This study investigates variations in survival following surgery for colo-rectal cancer in the Wessex region (part of southern England), using 5147 cases diagnosed between 1 September 1991 and 31 August 1995. Survival curve estimation by life tables and Cox's proportional hazards model were used...

The interest of social scientists in complexity theory has developed rapidly in recent years. Here, I consider briefly the primary characteristics of complexity theory, with particular emphasis given to relations and networks, non-linearity, emergence, and hybrids. I assess the 'added value'...

Recent research on studentification in the UK has examined the ways in which significant growth in student numbers over the last twenty years or so have led to marked change in the nature of the parts of cities in which clusters of students live. Yet these changes do not happen in isolation: the...
