The role played by the symmetric structure of a group of finite Morley rank without involutions in the proof by contradiction of Frécon 2018 was put in evidence in Poizat 2018; indeed, this proof consists in the construction of a symmetric space of dimension two (“a plane”), and then in showing that such a plane cannot exist.To a definable symmetric subset of such a group are associated symmetries and transvections, that we undertake here to study in the abstract, without (...) mentioning a group envelopping them. This leads us to consider axiomatically defined structures that we callsymmetrons(preferably todyadic symmetric setsas was done in Lawson & Lim 2004).Glauberman's$Z^*$-Theorem allows to elucidate completely the structure of the finite symmetrons: each of them is isomorphic to the set of symmetries associated to a symmetric subspace of a finite group without involutions, which is far from being uniquely determined. In fact, there exist non-isomorphic finite groups which have the same symmetries, and also finite symmetrons which are not isomorphic to the symmetries of a group.The situation is not so clear in the case of symmetrons of finite Morley rank, or even algebraic, which are the main objects of study of this paper. But in spite of the fact that a symmetron be a structure much weaker that a group, we can extend to symmetrons some well-known results concerning groups of finite Morley rank: chain condition, decomposition into connected components, characterisation of the generic definable subsets, elliptic generation, etc. These properties are new even in the case of a symmetric subspace of a group, and allow to bypass the computations made by Frécon during the construction of his paradoxical plane.Moreover, assuming the Algebricity Conjecture, we generalize Glauberman's Theorem to the finite Morley rank context.

We comment on an early and inspiring remark of an Omskian mathematician concerning the Cherlin—Zilber Conjecture, meeting in passing some well-known properties of algebraic groups whose generalization to arbitrary groups of finite Morley rank seems to be very uncertain. This paper assumes a familiarity with the model theoretic tools involved in the study of the groups of finite Morley rank.

Since 1986 Darwin College, Cambridge has organised a series of annual public lectures built around a single theme approached in a multi-disciplinary way. These essays were developed from the 2008 lectures, which explored the idea of serendipity – the relationship between good fortune and the preparation of the mind to spot and exploit it. Serendipity is an appealing concept, and one which has been surprisingly influential in a great number of areas of human discovery. The essays collected in this volume (...) provide insightful and entertaining accounts of the relationship between serendipity and knowledge, in the human and natural sciences. Written by some of the most eminent thinkers of this generation, Serendipity explores a variety of subjects, including disease, politics, scientific invention and the art of writing. This collection will fascinate and inspire a wide range of readers, highlighting the multifaceted nature of the popular, but elusive, concept of serendipity. -/- Contents: Introduction.

As the range of potential uses for Artificial Intelligence, in particular machine learning, has increased, so has awareness of the associated ethical issues. This increased awareness has led to the realisation that existing legislation and regulation provides insufficient protection to individuals, groups, society, and the environment from AI harms. In response to this realisation, there has been a proliferation of principle-based ethics codes, guidelines and frameworks. However, it has become increasingly clear that a significant gap exists between the theory of (...) AI ethics principles and the practical design of AI systems. In previous work, we analysed whether it is possible to close this gap between the ‘what’ and the ‘how’ of AI ethics through the use of tools and methods designed to help AI developers, engineers, and designers translate principles into practice. We concluded that this method of closure is currently ineffective as almost all existing translational tools and methods are either too flexible or too strict. This raised the question: if, even with technical guidance, AI ethics is challenging to embed in the process of algorithmic design, is the entire pro-ethical design endeavour rendered futile? And, if no, then how can AI ethics be made useful for AI practitioners? This is the question we seek to address here by exploring why principles and technical translational tools are still needed even if they are limited, and how these limitations can be potentially overcome by providing theoretical grounding of a concept that has been termed ‘Ethics as a Service.’.

Background The phenomenon of ‘moral distress’ has continued to be a popular topic for nursing research. However, much of the scholarship has lacked conceptual clarity, and there is debate about what it means to experience moral distress. Moral distress remains an obscure concept to many clinical nurses, especially those outside of North America, and there is a lack of empirical research regarding its impact on nurses in the United Kingdom and its relevance to clinical practice. Research aim To explore the (...) concept of moral distress in nursing both empirically and conceptually. Methodology Feminist interpretive phenomenology was used to explore and analyse the experiences of critical care nurses at two acute care trauma hospitals in the United Kingdom. Empirical data were analysed using Van Manen’s six steps for data analysis. Ethical considerations The study was approved locally by the university ethics review committee and nationally by the Health Research Authority in the United Kingdom. Findings The empirical findings suggest that psychological distress can occur in response to a variety of moral events. The moral events identified as causing psychological distress in the participants’ narratives were moral tension, moral uncertainty, moral constraint, moral conflict and moral dilemmas. Discussion We suggest a new definition of moral distress which captures this broader range of moral events as legitimate causes of distress. We also suggest that moral distress can be sub-categroised according to the source of distress, for example, ‘moral-uncertainty distress’. We argue that this could aid in the development of interventions which attempt to address and mitigate moral distress. Conclusion The empirical findings support the notion that narrow conceptions of moral distress fail to capture the real-life experiences of this group of critical care nurses. If these experiences resonate with other nurses and healthcare professionals, then it is likely that the definition needs to be broadened to recognise these experiences as ‘moral distress’. (shrink)

