Quel est le sens de l’équation "Le media est le message?

Il y a un malentendu en ce qui concerne l’expression « Le media est le message » de Marshall McLuhan, car l'on méprend le sens du mot anglais médium pour l’acception canadienne de média, comme dans l’expression mass media/médias de masse. Dans cet article, Mark Federman, nous apprend qu’un media est une extension de l’être humain et que le message est le changement que le media suscite dans notre environnement.

'Le récit de vie(s)': immobility and fluidity in Ying Chen's works

The article explores the themes of fluidity and immobility in the works of Ying Chen, a francophone Chinese writer whose early texts are associated with 'les écritures migrantes' of Quebec. From her third book, the narratives take on a post-death perspective and the narrator moves between her present existence and past lives.

Analysis of DNA processing reactions in bacterial conjugation by using suicide oligonucleotides

Protein TrwC is the conjugative relaxase responsible for DNA processing in plasmid R388 bacterial conjugation. TrwC has two catalytic tyrosines, Y18 and Y26, both able to carry out cleavage reactions using unmodified oligonucleotide substrates. Suicide substrates containing a 30-Sphosphorothiolate linkage at the cleavage site displaced TrwC reaction towards covalent adducts and thereby enabled intermediate steps in relaxase reactions to be investigated. Two distinct covalent TrwC–oligonucleotide complexes could be separated from noncovalently bound protein by SDS–PAGE. As observed by mass spectrometry, one complex contained a single, cleaved oligonucleotide bound to Y18, whereas the other contained two cleaved oligonucleotides, bound to Y18 and Y26. Analysis of the cleavage reaction using suicide substrates and Y18F or Y26F mutants showed that efficient Y26 cleavage only occurs after Y18 cleavage. Strand-transfer reactions carried out with the isolated Y18–DNA complex allowed the assignment of specific roles to each tyrosine. Thus, only Y18 was used for initiation. Y26 was specifically used in the second transesterification that leads to strand transfer, thus catalyzing the termination reaction that occurs in the recipient cell.

Area factors and suicide: 5-year follow-up of the Northern Ireland population

Background: Suicide rates vary markedly between areas but it is unclear whether this is due to differences in population composition or to contextual factors operating at an area level.
Aims: To determine if area factors are independently related to suicide risk after adjustment for individual and family characteristics.
Method: A 5-year record linkage study was conducted of 1 116 748 non-institutionalised individuals aged 16-74 years, enumerated at the 2001 Northern Ireland census.
Results: The cohort experienced 566 suicides during follow-up. Suicide risks were lowest for women and for those who were married or cohabiting. Indicators of individual and household disadvantage and economic and health status at the time of the census were also strongly related to risk of suicide. The higher rates of suicide in the more deprived and socially fragmented areas disappeared after adjustment for individual and household factors. There was no significant relationship between population density and risk of suicide.
Conclusions: Differences in rates of suicide between areas are predominantly due to population characteristics rather than to area-level factors, which suggests that policies targeted at area-level factors are unlikely to significantly influence suicides rates.

L’Utilisation D’Entretiens Quantitatifs Pour Détecter L’influence des Parents Dans le Développement de Compétences Sportives Chez Les Athlètes

Past research has indicated that parents influence children’s sport performance, but studies using qualitative methodologies and lacking comparison groups have failed to outline specific parent behaviors that constitute support, pressure, involvement, and resource provision at each stage of development. This paper presents a quantitative methodology that assesses specific, observable, verifiable parent behaviors across development, allowing future researchers to highlight differences in parental behaviors of athletes who reach high levels of performance and those who do not. The combined survey and interview methodology examines parents’ demographic information, children’s involvement in sporting activities, and the nature of parents’ involvement in those activities. A case study conducted with the parents of three Canadian junior ice hockey athletes using this methodology found parents’ invested time and specific behaviors changed throughout the development of the athlete.
