A l'abast : comunicació bàsica en llengua catalana : comunicación básica en lengua catalana : basic communication in the catalan language : communication basique en langue catalane. 'Al alcance : comunicación básica en lengua catalana'.

Pensado para las personas no catalanoparlantes que, tanto si han decidido convertir las islas en su lugar de residencia como si no es el caso, tienen la inquietud de acercarse a esta realidad lingüística y cultural. Pretende facilitar la adquisición de una serie de recursos útiles para una comunicación básica en lengua catalana. Consiste en un conjunto de frases frecuentes en situaciones usuales de la vida cotidiana. El texto escrito se complementa con un cd-rom que permite escuchar estas frases pronunciadas por hablantes nativos y registrar y escuchar aquellas que produce el alumno. No es un curso de catalán, es sólo una aproximación a la lengua catalana que debe estimular a aprender más. Incluye también una guía de recursos para aprender catalán desde las Islas Baleares: cursos, centros de autoaprendizaje, recursos en soporte informático o accesibles a través de Internet, que se adaptan a las necesidades de todos los que desean aprender esta lengua.

Conceptuals Mentefactos as a Didactic-Pedagogical Strategy of the Basic Concepts in the Sampling Theory Applyed to the Health Research

In populational sampling it is vitally important to clarify and discern: first, the design or sampling method used to solve the research problem; second, the sampling size, taking into account different components (precision, reliability, variance); third, random selection and fourth, the precision estimate (sampling errors), so as to determine if it is possible to infer the obtained estimates from the target population. The existing difficulty to use concepts from the sampling theory is to understand them with absolute clarity and, to achieve it, the help from didactic-pedagogical strategies arranged as conceptual “mentefactos” (simple hierarchic diagrams organized from propositions) may prove useful. This paper presents the conceptual definition, through conceptual “mentefactos”, of the most important populational probabilistic sampling concepts, in order to obtain representative samples from populations in health research.

The role of the basic state in the ENSO-monsoon relationship and implications for predictability

The impact of systematic model errors on a coupled simulation of the Asian Summer monsoon and its interannual variability is studied. Although the mean monsoon climate is reasonably well captured, systematic errors in the equatorial Pacific mean that the monsoon-ENSO teleconnection is rather poorly represented in the GCM. A system of ocean-surface heat flux adjustments is implemented in the tropical Pacific and Indian Oceans in order to reduce the systematic biases. In this version of the GCM, the monsoon-ENSO teleconnection is better simulated, particularly the lag-lead relationships in which weak monsoons precede the peak of El Nino. In part this is related to changes in the characteristics of El Nino, which has a more realistic evolution in its developing phase. A stronger ENSO amplitude in the new model version also feeds back to further strengthen the teleconnection. These results have important implications for the use of coupled models for seasonal prediction of systems such as the monsoon, and suggest that some form of flux correction may have significant benefits where model systematic error compromises important teleconnections and modes of interannual variability.
