Modelling of contagious disease usually employs compartmental SEIR-like models where the waiting times in respective compartments are exponentially distributed. In this paper, we are interested in investigating how the distributions of sojourn times in infective compartments affect the dynamics and persistence of the contagious bovine pleuropneumonia, a chronic respiratory disease of cattle. Two kinds of extreme distributions of the sojourn times are considered: a Dirac delta-function and truncated Gaussian function leading to a model with (non-constant) delay and the classical exponential (...) distribution that stands for a model without delay. Expressions of the basic reproductive numbers are derived and dynamical behaviours are discussed for the three models. It is found that the spreading of disease exhibits wave-like oscillations for the time-delay dynamics. In contrast, the disease appears to last longer when the spreading is described by the classical dynamics without delay. Subsequently, the time-delay dynamics turns out to be more appropriate for the description of an experimental epidemic of CBPP. (shrink)
This paper gives a philosophical outline of the initial foundations of politics as presented in the work of Plato and argues why this traditional philosophical approach can no longer serve as the foundation of politics. The argumentation is mainly based on the work of Latour (1993, 1997, 1999a, 2004, 2005, 2007, 2008) and consists of five parts. In the first section I elaborate on the initial categorization of politics and science as represented by Plato in his Republic. In the second (...) section I discuss the gap between humans and non-humans and how they are tied together in actual real life political topics. In the third section I elaborate on the concepts of political and scientific discourse and how they are thought of as separated fields based on the ancient constitution of human society. In the fourth section I link the concepts of matter of fact and matter of concern. In a final section I present a redefinition of the nature of politics as represented in the work of Bruno Latour as an alternative foundation for the study of political systems. (shrink)
In this comment I want to clarify five topics. The first topic concerns the importance of looking back at the very principles of the foundations of Western society. The second comment argues for the original position of Latour within the field of (social) constructivism. In the third comment, I argue that Haraway adds to the science-politics discussion by elaborating her philosophy beyond dichotomy. In the fourth comment, I argue that the terms ‘objective’ and ‘rational’ are central philosophical concepts which should (...) be retained. Finally I will make the connection between ‘what’ is represented and ‘how’ to represent it. (shrink)
It is a rather safe statement to claim that the social dimensions of the scientific process are accepted in a fair share of studies in the philosophy of science. It is a somewhat safe statement to claim that the social dimensions are now seen as an essential element in the understanding of what human cognition is and how it functions. But it would be a rather unsafe statement to claim that the social is fully accepted in the philosophy of mathematics. (...) And we are not quite sure what kind of statement it is to claim that the social dimensions in theories of mathematics education are becoming more prominent, compared to the psychological dimensions. In our contribution we will focus, after a brief presentation of the above claims, on this particular domain to understand the successes and failures of the development of theories of mathematics education that focus on the social and not primarily on the psychological.

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements (...) usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase. (shrink)
A new model of bioturbation has been developed to describe short term sediment reworking induced by macrobenthic communities. The design of the model had to consider the mixing processes, firstly, at the organism level, and secondly, at community level. This paper describes the mixing mode of the four types of bioturbators defined by the authors: the biodiffusors, the upward-conveyors, the downward-conveyors and the regenerators. The mathematical formulation of these sub-models consists of ordinary differential equations. They take into account the size (...) of the bioturbated zone, the output fluxes to the water column, tracer decay, physical mixing due to local currents and the type and intensity of the bioturbation processes. These sub-models make it possible to describe correctly the mixing events that have occurred in cores with each type of bioturbator. They also provide the basis for general bioturbation model, that will take into account the respective degrees of involvement of (i) the different bioturbation processes and their characteristics, (ii) the interference between the different processes, and (iii) make possible to predict the particle reworking in order to include it in studies of organic matter in early diagenesis.

L'acüon educative repose sur un double fondement: d'une part, la nature et la vocation de l'etre humain, et d'autre part, la societe humaine ä bätir. L'homme a des traits specifiques qui exigent et en meme temps permettent son education: il est imparfait, inacheve (il ne sait pas tout, il ne se comporte pas for cement bien), il faut done l'amener ä s'ameliorer; il est perfectible e'est-a-dire qu'il peut devenir meilleur; il a la volonte de se depasser, de tendre vers l'ideal, (...) ideal qu'il n'atteint, bien sür, jamais; il est capable materiellement, intellectuellement (grace ä sa formation, ä son experience) d'agir sur autrui, de le mener vers cet ideal; enfln, il est conscient de devoir le faire, car l'homme ne peut et ne doit etre eduque que par l'homme. Et, second justificatif de Taction educative: la societe des hommes et les rapports devant exister entre eux. L'homme, par essence, Vit et est fait pour vivre en collectivite. Celle-ci doit etre harmonieuse, bien organisee, de preference sous forme d'Etat, pour le bonheur de tous les membres, lesquels doivent etre ä meme de concourir ä l'edification d'une societe egalitaire, toutes choses qui necessitent Taction educative.

