Las 15 piezas que ahora lo conforman abrevan en la Historia, en confeciones personales y entrevistas, y mezclan la literatura y el periodismo de manera audaz y perfecta. Los protagonistas son hombres excepcionales y el momento que se ha elegido para contar son las visperas de sus muertes -tal vez el momento de mayor soledad y de mayor intimidad de un hombre. A traves de la magistral escritura de Tomas Eloy Martinez tenemos el privilegio de asistir a los ultimos (...) minutos de sus vidas, el momento previo a perderlo todo y cuando, resistiendo a la indiferencia del mundo, se suena con alguna inmortalidad.

In his Trauerspiel study, Benjamin analyses the role of the baroque allegorist in an age in which his word is the expression of the melancholic gaze of an abandoned subject handed over to an absolute immanence. But the allegorist makes a move through which he achieves to go from immanence to God, allegorizing the concept of evil that he himself has produced. Even when he meets the characteristics of those allegorists, Baltasar Gracian does not make, in our judgement, this kind (...) of betrayal to his own logos, surrendering completely to the consequences of natural history, the immanence and the allegorical saying.

In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)

The lockdown resulting from coronavirus disease 2019 has had a huge impact on peoples’ health. In sport specifically, athletes have had to deal with frustration of their objectives and changes in their usual training routines. The challenging and disruptive situation could hold implications for their well-being. This study examined the effect of the COVID-19 lockdown on changes in athletes’ reported eudaimonic well-being and goal motives over time. The relationship of resilience to changes in subjective vitality was also determined, and changes (...) in athletes’ goal motives were examined as potential mediators. Participants were 127 Spanish university athletes aged between 18 and 34 years. Approximately 4 months before the start of the lockdown in Spain, athletes responded to a questionnaire assessing their resilience, goal motives, and subjective vitality. Around 6 months later into the lockdown period, athletes’ goal motives and subjective vitality were assessed again. Growth modeling using hierarchical linear models revealed a significant decrease of autonomous goal motives and subjective vitality during the lockdown, but athletes did not show change over time in controlled goal motives. Path analysis, adjusting T2 measures for their corresponding T1 measures, showed that resilience significantly predicted changes in athletes’ autonomous goal motives, which then accounted for changes in subjective vitality. The indirect effect was significant. Resilience did not predict changes in athletes’ controlled goal motives. However, changes in controlled goal motives negatively predicted changes in subjective vitality during lockdown. The findings suggest negative impacts of the COVID-19 lockdown on athletes’ goal motives and eudaimonic well-being. Results also support the hypothesized mediational role of autonomous goal motives in the relationship between resilience and subjective vitality during the lockdown. As such, findings confirm the relevance of resilience to a key feature of athletes’ eudaimonic well-being and the importance of enhancing their autonomous goal striving. (shrink)

To achieve their goals, organizations for individuals with intellectual disability have to stimulate high-quality relationships between professionals and family members. Therefore, achieving professionals’ trust in family members has become a challenge. One relevant factor in explaining professional’s trust in families is the degree to which family members use the “problem-solving” conflict management strategy in their disputes–disagreements with professionals. It is reasonable to argue that when family members use problem-solving conflict management, professionals’ trust increases. Professionals’ trust, in turn, stimulates the use (...) of problem-solving strategies by family members. However, it is also plausible that professionals are the initiators of this positive spiral. To examine this relationship between problem solving and trust over time, we conducted a longitudinal survey study in which 329 professionals reported on these two constructs three times. Using structural equation modeling, we compared four nested models: stability, causality, reversed causation, and reciprocal. The results of the χ2 difference tests, regarding the comparison of the models, showed that the reciprocal model was significantly superior to the alternative proposals. Our findings supported a complex view of the relationships between problem-solving conflict management and trust, based on dynamic reciprocal relationships over time. (shrink)

The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness. Therefore, it is necessary to measure and monitoring the levels of PA in childhood and adolescence, since it may be useful to describe their current health status and the association with physical fitness, as well as to reveal putative consequences in the future. Within the educational field, it has been shown (...) that physical education (PE) classes are a favorable context for the creation of healthy physical-sports habits and self-determined motivation could be a key for explaining the level of PA practice. For this reason, the purpose of this research was to study the mediating role of integrated regulation (IR) on the relationship between PA and physical fitness in children and adolescents. A total of 325 students between 11 and 14 years old participated in the study. The level of PA was estimated through the specific Physical Activity Questionnaire for Children (PAQ-C), while motivation and IR were measured by using the Perceived Locus of Causality scale (PLOC-2). In addition, physical fitness was measured through the Eurofit fitness battery of tests, composed of three body composition measures and seven tests of different physical capacities. The physical fitness score showed no differences when genders were compared. After regression analysis, the resulti... (shrink)

Resumen: La “visión escotópica” desarrollada por Aristóteles en De Anima II 7 es la primera formulación sistemática de este fenómeno clave para las actuales neurociencias. En la teoría aristotélica surge una aparente contradicción entre el “compromiso ontológico” de la oscuridad como privación y el “realismo gnoseológico” que considera visible esa misma oscuridad. Tomás de Aquino en su Sententia libri De Anima propone una interpretación que establece la relación analógica entre luz y oscuridad a través del color. Esta estrategia permite disolver (...) cualquier contrariedad y establecer una percepción visual de la oscuridad en sentido realista.: The “scotopic vision” developed by Aristotle in De Anima II 7 is the first systematic formulation of this key phenomenon for current neurosciences. In this theory an apparent contradiction arises between the “ontological commitment” of darkness as deprivation and the “gnoseological realism” that considers that same darkness visible. Tomás de Aquino in his Sententia libri De Anima proposes an interpretation that establishes the analogical relationship between light and darkness through color.

