The summer school will consist of lectures and practical work for master and

  To prepare and streamline the summer school, the consortium organized a
teacher training in Pula, Croatia. This was an event of five full days,
organized by Tihana Galinac Grbac and Neven Grbac. The Juraj Dobrila University
of Pula is very concerned with the sustainability issues. The education,
research and management are conducted with sustainability goals in mind.
  The contributions in the proceedings were reviewed and provide a good
overview of the range of topics that will be covered at the summer school. The
papers in the proceedings, as well as the very constructive and cooperative
teacher training, guarantee the highest quality and beneficial summer school
for all participants.
