"The five reports that make up this collection are variously concerned with humanitarian aid, social and cultural evolution, crisis response, the mitigation of cultural divides, and political unrest. The themes that bind them are an international movement towards public safety; a trust-based relationship between states and citizens; community led social development; and the capacity of social media and big data to make use of, and amplify, the thoughts and voices of under-represented elements of society. Importantly, the reports also begin to question the inluence these violent contexts are having on the development of social media, where communities in crises utilise and shape these new technologies though real-time engagement. The potential of these media is being maximised to such an extent that these platforms are under strain, and developers are increasingly learning how to adapt to the needs of a variety of audiences in volatile contexts."
