O jogo das identidades como fator de mobilização político-eleitoral nas campanhas de Dilma Rousseff e Rosalba Ciarlini em 2010

Starting from the premise that we live in the society of spectacle, as proclaimed by Guy Debbord, and, in this context, the media feeds itself off of this spectacularization and constructs a culture of images and production of goods, providing templates from which the subject can identify himself/herself as being male or female, successful or unsuccessful, powerful or powerless. In other words, the culture conveyed by the media produces material for the creation of identities through which individuals insert and recognize themselves in contemporary society. Observing the election campaigns, we can see clearly that this profusion of identities is fairly explored in the advertising propaganda used by the candidates, particularly in the propaganda broadcasted on the Free Electoral Time on TV. Instigated by the explicit relation between the media and politics within the society of the spectacle, this study aims to investigate the main identities that emerge in the discursive practices of the media in the election campaigns of 2010 for president of the Republic and governor of the State of Rio Grande do Norte that had as protagonists the candidates at that moment Dilma Rousseff (PT) for president and Rosalba Ciarline (DEM) for governor. To do so, we based ourselves on the theory of Bakhtin Circle, which considers the statement as a unit of verbal communication and conceives language as a dialogical phenomena and a discursive practice and also in the conceptions of dialogical relationships, social voices and chronotope formulated by the previous mentioned theory. Still in the theoretical field, we have established an interconnection with the theories coming from the Cultural Studies (Hall, Woodward) about the identity, which conceives it as multiple, fragmented, non-fixed, so that, the subject assumes different identities, not always coherent, at different times, depending on the context in which they are approached. The research is situated in the frames of Applied Linguistics, which considers language as the center of its studies and settles on the border of an open number of areas of knowledge expanding its possibilities of investigation by means of the interdisciplinary. Our corpus consists in 20 electoral propaganda videos aired on TV during the Free Election Time in 2010 campaign; among these, 14 videos are Dilma Rousseff s propaganda and 06 videos are Rosalba Ciarline s propaganda. We seek for the purpose of the analysis to identify the identities which emerge from the discourses about the candidates in propaganda videos broadcasted in the referred campaign, as well as realize the dialogical relations established in these discourses and even if the identity construction of these subjects is located in the same axiological axis. The corpus analysis revealed that the multiple cultural identities of the candidates campaigning emerge in the discourses circulating in the electoral propaganda aired on TV such as: the identities of pioneer woman, competent, sensitive, mother, grandmother, religious. And, yet, those are changeable as the electoral demands, in other words, the need to obtain support and votes, outline a fluid identity construction about the candidate to the position in question

Consumo e digestibilidade aparente de dietas com níveis crescentes do subproduto do caju em ovinos

The present study was conducted to evaluate the intake and digestibility of diets containing increasing levels of byproduct of cashew in sheep. The animals were distributed in a completely randomized design were evaluated in four levels (0%, 20%, 40%, 60%) by product of cashew with four replicates, making up 16 observations. The indicator used was the Purified Lignin and Enriched - LIPE ®. The scorer was orally administered directly into the mouth of the animals, in the form of capsules 250mg/animal/dia for a period of two days and five days of adaptation samples being the same supplied with the aid of a hose polyethylene and a device allowing the release of the capsule in the esophagus of sheep. With the estimate made by the indicator LIPE was observed a reduction for DM, OM, CP, NDF, EE, NFC and MM along the inclusion of byproduct of cashew. The results of nutrient digestibility were not satisfactory with the inclusion of byproduct of cashew, reducing linearly with the inclusion of the diets. The use of increasing levels of byproduct of cashew in the diets of sheep did not provide satisfactory results, it is not feasible to use the animals studied in this experiment

Ecologia alimentar do boto cinza, sotalia guianensis (van banédén, 1864), no litoral do rio grande do norte (rn)

This study investigated factors that influence the group size during the behavior foraging of estuarine dolphin Sotalia guianensis in the coast south of the state Rio Grande do Norte (RN), it also characterized the diet of estuarine dolphins and elaborated an otoliths catalog for aid in the identification of the preys found in the stomach contents. In relation to the group size during behaviour foraging, inside of the Curral Bay, larger frequency of solitary hunt was observed. Factors as tide variation, group composition and seasons didn't present correlation with the number of animals observed during a feeding episode. Capture success for participant was shown significantly larger when the animals hunted alone, what possibly explains the largest frequency of solitary hunt inside of the Curral Bay. About diet, were identified 18 bone fishes species, with predominance of species the families Haemulidae and Sciaenidae and five cephalopods species, including two new species in the diet of Sotalia guianensis in Brazil. Our results indicated that estuarine dolphin in the coast oriental from Rio Grande do Norte (RN) feeds predominantly of fish that form shoal, of habitat estuarino and producing of sounds. The analysis of the images, otoliths of 43 species of coastal fish of the coast of the state of Rio Grande do Norte (RN), aided by the offered descriptions, demonstrated to be an effective methodology for the knowledge of those structures, as well as it represented a form of reducing the subjectivity in the identification of the bone fishes found in stomach content

