Data Transmission and Thermo-Optic Tuning Performance of Dielectric-Loaded Plasmonic Structures Hetero-Integrated on a Silicon Chip
2012
We demonstrate experimental evidence of the data capture and the low-energy thermo-optic tuning credentials of dielectric-loaded plasmonic structures integrated on a silicon chip. We show 7-nm thermo-optical tuning of a plasmonic racetrack-resonator with less than 3.3 mW required electrical power and verify error-free 10-Gb/s transmission through a 60-mu m-long dielectric-loaded plasmonic waveguide. We demonstrate experimental evidence of the data capture and the low-energy thermo-optic tuning credentials of dielectric-loaded plasmonic structures integrated on a silicon chip. We show 7-nm thermo-optical tuning of a plasmonic racetrack-resonator with less than 3.3 mW required electrical powe…
COEDU-IN Project: an inclusive co-educational project for teaching computational thinking and digital skills at early ages
2021
Learning to program is the new literacy of the 21st century. Computational thinking, closely related to programming, requires thinking and solving problems with different levels of abstraction and is independent of hardware devices. The early childhood education stage provides teachers with the opportunity to lay the foundations for a comprehensive quality education using innovative tools and technologies. Educational robotics in early childhood education becomes a tool that facilitates the acquisition of knowledge to children, playfully, based on the principles of interactivity, social interrelationships, collaborative work, creativity, constructivist and constructionist learning, and a st…

Detection of behavioural patterns in Olympic male taekwondo athletes
2017
The relationship between athletes’ behaviours is relevant for developing defensive and offensive strategies. Traditionally, sequential analysis has been conducted to assess relationships between two behaviours (one considered as focal and the other as conditioned). The aim of the study was to examine Olympic taekwondo athletes’ behavioural patterns by conducting sequential analyses of tactical actions in bouts. Seventy-five male matches of the London Olympic Games in 2012 were studied to analyse tactical actions: attack (direct and indirect), counterattack (anticipatory, simultaneous and posterior), defensive (cuts, blocks and dodges), and opening actions. A sequential analysis of 2 lags (i…
Uso de medicamentos associados ao risco de quedas em idosos não institucionalizados
2018
RESUMEN Objetivo: Determinar qué número de medicamentos consumidos diariamente es influyente en el riesgo de caídas en ancianos no institucionalizados y con historial de caídas en el último año. Método: Estudio descriptivo mediante muestreo aleatorio con la utilización de los siguientes instrumentos de medida: cuestionario de la OMS para el estudio de caídas en el anciano, escala de marcha y escala depresión geriátrica y escala de marcha y equilibrio. El análisis univariante, bivariante con prueba no paramétrica de Chi-cuadrado y regresión logística binaria se ellevó a cabo con el programa estadístico SPSS versión 21.0. Resultados: Participaron del estudio 213 personas. El consumo ≥ a 4 med…
Analysis of Teaching Personal and Social Responsibility model-based programmes applied in USA and Spain
2013
Caballero-Blanco P, Delgado-Noguera, MA, Escarti-Carbonell, A. Analysis of Teaching Personal and Social Responsibility model-based programmes applied in USA and Spain. J. Hum. Sport Exerc. Vol. 8, No. 2, pp. 427-441, 2013. Over the last three decades, several studies have applied Hellison’s Teaching Personal and Social Responsibility (TPSR) model; most of them have generated strong empirical evidences that support that theoretical framework. TPSR is a programme for positive youth development through physical activity. This article compares the different studies that have implemented the TPSR model in the United States and Spain. This paper reviews those researches by analysing their key fea…
Validação de um questionário de satisfação sobre a formação prática de estudantes de enfermagem
2019
Objetivo: validar un instrumento para valorar la formación práctica y la satisfacción con las asignaturas de Practicum de los estudiantes de Enfermería. Método: estudio observacional, descriptivo, transversal (curso 2014-2015). Validación de un cuestionario autoadministrado y anónimo (17 ítems) de Satisfacción sobre el Practicum en Estudiantes de Enfermería, elaborado por consenso de ocho expertos en formación práctica (en tres sesiones de grupo nominal). Se realizó análisis factorial y confirmatorio, estimándose la consistencia interna para determinar su validez. Se calculó la satisfacción de los estudiantes en cada asignatura y en su totalidad.
