Metaphors and Diaphors in Science Communication: Mapping the Case of Stem Cell Research

“Stem cell research” has become a subject of political discussion in recent years because of its social and ethical implications. The intellectual research program, however, has a history of several decades. Therapeutic applications and patents on the basis of stem cell research became available during the 1990s. Currently, the main applications of stem cell research are found in marrow transplantation (e.g., for the treatment of leukemia). In this study, the various meanings of the term stem cell are examined in these different contexts of research, applications, and policy debates. Translation mechanisms between contexts are specified, and a quantitative indicator for the degree of codification is proposed.

Measuring the meaning of words in contexts: An automated analysis of controversies about 'Monarch butterflies,' 'Frankenfoods,' and 'stem cells'

SummaryCo-words have been considered as carriers of meaning across different domains in studies of science, technology, and society. Words and co-words, however, obtain meaning in sentences, and sentences obtain meaning in their contexts of use. At the science/society interface, words can be expected to have different meanings: the codes of communication that provide meaning to words differ on the varying sides of the interface. Furthermore, meanings and interfaces may change over time. Given this structuring of meaning across interfaces and over time, we distinguish between metaphors and diaphors as reflexive mechanisms that facilitate the translation between contexts. Our empirical focus is on three recent scientific controversies: Monarch butterflies, Frankenfoods, and stem-cell therapies. This study explores new avenues that relate the study of co-word analysis in context with the sociological quest for the analysis and processing of meaning.

Climate change on Twitter: topics, communities and conversations about the 2013 IPCC Working Group 1 report

In September 2013 the Intergovernmental Panel on Climate Change published its Working Group 1 report, the first comprehensive assessment of physical climate science in six years, constituting a critical event in the societal debate about climate change. This paper analyses the nature of this debate in one public forum: Twitter. Using statistical methods, tweets were analyzed to discover the hashtags used when people tweeted about the IPCC report, and how Twitter users formed communities around their conversational connections. In short, the paper presents the topics and tweeters at this particular moment in the climate debate. The most used hashtags related to themes of science, geographical location and social issues connected to climate change. Particularly noteworthy were tweets connected to Australian politics, US politics, geoengineering and fracking. Three communities of Twitter users were identified. Researcher coding of Twitter users showed how these varied according to geographical location and whether users were supportive, unsupportive or neutral in their tweets about the IPCC. Overall, users were most likely to converse with users holding similar views. However, qualitative analysis suggested the emergence of a community of Twitter users, predominantly based in the UK, where greater interaction between contrasting views took place. This analysis also illustrated the presence of a campaign by the non-governmental organization Avaaz, aimed at increasing media coverage of the IPCC report.

Implicit media frames: automated analysis of public debate on artificial sweeteners.

The framing of issues in the mass media plays a crucial role in the public understanding of science and technology. This article contributes to research concerned with the analysis of media frames over time by making an analytical distinction between implicit and explicit media frames, and by introducing an automated method for the analysis of implicit frames. In particular, we apply a semantic maps method to a case study on the newspaper debate about artificial sweeteners, published in the New York Times between 1980 and 2006. Our results show that the analysis of semantic changes enables us to filter out the dynamics of implicit frames, and to detect emerging metaphors in public debates. Theoretically, we discuss the relation between implicit frames in public debates and the codification of meaning and information in scientific discourses, and suggest further avenues for research interested in the automated analysis of frame changes and trends in public debates.

Self-citations, co-authorships and keywords: A new approach to scientists’ field mobility?

This paper introduces a new approach to detecting scientists’ field mobility by focusing on an author’s self-citation network, and the co-authorships and keywords in self-citing articles. Contrary to much previous literature on self-citations, we will show that author’s self-citation patterns reveal important information on the development and emergence of new research topics over time. More specifically, we will discuss self-citations as a means to detect scientists’ field mobility. We introduce a network based definition of field mobility, using the Optimal Percolation Method (Lambiotte & Ausloos, 2005; 2006). The results of the study can be extended to selfcitation networks of groups of authors and, generally also for other types of networks.

Genomics: shifts in metaphorical landscape between 2000 and 2003

This article examines the shifts and changes in the metaphors used to describe the human genome and the human genome project (HGP) between 2000 and 2003, with the year 2001 as a trigger for genomic and metaphorical reflection. We want to answer questions, such as: Did the findings announced in 2001 shake the metaphorical foundations on which the HGP had been built or not? Did novel metaphors capture the imagination of scientists and the public or did old metaphors survive throughout this period? What influence does the continuity or discontinuity in metaphorical framing of the HGP have on the public perception of the HGP as well as on its scientific understanding? To answer these questions we have systematically compared the metaphors used in one major scientific journal, Nature, and in one major UK newspaper, the online edition of the Guardian/The Observer during a period of two months around June 2000, February 2001 and April 2003.

Multiple presents: how search engines rewrite the past

Internet search engines function in a present which changes continuously. The search engines update their indices regularly, overwriting webpages with newer ones, adding new pages to the index and losing older ones. Some search engines can be used to search for information on the internet for specific periods of time. However, these ‘date stamps’ are not determined by the first occurrence of the pages in the web, but by the last date at which a page was updated or a new page was added and the search engine’s crawler updated this change in the database. This has major implications for the use of search engines in scholarly research as well as theoretical implications for the conceptions of time and temporality. This article examines the interplay between the different updating frequencies by using AltaVista and Google for searches at different moments of time. Both the retrieval of results and the structure of retrieved information erodes over time.

Synthetic biology: building the language for a new science brick by metaphorical brick

Changes in the biosciences and their relations to society over the last decades provide a unique opportunity to examine whether or not such changes leave traces in the language we use to talk about them. In this article we examine metaphors used in English-speaking press coverage to conceptualize a new type of (interdisciplinary) bioscience: synthetic biology. Findings show that three central metaphors were used between 2008 and May 2010. They exploit social and cultural knowledge about books, computers and engines and are linked to knowledge of three revolutions in science and society (the printing, information and industrial revolutions). These three central metaphors are connected to each other through the concepts of reading/writing, designing and mass production and they focus on science as a revolutionary process rather than on the end results or products of science. Overall, we observed the use of a complex bricolage of mixed metaphors and chains of metaphors that root synthetic biology in historical events and achievements, while at the same time extolling its promises for the future.

From “Burning Library” to “Green Medicine” The Role of Metaphors in Communicating Biodiversity

In public discourse on the environment, scientific knowledge is often mediated by metaphors. In this article, the authors are concerned with the role of metaphors in the communication of biodiversity loss. More specifically, their examination focuses on such popular metaphors as “the library of life,” “biotic holocaust,” and “the Holy Grail” and on the role of these metaphors in putting biodiversity loss on the global environmental agenda. These metaphors reflect two opposite narratives on environmental politics: the apocalyptic narrative of species extinction and the new narrative of hope that looks at genetic engineering.

Investigating Participatory Dynamics Through Social Media Using a Multideterminant Frame Approach: The Case of Climategate on YouTube

This paper offers a framework for examining the relationship between social, instrumental, and technological determinants of participation through social media Dahlberg, 2004 using a discursive approach based in the concepts of frames and framing Goffman, 1974; Snow & Benford, 1992. We apply our multideterminant framework to investigate participatory dynamics on YouTube in the case of climategate. Our interpretive analysis of videos and comments shows how public responses to climategate were scripted around 3 dominant master frames, reinforced by calls to collective action and media form. Our multideterminant framework makes a contribution to the debate over the transformative potential of social media by providing a method to assess the relative value of social media in response to specific social problems.
