The purpose of this paper is to develop a multi-agent-based simulation model for the online opinion dissemination during hazardous chemical leakage emergencies into rivers in China, to explore an appropriate crisis information release policy of China’s government for controlling public panic.

In the proposed model, two fundamental attributes of crisis information, i.e., truthfulness (for true or false news) and attitude (for positive, neutral or negative opinion), are considered. Four major agents in the online community system, i.e., citizens, the government, media and opinion leaders, are included. Using four typical accidents of hazardous chemical leakage into rivers in China as case studies, insightful policy implications can be obtained for crisis management and panic control.

The news about the terrible potential damages from such a type of accidents will instantly arise wide-ranging public panic; therefore, the corresponding crisis information release policy should be carefully designed. It is strongly advised against publishing false news to temporarily conceal the accidents, which will seriously hurt the government’s reputation and agitate much larger-scale public panic in terms of degree and duration. To mitigate public panic, the true news especially about treatment measurements should be published immediately. If the government does nothing and releases no crisis information, the public panic will go out of control.

This paper only focuses on the crisis information release policies from the perspectives of the government. Furthermore, this study especially focuses on the cases in China, and extending the proposed model study for general contexts is an important direction to improve this study. Finally, the proposed model should be extended to other types of emergencies to further justify its generalization and universality, especially various natural catastrophes like storms, floods, tsunamis, etc.

This paper develops a multi-agent-based model for online public opinion dissemination in emergency to explore an appropriate crisis information release policy for controlling public panic stemming from hazardous chemicals leakage accidents into rivers. The proposed model makes major contributions to the literature from two perspectives. First, the crisis information about emergency accidents are divided into true and false news based on the truthfulness attribute, and into neutral, positive and negative emotions based on the attitude attribute. Second, the proposed model covers the main agents in the online virtual community.

The purpose of the study is to understand how socially shared misinformation and rumors can enhance the motivation to protect personal interests and enhance social practices of panic buying.

The study employed a number of qualitative data collection methods for the purpose of triangulation, as it can offer thick interpretation and can help to develop a context specific research framework.

The shared misinformation and rumors on social media developed into psychological, physical and social threats; therefore, people started panic buying to avoid these negative consequences. People believed that there were differences between the information shared by politicians and government officials and reality, such as “everything is under control,” whereas social media showed people standing in long queues and struggling to buy the necessities of life. The shared misinformation and rumors on social media became viral and received social validation, which created panic buying in many countries.

It is the responsibility of government, politicians, leaders, media and the public to control misinformation and rumors, as many people were unable to buy groceries due either to socio-economic status or their decisions of late buying, which increased depression among people.

The study merged the theory of rumor (TORT) transmission and protection motivation theory (PMT) to understand how misinformation and rumors shared through social media increased global uncertainty and the desire to panic buy across the world.

There is an assumption in emergency planning that the public will “panic” or refuse to comply in the event of mass decontamination. This assumption has serious implications for how the public will be managed. The paper aims to discuss these issues.

The authors carried out semi-structured interviews with 13 emergency responders, six of whom had experience of incidents involving decontamination. The authors asked them, first, about their experiences of these events and, second, about their expectations for decontamination involving a large crowd. The aim was to explore the extent to which responders perceived non-compliance and anxiety as (crowd) problems during decontamination, and if so, how they felt that they could be addressed.

Responders with experience of decontamination perceived non-compliance and excessive anxiety to be rare, and suggested that orderly behaviour was more common. However, the majority of emergency responders with no experience of decontamination said they expected panic and non-compliance. They therefore emphasised the importance of “controlling”, rather than communicating with, the public.

The authors argue that “control”-based emergency management strategies can impact negatively on the relationship between the public and responders, and hence hinder effective management of an incident. It would therefore be beneficial to provide training for emergency responders on likely public behaviour during incidents involving decontamination.

This research extends previous research by facilitating a detailed understanding of emergency responders’ experiences and perceptions of managing incidents involving decontamination, and showing how these experiences and perceptions can affect the way in which such incidents are managed.

The purpose of this paper was to identify social and behavioral factors responsible for panic buying during global pandemics such as COVID-19.

According to regulatory focus theory, behavior of individuals is regulated by two motivational systems – prevention and promotion. Prevention-focused behavior is motivated by security and safety needs and is associated with a strategic preference for vigilant means of goal pursuit. Prevention-focused vigilance is reflected in unwillingness to take risks and low ability to cope with uncertain environments and changing conditions. Promotion-focused behavior is motivated by growth and self-development needs and is associated with a strategic preference for eager means of goal pursuit. Promotion-focused eagerness is reflected in willingness to take risks and high ability to cope with uncertainty and change. Two studies tested the notion that panic buying during public health crises such as COVID-19 is related to the strength of the prevention system, perceived scarcity of products, perceived threat of the disease, age and gender.

Study 1 showed that the higher the perceived scarcity of products, the higher was the probability that panic buying would set in. Yet, different patterns emerged for men and women. Among women, the stronger the prevention focus, the stronger was the effect. Among men, by contrast, the stronger the prevention focus, the weaker was the effect. Study 2 showed that the higher the perceived threat of the disease, the higher was the probability that panic buying would occur. However, different patterns were observed with age. Among older adults, the stronger the prevention focus, the stronger was the effect. Among young adults, by contrast, the stronger the prevention focus, the weaker was the effect.

Implications to address erratic consumer behavior during future pandemics are discussed.

By applying the theory of regulatory focus to consumer marketing, this research helps to identify marketing strategies to manage panic buying and develop contingency plans that address erratic consumer behavior during future pandemics.

