Population, Place, and Spatial Interaction: Essays in Honor of David Plane (New Frontiers in Regional Science: Asian Perspectives #40)
by Rachel S. FranklinThis volume is devoted to the geographical—or spatial—aspects of population research in regional science, spanning spatial demographic methods for population composition and migration to studies of internal and international migration to investigations of the role of population in related fields such as climate change and economic growth. If spatial aspects of economic growth and development are the flagship of the regional science discipline, population research is the anchor. People migrate, consume, produce, and demand services. People are the source and beneficiaries of national, regional, and local growth and development. Since the origins of regional science, demographic research has been at the core of the discipline. Contributions in this volume are both retrospective and prospective, offering in their ensemble an authoritative overview of demographic research within the field of regional science.
Population Politics: The Choices That Shape Our Future
by Virginia Abernethy Garrett HardinInternational efforts to regulate fertility rates so that populations do not grow beyond the earth's capacity have included technical assistance and capital; improved health care conditions to lower the risk of infant mortality; increased opportunities to develop literacy; the democratization of governments; and several decades of liberal immigration and refugee policies favoring third world nations. The persistence of high fertility despite international efforts confounds demographers. 'Population Politics' brilliantly dissects the paradigm responsible for the counterproductive efforts of nations and international agencies. Abernethy, a renowned anthropologist, shows why policies hamper the shift to lower fertility. Ireland, Indonesia, Cuba, China, Turkey and Egypt are but a few of the countries Abernethy examines, showing how economic, sociocultural, and agricultural factors that have caused population growth can be harnessed to stabilize population size. 'Population Politics' is a provocative examination of the influence of aid and liberal immigration policies on world population growth, and often counterproductive to the role of the United States as an industrial power. This volume's uniquely interdisciplinary perspective will enlighten the lay reader, as well as demographers and epidemiologists, conservationists, reproduction and family specialists, agricultural economists, and public health personnel. Virginia D. Abernethy is professor emeritus of psychiatry (anthropology) at Vanderbilt Medical School and was for 11 years the editor of the scholarly journal 'Population and Environment. Garrett Hardin is emeritus professor of human ecology in the Department of Biological Sciences and the University of California, Santa Barbara.
Population Pressure and Cultural Adjustment
by Virginia Deane AbernethyIntegrating research from anthropology, biology, and history, this provocative, brilliant book proposes a theory of demographic equilibrium. The author's hypothesis is that human beings, like many other species, are able to adjust their population numbers to the carrying capacity of the environment. Abernethy points out that in response to perception of scarcity or abundance of resources, culturally mediated values, beliefs and behavioral patterns are modified in ways that can either raise or lower rates of population growth. Abernethy in this way moves beyond the ideological debates that have sundered the field of policy and population. In real world time and space, cultural adjustments that balance population and resources are made over a long stretch in relatively stable or known environments. These adjustments also operate in processes that involve technological advances that appear to increase carrying capacity, and these usually act to support and underwrite population growth in any given area. In her new introduction to this first paperback edition, Abernethy shows how many of the cultural changes the book predicted in 1979 have come to pass. She details a complex of behaviors that favor single life-styles or small family size that have contributed to low fertility rates among native-born Americans while fertility rates among immigrants continue to climb. Population Pressure and Cultural Adjustment is not simply a theoretical slogan, but discusses a rich set of different cultural situations where this homeostatic process has been disrupted or aborted. Often, disruption occurs after the infusion of foreign value systems as well as new forms of technological innovation, or when highly permeable social boundaries result in the importation of resources for which the limits and consequences are not fully appreciated by the host population. This work will inevitably be controversial because of its implications for the limits as well as the potential of public policy in both advanced and underdeveloped societies.
