and due to the far reach of the French Empire during the colonial era, many schools have been created around the world based on the ENS model, from Haiti (in Port-au-Prince) to Vietnam (in Hanoi) to the Maghreb (in Tunis, Casablanca, Oran, and Rabat to name but a few) and Subsaharan Africa (in Nouakchott, Libreville, Yaoundé, Dakar, Niamey, Bangui for example). ENS maintains good relations and close links with these institutions. In 2005, ENS opened a branch at the East China Normal University (ECNU) in Shanghai, whose French name was changed to École normale supérieure de l'Est de la Chine to reflect the agreement, and a joint doctoral program between the two institutions was launched. ENS welcomes international researchers for one-year stays through the mediation of the Paris Institute of Advanced Research and the Villa Louis-Pasteur. The Blaise Pascal, Marie Curie, Condorcet and Lagrange research places (chaires) also allow researchers from abroad to stay for more than a year at ENS laboratories. ENS also is a member of the Franco-Chinese laboratory Saladyn since 2013. It has been hosting an antenna of New York University's Erich Maria Remarque Institute since 2007. Furthermore, ENS has partnerships for research at Master's and Doctorate levels, sending its students to universities around the world to complete their tuition. It also shares thesis habilitation with universities abroad, meaning that somes theses can be written with support from both the ENS and one of its partner institutions. It is also customary for students in the literary and linguistic subjects to go to teach for one year in universities abroad with the position of junior fellows. These exchange and cooperation programs link ENS with universities such as the University of Beijing in China, Freie Universität Berlin in Germany, the universities of Cambridge, Edinburgh and Oxford in the United Kingdom, Trinity College in Dublin, McGill University in Montréal, and the universities at Berkeley, Columbia, Cornell, Harvard, Princeton, Stanford, and Yale in the United States. Academics Publishing Since 2001, the École normale supérieure's internet portal, called Diffusion des savoirs ("Spreading knowledge") has offered access to more than 2000 recordings of conferences and seminars that have taken place at the school, in all sciences natural and social. The school also has launched its own short conference platform, Les Ernest, which shows renowned specialists speaking for fifteen minutes on a given subject in a wide scope of disciplines. In 1975 the school
