In 1952, Heinrich Scholz published a question in The Journal of Symbolic Logic asking for a characterization of spectra, i.e., sets of natural numbers that are the cardinalities of finite models of first order sentences. Günter Asser in turn asked whether the complement of a spectrum is always a spectrum. These innocent questions turned out to be seminal for the development of finite model theory and descriptive complexity. In this paper we survey developments over the last 50-odd years pertaining to (...) the spectrum problem. Our presentation follows conceptual developments rather than the chronological order. Originally a number theoretic problem, it has been approached by means of recursion theory, resource bounded complexity theory, classification by complexity of the defining sentences, and finally by means of structural graph theory. Although Scholz' question was answered in various ways, Asser's question remains open. (shrink)

We study the extension of dependence logic \ by a majority quantifier \ over finite structures. We show that the resulting logic is equi-expressive with the extension of second-order logic by second-order majority quantifiers of all arities. Our results imply that, from the point of view of descriptive complexity theory, \\) captures the complexity class counting hierarchy. We also obtain characterizations of the individual levels of the counting hierarchy by fragments of \\).

The interventionist account of causation offers a criterion to distinguish causes from non-causes. It also aims at defining various desirable properties of causal relationships, such as specificity, proportionality and stability. Here we apply an information-theoretic approach to these properties. We show that the interventionist criterion of causation is formally equivalent to non-zero specificity, and that there are natural, information-theoretic ways to explicate the distinction between potential and actual causal influence. We explicate the idea that the description of causes should be (...) proportional to that of their effects. Then we draw a distinction between two ideas in the existing literature, the range of invariance of a causal relationship and its stability. The range of invariance is related to specificity and range of causal values. Stability concerns the effect of additional variables on the relationship between some focal pair of cause and effect variables. We show how to distinguish and measure the direct influence of background variables on the effect variable, and their influence on the relationship between the focal cause and the effect variable. Finally, we discuss the limitations of the information-theoretic approach, and offer prospects for complementary approaches. (shrink)

Yoga et spiritualité est le témoignage émerveillé mais lucide d'un voyageur en quête des valeurs essentielles. Bien avant que ne déferle sur l'Occident désorienté la mode de la route et du périple oriental, Arnaud Desjardins a voulu délaisser les voies touristiques afin d'écouter battre le coeur de l'Inde. C'est cette pulsation qu'il tente ici de nous livrer, la face cachée d'une Inde encore fervente, enracinée dans les millénaires de tradition. L'auteur procède du même coup à une mise au point (...) et aide ses lecteurs à se frayer un chemin à travers le fatras d'idées reçues, de contresens et de présupposés à propos du "Yoga" et des "mystiques orientales". Carnet de bord essentiel pour comprendre le cheminement intérieur d'Arnaud Desjardins, cet ouvrage donne quelques clefs fondamentales et constitue un document limpide sur une société bien mal connue de nous, et aujourd'hui plus que jamais menacée.

En expliquant comment les forces de l’ordre se dotent d’uniformes spécifiques au cours du xixe siècle, il s’agit de comprendre la signification de cet objet. Au-delà de l’utilité pratique du costume, qui peut faire débat, policiers et gendarmes affichent une prestance militaire qui renforce leur prestige. Mais ils montrent aussi qu’ils travaillent en toute transparence, en assumant leurs actes et en se plaçant au service du public. Ils prouvent enfin leur valeur en engageant des dépenses vestimentaires qui deviennent un gage (...) de respectabilité. S’il constitue un enjeu symbolique fort, l’uniforme évolue dans le sens d’une plus grande simplicité fonctionnelle au cours du xixe siècle, s’adaptant dans une certaine mesure à la mode masculine.

Background: Informed consent in clinical research is mandated throughout the world. Both patient subjects and investigators are required to understand and accept the distinction between research and treatment.Aim: To document the extent and to identify factors associated with therapeutic misconception in a population of patient subjects or parent proxies recruited from a variety of multicentre trials .Patients and methods: The study comprised two phases: the development of a questionnaire to assess the quality of informed consent and a survey of patient (...) subjects based on this questionnaire.Results: A total of 303 patient subjects or parent proxies were contacted and 279 questionnaires were analysed. The median age was 49.5 years, sex ratio was 1 and 61% of respondents were professionally active. Overall memorisation of the oral or written communication of informed consent was good , and satisfaction with the process was around 70%. Therapeutic misconception was present in 70% of respondents, who expected to receive better care and ignored the consequence of randomisation and treatment comparisons. This was positively associated with the acuteness and severity of the disease.Conclusion: The authors suggest that the risk of therapeutic misconception be specifically addressed in consent forms as an educational tool for both patients and investigators.

