La circulation et l'usage des supports enregistrés dans les musiques populaires en Ile de France
2007
Ce rapport est consacré à la façon dont les jeunes musicien-n-e-s apprennent et pratiquent les musiques populaires et plus particulièrement au rôle des supports enregistrés et des machines de reproduction sonore. Il est divisé en deux parties.D'abord l'exposé préliminaire des prémisses historiques et sociologiques qui ont servi de socle à cette recherche (1. Les instructeurs non-humains)La deuxième partie rend compte d'une enquête de terrain menée en Ile de France et, de façon plus limitée, dans l'agglomération nantaise en 2006 et 2007 (2.

The Nanoeconomics of Firm‐Level Decision‐Making and Industry Evolution : Evidence from 200 Years of Paper and Pulp Making
2020
Research summary We explore the qualitative differences in entries and exits over time. Using qualitative and quantitative data on 96 firms over 200 years, we study industry evolution from the perspective of individual decision‐making situations. Our historical and statistical analyses reveal the vital role of technology investments in determining firm outcomes, and the technological, institutional and governance dynamics that lead firms to invest or to abstain. Our main theoretical and methodological contribution concerns the importance of the multiplicity of firm‐level rationalities and decisions as fundamentals in theorizing on industry evolution. Managerial summary What determines firm …
46 viikkoa pandemian keskellä : vuosien 1918-1919 influenssapandemia Iso-Britanniassa The Manchester Guardianin, The British Medical Journalin ja par…
2016
Tutkimus keskittyy vuosien 1918 - 1919 espanjantautina tunnettuun influenssapandemiaan Iso-Britanniassa kolmen aineistokokonaisuuden: sanomalehti The Manchester Guardianin, lääketieteellisen The British Medical Journal -lehden ja Iso-Britannian parlamentissa käytyjen keskusteluiden kautta. Tarkastelun kohteena on influenssasta poliittisella, professionaalisella, julkisella ja paikallisella tasolla käytyjen keskusteluiden luonne, niiden teemat ja keskusteluissa tapahtuneet muutokset kolmen eri influenssa-aallon aikana, sekä eri tasoilla käytyjen keskusteluiden mahdolliset erot ja yhtäläisyydet. Tutkimus havainnollistaa influenssapandemian yhteiskunnallisten vaikutusten laaja-alaisuutta aina …
Health Beliefs of Wearing Facemasks for Influenza A/H1N1 Prevention : A Qualitative Investigation of Hong Kong Older Adults
2019
Although vaccination is the first-line strategy controlling and preventing influenza A/H1N1 for older adults, personal protective measures, such as wearing facemasks, are also important preventive behaviors to reduce the risk of becoming infected with influenza A/H1N1 during a pandemic. In the current study, we aimed to explore the belief-related psychological factors of wearing facemasks for influenza A/H1N1 prevention in a sample of Hong Kong older adults. Community-dwelling Chinese adults (N = 137) aged between 65 and 80 years (Mage = 75.10; SDage = 6.49) participated in semistructured interviews. Data were analyzed using theoretical thematic analysis and identified themes were matched d…
Towards a digital model to edit the different paratextuality levels within a textual tradition
2008
In the textual tradition of a literary work, our sources (manuscripts, printed books etc.) commonly bear, together with the "main text", different kinds of "paratexts" commenting on it (including interlinear annotations, glosses, scholia, footnotes, modern scholarly introductions and commentaries, and many others). This article proposes a unified model for a document-based digital critical edition including both the 'main texts' and the 'paratexts' as they appear in different single sources. The problematic aspects of such an "enlarged" digital edition are discussed, including the relations between the different 'paratexts' and the 'main text' they refer to 'within each single textual sourc…

[35] Determination of oxidized glutathione in blood: High-performance liquid chromatography
1994
Publisher Summary The measurement of glutathione status is important in determining oxidative stress in tissues and biological fluids. The ratio of reduced to oxidized glutathione (GSH/GSSG) is a good indicator of the oxidative stress that may occur under physiological and pathological conditions. Changes in GSSG levels have been considered as intracellular signals able to modulate enzyme activity. Thus, it is important to have accurate methods to determine GSSG in biological fluids and in cells. In many cases, it is possible to use tissues, such as liver, muscle, or brain to determine GSH/GSSG. However, especially in human studies, samples from these tissues are not readily available; the …
Lignin-based activated carbon-supported metal oxide catalysts in lactic acid production from glucose
2021
In this study, heterogeneous biomass-based activated carbon-supported metal oxide catalysts were prepared and tested for lactic acid production from glucose in aqueous solution. Activated carbons were produced from hydrolysis lignin by chemical (ZnCl2) or steam activation and modified with a nitric acid treatment and Sn, Al, and Cr chlorides to obtain carbon-based metal oxide catalysts. The modification of the carbon support by nitric acid treatment together with Sn and Al oxides led to an increase in lactic acid yield. The highest lactic acid yield (42%) was obtained after 20 minutes at 180 °C with the Sn/Al (5/2.5 wt.%) catalyst on steam-activated carbon treated by nitric acid. Reusabilit…
