We present a Hilbert-style axiomatization of a recently introduced logic, called G'3 G'3 is based on a 3-valued semantics. We prove a soundness and completeness theorem. The replacement theorem holds in G'3. As it has already been shown in previous work, G'3 can express some non-monotonic semantics. We prove that G'3can define the same class of functions as Lukasiewicz 3 valued logic. Moreover, we identify some normal forms for this logic.

In the Reality we know, we cannot say if something is infinite whether we are doing Physics, Biology, Sociology or Economics. This means we have to be careful using this concept. Infinite structures do not exist in the physical world as far as we know. So what do mathematicians mean when they assert the existence of ω? There is no universally accepted philosophy of mathematics but the most common belief is that mathematics touches on another worldly absolute truth. Many mathematicians (...) believe that mathematics involves a special perception of an idealized world of absolute truth. This comes in part from the recognition that our knowledge of the physical world is imperfect and falls short of what we can apprehend with mathematical thinking. The objective of this paper is to present an epistemological rather than an historical vision of the mathematical concept of infinity that examines the dialectic between the actual and potential infinity.

En este artículo defendemos el valor de la perspectiva de Ortega sobre el problema del anacronismo en historia. Para ello, exponemos dicho problema en la Escuela de París. Seguidamente, explicamos las aportaciones de Ortega sobre ese problema en los años 40. Finalmente, hacemos un balance de las aportaciones de Ortega y su actualidad.

English summary: Gilduin (1155) was, from 1113, the first abbot of the community of the Canons Regular of St Augustine, soon to become an abbey, under the auspices of St Victor of Marseille, on the left bank of the river Seine. After the death of his confrere Hugh, who was of German descent and the leading figure of the Victorines, on 11 February 1141, abbot Gilduin took care that the writings of Hugh were collected and compiled in a representative complete (...) edition. This 'Gilduin-edition' - as it is called in Medieval scholarship - comprises four volumes, the first of which is reconstructed herewith and presented in print. This volume follows the 2008 edition of Hugh's theological summa, De sacramentis christiane fidei. Then as now we are dealing with a critical albeit historical text. This new volume contains nine works, among which the first ever complete edition of Hugh's Cronica surely stands out. German description: Gilduin (+ 1155) war ab 1113 der erste Abt der einige Jahre zuvor gegrundeten und bald zur Abtei erhobenen Gemeinschaft von Augustinerchorherren unter dem Patronat des hl. Victor von Marseille, auf dem linken Ufer der Seine. Nach dem Tode seines Mitbruders Hugo, des aus Deutschland stammenden fuhrenden Kopfes der Viktoriner, am 11. Februar 1141 hat Abt Gilduin dafur gesorgt, daa die Schriften Hugos gesammelt und in einer reprasentativen Gesamtausgabe zusammengestellt werden. Diese in der internationalen mediavistischen Forschung so genannte,Gilduin-Ausgabe' der Werke Hugos von Saint-Victor umfaat vier Bande, deren erster hiermit rekonstruiert und im Druck vorgelegt wird. Dieser Band folgt somit auf unsere im Jahre 2008 besorgte Ausgabe der theologischen Summe Hugos, De sacramentis christiane fidei. Damals wie heute handelt es sich um einen kritischen, wenngleich historischen Text. Dieser neue Band umfaat neun Werke, unter denen insbesondere die uberhaupt erste vollstandige Ausgabe von Hugos Cronica hervorzuheben ist. (shrink)

The COVID-19 disease has caused thousands of deaths worldwide and required the rapid and drastic adoption of various protective measures as main resources in the fight to reduce the spread of the disease. In the present study we aimed to identify socio cognitive factors that may influence adherence to protective measures toward COVID-19 in a Spanish sample. This longitudinal study analyzes the predictive value of perceived severity and vulnerability of infection, self-efficacy, direct exposure to the virus, and instrumental focused coping (...) style for adhering to infection protection behaviors during the first months of the COVID-19 pandemic. It also tests sex and age differences in these factors and changes over time. A two-wave longitudinal study was conducted in March and April 2020 starting the day after a strict national lockdown was decreed in Spain. A path analysis was used to test direct and indirect effects between vulnerability and the adherence to protective behaviors. Results suggest that individuals' perceived severity and vulnerability to COVID-19 and instrumental coping strategies are related to the use of more protective behaviors. This coping strategy mediates the effect of perceived vulnerability on engaging in protective behaviors, and this effect depends on direct exposure to COVID-19 and perceived self-efficacy moderators. Results suggest that recognizing one's own abilities to engage in instrumental actions may facilitate adherence to protective measures in people who had not been directly exposed to COVID-19. Therefore, adopting instrumental coping strategies to manage an individual's perceived vulnerability to infection may positively impact the adherence to protective behaviors, especially during the onset of an unexpected threat and when there is no prior direct experience with the situation.

