Acknowledgement Firstly, I would like to thank the residents of the Gemeinschaftsunterkünft at Hofheim Am Taunus, who made this thesis possible by patiently answering my questions. Secondly, I extend my gratitude to all the friends I have made along this wonderful journey over the past two years, in both Darmstadt and Barcelona, who have made my life easier and light despite the trying times. Cheers! Thirdly, I sincerely thank Apen Ruiz Martinez, my supervisor. She has been an important source of clarity and support, without whose guidance, this thesis would not materialise. Finally, I would like to thank my family for the unconditional love and constant encouragement.
