In September 2013 the Intergovernmental Panel on Climate Change published its Working Group 1 report, first comprehensive assessment of physical climate science in six years, constituting a critical event societal debate about change. This paper analyses nature this one public forum: Twitter. Using statistical methods, tweets were analyzed to discover hashtags used when people tweeted IPCC and how Twitter users formed communities around their conversational connections. short, presents...
Over the past decade, scientists and journalists have prominently utilized metaphor of a tipping point for drastic, irreversible dangerous climate change. This paper shows how became multi-purpose bridge between science news media, describing its meaning use developed diversified in interaction these two domains. Within scientific domain, from rhetorical device conveying warning change to theoretical concept driving empirical research. The media soon picked up abrupt change, turning it into...
“Stem cell research” has become a subject of political discussion in recent years because its social and ethical implications. The intellectual research program, however, history several decades. Therapeutic applications patents on the basis stem became available during 1990s. Currently, main are found marrow transplantation (e.g., for treatment leukemia). In this study, various meanings term examined these different contexts research, applications, policy debates. Translation mechanisms...
The framing of issues in the mass media plays a crucial role public understanding science and technology. This article contributes to research concerned with analysis frames over time by making an analytical distinction between implicit explicit frames, introducing automated method for frames. In particular, we apply semantic maps case study on newspaper debate about artificial sweeteners, published New York Times 1980 2006. Our results show that changes enables us filter out dynamics detect...
Purpose – The purpose of this paper is to present a study about gender differences in the climate change communication on Twitter and use affordances Twitter. Design/methodology/approach data set consists 250,000 tweets retweets for which authors’ was identified. While content hashtags used were analysed common topics specific contexts, usernames that proportionately more frequently mentioned by either male or female tweeters coded according usernames’ stance debate into convinced (that...
Social media platforms provide major opportunities for online activism and the emergence of digital counterpublics. Research on counterpublics has focused actors their narrative strategies aiming at deconstructing dominant discourses. Less attention been paid to how interplay between platform-specific functions affects configurations therewith also success Existing studies mainly rely determining up front which topics, actor characteristics, or arguments constitute hashtag In contrast, our...
This paper introduces a new approach to detecting scientists' field mobility by focusing on an author's self-citation network, and the co-authorships keywords in self-citing articles. Contrary much previous literature self-citations, we will show that patterns reveal important information development emergence of research topics over time. More specifically, discuss self-citations as means detect mobility. We introduce network based definition mobility, using Optimal Percolation Method...
This paper offers a framework for examining the relationship between social, instrumental, and technological determinants of participation through social media (Dahlberg, 2004) using discursive approach based in concepts frames framing (Goffman, 1974; Snow & Benford, 1992). We apply our multideterminant to investigate participatory dynamics on YouTube case climategate. Our interpretive analysis videos comments shows how public responses climategate were scripted around 3 dominant master...
Social media data provide increasing opportunities for the automated analysis of large sets textual documents. So far, tools have been developed either to account social networks among participants in debates, or analyze content these debates. Less attention has paid mapping co‐occurrences actors (participants) and topics (content) online debates that can be considered as socio‐semantic networks. We propose a new, approach uses whole matrix co‐addressed understanding visualizing show...
Changes in the biosciences and their relations to society over last decades provide a unique opportunity examine whether or not such changes leave traces language we use talk about them. In this article metaphors used English-speaking press coverage conceptualize new type of (interdisciplinary) bioscience: synthetic biology. Findings show that three central were between 2008 May 2010. They exploit social cultural knowledge books, computers engines are linked revolutions science (the...
For the biomedical sciences, Medical Subject Headings (MeSH) make available a rich feature which cannot currently be merged properly with widely used citing/cited data. Here, we provide methods and routines that MeSH terms amenable to broader usage in study of science indicators: using Web-of-Science (WoS) data, one can generate matrix citing versus cited documents; PubMed/MEDLINE documents generated analogously. The two matrices also reorganized into 2-mode references. Using abbreviated...
Recently, the field of strategic communication has been criticized for lacking a coherent theoretical synthesis. Recognizing that is sub-discipline science, we study how anchored in corpus established theories – including social interpretative, and critical approaches. To describe use, development, context publications, analyzed all articles published ten public relations/ corporate communication/ organizational journals over twenty years (N = 4,027). While vast majority did not refer to one...
Metaphors such as "clones are mass products" always can be used for opposing purposes if both clones and products have many features in common from which to select. This results complex novel events being opposed fashions metaphors. To test this claim, discussions of Dolly, the cloned sheep, consistent with claim "CLONES ARE MASS PRODUCTS" The Times Nature 1997, were examined. Mass viewed perfectly similar and, therefore, things one repose confidence a purchaser, or inferior assembly-line...
This article examines the shifts and changes in metaphors used to describe human genome project (HGP) between 2000 2003, with year 2001 as a trigger for genomic metaphorical reflection. We want answer questions, such as: Did findings announced shake foundations on which HGP had been built or not? novel capture imagination of scientists public did old survive throughout this period? What influence does continuity discontinuity framing have perception well its scientific understanding? To...
The metaphor of "Frankenfood" rapidly spread into popular use at the end 1990s, to extent that it was even added New Oxford Dictionary Phrase and Fable, 2000 edition. gained wide popularity least partly because active campaigns various NGOs on their Web pages. also widely used in more informal e-mail newsgroups Web, seemed provide common ground for different discourses. In this article, I explore way metaphors relate discourses Internet. This approach may open up new ways analyzing both...
Four years after the completion of Human Genome Project, US National Institutes for Health launched Microbiome Project on 19 December 2007. Using metaphor analysis, this article investigates reporting in English-language newspapers advances microbiomics from 2003 onwards, when word "microbiome" was first used. This research said to open up a "new frontier" and conceived as "second human genome project", time focusing genomes microbes that inhabit populate humans rather than itself. The...
