The results are in after a year-long study on body-worn cameras by Las Vegas Metropolitan Police officers.

Analysts from the nonprofit research organization CNA, working with the Las Vegas Metropolitan Police Department and researchers from the University of Nevada Las Vegas, have released new research on the impact of body-worn cameras (BWCs). The study, funded by the U.S. Department of Justice’s National Institute of Justice, concluded that BWCs are associated with significant reductions in complaints of police misconduct and police use of force incidents. The study also determined that BWCs can generate considerable cost savings for police by simplifying the complaint resolution process.

Body cameras are reducing the Las Vegas Metropolitan Police Department's use of force but also building public trust, according to a new year-long study examining how the cameras affect police work.

According to a recent study by American researchers, married men who change their name to take their wife's name would lose their "dominant male" status within the couple. In contrast, wives who choose to keep their maiden name are seen as powerful and ambitious.

Researchers said a yearlong study into the Metropolitan Police Department’s use of body-worn cameras showed a decrease in police misconduct, complaints and use of force.

While most women still take their husband's surname after they marry, various alternatives have become more popular in recent years. Husbands take their wives' surnames, some couples combine their surnames and, of course, women are increasingly shunning the practice altogether and keeping their own names.

More than 80 per cent of Australian women take their husband's name when they marry. Each to their own, but this one has always puzzled me.

The findings published in Sex Roles: A Journal of Research suggest that when a married woman does not use the surname of her husband, people tend to view the man as effeminate.
