What the eye does not see : a critical interpretive synthesis of European Union policies addressing sexual violence in vulnerable migrants

AbstractIn Europe, refugees, asylum seekers and undocumented migrants are more vulnerable to sexual victimisation than European citizens. They face more challenges when seeking care. This literature review examines how legal and policy frameworks at national, European and international levels condition the prevention of and response to sexual violence affecting these vulnerable migrant communities living in the European Union (EU). Applying the Critical Interpretive Synthesis method, we reviewed 187 legal and policy documents and 80 peer-reviewed articles on migrant sexual health for elements on sexual violence and further analysed the 37 legal and 12 peer-reviewed articles among them that specifically focused on sexual violence in vulnerable migrants in the EU-27 States. Legal and policy documents dealing with sexual violence, particularly but not exclusively in vulnerable migrants, apply ‘tunnel vision’. They ignore: a) frequently occurring types of sexual violence, b) victimisation rates across genders and c) specific risk factors within the EU such as migrants’ legal status, gender orientation and living conditions. The current EU policy-making paradigm relegates sexual violence in vulnerable migrants as an ‘outsider’ and ‘female only’ issue while EU migration and asylum policies reinforce its invisibility. Effective response must be guided by participatory rights- and evidence-based policies and a public health approach, acknowledging the occurrence and multiplicity of sexual victimisation of vulnerable migrants of all genders within EU borders

Dissolved iron distribution in the tropical and sub tropical south eastern Pacific

International audienceDissolved iron (DFe) distributions (Fe:P (PO43-) we show that DFe was in deficit compared to PO43- resulting from the remineralisation of organic matter. This suggests that the Marquesas islands and the surrounding plateau are not a significant source of DFe. In the gyre, DFe concentrations in the upper 350 m water column were around 0.1 nM and the ferricline was located well below the nitracline. These low concentrations reflect the low input of DFe from the atmosphere, from the ventilation of the upper thermocline with water containing low DFe, and from the low biological activity within in this ultra oligotrophic gyre

The large-scale disk fraction of brown dwarfs in the Taurus cloud as measured with Spitzer

Aims. The brown dwarf (BD) formation process has not yet been completely understood. To shed more light on the differences and similarities between star and BD formation processes, we study and compare the disk fraction among both kinds of objects over a large angular region in the Taurus cloud. In addition, we examine the spatial distribution of stars and BD relative to the underlying molecular gas Methods. In this paper, we present new and updated photometry data from the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope on 43 BDs in the Taurus cloud, and recalculate of the BD disk fraction in this region. We also useed recently available CO mm data to study the spatial distribution of stars and BDs relative to the cloud's molecular gas. Results. We find that the disk fraction among BDs in the Taurus cloud is 41 \pm 12%, a value statistically consistent with the one among TTS (58 \pm 9%). We find that BDs in transition from a state where they have a disk to a diskless state are rare, and we study one isolated example of a transitional disk with an inner radius of \approx 0.1 AU (CFHT BD Tau 12, found via its relatively small mid-IR excess compared to most members of Taurus that have disks. We find that BDs are statistically found in regions of similar molecular gas surface density to those associated with stars. Furthermore, we find that the gas column density distribution is almost identical for stellar and substellar objects with and without disks.Comment: 8 page, 6 figures, Accepted in Astronomy & Astrophysics

Disentangling the Environment of the FU Orionis Candidate HBC 722 with Herschel

We analyze the submillimeter emission surrounding the new FU Orionis-type object, HBC 722. We present the first epoch of observations of the active environs of HBC 722, with imaging and spectroscopy from PACS, SPIRE, and HIFI aboard the Herschel Space Observatory, as well as CO J= 2-1 and 350 um imaging (SHARC-II) with the Caltech Submillimeter Observatory. The primary source of submillimeter continuum emission in the region -- 2MASS 20581767+4353310 -- is located 16\arcsec south-southeast of the optical flaring source while the optical and near-IR emission is dominated by HBC 722. A bipolar outflow extends over HBC 722; the most likely driver is the submillimeter source. We detect warm (100 K) and hot (246 K) CO emission in the surrounding region, evidence of outflow-driven heating in the vicinity. The region around HBC 722 itself shows little evidence of heating driven by the new outbursting source itself.Comment: Accepted by ApJL 10 March 2011; 14 pages, 4 figures, 1 tabl

Impact of oceanic floods on particulate metal inputs to coastal and deep-sea environments: A case study in the NW Mediterranean Sea

An exceptional flood event, accompanying a marine storm, was investigated simultaneously at the entrance and the exit of the Gulf of Lion's hydrosystem (NW Mediterranean) in December 2003. Cs, Cr, Co, Ni, Cu, Zn, Cd and Pb signatures of both riverine and shelf-exported particles indicate that continental inputs and resuspended prodeltaic sediments were intensively mixed with resuspended sediments from middle/outer shelf areas during advective transport. As a result, particles leaving the Gulf of Lion inherited the mean signature of shelf bottom sediments, exporting anthropogenic Pb and Zn out into the open sea. When assessing the particulate metal budget in relation with the event, it appears that the output fluxes accounted for between 15% and 60% of the input fluxes, depending on the element and the period of reference. This trend is also observed for annual budgets, which were drawn up by compiling the data from this study and the literature. Results evidenced that, except some element fluxes during extreme output scenario, outputs never counter-balance the inputs. In its current functioning, the Gulf of Lion's shelf seems to act as a retention/sink zone for particulate metals. Regarding anthropogenic fluxes, the contribution of the oceanic flood of December 2003 to the mean annual scenario is considerable. Environmental impacts onto coastal and deep-sea ecosystems should therefore tightly depend on both the intensity and the frequency of event-dominated sediment transport

Gold-catalyzed synthesis of enantioenriched furfurylamines from amino acids

International audienceA convenient gold-catalyzed asymmetric synthesis of polysubstituted furfurylamines starting from amino acids has been achieved. The cyclization proceeded under mild conditions and generally provided the furan or iodofuran derivatives in good to excellent yields and with high enantiomeric excess. Iodofurans were validated as good intermediates for classical organometallic coupling reactions
