RESUMEN El presente artículo está dirigido a sistematizar una concepción teórica y metodológica que sustente el proceso de extensión universitaria en la carrera de Medicina en Cuba. Entre los resultados se destaca el lugar y papel de la extensión universitaria en el sistema de la formación integral del profesional a la que se asigna una connotación especial, de marcado contenido axiológico, coherente con las necesidades y proyecciones sociales que facilita la formación del educando y fortalece la relación institución-comunidad. Es factible (...) de ser aplicado pues puede devenir en una importante contribución a elevar el impacto social de la docencia médica en tanto atiendan aspectos como la preparación de los implicados en las diferentes instancias; la colaboración de los consejos populares y los factores de la comunidad que se manifiestan en el modo de actuación del profesional. ABSTRACT The present article is directed to systematize a theoretical and methodological conception that sustains the process of university extension in the career of Cuban medicine. Among the results he/she stands out the place and paper of the university extension in the system of the integral formation from the professional to which a special connotation is assigned, of marked axiological contained, coherent with the necessities and social projections that it facilitates the formation of the educating and it strengthens the relationship institution-community. It is feasible of being applied then it can become in an important contribution to elevate the social impact of the medical teaching as long as they assist aspects like the preparation of those implied in the different instances; the collaboration of the popular advice and the factors of the community that are manifested in the way of the professional's performance.

Quienes nos adscribimos al realismo metafísico y tenemos a Robert Spaemann como uno de nuestros filósofos de referencia, celebramos que Comares haya editado una “introducción a la ética de Robert Spaemann”, elaborada por la profesora de la Universidad Católica de Ávila y de la Universidad Pontificia de Salamanca Mª Luisa Pro Velasco (Pro Velasco, 2021). En su introducción, la autora señala que su estudio viene a cubrir el vacío provocado por la escasez de trabajos sobre el filósofo alemán. Y ciertamente (...) lo hace. Por eso, no se trata tanto de un ensayo dirigido a quienes ya conocemos a Spaemann, cuanto de una síntesis orientada a seducir a un público culto de amplio espectro, interesado por la filosofía y cansado de las propuestas éticas idealistas (e ideológicas), para que descubra la obra de este gran filósofo y se adhiera a su idea de que la verdad, por más que sea perspectivista y se deje decir desde múltiples ubicaciones, es siempre verdad y se asienta sobre la realidad. En lo que sigue, ofrecemos una breve recensión del contenido del libro, al objeto de ayudar a los lectores a decidirse en favor de su lectura. (shrink)

This article states that research in skill acquisitionand executionhas underestimated the relevance of some features of attention. We present and theoretically discuss two essential features of attention that have been systematically overlooked in the research of skill acquisitionandexecution. First, attention alters the appearance of the perceived stimuli in an essential way; and second, attention plays a fundamental role in action, being crucial for solving the so called ’many-many problem’, that is to say, the problem of generating a coherent behavior byselecting (...) between many inputs and many potential outputs. We discuss the importance of these features for skill acquisition in sport. We also suggest empirical ways to assess the precise impact of taking them into consideration and at the same time we propose important implications for training derived from the ideas discussed in the paper.

For a standard Finsler F on a manifold M, the domain is the whole tangent bundle T M and the fundamental tensor g is positive-definite. However, in many cases, these two conditions hold in a relaxed form only, namely one has either a psuedo-Finsler metric or a conic Finsler metric. Our aim is twofold. First, we want to give an account of quite a few subtleties that appear under such generalizations, say, for conic pseudo-finsler metrics. Second, we aim to provide (...) some criteria that determine when a pseudo-Finsler metric F obtained as a general homogeneous combination of Finsler metrics and one-forms is again a Finsler-metric -- or, more precisely, that the conic domain on which g remains positive-definite. Such a combination generalizes the known -metrics in different directions. Remarkably, classical examples of Finsler metrics are reobtained and extended, with explicit computations of their fundamental tensors. (shrink)

El objetivo de este artículo es ofrecer una perspectiva histórico-filosófica del idealismo y el Romanticismo. La estrategia que emplearemos en esta investigación consiste en analizar dichas corrientes intelectuales a partir del problema, propio de la Modernidad filosófica, de incorporar la libertad dentro de la estructura de la subjetividad humana. El idealismo y el Romanticismo surgieron gracias a la influencia que ejerció el espíritu libre de la Revolución francesa. El espacio donde se desarrolló esta revolución cultural alemana fue el Círculode Jena, (...) un grupo que concentró a muchos de los intelectuales más influyentes en la historia de la filosofía y la literatura. Y fueron las ideas de Immanuel Kant —en específico, con los temas referentes a la apercepción (Yo pienso), la libertad y el genio— la influencia más determinante para los idealistas y losrománticos.