Healthcare systems across the globe are struggling with increasing costs and worsening outcomes. This presents those responsible for overseeing healthcare with a challenge. Increasingly, policymakers, politicians, clinical entrepreneurs and computer and data scientists argue that a key part of the solution will be ‘Artificial Intelligence’ (AI) – particularly Machine Learning (ML). This argument stems not from the belief that all healthcare needs will soon be taken care of by “robot doctors.” Instead, it is an argument that rests on the classic (...) counterfactual definition of AI as an umbrella term for a range of techniques that can be used to make machines complete tasks in a way that would be considered intelligent were they to be completed by a human. Automation of this nature could offer great opportunities for the improvement of healthcare services and ultimately patients’ health by significantly improving human clinical capabilities in diagnosis, drug discovery, epidemiology, personalised medicine, and operational efficiency. However, if these AI solutions are to be embedded in clinical practice, then at least three issues need to be considered: the technical possibilities and limitations; the ethical, regulatory and legal framework; and the governance framework. In this article, we report on the results of a systematic analysis designed to provide a clear overview of the second of these elements: the ethical, regulatory and legal framework. We find that ethical issues arise at six levels of abstraction (individual, interpersonal, group, institutional, sectoral, and societal) and can be categorised as epistemic, normative, or overarching. We conclude by stressing how important it is that the ethical challenges raised by implementing AI in healthcare settings are tackled proactively rather than reactively and map the key considerations for policymakers to each of the ethical concerns highlighted.

RésuméPour tout entier n, on construit des sous-groupes, infiniment définissables de rang de Lascar ωn, du groupe additif d’un corps séparablement clos.

Non-perfect separably closed fields are stable, and not superstable. As a result, not all types can be ranked. We develop here a new tool, a "semi-rank", which takes values in the non-negative reals, and gives a sufficient condition for forking of types. This semi-rank is built up from a transcendence function, analogous to the one considered by Kolchin in the context of differentially closed fields. It yields some orthogonality and stratification results. /// Un corps séparablement clos non algébriquement clos est (...) stable sans être superstable. Cela signifie que seuls certains de ses types sont rangés. Nous développons un autre outil, un "semi-rang" à valeurs réelles, qui donne un critère de déviation des types. Ce semi-rang est construit à partir d'un analogue de la fonction de Kolchin associée à un type au-dessus d'un corps différentiel. Il produit des résultats de stratification des modèles et des résultats d'orthogonalité. (shrink)

Our intuitive assumption that only organisms are the real individuals in the natural world is at odds with developments in cell biology, ecology, genetics, evolutionary biology, and other fields. Although organisms have served for centuries as nature’s paradigmatic individuals, science suggests that organisms are only one of the many ways in which the natural world could be organized. When living beings work together—as in ant colonies, beehives, and bacteria-metazoan symbiosis—new collective individuals can emerge. In this book, leading scholars consider the (...) biological and philosophical implications of the emergence of these new collective individuals from associations of living beings. The topics they consider range from metaphysical issues to biological research on natural selection, sociobiology, and symbiosis. -/- The contributors investigate individuality and its relationship to evolution and the specific concept of organism; the tension between group evolution and individual adaptation; and the structure of collective individuals and the extent to which they can be defined by the same concept of individuality. These new perspectives on evolved individuality should trigger important revisions to both philosophical and biological conceptions of the individual. -/- Contributors: Frédéric Bouchard, Ellen Clarke, Jennifer Fewell, Andrew Gardner, Peter Godfrey-Smith, Charles J.

Since the later decades of the 20 th century, Brazilian psychologists have been questioning a theoretical and interventional model in educational contexts, which consider psychological phenomena apart from their cultural contexts, in order to develop an approach based on a contextualized viewpoint. Despite progress having been made in educational psychology, as a result of this critical paradigm, this area still has problems to overcome: Psychologists are becoming increasingly separate from schools, and it is now common to find psychologists who are (...) professionally unprepared to perform in this context and furthermore, school principals do not always understand the role of psychologists in educational settings. However, educational demands exist in psychologists’ daily work in a range of contexts, indicating the relevance of this field and the urgency to improve psychologists' qualifications. Considering that Brazilian professional development programs for educators and psychologists are usually restricted to technical learning, often ignoring professionals’ real needs and claims, this research aimed to develop a special type of professional development program looking at the group as a source of development, in order to rethink professional development process from within a collaborative perspective. Research data was generated from a professional development program offered for psychologists and professionals who work within educational settings. This programme involved collaborative group work and was organized and conducted in such a way as to create conditions for change. Concepts of cultural-historical theory – social situation of development, crisis and perezhivanie – were used as analytic tools for data analysis. Analysis indicated the importance of the group as a source of development through dialogue and the co-construction of new ideas and possibilities. (shrink)

