Though written corporate codes of ethics have been touted as a panacea for the embarrassments and uncertainties of the past two decades, the absence of clear evaluation procedures severely compromises their usefulness. An ethnographic study comparing development processes and compliance outcomes in large health care facilities and energy companies shows that neither of the two industries has encountered much success with a codes of ethics program. Companies that distribute copies of their code of ethics seldom ensure the process is completed (...) or that employees understand the purpose of the document, and staff responsible for the code give it a low priority relative to their overall responsibilities. Contrary to expectations, health care facilities are no more likely to develop or implement codes of ethics effectively than are energy companies. More extensive research is needed in order to generate the data necessary for the development of realistic standards for the evaluation of codes of ethics. (shrink)

Qu’est-ce qui fait qu’un discours atteint son effet? Comment évaluer celui-ci? Au premier siècle, Pseudo-Longin compose le traité Du Sublime et y étudie ce qui mène l’expression linguistique à son plus haut degré d’efficacité. Pour l’atteindre, un rôle fondamental est attribué à la phantasia, assimilée par la plupart des auteurs anciens à ce qui, dans le discours, produit des « images ». Le texte qui suit s’arrête à démontrer, d’une part, la place occupée par Pseudo-Longin dans le long débat philosophique (...) et rhétorique sur la phantasia et, d’autre part, sa contribution à la compréhension de celle-ci. Associée par métonymie à la vision, la phantasia s’adresse à l’ensemble des sensations et correspond à l’art de faire sentir le discours en chair propre. Réussie, elle permet la communication des sensations entre le discours, l’orateur et le public. (shrink)

Mucoidy and cytotoxicity arise from two independent modifications of the phenotype of the bacterium Pseudomonas aeruginosa that contribute to the mortality and morbidity of cystic fibrosis. We show that, even though the transcriptional regulatory networks controlling both processes are quite different from a molecular or mechanistic point of view, they may be identical from a dynamic point of view: epigenesis may in both cases be the cause of the acquisition of these new phenotypes. This was highlighted by the identity of (...) formal graphs modelling these networks. A mathematical framework based on formal methods from computer science was defined and implemented with a software environment. It allows an easy and rigorous validation and certification of these models and of the experimental methods that can be proposed to falsify or validate the underlying hypothesis. (shrink)

The language of “participant-driven research,” “crowdsourcing” and “citizen science” is increasingly being used to encourage the public to become involved in research ventures as both subjects and scientists....