Boto cinza (Sotalia guianensis, Van Benédén, 1864) (Cetacea, Delphinidae): Atividade aérea, forrageio e interações inter-específicas, na Praia de Pipa (Tibau do Sul RN) e estudo comparativo entre duas populações do Nordeste do Brasil

Sotalia guianensis is a small cetacean of the Delphinidae family, with coastal habits and whose area of distribution ranges from Florianópolis (27º35'S, 48º34'W), in Brazil, to Honduras (15º58'N, 85º42'W). At Pipa beach, on the south coast of RN state, in Brazil, the species occur throughout the year. The present study was carried out in two bays, which are bordered by cliffs. The animals were monitored from vantage points, using the "Ad libitum" and "all the occurrences" methods; during the years of 1999 and 2004. The study was divided in 4 chapters: Behavioral standards of two populations of gray dolphin, (Sotalia guianensis, Van Benédén, 1864) in the northeast of Brazil; Aerial activity of the gray dolphin: its possible function and the influence of environmental and behavioral factors; The influence of daily and monthly variation of the tides, of the period of the day and group size on the gray dolphin forage activity; kleptoparasitism interactions of frigatebird (Fregata magnificens, Mattheus, 1914) during the gray dolphin forage activity. The results have shown that the gray dolphin has a varied and complex behavioral repertoire. The leap is the most frequent behavior; the aerial activity is diffuse during daylight and is influenced by some factors, such as the level of the tide and social factors. The gray dolphin, when in the bay, most frequently feeds isolate or in small groups. The forage is diffuse during daylight; however, being more frequent in the morning and is influenced by the daily and monthly variation of the tide. At Pipa beach, kleptoparasitarian interactions were registered between the gray dolphin and the frigatebird (Fregata magnificens). The frigatebird forage strategy consists basically of two ways: to fly over great extensions searching for dead fish and to steal food (kleptoparasitism). These interactions were predominantly carried out between immature and female adult birds and adult and immature dolphins, and occurred during daylight. The present study can be considered an initial landmark to a better knowledge on the gray dolphin surface behavior, especially regarding the aerial behavioral repertoire and forage strategy of this species. However, it is necessary to continue these studies, so that we can understand better the complex social life of these animals and thus create effective measures for its conservation

Circuit board accident - organizational dimension hidden by prescribed safety

This study analyzes an accident in which two maintenance workers suffered severe burns while replacing a circuit breaker panel in a steel mill, following model of analysis and prevention of accidents (MAPA) developed with the objective of enlarging the perimeter of interventions and contributing to deconstruction of blame attribution practices. The study was based on materials produced by a health service team in an in-depth analysis of the accident. The analysis shows that decisions related to system modernization were taken without considering their implications in maintenance scheduling and creating conflicts of priorities and of interests between production and safety; and also reveals that the lack of a systemic perspective in safety management was its principal failure. To explain the accident as merely non-fulfillment of idealized formal safety rules feeds practices of blame attribution supported by alibi norms and inhibits possible prevention. In contrast, accident analyses undertaken in worker health surveillance services show potential to reveal origins of these events incubated in the history of the system ignored in practices guided by the traditional paradigm.

Determination of selenium by GFAAS in slurries of fish feces to estimate the bioavailability of this micronutrient in feed used in pisciculture

This paper presents a simple, fast and sensitive method to determine selenium in samples of feces and of fish feed by graphite furnace atomic absorption spectrometry (GFAAS) through the direct introduction of slurries of the samples into the spectrometer's graphite tube. The limits of detection (LOD) and quantification (LOQ calculated for 20 readings of the blank of the standard slurries (0.50% m/v of feces or feed devoid of selenium) were 0.31 mu g 1(-1) and 1.03 mu g 1(-1), respectively, for the standard feces slurries and 0.35 mu g 1(-1) and 1.16 mu g 1(-1), respectively, for the standard feed slurries. The proposed method was applied in studies of bioavailability of selenium in different fish feeds and the results proved consistent with that obtained from samples mineralized by acid digestion using the microwave oven.

