    Ce rapport prĂ©sente les rĂ©sultats d’une recension des Ă©crits permettant d’identifier les Ă©lĂ©ments facilitateurs et les obstacles auxquels les femmes et adolescentes immigrantes et de minoritĂ©s racisĂ©es (FAIMR) sont confrontĂ©es lorsqu’elles cherchent de l’aide en cas de violence entre partenaires intimes (VPI). En nous fondant sur cette recension des Ă©crits, nous prĂ©sentons Ă©galement des recommandations sur la maniĂšre de s’attaquer Ă  ces nombreux obstacles systĂ©miques. Nous traitons notamment de la façon dont les services adressĂ©s aux FAIMR pourraient amĂ©liorer leurs politiques et leurs pratiques, dans le but de mieux les soutenir et de mieux rĂ©pondre Ă  leurs besoins uniques, particuliĂšrement en matiĂšre de VPI. Ce premier rapport, prĂ©parĂ© par l’équipe de recherche sous la coordination de Tatiana Sanhueza, s’inscrit dans le cadre d’un projet plus vaste : Vers des changements systĂ©miques pour Ă©liminer la violence subie par les adolescentes et femmes immigrantes, financĂ© par le ministĂšre Femmes et ÉgalitĂ© des genres Canada, dont la Table de quartier de MontrĂ©al-Nord est l’organisme fiduciaire. Le prĂ©sent rapport est composĂ© comme suit. En premier lieu, nous prĂ©sentons une mise en contexte de l’étude donnant lieu Ă  la problĂ©matique gĂ©nĂ©rale de la VPI et le contexte particulier de MontrĂ©al-Nord. Dans un deuxiĂšme temps, nous exposerons les objectifs de la recherche et la mĂ©thodologie utilisĂ©e. Ensuite, le cadre thĂ©orique qui a guidĂ© l’analyse sera exposĂ©. Dans une quatriĂšme partie, les rĂ©sultats de la recension des Ă©crits seront prĂ©sentĂ©s selon l’approche Ă©cologique, ce qui veut dire organisĂ©s en quatre niveaux : le macrosystĂšme, l’exosystĂšme, le microsystĂšme et l’ontosystĂšme. Dans une cinquiĂšme partie, nous discuterons des facteurs entravant et facilitant la demande d’aide des FAIMR, pour continuer avec des recommandations tirĂ©es de cette recension. Ce rapport termine par quelques conclusions

    Altimetry for the future: Building on 25 years of progress

    Get PDF
    In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the ‘‘Green” Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments’ development and satellite missions’ evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion

    The potential of cork from Quercus suber L. grown in Algeria as a source of bioactive lipophilic and phenolic compounds

    No full text
    This study aimed to assess the lipophilic and phenolic extractives composition of cork of Quercus suber L. grown in Algeria by gas chromatography-mass spectrometry (GC-MS) and ultra-high-performance liquid chromatograhy-mass spectrometry (UHPLC-MS), respectively. The phenolic cork oak extract was also evaluated for its scavenging activity towards DPPH radical, ABTS radical scavenging, reducing power and antibacterial activity against Staphylococcus aureus ATCC, Listeria innocua, Escherichia coil and Pseudomonas aeruginosa. The lipophilic fraction is mainly composed of thirty three compounds, with cerine, friedeline and betulinic acid as the major components. Furthermore, eighteen phenolic compouds were detected in the phenolic extract, with protocatechuic, ellagic and gallic acids as the major compounds. The methanol:water cork extract showed high DPPH scavenging ability with an ICso value of 5.69 mu g mL(-1) and an ABTS enhanced scavenging capacity when compared to BHT and trolox. A reducing power higher than BHA was also found. In addition, the phenolic fraction of cork was shown to inhibit the growth of Staphelococcus aureus (12.1 mm) and Pseudomonas aeroginisa (10.07 mm). These results indicate that algerian cork oak constitutes a good source of natutal bioactive compounds. Morever, this study is a relevant contribution to the valorization of algerian cork industrial residues, for which novel applications could be considered, namely the use of these extracts in food or nutraceutical industry.

    Retama sphaerocarpa: An unexploited and rich source of alkaloids, unsaturated fatty acids and other valuable phytochemicals

    No full text
    The chemical composition of the lipophilic extracts of the stems and grains of the shrub Retama sphaerocarpa was investigated by gas chromatography-mass spectrometry for the first time. Fatty acids is the major family of compounds in both morphological parts, representing between 37.1 and 85.1% of the total compounds detected, followed by sterols in stems and monoglycerides in grains. Considerable amounts of the alkaloids retamine (9.6 g kg(-1). of dry material) and cytisine (0.6 g kg(-1) of dry material) were also found in stems and grains, respectively. Before alkaline hydrolysis octadec-9-enoic (0.7-2.4 g kg(-1) of dry material), octadeca-9,12-dienoic (1.5-2.9 g kg(-1) of dry material) and hexadecanoic (1.1-2.0 g kg(-1) of dry material) acids are the most abundant lipophilic components in both morphological parts. After alkaline hydrolysis the contents of octade-9-enoic, octadeca-9,12-dienoic and octadeca-9,12,15-trienoic acids detected increased considerably ranging from 1.9 to 22.4, 3.6 to 40.1 and 0 to 8.6 g kg(-1) of dry material, respectively. Smaller amounts of long-chain aliphatic alcohols, alpha-tocopherol and beta-amyrin were also found. These data indicates that R. sphaerocarpa stems and grains are a potential source of valuable phytochemicals, with recognized nutritional and phytopharmaceutical applications. (C) 2015 Elsevier B.V.
