Preservice teachers implementing a nonlinear physical education pedagogy
2019
Background\ud In recent years, there has been considerable interest in the evolution of physical education teaching practice from a traditional teacher-centred approach to a student-centred approach. Consequently, research has focused on questions about the changing conceptions of the teaching and learning process, that is, from how ‘we’ teach to how ‘they’ learn. A contemporary theoretical model of the teaching and learning process could underpin learning design and delivery adopted in physical education. The constraints-led approach (CLA) is a viable alternative as its practice design and delivery is grounded in the contemporary motor learning theory of ecological dynamics within a nonlin…
Comparison of Interactive Teaching in Online and Offline Platforms among Dental Undergraduates
2022
In recent years, the educational system has focused more on the holistic development of an individual. Modern technology has changed the educational environment to provide students with better academic opportunities. Along with the education system, teaching techniques and learning tools have also changed with digital evolution. This research was undertaken to assess the academic performance of interactive teaching methods in offline and online platforms in Periodontics among BDS undergraduates at a dental college in India. This prospective study was conducted among 49 students: Group I (n = 24, online class through Zoom) and Group II (n = 25, offline classes). The subject was divided into …
Exploring the experiences concerning leadership communication in online gaming groups
2009
This paper looks at leadership communication in the context of multiplayer computer games and the groups that operate within them. In multiplayer games promoting teamwork and long-term cooperation, issues of management and leadership are prevalent. The paper explores the experiences that members of multiplayer communities have towards leadership communication in multiplayer games by looking at one specific case of organized team play within the framework of a turn-based online strategy game. The data utilized in this study consists of themed player interviews conducted via e-mail. The analysis proposes three central dimensions that emerged from the data. These were labeled: 1) the leader as…
Leadership in an online multiplayer strategy game: case – Illuria
2011
This paper looks at leadership communication in the context of online multiplayer games and the groups that operate within them. In multiplayer games promoting teamwork and long-term cooperation, issues of management and leadership are prevalent. The study explores the experiences that members of multiplayer communities have towards leadership in multiplayer games by looking at one specific case of organised team play within the framework of a turn-based online strategy game. The data utilised in this study consist of themed player interviews conducted via e-mail. The analysis proposes three central dimensions that emerged from the data. These were labelled: (1) the leader as primus motor, …
Effects of Group Formation on Student Satisfaction and Performance: A Field Experiment
2021
This study analyzes the relation of group formation on outcomes of a 4-week online course for prospective students. Group formation was experimentally manipulated based on predefined criteria, personality traits conscientiousness and extraversion. As research questions, groups were considered advantageous if they were formed (a) heterogeneously in extraversion, and (b) homogeneously in conscientiousness. As a result, no uniform outcome was identified. Most variance could be explained on group level, but no significant main effect for experimental grouping was found. Significant interaction between both main effects hint that the results do not provide final answers, but guidance for furthe…
High-precision mass measurement of $^{168}$Yb for verification of nonlinear isotope shift
2020
The absolute mass value of $^{168}$Yb has been directly determined with the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. A more precise value of the mass of $^{168}$Yb is needed to extract possible signatures of beyond standard model physics from high-precision isotope shift measurements of Yb atomic transition frequencies. The measured mass-excess value, ME($^{168}$Yb) = $-$61579.846(94) keV, is 12 times more precise and deviates from the Atomic Mass Evaluation 2016 value by 1.7$\sigma$. The impact on precision isotope shift studies of the stable Yb isotopes is discussed.
A new tool to create on-line examinations. Integration into Aula Virtual.
2009
Actualmente, la Universitat de València utiliza un Sistema de Gestión del Aprendizaje (en ingles Learning Management System LMS), como apoyo al proceso de enseñanza-aprendizaje. Este LMS incluye una herramienta que permite a los profesores crear exámenes online. Sin embargo, la interfaz de usuario que provee la plataforma no presenta un entorno amigable. Para mejorar la usabilidad del modulo, hemos desarrollado un programa informático que simplifica el proceso. Partiendo de un programa open source denominado QAED, desarrollado en la Universitat Pompeu Fabra, lo hemos extendido para permitir a los profesores crear exámenes offline. Después, pueden importarse fácilmente al Aula Virtual.
Learning non-linear time-scales with kernel -filters
2009
A family of kernel methods, based on the @c-filter structure, is presented for non-linear system identification and time series prediction. The kernel trick allows us to develop the natural non-linear extension of the (linear) support vector machine (SVM) @c-filter [G. Camps-Valls, M. Martinez-Ramon, J.L. Rojo-Alvarez, E. Soria-Olivas, Robust @c-filter using support vector machines, Neurocomput. J. 62(12) (2004) 493-499.], but this approach yields a rigid system model without non-linear cross relation between time-scales. Several functional analysis properties allow us to develop a full, principled family of kernel @c-filters. The improved performance in several application examples suggest…
Análisis de métodos de validación cruzada para la obtención robusta de parámetros biofísicos
2015
[EN] Non-parametric regression methods are powerful statistical methods to retrieve biophysical parameters from remote sensing measurements. However, their performance can be affected by what has been presented during the training phase. To ensure robust retrievals, various cross-validation sub-sampling methods are often used, which allow to evaluate the model with subsets of the field dataset. Here, two types of cross-validation techniques were analyzed in the development of non-parametric regression models: hold-out and k-fold. Selected non-parametric linear regression methods were least squares Linear Regression (LR) and Partial Least Squares Regression (PLSR), and nonlinear methods were…
Alcohol, tobacco and drug use among young people: a study of recent Spanish teen series (2015-2021)
2022
El presente trabajo analiza la representación de los adolescentes y el consumo de alcohol, tabaco y otras drogas en las teen series españolas recientes (2015-2021) creadas para la televisión convencional y las plataformas de video on demand (VOD). Resulta esencial estudiar el discurso que la ficción televisiva ofrece sobre el consumo de sustancias en la adolescencia para conocer los modelos identitarios y las representaciones sociales que se presentan, puesto que las personas jóvenes suelen recurrir a las series de televisión como fuente de información sobre temas en los que son más inexpertos, como pueden ser algunas cuestiones y problemáticas específicas en torno al consumo de sustancias …
