Fog deposition, precipitation, throughfall and stemflow were measured in a windward tropical montane cloud forest near Monteverde, Costa Rica, for a 65-day period during the dry season of 2003. Net fog deposition was measured directly using the eddy covariance (EC) method and it amounted to 1.2 ± 0.1 mm/day (mean ± standard error). Fog water deposition was 5-9% of incident rainfall for the entire period, which is at the low end of previously reported values. Stable isotope concentrations (d18O and d2H) were determined in a large number of samples of each water component. Mass balance-based estimates of fog deposition were 1.0 ± 0.3 and 5.0 ± 2.7 mm/day (mean ± SE) when d18O and d2H were used as tracer, respectively. Comparisons between direct fog deposition measurements and the results of the mass balance model using d18O as a tracer indicated that the latter might be a good tool to estimate fog deposition in the absence of direct measurement under many (but not all) conditions. At 506 mm, measured water inputs over the 65 days (fog plus rain) fell short by 46 mm compared to the canopy output of 552 mm (throughfall, stemflow and interception evaporation). This discrepancy is attributed to the underestimation of rainfall during conditions of high wind.

The data collection "Deep Drilling of Glaciers: Soviet-Russian projects in Arctic, 1975-1995" was collected by the following basic considerations: - compilation of deep (>100 m) drilling projects on Arctic glaciers, using data of (a) publications; (b) archives of IGRAN; (c) personal communication of project participants; - documentation of parameters, references. Accuracy of data and techniques applied to determine different parameters are not evaluated. The accuracy of some geochemical parameters (up to 1984 and heavy metalls) is uncertain. Most reconstructions of ice core age and of annual layer thickness are discussed; - digitizing of published diagrams (in case, when original numerical data were lost) and subsequent data conversion to equal range series and adjustment to the common units. Therefore, the equal-range series were calculated from original data or converted from digitized chart values as indicated in the metadata. For the methodological purpose, the equal-range series obtained from original and reconstructed data were compared repeatedly; the systematic difference was less then 5-7%. Special attention should be given to the fact, that the data for individual ice core parameters varies, because some parameters were originally measured or registered. Parameters were converted in equal-range series using 2 m steps; - two or more parameter values were determined, then the mean-weighted (i.e. accounting the sample length) value is assigned to the entire interval; - one parameter value was determined, measured or registered independently from the parameter values in depth intervals which over- and underlie it, then the value is assigned to the entire interval; - one parameter value was determined, measured or registered for two adjoining depth intervals, then the specific value is assigned to the depth interval, which represents >75% of sample length ; if each of adjoining depth intervals represents <75% of sample length, then the correspondent parameter value is assigned to both intervals of depth. This collection of ice core data (version 2000) was made available through the EU funded QUEEN project by S.M. Arkhipov, Moscow.

Este trabajo de investigación se enmarca en el Proyecto Impacto territorial de los cambios y permanencias de la estructura agraria de la provincia de Santa Fe a partir de los '90 y sus consecuencias demográficas del Programa CAI+D 2006 de la UNL, y es una primera aproximación al estudio de propuestas de enseñanza de geografía rural. Se ha trabajado con una metodología cualitativa interpretativa, a través del análisis documental de las siguientes fuentes: Diseños Curriculares Jurisdiccionales, manuales escolares, planificaciones anuales de docentes y registros etnográficos de clases realizados en el marco de la asignatura Didáctica de la Geografía. El análisis nos ha permitido identificar la presencia y la ausencia de conceptos, temáticas y enfoques metodológicos en las propuestas de enseñanza referidas a los espacios rurales realizadas por profesores de Geografía de la provincia de Santa Fe.

This work belongs to the Project "Teaching and learning Psychology: a study of the educational practice in professors and beginners". It is part of an investigation program developed in the context of the subject "Didactic and Practical Planning of Psychology teaching" in which we have been working since 1998. This subject is also considered as the final stage of the formative itinerary for Psychology s professors. The reached results show the incidence that the beliefs and professors' representations have in the teaching processes. By getting into the studies centered in the educational knowledge we guide the inquiry around the development of the professor's professional knowledge and particularly the development of their formation. Our proposal contemplates a formation device which incorporates the observation, reflection, evaluation and self-evaluation of the practice in order to facilitate the reconstruction, significance and re-significance of the teaching and learning processes by giving relevance to the development of the teacher professional knowledge. The analysis of teaching practices process reveals that the mediations that cross the knowledge in the being taught instances are constituted in reflections axes. This involves the future professor's relationship with the knowledge and their projection in the construction of the professional identity.

Alejandro Kaufman (2008) señala que grandes transformaciones se están produciendo desde una perspectiva histórico - cultural en la relación que se establece entre la educación y la sociedad. Y que muchas de las tensiones entre ambas son el producto de lo que denomina "novedades" culturales. Sostiene que la educación se ha sustentado en una cierta previsibilidad y que, en cuanto que la modernidad representa progreso, el cual estaría asociado a la desaparición o transformación de muchas de esas certidumbres, la escuela estaría sufriendo ciertas modificaciones que involucran los propios cimientos de la institución escolar. La formación de los futuros maestros en el área de Ciencias Sociales debe ser ajustada a los requerimientos de esta nueva sociedad. El abordaje de la Didáctica de las Ciencias Sociales debe considerar las nuevas aproximaciones epistemológicas y temáticas relevantes en las propuestas pedagógicas. Es indispensable que, así como existen contenidos de Geografía en los planes de estudio de los profesorados y profusas indicaciones para su tratamiento en los diseños curriculares de Primero y Segundo ciclo, se verifique el desarrollo de los mismos desde una mirada crítica que permita tanto a docentes como alumnos un compromiso con el mundo en el que la escuela está inserta

En la actualidad, la reconfiguración y re-significación de las formas tradicionales de alimentación no sólo pasan por el proceso de producción de comidas, sino también por su adaptación a ciertas formas globalizadas de consumo y sociabilidad (comida rápida) características de la vida urbana. La presente propuesta fue desarrollada con los alumnos del Colegio Secundario dependiente de la UNICEN Colegio Nacional Ernesto Sabato. Es un trabajo relacionado con el espacio social del consumo, para el que se empleó la perspectiva cualitativa en ciencias humanas para su análisis e interpretación en la geografía escolar. A través de la proyección de la película "Super Size Me", como estrategia didáctica, se exploran las complejas relaciones entre el consumo, el territorio y la sociedad, en el actual contexto de crecientes prácticas sociales de consumo del mundo y del lugar. El trabajo constituye una aproximación cualitativa desde las imágenes visuales móviles a los comportamientos de los consumidores, sus motivaciones y hábitos en el consumo, en los espacios de recreación y consumo de comidas en el medio urbano
