Several results about the game of cops and robbers on infinite graphs are analyzed from the perspective of computability theory. Computable robber-win graphs are constructed with the property that no computable robber strategy is a winning strategy, and such that for an arbitrary computable ordinal \, any winning strategy has complexity at least \}\). Symmetrically, computable cop-win graphs are constructed with the property that no computable cop strategy is a winning strategy. Locally finite infinite trees and graphs are explored. The (...) Turing computability of a binary relation used to classify cop-win graphs is studied, and the computational difficulty of determining the winner for locally finite computable graphs is discussed.

In the vertex pursuit game of cops and robbers on finite graphs, the cop has a winning strategy if and only if the graph admits a dominating order. Such graphs are called constructible in the graph theory literature. This equivalence breaks down for infinite graphs, and variants of the game have been proposed to reestablish partial connections between constructibility and being cop-win. We answer an open question of Lehner about one of these variants by giving examples of weak cop-win graphs (...) which are not constructible. We show that the index set of computable constructible graphs is Π11 hard and the index set of computable constructible locally finite graphs is Π40 hard. Finally, we give an example of a computable constructible graph for which every dominating order computes 0″. (shrink)

Since antiquity many philosophers and grammarians were looking for what is “behind” the particular grammars, for something like “the unchangeable principles common to all languages”. Even limitingourselves to the most concrete aspects of such a general grammar, we may ask whether there is something realizable among the risky hipotheses and the vague projects.In this paper we do not try to discover something more or less hidden in the particular grammars, but to show, in a very general way, some directions for (...) constructing, eventually, an universal grammar. Four approaches are mentioned:(1) artificial universal languages like Esperanto,(2) systems of automatic analysis of a language,(3) programming languages,(4) the first-order systems of logic.It is shown how those approaches (and the experiences acquired in working with them might be combined; but wether this combination produces interesting results and brings us nearer to an universal and rational grammar of our computerized epoch is an open question, which can be answered only by practical experience.

Leibniz construit, teste et vérifie sans cesse la pertinence et la cohérence de sa philosophie en la rapportant aux conclusions des autres disciplines. Cette méthode heuristique nourrit son dialogue avec les sciences mathématiques et physiques; moins connus, les enjeux révélés par la réforme moderne de la médecine et la chimie suscitent une interrogation sur la vie et la qualité. Ces sciences expérimentales s'avèrent en effet cruciales pour une philosophie de la nature qui cherche à concilier le mécanisme et le finalisme (...) à travers les concepts d'entéléchie et de monade. Elles obligent en outre à préciser la logique de l'expérience, la fonction de la raison, le statut des principes explicatifs (loi, cause, éléments, analogie). Enfin, elles exigent un fondement qui permette de rapporter les phénomènes organiques à leur véritable origine: la vie. Ce programme se réalise de façon systématique dans la controverse qu'entretiennent Leibniz et Stahl au sujet d'une philosophie de la nature capable de prendre acte des découvertes modernes de la médecine et de la chimie, tout en fondant ces connaissances sur une théorie générale de la substance et de la vie.

An increase in the number of companies that publish corporate social responsibility (CSR) statements, and a rise in their ‘sustainability’ research, reflects a growing acceptance that broad ethical considerations are key for any type of company. However, little is known about how companies consider moral objectives for their research and development (R&D) activities, or the basis upon which these activities are chosen. This research involves qualitative investigation into Responsible Research and Innovation (RRI) in the Information and Communication Technology (ICT) industry, (...) comprising 30 in-depth, pan-European interviews with key personnel in the industry, and focus groups with employees at 14 different companies. Through investigation of the ‘responsible’ activities these companies currently undertake, we shed light on the types of moral goals they set and their underlying ethical standpoints. By reviewing both the responsible innovation and sustainability discourses, and presenting phenomenological evidence, we demonstrate that companies have adopted some aspects of RRI, even though it might not be recognised as such. Our findings indicate that these innovators recognise some of the ethical and societal concerns associated with their activities but their approach is often piecemeal; primary focus is upon the most immediate issues and on legal compliance, to the detriment of broader societal issues and wider challenges. We recommend explicit mechanisms that draw upon established ethical thought and practical academic work to improve companies' abilities to carry out their sustainability activities, and incorporate them into a responsible business strategy. We conclude with recommendations for innovators, corporate research and development, and policy. (shrink)

