Diversos autores plantean la centralidad analítica del tándem europeo Alemania-Francia (también referido como ‘eje francoalemán’) durante el desarrollo de las negociaciones, en contraposición a un tándem Brasil-Argentina por el lado del Mercosur. El objetivo de este trabajo es problematizar la dinámica de funcionamiento del mencionado tándem en el contexto de expansión de la Unión Europea hacia el este a comienzos del nuevo milenio. Entendemos que las tensiones, alineamientos y realineamientos nacionales durante aquel proceso, al igual que otros sucesos de relevancia (...) que escapan a los objetivos de este trabajo, nos ofrecen material necesario para desplegar y analizar la dinámica de liderazgo europeo entre el tándem mencionado y otros actores relevantes, como el Reino Unido y los órganos institucionales de la Unión.

This work considers the formalisation of the merging process of stratified belief bases, where beliefs are stored in different layers or strata. Their strata are ranked, following a total order, employing the value the agent using the belief base assigns to these beliefs. The agent uses an argumentation mechanism to reason from the belief base and obtain the final inferences. We present two ways of merging stratified belief bases: the first is defined by merging two strata without belief preservation, and (...) the second by merging two strata with belief preservation. For these operators, as layers merge, it is possible that some information has to be deleted from the stratum to maintain consistency. The latter merge operator will be defined as performing their actions so that information removed from the stratum is preserved after the merging by moving it to a stratum containing information perceived as having a lower value and where those beliefs may trigger a new revision, possibly starting a cascading effect.

The Einstein–Podolsky–Rosen–Bohm (EPRB) experiment performed with random variable and spatially separated analyzers is a milestone test in the controversy between Objective Local Theories (OLT) and Quantum Mechanics (QM). Only a few OLT are still possible. Some of the surviving OLT (specifically, the so called non-ergodic theories) would be undetectable in the averaged statistical values, but they may leave their trace in the time dynamics. For, while QM predicts random processes, the OLT of this kind predict the existence of regularities that (...) may be revealed as a low dimensional object in the phase space. We perform a numerical analysis of the time-resolved data recorded in that experiment to unveil any hypothetical low dimensional dynamics that may be present. We find no consistent indication of such dynamics except for one data file, the longest of all in the real time. The possible causes of these dynamics are discussed. (shrink)

We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the rejection of (...) some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)

In 2016, Béziau introduces a restricted notion of paraconsistency, the so-called genuine paraconsistency. A logic is genuine paraconsistent if it rejects the laws $\varphi,\neg \varphi \vdash \psi$ and $\vdash \neg (\varphi \wedge \neg \varphi)$. In that paper, the author analyzes, among the three-valued logics, which of them satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above-mentioned are $\vdash \varphi, \neg \varphi$ and $\neg (\varphi \vee \neg \varphi) \vdash$. We call genuine paracomplete logics those rejecting (...) the mentioned properties. We present here an analysis of the three-valued genuine paracomplete logics. A very natural twist structures semantics for these logics is also found in a systematic way. This semantics produces automatically a simple and elegant Hilbert-style characterization for all these logics. Finally, we introduce the logic LGP which is genuine paracomplete is not genuine paraconsistent, not even paraconsistent and cannot be characterized by a single finite logical matrix. (shrink)

In this paper we propose an approach to multi-source belief revision where the trust or credibility assigned to informant agents can be revised. In our proposal, the credibility of each informant represented as a strict partial order among informant agents, will be maintained in a repository called credibility base. Upon arrival of new information concerning the credibility of its peers, an agent will be capable of revising this strict partial order, changing the trust assigned to its peers accordingly. Our goal (...) is to formalize a set of change operators over the credibility base: expansion, contraction, prioritized, and non-prioritized revision. These operators will provide the capability of dynamically modifying the credibility of informants considering the reliability of the information. This dynamics will reflect a new perception of trust assigned to the informant, or extend the set of informants by admitting the addition of new informant agents. (shrink)

