Your Statistical Consultant: Answers to Your Data Analysis Questions
by Dr Rae R. Newton Dr Kjell Erik RudestamAlthough many graduate students and researchers have had course work in statistics, they sometimes find themselves stumped in proceeding with a particular data analysis question. In fact, statistics is often taught as a lesson in mathematics as opposed to a strategy for answering questions about world[?], leaving beginning researchers at a loss for how to proceed. In these situations, it is common to turn to a statistical expert, the "go to" person when questions regarding appropriate data analysis emerge. Your Statistical Consultant is an authentic alternative resource for describing, explaining, and making recommendations regarding thorny or confusing statistical issues. Written to be responsive to a wide range of inquiries and levels of expertise, this book is flexibly organized so readers can either read it sequentially or turn directly to the sections that correspond to their concerns and questions.
You're the Umpire: Mind-Boggling Questions to Test Your Baseball Knowledge
by Wayne StewartDo you think you have what it takes to be a Major League umpire? Well, now you can test your knowledge of the game with Wayne Stewart’s You’re the Umpire. Divided into three sections, this unusual handbook, now in its third edition, offers Routine Calls, which deal with scenarios and rules that typically come up in games and deal with clear-cut rules—fair and foul, strike zone questions, and the like. The next section, Basic Situations, deals with umpiring matters and rules that are just a bit more unusual or, for the casual fan, obscure. Interference and obstruction calls, for example, don’t come up too often, but they remain standard stuff involving rules that umps and many fans know quite well. In the final section, Obscure Rules and Situations, you will be presented with what many baseball people call “knotty” problems. Here, you will be asked questions involving the complex infield fly rule and other arcane matters. This section, then, is the ultimate test of your umpiring skills and knowledge. Most of the situations in You’re the Umpire come from real games, such as the time a fastball from Randy Johnson killed a bird in flight and what the umps did regarding that pitch, but some scenarios are made up to illustrate specific points or rules. Test yourself against your friends or against the iconic baseball rulebook. It’s a challenge and it’s fun.

Youth in India: Aspirations, Attitudes, Anxieties
by Sanjay KumarThis book explores the attitudes, anxieties and aspirations of India’s burgeoning young population in a globalised world. Drawing upon time-series survey data of the Indian youth aged between 15 and 34 years across 19 Indian states, it provides key insights into a range of themes along with an overview of the changing trends and patterns of their behaviour. The volume examines the job preferences of the Indian youth, their career priorities and opinions on reservations in employment and education sectors. It measures their degree of political participation and studies their attitude regarding political issues. It looks at aspects relating to their social and cultural contexts, preferences and practices, including lifestyle choices, consumption habits and social customs such as marriage, as they negotiate between tradition and modernity. Further, it discusses the anxieties and insecurities that the youth face, their mental health and their experiences of social discrimination. The essays here offer an understanding of a critical demographic and shed light on the challenges and opportunities that the Indian youth confront today. Lucid, accessible and empirically grounded, this volume will be useful to scholars and researchers of sociology, political sociology, political studies, youth psychology and anthropology as well as policymakers, journalists and the interested general reader.
The Yugoslav Economic System (Routledge Revivals): The First Labor-Managed Economy in the Making
by Branko HorvatFirst published in 1976, this book traces the development of the Yugoslav economy from the end of the Second World War to the beginning of 1975, which the author argues was a highly productive era of social innovation. Drawing on personal experience of the Revolution, the Partisan Liberation War and his time as a member of the Federal Planning Board as well as a comprehensive array of written sources, the author attempts to understand the development process, compare policy proclamations with achieved results, study the theories and ideas that led a to certain policy, distinguish the economic and political ingredients in decision making and analyses the causes of success and failure.

Z Boson Transverse Momentum Distribution, and ZZ and WZ Production
by Mika VesterinenThis work develops novel data analysis techniques enabling aspects of the Standard Model of particle physics to be tested with unprecedented precision using data from the DZero experiment at the high energy "Tevatron" proton-antiproton collider at Fermilab, Chicago. Vesterinen's measurements of the transverse momentum of Z bosons using the novel variable φ* have exposed deficiencies in the current state-of-the-art theoretical predictions for vector boson production at hadron colliders. These techniques are now being used in the experiments at CERN's Large Hadron Collider (LHC) and have stimulated considerable interest in the theoretical particle physics community. Furthermore, Vesterinen's measurements of the cross sections for the production of pairs of vector bosons (WZ and ZZ) are to date the most precise ever made.

