The importance of protecting the environment against pollution is an objective which gained international acceptance in the recent years. According to the first principle of the Declaration of the United Nations Conference on the Human Environment which took place in Stockholm in 1972, "man .... bears a solemn responsibility to protect and improve the environment for present and future genera­ tions". The United Nations again in their desire t...

In April 1979 a symposium on "Multiple Somatic Sensory Motor, Visual and Auditory Areas and Their Connectivities" was held at the FASEB meeting in Dallas, Texas under the auspices of the Committee on the Nervous System of the American Physiological Society. The papers presented at that symposium are the basis of most of the substantially augmented, updated chapters in the three volumes of Cortical Sensory Organization. Only material in chap­ t...

At a fairly early stage of socialism's penetration into the Afro-Asian world, a handful of European social democrats established an Indian Social-Democratic Association (lSDV). They did so in a country, Indonesia, that was economically little developed and far away from any of the centres of European socialism and Asiatic radical-national­ ism. The ISDV was soon able to bring its influence to bear on sec­ tions of the urban proletariat and to ...

This is the latest effort in a sequence of presentations begun in 1949 with a series of lectures on long-focus photographic astrometry given by the author as Fulbright professor in Paris at the invitation by the late H. Mineur, at that time Director of the Institut d' Astrophysique. These earlier lectures were published as a series of review articles in Popular Astronomy (1951) and appeared both as Contributions de l'Institut d'Astrophysique, ...

Proceedings of a conference of experts on cocaine addiction, this early volume documents the devastating effects of crack, then a new cocaine preparation, and its extraordinary addicting properties. The Bahamian experience with crack provided an early warning about the extreme personal and social dangers of this drug .

Soviet Russia will conquer all the millions of problems that stand in its way, on one condition: as long as the cause of the political education of the broad masses of the people continually advances. We have nothing to be afraid of, if our people fully learns to distinguish who are its friends and who are its enemies. The trial of the Socialist Revolutionaries must and shall be a great step forward in the cause of the political instruction of...

The Third International Symposium on Paleolimnology was held at the beginning of September 1981 in Finland. After registration at the University of 10ensuu and the opening session and welcome reception in the Town Hall, the participants moved to a hotel at Koli, a hill famed as a landmark and for its panoramic view. Here the lecture session, lasting four days, took place. Momentarily, the mosaic of the lakeland became visible between the cloud...

This special issue of Space Science Reviews contains selected papers on electromagnetic man-made and natural environmental interactions. Originally these papers were pre­ sented at the Fifth International Wrocfaw Symposium on Electromagnetic Compatibility. Wroclaw (Poland), 17-19 September, 1980, a biennial gathering of scientists and engineers. At that time, the symposium organizers selected a few persons of recognized authority and invited t...

Only in fairly recent years has History and Philosophy of Science been recognized - though not always under that name - as a distinct field of scholarly endeavour. Previously, in the Australasian region as elsewhere, those few individuals working within this broad area of inquiry found their base, both intellectually and socially, where they could. In fact, the institutionalization of History and Philosophy of Science began compara­ tively ear...

The present work addresses itself to the question of the nature of appraisive concepts such as were the subject of investigation in The Concepts of Value* and The Concepts of Criticism. ** Many problems of prime importance in the theory of value could not be adequately treated there without diminishing the basic purpose of those studies which was above all to identify, classify and provide a general theoretical framework for the host of concep...

The book is divided into chapters, but several themes run across them. This is, in fact, the reason for writing a book rather than a number of independent articles, for it appears that several moments of Kant's work are characterized by similar problems, and consequently we might be unable to see the impact of these on a more 1 i mi ted canvas. But further, and perhaps no less importantly, the shared problems are likely to be indicative of the...

Saber cuáles son las estrategias más adecuadas en la crianza infantil, conocer cuáles son las pautas que deben manejarse dentro del hogar para establecer la armonía, decidir si estos modelos educativos son aplicables en un contexto escolar, son algunas de las interrogantes que se abordan en las investigaciones en Psicología Educativa y del Desarrollo. Los estilos de crianza y las interacciones familiares son herramientas que se ponen en prácti...

En la actualidad, las redes de sensores inalámbricos (WSN) gozan de un gran interés tanto en la comunidad científica como en elmundo empresarial. Los sensores que componene las WSNs tienen muchas limitaciones físicas lo que hace que los protocolos de encaminamiento desarrollados para WSNs deban ser simples en términos de computabilidad y eficientes en cuanto a consumo energético. En este trabajo abordadomos el diseño y evaluación de algoritmos...

Con la caída del comunismo, se aceleraron los procesos de integración regionales para competir en un mundo marcado por la libre circulación de bienes y mercancias. En el camino, algunos bloques han optado por incluir a los movimientos migratorios como parte de su estrategia de desarrollo y de integración, empero, algunos otros han optado por restringir o descartar a los migrantes en sus agendas multilaterales. El trabajo que se desarrolla en e...

Tesis para optar al grado de Magister en Educación con mención en Currículo y Comunidad Educativa realizada en colegios municiapales de una comuna de la región Metropolitana en Santiago de Chile. La función de la educación, de la escuela y del profesor no tiene sentido si no es en la interacción social, por lo tanto los problemas que se perciben en el desarrollo del quehacer del docente no pueden analizarse fuera del contexto en que ésta se re...

Este libro es una composición atrevida de tres temas, uno para cada capítulo: lógica, simulación y aprendizaje automático. La idea que conecta los tres temas es la noción de agente. En el capítulo 1 se revisa una forma de lógica, la Lógica Computacional, y se le usa como lenguaje de alto nivel para modelar un conjunto de agentes y sus formas de razonamiento. En el capítulo 2, el foco del libro gira hacia el modelado de los ambientes en los que...

En el presente trabajo se describen los procesos experimentales y se plantean varios modelos teóricos que permiten determinar el comportamiento electromagnético, térmico, óptico y en frecuencia de materiales cerámicos amorfos, en condiciones de laboratorio utilizados en el proceso de fabricación fundamentalmente, de piso cerámico. Uno de los aspectos relevantes de los resultados presentados en este informe, es la posibilidad de usar esta clase...

El caso Agreal es sumamente difícil de juzgar por la complejidad del problema y por los múltiples medios y estrategias que va a utilizar la industria demandada en su defensa. Agreal no solo fue un medicamento con información defectuosa sino que esta inducía a error. El Ministerio de Sanidad ordenó su retirada en 2005. Cuando las mujeres afectadas solicitaron el estudio de sus casos, se creó una Comisión de expertos que, sin reconocerlas jamás,...

La costa norte de Puerto Rico está influenciada por las constantes tormentas y frentes fríos del Atlántico Norte. La plataforma insular, en esta zona, es angosta comparada con la del resto de la Isla, por lo que la energía que transportan las olas no sufre disipación significativa, por efectos de fricción de fondo, al acercarse a la línea de costa. En este trabajo de hace un análisis de las características del oleaje en la costa norte de Puert...
