侠文化早已深入人心,作为一个重要的文化现象,它已经对平民,进而对社会产生了重要的影响, 本文从平民的慕侠思想,群体的特征,侠与主流社会的关系,现代传媒对侠文化的推广,平民眼中侠形象的变异等多方面对侠对平民的进而对社会的影响作了剖析.     

Audio steganalysis based on ＂negative resonance phenomenon＂ caused by steganographic tools

INTRODUCTION With the rapid progress in the Internet and ex- panded area of multimedia technology, steganogra- phy and steganalysis as subfields of information se- curity have developed rapidly and drawn more and more attention. Steganography is the art of hiding and transmitting data through apparently innocuous car- riers in an effort to conceal the existence of the secret data (Peticolas et al., 1999). While steganalysis, the countermeasure to steganography, is an art that de- tects ev…

How does collaboration affect researchers’ positions in co-authorship networks?

Collaboration usually has a positive effect on researchers’ productivity: researchers have become increasingly collaborative, according to recent studies. Numerous studies have focused on enhancing research collaboration by recommendation technology and measuring the influence of researchers. However, few studies have investigated the effect of collaboration on the position of a researcher in the research social network. In this paper, we explore the relationships between collaboration and influence by social analytical methods, which are pertinent to analyzing the network structure and individual traits. We evaluate three aspects of the researchers’ influence: friendship paradox validation, social circle, and structure of a researcher's ego network. Furthermore, the ”six degrees of Bacon number” theory, generalized friendship paradox, and triadic closure theory are introduced to support our analysis. Experimental results show that collaboration can help researchers increase their influence to some extent.     

变易学习理论：理论基础、概念内涵和实践形式

变易学习理论是解释学习中差异的理论,在当代学习研究中受到重视。其方法论基础是现象描述分析学;其涵义体现在认为学习即是意识到了学习内容的重要方面,学习者经验或理解事物的方式依赖于意识到并能进行区分的那些方面;而其实践形式是课堂学习研究,即以变易学习理论为依据,教师及同伴进行课堂学习研究,以支持学生对学习内容的重要方面的识别。从而,可以理解到变易学习理论对有效的课堂教学、学习评价以及校本课程开发的指导意义。
