Les conditions de succès de l'implantation d'un comité patronal-syndical sur la réorganisation du travail : une comparaison de deux cas dans le secteur de la métallurgie au Québec

Mémoire numérisé par la Direction des bibliothèques de l’Université de Montréal.Cette recherche porte sur l'analyse de deux expériences récentes nées d'ententes collectives instituant une participation syndicale à la réorganisation du travail dans deux établissements du secteur de la métallurgie au Québec. L'une s'avère un succès (Reynolds, Cap-de-la-Madeliene) et l'autre un échec (Québec Fer et Titane, Tracy). Afin de mettre en évidence les facteurs explicatifs du succès ou de l'échec de ces expériences / nous avons recours à un cadre d'analyse prédéterminé basé sur la revue de la littérature pertinente postulant que le succès de la coopération patronale-syndicale est associé a certaines variables. Ainsi, la réussite de l'implantation d'un comité conjoint patronal-syndical sur l'organisation du travail serait fonction de certains éléments clés. Premier élément, l'obtention par le syndicat de garanties préalables à l'effet qu'aucune perte d'emploi ne résultera de l'implantation de mesures découlant des décisions prises par le comité conjoint sur la réorganisation du travail. Deuxième élément, la mise en place de mécanismes formels qui, à long terme, assurent que la voix collective des salariés puisse s'exprimer à l'intérieur du comité conjoint sur la réorganisation du travail. Troisième élément, la tenue de débats au sein du syndicat afin de déterminer la position syndicale sur les modalités de fonctionnement du comité conjoint sur la réorganisation du travail, avant la signature de l/entente portant sur la mise en place de ce comité. Et finalement, l'existence d'un climat de relations patronales-syndicales qui amènerait le seuil minimal de confiance mutuelle nécessaire pour s'engager dans ces expériences. Les deux établissements sous étude, Reynolds Cap-de-la- Madeleine et Québec Fer et Titane de Tracy, présentaient certaines caractéristiques communes permettant de contrôler d'autres variables explicatives que celles présentées dans notre cadre d'analyse. Par exemple, les salariés des deux établissements sont affiliés à la Fédération de la métallurgie de la CSN. De plus, les deux établissements ont une taille comparable et opèrent dans le même secteur d'activité soit celui de la métallurgie. Pour ce qui est de la méthodologie, le choix de procéder par une étude de cas a été facilité par notre participation à une recherche, sous la direction du professeur Reynald Bourque, permettant l'accès à ces deux terrains d/étude. Les résultats de notre étude confirment notre cadre d/analyse quant aux principaux facteurs de succès ou d'échec de l'implantation d'un comité conjoint en milieu syndiqué nordaméricain. Les facteurs explicatifs relevés dans la littérature scientifique sur le sujet sont présents dans le cas de l'usine Reynolds au Cap-de-la-Madeleine, tandis qu'ils sont absents au cours de la période étudiée (1991-1994) dans le cas de l'usine Québec Fer et Titane de Tracy. La mise à jour du cas Québec Fer et Titane à Tracy, où une nouvelle entente sur la participation syndicale à la gestion de l'organisation du travail a été signée en juin 1995, montre que révolution au cours des deux dernières années des facteurs clés identifiés ci-haut a contribué au renouvellement des relations patronales-syndicales et à la conclusion d'un nouvel accord. Nos conclusions comportent donc le cadre analytique élaboré à partir d'une revue de la littérature pertinente sur les facteurs de succès de la coopération patronale-syndicale en milieu syndiqué en Amérique du Nord. Toutefois, nos conclusions ne peuvent être généralisées au-delà du contexte nord américain en raison des spécificités du système nord-américain de relations industrielles en ce qui concerne les régimes de reconnaissance syndicale, de monopole, de représentation syndicale, et de la négociation collective

Cyber Infrastructure Protection: Vol. II

View the Executive SummaryIncreased reliance on the Internet and other networked systems raise the risks of cyber attacks that could harm our nation’s cyber infrastructure. The cyber infrastructure encompasses a number of sectors including: the nation’s mass transit and other transportation systems; banking and financial systems; factories; energy systems and the electric power grid; and telecommunications, which increasingly rely on a complex array of computer networks, including the public Internet. However, many of these systems and networks were not built and designed with security in mind. Therefore, our cyber infrastructure contains many holes, risks, and vulnerabilities that may enable an attacker to cause damage or disrupt cyber infrastructure operations. Threats to cyber infrastructure safety and security come from hackers, terrorists, criminal groups, and sophisticated organized crime groups; even nation-states and foreign intelligence services conduct cyber warfare. Cyber attackers can introduce new viruses, worms, and bots capable of defeating many of our efforts. Costs to the economy from these threats are huge and increasing. Government, business, and academia must therefore work together to understand the threat and develop various modes of fighting cyber attacks, and to establish and enhance a framework to assess the vulnerability of our cyber infrastructure and provide strategic policy directions for the protection of such an infrastructure. This book addresses such questions as: How serious is the cyber threat? What technical and policy-based approaches are best suited to securing telecommunications networks and information systems infrastructure security? What role will government and the private sector play in homeland defense against cyber attacks on critical civilian infrastructure, financial, and logistical systems? What legal impediments exist concerning efforts to defend the nation against cyber attacks, especially in preventive, preemptive, and retaliatory actions?https://press.armywarcollege.edu/monographs/1527/thumbnail.jp

Human Tau Expression Does Not Induce Mouse Retina Neurodegeneration, Suggesting Differential Toxicity of Tau in Brain vs. Retinal Neurons

The implication of the microtubule-associated protein (MAP) Tau in the ocular manifestations of Alzheimer’s disease (AD) is elusive due to the lack of relevant animal model. However, signs of AD have been reported in the brain of transgenic mice expressing human Tau (hTau). To assess whether hTau is sufficient to induce AD pathogenesis in the retina as well, in the present study, we compared the retinal structure and function of KO mice deprived of Tau (mTKO) with those of transgenic mice expressing hTau. Our results revealed that hTau is particularly abundant in the inner nuclear layer (INL) cells of the retina. By electroretinogram (ERG) recording, light-induced retinal cell activation was not altered in hTau compared with mTKO littermates. Surprisingly, the ERG response mediated by cone photoreceptor stimulation was even stronger in hTau than in mTKO retinae. Immunofluorescent analysis of retinal sections allowed us to observe thicker inner retina in hTau than in mTKO eyes. By Western Blotting (WB), the upregulation of mTOR that was found in hTau mice may underlie retinal structure and function increases. Taken together, our results not only indicate that hTau expression is not toxic for retinal cells but they also suggest that it may play a positive role in visual physiology. The use of hTau may be envisaged to improve visual recovery in ocular diseases affecting the retinal function such as glaucoma or diabetic retinopathy

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson
