    Traditionnellement, le dĂ©veloppement local en rĂ©fĂ©rence aux milieux urbains s’est avant tout dĂ©fini Ă  l’échelle des quartiers. Nous avançons ici l’hypothĂšse que, Ă  la faveur de la mondialisation, les acteurs sociaux qui en ont fait la promotion dans le passĂ©, en particulier les acteurs du milieu communautaire, devraient dorĂ©navant se tourner vers l’espace mĂ©tropolitain, car c’est Ă  cette Ă©chelle que prennent place, de plus en plus, non seulement le dĂ©veloppement Ă©conomique, mais aussi la gestion des problĂšmes sociaux et environnementaux. Pour vĂ©rifier cette hypothĂšse, nous avons fait une Ă©tude empirique des pratiques des organismes communautaires de la rĂ©gion de MontrĂ©al en matiĂšre de dĂ©veloppement local, en accordant une attention particuliĂšre Ă  leur engagement sur le plan de la dĂ©mocratie locale. Toutefois, les rĂ©sultats de notre enquĂȘte n’ont pas permis de vĂ©rifier notre hypothĂšse. Cela peut sans doute ĂȘtre expliquĂ©, du moins en partie, par le fait que l’espace mĂ©tropolitain en tant que territoire politique demeure relativement rĂ©cent Ă  MontrĂ©al.Traditionally, local development in the urban context is defined at the level of neighbourhoods. We hypothesize that, with the influence of globalization, social actors, particularly those in local communities, should be turning towards urban spaces because it is the level not only for economic development, but also for managing social and environmental problems. In order to test our hypothesis, we examined empirically the practices of community organizations in the Montreal region, particularly as regards their approach and plans for local development and their commitment to local democracy. However, the results of this study did not allow us to confirm that hypothesis. That can be explained, at least in part, by the fact that the Montreal region has only recently become defined as a political space

    Initiatives communautaires de développement local et gouvernance métropolitaine : quel emboßtement ?

    La mondialisation des Ă©changes, la restructuration des Ă©conomies urbaines et la reconfiguration de l’État-providence ont conduit Ă  deux types de stratĂ©gies de dĂ©veloppement au sein des mĂ©tropoles nord-amĂ©ricaines : d’une part, celles qui relĂšvent d’initiatives communautaires de dĂ©veloppement local et qui s’attaquent au chĂŽmage et Ă  la pauvreté ; d’autre part, celles qui reposent sur diverses formes de gouvernance mĂ©tropolitaine et qui visent le positionnement de ces mĂ©tropoles sur l’échiquier international. Y a-t-il un arrimage entre ces deux types de stratĂ©gies et les organismes qui les portent ? C’est Ă  cette question que tente de rĂ©pondre le prĂ©sent article en comparant quatre mĂ©tropoles : MontrĂ©al, Toronto, Boston et Pittsburgh

    Sub-ppm (HCl) and (H2O) monitoring using photoacoustic spectroscopy is reported in optical fibre manufacturing for the production of low-water-peak fibres. Contamination sources of the carrier gas used for fibre preforms manufacturing were identified and discussed

    Safety profile of the RTS,S/AS01 malaria vaccine in infants and children: additional data from a phase III randomized controlled trial in sub-Saharan Africa

    A phase III, double-blind, randomized, controlled trial (NCT00866619) in sub-Saharan Africa showed RTS,S/AS01 vaccine efficacy against malaria. We now present in-depth safety results from this study. 8922 children (enrolled at 5-17\xC2\xA0months) and 6537 infants (enrolled at 6-12\xC2\xA0weeks) were 1:1:1-randomized to receive 4 doses of RTS,S/AS01 (R3R) or non-malaria control vaccine (C3C), or 3 RTS,S/AS01 doses plus control (R3C). Aggregate safety data were reviewed by a multi-functional team. Severe malaria with Blantyre Coma Score \xE2\x89\xA42 (cerebral malaria [CM]) and gender-specific mortality were assessed post-hoc. Serious adverse event (SAE) and fatal SAE incidences throughout the study were 24.2%-28.4% and 1.5%-2.5%, respectively across groups; 0.0%-0.3% of participants reported vaccination-related SAEs. The incidence of febrile convulsions in children was higher during the first 2-3 days post-vaccination with RTS,S/AS01 than with control vaccine, consistent with the time window of post-vaccination febrile reactions in this study (mostly the day after vaccination). A statistically significant numerical imbalance was observed for meningitis cases in children (R3R: 11, R3C: 10, C3C: 1) but not in infants. CM cases were more frequent in RTS,S/AS01-vaccinated children (R3R: 19, R3C: 24, C3C: 10) but not in infants. All-cause mortality was higher in RTS,S/AS01-vaccinated versus control girls (2.4% vs 1.3%, all ages) in our setting with low overall mortality. The observed meningitis and CM signals are considered likely chance findings, that - given their severity - warrant further evaluation in phase IV studies and WHO-led pilot implementation programs to establish the RTS,S/AS01 benefit-risk profile in real-life settings

    Energy Resolution Performance of the CMS Electromagnetic Calorimeter

    Get PDF
    The energy resolution performance of the CMS lead tungstate crystal electromagnetic calorimeter is presented. Measurements were made with an electron beam using a fully equipped supermodule of the calorimeter barrel. Results are given both for electrons incident on the centre of crystals and for electrons distributed uniformly over the calorimeter surface. The electron energy is reconstructed in matrices of 3 times 3 or 5 times 5 crystals centred on the crystal containing the maximum energy. Corrections for variations in the shower containment are applied in the case of uniform incidence. The resolution measured is consistent with the design goals

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð„with constraintsð ð ð„ „ ðandðŽð„ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
