Media Education and Brazilian Educational Policies for the Enhancement of Learning

As media education concepts and practices have been disseminated and strengthened in European countries and Americas, the policies responsible for that expansion remain little known, particularly in countries where the achievements have been recently noted. That is the case for Brazil, where there have been new opportunities for media education, considered as a valuable resource to help accomplish goals of the educational system. This paper looks into the contribution of media education to the enhancement of teaching and learning in the context of innovations brought by recent policies of the Brazilian Ministry of Education. After educational reform programmes which brought the opportunity for emerging fields such as media education, we produced teaching material and conducted a series of workshops with students and teachers from state secondary schools. By reading and producing multimedia information about local public services available to young people, pupils learned about democracy, citizenship, civic engagement, media language, and identity. Lessons from our experiment are discussed against the backdrop of education policies being implemented to ameliorate harsh conditions resulting from the recent economic crisis. We suggest that media education can help by creating a learning environment in which the students become aware of the value of educational attainments.

A phylogenetic analysis of the Cryptocarya group (Lauraceae), and relationships of Dahlgrenodendron, Sinopora, Triadodaphne, and Yasunia

A phylogenetic analysis based on nuclear ITS and plastid trnK intron sequences confirms that Dahlgrenodendron, Sinopora, Triadodaphne, and Yasunia are members of the Cryptocarya group, as expected from morphology. Dahlgrenodendron from South Africa is sister to Aspidostemon from Madagascar. Triadodaphne inaequitepala is nested within Endiandra (both from Australasia), and Yasunia from South America is nested among South American Beilschmiedia species. Sinopora is a member of the Beilschmiedia clade, but its precise position is still uncertain. Among large genera of the group, Cryptocarya is clearly monophyletic, and Endiandra appears to be as well, if T. inaequitepala is included. Beilschmiedia is paraphyletic with respect to (at least) Potameia and Yasunia. Most well-supported clades within genera are geographically homogeneous, except a clade including the Chilean Cryptocarya alba and two New Caledonian species. Both Beilschmiedia and Cryptocarya have reached the Americas more than once. Four-locular anthers are plesiomorphic in the Cryptocarya group; two-locular anthers have arisen by fusion of the two pollen sacs of a theca. In the plesiomorphic fruit type, the ovary is completely enclosed in receptacular tissue; a superior fruit, seated free on its pedicel, is a synapomorphy of the Beilschmiedia clade.

O ensino da açao de ler e suas contradiçoes

The article broaches the diffi culties found by the Brazilian school on teaching the act of reading to students in the beginning of their scholarship process. In order to analyze those diffi culties, one must start from the assumption that, historically, this teaching fi nds mostly basis on the emphasis on the fl uent pronounce without considering the reader’s intention to achieve meaning before the text, in social, historic and cultural situations. On this perspective, the school usually teaches students how to dominate some of the aspects of the linguistic system, for not comprehending that the act of reading is a cultural, plural, historical and social action, that uses this system. The article concludes that Latin America’s education has a path to run: the one to learn to teach the act of reading as a cultural practice, instead of simply understanding it as the domain of the linguistic system basis.

Anotação de 500 ESTs da saúva Atta laevigata

Leaf-cutting ants belonging to the genus Atta occur from the tropical to subtropical regions of the Americas. These insects are considered pests because they cause serious damage in agricultural areas. Among these, stands out Atta laevigata, species which the colony requires a huge amount of leaves to grow its symbiotic fungus which is the main food source of the nest. Thus, the study of the transcriptome of these ants becomes a useful tool, because it is possible to identify proteins potentially involved with their skills as insect pests and also those related to differences between the varieties present in the nests. In the present study we described results of the partial analysis of the transcriptome of the leaf-cutting ant pest A. laevigata, from cDNA sequences previously generated in the Laboratory of Evolution and Molecular (LEM). The results may also be used for molecular, ecological, metabolic and evolutionary studies about ants, and heterologous expression of important proteins as molecular targets for the control of some leafcutting agricultural pests.

Influência do Luar nas Atividades de Emergência e Retorno ao Abrigo do Morcego Hematófago Desmodus rotundus (Chiroptera, Phyllostomidae) no Sudeste do Brasil: subtitulo

The common vampire bat Desmodus rotundus has as main food source blood of medium and large sizes mammals, but sporadically is observed feeding on birds, causing occasionally excessive bleeding and economic losses. Due to this D. rotundus is one of the most studied species of bats in the Americas. Once known that the lunar clarity might influence the nocturnal activities of the common vampire bats, the present study was carried out to know the behavior and schedules of emergencies and returns of bats to the shelter, its social behavior at the shelter´s entrance, especially of the dominant male, and the size and composition of the colony in different moon phases. The colony was composed by 105 individuals (65 females and 40 males) harboring in a hollow-tree of Farm Edgardia in Botucatu Municipality, State of São Paulo. Through the eight filming sessions, two for each moon phase, it was possible to observe that the distribution of emergences and returns to the shelter thought the night followed a specific pattern for each moon phase. The greatest number of emerging bats occurred in periods in which the moon was not born yet and the largest number of returns just before moon has been reached its maximum level in the sky. Therefore, the time period that bats are staying outside the shelter seems to be directly influenced by lunar light. This factor can influence the social activity of the colony and, in particular, the dominant male, who remains still on tree’s trunk, near the entrance of the shelter with greater frequency during periods of low moon light
