Eh?

I'm reading through the last 4 months of email here at work and I come
across an invitation to a conference.

"An International Conference on Young People:
New Horizons for Youth Participation and Democracy

Introduction
Social and political discourses across the world continue to
problematise and criminalise young
people and are built on a language of fear, protection, control and
surveillance. This is neither
helpful in engaging or empowering young people nor is it acceptable in
terms of meeting their
democratic rights."

Can someone tell me when "problematise" became a word?

This is for an academic conference, hosted by the faculty of education
at Strathclyde.

I despair.

Sounds like the conference itself might be heading in the right direction.

But "problematise"?
