The paper describes the conceptual models used to understand the processes determining plant growth rates in response to environmental changes. A series of experiments and growth models were used at three organizational levels: the specific plant organs, the whole plant and the plant canopy. The energy conversion efficiency and the total plant carbon balance were first examined. The carbon partitioning amongst the plant parts was then studied. The energy conversion efficiency is generally understood. In modelling carbon partitioning it was first (...) necessary to establish the carbon demand for each plant organ. The carbon partitioned amongst plant organs was then calculated in two ways. The first one based on empirical data consisted in defining which organ received the carbon prior to other organs. The second one was based on the relationship between the carbon mass of specific organs and their trophic activity. This hypothesis allowed the optimization of the carbon partitioning in order to maximize the whole plant growth rate. The opportunities to use these theoretical approaches in plant growth modelling are discussed. (shrink)

Jean-François Lyotard (1924-1998) was one of the most important French philosophers of the Twentieth Century. His impact has been felt across many disciplines: sociology; cultural studies; art theory and politics. This volume presents a diverse selection of interviews, conversations and debates which relate to the five decades of his working life, both as a political militant, experimental philosopher and teacher. Including hard-to-find interviews and previously untranslated material, this is the first time that interviews with Lyotard have been presented (...) as a collection. Key concepts from Lyotard's thought – the differend, the postmodern, the immaterial – are debated and discussed across different time periods, prompted by specific contexts and provocations. In addition there are debates with other thinkers, including Emmanuel Levinas and Jacques Derrida, which may be less familiar to an Anglophone audience. These debates and interviews help to contextualise Lyotard, highlighting the importance of Marx, Freud, Kant and Wittgenstein, in addition to the Jewish thought which accompanies the questions of silence, justice and presence that pervades Lyotard's thinking.

The political writings of Jean-Francois Lyotard, the prophet of the postmodern, are presented here as both the missing dimension of his work and the key to understanding his position within contemporary debate.

"In a wide-ranging discussion the author examines the philosophy of Kant, Heidegger, Adorno and Derrida and looks at the works of modernist and postmodernist artists such as Cezanne, Debussy and Boulez. Lyotard addresses issues such as time and memory, the sublime and the avant-garde, and the relationship between aesthetics and politics. Throughout his discussion he considers the close but problematic links between modernity, progress and humanity, and the transition to postmodernity. Lyotard claims that it is the task of literature, philosophy (...) and the arts to bear witness to and explain this difficult transition." "This important contribution to aesthetic and philosophical debates will be of great interest to students in philosophy, literary and cultural theory and politics."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The ambition and proposal for data modeling of myths presented in this paper is to link contemporary technical affordances to some canonical projects developed in structural anthropology. To articulate the theoretical promise and innovation of this proposal, we present a discrete-event system specification modeling and simulation approach in order to perform a generative analysis and a dynamic visualization of selected narratives, aimed at validating and revitalizing the transformational and morphodynamic theory and methodology proposed by Claude Lévi-Strauss in his structural analysis (...) of myth. After an analysis of Lévi-Strauss’s transformational methodology, we describe in detail how discrete-event system specification models are implemented and developed in the framework of a DEVSimPy software environment. The validation of the method involves a discrete-event system specification simulation based on the extension of discrete-event system specification models dedicated to provide a dynamic Google Earth visualization of the selected myth. Future work around the discrete-event system specification formalism in anthropology is described as well as future applications regarding the impact of computational models to new contemporary anthropological domains.

In this paper, we consider how the four key team emergent states for team learning identified by Bell, Kozlowski and Blawath (2012), namely psychological safety, goal orientation, cohesion, and efficacy, operate as a system that produces the team’s learning climate (TLC). Using the language of systems dynamics, we conceptualize TLC as a stock that rises and falls as a joint function of the psychological safety, goal orientation, cohesion, and efficacy that exists in the team. The systems approach highlights aspects of (...) TLC management that are traditionally overlooked, such as the simultaneous influence of and feedback between the four team emergent states and the inertia that TLC can have as a result. The management of TLC becomes an issue of controlling the system rather than each state as an independent force, especially because changing one part of the system will also affect other parts in sometimes unintended and undesirable ways. Thus the value is to offer a systems view on the leadership function of team monitoring with regards to team emergent states, which we term team state monitoring. This view offers promising avenues for future research as well as practical wisdom. It can help leaders remember that TLC represents an equilibrium that needs balance, in addition to pointing to the various ways in which they can influence such equilibrium. (shrink)

