Utopia

Na história das ideias, os utopistas ocupam um lugar particular : o seu problema não era o de teorizar sobre a sociedade na qual viviam até para melhor a compreender para melhor a transformar, mas de mostrarem os seus defeitos, as taras e as contradições contrapondo-lhe uma organização económica e social imaginária na qual uns e outros estavam abolidos. Imaginar uma “ sociedade ideal » era para eles fazer a demonstração que ela era possível, e era possível aceder-lhe por menos que sejam respe..

Debate on work analysis for prevention / Débat sur l’analyse du travail pour la prévention / Dibattito sull’analisi del lavoro per la prevenzione

The Interdisciplinary Research Program “Organization and Well-Being” is aimed at identifying the relationships between the choices that structure the work processes, and the people’s health, defined in terms of physical, mental and social well-being. A method allowing to connect the analysis of organizational choices and the biomedical analysis of their consequences on the involved subjects has been the object of studies and discussions for three decades. This debate includes comments expressed from points of view concerning: ergonomics, work psychodynamics, work sociology, work psychology, ergology, linguistic activity. The way to conceive organization, action research, inter-disciplinarity and multi-disciplinarity, in the various approaches here represented, are the main object of discussion

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

L'internationalisation de l'économie et la crise du syndicalisme

Renato Di Ruzza, The Internationalization of Capitalism and the Crisis of Trade-Union Movements The effects of the internationalization of the capitalist economy on the crisis and future of union movements is evident in two areas : the competition between workers, on the one hand, and within an ideological-political space, on the other hand. The new configuration of the world economy, which is still taking shape, does not allow for trade-unionism on a national level and does not encourage its establishment on any other level.Di Ruzza Renato.
