The islands of Mauritius and Réunion have contrasting educational policies. This article examines, from a comparative perspective, not only the impact of political decisions on education but also the way in which the different educational systems in the two islands affect the democratisation of learning. In order to do this, the authors compare the educational trajectories of different pupils from a range of schools in Mauritius and Réunion. Using a combination of quantitative and qualitative approaches, it is possible to show that the expected social effects are moderated in the course of teaching. While the adoption of mass education is a prerequisite for democratisation, it must be recognised that systems also operate selectively with regard to variables such as sex, age or social origin, depending on what transpires in schools on a daily basis. 相似文献

In the present paper, the problem of designing a global sliding mode control scheme based on fractional operators for tracking a quadrotor trajectory is investigated. The model of the quadrotor system is given with disturbances and uncertainties. To converge in short finite time of the sliding manifold, a classical quadratic Lyapunov function was used and also a global stabilization of the quadrotor system is ensured. The proposed controller can be ensured the robustness against external disturbances and model uncertainties. Some scenarios are illustrated in this paper. Finally, a comparative study to three other controllers is provided to show the validity and feasibility of the proposed method. 相似文献
