La hipótesis fundamental de este trabajo es que la práctica de la rapidez de reacción en los ejercicios y juegos con movimiento virtual es independiente de la velocidad de anticipación y como hipótesis secundaria plantea que la práctica de la rapidez de reacción en los ejercicios y juegos con movimiento virtual es independiente de la velocidad de anticipación en las subpoblaciones definidas por las variables género, edad, rendimiento académico, tipo de centro al que asisten a clase y tendencia al adelanto o retraso en la velocidad de anticipación. La muestra se encuentra constituida por 500 individuos tomados de la población de la Comunidad de Madrid comprendida entre los 10 y los 18 años, elegida por muestreo incidental aleatorio. A continuación paso a definir diferentes variables que intervienen en el estudio: 1. Captación de la relación espacio-temporal, la tendencia de adelanto, la edad, el género, etc. Los instrumentos utilizados para llevar a cabo la presente investigación han sido los siguientes: Test K.C.C., paquete estadístico SPSS (versión 12 en español) y un aparato constituido por una caja metálica con diversos interruptores y circuitos electrónicos en su interior. Los resultados verifican que la hipótesis de que no hay relación entre la velocidad de reacción y la capacidad para procesar relaciones espacio-temporales. La práctica de la rapidez de reacción en los ejercicios y juegos con movimiento virtual es independiente de la velocidad de anticipación. Se llevo a cabo un estudio detenido para comprobar la posibilidad de incidencia en la hipótesis de otras variables controladas, la cual no se ha encontrado (a = 0,01) en función de: a) género; b) edad; c) tipo de centro al que asisten a clase; d) rendimiento académico; ni e) tendencia al adelanto o retraso en la velocidad de anticipación. Por otra parte, se ha encontrado que existe correlación entre la velocidad de anticipación y el tiempo dedicado al estudio. Los resultados que se han obtenido apoyan las razones encontradas en otras investigaciones para considerar la velocidad de anticipación como un tipo de atención interna procesual o de inteligencia cinética.

(INFINITIVE + CLITIC + AUX) is an evidential configuration in Old Spanish and Old Catalan, whereas (PARTICIPLE + CLITIC + AUX) is an instance of weak or unmarked focus fronting. The evidentiality of mesoclitic structures can be put forward on the bases of three main arguments: a) mesoclisis is not compulsory (i.e., whenever you have a clitic, you can either have mesoclisis or proclisis/enclisis); b) mesoclitic futures and conditionals are attested in interrogative sentences (with wh- elements); and c) they are not found in derived adverbial clauses (which is what you expect if they have an evidential value, since they bring about intervention effects corresponding to the derivational account of conditional and temporal sentences, for example - see Haegeman 2007 and ff.), and are related to high modal expressions (thus interfering with MoodPIrrealis)

Temporal processing is examined for sounds delivered to the intact ear of individuals with unilateral hearing, and delivered to one ear of individuals with normal, bilateral hearing. Two temporal processing skills are assessed: 1) the ability to detect sinusoidal amplitude modulation of a wide-band noise, for various modulation frequencies, and 2) the just-noticeable-difference for temporal complexity of random-spectrogram-sounds.

Experiments explored the minimal kanamycin dosing regimen that renders protection against noise induced hearing loss in young CBA/J mice. We also tested the age-dependence of protection in CBA/J as well as the dependence of protection on a particular genetic background in experiments using young C57BL/6J and CBA/CaJ mice.

