Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.     

四能级原子自发辐射的量子相干特性

研究四能级原子的自发辐射。原子激发态是不稳定的,其必然会自发地向低能级衰变,产生自发辐射现象。本文针对四能级原子仅存在自发辐射的情况,基于量子力学和Kraus算子理论,利用约化密度矩阵方法,得到四能级原子自发辐射的密度矩阵元演化规律,从而分析量子态相干特性。     

从视觉文化角度对电影的解读

明时代是以字的出现作为标志的。字时代把人类对于事物的直接观察的重要性．让渡给了对于字意义的体会。这种强调对意义把握的明，成为人类进步的骄傲，也成为束缚人自由思考、自由感受的藩篱。以电影为发端的视觉化的出现，首次逆转了明的演进趋向。这种趋向在电视和电脑网络的信息传达中得到进一步强化和深化。     

网络时代图书馆对读者的道德文化教育

步入网络时代的高校图书馆，要重视研究网络化，探索对读进行道德教育的新特点；要善于依托网络环境，重塑大学生们新的精神生活；要不断开发网络明，完成对读道德化教育现代化的现实转换，努力促进图书馆教育职能的发挥，开创图书馆工作的新局面。     

科举学学科的衍生分化:理论、模型与范例(上)

跨学科研究是科举学成为一门科学化学科的重要而独特的方法论。学科之间的整合和衍生分化是科举学跨学科研究的客观要求,也是推动科举学分支学科领域知识创新与转化、生产与增长、发展与壮大的重要方法。通过分析科举学学科衍生分化的基本理论和特点,优化适用于科举学等新兴学科知识衍生分化的"网络模型"及其演化机理,并在理论到实践维度上对科举学分支学科领域创新知识的内部、外部和交叉复合衍生分化进行了应用探索,据此形成了许多科举学分支学科领域的衍生分化范例,这些范例的形成、发展与成熟有助于反思学科衍生分化方法的成效及未来动向。     

关于高校学风建设的探讨

当前,学风建设是各个高校普遍存在的问题,所以,在长期的教学工作和教学管理工作中笔者关注学校学风状况,收集教师、学生及学生家长反馈的意见,分析存在不良学风现象的原因,探讨应对的办法,希望能对学风建设有所帮助.

Improving the precision of the keyword-matching pornographic text filtering method using a hybrid model

With the flooding of pornographic information on the Internet, how to keep people away from that offensive information is becoming one of the most important research areas in network information security. Some applications which can block or filter such information are used. Approaches in those systems can be roughly classified into two kinds:metadata based and content based. With the development of distributed technologies, content based filtering technologies will play a more and more important role in filtering systems. Keyword matching is a content based method used widely in harmful text filtering. Experiments to evaluate the recall and precision of the method showed that the precision of the method is not satisfactory, though the recall of the method is rather high. According to the results, a new pornographic text filtering model based on reconfirming is put forward. Experiments showed that the model is practical, has less loss of recall than the single keyword matching method, and has higher precision.