Population Reconstruction
by Gerrit Bloothooft Peter Christen Kees Mandemakers Marijn SchraagenThis book addresses the problems that are encountered, and solutions that have been proposed, when we aim to identify people and to reconstruct populations under conditions where information is scarce, ambiguous, fuzzy and sometimes erroneous. The process from handwritten registers to a reconstructed digitized population consists of three major phases, reflected in the three main sections of this book. The first phase involves transcribing and digitizing the data while structuring the information in a meaningful and efficient way. In the second phase, records that refer to the same person or group of persons are identified by a process of linkage. In the third and final phase, the information on an individual is combined into a reconstruction of their life course. The studies and examples in this book originate from a range of countries, each with its own cultural and administrative characteristics, and from medieval charters through historical censuses and vital registration, to the modern issue of privacy preservation. Despite the diverse places and times addressed, they all share the study of fundamental issues when it comes to model reasoning for population reconstruction and the possibilities and limitations of information technology to support this process. It is thus not a single discipline that is involved in such an endeavor. Historians, social scientists, and linguists represent the humanities through their knowledge of the complexity of the past, the limitations of sources, and the possible interpretations of information. The availability of big data from digitized archives and the need for complex analyses to identify individuals calls for the involvement of computer scientists. With contributions from all these fields, often in direct cooperation, this book is at the heart of the digital humanities, and will hopefully offer a source of inspiration for future investigations.
Population, Sanitation and Health: A Geographical Study Towards Sustainability
by Asraful Alam Rukhsana Nazrul Islam Bappa Sarkar Ranjan RoyThis book provides analyses of sanitation, health, population dynamics and demographic variables from different perspectives, including data science, statistics, modeling, economics and natural sciences, to inform sustainable decision making and policies related public health and hygiene and in mainly rural and impoverished areas. The structure is arranged into three broad sections: Part I, Population Dynamics, Environment and Society; Part II, Health, Livelihood and Policy Response; and Part III, Water, Sanitation, and Hygiene (WASH). The book makes recommendations for policymakers on designing and delivering social protection policies to deal with different aspects of water, health, sanitation, population, and hygiene, taking the needs of women and rural communities into special consideration. It also aims to educate students and early career researchers, to help them develop novel approaches for sustainability with environmentally sound practices.
Population Since the Industrial Revolution: The Case of England and Wales (Routledge Library Editions: Demography #13)
by Neil TranterOriginally published in 1973, this book is an introduction to the study of population history since the Industrial Revolution and focuses on the experience of England and Wales. It provides both a comprehensive survey of the vast array of specialist literature and a thorough explanation of the sources and methodology of historical demographic analysis. Throughout special emphasis is given to the need to recognise that the historical pattern of population growth in England and Wales has been broadly similar to that observed elsewhere in Western Europe. The sources and techniques of historical demography are discussed and the general outline of population growth between 1688 and 1939 examined. The factors responsible for the dramatic increase in population growth during the late 18th and 19th Centuries are analysed as are the causes of the abrupt down-turn in rate of population following World War 1. The part played by population change in the development of the British economy and the impact of population change on society are also covered. By integrating the social and economic impact of population change with sources and methods, this text fills a gap and will be of essential reading to students in economics, sociology and social history.
Population Structures and Models: Developments in Spatial Demography (Routledge Library Editions: Demography #14)
by Robert Woods Philip ReesOriginally published in 1986, this volume brings together geographical modelling of population change and demographic analysis of population structures and pattern. These 2 strands are interwoven in 3 key review chapters that summarize the study of spatial and temporal patterns of population, the modelling of spatial populations and the estimation of population processes. Findings reported include: An account of demographic transition; an exposé of the myth of ‘no fertility rises’ in the developing world in the 20th Century; a theory of population accounting; predicting migration flows for a system of regions; microsimulation methods to model population change; and demographic and economic processes integrated in an urban region model.
Population Studies and Development from Theory to Fieldwork
by Véronique PetitThis book addresses major population and development issues: fertility and reproductive health, migrations, gender, education, poverty and inequalities. To that aim it revisits and considerably enlarges Kingsley Davis’ 1963 theory of change and response, using interdisciplinary methodologies. On the basis of four decades of field research (1985-2015), it questions the rationality of the actors, how culture shapes socio-demographic behaviours, in a context of modernity and globalisation. More specifically, it casts new light on the interactions of individuals, families, networks and local communities with the State and its population policy.
