Las tareas de descripción documental en los Archivos de la Catedral y del Arzobispado de Sevilla han permitido identificar un documento pontificio original de Gregorio IX, datado en el año 1227, dirigido a las curias eclesiásticas a las que manda proteger y favorecer a la Orden de Predicadores en su expansión y misión evangelizadora, veintiún años antes de la restauración del culto cristiano en Sevilla por Fernando III en 1248, convirtiéndose en el documento original más antiguo conservado hasta la fecha (...) en estos Archivos. En este artículo profundizamos en el análisis del contexto de producción del documento, lo ponemos en relación con otros de contenido idéntico, y trazamos su historia archivística, Todo ello nos permite valorar su interés y destacado papel como testimonio de un proceso histórico de la Iglesia bajomedieval, más allá de su singular antigüedad o de su breve contenido.

In his famous letter to A. N. Prior dated 3 September 1958, Saul Kripke suggested the use of branching time in temporal logic. In this paper, however, it is argued that Prior worked with an idea close to the notion of branching time (‘the big Y’) already the year before he received Kripke’s letter. It is likely that Prior’s findings based on this early study can explain why Prior so quickly accepted the idea of branching time when he received Kripke’s (...) letter. (shrink)

Objective To develop an ethically, legally, and clinically appropriate ventilator allocation policy for AdventHealth Tampa and AdventHealth Carrollwood in Tampa, Florida, which could be enacted swiftly during the Covid-19 pandemic. Methods During Spring 2020, a subcommittee of the Medical Ethics Committee established consensus on the fundamental principles of the policy, then built on existing ethical, legal, and clinical guidance. Results The plan was finalized in May 2020. The plan triages patients based on exclusion criteria (imminent mortality), prognosis and expected benefit (...) of ventilation (using the Sequential Organ Failure Assessment), and change in prognosis over time. Decisions are made by committee in order to minimize moral distress among individual patient care providers. Conclusions Due to international concerns about healthcare resource shortages during the Covid-19 pandemic, hospitals need allocation policies informed by the crisis standard of care, the hospital’s ethical duty to plan for an emergency, and federal civil rights laws Policy Implications: This type of policy can serve as a model for other institutions to develop crisis standards of care resource allocation policies, which are a necessary component of disaster planning.

El legado científico filosófico de Max Born, al estar vinculado a la conocida como interpretación ortodoxa de la mecánica cuántica o interpretación de Copenhague, ha sido entendido desde el marco de una filosofía de la ciencia de corte instrumentalista, considerando su interpretación probabilística de la función de onda como la más clara defensa de una postura indeterminista acausal. Frente a este orden de cosas, este artículo pretende lograr dos objetivos. El primero consiste en mostrar cómo la interpretación de Born, a (...) pesar de instaurar de forma definitiva el indeterminismo en el ámbito de la física elemental, no implica el abandono de una explicación causal de los fenómenos físicos. El segundo trata de defender la posibilidad de reivindicar una interpretación "realista" de la labor científica a partir de la noción de "invariantes observaciones" que Born propone, conciliando el aspecto dual de la realidad elemental en favor de su carácter corpuscular y analizando la aporética noción de "probabilidad objetiva" que su interpretación instaura. Max Born's philosophic and scientific legacy is related to the orthodox interpretation of quantum mechanics, which is known as the Interpretation of Copenhague. Therefore Born's statistical interpretation has been considered as defending a positivist philosophy of science. Opposing this idea, this article is intended to face two main questions. The first one deals with the fact that Born's interpretation of wave function, although it settles indeterminism, does not imply the abandonment of causal explanations of physical phenomena The second one is aimed at showing how is it possible to defend a "realistic view" of scientific labour making use of the notion of "invariant observationals" that leads to the reconciliation of wave and corpuscular theories.

Una de las principales causas de que el visón europeo, Mustela lutreola, esté en peligro de extinción es la industria peletera. Por un lado, durante los siglos XIX y XX, la caza por su piel causó un grave declive en la especie. Por otro lado, a partir de la década de 1920, la peletería fue substituyendo la caza por la cría en cautividad, y Europa se llenó de granjas de visón americano, Neovison vison; los ejemplares fugados de ellas están colonizando (...) el continente y se han convertido en una amenaza para el visón europeo. Actualmente, algunos países comienzan a prohibir estas granjas, que en cambio aumentan en España. El objetivo de este artículo es analizar este caso concreto como un ejemplo de que nuestros gustos estéticos pueden resultar dañinos e incluso letales para otras especies y la naturaleza en general.

Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

We analyze the dynamics of repeated interaction of two players in the Prisoner's Dilemma under various levels of interdependency information and propose an instance-based learning cognitive model to explain how cooperation emerges over time. Six hypotheses are tested regarding how a player accounts for an opponent's outcomes: the selfish hypothesis suggests ignoring information about the opponent and utilizing only the player's own outcomes; the extreme fairness hypothesis weighs the player's own and the opponent's outcomes equally; the moderate fairness hypothesis weighs (...) the opponent's outcomes less than the player's own outcomes to various extents; the linear increasing hypothesis increasingly weighs the opponent's outcomes at a constant rate with repeated interactions; the hyperbolic discounting hypothesis increasingly and nonlinearly weighs the opponent's outcomes over time; and the dynamic expectations hypothesis dynamically adjusts the weight a player gives to the opponent's outcomes, according to the gap between the expected and the actual outcomes in each interaction. When players lack explicit feedback about their opponent's choices and outcomes, results are consistent with the selfish hypothesis; however, when this information is made explicit, the best predictions result from the dynamic expectations hypothesis.

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

There is no doubt that the use of Internet for purchasing products and services has constituted a crucial change in how people go about buying them. In the era of digital transformation, the possibility of accessing information provided by other users about their personal experiences has taken on more weight in the selection and buying processes. On these lines, traditional word-of-mouth has given way to electronic word-of-mouth, which constitutes a major social change. This behavior is particularly relevant in the services (...) area, where potential users cannot in advance assess what is on offer. There is an abundant literature analyzing the effects of eWOM on different variables of interest in this sector. However, little is known about the factors that determine eWOM. Thus, the main objective of the present paper is to analyze the impact of two variables on eWOM. Both of them are crucial for potential customers in the process of finding hotel accommodations and they can motivate people to make such comments. The results demonstrate that these variables truly have a significant impact on whether or not users make comments on line. Moreover, it proved possible to observe certain differences according to the profile of the tourist involved and the destination where the hotel is located. In the current changing environment, this information is of great use for hotel managers in order to design strategies according to the type of guest they wish to attract. (shrink)

Hablar de ciencia moral es equívoco, pues depende del concepto de ciencia que manejemos, clásico, moderno o contemporáneo. Por otra parte, aun si aceptamos la posibilidad de una ciencia moral, queda pendiente la cuestión de su estatuto epistemológico: si es una ciencia práctica, si es una ciencia especulativa, y, en todo caso, qué relación guarda con la metafísica. En este artículo se examinan estos tres temas en el pensamiento de Santo Tomás de Aquino, teniendo presentes las objeciones que se han (...) planteado dentro y fuera del tomismo. (shrink)

This work focuses on the application of machine learning techniques to assist the clinicians in the administration of analgesic drug during general anaesthesia. Specifically, the main objective is to propose the basis of an intelligent system capable of making decisions to guide the opioid dose changes based on a new nociception monitor, the analgesia nociception index. Clinical data were obtained from 15 patients undergoing cholecystectomy surgery. By means of an off-line study, machine learning techniques were applied to analyse the possible (...) relationship between the analgesic dose changes performed by the physician due to the hemodynamic activity of the patients and the evolution of the ANI. After training different classifiers and testing the results under cross validation, a preliminary relationship between the evolution of ANI and the dosage of remifentanil was found. These results evidence the potential of the ANI as a promising index to guide the infusion of analgesia. (shrink)

Disregard of gender and of women’s contributions in the higher education curriculum is still a widespread phenomenon. Building on feminist institutionalism, this article explores the forms and types of resistance that efforts to engender the higher education curriculum must contend with and discusses the ways in which resistance to curricular reform is entrenched in a web of both gender-specific and apparently gender-neutral academic informal rules. In doing so, the authors use empirical evidence collected by an action-research project undertaken at a (...) faculty of political and social sciences in a Catalan public university. The Spanish case is intriguing because mainstreaming gender in higher education has been prescribed by various national and regional laws that are nonetheless poorly implemented. The article also reflects on the positive feedback loop action-research projects can facilitate within gendered institutions such as universities and pinpoints the role of feminist agency in counteracting resistance to institutional change.

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

The poetic work of Paul Celan provides an opportunity to display how Hans-Georg Gadamer’s hermeneuticsdialogues with texts. The article reconstructs Gadamer’s reading of some of the poems of Celan and contrasts this interpretative approach to that of Jacques Derrida, representative of a trend of hermeneutics known as deconstruction and which is inspired by the philosophy of Martin Heidegger. Derrida, who is also reader and admirer of Celan, stresses the open, secret, and unspeakable nature of the poem in contrast to the (...) hermeneuticprinciple of Gadamer that emphasizes the recovery of meaning. Despite the differences of both approaches, thearticle argues that they address some form of negativity within the poem, whose silence questions and motivatesboth readings, though they go in different directions. Being able to listen carefully to the negativity of thepoem, to what is unspeakable within the poetic work of Celan, reveals itself as a common motivation in these contemporaneous philosophers, which turns out to make them look closer than they appear to be at first sight.
