El conocimiento estadístico se ha de basar en la realidad, en lo que es observable, para poder elaborar conclusiones acerca de los fenómenos aleatorios. La teoría que desarrolla los procesos de evaluacion de las conclusiones y que facilita el metodo de validacion de las mismas es la inferencia estadistica. Esta teoria acoge necesariamente el calculo de probabilidades, tanto para disponer de modelos que permitan explicar los fenomenos analizados como para medir la aleatoriedad de la informacion utilizada y de las propias conclusiones alcanzadas. El modelo de sistematizacion, analisis y sintesis de la informacion disponible es la estadistica descriptiva.Esta obra recoge, de manera sistematizada y pedagogica, una seleccion de problemas que ayudan al estudiante a comprender y asimilar los conceptos relativos a la estadistica descriptiva y al calculo de probabilidades para poder aplicarlos posteriormente en los procesos de inferencia. El objetivo es facilitar al alumno la comprension de aquellos conocimientos estadisticos a los cuales se enfrenta por primera vez en los primeros cursos de su ingenieria, licenciatura o diplomatura. Para ello, los ejercicios estan resueltos de forma clara, rigurosa y completa, ofreciendo los distintos enfoques que el problema o ejercicio pueda presentar.

An exquisitely illustrated, one-of-a-kind celebration of the hidden beauty of nature and the ingenuity of birdsSusan Ogilvy started painting bird nests almost by accident. One day, while tidying up her garden after a storm, she found a chaffinch nest - a strange, sodden lump on the grass under a fir tree. She carried it inside and placed it on a newspaper; over the next few hours, as the water drained out of it, the sodden lump blossomed into a mossy jewel. She was amazed, and dropped everything to make a painting of the nest at exact life size.This was the start of an obsession; Ogilvy has since painted more than fifty bird nests from life, each time marvelling at its ingenious construction. Every species of bird has its own vernacular, but sources its materials - most commonly twigs, roots, grasses, reeds, leaves, moss, lichen, hair, feathers and cobwebs, less usually, mattress stuffing and string - according to local availability. Ogilvy would, of course, never disturb nesting birds; instead she relies upon serendipity, which is why all her nests have either been abandoned after fulfilling their purpose, or displaced by strong winds.Although Nests showcases the specimens she has found near her homes in Somerset and on the Isle of Arran, its subject matter is by no means only British, since these same birds can be found all over Europe, Scandinavia and as far afield as Russia, Turkey and North Africa. This wondrous book is all the more special for its rarity. Few modern books exist specifically on the subject of bird nests; the most recent among the author's reference works was published in 1932. Exquisitely designed and packaged, Nests will be an essential addition to the libraries of all nature lovers.

Un cativo correndo tralas pombas. Un vello, tódolos días á mesma hora, botándolles faragullas de pan ós pardais. Unha nai, fermosa e aburrida, sentada nun banco do xardín, sentindo o canto do merlo que trae a primavera. O naturalista que descobre un falcón pequeno acelerando tras dos anduróns. Un rapaz que se pregunta cal é ese paxariño pardo, rechoncho e de cola curta e ergueita que se move polas sebes. E tamén as gaivotas dos basureiros urbanos, que comparten espacio cos gabiáns, os corvos, as pegas ou mesmo as aves dos estanques. ¿Quen son e de onde saen todas estas aves? Veciñas do home. Aves Urbanas de Galicia ofrécelle ó lector unha perspectiva distinta: a de todas esas aves que tamén se moven nese terreo inhóspito, ermo, de rúas e casas, de tráfico e barullo, no que os parques e xardíns funcionan coma un oasis apetecible. Paxaros que se adaptaron a ese medio, e do que algunhas especies aprenderon, mesmo, a sacar innegables vantaxes. Desde os pardais ás pombas, desde as rulas ós corvos, desde as gaivotas ó pimpín, desde o merlo á cegoña, desde a coruxa ós estorniños, desde os peneireiros ó carrizo, desde a pega ó moucho, desde as andoriñas ó gabián. Xa sabemos que existen; agora coñeceremos as súas formas, cores e costumes.

BRAILOVSKY ANTONIO ELIOEn este libro se desarrolla una investigación a fondo de la ecología en el seno de la historia de la Argentina. Desde la agricultura incaica hasta la energía nuclear, los argentinos dan cuenta del paisaje que habitan y su equilibrio ambiental. Surge asi, del testimonio de cronistas, investigadores, cientificos, un pais desconocido. Sus recursos naturales, sus tristezas, miserias y exitos y, sobre todo, sus consecuencias sobre la calidad de vida de las personas. En este recorrido se cruza una reflexion sobre la ecologia y la historia que permite comprender ambas de una manera diferente. Memoria verde no es solo una investigacion sobre lejanos hechos de nuestro pasado: es una herramienta de accion. Su influencia directa sobre los lectores que sienten el peligro de la destruccion de nuestro medio natural ya lo convirtio, sin duda, en un documento de consulta indispensable.
