Understanding the Context of Cognitive Aging: Mexico and the United States
by Jacqueline L. Angel Mariana López Ortega Luis Miguel Gutiérrez RobledoThis book provides a bi-national portrait of dementia in the rapidly aging Mexican-origin population in Mexico and the United States. It provides a comprehensive overview of critical conceptual and methodological issues in the study of cognitive aging and related mental and physical conditions. The book examines the sources of vulnerability and their consequences for Mexican-origin and for “aging in place”. By providing a combination of new knowledge, empirical evidence, and fresh approaches of dementia support in later life, this book will contribute to moving the field of Mexican-origin aging and health forward. By focusing on the serious challenges in old-age support for older people with dementia and neurocognitive disorders in two different contexts, this book will deepen academics, researchers, students and young investigators understanding of what is necessary to achieve optional care.
Understanding the Enrichment of Heavy Elements by the Chemodynamical Evolution Models of Dwarf Galaxies (Springer Theses)
by Yutaka HiraiThis book addresses the mechanism of enrichment of heavy elements in galaxies, a long standing problem in astronomy. It mainly focuses on explaining the origin of heavy elements by performing state-of-the-art, high-resolution hydrodynamic simulations of dwarf galaxies. In this book, the author successfully develops a model of galactic chemodynamical evolution by means of which the neutron star mergers can be used to explain the observed abundance pattern of the heavy elements synthesized by the rapid neutron capture process, such as europium, gold, and uranium in the Local Group dwarf galaxies. The book argues that heavy elements are significant indicators of the evolutionary history of the early galaxies, and presents theoretical findings that open new avenues to understanding the formation and evolution of galaxies based on the abundance of heavy elements in metal-poor stars.
Understanding the Generality of Mathematical Statements: An Experimental Study at the Transition from School to University (Bielefelder Schriften zur Didaktik der Mathematik #15)
by Milena DamrauIn this open access book Milena Damrau investigates the understanding of generality of mathematical statements in first-year university students and its relation to other proof-related activities. Through an experimental study, she particularly analyses the effect of different types of arguments (empirical, generic, and ordinary proofs) and statements (familiar and unfamiliar, as well as true and false ones) on several proof-related activities. The results reveal students' struggles with the concept of generality, how their understanding of generality is related to proof reading and construction and how different types of arguments and statements impact students’ performance in other proof-related activities. The findings offer valuable insights for improving mathematics courses at the transition from school to university and highlight the need for more experimental studies in mathematics education.
Understanding the Infinite
by Shaughan LavineHow can the infinite, a subject so remote from our finite experience, be an everyday tool for the working mathematician? Blending history, philosophy, mathematics, and logic, Shaughan Lavine answers this question with exceptional clarity. Making use of the mathematical work of Jan Mycielski, he demonstrates that knowledge of the infinite is possible, even according to strict standards that require some intuitive basis for knowledge.
Understanding the Mathematical Way of Thinking – The Registers of Semiotic Representations
by Raymond DuvalIn this book, Raymond Duval shows how his theory of registers of semiotic representation can be used as a tool to analyze the cognitive processes through which students develop mathematical thinking. To Duval, the analysis of mathematical knowledge is in its essence the analysis of the cognitive synergy between different kinds of semiotic representation registers, because the mathematical way of thinking and working is based on transformations of semiotic representations into others. Based on this assumption, he proposes the use of semiotics to identify and develop the specific cognitive processes required to the acquisition of mathematical knowledge. In this volume he presents a method to do so, addressing the following questions:• How to situate the registers of representation regarding the other semiotic “theories” • Why use a semio-cognitive analysis of the mathematical activity to teach mathematics • How to distinguish the different types of registers • How to organize learning tasks and activities which take into account the registers of representation • How to make an analysis of the students’ production in terms of registersBuilding upon the contributions he first presented in his classic book Sémiosis et pensée humaine, in this volume Duval focuses less on theoretical issues and more on how his theory can be used both as a tool for analysis and a working method to help mathematics teachers apply semiotics to their everyday work. He also dedicates a complete chapter to show how his theory can be applied as a new strategy to teach geometry.“Understanding the Mathematical Way of Thinking – The Registers of Semiotic Representations is an essential work for mathematics educators and mathematics teachers who look for an introduction to Raymond Duval’s cognitive theory of semiotic registers of representation, making it possible for them to see and teach mathematics with fresh eyes.”Professor Tânia M. M. Campos, PHD.

