I have just published a selection of my work in the Chinese journal of criminology Issues on Juvenile Crime and Delinquency. This is the reference:
Federico Varese (2013, in Chinese), 'Heishoudang chansheng he zhuanyi lilun gaishu' [The theories of mafia emergence and transplantation], Issues on Juvenile Crime and Delinquency, 32:01, pp. 26-34.
In the same issue, there are papers by Diego Gambetta and Ben Bowling (among the non-chinese authors). There are also sections on child abuses, youth justice and much more.
In case you read chinese, the PDF is attached. Peng Wang has translated my text.
