Improving the Measurement of Consumer Expenditures

by Thomas F. Crossley John Sabelhaus Christopher D. Carroll

Robust and reliable measures of consumer expenditures are essential for analyzing aggregate economic activity and for measuring differences in household circumstances. Many countries, including the United States, are embarking on ambitious projects to redesign surveys of consumer expenditures, with the goal of better capturing economic heterogeneity. This is an appropriate time to examine the way consumer expenditures are currently measured, and the challenges and opportunities that alternative approaches might present. Improving the Measurement of Consumer Expenditures begins with a comprehensive review of current methodologies for collecting consumer expenditure data. Subsequent chapters highlight the range of different objectives that expenditure surveys may satisfy, compare the data available from consumer expenditure surveys with that available from other sources, and describe how the United States's current survey practices compare with those in other nations.

Improving the Measurement of Late-Life Disability in Population Surveys: Beyond ADLs and IADLs - Summary of a Workshop

by National Research Council of the National Academies

Improving the Measurement of Late-Life Disability in Population Surveys summarizes a workshop organized to draw upon recent advances to improve the measurement of physical and cognitive disability in population surveys of the elderly population. The book questions whether or not the measures of activities of daily living and instrumental activities of daily living used in many population surveys are sufficient as the primary survey-based indicators of late-life disability. If not, should they be refined or should they be supplemented by other measures of disability in surveys? If yes, in what ways should disability measures be changed or modified to produce population estimates of late-life disability and to monitor trends? The book also discusses what further research is needed to advance this effort.

In 100 Years: Leading Economists Predict the Future (The\mit Press Ser.)

by Ignacio Palacios-Huerta

In this book, ten prominent economists—including Nobel laureates and several likely laureates—offer their ideas about what the future might hold in 100 years.This pithy and engaging volume shows that economists may be better equipped to predict the future than science fiction writers. Economists' ideas, based on both theory and practice, reflect their knowledge of the laws of human interactions as well as years of experimentation and reflection. Although perhaps not as screenplay-ready as a work of fiction, these economists' predictions are ready for their close-ups. In this book, ten prominent economists—including Nobel laureates and several likely laureates—offer their ideas about the world of the twenty-second century.In scenarios that range from the optimistic to the guardedly gloomy, these thinkers consider such topics as the transformation of work and wages, the continuing increase in inequality, the economic rise of China and India, the endlessly repeating cycle of crisis and (projected) recovery, the benefits of technology, the economic consequences of political extremism, and the long-range effects of climate change. For example, 2013 Nobelist Robert Shiller provides an innovative view of future risk management methods using information technology; and Martin Weitzman raises the intriguing but alarming possibility of using geoengineering techniques to mitigate the inevitable effects of climate change.Contributors Daron Acemoglu, Angus Deaton, Avinash K.

This pithy and engaging volume shows that economists may be better equipped to predict the future than science fiction writers. Economists' ideas, based on both theory and practice, reflect their knowledge of the laws of human interactions as well as years of experimentation and reflection. Although perhaps not as screenplay-ready as a work of fiction, these economists' predictions are ready for their close-ups. In this book, ten prominent economists -- including Nobel laureates and several likely laureates -- offer their ideas about the world of the twenty-second century. In scenarios that range from the optimistic to the guardedly gloomy, these thinkers consider such topics as the transformation of work and wages, the continuing increase in inequality, the economic rise of China and India, the endlessly repeating cycle of crisis and (projected) recovery, the benefits of technology, the economic consequences of political extremism, and the long-range effects of climate change. For example, Daron Acemoglu offers a thoughtful discussion of how trends of the last century -- including uneven growth, technological integration, and resource scarcity -- might translate into the next; 2013 Nobelist Robert Shiller provides an innovative view of future risk management methods using information technology; 2012 Nobelist Alvin Roth projects his theory of Matching Markets into the next century, focusing on schools, jobs, marriage and family, and medicine; 1987 Nobelist Robert Solow considers the shift away from remunerated labor, among other subjects; and Martin Weitzman raises the intriguing but alarming possibility of using geoengineering techniques to mitigate the nevitable effects of climate change. In a 1930 essay mentioned by several contributors, "Economic Possibilities for Our Grandchildren," John Maynard Keynes offered predictions that, read today, range from absolutely correct to spectacularly wrong. This book follows in Keynes's path, hoping, perhaps, to better his average.