Understanding the Origin of Matter: Perspectives in Quantum Chromodynamics (Lecture Notes in Physics #999)
by David Blaschke Krzysztof Redlich Chihiro Sasaki Ludwik TurkoThis book aims at providing a solid basis for the education of the next generation of researchers in hot, dense QCD (Quantum ChromoDynamics) matter. This is a rapidly growing field at the interface of the smallest, i.e. subnuclear physics, and the largest scales, namely astrophysics and cosmology. The extensive lectures presented here are based on the material used at the training school of the European COST action THOR (Theory of hot matter in relativistic heavy-ion collisions).The book is divided in three parts covering ultrarelativistic heavy-ion collisions, several aspects related to QCD, and simulations of QCD and heavy-ion collisions. The scientific tools and methods discussed provide graduate students with the necessary skills to understand the structure of matter under extreme conditions of high densities, temperatures, and strong fields in the collapse of massive stars or a few microseconds after the big bang. In addition to the theory, the set of lectures presents hands-on material that includes an introduction to simulation programs for heavy-ion collisions, equations of state, and transport properties.
Understanding the Physics of Particle Accelerators: A Guide to Beam Dynamics Simulations Using ZGOUBI (Particle Acceleration and Detection)
by François MéotThis open access book introduces readers to the physics of particle accelerators, by means of beam dynamics simulations and exercises using the computer code ZGOUBI. The respective chapters are organized chronologically and trace the historical development of accelerators from electrostatic columns to storage rings, to the numerous variations on resonant acceleration and focusing techniques, while also addressing side aspects such as synchrotron radiation and spin dynamics. The book offers computer simulations in which readers can manipulate, guide, and accelerate charged particles and particle beams in most types of particle accelerator. By performing these simulation exercises, they will acquire a deeper understanding of charged particle beam optics, accelerator physics and technology, as well as the why and how of when to use one technology or the other. These exercises guide readers through a virtual world of accelerator and beam simulations, and involve e.g. manipulating beams for cancer therapy, producing synchrotron radiation for condensed matter research, accelerating polarized ion beams for nuclear physics research, etc. In addition to acquiring an enhanced grasp of physics, readers will discover the basic theoretical and practical aspects of particle accelerators’ main components: guiding and focusing magnets, radio-wave accelerating cavities, wigglers, etc.
Understanding the Quality Use of Research Evidence in Education: What It Means to Use Research Well
by Mark Rickinson Lucas Walsh Joanne Gleeson Blake Cutler Connie Cirkony Mandy SalisburyThis book focuses on the question of how to understand quality use of research evidence in education, or what it means to use research evidence well. Internationally there are widespread efforts to increase the use of research evidence within educational policy and practice. Such efforts raise important questions about how we understand not just the quality of evidence, but also the quality of its use. To date, there has been wide-ranging debate about the former, but very little dialogue about the latter. Based on a five-year study with schools and school systems in Australia, this book sheds new light on: why clarity about quality of use is critical to educational improvement; how quality use of research evidence can be framed in education; what using research well involves and looks like in practice; what quality research use means for individuals, organisations and systems; and what aspects of using research well still need to be better understood. This book will be an invaluable resource for professionals within and beyond education who want to better understand what using research evidence well means and involves and how it can be supported.

