This book was released on 2010 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diffusion of influenza disease and that of individual preventive behavior are intrinsically interrelated. This dissertation presents an original dual-diffusion model to couple these two diffusion processes together. At the conceptual level, the model is composed of four components, including the contact network, diffusion of influenza, diffusion of preventive behavior, and the interaction between the two diffusion processes. The individual-based approach, network structure, disease model and threshold adoption model have been integrated under this framework to formulate each component. The model implementation is carried out in the urbanized area of Buffalo, New York, based on census data, land use data, travel statistics, and health behavior survey.^The dual-diffusion model successfully replicates the observed trends of influenza infection and antiviral-drug use, and offers a close representation of the lab-confirmed data as well. The presented model is further used to investigate spatial-temporal dynamics of the dual-diffusion processes. The simulation results identify five subsequent stages during the course of dual-diffusion, including: the local growth, expansion, fast city-wide growth, slow city-wide growth, and fade-out. Two major factors are found to contribute to the dynamics. One is the spatial heterogeneity in the city, in terms of the population distribution and land use patterns. This factor directly influences the spatial layout of the dual-diffusion. The other factor is the travel of individuals in the city, which has profound effects on the temporal sequence of the dual-diffusion. One purpose of developing the dual-diffusion model is to explore effective strategies for influenza control and prevention.^This research evaluates the combined effectiveness of control strategies and individual preventive behavior. Three control strategies and their combination have been simulated, including a targeted antiviral prophylaxis (TAP) strategy, a workplace closure strategy, and a travel restriction strategy. The results suggest that previous studies on control strategies may have under-estimated the resultant effectiveness, because the effects of preventive behavior are overlooked. The addition of preventive behavior may double, or even triple, the control effectiveness, leading to smaller disease attack rates and lower epidemic peaks.^The control strategies previously suggested might be resource-intensive, and optimized strategies are recommended. In addition to the control strategies, two preventive strategies have been simulated and assessed: one strategy offers free antiviral drugs to households (referred to as incentive strategy), and the other establishes role models of adoption at affected workplaces (called role-model strategy). Different from previous studies, the assessment not only considers the effects of these strategies on the number of adoptions, but also their effects on the number of infections. The results show that the incentive strategy can be effective to control influenza, given a moderate compliance of households. The role-model strategy is not recommended for the study area, because half of the population may be reluctant to adopt unless they were ill, even if role models are setting around them.^This dissertation expands current epidemic models into a new field, human preventive behavior against diseases. It argues that the interactions between human and disease are reciprocal, and the failure to consider either side may affect decision making. The results offer in-depth understandings in influenza transmission, and control, and prevention. A number of strategies explored in this research can be valuable for the public to overcome socio-economic challenges posed by future influenza epidemics.

Book excerpt: Major influenza pandemics pose a constant threat. As evidenced by recent H5N1 avian flu and novel H1N1, influenza outbreaks can come in close succession, yet differ in their transmission and impact. With accelerated levels of commercial and population mobility, new forms of flu virus can also spread across the globe with unprecedented speed. Responding quickly and adequately to each outbreak becomes imperative on the part of governments and global public health organizations, but the difficulties of doing so are legion. One tool for pandemic planning is analysis of responses to past pandemics that provide insight into productive ways forward.This book investigates past influenza pandemics in light of today's, so as to afford critical insights into possible transmission patterns, experiences, mistakes, and interventions. It explores several pandemics over the past century, from the infamous 1918 Spanish Influenza, the avian flu epidemic of 2003, and the novel H1N1 pandemic of 2009, to lesser-known outbreaks such as the 1889-90 influenza pandemic and the Hong Kong Flu of 1968. Contributors to the volume examine cases from a wide range of disciplines, including history, sociology, epidemiology, virology, geography, and public health, identifying patterns that cut across pandemics in order to guide contemporary responses to infectious outbreaks.
Download or read book Britain and the 1918 19 Influenza Pandemic written by Niall Johnson and published by Routledge. This book was released on 2006-09-27 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between August 1918 and March 1919 a flu pandemic spread across the globe and in just under a year 40 million people had died from the virus worldwide. This is the first book to provide a total history and seriously analyze the British experiences during that time. The book provides the most up-to-date tally of the pandemic’s impact, including the vast mortality, as well as questioning the apparent origins of the pandemic. A ‘total’ history, this book ranges from the spread of the 1918–1919 pandemic, to the basic biology of influenza, and how epidemics and pandemics are possible, to consider the demographic, social, economic and political impacts of such a massive pandemic, including the cultural dimensions of naming, blame, metaphors, memory, the media, art and literature. An inter-disciplinary study, it stretches from history and geography through to medicine in order to convey the full magnitude of the first global medical ‘disaster’ of the twentieth century, and looks ahead to possible pandemics of the future. Niall Johnson brings an impressive scholarly eye on this fascinating and highly relevant topic making this essential reading for historians and those with an interest in British and medical history.
