Book Description
La estadística está en todas partes: en las calificaciones de la escuela, en las encuestas que aspiran a anticipar un resultado electoral, en el descubrimiento de nuevas partículas elementales. Pero, ¿qué tiene de singular esta disciplina? Stephen M. Stigler propone que la sabiduría estadística se apoya en siete grandes pilares conceptuales que han ido madurando con el paso de los siglos y han contribuido a que hoy sea, por méritos propios, una ciencia versátil y rigurosa. Mediante el recuento de situaciones clave, la presentación de ideas que en su momento fueron revolucionarias y el retrato de algunos pensadores audaces, Stigler describe cómo al desechar parte de los datos en realidad podemos describirlos mejor, cómo aumenta la información cuando crece el número de observaciones, cómo se ha usado la probabilidad para cuantificar la precisión de una medida, cómo la variación interna de los datos puede ser suficiente para estudiarlos, cómo lo ya observado permite imaginar lo que aún no ocurre, cómo los procesos aleatorios pueden ser una magnífica herramienta y cómo se han desarrollado ciertos modelos teóricos para explicar todo tipo de fenómenos. El lector comprobará que esta sólida estructura explica por qué la estadística está aquí, allá y acullá.

Book Description
La desigualdad económica es uno de los fantasmas que hoy recorren el mundo. Lo mismo en países desarrollados que en los que se esfuerzan por salir de la miseria, este azote contemporáneo confirma de manera dolorosa que el progreso técnico, la apertura de los mercados y la diseminación de la democracia —sobre todo si se queda en su aspecto formal— son insuficientes para que los beneficios del crecimiento se distribuyan de modo equitativo. El World Inequality Lab, una iniciativa académica dirigida por los responsables de este volumen, ha construido en los últimos años la World Inequality Database, sin duda la más confiable fuente de información acerca de la desigualdad en el mundo; con este primer Informe sobre la desigualdad global se inicia la publicación bienal de estudios sobre cómo está evolucionando la distribución del ingreso y la riqueza. Convencidos de que la información de calidad es imprescindible para mejorar los debates sobre la necesaria acción del Estado y la sociedad organizada, los autores presentan aquí tendencias y análisis de la situación en el planeta y en países concretos hasta ahora poco estudiados, como China, Brasil o España, y concluyen con un sólido arsenal de políticas públicas para enfrentar este fenómeno cruel, injusto... y evitable. Tras examinar este informe [...] es fácil creer que la creciente concentración del ingreso es una imparable fuerza de la naturaleza, un efecto económico inevitable debido a la globalización y la tecnología. [...] Pero un análisis cuidadoso de los datos sugiere que la desbocada desigualdad no es algo fatal. Eduardo Porter y Karl Rusell, The New York Times Este libro se basa en una metodología pionera [...] Espero que los políticos puedan leerlo y dejen de contentarse con hacer uso de la palabra. De no hacerlo, una sociedad civil transnacional se apoderará de ella para convertirla en un arma de construcción masiva. Vittorio de Filippis, Libération

Book Description
This volume approaches the history of water in the Iberian Peninsula in a novel way, by linking it to the ongoing international debate on water crisis and solutions to overcome the lack of water in the Mediterranean. What water devices were found? What were the models for these devices? How were they distributed in the villas and monastic enclosures? What impact did hydraulic theoretical knowledge have on these water systems, and how could these systems impact on hydraulic technology? Guided by these questions, this book covers the history of water in the most significant cities, the role of water in landscape transformation, the irrigation systems and water devices in gardens and villas, and, lastly, the theoretical and educational background on water management and hydraulics in the Iberian Peninsula between the sixteenth and the nineteenth centuries. Historiography on water management in the territory that is today Spain has highlighted the region’s role as a mediator between the Islamic masters of water and the Christian world. The history of water in Portugal is less known, and it has been taken for granted that is similar to its neighbour. This book compares two countries that have the same historical roots and, therefore, many similar stories, but at the same time, offers insights into particular aspects of each country. It is recommended for scholars and researchers interested in any field of history of the early modern period and of the nineteenth century, as well as general readers interested in studies on the Iberian Peninsula, since it was the role model for many settlements in South America, Asia and Africa.

Book Description
What gives statistics its unity as a science? Stephen Stigler sets forth the seven foundational ideas of statistics—a scientific discipline related to but distinct from mathematics and computer science. Even the most basic idea—aggregation, exemplified by averaging—is counterintuitive. It allows one to gain information by discarding information, namely, the individuality of the observations. Stigler’s second pillar, information measurement, challenges the importance of “big data” by noting that observations are not all equally important: the amount of information in a data set is often proportional to only the square root of the number of observations, not the absolute number. The third idea is likelihood, the calibration of inferences with the use of probability. Intercomparison is the principle that statistical comparisons do not need to be made with respect to an external standard. The fifth pillar is regression, both a paradox (tall parents on average produce shorter children; tall children on average have shorter parents) and the basis of inference, including Bayesian inference and causal reasoning. The sixth concept captures the importance of experimental design—for example, by recognizing the gains to be had from a combinatorial approach with rigorous randomization. The seventh idea is the residual: the notion that a complicated phenomenon can be simplified by subtracting the effect of known causes, leaving a residual phenomenon that can be explained more easily. The Seven Pillars of Statistical Wisdom presents an original, unified account of statistical science that will fascinate the interested layperson and engage the professional statistician.

Book Description
This lively collection of essays examines statistical ideas with an ironic eye for their essence and what their history can tell us for current disputes. The topics range from 17th-century medicine and the circulation of blood, to the cause of the Great Depression, to the determinations of the shape of the Earth and the speed of light.

Book Description
Benito Pérez Galdós, considered Spain’s most important novelist after Cervantes, wrote 77 novels, several works of theater and a number of other tomes during his lifetime (1843–1920). His works have been translated into all major languages of the world, and many of his most highly regarded novels, those of the contemporary period, have been translated into English two, three and even four times over. Of the few “contemporary novels” of Galdós that until now have not come to light in English, The Forbidden is certainly among the most noteworthy. The story line concerns a wealthy philanderer, José María Bueno de Guzmán, who attempts to buy the favors of his three beautiful married cousins. He is successful with the first, Eloísa, a grasping materialist who falls deeply in love with him. Then he rejects her in order to attempt to seduce the youngest, Camila. Meanwhile, the third, the pseudo-intellectual María Juana, jealous, seduces José María. But it is Camila, healthy, impetuous and wild, who resists his temptations and holds our attention. The novelist and critic Leopoldo Alas, Galdós’s contemporary, calls her “the most feminine, graceful, lively female character that any modern novelist has painted.” As a naturalistic study, in the manner of Balzac in particular, principal characters of Galdós’s other novels (El doctor Centeno, La de Bringas, La familia de León Roch) become fleetingly visible in The Forbidden. In addition, the entire Bueno de Guzmán family gives evidence of the naturalistic emphasis on heredity: they all display certain physical or mental disorders. Eloísa has a morbid fear of feathers, María Juana often feels that she has a tiny piece of cloth caught in her teeth, José María suffers bouts of depression, an uncle is a kleptomaniac, one of the relatives writes letters to himself, etc. At the same time, this novel shows the foibles of Spanish society where status is determined by one’s associates, by the wearing of finery, and by living on borrowed money. In their history of Spanish literature, Chandler and Schwartz call Galdós “the greatest novelist of the nineteenth century and the only one who deserves to be mentioned in the same breath with great novelists like Balzac, Dickens and Dostoievsky.” The Forbidden, written at the height of the author’s creative powers, is a major work and its publication for an English-speaking audience is long overdue.