In Bauspielen Mathematik entdecken: Aktivitäten von Kindern mathematikdidaktisch analysieren und verstehen

by Esther Henschen

Dem Spiel mit Bauklötzen wird ein hohes mathematisches Potenzial zugesprochen und in Kindergärten sind Bauspiele eine beliebte Spielform. Warum das so ist und was das für die frühe mathematische Bildung bedeutet, gilt es zu klären. Mit dieser Veröffentlichung wird deshalb gezeigt, wie Bauspielaktivitäten von Kindern unter mathematikdidaktischer Perspektive systematisch und differenziert beschrieben werden können. Dies geschieht auf der Grundlage der Ergebnisse einer qualitativen Videoanalyse von Bauspielsituationen aus dem Alltag in verschiedenen Kindertageseinrichtungen sowie durch eine vergleichende Analyse von Texten zur Bedeutung des Bauspiels für die kindliche Entwicklung aus verschiedenen Epochen (seit 1850 bis heute) und aus verschiedenen Disziplinen (Mathematikdidaktik, Elementardidaktik, Pädagogik und Psychologie).Wie viel Mathematik im Spiel der Kinder steckt und inwiefern sich Bauspielaktivitäten als mathematische Lernchancen deuten lassen, kann durch die im Rahmen der qualitativen Videoanalyse entwickelten Kategorien aufgedeckt werden. Eine besondere Bedeutung kommt dabei der Alltagssprache der Kinder sowie der darin enthaltenen informellen Mathematik zu.

In Foreign Lands: The Migration of Scientists for Political or Economic Reasons (Trends in the History of Science)

by Maria Teresa Borgato Christine Phili

This proceedings volume collects the stories of mathematicians and scientists who have spent and developed parts of their careers and life in countries other than those of their origin. The reasons may have been different in different periods but were often driven by political or economic circumstances: The lack of suitable employment opportunities in their home countries, adverse political systems, and wars have led to the emigration of scientists. The volume shows that these movements have played an important role in spreading scientific knowledge and have often changed the scientific landscape, tradition and future of studies and research fields.The book analyses in particular: aspects of Euler’s, Lagrange’s and Boscovich’s scientific biographies, migrations of scientists from France, Spain and Greece to Russia in the eighteenth and nineteenth centuries, and from Russia to France in the twentieth century, exiles from Italy before the Italian Risorgimento, migrations inside Europe and the escape of mathematicians from Nazi-fascist Europe, between the two World Wars, as well as the mobility of experts around the world. It includes selected contributions from the symposium In Foreign Lands: The Migration of Scientists for Political or Economic Reasons held at the Conference of the International Academy of the History of Science in Athens (September 2019).

In höheren Räumen: Der Weg der Geometrie in die vierte Dimension (Mathematik im Kontext)

by Klaus Volkert

Das vorliegende Buch schildert, wie sich die Geometrie in der zweiten Hälfte des 19. Jhs. allmählich von der Beschränkung der bis dato als selbstverständlich angenommenen Einzigartigkeit und Dreidimensionalität des Raumes befreite, was die Motive hierfür waren und welche Ergebnisse erzielt wurden. Unter diesen ragt ein Topos heraus: die Bestimmung der regulären Polytope im vierdimensionalen Raum. Nicht nur innermathematisch erregte die neue Geometrie Aufsehen; der Versuch, sie zur „wissenschaftlichen“ Erklärung spiritistischer Kunststücke heranzuziehen, führte bald dazu, dass die vierte Dimension in aller Munde war. Selten hat ein mathematisches Konzept eine solche Popularität erreicht wie die vierte Dimension; ein interessantes, heute fast vergessenes Kapitel zum Thema Mathematik und Öffentlichkeit wurde aufgeblättert. Dieses Buch schildert ausführlich den „Zöllner-Skandal“, ausgelöst durch die erwähnten Erklärungsversuche des Leipziger Astrophysiker Friedrich Karl Zöllner, und die Reaktionen hierauf seitens der Mathematiker, deren Strategie sich schlagwortartig als "Zurück in den Elfenbeinturm" charakterisieren lässt. Schließlich kommen die Beziehungen der vierten Dimension zu anderen Kulturgebieten wie bildende Kunst und Literatur zur Sprache. Philosophische Aspekte sind allgegenwärtig in der Geschichte der vierten Dimension.Das Buch wendet sich an alle, die sich für die Geschichte der Mathematik und deren Einbettung in eine allgemeinere Kulturgeschichte interessieren. Es setzt wenig mehr als Schulgeometrie voraus.

