“越位”报道：媒体的另一种“施暴”
“越位”报道 媒体 另一种“施暴”
2009/9/10
大众传媒因掌握着话语权而成为现代社会重要的权力中心之一，也就是所谓的“第四权力”。我们知道，一个健康运转的社会，任何权力都应有其边界，受到一定的制约。然而，当下中国的传媒业在迅猛发展的同时，新闻报道中经常出现的“越位”现象不能不引起媒体从业人员的警惕和反思。
遵循健康传播规律,突显广播媒体优势
健康传播 规律 广播媒体 优势
2009/9/10
大众传媒在健康传播中起到非常重要的作用。特别是在中国，广播作为广覆盖的媒体，在对农村边远地区的国民进行有效健康教育的作用不可替代。如何让广播更好地发挥传播健康知识的作用？作为《走进农村妇女健康学堂》的主要作者之一，我在选题策划、节目设计等环节重点考虑了以下关键因素：1、充分考虑健康传播的规律；2、充分考虑节目选题的现实性和针对性；3、充分考虑广播媒体的特点；4、充分考虑节目效果与当地技术条件的可行...
在电视传媒业中，素有“新闻立台”之理论，纵观全国，无论中央台、地方台还是城市台，甚至区县级台几乎都有几个或一个在一定区域内家喻户晓的新闻栏目，如《新闻联播》、《焦点访谈》、《新闻调查》、《本周》、《南京零距离》、《直播南京》、《今晚800》、《新闻夜班车》、《百姓关注》等等，都是在立台、强台中竖起过一方大旗的名牌栏目。这些品牌栏目虽然名称各不相同、定位互有差异，或时政、或民生，但溯其创办思路与宗旨...
城市台的冬天——《中国城市电视台发展报告》序言
城市电视台 冬天 发展报告 序言
2009/9/10
城市台的冬天已经来临。我作出这个判断，不是危言耸听，而是基于本人对最近几年城市电视台现状全面而认真地考察后，作出的判断。本人的想法是利用占有的资料，对城市电视台的发展情况做一个总体梳理、描述与分析，提出自己对城市台的一些认识，以引起城市台电视人的注意，同时也为研究城市台的学界提供一些来自一线的参考资料。
