Do encontro das águas ao Atlântico negro: organização, difusão de frames e os limites do ativismo transnacional no movimento negro brasileiro

Meu objetivo nesta tese é compreender o processo de transnacionalização do movimento negro brasileiro e as suas consequências para a luta antirracista no Brasil. Em outras palavras, busco compreender como os negros brasileiros se articulam com os negros do mundo para cumprir seus objetivos. Uma vez que hoje a cultura negra global tem sido compreendida a partir da metáfora do “Atlântico Negro”, que representa um espaço de trocas transnacional que conecta todos os sujeitos da diáspora negra, assumo esta mesma metáfora como ponto de partida para minha reflexão. Entretanto, me interessa refletir sob um dos aspectos do Atlântico Negro, que é a sua dimensão organizacional. Se é pelo Atlântico Negro que hoje circulam um conjunto de conteúdos que são compartilhados pela comunidade negra mundial, tais como idéias e práticas que estão relacionadas a religião, a música, a literatura e as formas de organização, então podemos afirmar que a organização do movimento negro brasileiro se alimenta também destas múltiplas dimensões. Para desenvolver esta linha de argumentação, a tese utiliza o caso do movimento negro brasileiro para analisar o processo de difusão de um frame transnacional racialista que é apropriado pelo movimento negro como base para a elaboração de um diagnóstico, prognóstico e ressonância das ações de combate ao racismo no Brasil e para a definição das estruturas de mobilização e das estratégias de ação do movimento. Contudo, esta apropriação não ocorre sem problemas, pois este frame enfrenta outros frames locais, de caráter não-racialista, o que acarreta severas restrições ao ativismo transnacional na medida em que o próprio movimento negro se vê diante do dilema entre manter o alinhamento com o frame transnacional e aproveita as oportunidades políticas oferecidas pelo racialismo, ou relativiza este frame fazendo algumas concessões em suas propostas e na sua organização, a fim de se adaptar aos frames locais, negociando estas oportunidades a partir das restrições existentes. Para entender esta dinâmica, proponho a metáfora do “Encontro das Águas” amazonense, como um ponto de argumentação complementar ao Atlântico Negro, pois leva em conta os aspectos locais da luta antirracista que se apoiam na mestiçagem como identidade autônoma que não se dilui facilmente na identidade negra. Além de desenvolver estes pontos, a tese contribui para compreender melhor a dialética entre o global e local, bem como as tensões advindas dos frames em disputa.

Risky business: social media metrics and political risk analysis

A quantificação do risco país – e do risco político em particular – levanta várias dificuldades às empresas, instituições, e investidores. Como os indicadores econômicos são atualizados com muito menos freqüência do que o Facebook, compreender, e mais precisamente, medir – o que está ocorrendo no terreno em tempo real pode constituir um desafio para os analistas de risco político. No entanto, com a crescente disponibilidade de “big data” de ferramentas sociais como o Twitter, agora é o momento oportuno para examinar os tipos de métricas das ferramentas sociais que estão disponíveis e as limitações da sua aplicação para a análise de risco país, especialmente durante episódios de violência política. Utilizando o método qualitativo de pesquisa bibliográfica, este estudo identifica a paisagem atual de dados disponíveis a partir do Twitter, analisa os métodos atuais e potenciais de análise, e discute a sua possível aplicação no campo da análise de risco político. Depois de uma revisão completa do campo até hoje, e tendo em conta os avanços tecnológicos esperados a curto e médio prazo, este estudo conclui que, apesar de obstáculos como o custo de armazenamento de informação, as limitações da análise em tempo real, e o potencial para a manipulação de dados, os benefícios potenciais da aplicação de métricas de ferramentas sociais para o campo da análise de risco político, particularmente para os modelos qualitativos-estruturados e quantitativos, claramente superam os desafios.

