Whether I was working on this project or just navigating the ups and downs of life, their presence meant everything to me.I would also like to thank my mother, Ana, and my ex-husband, Leo, for their unwavering patience and support throughout this entire process. Finally, I want to express my heartfelt gratitude to my children Mateo, Isabel, and Julia. They have been by my side every step of the way, being as my constant source of motivation and love. I dedicate this thesis to them.
