Abstract
This paper introduces a macro traffic flow model of carbon dioxide emissions from container ports. As long as both the throughput and the transshipment rate of the port are available, any port in the world can use it to estimate emissions. Initially, two Japanese container ports are used as reference points to derive the equivalent units of carbon dioxide per TEU for application to other ports. Then macro traffic flows within a container port are defined. Finally, carbon dioxide emissions from different container ports are estimated using the macro estimation procedure introduced in this paper. The results of trial estimations for selected ports among different countries highlight that the impacts of container ports on global warming are serious. This issue will be intensified if competition is increased by the larger container ports aspiring to be international mega hubs.

Abstract
Purpose
The current paper is a brief review of the emerging field of quantum-like modelling in game theory. This paper aims to explore several quantum games, which are superior compared to their classical counterparts, which means either they give rise to superior Nash equilibria or they make the game fairer. For example, quantum Prisoners Dilemma generates Pareto superior outcomes as compared to defection outcome in the famous classical case. Again, a quantum-like version of cards game can make the game fairer, increasing the chance of winning of players who are disadvantaged in the classical case. This paper explores all the virtues of simple quantum games, also highlighting some findings of the authors as regards Prisoners Dilemma game.
Design/methodology/approach
As this is a general review paper, the authors have not demonstrated any specific mathematical method, rather explored the well-known quantum probability framework, used for designing quantum games. They have a short appendix which explores basic structure of Hilbert space representation of human decision-making.
Findings
Along with the review of the extant literature, the authors have also highlighted some new findings for quantum Prisoners Dilemma game. Specifically, they have shown in the earlier studies (which are referred to here) that a pure quantum entanglement set up is not needed for designing better games, even a weaker condition, which is classical entanglement is sufficient for producing Pareto improved outcomes.
Research limitations/implications
Theoretical research, with findings and implications for future game designs, it has been argued that it is not always needed to have true quantum entanglement for superior Nash Equilibria.
Originality/value
The main purpose here is to raise awareness mainly in the social science community about the possible applications of quantum-like game theory paradigm. The findings related to Prisoners Dilemma game are, however, original.

Abstract
This paper has presented a brief description of the SSS industry in Europe and has discussed what is meant by this industry, what types of ships are involved, what cargoes are carried, what are the main geographical areas of operations, what are the industry's strengths and weaknesses, and what users require from the industry before it can become a realistic choice for many in multimodallogistics transport chains.

Abstract
This paper defines the emerging intermodal issues, identifies alternative solutions and develops strategies to achieve them. It reviews intermodal logistics policies in the EU, NAFTA and Asia, focusing on the United States and Japan in NAFTA and Asia respectively, because they have been the prominent motors of international trade in their regions. From an Asian standpoint, it is a pity that it is not yet possible to report on a common intermodal strategy.

Abstract
Purpose
This paper aims to propose an integration of the analytic hierarchy process (AHP) and data envelopment analysis (DEA) methods in a multiattribute grey relational analysis (GRA) methodology in which the attribute weights are completely unknown and the attribute values take the form of fuzzy numbers.
Design/methodology/approach
This research has been organized to proceed along the following steps: computing the grey relational coefficients for alternatives with respect to each attribute using a fuzzy GRA methodology. Grey relational coefficients provide the required (output) data for additive DEA models; computing the priority weights of attributes using the AHP method to impose weight bounds on attribute weights in additive DEA models; computing grey relational grades using a pair of additive DEA models to assess the performance of each alternative from the optimistic and pessimistic perspectives; and combining the optimistic and pessimistic grey relational grades using a compromise grade to assess the overall performance of each alternative.
Findings
The proposed approach provides a more reasonable and encompassing measure of performance, based on which the overall ranking position of alternatives is obtained. An illustrated example of a nuclear waste dump site selection is used to highlight the usefulness of the proposed approach.
Originality/value
This research is a step forward to overcome the current shortcomings in the weighting schemes of attributes in a fuzzy multiattribute GRA methodology.