Download or read book Pale Rider written by Laura Spinney and published by PublicAffairs. This book was released on 2017-09-12 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1918, the Italian-Americans of New York, the Yupik of Alaska, and the Persians of Mashed had almost nothing in common except for a virus -- one that triggered the worst pandemic of modern times and had a decisive effect on twentieth-century history. The Spanish flu of 1918-1920 was one of the greatest human disasters of all time. It infected a third of the people on Earth -- from the poorest immigrants of New York City to the king of Spain, Franz Kafka, Mahatma Gandhi, and Woodrow Wilson. But despite a death toll of between 50 and 100 million people, it exists in our memory as an afterthought to World War I. In this gripping narrative history, Laura Spinney traces the overlooked pandemic to reveal how the virus travelled across the globe, exposing mankind's vulnerability and putting our ingenuity to the test. As socially significant as both world wars, the Spanish flu dramatically disrupted -- and often permanently altered -- global politics, race relations and family structures, while spurring innovation in medicine, religion and the arts. It was partly responsible, Spinney argues, for pushing India to independence, South Africa to apartheid, and Switzerland to the brink of civil war. It also created the true "lost generation." Drawing on the latest research in history, virology, epidemiology, psychology and economics, Pale Rider masterfully recounts the little-known catastrophe that forever changed humanity.
Download or read book The Transmission of Epidemic Influenza written by R.E. Hope-Simpson and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE PLAGUE YEARS Mankind has always been fascinated by "origins," and biologists are no exception. Darwin is our most famous example. What is the origin of mankind, of species, of infectious diseases? In the last few years we have seen the emergence and spread of some apparently "new" viruses, such as HIV -1 and the virus causing bovine spongiform encephalomyelopathy. But are these, in fact, entirely new agents, or mutated forms of "old" viruses that have evolved along with us for eons? Edgar Hope-Simpson could not have written this book at a more opportune moment. He is a firm believer in gradual evolution, rather than the sudden arrival of new agents. I suspect that he would also have a naturalist's Darwinian approach for the origin of AIDS. It has been a source of some amazement to me over the years how even the most innovative scientists conform to a current hypothesis. Pioneer thinking comes more easily to persons outside the scientific mainstream. Edgar Hope Simpson has always struck me as a modem-day naturalist of the classic style, observant and perhaps a little maverick in line of thought. Certainly, the central hypothesis propounded in this book will be controversial to many scientists. From his unique citadel, the Epidemiological Research Unit in Cirencester, he has carefully reexamined mortality data from old records as well as new.

Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years have seen a major paradigm shift in the field of violence prevention, from the assumption that violence is inevitable to the recognition that violence is preventable. Part of this shift has occurred in thinking about why violence occurs, and where intervention points might lie. In exploring the occurrence of violence, researchers have recognized the tendency for violent acts to cluster, to spread from place to place, and to mutate from one type to another. Furthermore, violent acts are often preceded or followed by other violent acts. In the field of public health, such a process has also been seen in the infectious disease model, in which an agent or vector initiates a specific biological pathway leading to symptoms of disease and infectivity. The agent transmits from individual to individual, and levels of the disease in the population above the baseline constitute an epidemic. Although violence does not have a readily observable biological agent as an initiator, it can follow similar epidemiological pathways. On April 30-May 1, 2012, the Institute of Medicine (IOM) Forum on Global Violence Prevention convened a workshop to explore the contagious nature of violence. Part of the Forum's mandate is to engage in multisectoral, multidirectional dialogue that explores crosscutting, evidence-based approaches to violence prevention, and the Forum has convened four workshops to this point exploring various elements of violence prevention. The workshops are designed to examine such approaches from multiple perspectives and at multiple levels of society. In particular, the workshop on the contagion of violence focused on exploring the epidemiology of the contagion, describing possible processes and mechanisms by which violence is transmitted, examining how contextual factors mitigate or exacerbate the issue. Contagion of Violence: Workshop Summary covers the major topics that arose during the 2-day workshop. It is organized by important elements of the infectious disease model so as to present the contagion of violence in a larger context and in a more compelling and comprehensive way.
