Book Description
Este libro brinda herramientas matemáticas utilizadas para modelar y analizar la evolución de sistemas que varían en el tiempo. Trata en profundidad la teoría de ecuaciones de diferencias y diferenciales, tanto para una como para múltiples variables. La teoría se presenta a través de numerosos ejemplos y problemas propuestos, principalmente del área económica, que persiguen desarrollar la capacidad matemática y de modelamiento del lector. Especial énfasis se ha puesto en el planteamiento de problemas económicos y en el análisis de las soluciones, sin descuidar sus métodos.

Book Description
En los sistemas complejos, cada problema, debe ser tratado en detalle partiendo de cero, y poco o nada de lo aprendido al resolver un sistema anterior nos puede ayudar a entender uno nuevo. En los sistemas caóticos, de dos condiciones iniciales ligeramente distintas se obtienen, en el tiempo, dos soluciones dramáticamente diferentes. Casi todos los sistemas reales son termodinámicamente abiertos, mientras que los sistemas aislados, fuera de ser considerados sólo teóricamente, son raros en la naturaleza. La naturaleza sigue el principio del orden a partir del caos o desorden, contrario diametralmente al que estipula la física clásica, que va del orden al desorden, La visión del mundo de los sistemas complejos exige una nueva forma de hacer ciencia. La complejidad, un travestista del enfoque ético sistémico, intenta dar solución a problemas considerados como críticos, y crítico es todo lo que desconocemos, y para acceder a lo desconocido, según las reglas actuales, se reclama un episentido.

Book Description
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.

Book Description
Contrary to conventional wisdom that equates rural economies with agriculture, rural residents in developing countries often rely heavily on activities other than farming for their income. Indeed, nonfarm work accounts for between one-third and one-half of rural incomes in the developing world. In recent years, accelerating globalization, increasing competition from large businesses, expanding urban markets for rural goods and services, and greater availability of information and communication technology have combined to expose rural nonfarm businesses to new opportunities as well as new risks. By examining these rapid changes in the rural nonfarm economy, international experts explore how the rural nonfarm economy can contribute to overall economic growth in developing countries and how the poor can participate in this rapidly evolving segment of the economy. The authors review an array of recent studies of the rural nonfarm economy in order to summarize existing empirical evidence, explore policy implications, and identify future research priorities. They examine the varied scale, structure, and composition of the rural nonfarm economy, as well as its relationship with agricultural and urban enterprises. And they address key questions about the role of public intervention in the rural nonfarm economy and how the rural poor can participate in and navigate the rapid transition underway in rural areas. The contributors offer new insights to specialists in rural development and to others interested in overall economic development.

Book Description
From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.

Book Description
It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability.