Abstract
Purpose
Sports leagues have stood out in the entertainment industry due to their great economic value and cultural impact. This is the case of the American sports leagues, with emphasis on the National Basketball Association (NBA), whose largest Latin American market lies on Brazil. The aforementioned league’s audience is constantly growing, a fact that can be partially explained by the encouragement provided for its viewers to interact through social media, in a phenomenon called social TV. Accordingly, the aim of the present study is to investigate how social TV works as a means for Brazilian fans to coproduce their NBA broadcasting enjoyment through social media interactions.
Design/methodology/approach
The authors conducted a netnography on the community of fans engaged in Twitter hashtag #NBAnaESPN, which was released by ESPN to promote audience integration during NBA games' broadcasting.
Findings
A theorization about the role played by social TV in the way fan culture articulates through social media to enjoy broadcasting media products was herein presented. The findings of this study have evidenced three categories concerning the role played by television broadcasting, social media and the fandom in NBA consumption by Brazilian fans. Based on these findings, the authors got to the conclusion that social TV establishes a mediatized environment where fan culture can be articulated through social media to enable interactions about television broadcasting.
Research limitations/implications
The study was limited to members of the Brazilian NBA audience who engage in the official social media of the league’s broadcasting.
Originality/value
The study heads toward a theoretical generalization based on the research results.

Abstract
Purpose
Recognising the growing importance of environmental and sustainable activities and the role of communication strategies in soliciting their financing, this work investigates the influence of message framing, green emphasis and quantitative information on the probability of green crowdfunding campaigns' success.
Design/methodology/approach
This analysis is based on crowdfunding campaigns published between 2015 and 2020 on the Indiegogo platform in the category “Community projects – Environment”. The study develops an in-depth qualitative content analysis of the projects before performing an empirical examination to determine funding causes.
Findings
Communication strategies (message framing, green emphasis and quantitative goals) affect funding success. However, project category moderates the impact of message framing and green emphasis on campaign success. While positive framing increases agri-food campaign success, negative framing is more effective for clean energy and climate preservation projects. Moreover, indication of a quantitative goal and a marked green emphasis in a project's presentation increase campaign success, but a too marked green emphasis is only effective for agri-food projects.
Practical implications
Green entrepreneurs and campaign managers must work carefully on their projects' communication, accounting for the type of product proposed, emphasising green components in its description and utilising quantitative information to present future goals. These strategies maximise backers' responses and enable entrepreneurs to obtain funding. The authors’ findings may be extended to other contexts, including the banking sector, to craft effective communication strategies for green financial products.
Originality/value
By applying framing theory in a new context (i.e. the online financing of green entrepreneurs), this study identifies new campaign success determinants and provides evidence for the moderating role of project category. Furthermore, the study highlights the need to develop different communication strategies for social and environmental-oriented projects.

Abstract
COVID-19 is bringing hardship and tragedy. Health workers are having to take appalling risks; loved ones are being lost; lockdown is causing great distress. And, as always in testing times, the disadvantaged are being hit worst. As we emerge from the shadows, the call from the vested interests, from the systems current winners, will be for a rapid return to business as usual. We must resist this; business as usual got us into this mess.
COVID-19 is trying to tell us something; we health educators and social marketers must listen, think and, above all, take action.

Abstract
Purpose
Stakeholder capitalism (SC) advocates that organisations should focus on creating long-term value for all key stakeholders rather than maximising short-term profits for shareholders. This paper aims to explore whether and how business organisations have applied stakeholder capitalism principles (SCPs) during the COVID-19 pandemic and how these efforts were communicated in integrated reports.
Design/methodology/approach
This study is based on the content analysis of the text extracted from the integrated reports of 22 companies categorised as excellent in the 2020 EY Excellence in Integrated Reporting Award 2020. The research material consisted of paragraphs that reflected how the company observed the SCPs in practice.
Findings
The stakeholder responsibility principle was the most represented by the examined companies, followed by the principles of continuous creation, stakeholder engagement and stakeholder cooperation. The COVID-19 pandemic has propelled the necessity of implementing innovative solutions to counteract the virus's spread. It has also spurred the need for two-way digitalised communication between the executives and stakeholders. The new situation also required collaborative approaches in the forms of partnerships, joint initiatives and programmes to ensure employee safety and help communities recover from the social and economic impacts of the pandemic.
Originality/value
This study links SC with integrated reporting (IR) and contributes to the literature by providing new insights into how SCPs have been applied during the COVID-19 pandemic. This discussion suggests that whereas these principles determine how the companies must act to satisfy stakeholders expectations, integrating reporting may help develop a report that is stakeholder-oriented and which responds to their information needs.