Borovik proposed an axiomatic treatment of Morley rank in groups, later modified by Poizat, who showed that in the context of groups the resulting notion of rank provides a characterization of groups of finite Morley rank [2]. (This result makes use of ideas of Lascar, which it encapsulates in a neat way.) These axioms form the basis of the algebraic treatment of groups of finite Morley rank undertaken in [1].There are, however, ranked structures, i.e., structures on which (...) a Borovik-Poizat rank function is defined, which are not ℵ0-stable [1, p. 376]. In [2, p. 9] Poizat raised the issue of the relationship between this notion of rank and stability theory in the following terms: “… ungroupede Borovik est une structure stable, alors qu'un univers rangé n'a aucune raison de l'être …” (emphasis added). Nonetheless, we will prove the following:Theorem 1.1.A ranked structure is superstable.An example of a non-ℵ0-stable structure with Borovik-Poizat rank 2 is given in [1, p. 376]. Furthermore, it appears that this example can be modified in a straightforward way to give ℵ0-stable structures of Borovik-Poizat rank 2 in which the Morley rank is any countable ordinal (which would refute a claim of [1, p. 373, proof of C.4]). We have not checked the details. This does not leave much room for strenghthenings of our theorem. On the other hand, the proof of Theorem 1.1 does give a finite bound for the heights of certain trees of definable sets related to unsuperstability, as we will see in Section 5. (shrink)

We prove that a nonabelian superstable CSA-group has an infinite definable simple subgroup all of whose proper definable subgroups are abelian. This imply in particular that the existence of nonabelian CSA-group of finite Morley rank is equivalent to the existence of a simple bad group all whose definable proper subgroups are abelian. We give a new proof of a result of Mustafin and Poizat [E. Mustafin, B. Poizat, Sous-groupes superstables de SL2 ] which states that a superstable model (...) of the universal theory of nonabelian free groups is abelian. We deduce also that a superstable torsion-free hyperbolic group is cyclic. We close the paper by showing that an existentially closed CSA*-group is not superstable. (shrink)

It is known that in differentially closed fields of characteristic zero, the ranks of stability $RU$, $RM$ and the topological rank $RH$ need not to be equal. Pillay and Pong have just shown however that the ranks $RU$ and $RM$ coincide in a group definable in this theory. At the opposite, we will show in this paper that the ranks $RM$ and $RH$ of a definable group can also be different, and even lead to non-equivalent notions of generic type.

Résumé Et toi, quel est ton genre? Les Betty, intellectuelles précaires, partageant un désir militant, critiques tant vis-à-vis des groupes féministes historiques, que des pratiques politiques au sein du mouvement des mouvements, nous racontent leur création d’un espace, le "sexishock" au cœur même d’un centre social à Bologne.

L’œuvre de Copernic est à la fois tournée vers l’avenir par le système héliocentrique du monde qu’elle inaugure, et vers le passé par sa fidélité au principe du mouvement réel circulaire et uniforme des astres, hérité de Ptolémée, et à la conception du monde fini ayant pour limite la sphère des fixes et hiérarchisé ayant pour centre le Soleil, héritée des Pythagoriciens. Dès lors, est-elle à bon droit nommée « révolution copernicienne » selon l’expression consacrée ou bien doit-elle être (...) rigoureusement pensée comme réforme de l’astronomie ptoléméenne? La question engage la remise en chantier du concept de révolution scientifique. Celle-ci est-elle, selon son concept kuhnien, un changement de paradigme pour un groupe scientifique dans un domaine de recherche – auquel cas l’œuvre de Copernic serait une révolution scientifique en substituant au paradigme géocentrique de l’astronomie son paradigme héliocentrique? Ou bien est-elle, selon Kant qui a élaboré le premier son concept, une transformation dans la façon de penser, qui instaure une science – auquel cas cette œuvre serait bien plutôt une réforme scientifique, l’astronomie étant une science déjà instaurée dans l’Antiquité?

In a highly influential work, List and Pettit (Group Agency: The Possibility, Design, and Status of Corporate Agents, Oxford University Press, 2011) draw upon the theory of judgement aggregation to offer an argument for the existence of nonreductive group agents; they also suggest that nonreductive group agency is a widespread phenomenon. In this paper, we argue for the following two claims. First, that the axioms they consider cannot naturally be interpreted as either descriptive characterisations or normative constraints upon group judgements, (...) in general. This makes it unclear how the List and Pettit argument is to apply to real world group behaviour. Second, by examining empirical data about how group judgements are made by a powerful international regulatory board, we show how each of the List and Pettit axioms can be violated in ways which are straightforwardly explicable at the level of the individual. This suggests that group agency may best be understood as a pluralistic phenomenon, where close inspection of the dynamics of intragroup deliberation can reveal that what prima facie appears to be a nonreductive group agent is, in fact, reducible.