Determination of chromium by GFAAS in slurries of fish feces to estimate the apparent digestibility of nutrients in feed used in pisciculture

This paper presents a simple, fast and sensitive method to determine chromic oxide (used as a biological marker of fish feed) in samples of fish feces by GFAAS through the direct introduction of slurries of the samples into the spectrometer's graphite tube. The standard samples of feces and of fish feed containing 0.10-1.00 mg kg(-1) of Cr2O3 were pre-frozen for I min in liquid nitrogen and then ground a cryogenic mill for 2 min, which reduced the samples' grain size to less than 60 mu m. The standard slurries were prepared by mixing 20 mg of standard samples of fish feed or feces with I mL of a solution containing 0.05% (v/v) of Triton X-100 and 0.50% (v/v) of suprapure HNO3 directly in the spectrometer's automatic sampling glass. The final concentrations of Cr2O3 present in the standard slurries were 2, 4, 8, 16 and 20 mu g L-1. After sonicating the mixture for 20s, 10 mu L of standard slurries were injected into the graphite tube, whose internal wall was lined with a metallic palladium film that acted as a permanent chemical modifier. The limits of detection (LOD) and quantification (LOQ) calculated for 20 readings of the blank of the standard slurries (2%, m/v of feces or feed devoid of minerals) were 0.81 and 2.70 mu g L-1 of Cr2O3 for the standard feces slurries, 0.84 and 2.83 mu g L-1 of Cr2O3 for the standard feed slurries. The proposed method was applied in studies of nutrient digestibility of different fish feeds and its results proved compatible with the results obtained from samples pre-mineralized by acid digestion.

Disponibilidade aparente do fósforo em alimentos vegetais e suplementação da enzima fitase para tilápia-do-nilo

Este estudo foi realizado com o objetivo de avaliar o efeito da fitase (0, 1.000 e 2.000 uf/kg) na disponibilidade aparente de P de cinco alimentos energéticos (milho, milho extrusado, farelo de trigo, farelo de arroz e sorgo baixo tanino) e cinco alimentos protéicos (soja extrusada, farelo de soja, farelo de girassol, farelo de algodão e glúten de milho) utilizando-se uma ração purificada como controle. Foram utilizados 100 juvenis (100,00 ± 5,00 g) de tilápia-do-nilo (Oreochromis niloticus) alojados em dez gaiolas para manejo de alimentação e coleta de fezes. Para cada alimento e cada nível de fitase avaliado, foram coletadas amostras em cinco gaiolas, totalizando cinco repetições por tratamento. Os resultados obtidos indicaram que a suplementação de até 2.000 uf/kg de fitase não aumentou a disponibilidade aparente de P do farelo de trigo e do farelo de algodão. Entretanto, o nível de 1.000 uf/kg aumentou a disponibilidade aparente de P da soja extrusada e do farelo de girassol, enquanto o nível de 2.000 uf/kg proporcionou essa resposta para o farelo de milho, o milho extrusado, o sorgo baixo tanino, o farelo de arroz, o farelo de soja e o glúten de milho.

Coeficientes de digestibilidade e valores de aminoácidos digestíveis de alguns ingredientes para tilápia do Nilo (Oreochromis niloticus)

O objetivo deste estudo foi determinar o coeficiente de digestibilidade aparente (CDA) dos aminoácidos do milho, farelo de trigo, farelo de soja e da farinha de peixe. Empregaram-se juvenis de tilápia do Nilo (Oreochromis niloticus) (25,24 ± 3,88 g) alimentados com ração referência peletizada contendo 0,10% de óxido de crômio (indicador) e 33,78% de proteína bruta. O CDA médio dos aminoácidos foi de: 88,31; 77,40; 91,78 e 82,58% para o milho, farelo de trigo, farelo de soja e farinha de peixe, respectivamente. Ainda que os resultados sugiram que o CDA da proteína possa ser indicativo do CDA dos aminoácidos, seus valores individuais variaram dentre e entre os ingredientes avaliados. Os resultados obtidos demonstram que os valores de aminoácidos digestíveis devem ser usados na formulação de rações completas (precisas) e econômicas.

Effect of nucleotides on broiler performance and carcass yield

This study aimed at evaluating the effect of nucleotides on the performance and carcass yield of broilers fed diets with no antibiotic growth promoters (AGP), anticoccidials, or animal feedstuffs. In the trial, 600 Ross 308 male broilers were distributed in a completely randomized experimental design into six treatments with four replicates of 25 birds each. Treatments consisted of a control diet (CD), CD + AGP, CD + 0.04%, CD + 0.05%, CD + 0.06%, and CD + 0.07% nucleotides. The experimental diets did not contain anticoccidials, and birds were vaccinated against coccidiosis at three days of age. No significant differences were detected among broilers submitted to the different treatments in none of the studied parameters. Under the conditions of this experiment, diets supplemented with nucleotides did not influence broiler performance or carcass yield at 42 days of age, and were not different from the feeds not containing any additive or with AGP.

