Disagreements about scientific ontology have frequently been reconstructed as the result of a dispute between rival epistemic stances. In this paper, (i) we characterize some of these disagreements as deep disagreements. In addition, we show that deep disagreements about scientific ontology can arise not only from the adoption of different epistemic stances, but also between positions that fall within the same stance. The development of this point allows us, in turn, to establish a distinction between types of deep disagreement and (...) to explore the possibility that there are differences of degree between them.

Dans les premiers chants de l’ Enfer, Dante déclare entre les lignes la tâche à laquelle il se sent appelé en tant que « poète chrétien » : d’un côté, il est invité à argumenter avec la rigueur du discours scientifique les vérités fondamentales de la religion ; de l’autre côté, il lui est confié la charge d’entraîner le lecteur dans une lecture anagogique de ces vérités en recourant aux fascinations allégoriques de la poésie. En accomplissant cette mission, Dante obtiendra, (...) pour lui-même et pour les autres êtres humains, cette perfection anthropologique naturelle qui culmine, après la mort terrestre, par le retour aux conditions métaphysiques qui se seraient actualisées en la personne d’Adam s’il n’avait pas péché. Cette conception est déjà opérante dans certaines pages de la Vie nouvelle et du Banquet, mais c’est surtout dans La Divine Comédie que Dante en revient spontanément à ce genre de techniques sur un mode original et particulièrement efficace. On en a un exemple éclairant quand, au Chant III de l’ Enfer, la poésie décrit le tourbillon, apparemment disharmonieux et dépourvu de sens, des sons qui émergent de la cavité infernale, en se basant non seulement sur l’application évidente d’au moins deux artifices rhétoriques déterminés, mais surtout sur l’évocation formellement rigoureuse des règles de la dialectique (selon la terminologie en usage dans les écoles) : le succès de cette opération dépend de la capacité, de la part du lecteur, de retrouver la signification authentique de la terminologie scientifique mise en œuvre en poésie, utilisée pour illustrer les vérités de la foi et la nouvelle beauté de la synthèse entre art poétique et disciplines du Trivium.

C’est à travers la lecture de l’Isagoge de Porphyre commentée par Boèce que l’idée d’une organisation hiérarchique du réel, fondée sur la division des genres, des espèces et des différences, était introduite dans le patrimoine culturel des intellectuels du haut Moyen Âge au niveau élémentaire de l’étude de la dialectique. Cette étude, fondement du curriculum pédagogique des arts libéraux, impliquait une considération réaliste des formes de la pensée logiquement ordonnées : seules structures authentiques du point de vue ontologique, les formes (...) sont aussi les seuls objets de la connaissance scientifique puisqu’elles seules sont véritablement exemptes de la vicissitude et de l’accidentalité. Tout au long du haut Moyen Âge, le débat, polymorphe et complexe, sur la nature des universaux introduit donc la comparaison dynamique entre différentes conceptions du réel, de la connaissance et de la science, et aussi de la capacité du langage humain de dire, de manifester et de communiquer la vérité. L’analyse historique de l’évolution et des conséquences de cette perspective philosophique, d’origine porphyrienne d’une part, boécienne et augustinienne de l’autre, se développe ici à travers certains épisodes de la spéculation du haut Moyen Âge, et en particulier à l’époque carolingienne, cherchant à contribuer à une meilleure intelligence de la naissance de la méthodologie des sciences particulières et, plus spécifiquement, de la théologie.

No presente trabalho é examinado o conceito de "representação" em duas obras de Nicolau de Oresme. No De maneta, o pensador medieval faz pequenas referências ao poder de decisão do povo em questões monetárias. Anos mais tarde, ao traduzir e comentar a Política de Aristóteles, retoma a noção de Marsílio de Pádua a respeito da multidão como legislador, mas define a multidão não como o povo, mas como a congregação de todos os príncipes ou oficiais, entre os principais cidadãos.

