I declare that I wrote this master’s thesis on my own and that I used only the sources listed in the bibliography.
I agree with the placing of this thesis in the library of the Faculty of Education at Masaryk University and with the access of this thesis for academic purposes.

I would like to thank my supervisor Mgr. Martin Adam Ph.D. for his support and guidance and his prompt and useful ideas and recommendations. I would also like to thank my children Tristen and Halina for being so understanding and encouraging, and I hope to be able to repay them one day when they write their theses. Finally, I want to thank my husband Jason and dedicate this thesis to him, as without his help, support and love I would not have been able to succeed in this difficult endeavor.
