Abstract: This research explores the potential determinants of trust in newly formed virtual teams to better inform the choice of communication media for virtual emergency response groups for which interpersonal trust is crucial. Results of a laboratory experiment indicate that the way that communicants view their teammates and themselves as part of that team is significantly correlated with the level of trust that they experience. Impression formation, public self-awareness, perceived social presence, and self-disclosure are all found to have significant correlations with trust among ad hoc teammates. It is therefore recommended that the design of emergency response communication systems include features to foster these feelings thereby promoting trust among teammates. Our results are applicable to ad hoc emergency teams who interact for a period of time to address relief and recovery efforts after a major disaster or emergency.

Abstract: Emergency managers receive communication training about the importance of being ?first, right and credible?,
which is not easy. For instance, in October 2018, the Aude department in the South-West of France was hit by
intense rain. Flash floods were hard to forecast and only the ?orange? level of vigilance could be raised initially, but
the population dismissed this very usual warning in that season. The ?red? level was then raised too late, leading
to high criticism. The main problem here is the loss of trust induced by too many ?false alarms?. In this paper
we propose a serious game called VigiFlood for raising awareness in the population about the difficulty of crisis
communication and their own responsibility for reacting to the alerts. The implemented game still has limited
functionality but already shows interesting results in helping the user to visualise and understand the trust dynamics

Abstract: This paper describes our approach to facilitating automated data sharing during a crisis management scenario. There are a number of reasons why this is difficult, of which we are addressing two of the main ones. Firstly, data in different organisations (and organisations) is mismatched in that different terminology, structure, specificity and data formats are used, so automated comprehension of data is problematic. Secondly, is that it is hard to assess the trustworthiness of data from other organisations. We have developed data-matching and provenance-based solutions to these problems individually. In this paper, we discuss how best these approaches can be integrated so that decision makers can quickly and automatically be presented with data to match, or approximately match, their data needs, together with the right information for them to understand the quality and meaning of this data, and introduce the CEM-DIT (Communication for Emergency Management through Data Integration and Trust) system.

Abstract: Even though the adoption of emergency alerting systems may improve the safety and security of individuals, participation in existing systems that utilize mobile alerting in universities in USA varies and does not match the high adoption rate of mobile phone technology itself (Sullivan, Häkkinen & Piechocinski 2009; Wu, 2009). As the adoption of mobile alerting system (MAS) can be viewed as a critical life safety benefit, there is motivation to better understand factors that affect the acceptance of MAS. Among the possible, alternative methods of implementing mobile alerting, an opt-in type of system can enable the alerting process to be executed in a way that is more suitable and useful for a diverse community of individuals. As a result of this study, a refined version of technology acceptance model (TAM) is proposed, extended with factors of perceived trust and perceived financial cost to better interpret the acceptance of MAS. This model is being evaluated in ongoing research on MAS in a university and community context.

Abstract: An important aspect of working in an emergency operations center (EOC) is determining what information is credible and what actions to take based on that information. Information during an emergency may come from various sources and EOC workers may not know the information providers personally. Information may come from electronic sources where the exact source of the information may be unknown and credibility may be affected. For this study, we conducted ethnographic interviews with emergency management subject matter experts to gain insights on credibility. The interviews included a series of questions to learn about the current processes of an EOC, what sources generally provide information about the situation and what factors determine credibility. These interviews are ongoing and this paper provides a summary of the interviews completed at this point. The expected outcome of this study is a potential software system with features to enhance credibility despite weak source information.

Abstract: As one of the most well-known social media platforms in China, Weibo provides an online public sphere. During the 2018 Shouguang flood, many people who were affected converged on the platform to discuss the disaster. The government ? the highest emergency management authority ? was accused of using censorship and other measures to suppress the coverage of the disaster. Based on an analysis of 34 qualitative interviews with Weibo users, of which nine directly address the Shouguang floods, this paper examines how three major actors contested facts and responsibilities during the disaster. Focusing on the state-censored, market-moderated social media context in China, our ongoing study provides new insights into a universal challenge of managing diverging interpretations and expectations in risk communication. We show that the establishing and framing of facts is inherently ethical and political. Time, time-space compression, liability and scales of risk responsibility emerge as critical points of friction. We draw on theories of risk governance, public discourse, computer supported collaborative work, and media studies for analysis and to articulate avenues for design.