Kant describes a conflict among the different theories of knowledge. A productive conflict whose emergence is the origin of a renewal: it awakens the spirit and it leads it to think critically. Philosophy becomes critique, Kant says, when it is not focused on the doctrines and on their demands, but on the relationship between general rules (the “sense”) that coordinates all the faculties – and their particular expression, that is to say the specific cases. Similarly operates the judge, that, in (...) court, has to invent (ausdenken) the rule capable of corresponding to the single case: a judge that, in order to decide (jus dicere) and utter the decision, tries to compensate the absence of adequate legal rules and often decides without the adapt general rule. The problem of the différend does not concern, thus, anthropology. It concerns language. Exemplary cases provide analoga of the sensitive data and are devices that allow the dialectic between different systems of value by connecting their core meaning, the proper names involved and what Kant defines the Darstellung. Nevertheless, against this background, a change of paradigm becomes necessary – a change that entails the break with hegelian philosophy of law and with a thought built on mediation, that is to say with the kantian Zusammenstimmung. It is not possible, nor desirable, to substitute the battle field with the court and to subordinate the individual interests to the general logic of argumentation, because the synthesis of the different voices might imply totalitarianism and the end of the différend might correspond to the beginning of terror.

Most instantiations of the inference ‘y; so if x, y’ seem intuitively odd, a phenomenon known as one of the paradoxes of the material conditional. A common explanation of the oddity, endorsed by Mental Model theory, is based on the intuition that the conclusion of the inference throws away semantic information. We build on this explanation to identify two joint conditions under which the inference becomes acceptable: (a) the truth of x has bearings on the relevance of asserting y; and (...) (b) the speaker can reasonably be expected not to be in a position to assume that x is false. We show that this dual pragmatic criterion makes accurate predictions, and contrast it with the criterion defined by the mental model theory of conditionals, which we show to be inadequate. (shrink)

The psychology of reasoning is increasingly considering agents' values and preferences, achieving greater integration with judgment and decision making, social cognition, and moral reasoning. Some of this research investigates utility conditionals, ‘‘if p then q’’ statements where the realization of p or q or both is valued by some agents. Various approaches to utility conditionals share the assumption that reasoners make inferences from utility conditionals based on the comparison between the utility of p and the expected utility of q. This (...) article introduces a new parameter in this analysis, the underlying causal structure of the conditional. Four experiments showed that causal structure moderated utility-informed conditional reasoning. These inferences were strongly invited when the underlying structure of the conditional was causal, and significantly less so when the underlying structure of the conditional was diagnostic. This asymmetry was only observed for conditionals in which the utility of q was clear, and disappeared when the utility of q was unclear. Thus, an adequate account of utility-informed inferences conditional reasoning requires three components: utility, probability, and causal structure. (shrink)

Combinant des méthodes employées en ethnoscience et en sociolinguistique, cet article formule une hypothèse destinée à expliquer pourquoi, dans certains types de situations, les membres de la société apache occidentale s’abstiennent de parler. En dépit de l’extrême insuffisance des données interculturelles sur le silence, certaines preuves recueillies suggèrent que cette hypothèse peut également s’appliquer à d’autres sociétés.

Henry’s concept of transcendence is highly paradoxical. Most often it seems as though he had simply borrowed Husserl’s classical description of intentionality, as the act of aiming‐at‐something as an independent object, at something given or posited by consciousness outside itself, in the status of a worldly outwardness. This determination of transcendence belongs to Henry’s usual critique of what he calls the ‘ontological monism’ of classical metaphysics and ‘historical phenomenology’. Nevertheless, when Henry endeavours to define the ontological difference between life itself (...) and the living incarnate ego within the sphere of radically subjective immanence, particularly in his last works on truth and on Christianity, he cannot but refer to another concept of transcendence, the theological and metaphysical one. This is a transcendence which claims absolute ontological exteriority, as the being‐in‐itself of the ‘substance’, altogether free of any intentional dependence on the transcendental activity of consciousness. And he uses this last concept to assert, of course, that divine transcendence, as true to the Absolute, is none other than the most radical and deep immanence: the immanence of life itself. (shrink)

In The Differend, Lyotard subjects to scrutiny- from the particular perspective of his notion of 'differend' - the turn of all Western philosophies toward language; the decline of metaphysics; the present intellectual retreat of Marxism; the hopes raised and mostly dashed, by theory; and the growing political despair. Taking his point of departure in an analysis of what Auschwitz meant philosophically, Lyotard attempts to sketch out modes of thought for our present.

There is a sort of natural closeness between Sartre and violence. Many have claimed that Sartre was fascinated by violence. Authors as diverse as Michel-Antoine Burnier and Mohamed Harbi have criticised the violence in Sartre, and even Bernard-Henri Lévy sees in Sartre's preface to Fanon's Les Damnés de la Terre a 'Sartre possédé'. Unlike these authors, we claim that Sartre was in no way fascinated by violence. In his eyes, violence was an historical fact that was characteristic of his time (...) and which he, personally, discovered at an early age. What is more, Sartre's violence is situational. If he discovered the world in books, it was also in books that he discovered violence. Books and history were the melting pots of a violence that haunts Sartre's work. The historical situations in which he found himself explain the omnipresence of violence in his work. (shrink)

