[目的/意义]旨在为治理网络谣言提供实践思路。[方法/过程]以新冠肺炎疫情网络谣言为例,在批评话语分析的理论框架下从描写、理解和阐释三个层面研究网络谣言的语言学形式特征、话语实践和社会实践特征。[结果/结论]突发公共卫生事件网络谣言的形式特征表现在词汇、句法、语篇多个层面。在话语实践方面,公共卫生事件网络谣言的产生与互文性相关,受众的理解和传播与谣言所实施的断言行为、指令行为、承诺行为和表达行为相关。在社会实践方面,公共卫生事件网络谣言的产生动机主要是利益驱动和情绪驱动,多元媒体下的话语权为谣言的产生提供条件,社会认知图式促成谣言的理解和传播。突发公共卫生事件网络谣言的批评话语分析为网络谣言文本的识别、网络谣言行为的治理和人们网络媒介素养的提升提供启示。 相似文献

[研究目的]人们越来越多通过社会化媒体来获取健康信息,但网络健康谣言容易被用户大量转发,网络健康谣言治理需要深入分析受众谣言转发行为机制。[研究方法]该文以S-O-R模式为框架,构建了影响受众转发谣言意愿的模型,并采用实验法予以证明。[研究结论]结果发现恐惧型健康谣言较之期望型健康谣言具有更高传播意愿,焦虑是影响健康谣言转发的中介变量,此外信息涉入度和网络健康素养分别对焦虑感和谣言转发具有调节效应。 相似文献

[研究目的]突发公共事件中强关系社交网络谣言呈现核聚变式快速传播,从认知加工视角探究谣言扩散影响因素与作用路径可以提升对谣言传播机制的理解,进而有效遏制谣言传播。[研究方法]以情景意识理论为基础,使用调查研究法探究证实了突发公共事件中受众会整合环境情境性、信息性和主体性信息并进行匹配与加工,在知觉与理解层次等情景意识作用下形成对谣言的扩散意愿。[研究结论]事件重大性与信息模糊性通过风险感知的完全中介作用正向影响谣言扩散,信息框架性与情绪性通过信任度的部分中介作用正向影响谣言扩散;主体的个体活跃度与群体凝聚力通过信任度的完全中介作用正向影响谣言扩散。 相似文献

【目的/意义】用户接触辟谣信息，并不能等同于用户接受辟谣信息。研究疫情防控背景下影响用户接受政府辟谣信息意愿的主要因素和相关路径，有助于政府精准治理网络谣言。【方法/过程】调查疫情防控背景下的网络用户接受政府辟谣信息的相关心理与行为，以脆弱性理论为基础构建理论模型，运用模糊集定性比较分析法对问卷数据进行影响因素与组态路径分析。【结果/结论】政府辟谣信息接受意愿的影响因素组态可分为三类：社会支持型、社会支持—谣言鉴别能力型、谣言鉴别能力型。动态压力、信息焦虑、社会支持和谣言鉴别能力是影响政府辟谣信息接受意愿的核心因素。【创新/局限】组态分析更加深刻地揭示影响政府辟谣信息接受意愿的不同核心因素的联合影响机制和实现路径。后续研究可比较分析疫情不同时期影响用户辟谣信息接受意愿路径的差异性。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
