Available in PDF, EPUB and Kindle. Book excerpt: Este libro ha sido desarrollado como una guía sencilla para la elaboración de prácticas de suelo, tanto en campo como en laboratorio, usando métodos simples con los que se puede prescindir de espacios especializados para estos análisis. El autor no pretende impartir cátedra sobre el estricto quehacer del estudio del suelo, el cual es imposible abarcar en una obra pequeña como esta, sino contribuir mediante prácticas sencillas, al conocimiento y comprensión de algunas de sus características, que tienen relación con los aspectos ambientales y las dinámicas ecosistémicas que se abordan desde la óptica de las ciencias ambientales, la agronomía o la ingeniería, entre otras. El autor ha incluido un gran número de imágenes que pretenden recrear, además del desarrollo de las prácticas, algunos de los tipos de minerales más comunes que se pueden encontrar en el suelo. Estas fotografías, muchas a color, ponen en la mano del lector características como el color, la textura y, en términos generales, la apariencia que poseen las rocas, las cuales aparecen habitualmente contenidas en voluminosos atlas de mineralogía o textos especializados en geología, de difícil acceso por su elevado costo. Por el contrario, el tamaño de este libro lo hace cómodo e ilustrativo para llevarlo a campo y al laboratorio.

This book was released on 2020-08-13 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: El país está enfrentado un tema tan crítico como la apertura económica -tratados recién firmados como el TLC con Estados Unidos- obligan a los gremios del sector productivo a ser más competitivos si quieren continuar en el mercado. Uno de los elementos para mejorar este aspecto es la eficiencia en el uso de los recursos (fertilizantes, riegos, manejo sostenible del medio ambiente, etc.). La toma de decisiones es un paso difícil en cualquier empresa. En la empresa agropecuaria intervienen muchos elementos, componentes y variables que es necesario conocer a la hora de decidir. Como el momento de las decisiones y los resultados están alejados en el tiempo, los problemas se manifiestan cuando suele ser tarde para resolverlos. Así, para tomar buenas decisiones es fundamental una correcta información previa. Un análisis equivocado lleva siempre a un mal resultado; cuando los márgenes de ganancia de la actividad agropecuaria se reducen, el costo del error puede ser crítico. Las buenas decisiones solo pueden ser resultado de un correcto análisis de las variables y esto solo puede hacerse con buena información.

Download or read book Glosario Del Banco Mundial written by World Bank and published by World Bank Publications. This book was released on 1996 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Download or read book Qualitative Choice Analysis written by Kenneth Train and published by MIT Press. This book was released on 1986 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses two significant research areas in an interdependent fashion. It is first of all a comprehensive but concise text that covers the recently developed and widely applicable methods of qualitative choice analysis, illustrating the general theory through simulation models of automobile demand and use. It is also a detailed study of automobile demand and use, presenting forecasts based on these powerful new techniques. The book develops the general principles that underlie qualitative choice models that are now being applied in numerous fields in addition to transportation, such as housing, labor, energy, communications, and criminology. The general form, derivation, and estimation of qualitative choice models are explained, and the major models - logit, probit, and GEV - are discussed in detail. And continuous/discrete models are introduced. In these, qualitative choice methods and standard regression techniques are combined to analyze situations that neither alone can accurately forecast. Summarizing previous research on auto demand, the book shows how qualitative choice methods can be used by applying them to specific auto-related decisions as the aggregate of individuals' choices. The simulation model that is constructed is a significant improvement over older models, and should prove more useful to agencies and organizations requiring accurate forecasting of auto demand and use for planning and policy development. The book concludes with an actual case study based on a model designed for the investigations of the California Energy Commission. Kenneth Train is Visiting Associate Professor in Economics at the University of California, Berkeley, and Director of Economic Research at Cambridge Systematics, Inc., also in Berkeley. Qualitative Choice Analysisis included in The MIT Press Transportation Studies Series, edited by Marvin L. Manheim.
