Communication et Interculturation
2021
Interpersonal communication brings together individuals who try to make sense of one another in a given context. In this ongoing intersubjective process, they use culturally-structured knowledge and references to conjure up figures and styles rooted in identity-play. Whether in organisations, in the media, or in our open, cosmopolitan, liquid societies of late modernity, identities appear ever more present, ever more pressing. They are linked to the cultural traits that people use to “perform” and make sense of themselves and others in different social situations. The forms, figures and styles in circulation are mediated and updated through these everyday symbolic interactions, within a soc…
La gastronomie, question tarte à la crème ?
2024
La gastronomie fait partie de ces notions de sens commun que chacun se représente aisément mais que personne n'arrive à définir véritablement. Pourtant les approches ne manquent pas mais elles déplacent volontiers le curseur, entre le discours, les arts de la table, la culture et finalement tout un écosystème. On peut néanmoins se donner des repères pour fixer les idées, à défaut de trouver la formule ou la formulation idéale :- Repères historiques, bien sûr, qui font ou feraient de la gastronomie une "invention bien française". - Repères littéraires, entre toutes les classifications des "espèces de mangeurs" ou se distinguent gourmets et gourmands, et en mode dépréciatif, gloutons et goinf…
Online environmental activism and Internet use in the Indonesian environmental movement
2013
Author's version of an article in the journal: Information Development. Also available from the publisher at: http://dx.doi.org/10.1177/0266666913485260 This article investigates the use of the Internet among Indonesian environmental non-governmental organizations (ENGOs) and how this use influences the mobilizing structure of the environmental movement. The discussion is informed by an explorative study of nineteen Indonesian ENGOs working in the domain of forest protection. The study reveals that the Internet empowers the environmental activism of these organizations by enhancing opportunities for political participation. A main finding in the article is that well-established organization…
Antibiotics and food in the American press
2021
AbstractThe emergence of antimicrobial resistant infections from food is well documented in the scientific literature but, in this kind of matter, the public opinion is an important policy driver and is vastly forged by traditional media. Here, we propose a text mining study through about 500 articles from two reference daily U.S. newspapers to assess the media coverage of this issue. Our results indicate that, since the middle of the 80s, the two journals considered here adopted a very different narrative around the issue, echoing civil society concerns in one case and the official discourse in the other.
Características y visibilidad de las revistas españolas de ciencias de la salud en bases de datos
2015
Se describen las características de 207 revistas españolas de ciencias de la salud activas en 2014 y su visibilidad en seis bases de datos biomédicas y multidisciplinares. Scopus e Ibecs son las bases de datos que mayor número de revistas cubren, y Medline y WoS las que menos. La disciplina mejor representada es medicina, seguida de psicología, enfermería y farmacia. Se observa la práctica ausencia de revistas editadas exclusivamente en papel, la existencia de revistas publicadas en inglés, el aumento de versiones bilingües español-inglés y el acceso gratuito a los contenidos. El artículo incorpora el censo de revistas, que puede servir de referencia para los investigadores para selecciona…
Dietas confinadas: análisis del discurso de la prensa sobre la nutrición en tiempos de Covid-19
2021
The essential elements of the Spanish press’s discourse on nutrition guidelines during the Covid-19 health crisis are identified. To do this, the evolution of media representation is examined, with a semantic analysis of the news appearing in the national media in Spanish regarding nutrition and Covid-19. The analyzed period is from 31 January 2020 to 31 January 2021. The content search carried out using the Factiva database identified 117 records, which were analysed using T-LAB software. The results reveal that the press warned of hoaxes regarding nutrition during the study period. Four semantic groups are identified, informing about the most appropriate eating patterns according to the d…
Learning Molecular Classes from Small Numbers of Positive Examples Using Graph Grammars
2021
We consider the following problem: A researcher identified a small number of molecules with a certain property of interest and now wants to find further molecules sharing this property in a database. This can be described as learning molecular classes from small numbers of positive examples. In this work, we propose a method that is based on learning a graph grammar for the molecular class. We consider the type of graph grammars proposed by Althaus et al. [2], as it can be easily interpreted and allows relatively efficient queries. We identify rules that are frequently encountered in the positive examples and use these to construct a graph grammar. We then classify a molecule as being conta…

Introduction of Cytochrome P-450 Genes into V79 Chinese Hamster Cells to Generate New Mutagenicity Test Systems
1989
Usually, cultivated cells have poor capabilities to metabolize promutagens and procarcinogens. This is particularly true for cells that grow fast and have a high cloning efficiency, as is the case with V79 Chinese hamster cells. For this reason, these cells are being extensively used in mutagenicity tests. But, due to the fact that particularly these cells lack cytochrome P-450 activities, promutagens and procarcinogens have to be incubated with an exogenous metabolizing system, e.g. liver homogenate preparations, in order to generate reactive metabolites. These extracellularly generated metabolites are then given to V79 cells in order to check for their potency to mutate the chromosomal DN…
Interrogation of genomes by molecular copy-number counting (MCC)
2006
Human cancers and some congenital traits are characterized by cytogenetic aberrations including translocations, amplifications, duplications or deletions that can involve gain or loss of genetic material. We have developed a simple method to precisely delineate such regions with known or cryptic genomic alterations. Molecular copy-number counting (MCC) uses PCR to interrogate miniscule amounts of genomic DNA and allows progressive delineation of DNA content to within a few hundred base pairs of a genomic alteration. As an example, we have located the junctions of a recurrent nonreciprocal translocation between chromosomes 3 and 5 in human renal cell carcinoma, facilitating cloning of the br…
