En las páginas que siguen, vamos a realizar una lectura política del pensamiento de Derrida, dirigiendo nuestra atención, primero, a la deconstrucción de la escritura para centrarnos en el significado político de la différance , segundo, a la institución filosófica como vehículo de elaboración y transmisión del saber y, tercero, a lo que el pensador francés ha reunido bajo el rótulo figuras de lo imposible , con especial atención a la hospitalidad, la responsabilidad y la justicia.

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Fundamento: El currículo de estudios, principalmente de posgrado, no puede considerarse como un plan al que hay que ajustarse de manera estricta, sino que debe ser más flexible, que dé salida a los objetivos propuestos según las situaciones del entorno. Objetivo: mostrar algunos resultados de la vinculación del residente de Higiene y Epidemiología a actividades epidemiológicas emergentes en la actualidad. Método: se realizó un estudio descriptivo transversal en el Centro Provincial de Higiene, Epidemiología y Microbiología de Camagüey durante junio de (...) 2014. Se entrevistó a un universo de 32 profesionales. Las variables utilizadas fueron: utilidad de la vinculación extracurricular a programas y tareas de control epidemiológico, desarrollo práctico de los aspectos teóricos, vencimiento con calidad del diseño curricular de la residencia y si se consideró necesario o no interrumpir el plan de estudios ante eventos epidemiológicos de emergencia. Resultados: La mayoría de los especialistas consideró que la vinculación a actividades específicas le permitió vencer con calidad el plan de estudios, mientras que el mayor porcentaje de los residentes no lo estimó así. Ningún residente entrevistado estuvo de acuerdo con la interrupción del plan de estudios ante situaciones emergentes. Conclusiones: la vinculación del residente a actividades prácticas emergentes puede servir de incentivo para la graduación de un especialista con mayor competencia profesional, sin abandonar el diseño curricular establecido. Fundament: The study curriculum, especially of post grade, cannot be considered as a plan to which one has to be adjusted in a strict way, but to be more flexible, offering a way out to the proposed objectives according to the situations of the environment. Objective: to offer some results of the linking of the medical resident of Hygiene and Epidemiology to emergent epidemiological activities at the present time. Method: A cross-sectional descriptive study at the Provincial Center of Hygiene, Epidemiology and Microbiology during June 2014 was carried out. A universe of 32 professionals was interviewed. The variables used were: usefulness of the extracurricular linking to programs and tasks of epidemiological control, practical development of theoretical aspects, quality achievement of the curricular design of the medical residency, and if it was necessary or not to interrupt the study plan in emergent epidemiological events. Results: Most of the specialists considered the linking to emergent epidemiological activities allowed to finish with quality its study plan, while that the biggest percentage of the residents did not estimate it in the same way. None of the interviewed resident agreed with the interruption of the study plan in front of emergent situations. Conclusions: the linking of the medical resident to practical emergent activities can serve as incentive for the graduation of the specialists with better professional competence without abandoning the established curricular design.

El presente artículo tiene como misión demostrar cómo la poesía mexicana, en especial la de los años sesenta, trabajó no únicamente el problema de la identidad, sino, además, cómo se apropió del giro lingüístico en su estructura para responder a dicha pregunta; todo ello enmarcado bajo el concepto histórico de lo moderno. Para ello, primero se abordará la redefinición de la literatura mexicana tras la Revolución de 1910; después, se abordará la idea de Octavio Paz sobre modernidad y su relación (...) con la poesía como un aparato crítico; y, al final, la exposición de los poemas de Ulalume González de León, para ahondar en cómo cuestiona y define el lenguaje y la identidad en su obra poética de 1968 y 1969.

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.

The authors present some remarks on Al- Farabi's reception and understanding of Platonic Dialogues, especially according to "The Philosophy of Plato". In this treatise, Al- Farabi intends to show how politics were meant to be the leitmotiv of Plato's writings. He also discusses the argumentative and cognitive relations that exist between Political Science, Philosophy and Religion. As the statesman is engaged in pedagogical functions, he is urged to have some discursive abilities —besides the speculative knowledge of the first principles— for (...) him to incite the multitude to act.

Aprender de los griegos es posible, pero solo si partimos de dos bases necesarias: la primera, que nuestro mundo es profundamente distinto al suyo; la segunda, que el pensamiento libre requiere no quedar prisionero de ningún dogma. La forma primitiva de pensar de los griegos es una escuela que nos puede ayudar a desnudar la enorme cantidad de supuestos en los que se apoya la mentalidad contemporánea.

