This essay stages a critical conversation between Stuart Hall and Ernesto Laclau, comparing their different appropriations of Antonio Gramsci’s theory of hegemony. In the 1980s, Hall and Laclau engaged with Gramsci and with one another in order to conceptualize what they regarded as a triangular relation between the rise of Thatcherism, the crisis of the Left, and the emergence of new social movements. While many of their readers emphasize the undeniable similarities and mutual influences that exist between Hall and Laclau, (...) this essay focuses on the differences between their theories of hegemony and locates the starkest contrast between them at the level of theoretical practice. While the main lesson that Hall drew from Gramsci was the privileging of conjunctural analysis, Laclau proceeded to locate the concept of hegemony at a higher level of abstraction, developing a political ontology increasingly indifferent to any specific conjuncture. The essay argues that this difference between conjunctural analysis and political ontology has a significant impact on Hall’s and Laclau’s respective understandings of two key political formations: populism and identity politics. Thus by focusing on these two formations, the essay argues that Hall’s work should not be read as a derivative or even undertheorized version of Laclau’s, for this tendency obscures substantial differences between their interventions as well as the fact that Hall’s theory of hegemony, as a theory of the conjuncture, ultimately possesses stronger explanatory power than Laclau’s political ontology.

1 Il trapianto di norme e l’apporto della comparazione Così come altre discipline che si fondano sull’interpretazione, anche il diritto è stato interessato, negli ultimi decenni del Novecento, da tentazioni di “debolezza” e di relativismo critico. L’attrazione per le forme più radicali di relativismo ermeneutico pare oggi superata a favore di progetti di ricostruzione del significato degli enunciati giuridici: una nuova sistematica che si legittima nella comparazione esalta la ricerca di “pri...

Proponents of the extended evolutionary synthesis have argued that there are explanatory gaps in evolutionary biology that cannot be bridged by standard evolutionary theory. In this paper, we consider what sort of explanatory gaps they are referring to. We outline three possibilities: data-based gaps, implementation-based gaps, and framework-based gaps. We then examine the purported evolutionary gaps and attempt to classify them using this taxonomy. From there we reconsider the significance of the gaps and what they imply for the proposed need (...) for an extended evolutionary synthesis. (shrink)

Collected works of Maharshi Ramana, Hindu philosopher.

Jean Cavaillès (15 mai 1903-17 février 1944) était un philosophe français, héros et l'un des organisateurs de la Résistance, avant d'être fusillé à 40 ans par les nazis. Une journée d'hommage lui a été consacrée le 17 février 2014 à l'Ecole normale supérieure de Paris. Pierre-Yves Canu, Tommy Murtagh, Hourya Benis Sinaceur, Paul Cortois, Alya Aglan, Baptiste Mélès, Gerhard Heinzmann et Jacques Lautman présentent un Cavaillès indissociablement philosophe et Résistant, explorent les racines de sa pensée, montrent l'actualité de ses (...) concepts. Jean-Jacques Szczeciniarz et Christian Houzel proposent une analyse du Mouvement de la jeunesse allemand, un historique de la société Les Amis de Jean Cavaillès, éditrice du présent recueil, et deux hommages à celui qui la présida de 1989 à 1995, le mathématicien Henri Cartan.

Substrate cycles are ubiquitous structures of the cellular metabolism (e.g. Krebs cycle, fatty acids -oxydation cycles, etc... ). Moiety-conserved cycles (e.g. adenine nucleotides and NADH/NAD, etc...) are also important.The role played by such cycles in the metabolism and its regulation is not clearly understood so far. However, it was shown that these cycles can generate multistationarity (bistability), irreversible transitions, enhancement of sensitivity, temporal oscillations and chaotic motions (Hervagault & Canu, 1987; Hervagault & Cimino, 1989; Reich & Sel'kov, 1981; Ricard (...) & Soulié, 1982). Fig. 1: Scheme of the open binary substrate cycle under study. The substrate S is converted into P with a net rate v2. Substrate P is converted in turn into S with a net rate v3. Step v2 is inhibited by excess of the substrate, S. In addition, the cycle operates under open conditions, that is zero-order input of S at rates \ga0(v1) and first order outputs of S and P at rates \gaS and \gaP(v4), respectively. (shrink)
