A university agenda of students as researchers was the inspiration for a student conference based on listening to children's and young peoples voices. (Wood, Bruner and Ross 1976). Students need to complete a small piece of research with children or...
Definitions. The modern state emerged in the 16th century in western Europe. Max Weber defines it as ' a human community that successfully claims the monopoly of the legitimate use of physical force within a given territory'. Andrew Heywood (2002)...
