We propose a characterization of mathematical experiments in terms of a setup, a process with an outcome, and an interpretation. Using a broad notion of process, this allows us to consider arithmetic calculations and geometric constructions as components of mathematical experiments. Moreover, we argue that mathematical experiments should be considered within a broader context of an experimental research project. Finally, we present a particular case study of the genesis of a geometric construction to illustrate the experimental use of hand drawings and computers in mathematical practice.

La figura de Roberto Navarrete Troncoso fue parte fundamental del Teatro de la Universidad de Concepción, porque contribuyó desde la escena -como actor, director y dramaturgo- en el desarrollo artístico de un elenco que fue motor importante del crecimiento cultural de la ciudad, pero también del país. El artículo se propone levantar su obra del olvido. Para ello analiza Su día gris desde el comentario dramatológico. Se afirma que la obra está en sintonía con una vertiente de la dramaturgia chilena de comienzos de 1960, en que los dramaturgos escenifican la crisis de la vida y valores de una clase media citadina.

Under an observational, transversal, and descriptive design, the study analyze the degree of adjustment of the perceptions of fear of failure as a mediating variable of the estimated relationship between sporting commitment and the appearance of burnout in young handball players in a competitive context. The sample included a total of 479 youth category handball players selected to compete in the Spanish Regional Championships. The age range was 16 −17 years old. With regard to the years of experience variable, 85.4% stated that they have more than 5 years of experience at the federated handball player level. The Spanish version of Performance Failure Appraisal Inventory, Inventory Athletes Burnout Revised, and Sport Commitment Questionnaire were used to assess fear of failure. The correlation patterns evidence that commitment is negative and significantly associated with emotional exhaustion, depersonalization, and fear of failure and positively associated with reduced sense of personal accomplishment. In the standardized direct effect, negative and significant effects were observed between commitment and fear of failure, fear of failure with emotional exhaustion and depersonalization, and on the contrary, a negative and significant effect was observed between fear of failure and reduced sense of personal accomplishment. The evaluated athletes reflect a positive psychological disposition, show pride in having been selected by their territorial teams and reflect a high desire to show their sporting qualities. Despite the emergence of cognitive-emotional processes associated with fear of failure, this has been observed to protect the sense of self-fulfillment through sport effort, although it also has impacts on further emotional exhaustion and loss of value of sport effort.

Es dentro del marco de la fenomenología de Husserl donde Heidegger lleva a cabo su propuesta filosófica, que implica una “destrucción” o “desmontaje” de los conceptos de la tradición, comenzando por los de la fenomenología de su maestro, y una construcción de su propio proyecto filosófico, basado en una analítica de la existencia.La “destrucción” es prácticamente elevada por Heidegger al rango de método filosófico, en paralelo pero en sentido contrario a la epoché, el método fenomenológico de Husserl. Esta diferencia de método, respecto a una común consideración de la intencionalidad de la conciencia, separa los proyectos fenomenológicos del Husserl de Ideen I y del Heidegger de Sein und Zeit: eidético u ontológico. A partir de su método destructivo Heidegger radicalizará las nociones de la fenomenología de Husserl.Within the framework of the phenomenology of Husserl, Heidegger carries out a double philosophical proposal: the “destruction” or “dismantling” of the concepts from the tradition, beginning with those ones of the phenomenology of his teacher, and the construction of his own philosophical project, based on an analysis of the existence.The “destruction” is practically considered by Heidegger as a philosophical method, which is developed in parallel but in a contrary direction to the phenomenological method of Husserl: the epoché. This methodological difference, applied to the intentionality of the consciousness, that the two philosophers consider, separates the phenomenological projects of Husserl in Ideen I and Heidegger in Sein und Zeit: eidetic or ontological. So and from his destructive method Heidegger is going to radicalize the main notions of the phenomenology of Husserl.

This article aims to clarify facts and contribute reasons that could lead one to consider the possibility of the existence of natural dispositions which, in that case, should be considered as ethical precursors. Given that the neuroethics proposal focuses attention and studies on the human brain in order to carry out the search of those natural dispositions, this text suggest an initial question: is it possible to go beyond the brain in that search? Or even better, before it? In this regard, Baruch Spinoza proposes lines of reflection in his Ethics which appear susceptible to be taken into account and that, interestingly, connect with the recent works of the neuroscientist Antonio Damasio.

