Time spent on the Internet by multicultural adolescents in Korea

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.     

互联网上的使用与满足——一项关于大学生网络使用的实证研究

“使用-满足”理论是一种强调受众主体性的传播效果理论。通过整群抽样的方式,对南京的大学生进行了问卷调查,结果证明互联网存在着较为明显的“使用-满足”现象。调查对象不但对网络的各项服务功能表现出一定的满足感,在行为上也体现出了对网络的依赖性。调查还发现,老网民时网络的满意度较低。     

Addressing Science Teacher's Initial Perceptions of the Classroom Uses of Internet and World Wide Web-Based Resource Materials

Teachers are often subject to considerable pressure to utilize the Internet and the World Wide Web (WWW) in their classrooms. Research suggests, however, that many teachers may not be prepared to make meaningful educational use of the resources available on the Web. This study examines the initial perceptions of educational value of science resource materials available on the WWW, as gathered from a group of science teachers participating in the West Virginia K-12 RuralNet project summer workshop training. The results suggest that while most teachers feel that the WWW does provide a large number of good science resources for educators, few teachers are prepared to make use of these materials in their own classrooms. Possible solutions to this problem include long term training in both technical and curriculum integration, classroom practice during training, and the support of an on-line community of peers.

大学之用

一定的大学理念乃是一定时代的产物。大学的社会存在在变化，大学理念也必须相时而变。未来大学将必须重新分类：一类是所谓名牌大学，世界一流大学，其主要之用在知识贡献。另一类是所谓大众大学，其主要之用在人才支持，即培养有学识、有技能的、数量必定宏大的劳动者。今天我们研讨大学理念，关键在明白大学之用。     

Uses of Narrative

What concerns me here are the qualities which fictional narrative shares with that inner and outer storytelling that plays a major role in our sleeping and waking lives. For we dream in narrative, remember, anticipate, hope, despair, believe, doubt, plan, revise, criticize, construct, gossip, learn, hate, and love by narrative. In order really to live, we make up stories about ourselves and others, about the personal as well as the social past and future. Barbara Hardy, 'Towards a Poetics of Fiction'