Digestibility and performance of pacu (Piaractus mesopotamicus) juveniles - fed diets containing different protein, lipid and carbohydrate levels

Due to lack of information on the use of non-protein energy sources in diets for pacu (Piaractus mesopotamicus), a 2 x 2 x 3 factorial experiment was conducted to evaluate the performance and digestibility of 12 diets containing approximately two crude protein (CP; 220 and 250 g kg(-1)), two lipid (40 and 80 g kg(-1)) and three carbohydrate levels (410, 460 and 500 g kg(-1)). The pacu juveniles-fed diets containing 220 g kg(-1) CP did not respond (P > 0.05) to increased dietary lipid and carbohydrate levels, but the fish-fed diets containing 250 g kg(-1) CP showed a better feed conversion ratio. There were interactions in weight gain (WG), specific growth rate (SGR), crude protein intake (CPI) and feed conversion rate (FCR) dependent on dietary carbohydrate and lipid levels, showing positive effects of increasing carbohydrate levels only for fish-fed diets containing 80 g kg(-1) lipid level. However, when the diets contained 40 g kg(-1) lipid, the best energy productive value (EPV) results were obtained at 460 g kg(-1) carbohydrate. A higher usage of lipids (80 g kg(-1)) reduced CPI and was detrimental to protein [apparent digestibility coefficient (ADC)(CP)] and energy (ADC(GE)), but did not affect growth. The ADC(GE) improved proportionally as dietary carbohydrate levels increased (P < 0.05), increasing the concentration of digestible energy. In addition, the WG, CPI, ADC(GE) results showed best use of the energy from carbohydrates when dietary protein level was 250 g kg(-1) CP. The utilization of 250 g kg(-1) CP in feeds for juvenile pacu for optimal growth is suggested. Therefore, the optimum dietary lipid and carbohydrate levels depend on their combinations. It can be stated that pacu uses carbohydrates as effectively as lipids in the maximization of protein usage, as long as it is not lower than 250 g kg(-1) CP or approximately 230 g kg(-1) digestible protein.

The Beatles: ensaio sobre a ética do amor

The thesis intends to discuss the ethics by the way of love. So, it uses as a mention the musical work and the set of attitudes of the group that changed the way of thinking across the 20th Century mass-comm, entering a new way of thinking about the World: The Beatles. Analyzing the lyrics and the writing of the songs was searched the comprehension of he intrinsic love message at the Ethics it expresses. At the musical art of The Beatles political messages had been announced in a time that the World sought a Ethic way beyond the several declared war and the Cold War. Taking the Edgar Morin works as a base, O método 6, Ética (2005), it sought to understand the idea who permeates the human relations: the good, the possible, the necessary. Another works used as a cognitive base were Meus demônios (2003), Cultura de massas no Século XX: neurose (2005), Cultura de massas no Século XX (2006), The Beatles Anthology (2000) and Many years from now (2000). Holding the Ethics idea showed by Morin were established imaginary lines that perpass the behavior of the group known in the entire World understood till nowadays as tolerance, comprehension, peace, love and endurance messengers. The Beatles operate during the sixties a musical reborn, which allowed to the people the discussion and the reflexion about the World and the human being new behavior,endurance but acting with tolerance. Permeating the basic study, we find the Beatles way, the group origin, the fast walk till success, the spiritual choice, who guide their behavior and the end of the band. The music used as a masscomp instrument passes by the condition of a simple way of communicating. It deeply action feeds feelings, allows transcendence and is showed as target of human being transformation. The Ethics in music passes by the ideological barriers and becomes to comprehension with a clear synthony for the man, cause the polyphony and the new musical order establish the messages worldwide

A fé e a religiosidade na cova de Pedro Ribeirão do largo -Bahia

At this research we attempted to understand what feeds and supports the faith and popular religiosity at Pedro s Cave in Ribeirao do Largo, located in Bahia State. For this we studied the visitation ritual at Pedro s Cave on June 29th and tried to identify the importance of this ritual in the construction and reconstruction of believer s faith. Moreover, we endeavored to understand which factors led Pedro Afonso Nascimento, a cowhand whose lift was taken in a violent manner, to the roll of popular saints and how it was built around his tomb a sanctuary of constant visitation

Atenção ao usuário em um centro de referência HIV/Aids: perspectiva de profissionais e usuários

