ResumenEn la perspectiva metodológica de la Psicologia Ecológica y en su consideración de la clase como unidad ambiental, el presente artículo hace referenda a una investigación sobre los diferentes modos de ocupación/interacción de dos grupos de parvulario con características diferenáadas (procedencia social y cultural, ubicación del edificio, actitud pedagógica…) con los equipamientos que conforman en entorno-clase.La ocupación viene definida por (a) el número de desplazamientos que realiza cada alumno, (b) los objetos a los que se dirige y (c) la significación que va unida a cada desplazamiento.Las conclusiones derivadas de los resultados obtenidos evidencian diferencias entre los dos grupos en relación (1) con el modo de organización de la clase en función de la actitud pedagógica del profesor (2) con el papel que adquiere la maestra por la referencia del 45% de las interacciones que se originan en cada grupo. 相似文献

Is Cross-Language answer finding harder than Monolingual answer finding for users? In this paper we provide initial quantitative and qualitative evidence to answer this question. 相似文献

School leaders can ally with other educational stakeholders to encourage undocumented student persistence in Pk-12 schools. We explore (1) how school leaders create systems of support for undocumented and newly arrived immigrant students, and (2) how school leaders interpret and implement policies or school structures that affect student educational access. Border crossing theory guides our examination of how school leaders traverse and transgress borders that can impede students' education. This embedded case study included interviews with nine administrators working on the US-México border. The study finds that leaders expected to make a difference in students' lives by focusing on relationships and programming, committing to equity, and resisting deficit thinking about students and their families. 相似文献

Purpose: Several studies have demonstrated that physiological variables predict cycling endurance performance. However, it is still unclear whether the predictors will change over different performance durations. The aim of this study was to assess the correlations between physiological variables and cycling time trials with different durations. Methods: Twenty trained male cyclists (maximal oxygen uptake [VO2max] = 60.5 ± 5.6 mL/kg/min) performed 4 separate experimental trials during a 2-week period. Cyclists initially completed an incremental exercise test until volitional exhaustion followed by 3 maximal cycling time trials on separate days. Each time trial consisted of 3 different durations: 5 min, 20 min, and 60 min performed in a randomized order. Results: The main results showed that the physiological measures strongly correlated with long cycling performances rather than short and medium time trials. The time-trial mean power output was moderately high to highly correlated with peak power output and VO2max (r = .61–.87, r = .72–.89, respectively), and was moderately to highly correlated with the lactate threshold Dmax method and second ventilatory threshold (r = .52–.75, r = .55–.82, respectively). Conclusions: Therefore, trained cyclists should develop maximal aerobic power irrespective of the duration of time trial, as well as enhancements in metabolic thresholds for long-duration time trials. 相似文献

Contingent Valuation and Semiparametric Methods: A Case Study of the National Museum of Sculpture in Valladolid, Spain 总被引:1,自引:0,他引:1

Research on cultural economics is very interested in the economic valuation of non-market goods, particularly in the field ofcultural heritage where contingent valuation techniques are currently being used with both parametric and non-parametric statistical methods to estimate the willingness to pay for cultural goods. In the literature analysed, the number of studies using semiparametric methods, however, is very limited. Our analysis is intended to help fill this gap by offering a parametric, non-parametric and semiparametric economic valuation of the National Museum of Sculpture (Museo Nacional de Escultura), located in Valladolid,Spain. In addition, we also gain insight on a controversial issue affecting most European museums, particularly those located in Latin countries: the role voluntary donations might play in the funding of public museums. 相似文献

The costs for deterioration and soiling of different materials due to air pollution are huge and the damage to culture targets endangers seriously the rich European cultural heritage. Within the sixth Framework Programme of the EU, the overall aim of the CULT-STRAT project has been to assess and predict the effects of different pollutants on materials and objects of cultural heritage in a multipollutant scenario and to identify indicators and thresholds levels of pollutants. In particular, the present paper reports one of the studies carried out in the CULT-STRAT project at city level and focused on the town of Madrid (Spain). Different maps are shown for the past, present and possible future scenarios: inventory of stock of cultural heritage for each selected material, concentration of selected pollutants (SO2, NO2, O3 and PM10), corrosion (cast bronze) and recession (Portland limestone), exceedance of tolerable degradation thresholds for each material and corrosion-cultural heritage overlapped maps. The model and the methodology developed could be useful if apply it to towns, regions or countries in order to quantify the percentage of Cultural Heritage at risk or to quantify the percentage of the area where corrosion/recession exceeds the established tolerable levels. 相似文献
