Abstract

ABSTRACT This study investigated what (risk) information related to COVID-19 was most amplified through online discussions in environment-focused communities and how amplification and ripple effects evolved over time. The population of posts and comments (N = 14,156 observations) posted to 135 environment-focused subreddits from Dec. 1, 2019-Aug. 31, 2020 containing key terms related to COVID-19 was downloaded and subjected to computational content analysis via Leximancer to observe conceptual phenomena that emerged in the data and extract themes based on word-like associations. To examine how online discussion evolved over time, stepwise segmented regression was employed to identify revolutionary breakpoints – significant changes in the volume of conversation over time. Analysis revealed five time periods in the dataset, and concept maps were generated to understand prominent themes in each. Omnibus results revealed themes highlighting positive and negative environmental consequences associated with COVID-19. Analysis revealed a more nuanced trajectory of how the frequency and content of conversations evolved over time.

关注环境的社区如何在线讨论COVID-19:对Reddit上的社会(风险)放大和连锁反应的分析

本研究调查了在关注环境的社区中，哪些与COVID-19相关的(风险)信息通过在线讨论被放大最多，以及放大和连锁反应是如何随着时间的推移而演变的。2019年12月1日至8月，135个以环境为重点的子reddit上发布的帖子和评论(N = 14156条观察)的数量。下载包含COVID-19相关关键术语的第31号数据库，并通过lexximancer进行计算内容分析，观察数据中出现的概念现象，并基于类词关联提取主题。为了研究在线讨论是如何随着时间的推移而演变的，采用逐步分段回归来确定革命性的断点——随着时间的推移，谈话量发生了重大变化。分析揭示了数据集中的五个时间段，并生成了概念图，以了解每个时间段的突出主题。综合结果揭示了与COVID-19相关的积极和消极环境后果的主题。分析揭示了一个更微妙的轨迹，即对话的频率和内容是如何随着时间的推移而变化的。

期刊介绍： Environmental Communication is an international, peer-reviewed forum for multidisciplinary research and analysis assessing the many intersections among communication, media, society, and environmental issues. These include but are not limited to debates over climate change, natural resources, sustainability, conservation, wildlife, ecosystems, water, environmental health, food and agriculture, energy, and emerging technologies. Submissions should contribute to our understanding of scientific controversies, political developments, policy solutions, institutional change, cultural trends, media portrayals, public opinion and participation, and/or professional decisions. Articles often seek to bridge gaps between theory and practice, and are written in a style that is broadly accessible and engaging.
