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.

© 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)

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.

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.

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.

Los desacuerdos acerca de la ontología científica han sido frecuentemente reconstruidos como el resultado de una disputa entre stances epistémicas rivales. En el presente trabajo, (i) caracterizamos algunos de estos desacuerdos como desacuerdos profundos. Además, (ii) mostramos que los desacuerdos profundos sobre ontología científica pueden surgir no solo de la adopción de diferentes stances epistémicas, sino entre posiciones que se encuadran dentro de una misma stance. El desarrollo de ese punto nos permite, a su vez, establecer una distinción entre tipos (...) de desacuerdos profundos y explorar la posibilidad de que existan diferencias de grado entre ellos.

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)

Geoffrey Rose’s prevention paradox points to a tension between two prima facie plausible moral principles: that we should save the greater number and that weshould save the most at risk. This paper argues that a novel moral theory, ex-ante contractualism, captures our intuitions in many prevention paradox cases, regardless of our interpretation of probability claims. However, it goes on to show that it might be impossible to square ex-ante contractualism with all of our moral intuitions. It concludes that even if (...) ex-ante contractualism cannot furnish an entire ethics of risk, it does identify important considerations for any such theory. (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.”.

Einstein, in his “Zur Elektrodynamik bewegter Körper”, gave a physical (operational) meaning to “time” of a remote event in describing “motion” by introducing the concept of “synchronous stationary clocks located at different places”. But with regard to “place” in describing motion, he assumed without analysis the concept of a system of co-ordinates.In the present paper, we propose a way of giving physical (operational) meaning to the concepts of “place” and “co-ordinate system”, and show how the observer can define both the (...) place and time of a remote event. Following Einstein, we consider another system “in uniform motion of translation relatively to the former”. Without assuming “the properties of homogeneity which we attribute to space and time”, we show that the definitions of space and time in the two systems are linearly related. We deduce some novel consequences of our approach regarding faster-than-light observers and particles, “one-way” and “two-way” velocities of light, symmetry, the “group property” of inertial reference frames, length contraction and time dilatation, and the “twin paradox”. Finally, we point out a flaw in Einstein’s argument in the “Electrodynamical Part” of his paper and show that the Lorentz force formula and Einstein’s formula for transformation of field quantities are mutually consistent. We show that for faster-than-light bodies, a simple modification of Planck’s formula for mass suffices. (Except for the reference to Planck’s formula, we restrict ourselves to Physics of 1905.).

The practice of prenatal screening for disability is sometimes objected to because of the hurt and offence such practices may cause to people currently living with disabilities. This objection is commonly termed “the expressivist objection”. In response to the objection it is standardly claimed that disabilities are analogous to illnesses. And just as it would be implausible to suppose reduction of the incidence of illnesses such as flu sends a negative message to ill people, so it is not plausible to (...) suppose prevention of disability sends a negative message to disabled people. The expressivist objection hinges, however, upon a view of the relationship between disability and self identity which sees disability as part of the identity of the disabled person, in a way in which illnesses such as flu cannot be. This possibility is generally not considered in critiques of the expressivist objection. In this paper, an “identity claim” to the effect that disabilities can be identity constituting is accepted and the force of the expressivist argument is reconsidered in the light of its acceptance. It is concluded that even when such an identity claim is accepted, the expressivist objection is still not morally compelling. (shrink)
