Efficacy Foundations for Risk Communication: How People Think About Reducing the Risks of Climate Change

Believing action to reduce the risks of climate change is both possible (self‐efficacy) and effective (response efficacy) is essential to motivate and sustain risk mitigation efforts, according to current risk communication theory. Although the public recognizes the dangers of climate change, and is deluged with lists of possible mitigative actions, little is known about public efficacy beliefs in the context of climate change. Prior efficacy studies rely on conflicting constructs and measures of efficacy, and links between efficacy and risk management actions are muddled. As a result, much remains to learn about how laypersons think about the ease and effectiveness of potential mitigative actions. To bring clarity and inform risk communication and management efforts, we investigate how people think about efficacy in the context of climate change risk management by analyzing unprompted and prompted beliefs from two national surveys (N = 405, N = 1,820). In general, respondents distinguish little between effective and ineffective climate strategies. While many respondents appreciate that reducing fossil fuel use is an effective risk mitigation strategy, overall assessments reflect persistent misconceptions about climate change causes, and uncertainties about the effectiveness of risk mitigation strategies. Our findings suggest targeting climate change risk communication and management strategies to (1) address gaps in people's existing mental models of climate action, (2) leverage existing public understanding of both potentially effective mitigation strategies and the collective action dilemma at the heart of climate change action, and (3) take into account ideologically driven reactions to behavior change and government action framed as climate action.     

People with disability and new disaster communications: access and the social media mash-up

This article explores how a lack of access to increasingly complex and overlapping digital communications platforms in times of disaster for people with disabilities has the potential to make already life-threatening situations considerably more dangerous. As we are increasingly coming to rely on a social media mash-up of digital platforms to assist in communications during disaster situations, the issue of accessibility for people with disabilities is as dire as if it was high ground during a tsunami or transport during a typhoon. The contemporary social media environment is characterised by a complex and overlapping network of complementary platforms, populated by user-generated content, where people communicate and exchange ideas. In this environment, YouTube videos are posted to Facebook and embedded in blogs, and Twitter is used to link to these other sites and is itself embedded in other platforms. These networks are increasingly supplementing and supplanting more traditional communication platforms, such as the television and radio, particularly in times of disaster. The concern of this paper is that the elements from which this mash-up of communications channels is made are not always accessible to people with disabilities. This evolving network of social media-based communication exposes the limits of existing Internet-based universal design.     

大众传播中的“国家教师”媒介形象分析

运用传播学内容分析法，以中央媒体对获得"全国教书育人楷模"和"最美教师"荣誉称号的"国家教师"相关报道为研究对象，从外在和内在两个方面对大众传播的"国家教师"媒介形象进行分析。外在形象包括教师性别、年龄、教龄、外表、场景以及任教的学校类别、区域、学科专业等方面，内在形象包括职业精神、职业知识和职业能力等方面。研究发现，大众媒体对"国家教师"形象的刻画和宣传符合社会公众认知教师职业的基本逻辑，起到了传递教师精神、端正教师形象、唤起社会尊重教师的功效，但也存在城乡教师形象传播刻板化以及教师普通人形象展现不充分等问题，可在后续的传播中对"国家教师"形象的价值倾向进行适当调整。     

Maternal and paternal reactions to child sadness predict children's psychosocial outcomes: A family‐centered approach

Parents' reactions to children's emotions shape their psychosocial outcomes. Extant research on emotion socialization primarily uses variable‐centered approaches. This study explores family patterns of maternal and paternal responses to children's sadness in relation to psychosocial outcomes in middle childhood. Fifty‐one families with 8‐ to 12‐year‐old children participated. Mothers and fathers reported their reactions to children's sadness and children's social competence and psychological adjustment. Cluster analyses revealed three family patterns: Supportive (high supportive and low non‐supportive reactions from both parents), Not Supportive (low supportive reactions from both parents), and Father Dominant (high paternal supportive and non‐supportive reactions, low maternal supportive and non‐supportive reactions). Supportive families had children with higher social competence and more internalizing symptoms whereas Father Dominant families had children with lower social competence and fewer internalizing symptoms. Not Supportive families had children with average social competence and fewer internalizing symptoms. Findings are discussed in relation to the “divergence model” which proposes that a diverse range of parental responses to children's sadness, rather than a uniformly supportive approach, may facilitate children's psychosocial adjustment.     

微信时代风险信息的传播与感知——以山东“问题”疫苗事件为例

目前,以手机终端为依托的微信传播技术不仅给社会传播方式带来了前所未有的改变,而且给社会风险信息的传播获取以及公众对风险的感知与判断,甚至政府的风险决策与治理方式都带来了巨大的挑战.鉴于此,选取了比较典型的案例——山东“问题”疫苗事件作为探讨对象,结合相应的统计资料,深入分析了在此案例中微信传播呈现出的显著特征,即传播内容庞杂未见明显的“沉默螺旋”的显现,传播态度多元化但偏于激动,传播迅速集中但议题缺乏持续的关注.研究认为,正由于这样的传播特征加之疫苗风险本身的特征与个体的偏颇性解读,使公众对“问题”疫苗事件产生了强烈的风险感知,并在一定程度上造成了疫苗的污名化结果.因此建议微信时代一定要警惕媒介化的风险,风险沟通要在同理心的基础上进行,要引导公众对风险议题进行持续理性的关注等.

信息时代国际传播的控制:从管制到治理

以数字化和网络化为标志的信息技术革命使国际传播环境发生了很大变化,也使得民族国家的传播管制面临挑战,而把治理的理念引入国际传播领域,有助于探索在信息技术革命条件下国际传播管理的新途径。国际传播控制从管制到治理,实际是对国际传播秩序的改造和完善:从参与的主体看,承担维持国际传播秩序任务的既有政府组织,也有非政府组织、跨国公司、私人企业、利益集团和社会运动团体等;从治理内容看,于侧重意识形态之外,又加入了保护民族文化、维护本国经济利益等新内容;从范围上说,它已不限于领土范围之内,而是积极参与国际传播领域的合作,以建立有利于完成国内传播控制目的的国际传播环境。     

中国网上聊天室中英语语言特征

中国网上英语聊天室中的英语与英语国家聊天室中的英语相比较 ,在某些方面 ,如缩写的使用、句首字母少用大写、句尾少标点等有一些共同的特征。但由于受本族语的影响 ,中国人网上聊天的语言有其独到之处。中国人用英语聊天的目的主要是为了练习语言 ,使英语语言的交际功能减弱。受语言水平所限 ,中国聊天者的会话语言更接近书面语体 ,聊天的内容狭窄且缺乏连续性。网上聊天 ,作为一种新的语言交际方式 ,为英语学习者们提供了另一种学习途径 ,在练习快速英语思维及表达方面有着积极作用
