Deficiencies of regulation of euthanasia in legal acts of foreign countries
2014
Today in most countries the practising of euthanasia is not permissible and as in any case of a criminal offence, which endangers the life of a person, criminal liability applies here. However, the analysis of legal norms in foreign criminal codes reveals several deficiencies, ranging from – the absence of legal regulation which leads to a paradoxical situation, when ignoring the motive and aim of the offence, euthanasia is qualified according to the article of the criminal code which provides for liability for murder with no mitigating circumstances, but assisted suicide liability does not apply at all, – to including special legal norms pertaining to this problematic issue, in the structu…
EN COMPAÑÍA DE PAULO FREIRE: APRENDIENDO A DEVENIR
2021
RESUMEN El texto que sigue a continuación es un breve ejercicio de biograficidad, que sirve para seleccionar y ordenar algunos fragmentos de un itinerario académico y profesional jalonados por la presencia y la influencia del pedagogo brasileño Paulo Freire. La teoría de la biograficidad sostiene que la vida puede verse enriquecida con su relato, y que este contribuye a reordenar y dar sentido a las acciones del pasado y en curso. Este relato privilegia los momentos en los que el autor ha contado con la influencia –con la compañía intelectual y humana– de Paulo Freire. Sin duda, el mundo se ha enriquecido notablemente con la conversación, a la que me han invitado los escritos de Paulo Freir…
Photo-assisted formation of a chelating diphos ligand from PPh3 and a cyclometallated [P(C6H4)(C6H5)2]− ligand. Crystal structure of Pd{η2-o-[P(C6H5)…
2000
Abstract The cyclometallated palladium compound, Pd[η2-(C6H4)P(C6H5)2]Br[P(C6H5)3] (1), in the solid state by action of light, evolves to give Pd{η2-o-[P(C6H5)2]2(C6H4)}Br2 (2). This compound contains the diphosphine, o-[P(C6H5)2]2(C6H4), as chelated ligand that is formed by a couple reaction of the metallated ligand η2-[(C6H4)P(C6H5)2]− and the coordinated arylphosphine. A study by NMR spectroscopy confirms that the o-phenylene bridge in the diphosphine ligand in 2 comes from the metallated phosphine ligand in 1.
Analysis of the human a-wave ERG component
2006
The a-wave is one of the main issues of research in the field of ocular electrophysiology, since it is strictly connected with early photoreceptoral activities. The present study proposes mathematical methods that analyse this component in human subjects, and supports experimental evidence relating to possible correlations among the responses of photoreceptoral units under a light stimulus. The investigation is organized in two parts: the first part concerns the onset and the initial slope, up to the first minimum (about 10-15 ms), the second part deals with the main portion of the wave, up to about 30 ms. In both cases, the a-waves, recorded at various levels of luminance, have been fitted…
Dynamic laser speckle analyzed considering inhomogeneities in the biological sample
2017
Dynamic laser speckle phenomenon allows a contactless and nondestructive way to monitor biological changes that are quantified by second-order statistics applied in the images in time using a secondary matrix known as time history of the speckle pattern (THSP). To avoid being time consuming, the traditional way to build the THSP restricts the data to a line or column. Our hypothesis is that the spatial restriction of the information could compromise the results, particularly when undesirable and unexpected optical inhomogeneities occur, such as in cell culture media. It tested a spatial random approach to collect the points to form a THSP. Cells in a culture medium and in drying paint, repr…
Spatio-Chromatic Adaptation via Higher-Order Canonical Correlation Analysis of Natural Images
2014
Independent component and canonical correlation analysis are two general-purpose statistical methods with wide applicability. In neuroscience, independent component analysis of chromatic natural images explains the spatio-chromatic structure of primary cortical receptive fields in terms of properties of the visual environment. Canonical correlation analysis explains similarly chromatic adaptation to different illuminations. But, as we show in this paper, neither of the two methods generalizes well to explain both spatio-chromatic processing and adaptation at the same time. We propose a statistical method which combines the desirable properties of independent component and canonical correlat…
How to validate similarity in linear transform models of event-related potentials between experimental conditions?
2014
Abstract Background It is well-known that data of event-related potentials (ERPs) conform to the linear transform model (LTM). For group-level ERP data processing using principal/independent component analysis (PCA/ICA), ERP data of different experimental conditions and different participants are often concatenated. It is theoretically assumed that different experimental conditions and different participants possess the same LTM. However, how to validate the assumption has been seldom reported in terms of signal processing methods. New method When ICA decomposition is globally optimized for ERP data of one stimulus, we gain the ratio between two coefficients mapping a source in brain to two…
Des Translators neue Kleider. Die Translationwirtschaft in Zeiten von Digitalisierung, Datafizierung und Big Data Management
2017
Abstract The Internet of things will influence all professional environments, including translation services. Advances in machine learning, supported by accelerating improvements in computer linguistics, have enabled new systems that can learn from their own experience and will have repercussions on the workflow processes of translators or even put their services at risk in the expected digitalized society. Outsourcing has become a common practice and working in the cloud and in the crowd tend to enable translating on a very low-cost level. Confronted with promising new labels like Industry 4.0 and Work 4.0, professional freelance translators will have to organize themselves as smart office…
On-line assessment of comprehension processes
2009
In this paper we describe a new version of a former paper-and-pencil standardized comprehension test called Test of Comprehension Processes (Vidal-Abarca, Gilabert, Martínez, & Sellés, 2007). The new version has been adapted to a computer-based environment based on the moving window technique. It can be used to assess comprehension strategies of students from fifth to tenth grades (11 to 16 years old). Comprehension strategies are registered on-line using reading times and visits to relevant sections of the text during the question-answering process. Data show that the computerbased version draws similar results to those provided by the paper-and-pencil version. In addition, we identify the…
Exploring the cross-linguistic transfer of reading skills in Spanish to English in the context of a computer adaptive reading intervention
2017
ABSTRACTWe explore the potential of a computer-adaptive decoding game in Spanish to increase the decoding skills and oral reading fluency in Spanish and English of bilingual students. Participants were 78 first-grade Spanish-speaking students attending bilingual programs in five classrooms in Texas. Classrooms were randomly assigned to the treatment (i.e., where students played Graphogame Spanish) for 16 weeks for ten minutes per day (n = 3) versus business as usual instruction (n = 2). Results indicate that students at some risk on Spanish pseudoword reading appeared to benefit the most from playing the game. Analysis of gains suggests a potentially small, but meaningful educational effect…
