Emprender juntos un camino.

Se trata de un proyecto llevado a cabo en el CEIP Curtis (A Coruña) con un grupo de niños de tres años que inician la Educación Infantil y una maestra que se acaba de incorporar al colegio. El proyecto `A miña historia´pretende, através de la reconstrucción de la historia personal, conectar familia y escuela y aportar seguridad a los niños. Una vez conseguidos estos objetivos iniciales, mediante distintas actividades, se van desarrollando las distintas áreas del currículo.

En busca de nuestra identidad

Se trata de una experiencia llevada acabo por los alumnos de cuatro años de Educación Infantil del CEIP Curtis, de Curtis (A Coruña). El proyecto se inicia con los pintores para posteriormente trabajar la prehistoria. En el artículo se explica el proceso de enseñanza aprendizaje.

La educación sexual colectiva en Estados Unidos.

Se describe la situación de la educación sexual en los Estados Unidos. La característica esencial es la falta de uniformidad en los diferentes Estados. Esta uniformidad afecta a su obligatoriedad, ya que mientras en unos estados la educación sexual es obligatoria, en otros no se imparte; también afecta a su contenido y al modo de impartir las clases. Por otro lado se pone de manifiesto la importancia de la cuestión sexual en Estados Unidos, en un momento en que parece producirse una invasión de lo sexual, y de un desplazamiento hacia la moral hedonista, sobre todo en los más jóvenes, que tendrá consecuencias negativas. Se dan una serie de datos para demostrar estas afirmaciones, recogidos de distintas publicaciones norteamericanas. También se hace referencia a las tres etapas en que Curtis E. Avery, divide la educación sexual en EstadosUnidos. La primera etapa es en los años anteriores a los 50, de clara oposición a una educación sexual en las escuelas. Del año1950 al 1960, tras quedar en evidencia una creciente actividad sexual entre los jóvenes, se impulsa una educación sexual que suponga un remedio preventivo. La tercera etapa se inicia hacia1965, cuando se hace evidente la necesidad de una educación sexual más completa. Posteriormente se señalan los nuevos enfoques que sigue la educación sexual en estos últimos años de la década de los 60: integración de los múltiples valores que integran la educación sexual, que van más allá de los contenidos puramente biológicos; valor positivo, a quienes corresponde el cometido de la educación sexual y programación. Por último se señalan una serie de medios auxiliares, como los documentales, y los discos y cintas magnetofónicas.

Variables associated with nest survival of Golden-winged Warblers (Vermivora chrysoptera) among vegetation communities commonly used for nesting

Among shrubland- and young forest-nesting bird species in North America, Golden-winged Warblers (Vermivora chrysoptera) are one of the most rapidly declining partly because of limited nesting habitat. Creation and management of high quality vegetation communities used for nesting are needed to reduce declines. Thus, we examined whether common characteristics could be managed across much of the Golden-winged Warbler’s breeding range to increase daily survival rate (DSR) of nests. We monitored 388 nests on 62 sites throughout Minnesota, Wisconsin, New York, North Carolina, Pennsylvania, Tennessee, and West Virginia. We evaluated competing DSR models in spatial-temporal (dominant vegetation type, population segment, state, and year), intraseasonal (nest stage and time-within-season), and vegetation model suites. The best-supported DSR models among the three model suites suggested potential associations between daily survival rate of nests and state, time-within-season, percent grass and Rubus cover within 1 m of the nest, and distance to later successional forest edge. Overall, grass cover (negative association with DSR above 50%) and Rubus cover (DSR lowest at about 30%) within 1 m of the nest and distance to later successional forest edge (negative association with DSR) may represent common management targets across our states for increasing Golden-winged Warbler DSR, particularly in the Appalachian Mountains population segment. Context-specific adjustments to management strategies, such as in wetlands or areas of overlap with Blue-winged Warblers (Vermivora cyanoptera), may be necessary to increase DSR for Golden-winged Warblers.

The biometeorology of high-altitude insect layers.

Flight at high altitude is part of a migration strategy that maximises insect population displacement. This thesis represents the first substantial analysis of insect migration and layering in Europe. Vertical-looking entomological radar has revealed specific characteristics of high-altitude flight: in particular layering (where a large proportion of the migrating insects are concentrated in a narrow altitude band). The meteorological mechanisms underpinning the formation of these layers are the focus of this thesis. Aerial netting samples and radar data revealed four distinct periods of high-altitude insect migration: dawn, daytime, dusk, and night-time. The most frequently observed nocturnal profiles during the summertime were layers. It is hypothesised that nocturnal layers initiate at a critical altitude (200–500 m above ground level) and time (20:00–22:00 hours UTC). Case study analysis, statistical analysis, and a Lagrangian trajectory model showed that nocturnal insect layers probably result from the insects’ response to meteorological conditions. Temperature was the variable most correlated with nocturnal insect layer presence and intensity because insects are poikilothermic, and temperatures experienced during high-altitude migration in temperate climates are expected to be marginal for many insects’ flight. Hierarchical effects were detected such that other variables—specifically wind speed—were only correlated with insect layer presence and intensity once temperatures were warm. The trajectory model developed comprised: (i) insect flight characteristics; (ii) turbulent winds (which cause vertical spread of the layer); and (iii) mean wind speed, which normally leads to horizontal displacements of hundreds of kilometres in a single migratory flight. This thesis has revealed that there is considerable migratory activity over the UK in the summer months, and a range of fascinating phenomena can be observed (including layers). The UK has moved from one of the least studied to perhaps the best studied environments of aerial insect migration and layering in the world.

Dispersion Experiments in Central London: The 2007 DAPPLE project

In the event of a release of toxic gas in the center of London, the emergency services would need to determine quickly the extent of the area contaminated. The transport of pollutants by turbulent flow within the complex street and building architecture of cities is not straightforward, and we might wonder whether it is at all possible to make a scientifically-reasoned decision. Here we describe recent progress from a major UK project, ‘Dispersion of Air Pollution and its Penetration into the Local Environment’ (DAPPLE, www.dapple.org.uk). In DAPPLE, we focus on the movement of airborne pollutants in cities by developing a greater understanding of atmospheric flow and dispersion within urban street networks. In particular, we carried out full-scale dispersion experiments in central London (UK) during 2003, 2004, 2007, and 2008 to address the extent of the dispersion of tracers following their release at street level. These measurements complemented previous studies because (i) our focus was on dispersion within the first kilometer from the source, when most of the material was expected to remain within the street network rather than being mixed into the boundary layer aloft, (ii) measurements were made under a wide variety of meteorological conditions, and (iii) central London represents a European, rather than North American, city geometry. Interpretation of the results from the full-scale experiments was supported by extensive numerical and wind tunnel modeling, which allowed more detailed analysis under idealized and controlled conditions. In this article, we review the full-scale DAPPLE methodologies and show early results from the analysis of the 2007 field campaign data.