C'est à l'érudit jésuite américain Léo Sweeney que l'on doit de s'être intéressé le premier aux conditions de l'émergence du concept d'infini dans la théologie chrétienne ainsi qu'aux sources de ce concept dans l'antiquité. Un des grands mérites de Sweeney fut, dans un article paru en 1957, de mettre en évidence l'existence d'un groupe de penseurs actifs peu après 1241 et qui, confrontés à la question de savoir si l'essence de Dieu était infinie, avaient répondu par la négative, et étaient (...) même, semble-t-il, allés jusqu'à affirmer que l'essence divine était finie. Nous ne connaissons l'existence de ces quidam que par les allusions faites par des auteurs qui les citent afin de les réfuter. Sweeney en a donc conclu que les quidam étaient les «catalyseurs» de la doctrine classique de l'infini telle qu'elle allait prendre forme chez un Thomas d'Aquin et ses contemporains ou successeurs. Le problème se pose de savoir qui étaient ces énigmatiques quidam et quelle était la nature exacte de leurs doctrines. A la première de ces questions, laissée en suspens dans l'article de 1957, Sweeney vient récemment de proposer une tentative de solution précise, dans un ouvrage intitulé Divine Infinity in Greek and Medieval Thought: un auteur qui a très certainement défendu la thèse de la finitude de l'essence divine serait Guerric de Saint-Quentin. Le propos de cette note est simple: nous aimerions montrer, qu'à bien les lire, les textes de Guerric n'autorisent pas à lui imputer la doctrine de la finitude divine. Comme l'identification par Sweeney de Guerric comme un quidamdépend de sa reconstruction de la doctrine des quidam dans son article de 1957, il convient de commencer par là notre examen. (shrink)

'Beaucoup perçoivent, devant la progression de la possibilité pour l'individu d'affirmer sa singularité et sa volonté de bien-être, une progression de l'individualisme. Pour maintenir tant bien que mal un semblant de cohérence, ils sont alors obligés de minimiser, voire d'occulter, la progression de la solidarité dans le monde, aussi bien le développement des divers systèmes de protection sociale étatiques que le développement des aides interétatiques ou le développement des organisations non gouvernementales. Mais le concept d'individualisme ne décrit pas ce qui (...) effectivement se passe au niveau de l'individu, il ne fait que l'effleurer de son aile douloureuse et s'écraser contre la vitre du concept d'égoïsme. Il faut inventer un autre concept : ce sera l'individuité. Et alors tout devient plus cohérent. L'individuité, définie comme la désacralisation totale de tout groupe et la sacralisation à égalité de tout individu, est ce qui permet de rendre compte du fait que c'est justement parce que la civilisation se structure peu à peu autour de l'égo, que c'est justement parce qu'elle transfère peu à peu, des dieux aux individus, ses mouvements les plus centraux et ses perspectives les plus fondamentales, qu'elle fait alors croître sa capacité à générer de la solidarité et même de l'altruisme. Le regard humain, qui depuis toujours vacillait, à la fois se courbant vers le despotisme de sa terre et se perdant vers les mirages de l'au-delà, acquiert peu à peu la capacité d'enfin se stabiliser à hauteur d'humain, dans le regard de l'Autre. Vidant progressivement de leur substance les communautés identitaires au profit des individus qu'arbitrairement elles enclosent, déconstruisant progressivement les fausses transcendances au profit de l'autotranscendance de la conscience réflexive, faisant progressivement du Je le centre de l'univers, la civilisation se structure peu à peu autour du fait qu'il y a magnifiquement un nombre incommensurable de centres à l'univers, un par subjectivité. L'humanité n'avait toujours vécu qu'à l'ère des sacralités groupales, qu'à l'ère de la dialectique identitarisme-religion, et puis, d'abord par un frémissement il y a deux millénaires et demi, et se renforçant peu à peu au cours des siècles jusqu'à de nos jours entrer dans un vertige exponentiel, voilà qu'une nouvelle dynamique émerge qui renverse tout : l'individu s'émancipe. Une nouvelle ère anthropologique s'ouvre à nous, il fallait la nommer : l'ère de l'individuité sera, ici, peut-être ailleurs, son nom. Un nom est aussi un outil, il permettra de mieux conceptualiser ce changement, pour mieux l'accompagner, et pour l'accélérer. Car les forces réactionnaires sont là, puissantes, actives, qui le freinent. Le militarisme est l'archétype du vivre-ensemble tel que l'agençait l'ère des sacralités groupales, là où les individus ne sont que des fragments de groupes identitaires, d'insignifiantes munitions ne servant qu'à s'écraser, au mieux par terre, et le labour ainsi se fait, au pire contre celles des autres groupes identitaires, et la mort toujours triomphe : et ce monde affreux, bien qu'affreux, n'est pas facile à quitter, et le vivre-ensemble, bien que souffrant, ne se laisse pas facilement soigner, et le chemin sera alors encore long (peut-être même très long, mais peut-être pas tant que ça si l'on sait le penser) avant que chaque individu soit considéré comme un tout, avant que l'égalité ontologique remplace totalement les hiérarchies identitaires, avant que l'éthique du respect universel remplace totalement la morale sacrificielle, avant que l'humanité ait définitivement choisi entre l'individuité ou la guerre'."--Page 4 of cover.

Within this paper, we discuss Moral Distress Reflective Debriefs as a promising approach to address and mitigate moral distress experienced by healthcare professionals. We briefly review the empirical and theoretical literature on critical incident stress debriefing and psychological debriefing to highlight the potential benefits of this modality. We then describe the approach that we take to facilitating reflective group discussions in response to morally distressing patient cases (“Moral Distress Reflective Debriefs”). We discuss how the debriefing literature and other clinical ethics (...) activities influenced the development of our approach. In particular, we focus on the role of the clinical ethicist as a facilitator with particular emphasis on encouraging perspective-taking and nurturing ethical attunement in a supportive manner. We suggest that this approach reduces the narrowing effects of frustration and anger that are often reported when individuals experience moral-constraint distress. Finally, we provide an example of Moral Distress Reflective Debriefs, elucidating how this supportive process complements ethics consultation and can mitigate the negative effects of moral distress.

