Investigating metaphors of musical involvement : Immersion, flow, interaction and incorporation
2018
The concept of immersion, despite being relatively unknown within music research, presents a potentially productive way for understanding the well acknowledged phenomenon of "being drawn into music". This paper 1) discusses immersion as a metaphor for conceptualizing musical involvement by drawing on the research into video games and virtual reality and 2) aims to clarify the metaphor of immersion by utilizing the concept of image schema to analyze it in relation to alternative metaphors of flow, interaction and incorporation. The theoretical stance of the paper is based on the paradigm of enactive cognitive sciences, which stresses the bodily, constructive and interactive nature of experie…
Muestra de los resultados obtenidos en el constructo metodología de evaluación de los docentes desde el concepto de Cohesión Social
2019
En el presente artículo se examinan los resultados obtenidos en el proyecto SECS-EVALNEC (Sistema Educativo y Cohesión Social: Diseño de un modelo de evaluación de necesidades) donde desde la perspectiva de la cohesión social (CS) analizamos el constructo de metodología de evaluación de los docentes en el nivel de 3º de Educación Secundaria Obligatoria (ESO), en un centro educativo del área metropolitana de Valencia. Desde la CS, se entiende la educación como el mejor instrumento de las políticas sociales para orientar la transformación y la mejora de las personas, los colectivos y la sociedad. A lo largo de esta investigación se estudian los distintos ítems desarrollados en el proyecto SEC…
AX-PET: Concept, proof of principle and first results with phantoms
2010
AX-PET is a novel PET concept based on long crystals axially arranged and orthogonal Wavelength shifter (WLS) strips, both individually readout by Geiger-mode Avalanche Photo Diodes (G-APD). Its design was conceived in order to reduce the parallax error and simultaneously improve spatial resolution and sensitivity. The assessment of the AX-PET concept and potential was carried out through a set of measurements comprising individual module characterizations and scans in coincidence mode of point-like and extended sources. The estimated energy and spatial resolutions from point-like measurements are R FWHM =11.6% (at 511 keV) and 1.7–1.9 mm (FWHM) respectively as measured with point-like sour…
Effect of inter-crystal scatter on estimation methods for random coincidences and subsequent correction.
2008
Random coincidences can contribute substantially to the background in positron emission tomography (PET). Several estimation methods are being used for correcting them. The goal of this study was to investigate the validity of techniques for random coincidence estimation, with various low-energy thresholds (LETs). Simulated singles list-mode data of the MADPET-II small animal PET scanner were used as input. The simulations have been performed using the GATE simulation toolkit. Several sources with different geometries have been employed. We evaluated the number of random events using three methods: delayed window (DW), singles rate (SR) and time histogram fitting (TH). Since the GATE simula…
Writing, Learning And The Development Of Expertise In Higher Education
2001
This chapter combines the issue of writing to learn with recent views of the development of prerequisites of professional expertise during higher education. The knowledge-intensive or symbolicanalytic work characteristic of today's professional jobs challenges educationalists to develop instructional methods that integrate domain-content learning with practising the general skills needed in today’s working life. It is argued here that constructivist and social constructivist views of learning offer promising starting points for developing instruction of this kind. Different traditional and novel fonns of writing are discussed from the viewpoint of these constructivist approaches and experti…
University Students´ Knowledge Construction during Face to Face Collaborative Writing
2014
Collaborative writing combines social processes of writing with cognitive knowledge construction processes, and thus may lead to deeper learning than individual working. This study examined students’ knowledge construction during face-to-face collaborative writing. University students (n = 21) prepared themselves for the collaborative task by reading about developmental theories in a course book and writing individual summaries of them. In small groups, the students discussed each others’ summaries and wrote a joint essay on one of the theories. The data comprise the students’ individual summaries (n = 21), the students’ discussions during the essay writing (8177 speech turns), and the stud…
Aggregation and sedimentation of active Brownian particles at constant affinity.
2019
We study the motility-induced phase separation of active particles driven through the interconversion of two chemical species controlled by ideal reservoirs (chemiostats). As a consequence, the propulsion speed is non-constant and depends on the actual inter-particle forces, enhancing the positive feedback between increased density and reduced motility that is responsible for the observed inhomogeneous density. For hard discs, we find that this effect is negligible and that the phase separation is controlled by the average propulsion speed. For soft particles and large propulsion speeds, however, we predict an observable impact on the collective behavior. We briefly comment on the reentrant…
Sources and Boundaries of Institutional and Linguistic Normativity. Towards a Critical Social Ontology.
2013
Since Hegel and until speech acts theory and contemporary social ontology it came to full development the idea that most of reasons, duties, rights, entitlements, have to do, against Kant, with our participation to social, linguistic and institutional practices of the lifeform to which we belong rather than or more than with our dealing with “substantive moral principles”. But if we accept, with Hegel, that every individual rational determination of the will is justified as such only as a part of our collective Sittlichkheit (Hegel, 1967, cf. Di Lorenzo Ajello, 2009); if we accept from speech acts theory that there are commitments, rights and entitlements specific to every type of speech ac…
La construction territoriale d'une offre périscolaire dans le département de la Côte d'Or : les familles, les collectivités et la réforme
2017
Cette enquête porte sur la mise en ouvre de la réforme de l'articulation des temps scolaires et périscolaires, dans le cadre de la loi d'orientation et de programmation pour la refondation de l’école de la République du 8 juillet 2013, en Côte d'Or. L'enquête dont les résultats sont présentés ici repose sur un matériel substantiel récolté entre 2015 et 2017 formé par une base de données formée à partir de projets éducatifs territoriaux fournis par les communes volontaires. L'objectif de l'enquête était de faire un répertoire de l'offre périscolaire en Bourgogne et de la manière dont les territoires peuvent ou non constituer des ressources dans la mise en ouvre de la réforme, tout en prenant…
Improving color correction across camera and illumination changes by contextual sample selection
2012
International audience; In many tasks of machine vision applications, it is important that recorded colors remain constant, in the real world scene, even under changes of the illuminants and the cameras. Contrary to the human vision system, a machine vision system exhibits inadequate adaptability to the variation of lighting conditions. Automatic white bal- ance control available in commercial cameras is not sufficient to pro- vide reproducible color classification. We address this problem of color constancy on a large image database acquired with varying digi- tal cameras and lighting conditions. A device-independent color repre- sentation may be obtained by applying a chromatic adaptation…