Cet article s’interroge la temporalité de la santé : il s’efforce de démontrer que les phénomènes de santé et de maladie peuvent être dits temporels non pas accidentellement, mais essentiellement. Il met au jour quatre aspects temporels de la santé : son épaisseur de durée, sa relation avec l’avenir, la nature partiellement rétrospective des jugements dans lesquels elle entre, et son irréversibilité.
Taking its cue from François Bernier’s Voyages and focusing on the assumptions that stand in the background of Immanuel Kant’s view of the encounter between Christianity and Hinduism, this text endeavors to bring to light the theoretical framework that shaped the dialogue between the West and the East since the 18th century. The author’s contention is that the way that Western philosophy has tended to conceive of universal values has been one of the fundamental obstacles that has hindered a (...) genuine cross-cultural conversation in this sense.

Jean-Francois Lyotard is often considered to be the father of postmodernism. Here leading experts in the field of cultural and philosophical studies, including Barry Smart, John O' Neill and Victor J. Seidler, tackle many of the questions still being asked about this controversial figure.
Philosophers and Buddhist scholars have noted the affinities between David Hume’s empiricism and the Buddhist philosophical tradition. I show that it was possible for Hume to have had contact with Buddhist philosophical views. The link to Buddhism comes through the Jesuit scholars at the Royal College of La Flèche. Charles François Dolu was a Jesuit missionary who lived at the Royal College from 1723–1740, overlapping with Hume’s stay. He had extensive knowledge both of other religions and cultures and of (...) scientific ideas. Dolu had had first-hand experience with Theravada Buddhism as part of the second French embassy to Siam in 1687–1688. In 1727, Dolu also had talked with Ippolito Desideri, a Jesuit missionary who visited Tibet and made an extensive study of Tibetan Buddhism from 1716–1721. It is at least possible that Hume heard about Buddhist ideas through Dolu. (shrink)
There is a long-standing view that Malebranche and his fellow occasionalists accepted occasionalism to solve the problem of interaction between immaterial souls and extended bodies. Recently, however, scholars have shown this story to be a myth. Malebranche, Geulincx, La Forge, and Cordemoy adopted occasionalism for a variety of reasons, but none did so because of a need to provide a solution to a perceived mind-body problem. Yet there is one Cartesian for whom the “traditional” reading is largely on the mark. (...)François Lamy argues in the second volume of his De la Connoissance de Soi-Meme much as the standard story has it. In this article I discuss and analyze Lamy’s argument, showing how he deals with some of the many concerns that made occasionalism attractive, and how he brings out some of the thorny questions that an occasionalist must face.

This is an essay about language, thought, and culture in general, and about Ancient Greek and Classical Chinese in particular. It is about the Sapir-Whorf hypothesis, which says that language influences the mind, and applies this hypothesis to Greek and Chinese. It is also an essay in comparative philosophy as well as a contribution to the history of ideas. From the language side, I rely on the nineteenth-century German linguist Wilhelm von Humboldt, and from the culture side on the contemporary (...) French sinologist François Jullien. Combining their ideas, I give substance to the Sapir-Whorf hypothesis and explain some of Jullien's claims about the historical and political developments of Chinese culture. The central .. (shrink)
Discourse, Figure signifies an event. I mean this in a variety of ways. There has been a recent event: the publication of an English translation of Jean-François Lyotard’s first major book. Its translation is an event forty years delayed and signifies the closing of a major gap in the translation of Lyotard’s work. Of course, both “signify” and “event” are important words for Lyotard. Discourse, Figure’s goal is to “signify the other of signification” (2011, 13, emphasis his). The question (...) of the representability of events that concerns Lyotard throughout his career originates in Discourse, Figure. I use these two words to guide my review. First I outline the events of the book: its context and its argument. .. (shrink)
The existence of a genetic program of development was proposed by molecular biologists in the nineteen-sixties. Historians and philosophers of science have since thoroughly criticized this notion. To fully appreciate its significance, it is interesting to consider the research which was pursued during this period by molecular biologists who proposed this notion. This study focuses on François Jacob's work and on the model of development supported by his lab in the early seventies, the T-complex model. This episode of Jacob's (...) scientific activity has since been forgotten. Characterization of this model shows that the notion of program was used in a metaphoric way and that it did not put any constraint on the work pursued in the lab at that time. Some attention is devoted to the origin of this metaphor in the context of the nineteen-seventies. (shrink)
Fragments presents a set of brilliantly intriguing interviews with Jean Baudrillard whose work today occupies center stage in the analysis of consumerism, terrorism, and contemporary culture. In these frank discussions with François L'Yvonnet, Baudrillard reveals for the first time in detail the thinkers who have been the dominant influences on his work during his career. Instead of examining his work as a project of intellectual accumulation, he challenges all the major interpretations of his work by suggesting he has always (...) adopted an anti-system, anti-totality strategy. Even globalization is accompanied in his view by a Western culture which itself is no longer a well-founded confident universalism. Perhaps most interestingly, Baudrillard discusses his life's work in relationship to his contemporaries -- Bataille , Barthes, Lyotard and Deleuze - and explores his position as an outsider in the field of French philosophy. Baudrillard in these interviews is in sparkling form, and in his ownwords he presents not only a lively introduction to this great thinker but also gives readers a window into a brilliant mind.

