¿Cómo ejecutar una estrategia efectiva en medio de la operación día a día? Diez años de experiencia al precio de un libro. Bestseller de The New York Times. ¿Recuerda la última gran iniciativa que vio languidecer en su empresa? ¿Se desplomó estrepitosamente? ¿Cedió ante la sofocante presión de otras prioridades? Da igual: para cuando se esfumó del todo, ni quien se acordara. ¿Qué fue lo que pasó? La vorágine de la urgencia cotidiana acabó devorando el tiempo y la energía que requiere invertir en la ejecución de su estrategia para el día de mañana. Este método le dará una vuelta de tuerca a esta realidad para siempre. Las 4 Disciplinas de la Ejecución (4DX) es una fórmula simple, repetible y probada para ejecutar sus prioridades estratégicas más importantes en medio del torbellino cotidiano. ¿Cómo? Siguiendo al pie de la letra las 4 disciplinas: o Enfocarse en lo crucialmente importante o Actuar sobre las medidas de predicción o Llevar un tablero de resultados o Crear una cadencia de rendición de cuentas Al seguir estas disciplinas, los líderes pueden generar resultados contundentes, incluso cuando la estrategia requiere un cambio de actitud significativo por parte de los miembros de su equipo. 4DX no es teoría. Se trata un conjunto de prácticas probadas y refinadas por cientos de organizaciones y miles de equipos de trabajo a lo largo de los años. Cuando una empresa o un individuo se adhiere a estas disciplinas, logra resultados sorprendentes. 4DX representa una nueva forma de pensar que resulta esencial para destacar en un mundo tan competitivo como este en que nos tocó vivir. En pocas palabras: éste es un libro que ningún líder de negocios se puede perder.

Los versos satánicos es la novela más célebre, iconoclasta y polémica de Salman Rushdie. Una referencia ineludible de la literatura de nuestro tiempo. Un avión secuestrado estalla a gran altura sobre el canal de la Mancha. Dos supervivientes caen al mar: Gibrel Farishta, un legendario galán cinematográfico, y Saladin Chamcha, el hombre de las mil voces, autodidacta y anglófilo furibundo. Consiguen llegar a una playa inglesa y notan unos extraños cambios: uno ha adquirido una aureola y el otro ve con horror cómo crece el vello de sus piernas, los pies se le convierten en cascos y las sienes se abultan... Reseña: «Una obra prodigiosa, brillante, deleitable.» Nadine Gordimer

Classical Electromagnetism in a Nutshell

This graduate-level physics textbook provides a comprehensive treatment of the basic principles and phenomena of classical electromagnetism. While many electromagnetism texts use the subject to teach mathematical methods of physics, here the emphasis is on the physical ideas themselves. Anupam Garg distinguishes between electromagnetism in vacuum and that in material media, stressing that the core physical questions are different for each. In vacuum, the focus is on the fundamental content of electromagnetic laws, symmetries, conservation laws, and the implications for phenomena such as radiation and light. In material media, the focus is on understanding the response of the media to imposed fields, the attendant constitutive relations, and the phenomena encountered in different types of media such as dielectrics, ferromagnets, and conductors. The text includes applications to many topical subjects, such as magnetic levitation, plasmas, laser beams, and synchrotrons. Classical Electromagnetism in a Nutshell is ideal for a yearlong graduate course and features more than 300 problems, with solutions to many of the advanced ones. Key formulas are given in both SI and Gaussian units; the book includes a discussion of how to convert between them, making it accessible to adherents of both systems. Offers a complete treatment of classical electromagnetism Emphasizes physical ideas Separates the treatment of electromagnetism in vacuum and material media Presents key formulas in both SI and Gaussian units Covers applications to other areas of physics Includes more than 300 problems

Nuclear Physics in a Nutshell provides a clear, concise, and up-to-date overview of the atomic nucleus and the theories that seek to explain it. Bringing together a systematic explanation of hadrons, nuclei, and stars for the first time in one volume, Carlos A. Bertulani provides the core material needed by graduate and advanced undergraduate students of physics to acquire a solid understanding of nuclear and particle science. Nuclear Physics in a Nutshell is the definitive new resource for anyone considering a career in this dynamic field. The book opens by setting nuclear physics in the context of elementary particle physics and then shows how simple models can provide an understanding of the properties of nuclei, both in their ground states and excited states, and also of the nature of nuclear reactions. It then describes: nuclear constituents and their characteristics; nuclear interactions; nuclear structure, including the liquid-drop model approach, and the nuclear shell model; and recent developments such as the nuclear mean-field and the nuclear physics of very light nuclei, nuclear reactions with unstable nuclear beams, and the role of nuclear physics in energy production and nucleosynthesis in stars. Throughout, discussions of theory are reinforced with examples that provide applications, thus aiding students in their reading and analysis of current literature. Each chapter closes with problems, and appendixes address supporting technical topics.

R is the most widely used open-source statistical and programming environment for the analysis and visualization of biological data. Drawing on Gregg Hartvigsen's extensive experience teaching biostatistics and modeling biological systems, this text is an engaging, practical, and lab-oriented introduction to R for students in the life sciences. Underscoring the importance of R and RStudio in organizing, computing, and visualizing biological statistics and data, Hartvigsen guides readers through the processes of entering data into R, working with data in R, and using R to visualize data using histograms, boxplots, barplots, scatterplots, and other common graph types. He covers testing data for normality, defining and identifying outliers, and working with non-normal data. Students are introduced to common one- and two-sample tests as well as one- and two-way analysis of variance (ANOVA), correlation, and linear and nonlinear regression analyses. This volume also includes a section on advanced procedures and a chapter introducing algorithms and the art of programming using R.
