CSRP's Impact on low-income preschoolers' preacademic skills: self-regulation as a mediating mechanism     

Raver CC  Jones SM  Li-Grining C  Zhai F  Bub K  Pressler E 《Child development》2011,82(1):362-378

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.  相似文献

Optimal ϵ -stealthy attack in cyber-physical systems     

Weiwei Tu  Jiuxiang Dong  Ding Zhai 《Journal of The Franklin Institute》2021,358(1):151-171

This paper is concerned with the optimal stealthy attack problems of cyber-physical system, which is represented as discrete-time linear systems. It is considered that a deceptive attack assumed to be able to hijack and modify the nominal control signals from the controller-actuator channel with the metric of ? -stealthiness. Different from the existing literatures, some optimal attack strategies with objectives such that maintaining a fixed level of stealthiness and achieving the maximized performance degradation are designed under some constraints. It is further derived that the results of ours are more relaxed than some methods proposed before. Finally, some numerical simulations are given to illustrate the validity of the theoretical results.  相似文献   

Bivariate grid-connection speed control of hydraulic wind turbines     

Chao Ai  Wei Gao  Lijuan Chen  Jiawei Guo  Xiangdong Kong  Andrew Plummer 《Journal of The Franklin Institute》2021,358(1):296-320

The requirement for An electrical grid-connected wind turbine is that the synchronous generator speed is stable within a required speed range for the electrical grid. In this paper, a hydraulic wind turbine (HWT) system is considered, and the working principle and working conditions of the HWT are introduced. A novel speed control method is proposed in this paper, using both a proportional flow control valve and a variable displacement motor, which are adjusted in combination to control the speed of the HWT. By establishing a state space model of the HWT and solving the nonlinear system with a feedback linearization method, a bivariate tracking controller is constructed to realize accurate speed control under fluctuating wind speed and the load disturbance conditions. The effectiveness of the control method is verified by simulation, but experimental results highlight problems with the method. The theoretical controller is simplified to reduce sensitivity to measurement noise and modeling error. The control effect has been improved to some extent, but it is limited. Based on these results, combined with the sliding mode variable structure control method and the feedback linearization method to solve the problem of measurement noise and modeling error, and the effectiveness of the control law is finally verified experimentally. It lays a theoretical foundation for the practical application of HWT.  相似文献   

风险社会背景下司法能动的正当性及其限度     

沈寨 《贵阳师范高等专科学校学报》2011,(1):21-24

风险社会的来临对法律的发展提出了挑战,也为司法能动提供了空间。风险的不确定性放大了法律的缺陷、风险发生时社会纠纷的激增以及风险社会对常态社会的诸多逆反等都为司法能动提供了正当性基础。尽管如此,风险社会中司法能动仍有一些限度和界限。风险发生时司法能动的预防功能有所减弱,同时司法能动在风险责任认定上也存在一定缺陷。风险社会的司法能动必须遵循司法的本质和规律,只有这样才能最终实现社会的公正。  相似文献

中国古代教育哲学中的理想人格与大学生理想人格的完善     

石丽娟  张会兰  张春生 《保定学院学报》2011,24(2):116-119

当代大学生人格总体状况良好,他们追求自我完善,学习积极主动,既追求个人的发展,又关心国家的进步,但也存在一定的人格缺陷。加强对大学生理想人格的培养和教育,形成家庭、学校和社会三位一体的培养机制,提升大学生理想人格的自我修养的自觉性,是整体提升大学生素质的重要途径。  相似文献
