This article considers whether thinking about journalism's present set of challenges is best served by the notion of “crisis.” It argues that adopting such a notion to explain a diverse set of technological, political, economic, social, occupational, moral, and legal circumstances misses an opportunity to recognize how contingent and differentiated the futures of journalism might be. It also raises critical questions about how institutions deal with uncertainty at their core, obscuring a fuller understanding of the permutations that get eclipsed by perceiving crisis as a unitary phenomenon. 相似文献

Social media has introduced a key ingredient, and a potentially unfamiliar variable, into the practice of crisis communication. In this paper, the authors critically assess the social media milestones related to Hurricane Sandy according to situational crisis communication theory (SCCT) (Coombs, 2007). Further, we discuss the crisis lifecycle of Hurricane Sandy with regard to the potential implementation of the STREMII model of social media crisis management, a proposed model originated through this research application. This original model develops from lessons and best practices discovered in historical and contemporary cases of social media crises and crisis management. The researchers acknowledge potential limitations and describe steps for further development of the model through research, all the while recognizing the powerful and paradoxical role of social media in the crisis management process. In reflection of Hurricane Sandy, further qualitative and quantitative examinations of crisis events are encouraged to evaluate the STREMII model continually in the dynamic social media climate and across the vast facets of crisis communication. 相似文献

Sentiment analysis techniques are increasingly used to grasp reactions from social media users to unexpected and potentially stressful social events. This paper argues that, alongside assessments of the affective valence of social media content as negative or positive, there is a need for a deeper understanding of the context in which reactions are expressed and the specific functions that users' emotional states may reflect. To demonstrate this, we present a qualitative analysis of affective expressions on Twitter collected in Germany during the 2011 EHEC food contamination incident based on a coding scheme developed from Skinner et al.'s (2003) coping classification framework. Affective expressions of coping were found to be diverse not only in terms of valence but also in the adaptive functions they served: beyond the positive or negative tone, some people perceived the outbreak as a threat while others as a challenge to cope with. We discuss how this qualitative sentiment analysis can allow a better understanding of the way the overall situation is perceived – threat or challenge – and the resources that individuals experience having to cope with emerging demands. 相似文献

Online networks using Web 2.0 technologies have proven useful for communication among all parties involved in managing crises. These networks rapidly disseminate information allowing for coordination among organizations responding to the needs of those whose safety and wellbeing are threatened by the crisis and its aftermath. This study provides a network analysis of official Twitter accounts activated during the Charleston, West Virginia, water contamination crisis in 2014. The city’s water supply was rendered unfit for drinking or bathing after 7500 gallons of a toxic chemical leaked into the Elk River. The network created by the 41 Twitter accounts associated with the West Virginia water contamination lacked density, contained several isolates, exchanged information quickly (geodesic distance diameter), and contained both national and local accounts. The lack of density indicates limited exchange of information, particularly between national and federal accounts. The rapid dissemination of the information that was shared and the fact that some accounts did bridge the local and national gap, however, show the positive potential for such networks in responding to crises. 相似文献

Many efforts in the area of computer security have been drawn to attribute-based access control (ABAC). Compared to other adopted models, ABAC provides more granularity, scalability, and flexibility. This makes it a valuable access control system candidate for securing platforms and environments used for coordination and cooperation among organizations and communities, especially over open networks such as the Internet. On the other hand, the basic ABAC model lacks provisions for context, trust and privacy issues, all of which are becoming increasingly critical, particularly in high performance distributed collaboration environments. This paper presents an extended access control model based on attributes associated with objects and subjects. It incorporates trust and privacy issues in order to make access control decisions sensitive to the cross-organizational collaboration context. Several aspects of the proposed model are implemented and illustrated by a case study that shows realistic ABAC policies in the domain of distributed multiple organizations crisis management systems. Furthermore, the paper shows a collaborative graphical tool that enables the actors in the emergency management system to make better decisions. The prototype shows how it guarantees the privacy of object’s attributes, taking into account the trust of the subjects. This tool incorporates a decision engine that relies on attribute based policies and dynamic trust and privacy evaluation. The resulting platform demonstrates the integration of the ABAC model, the evolving context, and the attributes of actors and resources. 相似文献

In this paper we build a multi-theoretical and multi-level framework for analyzing Global Crisis Networks (GCN). These information-centric, heterarchically structured networks are instantiated in response to major disasters with global impact. The instantiation of GCN is conceived as a problem of collective action. Its success depends on multi-level preparedness, and network orchestration and participation. With this framework we analyze the SARS outbreak in 2002 and its successful containment in 2003. We analyze two individual country cases, Canada and China and discuss the role of the network orchestrator, the World Health Organizations. The paper concludes with implications for research and practice. 相似文献
