The adult learner : the definitive classic in adult education and human resource development.

Es una lectura esencial para los profesionales del aprendizaje de adultos, estudiantes y profesionales de los recursos humanos, pues proporciona un marco teórico para la comprensión de los problemas del aprendizaje de adultos, tanto en los entornos docentes como en los lugares de trabajo. Se divide en tres partes: la primera parte estudia 'Las raíces de la andragogía', se traza el desarrollo de esta teoría y las características de los estudiantes adultos; en la segunda parte 'Los avances en el aprendizaje de adultos', se explican sus perspectivas de futuro en la investigación y la práctica y, en la última parte, 'Practica en el aprendizaje de adultos', se presentan lecturas seleccionadas que desarrollan los aspectos específicos de la andragogía en la práctica y que incluye estrategias para implementar los supuestos básicos, para adaptar el aprendizaje a las diferencias individuales, y para implementar la educación de adultos en las organizaciones. De especial interés son dos instrumentos de autoevaluación, 'the Core Competency Diagnostic and Planning Guide' y 'the Personal Adult Learning Style Inventory' que permiten al lector ponerse en camino del desarrollo personal en el aprendizaje de adultos.

A framework for revitalisation of rural education and training systems in sub-Saharan Africa: Strengthening the human resource base for food security and sustainable livelihoods

Recent studies of the current state of rural education and training (RET) systems in sub-Saharan Africa have assessed their ability to provide for the learning needs essential for more knowledgeable and productive small-scale rural households. These are most necessary if the endemic causes of rural poverty (poor nutrition, lack of sustainable livelihoods, etc.) are to be overcome. A brief historical background and analysis of the major current constraints to improvement in the sector are discussed. Paramount among those factors leading to its present 'malaise' is the lack of a whole-systems perspective and the absence of any coherent policy framework in most countries. There is evidence of some recent innovations, both in the public sector and through the work of non-governmental organisations (NGOs), civil society organisations (CSOs) and other private bodies. These provide hope of a new sense of direction that could lead towards meaningful 'revitalisation' of the sector. A suggested framework offers 10 key steps which, it is argued, could largely be achieved with modest internal resources and very little external support, provided that the necessary leadership and managerial capacities are in place.

Maximizing revenue in Grid markets using an economically enhanced resource manager

Traditional resource management has had as its main objective the optimization of throughput, based on parameters such as CPU, memory, and network bandwidth. With the appearance of Grid markets, new variables that determine economic expenditure, benefit and opportunity must be taken into account. The Self-organizing ICT Resource Management (SORMA) project aims at allowing resource owners and consumers to exploit market mechanisms to sell and buy resources across the Grid. SORMA's motivation is to achieve efficient resource utilization by maximizing revenue for resource providers and minimizing the cost of resource consumption within a market environment. An overriding factor in Grid markets is the need to ensure that the desired quality of service levels meet the expectations of market participants. This paper explains the proposed use of an economically enhanced resource manager (EERM) for resource provisioning based on economic models. In particular, this paper describes techniques used by the EERM to support revenue maximization across multiple service level agreements and provides an application scenario to demonstrate its usefulness and effectiveness.