Abstract: Effective response to emergency, security and operational continuity events generally requires cooperation across political, physical and technical boundaries. It's necessary, therefore, to use a communications system that enables people in heterogeneous organization to communicate effectively. Since 2002, Swan Island Networks has been developing an Internet-based information sharing system that links responsible people with the information necessary to make better decisions, and to each other. The system allows people to form “Communities of Trust”, in which all community members are known and authenticated. Each community is formed by a responsible Champion, who determines who can participate and what information will be shared within the community. In order for people to be willing to share, and to accept the information they receive as genuine, the community must operate in an environment of trust. This presentation outlines the fundamental concepts, methodologies and features for access and information control that create a trusted environment, particularly Authorization, Authentication and Audit (AAA). In the system discussed, AAA elements function together to create a comprehensive trust framework, and provide a contextually appropriate level of information assurance, data protection and dissemination control.

Abstract: Improving the survival rate of Out-of-Hospital Cardiac Arrest (OHCA) remains an important public health issue. Indeed, current survival rates are approximately 10% and can be significantly enhanced by early Cardiopulmonary reanimation (CPR) and early defibrillation. Bystanders are most likely to perform these acts, but few resources (such as digital apps) are dedicated to them due to a lack of confidence in their abilities from them and from the professionals. In order to build trust and collaboration between the dispatchers and the bystanders, an OHCA simulation workshop was conducted involving the whole survival chain. The main idea consisted in getting the participants to interact via an application dedicated to bystanders which provided a CPR demonstration video. The aim was to analyze the effects of this video on the CPR itself and especially on the lived-experience of the participants. A further objective was to assess how the shared workshop would affect the relationship between the stakeholders.

Abstract: Individual situational awareness (SA) is crucial for building team SA, which is necessary for achieving a shared understanding of a situation, making informed decisions, and taking appropriate actions. This article examines the communication barriers that emerge when transitioning from individual to team SA in emergency management scenarios. We observed two emergency exercises on “ongoing life-threatening violence” and dam failure causing hospital congestion. The study was complemented with interviews with participants of these exercises, aiming at identifying barriers called SA-demons in the team setting. We discovered barriers that hinder the establishment of team SA, including a vicious cycle of mistrust, a fragmented information trap, a false feeling of mastery trap, and a decaying memory trap. These barriers can stem from individual, organizational, or technological factors. To complement existing SA theories, we applied the Cynefin framework and found that standard operating procedures can be potential barriers when transitioning into chaotic or complex domains.

Abstract: To this date, research on crisis informatics has focused on the detection of trust in Twitter data through the use of message structure, sentiment, propagation and author. Little research has examined the effects of perceived emotion of these messages in the crisis response domain. Toward detecting useful messages in case of crisis, we examine perceived emotions of these messages and how the different emotions affect the perceived usefulness and trustworthiness. Our analysis is carried out on two datasets gathered from Twitter concerning hurricane Sandy in 2012 and the Boston Bombing 2013. The results indicate that there is a significant difference in the perceived emotions that contribute towards the perceived trustworthiness and usefulness. This could have impacts on how messages from social media data are analyzed for use in crisis response.

Abstract: Social media data, such as Twitter, enables crisis response personnel and civilians to share information during a crisis situation. However, a lack of information gatekeeping processes also translates into concerns about both content and source credibility. This research aims to identify Twitter metrics which could assist with the latter. A 2 (average number of hashtags used) x 2 (ratio of tweets/retweets posted) x 2 (ratio of follower/followee) between-subjects experiment was conducted to evaluate the level of influence of Twitter broker metrics on behavioral intention and the perception of source credibility. The findings indicate that follower/followee ratio in conjunction with hashtag usage approached a significant effect on perceived source credibility. In addition, both Twitter awareness metrics and dispositional trust played an important role in determining behavioral intentions and perceived source credibility. Implications and limitations are also discussed.

Abstract: We report on the social media communications and work practices of the Jefferson County Type III Incident Management Team during the September 2013 Colorado Floods. In this case study, we examine flood-related communications across three platforms: Facebook, Twitter, and the team's blog for insight into how this innovative team coordinated their communications to meet the information needs of a community outside of the media spotlight. Using a mixed method approach of interviews and social media content analysis, we describe their online behaviors in relation to the needs of the emergency response as a whole. We report on adaptations to their work practice that allowed them to extend traditional communications with social media to create an integrated communication plan. Finally, we look to the team's experiences for direction in how to use social media in emergencies generally.
