El incremento del desarrollo moral en las clases de educación física.

[ES] El objetivo fundamental de este trabajo es evaluar la eficacia de un programa de Educación Física para el fomento del desarrollo moral. El trabajo se fundamenta en las teorías del desarrollo evolutivo de Piaget y Kholberg. Se ha utilizado metodología observacional, selectiva y cualitativa. La didáctica empleada en los grupos experimentales está basada en estrategias propias del desarrollo estructural, (discusión de dilemas morales, diálogos, búsqueda de acuerdos). Cada curso experimental ha utilizado un tipo de tarea distinta (psicomotrices, de cooperación o de cooperación–oposición). esultados indican que existe un aumento de las Conductas Positivas y del razonamiento moral en los grupos experimentales. Las hipótesis de partida se confirman existiendo una mayor frecuencia de Conductas Positivas en el curso de Cooperación–Oposición.

The EPICA Dronning Maud Land deep drilling operation

We report on the EPICA Dronning Maud Land (East Antarctica) deep drilling operation. Starting with the scientific questions that led to the outline of the EPICA project, we introduce the setting of sister drillings at NorthGRIP and EPICA Dome C within the European ice-coring community. The progress of the drilling operation is described within the context of three parallel, deep-drilling operations, the problems that occurred and the solutions we developed. Modified procedures are described, such as the monitoring of penetration rate via cable weight rather than motor torque, and modifications to the system (e.g. closing the openings at the lower end of the outer barrel to reduce the risk of immersing the drill in highly concentrated chip suspension). Parameters of the drilling (e.g. core-break force, cutter pitch, chips balance, liquid level, core production rate and piece number) are discussed. We also review the operational mode, particularly in the context of achieved core length and piece length, which have to be optimized for drilling efficiency and core quality respectively. We conclude with recommendations addressing the design of the chip-collection openings and strictly limiting the cable-load drop with respect to the load at the start of the run.
