新媒体环境下科学事件的解读特征与情绪表达——基于新浪微博“基因编辑婴儿”文本的框架研究
Framing “Gene-edited Babies”: Online Discussion and Emotions in Science Controversies
本文以“基因编辑婴儿”为案例，通过网络爬虫技术爬取果壳网、央视新闻等7个微博账号，以其中的165条事件相关微博原文和6440条微博评论为样本进行框架分析，并以恩克曼六种基本情绪指标对评论进行分类。研究发现，“基因编辑婴儿”事件相关微博文本中存在“个人问责”“外部问责”等十个框架。在描述分析基础上，研究利用对应分析（correspondence analysis）检验微博原文框架、评论框架、评论情绪之间的关系。研究发现，原文框架与评论框架存在较强一致性，原文和评论中的“个人问责”“外部问责”和“科普”框架能够一一对应；“个人问责”“外部问责”和“受害者权益”三个框架微博下的评论呈现更明显的负面情绪,“宿命论”和“科普”框架则与快乐情绪相关。此外，综合媒体账号与科普账号存在差异：科普账号的微博原文框架与评论框架的相关性显著高于综合媒体账号，两类账号的原文框架与评论情绪的相关性基本一致。
This study took “gene editing baby” as the key word, extracted 6440 comments from 7 Weibo accounts such as Guoke, CCTV news and so on by using web crawler technology as samples for frame research, and classified the comments by Enkman’s six basic emotional indicators. The research found that in the extracted comment text of “gene-edited baby” event, there are ten frames, such as “personal accountability” and “external accountability”. The comments under the four frames of “responsible scientists”, “external accountability”, “scientific risk” and “scientific background” are more relevant to the original Weibo frames. The negative emotions are more obvious in the comments under the three frames of “individual accountability”, “external accountability” and “victims’ rights”. In addition, there are differences between integrated media account and popular science account: the correlation between original Weibo frames and comment frames of popular science account is significantly higher than that of integrated media account, and the correlation between original Weibo frames and comment emotions of two kinds of account is basically the same.

In this study, I examine whether Americans’ emotions and opinions about nanotechnology are influenced by how the issue is framed. Using data collected from an experiment embedded within a national survey, I find consistent framing effects even though the magnitudes of respondents’ opinion changes are not especially large. Frames about specific risks and benefits of nanotechnology are more influential than frames based on general beliefs about the merits of science, and framing nanotechnology as beneficial is only somewhat less powerful than framing it as risky. I conclude by discussing the implications of these framing effects for future mass opinions about nanotechnology.

The public debate over biotechnology has been especially intense in Switzerland. The frame theory is introduced as a promising approach for better understanding this controversy. One shortcoming of current frame research is the diversity of frame typologies. An attempt to compare and integrate several frame typologies is presented. The theoretical analysis suggests that most of the frames are not issue specific but of a more general nature. The empirical section presents the framing of biotechnology over the past thirty years, during which increasing conflicts paralleled a higher diversity of frames in the media.

J. A. Russell (1994) misrepresents what universality means, misinterprets the evidence from past studies, and fails to consider or report findings that disagree with his position. New data are introduced that decisively answer the central question that Russell raises about the use of a forced-choice format in many of the past studies. This article also shows that his many other qualms about other aspects of the design of the studies of literate cultures have no merit. Russell's critique of the preliterate cultures is inaccurate; he does not fully disclose what those who studied preliterate subjects did or what they concluded that they had found. Taking account of all of Russell's qualms, my analysis shows that the evidence from both literate and preliterate cultures is overwhelming in support of universals in facial expressions.

The affective primacy hypothesis (R. B. Zajonc, 1980) asserts that positive and negative affective reactions can be evoked with minimal stimulus input and virtually no cognitive processing. The present work tested this hypothesis by comparing the effects of affective and cognitive priming under extremely brief (suboptimal) and longer (optimal) exposure durations. At suboptimal exposures only affective primes produced significant shifts in Ss' judgments of novel stimuli. These results suggest that when affect is elicited outside of conscious awareness, it is diffuse and nonspecific, and its origin and address are not accessible. Having minimal cognitive participation, such gross and nonspecific affective reactions can therefore be diffused or displaced onto unrelated stimuli. At optimal exposures this pattern of results was reversed such that only cognitive primes produced significant shifts in judgments. Together, these results support the affective primacy hypothesis.

Substantial research examines the cognitive factors underlying proenviron-mental message effectiveness. In contrast, this study investigates the role of emotion, fear and hope specifically, in the gain/loss framing of environmental policy initiatives. The 2 (threat vs. no threat) × 2 (gain- vs. loss-framed efficacy) experiment revealed emotion, especially hope, as a key mediator between gain-framed messages and desired climate change policy attitudes and advocacy. Results further supported the value of sequencing emotional experiences to enhance persuasive effect. This research offers an inaugural test of emotional flow theorizing and highlights the need for additional research on emotional processes in environmental communication.

How do people judge nanotechnology risks that are completely unfamiliar to them? Drawing on results of previous studies on framing and risk perception, two hypotheses about potential influences on nanotechnology risk perception were examined in an experimental study: 1) Risk perception of nanotechnology is influenced by its benefit perception. 2) Risk perception of nanotechnology is influenced by the context in which nanotechnology is embedded, specifically by the characteristics of the enterprises that profit from nanotechnology: large multinational enterprises versus small and medium-sized enterprises. In contrast to findings for other new technologies, e.g. biotechnology, the different types of benefit did not affect risk perceptions in our study. However, we found that characterizing the enterprises as large multinational versus small or medium-sized leads to differences in risk perception. One can speculate that when personal knowledge about a technology is lacking, people use more familiar aspects from the social context as cues for their risk evaluation.

General journalistic principles guide the ways that gatekeepers evaluate the newsworthiness of events. These principles are adapted in the field of international communication and indicate some unique features, in particular, of international disasters reporting. The current research examined the presence, amount, and length of news coverage from 3 major U.S. newspapers on 292 global natural disasters from 2004 to 2014. Results showed that U.S. newspapers had a reasonable neglect of international disasters compared with domestic ones and a disproportional favor toward huge versus smaller size disasters. A systematic predicting model was evident: Severity was the most significant and the only consistent determinant of disasters reports, followed by the intensity of deviance. Geographic distance and degree of relevance between countries failed to predict any variance of news coverage. This finding might demonstrate a return to the news value that the newsworthiness of an event should be based on the attributes of the event per se.
