Arsenic contamination has become a global phenomenon. With the development of advanced technological detection tools, more geographical areas have been identified. The people most affected are those in the poorer socio-economic groups. The research articles in this book have been contributed by scientists working in areas severely affected by these difficulties. The book includes an assessment of environmental health risks and economic impacts, and the technologies available for dealing with the problem. Written in a straightforward style, the book is designed to update knowledge on the dynamics of natural arsenic from the aquifers through groundwater to the food chain. It outlines efficient techniques for arsenic removal and inform administrators, policy makers and company executives, and aims to increase awareness of the problem.

El presente libro denominado MANUAL PARA LA ELABORACIÓN E IMPLEMENTACION DE UN MODELO DE EVALUACIÓN POR COMPETENCIAS, es el resultado de once años de trabajo, asesoría y acompañamiento a tres grandes instituciones públicas, en donde he sido Rector y de las cuales me siento muy orgulloso. Este manual parte primero desde lo que es la fundamentación, es decir el manejo de conceptos claves como: competencias, evaluación enseñar y aprender desde la perspectiva de procesos. De modo que el lector tenga una clara concepción de lo que debe saber sobre el tema y así poder plantear un modelo y los pasos que se deben seguir para su implementación. Este manual le permite a los docentes crear un modelo práctico de evaluación que facilita la promoción y el éxito de los estudiantes. En la mayoría de países latinoamericanos se habla mucho de competencias, pero no se tiene bien claro que son y cómo aplicarlas en el contexto de la escuela y más complicado aún el cómo volverlas un elemento base para el proceso de evaluación. Este manual pretende ofrecer un enfoque o concepción básica de competencia en donde el docente en un lenguaje sencillo pueda entenderla en toda su esencia y aplicación. Otro aspecto importante de este manual está en ofrecer procedimientos que faciliten el proceso de evaluación en las instituciones educativas, acompañado de una serie de instrumentos que le permitan a las instituciones contar con herramientas que evidencien los avances de la evaluación en las instituciones, herramientas que le darán mayor forma al diseño curricular.

The Latin American and Caribbean countries have seen growing pressure on water resources, with increasing demand and costs, for agricultural, domestic and industrial consumption. This has brought about the need to maximize and augment the use of existing or unexploited sources of freshwater. There are many modern and traditional alternative technologies for improving the utility and augmenting the supply of water being employed in various countries, but with limited application elsewhere due to the lack of information transfer among water resources managers and planners. This source book provides water resource managers and planners, especially in developing countries and in countries with economies in transition, with information on the range of technologies that have been developed and used in the various countries throughout the world.
