多元智能理论在英语专业教学中的应用     

杨静 《安顺师范高等专科学校学报》2015,(3)

多元智能理论阐述了每个人的智能是多元的,智力不仅指一种能力或仅以某一种突出能力为中心的能力,而是多种智力的相互组合、综合利用。在英语专业本科教学中,多元智能的重要性更应该得到全方位的体现,只有全面开发学生的各种智能,才能让他们在专业知识的学习上更加科学、合理、有效。  相似文献

Child maltreatment among boy and girl probationers: Does type of maltreatment make a difference in offending behavior and psychosocial problems?     

《Child abuse & neglect》2015

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n = 231), physically abused (n = 1,568), neglected (n = 1,555), exposed to multiple forms of maltreatment (n = 1,767), and non-victims (n = 8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed.  相似文献   

一种基于关系视频盲水印算法     

鲁晓辉 《宁波职业技术学院学报》2015,(3)

针对视频水印的特征,提出一种利用视频帧采样点均值曲线相交性确定嵌入帧的方法：在水印信息嵌入时,利用嵌入帧三个亮度最大分块位置关系和DC值大小实现每帧2bit信息的嵌入。实验证明,该算法对常规攻击具有良好的鲁棒性。  相似文献   

高校信息技术能力与办学绩效关系的实证研究     

曹郑玉  张守华 《现代远程教育研究》2015,(1):90-97

大量信息技术(IT)投资和应用所引发的"生产率悖论"问题的出现,使人们逐渐认识到IT本身并不一定能给组织带来更好的绩效。资源观理论认为,IT资源与IT能力是两个不同的概念。提高IT能力,才是发挥信息技术战略价值的关键所在。从能力视角对IT能力进行定义,可以将其分为技术性IT能力和管理性IT能力。技术性IT能力包括硬件兼容能力、软件模块化能力、网络连接能力和IT人员技术能力四个子维度;管理性IT能力包括管理能力、关系协调能力和战略匹配能力三个子维度。以工信部所属7所高校为样本,利用结构方程模型和多元回归分析方法,对高校IT能力与办学绩效关系的理论模型进行实证研究。结果显示,高校IT能力由技术性IT能力和管理性IT能力构成,管理性IT能力较技术性IT能力更显著、正向地直接影响高校的办学绩效;同时,管理性IT能力对技术性IT能力也产生了正向影响。  相似文献   

Concreteness fading in learning secondary school physics concepts     

《Learning and Instruction》2022

Concreteness fading has been proposed as a general instructional approach to support learning of abstract mathematics and science concepts. Accordingly, organizing external knowledge representations in a three-step concrete-to-idealized sequence should be more beneficial than the reverse, concreteness introduction, sequence. So far, evidence for the benefits of concreteness fading come mainly from studies investigating learning of basic mathematics concepts. Studies on learning natural science concepts are scarce and have not implemented the full three-step-sequence. In an experimental classroom study (N = 70), we compared concreteness fading and concreteness introduction in high school science education about electromagnetic induction using a detailed assessment. Furthermore, we explored whether these sequences differentially affect the use of the different representations during instruction. Both sequences were equally effective and there were no differences in using the representations. We discuss why our results question the proposed advantages of concreteness fading and highlight conceptual differences and learning goals across domains.  相似文献

Natural surface design for sliding mode control with multiple discontinuous inputs     

Pedro Acosta 《Journal of The Franklin Institute》2014

It is well known that sliding mode control is based on the definition of an invariant manifold, where the system dynamics are forced to in a finite time. Such a manifold is somewhat arbitrarily defined, as long as the system dynamics are stable on it. Computational and control effort may vary depending on selected manifold. Obviously, if a system has naturally acceptable stable dynamics around a desired equilibrium point, no control is needed unless uncertainties or disturbances are present. It would be desirable that if such a system had uncertainties or disturbances, the control effort be designed only to overcome the effect of such factors. For a system with first order dynamics and affine control input, designing a sliding mode control overcoming only such uncertainties or disturbances is a trivial task. When a higher order dynamics system is involved, unit control may be used, where the input control signals are not discontinuous, but when only discontinuous control inputs are available, a design approach is not readily available. In this paper, taking advantage of the natural stable dynamics of a system, a sliding mode control approach is introduced for designing multiple discontinuous control inputs, where the control effort overcomes only uncertainties, disturbances or unstable dynamics. Two illustrative examples are given in order to show the feasibility of the method.  相似文献

基于混沌和分维的盲水印算法     

张健  刘琳  付勇智 《人天科学研究》2014,(2):63-66

把分形维数理论应用到数字水印中,提出了基于Chebysher混沌置乱和分形维数的自适应数字图像水印算法。首先将载体图像分块,计算每个小块的分形维数。然后将载体图像进行分块DCT变换,使用改进的邻域平均法,将经过混沌置乱后的水印信息嵌入到图像的DCT域中,并根据该小块的分形维数调节嵌入强度,实现了水印信息的自适应嵌入。提取水印时,实现了完全盲提取。MATLAB仿真结果表明,该算法具有较好的不可见性,对常见的图像处理攻击具有较好的鲁棒性。  相似文献
