The dissemination of relevant information on wildlife utilization and its connection with the illegal trade in wildlife

We analyzed the generation and dissemination of relevant information on wildlife utilization based on the African bush elephant(Loxodonta africana Blumenbach.),the tiger(Panthera tigris L.)and the totoaba,a species of marine fish,(Totoaba macdonaldi Gilbert)as examples,whose populations are more threatened by the illegal wildlife trade.We compared the illegal trade in wildlife with related information in order to find possible associations,searched for relevant information on major international websites to summarize similarities in information production and dissemination,and used a"Zhiwei"dissemination analysis platform to analyze the dissemination of information circulated at Microblog.The results show that the most infuential information related to the trade in wildlife is mainly generated from news media websites and new selfmedia platforms,usually from non-governmental organizations concerned with wildlife protection.The main factors that affect the depth and breadth of disseminating relevant information on wildlife utilization include the participation of relatively infuential opinion leaders,the verification ratio of forwarding users,the number of followers,and affective identification.Misleading information can stimulate and promote poaching and smuggling,regardless of their real market demand or their products.Therefore,all links in the course of information dissemination should be carefully examined in order to purify the information environment and reduce adverse effects of misleading information on wildlife protection.

Pre-warning information dissemination models of different media under emergencies

Pre-warning plays an important role in emergency handling, especially in urban areas with high population density like Beijing. Knowing the information dissemination mechanisms clearly could help us reduce losses and ensure the safety of human beings during emergencies. In this paper, we propose the models of pre-warning information dissemination via five classical media based on actual pre-warning issue processes, including television, radio, short message service (SMS), electronic screens, and online social networks. The population coverage ability and dissemination efficiency at different issue time of these five issue channels are analyzed by simulation methods, and their advantages and disadvantages are compared by radar graphs. Results show that SMS is the most appropriate way to issue long-term pre-warning for its large population coverage, but it is not suitable for issuing urgent warnings to large population because of the limitation of telecom company's issue ability. TV shows the best performance to combine the dissemination speed and range, and the performance of radio and electronic screens are not as satisfactory as the others. In addition, online social networks might become one of the most promising communication method for its potential in further diffusion. These models and results could help us make pre-warning issue plans and provide guidance for future construction of information diffusion systems, thus reducing injuries, deaths, and other losses under different emergencies.

Research on Meteorological Information Transmission Mechanism in the Age of All Media

This paper takes the Fujian Meteorological Service Center as the research objective, and uses the methods of departmental data sharing and network search to study the dissemination mechanism of meteorological information in the whole media era. The result shows that it is of great significance to actively adapt to the characteristics of information dissemination in the all-media era, establish and improve meteorological information service rules and supervision mechanisms, actively explore strong measures to strengthen the monitoring of meteorological services, promptly release authoritative voices, curb the breeding of rumors, regulate the propagation path, and conduct meteorological information dissemination assessment. Finally, this paper proposes the construction of meteorological information dissemination mechanism from five aspects: service quality assessment, introduction of enterprise information filing and credit management system, establishment of authoritative meteorological information sharing channels, formulation of emergency response plans, and vigorous promotion of meteorological popularization. The mechanism provides a theoretical reference for the meteorological department to better adapt to the all-media context and to carry out scientific and effective media-based public opinion information risk management.

A study on predicting crisis information dissemination in epidemic-level public health events

Crisis information dissemination plays a key role in the development of emergency responses to epidemic-level public health events.Therefore,clarifying the causes of crisis information dissemination and making accurate predictions to effectively control such situations have attracted extensive attention.Based on media richness theory and persuasion theory,this study constructs an index system of crisis information dissemination impact factors from two aspects:the crisis information publisher and the published crisis information content.A multi-layer perceptron is used to analyze the weight of the index system,and the prediction is transformed into a pattern classification problem to test crisis information dissemination.In this study,COVID-19 is considered a representative event.An experiment is conducted to predict the crisis information dissemination of COVID-19 in two megacities.Data related to COVID-19 from these two megacities are acquired from the well-known Chinese social media platform Weibo.The experimental results show that not only the identity but also the social influence of the information publisher has a significant impact on crisis information dissemination in epidemic-level public health events.Furthermore,the proposed model achieves more than 95%test accuracy,precision rate,recall value and f1-score in the prediction task.The study provides decision-making support for government departments and a guide for correctly disseminating crisis information and public opinion during future epidemic-level public health events.

情感分歧对社交媒体中信息再传播的影响——以微博为例

[研究目的]社交媒体中信息的再传播是目前主流传播方式之一,研究情感特征对社交媒体中信息再传播的作用,揭示情感信息影响社交媒体中信息再传播的机制,对于科学引导网络舆论、维持健康网络环境具有重要意义。[研究方法]基于认知失调理论,引入情感分歧特征进行情感分析,以社交媒体中帖子的转发数与评论数作为信息再传播效果的衡量指标,构建了情感分歧与情感倾向影响信息再传播的理论模型,并使用微博平台上的数据,对模型进行验证。[研究结论]通过对回归模型结果分析,情感分歧能够显著正向影响社交媒体信息再传播,促进帖子的转发与评论;正面情感倾向性能够显著促进帖子的转发效果,对帖子的评论数影响效果并不显著;帖子内容的情感倾向性能够调节帖子内容中的情感分歧对帖子转发的影响,而评论情感倾向能够调节评论内容中的情感分歧对帖子评论数的影响。