El Tractus de regia potesate et papali de Juan Ouidort de paris O. P. tienecomo objetivo principal, como dice en el premeio,considerar "circa potestatem ecclesiaticorumpontificurn" con el fin de refutar todo argumentoque pretenda otorgar al papado "dominum inrebus". or nuestra parte trataremos de rastrear enlos argumnentos que Juan esgrime de contrapesopara con la teocracia papal los elementos que nospermitan reconstruir su concepción de la naturalezae historia del hombre. A1 respectose haa seíialadola deuda que posee el Tractatus respecto de lacorriente naturalista (...) que arranca con los textosaristotélicos redescubiertos y especialmente por loscomentarias tomísticos a los "libri moralesAristotelis". Sin embargo, a partir de una lecturaminuciosa de! misto no se sigue que Juan sea unautor aristotélico. La recurrencia a determinadasafirmaciones de Aristóteles responden, en rigor,más a la moda que a una fundamentación sobre lanaturaleza del hombre y la sociedad. Antes bien,para ésta Juan recurre a la tradición estoicociceronianay especialmente a los textos de Cicerónde más amplio rendimiento ético-politico en elmedioevo, el De inventione y elDe ofti.ciis. Así, la versión latina, "homo animalpoliticurn et sociale", de la definición aristotélica estematizada por Juan no aristotélica, sinociceronianamente. Hay tres etapas, una bestial, outra social y la tercera civil que se suceden progresivamente. Cadauna de las cuales supera la anterior; huarda cadauna determinadas caraterísticas y, con todo,poseen un denominador común, detonante tanto deconflictos como de derecho: la propiedad privada.

Physicians who care for critically ill people with opioid use disorder frequently face medical, legal, and ethical questions related to the provision of life-saving medical care. We examine a complex medical case that illustrates these challenges in a person with relapsing injection drug use. We focus on a specific question: Is futility an appropriate and useful standard by which to determine provision of life-saving care to such individuals? If so, how should such determinations be made? If not, what alternative decisionmaking (...) framework exists? We determine that although futility has been historically utilized as a justification for withholding care in certain settings, it is not a useful standard to apply in cases involving people who use injection drugs for non-medical purposes. Instead, we are welladvised to explore each patient's situation in a holistic approach that includes the patient, family members, and care providers in the decision-making process. The scope of the problem illustrated demonstrates the urgent need to definitively improve outcomes in people who use injection drugs. Increasing access to high quality medication-assisted treatment and psychiatric care for individuals with opioid use disorder will help our patients achieve a sustained remission and allow us to reach this goal.

Firearm injury in the United States is a public health crisis in which physicians are uniquely situated to intervene. However, their ability to mitigate harm is limited by a complex array of laws and regulations that shape their role in firearm injury prevention. This piece uses four clinical scenarios to illustrate how these laws and regulations impact physician practice, including patient counseling, injury reporting, and the use of court orders and involuntary holds. Unintended consequences on clinical practice of laws intended (...) to reduce firearm injury are also discussed. Lessons drawn from these cases suggest that physicians require more nuanced education on this topic, and that policymakers should consult front-line healthcare providers when designing firearm policies.

BackgroundInformation and communication technology solutions have the potential to support active and healthy aging and improve monitoring and treatment outcomes. To make such solutions acceptable, all stakeholders must be involved in the requirements elicitation process. Due to the COVID-19 situation, alternative approaches to commonly used face-to-face methods must often be used. One aim of the current article is to share a unique experience from the Pharaon project where due to the COVID-19 outbreak alternative elicitation methods were used. In addition, an (...) overview of common functional, quality, and emotional goals identified by six pilot sites is presented to complement the knowledge about the needs of older adults.MethodsOriginally planned face-to-face co-creation seminars were impossible to carry out, and all pilot sites chose alternative requirements elicitation methods that were most suitable in their situation. The elicited requirements were presented in the form of goal models. In one summary goal model, we provide an overview of common functional, quality, and emotional goals.ResultsDifferent elicitation methods were combined based on the digital literacy of the target group and their access to digital tools. Methods applied without digital technologies were phone interviews, reviews of literature and previous projects, while by means of digital technologies online interviews, online questionnaires, and virtual co-creation seminars were conducted. The combination of the methods allowed to involve all planned stakeholders. Virtual and semi-virtual co-creation seminars created collaborative environment comparable to face-to-face situations, while online participation helped to save the time of the participants. The most prevalent functional goals elicited were “Monitor health,” “Receive advice,” “Receive information.” “Easy to use/comfortable,” “personalized/tailored,” “automatic/smart” were identified as most prevalent quality goals. Most frequently occurring emotional goals were “involved,” “empowered,” and “informed.”ConclusionThere are alternative methods to face-to-face co-creation seminars, which effectively involve older adults and other stakeholders in the requirements elicitation process. Despite the used elicitation method, the requirements can be easily transformed into goal models to present the results in a uniform way. The common requirements across different pilots provided a strong foundation for representing detailed requirements and input for further software development processes. (shrink)

