'Climate change' from the audience perspective. Perception and interpretation of a scientific topic in the process of public communication. Climate change communication in online public arenas and its effects.

本研究项目的目的是研究一般媒体用户如何感知和解释气候变化，以及媒体如何影响他们的知识和态度。气候变化是一种抽象的现象，无法通过感官单独感知。尽管对人为全球变暖的科学共识越来越多，但科学产生的有关后果和程度的气候知识仍然相互矛盾，脆弱和不确定。媒体对于这一社会相关话题的传播非常重要。在本项目的第一和第二阶段研究中，我们开发了媒体使用和媒体效果的多因素模型，并调查了1）媒体使用与知识，问题意识和行为意图之间的相关性关于气候变化;和2）受众的媒体占用过程。在第三阶段，我们将审查关于气候变化的在线交流。在过去几年中，一般的在线交流，特别是关于气候变化的在线交流变得更加相关，但缺乏关于气候变化在线交流的研究。该研究项目将有助于填补这一研究空白。作为理论基础，我们将使用施密特（在印刷）的互联网中的公共概念，这将被整合到我们的媒体使用和媒体效果的多因素模型。这一概念考虑到网上内容的多样性，其中包括大众传播和人际传播以及各种形式的媒体使用和接收。我们认为，公众的不同交际环境，以及网络公共场合之间的联系影响着人们对网络交际的感知、选择和效果。我们有一个混合方法的研究设计：1）我们将进行一个关于媒体的接收和气候变化的影响的实证研究的元分析，以分析他们的概念和外行的气候变化知识的操作。其目的是解释经验发现中的不一致性，并在未来的研究中更精确地操作知识，特别是关于社交媒体中关于气候变化的外行知识。2)我们将在KlimaRez II小组调查的同时，对不同在线公共领域的气候变化传播进行定量在线内容分析，以比较调查结果，并对在线内容的“生产者”进行额外的定量调查。3)我们将在不同的公共场合进行定性的网络分析，以研究讨论。4)我们将实现对在线气候传播的“生产者”的参与性观察，以了解选择和接收过程。这项研究设计使我们能够精确地检查不同在线公共场所的内容与气候相关知识和态度之间的关系。

The purpose of this research project is to examine how the general media users perceive and interpret climate change and how the media influence their knowledge and attitude. Climate change is an abstract phenomenon, which is not individually perceptible by the senses. Despite the increasing scientific consensus on the anthropogenic global warming, the scientifically generated climate knowledge concerning the consequences and extent remains conflicting, fragile and uncertain. The media are very important for the communication of this socially relevant topic. In the first and second research phases of this project, we developed the multi-factorial model of media use and media effects and investigated 1) the correlation between media use and knowledge, problem awareness and behavioural intentions regarding climate change; and 2) the process of media appropriation of the recipients. In the third phase, we are going to examine the online communication on climate change. Online communication in general and especially concerning climate change has become more relevant within the last years, but there is a lack of research of online communication on climate change. This research project will contribute to fill this research gap. As theoretical foundation, we will use an adapted concept of public in the Internet of Schmidt (in print), which will be integrated into our multi-factorial model of media use and media effects. The concept takes into account the diversity of online contents, which include mass-mediated and interpersonal communication and mixed forms of media use and reception. We assume that different communicative settings of public, as well as the connection among online public arenas influence the perception, selection and effect of online communication. We have a mixed methods research design:1) We will conduct a meta-analysis of empirical studies regarding the media reception and effects of climate change to analyse their concepts and operationalizations of the laypeople-knowledge on climate change. Its purpose is to explain inconsistencies in the empirical findings and operationalize knowledge more precisely in future research, particularly about laypeople-knowledge on climate change in Social Media. 2) We will hold a quantitative online content analysis on climate change communication in different online public arenas, which are conducted at the same time as the panel survey from KlimaRez II to compare the findings, as well as an additional quantitative survey of 'produsers' of the online contents. 3) We will conduct a qualitative netnographic analysis in different public arenas to examine discussions. 4) We will realise a participant observation of 'produsers' of online climate communication to understand the processes of selection and reception.This research design enables us to examine precisely the relation between contents of different online public arenas and climate-related knowledge and attitude.
