Although it is commonly believed that the concept of brain death was developed to benefit organ transplants, it evolved independently. Transplantation owed its development to advances in surgery and immunosuppressive treatment; BD owed its origin to the development of intensive care. The first autotransplant was achieved in the early 1900s, when studies of increased intracranial pressure causing respiratory arrest with preserved heartbeat were reported. Between 1902 and 1950, the BD concept was supported by the discovery of EEG, Crile’s definition of (...) death, the use of EEG to demonstrate abolition of brain potentials after ischaemia, and Crafoord’s statement that death was due to cessation of blood flow. Transplantation saw the first xenotransplant in humans and the first unsuccessful kidney transplant from a cadaver. In the 1950s, circulatory arrest in coma was identified by angiography, and the death of the nervous system and coma dépassé were described. Murray performed the first successful kidney transplant. In the 1960s, the BD concept and organ transplants were instantly linked when the first kidney transplant using a brain-dead donor was performed; Schwab proposed to use EEG in BD; the Harvard Committee report and the Sydney Declaration appeared; the first successful kidney, lung and pancreas transplants using cadaveric donors were achieved; Barnard performed the first human heart transplant. This historical review demonstrates that the BD concept and organ transplantation arose separately and advanced in parallel, and only began to progress together in the late 1960s. Therefore, the BD concept did not evolve to benefit transplantation. (shrink)

Teniendo en cuenta que la filosofía es hija de la polis, a primera vista, el tema de la filosofía de la ciudad puede no revelar nada nuevo. De hecho, la filosofía y la ciudad cuentan una historia paralela. Es en el ágora, un espacio privilegiado para el ejercicio de la ciudadanía, donde la filosofía se desarrolla como debate de argumentos. Pero, aunque a lo largo de la historia las ciudades puedan reflejar un deseo civilizatorio, lo cierto es que la ciudad (...) contemporánea refleja muy poco de la realidad política de la polis, de la indiferenciación medieval entre lo público y lo privado o de la racionalidad normativa de la ciudad moderna. Las ciudades en el siglo xx, y especialmente en el siglo xxi, tienen que ver más con las relaciones sociales y económicas de la ciudad industrial y posindustrial. La progresiva mecanización del siglo xix y su extensión, en el siglo xx, a la automatización y a la digitalización, cambian definitivamente la forma en que nos relacionamos, pensamos y trabajamos —en resumen, cómo vivimos—. Con el establecimiento de un capitalismo de orden económico que afecta a todas las dimensiones de la vida de la ciudad, esta queda delimitada por el poder, revela las contradicciones de las sociedades urbanas diseñadas por los mercados y da lugar, según David Harvey, a la apropiación privada de la vida y los espacios.

¿Cómo pueden las emociones favorecer una sociedad democrática más justa y estable? El propósito de este artículo es destacar la importancia de las emociones en el pensamiento de M. C. Nussbaum, y cómo pueden contribuir, en el contexto del liberalismo político, a reforzar y dar estabilidad a la democracia. Todo ello parece exigir, según Nussbaum, integrar el papel de las emociones en el proyecto educativo de la sociedad, para superar el modelo de justicia centrado en el beneficio mutuo, ampliándolo con (...) otro, cuyo centro de gravedad serían las capacidades y el desarrollo humano. Y en tal sentido, es necesario preguntarse por el papel que han de jugar las humanidades, para dar viabilidad y continuidad a tal proyecto.How can emotions enable a fairer and more stable democratic society? The aim of this essay is to emphasize the importance of emotions in M.C. Nussbaum’s thought and how can they contribute to reinforce democracy and provide it with stability to in the context of political liberalism. All of this seems to require, according to Nussbaum, the integration of the role of emotions in society’s educational project, so as to go beyond the model of justice focused on the mutual benefit, widening it with another, whose centre of gravity would be the capacities and the human development. In this sense, it is necessary to ask ourselves about the role Humanities should play, so as to provide such a project with feasibility and continuity. (shrink)