Zainichi Korean Identity and Ethnicity (Routledge Contemporary Japan Series #10)
by David ChapmanShedding light on contemporary Japanese society in an international context, Japanese-Korean relations and modern day notions of a multicultural Japan, this book addresses the broad notions and questions of citizenship, identity, ethnicity and belonging through investigation of Japan’s Korean population (zainichi). Despite zainichi Korean existence being integral to, and interwoven with, recent Japanese social history, the debates and discussions of the Korean community in Japan have been largely ignored. Moreover, as a post colonial context, the zainichi Korean situation has drawn scant attention and little investigation outside of Japan. In Zainichi Korean Ethnicity and Identity David Chapman seeks to redress this balance, engaging with recent discourse from within Japan’s Korean population. By taking a close look at how exclusion, marginalisation and privilege work, the book brings insight into the mechanisms of discrimination, and how discourse not only marginalizes individuals and groups, but also how it can create social change and enhance the sense of self. This book will be of interest to students and scholars of Asian studies and of Japanese and Korean politics, culture and society, but also to those with a broader interest in migration studies and the study of identity and ethnicity.
The Zakharov System and its Soliton Solutions
by Boling Guo Zaihui Gan Linghai Kong Jingjun ZhangThis book focuses on the theory of the Zakharov system in the context of plasma physics. It has been over 40 years since the system was first derived by V. E. Zakharov - and in the course of those decades, many innovative achievements with major impacts on other research fields have been made. The book represents a first attempt to highlight the mathematical theories that are most important to researchers, including the existence and unique problems, blow-up, low regularity, large time behavior and the singular limit. Rather than attempting to examine every aspect of the Zakharov system in detail, it provides an effective road map to help readers access the frontier of studies on this system.

Zeit und das Potential ihrer Darstellungsformen: Eine Handreichung zur Anschaulichkeit der Zeit für das Grundschullehramt (MINTUS – Beiträge zur mathematisch-naturwissenschaftlichen Bildung)
by Philipp RaackDie Zeit ist ein rätselhaftes und vielschichtiges Naturphänomen. Auf dem menschheitsgeschichtlichen Weg die Zeit besser zu verstehen und mit ihr umzugehen, ist auch immer ihre Visualisierung von alltagspraktischer Bedeutung gewesen. Aus der Perspektive des Grundschullehramts konzentriert sich das fachdidaktisch-pädagogische Anliegen dieser Arbeit auf die Veranschaulichungen der Zeit. Zum einen sind dies die subjektive und objektive Zeit, analoge und digitale Uhrzeitformate und lineare und zyklische Zeitdarstellungsformen. Diese drei großen, teils komplementär zu begreifenden Begriffspaare stellen den Kern der Arbeit dar, die sich unter anderem auch in der durchexerzierten Befragung von Sachunterrichtsstudierenden und in einer umfangreichen Schulbuchanalyse widerspiegeln. Darüber hinaus werden eine Vielzahl an didaktisch wertvollen Abbildungen angeboten, die vor allem Anwärter*innen des Grundschullehramtes für abstrakte Aspekte des Themas Zeit in der Grundschule sensibilisieren soll.
The Zen of Magic Squares, Circles, and Stars: An Exhibition of Surprising Structures across Dimensions
by Clifford A. PickoverHumanity's love affair with mathematics and mysticism reached a critical juncture, legend has it, on the back of a turtle in ancient China. As Clifford Pickover briefly recounts in this enthralling book, the most comprehensive in decades on magic squares, Emperor Yu was supposedly strolling along the Yellow River one day around 2200 B.C. when he spotted the creature: its shell had a series of dots within squares. To Yu's amazement, each row of squares contained fifteen dots, as did the columns and diagonals. When he added any two cells opposite along a line through the center square, like 2 and 8, he always arrived at 10. The turtle, unwitting inspirer of the ''Yu'' square, went on to a life of courtly comfort and fame. Pickover explains why Chinese emperors, Babylonian astrologer-priests, prehistoric cave people in France, and ancient Mayans of the Yucatan were convinced that magic squares--arrays filled with numbers or letters in certain arrangements--held the secret of the universe. Since the dawn of civilization, he writes, humans have invoked such patterns to ward off evil and bring good fortune. Yet who would have guessed that in the twenty-first century, mathematicians would be studying magic squares so immense and in so many dimensions that the objects defy ordinary human contemplation and visualization? Readers are treated to a colorful history of magic squares and similar structures, their construction, and classification along with a remarkable variety of newly discovered objects ranging from ornate inlaid magic cubes to hypercubes. Illustrated examples occur throughout, with some patterns from the author's own experiments. The tesseracts, circles, spheres, and stars that he presents perfectly convey the age-old devotion of the math-minded to this Zenlike quest. Number lovers, puzzle aficionados, and math enthusiasts will treasure this rich and lively encyclopedia of one of the few areas of mathematics where the contributions of even nonspecialists count.
Zeno's Paradox
by Joseph MazurThe fascinating story of an ancient riddle?and what it reveals about the nature of time and space Three millennia ago, the Greek philosopher Zeno constructed a series of logical paradoxes to prove that motion is impossible. Today, these paradoxes remain on the cutting edge of our investigations into the fabric of space and time. Zeno?s Paradox uses the motion paradox as a jumping-off point for an exploration of the twenty-five-hundred-year quest to uncover the true nature of the universe. From Galileo to Einstein to Stephen Hawking, some of the greatest minds in history have tackled the problem and made spectacular breakthroughs?but through it all, the paradox of motion remains. .
Zero: The Biography of a Dangerous Idea
by Charles SeifeThe Babylonians invented it, the Greeks banned it, the Hindus worshiped it, and the Church used it to fend off heretics. Now it threatens the foundations of modern physics. For centuries the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything. In Zero, Science Journalist Charles Seife follows this innocent-looking number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe, its rise and transcendence in the West, and its ever-present threat to modern physics. Here are the legendary thinkers—from Pythagoras to Newton to Heisenberg, from the Kabalists to today's astrophysicists—who have tried to understand it and whose clashes shook the foundations of philosophy, science, mathematics, and religion. Zero has pitted East against West and faith against reason, and its intransigence persists in the dark core of a black hole and the brilliant flash of the Big Bang. Today, zero lies at the heart of one of the biggest scientific controversies of all time: the quest for a theory of everything. .
Zero Is The Leaves On The Tree
by Betsy Franco Shino AriharaIt's easy to count three of something-- just add them up. But how do you count zero, a number that is best defined by what it's not?Can you see it?Can you hear it?Can you feel it?This important math concept is beautifully explored in a way that will inspire children to find zero everywhere--from the branches of a tree by day to the vast, starry sky by night.