We study the health care focused on care in an intercessor and dialogical relationship with the User, which involves the construction of therapeutic projects essential to the quality of the treatment of the user in health services, and it is necessary individual and collective actions. It is intended to acknowledge and analyze the perception of social subjects, users and professionals on the treatment given to a user of a Specialized Outpatient Service (Serviço Ambulatorial Especializado SAE) in STD/HIV/AIDS state reference in Natal, RN. The study is structured in a transdisciplinary vision of science and knowledge, theoretical and methodological principles that give meaning to the expression of the institutional features of care and health care reconnecting them to the social context. As a research strategy we seek the expressions of 56 subjects of social research, which agreed to participate in the sample, from a symbolic map of the attention, coupled with the techniques of observation and semi-structured interview. For the analysis of the results, five categories of analysis were established: the meaning of the service, care perception, process of communication and interaction, treatment perception and organization and evaluation of the service. It is argued that the attention and care are developed in a technical health care assistance to the disease, focusing on attention based on treatment, on diagnostic and drug therapy of antiretroviral drugs, reflecting the traditional biomedical paradigm of attention to the disease. This is also the mode of organization of practical actions in daily SAE: the therapy proves to be fragmented in several specialties, vertical and feeds the same model, generating tension and overload for professionals; showing impersonal care focused on structured and informative technology, unrelated to an interactive dialogic. From the speech of the subjects, the SAE is understood as the place of confrontation with the disease, but also enables greater elaboration of the illness by meeting their peers. Living with HIV and AIDS is living with concern, apprehension and fear, but mainly with the stigma, prejudice and exclusion, which require that the disease is kept in secret. There is a movement of forces and power, expressed in the knowledge-power of those who dominate the technical and administrative capabilities, devices that concentrate the maintenance of the medicalization of care, rapid consultations and with little attention, making it difficult to interact with and listen to, combined with structural failures, organizational and inadequate management of the service. We conclude that there are dimensions that are not considered in the internal dynamics of the care service multiple forms, characterized by care conflicting models, marked by individual interventions related to the disease. The subject is not considered together with his speech as technical discourse is imposed and care production based on material technology is observed

Effect of crude protein levels and organic selenium supplementation in the diets fed during the breeding season on reproductive parameters of red-winged tinamous (Rhynchotus rufescens)

There is little information on the nutrition of red-winged tinamous (Rhynchotus rufescens) reared in captivity, and their nutritional requirements still need to be determined. This study aimed at determining dietary crude protein requirements and testing four organic selenium supplementation levels in the diet of red-winged tinamous during the breeding season. Birds were housed in a conventional broiler house divided in 16 boxes with one male and three females each. Iso-energy (2800kcal ME/kg) pelleted feeds, based on corn and soybean meal, were supplied in tube feeders. In the first experiment, treatments consisted of four different diets containing different crude protein (CP) contents (15, 18, 21, or 24%) and in the second experiment, the four diets contained equal protein level (22.5%) and four different organic selenium levels (0, 0.2, 0.4, or 0.8ppm). Data were analyzed by the least square method. The best egg weight and eggshell thickness were obtained with 22.5% dietary CP. Organic selenium did not influence the studied reproductive traits of red-winged tinamous (Rhynchotus rufescens) males or females.

Desenvolvimento de Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae) em cafeeiros

A cochonilha Planococcus citri (Risso, 1813) suga a seiva dos botões florais e frutos do cafeeiro, atacando as rosetas desde a floração até a colheita. Embora seja relatada há alguns anos na cafeicultura, são escassas as informações sobre o desenvolvimento dessa cochonilha em cafeeiros. Assim, o presente trabalho teve por objetivos avaliar alguns aspectos biológicos da fase ninfal de P. citri em plantas de café. Ovos dessa cochonilha foram retirados de uma criação em laboratório, isolados em placas de Petri contendo discos foliares de Coffea arabica L., das cultivares Acaiá Cerrado, Mundo Novo e Catuaí Vermelho e de C. canephora Pierre & Froenher, cultivar Apoatã. As placas foram mantidas em câmara climatizada a 25 ± 1ºC, 70 ± 10% de umidade relativa e 12h de fotofase. Constatou-se que a cultivar Catuaí Vermelho foi a que proporcionou maior duração do período ninfal das fêmeas, porém, não foram constatadas diferenças na mortalidade. Essa cochonilha se desenvolveu satisfatoriamente em todas as cultivares de café estudadas e os resultados não mostraram diferenças claras de susceptibilidade.

