O presente estudo teve por objetivo verificar se a implementação das ações afirmativas que interferem favoravelmente no processo de aprendizagem e na construção da identidade das crianças e jovens da comunidade Quilombola Onze Negras, podem ser entendidas como instrumento de Inovação Pedagógica. Para isso, inicialmente, embasamos teoricamente este estudo através da compreensão do conceito de ações afirmativas, e realizamos um resgate histórico das lutas empreendidas pelos negros no Brasil, tendo por foco a formação das comunidades quilombolas e a identidade dos negros brasileiros. Na sequência, as incursões à comunidade em estudo, a observação das suas vivências e a realização de inquéritos e entrevistas, dentro e fora da escola, permitiram-nos permear as nossas reflexões acerca deste contexto. Assim, a base metodológica utilizada nesta investigação foi a etnopesquisa crítica de natureza descritivo-exploratória e de abordagem qualitativa, cujos instrumentos utilizados foram a observação participante, a entrevista semi estruturada e o questionário. Os dados recolhidos possibilitaram-nos descrever, interpretar, compreender e analisar as ações cotidianas de nossos atores em seu ambiente natural, e, deste modo, concluir que as ações afirmativas realizadas no seu interior e mais especificamente na escola da comunidade Onze Negras, proporcionando um fortalecimento da identidade negra, podem ser vistas como instrumento de inovação pedagógica.

With more or less 213.000 habitants, Mossoró is the second more developed city from the Rio Grande do Norte. The town is proclamated like the land of freedom. To so far, exist four moments in your history related with the defence of freedom that is point like truthful from so proclamation. Suchlike happenings are the first female vote on Brazil, the resistance against the Lampião s band, the worman s mutiny and the slave release in 1883, five year before the Áurea law sanction. These happenings are commemorate yearly on setember with one big theatrical event called by the freedom high. Inside this contexto of exaltation to freedom, there is one black movement by name black and beautiful. Is the present dissertation, talked about the building of black identities between the black militants of Mossoró and the dwellers from the Santo Antônio district. With such approach, we intend to think about possibles differences or likeness, how the militants and dwellers from the refered district self-calleds like blacks or not. We are understanding black identity like one process to self-affirmation done by specificities of the social context and the individual particularity. This way, the identity change into one dynamic and contextual reality, gone always by one business process against the interaction of the social actors. So we search to discuss the specificities that involve the process to building of black identities in the city of freedom

With the purpose to study the emergence of Cenchrus echinatus L. and Cosmos sulphureus Cav. in response to time and depth of sowing, two experiments were conducted in uncontrolled environmental conditions in the months of June and September 2009. Cenchrus echinatus L. and Cosmos sulphureus Cav seeds were sown at different depths (0, 1, 3, 5, 7 and 9 cm). The experiments were conducted in pots, with five replications of 50 seeds per pot, followed by evaluation of the emergence percentage and emergence speed index (ESI). The highest percentage of emergency and higher EVR were observed up to 5 cm depth and the species Cosmos sulphureus Cav. was more sensitive to temperature variations due to the time of sowing of the species C. equinatus.

Visando estudar a tolerância do picão-preto (Bidens pilosa) a diferentes níveis de pH do substrato, conduziu-se um ensaio em condições de câmara de crescimento e utilizando-se a técnica de hidroponia, no qual três plântulas foram transplantadas para recipientes contendo solução nutritiva de Hoagland & Arnon, com pH ajustado para 3,5, 4,0, 5,0, 6,0, 7,0 e 8,0. O delineamento experimental utilizado foi o inteiramente casualizado com três repetições. Ao final do período experimental, 42 dias após o transplante, observou-se que as plantas que se desenvolveram nos pHs 3,5 e 8,0 apresentaram-se menores, com menor comprimento e volume do sistema radicular, menor número de folhas vivas e, consequentemente, menor peso de matéria seca das folhas, caule e raízes. Os teores de N e S nas raízes diminuiram com o aumento do pH do substrato, enquanto os de Ca e Mg aumentaram e os de K e P diminuiram no pH 5,0 a 6,0. No caule, apenas o teor de Mg foi afetado pelo pH, mostrando resposta positiva. Na folha obteve-se os maiores teores de P, S, Ca e Mg quando a planta se desenvolveu em pH 6,0. Não se constatou diferença significativa entre os efeitos dos pHs 5,0, 6,0 e 7,0 nos parâmetros avaliados, sendo que foi no pH 6,0 que se estimou, através de análise de regressão, melhor desenvolvimento do picão-preto. Concluiu-se que o picãopreto apresenta melhor desenvolvimento em pHs próximo ao neutro, com certa tolerância a pHs extremos (3,5 e 8,0).