In this article, the authors, as researchers, are part of a clinical approach to psychoanalytic orientation in education sciences, questioning their research approach during an investigation on the expulsion from classrooms in secondary school in France. Trying to compare themselves to different types of collaborative research, they analyse the modalities of relationship they tried to implement during this research ‘with’ subjects, including teenagers students they have interviewed.

In recent years, scholars have shown the fruitfulness of linking Peirce’s speculative rhetoric with the rhetorical tradition—which can be broadly construed as the art, time and again rediscovered and refined, of rendering discourses eloquent and persuasive. They have suggested many ways in which the historical development of rhetoric sheds light on the third branch of Peirce’s semiotic and further pointed out many contributions Peirce makes in turn to the field of rhetoric. However, with the notable exception of Colapietro, these authors (...) have focused almost exclusively on questions of method and discovery. They have... (shrink)

Arnaud Martin Le 29 août 2018, le président du gouvernement espagnol Pedro Sánchez annonça la création d’une commission de la vérité sur les crimes commis durant la guerre civile et la dictature franquiste. Ainsi devait prendre officiellement fin la politique d’impunité et d’amnésie politique imposée au peuple espagnol au lendemain de la mort du général Franco par la loi du 15 octobre 1977, confirmée trente ans plus tard par la loi du 26 décembre 2007, comme contrepartie des mesures d’amnistie (...) prises en faveur des condamnés politiques et comme prix à payer pour assurer la réussite du processus consensuel de transition démocratique. La mémoire historique qui avait été refusée aux Espagnols allait pouvoir devenir réalité. La commission s’inscrit de façon originale dans la logique de la justice transitionnelle. En effet, l’élaboration de la vérité historique annoncée par Pedro Sánchez a pour but, non pas d’assurer la transition démocratique et la pacification d’une société postconflictuelle, mais de prévenir la « déconsolidation » démocratique à laquelle pourraient conduire la non-reconnaissance des torts subis par les victimes du franquisme et l’impossibilité de l’Espagne – notamment de la droite – à tourner la page du franquisme.

To be able to make “change” happen in the lives of patients entrusted to his care, Watzlawick says he tried to produce a theory about it. He was forced to acknowledge that the mechanisms of change resist systematization and, therefore, all wishes to elicit them as well.Well-being is to therapy what discovery is to thought and the event is to History: the position – unforeseen, unforeseeable – in reality of what did not hitherto exist. And heuristics would be, if not (...) a science, since there could be no science of change, then at least the name given to reflection on its mystery. (shrink)

Le présent article est le fruit d’une recherche qualitative auprès de l’ensemble des acteurs concernés par le dispositif « Espace de rencontre » ( er ) en France. Ce dispositif tant judiciaire que répondant aux nouvelles aspirations sociales autour de la famille vient soutenir le lien parent-enfant dans le cadre de séparations conflictuelles ou en cas d’incapacité de l’un des parents d’accueillir son ou ses enfants. Cette recherche, conduite entre 2017 et 2020 au sein de douze structures, visait à mieux (...) appréhender les pratiques en er, à identifier tant l’intérêt que les limites du dispositif et à faire émerger de nouveaux questionnements sur le maintien des liens filiaux dans des situations complexes. Le vécu des parents, enfants et professionnels concernés y a été recueilli par des chercheurs issus des sciences humaines et sociales. Si cette mesure socio-judiciaire est bien admise par une majorité des usagers, la manière dont les enfants, eux, vivent les rencontres reste questionnante. (shrink)

Several authors have argued that causes differ in the degree to which they are ‘specific’ to their effects. Woodward has used this idea to enrich his influential interventionist theory of causal explanation. Here we propose a way to measure causal specificity using tools from information theory. We show that the specificity of a causal variable is not well-defined without a probability distribution over the states of that variable. We demonstrate the tractability and interest of our proposed measure by measuring the (...) specificity of coding DNA and other factors in a simple model of the production of mRNA. (shrink)

