A new approach to average consensus problems with multiple time-delays and jointly-connected topologies

This paper investigates average consensus problem in networks of continuous-time agents with delayed information and jointly-connected topologies. A lemma is derived by extending the Barbalat's Lemma to piecewise continuous functions, which provides a new analysis approach for switched systems. Then based on this lemma, a sufficient condition in terms of linear matrix inequalities (LMIs) is given for average consensus of the system by employing a Lyapunov approach, where the communication structures vary over time and the corresponding graphs may not be connected. Finally, simulation results are provided to demonstrate the effectiveness of our theoretical results.

社会认知视域下的大学生过激行为探析

当前,在大学生群体中存在着以自杀、自残、杀人、伤人为主要表现形式的过激行为,一方面,由于大学生所处的社会背景,包括家庭缺乏民主平等的沟通环境,学校对学生社会认知能力的培养严重不足,社会大环境中网络等媒体充斥不健康的影响因子,等等.另一方面,由于大学生认知特点表现出"自我中心"的心理特征,又正处于自我同一性与角色混乱的心理矛盾期,极易造成认知失调和在社会认知问题上产生归因偏差,最终引发过激行为,因而建立大学生过激行为的预警机制对于建设和谐校园具有重要的现实意义.     

Diversified professionalism of physical education teachers in the Asian context of Hong Kong

This study investigates the socialization and professional experiences of primary school physical education teachers (PSPETs) in the Asian context of Hong Kong. A qualitative research design is adopted. The researcher used semi-structured interviews, supplemented by documentary sources (diaries) for conducting data collection. Eleven PSPETs participated in this study. Data were analysed through open axial and selective coding. The concepts of organizational sensitivity, sources of satisfaction, dealing with influential persons or critical incidents, status of the profession, educational reform as a trend, and versatile roles are revealed in the theory of ‘Diversified Professionalism’. The substantive theory thus contributes to an increased appreciation of the PSPETs’ work and to the literature on physical education teachers’ professionalization and professionalism.     

英文情书与推销信函中人称的人际功能比较研究

受不同语旨的影响,为满足不同读信人的需求,写信人会对人称资源做出不同选择。英文情书中,第一人称直述,引出话题并引导读信人参与话题;第二人称对读信人产生拉力,能加强写信人与读信人的亲密关系;第三人称虽然较少使用,但丰富了人称意义的多种可能性。英文推销信中,第一人称削弱了写信人的权势地位,表达了写信人以期与读信人进行平等、友好的对话意愿;第二人称使两者实现了面对面的交流;第三人称的指代则使推销信更简洁、客观。

SVC bitstream adaptation in MPEG-21 multimedia framework

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil…