Da formação ludopiética à autopoiese do lazer: significados para a autoformação humanescente do profissional do lazer

The present study aimed to understand and interpret the connections between the training of graduate ludopoiética leisure and the process of autopoiesis of leisure. From the main objective, the following objectives had been formulated specific: a) To interpret more significant the ludopoiéticas experiences in the academic formation of graduandos of leisure; b) To analyze the experiences of the leisure most significant, disclosed for the group investigated, before, during and after the course; c) To describe and to interpret the process of autopoiese of the leisure and its respective meaning for the autoformação human being. The study it articulated the following metodológicas boardings: autobiogr á fica, etnogr á fica and fenomenológica. For the construction of the ludopoiéticas bridges between the academic formation proposal for the course of Leisure and Quality of Life of the CEFET-RN and the autoformação lived deeply human being as leisure for the participants of the study, we use as categories of analysis, five properties that had constituted the respective autopoiético system of the leisure. Thus, for our autopoiética reflectivity we adopt the following categories: autotelia; autoliberação; autoconectividade; autovalia and autofruição. The carried through research obtained to evidence given important of the ludopoié tica formation of these professionals of the leisure for its autoforma ç ã o human being and the autocriação of the proper leisure, that for recursividade feeds this autoformação in way permanently. Lived deeply properties of the ludopoiético system in the formation are searched with autonomy in the leisure. Thus, the learning of the autotelia, the autovalia, the autofruição and the autoconectividade lived deeply during the course of graduation in Leisure and Quality of Life is valued by the emotion of the joy and the love to the life, having become something desired by the citizens that had chosen the leisure as profession

Live and formulated diet evaluation through initial growth and survival of jundiá larvae, Rhamdia quelen

A larvicultura da maioria das espécies de peixes enfrenta o desafio da dependência do alimento vivo (AL) e da falta de dietas formuladas (DF) que atendam plenamente às necessidades das larvas. A baixa digestibilidade e a qualidade nutricional das DFs são alguns dos fatores que explicam o insucesso quando as larvas recebem apenas FD. Para avaliar o efeito da combinação da DF com o AL no crescimento e na sobrevivência de larvas de jundiá (Rhamdia quelen), comparando com o uso separado da DF ou do AL, larvas recém eclodidas (5,57 mm; 1,41 mg) foram estocadas inicialmente em 12 aquários de 10 L (100 larvas por aquário). Quatro réplicas foram alimentadas ad libitum com uma das três dietas por 20 (para DF) ou 48 dias (para AL ou a combinação DF + AL). As larvas alimentadas com apenas DF apresentaram crescimento e sobrevivência reduzidos quando comparadas àquelas alimentadas com AL ou a combinação DF + AL. Adicionalmente, as larvas do tratamento DF + AL apresentaram maior crescimento em peso (170 mg) que aquelas alimentadas apenas com AL (110 mg). O melhor desempenho das larvas alimentadas com DF + AL mostra que a maioria dos nutrientes exigidos pelas larvas é fornecida mais adequadamente quando ambas as dietas são fornecidas juntamente. Contudo, trabalhos sobre nutrição larval poderão contribuir ainda mais sobre a elucidação deste tema quando feitas comparações com o uso combinado de DF + AL, do que apenas testando isoladamente novos ingredientes e fontes protéicas normalmente utilizadas na elaboração de dietas para juvenis e adultos.

Evaluation of yeast cell wall on the performance of broiles fed diets with or without mycotoxins

This experiment aimed at evaluating the effects of the interactions between aflatoxin (500 or 250 ppb) and ochratoxin (500 or 250 ppb), and the possible benefits of adding yeast cell wall to prevent the effects of these mycotoxins in broiler chickens. Relative organ weight gain and live performance were evaluated at 21 and 42 days of age. Results indicated that at the levels of mycotoxins included in the experimental diets, ochratoxin reduced feed intake and body weight gain, and aflatoxin only affect feed intake of 21-day-old birds. No interaction was observed between aflatoxin and ochratoxin at the levels used in experimental study. Yeast cell wall did not significantly reduced the deleterious effects of ochratoxins. No significant differences were observed in relative organ weight gain. Yeast cell wall improved feed conversion ratio when birds were fed either contaminated or non-contaminated feeds.
