Analysis and interpretation of students' dialogues - Baker

Research in the Learning Sciences gives a privileged place to the analysis of interactions between social actors and with themilieux in which their collective activities are situated. In this presentation, and in this context, I want to engage in an inquiryabout the distinction between the epistemological concepts of "analysis" and of "interpretation, originating in physical andhuman sciences, respectively. On the basis of a critical perspective on what might be termed the 'standard' approach toanalysing educational interactions (systematic application of determinate coding schemes), I will discuss the problem of the unitof analysis of the processes of collective thinking-in-dialogue, and propound a ...

Approches multiéchelles du cerveau visuel : des échos synaptiques à la perception des formes et du mouvement (série : Colloquium Jacques Morgenstern)

Résumé en anglais seulement, mais la conférence est en français.The field of neuromorphic computation has grown from the idea that inspiration for future computational architectures can be gained from a better understanding of information processing in biological neural networks. Information coding in our brain is both digital, in terms of output spike timing, and analogue, produced by the slower, subthreshold changes in membrane voltage resulting from a continual barrage of synaptic inputs. These small and ever-changing voltage fluctuations in the neuronal membrane potential of the single ...

Géopolitique du patrimoine ; Perspectives croisées Chine-Afrique

Increasing State and local community interest in Intangible Cultural Heritage (ICH) highlights, as with other UNESCO programmes, the stakes that now crystallize different acceptations of the notion of heritage and the recomposition of related “tradition” and “modernity” paradigms. New players like the Popular Republic of China are emerging, and what might more generally be referred to as a “geopolitics of heritage” is taking form. Following the seminars held under the auspices of the ANR “Chinese Cultural Spaces in Africa” activities since 2012, this panel aims both to continue to share the (re)constructions, implications and recompositions of processes of patrimonialization in ...

Distance Learning, Intercultural Communication and ICT

In this interview, Kumiko AOKI 青木久美子 tells us about her academic background, her experiences with regard to different scientific institutions and international workplaces as well as about her research experiments. She compares the international employment of e-learning among various contexts and institutions of higher education. She particularly focuses on the teaching and learning of intercultural communication. She explains that in Japan, the diffusion of e-learning among higher education institutions is very behind among all the OECD nations despite the fact that the Japanese Ministry of Education, Culture, Sports and Technology (MEXT) has been trying hard to promote e-learning ...

Folding Turing is hard but feasible

We introduce and study the computational power of Oritatami, a theoretical model to explore greedy molecular folding, by which the molecule begins to fold before waiting the end of its production. This model is inspired by our recent experimental work demonstrating the construction of shapes at the nanoscale by folding an RNA molecule during its transcription from an engineered sequence of synthetic DNA. While predicting the most likely conformation is known to be NP-complete in other models, Oritatami sequences fold optimally in linear time. Although our model ...