This paper claims that phenomenon of empathy, described by Edith Stein, and phenomenon of sympathy, analysed by Max Scheler, offer complementary insights into the essence of intersubjective link and into the conditions of possibility for experiencing the Other. Stein’s and Scheler’s phenomenological analyses took place in the context of Husserlian researches on intersubjectivity problems, following a critical attitude towards modern theories of sympathy and towards Lipps’ psychology of empathy as well. However, Scheler’s and Stein’s standpoints got also together on the basis of a philosophical affinity and a critical shared position with regard to Husserl’s transcendental constitution of phenomenology. According to Stein to empathize involves a particular kind of apperception that actualizes the original contents of living experiences of the alien body in a non-original way, whereas for Scheler to sympathize refers to the manner of feeling with others some shared emotions, in an original way, thanks to inner perception of the living life of the neighbour, as another condition of possibility for the Fremderfahrung.

On many occasions, the maximum result of a team does not equate to the total maximum individual effort of each athlete (social loafing). Athletes often combine their sports life with an academic one (Dual Career), prioritizing one over the over in a difficult balancing act. The aim of this research is to examine the existence of social loafing in a group of novice university rowers and the differences that exist according to sex, academic performance, and the kind of sport previously practiced (individual or team). Therefore, a study was conducted from a probabilistic perspective using the Bayesian Network analysis methodology. The results confirm the existence of the Ringelmann effect or social loafing. The Bayesian analysis let us confirm that having a good student who practices a team sport, even in the individual rowing concept, increases the probability of obtaining greater performance (higher number of strokes and more power in each one). Therefore, when rowing partnerships are formed, the occurrence probability chain is quickly simplified, along with values of the top and bottom variables. Finally, the instantiations undertaken on the bottom variable that appears to be common in the two BNs, the watt input, enhance the results obtained. In short, rowers who have a better academic record are more involved in team testing, so this characteristic is defining when it comes to achieving better performance in team testing.

Background: In an unprecedented situation of interruption of the sporting dynamics, the world of sport is going through a series of adaptations necessary to continue functioning despite coronavirus disease 2019. More than ever, athletes are facing a different challenge, a source of discomfort and uncertainty, and one that absolutely alters not only sports calendars, but also trajectories, progressions, and approaches to sports life. Therefore, it is necessary to identify the levels of psychological vulnerability that may have been generated in the athletes, because of the coexistence with dysfunctional responses during the COVID-19 experience, and which directly influence the decrease of their mental health.Methods: With a descriptive and transversal design, the study aims to identify the state of the dysfunctional psychological response of a sample of Spanish athletes. The DASS-21, Toronto-20, and Distress Tolerance Scale questionnaires were administered to a sample of high-level Spanish athletes in Olympic programs.Results: The results suggest that the analyzed athletes indicate high levels of dysfunctional response when their tolerance is low. In addition, the variables show less relational strength, when the capacity of tolerance to distress is worse and age is lower. At the same time, the greater the anxiety and uncertainty are, leading to more catastrophic and negative thoughts, the younger the athletes are.Conclusions: It is clear that both age and tolerance to distress are considered adequate protective factors for psychological vulnerability in general and for associated dysfunctional responses in particular. Moreover, the psychological resources offered by more experienced athletes are also a guarantee of protection against negativity and catastrophism.

El presente artículo revisa la producción dramática de Deyanira Urzúa de Calvo, escritora chilena de principios de siglo XX. Su soslayada figura es fundamental para comprender el desarrollo del oficio dramaturga, así como las líneas temáticas y formales que caracterizan los años de fundación del teatro chileno y que se mantuvieron en circulación más allá del nacimiento de los teatros universitarios. Se analiza una parte de su larga producción en teatro histórico, comedias y obras para niños/niñas, obras que permiten comprender el desarrollo de la dramaturgia chilena escrita por mujeres y evidenciar procesos continuos de transformación, más que de rupturas románticas.

Este artículo intenta demostrar cómo el aristotelismo hispánico del siglo XIII no puede servisto como un intento por hacer ver la religión inferior a la filosofía, sino más bien como un intento de conciliarfe y razón. Se argüirá que para Averroes, cuyo programa filosófico parece ser un precedente del aristotelismohispánico del siglo XIII, y para los así llamados “filósofos naturales”, encontrar un acuerdo entre religión yfilosofía no era simplemente un ejercicio provechoso, sino más bien un deber del filósofo. De acuerdo con ellos,las discrepancias deben ser resueltas por una lectura alegórica de las Sagradas Escrituras. Tal método permitecorregir inconsistencias y hace del discurso religioso un discurso sólido y convincente en conformidad con larazón. Los pensadores medievales ibéricos se mostrarán no simplemente como lectores pasivos, sino comoacadémicos que propusieron soluciones originales a los problemas planteados por el pensamiento de la época
