The warm glow of recycling can make us more wasteful

Laudable initiatives designed to limit the environmental damage associated with consumption, such as the recycling of plastic packaging into clothing or unused bread into beer, have become increasingly popular. In three experiments, we show how such initiatives can potentially increase waste rather than preventing it. Specifically, we show that when presented with such options people may come to psychologically frame their waste creation as a contribution to the collective good that makes them feel good about themselves (i.e. eliciting a warm-glow effect). We argue that such potential ‘wasteful contribution’ effects need to be considered in assessing the true sustainability benefits of certain recycling initiatives

Communication strategies for moral rebels:How to talk about change in order to inspire self-efficacy in others

Current carbon-intensive lifestyles are unsustainable and drastic social changes are required to combat climate change. To achieve such change, moral rebels (i.e., individuals who deviate from current behavioral norms based on ethical considerations) may be crucial catalyzers. However, the current literature holds that moral rebels may do more harm than good. By deviating from what most people do, based on a moral concern, moral rebels pose a threat to the moral self-view of their observers who share but fail to uphold that concern. Those observers may realize that their behavior does not live up to their moral values, and feel morally inadequate as a result. Work on “do-gooder derogation” demonstrates that rebel-induced threat can elicit defensive reactance among observers, resulting in the rejection of moral rebels and their behavioral choices. Such findings suggest that advocates for social change should avoid triggering moral threat by, for example, presenting nonmoral justifications for their choices. We challenge this view by arguing that moral threat may be a necessary ingredient to achieve social change precisely because it triggers ethical dissonance. Thus, instead of avoiding moral justifications, it may be more effective to harness that threat. Ethical dissonance may offer the fuel needed for observers to engage in self-improvement after being exposed to moral rebels, provided that observers feel capable of changing. Whether or not observers feel capable of changing, however, depends on how rebels communicate their moral choices to others—how they talk about change.

Too hot to handle:Depoliticisation and the discourse of ecological modernisation in fire management debates

The management of fire within landscapes is a topic of increasing contestation. This is particularly the case in relation to the practice of ‘prescribed burning’, which aims to exercise a form of control of wild fires through the application of science-based techniques that putatively reconcile the conservation of biodiversity with the protection of human life and property in particular places. The belief in possibilities to solve environmental problems by scientific approaches and in outcomes that do not involve harm or vulnerabilities is an element of a trend called “Ecological Modernisation” (EM). Various studies have shown how discourses of EM have come to dominate the ways in which many contemporary environmental problems are approached. We argue that highlighting the presentation of such discourses as neutral and non-politicised precludes a critical examination of the ways in which the knowledge claims upon which they rest can be seen to reinforce only particular sets of constructions of the relationship between humans and the natural world. Through an analysis of knowledge claims made in relation to recurring topics such as the use of fire by Indigenous Australians and the adaptation of species to fire, we illustrate that behind the discourse of ecological modernisation sit deeply engrained variations in terms of where people locate vulnerability in relation to the pressing problem of wildfire and fire management. We argue that the depoliticisation of the topic sustains specific types of relationships between people and nature while delegitimising others and obscures the fundamentally different notions about relationships between humans and non-human nature upon which the debate ultimately pivots

The mitochondrial genome of the venomous cone snail conus consors

Cone snails are venomous predatory marine neogastropods that belong to the species-rich superfamily of the Conoidea. So far, the mitochondrial genomes of two cone snail species (Conus textile and Conus borgesi) have been described, and these feed on snails and worms, respectively. Here, we report the mitochondrial genome sequence of the fish-hunting cone snail Conus consors and describe a novel putative control region (CR) which seems to be absent in the mitochondrial DNA (mtDNA) of other cone snail species. This possible CR spans about 700 base pairs (bp) and is located between the genes encoding the transfer RNA for phenylalanine (tRNA-Phe, trnF) and cytochrome c oxidase subunit III (cox3). The novel putative CR contains several sequence motifs that suggest a role in mitochondrial replication and transcription

Network analysis reveals open forums and echo chambers in social media discussions of climate change