Both Stahl and Leibniz worked out conceptions of the organism that diverged significantly from the mechanistic models involved in the Cartesian dualism of soul and body. In the polemics which developed in 1709-1710 concerning Stahl's Theoria medica vera , Leibniz focused his attacks on what he considered a paralogistic theory of the soul; he wondered in particular how such an abstruse metaphysics could be reconciled with the scientific analysis of vital phenomena. Contrary to Stahl, Leibniz would defend (...) the view that the sufficient reason of organisms at the phenomenal level depends on an integrative combination of specific mechanisms; but the soul conceived as an entelechy needs to be called upon to account for the functional integration of the whole at the substantive level. Thus, the psychic and the somatic would involve a joint rationality unfolding in analogical and expressive relationships. However, both domains would require the use of separate analytic methodologies in any attempt at explaining those relationships. (shrink)

La vieillesse constitue une pierre de touche pour toute théorie médicale : elle oblige à rendre raison de la temporalité à l’œuvre dans la vie. Aux yeux de Stahl, les iatromécaniciens méconnaissent la dimension temporelle de l’organisme ; en particulier, ils en ignorent la périodicité. Comprendre la vieillesse suppose donc la critique de la représentation linéaire du temps organique, que développe la mécanique et qui réduit le vivant au seul composé physique et chimique. Il reste alors à trouver la (...) cause de la périodicité organique : sur ce point, Georg Ernst Stahl critique Thomas Sydenham, qui reconnaît certes la périodicité du vivant mais nie la possibilité d’une médecine étiologique. Pour sa part, le médecin de Halle cherche à rendre compte du vieillissement en lien avec les actions organiques fondamentales : le tonus, la circulation, l’excrétion, la sécrétion. (shrink)

P. J. G. Cabanis fut un des juges du premier Mémoire sur l’influence de l’habitude sur la faculté de penser du jeune Biran, lecteur précoce et attentif des Rapports du physique et du moral de l’homme. Dans ses écrits comme dans sa correspondance avec le médecin idéologue, Biran mène une critique sévère de la pensée de Cabanis qui dément l’hypothèse d’un « épisode matérialiste » de la pensée de Biran. En ramenant les facultés intellectuelles à la sensibilité physique, en élargissant (...) la juridiction propre au vivant au fonctionnement de l’esprit lui-même, le « matérialisme organique » de Cabanis représente l’application détournée du principe de Stahl dans un système matériel et mécanique. Enfin l’auteur souligne ce que devient dans le biranisme la découverte majeure faite par Cabanis de la sensibilité interne inconsciente et de son influence sur les facultés de l’esprit : point aveugle de notre existence, l’intériorité affectible ne peut être circonscrite ni par la réflexion ni par la représentation.

"Au cœur de la Révolution scientifique, philosophes et naturalistes tentent de concevoir les modèles les plus aptes à rendre compte du vivant. Les schèmes hérités de l'Antiquité médicale et philosophique sous-tendent encore les théories originales de Van Helmont et de Harvey. Si le mécanisme s'instaure avec le modèle de l'animal-machine chez Descartes, les audaces et les limites du projet cartésien infléchiront toute démarche ultérieure, comme en témoigne la notion spinoziste d'intégration corporelle. Gassendi suggère, pour sa part, d'associer la modélisation mécaniste (...) et la téléologie immanente des processus. Les néo-platoniciens More et Cudworth évoquent le 'principe hylarchique' ou la 'nature plastique', afin de traduire, por delà les insuffisances du mécanisme, l'émergence des organisations vitales. Lorsque le débat se transpose aux microstructures, Malpighi promeut l'analyse physiologique selon le modèle de 'petites machines' diversement combinées et emboîtées ; Glisson attribue la perception et la réactivité aux fibres élémentaires. Les phénomènes de la génération, que l'on a d'abord expliqués par l'épigenèse, s'interprètent principalement en termes de préformation et de préexistence des germes. Mais, à l'encontre de toute construction hypothétique, Locke privilégie une médecine limitée à l'observation des seuls phénomènes vitaux. La critique de mécanisme suscite en outre les modèles 'animistes' de Perrault et de Stahl. En une remarquable tentative, Leibniz repense alors les concepts fondamentaux de la théorie physiologique et suggère les voies d'analyse pur une science de l'organisme'."--taken from back cover.