Los centros penitenciarios poseen módulos educativos donde se procura dotar de enseñanza reglada a los internos para favorecer su reinserción, como se recoge en la Constitución Española de 1978 así como en los decretos de Enseñanza Secundaria para personas adultas. En este marco, se ofrece aquí una propuesta educativa para desarrollar un tema controvertido, como es el del Holocausto, en un ámbito educativo especialmente sensible a procesos educativos en situaciones de confinamiento, un aula de 4º de ESPA en un centro (...) penitenciario, a través del conocimiento de las responsabilidades criminales consideradas en los Juicios de Núremberg. Utilizando la representación dramática como recurso didáctico, ya que los internos tendrían que reproducir los distintos roles de los participantes en los juicios, se pretende, en las diferentes sesiones en las que está estructurada esta propuesta, tratar de las responsabilidades morales, entender la necesaria existencia de unas instituciones fuertes con códigos de convivencia adecuados y desarrollar la empatía con las víctimas del régimen nazi, con el objetivo de que sean desarrollados valores cívicos entre los internos.

Histamine is a multifunctional biogenic amine with relevant roles in intercellular communication, inflammatory processes and highly prevalent pathologies. Histamine biosynthesis depends on a single decarboxylation step, carried out by a PLP-dependent histidine decarboxylase activity (EC 4.1.1.22), an enzyme that still remains to be fully characterized. Nevertheless, during the last few years, important advances have been made in this field, including the generation and validation of the first three-dimensional model of the enzyme, which allows us to revisit previous results and conclusions. (...) This essay provides a comprehensive review of the current knowledge of the structural and functional characteristics of mammalian histidine decarboxylase.

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)

Hace tan solo unos ciento sesenta años que la denominada cultura olmeca salió a la luz. En la historia de la definición de su estilo artístico ocupa un lugar destacado el artista mexicano Miguel Covarrubias. En el artículo realizamos un análisis pormenorizado de su obra, intentando mostrar la evolución de sus ideas artísticas y la importancia que tuvieron a la hora de configurar lo que hoy se denomina «estética olmeca». Se analizan sus presupuestos teóricos y la enorme influencia que (...) sus tesis tienen, aun hoy, a la hora de analizar la que muchos consideran la «cultura madre» de Mesoamérica. (shrink)

Antonio Damasio elabora una teoría de la mente humana y de la conducta moral a partir de su hipótesis sobre la evolución de los mecanismos de autorregulación biológicos. En ella, a la capacidad para representar relaciones organismo-mundo se le confiere un importante papel en los cambios organizacionales que emergen de los sistemas con un sistema nervioso central. Concretamente, en nuestro artículo analizamos, en primer lugar, la tesis acerca de la doble homeostasis biológica- mental que caracteriza a los agentes racionales. Desde (...) su perspectiva, la conciencia es producto y manifestación de complejos procesos del procesamiento de representaciones, los cuales favorecen la regulación no consciente. Además, para entender los procesos conscientes también es clave, según Damasio, conocer cómo la evolución de tales mecanismos está asociada con el desarrollo de áreas neuronales próximas al córtex emocional, especialmente, el giro cingulado. Los argumentos que Damasio utiliza para vincular los procesos representacionales con la particular preocupación humana por los sentimientos de los otros es la segunda cuestión que evaluamos.

The strong political portrait of Eduardo Frei Montalva, the Christian-democratic president of Chile between 1964 and 1970 and, before the violent establishment of general Augusto Pinochet dictatorship regime in 1973, leader of democratic opposition, includes, already in his time, a powerful thought about democracy, rule of law, and global citizenship, and about the origin and meaning of history. And his analysis and proposals retain full political and legal validity.

