Profissão: repórter esportivo - das narrativas da nação ao ofício do jornalista contemporâneo

Essa dissertação tem por objetivo investigar de que maneira o repórter esportivo contemporâneo se relaciona com o futebol e como essa relação interfere no seu ofício e na construção do texto jornalístico. Mais especificamente, busca identificar as práticas adotadas e as estratégias narrativas utilizadas na construção de seus textos. O estudo dos elementos presentes na prática jornalística tem como perspectiva que a mídia participou ativamente da construção do imaginário futebolístico nacional e é na contemporaneidade a grande mediadora entre o público e os eventos esportivos. É sob este prisma que se pretende apurar como se dá a relação com o trabalho do profissional de imprensa que se identifica com seu objeto, analisar qual o lugar da emoção na composição da notícia esportiva e verificar que valores imbuem esse profissional na construção do texto jornalístico. A análise tem como corpus entrevistas de história oral temática com seis jornalistas que atuam ou atuaram como repórteres esportivos em jornais diários da cidade do Rio de Janeiro, todos com expressiva trajetória no meio esportivo, o que lhes confere credibilidade e autoridade públicas para protagonizar a constituição da memória da imprensa esportiva brasileira. O trabalho é constituído por três etapas: 1) a contextualização – quando se relaciona futebol e formação social brasileira, imprensa e jornalismo esportivo -; 2) o estudo do jornalismo como ofício a partir das teorias da Sociologia das Profissões e das estratégias narrativas utilizadas no texto noticioso esportivo nos jornais; e 3) a análise qualitativa das entrevistas temáticas.

Forecasting daily volatility using high frequency financial data

Aiming at empirical findings, this work focuses on applying the HEAVY model for daily volatility with financial data from the Brazilian market. Quite similar to GARCH, this model seeks to harness high frequency data in order to achieve its objectives. Four variations of it were then implemented and their fit compared to GARCH equivalents, using metrics present in the literature. Results suggest that, in such a market, HEAVY does seem to specify daily volatility better, but not necessarily produces better predictions for it, what is, normally, the ultimate goal. The dataset used in this work consists of intraday trades of U.S. Dollar and Ibovespa future contracts from BM&FBovespa.

Tradução, adaptação cultural e análise das propriedades psicométricas do activities of daily living questionnaire - ADLQ - para avaliação funcional de pacientes com a doença de alzheimer

O Activities daily living questionnaire - ADLQ foi elaborado para avaliar atividades básicas e instrumentais em pacientes com a doença de Alzheimer. O objetivo principal deste estudo consistiu em realizar a tradução do ADLQ para a língua portuguesa, adaptação transcultural e análise das suas propriedades psicométricas. A amostra foi composta por 60 pacientes e os respectivos 60 cuidadores. O estudo iniciou-se com a tradução do instrumento pela técnica de retrotradução associada ao método bilíngüe. A versão traduzida foi respondida pelo cuidador e o Mini Exame do Estado Mental (MEEM) aplicado ao paciente. A análise psicométrica foi realizada através da validade das medidas do instrumento. Os resultados verificaram uma correlação inversamente significativa (r=-0,793;p<0,05) entre os instrumentos avaliados, com uma explicação da variância total de 62%. A coerência interna do instrumento foi realizada através da correlação com os resultados do MEEM sugerindo uma versão condensada do ADLQ. Avaliando-se através do teste t para amostras correlacionadas, as médias do ADLQ-versão traduzida e versão condensada não apresentaram diferenças significativas, demonstrado assim que a simplificação do instrumento não alterou os valores do nível de dependência funcional observados. A análise fatorial realizada através da rotação Varimax indicou seis dimensões. Atividades como; comer, vestir-se, banho, necessidades fisiológicas, tomar comprimidos, participação em grupos, administrar finanças, manusear dinheiro, locomover pela vizinhança, usar telefone, compreensão, dentre outras, são os mais importantes preditores da capacidade funcional, no grupo estudado. Atividades com desempenho pouco comum a ambos os sexos, e no desempenho de papéis sociais enquanto gênero na sociedade brasileira (afazeres domésticos, consertos e manutenção em casa), na amostra estudada, não demonstraram ter importância na determinação da capacidade funcional com o paciente com a Doença de Alzheimer. O presente estudo disponibiliza uma nova ferramenta de avaliação funcional, visando contribuir para a mensuração mais cuidadosa do estado funcional do paciente por todos os profissionais da área da saúde

Folha de São Paulo: o diário oficial do grande irmão

This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Experimental airborne transmission of Salmonella Agona and Salmonella Typhimurium in weaned pigs

This study tested the hypothesis of airborne transmission of Salmonella Agona (Trial I) and Salmonella Typhimurium (Trial II) in weaned pigs. The trials were performed using stainless-steel/glass isolation cabinets connected by air ducts to permit an unidirectional airflow from cabinet 1 (two control pigs) to cabinet 3 (two sentinel pigs), passing through cabinet 2 (two inoculated pigs). Air samples, pooled faecal samples from the floor and rectal swabs were collected daily and assessed by culture and PCR. A fumigation chamber and rubber gloves coupled to the cabinets allowed sampling without opening the system. Trials I and II lasted 15 and 19 days respectively. The recovery of S. Agona and S. Typhimurium and detection of scroconversion in sentinel pigs indicate that airborne Salmonella transmission in weaned pigs over short distances is possible. Further studies on the role of aerosols in the epidemiology of Salmonella in intensive pig production should be performed.

