Hacia la ley europea del clima: las evaluaciones científicas y el futuro papel de las respuestas jurídicas de los estados miembros
2021
Los problemas climáticos son temas persistentes y omnipresentes dentro de las políticas y legislaciones contemporáneas, que exigen un enfoque interdisciplinario para promover soluciones jurídicas adecuadas para la complejidad del tema. Paradójicamente, las propagandas negacionistas, lejos de bloquear las acciones climáticas, las han propiciado, lo que ha llevado al establecimiento de un organismo científico super partes que reconociese las cuestiones climáticas a través de informes científicos avanzados: el Grupo Intergubernamental de Expertos sobre el Cambio Climático de la ONU (IPCC). Desde entonces, muchos países han usado los hallazgos del IPCC como base científica para desarrollar polí…
Primeras consideraciones a la Ley Orga?nica 3/2021, de 24 de marzo, de regulación de la eutanasia. el reconocimiento de un nuevo derecho
2021
The aim of this paper is to carry out a brief study of the recent Organic Law 3/2021, of March 24, on the regulation of euthanasia (BOE. March 25, 2021) approved in Spain, from a constitutional perspective, highlighting its main aspects. The matter under study is not exempt from controversy because it covers legal, medical and ethical considerations of great complexity.
Espais de formació de la responsabilitat social universitària
2018
L’article està basat en l’experiència de les «Jornadas de ‘Humanismo y Universidad’» celebrades a la Escuela Universitaria de Trabajo Social «Ntra. Sra. del Camino» amb l’objectiu de contribuir al desenvolupament d’iniciatives innovadores en la formació de la Responsabilitat Social Universitària (RSU) i, així, fomentar accions que involucren els diferents agents implicats, inclosos els beneficiaris finals, en els processos d’innovació i la cerca d’un aprenentatge socialment responsable. Les Jornades constitueixen una «bona pràctica», que permet obtindre i mesurar resultats significatius per a definir els elements que determinen l’efectivitat d’aquesta pràctica, l’aplicació de la qual se sit…
Adolescents en conflicte amb la llei: víctimes o victimàries?: una aproximació des de la sociologia i el treball social
2008
En éste artículo se realiza un aproximación al fenómeno de la delincuencia juvenil, desde el paradigma de la vulnerabilidad y la exclusión social. Desde ésta aproximación se realiza la investigación en un territorio concreto, como es el municipio de Burjassot en el área metropolitana de València (País Valencià), se profundiza en las variables de vulnerabilidad de éstos adolescentes, lo que nos permite relacionar su realidad con la nueva cuestión social. El trabajo incide en la complejidad del fenómeno, huyendo de explicaciones lineales y sencillas, extrayendo como variables fundamentales a investigar: la realidad educativa, el barrio de residencia en el municipio, la existencia previa de in…
A new set of 299 pictures for psycholinguistic studies : French norms for name agreement, image agreement, conceptual familiarity, visual complexity,…
2003
Pictures are often used as stimuli in studies of perception, language, and memory. Since performances on different sets of pictures are generally contrasted, stimulus selection requires the use of standardized material to match pictures across different variables. Unfortunately, the number of standardized pictures available for empirical research is rather limited. The aim of the present study is to provide French normative data for a new set of 299 black-and-white drawings. Alario and Ferrand (1999) were closely followed in that the pictures were standardized on six variables: name agreement, image agreement, conceptual familiarity, visual complexity, image variability, and age of acquisit…
Earlier timbre processing of instrumental tones compared to equally complex spectrally rotated sounds as revealed by the mismatch negativity.
2014
Harmonically rich sounds have been shown to be processed more efficiently by the human brain compared to single sinusoidal tones. To control for stimulus complexity as a potentially confounding factor, tones and equally complex spectrally rotated sounds, have been used in the present study to investigate the role of the overtone series in sensory auditory processing in non-musicians. Timbre differences in instrumental tones with equal pitch elicited a MMN which was earlier compared to that elicited by the spectrally rotated sounds, indicating that harmonically rich tones are processed faster compared to non-musical sounds without an overtone series, even when pitch is not the relevant infor…
The facilitative effect of gestures on the neural processing of semantic complexity in a continuous narrative
2019
© 2019 Elsevier Inc. Gestures are elemental components of social communication and aid comprehension of verbal messages; however, little is known about the potential role of gestures in facilitating processing of semantic complexity in an ecologically valid setting. The goal of this study was to investigate whether cognitive load, as indexed by semantic complexity, is modulated by the presentation of gestures accompanying speech. Twenty healthy participants watched 16 video clips of a short narrative while instructed to carefully listen to and watch the narrator while functional magnetic resonance imaging (fMRI) data were acquired. The videos contained passages with and without various co-s…
Instantaneous Transfer Entropy for the Study of Cardiovascular and Cardio-Respiratory Nonstationary Dynamics
2017
Objective: Measures of transfer entropy (TE) quantify the direction and strength of coupling between two complex systems. Standard approaches assume stationarity of the observations, and therefore are unable to track time-varying changes in nonlinear information transfer with high temporal resolution. In this study, we aim to define and validate novel instantaneous measures of TE to provide an improved assessment of complex nonstationary cardiorespiratory interactions. Methods: We here propose a novel instantaneous point-process TE (ipTE) and validate its assessment as applied to cardiovascular and cardiorespiratory dynamics. In particular, heartbeat and respiratory dynamics are characteriz…
Differences in sensory processing of German vowels and physically matched non-speech sounds as revealed by the mismatch negativity (MMN) of the human…
2014
We compared processing of speech and non-speech by means of the mismatch negativity (MMN). For this purpose, the MMN elicited by vowels was compared to those elicited by two non-speech stimulus types: spectrally rotated vowels, having the same stimulus complexity as the speech stimuli, and sounds based on the bands of formants of the vowels, representing non-speech stimuli of lower complexity as compared to the other stimulus types. This design allows controlling for effects of stimulus complexity when comparing neural correlates of processing speech to non-speech. Deviants within a modified multi-feature design differed either in duration or spectral property. Moreover, the difficulty to d…
Clinical features, disease progression and use of healthcare resources in a large sample of 866 patients from 24 headache centers: A real-life perspe…
2021
Objective: To develop a dedicated Italian chronic migraine (CM) database (IRON project) to overcome disease misconceptions, improve clinical administration, reduce patients' burden, and rationalize economic resource allotment.Background: Proper CM management requires a comprehensive appraisal of its full clinical, social, and economic complexity.Methods: In this cross-sectional study, CM patients were screened in 24 certified headache centers with face-to-face interviews. Information on sociodemographic factors, medical history, characteristics of CM, and of prior episodic migraine (EM), and healthcare resource use was gathered using a semistructured web-based questionnaire.Results: A total…