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

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.

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.

For several decades, tourism has mainly been identified as an activity that helps people escape their everyday routines, contributes to understanding between cultures, and promotes economic wellbeing. These assumptions have been questioned in both the public sphere and academic research, however. In this context, tourism research is increasingly drawing on ethical frameworks to support its criticism of tourism. Some of the most outstanding research on this issue is by Dean MacCannell, Emeritus Professor at the University of California at Davis and (...) author of one of the seminal works of the social theory of tourism: The Tourist: A New Theory of the Leisure Class (1976). MacCannell examines the moral and ethical aspects of tourism in all his writing, but they are the focal point of his book The Ethics of Sightseeing (2011), in which he identifies the tourists’ responsibility to mediate between their understanding of their own pleasure and the ethical repercussions of the late modern imperative, “Enjoy!”. During the Touriscape congress in Malaga, Spain, in February 2018, MacCannell talked about ethics and tourism with José Luis López, who prepared this interview for Recerca. (shrink)

PurposeGraham Priest has recently argued that the distinctive trait of classical mathematics is that the conditional of its underlying logic—that is, classical logic—is extensional. In this article, I aim to present an alternate explanation of the specificity of classical mathematics.MethodI examine Priest's argument for his claim and show its shortcomings. Then I deploy a model-theoretic presentation of logics that allows comparing them, and the mathematics based on them, more fine-grainedly.ResultsSuch a model-theoretic presentation of logics suggests that the specific character of (...) classical logic consists in the structure that it confers to its truth values and in the structure of the evaluation indices of its formulas, and that this trait is useful to explain the specific character of the logics and the mathematics based on them.ConclusionThe extensionality of the conditional in classical logic is a by-product of other structural features of a logic, which are more likely to be what gives a kind of mathematics based on it its specific character.

A critical review of the crucial Freudian change in the general explanation of hysterics and neurosis that took place in 1897 would not let us assess in a definite way the epistemic import of Psychoanalysis. However some difficulties that appear in Freud’s works, related for instance to the no-contradiction principle, demand that we make an epistemic and a moral decision. But only if we wanted to maintain the critical attitude that modern science and philosophy have brought to us, a decision (...) that would allow us to see Freudianism as a faith and as “a testimony of a man in our age”.

In this paper we show that, when analyzed with contemporary tools in logic—such as Dunn-style semantics, Reichenbach’s three-valued logic exhibits many interesting features, and even new responses to some of the old objections to it can be attempted. Also, we establish some connections between Reichenbach’s three-valued logic and some contra-classical logics.

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.

In this paper we discuss whether the relation between formulas in the relating model can be directly introduced into the language of relating logic, and present some stances on that problem. Other questions in the vicinity, such as what kind of functor would be the incorporated relation, or whether the direct incorporation of the relation into the language of relating logic is really needed, will also be addressed.

Modal concepts (possibility, existence, necessity, contingency) acquire a capital relevance in Leibniz´s metaphysic, to such an extent that the whole set of particularities of his philosophical doctrines can be explained with a reference to the mentioned modal concepts.

For the sake of universalism and against totalitarianism, discursive ethics has shown with Jürgen Habermas a practical deficit by denying moral philosophy the possibility of reflecting on the alienating conditions for dialogue through a specific ethos.

A partir de la distinción entre culto genéricamente religioso y culto cristiano se reflexiona sobre la novedad de la Liturgia cristiana, en cuya naturaleza pesa más la dimensión descendente, o sea, su cualidad de ser actualización, aquí y hoy, del Misterio de Cristo que la dimensión cultual o ascendente, o sea la glorificación de Dios.

Beall has given more or less convincing arguments to the effect that neither classical logic, nor K3, nor LP, nor S3 can play the role he expects from logic: to be the basement theory for all true theories, including true theology. However, he has not considered all the pertinent competitors, and he has not given any reassurance that he has not gone too low in the hierarchy of logics to find his desired “universal closure of all true theories”. In this (...) paper, I put forward those additional arguments to show the superiority of FDE with respect to logics that include a detachable conditional but that are very much like FDE otherwise. I also discuss the problem that theological consequence might not contrapose even if theological consequence is supposed to extend FDE consequence and the latter does contrapose. (shrink)
