Download or read book The Population Biology of Tuberculosis written by Christopher Dye and published by Princeton University Press. This book was released on 2015-07-07 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite decades of developments in immunization and drug therapy, tuberculosis remains among the leading causes of human mortality, and no country has successfully eradicated the disease. Reenvisioning tuberculosis from the perspective of population biology, this book examines why the disease is so persistent and what must be done to fight it. Treating tuberculosis and its human hosts as dynamic, interacting populations, Christopher Dye seeks new answers to key questions by drawing on demography, ecology, epidemiology, evolution, and population genetics. Dye uses simple mathematical models to investigate how cases and deaths could be reduced, and how interventions could lead to TB elimination. Dye's analysis reveals a striking gap between the actual and potential impact of current interventions, especially drug treatment, and he suggests placing more emphasis on early case detection and the treatment of active or incipient tuberculosis. He argues that the response to disappointingly slow rates of disease decline is not to abandon long-established principles of chemotherapy, but to implement them with greater vigor. Summarizing epidemiological insights from population biology, Dye stresses the need to take a more inclusive view of the factors that affect disease, including characteristics of the pathogen, individuals and populations, health care systems, and physical and social environments. In broadening the horizons of TB research, The Population Biology of Tuberculosis demonstrates what must be done to prevent, control, and defeat this global threat in the twenty-first century.

Download or read book Sensitivity Analysis Matrix Methods in Demography and Ecology written by Hal Caswell and published by Springer. This book was released on 2019-04-02 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book shows how to use sensitivity analysis in demography. It presents new methods for individuals, cohorts, and populations, with applications to humans, other animals, and plants. The analyses are based on matrix formulations of age-classified, stage-classified, and multistate population models. Methods are presented for linear and nonlinear, deterministic and stochastic, and time-invariant and time-varying cases. Readers will discover results on the sensitivity of statistics of longevity, life disparity, occupancy times, the net reproductive rate, and statistics of Markov chain models in demography. They will also see applications of sensitivity analysis to population growth rates, stable population structures, reproductive value, equilibria under immigration and nonlinearity, and population cycles. Individual stochasticity is a theme throughout, with a focus that goes beyond expected values to include variances in demographic outcomes. The calculations are easily and accurately implemented in matrix-oriented programming languages such as Matlab or R. Sensitivity analysis will help readers create models to predict the effect of future changes, to evaluate policy effects, and to identify possible evolutionary responses to the environment. Complete with many examples of the application, the book will be of interest to researchers and graduate students in human demography and population biology. The material will also appeal to those in mathematical biology and applied mathematics.
Download or read book Complex Population Dynamics written by Peter Turchin and published by Princeton University Press. This book was released on 2013-02-15 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do organisms become extremely abundant one year and then seem to disappear a few years later? Why do population outbreaks in particular species happen more or less regularly in certain locations, but only irregularly (or never at all) in other locations? Complex population dynamics have fascinated biologists for decades. By bringing together mathematical models, statistical analyses, and field experiments, this book offers a comprehensive new synthesis of the theory of population oscillations. Peter Turchin first reviews the conceptual tools that ecologists use to investigate population oscillations, introducing population modeling and the statistical analysis of time series data. He then provides an in-depth discussion of several case studies--including the larch budmoth, southern pine beetle, red grouse, voles and lemmings, snowshoe hare, and ungulates--to develop a new analysis of the mechanisms that drive population oscillations in nature. Through such work, the author argues, ecologists can develop general laws of population dynamics that will help turn ecology into a truly quantitative and predictive science. Complex Population Dynamics integrates theoretical and empirical studies into a major new synthesis of current knowledge about population dynamics. It is also a pioneering work that sets the course for ecology's future as a predictive science.
Download or read book Sex Allocation written by Stuart West and published by Princeton University Press. This book was released on 2009-09-28 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed an explosion of theoretical and empirical studies of sex allocation, transforming how we understand the allocation of resources to male and female reproduction in vertebrates, invertebrates, protozoa, and plants. In this landmark book, Stuart West synthesizes the vast literature on sex allocation, providing the conceptual framework the field has been lacking and demonstrating how sex-allocation studies can shed light on broader questions in evolutionary and behavioral biology. West clarifies fundamental misconceptions in the application of theory to empirical data. He examines the field's successes and failures, and describes the research areas where much important work is yet to be done. West reveals how a shared underlying theoretical framework unites findings of sex-ratio variation across a huge range of life forms, from malarial parasites and hermaphroditic worms to sex-changing fish and mammals. He shows how research on sex allocation has been central to many critical questions and controversies in evolutionary and behavioral biology, and he argues that sex-allocation research serves as a key testing ground for different theoretical approaches and can help resolve debates about social evolution, parent-offspring conflict, genomic conflict, and levels of selection. Certain to become the defining book on the subject for the next generation of researchers, Sex Allocation explains why the study of sex allocation provides an ideal model system for advancing our understanding of the constraints on adaptation among all living things in the natural world.

