En este trabajo se estudia “Nocturno del hueco” (Poeta en Nueva York, 1929) de Federico García Lorca, a partir de un acercamiento al modo en que se construye el ‘hueco’ en la voz poética. Se intenta explicar cómo y por qué García Lorca usa imágenes relacionadas con el mundo natural (plantas, animales y los cuatro elementos). Primero, se observa cómo usa los sentidos el poeta: existe una estrecha relación entre los sentidos y la manera en que aparecen los elementos naturales. (...) Los sentidos determinan la interpretación que uno puede tener de los elementos naturales: la significación de estos está condicionada por una presencia o ausencia que se advierte sólo por ellos. Igualmente, se intuye que el vacío que habita al yo poético se ensancha hasta rozar la muerte. Palabras clave: nocturno, vacío, sentidos, elementos naturales, amor y muerte. (shrink)

Seen from the point of view of evaluation conditions, a usual way to obtain a connexive logic is to take a well-known negation, for example, Boolean negation or de Morgan negation, and then assign special properties to the conditional to validate Aristotle’s and Boethius’ Theses. Nonetheless, another theoretical possibility is to have the extensional or the material conditional and then assign special properties to the negation to validate the theses. In this paper we examine that possibility, not sufficiently explored in (...) the connexive literature yet.We offer a characterization of connexive negation disentangled from the cancellation account of negation, a previous attempt to define connexivity on top of a distinctive negation. We also discuss an ancient view on connexive logics, according to which a valid implication is one where the negation of the consequent is incompatible with the antecedent, and discuss the role of our idea of connexive negation for this kind of view.

Francez has suggested that connexivity can be predicated of connectives other than the conditional, in particular conjunction and disjunction. Since connexivity is not any connection between antecedents and consequents—there might be other connections among them, such as relevance—, my question here is whether Francez’s conjunction and disjunction can properly be called ‘connexive’. I analyze three ways in which those connectives may somehow inherit connexivity from the conditional by standing in certain relations to it. I will show that Francez’s connectives fail (...) all these three ways, and that even other connectives obtained by following more closely Wansing’s method to get a connexive conditional, fail to be connexive as well.

A contra-classical logic is a logic that, over the same language as that of classical logic, validates arguments that are not classically valid. In this paper I investigate whether there is a single, non-trivial logic that exhibits many features of already known contra-classical logics. I show that Mortensen’s three-valued connexive logic _M3V_ is one such logic and, furthermore, that following the example in building _M3V_, that is, putting a suitable conditional on top of the \(\{\sim, \wedge, \vee \}\) -fragment of (...) _LP_, one can get a logic exhibiting even more contra-classical features.

Alberic of Paris put forward an argument, ‘the most embarrassing of all twelfth-century arguments’ according to Christopher Martin, which shows that the connexive principles contradict some other logical principles that have become deeply entrenched in our most widely accepted logical theories. Building upon some of Everett Nelson’s ideas, we will show that the steps in Alberic of Paris’ argument that should be rejected are precisely the ones that presuppose the validity of schemas that are nowadays taken as some of the (...) most trivial logical truths: (A∧B) → A and (A∧B) → B, i.e. Simplification.

Mortensen studies dual intuitionistic logic by dualizing topos internal logic, but he did not study a sequent calculus. In this paper I present a sequent calculus for complement-topos logic, which throws some light on the problem of giving a dualization for LJ.

BackgroundMoral distress (MD) is the psychological damage caused when people are forced to witness or carry out actions which go against their fundamental moral values. The main objective was to evaluate the prevalence and predictive factors associated with MD among health professionals during the pandemic and to determine its causes.MethodsA regional, observational and cross-sectional study in a sample of 566 professionals from the Public Health Service of Andalusia (68.7% female; 66.9% physicians) who completed the MMD-HP-SPA scale to determine the level (...) of MD (0-432 points). Five dimensions were used: i) Health care; ii) Therapeutic obstinacy-futility, iii) Interpersonal relations of the Healthcare Team, iv) External pressure; v) Covering up of medical malpractice.ResultsThe mean level of MD was 127.3 (SD=66.7; 95% CI 121.8-132.8), being higher in female (135 vs. 110.3; p<0.01), in nursing professionals (137.8 vs. 122; p<0.01) and in the community setting (136.2 vs. 118.3; p<0.001), with these variables showing statistical significance in the multiple linear regression model (p<0.001; r2=0.052). With similar results, the multiple logistic regression model showed being female was a higher risk factor (OR=2.27; 95% CI 1.5-3.4; p<0.001). 70% of the sources of MD belonged to the dimension "Health Care" and the cause "Having to attend to more patients than I can safely attend to" obtained the highest average value (Mean=9.8; SD=4.9).ConclusionsFemale, nursing professionals, and those from the community setting presented a higher risk of MD. The healthcare model needs to implement an ethical approach to public health issues to alleviate MD among its professionals. (shrink)

En The paradox of Addition and its dissolution (1969), Mario Bunge presenta algunos argumentos para mostrar que la Regla de Adición puede ocasionar paradojas o problemas semánticos. Posteriormente, Margáin (1972) y Robles (1976) mostraron que las afirmaciones de Bunge son insostenibles, al menos desde el punto de vista de la lógica clásica. Aunque estamos de acuerdo con las críticas de Margáin y Robles, no estamos de acuerdo en el diagnóstico del origen del problema y tampoco con la manera en la (...) que se proponen solucionarlo. En esta medida, en este texto mostraremos cómo la Regla de Adición sí trae problemas semánticos que pueden ser planteados desde diferentes perspectivas contemporáneas, como la extensionalidad del condicional, los principios proscriptivos y la validez conexiva.

