Age Differences in Online Social Networking: Extending Socioemotional Selectivity Theory to Social Network Sites

This article extends socioemotional selectivity theory to online social networking by examining age differences in the size and composition of Facebook networks across a wide age range of Facebook users (18 to 93 years old) in a nationally representative sample. Findings suggest increasing selectivity of Facebook social partners with age. Compared to younger adults, friend networks of older adults are smaller but contain a greater proportion of individuals who are considered to be actual friends. Moreover, a higher proportion of actual to total Facebook friends is associated with lower levels of social isolation and loneliness across the life span.     

Pathways to Expressive and Collective Participation: Usage Patterns,Political Efficacy,and Political Participation in Social Networking Sites

This study assesses differences in use of social networking sites (SNSs) and relates them to different patterns of political participation, media use motivations, and political efficacy. Based on a Web survey of 1,230 South Korean voters, it finds that informational uses of SNSs are positively associated with expressive participation both online and offline, but not with collective participation. The use of SNSs for social interaction purposes was associated only with online expressive participation. Recreational uses had a negative or insignificant relationship with expressive and collective participation. Political efficacy moderated the impact of social interaction uses of SNSs on expressive participation both online and offline. The findings suggest that the political impact of SNSs is mostly limited to expressive participation and dependent upon users' motivations.     

中国初创期电视新闻形态及其开创的传统

历史的演进总要指向特定鹄的,初创期(1958-1965年)的中国电视新闻固然有着形式简陋、内容单一等问题,却在理念和实践上对后世的发展产生了深远的影响。中国电视新闻的传统并未因"文革"而出现断裂,早期电视新闻在对《新闻简报》的播放和大量实况转播实践中形成的关于电视新闻的纪实与美学的风格与功能的种种理解,均对中国电视新闻的后续发展产生深远的影响。对早期电视新闻形态的深入考察,也有助于我们对中国电视新闻后来的变迁历程、当下的发展路径及其产生的社会影响有更加深入的理解。     

Investigating the synergy of critical thinking and creative thinking in the course of integrated activity in Taiwan

The relationship lying between critical thinking and creative thinking is opposite or complementary, results of previous relevant researches have not yet concluded. However, most of researches put the effort to compare the respective effect of the thinking methods, either the teaching of creative thinking or that of critical thinking. Less of them showed the interest to investigate the combined effect of these two thinking skills teaching, especially its synergy. Therefore, present study aimed to discuss the synergy of critical thinking and creative thinking, and investigated the joined effect of these two methods of thinking in the courses of ‘Integrated Activity courses’. Not only the separate influence but also the synergy would be our interests. Moreover, the outcome would also be compared with the learning result of single creative thinking skill teaching. Participants were 147 male students and 118 female students of ninth grade from 8 intact classes in a public middle school in Taiwan, the number of total participants were 265. Experimental design was ‘nonequivalent control group pretest/post-test quasi-experimental design’. Participants were assigned into three groups, three intact classes for creative thinking teaching group (EG1), three intact classes for ‘critical thinking and creative thinking combined teaching group (EG2)’ and two intact classes for regular teaching method group (watching video, control group). All participants took the assessment ‘The New Creative-Thinking Testing’ and ‘The Critical-Thinking Testing, Level 1’ after receiving the courses as post-test. Data were analysed statistically by one-way ANCOVA. The results showed that:

1. Regards to the performance in Integrated Activity courses, no significant difference was found among students in EG1 and those in EG2. However, the students in both experimental groups got higher scores than those in control group did.

2. As for the ability of critical thinking, students in EG2 got higher score than those in EG1 and CG did, but no difference was found among the students in EG1 and those in CG.

3. In respect of originality, students in EG2 got higher score than those in EG1 did, the influence of critical thinking was significant.

Theoretical and possible applications of the results were also discussed. Present study not only manifests the correlation between creative thinking and critical thinking, but also provides the empirical data for synergy in actual pedagogical situations.

图书馆教育研究在中国的双向学科化走势

图书馆教育研究伴随着图书馆事业、图书馆学的发展而兴盛起来.由于对象范围的逐渐分化,图书馆教育研究近年来在中国出现了双向学科化走势,初步形成图书馆教育学的两门主干分支学科—图书馆专业教育学和图书馆社会教育学.为了更好地推进这两门学科的可持续发展,当前需要对两者做整体协同性思考,包括把握两门学科的亲缘关系、强化两门学科的始端开发、加固两门学科的共同基础.
