Demography for Planning and Policy: Australian Case Studies

by Tom Wilson Elin Charles-Edwards Martin Bell

​This edited collection shows how demographic analysis plays a pivotal role in planning, policy and funding decisions in Australia. Drawing on the latest demographic data and methods, these case studies in applied demography demonstrate that population dynamics underpin the full spectrum of contemporary social, economic and political issues. The contributors harness a range of demographic statistics and develop innovative techniques demonstrating how population dynamics influence issues such as electoral representation, the distribution of government funding, metropolitan and local planning, the provision of aged housing, rural depopulation, coastal growth, ethnic diversity and the well-being of Australia's Indigenous community. Moving beyond simple statistics, the case studies show that demographic methods and models offer crucial insights into contemporary problems and provide essential perspectives to aid efficiency, equity in public policy and private sector planning. Together the volume represents essential reading for students across the social sciences as for policy makers in government and private industry.

The Changing Migrant Composition of Australia’s Population: Past, Present and Future (SpringerBriefs in Population Studies)

by Tom Wilson Jeromey Temple Peter McDonald Ariane Utomo Bianca Brijnath

This book looks at how Australia's migrant population composition is likely to change over coming decades. The book divides Australia's population into 48 countries of birth groupings and projects the birthplace populations out to 2066 according to the range of scenarios. These projections indicate a massive shift in Australia’s migrant composition from a European to an Asian-dominated population over the coming decades—a change which can be interpreted as a third demographic transition. By providing detailed consideration of the implications of the changing population composition, this book is a great resource for academics, government and private sector services.

Zum Potenzial von Anschauung in der mathematischen Hochschullehre: Eine Untersuchung am Beispiel interaktiver dynamischer Visualisierungen in der Analysis (Essener Beiträge zur Mathematikdidaktik)

by Wieland Wilzek

Der Übergang von der Schule zur Hochschule im Fach Mathematik stellt viele Studierende vor verschiedene Schwierigkeiten, wobei der veränderte Umgang mit Anschauung eine besondere Herausforderung sein kann. Es ist denkbar, dass eine stärker anschaulich ausgerichtete Hochschulmathematik die Übergangsproblematik abmildert. Das Hauptanliegen dieser Arbeit besteht daher darin, zu klären, welche Rolle Anschauung in der mathematischen Hochschullehre spielen sollte. Dabei liegt der Fokus auf der Lehrveranstaltung Analysis. Zunächst wir eine Definition von Anschauung entwickelt und verschiedene Einsatzarten von Anschauung werden unterschieden, um diese bezüglich ihrer Angemessenheit zu bewerten. Daran anschließend wird ein Vorschlag vorgestellt, wie durch interaktive dynamische Visualisierungen Anschauung in die mathematische Hochschullehre eingebunden werden kann. Abschließend werden in einer empirischen Untersuchung anschauliche Elemente in Beweisprozessen von Studierenden rekonstruiert, deren Lernprozesse durch interaktive dynamische Visualisierungen unterstützt wurden. Die anschaulichen Elemente werden in einer Typologie zusammengefasst und die so gewonnenen Typen bezüglich des Potenzials, welches diese für das Führen von Beweisen bieten, bewertet.

Handbook of Item Response Theory, Volume Two: Statistical Tools (Chapman & Hall/CRC Statistics in the Social and Behavioral Sciences)

by Wim J. van der Linden

Drawing on the work of internationally acclaimed experts in the field, Handbook of Item Response Theory, Volume Two: Statistical Tools presents classical and modern statistical tools used in item response theory (IRT). While IRT heavily depends on the use of statistical tools for handling its models and applications, systematic introductions and reviews that emphasize their relevance to IRT are hardly found in the statistical literature. This second volume in a three-volume set fills this void. Volume Two covers common probability distributions, the issue of models with both intentional and nuisance parameters, the use of information criteria, methods for dealing with missing data, and model identification issues. It also addresses recent developments in parameter estimation and model fit and comparison, such as Bayesian approaches, specifically Markov chain Monte Carlo (MCMC) methods.

