A ideologia politica no humor

Muitas pessoas têm o costume de atribuir às charges dos jornais apenas o papel de peça de entretenimento por utilizar o discurso lúdico. Mas suas características vão além de simples passatempos. Por se tratar sempre de criticar fatos reais, elas representam a opinião das empresas que as publicam. Isso fica ainda mais evidente em ano eleitoral. Em 2002, dois jornais da capital federal – Jornal de Brasília e Correio Braziliense – defenderam candidaturas diferentes quanto ao cargo de governador do Distrito Federal. As posições de cada um podem ser identificadas de acordo com os temas e personagens satirizados pelos veículos em suas charges. No Jornal de Brasília, os alvos das críticas representadas nas ilustrações foram o fato de haver um 2º turno na capital e denúncias de corrupção envolvendo o candidato Geraldo Magela, do PT. Ambos assuntos foram publicados com o objetivo de desestimular a campanha do petista, o que favorecia o seu principal adversário, Joaquim Roriz, do PMDB, atual e governador na época. Isso demonstra que as charges foram utilizadas como ferramentas do jornal para apoiar o peemedebista, logo se deduz ser essa a ideologia do veículo. Opondo ao posicionamento do Jornal de Brasília, as charges do Correio Braziliense apontavam suas críticas para denúncias de corrupção envolvendo Roriz. O que favorecia a campanha de Magela, pois a intenção dessa mídia era denegrir a imagem do governador para que esse perdesse as eleições. Como uma das características das charges é expor a linha editorial do veículo, torna-se imprescindível à comparação entre os temas ironizados no Correio e Jornal de Brasília, já que esses tomaram posições opostas. Sátiras que retratavam alvos diferentes revelavam ideologias distintas. Portanto, comparar estas representações facilita entender a ideologia de cada veículo

LONGITUDINAL ASSESSMENT OF YOUNG SWIMMERS’ PERFORMANCE AND ITS PREDICTORS

The purpose of this study was to develop a performance predictor model based on biomechanics. Ninety-one swimmers (44 boys and 47 girls) were evaluated. The decimal age, anthropometrics, kinematics and efficiency parameters were collected in ten different moments over three seasons. Hierarchical linear modeling was the procedure selected to estimate the performance predictors. The decimal age (Estimate: -2.05; P < 0.001), arm span (Estimate: -0.59; P < 0.001), stroke length (Estimate: 3.82; P = 0.002) and propelling efficiency (Estimate: -0.17; P = 0.001) entered the final model. The decimal age, arm span, stroke length and propelling efficiency were the main predictors. Longitudinal assessments seems to be the best way to have a deeper knowledge on how performance main determinants act and affect the performance

Determinant factors of long-term performance development in young swimmers

To develop a performance predictor model based on swimmers’ biomechanical profile, relate the partial contribution of the main predictors with the training program, and analyze the time effect, sex effect, and time × sex interaction. 91 swimmers (44 boys, 12.04 ± 0.81 y; 47 girls, 11.22 ± 0.98 y) evaluated during a 3-y period. The decimal age and anthropometric, kinematic, and efficiency features were collected 10 different times over 3 seasons (ie, longitudinal research). Hierarchical linear modeling was the procedure used to estimate the performance predictors. Performance improved between season 1 early and season 3 late for both sexes (boys 26.9% [20.88;32.96], girls 16.1% [10.34;22.54]). Decimal age (estimate [EST] –2.05, P < .001), arm span (EST –0.59, P < .001), stroke length (EST 3.82; P = .002), and propelling efficiency (EST –0.17, P = .001) were entered in the final model. Over 3 consecutive seasons young swimmers’ performance improved. Performance is a multifactorial phenomenon where anthropometrics, kinematics, and efficiency were the main determinants. The change of these factors over time was coupled with the training plans of this talent identification and development program.info:eu-repo/semantics/publishedVersio

Longitudinal study in male swimmers: a hierarchical modeling of energetics and biomechanical contributions for performance.