En el siguiente estudio se evalúa un panorama con respecto al comportamiento sociológico en un preámbulo tanto antes durante y después de esta crisis social que se está viviendo debido a la pandemia de hoy en día. Por ello para sustentar dicha investigación se realizó un censo en el cuál, mediante el uso de herramientas estadísticas, se pudo realizar una comparación entre un antes y un durante de la pandemia, lo cual facilitaría intrínsicamente a la predicción de una denominada post (...) pandemia. En este texto se pretende detallar el proceso y forma de la encuesta, al igual que los resultados obtenidos de la misma. Se proveen, además, posibles explicaciones para estos resultados, guiándose por las restricciones de salud nacionales como posibles razones para el cambio de comportamiento actual.

In this paper we introduce a formalism for single-agent decision making that is based on Dynamic Argumentation Frameworks. The formalism can be used to justify a choice, which is based on the current situation the agent is involved. Taking advantage of the inference mechanism of the argumentation formalism, it is possible to consider preference relations, and conflicts among the available alternatives for that reasoning. With this formalization, given a particular set of evidence, the justified conclusions supported by warranted arguments will (...) be used by the agent’s decision rules to determine which alternatives will be selected. We also present an algorithm that implements a choice function based on our formalization. Finally, we complete our presentation by introducing formal results that relate the proposed framework with approaches of classical decision theory. (shrink)

This article deals with the relationship between the creator of psychoanalysis, Sigmund Freud, and the Latvian-born Chilean professor of physiology – and endocrinologist and anthropologist – Alejandro (or Alexander) Lipschütz. Up till now, the historiography of psychoanalysis in Chile has ignored the existence of this relationship, that is to say, the fact that there exists an interesting exchange of correspondence as well as references to Lipschütz in some important works published by Freud and in Freud’s correspondence with the Hungarian (...) psychoanalyst Sándor Ferenczi. There are also references to works on psychoanalysis carried out by Lipschütz in Chile. The Freud–Lipschütz relationship allows us to examine two interesting topics in contemporary historiographical approaches to psychoanalysis. First, it permits us to reflect on the connections that Freud and Ferenczi sought to establish between psychoanalysis and biology (endocrinology in particular) as a strategy to address criticism of the scientific foundations of psychoanalysis and, therefore, to help legitimize psychoanalysis in the field of science. Second, the relationship between Freud, working in a culturally influential city such as Vienna, and Lipschütz, working in a ‘peripheral’ country such as Chile, paves the way to reflect on the consequences of a history of psychoanalysis written from the perspective of the ‘margins’. This is a history that focuses not on regions where early industrialization and modernization processes, along with an important academic and scientific tradition, help explain the interest in and reception of psychoanalysis, but on regions where different sets of conditions have to be examined to explain appropriation and dissemination processes.

Este ensayo se propone mostrar que, a pesar de la relevancia de la interpretación alejandrina del intelecto agente aristotélico (que Alejandro identifica con dios), tal interpretación no puede ser correcta por razones de orden sistemático que irían en contra de algunas premisas aristotélicas básicas, tanto ontológicas en general como de su noética y psicología en particular. En el desarrollo de su argumento general Boeri destaca la relevancia de algunos argumentos y explicaciones de Pseudo Filópono, quien (correctamente a su juicio) (...) se esfuerza por anclar el problema del intelecto del lado psicológico, lo cual presupone que el intelecto debe tener un “soporte” corpóreo. Una consecuencia de su examen es, según Boeri, que no sólo la interpretación de Alejandro del intelecto agente no constituye una correcta exégesis de De anima III 5, sino también que, al identificar al intelecto agente con el “intelecto que viene de afuera”, con dios y con la causa primera, Alejandro introduce una importante incoherencia dentro de su propia concepción psicológica que reconoce la tesis de Aristóteles de que los estados anímicos “se dan” a través del cuerpo.

