Jonathan Shepherd is a maxillo facial surgeon in Cardiff. Alas much of his work was created by people bashing the faces of their fellow human beings, so he developed a career interest in violence and its prevention. In this paper, he pushes beyond the statistics to underlying causes with a qualitative study: why is violence more common in resource-poor communities? Actually, calling them 'resource-poor' rather than 'deprived' already gives you half the answer.
I was going to have a little grumble about the write-up but they trumped me: 'This study is reported in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ).'
