Caracterización del discurso pedagógico del docente de Educación Física e identificación de los actos de habla que estimulan la creatividad motriz

El presente artículo, es un avance del estudio que describe los actos de habla que predominan en el discurso de los profesores de Educación Física, y cuáles de éstos estimulan la creatividad motriz de los estudiantes. El estudio se basa en el análisis del discurso de 14 docentes en 10 colegios públicos y privados de Bogotá D.C. El discurso de los docentes se grabó durante la observación de 164 sesiones de clase, se trascribió totalmente y se vació en una primera matriz de análisis inductivo. Esta información fue contrastada con la matriz de análisis que contiene cuatro categorías: La dimensión instructiva, la dimensión afectiva, la dimensión motivacional y la dimensión social; cada una de ellas, se describió con sus respectivas sub-categorías. Los resultados iniciales indican la predominancia de la dimensión instructiva, desde la cual se evidencia el dominio de la asignatura por parte del profesor. La dimensión motivacional y afectiva, se caracteriza porque el docente es el mayor factor motivador para el aprendizaje. Por último, la dimensión social en el discurso del docente tiene un sentido humanizador, el cual favorece el desarrollo personal y la participación en comunidad del alumno.The present article is a study in progress which describes speech acts that prevails in the discourse of physical education teachers and which of these teachers stimulate motor creativity. This study is based on the discourse analysis of 14 teachers among 10 public and private schools in Bogota. Teachers' discourse was recorded during an observation of 164 class sessions; it was transcribed entirely and placed in a matrix of inductive analysis. Previous information was contrasted with the analysis matrix which has four categories such as instructive dimension, affective dimension, motivational dimension and social dimension: each dimension was described with their respective sub-categories. Initial findings show predominance of instructive dimension, from which it is evidenced the subject dominance on teacher's behalf. Motivational and affective dimension are featured because the teacher is the highest motivating factor of learning. Finally, social dimension in teacher's discourse has a humanizing meaning; this one is in favour of personal development and participation at student's communit

Smart scheduling for saving energy in grid computing

Energy saving involves two direct benefits: sustainability and cost reduction. Within the field of Informa tion Technology, clusters, grids and data centres represent the hungriest consumers of energy and there fore energy (saving) policies for these infrastructures should be applied in order to maximize their resources. It is proved in this paper that approximately 40% of energy can be saved in a data centre if an adequate policy is applied. Furthermore, a software tool is presented where simulations can be run and results for real scenarios can be obtained.Ministerio de Ciencia e Innovación TIN2009–14378-C02–0

LECOMP: Low Energy COnsumption Mesh Protocol in WSN

LECOMP is a mesh network protocol that is focused on minimizing bat tery consumption of nodes in a Wireless Sensor Network (WSN). This paper is a improvement of a first approach [1] which proposes a method to extend the life time and the reliability in a WSN balancing transmissions saving energy throughout different nodes in order to consume homogeneously nodes’ batteries, and taking into account distances and hops of routes. First, a central node analyzes messages from nodes during a training period to determine new routing rules for each sensor. Second, the server configures the network adding the computed rules to the nodes. Third, central server can reconfigure the network routes when new balance of load is neededMinisterio de Economía y Competitividad TIN2009-14378-C02-01 (ARTEMISA

Software reference architecture for smart environments: Perception

With the increase of intelligent devices, ubiquitous computing is spreading to all scopes of people life. Smart home (or industrial) environments include automation and control devices to save energy, perform tasks, assist and give comfort in order to satisfy specific preferences. This paper focuses on the proposal for Software Reference Architecture for the development of smart applications and their deployment in smart environments. The motivation for this Reference Architecture and its benefits are also explained. The proposal considers three main processes in the software architecture of these applications: perception, reasoning and acting. This paper centres attention on the definition of the Perception process and provides an example for its implementation and subsequent validation of the proposal. The software presented implements the Perception process of a smart environment for a standard office, by retrieving data from the real world and storing it for further reasoning and acting processes. The objectives of this solution include the provision of comfort for the users and the saving of energy in lighting. Through this verification, it is also shown that developments under this proposal produce major benefits within the software life cycle.Ministerio de Economía y Competitividad TIN2009-14378-C02-01 (ARTEMISA)Junta de Andalucía TIC-8052 (Simon
