Que contribuições são suficientes para a constituição da autoria no ambiente acadêmico? Como saber se merecemos a condição de coautores ou se devemos figurar apenas na seção de agradecimentos de um trabalho publicado? Como devemos proceder para evitar, ao máximo, conflitos de autoria em pesquisas acadêmicas? Como autores e editores devem encaminhar disputas de autoria já instaladas? A partir dessas questões, observamos, por meio de pesquisa bibliográfica interdisciplinar, que muitas áreas de estudo vêm alertando para os efeitos deletérios do produtivismo acadêmico sobre a atribuição de autoria; o qual, ora inflaciona os créditos de alguns pesquisadores, ora usurpa os de outros. Nos últimos ciclos avaliativos da pós-graduação brasileira, a área do Direito tem adotado instrumentos de avaliação que enfatizam a pontuação relativa aos trabalhos publicados, ...

O arcabouco teorico foi construido a partir dos conceitos de formacao continuada, de Novoa, do professor reflexivo de Zeichner e dos conhecimentos profissionais para ensino com tecnologia, segundo Mishra e Koehler. A metodologia e a qualitativa do tipo Design-Based Research. Os dados foram coletados a partir de observacoes, dos protocolos das tarefas e filmagens em audio/video sendo este ultimo analisado segundo o modelo analitico de Powell, Francisco e Maher. Os resultados evidenciaram a emergencia de reflexoes sobre docencia com o uso da tecnologia, sobre planejamento e preparacao de tarefas, alem de mobilizacao do conhecimento pedagogico, tecnologico e matematico.

This information will assist in quality care strategies in the teaching and learning process. The characteristics of deafness are also presented as the cognitive development of these students, as well as analysis of the inclusion and integration process and its distinctions. It also reports the use of the bilingual method, which considers LIBRAS (Brazilian Sign Language) as the natural language of the deaf (L1) and the Portuguese language as the second (L2). It also presents the rights provided by law for a quality service that ensures the presence of the interpreter, in the classroom, and the recognition of LIBRAS as the natural language of the deaf. It is notepoint that the use of the term "hearing impaired" in this study, is due to the knowledge that some documents and laws use therapeutic clinical terms to refer to deafness as "disability" in society. The information needed for the analysis was obtained through qualitative research and bibliographic references, which are:

This paper reports the cytotoxic and genotoxic analyses of oleoresins and leaves extracts of Copaifera species: C. duckei, C. multijuga, C. paupera, C. pubiflora, C. reticulata and C. trapezifolia. In vitro assays were performed using Chinese hamster lung fibroblasts (V79 cells). The clonogenic efficiency and cytokinesis-block micronucleus assays were employed for the cytotoxicity and genotoxicity assessment, respectively. The mouse bone marrow micronucleus test was used for in vivo studies. The UPLC-MS/MS and CG/MS analyses of Copaifera oleoresins allowed the identification of the 10 acid diterpenes and 11 major volatile sesquiterpenes. Leaves are rich in phenolic compounds including 2 flavonoid heterosides and 16 galloylquinic acid derivatives. The cytotoxicity results obtained by the clonogenic efficiency assay showed IC values ranged from 9.8 to 99.2µg/mL to oleoresins and...

These compounds are known for their hepatoprotective, anti-inflammatory, antimicrobial, hypoglycemic, antimutagenic, antioxidant, and antifertility activities. In the present study, we evaluated the effects of UA and OA on the formation of 1,2-dimethyl-hydrazine (DMH)–induced aberrant crypt foci (ACF) in the colon of the male Wistar rat. The animals received subcutaneous (sc) injections of DMH (40 mg/kg body weight) twice a week for two weeks to induce ACF. UA, OA and a mixture of UA and OA were administered to the rats five times a week for four weeks by gavage at doses of 25 mg/kg body weight/day each, during and after DMH treatment. All animals were sacrificed in week 5 for the evaluation of ACF. The results showed a significant reduction in the frequency of ACF in the group treated with the t...
