To clarify uncertainty in predictions of the quantity, radionuclide inventory and activity of waste from the Krsko nuclear power plant, and to illuminate its role in related policy‐making, we made a scenario analysis in order to find out the variation in waste characteristics if the plant operates five years shorter or longer than anticipated, or if it uses fuel of a higher enrichment (levels between 3 per cent and 5 per cent of U‐235). We used ORIGEN2 computer code for calculations connected to spent fuel, and developed a code for calculating low‐ and intermediate‐level waste. We present and interpret our results using language which can be understood by decision makers and the general public. We believe that the clarification of the issues gained through our analysis will contribute to more informed decision making and be effective in building confidence among professionals, the public and politicians in the process of identifying the most appropriate waste management options.

This work aims to examine the communication on Twitter of the most responsible companies in Spain to identify the topics covered on corporate social responsibility (CSR) from the perspective of happiness and social marketing. In addition, the profiles of the messages that show an association with the impact of the messages have been identified.

An empirical analysis of the Twitter posts of Spain's ten most responsible companies has been carried out. The methodology of this work combines data mining techniques, sentiment analysis and content analysis, both from a quantitative and qualitative approach.

The results show that most brand tweets do not deal with CSR-related topics. The topics they address the most are those related to sports and the weather. From the perspective of social marketing, conversational-type tweets are the most published and have achieved the most significant reaction from the public. In addition, four messages' profiles have been identified based on the company and the emotional connotation associated with the impact, giving rise to more outstanding promotion of social causes.

Our main contribution to this work has been to value positive communication and social marketing to promote better CSR on Twitter. In this sense, it has been verified that there is a relationship between the public's reaction, the affective connotation and the company that issues the messages.

Regret is an undesirable yet very common outcome of social networking site (SNS) use. To date, the literature has examined SNS regret at an aggregate level. The purpose of this paper is to decompose the dimensions and constituents of SNS regret into networking regret and brand page regret, to better understand it, and examine how the two facets of regret are created by SNS use intensity and gratification. The authors also decomposed SNS activities into networking activities and brand page activities and positioned them as predictors of networking regret and brand page regret, respectively.

The authors drew on uses and gratifications theory and positioned interpersonal connectivity and exhibitionism as the antecedents of networking activities as well as informational value and exhibitionism as the antecedents of brand page activities. The authors collected data from 246 Facebook users from France and analyzed the data using the partial least squares approach.

The results show that use intensity has a marginal effect on both brand page and networking regret. However, exhibitionism was found to reinforce the effect of use intensity on both brand page and networking regret. It also had a positive effect on both networking and brand page activities. The other two gratifications, interpersonal connectivity and informational value, had a positive effect on networking and brand page activities, respectively.

To date, empirical attempts at investigating decomposed SNS regret have been rare. The paper fills this theoretical and empirical gap and contributes to the literature on regret in an SNS use context.

The purpose of this paper is to explore the underlying mechanism of how passive social networking site (SNS) use happens from aspects of impression management concern, privacy concern, and SNS fatigue, and then examine whether sense of membership can work as a moderator in this process.

The authors proposed a research model by integrating impression management concern, privacy concern, and SNS fatigue. A total of 301 valid online questionnaires were collected, and these data were assessed by PLS-SEM.

The results show that both impression management concern and privacy concern have direct and positive effects on passive SNS use, and meanwhile they can also indirectly and positively affect passive SNS use through SNS fatigue. Besides, the relationships between impression management concern and its outcomes (SNS fatigue and passive SNS use) can be moderated by sense of membership.

This research is novel in focusing on the formation of passive SNS use and providing new insight into some factors which can trigger users’ passive behaviors in SNS usage. The findings will contribute to SNS literature by offering a well proven conceptual model that facilitates the understanding of passive SNS use.

Natural environments and imagery are known to have a myriad of effects on people’s physical and psychological states. However, little is known about how exposure to nature-related imagery can influence consumers’ motivational states. This research investigates the effect of exposure to nature on consumers’ regulatory focus. More specifically, this paper proposes that consumers exposed to nature will exhibit stronger promotion-oriented focus and weaker prevention-oriented focus, and as such, these consumers will prefer promotion-framed marketing messages over prevention-framed ones. This paper aims to explore a mediating mechanism and a boundary condition for this effect.

A series of six experiments, including an Implicit Association Test, examined the effect of exposure to images of natural objects and scenes (in contrast with non-nature imagery) on consumers’ regulatory focus and whether they experienced regulatory fit when encountering promotion-framed (vs prevention-framed) advertising messages.

The results revealed that consumers exhibited lower prevention-focused and higher promotion-focused motivational orientation after exposure to nature. Furthermore, exposure to nature led consumers to experience more regulatory fit with promotion-oriented marketing messages than prevention-oriented ones. This study found that natural environments offer urban consumers a reprieve from their day-to-day life, which mediates the effect of exposure to nature on regulatory focus. This study investigated the boundary condition of engaging in maintenance of nature (e.g. mow the grass) in which the effects of nature on regulatory focus were attenuated.

This study used text and pictures related to nature as a way to expose the online participants to nature. Future research may use field studies with participants in real natural settings, with expectation of stronger effects. Second, this study examined mostly urban American participants. There may be cultural differences or living situations (e.g. living “off the grid” and in the “wild”) that influence people’s relationship with nature. Future research may examine how these differences can affect the influence of exposure to nature on motivational orientation.

The findings have direct implications for marketing managers and other related stakeholders. Exposing urban consumers to nature – even images of nature – they become more receptive to promotion-framed advertisements and marketing communications (vs prevention-framed messaging).

Little is currently known about how exposure to nature can influence psychological processes such as motivational orientation. This research contributes to the understanding of consumers’ responses to nature-related imagery in advertising and the effect that nature imagery has on consumers’ motivational orientation. This research also contributes to the body of work on regulatory focus by identifying a novel context in which consumers’ motivational orientation can be influenced.
