Item Restricted Understanding and Predicting the Behavioural Evolution of Promotional Spambots on Social Media(University of Birmingham, 2025-05-15) Alzahrani, Ohoud; Hendleym BobSocial media bots are rapidly evolving, rendering traditional detection tools increasingly ineffective as these bots adapt their strategies. This research introduces a dynamic and predictive framework for modelling the behavioural evolution of online promotional spambots. Inspired by biological DNA, bot activities are encoded into behavioural sequences, with each block capturing seven distinct post-level features. Techniques such as sequence alignment, cosine similarity, and hierarchical clustering are used to group bots into behaviourally similar “families.” These families serve as the foundation for identifying behavioural mutations—insertions, deletions, substitutions, and alterations—that signal adaptive strategy changes. The model evaluates how these mutations propagate within and across bot families and investigates their predictive power through mutation transfer analysis and an event-driven case study. Results show that bots within the same family are significantly more likely to share and adopt behavioural mutations than those from different families. Closely related bots achieved high precision and F1 scores (up to 0.97) in mutation transfer prediction. These findings support the feasibility of a behavioural evolution model as a scalable, interpretable, and adaptive tool for anticipating future bot activity and offering a proactive approach to combating evolving threats on social media platforms.13 0Item Restricted The Relationship Between Childhood Trauma and Adult Aggressive Behaviour(2022) Alomayrini, Hamad; Yaneva, Mira; Dymond, HarrietRelationships connecting different kinds of childhood trauma with the aggressive behaviour in adulthood have been previously investigated. The majority of the studies have shown that childhood trauma could potentially lead to an adult aggressive behaviour in adulthood. This current study aims to investigate this hypothesis as well as to determine the potential factors in childhood trauma that could increase the adult aggressive behaviour. In that intention, an online survey was prepared using the "Adverse Childhood Experiences (ACEs) Questionnaire" and "Buss Perry Aggression Questionnaire (BPAQ)" to assess the childhood trauma experiences and the aggressive behaviour aspects of 100 participants. In the data analysis, the ACEs and BPAQ scores were calculated for each individual, and then a statistical analysis was performed. The results have shown that the childhood trauma exposure was directly linked to an adult aggressive behaviour. In addition, the regression models showed significant positive correlations between the childhood trauma and all the types of the aggressive behaviour. In conclusion, and in view of the obtained results, in addition to previous literature, it is extremely important to increase awareness about this subject for all parents, guardians and caregivers, in order to prevent childhood trauma in the first place and therefore adult aggression.41 0