Understanding Uncertainty (Wiley Series in Probability and Statistics)
by Dennis V. LindleyPraise for the First Edition"...a reference for everyone who is interested in knowing and handling uncertainty."--Journal of Applied StatisticsThe critically acclaimed First Edition of Understanding Uncertainty provided a study of uncertainty addressed to scholars in all fields, showing that uncertainty could be measured by probability, and that probability obeyed three basic rules that enabled uncertainty to be handled sensibly in everyday life. These ideas were extended to embrace the scientific method and to show how decisions, containing an uncertain element, could be rationally made.Featuring new material, the Revised Edition remains the go-to guide for uncertainty and decision making, providing further applications at an accessible level including:A critical study of transitivity, a basic concept in probabilityA discussion of how the failure of the financial sector to use the proper approach to uncertainty may have contributed to the recent recessionA consideration of betting, showing that a bookmaker's odds are not expressions of probabilityApplications of the book's thesis to statisticsA demonstration that some techniques currently popular in statistics, like significance tests, may be unsound, even seriously misleading, because they violate the rules of probabilityUnderstanding Uncertainty, Revised Edition is ideal for students studying probability or statistics and for anyone interested in one of the most fascinating and vibrant fields of study in contemporary science and mathematics.

Understanding Vector Calculus: Practical Development and Solved Problems (Dover Books on Mathematics)
by Jerrold FranklinThis concise text was created as a workbook for learning to use vector calculus in practical calculations and derivations. Its only prerequisite is a familiarity with one-dimensional differential and integral calculus. Though it often makes use of physical examples, knowledge of physics itself is not required to study the mathematics of vector calculus. The approach is suitable for advanced undergraduates and graduate students in mathematics, physics, and other areas of science. The two-part treatment opens with a brief text that develops vector calculus from the very beginning and then addresses some more detailed applications. Topics include vector differential operators, vector identities, integral theorems, Dirac delta function, Green's functions, general coordinate systems, and dyadics. The second part consists of answered problems, all closely related to the development of vector calculus in the text. Those who study this book and work out the problems will find that rather than memorizing long equations or consulting references, they will be able to work out calculations as they go.

Undiluted Hocus-Pocus: The Autobiography of Martin Gardner
by Martin GardnerThe autobiography of the beloved writer who inspired a generation to study math and scienceMartin Gardner wrote the Mathematical Games column for Scientific American for twenty-five years and published more than seventy books on topics as diverse as magic, religion, and Alice in Wonderland. Gardner's illuminating autobiography is a candid self-portrait by the man evolutionary theorist Stephen Jay Gould called our "single brightest beacon" for the defense of rationality and good science against mysticism and anti-intellectualism.Gardner takes readers from his childhood in Oklahoma to his varied and wide-ranging professional pursuits. He shares colorful anecdotes about the many fascinating people he met and mentored, and voices strong opinions on the subjects that matter to him most, from his love of mathematics to his uncompromising stance against pseudoscience. For Gardner, our mathematically structured universe is undiluted hocus-pocus—a marvelous enigma, in other words.Undiluted Hocus-Pocus offers a rare, intimate look at Gardner’s life and work, and the experiences that shaped both.
Undocumented Migration
by Roberto G. Gonzales Nando Sigona Anna Papoutsi Martha C. FrancoUndocumented migration is a global and yet elusive phenomenon. Despite contemporary efforts to patrol national borders and mass deportation programs, it remains firmly placed at the top of the political agenda in many countries where it receives hostile media coverage and generates fierce debate. However, as this much-needed book makes clear, unauthorized movement should not be confused or crudely assimilated with the social reality of growing numbers of large, settled populations lacking full citizenship and experiencing precarious lives. From the journeys migrants take to the lives they seek on arrival and beyond, Undocumented Migration provides a comparative view of how this phenomenon plays out, looking in particular at the United States and Europe. Drawing on their extensive expertise, the authors breathe life into the various issues and debates surrounding migration, including the experiences and voices of migrants themselves, to offer a critical analysis of a hidden and too often misrepresented population.