Le XI.ème Congrès International de Philosophie Médiévale de la Société Internationale pour l’Étude de la Philosophie Médiévale (S.I.E.P.M..) s’est déroulé à Porto (Portugal), du 26 au 30 août 2002, sous le thème général: Intellect et Imagination dans la Philosophie Médiévale. A partir des héritages platonicien, aristotélicien, stoïcien, ou néo-platonicien (dans leurs variantes grecques, latines, arabes, juives), la conceptualisation et la problématisation de l’imagination et de l’intellect, ou même des facultés de l’âme en général, apparaissaient comme une ouverture possible pour aborder (...) les principaux points de la pensée médiévale. Les Actes du congrès montrent que « imagination » et « intellect » sont porteurs d’une richesse philosophique extraordinaire dans l’économie de la philosophie médiévale et de la constitution de ses spécificités historiques. Dans sa signification la plus large, la théorisation de ces deux facultés de l’âme permet de dédoubler le débat en au moins six grands domaines: — la relation avec le sensible, où la fantaisie/l’imagination joue le rôle de médiation dans la perception du monde et dans la constitution de la connaissance ; — la réflexion sur l’acte de connaître et la découverte de soi en tant que sujet de pensée ; — la position dans la nature, dans le cosmos, et dans le temps de celui qui pense et qui connaît par les sens externes, internes et par l’intellect ; — la recherche d’un fondement pour la connaissance et l’action, par la possibilité du dépassement de la distante proximité du transcendant, de l’absolu, de la vérité et du bien ; — la réalisation de la félicité en tant qu’objectif ultime, de même que la découverte d’une tendance au dépassement actif ou mystique de toutes les limites naturelles et des facultés de l’âme ; — la constitution de théories de l’image, sensible ou intellectuelle, et de ses fonctions. Les 3 volumes d’Actes incluent les 16 leçons plénières et 112 communications, ainsi que les index correspondants (manuscrits ; noms anciens et médiévaux ; noms modernes ; auteurs). Le volume IV des Actes, contenant 39 communications et des index, est publié par la revue " Mediaevalia. Textos e Estudos ", du Gabinete de Filosofia Medieval de l’Universidade do Porto (volume 23, de 2004). Ouvrage publié avec l’appui de l’Universidade do Porto, de la Faculdade de Letras da U.P., du Departamento de Filosofia - F.L.U.P. et de la Fundação para a Ciência e a Tecnologia (Portugal). (shrink)
Monetary intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the dark side of monetary Intelligence and behavioral economics—dishonesty. Dishonesty, a risky prospect, involves cost–benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: The magnitude and intensity of (...) the relationship between love of money and dishonest prospect may reveal how individuals frame dishonesty in the context of two levels of subjective norm—perceived corporate ethical values at the micro-level and Corruption Perceptions Index at the macro-level, collected from multiple sources. Based on 6382 managers in 31 geopolitical entities across six continents, our cross-level three-way interaction effect illustrates: As expected, managers in good barrels, mixed barrels, and bad barrels display low, medium, and high magnitude of dishonesty, respectively. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities —the Enron Effect, but the lowest in low CPI entities. CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norm, revealing critical implications to the field of behavioral economics and business ethics. (shrink)
The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Monetary Intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the bright side of Monetary Intelligence and behavioral economics, frames money attitude in the context of pay and life satisfaction, and controls money at the macro-level and micro-level. We theorize: Managers with low love of money motive but high stewardship behavior will have high subjective well-being: pay satisfaction and (...) quality of life. Data collected from 6586 managers in 32 cultures across six continents support our theory. Interestingly, GDP per capita is related to life satisfaction, but not to pay satisfaction. Individual income is related to both life and pay satisfaction. Neither GDP nor income is related to Happiness. Our theoretical model across three GDP groups offers new discoveries: In high GDP entities, “high income” not only reduces aspirations—“Rich, Motivator, and Power,” but also promotes stewardship behavior—“Budget, Give/Donate, and Contribute” and appreciation of “Achievement.” After controlling income, we demonstrate the bright side of Monetary Intelligence: Low love of money motive but high stewardship behavior define Monetary Intelligence. “Good apples enjoy good quality of life in good barrels.” This notion adds another explanation to managers’ low magnitude of dishonesty in entities with high Corruption Perceptions Index. In low GDP entities, high income is related to poor Budgeting skills and escalated Happiness. These managers experience equal satisfaction with pay and life. We add a new vocabulary to the conversation of monetary intelligence, income, GDP, happiness, subjective well-being, good and bad apples and barrels, corruption, and behavioral ethics. (shrink)
Since the mid-20th century, the study of Self-Regulated Learning has aimed to identify the distinctive characteristics that enable individuals to acquire new knowledge and skills under their control. The theory of Internal Self-Regulation vs. External-Regulation in Learning has postulated that a large number of self-regulatory variables are mediated by regulated/non-regulated or dysregulated features of the context. After signing their informed consent, a total of 616 university students completed validated instruments of SRL vs. ERL, behavioral regulation, regulatory teaching, and metacognitive study (...) control strategies. Using an ex-post facto design and correlation, regression, structural equation model and mediation analyses, the present research aimed to establish multicausal predictive relationships among the analyzed variables. Results indicated positive predictive effects between the external regulation variables on the self-regulation variables in learning [regulation /non-regulation /dysregulation ]; as well as positive predictive effects between SRL on SRB, RT and metacognitive SRS. Additionally, external regulation not only predicted but mediated numerous relations among the variables studied. Other findings and important considerations for future research in the field of self-regulation are discussed. (shrink)
Ouvrage majeur de la philosophie de Malebranche, De la recherche de la vérité constitue un moment clé dans la réflexion philosophique à l’âge classique. Si son inspiration est cartésienne, Malebranche y soutient d’emblée une théorie originale de la connaissance, de la vérité et de la causalité : notamment la thèse de la « vision en Dieu » des idées et l’analyse des causes de l’erreur. Plus qu’une théorie de la connaissance, c’est donc une théorie complète de l’esprit humain et de (...) ses multiples fonctions que nous livre l’ouvrage.Cette nouvelle édition de la Recherche de la vérité donne à lire pour la première fois dans un format accessible à tous, un texte majeur de la pensée moderne, héritier de l’âge classique et annonciateur des Lumières : les textes sont établis à partir des deux dernières éditions de 1700 et 1712 revues par Malebranche lui-même, et des trois premiers volumes des Œuvres Complètes publiées sous la direction d’André Robinet; l’orthographe a été modernisée. La ponctuation a fait l’objet d’une révision systématique; les textes cités en langue étrangère ont été traduits ou retraduits, et leurs références mises à jour afin de tenir compte des éditions les plus récentes.
