In this paper we position ourselves against idealist presuppositions so frequent in the humanities and social sciences, and, particularly, in communication theory. We argue that a realist approach to the study of communication avoiding such implausible assumptions is not only possible, but has already been exemplified in proposals that take communication to be a phenomenon with a biological origin. We argue that this sort of perspective can account for the variety of communicative functions we encounter in human experience, including the ones involving senses.

The traditional point of view on analyticity implies that truth in virtue only of meaning entails a priori acceptability and vice versa. The argument for this claim is based on the idea that meaning as it concerns truth and meaning as it concerns competence are one and the same thing. In this paper I argue that the extensions of these notions do not coincide. I hold that truth in virtue of meaning— truth for semantic reasons—doesn't imply a priori acceptability, and that a priori reflection based only on knowledge of meaning—in the sense of competence—doesn't necessitate true conclusions.The main consequence of this view concerns conceptual analysis, as it presupposes we have a privileged—incorrigible in the face of empirical evidence—access to non‐trivial truths about the world on the basis of mere a priori reflection founded on meaning. If, as I argue, such access is not incorrigible the project of conceptual analysis loses its special epistemological status.

This paper presents a mathematical framework for the study of the information contained in audiovisual contents based on the development by Keith Devlin of Situation Theory. In order to obtain this framework, we present accounts of the processes carried out by agents from the reception of audiovisual contents to the extraction of information, in accordance with the definition by Israel and Perry. We finally justify why these accounts concerning the extraction of information from audiovisual content can be included as part of a mathematical formulation of Situation Theory

El concepto actual de limpieza refleja la evolución que la conservación-restauración ha tenido durante el siglo XX. Gracias al desarrollo de las ciencias y a la formación de los conservadores-restauradores se le ha ido añadido añadiendo un carácter científicotécnico— limpieza ideal — y se ha profesionalizado la intervención — limpieza real —. En este trabajo, a partir de la definición de limpieza en Patrimonio Arquitectónico y de determinados preceptos implícitos al tratamiento (estética, conservación, catas previas, evaluación, etc.), se analiza la normativa específica en la materia para comprobar su vigencia y adaptación a las necesidades reales de intervención. Tras plantear diversas cuestiones sobre el tratamiento se puede concluir que, si bien el estudio científico de las catas previas de limpieza es algo habitual, no se ha determinado cómo plantear un seguimiento efectivo de los trabajos según los baremos establecidos en dichos estudios.
