Measurement of highly transient electrical charging following high-intensity laser-solid interaction

The multi-million-electron-volt proton beams accelerated during high-intensity laser-solid interactions have been used as a particle probe to investigate the electric charging of microscopic targets laser-irradiated at intensity similar to10(19) W cm(2). The charge-up, detected via the proton deflection with high temporal and spatial resolution, is due to the escape of energetic electrons generated during the interaction. The analysis of the data is supported by three- dimensional tracing of the proton trajectories. (C) 2003 American Institute of Physics.

the social economy as an alternative of self employment. profile of the entrepreneur in the andalusian labour companies

This paper provides a quantitative and qualitative analysis of the profile of the entrepreneur who decides to start business through a labor society in the context of the Autonomous Community of Andalucia. Thus, first the Social Economy is presented as an important alternative to creating and promoting employment, which seeks to combine economic and social objectives in the development of activities. Subsequently, focusing on labor companies, updated its importance in the regional economy for later data and through the analysis of two samples are available, set the attributes or most significant characteristics of these entrepreneurs.

Concepto pedagógico de "formación" en la empresa actual

Las organizaciones empresariales han cambiado desde inicios del siglo XX hasta la actualidad. Este cambio es continuo y los nuevos escenarios invitan a una participación más activa de la pedagogía en el entorno empresarial. Ahora no es suficiente con competir para obtener un mayor beneficio, también es necesario innovar bajo el paraguas de la sostenibilidad y tener presente la realidad social en la que se encuentra la empresa. Las personas ocupan un papel aun más protagonista en las organizaciones empresariales de sociedades avanzadas. La pedagogía no debe ni puede permanecer al margen. La formación, la capacitación, la cualificación, la capacidad de innovación y la vinculación de la persona con la organización son las claves para el desarrollo, crecimiento y supervivencia de las organizaciones empresariales. La formación debe colaborar desde una perspectiva pedagógica. No debe limitar su actuación a ámbitos externos de la empresa (antes de la incorporación de la persona, o cuando la persona no está en el mercado laboral). Debe actuar desde dentro de las organizaciones empresariales.

Models of initial training of secondary school teachers in Spain from a European perspective

This paper seeks to analyse some key issues related to initial training models for secondary education teachers from an international perspective with more specific references to the Spanish model. First, we briefly mention secondary education and its training needs: purpose, organization, structure, character, duration, etc.. Secondly, the most typical models of initial training of these teachers: consecutive and simultaneous, academic and professional, are adressed. Thirdly, we analyse the structure of initial training containing more general scientific and professional knowledge, (its theoretical and practical components). Lastly, the relationship between initial training and access to the teaching profession will be established, as well as the possibility of academic and / or professional qualifications is analyzed. We then highlight the issue of "professional identity", which is closely linked to the initial training of future teachers and final conclusions are discussed.

Reflexive learning in pre-service training of primary school teachers: from experience to assimilation of contents

This article presents an educational experiment carried out in the Primary School Teaching Degree at the University of Barcelona. Specifically, the article analyses the application of the “Work Corners” approach in a core subject. In a three-year action research process, trainers put into practice an innovation which enabled them to boost cooperative work and reflexive learning among trainees. Firstly, the theoretical model underpinning the project and guiding many of the actions carried out by the training team is presented. After providing detailed information on the practical development of the experiment, the data-gathering process and its results are shown. Various information-gathering strategies were used in assessing the project, such as a questionnaire, participant observation, and teachers’ diaries. The results demonstrate, amongst other things, that “work corners” offer viable and appropriate educational conditions for the articulation of theoretical and practical knowledge, for building professional knowledge, and therefore, the beginnings of a reflexive teaching practice.

¿Barreras invisibles? Actitudes de los estudiantes universitarios ante sus compañeros con discapacidad

El presente trabajo analiza los conocimientos, opiniones y actitudes de los estudiantes universitarios sobre sus compañeros con discapacidad. La integración educativa y social de estos estudiantes es objeto de preocupación y estudio en todo el sistema educativo español, incluida la enseñanza superior en la que 21.942 universitarios con discapacidad se encontraban matriculados en el curso 2013-2014. El estudio se realiza en el marco de dos Proyectos de Innovación Educativa[1] de la Universidad de Málaga en los que se examinaron las actitudes del personal docente e investigador, el alumnado en general y el alumnado con discapacidad de esta institución. En este artículo se recogen las perspectivas de los estudiantes sin discapacidad, necesarias para medir el grado de aceptación dentro de las aulas universitarias. Se empleó una encuesta suministrada mediante correo electrónico a la totalidad de la población de estudiantes de la Universidad de Málaga (N= 32.464). El tamaño de la muestra fue de 620 estudiantes, por lo que trabajamos con un margen de error del 3,9% para la estimación de los porcentajes con un nivel de confianza del 95%. Los datos, analizados mediante análisis estadístico, visibilizan la importancia de un elevado grado de información y conocimiento así como de una experiencia directa con la discapacidad. Ambas circunstancias se traducen en actitudes más positivas y favorables. Tan solo el 20% de los alumnos manifestó haber recibido en alguna ocasión cualquier tipo de información sobre este asunto por parte de la Universidad; no obstante, la mayoría valora positivamente la presencia de alumnos con discapacidad en la Universidad, la posibilidad de contar ellos como compañeros de clase y el enriquecimiento que supone esta convivencia dentro del aula. Se discuten posibles acciones para mejorar las actitudes hacia los estudiantes con discapacidad. Además, se plantea incluir una perspectiva que promueva el empoderamiento de estos estudiantes.

Social networks applied to training

In this article, we address the importance and relevance that social networks exhibit in their use as an educational resource.  This relevance relies in the possibility of implementing new learning resources or increasing the level of the participant's connectivity, as well as developing learning communities.  Also, the risk entailed from their use is discussed, especially for the students that have a low technological education or those having excessive confidence on the media.  It is important to highlight that the educational use of social networks is not a simple extension or translation of the student's habitual, recreational use, but that it implies an important change in the roles given to teachers as well as learners; from accommodative learning environments that only encourage memorization to other environments that demand an active, reflective, collaborative and proactive attitude, that require the development/acquisition of technological as well as social abilities, aptitudes and values.  It is also important to highlight that a correct implementation and adequate use will not only foment formal learning, but also informal and non-formal learning.
