情理与法理的冲突--关于隐性采访的反思     

向淑君 《廊坊师范学院学报》2004,20(1):97-100,105

在西方新闻界对隐性采访理解和使用趋于理性的同时，隐性采访在中国目前却呈泛滥之势。受众情感上的包容和媒介缺乏自律是其泛滥的主要原因。由此引发了诸多法律和道德上的问题，并危害了新闻事业的健康发展。而在法律范围内有序操作和在技术层面上的规范化是隐性采访规避冲突的必然选择。  相似文献

Global questioners: examining journalists’ aggressiveness at Chinese premiers’ press conferences (1993–2015)*     

Feng Wu  Yang Cheng  Duo Chao 《亚洲交流杂志》2017,27(4):357-377

This paper explores the different levels of aggressiveness in five dimensions exhibited by journalists with diverse global backgrounds at the press conferences of four Chinese premiers. Four attributes of the journalists’ home countries are examined: (1) power distance, (2) press freedom, (3) stage of development, and (4) frequency of questioning opportunities. The results show that journalists from countries with lower power distances tend to be more direct in their question designs than those with higher power distances; journalists with higher levels of press freedom tend to show more initiative, directness, assertiveness, and adversarialness than those with lower levels; journalists from developed countries are more direct, assertive, adversarial, and accountable than their counterparts; frequent questioners are more assertive, adversarial, and accountable than those infrequent. The theoretical and practical implications of journalists’ aggressive behaviors are discussed.  相似文献   

Spotlight and Investigative Journalism: How the Film Reinforces the Essential Role of a Free,Professional Press in a Democracy     

Michele Drohan 《期刊图书馆员》2016,71(3-4):212-220

This article examines key scenes and ideas portrayed in the film Spotlight and discusses related landmark Supreme Court cases as a reaffirmation of the value of a professional, free press in a democratic society. Based on actual events, the movie adaptation follows journalists from the Boston Globe (within an investigate unit with the actual name “Spotlight”) as they reveal one of the biggest scandals of the twenty-first century, the cover up of systematic abuse of children by priests; and go up against one of the most powerful institutions in the world, the Catholic Church. By giving a voice and a platform for the victims, and by meticulously researching the story, the film provides a clear and strong argument for the continued court protection of one of the United States’ founding principles: freedom of the press.  相似文献