This qualitative study describes the lived experience of physicians who work in communities that have experienced a public mass shooting. Semi-structured interviews were conducted with seventeen physicians involved in eight separate mass casualty shooting incidents in the United States. Four major themes emerged from constant comparative analysis: The psychological toll on physicians: “I wonder if I'm broken”; the importance of and need for mass casualty shooting preparedness: “[We need to] recognize this as a public health concern and train physicians to (...) manage it”; massive media attention: “The media onslaught was unbelievable”; and commitment to advocacy for a public health approach to firearm violence: “I want to do whatever I can to prevent some of these terrible events.”.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

The ageing society poses significant challenges to Europe’s economy and society. In coming to grips with these issues, we must be aware of their ethical dimensions. Values are the heart of the European Union, as Article 1a of the Lisbon Treaty makes clear: “The Union is founded on the values of respect for human dignity…”. The notion of Europe as a community of values has various important implications, including the development of inclusion policies. A special case of exclusion concerns the (...) gap between those people with effective access to digital and information technology and those without access to it, the “digital divide”, which in Europe is chiefly age-related. Policies to overcome the digital divide and, more generally speaking, e-inclusion policies addressing the ageing population raise some ethical problems. Among younger senior citizens, say those between 65 and 80 years old, the main issues are likely to be universal access to ICT and e-participation. Among the older senior citizens, say those more than 80 years old, the main issues are mental and physical deterioration and assistive technology. An approach geared towards the protection of human rights could match the different needs of senior citizens and provide concrete guidance to evaluate information technologies for them. (shrink)

Prawitz has recently developed a theory of epistemic grounding that differs in many respects from his earlier semantics of arguments and proofs. An innovative approach to inferences yields a new conception of the intertwinement of the notions of valid inference and proof. We aim at singling out three reasons that may have led Prawitz to the ground-theoretic turn, i.e.: a better order in the explanation of the relation between valid inferences and proofs; a notion of valid inference based on which (...) valid inferences and proofs are recognisable as such; a reconstruction of the deductive activity that makes inferences capable of yielding justification per se. These topics are discussed by Prawitz with reference to a very general and ancient question: why and how correct deduction has the epistemic power to compel us to accept its conclusions, provided its premises are justified? We conclude by remarking that, in spite of some improvements, the ground-theoretic approach shares with the previous one a problem of vacuous validity which, as Prawitz himself points out, blocks in both cases a satisfactory explanation of epistemic compulsion. (shrink)

We define a class of formal systems inspired by Prawitz’s theory of grounds. The latter is a semantics that aims at accounting for epistemic grounding, namely, at explaining why and how deductively valid inferences have the power to epistemically compel to accept the conclusion. Validity is defined in terms of typed objects, called grounds, that reify evidence for given judgments. An inference is valid when a function exists from grounds for the premises to grounds for the conclusion. Grounds are described (...) by formal terms, either directly when the terms are in canonical form, or indirectly when they are in non-canonical form. Non-canonical terms must reduce to canonical form, and two terms may be said to be equal when they converge towards equivalent grounds. In our systems these properties can be proved through rules distinguished according to whether they concern types or logic. Type rules involve type introduction and elimination, equality for application of operational symbols, and re-writing equations for non-canonical terms. The logic amounts to a sort of intuitionistic system in a Gentzen format. To conclude, we show that each system of our class enjoys a normalization property. (shrink)

Dag Prawitz’s theory of grounds proposes a fresh approach to valid inferences. Its main aim is to clarify nature and reasons of their epistemic power. The notion of ground is taken to denote what one is in possession of when in a state of evidence, and valid inferences are described in terms of operations that make us pass from grounds we already have to new grounds. Thanks to a rigorously developed proof-as-chains conception, the ground-theoretic framework permits Prawitz to overcome some (...) conceptual difficulties of his earlier proof-theoretic explanation. Though from different points of view, anyway, the two accounts share an issue of recognizability of relevant operational properties. (shrink)
