El texto plantea la importancia del oikos griego en tanto referente simbólico que puede permitir, en condiciones de adversidad, la construcción de una estética de la existencia que se constituya en una opción para seguir viviendo cuando las condiciones son desfavorables para la existencia de la vida y para la vivencia del hogar, es decir, en escenarios de conflicto como los que actualmente viven muchas personas en condición de refugiados, de inmigrantes, de asilados; así también quienes están secuestrados y aquellos (...) que viven el desplazamiento forzado y ambiental. Tomaremos como referente de la adversidad lo sucedido en el campo de concentración de Auschwitz para relacionar aquellos hechos de crueldad con muchas de las situaciones que acontecen hoy en el panorama global. Todo esto con la idea de proponer la vivencia del oikos como una construcción íntima que manifiesta la vida y que puede convertirse en un refugio en circunstancias difíciles. (shrink)

The compact and, with \ M\, very massive object located at the center of the Milky Way is currently the very best candidate for a supermassive black hole in our immediate vicinity. The strongest evidence for this is provided by measurements of stellar orbits, variable X-ray emission, and strongly variable polarized near-infrared emission from the location of the radio source Sagittarius A* in the middle of the central stellar cluster. Simultaneous near-infrared and X-ray observations of SgrA* have revealed insights into (...) the emission mechanisms responsible for the powerful near-infrared and X-ray flares from within a few tens to one hundred Schwarzschild radii of such a putative SMBH. If SgrA* is indeed a SMBH it will, in projection onto the sky, have the largest event horizon and will certainly be the first and most important target for very long baseline interferometry observations currently being prepared by the event horizon telescope. These observations in combination with the infrared interferometry experiment GRAVITY at the very large telescope interferometer and other experiments across the electromagnetic spectrum might yield proof for the presence of a black hole at the center of the Milky Way. The large body of evidence continues to discriminate the identification of SgrA* as a SMBH from alternative possibilities. It is, however, unclear when the ever mounting evidence for SgrA* being associated with a SMBH will suffice as a convincing proof. Additional compelling evidence may come from future gravitational wave observatories. This manuscript reviews the observational facts, theoretical grounds and conceptual aspects for the case of SgrA* being a black hole. We treat theory and observations in the framework of the philosophical discussions about “realism and underdetermination”, as this line of arguments allows us to describe the situation in observational astrophysics with respect to supermassive black holes. Questions concerning the existence of supermassive black holes and in particular SgrA* are discussed using causation as an indispensable element. We show that the results of our investigation are convincingly mapped out by this combination of concepts. (shrink)

El Patronato de Misiones Pedagógicas desarrolló una importante labor de recuperación y difusión de la cultura musical, especialmente del folklore musical español, en los primeros años de la II República española, al poner en marcha un servicio de música y un coro que se encargaron de acercar diferentes estilos y géneros musicales a los habitantes de las zonas rurales más deprimidas. En este artículo se presenta un estudio documental sobre el trabajo llevado a cabo por los integrantes del coro y (...) por las personas que se encargaron de custodiar los recursos musicales cedidos por el Patronato y de programar las diferentes actividades musicales en los municipios que gozaron de dichos recursos. A su vez, se recogen diversos testimonios que dan fe del cometido realizado por esta institución y del impacto cultural y musical que supuso en los habitantes de las localidades donde se desarrollaron las diferentes actividades misionales.

Body expression and dance are activities that contribute to the integral well-being of people. In an educational context, the process of evaluating our students implies variations in their moods. This study tackles the states of mind that students perceive before and after the evaluation of a practice in the subject ofBody expression and dance, developed through choreographies, that were, previously rehearsed, and later presented to the rest of the class in a specific session. Our main interest was the obtention of (...) information on the states of mind of the students prior to the evaluation of their choreographies, and again once they had been performed. The study design consisted of two phases: two different choreographies separated by an interval of 2 months. The students were asked about their moods before and after performing their choreographies, which were evaluated. The participants, 167 in total, 35 women and 132 men, aged 18 to 22 years old, filled out a POMS questionnaire, before and after the evaluation of each occasion. Differences were found in the stress-anxiety, vigor-activity, fatigue-immobility scales and the total mood score. In all of them, except for the fatigue-immobility scale, we found a decrease in scores after the performance, compared to scores before. For the Stress-Anxiety factor, lower values were observed in the post-tests in comparison to the pre-tests, and also lower values in the pre- and post-test scores regarding the second choreography. We conclude that the practical evaluation of the subject through choreography modifies the mood states of the students, favoring their well-being after its execution, which is why evaluation through practice is considered a positive element in the educational process.