Summary The paper follows the lives of Mateu Orfila and François Magendie in early nineteenth-century Paris, focusing on their common interest in poisons. The first part deals with the striking similarities of their early careers: their medical training, their popular private lectures, and their first publications. The next section explores their experimental work on poisons by analyzing their views on physical and vital forces in living organisms and their ideas about the significance of animal experiments in medicine. The last (...) part describes their contrasting research on the absorption of poisons and the divergences in their approaches, methods, aims, standards of proof, and intended audiences. The analysis highlights the connections between nineteenth-century courtrooms and experimental laboratories, and shows how forensic practice not only prompted animal experimentation but also provided a substantial body of information and new research methods for dealing with major theoretical issues like the absorption of poisons.

This paper examines the analysis of property regimes in the thought of the French philosopher, Francois Huet, as presented especially in his one major work on that subject, Le Regne Social du Christianisme (1853). There, Huet developed his concern with social issues which began in the mid-1840s, when he was Professor of Philosophy at the University of Ghent. From 1846, he formed a study group of students now known as the �Huet Society�, which discussed social questions such as property rights (...) and inheritance, and considered various reform proposals in the works of Fourier, Proudhon, Saint-Simon and others. In the aftermath of the 1848 Revolutions, Huet resigned his Chair following an official campaign against his allegedly subversive views. From 1850 until his death in 1869, Huet lived in Paris where he concentrated on his studies, producing a large number of published works. Apart from Le Regne, those works were concerned principally with Catholic theology, at least until 1864 when Huet renounced his faith and sought to develop a version of pantheism. However, in La Science de l'esprit (1864), which immediately preceded that renunciation, Huet restated at length and in virtually identical form the core argument of Le Regne. Even in one of his last works, La Revolution Religieuse (1868), moreover, Huet expressed his continuing endorsement of its �fundamental idea� of �a guarantee of property to all�, and argued that after fifteen years it was still in advance of current liberal critiques of property regimes.

The distinguished philosopher of language, Francois Recanati, has proposed a wide-ranging truth-conditional model of pragmatics. In this collection, various aspects of his theories are addressed by distinguished contributors, and are then commented on or answered by Recanati himself. This allows the reader to be drawn into the central debate within philosophy of language and cognitive science as to what kind of pragmatics system is needed.
Etienne-François Geoffroy, l’un des chimistes français les plus importants du début du XVIIIe siècle, entretenait des relations régulières avec l’Angleterre. Il était chargé de développer les échanges entre l’Académie royale des sciences et la Royal Society de Londres. Quand il publia sa « Table des rapports entre les substances chimiques » en 1718, Fontenelle et quelques autres lui reprochèrent d’avoir introduit en chimie le système des attractions newtoniennes. Mais en fait, Geoffroy s’est toujours tenu à l’écart aussi bien du (...) mécanisme cartésien que du newtonianisme, le recours aux expériences et à la littérature alchimique constituant ses seules sources d’inspiration. Geoffroy apparaît ainsi comme le représentant d’une chimie empirique, soucieuse de conserver l’autonomie de sa discipline. (shrink)

The focus of this paper is the intertextual relationship between the work of François Truffaut and that of Honoré de Balzac. It explores Balzac's influence on the shaping of Truffaut's voice and argues that Balzac's Human Comedy served Truffaut as a model for some of his cinematic innovations. This applies to Truffaut's total oeuvre, but particularly to his series of autobiographical films, ?The Adventures of Antoine Doinel?: The 400 Blows (Les Quatre Cents Coups, 1959), Antoine and Colette, Love at (...) Twenty (Antoine et Colette, L'Amour à Vingt Ans, 1962), Stolen Kisses (Baisers Volés, 1968), Bed and Board (Domicile Conjugal, 1970), Love on the Run (L'Amour en Fuite, 1979). In examining Truffaut's ?rewriting? of Balzac, I adopt?and adapt?the intertextual approach of Harold Bloom's theory of the ?anxiety of influence.? My paper applies Bloom's concept of misreading to an examination of the relationship between Truffaut's autobiographical films, and Balzac's Human Comedy, both thematically and structurally. (shrink)
