O objetivo da presente pesquisa, de caráter descritivo, foi comparar o desempenho na produção de textos de alunos de escolas pública e particular, que freqüentam as 5as. e 8as. séries do Ensino Fundamental.

O texto discute a presença, em textos conversacionais, de diferentes modalidades de estruturas frasais (frases verbais, nominais, truncadas, e frases com sujeito elíptico). Também é discutido o papel das citadas modalidades na estruturação do texto conversacional.

Em textos conversacionais, o turno de fala é o espaço preferencial da manutenção da referência: os elementos anafóricos e os respectivos antecedentes figuram geralmente no mesmo turno. Por isso, a progressão temática, nessa modalidade de textos, ocorre em termos bastante genéricos; cada falante retoma o assunto da conversação, mas a ele acrescenta o próprio ponto de vista. Também se discute o fato de que as contribuições de cada falante não são aleatórias, mas seguem o princípio de cooperação de Grice e o conhecimento prévio partilhado pelos participantes do ato conversacional.

The purpose of this article is twofold. First, it examines how Discourses, socially accepted ways of speaking, listening, writing, and reading that illustrate individuals' memberships in specific social groups (Gee, 2008), could influence teachers' use or censorship of polemic text in the classroom. Second, this article presents a review of the research literature about teachers' inclusion of culturally diverse themes in their classrooms. For example, it describes professors' use of children´s books about racism with new teachers. It also outlines suggestions for guiding discussions that respect students' heritage, build critical literacy, and support culturally responsive teaching pedagogies.

Objectives: To investigate the adhesive potential of novel zirconia primers and universal adhesives to surface-treated zirconia substrates.Methods: Zirconia bars were manufactured (3.0 mm x 3.0 mm x 9.0 mm) and treated as follows: no treatment (C); air abrasion with 35 mu m alumina particles (S); air abrasion with 30 mu m silica particles using one of two systems (Rocatec or SilJet) and; glazing (G). Groups C and S were subsequentially treated with one of the following primers or adhesives: ZP (Z-Prime Plus), AZ (AZ Primer); MP (Monobond Plus); SU (ScotchBond Universal) and; EA (an Experimental Adhesive). Groups Rocatec and SilJet were silanized prior to cementation. Samples form group G were further etched and silanized. Bars were cemented (Multilink) onto bars of a silicate-based ceramic (3.0 mm x 3.0 mm x 9.0 mm) at 90 degrees angle, thermocycled (2.500 cycles, 5-55 degrees C, 30 s dwell time), and tested in tensile strength test. Failure analysis was performed on fractured specimens to measure the bonding area and crack origin.Results: Specimens from group C did not survive thermocycling, while CMP, CSU and CEA groups survived thermocycling but rendered low values of bond strength. All primers presented a better bond performance after air abrasion with Al2O3 particles. SilJet was similar to Rocatec, both presenting the best bond strength results, along with SMP, SSU and CEA. G promoted intermediate bond strength values. Failure mode was predominately adhesive on zirconia surface combined to cohesive of the luting agent.Conclusions: Universal adhesives (MP, SU, EA) may be a considerable alternative for bonding to zirconia, but air abrasion is still previously required. Air abrasion with silica particles followed by silane application also presented high bond strength values. (C) 2013 Elsevier Ltd. All rights reserved.
