UCLA mathematicians working with the Los Angeles Police Department to analyze crime patterns have designed a mathematical algorithm to identify street gangs involved in unsolved violent crimes. Their research is based on patterns of known criminal activity between gangs, and represents the first scholarly study of gang violence of its kind.
The research appears today on the website of the peer-reviewed mathematical journal Inverse Problems and will be published in a future print edition. (more…)
If it was easy to learn, it will be easy to remember. Psychological scientists have maintained that nearly everyone uses this simple rule to assess their own learning.
Now a study published in an upcoming issue Psychological Science, a journal of the Association for Psychological Science, suggests otherwise: “Individuals with different theories about the nature of intelligence tend to evaluate their learning in different ways,” says David B. Miele of Columbia University, who conducted the study with Bridgid Finn of Washington University in St. Louis and Daniel C. Molden of Northwestern University. (more…)
Lesbian, gay and bisexual (LGB) adolescents are about 40 percent more likely than other teens to be punished by school authorities, police and the courts, according to a study by Yale University researchers. Published in the January 2011 issue of the journal Pediatrics, the study is the first to document excessive punishment of LGB youth nationwide.
“We found that virtually all types of punishment—including school expulsions, arrests, juvenile convictions, adult convictions and especially police stops—were more frequently meted out to LGB youth,” said lead author Kathryn Himmelstein, who initiated the study while she was a Yale undergraduate. The research was supervised by Hannah Brueckner, professor of sociology and co-director of the Center for Research on Inequalities and the Life Course at Yale. (more…)