There has been increasing debate in recent years about the conceptualization of moral distress. Broadly speaking, two groups of scholars have emerged: those who agree with Jameton’s ‘narrow definition’ that focuses on constraint and those who argue that Jameton’s definition is insufficient and needs to be broadened. Using feminist empirical bioethics, we interviewed critical care nurses in the United Kingdom about their experiences and conceptualizations of moral distress. We provide our broader definition of moral distress and examples of data that (...) both challenge and support our conceptualization. We pre‐empt and overcome three key challenges that could be levelled at our account and argue that there are good reasons to adopt our broader definition of moral distress when exploring prevalence of, and management strategies for, moral distress.

Logique et existenceDeleuze à propos des « conditions du réel »Pour Deleuze, l’un des problèmes fondamentaux d’une théorie de la pensée est de savoir comment la pensée peut quitter la sphère du possible pour penser le réel, c’est-àdire pour penser l’existence elle-même. La position du réel semble être hors du concept. Des pré-kantiens comme Leibniz approchaient ce problème par le biais de la distinction entre vérités d’essence et vérités d’existence, alors que des post-kantiens comme Maimon l’approchaient par la distinction entre (...) les conditions de l’expérience possible et celles de l’expérience réelle. La logique classique définit la sphère du possible par trois principes logiques – l’identité, la non-contradiction et le tiers-exclu – et la présente étude examine les trois grandes trajectoires qui, dans cette histoire de la philosophie, ont tenté d’utiliser l’un de ces trois principes classiques pour pénétrer l’existence ellemême : 1) Leibniz (et les pré-kantiens) cherchait à étendre le principe de d’identité àl’existence entière ; 2) Hegel (et les post-kantiens) cherchait à étendre le principe de non-contradiction à la totalité de l’expérience ; et 3) le groupe des penseurs appelés de manière assez large « existentialistes » cherchait à étendre le principe du tiers-exclu à la totalité de l’existence. La conclusion examine les raisons pour lesquelles Deleuze a été fasciné par chacune de ces tentatives philosophiques pour « penser l’existence », tout en pensant néanmoins qu’elles ont toutes échoué ; et pourquoi aussi il a fini par développer sa propre réponse au problème en faisant appel à un principe de différence.Logica e EsistenzaLe ‘Condizioni del reale’ in DeleuzePer Deleuze, uno dei problemi fondamentali per una teoria del pensiero è: come può il pensiero abbandonare la sfera del possibile per pensare il reale, ossia, pensare l’esistenza stessa? La posizione del reale sembra essere fuori dal concetto. Prekantiani come Leibniz affrontano questo problema in termini di distinzione fra verità dell’essenza e verità dell’esistenza, mentre post-kantiani come Maimon affrontano il problema in termini di distinzione fra condizioni dell’esperienza possibile e condizioni dell’esperienza reale. La logica classica ha definito la sfera del possibile secondo tre principi logici – identità, non-contraddizione, terzo escluso – e questo saggio analizza tre grandi ‘parabole’ della storia della filosofia che hanno tentato di usare uno di questi tre principi della logica per penetrare l’esistenza stessa: (1) Leibniz (e i pre-kantiani) hanno tentato di estendere il principio di identità a tutta l’esistenza; (2) Hegel (ei post-kantiani) hanno tentato di estendere il principio di non-contraddizione a tutta l’esistenza; (3) il gruppo di pensatori (solo approssimativamente legati fra loro) chiamati “esistenzialisti” ha tentato di estendere il principio del terzo escluso all’esistenza. La conclusione analizza sia le ragioni per le quali Deleuze era affascinato da ciascuno di questi tentativi filosofici di “pensare l’esistenza” nonostante fosse convinto che essi avessero fallito, sia i motivi per cui egli in conclusione traccia la propria risposta al problema facendo appello al principio della differenza.

Il est plutôt rare qu’on rende compte dans une revue philosophique d’un manuel de physique théorique. Dans le cas du présent ouvrage, la chose n’est pas si incongrue puisque l’auteur, physicien québécois, n’est pas étranger aux questions philosophiques et s’est souvent mêlé des débats épistémologiques. En plus, son traité comporte plusieurs chapitres qui intéressent l’épistémologie de la physique tout en étant un manuel d’une envergure comparable aux classiques du genre en langue française, ceux de Cohen-Tannoudji, Messiah, Omnès ou Lévy-Leblond. On (...) y trouvera un exposé complet de l’appareil analytique de la mécanique quantique, des espaces de Hilbert de dimension finie à l’intégrale fonctionnelle de Feynman—avec quelques remarques sur la question délicate de la convergence, puisqu’on sait que l’intégrale de «chemins» n’a pas de justification mathématique «interne»—et au groupe de symétrie de l’hamiltonien pour la dynamique d’un système quantique dont l’évolution temporelle est décrite par l’équation de Schrödinger. Ces matières sont introduites avec force détails et le souci constant des applications, comme en témoigne le chapitre8 sur les solutions numériques et les méthodes d’approximation. Couvrant surtout la physique atomique et moléculaire sans aller jusqu’à la théorie des particules élémentaires et la théorie quantique des champs, l’ouvrage discute du problème de la mesure plus abondamment que le traité standard. C’est là d’ailleurs un des traits distinctifs de l’ouvrage et les chapitres6 sur l’interprétation de la mécanique quantique, 12sur l’opérateur densité et 21sur les corrélations à distance feront l’objet de mon analyse.