La presente investigación tiene por objeto analizar el manejo tributario de los arrendamientos mercantiles y del régimen especial de admisión temporal. Se analiza la evolución del Leasing, determinando que el Ecuador fue uno de los primeros países en Latinoamérica en regular el Leasing; sin embargo, esta normativa no ha evolucionado, por lo que se examina la normativa tributaria vigente. Los Arrendamientos Mercantiles Financieros, permiten el financiamiento del 100% de los bienes de capital, opera a través de un contrato, en donde una compañía autorizada o una institución del sistema financiero, adquiere un bien de capital de acuerdo a las características especificadas por el arrendatario, recibiendo un canon mensual durante un plazo determinado; y que al terminar éste, podrá optar entre continuar el contrato en nuevas condiciones, adquirir los bienes por un precio residual, devolver los bienes o participar del precio de venta a un tercero. Además, se dan a conocer las ventajas que tiene el Arrendamiento Financiero como herramienta de financiamiento. Con referencia a los Regímenes Especiales de Admisión Temporal, se revisa la base tributaria en cuanto al Impuesto al Valor Agregado, debido a que en el Régimen de Admisión Temporal con Reexportación en el mismo Estado, se presenta un pago doble, de acuerdo a lo que dispone el Reglamento para la Aplicación de la Ley de Régimen Tributario Interno y a la Ley Orgánica de Aduanas con referencia a la depreciación, que constituye la base imponible para el cálculo del Impuesto al Valor Agregado.

ATSR-2 active fire data from 1996 to 2000, TRMM VIRS fire counts from 1998 to 2000 and burn scars derived from SPOT VEGETATION ( the Global Burnt Area 2000 product) were mapped for Peru and Bolivia to analyse the spatial distribution of burning and its intra- and inter-annual variability. The fire season in the region mainly occurs between May and October; though some variation was found between the six broad habitat types analysed: desert, grassland, savanna, dry forest, moist forest and yungas (the forested valleys on the eastern slope of the Andes). Increased levels of burning were generally recorded in ATSR-2 and TRMM VIRS fire data in response to the 1997/1998 El Nino, but in some areas the El Nino effect was masked by the more marked influences of socio-economic change on land use and land cover. There were differences between the three global datasets: ATSR-2 under-recorded fires in ecosystems with low net primary productivities. This was because fires are set during the day in this region and, when fuel loads are low, burn out before the ATSR-2 overpass in the region which is between 02.45 h and 03.30 h. TRMM VIRS was able to detect these fires because its overpasses cover the entire diurnal range on a monthly basis. The GBA2000 product has significant errors of commission (particularly areas of shadow in the well-dissected eastern Andes) and omission (in the agricultural zone around Santa Cruz, Bolivia and in north-west Peru). Particular attention was paid to biomass burning in high-altitude grasslands, where fire is an important pastoral management technique. Fires and burn scars from Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM) data for a range of years between 1987 and 2000 were mapped for areas around Parque Nacional Rio Abiseo (Peru) and Parque Nacional Carrasco (Bolivia). Burn scars mapped in the grasslands of these two areas indicate far more burning had taken place than either the fires or the burn scars derived from global datasets. Mean scar sizes are smaller and have a smaller range in size between years the in the study area in Peru (6.6-7.1 ha) than Bolivia (16.9-162.5 ha). Trends in biomass burning in the two highland areas can be explained in terms of the changing socio-economic environments and impacts of conservation. The mismatch between the spatial scale of biomass burning in the high-altitude grasslands and the sensors used to derive global fire products means that an entire component of the fire regime in the region studied is omitted, despite its importance in the farming systems on the Andes.

Leaf-cutting ants consume up to 10% of canopy leaves in the foraging area of their colony and therefore represent a key perturbation in the nutrient cycle of tropical forests. We used a chronosequence of nest sites on Barro, Colorado Island, Panama, to assess the influence of leaf-cutting ants (Atta colombica) on nutrient availability in a neotropical rainforest. Twelve nest sites were sampled, including active nests, recently abandoned nests (<1 year) and long-abandoned nests (>1 year). Waste material discarded by the ants down-slope from the nests contained large concentrations of nitrogen and phosphorus in both total and soluble forms, but decomposed within one year after the nests were abandoned. Despite this, soil under the waste material contained high concentrations of nitrate and ammonium that persisted after the disappearance of the waste, although soluble phosphate returned to background concentrations within one year of nest abandonment. Fine roots were more abundant in soil under waste than control soils up to one year after nest abandonment, but were not significantly different for older sites. In contrast to the waste dumps, soil above the underground nest chambers consistently contained lower nutrient concentrations than control soils, although this was not statistically significant. We conclude that the 'islands of fertility' created by leaf-cutting ants provide a nutritional benefit to nearby plants for less than one year after nest abandonment in the moist tropical environment of Barro Colorado Island.
