基于离散小波变换和图像分存的数字水印算法

针对数字图像版权保护的问题,设计了一种基于离散小波变换和图像分存的数字水印算法。算法将水印信息随机嵌入到图像的小波分解中频系数中,并且使用纠错编码和置乱加密,以增强算法的安全性。实验结果表明该算法是有效的。

论中国画的写意精神

写意是中国传统绘画最主要的特征。儒、释、道相互影响,相互渗透,对中国画文化品格及写意精神的生成、培养和发展,起着十分重要的作用。“意”是作者发挥性灵感想,于画外寄托的高情雅致。是画家参与造化之机,脱却胸中尘俗的、极纯粹的心境。以书入画——书写性是写意画的不二门法。     

光学衍射仿真软件的设计与实现

分析了在计算机模拟光学衍射过程中,把连续的菲涅耳衍射积分公式离散化为离散菲涅耳变换的方法,并用离散菲涅耳变换计算出任意形状衍射屏的衍射光场．应用MATLAB的GUI工具开发了光学衍射仿真软件,它不仅能模拟常见光孔的衍射,也能对如刀片等复杂形状衍射屏的菲涅耳衍射和夫琅禾费衍射进行模拟,有助于理解衍射光在传播方向上近场衍射和远场衍射的不同和衍射花样的分布特征．

Academic self-concept and emotion relations: Domain specificity and age effects

The present study investigated the relations between academic self-concepts and the emotions of enjoyment, pride, anxiety, anger, and boredom as experienced in mathematics, physics, German, and English classes (N = 1710; grades 8 and 11). In line with our hypotheses derived from appraisal-based emotion theories and self-efficacy research, within-domain relations between self-concepts and emotions were relatively strong and notably stronger within quantitative domains (mathematics and physics) than verbal domains (German and English). Also consistent with our hypotheses, stronger relations between self-concepts and emotions were observed among older students. Self-concept and emotion relations further differed as a function of the specific emotion assessed, with pride showing the strongest and boredom the weakest relations with academic self-concepts in the four domains assessed. Methodological and educational implications as well as directions for future research are discussed.     

Teacher alienation in Hong Kong

Teachers’ negative emotions began to receive attention in the Hong Kong context in the mid-1990s. As negative emotions may affect both teachers’ well-being and the quality of their teaching, Hong Kong education policy-makers and educators have used psychological approaches to determine the reasons why teachers experience negative feelings. However, these approaches fail to accommodate the social causes of negative emotions. Therefore, this study investigates the possible social causes of teachers’ negative emotions from the perspective of alienation theory. In-depth interviews with 21 teachers in Hong Kong reveal that Hong Kong teachers may be suffering from alienation (characterised by a sense of powerlessness, meaninglessness, isolation, and self-estrangement) due to their experiences of teaching, their employment status, and their structural position in schools, which are related to the occupational and organisational structure of teaching. The findings also indicate that patterns of alienation may differ between more and less experienced teachers.     

论公共教育学课程内容的重建

现行教育学课程内容存在的主要问题有:课程目标定位过于倚重知识或技能,忽视专业意识和职业情感的培养;课程内容选择贪多求全,游离具体而真实的教育情境;课程内容组织缺乏对教育问题和学生经验的关切。公共教育学课程内容设计应关注情感目标、情境创设和模块整合。重建的教育学课程内容应体现生动、活泼的特点,增加如案例讨论、人物介绍、名著鉴赏、活动设计等方式。     

民族声乐演唱中的七个基本问题

民族声乐演唱中有七个问题是基础性的问题,弄清这七大问题中的有关概念以及概念之间的内部联系,是迈向民族声乐的教学和演唱的一条成功的大道.反之.如果不能弄清这些基本问题,学习民族声乐就会寸步难行,甚至产生各种嗓音疾病.这七大基本问题分别是:一、民族声乐演唱的基础--歌唱的气息,二、民族声乐演唱的标尺--共鸣,三、民族声乐演唱的关键--打开喉咙,四、民族声乐演唱的核心--咬字吐字,五、民族声乐演唱的难点--真假声结合,六、民族声乐演唱的目的一声情并茂,七、民族声乐演唱的必然阶段--字声结合.