Austerity, by its very nature, imposes constraints by limiting the options for action available to us because certain courses of action are too costly or insufficiently cost effective. In the context of healthcare, the constraints imposed by austerity come in various forms; ranging from the availability of certain treatments being reduced or withdrawn completely, to reductions in staffing that mean healthcare professionals must ration the time they make available to each patient. As austerity has taken hold, across the United Kingdom (...) and Europe, it is important to consider the wider effects of the constraints that it imposes in healthcare. Within this paper, we focus specifically on one theorised effect—moral distress. We differentiate between avoidable and unavoidable ethical challenges within healthcare and argue that austerity creates additional avoidable ethical problems that exacerbate clinicians’ moral distress. We suggest that moral resilience is a suitable response to clinician moral distress caused by unavoidable ethical challenges but additional responses are required to address those that are created due to austerity. We encourage clinicians to engage in critical resilience and activism to address problems created by austerity and we highlight the responsibility of institutions to support healthcare professionals in such challenging times.

En 1983, un groupe de femmes japonaises francophiles, très intéressées par le féminisme français et les changements rapides de la vie des femmes en France depuis les années 1970, créent la Société Franco-japonaise des Études sur les Femmes. Le but est de promouvoir une meilleure compréhension entre les deux cultures et de développer des liens avec les Françaises sur un grand nombre de questions féminines. Le projet se révéla vite être un succès. Parmi les études entreprises par la Société, l’analyse (...) comparée de l’histoire des Françaises et des Japonaises, domaine très peu exploré alors, a suscité un vif intérêt chez les participantes. Cet article revient sur vingt années de réflexion, de recherche, et d’échange par un groupe d’historiennes non-professionnelles sur les relations entre histoire et expériences de vie personnelles. Il nous montre comment l’étude de l’histoire des femmes dans un contexte international peut être fructueuse et bénéfique, et combien une libre discussion collective, sans tabous, sur ce sujet peut éveiller ou approfondir la conscience féministe.

Europe: The Space and Time of ReflectionOn the Complutense Research Group La Europa de la Escritura.

Kleinschmidt's definition of the “Weltformenkreis” as the smallest systematical unit of affinity removes any danger of obliterating the type and at the same time opens a way for judging the superior taxonomic groups on principle differently from the subspecies of a “Formenkreis”.It is demonstrated that the characters of geographical subspecies are characters of apparent shaping, those of the species however are characters of construction and qualitative and autonomic ones. It is the type differentiating in quality that justifies the definition of (...) species. As the characters of type do not necessarily appear gradual and quantitative, but are qualitative, the types cannot be derived from one another, unless they are conceived by the common superordinate idea of the superior systematical category next in order.The distinct division of species is opposed to the hypothetical continuity of the pedigree, which cannot be explained by a consanguinity nor by an affinity based on reproduction. The pedigree, however, is an expression of the spiritual order of nature, in which the types appear as units hierarchically graduated and determined by entelechy, not by dead matter.Within the systematical units there is a creative evolution, steadily pursuing its aim and leading from the primitive stage to the differentiated one, beginning with a juvenile phase, which is followed by orthogenetic maturity and, finally, by the aged stage with its “detypification”. The adaptation to the environment may be also proved for the primitive forms and is an organic part of the whole design of the world for them as well as for the specialized and differentiated forms. — The formation of new types cannot be explained in a merely mechanical way; everywhere, even in the gens and genoms, we state ingenious modifications, which do not only bring about a reaction of a single modification to the whole, but operate from the whole. Since the origin of man, since the tertiary formation, the creation of species has completely ceased. There are only alterations of subspecific character.After a digressive treatise on the fundamental difference of man and animal in order to explain the type the superior systematical categories are characterized as spiritual realities. It is especially for the “genus” that a revision is necessary. The reality of the common origin of certain species within the genus is not based on reproduction , but on the superior totality comprising the species. Individuals can be conceived by the character of the species, species by the character of genus only. This is an evidence for the methodicalness of creative nature. It excludes any evolution of the genus “from bottom to top”, which is irregular, accidental or immediately formed by environment. From this we derive the comprehensive right of a natural system which now is more than mere classification.Kleinschmidt qui donne une définition du „Weltformenkreis” comme la plus petite unité d'affinité systématique, déjoue le danger d'oblitérer le type et offre, en même temps, la possibilité de juger les groupes taxonomiques supérieurs par principe différemment de la souspèce d'un „Formenkreis”.Nous démontrons que les caractères des souspèces géographiques sont des caractères du façonnement extérieur, tandis que ceux de l'espèce sont des caractères de la construction d'une manière qualitative et autonome. Le type différent en qualité justifie seulement la définition de l'espèce. Comme les caractères du type n'apparaissent pas nécessairement graduels et quantitatifs, mais sont au contraire, qualitatifs, les types ne se dérivent pas l'un de l'autre, à moins qu'ils ne soient compris par la commune idée supérieure du plus sublime groupe systématique.La division distincte des espèces s'oppose à la continuité hypothétique de la généalogie, qui ne s'explique pas par une consanguinité ni par une affinité se fondant sur la reproduction, mais qui est plutôt une expression du régime spirituel de la nature, dans lequel les types se présentent comme des unités rangées hiérarchiquement et réglées par l'entéléchie et non par la matière.Dans les unités systématiques il y a une évolution créatrice qui tend continuellement à son but et mène de la phase primitive à la phase différentiée commençant par un état juvénile, qui est succédé par la maturité orthogénétique et enfin par l'âge avec sa „détypification”. L'adaptation au milieu est démontrée pour les formes primitives et représente un élément organique du grand projet mondial pour elles aussi bien que pour les formes spécialisées et différentiées. — La formation de types nouveaux ne s'explique pas seulement d'une manière mécanique; partout, même dans les „genes” et les „genomes”, nous observons des transformations ingénieuses, qui ne sont pas seulement une réaction d'une modification particulière à l'ensemble, mais un effet de l'ensemble. Depuis l'origine de l'homme, depuis la période tertiaire la formation d'espèces est complètement finie. À présent il n'y a plus que des variations d'un caractère souspécifique. Après un traité digressif sur la différence essentielle de l'homme et de l'animal pour expliquer le type les groupes systématiques supérieurs sont caractérisés comme des réalités spirituelles. C'est surtout pour le genre qu'une révision est nécessaire. La réalité de la racine commune de certaines espèces dans le genre ne se fonde pas sur la reproduction , mais sur la totalité supérieure qui implique toutes les espèces. Des individus sont compris par le caractère d'espèce, des espèces seulement par le caractère de genre. C'est une preuve de la méthode de la nature créatrice. Elle exclut une évolution de genre „du bas en haut”, qui est irrégulière, faite par hasard ou formée directement par le milieu. De là nous dérivons le droit compréhensible d'un système naturel, qui est désormais plus qu'une simple classification. (shrink)