In Pursuit of the Traveling Salesman

by William J. Cook

What is the shortest possible route for a traveling salesman seeking to visit each city on a list exactly once and return to his city of origin? It sounds simple enough, yet the traveling salesman problem is one of the most intensely studied puzzles in applied mathematics--and it has defied solution to this day. In this book, William Cook takes readers on a mathematical excursion, picking up the salesman's trail in the 1800s when Irish mathematician W. R. Hamilton first defined the problem, and venturing to the furthest limits of today's state-of-the-art attempts to solve it. Cook examines the origins and history of the salesman problem and explores its many important applications, from genome sequencing and designing computer processors to arranging music and hunting for planets. He looks at how computers stack up against the traveling salesman problem on a grand scale, and discusses how humans, unaided by computers, go about trying to solve the puzzle. Cook traces the salesman problem to the realms of neuroscience, psychology, and art, and he also challenges readers to tackle the problem themselves. The traveling salesman problem is--literally--a $1 million question. That's the prize the Clay Mathematics Institute is offering to anyone who can solve the problem or prove that it can't be done. In Pursuit of the Traveling Salesman travels to the very threshold of our understanding about the nature of complexity, and challenges you yourself to discover the solution to this captivating mathematical problem.

In Pursuit of Zeta-3: The World's Most Mysterious Unsolved Math Problem

by Paul J. Nahin

An engrossing look at the history and importance of a centuries-old but still unanswered math problemFor centuries, mathematicians the world over have tried, and failed, to solve the zeta-3 problem. Math genius Leonhard Euler attempted it in the 1700s and came up short. The straightforward puzzle considers if there exists a simple symbolic formula for the following: 1+(1/2)^3+(1/3)^3+(1/4)^3+. . . . But why is this issue—the sum of the reciprocals of the positive integers cubed—so important? With In Pursuit of Zeta-3, popular math writer Paul Nahin investigates the history and significance of this mathematical conundrum.Drawing on detailed examples, historical anecdotes, and even occasionally poetry, Nahin sheds light on the richness of the nature of zeta-3. He shows its intimate connections to the Riemann hypothesis, another mathematical mystery that has stumped mathematicians for nearly two centuries. He looks at its links with Euler’s achievements and explores the modern research area of Euler sums, where zeta-3 occurs frequently. An exact solution to the zeta-3 question wouldn’t simply satisfy pure mathematical interest: it would have critical ramifications for applications in physics and engineering, such as quantum electrodynamics. Challenge problems with detailed solutions and MATLAB code are included at the end of each of the book’s sections.Detailing the trials and tribulations of mathematicians who have approached one of the field’s great unsolved riddles, In Pursuit of Zeta-3 will tantalize curious math enthusiasts everywhere.

In Situ Visualization for Computational Science (Mathematics and Visualization)

by Hank Childs Janine C. Bennett Christoph Garth

This book provides an overview of the emerging field of in situ visualization, i.e. visualizing simulation data as it is generated. In situ visualization is a processing paradigm in response to recent trends in the development of high-performance computers. It has great promise in its ability to access increased temporal resolution and leverage extensive computational power. However, the paradigm also is widely viewed as limiting when it comes to exploration-oriented use cases. Furthermore, it will require visualization systems to become increasingly complex and constrained in usage. As research efforts on in situ visualization are growing, the state of the art and best practices are rapidly maturing.Specifically, this book contains chapters that reflect state-of-the-art research results and best practices in the area of in situ visualization. Our target audience are researchers and practitioners from the areas of mathematics computational science, high-performance computing, and computer science that work on or with in situ techniques, or desire to do so in future.