Open Access articleAction to tackle the complex and divisive issue of climate change will be strongly influenced by public perception. Online social media and associated social networks are an increasingly important forum for public debate and are known to influence individual attitudes and behaviours yet online discussions and social networks related to climate change are not well understood. Here we construct several forms of social network for users communicating about climate change on the popular microblogging platform Twitter. We classify user attitudes to climate change based on message content and nd that social networks are characterised by strong attitude-based homophily and segregation into polarised "sceptic" and "activist" groups. Most users interact only with like-minded others, in communities dominated by a single view. However, we also nd mixed-attitude communities in which sceptics and activists frequently interact. Messages between like-minded users typically carry positive sentiment, while messages between sceptics and activists carry negative sentiment. We identify a number of general patterns in user behaviours relating to engagement with alternative views. Users who express negative sentiment are themselves the target of negativity. Users in mixed- attitude communities are less likely to hold a strongly polarised view, but more likely to express negative sentiment towards other users with di ering views. Overall, social media discussions of climate change often occur within polarising "echo chambers", but also within "open forums", mixed-attitude communities that reduce polarisation and stimulate debate. Our results have implications for public engagement with this important global challenge.Engineering and Physical Sciences Research Council (EPSRC) - Bridging the Gaps initiativ

Quantifying the Importance of Socio-Demographic, Travel-Related, and Psychological Predictors of Public Acceptability of Low Emission Zones

As ambient air pollution increases, governments are imposing traffic management strategies to improve air quality. A common strategy is the implementation of Low Emission Zones (LEZs), which have generated considerable public debate. Nonetheless, little research has explored which factors determine their public acceptability. Previous empirical studies have also typically lacked power for regression analyses and have not determined the relative importance of different predictors. After conducting a large online survey in a UK city, well-powered multiple regression and dominance analyses demonstrated that psychological factors, such as environmental moral obligation, were the most important predictors of LEZ acceptability. However, travel-related and socio-demographic factors, such as distance lived from the LEZ and having dependent children, were also unique and important predictors. Overall, we argue that, whilst psychological factors are important, travel-related and socio-demographic barriers must not be overlooked during LEZ implementation

Towards an understanding of when non-climate frames can generate public support for climate change policy

There is a growing tendency for policy makers to frame climate change action in terms of non-climate benefits, raising important empirical questions regarding the utility of such approaches. Across three studies we explore whether (and when) non-climate frames can lead to greater support for climate policy relative to climate frames. In Study 1 we framed a car-use reduction policy in relation to climate change or public health and showed that non-climate frames can stimulate greater support for climate policy. Study 2 explored frame relevance as a potential boundary condition to the efficacy of non-climate frames. Study 3 found that attempts to frame climate policy in relation to non-climate issues that affect participants personally can fail if that issue is not seen as being sufficiently relevant. We suggest that non-climate frames can be an effective tool in stimulating support for climate policy, however greater consideration of the key mechanisms is required. </jats:p

A comparison of prebunking and debunking interventions for implied versus explicit misinformation

Psychological research has offered valuable insights into how to combat misinformation. The studies conducted to date, however, have three limitations. First, pre-emptive (“prebunking”) and retroactive (“debunking”) interventions have mostly been examined in parallel, and thus it is unclear which of these two predominant approaches is more effective. Second, there has been a focus on misinformation that is explicitly false, but misinformation that uses literally true information to mislead is common in the real world. Finally, studies have relied mainly on questionnaire measures of reasoning, neglecting behavioural impacts of misinformation and interventions. To offer incremental progress towards addressing these three issues, we conducted an experiment (N = 735) involving misinformation on fair trade. We contrasted the effectiveness of prebunking versus debunking and the impacts of implied versus explicit misinformation, and incorporated novel measures assessing consumer behaviours (i.e., willingness-to-pay; information seeking; online misinformation promotion) in addition to standard questionnaire measures. In general, we found debunking to be more effective than prebunking, although both were able to reduce misinformation reliance. We also found that individuals tended to rely more on explicit than implied misinformation both with and without interventions

Properties of nickel-phosphorous coatings codeposited by the electroless and electrochemical plating process

At present, despite numerous studies and practical application, the process of chemical nickel plating remains imperfect. The low nickel deposition rate, the high consumption of the solution components, and the complexity of the deposition process do not contribute to the widespread use of chemical nickel plating. At the same time, chemically deposited coatings are significantly different from the electrochemical: they possess valuable properties. In the paper, the intensification method of chemical nickel plating considered through the use of the co-deposition process with chemical and electrochemical methods. The co-deposition was carried out in an acidic electrolyte solution on an aluminum plate with the stationary potential shift from - 0.01 to - 0.25 V with the use of three electrode system. The presented technique of intensification due to the combination of nickel deposition processes by chemical and electrochemical methods is able to increase the deposition rate of the coatings, and also allows influencing their composition and mechanical properties