Download or read book Viral Molecular Machines written by Michael G. Rossmann and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will contain a series of solicited chapters that concern with the molecular machines required by viruses to perform various essential functions of virus life cycle. The first three chapters (Introduction, Molecular Machines and Virus Architecture) introduce the reader to the best known molecular machines and to the structure of viruses. The remainder of the book will examine in detail various stages of the viral life cycle. Beginning with the viral entry into a host cell, the book takes the reader through replication of the genome, synthesis and assembly of viral structural components, genome packaging and maturation into an infectious virion. Each chapter will describe the components of the respective machine in molecular or atomic detail, genetic and biochemical analyses, and mechanism. Topics are carefully selected so that the reader is exposed to systems where there is a substantial infusion of new knowledge in recent years, which greatly elevated the fundamental mechanistic understanding of the respective molecular machine. The authors will be encouraged to simplify the detailed knowledge to basic concepts, include provocative new ideas, as well as design colorful graphics, thus making the cutting-edge information accessible to broad audience.

Available in PDF, EPUB and Kindle. Book excerpt: Diffusion processes are a promising instrument for realistically modelling the time-continuous evolution of phenomena not only in the natural sciences but also in finance and economics. Their mathematical theory, however, is challenging, and hence diffusion modelling is often carried out incorrectly, and the according statistical inference is considered almost exclusively by theoreticians. This book explains both topics in an illustrative way which also addresses practitioners. It provides a complete overview of the current state of research and presents important, novel insights. The theory is demonstrated using real data applications.
Download or read book Empires of Panic written by Robert Peckham and published by Hong Kong University Press. This book was released on 2015-01-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Empires of Panic is the first book to explore how panics have been historically produced, defined, and managed across different colonial, imperial, and post-imperial settings—from early nineteenth-century East Asia to twenty-first-century America. Contributors consider panic in relation to colonial anxieties, rumors, indigenous resistance, and crises, particularly in relation to epidemic disease. How did Western government agencies, policymakers, planners, and other authorities understand, deal with, and neutralize panics? What role did evolving technologies of communication play in the amplification of local panics into global events? Engaging with these questions, the book challenges conventional histories to show how intensifying processes of intelligence gathering did not consolidate empire, but rather served to produce critical uncertainties—the uneven terrain of imperial panic. Robert Peckham is associate professor in the Department of History and co-director of the Centre for the Humanities and Medicine at the University of Hong Kong. "Charting the relays of rumor and knowledge that stoke colonial fears of disease, disorder, and disaster, Empires of Panic offers timely and cautionary insight into how viscerally epidemics inflame imperial anxieties, and how words and their communication over new technologies accelerate panic, rally government intervention, and unsettle and entrench the exercise of global power. Relevant a century ago and even more so today." — Nayan Shah, University of Southern California; author ofContagious Divides: Epidemics and Race in San Francisco's Chinatown "Empires generated anxiety as much as ambition. This fine study focuses on anxieties generated by disease. It is the first book of its kind to track shifting forms of panic through different geopolitical regimes and imperial formations over the course of two centuries. Working across medical and imperial histories, it is a major contribution to both." — Andrew S. Thompson, University of Exeter; author of Empire and Globalisation: Networks of People, Goods and Capital in the British World, c. 1850–1914(with Gary B. Magee)
Download or read book The Geography of Transport Systems written by Jean-Paul Rodrigue and published by Routledge. This book was released on 2013-07-18 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobility is fundamental to economic and social activities such as commuting, manufacturing, or supplying energy. Each movement has an origin, a potential set of intermediate locations, a destination, and a nature which is linked with geographical attributes. Transport systems composed of infrastructures, modes and terminals are so embedded in the socio-economic life of individuals, institutions and corporations that they are often invisible to the consumer. This is paradoxical as the perceived invisibility of transportation is derived from its efficiency. Understanding how mobility is linked with geography is main the purpose of this book. The third edition of The Geography of Transport Systems has been revised and updated to provide an overview of the spatial aspects of transportation. This text provides greater discussion of security, energy, green logistics, as well as new and updated case studies, a revised content structure, and new figures. Each chapter covers a specific conceptual dimension including networks, modes, terminals, freight transportation, urban transportation and environmental impacts. A final chapter contains core methodologies linked with transport geography such as accessibility, spatial interactions, graph theory and Geographic Information Systems for transportation (GIS-T). This book provides a comprehensive and accessible introduction to the field, with a broad overview of its concepts, methods, and areas of application. The accompanying website for this text contains a useful additional material, including digital maps, PowerPoint slides, databases, and links to further reading and websites. The website can be accessed at: http://people.hofstra.edu/geotrans This text is an essential resource for undergraduates studying transport geography, as well as those interest in economic and urban geography, transport planning and engineering.