In a previous essay we demonstrated that quantum mechanical formalism is incompatible with some necessary principles of the mechanism conception still dominant in the physicist’s community. In this paper we show, based on recent empirical evidence in quantum physics, the inevitability of abandoning the old mechanism conception and to construct a new one in which physical reality is seen as a representation which refers to relations established through operations made by us in a world that we are determining. This change (...) is profound and radical, with immediate consequences on both Ontology and Epistemology. This work is our contribution to try to make more concrete how this new conception of the world might be. (shrink)

En este trabajo se define formamente el concepto de representacion en química utilizando homomorfismos desde estructuras algebraicas, que llamamos sistemas de tipo C, en otras estructuras especiales de símbolos muy relacionados con los que son habituales en la qímica experimental. Para la definicion de los sistemas de tipo C se ha seleccionado un conjunto minimo de relaciones y funciones, que son necesarias para expresar proposiciones significativas en química. Tambien se define un lenguaje formal de primer orden adecuado a los sistemas (...) de tipo C, que llamamos L. EI resultado principal que se demuestra es que toda representación que verifica las mismas sentencias de L que un sistema de tipo C, es necesariamente isomorfo a él. Se concluye por lo tanto que puede existir un problema linguístico subyacente en la aplicacion que de la mecaníca cuántica se hace en la química teórica.The concept of representation in chemistry bas been formallv defined by means of homomorphisms from algebraical structures, which we call type-C systems, to some special sets of symbols which can be related to the symbols ordinarily used in experimental chemistry. A minimum number of relations and functions, which would suffice to express significant propositions in chemistry, have been chosen to define type-C systems. A first order formal language L adequate to type-C systems has been defined. It has been shown that each representation that verifies the same sentences of L as a type-C system is necessarily isomorphic to it. It is concluded that a systematic study of the representation problem in chemistry is in order because a deep language problem underlies the application of quantum mechanies to chemical problems.

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two (...) factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.

In this work, the evolution of demographic and health patterns in a Basque rural population from Spain is analysed, as they relate to progress in demographic and epidemiological transition. For this purpose, parochial record data on 13,298 births and 9215 deaths, registered during the 19th and 20th centuries (180090) resulting from cardiovascular diseases and malignant neoplasms (post-transition causes). This last point is in contrast with observations from the first four decades of the 20th century, when infectious diseases and respiratory ailments (...) were determining factors in mortality among this population. The data provided by the study of the variation over time in demographic and health patterns indicate that reducing the risk of mortality is one of the most important preconditions for fertility decline.

The focus of this work is the analysis of changes in completed family size and possible determinants of that size over time, in an attempt to characterize the evolution of reproductive patterns during the demographic transition. With this purpose in mind, time trends are studied in relation to the mean number of live births per family (as an indirect measure of fertility), using family reconstitution techniques to trace the reproductive history of each married woman. The population surveyed is a Spanish (...) rural community called Lanciego, located at the southern end of the province of Alava (Basque Country). A total of 24,510 parish records of baptisms, marriages and burials made between 1800 and 1969 were examined to obtain the demographic data set. For each reconstituted family, the variables included in the study were the number of live births per family or family size (FAMS), year of marriage (YEAR), age at marriage of both partners (AMAN, AWOM), wife’s age at the end of marriage (WEND), duration of marriage (MARD), age at first maternity (A1CH), length of reproductive span (REPS) and number of children dying before their first anniversary (MINF). Through a principal component analysis, three factors were found that explained more than 75% of the total variance. Association of variables in factors I and III was particularly useful in characterizing the variability of mean family size in pre-transitional, transitional and post-transitional cohorts. During demographic transition, a decreasing trend is observed in the variables FAMS, REPS and MINF, while variables AWOM, AMAN, WEND and A1CH show a tendency to increase over the 20th century. Results obtained by multiple regression analysis confirm that the best predictors of family size (dependent variable) were REPS and MINF, which between them explained over 85% of the total variation in FAMS (R2=0·853). In Lanciego, birth control seems to be present on the evidence of an increase in age at first maternity and a decrease in age at last parturition, indicating that the beginning of the reproductive span is delayed and its end is brought forward. Interaction between family size and infant mortality is discussed in the light of various hypotheses, including replacement of descendants, the so-called biological effect and the theory of r and k selection.