" Le nihilisme est devant la porte : d'où nous vient ce plus inquiétant de tous les hôtes? ", demande Nietzsche dans un fragment posthume. L'hôte est ici celui qui vient chez nous et non celui qui octroie l'hospitalité. Le nihilisme est donc cette figure étrange qui vient nous saisir dans notre maison et faire de nous, en dépit de notre résistance, des nihilistes. Mais alors, si " la catastrophe nihiliste " dont parle Nietzsche s'abat sur nous et nous pétrifie (...) sur notre propre seuil, comment devons-nous entendre la dénonciation nietzschéenne du nihilisme et sa tentative héroïque de le surmonter? Les auteurs réunis dans ce volume tentent d'éclairer le sens de la direction à prendre en ces temps obscurs où, toujours selon Nietzsche, nous ne savons plus où aller, où venir parce que nous avons perdu le sens de la terre. Le nihilisme est peut-être la seule lumière qui permet d'éclairer le caractère équivoque du monde moderne. Mais c'est une lumière noire.

Si les interprétations de ce qu'il est convenu de nommer la « dernière philosophie » de Heidegger sont aujourd'hui monnaie courante, non sans risque d'inflation parfois quand on les lie sans précaution à l'engagement politique de l'auteur de Sein und Zeit, personne pourtant n'avait jusqu'ici pris le risque d'aborder la question controversée du « tournant » de front. Les différences évidentes entre un Heidegger I, parti de la phénoménologie pour revenir à une « ontologie fondamentale », et relevant encore à (...) ce titre de la philosophie, et un Heidegger II, voué désormais à une « autre pensée » réfractaire à l'élaboration conceptuelle, sinon à une sorte de mysticisme poétique, paraissent si tranchées à la plupart des commentateurs qu'ils entérinent sans plus attendre une telle division. Celle-ci a d'ailleurs été accréditée par l'auteur lui-même qui, le premier, mentionna l'existence d'un « tournant » de sa propre pensée, en termes réservés toutefois, sinon énigmatiques. (shrink)

The suppression of the Modus Ponens inference is described as a loss of confidence in the conclusion C of an argument ''If A1 then C; If A2 then C; A1'' where A2 is a requirement for C to happen. It is hypothesised that this loss of confidence is due to the derivation of the conversational implicature ''there is a chance that A2 might not be satisfied'', and that different syntactic introductions of the requirement A2 (e.g., ''If C then A2'') will (...) lead to various frequencies in the derivation of this implicature, according to previous studies in the field of causal explanation. An experiment is conducted, whose results support those claims. Results are discussed in the light of the Mental Logic and Mental Model theories, as well as in the light of the pragmatic approach to uncertain reasoning. (shrink)

Foucault débute le cours de 1983, l’avant-dernier de son enseignement au Collège de France, par la lecture de Qu’est-ce que les Lumières?, texte auquel il confère le statut que Kant attribue à l’ Aufklärung, celui de Wahlspruch, à la fois blason, précepte et marque distinctive. On se demande comment le lecteur est engagé par la lecture qu’il expose aux auditeurs du cours. S’agit-il de se reconnaître l’obligé de ce que Kant envisage en termes de sortie, une redistribution du rapport du (...) gouvernement de soi et du gouvernement des autres? S’agit-il de s’approprier d’une manière inédite le mode kantien de l’attention à ce rapport en s’appliquant à un examen théorico-pratique qui sera à la hauteur de ce que l’actualité exige de nous?

È mettendo in primo piano l’idea di filosofia pratica universale, già presente nella filosofia dell’Aufklärung, che Fichte è riuscito a dare un nuovo volto alla speculazione trascendentale postkantiana. Il saggio tenta innanzitutto di ricostruire la filosofia pratica abbozzata negli anni 1793-1794. Viene proposto un breve confronto con Wolf. In seguito, lo studio rivolge la sua attenzione ad uno dei contributi della filosofia pratica universale fichtiana: aver trattato il sentimento come nozione pratica fondamentale, presente nella conoscenza e nell’azione. Infine, si tratta (...) di mostrare che Fichte propose, nella prima Dottrina della Scienza, di fare della filosofia pratica universale una philosophia prima che fosse chiamata a prendere il posto della ontologia dogmatica e della dottrina degli elementi critica. Un confronto con Descartes, Wolff, Kant e Reinhold pone in risalto l’innovazione di Fichte. (shrink)

Analyse des fondements du personnalisme d'E. Mounier, liant la personne et la communauté, d'inspiration augustinienne. L'auteur étudie comment E. Mounier, refusant tout projet de philosophie chrétienne, parvient à articuler une matrice philosophique issue des pensées de Pascal, Descartes et Bergson à l'apport théologique de l'abbé Guerry.

Invoking Laozi and Mencius, Jullien offers an oblique take on efficacy, one of China’s most intriguing yet most influential notions formulated in Daoism, the practice of art, and military strategies. It circumvents the heavy philosophical apparatus of means versus ends and theory versus practice that jam the Western conception of efficacy.
