In this article, the dominant legitimating discursive strategies around the ever-increasing labour demands and ever-declining standards of safety and well-being at work in Spain are analysed through the lens of Boltanski and Thévenot’s (2006) view of the transformation of capitalism. A qualitative methodology based on semi-structured interviews is used. Results show that the justificatory arguments most commonly put forward by managers and experts are the logic of supply and demand, and values related to flexibility, resilience and adaptability to change. In (...) contrast, the stability and protection established in the twentieth century are widely cherished values, particularly among union representatives and some human resources specialists. We found that discourse practices map two specific legitimating categories (market values and a projects orientation), and one critical category (Civic World), but the critical category has no practical impact, as the predominant feeling is resignation. Our research describes the common attitudes to legitimacy in the job market and points to a deep discontent in some of its key agents. (shrink)

El artículo presenta la concepción de filosofía de Jürgen Habermas, en distintos momentos de su trayectoria intelectual, resaltando el carácter polémico de su toma de posición frente a las concepciones metafísicas y posmodernas del quehacer filosófico.

A partir de dos hechos: las reiteradas referencias a la doctrina de los sentidos espirituales en los teólogos monásticos medievales y el olvido de la misma por parte de los autores posteriores, nos aproximamos a este "conocimiento experimental", desde la filosofía y la teología, partiendo de algunos testimonios de los siglos XI al XIII, especialmente los referidos a la lectio divina y al opus Dei, implorando también con ellos "Accende lumen sensíbus".

Aim: The present work proposes the study of the neuromotor activity of the masseter-jaw-tongue articulation during diadochokinetic exercising to establish functional statistical relationships between surface Electromyography, 3D Accelerometry, and acoustic features extracted from the speech signal, with the aim of characterizing Hypokinetic Dysarthria. A database of multi-trait signals of recordings from an age-matched control and PD participants are used in the experimental study. Hypothesis: The main assumption is that information between sEMG and 3D acceleration, and acoustic features may be quantified (...) using linear regression methods. Methods: Recordings from a cohort of eight age-matched control participants and eight PD participants were collected during the utterance of a diadochokinetic exercise. The dynamic and acoustic absolute kinematic velocities produced during the exercises were estimated by acoustic filter inversion and numerical integration and differentiation of the speech signal. The amplitude distributions of the absolute kinematic and acoustic velocities are estimated to allow comparisons in terms of Mutual Information. Results: The regression results show the relationships between sEMG and dynamic and acoustic estimates. The projection methodology may help in understanding the basic neuromotor muscle activity regarding neurodegenerative speech in remote monitoring neuromotor and neurocognitive diseases using speech as the vehicular tool, and in the study of other speech-related disorders. The study also showed strong and significant cross-correlations between articulation kinematics, both for the control and the PD cohorts. The absolute kinematic variables presents an observable difference for the PD participants compared to the control group. Conclusion: Kinematic distributions derived from acoustic analysis may be useful biomarkers toward characterizing HD in neuromotor disorders providing new insights into PD. (shrink)

Este trabajo tiene como objetivo responder a las críticas al liberalismo formuladas en un reciente trabajo de Carlos Kohn. Para mostrar esto expondré, en primer lugar, por qué pienso que Kohn generaliza ilegítimamente una concepción bastante estrecha de liberalismo, relacionada con la economía. En segundo lugar, por qué pienso que Kohn generaliza ilegítimamente una concepción bastante estrecha de liberalismo, relacionada con la economía. En segundo lugar señalaré los límites de esa concepción, y cómo puede definirse otra más comprehensiva, en la (...) que enmarcaré la mayor parte del liberalismo político contemporáneo y, un tanto audazmente, el contractualismo clásico de Hobbes. En tercer lugar, trataré de mostrar que esta versión comprehensiva es una razonable descripción de la política, que no depende lógicamente de suposiciones dudosas sobre los presupuestos y requisitos de la economía de mercado y que, por ello, escapa indemne a la crítica de Kohn.

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)
