This study sought to present the evolutions and new trends of migrant fishing targeting small pelagics in West Africa from fishing to consumption stage.The work involved the characterization of migrant fishers targeting small pelagics in West Africa (country of origin, fishing gear and target species), modalities of access to resources, estimation
Toddlers favor communicatively presented information over statistical reliability in learning about artifacts.
Observed associations between events can be validated by statistical information of reliability or by testament of communicative sources.We tested whether toddlers learn from their own observation of efficiency, assessed by statistical information on reliability of interventions, or from communicatively presented demonstration, when these two poten
New U(1) gauge model of radiative lepton masses with sterile neutrino and dark matter
An anomaly-free U(1) gauge here extension of the standard model (SM) is presented.Only one Higgs doublet with a nonzero vacuum expectation is required as in the SM.New fermions and scalars as well as all SM particles transform nontrivially under this U(1), resulting in a model of three active neutrinos and one pure energy jeans sterile neutrino, al
