Professionalization of the engineer, from the perspective of sociology of technology, registrant in the statements of principle and Canadian standards of accreditation of university engineering programs. The question of the development of technologies (production, dissemination and appropriation) is attached in all respects with personal and social qualities of which refer engineer schools of engineering and regulatory bodies. The engineering profession s’roots from elsewhere in industrial ans social sectors increasingly sensitive to the social dimensions of technology, considering the new dynamics that (...) s’are attached with regard to the technology impacts on society and businesses.

Hull et al.'s analysis of operant behavior in terms of interaction and replication does not seem consistent with a genuine selection model. The putative replicators do not replicate, and the overall process is more reminiscent of directed mutation than of natural selection. General analogies between natural selection and operant reinforcement are too superficial to be of much scientific use.

The second international Chromatiques whiteheadiennes conference was devoted exclusively to the exegesis and contextualization of Whitehead's Science and the Modern World (1925). In order to elucidate the meaning and significance of this epoch-making work, the Proceedings are designed to form "companion" volume. With one paper devoted to each of its thirteen chapters, the Proceedings aim, on the one hand, to identify the specific contribution of each chapter to Whitehead's own research program - that is to say, to put its categories (...) into perspective by means of an internal analysis- and, on the other hand, to identify its global impact in the history of ideas.

Les relations de la machine et de la pensée sont aussi anciennes qu'énigmatiques, toujours en attente d'une solution. C'est un mythe dont s'abreuve la philosophie. Il est ici repris en fonction de notre conjoncture, la science-fiction avec Matrix, la logique et l'ordinateur avec Turing, enfin l'élaboration théorique avec le cognitivisme et la non-philosophie. Ces essais ont été élaborés dans un même esprit au sein d'une équipe dont les jeunes philosophes partagent le désir commun de renouveler le style philosophique par une (...) discipline de philo-fiction. -/- The relationship between the machine and thought is as old as it is enigmatic, always awaiting a solution. It's a myth that philosophy feeds on. Here it is revisited in the context of our current situation: science fiction with Matrix, logic and the computer with Turing, and theoretical development with cognitivism and non-philosophy. These essays have been drawn up in the same spirit by a team of young philosophers who share a common desire to renew the philosophical style through a discipline of philo-fiction. (shrink)

Theiler's virus is a picornavirus of mouse which causes an acute encephalomyelitis followed by a persistent infection of the white matter resulting in chronic inflammation and demyelination. This disease has been studied as a model for multiple sclerosis. Inbred strains of mice are either resistant--they clear the infection after the acute encephalomyelitis--or susceptible to persistent infection and demyelination. Susceptibility is a polygenic trait which has been analyzed using methods of association with “candidate” genes, and linkage analysis after a complete genome (...) scan. The H-2Db gene is responsible for an efficient CTL response which makes some strains resistant. Non H-2 genes responsible for the susceptibility of other strains have been mapped by linkage analysis to the Ifng and, possibly, the Mbp loci. The analysis of a set of congenic mice ruled out the possiblity that the relevant gene codes for interferon gamma, and showed that the region around Ifngprobably contains two susceptibility genes. The analysis of mutant mice showed further that the Mbp gene, which codes for the myelin basic protein, has a major effect on viral persistence.

Self-regulated learning is critical for learning across tasks, domains, and contexts. Despite its importance, research shows that not all learners are equally skilled at accurately and dynamically monitoring and regulating their self-regulatory processes. Therefore, learning technologies, such as intelligent tutoring systems, have been designed to measure and foster SRL. This paper presents an overview of over 10 years of research on SRL with MetaTutor, a hypermedia-based ITS designed to scaffold college students’ SRL while they learn about the human circulatory system. (...) MetaTutor’s architecture and instructional features are designed based on models of SRL, empirical evidence on human and computerized tutoring principles of multimedia learning, Artificial Intelligence in educational systems for metacognition and SRL, and research on SRL from our team and that of other researchers. We present MetaTutor followed by a synthesis of key research findings on the effectiveness of various versions of the system on learning outcomes. First, we focus on findings from self-reports, learning outcomes, and multimodal data and their contributions to our understanding of SRL with an ITS. Second, we elaborate on the role of embedded pedagogical agents as external regulators designed to scaffold learners’ cognitive and metacognitive SRL strategy use. Third, we highlight and elaborate on the contributions of multimodal data in measuring and understanding the role of cognitive, affective, metacognitive, and motivational processes. Additionally, we unpack some of the challenges these data pose for designing real-time instructional interventions that scaffold SRL. Fourth, we present existing theoretical, methodological, and analytical challenges and briefly discuss lessons learned and open challenges. (shrink)

Text in French. Les 31 mai, 1er et 2 juin 2006, la Faculté de Théologie de l'Université catholique de Louvain a organisé, en collaboration avec le Centre de philosophie pratique Chromatiques whiteheadiennes, un colloque international consacré á la pensée d'Alfred North Whitehead. Les échanges ont privilégié les aspects les plus actuels d'une pensée apte á rencontrer les défis contemporains. Rejoindre l'actualité de Whitehead tant en science et en philosophie qu'en théologie suppose de pratiquer une interdisciplinarité qui est au coeur de (...) ses intuitions. Le dialogue entre scientifiques, philosophes et théologiens a permis d'apporter des précisions importantes sur la manière whiteheadienne d'appréhender les sphères en interaction de la religion, de la science et de la politique.

In this note we introduce the notion of K–player additive extension of a symmetric two-player game and prove a result relating the equilibria in mixed strategies in the two games. Then we apply the result to the Borda electoral competition game.

In the area of investment, responsibility may be expressed via four types of ethical concern: value-based ethics resulting in the exclusion of so-called "vicious" companies from the investment portfolio; fructification-oriented ethics with a view to long-term investment; consequence-based ethics aimed at initiating a behavioural change in the investment target; and ethics envisaged as a discriminating criterion in the search of the best financial performance. No single formula of responsible investment is available, and the "responsible" approach necessarily implies the active involvement (...) of a free acting subject striving to tackle fundamental ethical issues. The practice of responsible investment cannot be reduced to simply applying a particular legal rule or mathematical formula. (shrink)

Similar to parasites, cancer cells depend on their hosts for sustenance, proliferation and reproduction, exploiting the hosts for energy and resources, and thereby impairing their health and fitness. Because of this lifestyle similarity, it is predicted that cancer cells could, like numerous parasitic organisms, evolve the capacity to manipulate the phenotype of their hosts to increase their own fitness. We claim that the extent of this phenomenon and its therapeutic implications are, however, underappreciated. Here, we review and discuss what can (...) be regarded as cases of host manipulation in the context of cancer development and progression. We elaborate on how acknowledging the applicability of these principles can offer novel therapeutic and preventive strategies. The manipulation of host phenotype by cancer cells is one more reason to adopt a Darwinian approach in cancer research. -/- . (shrink)