短视频平台公共政策传播的信息框架效应——基于“双减”政策的视频内容分析与实验

[目的/意义]短视频作为新兴的互联网信息表达方式,已逐渐成为政策传播的重要工具。探索短视频平台在公共政策信息传播中的效力以及受众采纳意愿,有助于提升公共政策传播效果。[研究设计/方法]以“双减”政策为例,根据框架效应理论和信息采纳理论,通过内容分析法归纳总结短视频平台中“双减”政策信息框架的组织方式,同时分析不同政策信息框架对传播效果的影响;此外,采用在线控制实验法验证了不同政策信息框架对受众采纳意愿的影响。[结论/发现]在短视频平台中有近四成的信息使用了目标框架,其中损失框架居多,多数采用集体主义视角和非叙事陈述方式;目标框架、文化框架、叙事框架对受众的评论、转发、点赞意愿并未产生显著影响;双减政策信息中,损失、收益框架,集体、个人主义价值观以及叙事和非叙事要素都能增强受众的采纳意愿,并且目标框架与文化框架之间存在交互效应。[创新/价值]研究结论对于政策宣传部门及相关政府机构优化政策传播策略,提高传播效果具有启示作用。

网络暴力刑法规制的信息传播犯罪模式

网络暴力作为一种“社交网络恐怖主义”,已严重污染网络空间的生态环境。刑法领域对网络暴力的规制,存在着网络话语替代规范话语、无形暴力等价有形暴力的趋势,这一趋势有自相矛盾和泛化因果关系的问题。从认识论、传播学和实践论等视角,甄别网络暴力的(人身)攻击性不法信息肆意传播的本质,可为网络话语寻找规范依据。基于此,可以验证专设“网络暴力罪”的治理模式并不妥当。在既有刑法体系下,应当塑造网络暴力的信息传播犯罪规制模式,分别从网络暴力的信息制作者、信息传播者和传播辅助者等视角,贯彻网络暴力信息传播犯罪规制模式的实施方案。对于网络暴力行为的入罪标准,不宜坚守纯粹形式化的传播次数标准,应当坚守形式与实质并存的法益侵害程度标准,并以实质的“可控性”标准作为划定法益侵害程度的标尺。

NFT数字作品交易行为的“发行属性”与适用规则

NFT数字作品交易方兴未艾,但侵权问题频现,亟需合理的规制路径。NFT技术促进数字作品交易客体特定化并产生准物权变动的效果,使NFT数字作品区别于一般数字作品与传统作品,为发行权扩张提供了技术性支撑。但发行权的扩张尚面临诸多困境,包括“有形载体”要件的阻碍、“所有权转移要件”标准不明、发行权与信息网络传播权在数字环境中存在重叠等。基于此,应当厘清数字环境中发行权与信息网络传播权的关系;细化NFT数字作品交易领域的发行权适用标准,完成从“有形载体”到“作品与载体相对应”的转变,明确“出售”及“所有权转移”的认定;以“转让+删除”技术及征收版权转售费作为辅助手段,完成发行权在NFT数字作品交易中的嬗变与适用。

基于fsQCA的事件信息跨平台传播效果影响因素研究

[目的/意义]当前,网络媒体已经成为信息传播的主要渠道。探究事件信息跨平台传播的影响因素对于增强信息传播效果具有重要意义。[方法/过程]文章基于多案例研究提炼出一般性事件的信息跨平台传播模式,旨在为信息发布者优化传播策略、有效应对网络舆情提供理论参考。结合场域理论和假设性新闻图式结构提出事件信息场域,基于注意力分配理论、两级传播理论等构建事件信息跨平台传播影响因素框架,并运用fsQCA方法对30个案例在高覆盖平台数、低覆盖平台数、高传播热度和低传播热度4个结果下的条件组态进行了分析。[结果/结论]发现环境热度是事件信息跨平台传播的关键驱动因素,意见领袖在拓宽传播广度和提高传播热度中发挥重要作用,较少的情节反转有助于控制事件信息跨平台传播效果。非环境热度(反向测量)和非情节反转是低覆盖平台数和低传播热度的必要条件。对于正面事件的信息传播可从避开重大热点事件、营造复杂情节设置、细化传播策略等方面加以改善,对于负面事件可从提高环境热度、实施缓和的情感动员策略、及时回应避免谣言等方面进行干预,避免造成舆情和不良社会影响。

群体信息传播效能维度及其激活路径

在人人是传播者的群体传播时代,传播模式已从个体扩展模式转向到群体蔓延模式。有效激活群体信息传播效能是把握新时代信息传播规律的关键。从群体信息传播效能的主体、本体、载体和受体等四个维度的作用机理来看,群体信息传播的效能激活路径为如下四种:其一,基于主体维的群体领袖、本体维的群体议题、载体维的群体平台以及受体维的群体感染等角色定位;其二,坚持主体维的个别性群体效能公共化、本体维的公共效能最大化、载体维的局部效能利益化、受体维的转换效能通俗化等价值导向;其三,以主体维的肇始催化、本体维的认知引领、载体维的数量拓展、受体维的扩散施效等行为目标;其四,建构主体维的中心、扩张本体维的认同、分享载体维的便利度、激励受体维的勤勉度等关注焦点,使传播效能得到合理科学的引导。
