Using L1 and L2 Effectively in the Foreign Language Classroom

Drawing on research and the author\u27s experience, this paper presents descriptions and prescriptions regarding the controversial issue of use of L1 (first language) and of L2 (target language) in the foreign language classroom. In the context of her own practice, the author discusses and evaluates techniques and principles that include the use of the use of L1 as well as those that exclude it. This project will examine various interactions among the teacher, the learner, and the content as they relate to LllL2 use in the classroom. Awareness of the variables involved is the foundation for the teacher’s continual adjustment of her own L1IL2 use and of her expectations of learners\u27 use of and L2

Mollusques et faune benthique du lagon de Takapoto

Mollusques et faune benthique du lagon de Takapoto. At least 93 species of Molluscs (58 Gastropods, 34 Bivalves, 1 Cephalopod) exist within the closed lagoon of the Takapoto atoll. The distribution by biotop and by bathymetric level is studied for the most abundant species ; they are Area ventricosa, Chama imbricata and Tridacna maxima for the endofauna, Rhinoclavis fasciatus, Vexillum cadaverosum, Fragum fragum and Lioconcha philippinarum for the epifauna. The Tridacna (14 million individuals — 530 tons of living matter) and the Area (38,5 millions — 340 tons) constitute most of the exemples of the malacological fauna, but the Mother-of-pearl, Pinctada margaritifera, intensively exploited in French Polynesia, is also the subject of quantitative estimates and breeding tests. Along with Molluscs, Corals (mainly Porites, Millepora, Montipora), Echinoderms (Halodeima atra) and Crustaceas (Brachiurs) represent a significant amount of the marine Invertebrates, while the sciaphil fauna (a few species of Sponges) is scarce compared to what is located on the outer slope. In this case we have a fauna typical of a closed atoll, where the uniformity and proliferation of 2 or 3 species in each zoological phylum is opposed to heterogeneousness and wealth of species found in open lagoons like Rangiroa and Mururoa.Richard Georges, Salvat Bernard, Millous Olivier.

Beyond the Cut Hunter: A Historical Epidemiology of HIV Beginnings in Central Africa

International audienceIn the absence of direct evidence, an imagined ''cut hunter'' stands in for the index patient of pandemic HIV/AIDS. During the early years of colonial rule, this explanation goes, a hunter was cut or injured from hunting or butchering a chimpanzee infected with simian immunodeficiency virus, resulting in the first sustained human infection with the virus that would emerge as HIV-1M. We argue here that the ''cut hunter'' relies on a historical misunderstanding and ecological oversimplification of human-chimpanzee (Pan Tro-glodytes troglodytes) interactions that facilitated pathogenic transmission. This initial host shift cannot explain the beginnings of the HIV/AIDS pandemic. Instead, we must understand the processes by which the virus became transmissible, possibly between Sangha basin inhabitants and ultimately reached Kinshasa. A historical epidemiology of the late nineteenth and twentieth centuries, provides a much-needed corrective to the major shortcomings of the cut hunter. Based on 62 oral historical interviews conducted in southeastern Cameroon and archival research, we show that HIV emerged from ecological, economic, and socio-political transformations of the late nineteenth and twentieth centuries. The gradual imposition of colonial rule built on and reoriented ecologies and economies, and altered older patterns of mobility and sociality. Certain changes may have contributed to the initial viral host shift, but more importantly, facilitated the adaptation of HIV-1M to human-to-human transmission. Our evidence suggests that the most critical changes occurred after 1920. This argument has important implications for public health policy, underscoring recent work emphasizing alternative pathways for zoonotic spillovers into human beings
