Book excerpt: This book examines bullying and victimization at different points across the lifespan, from childhood through old age. It examines bullying at disparate ecological levels, such as within the family, in school, on the internet, at the work place, and between countries. This volume explores the connections between variations of bullying that manifests in multiple forms of violence and victimization.

The prevalence of bystanders and their behavior in bullying dynamics. The relationship between traditional bullying and cyberbullying. How bullying causes trauma. Sibling violence and bullying.
