aquitaine Basin (southwestern France) is known since long ago for its richness in marine miocene deposits of various facies. A few stratotypes concerning this period have been described in the investigated area. The stratigraphical framework has been recently revised and the study of new exposures completes our knowledge on these levels. In the present work, the authors produce a biostratigraphical distribution of about 160 species (larger and smaller foraminifera), found in the surface exposures of Aquitaine, from the topmost Oligocene (Chattian) through to Middle Miocene (including Serravallian). As a rule, the common species without significant ranges have not bcen mentioned. The microfaunas of several exposures have been thoroughly revised, which has allowed to precise the distribution of many species and induced a few modifications of the results previously produced. Synonymy problems and new taxonomical revisions have been taken into account. Of course, this work will be probably submitted to some changes according to new research on the already known exposures or other more recently discovered.

Abundant crops of Glycymeris have been made in the neritic bioclastic deposits of the Aquitaine Basin. After an outline about the Chattian taxa, the 5 Lower Miocene lineages are presented; G. cor is plainly predominant. Then, the Middle Miocene faunas are also detaiIed, G. inflatus and G. bimaculatus being the most frequent taxa. A test of biometrical analysis about the G. cor species is presented.

Le test ELISA-TÉTANOS (Biosys, France) a été utilisé pour le titrage des anti-corps tétaniques (sensibilité = 0,0025 UI/ml) en sérums humains de donneurs de sang, 566 hommes et 108 femmes, âges de 18 à 58 ans, moyenne de 29 ans, provenant de São Paulo, SP, Brésil. L'OMS, acceptant seulement la séroneutralisation sur souris (NT), la méthode de référence, pour les études sur la protection contre le tétanos, préconise le titre de 0,01 UI/ml comme minimum protecteur. BOURLEAUD & HUET ont proposé la limite de 0,06 UI/ml quand s'emploie le test ELISA, en attendant à une certaine discordance inévitable entre les méthodes. Parmi les 674 sérums étudiés, 178 (26,41%) n'ont pas présenté d'anticorps (< 0,0025 UI/ml); 413 (61,28%) ont présenté des résultats égaux ou supérieurs à 0,01 UI/ml et en 232 (34,42%) les titres ont été égaux ou supérieurs à 0,06 UI/ml. Le pourcentage d'individus protégés a été inversement proportionnel à 1'âge: environ 50% dans le groupe le plus jeune (hommes de 18 à 35 ans et femmes de 18 à 23 ans) contre environ 10% dans le groupe de plus de 42 ans ont présenté des titres sûrement protecteurs (> 0,06 UI/ml).

A fragment of the lower jaw of cuon (Cuon alpinus europaeus BOURGUIGNAT, 1868) found at gruta do Escoural is studied. It is the first occurrence recorded for the Pleistocene of Portugal.

For the first time, small mammals were found at the earliest marine level in the northeastern part of the lower Tagus basin, to the NE of Lisbon. At this new locality, at the 10 kilometer of the Lisbon-Oporto A1-IP1 highway,conglomerates yielded, along with marine fossils, more or less abraded teeth and bones from insectivores,lagomorphs, rodents and small artiodactyls (sec Tableau 1). Age may he ascribed to the lower Miocene, MN 2b Neogene mammal unit (about 22 My), but an early MN 3 age cannot be entirely excluded. That corresponds to latest Aquitanian (or less probably earliest Burdigalian) (sec Tableau 2). This is the first hitherto found locality with small mammals of this age as far as Portugal is concerned, as well as the oldest locality so far known in the Tagus basin. Km 10 is somewhat older than the localities of Universidade Católica and Avenida do Uruguay in Lisbon (ANTUNES & MEIN, 1986). Hence we can rather accurately date the age of the first marine transgression in the northeastern part of the lower Tagus basin. This shows that in this region there are no marine equivalents of the "Venus ribeiroi beds" (Aquitanian,Division 1 of the Lisbon Miocene series). Correlation between this unit and the uppermost levels of the essentially paleogene "Complexo de Benfica" may be possible. Fossils at km 10 point out to shallow, coastal, highenergy marine environments. Sedimentological features are compatible with this model. Dry land and swamps with brackish (or ev en fresh) waters were present nearby. From those areas came remains of mammals, crocodylians, as well as oysters and charophytes that were later transported to the sea. Sea was warmer than the extant Atlantic at the same latitudes, even if conditions were not strictly tropical then. These conditions surely influenced climate in the nearby regions. Ecological data concerning mammalian faunas distinctly point out to nearby forest-rich environments, much more so than for Universidade Católica and Avenida do Uruguay localities, from where drier, even steppe environment forms largely prevail.
