广播 基层治理 媒介实践
2024/1/3
加强基层建设与创新社会治理，是当代中国社会建设的两个重要议题。2021年4月28日，《中共中央国务院关于加强基层治理体系和治理能力现代化建设的意见》提出，“基层治理是国家治理的基石，统筹推进乡镇（街道）和城乡社区治理，是实现国家治理体系和治理能力现代化的基础工程”；党的二十大报告提出，要“健全共建共治共享的社会治理制度，提升社会治理效能”。基层，是国家治理体系在地方层面的基础结构；基层治理，是实现...
赵云泽等：“网感”：网络时代下媒介内容价值要素分析
网络时代 媒介内容 价值要素分析 网感
2024/1/2
“网感”正在成为网络时代内容生产与传播的价值判断重要指标，新闻文本本身的边界也在逐渐模糊，这是同网感标准相互建构的结果。网感判断标准的形成实质上体现了网络时代下内容价值要素的变迁的结果。本文系统梳理网感的构成要素及其社会影响，发现网感由心理接近性、趣味性、可参与性、有用性和高情绪唤起性、显著性、叙事语言年轻化、临场感、碎片化和奇异性等要素构成。这些要素也是动态变化的，会随着媒介技术与社会的发展而不...
