The network is known as c.a.s.e. collective. It organizes a meeting ground for critical constructivist security research in Europe that uses three schools of thought as its basis: the Copenhagen School, the Paris School, and the Welsh School. People from the Paris meeting drafted a manifesto for the second generation of Critical Approaches to Security, which is forthcoming in Security Dialogue, a major journal in critical security studies.
