    The Nemo-3 Experiment and the Supernemo Project

    Full text link
    The NEMO experiment is investigating the neutrinoless double beta decay. The NEMO-3 detector is taking data in the Frejus Underground Laboratory. The goal of the SuperNEMO detector is to reach a sensitivity on the order of 10^26 year on the half-life of the bb0nu process. The chosen isotopes for the future detector are 82Se and 150Nd, because of the reduced background. The collaboration has started a 3-year R&D development on all components : tracking detector, calorimeter, source enrichment and purification, radiopurity measurements.Comment: proceeding of ICHEP 0

    Computing the Two-Sided Kolmogorov-Smirnov Distribution

    We propose an algorithm to compute the cumulative distribution function of the two-sided Kolmogorov-Smirnov test statistic D_n and its complementary distribution in a fast and reliable way. Different approximations are used in different regions of n, x. Java and C programs are available.

    Embedding Web-based Statistical Translation Models in Cross-Language Information Retrieval

    Although more and more language pairs are covered by machine translation services, there are still many pairs that lack translation resources. Cross-language information retrieval (CLIR) is an application which needs translation functionality of a relatively low level of sophistication since current models for information retrieval (IR) are still based on a bag-of-words. The Web provides a vast resource for the automatic construction of parallel corpora which can be used to train statistical translation models automatically. The resulting translation models can be embedded in several ways in a retrieval model. In this paper, we will investigate the problem of automatically mining parallel texts from the Web and different ways of integrating the translation models within the retrieval process. Our experiments on standard test collections for CLIR show that the Web-based translation models can surpass commercial MT systems in CLIR tasks. These results open the perspective of constructing a fully automatic query translation device for CLIR at a very low cost.Comment: 37 page

    Aquaculture and Marine Protected Areas: Exploring Potential Opportunities and Synergies

    Get PDF
    This new publication, aims at exploring potential opportunities and synergies between aquaculture and conservation. Acknowledging that both aquaculture and MPA may benefit from each other in striving for global sustainable development, here are some of the questions the brochure explores: Under what circumstances can MPAs and aquaculture come together? How could MPAs boost aquaculture growth? How could aquaculture activities provide financial support to MPAs? And how can we minimize negative interactions

    Organizational and Individual Determinants of Atypical Employment: The Case of Multiple Jobholding and Self-Employment

    Get PDF
    Traditionally, the company has been attributed relative control over employees' career paths, particularly in the case of very active organizational management. However, the growing need for organizational flexibility has led to the increasing recourse to atypical work, which in turn contributes to consolidating new careers in which the themes of control and autonomy acquire new meaning. Of these forms of atypical work, multiple jobholding and self-employment have particularly intrigued researchers. Using data compiled by Statistics Canada, we have sought to identify, through logistic regression analyses, the factors that influence the probability of belonging to these two categories of atypical employment. Our results suggest that the influence factors are not identical for the non-standard two job categories studied. Sector of activity, sex and the absence of promotion have a considerable impact on the probability of joining the ranks of the self-employed, whereas professional category and frequency of movement significantly influence the probability of belonging to the multiple jobholder group. Our results also show that the makeup of the populations engaging in these two forms of atypical work is not homogeneous, and that belonging to one of these groups does not necessarily entail precarious living and working conditions. Le rôle traditionnel de la gestion de carrière attribuait à l'entreprise un certain contrôle sur le cheminement des individus, dans la mesure où la prise en charge organisationnelle était très active. Toutefois, le besoin incessant de flexibilité organisationnelle, qui mène à l'utilisation croissante du travail atypique, contribue à la consolidation des nouvelles carrières dans lesquelles les thèmes du contrôle et de l'autonomie sont questionnés. Parmi ces formes de travail atypique, le cumul d'emplois et le travail autonome/à son compte ont particulièrement retenu l'attention des chercheurs. En utilisant des données produites par Statistique Canada, nous avons cherché à identifier, par l'entremise des analyses de régression logistique, les facteurs qui influencent la probabilité de faire partie de ces deux catégories d'emploi atypique. Nos résultats suggèrent que les facteurs d'influence ne sont pas les mêmes pour les deux catégories d'emploi non standard considérées. Le secteur d'activité, le sexe et les promotions jouent davantage sur la probabilité de joindre les effectifs des autonomes/à son compte alors que la catégorie professionnelle, la fréquence du mouvement et l'absence de promotion influencent davantage la probabilité d'appartenir au groupe des cumulards. Finalement, nos résultats montrent que les effectifs de ces deux types de travail atypique ne sont pas homogènes et que l'appartenance à l'un ou l'autre de ces groupes n'implique pas exclusivement la précarité des conditions de vie et de travail.Multiple jobholding, self-employment, new career, Travail atypique, cumul d'emplois, travail autonome/à son compte, flexibilité organisationnelle