Relationships between degree/area of academic formation and religious and Darwinian views are controversial. This study aimed to compare the religious beliefs and acceptance of Darwinian evolution between two contrasting South American scientific communities (Chile and Colombia), accounting for different degrees and areas of academic formation. In 2018, 115 last year bachelor students (surveyed as freshmen in 2014 for a previous study) from Chile, and 283 first/last year bachelor students, graduate students, and professors from Colombia, all belonging to biology, chemistry, or (...) physics, were surveyed. Chilean students/faculty were significantly more agnostic/atheist, more accepting of Darwinian evolution, and less creationist than their Colombian counterparts. Academic degree and area differently affected these views in both countries, as only in Chile there was a clear tendency among biologists and physicists with higher degrees to hold less religious and creationist views. Marked differences between the history, socioeconomic contexts, and especially in high school and university curricula of both countries might explain these results. (shrink)

Retrieval practice, relative to further study, leads to long-term memory enhancement known as the “testing effect.” The neurobiological correlates of the testing effect at retrieval, when the learning benefits of testing are expressed, have not been fully characterized. Participants learned Swahili-English word-pairs and were assigned randomly to either the Study-Group or the Test-Group. After a week delay, all participants completed a cued-recall test while undergoing functional magnetic resonance imaging. The Test-Group had superior memory for the word-pairs compared to the Study-Group. (...) While both groups exhibited largely overlapping activations for remembered word-pairs, following an interaction analysis the Test-Group exhibited differential performance-related effects in the left putamen and left inferior parietal cortex near the supramarginal gyrus. The same analysis showed the Study-Group exhibited greater activations in the dorsal MPFC/pre-SMA and bilateral frontal operculum for remembered vs. forgotten word-pairs, whereas the Test-Group showed the opposite pattern of activation in the same regions. Thus, retrieval practice during training establishes a unique striatal-supramarginal network at retrieval that promotes enhanced memory performance. In contrast, study alone yields poorer memory but greater activations in frontal regions. (shrink)

Innovation and sustainability are postulated as key variables for the future of large commercial distribution. In addition, the development of Information and Communication Technologies solutions, and especially those related to Artificial Intelligence and digitization, are particularly relevant factors in the current pandemic scenario in which retail companies operate. These tools are essential to face the derived changes in commercial relations, especially between companies and consumers. For all these reasons, this work aims to examine the effect of ICT, as a driving (...) factor for innovation and its direct and indirect impact on sustainability in retailing. Furthermore, this study takes into account the eventual differences in these relationships according to the types of store formats. To achieve the aforementioned objective, a theoretical model is proposed that is tested through an empirical study carried out on a sample of 510 consumers of three store formats of grocery retail formats in Spain. For the analysis of the data obtained, the partial least squares regression technique and the Multigroup Analysis were used. The results obtained confirm the direct and indirect effect of ICT on innovation and sustainability in grocery retailing. In addition, the results indicate that consumers unequally perceive the technological progress of companies. These differences are greater between discount stores versus hypermarkets and supermarkets. The larger the size of the store format, the higher the incidence of ICT in relation to innovation. Therefore, it is vital to take ICT into consideration, where Artificial Intelligence is imperative for the growth and development of sustainable competitive advantages in retail companies. (shrink)

By following the arguments between Coenraad J. Temminck and fellow ornithologists Louis J.-P. Vieillot and Nicholas Vigors, this paper sketches, to a degree, the state of zoological classification and nomenclature between 1825 and 1840 in Europe. The discussions revolved around the problems caused by an unstable nomenclature, the different definitions of genera and species and the best method to achieve a natural system of classification. As more and more naturalists concerned with classifying and arranging the groups of birds joined these (...) discussions, a broad platform for debate emerged around the 1840s that gave a major impulse to the disciplines of taxonomy and systematics. Natural history ceased to be dominated by a few influential scientific authorities and became the scientific field where debate preceded agreement and, with it, progress. With this ‘democratization’ of natural history, Temminck’s status significantly changed between 1815 and 1840. After that year, his own views on classification along with certain economical and political developments in The Netherlands led Temminck to abandon the arena of ornithology and therefore, to lose his scientific authority.

