The impact of visual information on perceptions of water resource problems and management alternatives

To assess changes in human understanding and decision making, the paper examines (1) the influence of visual information on perceptions about groundwater management in Phoenix, Arizona and (2) the correlates and dimensions underlying people's views about water scarcity and mitigation strategies. While perceptions entrenched in ideologies are difficult to change, different types of information (three-dimensional versus two-dimensional) have distinct impacts on the perceived magnitude of problems compared to judgements about their causes and solutions. Overall, visual information may be especially useful for developing a shared understanding of problems and a collective vision for management alternatives. Additional implications of this study for fostering environmental awareness, policy support, and collaborative decision making are also discussed.     

基于互联网的自然灾害风险沟通平台研究

通过调查发现,国内自然灾害风险沟通平台尚不完善,普遍存在沟通主体分类不清、风险消息真假难辨、沟通方式单一等不足之处,本文针对这些问题开展研究。通过案例分析,明确将沟通主体分为政府、专家和公众三类;利用多指标综合评价法构建面向沟通过程的自然灾害风险消息评价体系;并集成多种网络通信技术建设一个基于互联网的自然灾害风险沟通示...     

The Role of Fictional Film Exposure and Narrative Engagement for Personal Norms,Guilt and Intentions to Protect The Climate

ABSTRACT

Using an integration of Norm Activation Theory, Value-Belief-Norm Theory and Narrative Persuasion, this study investigates the ability of an eco-dystopian science fiction film set in a world of excessive solar radiation to support intentions for pro-environmental behavior. Specifically, the influence of narrative engagement and explicit references to human responsibility for climate change are tested. A 2 (high vs. low narrative engagement) x?3 (human responsibility frame vs. temperature frame vs. no frame) plus control group (no film) experiment was conducted (n?=?257). Results show that compared to the control condition, the film had an indirect effect on behavioral intentions by raising the personal norm (a sense of personal obligation to act). The temperature change and human responsibility frames did not show any influence, while narrative engagement had an indirect effect on intentions by increasing guilt. The results are discussed with regard to their theoretical and practical implications.     

均等指数和两极化指数建立与比较

在基尼系数衡量收入差距存在一定缺陷和我国收入两极化概念不清楚的情况下,本文重点对基尼系数与两极分化的涵义进行了剖析,指出了两个概念的本质与它们之间的联系、区别。对以后的收入差距测量有一定的指导意义。基尼系数反映了所有个体偏离总体的程度,两极化指数反映二大组之间差异情况。在前人测量收入差距方法基础上构造两极分化指数I。结合中国和部分其它国家的数据,测量了三个指数并进行了比较分析,结果表明:三个指数高度相关,在一般情况下均等指数、基尼系数和两极分化指数都能大致反映收入差距情况。对组间、组内差距处理方法不同是基尼系数(均等指数)与两极分化指数最根本的区别。构造的两极分化指数具有直观、易于理解、意义明确、计算简单等诸多优点。因此在测量收入差距时,倡导优先使用均等指数。在测量只有二等分组构成总体的收入差距时,优先选择两极分化指数。实际研究中,可以根据研究的问题,合理地选择基尼系数,均等指数,两极分化指数从事相关研究。     

Reduction of Tobacco Smoking Health Risk Through an Appropriate Media Based Communication Strategy in Uganda

The health impacts of tobacco consumption are well documented and have gained acceptance worldwide. Today, a substantial, preventable burden of tobacco attributable diseases exists in most countries, though in most of the cases, unknown. Smoking accounts for almost half of the deaths in middle age in some regions. In Uganda, translating findings into policy action is slow and involves several stakeholders. It will continue to require support from tobacco control campaign groups. This paper analyses secondar...     

An empirical research on the determinants of Chinese college students’ carbon label cognition and interpersonal communication willingness

Carbon labels are innovative medium and tools for climate change communication and low-carbon marketing. This study aims at examining how college students are aware of low-carbon and carbon labels, whether they are more willing to communicate low-carbon ideas, and also the determinants affecting their interpersonal communication of carbon labels. The multiple regression analysis shows that Chinese college students’ willingness of interpersonal communication of carbon labels are significantly influenced by their awareness of climate change crisis, the perceived value of carbon labels, the consideration of product environmental attributes, the preferences of carbon labels, the household background, and their educational background. In response to these factors, this paper proposes, in a public perspective, the strategies to enhance the dissemination of carbon labels.