This study aims to the information about consumer product quality and safety that can easily attract public attention and become the focus of public opinion. In recent years, the fast-growing social media have become an import platform for firms for releasing product quality and safety information and for firms and governments to hear public opinion.

To explore how information about consumer product quality and safety gets disseminated and a public opinion is formed in social media, this paper proposes two information transmission models, one with government intervention and the other without government intervention, based on the theory of complex network. A simulation case study in MATLAB is conducted to verify the proposed models.

Information transmission models were constructed, one without government intervention and one with government intervention. The influence of information transmission with government intervention was analyzed. MATLAB was used to simulate the Barabasi and Albert (BA)-based model to consider event information level, government information level and possible panic population proportion. The government intervention effect was evaluated.

Based on a complex network, the derived transmission rule can provide decision-making support for monitoring and managing Web information of consumer product quality and safety.

The intensifying effects of climate change and the growing concentration of population in hazardous locations mean that, for many communities, disasters are increasingly becoming not only foreseeable, but inevitable. While much attention is, and should be, focused on what these foreseeable disasters require in terms of disaster planning and mitigation, attention should also be focused on a related and equally pressing phenomena: mismanagement of disaster response, particularly as climate proves an increasing stressor. Like disasters themselves, disaster mismanagement – while not entirely predictable – may exhibit some predictable patterns. This chapter explores past disaster management failures, considers how climate change may alter or exacerbate certain response pathologies, and evaluates some potential remedies that might mitigate these challenges.

Effective communication has been recognised as an important issue for the management of incidents involving decontamination; evidence shows that failure to communicate effectively may result in increased public anxiety and non‐compliance. This paper aims to examine current provision for communicating with members of the public during decontamination, to facilitate the development of improved responder communication strategies.

To examine the current provision for communicating with members of the public, the authors reviewed open source decontamination guidance documents for responders, as well as published reports of emergency preparedness exercises involving decontamination.

The review of decontamination guidance documents showed that specific guidance for professional responders on how to communicate with the public during incidents that involve decontamination could be improved. Similarly, the review of published decontamination exercises shows that a stronger emphasis on communication with members of the public is needed, in addition to the use of exercises to evaluate the effectiveness of communication strategies.

The present research summarises existing evidence relating to how communication strategies employed by responders can shape public responses to decontamination. Analysed alongside current decontamination guidance for emergency responders, this evidence highlights potential gaps in planning for communicating with members of the public during decontamination. It is hoped that this will promote an increased understanding of the importance of communication during these types of incidents, which will in turn facilitate the development of more comprehensive responder communication strategies.

This chapter examines the conundrum of juvenile immigration law and policy and argues that it is a present-day manifestation of “child-saving” in rhetoric, disposition, and human capital harm. In support of this thesis, the chapter reviews the pertinent human rights, law, and social science evidence, and it concludes that the maintenance of the nation’s existing immigration policy only makes sense within the context of the intentions of the 19th century child-saving movement. To substantiate this view, the political-economic drivers of contemporary US immigration policy (i.e., its child-saving dynamics) are explored. The chapter concludes by speculatively addressing the character (i.e., the form and quality) of modern-day juvenile immigration policy as child-saving informed by the philosophy and criticism of Psychological Jurisprudence (PJ).

COVID-19 disrupted the lives of consumers across the globe, and the retail sector has been one of the hardest hits. The impact of COVID-19 on consumers' retail choice behaviour and retailers' responses has been studied in detail through multiple lenses. Now that the effect of COVID-19 is abating, there is a need to consolidate the learnings during the lifecycle of COVID-19 and set the agenda for research post-COVID-19.

Scopus database was searched to cull out academic papers published between March 2020 and June 6, 2022, using keywords; shopping behaviour, retailing, consumer behaviour, and retail channel choice along with COVID-19 (171 journals, 357 articles). Bibliometric analysis followed by selective content analysis was conducted.

COVID-19 was a black swan event that impacted consumers' psychology, leading to reversible and irreversible changes in retail consumer behaviour worldwide. Research on changes in consumer behaviour and consumption patterns has been mapped to the different stages of the COVID-19 lifecycle. Relevant research questions and potential theoretical lenses have been proposed for further studies.

This paper collates, classifies and organizes the extant research in retail from the onset of the COVID-19 pandemic. It identifies three retail consumption themes: short-term, long-term reversible and long-term irreversible changes. Research agenda related to the retailer and consumer behaviour is identified; for each of the three categories, facilitating the extraction of pertinent research questions for post-COVID-19 studies.

The sudden outbreak of COVID-19 has become a major public health emergency of global concern. Studying the Internet public opinion dissemination mechanism of public health emergencies is of great significance for creating a legalized network environment, and it is also helpful for managers to make scientific decisions when encountering Internet public opinion crisis.

Based on the analysis of the process of spreading the Internet public opinion in major epidemics, a dynamic model of the Internet public opinion spread system was constructed to study the interactive relationship among the public opinion events, network media, netizens and government and the spread of epidemic public opinion. The Shuanghuanglian event in COVID-19 in China was taken as a typical example to make simulation analysis.

Research results show three points: (1) the government credibility plays a decisive role in the spread of Internet public opinion; (2) it is the best time to intervene when Internet public opinion occurred at first time; (3) the management and control of social media are the key to public opinion governance. Besides, specific countermeasures are proposed to assist control of Internet public opinion dissemination.

The epidemic Internet public opinion risk evolution system is a complex nonlinear social system. The system dynamics model is used to carry out research to facilitate the analysis of the Internet public opinion propagation mechanism and explore the interrelationship of various factors.
