Interpreting social issues: Museum theatre’s potential for critical engagement

Museum theatre and its potential within museum education is explored at the Museum Education and Research Laboratory at the University of Thessaly, Greece. There, the leading research project Museums and Education: methods of approaching and interpreting museum objects’aims to address how, over the last few decades, museum theatre has been in ever-increasing use to vocalize the sensitive issues of a multicultural society and marginalized social communities. Recent studies highlight museum theatre evoking empathy and critical engagement in the audience with the subject-matter of the performance. One such performance was organized by the School of Drama at the Aristotle University of Thessaloniki and studied in depth. Titled Voices of the City: Historical Routes through Theatre, the performance embodied controversial social issues, and its implementation was evaluated using qualitative methodology to examine the responses of visitors

A comparison of Euclidean and Heisenberg Hausdorff measures

We prove some geometric properties of sets in the first Heisenberg group whose Heisenberg Hausdorff dimension is the minimal or maximal possible in relation to their Euclidean one and the corresponding Hausdorff measures are positive and finite. In the firs, case we show that these sets must be in a sense horizontal and in the second case vertical. We show the sharpness of our results with some examples.Peer reviewe

Prove di consistenza e indipendenza nella Teoria degli insiemi

Nella tesi dopo una breve introduzione a carattere storico si espongono risultati di consistenza e indipendenza per assiomi della teoria degli insiemi ZF. I risultati sono ottenuti mediante modelli elementari, oppure sono risultati derivati sulla base dell'assunzione di consistenza di ZF (per i noti risultati di Gödel); in particolare si discutono le relazioni tra ZF e l'assioma di regolarità (buona fondazione)
