The impact of the Cold War is still being felt around the world today. This insightful single-volume reference captures the events and personalities of the era, while also inspiring critical thinking about this still-controversial period. Cold War: The Essential Reference Guide is intended to introduce students to the tensions between the Soviet Union and the United States that dominated international affairs in the second half of the 20th century. A comprehensive overview essay, plus separate essays on the causes and consequences of the conflict, will provide readers with the necessary context to understand the many facets of this complex era. The guide's expert contributors cover all of the influential people and pivotal events of the period, encompassing the United States, the Soviet Union, Europe, Southeast Asia, China, the Middle East, Latin America, and Africa from political, military, and cultural perspectives. Reference entries offer valuable insight into the leaders and conflicts that defined the Cold War, while other essays promote critical thinking about controversial and significant Cold War topics, including whether Ronald Reagan was responsible for ending the Cold War, the impact of Sputnik on the Cold War, and the significance of the Prague Spring.
Providing an indispensable resource for students and policy makers investigating the Bosnian catastrophes of the 1990s, this book provides a comprehensive survey of the leaders, ideas, movements, and events pertaining to one of the most devastating conflicts of contemporary times. In the three years of the Bosnian War, well over 100,000 people lost their lives, amid intense carnage. This led to unprecedented criminal prosecutions for genocide, war crimes, and crimes against humanity that are still taking place today. Bosnian Genocide: The Essential Reference Guide is the first encyclopedic treatment of the Balkan conflicts of the period from 1991 to 1999. It provides broad coverage of the nearly decade-long conflict, but with a major focus on the Bosnian War of 1992–1995. The book examines a variety of perspectives of the conflicts relating to Slovenia, Croatia, Bosnia-Herzegovina, Serbia, and Kosovo, among other developments that took place during the years spotlighted. The entries consider not only the leaders, ideas, movements, and events relating to the Bosnian War of 1992–1995 but also examine themes from before the war and after it. As such, coverage continues through to the Kosovo Intervention of 1999, arguing that this event, too, was part of the conflict that purportedly ended in 1995. This work will serve university students undertaking the study of genocide in the modern world and readers interested in modern wars, international crisis management, and peacekeeping and peacemaking.
The high-level language of R is recognized as one of the mostpowerful and flexible statistical software environments, and israpidly becoming the standard setting for quantitative analysis,statistics and graphics. R provides free access to unrivalledcoverage and cutting-edge applications, enabling the user to applynumerous statistical methods ranging from simple regression to timeseries or multivariate analysis. Building on the success of the author’s bestsellingStatistics: An Introduction using R, The R Book ispacked with worked examples, providing an all inclusive guide to R,ideal for novice and more accomplished users alike. The bookassumes no background in statistics or computing and introduces theadvantages of the R environment, detailing its applications in awide range of disciplines. Provides the first comprehensive reference manual for the Rlanguage, including practical guidance and full coverage of thegraphics facilities. Introduces all the statistical models covered by R, beginningwith simple classical tests such as chi-square and t-test. Proceeds to examine more advance methods, from regression andanalysis of variance, through to generalized linear models,generalized mixed models, time series, spatial statistics,multivariate statistics and much more. The R Book is aimed at undergraduates, postgraduates andprofessionals in science, engineering and medicine. It is alsoideal for students and professionals in statistics, economics,geography and the social sciences.
Doing Meta-Analysis with R: A Hands-On Guide serves as an accessible introduction on how meta-analyses can be conducted in R. Essential steps for meta-analysis are covered, including calculation and pooling of outcome measures, forest plots, heterogeneity diagnostics, subgroup analyses, meta-regression, methods to control for publication bias, risk of bias assessments and plotting tools. Advanced but highly relevant topics such as network meta-analysis, multi-three-level meta-analyses, Bayesian meta-analysis approaches and SEM meta-analysis are also covered. A companion R package, dmetar, is introduced at the beginning of the guide. It contains data sets and several helper functions for the meta and metafor package used in the guide. The programming and statistical background covered in the book are kept at a non-expert level, making the book widely accessible. Features • Contains two introductory chapters on how to set up an R environment and do basic imports/manipulations of meta-analysis data, including exercises • Describes statistical concepts clearly and concisely before applying them in R • Includes step-by-step guidance through the coding required to perform meta-analyses, and a companion R package for the book
An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance, marketing, and astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, deep learning, survival analysis, multiple testing, and more. Color graphics and real-world examples are used to illustrate the methods presented. This book is targeted at statisticians and non-statisticians alike, who wish to use cutting-edge statistical learning techniques to analyze their data. Four of the authors co-wrote An Introduction to Statistical Learning, With Applications in R (ISLR), which has become a mainstay of undergraduate and graduate classrooms worldwide, as well as an important reference book for data scientists. One of the keys to its success was that each chapter contains a tutorial on implementing the analyses and methods presented in the R scientific computing environment. However, in recent years Python has become a popular language for data science, and there has been increasing demand for a Python-based alternative to ISLR. Hence, this book (ISLP) covers the same materials as ISLR but with labs implemented in Python. These labs will be useful both for Python novices, as well as experienced users.
This book will be vital reading for anyone doing research, since using the web to find high quality information is a key research skill.

This volume provides an indispensable resource for anyone studying the Holocaust. The reference entries are enhanced by documents and other tools that make this volume a vital contribution to Holocaust research. This volume showcases a detailed look at the multifaceted attempts by Germany's Nazi regime, together with its collaborators, to annihilate the Jews of Europe during the Holocaust. Several introductory essays, along with a rich chronology, reference entries, primary documents, images, and a bibliography provide crucial information that readers will need in order to try to understand the Holocaust while undertaking research on that horrible event. This text looks not only at the history of the Holocaust, but also at examples of resistance (through armed violence, attempts at rescue, or the very act of survival itself); literary and cultural expressions that have attempted to deal with the Holocaust; the social and psychological implications of the Holocaust for today; and how historians and others have attempted to do justice to the memory of those killed and seek insight into why the Holocaust happened in the first place.
