In my Criminology class, I used to lecture about “ecological theories” of crime. For example, the “ecology of bars” lend themselves to violence. Basically, ecological theory says that if you put together young males, alcohol, and guns, someone is more likely to get hurt than if any one of the tree elements is removed. Remove any one of the three, and the danger goes down. Which is why the youngest males are not allowed in bars, there are hours after which alcohol is no longer served, and you are to leave your guns outside the bar. Anyway some really smart criminologists thought this all up in the 1970s and 1980s, and published a whole bunch of books to make this point.
On the other hand, Johnny Cash had pretty much the same thoughts in the 1950s or so, and put them to music. Here it is: Ecology of Crime theory by the ethnographer Johnny Cash!
Tony Waters is czar and editor of Ethnography.com. He came to us from the Sociology department at California State University at Chico where he has been a professor since 1996. In 2016 though he suddenly found himself with a new gig at Payap University in northern Thailand where he is on the faculty of the Peace Studies Department. He has also been a guest professor in Germany, and Tanzania. In the past, his main interests have been international development and refugees in Thailand, Tanzania, and California. This reflects a former career in the Peace Corps (Thailand), and refugee camps (Thailand and Tanzania). His books include: Crime and Immigrant Youth (1999), Bureaucratizing the Good Samaritan (2001), The Persistence of Subsistence Agriculture: Life Beneath of the Marketplace (2007), When Killing is a Crime (2007), and Schooling, Bureaucracy, and Childhood: Bureaucratizing the Child (2012). His hobby is trying to learn strange languages–and the mistakes that that implies. Tony is a prolific academic, you can read more of his work at academia.edu.or purchase one (or more!) of his books from Amazon.com.