This wide-ranging book examines the new dynamics of corporate social responsibility and the impact they have had on the transformation of business corporations. Written by an international group of distinguished experts in management and organization studies, economics and sociology, the book leads one to theoretically and practically rethink CSR, a movement that has developed into a strong and rich institutional domain since the mid 1990s. Through 14 chapters, the book shows the complexity, diversity and progression of the institutional work performed (...) by a large number of individual and organizational actors in specialized networks to develop this strategic field. Central to this book are: the core issues associated with the field of CSR; recent advances in the development, dissemination and implementation of public and private standards of social responsibility; the pressing challenges of developing sustainable strategies of value creation in the face of global warming and underdevelopment; and finally, examples of how CSR has been implemented and institutionalized within business organizations with special attention to the role played by a variety of social actors in organizational change. Conceived as a movement, corporate social responsibility spearheads a transformation project challenging traditional and outmoded forms of corporate governance that frequently pose troublesome ethical issues. From this standpoint, Corporate Social Responsibility and Corporate Change will serve as a reference point for academics, researchers, managers and practitioners. (shrink)

Cet article documente la pratique du plan dans les relations entre hommes, à savoir ces rencontres rapides, à but sexuel principalement et en général non répétées. Le matériel mobilisé résulte de trente entretiens semi-directifs. Le plan correspond souvent à une dissociation marquée entre le courant sensuel et le courant tendre, au sens freudien, et présente donc un intérêt pour approfondir la compréhension de cette dualité. L’article observe les prises de contact virtuelles, les lieux des plans et la possibilité de penser, (...) ou de ne pas penser, le plan, d’en refouler le souvenir. Les affects éprouvés dans la rencontre de l’autre comme l’absence d’affect ( désaffectation ) sont alors analysés aux côtés de la question de la sociabilité et des impressions d’inquiétante étrangeté.

Cet article explore plusieurs moutures de la philosophie historique de Nietzsche, depuis ses réflexions d’adolescent, où les réflexions génétiques sont encore inscrites dans une méditation d’ordre éthico-théologique, à la généalogie proprement dite, où l’étude de la provenance des valeurs prétend congédier toutes les autres formes d’histoire de la morale, que ce soit la microhistoire psychologique des moralistes français (La Rochefoucauld), l’histoire conjecturale des utilitaristes (Mandeville) ou l’histoire évolutionniste qui déduit la morale de l’adaptation (Spencer). Ainsi, en vertu de l’activité d’autodépassement (...) perpétuel et d’antagonisme incessant qui caractérise la volonté de puissance, Nietzsche s’emploie à faire la critique des autres formes de philosophies de l’histoire pour imposer sa « morphologie de la volonté de puissance », et il s’efforce en outre, tout au long de son propre itinéraire intellectuel, de lutter aussi contre lui-même, dans la mesure où les alliances qu’il avait contractées auparavant le retenaient d’être pleinement original.

Running head: Implicit sequence learning ABSTRACT Can we learn without awareness? Although this issue has been extensively explored through studies of implicit learning, there is currently no agreement about the extent to which knowledge can be acquired and projected onto performance in an unconscious way. The controversy, like that surrounding implicit memory, seems to be at least in part attributable to unquestioned acceptance of the unrealistic assumption that tasks are process-pure, that is, that a given task exclusively involves either implicit (...) or explicit knowledge.

Arnaud Milanese | : La philosophie pratique de Hobbes est problématique parce que son déterminisme ne semble pas permettre une théorie de l’action : comment penser l’imputation des actes, si l’on soutient que le libre-arbitre n’existe pas ? 1) Son analyse se construit à travers la critique de la théorie scolastique du libre arbitre (dans la controverse avec Bramhall), et, à cette fin, Hobbes semble puiser dans l’analyse d’Aristote pour y reprendre sa distinction entre actions volontaires et involontaires. 2) (...) Mais il ne peut penser cependant la spécificité des actions humaines, comme d’Aristote, par la contingence. 3) Il ne lui reste alors, pour penser l’imputation dans une ontologie déterministe, qu’à constituer une conception de l’individualité de l’agent qui repense le motif aristotélicien de la détermination intérieure à agir, mais sans libre-arbitre ni contingence. 4) Si les difficultés théologiques subsistent, c’est parce que, pour Hobbes, aucune philosophie ne peut résoudre les mystères de la foi. | : The hobbesian philosophy of action is problematical because his determinism seems unable to frame a theory of action : how could it be possible to conceive imputation of actions, if free will does not exist ? 1) This analysis is built on a criticism of scholastic theory of free will (in controversy with Bramhall), and, to this end, Hobbes seems to draw in the aristotelian analysis and makes use of his distinction between voluntary and involuntary actions. 2) But however, he cannot conceive the specificity of human actions the same way Aristotle did, that is, by the concept of contingency. 3) So, the only remaining way of thinking imputation in his determinist ontology seems to suppose a certain conception of the individuality of agents, and to rethink this way the aristotelian concept of inner determination to act, but without free will nor contingency. 4) Theological difficulties remains, of course, but only because, according to Hobbes, philosophy cannot solve the mysteries of faith.

