Generated emotions by various types of games in physical education
El objetivo del presente estudio ha sido ahondar en el conocimiento de las
emociones generadas a través de la práctica de diversos tipos de juegos,
mediante la puesta en práctica de una propuesta diseñada a tal efecto. Más
concretamente se ha tratado de conocer en qué medida, los juegos cooperativos
y de oposición permiten el desarrollo emocional del alumnado en comparación
con los juegos populares cooperativos y de oposición. Los participantes han sido
un total de 50 alumnos y alumnas de sexto curso de Educación Primaria. El
instrumento empleado ha sido el cuestionario sobre las percepciones socioemocionales
de Gil-Madrona y Martínez (2016). Los resultados indican una gran
similitud entre la utilización de los juegos cooperativos y juegos populares
cooperativos. No obstante, los juegos populares de oposición producen mayores
emociones positivas en el alumnado respecto a los juegos de oposición. El
porcentaje de alumnado que se decanta por las emociones plancenteras es
manifiestamente superior al de aquellos que se decantan por las displacenteras.
Finalmente, se concluye que la propuesta utilizada es eficaz para producir
emociones en los cuatro dominios de acción motriz objeto de estudioThe aim of this research has been to know which are the generated emotions
through the practice of diverse kinds of games, through a proposal. Specifically,
it is have been tried to know how cooperative and opposition games allow for
the emotional development of the students with respect to traditional
cooperative games and traditional opposition games. A total of 50 children of 6th
grade took part in this work. The instrument used was the Gil-Madrona and
Martinez's questionnaire (2016) about socio-emotional perceptions. The results
indicate a similarity between using cooperative and traditional cooperative
games. However, traditional opposition games produce greater positive
emotions in students with respect to opposition games. Finally, it is concluded
that the approach used is effective to produce emotions in the four motor
domains studie
Uso de X-Road para implementar datos abiertos en sistemas eléctricos y promover la integración con estrategias de ciudad inteligente y gobierno abierto
The electrical industry is undergoing a deep digital transformation towards the consolidation of smart grids, which requires a high demand of data and information systems involved in the processes. Open data initiatives, which have been focused on open governance to a great extent, generate positive impacts on society and the economy in terms of easy access to public resources, agility, and transparency. These initiatives can also be adopted in the electrical industry (i.e., power, electrical, and energy systems) for customer engagement, collaboration with other industries, and reaching consensus. This study proposes the implementation of an open data solution for the electrical industry through the deployment of a data hub that offers digital services for smart city applications and the integration of the X-Road system to improve the security and interoperability of open data. This initiative aims to promote a wider adoption of open data in the electrical industry and prepare the latter for fully connected and collaborative digital ecosystems in smart cities, industries, and governments. This study also proposes an open data architecture for the interoperability of the electrical industry with other digital industries (through a Smart City Hub and the adoption of 5G technology), and it reports some relevant results and major findings in this regard. This paper highlights the benefits of promoting open data and technological strategies for digitized electrical systems while considering humans an essential factor. Finally, it discusses the pros and cons of the integration of X-Road with the electrical industry under the concept of smart grids for data exchange and potential applications.La industria eléctrica está experimentando una profunda transformación digital hacia la consolidación de redes inteligentes, que necesita una alta demanda de datos y sistemas de información involucrados en los procesos.

