Incidencia de la experiencia docente con el TDAH en los conocimientos, la autoeficacia y los niveles de estrés docente
2020
Los estudios que han comparado los conocimientos que tienen los profesores sin experiencia (PSE) y los profesores con experiencia profesional (PCE) sobre el Trastorno por Déficit de Atención e Hiperactividad (TDAH) han mostrado resultados contradictorios. Además, el papel que tiene la experiencia docente con niños con TDAH sobre los conocimientos, la autoeficacia y el estrés docente no ha sido abordado en los estudios previos. Por ello, el presente estudio pretende: a) comparar los conocimientos, las creencias erróneas y las lagunas de conocimiento de los PCE y PSE de España, acerca del TDAH; b) analizar la experiencia de los PCE con niños con TDAH y la relación con los conocimientos, la au…
In Itinere STRATEGIC ENVIRONMENTAL ASSESSMENT of an integrated provincial waste system
2009
In the paper, the practical problem of analysing in an integrated way the performance of provincial waste systems is approached, in the framework of the Strategic Environmental Assessment (SEA). In particular, the in itinere phase of SEA is analysed herein. After separating out a proper group of ambits, to which the waste system is supposed to determine relevant impacts, pertinent sets of single indicators are proposed. Through the adoption of such indicators the time trend of the system is investigated, and the suitability of each indicator is critically revised. The structure of the evaluation scheme, which is essentially based on the use of ambit issues and analytical indicators, calls …
Precursors of Body Dissatisfaction and its Implication for Psychological Well-Being in Young Adults
2019
The authors examined leisure-time physical activity (LTPA), body mass index (BMI), and perceived physical ability as body dissatisfaction antecedents, and analyzed their relationship to well-being. The sample comprised 501 university students. Data were collected using a self-administered survey. Path analysis revealed that LTPA positively predicted perceived physical ability. BMI and perceived physical ability predicted body dissatisfaction (positively and negatively, respectively). Body dissatisfaction negatively predicted subjective vitality, whereas perceived physical ability positively predicted subjective vitality. These results support the inclusion of LTPA in intervention programs t…
From the many voices to the subject positions in anti-globalization discourse: Enunciative pragmatics and the polyphonic organization of subjectivity
2011
This contribution presents enunciative pragmatics as a methodological orientation to account for how written texts are contextualized in the act of reading. As an offspring of the pragmatic turn among French-speaking linguists, the enunciative approach is mobilized to analyze the cover page of a cartoon on the anti-globalization legend Jose Bove. Focusing on the complex interpretive problems of political discourse, the enunciative-pragmatic approach shows how readers construct subject positions following the text's complex indexicality. It reveals the polyphonic play of voices orchestrated by the enunciative markers. Therefore, enunciative pragmatics promises to bridge the gulf that separat…
Compared regimes of NDVI and Rainfall in semi-arid regions of Africa
2006
International audience; Bi-monthly normalized difference vegetation index (NDVI) at an 8km spatial resolution from the advanced very high resolution radiometers (AVHRR) was used from 1981 to 1995 to analyse the vegetation response to rainfall supply in semi-arid regions of Africa. Within the 200-600 mm annual rainfall belt, for which the apparent NDVI response to rainfall was the strongest, three regions were selected which exhibited different patterns in their NDVI regimes and/or relationships with rainfall. The regions, located in western, southern and eastern Africa, were split into coherent sub-regions in terms of mean regime of photosynthetic activity through a cluster analysis. Overal…
Near‐field optical addressing of single molecules in coplanar geometry: a theoretical study
2001
Photonic transfer through elongated optical structures of submicrometre section microfabricated at the surface of dielectric or semiconductor samples can be enhanced by an appropriate structuring of the local refraction index. We show from computerized simulations that both the light localization and the spectroscopic properties of such structures can be used to selectively excite, in coplanar geometry, individuals molecules located in the near-field.
Land surface emissivity retrieval from different VNIR and TIR sensors
2008
This paper discusses the application and adaptation of two existing operational algorithms for land surface emissivity (epsiv) retrieval from different operational satellite/airborne sensors with bands in the visible and near-infrared (VNIR) and thermal IR (TIR) regions: (1) the temperature and emissivity separation algorithm, which retrieves epsiv only from TIR data and (2) the normalized-difference vegetation index thresholds method, in which epsiv is retrieved from VNIR data.
Surface emissivity retrieval from Digital Airborne Imaging Spectrometer data
2002
[1] A study has been carried out on the most recent algorithms for the estimation of land surface emissivity (e) using high-resolution data (Digital Airborne Imaging Spectrometer, DAIS) over the Rhine Valley (France) and Castilla La Mancha (Spain). Three published methods have been applied for extracting absolute spectral emissivity information from images recorded during the DAISEX experiment in 1999. They are NDVI Thresholds Method (NDVITHM), Normalized Emissivity Method (NEM) and Temperature/Emissivity Separation (TES). These lather two methods were originally designed to work over geological surfaces. Five methods have been used for extracting relative spectral emissivity. They are temp…
Land surface emissivity retrieval from airborne sensor over urban areas
2012
Abstract In this paper we compare three different methodologies to retrieve land surface emissivity (LSE) over urban areas: the NDVI thresholds method, the temperature and emissivity separation (TES) algorithm and the temperature independent spectral indices (TISI) algorithm. The methodologies were applied to the Airborne Hyperspectral Scanner (AHS) imagery acquired during the Dual-use European Security IR Experiment 2008 (DESIREX 2008) experimental campaign over the city of Madrid (Spain). The images have a spatial resolution of 4 m. The retrieved values are compared to in situ data measured during the campaign at 4 sites. Results show a good performance of the TISI and the TES algorithms …
A proposed equation of correlation for the study of thermodynamic properties (density, viscosity, surface tension and refractive index) of liquid bin…
2009
Abstract The literature on the physicochemical properties of liquid binary mixtures shows that most such systems exhibit nonlinear behavior. As a result, rigorous data and equations capable of affording a reliable estimate of the behavior of such mixtures are needed. The present study offers an equation of correlation providing a reliable estimation of the properties (density, viscosity, surface tension and refractive index) of binary mixtures of liquids as a function of mole fraction. In order to assess the validity of the proposed equation, the latter has been applied to reference binary mixtures, and comparisons have been made of the experimental values of the studied magnitudes versus t…
