Andrew Nevins - Labex 2021 - Lecture 2 - Nasality: Enhancement, Position, and Place of Articulation parrt 2

Lectures 1-2: Nasality: Enhancement, Position, and Place of Articulation We propose that contour nasals such as [mb,mb] come from three principal sources. One source, articula- torily driven, comes from underlying voiced stops, as nasal venting in order to sustain voicing. The other, perceptually driven, comes from underlying nasal consonants, as shielding next to contrastively oral vow- els. Although both of these first processes are phonetically well motivated, we argue that the contoured allophones specifically arise in languages in which systemic or phonotactic restrictions allow for easy re- coverability of the corresponding underlying segment. Finally, we present a few cases of contour nasals in preconsonantal contexts ...

IFEA Histoire 2020-2021 Provincial Perspectives for the Ottoman Reforms during the Tanzimat Era

The talk will be about Yonca Köksal’s recent book The Ottoman Empire in the Tanzimat Era: Provincial Perspectives from Ankara to Edirne (Routledge, 2019). It will explain the Ottoman reforms and their variation across the two provinces and the crucial role of local intermediaries such as notables, tribal leaders, and merchants. It attempts to understand the Tanzimat as a process of negotiation and transformation between the state and local actors. The author argues that the same reform policies produced different results in Edirne and Ankara. The talk will explain how factors such as socioeconomic conditions and historical developments played a role in ...

Une introduction à la bio-inspiration marine

Tarik Chekchak, directeur du pôle Biomimétisme à l'Institut des Futurs Souhaitables, parle dans cette vidéo de biomimétisme marin. Il situe tout d'abord cette approche dans un cadre plus général de bio-inspiration et de développement durable. Puis il montre, sur la base d'exemples, que ce biomimétisme doit s'inspirer des grandes recettes du succès des organismes marins pour filtrer, s'ancrer, se déplacer, se protéger ou encore communiquer.

La bio-inspiration marine : quelques exemples

Nadia Améziane, professeure du Muséum national d'Histoire naturelle, apporte dans cette vidéo des exemples de bio-inspiration marine. En s'appuyant sur différents organismes marins, elle met en évidence la diversité des applications de cette bio-inspiration dans des domaines comme la santé, l'architecture, l'ingénierie ou encore la chimie. Elle souligne la nécessité de lier ces recherches à l'enjeu de conservation de la biodiversité.
