The oxidized cassava starch is widely used in various industrial sectors, the major textile, paper and more recently by the food industry due to its characteristics, such as expansion property to baking. This study aimed to develop a modification of cassava starch by reaction with hydrogen peroxide and lactic acid, with two different types of drying, in the sun and in oven dried, in order to develop the expansion with increase of carboxyl groups and to evaluate differences between the types of drying and compare them with Expandex® starch and pre-gelatinized. The results indicated an increase in the rate of expansion of the modified starch dry in the sun, however the results of the content carboxylic groups haven't indicated the relationship with their rate expansion.

Assuming that testimony in photojournalism must be understood as a historical and performative act, the aim of this article is to discuss how the testimonial function of journalistic photography was constantly re-signified in Brazilian news magazines during the twentieth century. This redefinition has a relation with the different ways in which testimonial function was hinged to news report (in its broadest elements) and how this imperative appeared on its discursive form in writing narrative. As trustee of a narrative intended to be realistic, photojournalism articulates, from techniques and codes of narration, a series of referential and informational strategies. These strategies, however, have changed over time, based on different modes of narration by image and its accreditation in reality.

Este estudo discute os efeitos dos comportamentos verbais vocais do terapeuta, em específico, orientação, interpretação e empatia, sobre os comportamentos do cliente de resistência e cooperação. Examina-se diferentes sistemas de categorização de comportamentos do terapeuta e cliente e como tais sistematizações permitem o estudo da interação terapêutica na terapia analítico-comportamental. São apresentadas diferentes pesquisas sobre as categorias orientação, empatia e interpretação, bem como as divergências e convergências de conclusões com relação aos efeitos positivos e negativos sobre os resultados da terapia. Constata-se que resultados discordantes sejam produzidos a partir de diferenças quanto aos procedimentos de coleta e análise dos dados utilizados. Por fim, discute-se que o impacto de categorias de comportamentos do terapeuta esteja condicionado à etapa do processo terapêutico e comportamentos precedentes do cliente e do terapeuta.

This text is the result of a larger study into the role of the mother tongue in the construction of school knowledge, with a view to promoting gains in the performance of teenagers. The three objectives in this particular paper are: (1) to address Feuerstein's ideas, how the mother tongue interrelates with specific content, and the management of pedagogical interaction; (2) to illustrate enriched interaction during interventions by the researcher; and (3) to point out that supervised internship actions may help underachieving students. This is done in light of an interpretive analysis of the specialized literature, course books, reports and notes concerning interventions with students, and video and audio recordings. The analysis of interactions and student output following the researcher's interventions reveals increased awareness and change regarding school knowledge and how speaking/writing about specific content may enhance their performance in the completion of pedagogical tasks.

La popularización de los medios digitales y los recursos de comunicación difunde las narrativas no lineales y agrava la crisis de la enseñanza en el aula, con la expansión de diferentes modelos presenciales virtuales de la educación (PVE). Es evidente la demasificación de los nuevos medios, en un contexto que agudiza la percepción individual y social de los individuos, que son atraídos por el enorme flujo global de mensajes informativos (BRIGGS; BURKE, 2006). La transición de los métodos de enseñanza en el aula para modelar la educación virtual e interactiva ganó un nuevo formato en la educación pública en São Paulo en 2012, con el lanzamiento de cursos electivos de enseñanza de Inglés y Español para estudiantes de la secundaria, con la mediación de el PC y con el contenido producido por la Escuela Virtual de Programas Educativos del Estado de São Paulo - Evesp. Aún continua presencia en los salones de las grandes clases del sistema escolar, la falta de materiales de enseñanza y aprendizaje adecuados en las clases impartidas por los profesores cuyos repertorios están alejados de la vida cotidiana de los estudiantes. En este contexto, se comprueban las actuaciones de aprendizaje cualitativos más bien negativos de las cuatro habilidades comunicativas: escuchar, hablar, leer y escribir (CAMERON, 2001). La investigación que llevamos a cabo es analizar las experiencias de enseñanza de Inglés y Español en la plataforma computarizada Evesp y de la clase de Inglés y Español de los Centros para el Curso de idiomas (CELS), para la escuela secundaria, y el piloto Early Bird, de enseñanza y el aprendizaje de Inglés de la escuela primaria, todos bajo la Junta de Educación de Bauru (SP).

Given the objective of the Educational Observatory Program of putting in conjunction the efforts of graduation and basic school in order to improve the quality of the latter, are sought possibilities offered by such an arrangement for teacher education. The assumed action research methodology is designed as a collective rethinking about the social practice in which participants were immersed. It is identified strong correlation among the school/graduation interaction and the nature of the underlying teacher education design. The constitution of research questions accomplished inside the school and the centrality of Small Research Groups in a broad network of interactions were determinants.