Geographic Data Science with R: Visualizing and Analyzing Environmental Change (Chapman & Hall/CRC Data Science Series)

by Michael C. Wimberly

The burgeoning field of data science has provided a wealth of techniques for analysing large and complex geospatial datasets, including descriptive, explanatory, and predictive analytics. However, applying these methods is just one part of the overall process of geographic data science. Other critical steps include screening for suspect data values, handling missing data, harmonizing data from multiple sources, summarizing the data, and visualizing data and analysis results. Although there are many books available on statistical and machine learning methods, few encompass the broader topic of scientific workflows for geospatial data processing and analysis. The purpose of Geographic Data Science with R is to fill this gap by providing a series of tutorials aimed at teaching good practices for using geospatial data to address problems in environmental geography. It is based on the R language and environment, which currently provides the best option for working with diverse spatial and non-spatial data in a single platform. Fundamental techniques for processing and visualizing tabular, vector, and raster data are introduced through a series of practical examples followed by case studies that combine multiple types of data to address more complex problems. The book will have a broad audience. Both students and professionals can use it as a workbook to learn high-level techniques for geospatial data processing and analysis with R. It is also suitable as a textbook. Although not intended to provide a comprehensive introduction to R, it is designed to be accessible to readers who have at least some knowledge of coding but little to no experience with R. Key Features: Focus on developing practical workflows for processing and integrating multiple sources of geospatial data in R Example-based approach that teaches R programming and data science concepts through real-world applications related to climate, land cover and land use, and natural hazards. Consistent use of tidyverse packages for tabular data manipulation and visualization. Strong focus on analysing continuous and categorical raster datasets using the new terra package Organized so that each chapter builds on the topics and techniques covered in the preceding chapters Can be used for self-study or as the textbook for a geospatial science course.

Nation Building: Why Some Countries Come Together While Others Fall Apart (Princeton Studies in Global and Comparative Sociology)

by Andreas Wimmer

A new and comprehensive look at the reasons behind successful or failed nation buildingNation Building presents bold new answers to an age-old question. Why is national integration achieved in some diverse countries, while others are destabilized by political inequality between ethnic groups, contentious politics, or even separatism and ethnic war? Traversing centuries and continents from early nineteenth-century Europe and Asia to Africa from the turn of the twenty-first century to today, Andreas Wimmer delves into the slow-moving forces that encourage political alliances to stretch across ethnic divides and build national unity.Using datasets that cover the entire world and three pairs of case studies, Wimmer’s theory of nation building focuses on slow-moving, generational processes: the spread of civil society organizations, linguistic assimilation, and the states’ capacity to provide public goods. Wimmer contrasts Switzerland and Belgium to demonstrate how the early development of voluntary organizations enhanced nation building; he examines Botswana and Somalia to illustrate how providing public goods can bring diverse political constituencies together; and he shows that the differences between China and Russia indicate how a shared linguistic space may help build political alliances across ethnic boundaries.Wimmer then reveals, based on the statistical analysis of large-scale datasets, that these mechanisms are at work around the world and explain nation building better than competing arguments such as democratic governance or colonial legacies. He also shows that when political alliances crosscut ethnic divides and when most ethnic communities are represented at the highest levels of government, the general populace will identify with the nation and its symbols, further deepening national political integration.Offering a long-term historical perspective and global outlook, Nation Building sheds important new light on the challenges of political integration in diverse countries.

Control and Optimization with PDE Constraints (International Series of Numerical Mathematics #164)

by Gregory Von Winckel Karl Kunisch Christian Clason Kristian Bredies

Many mathematical models of physical, biological and social systems involve partial differential equations (PDEs). The desire to understand and influence these systems naturally leads to considering problems of control and optimization. This book presents important topics in the areas of control of PDEs and of PDE-constrained optimization, covering the full spectrum from analysis to numerical realization and applications. Leading scientists address current topics such as non-smooth optimization, Hamilton-Jacobi-Bellmann equations, issues in optimization and control of stochastic partial differential equations, reduced-order models and domain decomposition, discretization error estimates for optimal control problems, and control of quantum-dynamical systems. These contributions originate from the "International Workshop on Control and Optimization of PDEs" in Mariatrost in October 2011. This book is an excellent resource for students and researchers in control or optimization of differential equations. Readers interested in theory or in numerical algorithms will find this book equally useful.

