La educación bilingüe y el aprendizaje de una segunda lengua: sus características y principios fundamentales

Resumen

Dada la importancia que están adquiriendo en nuestro país y en el mundo entero las investigaciones sobre educación bilingüe y enseñanza de una L2, en este articulo, que sirve de introducción para el tema monográfico sobre la segunda lengua en la escuela, se pretende, en primer lugar, ofrecer una revisión de los términos fundamentales relacionados con estos temas, intentando precisar la significación de algunos de ellos para evitar ciertas confusiones que se producen con frecuencia.

En segundo lugar, se hace referencia a las características del sujeto, del ambiente y del programa que es necesario tomar en consideración para elaborar y evaluar un programa de educación bilingüe y de enseñanza de una L2.

En tercer lugar, se insiste en la importancia de realizar una evaluación correcta y completa de estos programas, para lo cual han de tenerse en cuenta todos los factores analizados previamente.     

Accelerated matrix recovery via random projection based on inexact augmented Lagrange multiplier method

In this paper, a unified matrix recovery model was proposed for diverse corrupted matrices. Resulting from the separable structure of the proposed model, the convex optimization problem can be solved efficiently by adopting an inexact augmented Lagrange multiplier (IALM) method. Additionally, a random projection accelerated technique (IALM+RP) was adopted to improve the success rate. From the preliminary numerical comparisons, it was indicated that for the standard robust principal component analysis (PCA) problem, IALM+RP was at least two to six times faster than IALM with an insignificant reduction in accuracy; and for the outlier pursuit (OP) problem, IALM+RP was at least 6.9 times faster, even up to 8.3 times faster when the size of matrix was 2 000×2 000.

Home advantage in Greek football

Abstract

Home advantage as it relates to team performance at football was examined in Superleague Greece using nine seasons of game-by-game performance data, a total of 2160 matches. After adjusting for team ability and annual fluctuations in home advantage, there were significant differences between teams. Previous findings regarding the role of territorial protection were strengthened by the fact that home advantage was above average for the team from Xanthi (P =0.015), while lower for teams from the capital city Athens (P =0.008). There were differences between home and away teams in the incidence of most of the 13 within-game match variables, but associated effect sizes were only moderate. In contrast, outcome ratios derived from these variables, and measuring shot success, had negligible effect sizes. This supported a previous finding that home and away teams differed in the incidence of on-the-ball behaviours, but not in their outcomes. By far the most important predictor of home advantage, as measured by goal difference, was the difference between home and away teams in terms of kicked shots from inside the penalty area. Other types of shots had little effect on the final score. The absence of a running track between spectators and the playing field was also a significant predictor of goal difference, worth an average of 0.102 goals per game to the home team. Travel distance did not affect home advantage.

基于梯形模糊语言变量的多属性决策方法

研究了决策者的偏好信息（属性值）为梯形模糊语言变量（TFLV）的模糊语言多属性决策问题．定义了2个梯形模糊语言变量比较的可能度公式并研究了它的一些基本性质,给出了基于可能度公式的梯形模糊语言变量多属性决策的方案排序方法．这种方法通过对决策信息进行TFLWA算子加权集结,并通过比较梯形模糊语言变量的可能度得到所有方案的排序结果．在不损失模糊语言信息的条件下,该方法计算过程简单,决策结果合理且有效．最后,通过一个实例说明了该方法的操作过程．
