随着科学技术的发展和全球化进程的加快,我们已经进入乌尔里希·贝克所提到的“风险社会”.一方面,以社交媒体为主的新媒体为风险信息的传播提供了新的平台;另一方面,在社交媒体盛行的环境下,信息发布的主体、信息数量、信息的敏感性和信息发布的时间都有可能放大风险.此外,社交媒体上关于风险事件的争鸣也会放大风险,而风险的化解则依赖于社交媒体的风险沟通和风险治理. 相似文献

新冠肺炎疫情这一重大突发公共卫生事件发生后,中国政府倡导的集体防疫行动取得了显著的成效。社交媒体作为公众信息获取的主要渠道,在建构风险感知、动员公众参与等方面发挥了重要作用。以往的风险沟通研究多集中探讨个体层面的媒体使用、风险感知与防疫行为,缺乏对社会层面的观照;且多将社交媒体笼统考量,难以提出足够有针对性的沟通方案。有鉴于此,论文通过细分社交媒体、风险感知和防疫行为类型,构建了“心理动机-媒体使用-风险感知-防疫行为”模型,在梳理疫情期间公众社交媒体摇摆使用行为及其内在动因的基础上,检验其对个体与社会层面风险感知和防疫行为的影响。研究发现,监测、社交、回避等动机会促使公众摇摆使用内容导向型社交媒体和用户导向型社交媒体。从作用机制来看,内容导向型社交媒体可直接影响或间接通过风险感知推动个体采取自我保护行为,并且配合集体防疫行动;而用户导向型社交媒体仅可直接作用于集体防疫行动。另外,社会规范在内容导向型社交媒体使用对集体防疫行动的作用路径中发挥了正向调节作用。 相似文献

信息传播环境的改变推动了社会个体信息消费行为的变革。当下,我国媒介环境的改变使社会化媒体成为人们信息消费和人际交往的主要场域。社会化媒体中信息生产者身份的匿名性和网络公共领域的开放性加剧了信息风险等级。受众在表达自我的同时,由于缺乏辨别信息真伪的能力,往往盲目地充当风险信息的二次生产者。风险信息一旦进入以"圈层形态"为主的人际传播环境中,则极易引发葡萄藤效应,进而诱发社会群体性事件。目前,我国正处于社会转型和经济转轨的关键时期,和谐的传播环境有利于社会稳定和个人发展。受众作为信息传播链条中的重要环节,其信息解构能力与传播效果密切相关。因此,需要从媒介素养的研究视角出发,探寻社会化媒体环境下受众应对信息风险的可行性路径。 相似文献

Air pollution is a critical environmental problem that has spurred great public concern in China. This study examines how issue salience, environmental value, risk perception, and affective response influence information seeking, objective knowledge, and policy support related to this issue. The recent release of a controversial environmental documentary on Chinese social media, Under the Dome, also prompted us to explore the impact of exposure to this documentary on Chinese social media users’ information seeking and policy support related to air pollution. Results showed that risk perception and negative affect influenced information seeking and policy support both directly and indirectly. Also, exposure to the documentary moderated the effects of key variables on information seeking and policy support. However, contrary to our expectations, no significant relationship was found between information seeking and objective knowledge. Theoretical and practical implications of these findings were discussed. 相似文献

Government social media has been integrated as part of the government administrative tools to improve public service and promote public goals. However, the current government information literature is limited to understanding government social media adoption and its purpose for political marketing. The present study seeks to understand the role of government social media in promoting government digital initiatives (i.e., government-backed digital currency). The study validated the inter-relationships between government social media effort, privacy concerns, trust in technology, reachability, and citizens' participation in government-initiated digital innovations. A total of 505 responses from Chinese citizens were collected through an online self-administered questionnaire survey, and the data was submitted to a two-stage Partial Least Squares Structural Equation Modelling-Artificial Neural Network analysis. The analytic results revealed that privacy concerns, trust in technology, and reachability positively influence digital participation. In addition, the information quality and perception of trust in government social media have significant positive influences on government social media engagement. The study provides strategic practical suggestions to government agencies in effectively utilizing social media as a communication platform to foster citizens' participation in government's digital initiatives. 相似文献