Militante et réflexive, l’histoire des femmes a aussi besoin d’exprimer ses doutes et ses inconforts. Rattrapée par l’actualité, la violence et nombre d’événements cruels et tragiques, par des incertitudes majeures vécues par l’ensemble du monde intellectuel, elle pose aujourd’hui en cet article collectif des interrogations et des inquiétudes. Ce travail à plusieurs (les participantes du Groupe d’histoire des femmes du CRH) cherche à mettre à plat ce qui actuellement se dérobe à notre connaissance, en partant de notions-clés souvent utilisées, comme (...) consentement, sexualité, écriture, patriarcat, etc. Chacune de ces notions est discutée à la lumière des brouillages actuels, des temporalités nouvelles, de l’avènement triomphant du corps marchandise, de la pauvreté grandissante, etc. (shrink)

Introducción: los accidentes son de las primeras causas de muerte a nivel mundial, por lo que la prevención de los mismos es una emergencia. Objetivo: valorar la repercusión de una intervención comunitaria en la disminución de peligros potenciales de accidentes en familias con niños de 0 a 18 meses. Métodos: se realizó un estudio cuasi experimental multietápico, con enfoques cuantitativo y cualitativo, entre enero de 2009 a junio de 2012. Se trabajó con 39 familias entre las que se produjeron nacimientos (...) en el periodo enero de 2008 a enero de 2010 de los Consultorios Médicos del Consejo Popular 26 de julio del Municipio Santo Domingo. Se efectuó una intervención por un grupo de trabajo comunitario conformado por integrantes del Círculo de interés "Prevención es Salud" y brigadistas de la Cruz Roja, liderados por la enfermera de la familia, se empleó para ello la Guía para Análisis de vulnerabilidades y capacidades de la Cruz Roja, modificada en su etapa I. Resultados: Post intervención se logró la reversión de vulnerabilidades en cuanto a capacidades, se manifestaron cambios favorables en los conocimientos y disminuyó significativamente el número de peligros potenciales en cada hogar. Conclusiones: Cuando se trabaja con familias con instrumentos sencillos y accesibles, y con el grupo de trabajo comunitario, se favorece la toma de conciencia sobre el problema en el entorno donde se generó. Introduction: accidents are one of the first causes of death worldwide, so their prevention is an urgency. Objective: assess the effect of a community intervention in the reduction of potential dangers of accidents in family with children aged from zero to 18 months. Methods: a multiage cuasi experimental study was carried out, with quantitative and qualitative approaches, from January 2009 to June 2012. The sample was taken from thirty-nine families who had children in the period ranging from January 2008 to January 2010 belonging to the family doctor´s house of the community called "26 de Julio" from Santo Domingo municipality. An intervention was carried out by a community group work composed by members of centers of interests called ¨Prevention is health¨ and members of the Red Cross led by the family nurse. It was necessary to ask a guide to analyze the vulnerabilities and capabilities of the Red Cross, modified in the first stage. Results: During the post intervention, it was possible to change the vulnerabilities in terms of capacities, favorable changes were present in the knowledge and the number of potential risks significantly decreased in each house. Conclusions: when families are approached with simple and accessible instruments, and with a community group work it is possible to make favorable changes in terms of awareness of the problem in the same place where it emerged.