The advances of the Christian kingdoms in the war against Islam, their sharing of the same conditions of life and danger, the defence and protection of the borderline areas of the frontier, had as a result the existence of a great similarity in their institutional organization and social relations. In this way, a consideration of those common features is the best basis for the study of the fueros or cartas de población granted to the settlers of the new lands conquered (...) from the Moors.

En me posant le probleme de la méthode, je constate une diversité de solutions, et énetudiant cette diversité, je suis conduit à examiner, entre autres, la doctrine chrétienne.Mais pour comprendre cette doctrine, il faut que nous commencions par la priere, c’est-à-dire par la purification. Car c’est ainsi qu’en fait le christianisme commence toute action. Et alors, nous pouvons voir que la méthode cherchée est la croyance, mais sous des formes différentes : instinct, sensibilité, expérience, raison, pensée, esprit.Il у a donc (...) plusieurs méthodes, mais en toutes, il у a en une seule ; il у a une méthode, mais sous des formes différentes.

It is often suggested that social media is a hostile environment for critical thinking and that a major source for epistemic problems concerning social media is that it facilitates emotions. We argue that emotions per se are not the source of the epistemic problems concerning social media. We propose that instead of focusing on emotions, we should focus on the affective scaffolding of social media. We will show that some affective scaffolds enable desirable epistemic practices, while others obstruct beneficial epistemic (...) practices, or enable hostile epistemic practices. Particularly, we will show that emotions play a crucial role in the epistemic practice of critical thinking and that the affective scaffolding of social media can support, or hinder, online critical thinking. The upshot of our argument is that affective scaffoldings of social media can harness emotions to support beneficial epistemic practices, like online critical thinking. (shrink)

The practice of taking hand-written notes in lectures has been rediscovered recently because of several studies on its learning efficacy in the mainstream media. Students are enjoined to ditch their laptops and return to pen and paper. Such arguments presuppose that notes are taken in order to be revisited after the lecture. Learning is seen to happen only after the event. We argue instead that student’s note-taking is an educational practice worthy in itself as a way to relate to the (...) live event of the lecture. We adopt a phenomenological approach inspired by Vilém Flusser’s phenomenology of gestures, which assumes that a gesture like note-taking is always an event of thinking with media in which a certain freedom is expressed. But Flusser’s description of note-taking focusses on the individual note-taker. What about students’ note-taking in a lecture hall as a collective gesture? Nietzsche considered note-taking ‘mechanical,’ as if students were automatons who mindlessly transcribed a verbal flow, while Benjamin considered it an inaesthetic gesture: at best, boring; at worst, ‘painful to watch.’ In contrast, we argue that the educational potentiality of note-taking—or better, note-making—can be grasped only if we account for its mediaticity (as writing that displaces the voice), together with but distinct from its political potentiality as a collective mediality (as a ‘means without end’). Note-taking enables us to see how collective thinking emerges in the lecture, a kind of thinking that belongs neither to the lecturer nor the student, but emerges in the relation of attention established between the lecturer, students and their object of thought.

Online Public Shaming is a form of norm enforcement that involves collectively imposing reputational costs on a person for having a certain kind of moral character. OPS actions aim to disqualify her from public discussion and certain normal human relations. We argue that this constitutes an informal collective punishment that it is presumptively wrong to impose on others. OPS functions as a form of ostracism that fails to show equal basic respect to its targets. Additionally, in seeking to mobilise unconstrained (...) collective power with potentially serious punitive consequences, OPS is incompatible with due process values. (shrink)
