安阳灵泉寺石窟档案艺术价值探析--以大住圣窟二神王图像为例

石窟档案是历史文化遗产和非纸质档案的特殊结合体,在我国古代历史档案中占据着非常重要的地位。安阳灵泉寺石窟是中国石窟体系中的重要代表,其中大住圣窟窟门两侧的"那罗延神王"与"迦毗罗神王"浮雕图像,造型精美,刻画精细,无论尺度和样式,均为国内石窟中罕见。本研究利用档案学的研究方法,从鸟翼冠、着装、脚踩神兽三方面对二神王图像的艺术价值进行分析,探讨其图像来源。     

用户生成性学习资源开发与利用:基于传播要素视角的调查与分析

随着Web2.0技术的兴起,用户生成性学习资源成为数字化学习资源开发与利用的新视角,对数字化学习资源建设产生了很大影响。本研究基于传播要素视角对用户参与开发利用生成性学习资源的动因和行为进行了调查分析。研究发现,用户由于受自身信息素养、兴趣爱好、平台资源类型和数量、资源的质量等因素的制约和影响,其开发和利用生成性学习资源的行为在驱动因素、参与频度、互动深度等多个维度呈现出不同的水平和特征。提高用户生成性学习资源的开发效率、开发质量和利用效果,应提高用户信息素养、激励用户积极参与、完善资源质量控制机制并建立有效的资源利用模式。本研究对于推动用户生成性学习资源的建设和发展,具有积极的理论意义和重要的实践指导价值。

论方贞观清寒诗风的形成

清代诗人方贞观,作为桐城方氏文化的继承者,即使深受《南山集》案的影响,依旧诗文不辍。作为方氏一员,他的诗歌在学习孟郊诗风的基础上,描写秋景,书写真情和闲居生活,展现着自己的清寒诗风。     

Reading attitudes in Vietnam: Initial study of the early school years

Whereas cognitive and linguistic factors for learning to read have been extensively studied, less is known about affective factors including children’s attitudes toward reading. Studies primarily from English-speaking and Western countries show gradual declines in reading attitudes in elementary school (McKenna et al., Reading Research Quarterly 30:626–639, 1995) and a positive association between reading attitudes and achievement (Petscher, Journal of Research in Reading 33:335–355, 2010). Children from Asian and African countries are underrepresented in this literature; whether these patterns can be generalized across cultures needs further investigation. This longitudinal study examined the reading attitudes of 84 children in Vietnam from grades 1 to 2 and their relations to reading performance, as measured by translated and adapted versions of the Elementary Reading Attitude Survey and Early Grade Reading Assessment, respectively. This sample from Vietnam showed a small decline in reading attitudes over time, particularly in attitudes toward academic reading. However, children on average reported feeling happy about reading in both grades. Correlations revealed different patterns of association between reading attitudes and performance based on the reading measure employed, grade level, and type of reading in question (academic versus recreational). In grade 2, reading attitudes explained unique variance in reading comprehension even after text fluency and mother’s education were considered. We present a margins plot to visualize the role of reading attitudes on reading comprehension. We discuss educational implications and future directions.

     

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control (ILC) is proposed in this paper. The developed analog ILC method and the high-gain property tracker design methodology are first combined to significantly reduce learning epochs and overcome the initial condition shift problem and discontinuous reference input in the traditional ILC. Besides, the proposed ILC improves the transient response and decreases the rate of weighting matrices Q$Q$ to R$R$ under the traditional linear quadratic tracker design. First, the off-line observer/Kalman filter identification (OKID) is used to determine the appropriate (low-) order system parameters and state estimator for the physical system with unknown system equation, so that the model-based PD-type ILC can be implemented for practical applications. Then, to improve the transient response and decrease the control effort, the proportional difference type (PD-type) ILC algorithm is combined with the high-gain property linear quadratic tracker (LQT) design to construct the high performance tracker for the model-based sampled-data systems. Furthermore, the discrete-time version high performance tracker design for the unknown stochastic sampled-data system via the iterative learning control method is proposed in this paper based on the Euler method and the digital redesign approach. Finally, some examples are given for illustrating the effectiveness of the proposed method.
