We present a spectral analysis of the UV-bright star vZ 1128 in M3 based on observations with the Far Ultraviolet Spectroscopic Explorer (FUSE), the Space Telescope Imaging Spectrograph (STIS), and the Keck HIRES echelle spectrograph. By fitting the H i, He i, and He ii lines in the Keck spectrum with non-LTE H-He models, we obtain T eff = 36,600 K, log g = 3.95, and log N (He)/N (H) = −0.84. The star's FUSE and STIS spectra show photospheric absorption from C, N, O, Al, Si, P, S, Fe, and Ni. No stellar features from elements beyond the iron peak are observed. Both components of the N v λ1240 doublet exhibit P Cygni profiles, indicating a weak stellar wind, but no other wind features are seen. The star's photospheric abundances appear to have changed little since it left the red giant branch (RGB). Its C, N, O, Al, Si, Fe, and Ni abundances are consistent with published values for the red-giant stars in M3, and the relative abundances of C, N, and O follow the trends seen on the cluster RGB. In particular, its low C abundance suggests that the star left the asymptotic giant branch before the onset of third dredge-up.
The emergence and success of web platforms nurtured a trend within social studies: "Hyperlink is dead!". Capturing their users into mobile applications and specialised web interface to propose them a specific user experience (and business model), the platforms indeed created new information silos in the open World Wide Web space. The simplified availability of user behavioural data through these platforms APIs reinforced this idea in academic communities by providing scholars with an easy way to collect rich user centric data for their research. After discussing the methodological aspects of the web divide between platforms and classical websites, we will argue that although it becomes more and more invisible, the hyperlink, modern incarnation of intertextual links between documents, is still a central and structural element of the web. Hyperlinks remain an invaluable resource to turn the web into a research field in spite of the complexity to collect, manipulate and curate them. We will illustrate those methodological challenges by describing the choices we made in designing Hyphe, a tool dedicated to the creation of web corpora tailored for mining hypertexts.

humanités numériques L'atelier de méthodes de Sciences Po : apprendre, aider, rassembler Résumés pants (researchers, students and others) sign up for a 3-hour session, and present their issue -which can be technical or methodological -to a team of supervisors from diverse backgrounds and profiles providing support that is as individualised as possible. In this article, we will explain the organisation and founding values of the METAT, as well as give our feedback as supervisors and organisers. This description will be enriched with the analysis of data built from the reports and registration form. We hope this article can give teachers in the humanities and social sciences information on the growing demand for digital training, provide feedback on a project-based digital teaching, and maybe inspire other organisations to create their own methods workshop.enseignement, pédagogie par projet, transmission horizontale des savoirs, collaboration teaching, project-based pedagogy, horizontal transmission of knowledge, collaboration Bien que le nom du laboratoire soit un nom propre, l'équipe a adopté il y a plusieurs années la graphie « médialab », sans majuscule, pour des raisons stylistiques et afin de se distinguer du Media Lab du MIT. Dans le présent article, nous respectons cet usage qui s'écarte des conventions orthotypographiques de la revue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
