Available in PDF, EPUB and Kindle. Book excerpt: The relationship between the presidency and the press has transformed—seemingly overnight—from one where reports and columns were filed, edited, and deliberated for hours before publication into a brave new world where texts, tweets, and sound bites race from composition to release within a matter of seconds. This change, which has ultimately made political journalism both more open and more difficult, brings about many questions, but perhaps the two most important are these: Are the hard questions still being asked? Are they still being answered? In Columns to Characters, Stephanie A. Martin and top scholars and journalists offer a fresh perspective on how the evolution of technology affects the way presidents interact with the public. From Bill Clinton’s saxophone playing on the Arsenio Hall Show to Barack Obama’s skillful use of YouTube, Twitter, and Reddit as the first “social media president,” political communication appears to reflect the increasing fragmentation of the American public. The accessible essays here explore these implications in a variety of real-world circumstances: the “narcotizing” numbness of information overload and voter apathy; the concerns over privacy, security, and civil liberties; new methods of running political campaigns and mobilizing support for programs; and a future “post-rhetorical presidency” in which the press is all but irrelevant. Each section of the book concludes with a “reality check,” a short reflection by a working journalist (or, in one case, a former White House insider) on the presidential beat.

Download or read book A Data Scientist s Guide to Acquiring Cleaning and Managing Data in R written by Samuel E. Buttrey and published by John Wiley & Sons. This book was released on 2017-12-18 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only how-to guide offering a unified, systemic approach to acquiring, cleaning, and managing data in R Every experienced practitioner knows that preparing data for modeling is a painstaking, time-consuming process. Adding to the difficulty is that most modelers learn the steps involved in cleaning and managing data piecemeal, often on the fly, or they develop their own ad hoc methods. This book helps simplify their task by providing a unified, systematic approach to acquiring, modeling, manipulating, cleaning, and maintaining data in R. Starting with the very basics, data scientists Samuel E. Buttrey and Lyn R. Whitaker walk readers through the entire process. From what data looks like and what it should look like, they progress through all the steps involved in getting data ready for modeling. They describe best practices for acquiring data from numerous sources; explore key issues in data handling, including text/regular expressions, big data, parallel processing, merging, matching, and checking for duplicates; and outline highly efficient and reliable techniques for documenting data and recordkeeping, including audit trails, getting data back out of R, and more. The only single-source guide to R data and its preparation, it describes best practices for acquiring, manipulating, cleaning, and maintaining data Begins with the basics and walks readers through all the steps necessary to get data ready for the modeling process Provides expert guidance on how to document the processes described so that they are reproducible Written by seasoned professionals, it provides both introductory and advanced techniques Features case studies with supporting data and R code, hosted on a companion website A Data Scientist's Guide to Acquiring, Cleaning and Managing Data in R is a valuable working resource/bench manual for practitioners who collect and analyze data, lab scientists and research associates of all levels of experience, and graduate-level data mining students.

Available in PDF, EPUB and Kindle. Book excerpt: Bioinformatics - Trends and Methodologies is a collection of different views on most recent topics and basic concepts in bioinformatics. This book suits young researchers who seek basic fundamentals of bioinformatic skills such as data mining, data integration, sequence analysis and gene expression analysis as well as scientists who are interested in current research in computational biology and bioinformatics including next generation sequencing, transcriptional analysis and drug design. Because of the rapid development of new technologies in molecular biology, new bioinformatic techniques emerge accordingly to keep the pace of in silico development of life science. This book focuses partly on such new techniques and their applications in biomedical science. These techniques maybe useful in identification of some diseases and cellular disorders and narrow down the number of experiments required for medical diagnostic.
Download or read book Topology of Numbers written by Allen Hatcher and published by American Mathematical Society. This book was released on 2022-10-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as an introduction to number theory at the undergraduate level, emphasizing geometric aspects of the subject. The geometric approach is exploited to explore in some depth the classical topic of quadratic forms with integer coefficients, a central topic of the book. Quadratic forms of this type in two variables have a very rich theory, developed mostly by Euler, Lagrange, Legendre, and Gauss during the period 1750–1800. In this book their approach is modernized by using the splendid visualization tool introduced by John Conway in the 1990s called the topograph of a quadratic form. Besides the intrinsic interest of quadratic forms, this theory has also served as a stepping stone for many later developments in algebra and number theory. The book is accessible to students with a basic knowledge of linear algebra and arithmetic modulo $n$. Some exposure to mathematical proofs will also be helpful. The early chapters focus on examples rather than general theorems, but theorems and their proofs play a larger role as the book progresses.

Book excerpt: A Primer for Computational Biology aims to provide life scientists and students the skills necessary for research in a data-rich world. The text covers accessing and using remote servers via the command-line, writing programs and pipelines for data analysis, and provides useful vocabulary for interdisciplinary work. The book is broken into three parts: Introduction to Unix/Linux: The command-line is the "natural environment" of scientific computing, and this part covers a wide range of topics, including logging in, working with files and directories, installing programs and writing scripts, and the powerful "pipe" operator for file and data manipulation. Programming in Python: Python is both a premier language for learning and a common choice in scientific software development. This part covers the basic concepts in programming (data types, if-statements and loops, functions) via examples of DNA-sequence analysis. This part also covers more complex subjects in software development such as objects and classes, modules, and APIs. Programming in R: The R language specializes in statistical data analysis, and is also quite useful for visualizing large datasets. This third part covers the basics of R as a programming language (data types, if-statements, functions, loops and when to use them) as well as techniques for large-scale, multi-test analyses. Other topics include S3 classes and data visualization with ggplot2.

Download or read book Sixth Column written by Robert A. Heinlein and published by Baen Publishing Enterprises. This book was released on 2012-01-01 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the U.S. is conquered, an enclave of brilliant misfits leads a rebellion against near-impossible odds. The totalitarian East has triumphed in a massive invasion and the United States has fallen to a dictatorial superpower bent on total domination. That power is consolidating its grip via concentration camps, police state tactics, and a total monopoly upon the very thoughts of the conquered populace. A tiny enclave of scientists and soldiers survives, unbeknownst to America's new rulers. It's six against six million¾but those six happen to include a scientific genius, a master of subterfuge and disguise who learned his trade as a lawyer-turned-hobo, and a tough-minded commander who knows how to get the best out of his rag-tag assortment of American discontents, wily operators, and geniuses. It's going to take technological savvy and a propaganda campaign that would leave Madison Avenue aghast, but the U.S. will rise again. The counterinsurgency for freedom is on, and defeat is not an option. At the publisher's request, this title is sold without DRM (Digital Rights Management).