Population Studies in the Western Balkans (European Studies of Population #26)
by Konstantinos N. Zafeiris Byron Kotzamanis Christos SkiadasThis book is a collection of scientific studies regarding the biological, economic, historical, health, social, and other aspects of the populations of the western Balkans, a geographic area with distinct as well as diverse socioeconomic backgrounds, political systems, ethnic characteristics, development, and history. Through providing data analyses, statistical methodologies, and important applications, the book addresses and explores topics such as temporary migration and human resource availability, depopulation, and the immigration future, returning migrants, poverty, population dynamics and birth rate trends, reproduction and family creation, aging, mortality and health developments, and much more. As such, this book is of great importance in understanding the mechanisms of population change and dynamics in an European area and provides a valuable guide for researchers, policy makers, and practitioners from various disciplines.
Population Trends in New Jersey
by James W. Hughes David ListokinTo fully understand New Jersey in the 2020s and beyond, it is crucial to understand its ever-changing population. This book examines the twenty-first century demographic trends that are reshaping the state now and will continue to do so in the future. But trend analysis requires a deep historical context. Present-day New Jersey is the result of a long demographic and economic journey that has taken place over centuries, constantly influenced by national and global forces. This book provides a detailed examination of this journey. The result is present-day New Jersey. The authors also highlight key trends that will continue to transform the state: domestic migration out of the state and immigration into it; increasing diversity; slower overall population growth; contracting fertility; the household revolution and changing living arrangements; generational disruptions; and suburbanization versus re-urbanization. All of these factors help place in context the result of the 2020 decennial U.S. Census. While the book focuses on New Jersey, the Garden State is a template of demographic, economic, social, and other forces characterizing the United States in the twenty-first century.
Pore Structure in Food: Simulation, Measurement and Applications
by Zeynep Hicsasmaz Alper GuevenThe pore structure of foods directly affects the success of such food processes as drying, puffing, freeze-drying, and rehydration. Consequently, the pore structure of foods determines what types of food processes will work best with a particular food. This Brief will first discuss in depth the need to correctly measure the pore structure of foods and then will identify and describe in detail the current methods available to measure food porosity. Finally, it will review the applications of these various methods.
Portfolio Management Under Stress
by Riccardo RebonatoPortfolio Management under Stress offers a novel way to apply the well-established Bayesian-net methodology to the important problem of asset allocation under conditions of market distress or, more generally, when an investor believes that a particular scenario (such as the break-up of the Euro) may occur. Employing a coherent and thorough approach, it provides practical guidance on how best to choose an optimal and stable asset allocation in the presence of user specified scenarios or 'stress conditions'. The authors place causal explanations, rather than association-based measures such as correlations, at the core of their argument, and insights from the theory of choice under ambiguity aversion are invoked to obtain stable allocations results. Step-by-step design guidelines are included to allow readers to grasp the full implementation of the approach, and case studies provide clarification. This insightful book is a key resource for practitioners and research academics in the post-financial crisis world.
Portfolio Optimization (Chapman and Hall/CRC Financial Mathematics Series)
by Michael J. BestEschewing a more theoretical approach, Portfolio Optimization shows how the mathematical tools of linear algebra and optimization can quickly and clearly formulate important ideas on the subject. This practical book extends the concepts of the Markowitz "budget constraint only" model to a linearly constrained model.Only requiring elementary linear algebra, the text begins with the necessary and sufficient conditions for optimal quadratic minimization that is subject to linear equality constraints. It then develops the key properties of the efficient frontier, extends the results to problems with a risk-free asset, and presents Sharpe ratios and implied risk-free rates. After focusing on quadratic programming, the author discusses a constrained portfolio optimization problem and uses an algorithm to determine the entire (constrained) efficient frontier, its corner portfolios, the piecewise linear expected returns, and the piecewise quadratic variances. The final chapter illustrates infinitely many implied risk returns for certain market portfolios.Drawing on the author’s experiences in the academic world and as a consultant to many financial institutions, this text provides a hands-on foundation in portfolio optimization. Although the author clearly describes how to implement each technique by hand, he includes several MATLAB® programs designed to implement the methods and offers these programs on the accompanying downloadable resources.
