E-Oral, una herramienta para evaluar la expresión oral y la comprensión auditiva a distancia
2016
E-Oral es la aplicación informática que el Centro de Idiomas (CUID) de la UNED utiliza para evaluar las destrezas orales de los alumnos matriculados en cursos virtuales de idiomas. Esta herramienta permite evaluar de forma asincrónica. No es, sin embargo, una prueba completamente automatizada, puesto que los evaluadores son humanos. Las denominadas tecnologías del habla presentan aún hoy ciertas restricciones que limitan su experimentación en el campo de la evaluación y la certificación lingüística. El artículo es una presentación de la herramienta. Palabras clave: tecnologías del habla, evaluación, expresión oral, comprensión auditiva. E-oral, a tool to assess oral expression and liste…
Impact of the terrestrial reference frame on the determination of the celestial reference frame.
2022
Currently three up-to-date Terrestrial Reference Frames (TRF) are available, the ITRF2014 from IGN, the DTRF2014 from DGFI-TUM, and JTRF2014 from JPL. All use the identical input data of space-geodetic station positions and Earth orientation parameters, but the concept of combining these data is fundamentally different. The IGN approach is based on the combination of technique solutions, while the DGFI is combining the normal equation systems. Both yield in reference epoch coordinates and velocities for a global set of stations. JPL uses a Kalman filter approach, realizing a TRF through weekly time series of geocentric coordinates. As the determination of the CRF is not independent of the T…
Sykepleiestudentenes kliniske praksis – om klinisk læringsmiljø og studenttilfredshet

Nurse practice – clinical learning environment and student satisfaction
 The purpose of this study was to investigate nursing students’ satisfaction with the clinical learning environment during clinical practice. A questionnaire was distributed to nursing students at a university (N=250) in Norway. Student satisfaction, task orientation, pedagogical atmosphere, supervisory relationship, and the premises of nursing on the ward were measured. Of the 250 students invited, 163 (66 %) completed the survey. Nursing students were largely satisfied with their clinical placement experiences, but they were more satisfied with hospital placements than home care placements. Supervision more than …
Special Issue on Computational Intelligence and Nature-Inspired Algorithms for Real-World Data Analytics and Pattern Recognition
2018
This special issue of Algorithms is devoted to the study of Computational Intelligence and Nature-Inspired Algorithms for Real-World Data Analytics and Pattern Recognition. The special issue considered both theoretical contributions able to advance the state-of-the-art in this field and practical applications that describe novel approaches for solving real-world problems.
Resonance in Interacting Induced-Dipole Polarizing Force Fields: Application to Force-Field Derivatives
2009
The Silberstein model of the molecular polarizability of diatomic molecules, generalized by Applequist et al. for polyatomic molecules, is analyzed. The atoms are regarded as isotropically polarizable points located at their nuclei, interacting via the fields of their induced dipoles. The use of additive values for atom polarizabilities gives poor results, in some cases leading to artificial predictions of absorption bands. The molecular polarizability of methane and its derivative are computed. The agreement with experimental mean molecular polarizabilities is within 1–5%. A hypothesis is indispensable for a suitable representation of polarizability derivative.
A new Three Color Marker for TCP flows
2004
In Differentiated Services networks, packets may receive a different treatment according to their Differentiated Services Code Point (DSCP) label. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same TCP flow, with the goal of improving the experienced performance. This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, which relies on three different service classes, provided by the DiffServ network. The scheme provides protection of vulnerable packets in the TCP flows and adaptivity through "probes" packets. The performance have been evaluted in a traffic scenario composed of TCP flows with different …
A NEW TOOL FOR THE STUDY OF RESONANCE IN CHEMICAL EDUCATION
2014
The objective of this study is to present a computer-based project, for which our program POLAR and our version of PAPID were written for the study of the subject of resonance in chemistry. Both algorithms allow a better didactic strategy and methodological adaptation for the study of molecular properties in chemical education. Teachers will find the options of POLAR and PAPID useful for demonstrations. It is still to be explored the methodological application of these computational programs enriching the present teaching techniques. Implementing new algorithms in learning situations is technically simple, but checking their usefulness in teaching practice is extraordinarily complex and req…
Teaching Adaptively for Music - Smart Opportunities Emerging from the Representation of Score Notation
2014
Many developmental approaches have been proposed in literature and are currently in use in order to define music education curricula for young students. In this context, our research aims at describing a computer-based framework for the adaptive teaching of music. A music learning environment can be considered as smart when adaptive technologies are employed in order to improve student performance. Research about effective teaching practice pointed out that adaptive instruction can provide school settings able to foster inclusion and differentiation. Adaptive instruction can be conceptually defined as a set of alternative didactic strategies – either formal or non-formal – within a curricul…
Collaborative leadership as the lens for co-creating an innovation - A curriculum reform in management education
2013
The paper presents collaborative leadership to create a curriculum reform in management education. In our case study, a particular business school wanted to re-modify its curriculum according to turbulence coming, first, outside of the school in terms of increasing complexity in business life and, second, from inside in terms of a large merger. As a consequence, in the co-creation process, a socially-mediated perturbance process started in the school in order to answer the turbulence. According our preliminary results, this kind of process seems to be multilevel and multiphase. It requires new attitudes and a change of the mindset to see management education containing not only knowledge bu…
Development of student leadership skills and identity : a case study at a Finnish university
2017
The modern world is constantly changing and presents new challenges to individuals entering professional and adult life. Many scholars recognize that leadership skills are a crucial tool for solving problems in all areas of society.Leadership is no longer believed to be an inborn trait, but rather something that can be taught and learned. This thesis aims to understand how students at the University of Jyväskylä assess their own leadership skills and their importance. It would also like to discover which activities, organizations, courses and experiences influenced students’ leadership development and how. Ultimately, this thesis would like to highlight opportunities to promote student lead…
