“…In that case, the conclusions of this section would not be applicable. Nevertheless, there are orbits, such as polar ones, in which the magnetic field rotates enough to ensure that dissipation along the orbit will occur in all directions [25].…”

“…The dependence on the variable can be eliminated with the following change of variable: (23) Resulting in the following set of equations: (24) The equilibrium attitude will occur only for certain values of angle θ. Therefore, a fourth equation that describes its variation may be used in the space state: (25) with ( 22) and ( 25) the following space state matrix for the variable Q can be constructed: (26) This state space system has an equilibrium point at: (27) This equilibrium point corresponds to a solution where the magnetic moment only produces torque about the y body axis, and the angular velocity increases until the spinning torques (that are independent of spin velocity) and despinning torques (that are proportional to spin velocity) compensate each other. Linearizing around that point: (28) where can be considered almost constant near the equilibrium point, because if θ, ω x and ω z are close to zero, therefore also (see equation ( 14)).…”

As an important form of second language input, videos have been given much attention by both language teachers and SLA researchers. Second language learning videos typically come in two forms: live-action videos (with human actors in realistic settings) and animation videos. In this paper, we report on an empirical study on the relative merits of these two kinds of videos for beginning learners of Chinese. A total of 82 participants took part in this research as students in a Beginners’ Chinese Language course at a university in Singapore. Each participant attended four learning sessions, two of which being based on live-action videos and another two on animation videos. Post-tests showed that the efficacy of the two kinds of videos differed between students who had had richer community exposure to Mandarin before attending the course and students who did not have such exposure. The former group performed significantly better than the latter after attending live-video sessions. However, students in the latter group reported a preference for animation videos during the post-interviews due to the more well-controlled quality of the soundtracks (i.e., less noisy background).

Proficiência E Compreensão De Telenotícias Em Língua Estrangeira

O presente estudo investiga a relação entre proficiência em inglês como língua estrangeira e compreensão de telenotícias em inglês. Três aspectos das telenotícias foram investigados: uso de imagens, existência de redundância e presença de input oral e acessível. Os resultados indicam que estes três aspectos parecem auxiliar a compreensão. Os achados podem ajudar a questionar a crença entre professores de inglês que vídeos de telenotícias são adequados somente como material para alunos mais avançados. O estudo conclui, em linhas gerais, que, dependendo das características do vídeo, a compreensão por alunos menos proficientes pode ser facilitada.