In lieu of an abstract, here is a brief excerpt of the content:120 A WORD ON BEHALF OF DEMEA Little attention has been given to the a priori argument for God's existence espoused by Demea in Hume's Dialogues concerning Natural Religion. This circumstance is neither surprising nor unjustified. Given Hume's well-known theological sympathies, certainly no one would be tempted to regard Demea as Hume's spokesman. Demea's argument plays so small a role in the Dialogues as to suggest that Hume does (...) not take it at all seriously. He may present it only to establish that he is aware of alternative arguments for God's existence, but thinks them even less successful than the design argument and hence undeserving of extensive critique. Yet, if a philosopher criticizes an argument he deems unworthy of respect, he should still provide sound, not spurious, reasons for rejecting it. This is exactly what D. C. Stove has argued that Hume fails to do in Part IX of the Dialogues, assuming, as is generally done, that the speeches of Cleanthes and Philo present reasoning that Hume would personally endorse. Stove argues that most of the criticisms of Demea's argument are "extremely defective, and that they even include an inconsistency" (Stove, p. 300). This contention has been challenged by Donald Stahl, who has published a succinct point by point rebuttal of Stove's contentions.3 The Stove-Stahl controversy only deals with the reasoning presented in paragraphs 5, 6, 7, and 10 of Part IX because those are the contentions Stove attacks. He has "nothing to say against" the criticisms presented in paragraphs 8 and 9, which he assumes will be generally agreed to be 121 less important than the others (Stove, p. 308). He totally ignores the argument of paragraph 11. However, I am not convinced that the criticisms of these paragraphs are less important and I do have something to say against them. Consequently, instead of intervening directly on either side of the dispute between Professors Stove and Stahl, I shall attend principally to the argumentation of paragraphs 8, 9, and 11. I shall (1) summarize Demea's argument, (2) argue for the significance of the criticisms of paragraphs 8-9, (3) examine those criticisms, and (4) assess the role of Philo's concluding remarks in paragraphs 10-11. 1. Demea's Argument Early on Hume has Demea speak so obviously inconsistently as to make the reader wonder whether this character is supposed to think at all about the implications of the claims he espouses. At the beginning of Part II, he proclaims that God's existence is surely not at issue, since no one of common sense... ever entertained a serious doubt with regard to a truth so certain and self-evident." The nature of God is the only proper object of theological inquiry, and that is "altogether incomprehensible and unknown to us" (D 141)! Given such a radically apophatic position (Hume calls it "mystical"), it is hardly surprising that the sceptical Philo readily concurs, once he specifies that he takes 'God' to mean just "the original cause of this universe (whatever it be)" (D 142). But Demea immediately buttresses his alleged self-evident truth by appealing to the authority of Father Malebranche and the whole tradition of Christian theology, apparently oblivious to the impropriety of 122 supporting an indubitable truth by citing authorities (D 141-142). Further, scarcely more than a page later, after Cleanthes has sketched out the design argument, this same Demea is horrified that Cleanthes gives no abstract arguments or a priori proofs and calls for a "demonstration of the being of a God" (D 143). When, in Part IX, Demea himself undertakes to provide the "simple and sublime argument a priori" (D 188) he expected from Cleanthes, he characterizes the argument as "the common one," which suggests he is more engaged in paraphrasing authority than in thoughtfully arguing. The argument, in fact, as has been generally recognized, closely follows one given by Samuel Clarke in the Boyle Lectures of 1704. 5 Demea begins by assuming that "whatever exists must have a cause or reason of its existence," (D 188) since nothing can cause itself to exist. He then states a dilemma: in tracing the... (shrink)