A chapter surveying Jerry Fodor's contributions to philosophy and cognitive science. In 12 Modern Philosophers, edited by Christopher Belshaw and Gary Kemp.

Background:The acquisition of experience is a major concern for nurses in intensive care units. Although the emotional component of the clinical practice of these nurses has been widely studied, greater examination is required to determine how this component influences their learning and practical experience.Objective:To discover the relationships between emotion, memory and learning and the impacts on nursing clinical practice.Research design:This is a qualitative phenomenological study. The data were collected from open, in-depth interviews. A total of 22 intensive care unit nurses (...) participated in this research between January 2012 and December 2014.Ethical considerations:The School of Nursing Ethics Committee approved the study, which complied with ethical principles and required informed consent.Findings:We found a clear relationship between emotion, memory and the acquisition of experience. This relationship grouped three dimensions: (1) satisfaction, to relieve the patient’s pain or discomfort, give confidence and a sense of security to the patient, enable the presence of family members into the intensive care unit and provide family members with a realistic view of the patient’s situation; (2) error experience, which nurses feel when a patient dies, when they fail to accompany a patient in his or her decision to abandon the struggle to live or when they fail to lend support to the patient’s family; and (3) the feel bad–feel good paradox, which occurs when a mistake in the patient’s care or handling of his or her family is repaired.Conclusion:Emotion is a capacity that impacts on nurses’ experience and influences improvements in clinical practice. Recalling stories of satisfaction helps to reinforce good practice, while recalling stories of errors helps to identify difficulties in the profession and recognise new forms of action. The articulation of emotional competencies may support the development of nursing ethics in the intensive care unit to protect and defend their patients and improve their relationships with families in order to maximise the potential for patient care.

Consider any subvariety of BL-algebras generated by a single BL-chain which is the ordinal sum of the standard MV-algebra on [0, 1] and a basic hoop H. We present a geometrical characterization of elements in the finitely generated free algebra of each of these subvarieties. In this characterization there is a clear insight of the role of the regular and dense elements of the generating chain. As an application, we analyze maximal and prime filters in the free algebra.

Julián Marías es uno de los pensadores humanistas más completos del siglo XX y uno de los intelectuales más grandes de la España contemporánea. La presente obra pretende fijar de un modo muy detallado su aportación personal y filosófica al pensamiento universal. El resultado ha sido un riguroso trabajo pluridisciplinar que, desde un planteamiento divulgativo, reúne por primera vez a los mejores conocedores de su vida y su obra.

El presente artículo trata de responder la decisiva cuestión qué es la vida personal desde la perspectiva de la rehumanización. Para ello se revisan las dos concepciones del ser humano opuestas que subyacen en la filosofía contemporánea desde sus comienzos: una visión antropológica trascendente de la vida emparentada con la filosofía de Sören Kierkegaard, y una visión antropológica inmanente de la vida emparentada con la filosofía de Friedrich Nietzsche. Este análisis nos va a permitir proponer una filosofía de la rehumanización (...) en clave de Ciencias de la Persona como tarea filosófica venidera esperanzadora. (shrink)

La proporción áurea es señalada por la tradición como un canon de belleza. Este artículo explica el concepto de proporción áurea, empleando como ejemplo la fachada de la capilla de Schönstatt. A continuación se pregunta si hay una base neurológica de la predilección por esta proporción y propone un experimento de magnetoencefalografía para dilucidarlo. Si respeta determinadas condiciones, este experimento puede proporcionar claves más relevantes para este asunto que la medida estética de Birkhoff. Incluso podría cuestionar la opinión de Kant (...) de que el juicio estético es completamente desinteresado. (shrink)

It is estimated that typhoid fever (TF) annually affects more than 12 million persons, worldwide. TF is the result of a generalized infection by the enterobacterium Salmonella typhi. Patients with TF, most of whom live in developing countries have impaired activity for several weeks resulting in an important loss in productivity and welfare. Death may occur, with the single most frequent cause being intestinal perforation. While the first priority must be to develop better methods of disease prevention, there is also (...) an urgent need to devise easy, accurate, and inexpensive diagnostic assays that will allow early routine distinction of TF from other febrile illnesses. Research on TF offers the opportunity to explore many aspects of pathogenesis and the host immune response, as well as to contribute toward the development of new vaccines and diagnostic laboratory tests.

