Of all the online information tools that the public relies on to collect information and share opinions about scientific and environmental issues, Twitter presents a unique venue to assess the spontaneous and genuine opinions of networked publics, including those about a focusing event like the Fukushima Daiichi nuclear accident following the 2011 Tohoku earthquake and tsunami. Using computational linguistic algorithms, this study analyzes a census of English-language tweets about nuclear power before, during, and after the Fukushima nuclear accident. Results show that although discourse about the event may have faded rapidly from the news cycle on traditional media, it evoked concerns about reactor safety and the environmental implications of nuclear power, particularly among users in U.S. states that are geographically closer to the accident site. Also, while the sentiment of the tweets was primarily pessimistic about nuclear power weeks after the accident, overall sentiment became increasingly neutral and uncertain over time. This study reveals there is a group of concerned citizens and stakeholders who are using online tools like Twitter to communicate about global and local environmental and health risks related to nuclear power. The implications for risk communication and public engagement strategies are discussed.

In this article it is investigated the relationship between advertising and sustainability by evaluating the perceptions of employees of advertising agencies in the Pan-Amazon region using pre-defined indicators. Seeking to identify the level of environmental practices adopted by advertising agencies toward the goal of building a sustainable society, it was interviewed advertising professionals about whether they saw themselves as contributing to changing consumer society towards a new society based on economic efficiency, social equality and ecological equilibrium. To answer these questions it was used quantitative survey data complemented by qualitative research using in-depth interviews. Results suggest that, from the point of view of advertising professionals, advertising agencies do not have much interest in contributing to a more sustainable society. Moreover, our research showed how the lack of strong ties within advertising trade associations further contribute to the weakness of efforts aimed at this area.

The use and availability of digital media is changing researchers' roles and simultaneously providing a route for a more engaging relationship with stakeholders throughout the research process. Although the digital realm has a profound influence on people's day-to-day lives, some researchers have not yet professionally embraced digital technologies. This paper arises from one aspect of a project exploring how university research and professional practices are evolving as researchers engage with stakeholders via digital media to create, share and represent knowledge together. Using researchers from the Open University (U.K.) as a case study, this paper reviews the extent to which they are developing multiple identities and functions in their engaged research through digital media.

The twenty-first century has witnessed a shift in science communication ideals from one-way science popularization activities towards more reflexive, participatory approaches to public engagement with science. Yet our longue duéee histories of science communication's antecedents focus on the former and have neglected the latter. In this paper I identify parallels between modern science communication ideals and an iconic Enlightenment text, Condorcet's Sketch for a Historical Picture of the Progress of the Human Mind (1795). I show that Condorcet's carefully negotiated balance between scientific reason and radical principles of democracy has much in common with twenty-first century debates about science communication.

The authors present a quantitative content analysis to assess the use of mathematical information in the news of five generalist Portuguese newspapers during a three-month period. Misuses of mathematics were also studied in this context. Results show that only a small percentage of the news articles have mathematical information when compared to previous studies in the field. Furthermore, over 30% of the news articles containing mathematical information have some type of mathematical error. Different categories of errors are defined and reasons why these might occur are discussed.

This article provides a first statistical analysis of the typologies and characteristics of popular science web videos on YouTube. An analysis of 190 videos from 95 online video channels was conducted. Several factors such as narrative strategies, video editing techniques, and design tendencies with regard to cinematography, the number of shots, the kind of montage used, and even the use of sound design and special FX point to a notable professionalism among science communicators independent of institutional or personal commitments. This analysis represents an important step in understanding the essence of current popular science web videos and provides an evidence-based description of their distinctive features.

This study aims to investigate whether different types of museum visits have specific ways to influence the visitors' experience and learning. Three types of museum visits as offered by the Museo della Scienza e della Tecnologia "Leonardo da Vinci" in Milan, Italy were taken into consideration: free tour, guided tour, and lab. The study involved visitors over 25 years of age. The way visits took place, the visitors' learning and experiences were investigated based on evidence collected using methods such as Personal Meaning Mapping and observation. Our study has revealed that the outcomes of the visits vary in terms of visitor experience and depth of knowledge on the main subject. No significant differences were found as concerns the level of attention (visitors proved to be attentive while at the museum regardless of the type of visit).

Volunteer water quality monitors represent the intersection between citizen science and environmental stewardship. Understanding what motivates participation will enable project managers to improve recruitment and retention. This survey of 271 volunteers from eight water quality monitoring organizations in the U.S. found the strongest motivators to participate are helping the environment or community and contributing to scientific knowledge. No variation by gender was found, but younger volunteers have different motivations and preferences than older volunteers. Volunteers value the communication of tangible results more than recognition or reward.

We investigate the development of scientific content knowledge of volunteers participating in online citizen science projects in the Zooniverse (http://www.zooniverse.org). We use econometric methods to test how measures of project participation relate to success in a science quiz, controlling for factors known to correlate with scientific knowledge. Citizen scientists believe they are learning about both the content and processes of science through their participation. We don't directly test the latter, but we find evidence to support the former — that more actively engaged participants perform better in a project-specific science knowledge quiz, even after controlling for their general science knowledge. We interpret this as evidence of learning of science content inspired by participation in online citizen science.

There is growing recognition that effective science communication should not merely focus on addressing scientific literacy but must also open dialogue between scientists and the public, build trust, and increase public interest in environmental research. Citizen science BioBlitzes offer a useful approach for science communicators to address many of these key aims. We explore the BioBlitz concept, learnings and outcomes based on a case study of a BioBlitz held in Sydney, Australia. We found that participants valued learning about biodiversity on the day and importantly, all participants (scientists and citizen scientists) rated interacting and learning from the experience as one of the main benefits.