Prediction of intake and average daily gain by different feeding systems for goats

A main purpose of a mathematical nutrition model (a.k.a., feeding systems) is to provide a mathematical approach for determining the amount and composition of the diet necessary for a certain level of animal productive performance. Therefore, feeding systems should be able to predict voluntary feed intake and to partition nutrients into different productive functions and performances. In the last decades, several feeding systems for goats have been developed. The objective of this paper is to compare and evaluate the main goat feeding systems (AFRC, CSIRO, NRC, and SRNS), using data of individual growing goat kids from seven studies conducted in Brazil. The feeding systems were evaluated by regressing the residuals (observed minus predicted) on the predicted values centered on their means. The comparisons showed that these systems differ in their approach for estimating dry matter intake (DMI) and energy requirements for growing goats. The AFRC system was the most accurate for predicting DMI (mean bias = 91 g/d, P < 0.001; linear bias 0.874). The average ADG accounted for a large part of the bias in the prediction of DMI by CSIRO, NRC, and, mainly, AFRC systems. The CSIRO model gave the most accurate predictions of ADG when observed DMI was used as input in the models (mean bias 12 g/d, P < 0.001; linear bias -0.229). while the AFRC was the most accurate when predicted DMI was used (mean bias 8g/d. P > 0.1; linear bias -0.347). (C) 2011 Elsevier B.V. All rights reserved.

Longitudinal study of daily variation of rats' behavior in the elevated plus-maze

We conducted a longitudinal study about daily variation of Wistar male rats' behavior in the elevated plus-maze (EPM) evaluated in the 1st, 2nd, 3rd, 6th, 12th, and 18th months of life. Animals were submitted to the plus-maze in 12 sessions at 2-h intervals (n=72, 6 per time point). Spontaneous rest-activity rhythm of four animals was assessed by observation of 24-h videotape records. Time series were analyzed by Cosinor method. Behavioral rates on the six occasions and in light and dark phases were compared by means of two-way ANOVA with repeated measures. Exploratory behavior in EPM was smaller in the light phase and in older animals. Higher values of open and closed arms exploration were observed in the first and third months of the dark phase, and in the first month of the light phase. Adjustment to the 24-h period was significant at all stages for rest-activity data, number of entries in closed arms, and time on center, and for three to five stages for open-arm exploration. In general, 24 h variability was more pronounced in younger animals compared with older ones. The present study showed that: (1) a significant amount of total variability of the behavioral indexes analyzed could be attributed to 24 h variation, (2) light/dark phases differences in EPM exploration were present at all developmental stages, (3) older Wistar rats explored less the EPM and were less active in their home cage compared with younger ones, and (4) behavioral indexes (EPM) decrease was phase related and partially related to a reorganization of rest-activity rhythm.

Opiniões de professores do ensino médio: refletindo sobre os projetos escolares e a interdisciplinaridade

Official documents indicate to a curriculum organization that promotes the dialogue in different areas of knowledge. Among the proposals strategies are the "School Projects". This research appears from the staff need evidenced in the development of practice of the researcher in recent years as Pedagogical Advisor in high school. The comments made in the daily work on the kinds of projects and how they were developed in the school, generated concerns. They aroused the interest in further the discussion, aiming to reflect with teachers about the implementation of a pedagogic action on the use of educational projects in the classroom, as a didactic strategy which promotes the learning of students. In this sense, it seeks to develop studies and discussions by the application of questionnaires and the holding of a workshop with teachers in the area of Science of Nature and Mathematics in private high school institutions from Natal, searching opinions of them as the preparation and development of school projects. As general purpose, it aims to contribute with elements to the reflection of the teachers on the use of this strategy of education. For both, we propose: the knowledge of ideas/opinions of teachers on planning, development and evaluation of projects, both disciplinary and interdisciplinary, identifying the main difficulties of these teachers about the work with projects at school; reviewing projects developed at school after the press conference in a meeting with teachers, incorporating the identified aspects as weak points. In the course of the methodology research, questionnaires were used with open and closed questions for the lifting of preliminary ideas for teachers in order to subsidize the planning of a developed meeting later in the school itself on the subject in question. 10 teachers took part of the first step and 17 in the second one (pressconference). In the third stage, an individual interview was carried out and analysis of projects already developed. It is observed that, as the main difficulty for the development of projects in school, pointed to the time factor in the planning team, followed by excessive working hours for teachers that, generally, also work in other schools. Some teachers say they do not develop projects for not having knowledge of how to develop school projects, neither disciplinary, nor interdisciplinary

Dexamethasone-induced insulin resistance is associated with increased connexin 36 mRNA and protein expression in pancreatic rat islets

Augmented glucose-stimulated insulin secretion (GSIS) is an adaptive mechanism exhibited by pancreatic islets from insulin-resistant animal models. Gap junction proteins have been proposed to contribute to islet function. As such, we investigated the expression of connexin 36 (Cx36), connexin 43 (Cx43), and the glucose transporter Glut2 at mRNA and protein levels in pancreatic islets of dexamethasone (DEX)-induced insulin-resistant rats. Study rats received daily injections of DEX (1 mg/kg body mass, i.p.) for 5 days, whereas control rats (CTL) received saline solution. DEX rats exhibited peripheral insulin resistance, as indicated by the significant postabsorptive insulin levels and by the constant rate for glucose disappearance (K-ITT). GSIS was significantly higher in DEX islets (1.8-fold in 16.7 mmol/L glucose vs. CTL, p < 0.05). A significant increase of 2.25-fold in islet area was observed in DEX vs. CTL islets (p < 0.05). Cx36 mRNA expression was significantly augmented, Cx43 diminished, and Glut2 mRNA was unaltered in islets of DEX vs. CTL (p < 0.05). Cx36 protein expression was 1.6-fold higher than that of CTL islets (p < 0.05). Glut2 protein expression was unaltered and Cx43 was not detected at the protein level. We conclude that DEX-induced insulin resistance is accompanied by increased GSIS and this may be associated with increase of Cx36 protein expression.