The sustainability of public health practices requires collaboration between the government and its citizens. On the government's side, social media can provide a conduit for communicating health risk information in an effective and timely fashion, while also engaging citizens in informed decision-making. On the citizen's side, information communication technology (ICT)-based practices cannot function unless citizens recognize and act on their responsibility to actively engage with government social media platforms. Despite an increasing interest in understanding the adoption of ICT practices and e-government services for health risk communication, there remains a crucial need for a comprehensive framework to explain which factors determine citizen use of digital government resources. The purpose of this study is to investigate how to increase government accountability for motivating citizens to engage in ICT-based health risk communication, thereby attaining sustainable public health practices through collaborative governance.By integrating trust and health risk information into the e-government adoption model (GAM), this research examines factors that influence citizens' likelihood of using government social media resources. Survey data from 700 Korean citizens were analyzed using structural equation modeling. The results indicated that individuals with higher social media competency are more likely to (a) seek risk information through social media and (b) perceive the government's social media sites as easy to use. Consistent with the GAM, intentions to use the government's social media sites for information and interactions appear to increase as citizens perceive more value in using them regarding information quality, ease of use, functional benefit, and security. Furthermore, perceived trust in the government's social media resources appears to function as a mediator of this process. Initial trust in the government is an important determinant of perceptions of its digital resources. Citizens who trust the government tend to evaluate new initiatives positively and are more likely to accept and make use of them.The results of this study can inform policy design and implementation by elucidating the mechanisms that determine citizens' adoption and usage of digital government services. Theoretically, this work expands the GAM to include health risk communication and adds empirical evidence to the small yet growing body of knowledge of e-government initiatives. These findings also highlight the importance of public trust in the government, as this encourages citizens to seek health risk information and assistance from the government. Overall, the data and model generated in this investigation represent an important step toward the successful and sustainable modernization of public services. 相似文献

Objective
The objective of this literature review was to summarise current research regarding how consumers seek health‐related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers’ information‐seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media.Methods
The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full‐text documents.Conclusion
Between 2011 and 2016, twenty‐one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers’ information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer‐to‐peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement. 相似文献15.

The internet and social media sites are used extensively by violent extremist actors, providing new areas of inquiry for journalists reporting violent extremism. Based on 26 in-depth interviews with Norwegian media professionals, the present article describes how journalists monitor, assess, and make use of online information in investigative reporting of violent extremist groups in today’s networked media environment, characterized by complex interaction patterns, a plurality of voices, and blurred boundaries between private and public communication. While existing research on journalists’ use of social media as a source has tended to emphasize breaking news, the present article focuses on longer-term investigative efforts of journalists. The article gives insights into journalistic investigative practices in the networked media environment, in general, and in reporting violent extremism, in particular. 相似文献

Adopting the Orientation–Stimuli–Reasoning–Orientation–Response (O–S–R–O–R) model of political communication effects, this study examines the mediating roles of online/offline political discussion and political trust on the relationship between social media information seeking and online/offline political participation in China and Hong Kong. Findings through structural equation modeling showed that the relationship between information seeking and online participation was mediated by online discussion for both samples. Moreover, the relationship between information seeking and offline participation was mediated by offline discussion, and offline discussion mediated the relationship between information seeking and online participation. Political trust did not mediate any of the relationships in China and Hong Kong and all significant paths involving political trust were negative. Implications of the findings for youth political participation in China and Hong Kong are discussed. 相似文献

The topic of childhood vaccinations has received much news media attention recently, prompting scholars to examine how the public has responded. In light of this news, and the deep divide that seems to exist between parents who support childhood vaccinations and those who do not, this study examines how and why individuals may involve themselves in communication about vaccinations, particularly on social media or in other online environments. Focusing on the concept of communicative action and drawing from spiral of silence and other research, a survey of mothers (N = 455) found that those who do not support childhood vaccinations are more likely to engage in communication about the issue, including information seeking, attending, forefending, permitting, forwarding, and sharing. In addition, issue importance and affective and cognitive involvement help drive communicative action regarding childhood vaccinations, which could affect public opinion or public perceptions of the issue. Theoretical and practical implications are discussed. 相似文献

This is a multiple methods study that highlights the tension between awareness- and behavioral-based campaign successes, particularly when communicating using social media and pop-culture-referencing humor. To illustrate, it examines the Centers for Disease Control and Prevention's (CDC) “zombie apocalypse” all-disaster-preparedness campaign. An interview with a CDC campaign manager, campaign document analysis, and a 2 (information form: social vs. traditional media) × 2 (message strategy: humorous vs. non-humorous) experiment uncovers benefits and pitfalls of using social media and humorous messaging for risk communication. Findings show social media can quickly spread information to new publics for minimal costs; however, experiment participants who received the humorous (i.e., zombie) risk message reported significantly weaker intentions to take protective actions in comparison to those who received the traditional, non-humorous risk message. 相似文献

When Rush Limbaugh made his now famous remarks about Sandra Fluke's Congressional testimony he set off a social media firestorm. The ensuing backlash cost Limbaugh many prominent advertisers and damaged his public image. In this study, we examine the characteristics that motivated some to engage in the social media conversation while others remained on the sidelines. We find that political information efficacy, or confidence that one has the knowledge and skills necessary to participate, dictate political engagement online. We discuss the implications of this finding for radio, communication and media scholars, and healthy democratic deliberation among young Americans. 相似文献
