Abstract: Plenty of research has been done to analyze and classify the sentiment (i.e., the positive, neutral or negative stance) of social media posts during crises, conflicts, and protests using machine learning techniques. However, fewer works have examined the impact

Mobile crisis notification systems, including apps such as NINA, have been shown around the world to be successful in alerting the public to disasters. Activists in certain countries such as Afghanistan, especially since the Taliban takeover, face unique threats such

This thesis addresses the feature of "app camouflage," which is an approach to mitigate digital surveillance and censorship, particularly in contexts where individuals may be at risk of violence or other harm. The growing number of individuals with internet access

Abstract: Das Konzept des Public Core of the Internet hat sich seit der initialen Veröffentlichung 2014 stetig verbreitet und ist ein viel diskutierter Teil der Internet Governance geworden. Internationale Anerkennung hat das Konzept durch die Aufnahme in die GCSC-Normen sowie

Abstract: Warning systems have changed rapidly over the last centuries, from local personal warnings to radio to TV news up to other governmental channels such as modern warning apps. Still, a rather untouched area in this regard is the role of

Abstract: Cable landing stations (CLS) are facilities that host components required for the operation of subsea data cables (SDC) and facilitate their interconnection with terrestrial networks. SDC have an essential role for the secure operation of internet communication. However, as

Abstract: Submarine Data Cables (SDCs) are critical infrastructures that handle the majority of global network traffic. Despite their importance, SDCs receive limited media coverage and public attention, which creates significant gaps in understanding their vulnerabilities and significance. This thesis explores

As the prevalence of hate speech on social media continues to rise, there is an increasing rationale for the implementation of AI-based moderation systems. This study addresses the existing research gap in understanding how individual factors, including user familiarity with

Abstract: Disinformation and hate speech are often highlighted as major challenges within social media landscapes. While these phenomena have been extensively studied individually, their interconnection, particularly within the context of information warfare strategies, remains underexplored in empirical research. This thesis

Youth are particularly vulnerable to encountering hateful content online, which can significantly harm their well-being. Although most social media platforms offer reporting mechanisms, these systems often have shortcomings, such as an one-size-fits-all approach and a lack of adequate social support

Social Media has become an essential component of contemporary crisis management and communication strategies, and its value across various natural or human-induced emergency events is well-attested. However, studies that offer explanatory factors for citizens’ divergent risk perception and behavior before,

Einstein famously described quantum phenomena as "spukhafte Fernwirkung"—spooky action at a distance—a concept that challenged classical understanding. While, these same quantum principles have the potential to propel us into a new computational era, promising unprecedented processing power, they also pose a

The ongoing digitalization of critical infrastructures has significantly increased their dependence on internet connectivity. Disruptions to essential submarine cables, which form the backbone of internet access, can abruptly isolate highly digitalized regions from the internet for extended periods. The rapid
