Social Media References in Newspapers

Social media are increasingly being used as sources in mainstream news coverage. Yet, while the research so far has focused mainly on the use of social media in particular situations, such as breaking news coverage, during crisis news events or in times of elections, little attention is paid to journalists' routine, day-to-day monitoring of social media platforms. The aim of this study is to examine the use and selection of social media as sources in routine newspaper coverage. First, it presents a quantitative overview of all the articles published between January 2006 and December 2013 in the print editions of two Flemish (north Belgian) quality newspapers, De Standaard and De Morgen, that explicitly refer to Facebook, Twitter or YouTube. Next, a content analysis is conducted of a sample of newspaper articles published in 2013 that explicitly mention Facebook, Twitter or YouTube as sources of information. The goal of this content analysis is to examine the different appearances and functions of social media references in the news. The study thus provides a first insight into Belgian newspaper journalists' regular sourcing routines in relation to social media.     

Metacoverage and Mediatization in US Presidential Elections

This article develops a theoretical model consisting of three mechanisms that link metacoverage, a type of election campaign news, to mediatization, a meta-process in which media organizations influence politics. The mechanisms hinge on the point that metacoverage—consisting of both topics and frames—constitutes a rich set of process-oriented cues that influence how campaign organizations adjust to the media logic in the course of performing functions associated with the office-seeking political campaign logic. A case study of 2012 US presidential election news was conducted to illustrate how metacoverage influences campaign strategies.     

Passive Accomplice or Active Disruptor

Mediatization of politics in the institutional perspective is commonly taken to refer to the interactions between political actors and media actors, where the first become increasingly governed by media logic and the latter become increasingly independent from other institutions. Even though we could picture the relations between the different constituents as a triangle with audience, media and political actors as equally important corners, the institutionalist perspective does not give equal attention to the audience as actor in the process. In this article, I ask to what extent audience participation in news production affects our understanding of the process of mediatization of politics. I discuss both how audience participation can be seen as a challenge to media's role in politics (challenging the current conceptualization of mediatization of politics) as well as how the theory of mediatization can be seen to be confirmed by currently dominant audience participation practices. In the first understanding, we can argue that audience participation challenges independence of institutional media actors (to give more power to both audiences and politicians). In the latter understanding, audience participation can be seen to be governed by the same commercial interests as other media production and in addition that both mainstream and alternative media are subject to search engine logic. This article then calls for a critical examination of our understanding of mediatization of politics to do justice to the multiplicity of logics informing media practices, the multiplicity of actors producing news and, crucially, the interaction between those logics and actors.     

Media Logic and Political Logic Online and Offline

One aspect of the mediatization of politics is the idea that political actors adapt to the communication logic of news media to gain, for example, news media attention. Currently, this process may be influenced by the diffusion of the internet as a political communication channel, especially because online communication provides a new opportunity for political actors to communicate directly with citizens. Thus far, the adaptation to media logic by political parties has mainly been examined in the context of election campaigns. In order to transfer these findings to regular political communication, this study compares the use of media logic in the mass media and in direct political communication channels online and offline about the United Nations Climate Change Conferences 2011 and 2012. A quantitative content analysis of the conference protocols (input) and the presentation of the conference results in the seven most frequently used German offline news outlets (print and TV) and their online counterparts, as well as political offline and online communication channels like parliamentary speeches and websites of the six parties represented in the German parliament (output), was conducted. Results show that in the context of regular political communication, political actors seem to follow media logic to a lesser extent than in the context of election campaigns. Thus far, the influence of online communication on the mediatization of politics seems to be rather marginal. The causes and consequences of these findings are discussed.     

社交媒体环境下突发事件严重性评估和预警机制研究

[目的/意义]突发事件的快速蔓延与恶化使得应急管理部门需实时评估突发事件的严重性,并建立科学的预警机制。微博等社交媒体平台为突发事件的实时研判提供了丰富的线索。[方法/过程]从网民作用、网媒作用、事态扩散、态度倾向、网民情感等维度构建突发事件严重性评估指标,提出突发事件严重性指标的影响倾向分析及特征比较方法。以2018年“8?24乐清女孩乘车遇害案”“5?6郑州空姐打车遇害案”“8·27昆山持刀砍人案”和2017年“携程亲子园虐童事件”这4个社会安全事件的1107308条微博数据为例,通过突发事件严重性指标的影响倾向分析,划分突发事件严重性等级,建立突发事件预警机制。[结果/结论]研究结果建立了突发事件的量化分级标准,为政府及时采取应急管理措施提供方法指引与数据支持。     

何因生倦怠,何素调节之？——一项关于社交媒体倦怠的元分析研究

[目的/意义] 针对现有社交媒体倦怠影响因素的探究中存在不一致和差异性的问题,使用定量分析方法对已发表的实证研究文献中的统计结果进行梳理总结和再统计。[方法/过程] 本研究从68篇实证研究文献中共提取出72组224个效应值进行研究,将社交媒体倦怠影响因素归纳为情境和本体两大因素,并提炼出平台类型、文化特征、社交媒体使用程度、用户性别及被试群体5个调节变量。使用元分析定量分析方法,通过异质性检验和次群体检验来探讨不同因素对社交媒体倦怠的影响,并检验调节变量对社交媒体倦怠影响的显著性。[结果/结论] 研究结果表明,情境因素和本体因素均对社交媒体倦怠产生显著的正向影响;两者对社交媒体心理倦怠的影响均强于对社交媒体行为倦怠,而情境因素与社交媒体倦怠之间呈现出更高的相关性。同时,本研究归纳识别的5类调节因素在本体因素与社交媒体倦怠之间具有一定的调节效应,而情境因素与社交媒体倦怠之间的关系仅受到被试群体的调节。