This article argues that Brentano’s classification of mental phenomena is best understood against the background of the theories of natural classification held by Auguste Comte and John Stuart Mill. Section 1 offers a reconstruction of Brentano’s two-premise argument for his tripartite classification. Section 2 gives a brief overview of the reception and historical background of the classification project. Section 3 addresses the question as to why a classification of mental phenomena is needed at all and traces the answer back to (...) Mill’s view that psychological laws are class-specific. Section 4 and 5 connect the second premise of Brentano’s argument to Comte’s principle of comparative likeness and Mill’s insistance that class membership is determined by the possession of common characteristics. And section 6 briefly discusses the evidence Brentano provides for the first premise. (shrink)

Programmed cell death (PCD) in unicellular organisms is in some instances an altruistic trait. When the beneficiaries are clones or close kin, kin selection theory may be used to explain the evolution of the trait, and when the trait evolves in groups of distantly related individuals, group or multilevel selection theory is invoked. In mixed microbial communities, the benefits are also available to unrelated taxa. But the evolutionary ecology of PCD in communities is poorly understood. Few hypotheses have been offered (...) concerning the community role of PCD despite its far-reaching effects. The hypothesis we consider here is that PCD is a black queen. The Black Queen Hypothesis (BQH) outlines how public goods arising from a leaky function are exploited by other taxa in the community. Black Queen (BQ) traits are essential for community survival, but only some members bear the cost of possessing them, while others lose the trait In addition, BQ traits have been defined in terms of adaptive gene loss, and it is unknown whether this has occurred for PCD. Our conclusion is that PCD fulfils the two most important criteria of a BQ (leakiness and costliness), but that more empirical data are needed for assessing the remaining two criteria. In addition, we hold that for viewing PCD as a BQ, the original BQH needs to include social traits. Thus, despite some empirical and conceptual shortcomings, the BQH provides a helpful avenue for investigating PCD in microbial communities. (shrink)

Fluorescence imaging has become an indispensable tool in cell and molecular biology. GFP‐like fluorescent proteins have revolutionized fluorescence microscopy, giving experimenters exquisite control over the localization and specificity of tagged constructs. However, these systems present certain drawbacks and as such, alternative systems based on a fluorogenic interaction between a chromophore and a protein have been developed. While these systems are initially designed as fluorescent labels, they also present new opportunities for the development of novel labeling and detection strategies. This review (...) focuses on new labeling protocols, actuation methods, and biosensors based on fluorogenic protein systems. (shrink)

À travers des actes comme défiler, prêter serment, communier, et leurs mises en scène ritualisées, orchestrées par les détenteurs du pouvoir politique, l'objectif est de rassembler les assujettis sociaux et de leur administrer une double preuve, celle du bien fondé de leur obéissance au pouvoir et corollairement de leur harmonieuse association. Les cérémonies ritualisées visent à susciter une exaltation collective, à faire monter l'intensité émotionnelle tout en donnant à voir un idéal d'unité harmonieuse de la société, dans les mises en (...) scène jouées. Le but de cet article est de montrer comment les gouvernants ont toujours su, à travers les époques, créer des cérémonies rituelles pour mobiliser les individus, pour les conditionner, de façon à les faire adhérer en actes aux desseins du pouvoir politique, par une participation pleine et entière de l'âme et du corps.Through actions like scrolling, oath, communion, and their ritualized stagings, orchestrated by the holders of political power, the objective is to bring together social and subject to administer a double proof of the soundness of their obedience to authority and a corollary of their harmonious association. Ritualized ceremonies designed to elicit a collective exaltation, to raise the emotional intensity while providing an ideal view of harmonious unity of society, in the staging played. The purpose of this article is to show how governments have always known, through the ages, creating rituals to mobilize individuals to condition, so join them in the action plans of the political power through participation full of soul and body.
