Within the framework of numerical modelling and multi-objective control of partial differential equations, in this work we deal with the problem of determining the optimal location of a new industrial plant. We take into account both economic and ecological objectives, and we look not only for the optimal location of the plant but also for the optimal management of its emissions rate. In order to do this, we introduce a mathematical model (a system of nonlinear parabolic partial differential equations) for the numerical simulation of air pollution. Based on this model, we formulate the problem in the field of multi-objective optimal control from a cooperative viewpoint, recalling the standard concept of Pareto-optimal solution, and pointing out the usefulness of Pareto-optimal frontier in the decision making process. Finally, a numerical algorithm – based on a characteristics/Galerkin discretization of the adjoint model – is proposed, and some numerical results for a hypothetical situation in the region of Galicia (NW Spain) are presented. 相似文献

Most universities use Information Systems (IS) to perform their daily administrative activities (student enrollment, data
files, accountancy, etc.), and an integrated Learning Management System (LMS) to support teaching and learning. However, although
a lot of effort has been put into deploying these computerized systems, the data that they provide are not fully exploited
from an educational perspective. In this paper we describe a case in which these data have been used to identify relevant
relations between the general use of the LMS, the existence of teaching innovation programs and the quality of education.
The method used can be easily generalized and employed in other different contexts, to derive meaningful information on the
impact that some variables may have over others. 相似文献

ABSTRACT The aim of this article is to examine how EU lifelong learning policies are trying to reach the vulnerable by looking at what measures against social exclusion they offer and how equitable these measures are. It is a qualitative study that focuses on policy documents that form the European Union’s legal and political frameworks of reference in the lifelong learning area since 1992. The document analysis has been complemented by semi-structured interviews with EU lifelong learning experts. The findings show that early school leavers and migrants are the main target groups in the policies, leaving many other groups at risk of being excluded from learning opportunities. There is not enough attention to measures addressing wider social phenomena. There is also an overemphasis on basic skills which are understood in a very narrow way as literacy and numeracy when referring to the vulnerable. We argue that a greater variety of measures as well as better targeted measures are needed to address the multiple and complex needs of the vulnerable. Such measures would allow a broader understanding of lifelong learning where those that are hardest to reach are offered learning opportunities independent of their personal and social circumstances 相似文献

ResumenLa «hipótesis del juego» («Game hipothesis»), propuesta por Watson en 1972, establece que la percepción de relaciones contingentes entre acciones y estímulos ambientales es, con independencia de la naturaleza de tales estímulos, un determinante poderoso del desarrollo social del bebé. Se investiga la posible influencia de la naturaleza de los estímulos contingentes mediante el uso de estímulos «sociales» (emisiones lingüísticas) y «no sociales» (música) en una situación de percepción de contingencias, que se estableció para 6 bebés, con una edad media de 3 meses y 2 días. Los resultados demuestran que existen diferencias entre los estímulos sociales y no-sociales tanto en lo referente a los patrones de adquisición de las «operantes» o «respuestas circulares» ante las contingencias, como en las respuestas emocionales que acompañaban a los procesos de adquisición y extinción. Estas diferencias sugieren la necesidad de reconocer la importancia de la naturaleza de los estímulos contingentes en la interpretación del papel social de los procesos de percepción de contingencias. 相似文献

This article examines the legal instruments and educational politics affecting deaf persons' educational rights in Spain. We present a historical view of deaf education in Spain before and after the Congress of Milan (1880) and then introduce educational legislation and practices in recent decades. At present, Spanish legislation is moving toward recognition of sign languages and the suitability of bilingual education for deaf students at all educational levels. This is a consequence of taking into account the low academic achievement of two generations of deaf students educated in a monolingual model. Bilingual projects are now run throughout Spain. We emphasize that efforts must be made in the legal sphere to regulate the way in which professionals who know sign language and Deaf culture-teachers, interpreters, deaf adult models-are incorporated in bilingual deaf schools. 相似文献

This article studies the foundations of laic moral education in Spain. Some aspects of laic moral education can also be found in other nations, including the emergence of the laic man or the need for an educating State; other aspects of laic moral education, however, are peculiar to the Spanish case, such as the influence of Krausoinstitutionism and the programmes of 1931 Republicanism. This analysis of laic moral education centres on the bipolarity of traditionalism/liberalism. The article takes 1857 as its starting point, a date that is significant for the birth of laic morality and the Spanish education system. The article’s end point is 1936, on the threshold of the Civil War. This bipolarity of traditional/liberal is in combination, on the one hand, with the demands of Krausoinstitutionism for an independent morality and neutrality in instruction as tools for the attainment of a moral ideal of preparing men and, on the other hand, the Republican vindication of an autonomous morality and school laicism as key to the preparation of citizens, as well as with the demand for a civil morality fostered by an educating State. 相似文献

AbstractThis research has two main aims: a) the study of Spanish teachers’ training and attitudes towards sex education, as well as the delivery of this subject in classrooms, while also exploring the existence of differences according to personal and professional characteristics; and b) to examine the association between teachers’ training and attitudes, and the extent to which these variables predict the delivery of sex education. A total of 3,695 Infant, Primary, Secondary and High school teachers (66.1% women, 33.9% men) throughout the country completed a voluntary online questionnaire that inquired about their training and attitudes towards sex education, their delivery or non-delivery of this subject in classrooms, and other personal and professional characteristics. Analyses indicate that participants show positive attitudes towards sex education, but that 43.3% are not trained in this issue, and 48.6% do not teach it at school. Some significant differences by sex, educational stage and type of school have been found. In addition, trained teachers show more positive attitudes to sex education. Finally, having more positive attitudes and, to a lesser extent, having prior training, positively predicts the delivery of sex education. These results highlight the importance of reviewing and improving teachers’ training on sexuality and sex education, with particular emphasis on attitudinal contents. 相似文献
