En España se han usado distintas modalidades de perfeccionamiento del profesorado en ejercicio, que combinan elementos pertenecientes a la microenseñanza y a los sistemas de análisis de interacción. David del Prado, del ICE de la Universidad de Santiago de Compostela, y Luis Miguel Villar Angulo diseñaron un cuestionario encaminado a sintetizar las realizaciones de los distintos Institutos de Ciencias de la Educación en materia de microenseñanza, análisis de interacción y CCTV aplicado a la formación del profesorado. El objetivo era sistematizar los enfoques e instrumentos de formación del profesorado utilizados en la red ICE-INCIE. 18 centros estudiados. 13 usaban técnicas de microenseñanza en la formación y perfeccionamiento de los profesores. Solamente 11 institutos contestaron al cuestionario. Las respuestas corresponden a los años 1974-1975. Los datos sobre los restantes ICE se obtuvieron consultando la literatura pertinente: memorias de los ICE, proyectos de investigación, artículos de revistas, monografías, comunicaciones y ponencias, etc..

La autora, tras revisar las teorías sobre la adquisición de la multiplicación, el proceso de construcción de las relaciones multiplicativas, y partiendo de una experiencia con niños sobre la utilización del algoritmo tipo red (S. XV) para un mejor aprendizaje de la multiplicación aritmética, inicia su investigación partiendo de la hipótesis de que este método basado en el producto cartesiano, se ajusta mejor a las estructuras del pensamiento, y por tanto, permite una mejor comprensión también en sujetos adultos. Compuesta por 17 sujetos entre 26 y 52 años, 16 mujeres y 1 hombre, pertenecientes a Educación Permanente de Adultos de Elda (Alicante), aunque la investigación sólo la finalizaron 4 sujetos por muerte experimental del 76'5 por ciento. La investigación utiliza un diseño de pretest-postest. Pruebas 'ad hoc' utilizadas en el pretest-postest que consistían en una serie de ítems que, independientemente dan información sobre los distintos aspectos de la multiplicación. Programa escolar utilizado para la enseñanza de la multiplicación. Resolución de problemas reales, cotidianos, de los sujetos por medio de la operación de multiplicar. Análisis cualitativo de los datos comparados en el pretest y el postest, enumeración de los progresos y/o estancamientos de los sujetos de la investigación. El método del algoritmo en red sí permite la capacitación de los individuos pues posibilita la construcción de estructuras multiplicativas. Desde el punto de vista empírico esto es válido, aunque, en los sujetos de esta investigación, debido a sus especiales características no ha podido ser discriminativo para la comprobación de la hipótesis. Aunque el algoritmo empleado ha favorecido la comprensión de la multiplicación, no ha motivado suficientemente a los sujetos por diversos motivos: A) No se ajusta a sus intereses que son el aprendizaje de las tablas de multiplicar. B) Confunden rapidez con efectividad. C) No tiene relación con las nociones anteriores sobre el tema. D) Siguen anclados en estructuras aditivas por lo que no encuentran significado a otra entidad matemática.

Se explican cu??les son los elementos que deben intervenir en una escuela promotora de salud para cumplir con la finalidad de impulsar y fomentar los modos de vida sanos entre sus miembros. Se debe poner en pr??ctica el curr??culo de educaci??n para la salud, en el cuidado del entorno f??sico y social de la escuela para que ??ste sea coherente con los contenidos de aprendizaje que se trabajan (cultura, sistema de valores, organizaci??n escolar...); y en la planificaci??n y puesta e marcha de estrategias de relaci??n y coordinaci??n con las familias y con la comunidad en la que est?? inmersa.

The period following the withdrawal of parental care has been highlighted as a key developmental period for juveniles. One reason for this is that juveniles cannot forage as competently as adults, potentially placing them at greater risk from environmentally-induced changes in food availability. However, no study has examined this topic. Using a long-term dataset on red foxes (Vulpes vulpes), we examined (i) dietary changes that occurred in the one-month period following the attainment of nutritional independence, (ii) diet composition in relation to climatic variation, and (iii) the effect of climatic variation on subsequent full-grown mass. Diet at nutritional independence contained increased quantities of easy-to-catch food items (earthworms and insects) when compared with pre-independence. Interannual variation in the volume of rainfall at nutritional independence was positively correlated to the proportion of earthworms in cub diet. Pre-independence cub mass and rainfall immediately following nutritional independence explained a significant proportion of variance in full-grown mass, with environmental variation affecting full-grown mass of the entire cohorts. Thus, weather-mediated availability of easy-to-catch food items at a key developmental stage has lifelong implications for the development of juvenile foxes by affecting full-grown mass, which in turn appears to be an important component of individual reproductive potential.

Traffic collisions can be a major source of mortality in wild populations, and animals may be expected to exhibit behavioral mechanisms that reduce the risk associated with crossing roads. Animals living in urban areas in particular have to negotiate very dense road networks, often with high levels of traffic flow. We examined traffic-related mortality of red foxes (Vulpes vulpes) in the city of Bristol, UK, and the extent to which roads affected fox activity by comparing real and randomly generated patterns of movement. There were significant seasonal differences in the number of traffic-related fox deaths for different age and sex classes; peaks were associated with periods when individuals were likely to be moving through unfamiliar terrain and would have had to cross major roads. Mortality rates per unit road length increased with road magnitude. The number of roads crossed by foxes and the rate at which roads were crossed per hour of activity increased after midnight when traffic flow was lower. Adults and juveniles crossed 17% and 30% fewer roads, respectively, than expected from randomly generated movement. This highly mobile species appeared to reduce the mortality risk of minor category roads by changing its activity patterns, but it remained vulnerable to the effects of larger roads with higher traffic flows during periods associated with extraterritorial movements.

Red leaf lettuce (Lollo Rosso) was grown under three types of plastic films that varied in transparency to UV radiation (designated as UV block, UV low, and UV window). Flavonoid composition was determined by high-performance liquid chromatography (HPLC), total phenolics by the Folin-Ciocalteu assay, and antioxiclant capacity by the oxygen radical absorbance capacity (ORAC) assay. Exposure to increased levels of UV radiation during cultivation caused the leaves to redden and increased concentrations of total phenols and the main flavonoids, quercetin and cyanidin glycosides, as well as luteolin conjugates and phenolic acids. The total phenol content increased from 1.6 mg of gallic acid equivalents (GAE)/g of fresh weight (FW) for lettuce grown under UV block film to 2.9 and 3.5 mg of GAE/g of FW for lettuce grown under the UV low and UV window films. The antioxiclant activity was also higher in lettuce exposed to higher levels of UV radiation with ORAC values of 25.4 and 55.1 mu mol of Trolox equivalents/g of FW for lettuce grown under the UV block and UV window films, respectively. The content of phenolic acids, quantified as caffeic acid, was also different, ranging from 6.2 to 11.1 mu mol/g of FW for lettuce cultivated under the lowest and highest UV exposure plastic films, respectively. Higher concentrations of the flavonoid glycosides were observed with increased exposure to UV radiation, as demonstrated by the concentrations of aglycones after hydrolysis, which were cyanidin (ranging from 165 to 793 mu g/g), quercetin (ranging from 196 to 880,mu g/g), and luteolin (ranging from 19 to 152 mu g/g). The results demonstrate the potential of the use of UV-transparent plastic as a means of increasing beneficial flavonoid content of red leaf lettuce when the crop is grown in polytunnels.