Portfolio Optimization and Performance Analysis (Chapman and Hall/CRC Financial Mathematics Series)
by Jean-Luc PrigentIn answer to the intense development of new financial products and the increasing complexity of portfolio management theory, Portfolio Optimization and Performance Analysis offers a solid grounding in modern portfolio theory. The book presents both standard and novel results on the axiomatics of the individual choice in an uncertain framework, cont
Portfolio Rebalancing (Chapman and Hall/CRC Financial Mathematics)
by Edward E. QianThe goal of Portfolio Rebalancing is to provide mathematical and empirical analysis of the effects of portfolio rebalancing on portfolio returns and risks. The mathematical analysis answers the question of when and why fixed-weight portfolios might outperform buy-and-hold portfolios based on volatilities and returns. The empirical analysis, aided by mathematical insights, will examine the effects of portfolio rebalancing in capital markets for asset allocation portfolios and portfolios of stocks, bonds, and commodities.
Portfolio Selection
by Harry M. MarkowitzThis is a classic book, representing the first major breakthrough in the field of modern financial theory. In effect, it created the mathematics of portfolio selection in a model which has turned out to be the indispensable building block from which the theory of the demand for risky securities is constructed. It also became an essential reference for individuals and financial institutions actually selecting optimal portfolios. Long out of print and unavailable to numerous recent entrants to both financial theory and financial practice, this new edition leaves the existing text as it stands but adds substantial new material including a new bibliography and a fascinating biographical piece on the birth of the field of finance.
The Portfolio Theorists
by Colin ReadRead examines probability, risk, and uncertainty through the contributions of John von Neumann, Leonard Jimmie Savage, Kenneth Arrow and Harry Markowitz. These Portfolio Theorists provided us with a dramatic leap forward in our understanding of and insights into financial rewards under risk and uncertainty.
A Portrait of America
by John IcelandPortrait of America describes our nation's changing population and examines through a demographic lens some of our most pressing contemporary challenges, ranging from poverty and economic inequality to racial tensions and health disparities. Celebrated authorJohn Iceland covers various topics, including America's historical demographic growth; the American family today; gender inequality; economic well-being; immigration and diversity; racial and ethnic inequality; internal migration and residential segregation; and health and mortality. The discussion of these topics is informed by several sources, including an examination of household survey data, and by syntheses of existing published material, both quantitative and qualitative. Iceland discusses the current issues and controversies around these themes, highlighting their role in everyday debates taking place in Congress, the media, and in American living rooms. Each chapter includes historical background, as well as a discussion of how patterns and trends in the United States compare to those in peer countries.
Poset Codes: Partial Orders, Metrics and Coding Theory (SpringerBriefs in Mathematics)
by Marcelo Firer Marcelo Muniz S. Alves Jerry Anderson Pinheiro Luciano PanekThis book offers an organized and systematic approach to poset metrics and codes. Poset metrics, or metrics on a vector field determined by a partial order over a finite set, were first introduced in the mid-1990s by the mathematicians Richard A. Brualdi, Janine S. Graves and K. Mark Lawrence, and to date the relevant knowledge on this subject was spread over more than two hundred research papers. Poset metrics generalizes both the standard Hamming metric – the most important metric used in the context of coding theory – and the Niederreiter-Rosenbloom-Tsfasman metric, which is an ultrametric. Conceived to be as self-contained as possible, the book starts from basic concepts of coding theory and advances towards coding theory for poset metrics and generalizations. Each chapter includes a survey of the topic presented and a list of exercises, drawn in part from recently proven results. This work will appeal to researchers and graduate students alike, particularly those in the fields of Mathematics, Electrical Engineering and Computer Sciences, with an interest in discrete geometry and coding theory.
Posing and Solving Mathematical Problems
by Patricio Felmer Erkki Pehkonen Jeremy KilpatrickThis book collects recent research on posing and solving mathematical problems. Rather than treating these two crucial aspects of school mathematics as separate areas of study, the authors approach them as a unit where both areas are measured on equal grounds in relation to each other. The contributors are from a vast variety of countries and with a wide range of experience; it includes the work from many of the leading researchers in the area and an important number of young researchers. The book is divided in three parts, one directed to new research perspectives and the other two directed to teachers and students, respectively.
Positioning and Navigation Using Machine Learning Methods (Navigation: Science and Technology #14)
by Kegen YuThis is the first book completely dedicated to positioning and navigation using machine learning methods. It deals with ground, aerial, and space positioning and navigation for pedestrians, vehicles, UAVs, and LEO satellites. Most of the major machine learning methods are utilized, including supervised learning, unsupervised learning, deep learning, and reinforcement learning. The book presents both fundamentals and in-depth studies as well as practical examples in positioning and navigation. Extensive data processing and experimental results are provided in the major chapters through conducting experimental campaigns or using in-situ measurements.