Statistical Approaches to Gene x Environment Interactions for Complex Phenotypes

by Michael Windle

Findings from the Human Genome Project and from Genome-Wide Association (GWA) studies indicate that many diseases and traits manifest a more complex genomic pattern than previously assumed. These findings, and advances in high-throughput sequencing, suggest that there are many sources of influence -- genetic, epigenetic, and environmental. This volume investigates the role of the interactions of genes and environment (G × E) in diseases and traits (referred to by the contributors as complex phenotypes) including depression, diabetes, obesity, and substance use. The contributors first present different statistical approaches or strategies to address G × E and G × G interactions with high-throughput sequenced data, including two-stage procedures to identify G × E and G × G interactions, marker-set approaches to assessing interactions at the gene level, and the use of a partial-least square (PLS) approach. The contributors then turn to specific complex phenotypes, research designs, or combined methods that may advance the study of G × E interactions, considering such topics as randomized clinical trials in obesity research, longitudinal research designs and statistical models, and the development of polygenic scores to investigate G × E interactions.ContributorsFatima Umber Ahmed, Yin-Hsiu Chen, James Y.

Infinity in Early Modern Philosophy (The\new Synthese Historical Library #76)

by Reed Winegar Ohad Nachtomy

This volume contains essays that examine infinity in early modern philosophy. The essays not only consider the ways that key figures viewed the concept. They also detail how these different beliefs about infinity influenced major philosophical systems throughout the era. These domains include mathematics, metaphysics, epistemology, ethics, science, and theology.Coverage begins with an introduction that outlines the overall importance of infinity to early modern philosophy. It then moves from a general background of infinity (before early modern thought) up through Kant. Readers will learn about the place of infinity in the writings of key early modern thinkers. The contributors profile the work of Descartes, Spinoza, Leibniz, and Kant. Debates over infinity significantly influenced philosophical discussion regarding the human condition and the extent and limits of human knowledge. Questions about the infinity of space, for instance, helped lead to the introduction of a heliocentric solar system as well as the discovery of calculus. This volume offers readers an insightful look into all this and more. It provides a broad perspective that will help advance the present state of knowledge on this important but often overlooked topic.

Forecasting from Multi-equation Econometric Micromodels (Contributions to Economics)

by Jerzy Witold Wiśniewski

Forecasting from multi-equation models has very rarely been the focus in econometric literature. In response, this book presents a range of methodologies to approach this complex field and offers readers essential information on forecasting from multi-equation econometric micromodels.In the twentieth century, significant interest in econometric macromodels emerged. These multi-equation models are mostly systems of interdependent equations, most often used to describe the national economies of various countries. The book analyzes econometric forecasting procedures and illustrates them with empirical examples that are based on real economic (mostly business-derived) data. The procedure of forecast building from systems of interdependent equations is presented for two categories of econometric models: models with a feedback effect and models with closed-loop links between interdependent variables. The forecasts obtained via this technique are compared with the results derived from reduced-form equations of the respective econometric model. The author also generalizes the rules of the reduced-recursive (helical, iterative) procedure application, against the backdrop of the proposed method of forecast building from reduced-form equations of systems of interdependent equations. Given its scope, the book will appeal not only to PhD students and researchers, but also undergraduate students and academics in general.

Stochastic Dynamics in Computational Biology (Frontiers in Applied Dynamical Systems: Reviews and Tutorials #8)

by Stefanie Winkelmann Christof Schütte

The aim of this book is to provide a well-structured and coherent overview of existing mathematical modeling approaches for biochemical reaction systems, investigating relations between both the conventional models and several types of deterministic-stochastic hybrid model recombinations. Another main objective is to illustrate and compare diverse numerical simulation schemes and their computational effort. Unlike related works, this book presents a broad scope in its applications, from offering a detailed introduction to hybrid approaches for the case of multiple population scales to discussing the setting of time-scale separation resulting from widely varying firing rates of reaction channels. Additionally, it also addresses modeling approaches for non well-mixed reaction-diffusion dynamics, including deterministic and stochastic PDEs and spatiotemporal master equations. Finally, by translating and incorporating complex theory to a level accessible to non-mathematicians, this book effectively bridges the gap between mathematical research in computational biology and its practical use in biological, biochemical, and biomedical systems.