Undocumented Secrets of MATLAB-Java Programming
by Yair M. AltmanFor a variety of reasons, the MATLAB-Java interface was never fully documented. This is really quite unfortunate: Java is one of the most widely used programming languages, having many times the number of programmers and programming resources as MATLAB. Also unfortunate is the popular claim that while MATLAB is a fine programming platform for proto

Uneducated Guesses: Using Evidence to Uncover Misguided Education Policies
by Howard WainerWhat statistical evidence shows us about our misguided educational policiesUneducated Guesses challenges everything our policymakers thought they knew about education and education reform, from how to close the achievement gap in public schools to admission standards for top universities. In this explosive book, Howard Wainer uses statistical evidence to show why some of the most widely held beliefs in education today—and the policies that have resulted—are wrong. He shows why colleges that make the SAT optional for applicants end up with underperforming students and inflated national rankings, and why the push to substitute achievement tests for aptitude tests makes no sense. Wainer challenges the thinking behind the enormous rise of advanced placement courses in high schools, and demonstrates why assessing teachers based on how well their students perform on tests—a central pillar of recent education reforms—is woefully misguided. He explains why college rankings are often lacking in hard evidence, why essay questions on tests disadvantage women, why the most grievous errors in education testing are not made by testing organizations—and much more.No one concerned about seeing our children achieve their full potential can afford to ignore this book. With forceful storytelling, wry insight, and a wealth of real-world examples, Uneducated Guesses exposes today's educational policies to the light of empirical evidence, and offers solutions for fairer and more viable future policies.
The Unfinished Game: Pascal, Fermat, and the Seventeenth-Century Letter that Made the World Modern
by Keith DevlinIn the early seventeenth century, the outcome of something as simple as a dice roll was consigned to the realm of unknowable chance. Mathematicians largely agreed that it was impossible to predict the probability of an occurrence. Then, in 1654, Blaise Pascal wrote to Pierre de Fermat explaining that he had discovered how to calculate risk. The two collaborated to develop what is now known as probability theory?a concept that allows us to think rationally about decisions and events. In "The Unfinished Game," Keith Devlin masterfully chronicles Pascal and FermatOCOs mathematical breakthrough, connecting a centuries-old discovery with its remarkable impact on the modern world.

Unified Growth Theory
by Oded GalorFor most of the vast span of human history, economic growth was all but nonexistent. Then, about two centuries ago, some nations began to emerge from this epoch of economic stagnation, experiencing sustained economic growth that led to significant increases in standards of living and profoundly altered the level and distribution of wealth, population, education, and health across the globe. The question ever since has been--why? This is the first book to put forward a unified theory of economic growth that accounts for the entire growth process, from the dawn of civilization to today. Oded Galor, who founded the field of unified growth theory, identifies the historical and prehistorical forces behind the differential transition timing from stagnation to growth and the emergence of income disparity around the world. Galor shows how the interaction between technological progress and population ultimately raised the importance of education in coping with the rapidly changing technological environment, brought about significant reduction in fertility rates, and enabled some economies to devote greater resources toward a steady increase in per capita income, paving the way for sustained economic growth. Presents a unified theory of economic growth from the dawn of civilization to today Explains the worldwide disparities in living standards and population we see today Provides a comprehensive overview of the three phases of the development process Analyzes the Malthusian theory and its empirical support Examines theories of demographic transition and their empirical significance Explores the interaction between economic development and human evolution
Unified Lagrangian Formulation for Fluid and Solid Mechanics, Fluid-Structure Interaction and Coupled Thermal Problems Using the PFEM
by Alessandro FranciThis book treats the derivation and implementation of a unified particle finite element formulation for the solution of fluid and solid mechanics, Fluid-Structure Interaction (FSI) and coupled thermal problems. FSI problems are involved in many engineering branches, from aeronautics to civil and biomedical engineering. The numerical method proposed in this book has been designed to deal with a large part of these. In particular, it is capable of simulating accurately free-surface fluids interacting with structures that may undergo large displacements, suffer from thermo-plastic deformations and even melt. The method accuracy has been successfully verified in several numerical examples. The thesis also contains the application of the proposed numerical strategy for the simulation of a real industrial problem. This thesis, defended at the Universitat Politecnica de Catalunya in 2015, was selected (ex aequo) as the best PhD thesis in numerical methods in Spain for the year 2015 by the Spanish Society of Numerical Methods in Engineering (SEMNI).
