En 1670, el autor español Juan Caramuel publicó en Italia el segundo tomo de una magna obra, Mathesis biceps (publicada en latín), sobre el saber matemático de su época. En el mismo se incluía un capítulo (un "sintagma" según el propio Caramuel), titulado Kybeia ("juegos de dados" en griego), donde el autor introduce su idea del origen del juego y resuelve algunos problemas relacionados con los mismos, convirtiéndose en una de las obras tempranas sobre cálculo de probablidades. En este texto (...) se da un repaso a los antecedentes al trabajo de Caramuel relacionados con el cálculo de probabilidades, se analiza punto por punto la aportación de este autor al nuevo cálculo en su Kybeia, y se añade la traducción al castellano del mismo.

Using a comprehensive sample of U.S. non-profit hospitals from 2011 to 2015, we examine the effects of state community benefits regulation on the amount of charity care provided by and the operational efficiency of U.S. non-profit hospitals. First, we document that, under such regulations, non-profit hospitals provide more charity care and less compensated care as a proportion of net revenue. We infer from these findings that CBR has the potential to increase both non-profit hospitals’ amount of charity care and their (...) efficiency of operations. Second, by examining variation in CBR types, we find no differences between having provision or having reporting requirements on the amount of charity care offered. Moreover, when we consider CBR with both provision and reporting requirements, the combination of these two requirements does not incrementally enhance charity care offerings, suggesting that the requirements may serve as substitutes with comparable effect. Lastly, we show that several state-level characteristics influence the relationship between CBR and charity care: CBRs in states with a higher gross domestic product and percentage of revenue received in taxes have incrementally lower associations with charity care, while hospitals in states where populations have, on average, higher household incomes have greater associations between CBR and charity care. Our findings highlight the effects that state-enacted regulation can have on socially beneficial behavior by non-profits. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D (...) ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions. (shrink)

Aims: Attentional bias, alcohol craving, and anxiety have important implications in the development and maintenance of alcohol use disorder. The current study aims to test the effectiveness of a Virtual Reality Cue-Exposure Therapy to reduce levels of alcohol craving and anxiety and prompt changes in AB toward alcohol content.Method: A 49-year-old male participated in this study, diagnosed with severe AUD, who also used tobacco and illicit substances on an occasional basis and who made several failed attempts to cease substance misuse. (...) The protocol consisted of six VR-CET booster sessions and two assessment sessions over the course of 5 weeks. The VR-CET program consisted of booster therapy sessions based on virtual reality exposure to preferred alcohol-related cues and contexts. The initial and final assessment sessions were focused on exploring AB, alcohol craving, and anxiety using paper-and-pencil instruments and the eye-tracking and VR technologies at different time points.Results: Pre and post assessment sessions indicated falls on the scores of all instruments assessing alcohol craving, anxiety, and AB.Conclusions: This case report, part of a larger project, demonstrates the effectiveness of the VR-CET booster sessions in AUD. In the post-treatment measurements, a variety of instruments showed a change in the AB pattern and an improvement in craving and anxiety responses. As a result of the systematic desensitization, virtual exposure gradually reduced the responses to significant alcohol-related cues and contexts. The implications for AB, anxiety and craving are discussed. (shrink)

El Himno a san Demetrio (nº 71) de Romano Melodo presenta en su desenlace de la historia del martirio un excursus sin relación alguna con la leyenda del santo y las versiones de su hagiografía que traslada a los fieles oyentes un sentir eminentemente antiherético, en concreto, antimaniqueísta. En este artículo se propone una traducción a la lengua castellana de dicho fragmento griego y se analiza la digresión por parte del autor del texto hímnico, tratando de arrojar luz sobre el (...) contexto de producción y ejecución del kontákion en honor del santo tesalonicense.

Los fragmentos que aquí se presentan bajo el título de Notas de la razón son el producto de una investigación que apenas si ha alcanzado algunas certezas relativas, y que nace, como todas aquellas que aspiran a la condición de filosóficas, de algunas perplejidades, de algunos desconciertos y también, por qué no confesarlo, de la insólita sorpresa que a veces nos produce el hecho de que las cosas sean lo que son. El asombro que nos despierta lo que ya está (...) ahí, como si fuéramos oscuramente conscientes de que podría haber no estado o haberlo hecho de cualquier otra forma, se deriva de una evidencia imponderable: no sólo que la verdad existe, sino que nosotros no podríamos existir sin ella. Si la verdad está, podría afirmarse, parafraseando a Epicuro, estamos nosotros, pero si ella desaparece, nosotros no existimos o lo hacemos de forma improbable. En estas reflexiones se cuestionan verdades: sobre la propia verdad, sobre la belleza y el arte, sobre el bien, el yo y la tragedia… Hay también una fracasada aspiración de unidad que, tal vez, tan sólo se alcance en la perspectiva final del lector.

This essay defends that mimesis is an inherently agonistic and paradoxical human practice. The divergent views on mimesis by Plato and Aristotle, as well as by Adorno and Benjamin, are the philosophical manifestation of an agonistic tension of human mimesis that is not resolved in the exclusive truth of one of the positions, but remains as a permanent possibility to create alternative paths in history.
