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.     

Efficacy,Action, and Support for Reducing Climate Change Risks

A growing body of research demonstrates that 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. Despite this potentially critical role of efficacy beliefs, measures and their use vary wildly in climate change risk perception and communication research, making it hard to compare and learn from efficacy studies. To address this problem and advance our understanding of efficacy beliefs, this article makes three contributions. First, we present a theoretically motivated approach to measuring climate change mitigation efficacy, in light of diverse proposed, perceived, and previously researched strategies. Second, we test this in two national survey samples (Amazon's Mechanical Turk N = 405, GfK Knowledge Panel N = 1,820), demonstrating largely coherent beliefs by level of action and discrimination between types of efficacy. Four additive efficacy scales emerge: personal self‐efficacy, personal response efficacy, government and collective self‐efficacy, and government and collective response efficacy. Third, we employ the resulting efficacy scales in mediation models to test how well efficacy beliefs predict climate change policy support, controlling for specific knowledge, risk perceptions, and ideology, and allowing for mediation by concern. Concern fully mediates the relatively strong effects of perceived risk on policy support, but only partly mediates efficacy beliefs. Stronger government and collective response efficacy beliefs and personal self‐efficacy beliefs are both directly and indirectly associated with greater support for reducing the risks of climate change, even after controlling for ideology and causal beliefs about climate change.     

不动产物权变动登记外的公示方式

按现有立法,不动产物权变动的公示方式均是登记。但立法上却有不登记的例外,实践中也有这种需要。如果法律上能够明确,在一定条件下,不动产的物权变动可以以登记外的公示方式存在,它对于保障交易安全、提高交易效率具有较强的现实意义。为了减少负面效应——实施这种公示方式可能出现的问题,如二重买卖、重复抵押等,可采取相应的措施予以解决。     

自我效度对单词记忆的影响

采用班杜拉的自我效度理论,在大量实证调查的基础上,考察其与单词记忆的关系,为英语词汇教学提供启示.研究表明,较之其它认知或情感因素,自我效度能对学生的学习动机、目标及结果作出更准确的预测和解释.自我效度强的学生在记忆的规律性、记忆方法的技巧性及自我调控的科学性上都要明显优于效度弱的学生.     

当代诗歌集体化写作阶段的读者和民歌形式问题

在1949年至1976年的当代诗歌集体化写作阶段,颂歌建构起了自身独特的传播消费方式和文本形式.工农兵群众作为意识形态的中介,介入并主导着诗歌的生产、传播、阅读和批评等各个话语实践环节,内在地规约了民歌形式的制度化进程.工农兵诗歌及其民歌形式的试验,在一定程度上体现了当代中国创新现代文化体制和追求现代文化的民族化发展道路这两个向度的战略考量,同时也为当前诗歌重建中的"新诗二次革命论"提供了足资借鉴的经验教训.     

商会的产生机理:一个利他主义的解释

对于只提供集体公共产品的商会来说,如果行业内的企业都是利己主义者,且加入商会完全自愿,则"搭便车"的行为会使得集体行动无法实现,商会的发生机制亦将成为难解之迷。假如行业中存在利他主义的企业,其利他行为将使其他企业意识到行业的共同利益,从而抑制各自的机会主义倾向。利他主义者的存在起到了一种"凝结核"的作用,他们除了付出物质上的代价去增进行业的共同利益外,还会付出时间和精力去游说其他企业,推动行业的集体行动。多数行业的市场结构是不完全竞争的,企业规模参差不齐,一些规模较大的企业对于通过集体行动来获得合作剩余有着更强烈的需求,为了增进自身利益和整个集团的利益,这些规模较大的企业会成为商会的发起人。     

无因管理问题的研究

无因管理作为民法法律之债的发生依据之一,应当根据社会的发展赋予其新的价值。本文试从无因管理的社会意义和法律性质、成立条件、效力、类型化及类型化无因管理的法律效果等方面就无因管理的有关问题进行了研究。     

教师效能感研究述评

教师效能感的主要理论模型建构主要有罗特的控制点理论和班杜拉的自我效能理论。教师效能感通过教师行为而对学生自我效能及学习能力与成绩起作用,与此同时,环境因素和教师自身因素也对教师的教学效能感产生影响。     

公务员激励机制对行政效能的影响及其完善

公务员的激励机制是影响行政效能的重要环节。当前我国正处于由旧的人事管理体制向新的国家公务员制度过渡的历史时期 ,因此 ,一方面必须把新的公务员制度落实下去 ;另一方面 ,必须以提高行政效能为目标 ,在考核、工资、晋升、奖惩等制度的具体环节与运行上不断加以完善。     

Improving the contributions of technology assessment to the health care system of the U.S.A.

Summary Based on 14 case studies of highly effective therapies and the reasons they succeeded less frequently than they could, we propose a variety of steps to improve the health care system of the U.S.A. Whatever proposal emerges from current national debates until innovations are shown to be safe and effective, they should not be supported; when slightly better technologies are much more expensive than other good ones we need to consider appropriate choices carefully; simplified billing and bookkeping would reduce our costs; when a technology is rapidly introduced cautionnary measures may be needed; tracking immunization and repairing their omissions requires a new system; educational programs such as seen effective in hypertension should be applied in other areas such as vaccination; in organ transplantation the nation should consider “presumed consent”; our payment system sometimes creates perverse incentives and therefore needs review; and the preferences of the public in allocation of health resources need to be discovered once the public is informed about the issues.
