Download and read online ebook Social Media in Disaster Response write by Liza Potts. This book was released on 2013-10-30. Social Media in Disaster Response available in PDF, EPUB and Kindle. Social Media in Disaster Response focuses on how emerging social web tools provide researchers and practitioners with new opportunities to address disaster communication and information design for participatory cultures. Both groups, however, currently lack research toolkits for tracing participant networks across systems; there is little understanding of how to design not just for individual social web sites, but how to design across multiple systems. Given the volatile political and ecological climate we are currently living in, the practicality of understanding how people communicate during disasters is important both for those researching solutions and for those putting that research into practice. Social Media in Disaster Response addresses this situation by presenting the results of a large-scale sociotechnical usability study on crisis communication in the vernacular related to recent natural and human-made crisis; this is an analysis of the way social web applications are transformed, by participants, into a critical information infrastructure in moments of crisis. This book provides researchers with methods, tools, and examples for researching and analyzing these communication systems while providing practitioners with design methods and information about these participatory communities to assist them in influencing the design and structure of these communication systems.

Data Mining and Knowledge Discovery for Big Data available in PDF, EPUB and Kindle. The field of data mining has made significant and far-reaching advances over the past three decades. Because of its potential power for solving complex problems, data mining has been successfully applied to diverse areas such as business, engineering, social media, and biological science. Many of these applications search for patterns in complex structural information. In biomedicine for example, modeling complex biological systems requires linking knowledge across many levels of science, from genes to disease. Further, the data characteristics of the problems have also grown from static to dynamic and spatiotemporal, complete to incomplete, and centralized to distributed, and grow in their scope and size (this is known as big data). The effective integration of big data for decision-making also requires privacy preservation. The contributions to this monograph summarize the advances of data mining in the respective fields. This volume consists of nine chapters that address subjects ranging from mining data from opinion, spatiotemporal databases, discriminative subgraph patterns, path knowledge discovery, social media, and privacy issues to the subject of computation reduction via binary matrix factorization.

Download and read online ebook Public Response to Alerts and Warnings Using Social Media write by National Research Council. This book was released on 2013-02-04. Public Response to Alerts and Warnings Using Social Media available in PDF, EPUB and Kindle. Following an earlier NRC workshop on public response to alerts and warnings delivered to mobile devices, a related workshop was held on February 28 and 29, 2012 to look at the role of social media in disaster response. This was one of the first workshops convened to look systematically at the use of social media for alerts and warnings-an event that brought together social science researchers, technologists, emergency management professionals, and other experts on how the public and emergency managers use social media in disasters.In addition to exploring how officials monitor social media, as well as the resulting privacy considerations, the workshop focused on such topics as: what is known about how the public responds to alerts and warnings; the implications of what is known about such public responses for the use of social media to provide alerts and warnings to the public; and approaches to enhancing the situational awareness of emergency managers. Public Response to Alerts and Warnings Using Social Media: Report of a Workshop on Current Knowledge and Research Gaps summarizes presentations made by invited speakers, other remarks by workshop participants, and discussions during parallel breakout sessions. It also points to potential topics for future research, as well as possible areas for future research investment, and it describes some of the challenges facing disaster managers who are seeking to incorporate social media into regular practice.

Download and read online ebook Media and Disaster Risk Reduction write by Rajib Shaw. This book was released on 2021-03-16. Media and Disaster Risk Reduction available in PDF, EPUB and Kindle. This book analyzes recent advances, trends, challenges and potentials of the role of media in disaster risk reduction. Collaboration, co-design and co-delivery with other stakeholders in science technology, private sectors, and civil society are found to be effective in reaching people and communities. The media is considered to be of utmost importance in all phases of disasters, before, during and after, with different types of media having different proactive roles to play in disaster risk reduction. Before disasters, they play essential roles not only in bringing early warning to people but also in enhancing their perception of the need to take action. At during- and post-disaster response recovery phases, community radio and social media are the key. These necessitate a resilient media infrastructure as the core of uninterrupted coverage. Media literacy has become an important issue for several stakeholders, including governments. In addition, more focus is placed on media governance to look at the priorities of disaster risk reduction initiatives within the media. All of these are considered to lead to trust in the media, which further improves people’s disaster response actions based on information from the media, before and during disasters. Covering different aspects of media, this book is a valuable source for students, researchers, academics, policy-makers and development practitioners.
