An integrated model of parental mediation: the effect of family communication on children's perception of television reality and negative viewing effects

This study proposed and tested an integrated model of parental mediation involving family communication, parental mediation styles, children's perceptions of televised realities and the actual world, and perceptions of the negative effects of television viewing. A total of 348 Korean adolescents participated in a nationwide survey. The findings demonstrated that parental, instructive mediation, in combination with open family communication, increased not only children's perceived disparity between televised realities and the actual world, but also children's perceptions of the potentially negative effects of television. Restrictive parental mediation styles were also found to mediate the role of open family communication on children's perception of negative effects of television. In contrast, co-viewing mediation was not found to directly affect either the children's perceived reality or their perception of negative effects of television viewing.     

主题科学传播的选题与渠道分析 ——以COVID-19疫情情境下我国医学论文传播为例

主题科学传播在选题策略和传播渠道均存在其特点。选取我国新型冠状病毒肺炎学术成果交流平台2020年1月27日至7月19日网络载文作为典型案例,收集单篇论文的阅读量、题目、期刊、作者信息及网页访问量构成,定性分析论文学科属性与传播主题的关联,定量分析全球访问量的国别特征、构成及趋势。高阅读量论文的选题呈现以下3个特点:与中心事件强相关、与关键问题有结合点、研究对象较受关注,单篇阅读量较高的论文类型为论著、指南共识、述评专论。网络传播中以直接访问与外部链接引流为主要渠道,引流来源以自建网络平台、文献数据库、主流搜索产品(如百度学术)为主。随着疫情形势变化及观察时间窗延长,访问量增幅较大的渠道以微信公众平台及社交媒体为主,新增渠道包括不同出版平台资源中心外链及大众新闻媒介。除我国外,访问量较高的国家为美国、巴西、印度、日本、意大利。主题科学传播中传播迅速且较受关注的论文选题兼顾学科关联性及公众关切,传播渠道以网络为主。随着时间推移,即时通讯及社交媒体传播增速较高,更多境外网络访问、出版机构互链及国际学术组织数据库涉入,科学传播的受众角色更加丰富。中文论文的国际推广应注重传统平台及新兴渠道的均衡发力,凭借国际化资源中心及社交媒体平台主动传播。
