    Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014 July–2017 July). This is the third data release for SDSS-IV, and the 15th from SDSS (Data Release Fifteen; DR15). New data come from MaNGA—we release 4824 data cubes, as well as the first stellar spectra in the MaNGA Stellar Library (MaStar), the first set of survey-supported analysis products (e.g., stellar and gas kinematics, emission-line and other maps) from the MaNGA Data Analysis Pipeline, and a new data visualization and access tool we call "Marvin." The next data release, DR16, will include new data from both APOGEE-2 and eBOSS; those surveys release no new data here, but we document updates and corrections to their data processing pipelines. The release is cumulative; it also includes the most recent reductions and calibrations of all data taken by SDSS since first light. In this paper, we describe the location and format of the data and tools and cite technical references describing how it was obtained and processed. The SDSS website (www.sdss.org) has also been updated, providing links to data downloads, tutorials, and examples of data use. Although SDSS-IV will continue to collect astronomical data until 2020, and will be followed by SDSS-V (2020–2025), we end this paper by describing plans to ensure the sustainability of the SDSS data archive for many years beyond the collection of data

    Managing Infidelity: A Cross-Cultural Perspective

    Full text link
    Anthropologists have not systematically examined extramarital affairs. Our cross-cultural study found that within every culture men and women actively resort to mate-guarding tactics to control their mate\u27s extramarital behavior. A person\u27s level of interest and involvement does not change with a culture\u27s notion of descent, level of social complexity, or the degree to which a culture is normatively permissive or restrictive in sexual matters. In effect, sexual propriety is the presumed right of both sexes. Our findings are consistent with both the sexual jealousy and the pair-bond hypotheses, which hold that every marriage or love relationship is organized around a presumption of sexual propriety

    Lectrices d'Ancien RĂ©gime

    La lecture et le lectorat ont fait, depuis une vingtaine d’annĂ©es, l’objet de nombreuses Ă©tudes, qui ont mis en Ă©vidence des disparitĂ©s importantes entre un lectorat masculin et fĂ©minin. La lecture est un lieu socialement construit de la diffĂ©rence des sexes. Se manifeste, dĂšs le XIVe siĂšcle, un processus de sĂ©cularisation dans les pratiques de lecture Ă  mettre en relation avec un phĂ©nomĂšne de dĂ©sacralisation du livre. La lecture au fĂ©minin est l’enjeu de dĂ©bats moraux oĂč s’y affirme sa dangerositĂ©. Dans le mĂȘme temps apparaissent des prises de position en faveur du contrĂŽle des lectures fĂ©minines qui s’inscrivent dans une conception du partage des pouvoirs de l’écrit en corrĂ©lation avec un partage hiĂ©rarchique des savoirs. Parce qu’elle est transgression, sĂ©duction, perversion, la lecture et la lectrice se dĂ©ploient en un imaginaire dont la littĂ©rature s’est emparĂ©e pour en proposer des reprĂ©sentations multiples et protĂ©iformes. Territoires de l’historien et espaces littĂ©raires ont Ă©tĂ© dans cet ouvrage confrontĂ©s en une approche transsĂ©culaire, transdisciplinaire, Ă  partir de l’étude de documents multiples, bibliothĂšques, correspondances, manuels, iconographie et de textes littĂ©raires. Il constitue une contribution importante Ă  la construction d’une histoire sociale et culturelle de la lecture fĂ©minine. Il propose un bilan des savoirs de ces derniĂšres dĂ©cennies et de nouveaux jalons pour les Ă©tudes Ă  venir
