El pragmatismo trascendental y dialógico de Jürgen Habermas

La discusión propuesta se divide en dos mitades. En la primera parte, defendemos una interpretación de la teoría de la pragmática universal en términos de pragmatismo trascendental, muy en la línea de las propuestas firmadas por Karl-Otto Apel. En la segunda parte, nos solidarizamos con la idea de Pere Fabra según la cual el uso comunicativo del lenguaje difícilmente puede sentar las bases de todos los fines ilocutivos en que consisten los actos de habla.Palabras clave: Filosofía del lenguaje, pragmática universal, pragmatismo trascendental, actos de habla, racionalidad comunicativa, Jürgen Habermas.AbstractThe proposed discussion consists of two sections.

Near-critical free-surface flows: Real fluid flow analysis

An open channel flow with a flow depth close to the critical depth is characterised by a curvilinear streamline flow field that results in steady free surface undulations. Near critical flows of practical relevance encompass the undular hydraulic jump when the flow changes from supercritical (F > 1) to subcritical (F 1). So far these flows were mainly studied based on ideal fluid flow computations, for which the flow is assumed irrotational and, thus, shear forces are absent. While the approach is accurate for critical flow conditions (F = 1) in weir and flumes, near-critical flows involve long distances reaches, and the effect of friction on the flow properties cannot be neglected. In the present study the characteristics of near-critical free-surface flows are reanalysed based on a model accounting for both the streamline curvature and friction effects. Based on the improved model, some better agreement with experimental results is found, thereby highlighting the main frictional features of the flow profiles

Synthesis and characterization of hybrid organic-inorganic materials based on sulphonated polyamideimide and silica

The preparation of hybrid organic–inorganic membrane materials based on a sulphonated polyamideimide resin and silica filler has been studied. The method allows the sol–gel process to proceed in the presence of a high molecular weight polyamideimide, resulting in well dispersed silica nanoparticles (<50 nm) within the polymer matrix with chemical bonding between the organic and inorganic phases. Tetraethoxysilane (TEOS) was used as the silica precursor and the organosilicate networks were bonded to the polymer matrix via a coupling agent aminopropyltriethoxysilane (APTrEOS). The structure and properties of these hybrid materials were characterized via a range of techniques including FTIR, TGA, DSC, SEM and contact angle analysis. It was found that the compatibility between organic and inorganic phases has been greatly enhanced by the incorporation of APTrEOS. The thermal stability and hydrophilic properties of hybrid materials have also been significantly improved

Unconscious or underpowered? Probabilistic cuing of visual attention

Recent debate about the reliability of psychological research has raised concerns about the prevalence of false positives in our discipline. However, false negatives can be just as concerning in areas of research that depend on finding support for the absence of an effect. This risk is particularly high in unconscious learning experiments, where researchers commonly seek to demonstrate that people can learn to perform a task in the absence of any explicit knowledge of the information that drives performance. The fact that some unconscious learning effects are typically studied with small samples and unreliable awareness measures makes false negatives especially likely. In the present article we focus on a popular unconscious learning paradigm, probabilistic cuing of visual attention, as a case study. Firstly, we show that, at the meta-analytic level, previous experiments reveal positive signs of participant awareness, although individual studies are severely underpowered to detect this. Secondly, we report the results of two empirical studies in which participants’ awareness was tested with alternative and more sensitive dependent measures, both of which manifest positive evidence of awareness. We also show that, based on the predictions of a formal model of probabilistic cuing and given the reliabilities of the dependent measures collected in these experiments, any statistical test aimed at detecting a significant correlation between learning and awareness is doomed to return a non-significant result, even if at the latent level both constructs are actually related and participants’ knowledge is completely explicit
