Previous Freshers’ Weeks Each Freshers’ Week is organised around a "leitmotif", a key topic that among other things includes a case study, which students focus on during the week. Working in case study groups Students are allocated to one of the 60 groups and each group consists of about 24 people. Working on the case study, students address the interdisciplinary subject to which they have an emotional and contextual association. Freshers’ Week topics of recent years In 2007, the topic was called "Work-Life Balance", in 2008 “Energy: The challenge of sustainable energy supply", and in 2009 "Intercultural conflicts and cooperation", in 2010 “Media - Understanding, experiencing and producing", in 2011 it dealt with "Food Security - Escaping from hunger". As a result of the bilingual introduction of the Freshers’ Week, a German and English version of the case study is now prepared for two consecutive Freshers' Weeks. In 2012 and 2013, the topic focused on "Development Strategies – A country sets out to shape its future”. In 2014 and 2015, the case study was called “Outlook Switzerland – risks and opportunities”. 2016 and 2017 was all about "Swiss retirement provision risks – campaign challenge". This year's case study will look at the highly topical issue of "Digitalisation – Switzerland in a time of change".