The book is intended for researchers and graduate students in ring theory, Banach algebra theory, and nonassociative algebra.
Zero-Sum Discrete-Time Markov Games with Unknown Disturbance Distribution: Discounted and Average Criteria (SpringerBriefs in Probability and Mathematical Statistics)
by J. Adolfo Minjárez-SosaThis SpringerBrief deals with a class of discrete-time zero-sum Markov games with Borel state and action spaces, and possibly unbounded payoffs, under discounted and average criteria, whose state process evolves according to a stochastic difference equation. The corresponding disturbance process is an observable sequence of independent and identically distributed random variables with unknown distribution for both players. Unlike the standard case, the game is played over an infinite horizon evolving as follows. At each stage, once the players have observed the state of the game, and before choosing the actions, players 1 and 2 implement a statistical estimation process to obtain estimates of the unknown distribution. Then, independently, the players adapt their decisions to such estimators to select their actions and construct their strategies. This book presents a systematic analysis on recent developments in this kind of games. Specifically, the theoretical foundations on the procedures combining statistical estimation and control techniques for the construction of strategies of the players are introduced, with illustrative examples. In this sense, the book is an essential reference for theoretical and applied researchers in the fields of stochastic control and game theory, and their applications.
Zero, Zilch, Nada: Counting to None
by Wendy UlmerHarry is excited! Today is the first day at his new job at the 4 Color Balloon Factory. Harry loves balloons almost more than anything! When Mr. Huffy, his new boss, tells him to blow up 100 balloons for Mrs. Doopido's birthday party, Harry can't wait to get started. But when Harry wants to make sure he has the correct number of balloons for the birthday party, counting the balloons gets confusing. And no matter what he does, the number still comes out wrong. What is the best way to count to 100?
Zeros of Polynomials and Solvable Nonlinear Evolution Equations
by Francesco CalogeroReporting a novel breakthrough in the identification and investigation of solvable and integrable nonlinearly coupled evolution ordinary differential equations (ODEs) or partial differential equations (PDEs), this text includes practical examples throughout to illustrate the theoretical concepts. Beginning with systems of ODEs, including second-order ODEs of Newtonian type, it then discusses systems of PDEs, and systems evolving in discrete time. It reports a novel, differential algorithm which can be used to evaluate all the zeros of a generic polynomial of arbitrary degree: a remarkable development of a fundamental mathematical problem with a long history. The book will be of interest to applied mathematicians and mathematical physicists working in the area of integrable and solvable non-linear evolution equations; it can also be used as supplementary reading material for general applied mathematics or mathematical physics courses.
