El presente trabajo muestra una metodología de análisis de textos en lenguas clásicas desde la perspectiva de una nueva corriente de la ciencia lingüística denominada "etnopragmática", la cual ofrece un abordaje a la vez cualitativo y cuantitativo de los fenómenos sintácticos, de modo tal que constituye una herramienta descriptivamente superadora de anteriores abordajes. Desde este enfoque, la variación posicional del adjetivo en el sintagma nominal latino se interpreta como una estrategia comunicativa motivada por la acción de parámetros contextuales.

"El discipulado pertenece al acontecimiento cristiano: Jesús no existe sin sus discípulos. Desde su resurrección, la Iglesia ha vivido con intensidad el misterio del seguimiento de Cristo, que ya san Pablo relaciona con su imitación. Se trata de un fenómeno central en el NT; pero, dado que abarca toda la persona, su comprensión requiere un acercamiento multidisciplinar: la plenitud bíblica (del AT al NT) se ilumina a partir de sus raíces antropológicas y culturales, y manifiesta sus frutos en la vida del cristiano. El interés por este "misterio del discipulado cristiano", conocido y aún por descubrir, está en el origen del grupo de investigación "Biblia y discipulado", cuyo primer fruto es este volumen."-- Contracubierta.

This article examines the role of the Spanish Atomic Forum as the representative of the nuclear sector in the public arena during the golden years of the nuclear power industry from the 1960s to 1970s. It focuses on the public image concerns of the Spanish nuclear lobby and the subsequent information campaigns launched during the late 1970s to counteract demonstrations by the growing and heterogeneous anti-nuclear movement. The role of advocacy of nuclear energy by the Atomic Forum was similar to that in other countries, but the situation in Spain had some distinguishing features. Anti-nuclear protest in Spain peaked in 1978 paralleling the debates of a new National Energy Plan in Congress, whose first draft had envisaged a massive nuclearization of the country. We show how the approval of the Plan in July 1979, with a significant reduction in the nuclear energy component, was influenced by the anti-nuclear protest movements in Spain. Despite the efforts of the Spanish Atomic Forum to counter its message, the anti-nuclear movement was strengthened by reactions to the Three Mile Island accident in March 1979

El texto presenta los fundamentos filosóficos con los cuales configurar una filosofía latinoamericana que apuntale un proyecto de filosofía de la educación desde la educación popular. Esto se hace a partir del examen de la reflexión filosófica de Leopoldo Zea y Amado Osorio. Para ello, se desarrolla en torno a la presunta existencia de una filosofía latinoamericana, pensamiento filosófico latinoamericano, un presunto acuerdo sobre filosofía, una filosofía de la educación en América Latina y una filosofía de la educación como baluarte de una educación filosófica en América Latina. El texto concluye, además, que una filosofía latinoamericana no tiene por qué tener como condición su ruptura con el pensar del hombre genérico; solo se trata de reconocer sus problemas vitales para aportar claridad reflexiva y actuar sobre ellos con respuestas, incluso, inspiradoras para otros pueblos.

This article seeks to provide a reflection based on philosophy and sociology around the occupation, if any, of the humanities. According to the hermeneutics of founding texts on the question “What is man?” and on various perspectives on it, a reflection is configured that aims to sustain what, in the author's view, corresponds to be the basic and determining occupation of the humanities. For this, five sections will be developed in which an introduction to some basic ideas about the humanities, foundations of a philosophical anthropology, what is man from the study of sociology, what is man from the study of biology and neurosciences, and the humanities as a whole are exposed. The article aims to contribute to the understanding that cultivating the humanities and developing them requires an intention to make them a conceptual and unfinished representation of the world, not a piece of ductile clay in the image and likeness of those who see in them the stage of praxis by excellence. It is mainly concluded that the relevance, the very nature of the humanities, lies in broadening the spectrum of questions about what is man, before attempting to provide complete answers, so that, at the very moment in which the crucial question “What is man?” is found a finished answer and it becomes law, not only is a resolved question left, but also a meaningless life.

This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

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.