Mi meta en este ensayo es, primero, reconstruir los puntos de vista de Marcelo Dascal en relación con las controversias filosóficas y, en segundo lugar, someterla a un examen crítico. Dejo en claro que las tesis de Dascal tienen un amplio rango de aplicaciones. Mi crítica se centra alrededor del concepto de conocimiento y de la idea misma de reconstrucción pragmática. Considero también la sugerente conexión que Dascal establece entre las controversias y el progreso intelectual.

Defeasible argumentation has been applied successfully in several real-world domains in which it is necessary to handle incomplete and contradictory information. In recent years, there have been interesting attempts to carry out argumentation processes supported by massive repositories developing argumentative reasoning applications. One of such efforts builds arguments by retrieving information from relational databases using the DBI-DeLP framework; this article presents eDBI-DeLP, which extends the original DBI-DeLP framework by providing two novel aspects which refine the interaction between DeLP programs and (...) relational databases. First, we expand the expressiveness of dbi-delp programs by providing ways of controlling how the information in databases is recovered; this is done by introducing filters that enable an improved fine-grained control on the argumentation processes which become useful in applications, providing the semantics and the implementation of such filters. Second, we introduce an argument comparison criterion which can be adjusted at the level of literals to model particular features such as credibility and topic expertise, among others. These new tools can be particularly useful in environments such as medical diagnosis expert systems, decision support systems, or recommender systems based on argumentation, where datasets are often provided in the form of relational databases.

Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da Costa's calculi (...) C_n. This produces a novel decision procedure for these logics. Moreover, we show that the RNmatrix semantics proposed here induces naturally a labelled tableau system for each C_n, which constitutes another decision procedure for these logics. This new semantics allows us to conceive da Costa's hierarchy of C-systems as a family of (non deterministically) (n+2)-valued logics, where n is the number of "inconsistently true" truth-values and 2 is the number of "classical" or "consistent" truth-values, for every C_n.

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

Whilst he was writing De principatibus, was Machiavelli really as out of touch with the Florentine politico-institutional world as his letter of December 1513 claims? Who read Il principe prior to its publication, and how? Why did the philosopher Agostino Nifo, one of the major proponents of Renaissance Averroism, plagiarize it? To what extent is the Machiavellian "principato civile" comprehensible only by way of its Medicean and Florentine affiliation? Did the young Lorenzo de' Medici's political programme seek to eliminate the (...) Roman church? What politicocultural stance is hidden behind certain political terms from the humanist tradition that Machiavelli revisited in Il principe? To what extent was the Machiavellian relationship between animality and humanity, simulation and dissimulation, influenced by Leonardo da Vinci's ceuvre? And, finally, what are the questions that remain open in Il principe? This compilation offers some possible answers to these questions, thus providing new critical tools for the study of Niccolo Machiavelli's Il principe -- Back cover. (shrink)

Diversos estudios han concluido que los pacientes con daño en la Corteza Frontal –CF– o Corteza Prefrontal Ventromedial –CPV– muestran una disposición a herir directamente a otra persona con el fin de salvar varias vidas en sus respuestas a los “dilemas morales personales”, revelando una posible carencia de empatía. No obstante, cuando evalúan conductas carentes de empatía sin justificación utilitarista, sus respuestas son normales. Defendemos aquí que los pacientes sufren una deficiencia cognitiva relacionada con la hipótesis de marcador somático de (...) Damasio y con juicios de valor. Criticamos la hipótesis del “paciente utilitarista”, que se ha atrincherado en la neurociencia cognitiva. (shrink)

Civic Humanism is one de most relevant theories in present day political philosophy. Its main characteristics are the rejection of radical individualism, the emphasis on the social and political responsibility of citizens, and the consideration that the realisation of a mature personality is only possible through communities on pre-political and pre-economical levels. The author of this paper maintains that there is a continuity from the start of Civic Humanism in Renaissance until its revival in XX Century. He defends as well (...) that the philosophical roots of Civic Humanism can be found in the aristotelian practical philosophy, especially in the notions of good citizen, good life, common good and teleological praxis.
