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.

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.

Lo que la sociedad contemporánea necesita es integrar la mayor parte de lo que hasta ahora ha sido excluido, ignorado o despreciado. Utilizando la terminología hegeliana podemos decir que el Modernismo formuló una tesis que pretendía ser verdadera. Esa fue la fase afirmativa, que que, sin embargo, era sólo parcial. En consecuencia surgió una antítesis, la que se denomina Postmodernismo. Esta es la fase negativa, que se ha revelado también incompleta. Ahora nos vemos obligados a buscar una síntesis de las (...) dos fases anteriores, la verdad en un nivel superior. (shrink)

RESUMEN La hiperhidrosis primaria, enfermedad crónica por exceso de sudoración, aparece en etapas tempranas de la vida y ocasiona limitaciones que interfieren las relaciones sociales. Esta sintomatología hace que la capacidad de control y tolerancia al estrés sea limitada. Se realizó una investigación descriptiva y se aportan resultados cualitativos individuales de tres jóvenes con hiperhidrosis primaria. Por ello el objetivo del presente trabajo es caracterizar el control y tolerancia al estrés asociados a la hiperhidrosis primaria que presentan tres jóvenes hiperhidróticos. (...) Fueron aplicados una entrevista semiestructurada, el Inventario de Ansiedad Rasgo-Estado y el Sistema Comprehensivo Rorschach. Los resultados son diferentes en los tres jóvenes. Se concluye que las diferencias entre las personas con hiperhidrosis primaria, en relación a su capacidad de control y tolerancia al estrés, están dadas por la combinación característica de elementos que definen la personalidad en estilos y estados en situaciones de demanda social mantenida. ABSTRACT Primary hyperhidrosis, a chronic disease characterized by excessive sweating, appears at an early age and causes limitations that interfere with social relationships. This symptomatology limits the ability to control and tolerate stress. A descriptive research was carried out. It shows the individual qualitative results of three young primary hiperhidrotic people. Therefore, the objective of this paper is to characterize stress control and tolerance associated to primary hyperhidrosis in three young hyperhidrotic people. A semistructured interview as well as the State-Feature Anxiety Inventory and the Rorschach Comprehensive System were used. Results are different in the three young people. It was concluded that differences between people with primary hyperhidrosis, with regard to their ability to control and tolerate stress, lie in the characteristic combination of elements that define the personality in styles and states in sustained social demand situations.

The present article review some implications of the second order research in Social Sciences. Through the concepts of ambivalence, otherness and paradox, challenges that the new paradigm demands to the social researcher are discussed.

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)

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.

There are currently serious concerns that published scientific findings often fail to be reproducible, and that some solutions may be gleaned by attending the several methodological and sociological recommendations that could be found in the literature. However, researchers would also arrive at some answers by considering the advice of the philosophy of science, particularly semantics, about theses on truth related to scientific realism. Sometimes scientists understand the correspondence thesis of truth as asserting that the next unique empirical confirmation of a (...) hypothesis suffices to attribute truth to it provisionally. Such empiricist bias is not necessarily at the core of CTT, but Mario Bunge proposed the synthetic thesis of truth, based on CTT, to explicitly avoid the bias. STT requires considering a hypothesis corroborated, both by purely empirical confirmation and external consistency or compatibility with the bulk of existing background knowledge. While a capricious understanding of CTT could be rigged to recommend the “one shot game” in hypothesis testing, STT clearly demands the use of multiple approaches, empirical as well as theoretical, and it asserts that a scientific test is effective to the extent to which it is neither purely empirical, nor viewed in isolation. Pattern consistency together with an understanding of causal relations make confirmed hypotheses robust and more reliable. The militancy of the double mechanism of hypothesis control of STT can help mitigate the reproducibility crisis. Earl Werner’s research program in community ecology is an example of the use of STT criteria, which leads to the development of reliable, cross-checked, ecological results, with high predictive capacity.

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.

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.

According to logical non-necessitarianism, every inference may fail in some situation. In his defense of logical monism, Graham Priest has put forward an argument against non-necessitarianism based on the meaning of connectives. According to him, as long as the meanings of connectives are fixed, some inferences have to hold in all situations. Hence, in order to accept the non-necessitarianist thesis one would have to dispose arbitrarily of those meanings. I want to show here that non-necessitarianism can stand, without disposing arbitrarily (...) of the meanings of connectives, based on a minimalist view on the meanings of connectives. (shrink)

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.

La crisis ambiental está en el centro de la crisis económica y social que tenemos y, en consecuencia, los próximos cambios que vamos a vivir estarán marcados fundamentalmente por nuestras formas de relacionarnos con el entorno. De ahí surge la necesidad de concebir la sostenibilidad como bien común desde la perspectiva de nuestra dependencia de la naturaleza y la necesidad de preservarla, y desde las limitaciones de la gestión privada.

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.

En este trabajo se estudia la lectura hermenéutica de la obra freudiana que propusieron pensadores como Habermas o Ricoeur, y su continuación en el llamado "psicoanálisis narrativo", no sólo desde el punto de vista epistemológico sino también como una importante contribución a la discusión sobre la identidad personal.

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.

The intention of this paper is crossed by a double view. First, reread from an existential point of view, some considerations about corporeality and intersubjectivity, as studied by G. Marcel, and second, reflect, from a phenomenological approach, projections and relationships between these intuitions and the world of biology, and specifically, cognitive science.

In this paper I probe the idea that neither possibilism nor trivialism could be ruled out on a purely logical basis. I use the apparatus of relational structures used in the semantics for modal logics to engineer some models of possibilism and trivialism and I discuss a philosophical stance about logic, truth values and the meaning of connectives underlying such analysis.

However broad or vague the notion of connexivity may be, it seems to be similar to the notion of relevance even when relevance and connexive logics have been shown to be incompatible to one another. Relevance logics can be examined by suggesting syntactic relevance principles and inspecting if the theorems of a logic abide to them. In this paper we want to suggest that a similar strategy can be employed with connexive logics. To do so, we will suggest some properties (...) that seem to be hinted at in Nelson’s work. Following this strategy will ideally shed some light over the notion of content and will also help make a clear comparison between relevance and connexive logics. (shrink)

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].

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.

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)

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.
