Ferramentas de suporte à edição colaborativa visam contribuir para o desenvolvimento da expressão escrita, habilidade tão necessária em todas as disciplinas e níveis educacionais. Este artigo propõe um estudo sobre editores colaborativos e apresenta uma ferramenta web simples que adiciona novas funcionalidades de coordenação, cooperação e comunicação ao Google Docs. A ferramenta desenvolvida possibilita a criação de um fórum de discussão cujos tópicos estejam vinculados a documentos em processo de edição. Além disso, ela permite a criação de uma árvore de alocação de tarefas que auxilia no gerenciamento das atividades do grupo envolvido na edição colaborativa de documentos. A ferramenta é operacional e está disponível para usuários através de sua instalação em servidor local.
It is well established that different light wavelengths affect broiler behavior. The present study aims to evaluate the effect of four light wavelengths on broiler behavior from 1 to 42-days of age. Birds were housed at a stocking density of 13 birds/m2, in 32 boxes of 1.56 m2. The experimental design was a completely randomized factorial of 4x2 (four colors x two sexes), with four replicates. Behavioral variables were accessed through cameras and observed in person thrice a week for 30 min per day in three different periods. Data was organized according to age groups and analyzed by data mining approach with the different light wavelengths as the classes. Natural behavior of male broilers reared in environments with green. Blue light was more relevant to the classification of male broilers behavior (96.9 and 96.9% accuracy and 0.8 and 1.0 of class precision of behavior classification, respectively). Blue and green lights affected the behavior of male broilers starting at 7-days of age, increasing the presence at the bird feeder, and reducing the idle period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