This work aims at understanding of social suffering, caused by unsolved homicides in the black population. Thus, when the homicide occurs, family and friends become hidden or indirect victims of this crime. So, It will be made a historical imbalance of Afro-Brazilians to the capitalist system after slavery. Those who suffered from the absence of inclusive public policies. Also try to contextualize them within the current data with that place as the immediate victims of murder. Finally, reports from family members, through their life stories, and snippets from the ethnographic field notes were the methodologies used

Este trabalho foi conduzido com o objetivo de avaliar o desempenho de matrizes pesadas, submetidas a diferentes programas de alimentação estabelecidos pela aplicação de modelos para predizer as exigências energéticas, após o pico de postura. O experimento foi conduzido no setor de avicultura da UNESP Campus Jaboticabal, com duração de 84 dias (três períodos de 28 dias). Foram utilizadas 740 matrizes de corte Hubbard Hy-Yield e 80 machos Petterson, com 55 semanas de idade. O delineamento foi inteiramente casualizado, com quatro tratamentos e cinco repetições de 37 aves por repetição (box) e um modelo fatorial 4´3 (quatro tratamentos ´ três períodos). Os programas de alimentação avaliados foram: T1 - Fornecimento de ração de acordo com o padrão da linhagem (428 kcal/ave/dia de 55 a 66 semanas de idade); T2 - Redução semanal de energia (2 kcal de EM/ave em cada semana); T3 - Fornecimento de ração de acordo com o modelo de exigência de EM, UNESP (2000); e T4 - Fornecimento de ração de acordo com o modelo, NRC (1994). O programa de alimentação com redução semanal de energia foi adequado para manter os desempenhos produtivo e reprodutivo das aves, indicando a possibilidade de redução de 2 kcal/ave/dia, em cada semana, na alimentação de matrizes pesadas após 55 semanas de idade. Os modelos UNESP e NRC proporcionaram estimativas mais elevadas das exigências energéticas que o modelo padrão, provavelmente em decorrência do ganho de peso das matrizes, que esteve acima do recomendado para a linhagem, promovendo maiores exigências de energia para mantença.

The objective of this work was to evaluate conditions the effectiveness of acetolactate synthase (ALS) and protoporphyrinogen oxidase (PROTOX) inhibitors in the Bidens pilosa control under two water deficit conditions, as well as to determine the influence of water deficit under the contents of soluble carbohydrates and protein of weed. The experimental design was randomized completely design with the treatments, with four replications, setup in a factorial scheme 4x2, with four herbicides (fomesafen lactofen, chlorimuron-ethyl and imazethapyr), and two water conditions (-0.5 MPa and -0.01MPa). At 7, 14, 21 and 28 days after application (DAA), was assessed visually control efficiency of herbicides. For the determination of organic solutes plants were collected at 24, 48, 72 and 96 hours after application (HAA). Herbicides controlled efficiently plants of B. pilosa, except lactofen, whereas the water deficit affected the efficiency of control of all the herbicides. The soluble carbohydrate content increased with the imposition of water deficit, however, herbicides and water deficit further reduction of soluble proteins in plants of B. pilosa.

Considering articles written for Fernando Pessoa in 1912 about The new Portuguese poetry , where he already proclaimed the appearance of the Super-Camões, poet that would be able to revolutionize Portuguese literature e, concomitantly, to make resurging from rubble the Portuguese nation; we understand that, decades before the writing of Message, the poet was already armed with a Will of Power , expression of Friedrich Nietzsche that incorporate the idea of resurgence to the man like creator of news values. Fernando Pessoa believed to make his poetical word, the epic, restoring word of the ideas of Messianism and Fifth Empire as the pushing force of the new Portuguese largeness. However, we look for to investigate the conditions of Malaise that surround the universe of the poem and that restrict its capacity of action on the reality in its return, a time that the space destined in modernity to the poet and to his poetry hindered him of a devoted and positive action, We select therefore theorist like Sigmund Freud e Walter Benjamin
Samba e negritude: práticas discursivas identitárias negras em sambas de enredo de temática africana
Resumo:
The study object of this thesis is the process of affirmation, (re)construction and (re)signification of the black identities in the discourses which cross the samba-enredo of African theme of the samba schools belonging to the elite group from the carioca carnival, in the period from 1960 and 2007. The main question which guides this research is the following: How does this discursive process occur and which are the possible effects resulting from it? This research aims to understand, through interpretation gestures of such discourses and from those which undergo the interview statements and the answers given to the questionnaires applied to spectators and parade exhibiters of these samba schools, in what way the negritude conception and the citizenship practice of the black Brazilian people, especially those from Rio de Janeiro, can be affected by the meaning production circulating in the discursive practices of these sambas. The research was theoretically related to the Applied Linguistics, however it articulates theories originated from Cultural Studies and Ethnic-racial Studies as well as it presents some theoretical and methodological fundamentals from the Discourse Analysis of French line. As concerns the methodology, it is of interpretative, qualitative basis with procedures of discursive character. The interview analysis did not reveal, as consequence of the discourses circulating in the sambas, a direct involvement of the black people who were interviewed in struggle for their citizenship practice, but it pointed out sliding of meaning in regard to the negritude emergence