This study examined the relationship between unethical employee behavior and the dimensions of the Ethical Climate Questionnaire (ECQ). In order to explore the relationship between the dimensions of the ECQ and unethical behavior, the factor structure of five previously identified empirical models and the hypothesized nine-dimension model for the ECQ was tested with a confirmatory factor analysis. The analysis revealed that the hypothesized nine-dimension model provided as good or even better fit to the data than the five empirically derived models. (...) Therefore, the nine-dimensional model was used to examine the criterion-related validity of the ECQ. The results demonstrated that the nine ethical climate dimensions were correlated with some of the unethical behaviors examined in this study, but not others. However, the results clearly demonstrated that most of the ethical climate dimensions were significantly related to an aggregate measure of unethical behavior. It was suggested that these results might account for the differences in previous studies on the criterion-related validity of the ECQ. The results also replicated a previous report that the association between unethical behavior and ethical climate is stronger in organizations that do not have a code of ethics. Finally, a difference was observed in the ethical climates for organizations with a code of ethics and organizations without a code of ethics. (shrink)

Au début du XVIIIe siècle, une querelle éclate entre deux chimistes français à propos de la fabrication artificielle du fer. C’est en fait un conflit entre une interprétation mécaniste des processus chimiques et une approche plus traditionnelle, soupçonnée d’emprunter ses thèses à l’alchimie, mais qui sera pourtant à l’origine de la table des affinités qui sera adoptée par tous les chimistes jusqu’au début du XIXe siècle.

In this paper we investigate AGM belief contraction operators by using the tools of algebraic logic. We generalize the notion of contraction to arbitrary finitary propositional logics, and we show how to switch from a syntactic-based approach to a semantic one. This allows to build a solid bridge between the validity of AGM postulates in a propositional logic and specific algebraic properties of its intended algebraic counterpart. Such a connection deserves particular attention when we deal with maxichoice contractions, as studied (...) in the final part of the paper. (shrink)

This chapter deals with the ways in which entrepreneurships driven by industrial design and the strategies for interconnecting design for innovation are articulated. In the first instance, current practices are recognized in order to analyze the different processes that entrepreneurial dynamics go through. This analysis is carried out from a systemic perspective, at three levels of abstraction: designer, entrepreneurship and ecosystem. The theoretical and conceptual framework will be structured based on the innovations driven by design, which occur around the designer, (...) his personal projects, and the possible interactions and singularities offered by living spaces. The objective of this work is to unravel the eventual relationships of the entrepreneurial designer in the ecosystem and to highlight the potential added by emerging connections, which allow for the projection of synergistic actions with other actors to create value(s). In this way, other possible views of the entrepreneurial process are provided, where the cultural and philosophical dimension that characterizes industrial designers allows them to achieve a higher quality of life, designing and producing collectively (in) their environment.

This paper develops the concept of ‘creative attention’. Against classical theories that understand attention as a spotlight that brings objects into focus, I will argue that attention is a complex phenomenon structured in different layers. The most basic layer is perceptual, passive and pre-predicative: at this level, attention is creative – and this is the central claim of this paper – because it institutes meanings and rules for our behaviour.

The paper defends Collingwood's account of rational explanation against two objections. The first is that he psychologizes the concept of practical reason. The second is that he fails to distinguish mere rationalizations from rationalizations that have causal power. I argue that Collingwood endorses a form of nonpsychologizing internalism which rests on the view that the appropriate explanans for actions are neither empirical facts (as externalists claim), nor psychological facts (as some internalists claim), but propositional facts. I then defend this form (...) of internalism against a range of Davidsonian objections which attempt to weaken the distinction between reasons and causes. (shrink)

Three studies investigated implicit brand attitudes and their relation to explicit attitudes, prod- uct usage, and product differentiation. Implicit attitudes were measured using the Implicit As- sociation Test (IAT; Greenwald, McGhee, & Schwartz, 1998). Study 1 showed expected differ- ences in implicit attitudes between users of two leading yogurt brands, also revealing significant correlations between IAT-measured implicit attitudes and explicit attitudes. In Study 2, users of two fast food restaurants (McDonald’s and Milk Bar) showed implicit attitudi- nal preference for their (...) favorite restaurant. In Study 3, implicit attitudes of users of two soft drinks (Coca-Cola and Pepsi) predicted brand preference, product usage, and brand recognition in a blind taste test. A meta-analytic combination of the three studies showed that the use of IAT measures increased the prediction of behavior relative to explicit attitude measures alone. (shrink)