Positive Aging and Precarity: Theory, Policy, and Social Reality within a Comparative German Context (International Perspectives on Aging #21)
by Irina Catrinel CrăciunThis book explores positive aging through the lens of precarity, aiming to ground positive aging theories in current social contexts. In recent years, research on aging has been branded by growing disagreements between supporters of the successful aging model and critical gerontologists who highlight the widening inequalities, disadvantages and precarity that characterize old age. This book comes to fill a gap in knowledge by offering an alternative view on positive aging, informed by precarity and its impact on projections concerning aging.The first part of the book places aging in broader theoretical and empirical context, exploring the complex links between views on aging, successful aging theories, policy and social reality. The second part uses results from a qualitative research conducted in Germany to illustrate the dissonance between successful aging ideals and both negative and positive views on aging as well as aging preparation strategies inspired by precarity. Findings from this section provide a solid starting point for comparisons with countries that are both similar and different from Germany in terms of welfare regimes and aging policies. The final part of the book discusses the psychological implications of these findings within and beyond the German case study and outlines potential solutions for practice. This book provides health psychologists, gerontologists, sociologists, social workers, health professionals as well as students and aging individuals themselves with better understanding of the meaning of aging in precarious times and builds confidence about aging well despite precarity.
Positive Definite Matrices (Princeton Series in Applied Mathematics #24)
by Rajendra BhatiaThis book represents the first synthesis of the considerable body of new research into positive definite matrices. These matrices play the same role in noncommutative analysis as positive real numbers do in classical analysis. They have theoretical and computational uses across a broad spectrum of disciplines, including calculus, electrical engineering, statistics, physics, numerical analysis, quantum information theory, and geometry. Through detailed explanations and an authoritative and inspiring writing style, Rajendra Bhatia carefully develops general techniques that have wide applications in the study of such matrices. Bhatia introduces several key topics in functional analysis, operator theory, harmonic analysis, and differential geometry--all built around the central theme of positive definite matrices. He discusses positive and completely positive linear maps, and presents major theorems with simple and direct proofs. He examines matrix means and their applications, and shows how to use positive definite functions to derive operator inequalities that he and others proved in recent years. He guides the reader through the differential geometry of the manifold of positive definite matrices, and explains recent work on the geometric mean of several matrices. Positive Definite Matrices is an informative and useful reference book for mathematicians and other researchers and practitioners. The numerous exercises and notes at the end of each chapter also make it the ideal textbook for graduate-level courses.
Positive Linear Maps of Operator Algebras
by Erling StørmerThis volume, setting out the theory of positive maps as it stands today, reflects the rapid growth in this area of mathematics since it was recognized in the 1990s that these applications of C*-algebras are crucial to the study of entanglement in quantum theory. The author, a leading authority on the subject, sets out numerous results previously unpublished in book form. In addition to outlining the properties and structures of positive linear maps of operator algebras into the bounded operators on a Hilbert space, he guides readers through proofs of the Stinespring theorem and its applications to inequalities for positive maps. The text examines the maps' positivity properties, as well as their associated linear functionals together with their density operators. It features special sections on extremal positive maps and Choi matrices. In sum, this is a vital publication that covers a full spectrum of matters relating to positive linear maps, of which a large proportion is relevant and applicable to today's quantum information theory. The latter sections of the book present the material in finite dimensions, while the text as a whole appeals to a wider and more general readership by keeping the mathematics as elementary as possible throughout.
Positive Trigonometric Polynomials and Signal Processing Applications
by Bogdan DumitrescuPositive Trigonometric Polynomials and Signal Processing Applications has two parts: theory and applications. The theory of sum-of-squares trigonometric polynomials is presented unitarily based on the concept of Gram matrix (extended to Gram pair or Gram set). The presentation starts by giving the main results for univariate polynomials, which are later extended and generalized for multivariate polynomials. The applications part is organized as a collection of related problems that use systematically the theoretical results. All the problems are brought to a semidefinite programming form, ready to be solved with algorithms freely available, like those from the library SeDuMi.
