The riveting story of the submarine force that helped win World War II by ravaging Japan's merchant fleet and destroying its economy. A dramatic account of extraordinary heroism, ingenuity, and perseverance--and the vital role American submarines played in winning the Pacific war.

The definitive account of the infamous 1967 attack on the USS Liberty by Israeli forces and the continuing controversy over what really happened. • Notorious incident: In 1967, Israeli fighter jets and torpedo boats attacked the spy ship uSS Liberty in international waters during the Six-Day War. Thirty-four sailors were killed and more than 170 wounded, many critically injured. Israel claimed mistaken identity, which a U.S. naval court of inquiry confirmed, but that explanation is contradicted by the facts of the case. • Based on new revelations: James Scott has interviewed Liberty survivors, senior u.S. political and intelligence officials, and examined newly declassified documents in Israel and the united States to write this comprehensive, dramatic account. He reveals that officers in Israel’s chain of command were aware of the Liberty’s identity and shows how events in Vietnam prompted the American government to deemphasize the attack despite widespread disbelief of Israel’s story. • Journalist and son of an attack survivor: Scott’s father, John, was an officer and engineer aboard the Liberty who was awarded the Silver Star for helping to save the ship from sinking.

Statistical Computation for Programmers, Scientists, Quants, Excel Users, and Other Professionals Using the open source R language, you can build powerful statistical models to answer many of your most challenging questions. R has traditionally been difficult for non-statisticians to learn, and most R books assume far too much knowledge to be of help. R for Everyone, Second Edition, is the solution. Drawing on his unsurpassed experience teaching new users, professional data scientist Jared P. Lander has written the perfect tutorial for anyone new to statistical programming and modeling. Organized to make learning easy and intuitive, this guide focuses on the 20 percent of R functionality you’ll need to accomplish 80 percent of modern data tasks. Lander’s self-contained chapters start with the absolute basics, offering extensive hands-on practice and sample code. You’ll download and install R; navigate and use the R environment; master basic program control, data import, manipulation, and visualization; and walk through several essential tests. Then, building on this foundation, you’ll construct several complete models, both linear and nonlinear, and use some data mining techniques. After all this you’ll make your code reproducible with LaTeX, RMarkdown, and Shiny. By the time you’re done, you won’t just know how to write R programs, you’ll be ready to tackle the statistical problems you care about most. Coverage includes Explore R, RStudio, and R packages Use R for math: variable types, vectors, calling functions, and more Exploit data structures, including data.frames, matrices, and lists Read many different types of data Create attractive, intuitive statistical graphics Write user-defined functions Control program flow with if, ifelse, and complex checks Improve program efficiency with group manipulations Combine and reshape multiple datasets Manipulate strings using R’s facilities and regular expressions Create normal, binomial, and Poisson probability distributions Build linear, generalized linear, and nonlinear models Program basic statistics: mean, standard deviation, and t-tests Train machine learning models Assess the quality of models and variable selection Prevent overfitting and perform variable selection, using the Elastic Net and Bayesian methods Analyze univariate and multivariate time series data Group data via K-means and hierarchical clustering Prepare reports, slideshows, and web pages with knitr Display interactive data with RMarkdown and htmlwidgets Implement dashboards with Shiny Build reusable R packages with devtools and Rcpp Register your product at informit.com/register for convenient access to downloads, updates, and corrections as they become available.

The Information Age: An Anthology on Its Impacts and Consequences was originally prepared by The Center for Advanced Concepts, Technologies, and Information Strategies of the Institute for National Strategic Studies, National Defense University. The original four volumes have been combined into one volume for this printing. They are: Part One: The Information and Communication Revolution Part Two: Business, Commerce, and Services Part Three: Government and the Military Part Four: International Affairs