The aim of this study was to assess the pooled and individual response of male swimmers over two consecutive years of training and identify the energetic and biomechanical factors that most contributed for the final performance. Nine competitive swimmers (20.0 ± 3.54 years old; 10.1 ± 3.41 years of training experience; 1.79 ± 0.07 m of height; 71.34 ± 8.78 kg of body mass; 22.35 ± 2.02 kg·m(-2) of body mass index; 1.86 ± 0.07 m of arm span; 116.22 ± 4.99 s of personal record in the 200 m long course freestyle event) performed an incremental test in six occasions to obtain the velocity at 4 mmol of blood lactate (V4) and the peak blood lactate concentrations (Lapeak) as energetics, and the stroke frequency (SF), stroke length (SL), stroke index and swim efficiency as biomechanical variables. Performance was determined based on official time's lists of 200 m freestyle event. Slight non-significant improvements in performance were determined throughout the two season period. All energetic and biomechanical factors also presented slight non-significant variations with training. Swimmers demonstrat-ed high inter-individual differences in the annual adaptations. The best performance predictors were the V4, SF and SL. Each unit of change V4, SF and SL represented an enhancement of 0.11 s, 1.21 s and 0.36 s in performance, respectively. The results show that: (i) competitive male swimmers need at least two consecutive seasons to have slight improvements in performance, energetics and biomechanical profiles; (ii) major improvements in competition performance can be accomplished by improving the V4, SF and SL based on the individual background. Key PointsElite swimmers are able to demonstrate slight changes in performance, energetic and biomechanical characteristics at least during two seasons of training;Additional improvements in competition performance can be accomplished by manipulating the V4, SF and SL based on the individual background.Each unit of change V4, SF and SL represent an enhancement of 0.11 s, 1.21 s and 0.36 s in performance, respectively

Frequência de anticorpos antiparvovírus B19 em artrite reumatoide e lúpus eritematoso sistêmico

AbstractObjectiveTo determine the frequency of antiparvovírus B19 (B19) antibodies in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and the possible correlation of anti-B19 seropositivity with disease activity and quality of life.Patients and methodsSerum samples from 57 patients with RA, 45 with SLE and 65 healthy controls were used. We applied protocol with clinical data, and the Disease Activity Score 28 (DAS 28), Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Health As- sessment Questionnaire (HAQ) indexes. The anti-B19 serology was done by enzyme-linked immunosorbent assay (ELISA).ResultsThe mean age of patients was 42.74 ± 14.09 years, and of controls was 38.38 ± 13.42 years. 79 patients had active disease (77.5%), and 23 had inactive disease (22.5%). Anti-B19 (IgG) was positive in 49 (86.0%; CI 95% 77.0 – 95.0) RA patients, 38 (84.4%; CI 95% 73.9 – 95.0) SLE patients, and 40 (61.5%; CI 95% 49.7 – 73.4) controls (p = 0.002). Anti-B19 (IgM) was posi-tive in 3 (5.3%; CI 95% 0.0 – 11.1) RA patients, in 7 (15.6%; CI 95% 5.0 – 26,2) SLE patients, and in 1 (1.5%; CI 95% 0.0 – 4.5) control (p = 0.011). There was no correlation of anti-B19 reactivity with disease activity and with DAS 28, HAQ and SLEDAI indexes.ConclusionThis study demonstrated that the studied population is exposed to infection by B19, which demands attention with its manifestations, especially among patients at great- est risk, such as those immunosuppressed

Linking selected variables with direct and indirect effect on young swimmer's performance

One of the main goals of swimming research is to identify the scientific domains and/or variables that predict swimming performance in children (i.e., young athletes) in the perspective of detecting future talents (1). Nevertheless, research in young athletes should be less invasive, expensive and timeconsuming than in adult/elite counterparts (2). In this sense, several authors (2-4) on regular basis estimate and/or measure variables in different scientific domains (i.e., anthropometric, hydrodynamic, kinematical and energetic) that are easy to collect and might predict performance and/or detect talented swimmers.info:eu-repo/semantics/publishedVersio

Caracterização fenológica de genótipos de uvas de mesa do Banco Ativo de Germoplasma da Embrapa Semiárido.

Com este trabalho, objetivou-se avaliar o comportamento fenológico de 109 genótipos de uvas de mesa do Banco Ativo de Germoplasma da Embrapa Semiárido durante o primeiro e o segundo semestres de 2010. O experimento foi instalado no Campo Experimental de Mandacaru, Juazeiro, BA. Considerou-se a média em número de dias de duas safras (2010.1 e 2010.2) para a ocorrência das principais fases fenológicas. Foram avaliados 76 genótipos de uvas de mesa com semente e 33 genótipos de uvas sem semente. Os genótipos foram classificados em precoce, mediano e tardio. Entre os genótipos de uvas com semente, houve um predomínio de genótipos tardios, tanto nos ciclos do primeiro quanto do segundo semestre de 2010, correspondendo a 60% e 64% dos genótipos, respectivamente. A maioria dos genótipos de uvas sem sementes apresentaram ciclo fenológico mediano nos dois semestres do ano. A duração das fases fenológicas sofreu variações de acordo com os ciclos do primeiro e segundo semestre, como também de acordo com o genótipo
