Bourdieu's academic work and his political interventions have always proved controversial, with reactions varying from passionate advocacy to savage critique. In the last decade of his career, the French sociologist Pierre Bourdieu became involved in a series of high-profile political interventions, defending the cause of striking students and workers, speaking out in the name of illegal immigrants, the homeless, and the unemployed, challenging the incursion of the market into the field of artistic and intellectual production. This new study presents (...) the first sustained critical analysis of the political implications of Bourdieu's sociology. Through a close reading of the political speeches and pronouncements of his later years, Jeremy F. Lane provides a detailed exposition both of Bourdieu's critique of neo-liberalism and of his own political position. Bourdieu's theory of politics is also brought into critical dialogue with the work of a range of other commentators of a broadly Marxist or post-Marxist orientation who have also intervened in such debates - theorists such as Stuart Hall, Ernesto Laclau and Chantal Mouffe, Judith Butler, Slavoj Zizek and Jacques Rancière. The first sustained analysis of Bourdieu's politics - this study will seek to assess the validity of his claims as to the distinctiveness and superiority of his own field theory as a tool of political analysis. It will be of great use to students, and researchers in sociology, social theory; cultural studies, French studies and political science. (shrink)
We have measured the change of lung mechanical parameters on isolated rabbit lungs exposed to chlorine gas (Cl{in2}). Experimental results show parallel increase in elastance and resistance of impaired lungs. We tried to determine whether this may be explained by a reduction of the ventilated areas in the lung, consecutive to closure of some airways. We have then tried to simulate these experimental results by studying the effects of various airways occlusions imposed on two concurrent models (symmetrical and dissymmetrical) of (...) the tracheo-bronchial tree. For each model, we successively evaluated the resistance of the normal lung, simulated a partial peripheral airways occlusion and estimated the induced changes in total resistance. Analytical expressions of the "occluded lung" elastance and resistance have been found for the symmetrical model but not for the dissymmetrical model (a graphical approach is proposed). With the symmetrical model, simulated results are comparable to experimental ones when the occlusion level is proximal. Whatever the dissymmetry level (δ) of the fractal tree model, we could not simulate the expected increase in resistance with the observed increase in elastance. We conclude that either the occlusion is non homogeneous or the lung impairment is not only a reduction in ventilated areas. (shrink)
There are presently three broad approaches the project of naturalizing intentionality: a purely informational approach (Dretske and Fodor), a purely teleological approach (Millikan and Papineau), and a mixed informationally-based teleological approach (Dretske again). I will argue that the last teleosemantic theory offers the most promising approach. I also think, however, that the most explicit version of a pure teleosemantic theory of content, namely Millikan’s admirable theory, faces a pair of objections. My goal in this paper is to spell out Millikan’s (...) pure teleosemantic theory; then to present two objections; and finally to ask the question whether a teleosemantic framework can be saved from the objections.

The essays collected in this issue all stem from talks delivered at the International Conference, Aesthetic preferences, language games and forms of life: from Ludwig Wittgenstein, which was held on 23-25 January 2013 in the Aula Magna of the Faculty of Education at the University of Florence. Contributions are here published in the same order they were presented at the Conference. With fruitful variety of approach, the entire thematic spectrum of the relationship between Wittgenstein and aesthetics is covered: 1) the (...) question of the presence of specific aesthetic issues in Wittgenstein’s works: from aesthetic judgment to the concept of the beautiful (J.-P. Cometti, G. Tomasi, G. Matteucci); 2) the question of the aesthetic paradigm as the key to understanding Wittgenstein’s philosophical research as a whole as well as the philosopher’s unmistakable style (F. Desideri, S. Säätelä, S. Borutti, F. Valagussa); 3) the issue concerning the crucial difference between showing and saying and the thin boundaries between sense and nonsense (V. Sanfélix, L. Distaso, M. De Iaco); 4) the peculiar, but extremely relevant, question concerning the relationship between music and language (J. Schulte, A. Arbo); 5) the question of the expressive character of the work of art and of the linguistic nature of poetry, considered as a vantage point for the pursuit of the analysis of linguistic facts, as well as the issue of the literary form of Wittgenstein’s later philosophy, with its deeply romantic character (M.W. Rowe, G. Di Giacomo); 6) the controversial issue of "seeing-as" and of its role within theories of depiction and pictoriality (K. Stock, A. Voltolini, E. Caldarola, E. Terrone). (shrink)
This bibliographical review of the modelling of the mitotic apparatus covers a period of one hundred and twenty years, from the discovery of the bipolar mitotic spindle up to the present day. Without attempting to be fully comprehensive, it will describe the evolution of the main ideas that have left their mark on a century of experimental and theoretical research. Fol and Bütschli's first writings date back to 1873, at a time when Schleiden and Schwann's cell theory was rapidly gaining (...) ground throughout Germany. Both mitosis and chromosomes were to be discovered within the space of thirty years, along with the two key events in the animal and plant reproductive cycle, namely fecondation and meiosis. The mitotic pole, a term still in use to this day, was employed to describe a morphological fact which was noted as early as 1876, namely that the lines and the dots of the karyokinetic figure, with its spindle and asters, looks remarkably like the lines of force around a bar magnet. This was to lead to models designed to explain the movements of chromosomes which take place when the cell nucleus appears to cease to exist as an organelle during mitosis. The nature of those mechanisms and the origin of the forces behind the chromosomes' ordered movements were central to the debate. Auguste Prenant, in a remarkable bibliographical synthesis published in 1910, summed up the opposing viewpoints of the vitalists, on the one hand, who favoured the theory of contractility or extensility in spindle fibres, and of those who believed in models based on physical phenomena, on the other. The latter subdivided into two groups: some, like Bütschli, Rhumbler or Leduc, referred to diffusion, osmosis and superficial tension, whilst the others, led by Gallardo and Hartog, focussed on the laws of electromagnetism. Lillie, Kuwada and Darlington followed up this line of research. The mid-20th century was a major turning point. Most of the modelling mentioned above was criticized and fell into disuse after disappearing from research publications and textbooks.This marked the onset of a new era, as electron microscopes made possible the materialization and detailed study of the macromolecular elements of the fibres, filaments and microtubules of the cytoskeleton. The successive phases of (a) de Harven and Bernhard's 1956 discovery of the centriole's ultrastructure, (b) its identification with the basal body of the cilia and flagella, confirming the theory set out by Henneguy and von Lenhossek (1898–99), (c) the universal presence of microtubules in animal, vegetal and eukaryotic protist cells, (d) the polymerization-depolymerization induced reversible transformations of the tubulin pool in mitosing cells (Inoue, 1960), (e) ultrastructural comparative studies of the mitotic apparatus of eukaryotes illustrating the Pickett-Heaps integrating concept of the MTOC (microtubule-organizing centre), (f) the possibility ofin vitro experiments on mtocs or on microtubules, brings us upon the present day, which has seen the focus placed on the concept of motor-proteins (kinesin, dynein) and on cell cycle models. The latter are based on a close coincidence between the observable modifications of the mitotic apparatus and the periodic variations in intracellular concentrations of calcium or of certain enzymes (cyclins, Cdc2) during the main transitions of the cell cycle.
