A morenidade da china tropical: o racianalismo de Casa-grande e Senzala

This essay discusses the race issue, emphasizing the racial concept in Casa-Grande & Senzala. We discussed the Brazilian intellectual scene of the 1920s and 1930s, also the decadence of the analysis based on the variables of race, geographical environment and climate, emphasizing the ascent of new approaches, structured cultural diversity in the capitalist economy and exclusionary. We use the concept of racialism, understanding it as any narrative that classifies the types of people in a racial criterion

Tão longe, tão perto: pretos e pardos e o enigma racial brasileiro

Até meados da década de 1970 buscou-se decifrar o lugar social ocupado pelo pardo na sociedade brasileira. Contudo, os estudos mais recentes se caracterizaram, com algumas exceções, pelo silenciamento em torno das especificidades desse grupo. Pretos e pardos têm sido agrupados em uma mesma categoria para fins de análise de desigualdades e discriminação racial. No entanto, se os pardos estão extremamente próximos dos pretos no que toca os seus índices socioeconômicos, chances de mobilidade social e vitimização pela discriminação, eles estão muito distantes dos pretos em sua percepção do preconceito e da discriminação de que são vítimas. Para esse grupo, o nexo entre a cor e a discriminação não parece nem um pouco evidente. A presente tese retoma os pardos como tema de reflexão e investiga as razões pelas quais eles parecem ser discriminados em intensidade próxima à dos pretos, mas não reportam a discriminação no mesmo grau. A partir da produção de análises originais de dados quantitativos e surveys sobre racismo, encontro respaldo para algumas explicações não mutuamente excludentes para esse fenômeno: (1) o binarismo das linguagens racista e antirracista no Brasil, que exclui os pardos do debate público, (2) os problemas metodológicos dos surveys sobre discriminação racial, (3) a presença ideário da morenidade na identidade e autoimagem dos brasileiros pardos, (4) as peculiaridades da sociabilidade entre pretos, pardos e brancos, (5) o caráter ambivalente dos estereótipos que incidem sobre os pardos e, finalmente, (6) uma porosidade maior das elites brancas em relação a esses indivíduos. A partir da elaboração de um modelo alternativo de mensuração da percepção da discriminação, baseado na Escala de Discriminação Cotidiana, demonstro que pretos e pardos de classes mais baixas têm percepções mais parecidas de atitudes discriminatórias, enquanto aqueles que atingem as classes médias e elites passam a divergir: os pretos passam a reportar mais intensamente a discriminação, enquanto os pardos praticamente cessam de senti-la. Sustento que o racismo ambivalente brasileiro funciona de modo a barrar a mobilidade social tanto de pretos como de pardos, mas que os estereótipos e atitudes a que ele está relacionado penalizam mais severamente os pretos que ascendem socialmente do que os pardos.

Arcabouço jurídico normativo pedagógico da lei federal 10.639/2003 na universidade federal de Uberlândia: avanços e limites

This search addresses the public policies that directly or indirectly corroborate for the implementation of the Brazilian Law number 10.639/2003 in Federal University of Uberlândia and it analyzes the affirmative actions in this context. The study aims to answer some questions such as: Why we have found difficulties in implementing the Law 10.639/2003 and its correlate legislation in the institutions responsible for teachers formation, particularly in the courses of History, Visual Arts, Portuguese Language and Literature and Education teachers? We started from the hypothesis that implementing the Law 10.639/2003 is considered by popular movements that fight for the emancipation of black population and for its rights consider such actions as a form of eradicating racial and ethnic prejudice which are still present in our society. The methodology is based on case study, which allows the triangulation to other methodological approaches such as qualitative analysis and bibliographic search. The investigation instruments were: I. Bibliographic sources including books, papers, periodic and so one; II. Documental sources: specific legislation on the theme (Brazilian Federal Law 10.639/2003, Resolution CNE/CP 1/2004 and others; III. Oral sources obtained from semi structured interviews with coordinators of the selected Graduation courses. Critical multicuturalism according to McLaren (1999) allowed us to approach our research object in order to understand its plural characteristics, specially reading the different aspects that permeate the relationship between culture and identity, cultural differences and power relationship in modern society. In the study, we did not perceive the involvement of the Higher Education professionals in order to implement Law 10.639/2003. The problem perceived for implementing the law and its pedagogical normative legal framework is the personal and institutional attitude, because every subject involved in it has a direct responsibility. We cannot believe that the institutions may claim lack of knowledge and research in the area as impediments to implementing the disciplines and the pedagogical contents concerning to the Law nor contracting researcher experts and scholars on this topic to compose the frames of the University.

