I would like to express my sincere gratitude to my supervisor Prof. Dr. Isabella Peters for supporting me during these past 6 years and for providing me guidance, encouragement, and kind advice throughout my research. She has been a key inspirational role model within my journey. I would also like to sincerely thank Prof. Dr. Klaus Tochtermann and Dr. Tamara Pianos for allowing me to work and research in such an excellent environment at ZBW (Leibniz Information Centre for Economic). Moreover, a special thanks to my ZBW colleagues, especially Dr. Nicholas Fraser and Steffen Lemke, for their useful and inspiring feedback on my PhD. Thank you to Dr. Guido Scherp and Dr. Atif Latif for their generous feedback that helped me throughout the way. I would also like to thank Bernd Schlünsen for his collaboration and support with integrating altmetrics data in some articles of EconBiz, which I used for my survey. In addition, I would also appreciate Thomas Arpe from the University of Kiel (CAU) for helping me with any server-related issues that were encountered when hosting and accessing my research data. Likewise, I owe thanks to Altmetric.com and Mendeley for offering me the opportunity to access and use the altmetric data for this research. To my wonderful husband, Nico Wichmann, I thank you not only for dealing with the challenges of PhD life but also for supporting me during hard times and while writing this thesis. Last but not least, I would like to thank my parents, who, in their worse days, showed support and motivated me to continue to study and research. Finally, I would like to thank my lovely sister, who was always there for me when I needed her most.
