Criação, proteção e uso legal de informação em ambientes da World Wide Web

Um número cada vez maior de produtores de conteúdo informacional, embora de acordo com os padrões culturais prevalecentes nem sempre seja considerado qualitativamente favorável, evidencia uma nova configuração cultural exponencialmente representativa no fluxo da informação em que o indivíduo, que não há muito tempo era um mero consumidor de conteúdo intelectual, é agora também um participante ativo na criação desses conteúdos. Os indivíduos que lidam com essas novas formas de produzir, disseminar e usar conteúdos informacionais devem estar conscientes das diferenças que se impõem quando a informação é digital. Eles devem conhecer as implicações quanto ao fluxo da informação e seus aspectos simbólicos, bem como saber sob quais condições a lei de direitos autorais estabelece que essas práticas devam acontecer.

Application of Reactions Norms in Study of Genotype Environmental Interaction for Milk Yield of Buffaloes

The aim of this study was to estimate genetic parameters for milk yield (MY) in buffaloes using reaction norms. Model included the additive direct effect as random and contemporary group (herd and year of birth) were included as fixed effects and cow age classes (linear) as covariables. The animal additive direct random effect was modeled through linear Legendre polynomials on environment gradient (EG) standardized means. Mean trends were taken into account by a linear regression on Legendre polynomials of environmental group means. Residual variance was modeled trough 6 heterogeneity classes (EG). These classes of residual variance was formed : EG1: mean = 866,93 kg (621,68 kg-1011,76 kg); EG2: mean = 1193,00 kg (1011,76 kg-1251,49 kg); EG3: mean = 1309,37 kg (1251,49 kg -1393,20 kg); EG4: mean = 1497,59 kg (1393,20 kg-1593,53 kg); EG5: mean = 1664,78 kg (1593,53 kg -1727,32kg) e EG6: mean = 1973,85 kg (1727,32 kg -2422,19 kg).(Co) variance functions were estimated by restricted maximum likelihood (REML) using the GIBBS3F90 package. The heritability estimates for MY raised as the environmental gradient increased, varying from 0.20 to 0.40. However, in intermediate to favorable environments, the heritability estimates obtained with Considerable genotype-environment interaction was found for MY using reaction norms. For genetic evaluation of MY is necessary to consider heterogeneity of variances to model the residual variance.

Polymorphisms in Osteopontin Gene in Amazon Buffaloes

The aim of this work was to identify polymorphisms in the osteopontin gene. It was used in this experiment 306 male buffaloes, older than 18 months, bred in two farms, one in the State of Amapa and the other farm in the State of Para. There was identified three SNP polymorphisms for the region amplified by the primer OS4 (5'upstream) and four SNP polymorphisms for the region amplified by the primer OS9 (exon 5 to exon 6). The polymorphisms were in positions 1478, 1513 and 1611 in the region amplified by OS4 and positions 6690, 6737, 6925 and 6952 in the region amplified by OS9. These data indicate that the osteopontin gene is important because it can have a substantial influence on the reproductive traits of male buffaloes.
