Educação Matemática e Sociedade

The paper's aim is to justify the creation of the line of research Mathematics Education and Society in the Graduate Program of Mathematics Education (PPGEM), UNESP (Rio Claro, SP). In a brief history of the constitution of the mathematics education community, the categories culture and society were emphasized. A brief summary of sociology is presented, drawing on classical sociologists and contemporary authors. The group EMsociedade is presented, and its purpose, which is to be part of the PPGEM to establish a space for discussions between students and supervisors from the Graduate Program, elementary and middle school teachers, and others who have interest in the subject. One of the arguments defended by the group is presented: institutionalized mathematical knowledge in the Twentieth Century is a commodity. Finally, some future considerations are outlined, including the expectation that the line of research Mathematics Education and Society will be included in the PPGEM.

Starting by the passage on the pathway of the internet, cyber culture and web journalism, and some concepts of news production, it is aimed to describe and evaluate, from the content of the proposed analyzes by Laurence Bardin, about general aspects, strategies and bulletin samples. Bringing a little of its history and description of the journalistic and news main points. The present paper approaches how these criteria, news value, and tools are chosen and used to reach the effectiveness of the proposal to take specific and fast information to the readers. Questions regarded to the opinionated character from the content were also stated as a way to evaluate its expressiveness

Formação da imagem do professor na Folha de S. Paulo durante a greve de 2010

The objective of this paper is to discuss the construction of the image of São Paulo state public schools teachers in the public sphere, by the media and the trade union press, and see how that image is formed in both of them, without making any comparisons, from the covering of 2010 strikes by newspapers Folha de S. Paulo and Jornal da Apeoesp. This paper uses as theoretical basis the study of Media Hegemony, the concept of Radical Media and Public Sphere, as well as the relationship between them and social movements. It also considers the observation of the history and characteristics of trade union press and the Standards of Manipulation by the Press, proposed by Perseu Abramo. The chosen method was the identification, selection and organization of stories about education published by Folha de S. Paulo during the period; the application of Abramo’s proposed manipulation standards on the stories about the strike; research, selection and observation of print publications (Jornal da Apeoesp and newsletters Apeoesp Urgente) about the strike, published by Apeoesp during the same period

Phenolic compounds, carotenoids, tocopherols and fatty acids present in oils extracted from palm fruits

This review aimed to discuss the main bioactive compounds present in oils extracted from palm trees, indicating possible applications for the same. The bioactive compounds approached were: phenolic compounds, carotenoids, tocopherols, mono and polyunsaturated fatty acids. It is growing the search for food, especially from plant origin, characterized by the presence of such substances due to their benefi ts. Many studies show palm species as important sources of bioactive compounds and essential fatty acids. Therefore it is important to study the fruit characterization and composition of the oil from palm species of different regions that are still poorly investigated, seeking the possibility of its application in industry or the development of functional foods.

A obra do poeta politradutor Armand Robin: marcas de uma existência em fuga

Armand Robin was a prodigious translator, that is to say: his works were translated into 22 different languages, not to mention his missing texts. During his bulletin on the radio, it was also possible to notice that 18 idioms were fluently received. This poet was notable not only because of his capacity of knowing several languages, but also because of his conception about translation. According to Robin, the meaning was not enough; a target text (TT) must be based on the recreation of the source text (ST), signification by signification; sound by sound, language by language. Since his first book, Ma Vie sans Moi, was released, Robin always wanted his translated texts were presented as works of his own, creating the idea that there was no difference between ST and TT, before giving priority to translation, either in publications or in radio transmissions. In 1942, ÉditionsGallimard published his single “novel”, Le temps qu’ilfait, which was object of studies related to the poet as a translator, emphasizing the pulse of life, which was visible in his TTs. However, in our paper, we are going to observe his production as an author, more specifically his writings, his novel and some of his fragments, in order to deepen the knowledge about his experience and also understand the dramatic and peculiar speech which is present in his writings.

Enzimas de biotransformação em tilápia (Oreochromis niloticus) exposta ao hormônio natural 17b-estradiol

Among the sexual hormones the estrogens are receiving major attention due to their biological activity. Such biological response is atributed to the best conformation recognized by their receptors, resulting in maximum responses. The estrogens are also considered responsible for most of disruptor´s effects caused by their presence in aquatic ecosystems. The 17β-estradiol hormone is produced by vertebrates during the reproductive phase of their lives and its presence has been detected in superficial waters. The objective of this study was to evaluate the cause-effect of tilapia exposition to the hormone 17β-estradiol through the analysis of biotransformation enzymes in liver and gills, complemented with the quantification of 17β-estradiol and estrone in water samples collected from fish ponds integrated to swine production. The present study was conducted under laboratory conditions, in a randomized experimental design with three levels of 17β-estradiol (E2) (0, 5, 15 µg L-1), with three replicates. After 7 days of exposure time, liver and gills were extracted to analyze three isoforms of cytochrome P450: EROD, BROD, PROD and the activity of Glutathione S-Transferase (GST). The results showed that the EROD activity (CYP1A), normally induced by the metabolism of aromatic compounds, did not present statistical differences among the treatments exposed to E2, what means that the hormone did not induce isoform 1A in fish under these particular experimental conditions. PROD activity was significantly altered in both concentrations, by means of 5 and 15 µg L-1, when compared to control. This result can indicate an important role of PROD on the metabolism of E2 present in water. Regarding to the BROD activity, it could be observed differences statistically significant between control and both groups of treatments. Two or more CYP isoforms can contribute to the metabolism of the same compound, what makes BROD a candidate as a next bioindicator of the exposure to E2 in aquatic ecosystems. Analysis of variance could confirm the effect of E2 statistically significant on the GST activity in liver tissues with >90% of significance (Prob>F = 0.0753). Furthermore, it was possible to observe that the values of GSTs activities in liver and gills in both, control and treatments, follow a tendency, that means, enzymatic activity in gills increase as the increasing of the activity in the liver tissues. In this study, the 17β–estradiol was found in measurable concentrations in three sampled points, and these values were similar to the findings of other authors at different locations in Brazil. In addition, those values are much higher than the minimum concentration that presented observable effects (10 ng L-1).

Abordagem Leader: uma aproximação com o programa territórios da cidadania

Analyzing evidences of the LEADER approach in the Territories of Citizenship Program consists in the immediate objective of this paper. Considering the current context in which the territorial approach takes on the challenge of promoting a less excluding development, the deepening of discussions and experiences highlighted in national and international scope can add elements for analysis and creation of proposals for a more efficient development. Methodologically, a qualitative analysis of bibliographic data and interviews involving focal subject types was performed. In the analysis performed it was possible to understand that the policy of territorial approach is necessary, but it has structural implications that hinder the work of those who should mediate and sensitize the most excluded social groups. Therefore, so that there is an effective policy it would be necessary to create participatory and emancipatory models able to produce structural changes.

Escola Pacheco e Silva anexada ao Hospital de Juqueri (1929-1940)

This article presents the results of research on the Hall-School installed in the Juqueri Hospital, São Paulo, in 1929, by initiative of the psychiatrist Antonio Carlos Pacheco e Silva, and organized by the pediatrician Vicente Baptista da Silva and professors Norberto de Souza Pinto and Celso Guimarães da Fonseca. It is regarded as a real pioneer project for the development of Special Education and of Psychology, formerly named as for the abnormals. One can neatly perceive the change in the treatment of a medical origin only to that of an inclusion of Psychology and Education in the development of children affected by mental deficiency or by psychopathies. The influence of the ideas of educators, such as the ones mentioned above, were fundamental for the changes.