Download or read book Migration and Health in a Small Society written by Albert F. Wessen and published by . This book was released on 1992 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 1965 and 1975, a large proportion of the population of Tokelau, a group of three tiny isolated atolls in the tropical South Pacific, migrated to New Zealand, where they became part of a cosmopolitan urban society. By 1985, two-thirds of all Tokelauans lived in New Zealand. This book traces the experience of the Tokelauans, both migrant and non-migrant, during the period 1965-85. The analysis is interdisciplinary, drawing upon historical, ethnographic, sociological, and epidemiological materials. Topics discussed include the ecology and history of Tokelau, the nature of Tokelauan culture and society, the problems of adaptation faced by migrants to New Zealand and their efforts to develop a viable Tokelauan community there, the impact of modernizing influences upon atoll society, changes in the health status of both migrant and non-migrant Tokelauans, and the relationship of social change to the health of the population. Special attention is paid to the hypothesis that the migrants' adaptation to modern urban society would lead to increased incidence of such chronic conditions as hypertension, coronary heart disease, asthma, and diabetes. The work serves as a valuable and in many ways unique source of information for public health professionals, medical anthropologists, sociologists and specialists in development policy.

Download or read book Schistosomes Liver Flukes and Helicobacter Pylori written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 1994 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates the carcinogenic risk to humans posed by infection with three schistosoma trematodes, three liver flukes and the bacterium Helicobacter pylori. These biological agents were selected for evaluation on the basis of evidence suggesting a causal association between infection and the development of human cancers. The first monograph assesses data on Schistosoma haematobium S. mansoniand S. japonicum, the three species which account for the vast majority of schistosomal disease in humans. The most extensive sections evaluate the results of studies of cancer in humans and experimental animals, concentrating on the strength of evidence linking infection with S. haematobium to squamous-cell carcinoma of the urinary bladder, and infection with S. mansoni or S. japonicum to an increased risk for cancers of the gastrointestinal tract. The monograph concludes that infection with S. haematobium is carcinogenic to humans and that infection with S. japonicum is possibly carcinogenic to humans; infection with S. mansoni could not be classified. The second monograph on liver flukes evaluates data on Opisthorchis viverriniO. felineus and Clonorchis sinensis. These foodborne trematodes establish a chronic infection of the bile ducts and more rarely the pancreatic duct and gall-bladder of humans and other mammals. Most carcinogenicity data centre on the possibility that these trematodes are involved in the development of cholangiocarcinoma or liver cancer. The monograph concludes that infection with O. viverrini is carcinogenic to humans and that infection with C. sinensis is probably carcinogenic to humans; infection with O. felineus could not be classified. The final monograph evaluates data on Helicobacter pylori. More than half of the world's population may be infected with this bacterium, which is responsible for most cases of chronic gastritis and duodenal ulcer. Citing several studies linking infection to gastric cancer in humans, the monograph concludes that infection with H. pylori is carcinogenic to humans.
Download or read book Niche Construction written by F. John Odling-Smee and published by Princeton University Press. This book was released on 2013-02-15 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seemingly innocent observation that the activities of organisms bring about changes in environments is so obvious that it seems an unlikely focus for a new line of thinking about evolution. Yet niche construction--as this process of organism-driven environmental modification is known--has hidden complexities. By transforming biotic and abiotic sources of natural selection in external environments, niche construction generates feedback in evolution on a scale hitherto underestimated--and in a manner that transforms the evolutionary dynamic. It also plays a critical role in ecology, supporting ecosystem engineering and influencing the flow of energy and nutrients through ecosystems. Despite this, niche construction has been given short shrift in theoretical biology, in part because it cannot be fully understood within the framework of standard evolutionary theory. Wedding evolution and ecology, this book extends evolutionary theory by formally including niche construction and ecological inheritance as additional evolutionary processes. The authors support their historic move with empirical data, theoretical population genetics, and conceptual models. They also describe new research methods capable of testing the theory. They demonstrate how their theory can resolve long-standing problems in ecology, particularly by advancing the sorely needed synthesis of ecology and evolution, and how it offers an evolutionary basis for the human sciences. Already hailed as a pioneering work by some of the world's most influential biologists, this is a rare, potentially field-changing contribution to the biological sciences.

This book was released on 2003-02-01 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anthrax incidents following the 9/11 terrorist attacks put the spotlight on the nation's public health agencies, placing it under an unprecedented scrutiny that added new dimensions to the complex issues considered in this report. The Future of the Public's Health in the 21st Century reaffirms the vision of Healthy People 2010, and outlines a systems approach to assuring the nation's health in practice, research, and policy. This approach focuses on joining the unique resources and perspectives of diverse sectors and entities and challenges these groups to work in a concerted, strategic way to promote and protect the public's health. Focusing on diverse partnerships as the framework for public health, the book discusses: The need for a shift from an individual to a population-based approach in practice, research, policy, and community engagement. The status of the governmental public health infrastructure and what needs to be improved, including its interface with the health care delivery system. The roles nongovernment actors, such as academia, business, local communities and the media can play in creating a healthy nation. Providing an accessible analysis, this book will be important to public health policy-makers and practitioners, business and community leaders, health advocates, educators and journalists.
Download or read book Human Populations written by Anthony J. Boyce and published by Oxford University Press, USA. This book was released on 1995 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human populations--groups of people living together and sharing a number of biological and social characteristics--differ from one another in many important respects. Human Evolution: Diversity and Adaptation provides a succinct and insightful exploration of the many genetic and environmental conditions that have led to such differences. In describing the specific kinds of diversity--genetic, morphological, social, and disease associations--the book presents case studies that clearly show how such differences interact to produce the variety of human populations that exist around the world. It also stresses the point that human history is to some extent the history of migration, resulting in populations that are not discrete entities but rather a continuous gradation of various physical and cultural attributes. Splendidly written by leading experts, Human Evolution is an excellent compendium that explores the multifaceted field of human evolution.
