TL;DR: This article extends the watch-and-comment paradigm as the seamless capture of an individual's comments so that corresponding annotated interactive videos be automatically generated and employs annotations as simple containers for context information by using them as tags in order to organize, store and distribute information in a P2P-based multimedia capture platform.
Abstract: The literature reports research efforts allowing the editing of interactive TV multimedia documents by end-users. In this article we propose complementary contributions relative to end-user generated interactive video, video tagging, and collaboration. In earlier work we proposed the watch-and-comment (WaC) paradigm as the seamless capture of an individual's comments so that corresponding annotated interactive videos be automatically generated. As a proof of concept, we implemented a prototype application, the WaCTool, that supports the capture of digital ink and voice comments over individual frames and segments of the video, producing a declarative document that specifies both: different media stream structure and synchronization.In this article, we extend the WaC paradigm in two ways. First, user-video interactions are associated with edit commands and digital ink operations. Second, focusing on collaboration and distribution issues, we employ annotations as simple containers for context information by using them as tags in order to organize, store and distribute information in a P2P-based multimedia capture platform. We highlight the design principles of the watch-and-comment paradigm, and demonstrate related results including the current version of the WaCTool and its architecture. We also illustrate how an interactive video produced by the WaCTool can be rendered in an interactive video environment, the Ginga-NCL player, and include results from a preliminary evaluation.

TL;DR: In this article, an oriented hematite undoped photanode was synthesized by a single chemical route step at low temperature and with a short reaction time, which is not inconsistent with thermodynamical parameters extracted from the Pourbaix diagram.

TL;DR: In this article, a study of 120 professores at the Ensino Fundamental de escolas publicas in Portugal found that 84.2% of the professores avalia a voz como a boa, apesar de enfrentarem dificuldades ao falar, especialmente quando se trata de falar forte em ambientes ruidosos e do ar acabar rapido e precisar respirar muitas vezes enquanto fala.
Abstract: TEMA: relacao voz e qualidade de vida. OBJETIVO: avaliar o impacto da voz na qualidade de vida de professores do Ensino Fundamental de escolas publicas. METODO: aplicacao do questionario protocolo de Qualidade de Vida e Voz (QVV) em 120 professores. A analise engloba o calculo do Dominio Global (questoes de 1 a 10), a analise descritiva das questoes e o calculo dos coeficientes de correlacao de Spearman entre o Dominio Global, a questao "como avalia a sua voz", a idade, o tempo de magisterio e a carga horaria de trabalho. RESULTADOS: a media do Dominio Global e 84,2 a maioria (49,2%) avaliou a voz como boa, apesar de enfrentarem dificuldades ao falar, especialmente quando se trata de falar forte em ambientes ruidosos e do ar acabar rapido e precisar respirar muitas vezes enquanto fala (questoes 1 e 2, respectivamente). A questao isolada apresentou correlacao linear significativa com todas as questoes do QVV, ao passo que idade e carga horaria nao apresentaram correlacao significativa com nenhuma das questoes. Tempo de magisterio apresentou correlacao com as questoes 2 e 5, relacionadas a problemas como falta de ar e depressao, respectivamente. O impacto da voz na qualidade de vida evidencia-se, portanto, no uso da voz em forte intensidade, na incoordenacao pneumofonica, no trabalho e nos sentimentos negativos, diretamente relacionados as necessidades vocais da categoria. CONCLUSAO: o impacto da voz sobre a qualidade de vida e trabalho e ainda pouco percebido pelos professores, que tem necessidades vocais que demandam acoes de promocao da saude que levem em conta a relacao entre voz e qualidade de vida do professor.