Estas iniciativas también se pueden adoptar en la industria eléctrica para sistemas de potencia, eléctricos y de energía para su uso en la participación de los clientes, la colaboración y la mejora de consenso en industrias. Esta investigación propone la implementación de una solución de datos abiertos para la industria eléctrica mediante el despliegue de un Hub que ofrece servicios digitales para aplicaciones de ciudad inteligente y la integración del sistema X-Road para mejorar la seguridad e interoperabilidad de los datos abiertos. Esta iniciativa pretende una adopción más amplia de datos abiertos en la industria eléctrica y su preparación para ecosistemas digitales totalmente conectados y colaborativos en ciudades inteligentes, industrias y gobierno. Se muestran algunos resultados relevantes y hallazgos importantes de este trabajo acerca de una arquitectura de datos abiertos para la interoperabilidad del sector eléctrico con otras industrias digitales a través de un Smart City Hub y la adopción tecnológica de 5G, exponiendo los beneficios de promover los datos abiertos y estrategias tecnológicas para sistemas eléctricos digitalizados mientras se considera el humano como factor esencial. Se discuten los pros y los contras de la integración de X-Road con la industria eléctrica dentro del concepto de redes inteligentes para el intercambio de datos y aplicaciones potenciales
A scale to measure educators’ musical skills in early childhood education
Evaluating skills of students training to become teachers in early childhood education (ECE) is a key measure to improve their training and, subsequently, to bring about improvements in the way they train their pupils. No research literature specifically describing a scale designed to measure educators’ musical skills at the ECE level has been previously published. In view of this lack, we carried out the customary procedures for designing and validating a psychological measurement scale: on the basis of a sample of university students (n = 209), we created a valid, reliable tool that allows researchers to evaluate and quantify how teacher trainees perceive their own musical skills. By applying EFA, Parallel Analysis, and CFA, we observed the emergence of four differentiated categories distributed along 25 items in the questionnaire''s final version. To improve and refine this tool, further research and study replication in a series of different educational contexts would be required. © 2021 The Author(s
Implications of instructional strategies in sport teaching: a nonlinear pedagogy-based approach
In this article, we have tried to establish the practical implications of instructional strategies in sport teaching. Firstly, we have highlighted the importance of the Teaching Game for Understanding as a teaching model that is fundamentally based on the use of modified games, whose purpose is for students to learn the tactical aspects of a certain sport, by way of modified versions of the real game. Later on, we have gone further into depth into a new way of understanding the teaching-learning process in sport, non-Linear Pedagogy, which is based on manipulating the relevant determining factors (task, environment and individual) to increase information sources and thus be able to guide students towards obtaining their objectives. Within non-linear pedagogy, verbal instruction (e.g., questioning) is considered to be a determining factor that attempts to channel the search for tactical solutions within a learning environment. Finally, we end the article with a section that refers to practical applications, where we purport to give a series of guidelines on how to implement questioning as a didactical resource whose aim is to improve students’ tactical action capacity
Wheel shape optimization approaches to reduce railway rolling noise
[EN] A wheel shape optimization of a railway wheel cross section by means of Genetic Algorithms (GAs) is presented with the aim of minimizing rolling noise radiation. Two different approaches have been implemented with this purpose, one centred on direct Sound poWer Level (SWL) minimization, calculated using TWINS
methodology, and another one emphasizing computational efficiency, focused on natural frequencies maximization. Numerical simulations are carried out with a Finite Element Method (FEM) model using general axisymmetric elements. The design space is defined by a geometric parametrization of the wheel cross section with four parameters: wheel radius, a web thickness factor, fillet radius and web offset. For all wheel candidates a high-cycle fatigue analysis has been performed according to actual standards, in order to assure structural feasibility. Rolling noise reductions have been achieved, with a decrease of up to 5 dB(A) when considering the wheel component. Response surfaces have been also computed to study the dependency of the objective functions on the geometric parameters and to test the adequacy of the optimization algorithm
applied.This study was financially supported by Ministerio de Ciencia, Innovacion y Universidades - Agencia Estatal de Investigacion, European Regional Development Fund (project TRA2017-84701-R), and Conselleria d'Educacio, Investigacio, Cultura i Esport (Generalitat Valenciana, project Prometeo/2016/007).García-Andrés, FX.; Gutiérrez-Gil, J.; Martínez Casas, J.; Denia, FD.

Object-Oriented Business Solutions
This report summarises the presentations, discussions, and main results of the ECOOP’01 Workshop on Object-Oriented Business Solutions (WOOBS).
It was not a pure scientific meeting, but a mixed gathering where people from the industry and the academia met to exchange ideas, experiences and build a network of relationships with others committed to the emergence of object-oriented business solutions. WOOBS had an invited talk on quality of service, twelve presentations and lively discussions during and after them. The main conclusions were on the importance of Multi-Organisational Web-Based Systems in today’s e-commerce world, which justifies the study of a new multidisciplinary paradigm called Web-Oriented Programming
Universal Conductance Distributions in the Crossover between Diffusive and Localization Regimes
The full distribution of the conductance in quasi-one-dimensional
wires with rough surfaces is analyzed from the diffusive to the localization
regime. In the crossover region, where the statistics is dominated by only one
or two eigenchannels, the numerically obtained P(G) is found to be independent
of the details of the system with the average conductance as the only
scaling parameter. For < e^2/h, P(G) is given by an essentially
``one-sided'' log-normal distribution. In contrast, for e^2/h <= 2e^2/h,
the shape of P(G) remarkable agrees with those predicted by random matrix
theory for two fluctuating transmission eigenchannels.Comment: Accepted for publication in Phys. Rev. Let