El conocimiento y la enseñanza de la verdad están profundamente arraigados en la autoconciencia, y así ha sido reconocido en numerosos momentos de la historia de la Filosofía y la Teología desde que fuera grabada en el templo de Apolo, en Delfos, la exhortación Conócete a ti mismo. En este estudio se intenta mostrar la estrecha vinculación entre la autoconciencia y el orden docente en el pensamiento de Santo Tomás de Aquino, quien no sólo destaca por su doctrina acerca del (...) hombre sino también por su profunda pedagogía.

Os prólogos dos comentários de Tomás de Aquino às obras de Aristóteles são de suma importância, porque neles o autor apresenta o que se poderia denominar “o marco conceptual” do trabalho que está empreendendo. No caso do Comentário à Política, o conceito fundamental é o conceito de natureza. A afirmação de que existe uma “imitação da natureza” significa, para Tomás, muito mais do que representou para seus antecessores. PALAVRAS-CHAVE – Tomás de Aquino. Comentário. Política. Natureza. Imitação. ABSTRACT The prologs of (...) Thomas Aquinas to the works of Aristotle are of main importance, because in these prologs the author presents what could be called “the conceptual mark” of the tasks he is undertaking. In the case of the Comments to the Politics, the fundamental concept is the concept of nature. The statement that there is an “imitation of nature” means, for Thomas, much more that it had represented for his antecessors. KEY WORDS – Thomas Aquinas. Comment. Politics. Nature. Imitatio.

Este trabajo muestra la percepción de la población humana asentada en las siete áreas naturales protegidas federales de Baja California Sur, desde el punto de vista del conocimiento empírico sobre los cambios en el medio ambiente y recursos naturales ante efectos del Cambio Climático (CC). Se recolectaron datos a partir de la aplicación de 250 encuestas cualitativas en 2011. Los resultados muestran que la mayor parte de la población conoce el significado de CC y que los efectos que perciben son (...) reducción en la superficie forestal por cambio en uso de suelos, reducción de la actividad pesquera por cambios en las condiciones del mar, efectos negativos en el hato ganadero y frecuencia e intensidad de huracanes, aumento en sequías, falta de agua y reducción en la actividad ecoturística por cambios en las playas. Estudios han demostrado que la valoración subjetiva de la población humana contribuye a cambios en el comportamiento mediante una estrategia de adaptación y toma de conciencia del ciudadano.

In Aristotle’s system there is an important ambiguity between his religious positions or, if they could be so called, his religious ideas, and his theological thought. The first aspect makes room to popular beliefs and can be seen in some philosophically unimportant documents like his will, but also in some philosophically relevant writings like his Metaphysics and his treatise On The Heavens. The second aspect, his theological position, is in flagrant opposition to the first one. On the contrary, in Aquinas (...) there is no contradiction between the object of faith in religion and his theological thought. Furthermore, religion entails ethical duties which can entirely be justified theologically, which is not the case with Aristotle. Natural law is the main concept that links the religious with the theological level in his thought. (shrink)

RESUMEN: Una tendencia importante en la filosofía de la educación contemporánea toma de la sociología del conocimiento la manera de entender la naturaleza del conocimiento científico. Esta tendencia parte de una crítica al "cognitivismo" individualista, asociado con una concepción tradicional del conocimiento y defiende una posición consensualista según la cual el conocimiento es la búsqueda de consenso. El objetivo del trabajo es mostrar que los consensualistas asumen una falsa dicotomía. Contrario a lo que los consensualistas asumen la cognición puede entenderse (...) a la vez como un logro social y como el resultado del ejercicio de capacidades individuals. Concluyo haciendo ver algunas consecuencias del abandono de esa dicotomía para entenderel papel de la autoridad en la educación.ABSTRACT: An important trend in contemporary philosophy of education follows a view of knowledge promoted by sociologists of knowledge. According to this view a critique of the cognitive individualism implicit in the traditional account of knowledge leads to "consensualism ", the view that knowledge is the search for consensus. The aim of this paper is to show that the consensualists assume a false dichotomy. Cognition can be understood both as a social achievement and as the display of individual capacities. I conclude by exploring some consequences of the abandoning of this dichotomy for our understanding of the role of authority in education. (shrink)

As opposed to the criticism expressed by some personalists regarding the metaphysics of the person of Saint Thomas de Aquinas, this text proposes that the incommunicability of the personal being is not only a thesis against interpersonal communication but also its fundamental basis.