Para analizar el debate entre dos pensadores considerados marxistas, este texto propone situarlos dentro de una tradición filosófica representada por José Ortega y Gasset. Esta tradición recogía de manera original debates filosóficos internacionales y sólo desde la misma puede comprenderse la propuesta de acabar con las Facultades de Filosofía defendida en 1968 por Manuel Sacristán y contestada por Gustavo Bueno. La reconstrucción de dicho debate rescata una reflexión sobre la filosofía, de procedencia orteguiana, que permite respuestas originales al problema (...) de la autonomía de la filosofía y al de la relación con otros saberes. Esa reflexión fue actualizada críticamente en el debate entre ambos autores, aunque hasta ahora ha pasado relativamente desapercibida. (shrink)

Este texto utiliza los análisis sobre la enfermedad mental de Merleau-Ponty para plantearse ciertas preguntas básicas: cuáles son las fronteras entre lo normal y lo patológico, qué tipo de distorsiones introduce la enfermedad mental y en qué ámbitos de la existencia, cómo caracterizar las variaciones de la conducta espaciotemporal a las que nos referimos habitualmente cuando hablamos de enfermedad. Se pone a Merleau-Ponty en diálogo con otros pensadores (señaladamente Erving Goffman) y se articulan sus conceptos respecto de una investigación empírica (...) concreta. (shrink)

En este artículo analizo aportaciones de Michel Foucault y Antoni Domènech, relacionadas ambas con una filosofía política del cuerpo. Para ello estudio sus acercamientos respectivos a la ética clásica, ya sea como una estética de la existencia o como una razón erótica que se opone a una razón inerte. Posteriormente, y tras confirmar sus concomitancias, propongo completarlos con una lectura de El banquete de Platón. Finalmente ejemplifico cómo podría funcionar este programa analizando la conformidad y la resistencia contra la imposición (...) de una ortodoxia corporal. (shrink)

Este texto reconstruye el espacio intelectual en la filosofía durante los años 1940-1950. Distingue tres posiciones, las cuales se irán transformando durante los años 1960 y 1970. El texto define cada posición según sus potencialidades y límites para sobrevivir en el campo de la Filosofía. En diálogo con el libro de Francisco Vázquez intenta comprender qué permaneció y qué cambió en la filosofía española.

The travelling salesman problem (TSP) belongs to the class of NP-hard problems, in which an optimal solution to the problem cannot be obtained within a reasonable computational time for large-sized problems. To address TSP, we propose a hybrid algorithm, called GA-TCTIA-LBSA, in which a genetic algorithm (GA), tour construction and tour improvement algorithms (TCTIAs) and a list-based simulated annealing (LBSA) algorithm are used. The TCTIAs are introduced to generate a first population, and after that, a search is continued with the (...) GA. The problem of premature convergence of the GA to local optimum is tackled by a method called social disaster technique. Afterwards, the LBSA is applied to generate a new population based on one of two proposed operators called packing and judgement day. The proposed algorithm is implemented in the MATLAB environment, and its two variants, called GA-TCTIA-LBSA packing and GA-TCTIA-LBSA judgement day, are tested on symmetric and asymmetric instances from TSPLIB. The overall results demonstrate that the proposed GA-TCTIA-LBSAs offer promising results, particularly for small-sized instances. (shrink)

Philosophers have often argued that ascriptions of content are appropriate only to the personal level states of folk psychology. Against this, this paper defends the view that the familiar propositional attitudes and states defined over them are part of a larger set of cognitive proceses that do not make constitutive reference to concept possession. It does this by showing that states with nonconceptual content exist both in perceptual experience and in subpersonal information-processing systems. What makes these states content-involving is their (...) satisfaction of certain basic conditions deriving from a general account of representation-driven behaviour that is neutral on the question of concept possession. It is also argued that creatures can be in states with nonconceptual content even though they possess no conceptual abilities at all. (shrink)
