The aim of this research was to investigate how the gender representations by young people affect how they interpret and resolve a situation of moral conflict at school. It starts from the references of the Theory of the Organizing Models of Thinking and of critical perspectives on the studies of gender as contributors of conceptual and methodological aspects in the analysis of the psychic functioning. Information was raised with 400 youngsters (15 to 21 years of age) from public and private schools, who answered in writing four questions about feelings, thoughts, and the duty of the characters (boys or girls) before a situation of homophobia at school. The perspective of the gender in the conflict resolution was analyzed taking into account the sex of the characters and the sex of the participants. The results show that the gender representations have an essential role in the manner in which the youngsters resolve interpersonal conflicts, highlighting the reproduction of stereotypes in the social relations among genders at school.

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.

A pesquisa analisa o novo marco regulatório da comunicação da Argentina, a Lei n° 26.522/2009 de Serviços de Comunicação e Audiovisual (LSCA). O texto é referência reguladora emblemática e contemporânea para os campos de estudos da Comunicação, das Políticas Públicas e da Economia Política da Comunicação na América Latina. O caráter original dessa legislação reside na aproximação de uma concepção inovadora do direito à comunicação e na atribuição de um novo papel regulador reservado ao Estado. A criação de uma nova arquitetura institucional para o desenho das políticas de comunicação, o estabelecimento de limites de propriedade para empresas e grupos da radiodifusão e a divisão do espectro radioelétrico em partes iguais para operadores privados, estatais e privados sem fins de lucro são objetos de especial atenção. Nesse sentido, são analisadas as premissas normativas da LSCA e os obstáculos à sua implantação. O processo de elaboração e implantação dessa nova legislação é inseparável do momento político e da correlação de forças políticas do país e de um fenômeno comum na América Latina desde a redemocratização: a emergência da sociedade civil e a luta pela difusão dos direitos de cidadania. A pesquisa aponta tensões entre politicas públicas progressistas e velhos costumes impregnados no Estado, como o fortalecimento de grupos de mídia próximos ao governo de turno e o uso oficialista dos canais de comunicação estatais. Assim, a LSCA revela baixo grau de materialização, a despeito de representar um avanço normativo, institucional e político chave para o país e a região na perspectiva da democratização da comunicação

The main goal of this bachelor work is the study of the physical properties of solids by thermal expansion coefficient measurements, which allows the exploration of various aspects of phase transitions. In this study, some theoretical aspects were focused, for example the first and second order phase transitions, Landau theory for phase transition and the volumetric thermal expansion coefficient. Furthermore, on the origin of the thermal expansion from the Lennard-Jones potential, that contains the anharmonic terms, which give rise to the phononic thermal expansion in solids

A simple and fast method to determine Ca, K and Mg in a single aliquot of medicinal plants by HR-CS FAAS is proposed. The secondary lines for Ca (239.856 nm) and K (404.414 nm), and the alternate line measured at wing of the secondary line for Mg at (202.588 nm) allowed calibration within the 20 - 500 mg.L-1 Ca and K, and 1.0 - 80 mg.L-1 Mg. Twenty samples and three plant certified materials were analyzed. Results were in agreement at a 95% confidence level with reference values. Limits of detection were 2.4 mg.L-1 Ca, 1.9 mg.L-1 K and 0.3 mg.L-1 Mg. The RSD (n=12) were ≤ 5.1% and recoveries were between 83 and 108% for all analytes.

This work describes instrumental strategies for the determination of Mn in a wide range concentration by high-resolution continuum source flame atomic absorption spectrometry technique (HR-CS F AAS) by means of different atomic lines (primary at 279.482 nm, secondary at 403.075 nm and alternative at 209.250 nm). These lines provided complementary concentration intervals, and large sample dilutions became unnecessary. The proposed method was applied to tap water, metal alloy certified material and foliar fertilizer. Accuracy for secondary line were evaluated by tests of significance (t Student test) with reference materials from the Institute of Technological Research of São Paulo, and the results were in agreement at the 95% confidence level. For primary and alternative lines, recovery is were in the 84-116% range and the RSD were 6.1% for all wavelengths. Analytical curves in the 0.1 - 2.0 mg L-1 (279.482 nm), 2.0 - 25 mg L-1 (403.075 nm), 25 - 500 mg L-1 (209.250 nm) intervals were obtained with linear correlation coefficient better than 0.9991. The detection limits were 3.3x10-3 mg L-1 (279.482 nm), 7.4 x 10-3 mg L-1 (403.075 nm), 3.9 mg L- 1 (209.250 nm). The found Mn concentrations were < 3.3x10-3 mg L-1 (tap water), 1.00 ± 0.04 (% m/m) (alloy IPT 25), 7235 ± 175 mg L-1 (foliar fertilizer 1), 4990 ± 132 mg L-1 (foliar fertilizer 2). A method was developed to detect interference of Fe in the Mn primary line (279.482 nm) using the ratio of absorbances of other lines of the triplet (279.827 nm and 280,108 nm).
