John Fisk once classified communication studies into two camps: the “process school” that sees communication as the transmission of messages and the “semiotic school” that sees communication as the “production and exchange of meanings”, and the latter is the path that Fiske’s own research has always run through. In the context of today’s new media with information explosion and value loss, the significance of “meaning theory” is more prominent. Following Fiske’s idea of focusing on “meaning exchange”, combined with the history of the introduction of the term “communication” in China, this paper re-examines the basic concept of “communication”, and on this basis, sorts out the three levels of communication meaning realization the inherent logical relationship among “media, information and symbols”.
The American news industry is arguably run by its laws of news values and business logic.This paper aims to explore the principle of news objectivity in American commercial newspapers from a theoretical perspective of transaction costs. Previous studies on professional ideology have overlooked its origin that rooted in American commercial environment and developed along with commercial newspapers. This study indicates that the principle of objectivity is not only an editorial policy for commercial newspapers, but also a business strategy and governance mechanism, which reduces both the internal and external transaction costs of news production and improves the use of resources. Furthermore, news efficiency can increase the profit margin, and this is the core reason for the emergence and maintenance of the principle of news objectivity, but also an important reason for today’s challenges when information customization has been realized.
Among the major social media platforms, Twitter ranks at the top with its whopping 436million users and its 211 million monthly active users, and 48 million of these accounts are social bots. With the increase in the number of social bots on Twitter, the structure of interaction and social contagion subjects in social media has changed, so what kind of interaction characteristics do social media users present? What are the contagion strategies of social bots? What are the social contagion mechanisms of social bots? These are three questions that arise from the current engagement of social bots. Based on this, taking the 2022 Beijing Winter Olympic Games as an example, we use Python to crawl relevant tweets on Twitter, and through visual analysis of social bot accounts and tweets, we can find that social bots construct dynamic social network structures according to specific purposes and for different types of contagion, to achieve their information diffusion and social contagion.
本文采用自动化内容分析方法,对2022年全球新闻学研究的前沿成果进行了全面而细致的综述,尝试据此归纳新闻学学术发展当下的重点议题和演进方向.基于LDA主题模型,在对样本中723篇学术论文进行主题聚类和文本挖掘的基础上,本文发现:应对信息失序是引领当下全球新闻学研究的核心主题,新闻学研究的总体议程向本学科基本观念回归;在对批判理论资源的广泛吸纳中,新闻学研究呈现出更加鲜明的反思性和规范理论自觉,这为未来新闻学学术发展提供了基础动力;数字新闻学呈现出更精细的颗粒度和更丰富的话语层次,学界不断在知识生产和价值确信两个维度上探索对这一新范式进行体系化的有效路径.
俄乌冲突是深度伪造首次被全面运用于战争场景中,两条对俄乌双方最高领导人的深度伪造视频是标志性案例.分析发现,两条视频制造认知的罗生门效应特征显著,在发布时间点和主题上具有明显针对性,内容上相互博弈;在Twitter平台上,两条深度伪造引发了网民"真与假"的认知困惑并带来不同情绪,进而影响了网民对后续相关内容的判断;两条深度伪造视频得到较大范围的海外机构媒体关注,并表达了对深度伪造的忧虑与警惕.本文进一步分析了数字罗生门的含义,并提出了从信任角度予以探讨的思路.
