Following a series of natural disasters, including Hurricane Katrina, that revealed shortcomings in the nation's ability to effectively alert populations at risk, Congress passed the Warning, Alert, and Response Network (WARN) Act in 2006. Today, new technologies such as smart phones and social media platforms offer new ways to communicate with the public, and the information ecosystem is much broader, including additional official channels, such as government social media accounts, opt-in short message service (SMS)-based alerting systems, and reverse 911 systems; less official channels, such as main stream media outlets and weather applications on connected devices; and unofficial channels, such as first person reports via social media. Traditional media have also taken advantage of these new tools, including their own mobile applications to extend their reach of beyond broadcast radio, television, and cable. Furthermore, private companies have begun to take advantage of the large amounts of data about users they possess to detect events and provide alerts and warnings and other hazard-related information to their users. More than 60 years of research on the public response to alerts and warnings has yielded many insights about how people respond to information that they are at risk and the circumstances under which they are most likely to take appropriate protective action. Some, but not all, of these results have been used to inform the design and operation of alert and warning systems, and new insights continue to emerge. Emergency Alert and Warning Systems reviews the results of past research, considers new possibilities for realizing more effective alert and warning systems, explores how a more effective national alert and warning system might be created and some of the gaps in our present knowledge, and sets forth a research agenda to advance the nation's alert and warning capabilities.

This book describes in detail disaster management principles with applications through software and early warning systems. The aim is to introduce the concept of advanced technology for disaster management. Hence, it starts with a basic introduction and the types of disasters this technology will address. It then examines these functions by taking into account various factors vulnerable to disaster losses. Finally, the results are discussed with the aid of software: OPNET and SAHANA Disaster Management Tool. The application of sensor systems to manage a disaster is also extensively discussed. Features Introduces the concept of disaster management from the perspective of application of advanced technologies for disaster management Provides an overview of applied electronics for disaster applications Examines the role of efficient and robust Information and Communication Technology (ICT) systems for reduction of response time and for augmenting meaningful usage of resources during the disaster management phases of relief, response, recovery and rehabilitation

Since the dawn of medical science, people have recognized connections between a change in the weather and the appearance of epidemic disease. With today's technology, some hope that it will be possible to build models for predicting the emergence and spread of many infectious diseases based on climate and weather forecasts. However, separating the effects of climate from other effects presents a tremendous scientific challenge. Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" And perhaps the most important question of all: Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world? Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages. The book also examines the potential for using climate forecasts and ecological observations to help predict infectious disease outbreaks, identifies the necessary components for an epidemic early warning system, and reviews lessons learned from the use of climate forecasts in other realms of human activity.

The book provides information on the major EEW systems in operation and on the state-of-the-art of the different blocks forming an EW system: the rapid detection and estimation of the earthquake’s focal parameters, the signal transmission, the engineering interface and the information reliability/false alarm problem. It is the first time that so many aspects of EEW systems have been specifically focused upon within a single book.

Presenting the results of an ambitious research activity this book intends to understand why Early Warning Systems (EWSs) fail. However, from the beginning, the objective turned out to be challenging; first, because, so far, there is not a shared understanding of what an EWS is (among both researchers and practitioners communities); second, as a consequence, because it is equally unclear when an EWS can be considered successful or not. Due to this, the research needed first to face some “open questions” instead of going straight to the point under investigation. Specifically, it was first necessary to define EWS, identify its components and functions, peculiarities, and weak points. Only at that point, a first attempt to evaluate EWS performance was possible. Flood Early Warning Systems Performance is organised according to the conceptual steps required by the research. In part I the “open questions” about the definition and the role of EWSs are handled, the aim being the identification of how to evaluate their effectiveness/performance. Part II focuses on the real aim of the research, providing concepts and tools to assess EWS performance; suggested tools are also implemented in a case study to describe how they can be applied in practice. Focusing specifically on the topic of flood risk in mountainous regions, the book can be viewed as a sort of manual for EWS designers, managers, and users. It is organised into different independent sections which will appeal both to experts as well as those with an interest in the subject. Most of results can also be exported to other hazards.

Online learning has increasingly been viewed as a possible way to remove barriers associated with traditional face-to-face teaching, such as overcrowded classrooms and shortage of certified teachers. While online learning has been recognized as a possible approach to deliver more desirable learning outcomes, close to half of online students drop out as a result of student-related, course-related, and out-of-school-related factors (e.g., poor self-regulation; ineffective teacher-student, student-student, and platform-student interactions; low household income). Many educators have expressed concern over students who unexpectedly begin to struggle and appear to fall off track without apparent reason. A well-implemented early warning system, therefore, can help educators identify students at risk of dropping out and assign and monitor interventions to keep them on track for graduation. Despite the popularity of early warning systems, research on their design and implementation is sparse. Early Warning Systems and Targeted Interventions for Student Success in Online Courses is a cutting-edge research publication that examines current theoretical frameworks, research projects, and empirical studies related to the design, implementation, and evaluation of early warning systems and targeted interventions and discusses their implications for policy and practice. Moreover, this book will review common challenges of early warning systems and dashboard design and will explore design principles and data visualization tools to make data more understandable and, therefore, more actionable. Highlighting a range of topics such as curriculum design, game-based learning, and learning support, it is ideal for academicians, policymakers, administrators, researchers, education professionals, instructional designers, data analysts, and students.