De uma chuva de manga ao funk de Lelê: imagens da afrodiáspora em uma escola de Acari

Nesta pesquisa o objetivo principal é discutir o padrão de beleza historicamente hegemónicos em uma escola Pública Muncipal de Educação Infantil, na periferia do Rio de Janeiro, em Acari. Tenho como pressuposto para pesquisa que neste tempoespaço escolar se estabelece uma tensão entre as invisibilidades e visibilidades de imagens de heróis e heroínas e suas narrativas africanas e afrobrasileiras em relação às identidades, pois nesse espaço escolar parte da representação do humano é preferencialmente eurocêntrico-branca, embora os indivíduos que frequentam àquele espaço - crianças e educadoras sejam em sua grande maioria negros e mestiços. É neste cotidiano escolar que desenvolvo uma pesquisa/intervenção, articulando brincadeiras e tecnologias com literatura infantil da contemporaneidade. Intervenção que propõe uma discussão em torno da ética e da estética. Tal abordagem me instiga a investigar e a discutir as questões de relação étnico-raciais dessa escola e as emergências de heróis e heroínas da afrodiáspora.

Relationship between plasma and red blood cell concentrations of quinine in Brazilian children with uncomplicated Plasmodium falciparummalaria on oral therapy

Neste estudo foi determinada a relação entre as concentrações plasmáticas e eritrocitárias de quinina em crianças com malária falciparum não complicada, oriundas de área endêmica da Região Amazônica. A quinina foi detrminada por cromatografia líquida de alta eficiência. No estado de equilíbrio, a relação foi 1,89 ± 1,25 variando de 1,05 a 2,34. Estes resultados demonstraram que a quinina não se concentra nos eritrócitos das crianças e caracterizaram a ausência de diferença racial nesta relação.

Length-weight relationship of small pelagic fish species of the southeast and South Brazilian Exclusive Economic Zone

The b values varied between 2.72 and 3.53. The samples for this study were collected during hydroacoustic surveys covering an area of 700 000 square km.

The relationship between L3 transfer and structural similarity across L3 development: raising across an experience in Brazilian Portuguese

The present study examines three competing models of morphosyntactic transfer in third language (L3) acquisition, examining the particular domain of the feature configuration of embedded T in L3 Brazilian Portuguese (BP) at the initial stages and then through development. The methodology alternates Spanish and English as the L1 and L2 to tease apart the source of transfer to L3 BP. Results from a scalar grammaticality acceptability task show unequivocal transfer of Spanish irrespective of Spanish’s status as an L1 or L2. The data thus support the Typological Primacy Model (Rothman 2010, 2011, 2013a, 2013b), which proposes that multilingual transfer is selected by factors related to comparative structural similarity. Given that Spanish transfer at the L3 initial stages creates the need for feature reconfiguration to converge on the target BP grammar, the second part of this chapter examines the developmental consequences of what the TPM models in cases of non-facilitative initial transfer, that is, the developmental path of feature reconfiguration of embedded T in L3 BP by English/Spanish bilinguals. Given what these data reveal, we address the role of regressive transfer as a correlate of L3 proficiency gains.

Supercritical fluid extracts from the Brazilian cherry (Eugenia uniflora L.): Relationship between the extracted compounds and the characteristic flavour intensity of the fruit

Supercritical carbon dioxide (SC-CO(2)) extractions of Brazilian cherry (Eugenia uniflora L.) were carried out under varied conditions of pressure and temperature, according to a central composite 2(2) experimental design, in order to produce flavour-rich extracts. The composition of the extracts was evaluated by gas chromatography coupled with mass spectrometry (GC/MS). The abundance of the extracted compounds was then related to sensory analysis results, assisted by principal component and factorial discriminant analysis (PCA and FDA, respectively). The identified sesquiterpenes and ketones were found to strongly contribute to the characteristic flavour of the Brazilian cherry. The extracts also contained a variety of other volatile compounds, and part of the fruit wax contained long-chain hydrocarbons that according to multivariate analysis, contributed to the yield of the extracts, but not the flavour. Volatile phenolic compounds, to which antioxidant properties are attributed, were also present in the extracts in high proportion, regardless of the extraction conditions. (C) 2010 Elsevier Ltd.

BIRD FORAGING IN ANACARDIUM PATCHES IN CENTRAL BRAZILIAN FIRE BREAKS: RELATIONSHIP BETWEEN FLOCK SIZE AND PATCH SIZE

Fire management ran increase the biomass of some plant species at fire breaks in reserves of the Cerrado. For example, numerous and large patches of monkey-nuts (Anacardium humile, Anacardiaceae) provide abundant food resources for wildlife in the lower strata of savanna woodlands managed by fire. The objective of this study was to examine the exploitation of A. humile patches by birds in managed savanna woodlands (fire breaks) at Emas National Park, southwest Brazil. The relationship between flock size and the size of Anacardium patches were also investigated. Fire breaks were sampled in September and October 2006, when fruits and flowers were abundant. Ara ararauna was often recorded exploiting resources of Anacardium patches. This species and other psittacids (Amazona aestiva, Alipiopsittaca xanthops, and Diopsittaca nobilis) consumed seeds usually on the ground around fruiting patches. Members of Aratinga aurea flocks and Ramphastos toco consumed pseudo-fruits. Larger flocks detected were those of A. aurea and A. ararauna. Groups of A. ararauna that exploited larger patches tended to be larger than flocks that exploited smaller patches. This study suggests that intra- and interspecific interactions and characteristics of Anacardium patches and of the surrounding vegetation are involved in the feeding ecology of birds in the lower stratum of managed woodlands. Fruiting Anacardium patches attract numerous frugivorous birds to fire breaks at Emas National Park. Further research is needed to a better understanding of the influence of fire management on birds in the Cerrado. Accepted 31 July 2009.