Here we study two connexive logics based on one of the conditionals introduced by Church in [4] and on some negations defined through falsity constants in the sense of Ackermann in [1].

En el contexto del cambio de una concepcion sustancialista a una concepcion desustancialista, en la cual se pierde de vista el fundamento mismo de la persona, el autor de este estudio cree que el problema de la identidad humana exige un replanteamiento y una reconstruccion. Es preciso entonces emprender un camino que conduzca a reconstruir al hombre, sacandolo del anonimato nihilista en el que lo habia sumido la modernidad al exagerar indebidamente el intelectualismo de la filosofia tradicional precedente. La antropologia (...) actual podra reivindicar la autenticidad de la propia persona y el verdadero alcance de la libertad humana en su configuracion.

In this paper, we provide a set-theoretic proof of the general representation theorem for MV-algebras, which was developed by Dubuc and Poveda in 2010. The theorem states that every MV-algebra is isomorphic to the MV-algebra of all global sections of its prime spectrum. We avoid using topos theory and instead rely on basic concepts from MV-algebras, topology and set theory.

Introducción: los accidentes son de las primeras causas de muerte a nivel mundial, por lo que la prevención de los mismos es una emergencia. Objetivo: valorar la repercusión de una intervención comunitaria en la disminución de peligros potenciales de accidentes en familias con niños de 0 a 18 meses. Métodos: se realizó un estudio cuasi experimental multietápico, con enfoques cuantitativo y cualitativo, entre enero de 2009 a junio de 2012. Se trabajó con 39 familias entre las que se produjeron nacimientos (...) en el periodo enero de 2008 a enero de 2010 de los Consultorios Médicos del Consejo Popular 26 de julio del Municipio Santo Domingo. Se efectuó una intervención por un grupo de trabajo comunitario conformado por integrantes del Círculo de interés "Prevención es Salud" y brigadistas de la Cruz Roja, liderados por la enfermera de la familia, se empleó para ello la Guía para Análisis de vulnerabilidades y capacidades de la Cruz Roja, modificada en su etapa I. Resultados: Post intervención se logró la reversión de vulnerabilidades en cuanto a capacidades, se manifestaron cambios favorables en los conocimientos y disminuyó significativamente el número de peligros potenciales en cada hogar. Conclusiones: Cuando se trabaja con familias con instrumentos sencillos y accesibles, y con el grupo de trabajo comunitario, se favorece la toma de conciencia sobre el problema en el entorno donde se generó. Introduction: accidents are one of the first causes of death worldwide, so their prevention is an urgency. Objective: assess the effect of a community intervention in the reduction of potential dangers of accidents in family with children aged from zero to 18 months. Methods: a multiage cuasi experimental study was carried out, with quantitative and qualitative approaches, from January 2009 to June 2012. The sample was taken from thirty-nine families who had children in the period ranging from January 2008 to January 2010 belonging to the family doctor´s house of the community called "26 de Julio" from Santo Domingo municipality. An intervention was carried out by a community group work composed by members of centers of interests called ¨Prevention is health¨ and members of the Red Cross led by the family nurse. It was necessary to ask a guide to analyze the vulnerabilities and capabilities of the Red Cross, modified in the first stage. Results: During the post intervention, it was possible to change the vulnerabilities in terms of capacities, favorable changes were present in the knowledge and the number of potential risks significantly decreased in each house. Conclusions: when families are approached with simple and accessible instruments, and with a community group work it is possible to make favorable changes in terms of awareness of the problem in the same place where it emerged.

Apoyado en un análisis filológico, este artículo busca interpreta la intertextualidad de “El Ojo Silva” como elemento clave de una ética inmanente que gira en torno a la violencia. La intertextualidad sirve tanto para posicionar el cuento dentro de una tradición literaria acéfala y de largo aliento, como para plantear que las iteraciones narrativas nutridas por la imaginación representan un ejercicio de la razón práctica que abarca generalizaciones, historia y ficción. La argumentación está dividida en cuatro partes que entrelazan: el (...) planteamiento de un caso por medio de la captatio benevolentiae de la retórica clásica, el exilio como experiencia histórica y alegoría, el evento violento como centro inmanente y la violencia soberana que perfila una poética de la excepción. Este derrotero comienza con un rasgo estilístico puntual para fundamentar las reflexiones teóricas sobre la narrativa corta en la modernidad que cierran la investigación. (shrink)

Comparative study of the knowledge of IVF in medical students of universities with different ethical and humanistic valuesEstudo comparativo do conhecimento das técnicas de reprodução assistida em estudantes de Medicina de universidades com diferentes ideários éticos e humanísticosIn vitro fertilization continues to be presented as a relatively simple solution to produce a pregnancy without exposing the medical and ethical problems that this represents. This project consisted of conducting a survey to medical students from three medical schools in Mexico City with (...) different ethical and humanistic ideas with the aim of evaluating knowledge about IVF techniques and their ethical implications. The survey was applied to 404 medical students. Students in schools with personalistic ethics had a greater recognition of the bioethical principles involved in the use of these techniques. Knowledge of the technique and ethical issues involved in assisted reproduction could improve the sensitivity of medical students to ethical dilemmas that arise in their professional practice.Para citar este artículo / To reference this article / Para citar este artigoCantú-Quintanilla G, Vidal-Sentíes C, Marcó-Bach FJ, Camargo-Prieto F, Aguiñaga-Chiñas N, Contreras-Estrada D.