Digestibilidade de alimentos protéicos e energéticos para fêmeas de beta

Foram avaliados os coeficientes de digestibilidade aparente de MS, PB, energia bruta (EB) e EE de alimentos protéicos (farelo de soja e farinha de peixe) e energéticos (fubá de milho e farelo de trigo) para beta (Betta splendens). Fêmeas adultas foram alojadas em gaiolas e mantidas em dois aquários de fibra de vidro (30 peixes/aquário) para alimentação e dois para coleta de fezes, ambos de formato cônico e com capacidade para 30 L. Os resultados dos coeficientes de digestibilidade aparente de MS, PB, EB e EE foram, respectivamente, de 69,43; 72,52; 67,91 e 55,50% para farelo de soja; 60,67; 51,15; 75,55 e 58,26% para farinha de peixe; 63,88; 87,16; 77,61 e 50,40% para fubá de milho; e 61,06; 93,37; 58,17 e 65,51% para farelo de trigo. Os resultados obtidos neste estudo permitem otimizar a formulação de dietas práticas balanceadas, economicamente viáveis para a espécie.

Desempenho de bezerros holandeses alimentados após o desaleitamento com silagem de grãos úmidos ou grãos secos de milho ou sorgo

Avaliou-se o desempenho de bezerros alimentados após desaleitamento e até o abate com silagem de grãos úmidos ou grãos secos de milho ou sorgo para a produção de vitelos de carne rosa. Trinta bezerros holandeses foram distribuídos em delineamento em blocos casualizados, com cinco blocos e seis tratamentos, e alimentados com seis rações concentradas com teores similares de proteína (18,5% PB) e energia (3,2 Mcal EM/kg de MS), formuladas com: milho seco moído (MM); silagem de grãos úmidos de milho (SGUM); sorgo seco com tanino moído, (SCTM); silagem de grãos úmidos inteiros de sorgo com tanino (SGUISCT); sorgo seco sem tanino moído (SSTM); e silagem de grãos úmidos inteiros de sorgo sem tanino (SGUISST). Os animais foram recriados em piquetes coletivos até atingirem o peso pré-estabelecido para o abate (170 ± 10 kg PC). Não houve efeito das rações concentradas sobre a altura de cernelha, a idade ao abate, os dias no experimento e os ganhos de peso diários e totais. Os custos por kg de ganho de peso das rações contendo sorgo foram mais baixos que o das rações formuladas com milho. Todos os alimentos avaliados podem ser usados em rações concentradas para bezerros após o aleitamento, pois não comprometem o desempenho e conferem resultados similares.

Composição físico-química de carcaças de bezerros holandeses alimentados após o desaleitamento com silagem de grãos úmidos ou grãos secos de milho ou sorgo

Avaliou-se a composição físico-química de carcaças de bezerros após desaleitamento até o abate com silagem de grãos úmidos ou grãos secos de milho ou sorgo para a produção de vitelos de carne rosa. Trinta bezerros holandeses foram distribuídos em delineamento em blocos casualizados, com cinco blocos e seis tratamentos, e alimentados com seis rações com teores similares de proteína (18,5% PB) e de energia (3,2 Mcal EM/kg de MS), formuladas com: milho seco moído (MM); silagem de grãos úmidos de milho (SGUM); sorgo seco com tanino moído (SCTM); silagem de grãos úmidos inteiros de sorgo com tanino (SGUISCT); sorgo seco sem tanino moído; e silagem de grãos úmidos inteiros de sorgo sem tanino (SGUISST). Após o resfriamento, foram tomados nas meias-carcaças esquerdas os cortes da seção H&H para estimativa da composição tecidual da carcaça e os cortes no Longissimus dorsi à altura da 12ª e 13ª costelas para determinação da área de olho-de-lombo (AOL), da espessura de gordura subcutânea (EGS), da força de cisalhamento (FC) e da composição química. Não houve efeito da composição das rações concentradas sobre a composição física e a relação entre tecidos na seção H&H, bem como para AOL, EGS e FC. A ração concentrada SGUM resultou em maiores teores de EE no Longissimus dorsi, mas não diferiu das rações SCTM e SSTM. A ração concentrada SGUM gerou maior deposição de gordura muscular em comparação à MM, no entanto, as rações SGUISCT e SGUISST não aumentaram essa deposição em comparação ao fornecimento dos grãos secos moídos. Todos os alimentos avaliados podem ser usados em rações concentradas para bezerros após o aleitamento, pois não comprometem a composições física e química da carcaça e conferem resultados similares.