O movimento negro e a Secretaria Especial de Políticas de Promoção da Igualdade Racial: um estudo sobre a luta por sentidos sobre a igualdade racial no Brasil

Esta dissertação tem como objetivo compreender o relacionamento do Movimento Negro e Estado brasileiro no processo de criação da Secretaria Especial de Políticas de Promoção da Igualdade Racial (SEPPIR). Pretendemos jogar luz sobre a relação entre Movimento Negro e Estado na constante luta pelo sentido e significado da desigualdade racial. Será que a constituição de uma Secretaria, com status de Ministério de Estado, é capaz de promover mudanças na visão de desigualdade racial institucionalizada pelo Estado brasileiro? Nosso estudo busca entender como o conflito sobre o sentido da desigualdade racial é incorporado às Políticas Públicas. Utilizamos a categoria analítica Movimento Social para compreender o Movimento Negro, identificando alguns frames que orientam a sua ação. Evidenciamos que estes frames se relacionam na constituição do lugar (entendido como uma série de ligações, nas quais os sentidos das relações sociais são construídos, onde há disputas de poder sobre esses sentidos) da SEPPIR. A ação do Movimento Negro coloca em conflito os sentidos institucionalizados pelo Estado, que se utiliza da cooptação para desmobilizar o Movimento. Ao discutirmos a relação entre Movimento e Estado, relacionamos os frames identificados com a naturalização da desigualdade racial. Essa versão institucionalizada atribui principalmente ao nosso passado escravocrata a causa dessa desigualdade, não apontando para a compreensão do papel do racismo na manutenção dessa desigualdade. Sugerimos, assim, que a noção de justiça, reposicionada pelo reconhecimento, e a discussão de direitos humanos podem ser um caminho, não apenas para lutar contra esta naturalização, mas também para irmos além da cooptação.

Is what you say what you do? Analyzing and comparing the effect of buyer-supplier relationship in the Brazilian and Chinese supplier selection criteria

Choosing properly and efficiently a supplier has been challenging practitioners and academics since 1960’s. Since then, countless studies had been performed and relevant changes in the business scenario were considered such as global sourcing, quality-orientation, just-in-time practices. It is almost consensus that quality should be the selection driver, however, some polemical findings questioned this general agreement. Therefore, one of the objectives of the study was to identify the supplier selection criteria and bring this discussion back again. Moreover, Dickson (1966) suggested existing business relationship as selection criterion, then it was reviewed the importance of business relationship for the company and noted a set of potential negative effects that could rise from it. By considering these side effects of relationship, this research aimed to investigate how the relationship could influence the supplier selection and how its harmful effects could affect the selection process. The impact of this phenomenon was investigated cross-nationally. The research strategy adopted was a controlled experiment via vignette combined with discrete choice analysis. The data collections were performed in China and Brazil. By examining the results, it could be drawn five major findings. First, when purchasers were asked to declare their supplier selection priorities, quality was stated as the most important independently of country and relationship. This result was consistent with diverse studies since 60’s. However, when purchasers were exposed to a multi-criteria trade-off situation, their actual selection priorities deviate from what they had declared. In the actual decision-making without influence of buyer-supplier relationship, Brazilian purchasers focused on price and Chinese buyers prioritized delivery then price. This observation reinforced some controversial prior studies of Verma & Pullman (1998) and Hirakubo & Kublin (1998). Second, through the introduction of the buyer-supplier relationship (operationalized via relational capital) in the supplier selection process, this research extended the existing studies and found that Brazilian buyers still focused on price. The relationship became just another criterion for supplier selection such as quality and delivery. However, from the Chinese sample, the results suggested that quality was totally discarded and the decision was majorly made through price and relationship. The third finding suggested that relational capital could legitimate the quality and sustainability of the supplier and replaces these selection criteria and made the decisional task less complex. Additionally, with the relational capital, the decision-makings were associated to few biases such as availability cognition, commitment, confirmatory and perceived biases. By analyzing the purchasers’ behavior, relational capital inducted buyers of both countries to relax in their purchasing requirements (quality, delivery and sustainability) leading to potential negative effects. In the Brazilian sample, the phenomenon of willing to pay a higher price for a lower quality offer demonstrated to be a potential counterproductive and suboptimal decision. Finally, the last finding was associated to the cultural effect on the buyers’ decisions. From the outcome, it is possible to observe that if a purchaser’s cultural background is more relation-oriented, the more he will tend to use relational capital as a decision heuristic, thus, the purchaser will be more susceptible to the potential relationship’s side effects