On 8th August 2019, Secretary of State for Health and Social Care, Matt Hancock, announced the creation of a £250 million NHS AI Lab. This significant investment is justified on the belief that transforming the UK’s National Health Service (NHS) into a more informationally mature and heterogeneous organisation, reliant on data-based and algorithmically-driven interactions, will offer significant benefit to patients, clinicians, and the overall system. These opportunities are realistic and should not be wasted. However, they may be missed (one may (...) recall the troubled Care.data programme) if the ethical challenges posed by this transformation are not carefully considered from the start, and then addressed thoroughly, systematically, and in a socially participatory way. To deal with this serious risk, the NHS AI Lab should create an Ethics Advisory Board and monitor, analyse, and address the normative and overarching ethical issues that arise at the individual, interpersonal, group, institutional and societal levels in AI for healthcare.

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical reproductive (...) applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

This book considers the place and value of knowledge in contemporary society. “Knowledge” is not a self-evident concept: both its denotations and connotations are historically situated. Since the Enlightenment, knowledge has been a matter of discovery through effort, and “knowledge for its own sake” a taken-for-granted ideal underwriting progressive education as a process which not only taught “for” and “about” something, but also ennobled the soul. While this ideal has not been explicitly rejected, in recent decades there has been a (...) tacit move away from a strong emphasis on its centrality, even in Higher Education. The authors address the values that inform knowledge production in its present forms, and seek to identify social and cultural factors that support these values.Against the background of increasingly restrictive conditions of academic work, the first section of this volume offers incisive critiques of Higher Education, with examples drawn from Australia and New Zealand. The second group of chapters considers how academics have viewed, and have tried to adapt to, present circumstances. The third section comprises papers that consider epistemological issues in the generation and promulgation of knowledge. The chapters in this volume are indicative of the work that needs to be done so that we can come to comprehend – and perhaps try and improve – our relationship to learning and knowledge in the 21st Century.This timely book will be of particular interest to workers in higher education; it should also inform and challenge all those who have concerns for the future of the intellectual life of our civilization.

The Routledge Handbook of Critical Pedagogies for Social Work traverses new territory by providing a cutting-edge overview of the work of classic and contemporary theorists, in a way that expands their application and utility in social work education and practice; thus, providing a bridge between critical theory, philosophy, and social work. Each chapter showcases the work of a specific critical educational, philosophical and/or social theorist including: Henry Giroux, Michel Foucault, Cornelius Castoriadis, Herbert Marcuse, Paulo Freire, bell hooks, Joan Tronto, Iris (...) Marion Young, Karl Marx, Antonio Gramsci and many others to elucidate the ways in which their key pedagogic concepts can be applied to specific aspects of social work education and practice. The text exhibits a range of research-based approaches to educating social work practitioners as agents of social change. It provides a robust and much needed, alternative paradigm to the technique-driven ‘conservative revolution’ currently being fostered by neoliberalism in both social work education and practice. The volume will be instructive for social work educators who aim to teach for social change, by assisting students to develop counter-hegemonic practices of resistance and agency, and reflecting on the pedagogic role of social work practice more widely. The volume holds relevance for both postgraduate and undergraduate/qualifying social work and human services courses around the world. (shrink)

This paper presents the place of dreaming in Merleau-Ponty’s thought. It elicits the view of dreaming developed in three seminal texts:Phenomenology of Perception, the passivity fragment from the Themes from the Lectures at the College de France, and The Visible and the Invisible. In each of these texts, Merleau-Ponty releases dreaming from the secondary status conventionally granted to it in relation to waking perception, and maintains, instead, the integrity of the phenomenon as an authentic mode of experience. At the same (...) time, he insists upon the interrelatedness of dreaming and waking by positing for both the lived body as a common ground that precludes dichotomization. Merleau-Ponty’s elevation of the imaginary in general, and dreaming in particular, is especially relevant to contemporary psychology in its quest for theoretical foundations that will accommodate the full spectrum of psychological phenomena.

Dans ce texte les auteurs explorent les potentialités du recours au dispositif groupal et à l’introduction de la médiation par les images dans la prise en charge de jeunes requérants d’asile. La clinique liée aux migrations contemporaines nous confronte à un véritable défi concernant la prise en soin de sujets qui appartiennent à des cultures différentes, parlent des langues diverses et sont porteurs de traumatismes qui se révèlent à la fois singuliers et pluriels. À travers l’exemple d’un groupe à médiation (...) Photolangage® avec des ex-mineurs non accompagnés, l’article décrit comment le modèle psychanalytique de groupe peut être un dispositif original pour la compréhension et le traitement d’une telle clinique.

There are few evidence-based interventions that have been developed that mitigate the negative effects of moral distress. Group debriefing is one approach that some clinical ethicists have adopted as a response. However, there is very little academic literature or empirical research that identifies best practices and approaches to debriefing as a response to moral distress. Our aim at the 2020 UnConference was to share our different approaches to debriefing with other clinical ethicists to identify best practices or guiding principles to (...) enhance our respective approaches and meet the needs of healthcare professionals. In this article we share an overview of our respective approaches, reflect on our discussion with other clinical ethicists and healthcare professionals, and propose foundations to move debriefing forward as an intervention to address moral distress in the field of clinical ethics.
