Competències del professorat a Europa (2). Competències reals i competències desitjades. Procés de recerca i resultats

Aquest article vol donar a conèixer el procés seguit i els resultats més rellevants de la investigació entorn de les competències que ha de posseir el/la professor/ a a Europa. Per tal d’obtenir la informació sobre el professorat de la nostra comunitat educativa, es va elaborar una enquesta en la qual es van valorar les percepcions que tenen els professors sobre les competències que haurien de tenir per poder desenvolupar la tasca educativa a l'Europa actual i sobre quines creuen que tenen realment en l'actualitat. És la segona part d'una trilogia d'articles publicats en aquesta revista i suposa el punt de partida per dissenyar un ampli estudi de recerca en el marc del projecte «Competences of professional educators in Europe» del programa Comenius, que tracta quines són les competències docents que hauria de posseir el/la professor/ a a Europa per desenvolupar la seva tasca amb eficàcia

Is stomatal conductance optimized over both time and space in plant crowns? A field test in grapevine (Vitis vinifera)

15 páginas.-- 13 figuras.-- 1 tabla.-- 64 referenciasCrown carbon gain is maximized for a given total water loss if stomatal conductance (gs) varies such that the marginal carbon product of water (∂A/∂E) remains invariant both over time and among leaves in a plant crown, provided the curvature of assimilation rate (A) versus transpiration rate (E) is negative. We tested this prediction across distinct crown positions in situ for the first time by parameterizing a biophysical model across 14 positions in four grapevine crowns (Vitis vinifera), computing optimal patterns of gs and E over a day and comparing these to the observed patterns. Observed water use was higher than optimal for leaves in the crown interior, but lower than optimal in most other positions. Crown carbon gain was 18% lower under measured gs than under optimal gs. Positive curvature occurred in 39.6% of cases due to low boundary layer conductance (gbw), and optimal gs was zero in 11% of cases because ∂A/∂E was below the target value at all gs. Some conclusions changed if we assumed infinite gbw, but optimal and measured E still diverged systematically in time and space. We conclude that the theory's spatial dimension and assumption of positive curvature require further experimental testingThis work was funded by the Spanish Ministry of Science and Innovation (research projects AGL2008-04525-C02-01, AGL2011-30408-C04-01 and AGL2009-11310/AGR).

Experiencia de Implantación de Estrategias de Autoevaluación y Coevaluación en el Grado de Ingeniería Telemática

[ES] En este artículo se presenta una propuesta metodológica aplicada a la asignatura Planificación de redes del tercer curso del Grado de Ingeniería Telemática de la Universidad de las Islas Baleares. Se fundamenta en la utilización de técnicas de autoevaluación y coevaluación (evaluación entre iguales) con el objetivo de mantener a los alumnos continuamente informados sobre su proceso de aprendizaje, estimulando la cooperación entre ellos y su interacción con el profesor. Esta metodología consigue además mejorar la capacidad de formular críticas constructivas respecto del trabajo propio y de los compañeros. Los resultados obtenidos ponen de manifiesto la creciente calidad de la tarea de evaluación realizada por los alumnos y evidencian la buena aceptación de esta propuesta metodológica entre ellos.Ramis Bibiloni, J.; Payeras Capellà, MM.; Carrasco Martorell, L.

The 8 and 9 September 2002 flash flood event in France: a model intercomparison

Within the framework of the European Interreg IIIb Medocc program, the HYDROPTIMET project aims at the optimization of the hydrometeorological forecasting tools in the context of intense precipitation within complex topography. Therefore, some meteorological forecast models and hydrological models were tested on four Mediterranean flash-flood events. One of them occured in France where the South-eastern ridge of the French “Massif Central”, the Gard region, experienced a devastating flood on 8 and 9 September 2002. 24 people were killed during this event and the economic damage was estimated at 1.2 billion euros. To built the next generation of the hydrometeorological forecasting chain that will be able to capture such localized and fast events and the resulting discharges, the forecasted rain fields might be improved to be relevant for hydrological purposes. In such context, this paper presents the results of the evaluation methodology proposed by Yates et al. (2005) that highlights the relevant hydrological scales of a simulated rain field. Simulated rain fields of 7 meteorological model runs concerning with the French event are therefore evaluated for different accumulation times. The dynamics of these models are either based on non-hydrostatic or hydrostatic equation systems. Moreover, these models were run under different configurations (resolution, initial conditions). The classical score analysis and the areal evaluation of the simulated rain fields are then performed in order to put forward the main simulation characteristics that improve the quantitative precipitation forecast. The conclusions draw some recommendations on the value of the quantitative precipitation forecasts and way to use it for quantitative discharge forecasts within mountainous areas

Pharmacological properties of bergapten: mechanistic and therapeutic aspects

Bergapten (BP) or 5-methoxypsoralen (5-MOP) is a furocoumarin compound mainly found in bergamot essential oil but also in other citrus essential oils and grapefruit juice. This compound presents antibacterial, anti-inflammatory, hypolipemic, and anticancer effects and is successfully used as a photosensitizing agent. The present review focuses on the research evidence related to the therapeutic properties of bergapten collected in recent years. Many preclinical and in vitro studies have been evidenced the therapeutic action of BP; however, few clinical trials have been carried out to evaluate its efficacy. These clinical trials with BP are mainly focused on patients suffering from skin disorders such as psoriasis or vitiligo. In these trials, the administration of BP (oral or topical) combined with UV irradiation induces relevant lesion clearance rates. In addition beneficial effects of bergamot extract were also observed in patients with altered serum lipid profiles and in people with nonalcoholic fatty liver. On the contrary, there are no clinical trials that investigate the possible effects on cancer. Although the bioavailability of BP is lower than that of its 8-methoxypsoralen (8-MOP) isomer, it has fewer side effects allowing higher concentrations to be administered. In conclusion, although the use of BP has therapeutic applications on skin disorders as a sensitizing agent and as components of bergamot extract as hypolipemic therapy, more trials are necessary to define the doses and treatment guidelines and its usefulness against other pathologies such as cancer or bacterial infections.info:eu-repo/semantics/publishedVersio
