    Semiótica del consumo. Metodología para el análisis publicitario desde una perspectiva integral
    (2025-03-01)
    The aim of this article is to propose a consistent methodological approach for the analysis of advertising discourse and consumption practices from a perspective that integrates market economy semiotically as context. It argues that there is an epistemological limitation in semiotic analysis of consumption due to methodological commitments during the analysis procedure. Thus, advertising and consumption semiotics, limited to the analysis of a single text (commercial, billboard, advertisement), assume their object of study as abstracted from social relations. From this “monotextual” viewpoint, the consumer society is conceived as a contextual production framework that does not participate in the semiotic interpretation of advertising materials. This article advocates for a semiotics capable of integrating advertising discourses, consumption practices, and various historical processes of the market economy by considering them as texts. To achieve this, it presents the methodological approach assuming an expanded notion of textuality, affirming the market economy as part of the production of meaning in advertising materials. Once the context (economy) is established as another text, three main logics (practical-critical/manufacture, utopian/semiocapitalism, and ludic/hyperconsumption) are identified between advertising discourse and consumption practices. This methodological model stands as an analytical tool for the analysis of advertising discourse.

    An upper bound for the GSV-index of a foliation
    (Springer Science+Business Media, 2025-04-01)
    Let F be a holomorphic foliation at p∈C2, and let B be a separatrix of F. We prove the following upper bound GSVp(F,B)≤4τp(F,B)-3μp(F,B), where GSVp(F,B) is the Gómez-Mont-Seade-Verjovsky index of the foliation F with respect to B, μp(F,B) is the multiplicity of F along B and τp(F,B) is the dimension of the quotient of C{x,y} by the ideal generated by the components of any 1-form defining F and any equation of B.

    AI IN JUSTICE: BALANCING EFFICIENCY AND EXPLICABILITY
    (Marcial Pons Librero, 2026-01-01)
    AI systems intended for use in judicial procedure carry a significant commitment to efficiency –understood from an instrumental perspective– for which accurate predictions are paramount. However, if an AI system has this objective, it is inevitable that explicability will inevitably decrease. This means that the program's algorithms are not comprehensible to humans, and often, neither is its output. From an AI ethics standpoint, AI systems applied in the field of justice should possess a significant degree of explicability, yet this compromises efficiency. Therefore, this paper aims to 1) highlight the tension between efficiency and explicability; and 2) argue that, even adopting an AI human-centred approach, opaque systems prioritizing efficiency could be justified, depending on the specific function of the system; specifically, in the greater or lesser degree of interference with the judicial decision that must be justified.
